Definitions

  • This invention relates to the field of mechanical arrangements in which one mechanical member is coupled to another, and more particularly to a male/female combination in which the male part is taper locked into the female part.
  • a number of taper lock arrangements are known in the art, in which a tapered male part is received in a complementarily tapered female part, the angle of the taper for each part being chosen so that the male part is mechanically locked in the female part.
  • a large number of rotary tools in a machine shop employ a Morse taper system for accommodat- ing a quick change of bits, drill chucks, rotatable clamping jaws, and the like in such machines as lathes, drill presses, and milling machines, as well as in heavy duty road building equipment, tractors, mining tools, etc.
  • a gentle impactive force e.g., a tap
  • a gentle impactive force on the male part in a direction away from the female part will serve to break the taper lock for easy removal of the male part and replacement by another male part, for example to replace worn bits or to change sizes of bits quickly and efficiently.
  • the present invention overcomes the aforementioned problems of the prior art by providing a taper lock system which employs the taper lock principles while minimizing, or avoiding altogether, a breaking of the taper lock between the male and female parts upon encountering excessive torsional forces between the male and female parts.
  • a taper lock arrangement comprising a female part having a non- conical shaped wedge receptacle formed therein, and a male plug part comprising a non-conical shaped wedge portion, the wedge portion fitting into the wedge receptacle in an insertion direction to effect a taper lock.
  • a taper lock arrangement comprising: a generally rectangular male part; and a female part having a generally rectangular opening therein for receiving the male part in an insertion direction; wherein the opening has a pair of interior surfaces converging in the insertion direction, the male part has a pair of external surfaces converging in the insertion direction, and the male fits into the opening in the insertion direction to effect a taper lock between the exterior converging surfaces and the interior converging surfaces.
  • the invention may assume a variety of design configurations using both converging interlocking walls and diverging interlocking walls, may use converging or diverging walls offset from one another on either side of a central insertion axis in order to simultaneously effect a bias of the male part against the female part, or may have symmetrical diverging or converging walls to avoid any bias of the male part against the female part.

  • Figure 1 shows a rotary spade drill bit assembly employing the concepts of the present invention, the Figure 1 representation being taken from Applicant's copending application entitled “ROTARY DRILL ARRANGEMENT” , filed simultaneously herewith and bearing U.S. Application Serial No. . in that copending application, a rotary spade drill 1 is basically comprised of three parts, a spade drill body 3, a spade insert 5, and a rotary cutter 7 mounted on the spade insert 5, the rotary cutter 7 being exposed to the material being drilled through a cutout in the lower right hand corner of the rotary spade drill body 3 as shown in Figure 1.
  • a spade insert 5 shown in detail in Figure 3, is axially inserted into an opening 15 of spade drill body 3 in an insertion direction 4, as best seen in Figure 2, and, using prior art techniques, would be inserted fully into opening 15 until the top surface 11 of the spade insert 5 abuts the stop surface 13 at the bottom of the opening 15, at which time a rivet 9 would be fixed in place.
  • the spade insert 5 may be provided with tapered walls 17 and 19 to effect a taper lock function with the opening 15 as will be described hereinafter. No rivet is required to hold the spade insert 5 in place, and the spade insert length will be sized so as to leave a slight gap 2 between the upper surface 11 of the spade insert 5 and the bottom 13 of the opening 15.
  • Figure 4 is a side view of the spade insert 5 showing a rotatable cutter 7 in place. It will be appreciated that, as the spade insert is rotated clockwise (as seen from the top of the drill) , and the rotary cutter 7 is pushed into the material to be cut or drilled, a rearwardly directed force will be transmitted to the portion of the spade insert 5 upon which the cutter 7 is mounted. It would be desirable, then, to insure that the rear surface of the spade insert 5 behind the rotary cutter 7 would be solidly supported by the female body portion 3, and this is accomplished by the present invention as will be evident from the discussion of certain embodiments to be described hereinafter.
  • the spade insert 5 when the invention is used as the coupling means for mounting a spade insert into a rotary spade drill body, the spade insert 5 must extend a small distance at the sides and at the bottom of the female body 3 , in order to expose the cutting edges of the spade insert 5 to the material or substance being cut or drilled without interference by the body 3.
  • Figure 5 shows a male plug part 29 and female receptacle 31, the receptacle 31 having an opening 33 designed and configured to receive the male plug 29 in an insertion direction, i.e. in the direction of the arrowed lead line 40.
  • the dashed lines in Figure 5 indicate that the end walls 32 and 24 may be removed without functionally affecting the operation of the various embodiments of the invention.
  • the male part 29 in Figure 5 has a top surface 21, a bottom surface 23, a tapered exterior wall 47 on one side, and an opposing exterior tapered wall 49 on the opposite side of the male part 29.
  • the slope of the tapered wall 47 is such that the wedge 36 is wider at the bottom 23 than it is at the top 21.
  • the wedge 38 formed by the tapered wall 49 is wider at the bottom 23 than it is at the top 21.
  • the opening 33 also has tapered walls 35 and 37 which have a taper that is complementary to that of tapered walls 47 and 49 of the male part.

  • Figure 8 is a bottom view of the male part of Figure 7 showing, as in Figures 6 and 7, that the walls 47 and 49 of the male part 29 diverge in the insertion direction 40.
  • the tapered walls 47 and 49 are also planar in shape and are angled generally inwardly forming pointed edges 46 and 48, respectively. These pointed edges overlap corresponding and complementary pointed edges 35 and 37 on the female part ( Figures 5 and 11) in a dovetail-like fashion.
  • pointed edges such as 46 and 48 shown in Figure 8 are formed on the male and female parts, their purpose being to keep the engaged and taper locked surfaces 47 and 49 of the male part and 35 and 37 of the female part from moving laterally of the direction of insertion 40.

Abstract

Dispositif d'accouplement basé sur le principe du verrouillage conique mais présentant une partie mâle généralement rectangulaire et une partie femelle comportant une ouverture généralement rectangulaire servant à recevoir la partie mâle dans un sens d'insertion. Cette ouverture possède au moins une paire de surfaces intérieures convergentes ou divergentes dans le sens de l'insertion. La partie mâle possède au moins une paire de surfaces extérieures convergentes ou divergentes dans le sens d'insertion et la partie mâle s'introduit dans l'ouverture dans le sens d'insertion afin de réaliser un accouplement conique entre les surfaces extérieures convergentes ou divergentes et les surfaces intérieures convergentes ou divergentes. L'invention peut se présenter sous la forme d'une variété de configurations mettant en application à la fois des parois convergentes et divergentes de verrouillage réciproque, mettre en application des parois convergentes ou divergentes décalées les unes par rapport aux autres d'un côté ou de l'autre d'un axe d'insertion central, de façon à effectuer simultanément une sollicitation de la partie mâle contre la partie femelle, ou comporter des parois symétriques divergentes ou convergentes afin d'éviter toute sollicitation de la partie mâle contre la partie femelle.
