Abstract
The utility model relates to an assembly and disassembly tool for bolts, in particular to a special tool for stud bolts. The tool is characterized by comprising an inner ring body, an outer ring body and cylindrical rollers, wherein the inner ring body is a circular sleeve, and the inner ring body is sleeved in the outer ring body; the inner wall of the outer ring body is provided with at least three arc grooves along the circumferential direction; the inner ring body is provided with roller limiting holes corresponding to the arc grooves; the cylindrical rollers are arranged between the roller limiting holes and the arc grooves; when the tool is used for assembling or disassembling the stud bolt, the inner ring body is sleeved on the stud bolt, the outer ring body is pulled to rotate relative to the inner ring body, the arc grooves on the inner wall of the outer ring body press the cylindrical rollers, the cylindrical rollers move in the roller limiting holes along the radial direction of the inner ring body, the protruding parts of the cylindrical rollers at the inner side of the inner ring body clamp the stud bolt, and the outer ring body is continuously rotated to drive the stud bolt to rotate, so that the stud bolt is assembled on equipment or disassembled from the equipment. The utility model has the advantages that: the tool is easy to assemble and disassemble the stud bolts, simple in operation, time-saving and labor-saving.
Description
Technical field
The utility model relates to installation, the extracting tool of bolt, says it is a kind of specific purpose tool that is used for the stud installation and removal in detail.
Background technology
We know; in the installation of equipment and use, use stud through regular meeting; stud is installed on the equipment; at first two nuts to be installed successively on an end of stud; pull nut outside with spanner then the other end of stud is installed on the equipment, again two nuts are unloaded successively.When needs stud when equipment disassembles, equally two nuts need be installed successively on an end of stud, pulling inboard nut with spanner then unloads the other end of stud from equipment, again two nuts are unloaded successively, installation, the demounting procedure of stud are loaded down with trivial details, troublesome poeration, waste time and energy.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, provides a kind of installation to stud, dismounting easily, simple to operate, time saving and energy saving stud specific purpose tool.
The technical solution of the utility model is:
A kind of stud specific purpose tool, it is characterized in that comprising inner ring body, outer ring body and cylindrical roller, inner ring body is a circular sleeve, inner ring body is sleeved in the outer ring body, the outer ring body inwall along the circumferential direction is provided with three arc grooves at least, inner ring body and arc groove corresponding section are provided with the roller spacing hole, between roller spacing hole and arc groove cylindrical roller are installed.
The utility model can be provided with spacing preiection respectively in two ends up and down at inner ring body, and spacing preiection abuts on the upper and lower end face of outer ring body.
The width of roller spacing hole of the present utility model is less than the cylindrical roller diameter, and the ultimate range between arc groove and inner ring body is less than the cylindrical roller diameter.
When using the utility model installation or removal stud, inner ring body is enclosed within on the stud, pulling outer ring body rotates relative to inner ring body, arc groove on the outer ring body inwall presses cylindrical roller, cylindrical roller moves radially along inner ring body in the roller spacing hole, cylindrical roller clamps stud in the inboard part of protruding of inner ring body, is rotated further outer ring body, just can drive the stud rotation and it is installed on the equipment or from equipment unloads.Has easy disassembling, simple to operate, time saving and energy saving advantage to stud.
Description of drawings
Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 are a kind of structural representations of the present utility model.
Fig. 1 is a front view.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the A-A cutaway view of Fig. 1.
Fig. 4 is the structural representation of the utility model arc groove when compressing cylindrical roller.
Fig. 5 is the B-B cutaway view of Fig. 4.
The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, bolt disassembly instrument shown in Figure 5, comprise inner ring body 1, outer ring body 2 and cylindrical roller 5, inner ring body 1 is a circular sleeve, and inner ring body 1 is sleeved in the outer ring body 2, and inner ring body 1 and outer ring body 2 can relatively rotate.Outer ring body 2 inwalls along the circumferential direction are provided with three arc grooves 3 at least, and as can be seen, outer ring body 2 inwalls along the circumferential direction evenly are provided with three arc grooves 3 from Fig. 3, Fig. 4.Inner ring body 1 is provided with roller spacing hole 4 with arc groove 3 corresponding sections, 3 installations of roller spacing hole 4 and arc groove cylindrical roller 5, cylindrical roller 5 can be in roller spacing hole 4 moving radially along inner ring body 1.As can be seen, inner ring body up and down two ends is provided with spacing preiection 6,7 respectively from Fig. 1, Fig. 2, Fig. 5, and spacing preiection 6,7 abuts on the upper and lower end face of outer ring body, can limit inner ring body 1 and outer ring body 2 and relatively move enhancing instrument resistance to overturning between axially.The width of roller spacing hole of the present utility model is less than the cylindrical roller diameter, can prevent that cylindrical roller from deviating from from the inner ring body inboard; Ultimate range between arc groove and inner ring body is less than the cylindrical roller diameter, can prevent that cylindrical roller from deviating from arc groove.
During use during the utility model installation or removal stud, inner ring body is enclosed within on the stud, pull outer ring body and rotate relative to inner ring body, the arc groove on the outer ring body inwall presses cylindrical roller, and cylindrical roller is moving radially and protrude the inner ring body inboard along inner ring body in the roller spacing hole.Cylindrical roller is rotated further outer ring body after the inboard part of protruding of inner ring body clamps stud, just can drive the stud rotation and it is installed on the equipment or from equipment unloads.Has easy disassembling, simple to operate, time saving and energy saving advantage to stud.The outer ring body inwall along the circumferential direction evenly is provided with arc groove can make each cylindrical roller stressed evenly, avoids the screw thread on the excessive damage stud of local pressure.
The utility model can be established handle on inner ring body upper end or lower end, the periphery of outer ring body is made hexagon or establish handle on outer ring body, and is more convenient to operate to the dismounting of bolt.
