Description

Technical Field

[0001] The utility model relates to the technical field of tooling processing, in particular to a tooling structure of a processing center of a rotating shaft seat. Background Art

[0002] In the modern medical equipment manufacturing industry, the shaft seat is one of the core accessories, and its quality and precision are directly related to the operational stability and safety of the entire equipment. The shaft seat in this project is the main accessory customized for a well-known domestic medical equipment manufacturer. The material is 304 stainless steel, and the process route is a combination of investment casting and machining. It must meet the requirements of mass production. Since this product uses investment casting to produce blanks, the production of the shaft seat uses the investment casting process, which is a precision casting method that can produce castings with complex shapes and high precision. However, due to the special structural design of the shaft seat and the extremely high requirements of the drawings on form and position tolerances, especially the relative position accuracy of the center hole and the hole slot, the traditional investment casting and then machining method faces challenges. These challenges are mainly reflected in the following aspects:

[0003] Positioning accuracy problem: Traditional tooling has errors when positioning the shaft seat, resulting in deviations between the processed workpiece and the design drawings, affecting the overall performance of the equipment.

[0004] Insufficient clamping stability: During machining, the workpiece needs to be firmly clamped to prevent displacement during machining. However, the clamping mechanism of traditional tooling may not provide sufficient stability, especially during precision machining such as milling and drilling.

[0005] Difficulty in ensuring accuracy: The drawings have extremely high requirements for the shape and position tolerances of the shaft seat, especially the relative position accuracy of the center hole and the hole slot. Traditional processes are difficult to meet these high-precision requirements at one time.

[0006] Production efficiency issues: In traditional processes, mechanical processing often requires multiple steps and multiple clamping, which not only increases production time and cost, but also affects processing efficiency.

[0007] Multiple clamping leads to low efficiency: In order to ensure processing accuracy, traditional processes often require multiple clamping and correction, which not only increases production time and cost, but also reduces processing efficiency.

[0008] Processing consistency is difficult to ensure: Due to multiple clamping and adjustments, the consistency of processing quality between different batches of products is difficult to control, affecting product reliability and customer satisfaction.

[0009] Insufficient workpiece rigidity: During the machining process, insufficient workpiece rigidity may lead to dimensional deviation after machining, especially when performing high-precision drilling and milling. Utility Model Content
