Problems solved by technology

However, the screw and the nut are usually in the form of thread fit. Because the thread is easy to wear, it is easy to cause the workpiece to loosen during the processing, so the thread positioning accuracy is relatively low, and there is a large error in the thread fit, which will affect the accuracy of the spoke processing. , which in turn affects the operation of the entire vehicle
Moreover, every time the spokes are clamped, the nuts need to be manually tightened, which is very cumbersome to operate and the production efficiency is low

Abstract

The invention belongs to the field of clamping devices or positioning devices of workpieces, and particularly discloses a spoke lathe clamp. The spoke lathe clamp comprises a clamp body and a positioning disc fixed to the clamp body. The spoke lathe clamp is characterized by further comprising an electromagnet and pull rods, the electromagnet is arranged on one side of the clamp body, magnets matched with the electromagnet are arranged at one ends of the pull rods, and protrusions are arranged at the other ends of the pull rods, wherein the diameter of the protrusions is larger than the hole diameter of a spoke; the pull rods penetrate the clamp body and are in clearance fit with the clamp body; and the positioning disc is provided with positioning pins. The positioning pins and the electromagnet are matched, a nut does not need to be screwed, the spoke installing and clamping time can be shortened, and production efficiency is improved.

Description

technical field [0001] The invention relates to the field of workpiece clamping devices or positioning devices, in particular to a spoke lathe clamp. Background technique [0002] With the rapid development of my country's automobile industry, the demand for products in the wheel manufacturing industry is also increasing. Modern machinery industry technology has also developed rapidly. The wheel spoke is a device for protecting the rim and spoke of the vehicle wheel. It is characterized by a pair of circular cover plates. The part near the edge of the plate has an opening, the edge of the cover plate has an annular wheel plate, and the curved surface of the wheel plate can closely fit the curved surface of the wheel rim. Automobile wheel spokes are important components in automobile manufacturing, and the machining accuracy and quality of their products will directly affect the running performance of the automobile. [0003] Spoke turning fixtures are generally used for s...
