Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle parts processing, and particularly relates to a high-efficiency positioning equipment for suspension support processing. BACKGROUND

[0002] In the production and processing of vehicles, the balance suspension, as one of the automobile chassis parts, is an important component connecting the axle and the frame, and its function is to elastically connect the axle and the frame. The suspension support is mainly used to connect the balance suspension in the chassis and the frame, so as to fix the balance suspension on the frame and bear the load transmitted by the balance suspension when the vehicle runs on uneven road and turns, thereby ensuring the safety and comfort of the vehicle during running. Therefore, the processing precision of the suspension support is required to be high. In the production and manufacturing process of the suspension support, the suspension support needs to be positioned and fixed before processing, so as to ensure the accurate positioning and processing precision of the suspension support during processing, improve the product qualification rate and production efficiency of the suspension support, and prevent processing failure caused by inaccurate positioning.

[0003] However, the prior art mainly fixes the suspension support to be processed by manual operation of a clamp or a positioning forceps before processing, but this requires the operator to have high processing experience and professional skills, and slight errors may cause the suspension support to fail to be processed. There are also technologies for positioning and processing the suspension support by positioning equipment, such as the patent document with the publication number CN209830389U, which discloses a "suspension support bottom plane milling processing device". The device uses an electric push rod and a connecting plate to position the suspension support, and the automatic positioning efficiency is high. However, the positioning precision of the suspension support is low, because the suspension support has a certain weight and an irregular shape. The positioning and clamping precision of the above structure for the suspension support is not enough, which easily leads to low qualification rate of the processed suspension support, and further leads to low processing efficiency of the finished product.
