Description

TECHNICAL FIELD

[0001] The utility model relates to clamping technical field, concretely is a kind of metal parts machining clamping device. BACKGROUND

[0002] In the process of machining metal parts, metal parts or raw materials are usually clamped and positioned by clamping devices, so that metal parts or raw materials do not shake during machining, thereby improving the stability and accuracy of metal part machining. However, the existing metal part machining clamping device still has some defects in use.

[0003] For example, the clamping device for metal part machining disclosed in application No. CN202220975445.1 includes a turntable, a machining platform, a pull ring, a clamping plate, and a bottom plate. The turntable is rotated to drive the first bevel gear at the bottom end of the shaft to rotate, further driving the threaded rod to rotate, and further moving the clamping plate on the threaded rod towards the side of the metal part, thereby achieving extrusion on one side of the metal part. The first clamping device is provided to achieve extrusion on the other side of the metal part, thereby achieving clamping and positioning of the metal part. The clamping operation is convenient, and the operator can conveniently process the metal part. When the machining platform needs to be rotated, the pull ring is pulled to move the clamping plate away from the gear, and the machining platform is further rotated to the appropriate position, facilitating the operator to process the metal part. After rotating to the appropriate position, the pull ring is released, and the clamping plate moves and clamps into the gear under the action of the spring force, thereby limiting the position of the machining platform. In actual use, the threaded rod needs to be rotated repeatedly to achieve clamping and relaxation during multiple clamping of metal parts of the same specification, which reduces the clamping efficiency.

[0004] Therefore, we propose a metal part machining clamping device to solve the problems mentioned above. UTILITY MODEL CONTENTS

[0015] With the above structure, the position of the adjusting and positioning mechanism on both sides of the telescopic clamping mechanism can be adjusted, so that the distance between the two can be adapted to the size of the clamped workpiece, thereby improving the clamping adaptability of the metal part machining clamping device.
