Description

Technical Field

[0001] The utility model relates to the technical field of lathe processing, in particular to a clamp device for controlling the concentricity of lathe processing. Background Art

[0002] CNC lathes are one of the most widely used CNC machine tools. They are primarily used for machining internal and external cylindrical surfaces of shafts and disks, internal and external conical surfaces of arbitrary taper angles, complex internal and external curved surfaces of rotation, and cylindrical and conical threads. They can also perform grooving, drilling, reaming, reaming, and boring. CNC machine tools automatically process parts according to pre-programmed machining programs. Fixtures are essential components for controlling lathe machining. When machining parts, fixtures must be used to position and clamp the parts before machining to ensure that the surface meets the technical requirements for size, geometry, and relative positional accuracy with other surfaces as specified in the drawings. This ensures machining accuracy and maintains product quality.

[0003] However, in actual operation, it is inconvenient to rotate the workpiece after it is fixed. Manual rotation is required, which is labor-intensive, time-consuming and labor-intensive. Therefore, we propose a clamping device for controlling the concentricity of lathe processing to solve the above problem. Utility Model Content

[0011] Further preferably, the front ends of the two screw rods on the front side extend outside the vertical plate and are fixedly connected to a crank.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: when the crank of the present invention is shaken, the crank drives the corresponding two screws to rotate synchronously, and the threads of the corresponding two screws are set in opposite directions, thereby driving the corresponding two rectangular blocks to move in the direction of approaching each other, and the rectangular blocks slide on the outside of the slide rail, and the rectangular blocks drive the clamping blocks to clamp and fix the workpiece body.
