Abstract
The invention discloses a press operating platform positioning device, which comprises a base seat. A movable operating platform is assembled above the base seat, a positioning cone pin is installed inside the base seat, a positioning cone seat tightly fitted with the positioning cone pin is arranged at the bottom part of the movable operating platform, and low-melting alloy for fixing the positioning cone pin is filled in the gap between the positioning cone pin and the base seat. The technical process comprises the following steps that: firstly the positioning cone seat is positioned, secondly the low-melting alloy is filled in the cavity gap between the positioning cone pin and the base seat, thirdly the movable operating platform and the base seat are accurately positioned through thetight fitting of the positioning cone pin and the positioning cone seat, thereby improving the traditional technical process which depends on process precision to ensure the accurate positioning of the movable operating platform and the base seat.
Description
Technical field
The present invention relates to a kind of installation method of positioner of workbench.
Background technology
At present, positioning accuracy between moveable platform of press and the base guarantees by the precision of use equipment and operator's technical merit mostly, because moveable platform of press and base are all large-size workpiece, when machining, its machining accuracy will be difficult to satisfy the precision needs of forcing press, the travelling table location is inaccurate, and the location between moveable platform of press and the base directly influences the machining accuracy of the workpiece of being processed.
The utility model content
Technical problem to be solved by this invention provides a kind of simple in structure, easy to operate, makes the installation method of the positioning device for press bench of moveable platform of press and base accurate positioning.
For solving the problems of the technologies described above, technical scheme of the present invention is: positioning device for press bench, comprise base, the top of described base is equipped with travelling table, the location taper pin is installed in the described base, the bottom of described travelling table is provided with described locating cone and locks leakproof fit locating cone seat, is filled with the low-melting alloy of fixing described location taper pin in the gap of described location taper pin and described base.
The installation method of above-mentioned positioning device for press bench is: the locating cone seat after will processing earlier is fitted into travelling table, to locate after taper pin is fitted into base, travelling table and base are accurately located, travelling table and seat guarantee 0.3～0.6mm gap, at this moment, accurately measure this gap, then the locating cone seat is carried out secondary operations, promptly eliminate this gap by the mating surface of grinding locating cone seat and travelling table; Assembling and positioning is bored seat and location taper pin once more, fastening locating cone seat, the location taper pin wouldn't be fastening, then travelling table and base are accurately located, after locking locating cone admittedly, travelling table is shifted out, low-melting alloy is heated to 250 ℃ of-350 ℃ of fusings filled the cavity clearance that forms between location taper pin and the described base afterwards, travelling table and base are accurately located by described location taper pin and described locating cone seat.
Owing to adopted technique scheme, positioning device for press bench, comprise base, the top of described base is equipped with travelling table, the location taper pin is installed in the described base, the bottom of described travelling table is provided with described locating cone and locks leakproof fit locating cone seat, is filled with the low-melting alloy of fixing described location taper pin in the gap of described location taper pin and described base.By repeatedly processing to the locating cone seat, locating cone seat and travelling table are closely cooperated, then by wouldn't fastening location taper pin, assembling and positioning awl seat and location taper pin, after making the location taper pin be positioned at the suitable position of base, fastening location taper pin, fill the low-melting alloy of stationary positioned taper pin and described base then in the gap that between location taper pin and described base, forms, make closely cooperating together of location taper pin and locating cone seat, thereby travelling table and base are accurately located, improved the process that traditional dependence machining accuracy guarantees travelling table and base positioning accuracy.
Description of drawings
Accompanying drawing is the structural representation of the embodiment of the invention.
The specific embodiment
As shown in the figure, positioning device for press bench, comprise base 2, the top of described base 2 is equipped with travelling table 1, location taper pin 4 is installed in the described base 2, the bottom of described travelling table 1 is provided with and described location taper pin 4 close-fitting locating cone seats 5, is filled with the low-melting alloy 3 of fixing described location taper pin 4 in the gap of described location taper pin 4 and described base 2, and described low-melting alloy 3 is ashbury metal, metal or kirsite.
Locating cone seat 5 after will processing earlier is fitted into travelling table 1, to locate after taper pin 4 is fitted into base 2, travelling table 1 and base 2 are accurately located, travelling table 1 guarantees 0.3～0.6mm gap with base 2 mating surfaces, at this moment, accurately measure this gap, then locating cone seat 5 is carried out secondary operations, promptly eliminate this gap by the grinding locating cone seat 5 and the mating surface of travelling table 1; Assembling and positioning is bored seat 5 and location taper pin 4 once more, fastening locating cone seat 5, location taper pin 4 wouldn't be fastening, then travelling table 1 and base 2 are accurately located, to locate taper pin 4 fastening after, travelling table 1 is shifted out, and is that ashbury metal, metal or kirsite etc. are heated to the cavity clearance that formation between location taper pin 4 and the described base 2 was filled in 250 ℃ of-350 ℃ of fusings afterwards with low-melting alloy 3, by described location taper pin 4 and described locating cone seat 5 travelling table 1 and base 2 is accurately located.
When travelling table 1 assembles with base 2, by fine finishining to locating cone seat 5, locating cone seat 5 and travelling table 1 are closely cooperated, by wouldn't fastening location taper pin 4, assembling and positioning awl seat 5 and location taper pin 4, after making location taper pin 4 be positioned at the suitable position of base 2, fastening location taper pin 4, fill low-melting alloy 3 in the cavity clearance that between location taper pin 4 and described base 2, forms then, like this by the close fit of location taper pin 4 with locating cone seat 5, travelling table 1 and base 2 are accurately located, improved the process that traditional dependence machining accuracy guarantees travelling table 1 and base 2 positioning accuracies.
