Description

Technical Field

[0001] The utility model relates to the technical field of mechanical tooling, in particular to a multifunctional mechanical tooling fixture. Background Art

[0002] During mechanical processing, it is necessary to use a fixture to clamp the workpiece so as to perform mechanical processing such as welding, cutting, and cutting on the workpiece. According to a mechanical fixture for welding with application number CN216966817U, the left side of the right movable slide is connected to a right clamping plate, the left side of the right clamping plate is connected to a right clamping joint, a plug-in slide rail is provided at the connection between the right clamping joint and the right clamping plate, a left clamping joint is provided on the left side of the right clamping joint, a left clamping plate is provided on the left side of the left clamping joint, a left sliding plate is connected to the left side of the left clamping plate, the left sliding plate is connected to the left column, a sliding screw is plugged at the lower position of the right movable slide, and the left and right ends of the sliding screw are respectively connected to the left column and the right column, and there are two plug-in slide rails, and the two plug-in slide rails are respectively provided at the connection between the left clamping joint and the left clamping plate and the right clamping plate. The connection between the left and right clamping joints is such that when in use, clamping joints of different shapes can be replaced for different welding workpieces. If a workpiece with a square cross-section is to be welded, the clamping joint can be replaced with a flat structure on the outer surface. If the welding workpiece is an arc-shaped structure, the clamping joint can be replaced with an arc-shaped structure on the outer surface. It is very convenient to replace. You only need to slide the left and right clamping joints up and down relative to the clamping plate using the plug-in slide rails to separate and insert them. The operation is convenient, and the fixture is suitable for clamping work of welding workpieces of different shapes. Different clamping joints for different workpieces are more firmly clamped and will not shake, so that the welding quality is higher. However, when it is in use, debris or welding slag falls on the surface thread of the clamping thread column. As the clamping thread column is twisted, the clamping thread column is worn, which has an adverse effect on the use of the clamping thread column and affects the service life of the clamping thread column.
