Abstract

The utility model relates to a chamfering machine for producing a vehicle piston pin, which comprises a lathe bed, left and right power heads arranged on the lathe bed, a base arranged between the left and the right power heads, a clamp arranged on the pedestal and a V-shaped locating block arranged on the clamp. The chamfering machine also comprises upper, lower, left and right first adjusting mechanisms which are arranged between the V-shaped locating block and the clamp to control the V-shaped locating block to go up and down along a Y shaft direction and the rotation freedom of motion of a Z shaft, a gyration centre arranged between the base and the central position of a workpiece, second adjusting mechanisms which are arranged on both sides of the front end of the base to control the rotation freedom of motion of the Y shaft of the V-shaped locating block, second adjusting mechanisms which are arranged on the front and the rear positions of the base to control the V-shaped locating block to move back and forth along the Z shaft and third adjusting mechanisms which are arranged between the left and the right power heads and the lathe bed. The chamfering machine for producing a vehicle piston pin has the beneficial effects of ensuring the precision processing of a machine tool and meeting the normal production requirements.

Description

Produce the beveler of piston pin of vehicle

Technical field

The utility model relates to a kind of beveler of producing piston pin of vehicle, relates in particular to the frame for movement that the location workpiece centre can be adjusted quickly and easily with respect to the left and right sides unit head centre of gyration.

Background technology

As seen from Figure 1: there is two 15 ° little chamfering at piston pin of vehicle 100 two ends, the shape requirement height, and axiality will be controlled in the 0.025mm, and employing projecting apparatus detection width deviation must not be greater than 0.1mm..Usually production can only be adopted the turning of workpiece rotation single head, and productivity ratio is lower.To further improve piston pin of vehicle productivity ratio, the technology that must adopt the piston pin double end to process simultaneously automatically, but the common double end beveler that present workpiece does not change all can't satisfy the high beat high-precision requirement of production.

By the accurate manufacturing process of present conventional lathe, all can not satisfy the long-time stability of the lathe of the axle class double end face work chamfering that workpiece do not change, this is the do not make a connection deadly defect of a precision of this type of workpiece.

Summary of the invention

The utility model technical issues that need to address have provided a kind of beveler of producing piston pin of vehicle, are intended to solve the above problems.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:

The utility model comprises: lathe bed, be placed in the left and right unit head on the lathe bed; Base in left and right unit head centre position; Anchor clamps on base and V-arrangement locating piece thereon; Also comprise: can control the V-arrangement locating piece up and down and first guiding mechanism rotary freedom, that be placed in the upper and lower, left and right between V-arrangement locating piece and the anchor clamps of Z axle along Y direction; At base and workpiece centre position a centre of gyration is set; One can control V-arrangement locating piece Y-axis rotary freedom, second guiding mechanism on the base front end left and right sides; Can control second guiding mechanism that the V-arrangement locating piece moves forward and backward along Z-direction, on the front and back position of base for one; One can control along the cutting depth of X-direction, be placed in the 3rd guiding mechanism between left and right unit head and the lathe bed.

Compared with prior art; the beneficial effects of the utility model are: make the little deviation that produces in the machine tooling, all can adjust to the right place in 2-3 minute, guarantee that lathe accurately processes; machining accuracy can be remained in the 0.025mm all the time, satisfy the ordinary production requirement.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:

By Fig. 2, Fig. 3 as seen: the utility model comprises: lathe bed 1, be placed in the left and right unit head 2 on the lathe bed 1; Base 3 in left and right unit head 2 centre positions; Anchor clamps 4 on base 3 and V-arrangement locating piece 5 thereon; Also comprise: can control V-arrangement locating piece 5 up and down and first guiding mechanism 6 rotary freedom, that be placed in the upper and lower, left and right between V-arrangement locating piece 5 and the anchor clamps 4 of Z axle along Y direction; In base 3 and workpiece centre position a centre of gyration 7 is set; One can control V-arrangement locating piece 5Y axle rotary freedom, second guiding mechanism 8 on the base 3 front end left and right sides; Can control V-arrangement locating piece 5 move forward and backward along Z-direction, second guiding mechanisms 9 on the front and back position of base 3 for one; One can control along the cutting depth of X-direction, be placed in the 3rd guiding mechanism 10 between left and right unit head 2 and the lathe bed 1;

Described first guiding mechanism 6, second guiding mechanism 8, the 3rd guiding mechanism 10 are to adjust screw.

The utility model adopts the accurate rapid adjustment mode of the full free degree, and is simple and practical: 1, the V-arrangement locating piece on the anchor clamps is by the adjustment of four screws up and down, can control the V-arrangement locating piece along Y direction up and down with the rotary freedom of Z axle.2, at base and workpiece centre position a centre of gyration is set, in excentric distant place, promptly base front end both sides are provided with two and adjust screw, can control the rotary freedom of V-arrangement locating piece Y-axis; 3, be provided with two at the front and back position of base again and adjust screws, can control the V-arrangement locating piece and move forward and backward along Z-direction.4, left and right sides unit head respectively is provided with a dead buting iron of precision positioning in X-direction, can control the cutting depth along X-direction.

Adjustment by said structure; make the little deviation that produces in any machine tooling; in 2-3 minute, all can adjust to the right place; guarantee that lathe accurately processes; make machining accuracy can remain in the 0.025mm all the time; satisfy the ordinary production requirement, make it to satisfy aborning the job requirement of at a high speed fast flat both ends of the surface of beat and chamfering (15/minute), work sustainedly and stably.

The utility model has significantly improved the productivity ratio (compare with the single head automatic turning, improve work efficiency 90%) of planar end surface and chamfering, and constant product quality satisfies the production and processing requirement, cost efficiency.The big profit of piston of automobile sales volume is thin, and therefore the utility model becomes the key equipment in the piston pin production, and can be popularized and applied to other similar production industries.
