Embodiment Construction

[0017] Below, the spring steel sheet traceless electrophoresis device of the present invention will be described in detail in conjunction with the accompanying drawings and embodiments:

[0018] Such as Figure 1~3 As shown, a spring steel sheet traceless electrophoresis device includes a positioning sleeve 1, a shielding sleeve 2 and a positioning mandrel 4. The positioning mandrel 4 passes through the center hole of the workpiece 3 to fix the workpiece 3 on the positioning sleeve 1. The positioning sleeve 1 includes a positioning sleeve body 5 with a stepped shape, and a stepped blind hole is formed inside the right end of the positioning sleeve body 5. The inner diameter of the stepped blind hole decreases from left to right, and the right end of the stepped blind hole is A circular groove 6 is provided with a shielding sleeve 2 in the circular groove 6. The left end of the stepped blind hole is an internal thread 7, and a semicircular groove 8 is formed on the left end of ...

Abstract

The invention discloses a spring steel sheet mark-free electrophoresis apparatus, which comprises a positioning sleeve, a screening sleeve and a positioning mandrel. The positioning sleeve comprises a step-shaped positioning sleeve body. A step blind hole is formed in the right end of the positioning sleeve body. A circular groove is arranged at the right end of the step blind hole. The screening sleeve is arranged in the circular groove. A female thread is arranged at the left end of the step blind hole. A semicircular groove is formed at the left end of the positioning sleeve body. The positioning mandrel comprises a positioning mandrel body. The positioning mandrel body is a reducing cylinder. A male thread is formed at the left end part of the positioning mandrel body. The spring steel sheet mark-free electrophoresis apparatus has the advantages of good processing quality, high efficiency and low cost. Applicable materials of the screening sleeve are high-temperature-resistant, anticorrosive and nonconductive materials with certain elasticity, such as silicon rubber and polytetrafluoroethylene.

Description

technical field [0001] The invention belongs to an electrophoresis device, in particular to a trace-free electrophoresis device of a spring steel sheet which needs to be partially covered without electrophoresis and has no traces of hanging points. Background technique [0002] The spring steel sheet used in some industrial production needs to cover the electrophoresis that does not require electrophoresis and has no traces of hanging points. For example, the shape is a thin disc, the thickness is about 0.8mm, the inner hole is about 14mm and there is a hole on one side. Chamfering, on the chamfering surface, there is a ?25mm assembly mating surface that is the same as the center of the inner hole. No electrophoretic layer is required. The surface quality requirements of the outer electrophoretic layer are relatively strict. Points and other defects, the processing requirements are more stringent. [0003] Due to the relatively strict surface quality of the electrophoreti...
