Outer circle turning clamp for thin-walled parts for motor

Abstract

The invention discloses an outer circle turning clamp for thin-walled parts for a motor. The outer circle turning clamp comprises a central spindle, an expansion sleeve, a pressing plate and a compression nut. The central spindle is provided with a threaded section and a conical section. The end, with a smaller diameter, of the conical section is close to the threaded section. The compression nut is in threaded connection with the threaded section. The expansion sleeve is a polyurethane expansion sleeve. The inner work face of the expansion sleeve is provided with a conical hole, and the taper of the conical hole is matched with that of the conical section of the central spindle. The pressing plate is located between the compression nut and the expansion sleeve and is annular. The inner diameter of the pressing plate is smaller than the inner diameter of the expansion sleeve and larger than the large diameter of the threaded section, and the outer diameter of the pressing plate is larger than the outer diameter of the expansion sleeve. The outer circle turning clamp is easy to design and manufacture and suitable for small-batch production or single part production.

Description

technical field [0001] The invention relates to production equipment for processing motor parts, in particular to an outer circle clamp for motor thin-walled parts. Background technique [0002] The motor refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. It is represented by the letter M in the circuit. Its main function is to generate driving torque as a power source for electrical appliances or various machinery. There are motors on the motor. Lots of thin-walled parts. [0003] It is generally believed that in shell parts, sleeve parts, ring parts, disc parts, flat parts, and shaft parts, when the ratio of the part wall thickness to the inner diameter radius of curvature (or contour size) is less than 1:20, it is called thin-walled parts. The common characteristics of these parts are low rigidity and complex structure, which can easily cause error deformation or workpiec...

Problems solved by technology

Liquid plastic is melted and boiled from polyvinyl chloride resin, dibutyl diformate, and calcium stearate. It has a certain consistency and viscosity, but when the gap between the workpiece and the fixture is large (greater than 0.05mm) , liquid plastics are prone to leakage, and the clamping force transmitted by the fixture to the workpiece is also very unstable, or the workpiece cannot be clamped. Therefore, the design, processing and manufacturing of the fixture itself are complicated, and the manufacturing cost is high, so it is difficult to be used for small batches of workpieces. processing
