Abstract

The invention relates to a chamfering machine for manufacturing an automobile piston pin. The chamfering machine comprises a bed body, a left power head and a right power head arranged on the bed body, a base arranged in the middle of the left power head and the right power head, a clamp on the base, a V-shaped positioning block on the clamp as well as an upper first adjustment mechanism, a lower first adjustment mechanism, a left first adjustment mechanism and a right first adjustment mechanism which can control the rotating degree of freedom of the V-shaped positioning block along the Y axis up and down and the Z axis and are arranged between the V-shaped positioning block and the clamp, a revolving center arranged on the base and the center of a workpiece, a second adjustment mechanism capable of controlling the rotating degree of freedom of the V-shaped positioning block along the Y axis and arranged on both sides at the front end of the base, another second adjustment mechanism capable of controlling the V-shaped positioning block to move back and forth along the Z axis and arranged in the longitudinal position of the base and a third adjustment mechanism capable of controlling cutting depth along the X axis and arranged between the left power head and the right power head and the bed body. The chamfering machine has the advantages of ensuring accurate machining of a machine tool and meeting the requirements of normal production.

Description

Produce the beveler of piston pin of vehicle

Technical field

The present invention relates to a kind of beveler of producing piston pin of vehicle, relate 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 technical issues that need to address of the present invention 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 present invention is achieved by the following technical solutions:

The present invention includes: 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 invention has the beneficial effects as follows: make the little deviation that produces in the machine tooling, in 2-3 minute, all can adjust to the right place, 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 present invention is described in further detail:

By Fig. 2, Fig. 3 as seen: the present invention includes: 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 present invention 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 present invention has significantly improved the productivity ratio of planar end surface and chamfering and (has compared with the single head automatic turning, carry High efficiency 90%), constant product quality satisfies the production and processing requirement, cost efficiency. Piston of automobile The big profit of sales volume is thin, and therefore the present invention becomes the key equipment in the piston pin production, and can be popularized and applied to Other similar production industries.
