Embodiment Construction

[0031] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] figure 1 Shown is a schematic diagram of the support device of the fixture used to support the workpiece in an embodiment of the present invention. Such as figure 1 As shown, the clamp of the present invention includes a clamp body 200 and a supporting device 300 . Wherein, the supporting device 300 can be installed inside the clamp body 200 to support the workpiece 400 .

[0033] Specifically, such as figure 2 As shown, the clip body 200 is formed with a first channel 210 and a second channel 220 . The first channel 210 extends along the first directi...

Abstract

Provided is a supporting device used in a clamp body. The supporting device comprises a mandril, a supporting nail, a lead screw, a thread bushing, a push rod and a pin. The mandril and the supporting nail are arranged on the clamp body along a first direction. The supporting nail is arranged on the mandril. A locating groove is formed in the mandril. The lead screw, the thread bushing, the push rod and the pin are arranged in the clamp body along a second direction. The lead screw is arranged in the thread bushing. The push rod is arranged between the lead screw and the pin. The lead screw can rotate relative to the thread bushing and pushes the pin to move towards the locating groove of the mandril through the push rod. A clamp using the inner supporting device is further provided.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a clamp and its internal support device. Background technique [0002] In the rough machining process of the parts, in order to avoid the machining of the workpiece due to the large cutting force of the tool and the long length of the processed parts (such as the engine cylinder head, the front and rear axle housings of the car) or the processing of thin-walled parts (such as the transmission housing, oil The deformation caused by bottom shell, etc.) often adds a support mechanism to the processing fixture to reduce the deflection deformation of the workpiece during processing and ensure the processing accuracy of the workpiece. [0003] The commonly used solution now is to add an auxiliary support mechanism on the workpiece support surface. For manual fixtures, after the workpiece enters the fixture and falls on the support plane, after adjusting the support force and height...
