When clamping a flange with a chuck structure, it is clamped by clamping blocks installed inside the positioning holes. The disassembly and assembly of the clamping blocks are relatively cumbersome, and it is inconvenient to adjust when clamping different flanges. Content of the Utility Model

[0004] The purpose of the utility model is to provide a clamping device for flange processing to solve the problems of relatively cumbersome disassembly and assembly of the clamping blocks and inconvenient adjustment when clamping different flanges as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions: including: a chuck frame, the outer wall of the bottom end of the chuck frame is fixedly connected to one side of a mounting block, the inner wall of the chuck frame is fixedly connected to the outer wall of a positioning mechanism, the positioning mechanism includes a positioning plate, a sliding groove, a positioning groove, a return spring, a blocking plate and a clamping groove, the outer wall of the positioning mechanism is movably connected to the inner wall of a clamping component, the clamping component includes a clamping block, a movable groove, an extending sliding groove, a stable groove and a sliding block, and the inner wall of the clamping component is movably connected to the outer wall of a disassembly and assembly mechanism, the disassembly and assembly mechanism includes a moving rod, an extrusion groove, a connecting spring, a connecting plate, an extrusion rod and a clamping block.

[0006] As a preferred embodiment, the outer wall of the positioning plate is fixedly connected to the inside of the chuck frame, and sliding grooves are opened on both sides of the positioning plate, and a plurality of groups of positioning grooves are uniformly opened inside the positioning plate.

[0007] As a preferred embodiment, the inner bottom wall of the positioning groove is fixedly connected to the bottom end of the return spring, and the top end of the return spring is fixedly connected to the bottom end of the blocking plate, and clamping grooves are opened on both sides of the inner wall of the positioning groove.

[0008] As a preferred embodiment, a movable groove is opened inside the clamping block, and extending sliding grooves are opened on both sides of the inner wall of the movable groove, a stable groove is opened at the bottom of the movable groove, and both sides of the inner wall of the stable groove are fixedly connected to one side of the sliding block.

[0009] As a preferred embodiment, the inner wall of the stabilizing groove is movably connected to the outer wall of the positioning plate, and the outer wall of the sliding block is movably connected to the inner wall of the sliding groove.

[0010] As a preferred embodiment, the inner wall of the movable groove is movably connected to the outer wall of the moving rod, and an extrusion groove is formed inside the moving rod. One end of a connecting spring is fixedly connected to the inner side wall of the extrusion groove, and the other end of the connecting spring is fixedly connected to one side of the connecting plate.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0013] 1. In the present utility model, when adjusting the position of the clamping block above the positioning plate, first press the extrusion rod to drive the connecting plate to extrude the connecting spring. As the connecting plate moves, the clamping block moves away from the inside of the clamping groove. While pressing the extrusion rod, move the extrusion rod upward, thereby driving the moving rod to move upward, so that the whole moving rod moves away from the inside of the positioning groove. When the moving rod moves, it drives the clamping block to move, thereby adjusting the position of the clamping block. When the clamping block reaches the clamping position, move the extrusion rod downward, thereby driving the extrusion rod to re-enter the position of a set of positioning grooves. Release the extrusion rod, and the connecting plate is driven to move by the reset of the connecting spring, thereby driving the clamping block to enter the inside of the clamping groove, thus stably clamping the clamping block again, facilitating the staff to adjust the position of the clamping block, and getting rid of the traditional way of reciprocating disassembly and assembly when adjusting the clamping block.

[0014] 2. In the present utility model, when the moving rod moves away from the inside of the positioning groove, the blocking plate is driven to reset by the reset of the return spring and blocks at the top of the positioning groove. Initially, the blocking plate blocks at the top of the positioning groove by the reset of the return spring, avoiding the chips generated during flange processing from entering the inside of the positioning groove. At the same time, as the blocking plate moves upward inside the positioning groove, it is convenient to clean the chips inside the positioning groove. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Specifically, the multi - group positioning grooves 303 facilitate the stabilization and limitation of the clamped block 401 after movement.

[0026] In one embodiment, the inner bottom wall of the positioning groove 303 is fixedly connected to the bottom end of the return spring 304, and the top end of the return spring 304 is fixedly connected to the bottom end of the blocking plate 305. Clamping grooves 306 are provided on both sides of the inner wall of the positioning groove 303.

[0027] Specifically, the return of the return spring 304 drives the blocking plate 305 to return and block at the top of the positioning groove 303.

[0028] In one embodiment, an activity groove 402 is provided inside the clamped block 401, and extending sliding grooves 403 are provided on both sides of the inner wall of the activity groove 402. A stabilizing groove 404 is provided at the bottom of the activity groove 402, and both sides of the inner wall of the stabilizing groove 404 are fixedly connected to one side of the sliding block 405.

[0029] Specifically, the clamped block 401 clamps and stabilizes the flange, and the activity groove 402 provides a space for the movement rod 501 to move and be stored.

[0030] In one embodiment, the inner wall of the stabilizing groove 404 is movably connected to the outer wall of the positioning plate 301, and the outer wall of the sliding block 405 is movably connected to the inner wall of the sliding groove 302.
