Problems solved by technology

[0003] The present invention mainly provides a fully flexible automotive steering rack grinding fixture that can clamp multiple workpieces at one time, and can be used for workpiece processing of various specifications. At the same time, the clamping and positioning accuracy is high, and the production cost is saved. In the existing technology, it is necessary to configure various types of fixtures to meet the processing requirements. Not only the cost of tooling is high, but also because the process of fixture replacement is time-consuming and laborious, resulting in low production efficiency and further increase in production costs.

Abstract

The invention discloses a grinding fixture which provides a full compliant motor steering rack grinding fixture has the advantages of clamping several workpieces at one time, being applied to a variety of workpieces process, having a high accuracy of clamped positioning and saving the cost of production. The full compliant motor steering rack grinding fixture solves the existing technical problems of needing multiple model fixture to meet processing needs, having high frock cost, having low production efficiency and further increase of production cost due to a change process of fixture is wasted time and energy. The full compliant motor steering rack grinding fixture comprises a square supporting platform. Several substrates which clamps the workpiece to keep horizontal are disposed on the supporting platforms in parallel. Two ends of the substrate are connected with the supporting platform and the substrate can spin around one of fixed end. When one of substrates spin around the fixed end, others substrates can be driven to spin parallelly and synchronously.

Description

technical field [0001] The invention relates to a grinding fixture, in particular to a fully flexible automotive steering rack grinder that can clamp multiple workpieces at one time, can be used for processing workpieces of various specifications, has high clamping and positioning accuracy, and saves production costs. Sharpening fixture. Background technique [0002] There are generally 5 to 7 stations on the existing automobile steering rack grinding fixture, and each station is a fixed structure. Dimensions (diameter and β angle) are also different, so each specification of automotive rack needs to be equipped with separate fixtures, that is, multiple sets of different types of fixtures are required to meet the daily processing of various steering racks. Not only the cost of tooling is high, but also Due to the time-consuming and laborious process of fixture replacement, the production efficiency is low and the production cost is further increased. Contents of the inven...
