Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a clamping table capable of preventing jamming. Background Art

[0002] Clamping devices play a crucial role in machining. They hold the workpiece in place, preventing it from shifting or moving during machining, thereby ensuring precision and stability. This securing function is crucial for improving product quality and reducing scrap. For example, in milling, a clamping device secures the workpiece to the workbench. By adjusting the clamping force, the workpiece's position and movement can be controlled during machining.

[0003] When the clamping device clamps the workpiece, the processed iron chips will fall onto the bidirectional threaded rod. If they are not cleaned, the clamping plate may get stuck during the movement. Generally, the operator has to clean it manually, which not only increases the workload of the operator, but also wastes time and effort. Utility Model Content

[0022] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a clamping table that can prevent jamming, including a workbench 1, a two-way threaded rod 2 is rotatably installed in the groove of the workbench 1, which can drive two clamping plates 4 to move simultaneously to the middle or to both sides, a turntable 3 is fixedly installed on the right side of the two-way threaded rod 2, which can make the two-way threaded rod 2 rotate, and the outer wall of the two-way threaded rod 2 is threadedly connected with the clamping plate 4, which can clamp the workpiece, and the bottom of the clamping plate 4 is slidably installed in the groove of the workbench 1, and a cleaning mechanism 5 is provided on the top of the workbench 1, which can clean the outer wall of the two-way threaded rod 2, and a pushing mechanism 6 is provided on the top of the workbench 1, which can enable a brush to clean, and two groups of cleaning mechanisms 5 and pushing mechanisms 6 are provided, and are symmetrical with the central symmetry axis of the side of the workbench 1, and are symmetrically distributed on the left and right sides of the workbench 1, so that the two-way threaded rods 2 on both sides can be cleaned.

[0023] Specifically, the cleaning mechanism 5 includes: a hollow block 51, a movable spring 52, a cleaning ring 53, an L-shaped rod 54, a rotating rod 55, a torsion spring 56, a fixed rod 57, a cleaning plate 58, and a cleaning groove 59. The left side of the hollow block 51 is fixedly installed on the right side of the clamping plate 4 to facilitate the installation of the movable spring 52. The movable spring 52 is fixedly installed in the groove of the hollow block 51, which can reset the cleaning ring 53 after being squeezed. The cleaning ring 53 is fixedly installed on the end of the movable spring 52 away from the hollow block 51 to facilitate the installation of a brush to clean the bidirectional threaded rod 2. The outer wall of the cleaning ring 53 is slidably installed in the groove of the hollow block 51. The bottom of the L-shaped rod 54 is fixedly mounted on the outer wall of the cleaning ring 53, facilitating the movement of the cleaning ring 53. A rotating rod 55 is rotatably mounted on the top of the workbench 1, facilitating the installation of a fixing rod 57. A torsion spring 56 is fixedly mounted on the top of the workbench 1, enabling the rotating rod 55 to return to its original position after rotation. The end of the torsion spring 56, away from the workbench 1, is fixedly mounted on the outer wall of the rotating rod 55. A fixing rod 57 is fixedly mounted on the bottom of the rotating rod 55, which can be squeezed by the L-shaped rod 54, causing the cleaning ring 53 to move and drive the rotating rod 55 to rotate. The rotating rod 55, torsion spring 56, and fixing rod 57 are arranged in a circular array around the top of the workbench 1. This allows the cleaning ring 53 to move several times, resulting in a better cleaning effect. A cleaning plate 58 is fixedly mounted on the front of the clamping plate 4, enabling the cleaned iron filings to be pushed into the cleaning groove 59. A cleaning groove 59 is provided at the bottom of the workbench 1 groove to facilitate the removal of iron filings.

[0024] Specifically, the pushing mechanism 6 includes: a circular groove 61, a return spring 62, an extrusion ring 63, and an extrusion rod 64. A circular groove 61 is provided on the side of the clamping plate 4 to facilitate the extrusion rod 64 to push the extrusion ring 63. A return spring 62 is fixedly installed in the groove of the hollow block 51, which can reset the extrusion ring 63 after moving. The extrusion ring 63 is fixedly installed on the end of the return spring 62 away from the hollow block 51, which can clean the brush on the inner wall of the cleaning ring 53. An extrusion rod 64 is fixedly installed on the right side of the groove of the workbench 1. Two groups of extrusion rods 64 are provided, and are symmetrical with the central symmetry axis of the side of the bidirectional threaded rod 2, and are symmetrically distributed on the left and right sides of the bidirectional threaded rod 2, which can better push the extrusion ring 63 to move.

[0025] Working principle: When the turntable 3 is rotated to rotate the bidirectional threaded rod 2, the clamping plate 4 will move toward the middle, so that the hollow block 51 will drive the cleaning ring 53 to move. During the movement, the L-shaped rod 54 will squeeze the fixed rod 57, so that the L-shaped rod 54 drives the cleaning ring 53 to move in the groove of the hollow block 51, and the moving spring 52 is compressed. When it moves to the end, the L-shaped rod 54 will cause the fixed rod 57 to drive the rotating rod 55 to rotate, and the torsion spring 56 is twisted. Until the L-shaped rod 54 moves past, the torsion spring 56 drives the rotating rod 55 to reset, and the moving spring 52 drives the cleaning ring 53 and the L-shaped rod 54 to reset, so that the cleaning ring 53 can move back and forth, so that the brush on the inner wall of the cleaning ring 53 can clean the outer wall of the bidirectional threaded rod 2, and the cleaned iron filings will be pushed into the cleaning groove 59 by the cleaning plate 58 to prevent iron filings from remaining on the outer wall of the bidirectional threaded rod 2 and getting stuck.

[0026] When the clamping plate 4 is fully opened, the extrusion rod 64 will enter the circular groove 61, pushing the extrusion ring 63 toward the brush at the bottom of the cleaning ring 53, and the return spring 62 will be stretched, so that the extrusion ring 63 cleans the brush on the inner wall of the cleaning ring 53. When the clamping plate 4 moves toward the middle, the extrusion rod 64 will disengage from the circular groove 61, and the return spring 62 will drive the extrusion ring 63 to reset, preventing iron filings from remaining on the brush of the cleaning ring 53, causing the outer wall of the bidirectional threaded rod 2 to be scratched during the next cleaning.

[0027] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
