Description

Technical Field

[0001] This utility model relates to the field of clamping and fixing equipment technology, specifically a clamping device for processing stainless steel plates. Background Technology

[0002] Stainless steel sheet processing involves a series of processes such as forming, cutting, and surface treatment of stainless steel sheets to process raw sheets into parts or finished products that meet specific size, shape, or performance requirements.

[0003] When processing stainless steel sheets, such as during cutting, milling, and bending, they are subject to external impacts. If not clamped and fixed, they are prone to slippage, displacement, or vibration. Existing clamping and fixing methods generally involve vertically movable clamping plates on both sides of the processing table. The stainless steel sheets on the processing table are fixed by moving the clamping plates up and down. When placing or replacing stainless steel sheets on the processing table, the position of the clamping plates that fix the sheets needs to be adjusted, and then reset and fixed after placement. To improve the clamping and fixing effect of the sheets, multiple clamping plates are usually set for multi-point fixing. Existing clamping devices cannot adjust the position of the clamping plates synchronously. Adjusting them individually is not only cumbersome but also has low clamping efficiency. Based on this, a clamping device for processing stainless steel sheets is proposed. Utility Model Content

[0004] This utility model provides a clamping device for processing stainless steel plates, which solves the problem mentioned in the above technical background that the existing clamping devices cannot synchronously adjust the position of the clamping plate. Adjusting them individually is not only cumbersome to operate, but also has low clamping efficiency.

[0005] A clamping device for processing stainless steel sheets includes a processing table, with movable boxes fixedly arranged on both sides of the processing table. A movable block is slidably connected inside the movable box. A displacement mechanism for moving the movable block is provided inside the processing table. A threaded cylinder is rotatably connected to the top of the movable block. A drive mechanism for rotating the threaded cylinder is provided inside the movable box. A first threaded rod is threadedly connected inside the threaded cylinder. A top plate is fixedly connected to the top of the first threaded rod on the same side. A clamping plate is movably connected below the top plate.

[0006] Preferably, the displacement mechanism includes two rotating slots formed in the processing table, a bidirectional lead screw is rotatably connected in the rotating slots, movable blocks are threaded to both sides of the bidirectional lead screw, a moving rod is fixedly connected to the movable block, and the two ends of the moving rod extend through into the moving box and are fixedly connected to the side wall of the moving block.

[0007] Preferably, the processing table has a connecting groove inside with both ends connected to the rotating groove. A dual-axis motor is fixedly installed in the middle of the connecting groove. The output shaft of the dual-axis motor is fixedly connected to a rotating rod. A first bevel gear is fixedly sleeved at the end of the rotating rod. The first bevel gear is meshed with a second bevel gear. The second bevel gear is fixedly sleeved on a bidirectional lead screw.

[0008] Preferably, the driving mechanism includes a gear fixedly sleeved below the threaded cylinder, and a rack is fixedly provided on one inner wall of the movable box, with the gear meshing with the rack.

[0009] Preferably, a second threaded rod is threadedly connected to the top plate, and the bottom of the second threaded rod is rotatably connected to the top of the clamping plate.

[0010] Preferably, limiting rods are fixedly provided on both sides of the top of the clamping plate, and the limiting rods are slidably connected to the top plate.

[0011] Preferably, a silicone pad is fixedly provided at the bottom of the clamping plate.

[0012] The beneficial effects of this utility model are:

[0013] (1) This utility model uses a dual-axis motor to drive the rotating rods on both sides and the first bevel gear to rotate. The first bevel gear on both sides meshes with the second bevel gear to rotate, thereby driving the bidirectional lead screw on both sides to rotate synchronously. This causes the movable blocks on both sides of the bidirectional lead screw to move in opposite directions. The moving rod fixedly connected to the movable block drives the movable block to move in opposite directions in the moving box. This causes the threaded cylinder above the movable block and the first threaded rod to drive the top plate and the clamping plate below it to move to both sides, and synchronously adjust the position of the clamping plate above the processing table.

[0014] (2) In this utility model, while the threaded cylinder moves, the gear below the threaded cylinder continuously meshes with the rack, so that the threaded cylinder rotates continuously while moving. The rotation of the threaded cylinder causes the first threaded rod to drive the top plate to move up and down, so that the clamping plate below the top plate moves down while moving towards the processing table to fix the stainless steel plate. Conversely, the clamping plate moves up while moving outward to release the fixation of the stainless steel plate, thereby achieving the effect of synchronous adjustment of the left and right and up and down positions of the clamping plate, simplifying the clamping and fixing operation, and improving the clamping efficiency of the stainless steel plate.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] like Figure 1-4 As shown, a clamping device for processing stainless steel sheets includes a processing table 1. Movable boxes 2 are fixedly provided on both sides of the processing table 1. Movable blocks 3 are slidably connected inside the movable boxes 2. The processing table 1 is provided with a displacement mechanism for moving the movable blocks 3. A threaded cylinder 4 is rotatably connected to the top of the movable blocks 3. A drive mechanism for rotating the threaded cylinder 4 is provided inside the movable boxes 2. A first threaded rod 5 is threadedly connected inside the threaded cylinder 4. A top plate 6 is fixedly connected to the top of the first threaded rod 5 on the same side. A clamping plate 7 is movably connected to the bottom of the top plate 6.

[0022] The displacement mechanism includes two rotating slots 8 formed within the processing table 1. A bidirectional lead screw 9 is rotatably connected within each rotating slot 8. Movable blocks 10 are threadedly connected to both sides of the bidirectional lead screw 9. A moving rod 11 is fixedly connected to each movable block 10. Both ends of the moving rod 11 extend through into the moving box 2 and are fixedly connected to the side wall of the moving block 3. The side wall of the processing table 1 has through holes for the moving rod 11 to pass through. The rotation of the bidirectional lead screw 9 causes the movable blocks 10 on both sides of the bidirectional lead screw 9 to move in opposite directions. This causes the moving rod 11, which is fixedly connected to the movable blocks 10, to drive the moving blocks 3 on both sides to move in opposite directions within the moving box 2. The first threaded rod 5 at the top of the moving block 3 and the clamping plate 7 below the top plate 6 move to both sides, adjusting the position of the clamping plate 7 above the processing table 1.

[0023] The processing table 1 has a connecting groove 12 with both ends connected to the rotating groove 8. A dual-axis motor 13 is fixedly installed in the middle of the connecting groove 12. The output shaft of the dual-axis motor 13 is fixedly connected to a rotating rod 14. A first bevel gear 15 is fixedly sleeved at the end of the rotating rod 14. The first bevel gear 15 is meshed with a second bevel gear 16. The second bevel gear 16 is fixedly sleeved on a bidirectional lead screw 9. The directions of the first bevel gears 15 on the rotating rods 14 on both sides and the directions of the second bevel gears 16 in the two rotating grooves 8 on the bidirectional lead screw 9 are opposite. The dual-axis motor 13 drives the rotating rods 14 and the first bevel gears 15 on both sides to rotate in the same direction and at the same speed. The first bevel gears 15 on both sides mesh with the second bevel gears 16 and rotate in the same direction, thereby driving the bidirectional lead screws 9 on both sides to rotate synchronously, so as to achieve the purpose of synchronous movement of the threaded cylinders 4 on both sides of the processing table 1.

[0024] The driving mechanism includes a gear 17 fixedly sleeved below the threaded cylinder 4, and a rack 18 fixedly installed on one inner wall of the movable box 2. The gear 17 and rack 18 are meshed and connected. As the threaded cylinder 4 moves outward, the gear 17 below the threaded cylinder 4 continuously meshes with the rack 18, causing the threaded cylinder 4 to rotate continuously while moving. The rotation of the threaded cylinder 4 causes the first threaded rod 5 to drive the top plate 6 to move upward, causing the clamping plate 7 below the top plate 6 to move upward and release the fixation on the stainless steel plate. The clamping plate 7 moves outward to both sides of the processing table 1, which facilitates the replacement and placement of the stainless steel plate to be processed. After replacement, the threaded cylinders 4 on both sides move towards the center of the processing table 1, causing the clamping plate 7 below the top plate 6 to move downward and fix the stainless steel plate, achieving the effect of synchronous adjustment of the left and right and up and down positions of the clamping plate 7. The clamping and fixing operation is simple and improves the clamping efficiency of the stainless steel plate.

[0025] The top plate 6 is threaded with a second threaded rod 19. The bottom of the second threaded rod 19 is rotatably connected to the top of the clamping plate 7. By rotating the second threaded rod 19, the clamping plate 7 is moved up and down, and the distance between the clamping plate 7 and the processing table 1 is adjusted. This method is suitable for clamping and fixing plates of different thicknesses.

[0026] Limiting rods 20 are fixedly provided on both sides of the top of the clamping plate 7. The limiting rods 20 are slidably connected to the top plate 6. The movement trajectory of the clamping plate 7 is restricted by the limiting rods 20, so that the clamping plate 7 moves only up and down in the vertical direction with the rotation of the second threaded rod 19, and does not rotate with the rotation of the second threaded rod 19. This avoids the friction between the rotation of the clamping plate 7 and the surface of the stainless steel plate when clamping downwards, which may cause damage to the plate.

[0027] The bottom of the clamping plate 7 is fixed with a silicone pad 21, which can also be set as other buffer materials according to actual needs. The thickness of the silicone pad 21 is set to 2-5mm. The silicone pad is elastic and can change the clamping force from point contact to surface contact, disperse the clamping pressure, and avoid excessive local stress, which could damage the surface of the stainless steel plate.

[0028] A pressure sensor is installed at the bottom of the clamping plate 7. When the clamping plate 7 clamps and fixes the plate below, the controller controls the dual-axis motor 13 to stop running when the clamping pressure reaches the set value.

[0029] In use, the stainless steel sheet to be processed is placed on the processing table 1. According to the thickness of the sheet, the second threaded rod 19 is rotated to drive the clamping plate 7 to move up and down, adjusting the distance between the clamping plate 7 and the processing table 1 so that the height of the clamping plate 7 can stably clamp and fix the sheet. The dual-axis motor 13 is started to drive the rotating rods 14 on both sides and the first bevel gear 15 to rotate. The first bevel gear 15 on both sides meshes with the second bevel gear 16 to rotate, thereby driving the bidirectional lead screws 9 on both sides to rotate synchronously. The movable blocks 10 and the moving rods 11 on both sides of the bidirectional lead screws drive the moving blocks 3 and the threaded cylinder 4 to move towards the worktable 1. At the same time, the gear 17 below the threaded cylinder 4 continuously meshes with the rack 18, so that the threaded cylinder 4 rotates continuously while moving. The rotation of the threaded cylinder 4 causes the first threaded rod 5 to drive the top plate 6 to move downward, so that the clamping plate 7 below the top plate 6 moves downward while moving towards the processing table 1 to fix the stainless steel sheet. The two are carried out synchronously, simplifying the clamping and fixing operation and improving the clamping efficiency of the stainless steel sheet.

[0030] It should be noted that, for the present invention as fully described, there may be various variations and modifications, and it is not limited to the specific embodiments described above. In summary, the scope of protection of this utility model should include those variations, substitutions, and modifications that are obvious to those skilled in the art, and the appended claims shall prevail.
