Description

A kind of vehicle clamper that can quick-replaceable part to be processed
Technical field
The invention belongs to clamp for machining technical field, be specifically related to a kind of vehicle clamper that can quick-replaceable part to be processed.
Background technology
At present, existing vehicle clamper is subject to the impact of three characteristic parameters of part to be processed (three characteristic parameters are endoporus, end face diameter and axial dimension), in the time that any one parameter changes or exceedes certain excursion, fixture all needs to re-start Design and manufacture, and versatility is poor.Like this, not only increase the cost that fixture drops into, and made to switch converted products time and greatly increase, affected production efficiency.
Summary of the invention
The object of the invention is to overcome the shortcoming of above-mentioned prior art, a kind of vehicle clamper that can quick-replaceable part to be processed is provided, this vehicle clamper not only cost is low, and it is short to switch the converted products time, and production efficiency is high.
For achieving the above object, the technical solution used in the present invention is: comprise the body being arranged on platen, the front end of body is provided with the pull bar being connected with lathe oil cylinder; On pull bar, be connected with in the time that lathe oil cylinder drives pull bar motion and match with body front end and realize the ringfeder that steps up or unclamp part to be processed; Ringfeder and pull bar are integral type structure; Adding man-hour, part to be processed is set on ringfeder.
The front end of described body is the taper that diameter reduces; Ringfeder is the bonding hollow cylindrical structure forming, and offer the taper hole matching with body front end tapering part, and the diameter of ringfeder front end face taper hole is less than the diameter of end surface taper hole thereafter on an end face of ringfeder; The other end of ringfeder offers the stepped hole matching with pull bar.
The middle part of described body is provided with boss, in the time that part to be processed is installed, is set with successively interior adjustment pad and external-adjuster pad for control part to be processed axial dimension and locating surface size in the time processing between boss and part to be processed.
Described interior adjustment pad and external-adjuster pad are bolted on body.
Compared with prior art, the present invention has following beneficial effect:
The present invention installs pull bar at body front end, and on pull bar, be connected to when lathe oil cylinder drives pull bar motion and match with body front end and realize the ringfeder that steps up or unclamp part to be processed, drive pull bar motion by lathe oil cylinder, pull bar drives ringfeder, body front end is matched with ringfeder, realize stepping up or unclamping of part to be processed; Ringfeder and the pull bar formula structure that is processed as one, makes after processing, and pull bar can drive ringfeder to move vertically together, and ringfeder is unclamped, in the time that ringfeder unclamps, part can be realized part realization and unclamp voluntarily, thereby can reduce costs, improve machining accuracy and working (machining) efficiency.
Further, the present invention is provided with one for the boss of interior adjustment pad and external-adjuster pad is installed on body, and interior adjustment pad and external-adjuster pad are used for respectively controlling axial dimension and locating surface size; Carry out Seriation Design and handling design fast simultaneously, add and can combine as required selection man-hour.Reduced pad quantity, select conveniently, change quick.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail:
Referring to Fig. 1 to Fig. 3, the present invention includes the body 1 being arranged on platen, the front end of body 1 is provided with the pull bar 5 being connected with lathe oil cylinder, is connected with in the time that lathe oil cylinder drives pull bar 5 to move and matches with body 1 front end and realize the ringfeder 4 that steps up or unclamp part to be processed 6 on pull bar 5; Adding man-hour, part to be processed 6 is set on ringfeder 4.Ringfeder 4 and pull bar 5 are for after processing, and pull bar 5 can drive ringfeder 4 to move vertically together, and the integral structure that ringfeder 4 is unclamped.The front end of body 1 is the taper that diameter reduces; As shown in Figure 2, ringfeder 4 is the bonding hollow cylindrical structure forming, and offers the taper hole matching with body 1 front end tapering part on an end face of ringfeder 4; As shown in Figure 3, the diameter of ringfeder 4 front end face taper holes is less than the diameter of end surface taper hole thereafter; The other end of ringfeder 4 offers the stepped hole matching with pull bar 5.The middle part of body 1 is provided with boss, in the time that part to be processed 6 is installed, is set with successively interior adjustment pad 2 and external-adjuster pad 3 for control part to be processed 6 axial dimensions and locating surface size in the time processing between boss and part to be processed 6.Interior adjustment pad 2 and external-adjuster pad 3 are bolted on body 1.
Principle of the present invention:
When part to be processed location internal orifice dimension changes or endoporus length variations exceedes certain limit, need to redesign ringfeder, even need to redesign body; In the time that ringfeder unclamps, part sometimes can not unclamp voluntarily and need to knock just and can take off.For this reason, ringfeder is designed to bonding ringfeder structure, improves the scope of application of ringfeder; Ringfeder and pull bar are designed to the kit form of integral structure, and in the time that ringfeder unclamps, part can be realized part realization and unclamp voluntarily.Thereby can reduce costs, improve machining accuracy and working (machining) efficiency.
In part to be processed location, hole dimension and face size change while exceeding certain limit, and body needs new design, changes.Current product parameters is considered as a whole, divided three different size ranges, body carries out Seriation Design.Three serial bodies can meet the needs of production, and have greatly reduced the kind of body, have reduced stock, cost, have improved the product speed of changing.
The size of pad is relevant with the face size of part to be processed, axial dimension and location endoporus, and influenced many factors often needs design, changes.Influence factor is decomposed, and gasket design becomes inside and outside two to adjust pad, controls respectively axial dimension and locating surface size; Carry out Seriation Design and handling design fast simultaneously, add and can combine as required selection man-hour.Reduced pad quantity, select conveniently, change quick.
The course of work of the present invention:
First, select applicable body series and ringfeder rod assembly according to the location diameter of bore of part to be processed, ringfeder rod assembly will match with body series.
Secondly, match inside and outside adjusting pad (will consider the size of locating surface while selecting external-adjuster pad) according to axial dimension, meet the requirement of part to be processed axial location by the combination of inside and outside adjusting pad.
While loading and unloading inside and outside adjusting pad, can bolt not screwed down completely, only need unclamp.When adjustment, can be according to actual conditions, suitable external adjusting pad end face carries out turning, to ensure machining accuracy.
After processing, pull bar can move together vertically with ringfeder, and ringfeder is unclamped.
Above content is only explanation technological thought of the present invention; can not limit protection scope of the present invention with this; every technological thought proposing according to the present invention, any change of doing on technical scheme basis, within all falling into the protection domain of the claims in the present invention book.
