Description

Technical Field

[0001] The utility model belongs to the technical field of a clamp chuck, and more specifically, particularly relates to an anti-dropping device for a clamp chuck. Background Art

[0002] The chuck is a mechanical device used to clamp the workpiece on the machine tool. It is a machine tool accessory that uses the radial movement of the movable jaws evenly distributed on the chuck body to clamp and position the workpiece. The lathe chuck is mainly composed of the chassis, jaws, rotating plate, adjuster, and the outermost part is the base. From the appearance structure, it can be divided into: two-jaw, three-jaw, four-jaw and other types.

[0003] Based on the above, the inventors have discovered the following problems: when installing the card block on the current clamp chuck, it is usually replaced into the chuck and then fixed with bolts. When the chuck rotates at high speed, the bolts may loosen, causing the card block to disengage and fall off due to centrifugal force. When rotating at high speed, the falling of the card block poses a great safety hazard.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a clamp chuck anti-disengagement device is provided, in order to achieve a purpose with greater practical value. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a clamp chuck anti-dropping device to solve the problem that the clamping block on the existing chuck may fall off and cause a greater safety hazard.

[0006] The purpose and effect of the anti-dropping device for a clamp chuck of the utility model are achieved by the following specific technical means:

[0007] A clamp chuck anti-slipping device comprises a chuck body, a plurality of slide grooves are provided on the surface of the chuck body, a sliding block is installed in the slide groove, a slot is provided on the surface of the sliding block, a group of straight slots are installed in the slot, an arc groove is provided at the bottom of the straight slot, a limit block is installed in the arc block groove, a connecting block is provided on the surface of the limit block, the connecting block matches the slot, a clamping block is installed on the surface of the connecting block, a group of first threaded holes are provided on the surfaces of the clamping block and the moving block, and a first bolt is installed in the first threaded hole.

[0008] Furthermore, a square groove is provided on the surface of the chuck body, a square block is installed in the square groove, a support is installed on the surface of the square block, a second threaded hole is provided on the surface of the support, the second threaded hole passes through the square block and extends to the inside of the chuck body, and a second bolt is installed in the second threaded hole.

[0009] Furthermore, a rubber pad is installed on the surface of the block, and an anti-slip pattern is arranged on the surface of the rubber pad.

[0010] Furthermore, a mounting hole is provided on the surface of the chuck body.

[0011] Furthermore, the limit block matches the straight groove and the arc groove.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model cooperates with the use of a slide groove, a sliding block, an open groove, a straight groove, an arc groove, a limit block, a connecting block, a clamping block, a first threaded hole and a first bolt. When installing the clamping block, it is only necessary to align the limit block with the straight groove and then insert it. When the limit block moves to the bottom of the straight groove, the clamping block is rotated. The rotation of the clamping block will drive the connecting block to rotate. The rotation of the connecting block will drive the limit block to rotate, so that the limit block is screwed into the end of the arc groove. At this time, the first threaded hole on the clamping block is aligned with the threaded hole on the sliding block, and then the first bolt is inserted into the first threaded hole and tightened to complete the fixation. Through the above design, the clamping block can be quickly installed. At the same time, when the bolts of one of the clamping blocks are loose, the clamping block will not rotate out due to centrifugal force, thereby greatly improving safety.

[0014] Through the square groove, square groove, square block, support, second threaded hole and second bolt, when thinner parts need to be clamped, a support that matches the part can be selected, and then the square block on the support is inserted into the square groove, and then the second bolt is inserted into the second threaded hole and tightened to complete the fixation. Through the above design, when thinner parts are clamped, there is a support inside, thereby avoiding extrusion and deformation of the parts. BRIEF DESCRIPTION OF THE DRAWINGS
