Description

Technical Field

[0001] The present invention relates to the technical field related to mechanical processing, and in particular to a fast clamping mechanical processing table. Background Art

[0002] Machining is the process of changing the dimensions or performance of a workpiece through mechanical means. Machining can be categorized into cutting and press working, depending on the method used. To ensure smooth machining of the workpiece, a machining table is required to place and support the workpiece.

[0003] In order to ensure that the workpiece can be machined stably and safely on the machining table, a corresponding clamping structure needs to be set up on the machining table to clamp and fix the workpiece. Most of the existing clamping structures adjust the movement of the clamping parts by rotating the thread, and then complete the clamping and fixing by the thread self-locking function. However, when the workpiece is small and the spacing between the corresponding clamping parts is too large, in order to successfully complete the clamping work, the user needs to rotate the threaded parts for a long time to make the clamping parts close to each other, and then complete the clamping and fixing work of the small-volume workpiece. Such operation is time-consuming and labor-intensive, and is not conducive to the user's fast work.

[0004] Therefore, we propose a fast clamping machining table to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems existing in the prior art and to propose a fast clamping type machining table.

[0009] Preferably, the threaded squares of the two threaded columns are arranged in opposite directions, a support seat is fixedly connected in the sliding groove, the support seat is arranged between the two rotating columns, a rotating hole is provided on the support seat, a square rod is rotatably connected in the rotating hole, an auxiliary column is fixedly connected on one side wall of the two rotating columns close to the support seat, a square groove is provided on one side wall of the two auxiliary columns close to the square rod, and both ends of the square rod are respectively slidably connected in the two square grooves.

[0010] Preferably, threaded openings are provided in the two threaded columns, and threaded rods are threadedly connected in the two threaded openings. The two threaded rods are respectively set through the two rotating columns, and the ends of the two threaded rods close to each other are fixedly connected to auxiliary rods. The ends of the multiple working columns close to the working tubes are fixedly connected to auxiliary blocks, and the multiple auxiliary blocks are respectively set through the two working tubes.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] When the present invention is working, the two clamping plates can be directly pushed to approach the workpiece at the center position first. The two clamping plates will drive the two sliding seats to slide in the sliding grooves during the movement. While the sliding seat is moving, the conical setting of the working column and the setting of the working spring can be used to allow the working column to enter the through hole without affecting the movement of the sliding seat. Then the user can rotate the threaded column so that the threaded column can push the rotating column while rotating in the threaded hole, and then the baffle on the working column can push the sliding seat, and then push the two clamping plates that have moved to the specified position to continue to approach each other and complete the clamping and fixing of the workpiece. In this way, the problem of rotating the threaded column for a long time to move the clamping plates is avoided, which greatly facilitates the user to work quickly. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-3, a quick clamping machining table includes a workbench 1, a sliding groove 2 is provided on the upper end surface of the workbench 1, and two symmetrically arranged clamping structures are provided in the sliding groove 2, the clamping structure includes a sliding seat 3 slidably connected to the sliding groove 2, a threaded hole 4 is provided on one side wall of the sliding groove 2, a threaded column 5 is threadedly connected to the threaded hole 4, and a rotating column 6 is fixedly connected to one end of the threaded column 5 near the sliding groove 2, and the rotating column 6 passes through the sliding seat 3. The threaded squares of the two threaded columns 5 are oppositely arranged, and a support seat 14 is fixedly connected in the sliding groove 2. The support seat 14 is arranged between the two rotating columns 6, and a rotating hole 15 is provided on the support seat 14. A square rod 16 is rotatably connected in the rotating hole 15, and the two rotating columns 6 are fixedly connected on one side wall near the support seat 14. Auxiliary column 17, two auxiliary columns 17 are provided with square grooves 18 on one side wall close to the square rod 16, and the two ends of the square rod 16 are respectively slidably connected in the two square grooves 18. The cooperation of the square grooves 18 and the square rod 16 makes it possible to smoothly drive the other auxiliary column 17 and the rotating column 6 to rotate when one of the rotating columns 6 drives the auxiliary column 17 to rotate, so that the user can control the rotation of the two threaded columns 5 at the same time and complete the movement work. At the same time, this arrangement makes it possible for the movement of the auxiliary column 17 to not interfere with the square rod 16. A clamping plate 28 is fixedly connected to the sliding seat 3, and a protective pad 24 is provided on the side wall where the two clamping plates 28 are close to each other. The setting of the protective pad 24 makes the clamping work of the workpiece safer, and the side where the two clamping plates 28 are far away from each other The wall is fixedly connected with a handle 25. The setting of the handle 25 makes it convenient for the user to directly push or pull the clamping plate 28 to move. The direct movement of the clamping plate 28 avoids the user having to rotate the threaded column 5 for a long time to complete the movement of the clamping plate 28, which greatly facilitates the user to quickly perform clamping work. A working chamber 7 is provided in the rotating column 6, and a working tube 8 is fixedly connected in the working chamber 7. A plurality of equally spaced clamping structures are provided on the side wall of the working chamber 7. The clamping structure includes a through hole 9 provided on the inner wall of the working chamber 7, and a working column 10 is slidably connected in the through hole 9. The end of the working column 10 away from the working tube 8 is tapered. Such a tapered setting allows the user to push the working column 10 into the through hole 9 when pushing the clamping plate 28 to move directly. The through-hole 9 allows the movement to proceed without interference. The end of the working column 10 away from the working tube 8 is fixedly connected to a baffle 11. With the help of the baffle 11, the working column 10 can push the sliding seat 3 when it moves toward the center position as the rotating column 6, and then the sliding seat 3 can push the clamping plate 28 to complete the clamping and fixing work. The baffle 11 is set away from the threaded column 5. A working spring 12 is fixedly connected to the side wall of the working column 10 close to the working tube 8. The end of the working spring 12 away from the working column 10 is fixedly connected to the outer wall of the working tube 8. A limiting plate 13 is fixedly connected to the outer wall of the working column 10. The limiting plate 13 is set close to the working spring 12. Threaded openings 19 are provided in the two threaded columns 5, and threaded rods 20 are threadedly connected in the two threaded openings 19.Two threaded rods 20 are respectively set through the two rotating columns 6. The ends of the two threaded rods 20 close to each other are fixedly connected to auxiliary rods 21. The ends of multiple working columns 10 close to the working tube 8 are fixedly connected to auxiliary blocks 22. Multiple auxiliary blocks 22 are respectively set through the two working tubes 8. Multiple auxiliary blocks 22 are fixedly connected to pull ropes 23. Multiple pull ropes 23 are respectively fixedly connected to the two auxiliary rods 21. This arrangement allows the user to rotate and move the threaded rods 20 in the threaded opening 19, driving the auxiliary rods 21 to pull the pull ropes 23 and the auxiliary blocks 22, thereby allowing the working column 10 and the baffle 11 to enter the through hole 9 without affecting the resetting work of the sliding seat 3 and the clamping plate 28. The two threaded columns 5 are fixedly connected to a swivel 26, and the two threaded rods 20 are fixedly connected to a turntable 27. This arrangement makes it convenient for the user to rotate the threaded column 5 and the threaded rod 20 separately.

[0021] When the workpiece is in use, the workpiece is first placed on the workbench 1, and then the two clamping plates 28 can be pushed close to each other by the handle 25, and then the two clamping plates 28 are moved to a position close to the workpiece. At this time, the two clamping plates 28 are not fixed, and naturally the work of clamping and fixing the workpiece is not completed. During the movement of the clamping plates 28, the corresponding sliding seat 3 is driven to slide in the sliding groove 2, and the sliding seat 3 slides on the rotating column 6. Since one end of the working column 10 is tapered, the sliding seat 3 can push the working column 10 to squeeze the working spring 12 into the through hole 9 during the movement toward the center position, so that the movement of the sliding seat 3 is not affected. Then the user can control the rotation of the threaded column 5 and the rotating column 6 at one end by the rotating ring 26. Since the rotating column 6 and the auxiliary column 17 are fixedly connected and the square groove 18 and the square rod 16 are slidably connected, the rotating column 6 and the threaded column 5 at the other end will also rotate in the same direction. At this time, since the threads of the two threaded columns 5 are set in opposite directions, the two threaded columns 5 can push the two rotating columns 6 to approach each other.

[0022] Since the baffle 11 is fixedly connected to the side wall of the working column 10 near the center position, when the working column 10 moves toward the center position with the rotating column 6, the sliding seat 3 can be pushed by the baffle 11, and then the two clamping plates 28 can be pushed to continue to approach each other, and then the two clamping plates 28 can squeeze and clamp the workpiece on the workbench 1. The clamping plates 28 will also complete the stable clamping and fixing work with the help of the threaded self-locking function of the threaded hole 4 and the threaded column 5. When this device continues to fix the work, the longer distance of the clamping plate 28 close to the workpiece is achieved by directly pushing the clamping plate 28 to move, rather than by rotating the threaded column 5 for a long time. To complete the work, it greatly saves time and the user's energy, allowing the user to quickly complete the clamping work. If the clamping plate 28 needs to be reset, the threaded rod 20 can be driven to rotate by the turntable 27, and then the threaded rod 20 can drive the auxiliary rod 21 to move. When the auxiliary rod 21 moves, multiple auxiliary blocks 22 can be pulled by multiple pull ropes 23, and then the working column 10 can squeeze the working spring 12 and retract it into the through hole 9. The baffle 11 will also be retracted into the through hole 9 along with the working column 10. In this way, the sliding seat 3 can smoothly slide and reset in the sliding groove 2, and then drive the clamping plate 28 to complete the reset work.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
