Problems solved by technology

[0003] ① Due to the injection molding method, it is easy to have defects such as lack of material or pores on the surface of the product; at the same time, the molding time is long and the production efficiency is low
[0004] ②Because there are iron parts inside the product, during injection molding, due to uneven cooling and heat, severe flashing or insufficient filling will appear at the contact part between the iron part and the elastic material, which will lead to a high scrap rate
[0005] ③Due to the existing processing methods, the dimensional accuracy of the product can only be controlled at about 0.5mm, which cannot meet the high-precision matching requirements of the products in the automotive industry

Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] The processing method of the outer elastic body of the automobile buffer block of the present invention comprises the following steps:

[0032] (1) A plurality of continuous buffer block blanks are injection molded by an injection molding machine;

[0033] (2) Fix the first special fixture capable of clamping the outer circular surface of the buffer block on the lathe, fix the tool with the groove on the inner surface of the car on the lathe carriage, then put the blank into the first special fixture, and turn on the power switch ;

[0034] (3) The turning tool enters the inner hole of the buffer block, and performs groove processing on the inner surface of the first buffer block until the preset groove depth and groove width requirements are reached, then stop feeding and withdraw the tool;

[0035] (4) After the tool is ret...

Abstract

The invention discloses a method for processing an automobile buffer block, which comprises the following steps: (1) injection-molding a buffer block blank by an injection molding machine; (2) fixing the buffer block blank to a lathe through a first special clamp capable of clamping an outer circle surface of the buffer block, and processing a lathe groove on the inner surface of the buffer block; (3) taking a semi-finished product of the buffer block out from the first special clamp, fixing the semi-finished product to the lathe through a second special clamp capable of clamping the inner surface of the buffer block, and cutting and processing the end face of the lathe; and (4) stopping processing and retracting a cutter, and mounting a previously-processed iron piece in the processed qualified buffer block. After the structure is adopted, the method can process a plurality of the buffer blocks once so as to greatly improve the production efficiency; and simultaneously, the phenomenon of flashing or deficient filling is not caused, the surface of the product is smoother, and the processing precision is higher.

Description

technical field [0001] The invention relates to the field of auto parts processing, in particular to a processing method of an auto buffer block and a special clamp used therefor. Background technique [0002] At present, shock absorbers are installed on automobiles, which can reduce the feeling of tilting when the vehicle is turning, and also reduce the feeling of bumps when the vehicle is driving on uneven roads. After a long time of use, the shock absorbers will harden and become Part of the comfort will be lost, so a buffer block is usually added to shorten the stroke and impact force of the shock absorber and shock absorbing spring for protection. The structure of the buffer block is generally a circular iron piece embedded in a cylindrical elastic material, and its production method is one-time injection molding, that is to say, a circular iron piece is placed in the mold first, and then it is injection-molded by an injection molding machine. However, this processing ...
