Abstract
The utility model discloses a large-part tooling positioning pin adjusting device comprising a base. The base is provided with two L-shaped fixed supports fixedly connected with the base, a positioning pin used for positioning a part tooling is fixed on each fixed support, and an adjusting support is arranged in the L-shaped space of each fixed support. Adjusting gaskets are arranged between neighboring sides of the adjusting supports and the fixed supports. The adjusting supports and the fixed supports are fixed through fastening screws. By unscrewing the fastening screws and connecting bolts of the adjusting supports, the adjusting supports are loosened, the adjusting gaskets are taken out, accurate sizes of two positioning pin holes of the part can be processed according to needs, and the calculated adjusting gaskets can be replaced on; the tooling can be accurately positioned, and requirements for processing quality of the part are met.

Technical field
The utility model relate to a kind of heavy parts in positioning and clamping debugging, carry out fast can accurate adjustment positioner, belong to heavy parts tool locating and adjust field.
Background technology
For the higher large product part of dimension precision requirement, when actual converted products part, there is the situation of mutually interfering in the theoretical value size of the position degree of technology hole and the dimensional accuracy in hole and design of happening occasionally, at this time product parts is not easy to be put in alignment pin.By former method adjustment, be that alignment pin is launched, according to the actual accurate to dimension of part, re-start calculating, modification, adjust, sometimes will re-start machined.Have a strong impact on service property (quality) and the efficiency of frock.
Utility model content
The utility model is non-adjustable for existing location technology, provides a kind of rational in infrastructure, and design is accurate, easy to manufacture, and commissioning is convenient, a kind of heavy parts adjustable positioning pin device of quality assurance.
The utility model is achieved through the following technical measures:
A kind of heavy parts tool locating pin adjusting device, comprise base, described base is provided with two L-type hold-down supports that are fixedly connected with it, on each hold-down support, be fixed with the alignment pin for part tooling is positioned, and be respectively provided with an adjustment bearing in the L-type space of each hold-down support; Between adjustment bearing and the adjacent edge of hold-down support, be provided with adjustment pad; And by trip bolt, fix between described adjustment bearing and hold-down support.
In adjustment bearing described in two, be provided with stationary bushing, and in a stationary bushing, be provided with and be provided with to adjusting in cylindrical positioning pins that bearing positions, another stationary bushing the diamond positioning pin positioning adjusting bearing.
On described adjustment bearing, screw in the screw that has anti-its rotation.
Assembly method of the present utility model is as follows:
First hold-down support is assemblied on base and with assembling and positioning pin and is fixed, again adjustment bearing is assemblied on base, stationary bushing is assembled in respectively and is adjusted in bearing, and cylindrical positioning pins, diamond positioning pin are put into stationary bushing, put into respectively adjustment pad, commissioning size A ± 0.001, B ± 0.001, fixedly tighten with connecting bolt after commissioning simultaneously, anti-turn screw is screwed into and is adjusted on bearing, be finally screwed into trip bolt.
Adjustment method of the present utility model:
Unclamp trip bolt, unscrew the connecting bolt of adjusting bearing, make to adjust pedestal looseness, take out and adjust pad, according to the accurate dimension of product parts two dowel holes of reality processing.Change the adjustment pad calculating.So just can adjust soon the accurate location of frock.Guarantee the crudy requirement of product parts.
The beneficial effects of the utility model are as follows:
By unclamping trip bolt, unscrew the connecting bolt of adjusting bearing, make to adjust pedestal looseness, take out and adjust pad, according to the accurate dimension of product parts two dowel holes of reality processing, change the adjustment pad calculating; Realize the accurate location to frock, guaranteed the crudy requirement of product parts.

The specific embodiment
Accompanying drawing has provided structural design schematic diagram of the present utility model:
Heavy parts tool locating pin assembly, comprise base 1, described base 1 is provided with the hold-down support 8 of two L-types that are fixedly connected with it, be fixed with the alignment pin 11 for part tooling is positioned, and a side of each holder is respectively provided with an adjustment bearing 9 on each hold-down support 8; Between adjustment bearing 9 and hold-down support 8, be provided with and adjust pad 7; And fixing by trip bolt 6 between described adjustment bearing 9 and hold-down support 8.Adjust on bearing and screw in and have anti-turn screw 4.
In adjustment bearing described in two, be provided with stationary bushing 3, and in a stationary bushing 3, be provided with and be provided with to adjusting in cylindrical positioning pins 2 that bearing positions, another stationary bushing the diamond positioning pin 5 positioning adjusting bearing.
Adjusting bearing fixes by connecting bolt 10 and base.
Specific implementation method is as follows:
1, each tool part is machined by layout design.
2, frock assembling: first hold-down support 8 is assemblied on base 1 and with assembling and positioning pin 11 and fixes, again adjustment bearing 9 is assemblied on base, stationary bushing is assembled in respectively and is adjusted in bearing, and cylindrical positioning pins 2, diamond positioning pin 5 are put into stationary bushing 3, put into respectively and adjust pad 7, commissioning size A ± 0.001, B ± 0.001, fixedly tighten with connecting bolt after commissioning simultaneously, anti-turn screw 4 is screwed into and is adjusted on bearing 9, be finally screwed into trip bolt 6.
3, adjustment method: unclamp trip bolt 6, unscrew the connecting bolt 10 of adjusting bearing 9, make to adjust bearing 9 loosening, take out and adjust pad 7, the accurate dimension according to product parts two dowel holes of reality processing, calculates the size of H ± 0.001.Change the adjustment pad 7 calculating.So just can adjust soon the accurate location of frock.Guarantee the crudy requirement of product parts.
