Fixture for horizontal stroke lathe

Abstract

The invention discloses a fixture for a horizontal stroke lathe and belongs to the field of horizontal lathes. The fixture comprises a fixture body, a positioning plate, a handle, a plane cam, a tensioning structure and a plurality of pull rods; the fixture body comprises a fixed fixture body and a mobile fixture body which are arranged oppositely; the plane cam is located between the mobile fixture body and the fixed fixture body; the plane cam comprises a fixed cam and a mobile cam which are in abutting joint with each other; the tail end of the handle is fixedly connected with the mobile cam; the mobile cam is connected with the mobile fixture body in a rotating mode; the mobile cam can rotate and can move along the direction perpendicular to the rotating surface; the fixed cam is fixedly connected with the fixed fixture body; the positioning plate is arranged on one side of the fixed fixture body, wherein the side is far away from the mobile fixture body; the positioning plate is provided with a positioning pin; every pull rod penetrates the fixed fixture body; one end of every pull rod is connected with the mobile fixture body; the other end of every pull rod is connected with the tensioning structure. According to the fixture for the horizontal stroke lathe, the machining accuracy of a stroke can be improved, the clamping time of the stroke can be shortened, and the production efficiency can be improved.

Description

technical field [0001] The invention relates to the field of horizontal lathes, in particular to a fixture for processing wheel spokes. 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 spoke is a device to protect the rim and spoke of the vehicle wheel. It is characterized by a pair of circular cover plates. The diameter of the cover plate is close to the diameter of the wheel rim. There is a hole in the center of the cover plate that is larger than the rotation axis of the wheel. The part near the edge of the cover plate has an opening, and the edge of the cover plate is provided with an annular wheel plate, and the curved surface of the wheel plate can fit closely with the curved surface of the wheel rim. Automobile wheel spokes are important parts in automobile manufacturing, and...

Problems solved by technology

Because the thread is easy to be worn, 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, and then affect the operation of the entire car

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
