FIG. 1 is a schematic structural view of an integrated tooling fixture according to an embodiment of the present invention;
fig. 2 is the utility model discloses embodiment integral type frock clamp cross-sectional view.
Detailed Description
In order to make the objects, contents and advantages of the present invention clearer, the following description will make a detailed description of embodiments of the present invention with reference to the accompanying drawings and examples.
The embodiment provides an integrated tool clamp, which is structurally shown in fig. 1 and 2 and mainly comprises a base 1, a clamping clamp and a locking device.
The upper and lower surfaces of the base 1 are parallel and have high requirements on flatness. The clamping pincers comprise a lower pincers rod 2, an upper pincers rod 3, a connecting pin 4 and an arc-shaped elastic sheet 5. The bottom of the lower nipper rod 2 is fixedly connected with the base 1, and the fixed end of the upper nipper rod 3 is connected with the fixed end of the lower nipper rod 2 through the connecting pin 4, so that the relative rotation between the upper nipper rod and the lower nipper rod is realized. An arc-shaped elastic sheet 5 is arranged between the lower clamp rod 2 and the upper clamp rod 3 and is used for supporting the upper clamp rod 3 and realizing the separation of the jaws of the upper clamp rod and the lower clamp rod.
The locking device comprises a locking bolt 6, a washer 7 and an adjusting nut 8. The head of the locking bolt 6 is fixedly connected with the lower clamp rod 2, and the rod part sequentially penetrates through the lower clamp rod 2, the upper clamp rod 3 and the gasket 7 from bottom to top and then is in threaded connection with the adjusting nut 8, so that the distance between the upper jaw and the lower jaw is adjusted.
When the clamp is used for clamping, the base 1 is fixed on a machine tool workbench, a workpiece is arranged between the upper jaw and the lower jaw, and the adjusting nut 7 is rotated to compress the workpiece.
The clamp adopts an integrated structure, so that the clamping and the disassembly of a workpiece are convenient, and the clamping process is simplified; the upper jaw and the lower jaw of the clamping pincers are two larger planes, so that the clamp and a workpiece can be ensured to have a large enough contact area, and the workpiece is prevented from being clamped and damaged by stress concentration; the plane of the lower jaw is parallel to the plane of the base and is a horizontal plane, so that the stability of workpiece clamping can be ensured; the locking device utilizes the threads to adjust the clamping force between the upper jaw and the lower jaw, and can ensure the firmness of workpiece clamping.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
