Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, and specifically to a clamping device with good fit. Background Technology

[0002] Clamping devices are widely used equipment or tools in mechanical engineering to fix workpieces for processing, assembly or other operations. They apply pressure to hold the workpiece firmly in the desired position, ensuring that the workpiece will not move or slide during operation, thereby guaranteeing processing accuracy and safety.

[0003] Chinese Patent Publication No. CN220330666U discloses a clamping device. This patent controls a cylinder to drive the machine body to move longitudinally, which in turn moves the clamping components and the alloy part longitudinally, thereby adjusting the height of the alloy part. During the movement of the machine body, a guide rod provides guidance to prevent deviation, and a limiting block restricts the upward movement of the machine body to prevent excessive upward movement due to cylinder damage. This application allows for adjustment of the height of the alloy part after clamping, meeting various cutting requirements.

[0004] In existing technologies, the clamping plates are usually fixedly installed and cannot flexibly handle workpieces of different shapes and sizes, resulting in poor clamping effect. At the same time, excessive clamping force can easily cause scratches or indentations on the workpiece surface.

[0005] Based on this, the present invention designs a clamping device with good fit to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a clamping device with good fit.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A clamping device with good fit includes a connecting frame and fixing blocks. Two fixing blocks are fixedly installed at the top of the connecting frame. A clamping assembly is installed on the lower surface of the fixing blocks, and a disassembly assembly is installed on the outer surface of the clamping assembly. The clamping assembly includes a side plate fixedly installed on the outer surface of the connecting frame. A motor is fixedly connected to the side of the side plate. A double-acting lead screw is fixedly connected to the output shaft end of the motor through a coupling. Two sleeves are threadedly connected to the outer surface of the double-acting lead screw. The disassembly assembly is fixedly installed in the mounting grooves below the two sleeves. Mounting blocks are engaged inside the two mounting grooves, and a clamping plate is fixedly connected to the bottom of the mounting blocks.

[0009] Furthermore, a slide rail is installed at the bottom of the connecting frame, and a slider is slidably connected inside the slide rail, with the lower surface of the slider connected to the sleeve.

[0010] Furthermore, each of the mounting slots has two movable slots inside, and a spring is fixedly connected inside the two movable slots. One end of the spring is fixedly connected to a protrusion, and the other end of the spring is connected to the inside of the movable slot.

[0011] Furthermore, the outer surface of the mounting block has two fixing grooves, and the protrusion engages with the fixing grooves.

[0012] Furthermore, the mounting block and mounting groove are provided with threaded grooves inside, and bolts are threadedly connected inside the threaded grooves.

[0013] Furthermore, a protective component is installed on the outer surface of the clamping plate. The protective component includes two sliding rods slidably connected inside the clamping plate, and a silicone pad is fixedly connected to one end of each sliding rod.

[0014] Furthermore, a second spring is sleeved on the outer surface of the slide rod. One end of the second spring is connected to a silicone pad, and the other end is connected to the side of the clamping plate. A limit plate is fixedly connected to the other end of the slide rod.

[0015] Furthermore, a negative pressure machine is fixedly connected to the upper surface of the connecting frame, and two negative pressure pipes are provided on the outer surface of the negative pressure machine. One end of the two negative pressure pipes is threaded to a connecting pipe, which is inserted into the outer surface of the silicone pad.

[0016] Furthermore, two support blocks are fixedly connected to the outer surface of the connecting frame, and the outer surface of the negative pressure pipe is connected to the interior of the support blocks.

[0017] Furthermore, a mounting plate is fixedly connected to the upper surface of the fixing block, and the mounting plate has multiple mounting holes inside.

[0018] Beneficial effects

[0019] (1) This solution can precisely adjust the position of the two clamping plates by the cooperation of the motor, the double-acting screw and the sleeve, so as to ensure that the workpiece is clamped evenly. At the same time, the cooperation of the slide rail and the slider ensures that the sleeve moves smoothly along the thread on the surface of the double-acting screw, avoiding deviation and instability.

[0020] (2) The clamping plate can be quickly removed from the device by the cooperation of the mounting slot and the mounting block, allowing the staff to quickly replace different types of clamping plates, so as to adapt to workpieces of various shapes and sizes. At the same time, the double fixing of the mounting block by the protrusion moving slot, spring, fixing slot, threaded slot and bolt ensures the firmness of the mounting block and prevents it from loosening during use.

[0021] (3) Through the cooperation of the slide bar, spring 2, silicone pad, negative pressure machine and negative pressure tube, it can better fit the workpiece surface and enhance the clamping stability. At the same time, it reduces the impact of direct clamping force on the workpiece and prevents scratches or indentations on the workpiece surface. Attached Figure Description

[0034] The present invention will be further described below with reference to the embodiments.

[0035] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-5 A clamping device with good fit includes a connecting frame 1 and a fixing block 101.

A motor 202 is fixedly connected to the side of the side plate 201. A bidirectional lead screw 203 is fixedly connected to the output shaft end of the motor 202 through a coupling. Two sleeves 204 are threadedly connected to the outer surface of the bidirectional lead screw 203. A slide rail 205 is installed at the bottom of the connecting frame 1. A slider 206 is slidably connected inside the slide rail 205. The lower surface of the slider 206 is connected to the sleeve 204. A protective member 4 is installed on the outer surface of the clamping plate 303. The protective member 4 includes a slidably connected... Inside the clamping plate 303 are two sliding rods 401. One end of the sliding rod 401 is fixedly connected to a silicone pad 402. A spring 403 is sleeved on the outer surface of the sliding rod 401. One end of the spring 403 is connected to the silicone pad 402, and the other end is connected to the side of the clamping plate 303. A limit plate is fixedly connected to the other end of the sliding rod 401. A negative pressure machine 404 is fixedly connected to the upper surface of the connecting frame 1. Two negative pressure pipes 405 are provided on the outer surface of the negative pressure machine 404. One end of the two negative pressure pipes 405 is threadedly connected to a connecting pipe, which is inserted into the outer surface of the silicone pad 402.

[0037] In one embodiment of this utility model, the connecting frame 1 is fixed to the mechanical equipment to be used through the mounting holes on the mounting plate 103. The workpiece to be clamped is then placed between the two clamping plates 303. The motor 202 is then started, and the motor 202 drives the bidirectional lead screw 203 to rotate through the coupling. When the bidirectional lead screw 203 rotates, the two sleeves 204 move along the threads on the surface of the bidirectional lead screw 203, thereby adjusting the position of the clamping plates 303 on both sides. The workpiece is fixed by the silicone pad 402 on the surface of the clamping plate 303. When the silicone pad 402 fixes the workpiece, it will drive the spring 403 to be compressed and drive the slide rod 401 to move backward, thereby ensuring that the silicone pad 402 and the clamping plate 303 are in close contact with the workpiece, providing cushioning protection.

[0038] In some embodiments, such as Figure 1-5 As shown, in a preferred embodiment of the present invention, a disassembly component 3 is mounted on the outer surface of the clamping component 2.

[0039] In this embodiment of the utility model, the disassembly component 3 is fixedly installed in the mounting groove 301 below the two sleeves 204.

The other end of spring 305 is connected to the inside of the moving groove 304. Two fixing grooves 307 are opened on the outer surface of the mounting block 302. The protrusion 306 is snapped into the fixing groove 307. Threaded grooves 308 are opened inside the mounting block 302 and the mounting groove 301. Bolts 309 are threadedly connected inside the threaded grooves 308.

[0040] In one embodiment of this utility model, the bolt 309 is unscrewed from the threaded groove 308, and the handheld mounting block 302 and clamping plate 303 are moved downwards to remove the mounting block 302 from the mounting groove 301, thereby removing the clamping plate 303 from the device. At the same time, the silicone pad 402 is separated from the device by the cooperation of the connecting pipe and the negative pressure pipe 405, and the corresponding clamping plate 303 is installed. At this time, the mounting block 302 is inserted into the mounting groove 301, and the protrusion 306 automatically engages with the fixing groove 307 under the action of the spring 305, achieving quick installation. At the same time, the bolt 309 is screwed into the threaded groove 308 to further fix the mounting block 302 and ensure its stability.

[0041] The working principle of this utility model is as follows: In use, the connecting frame 1 is fixed to the mechanical equipment to be used through the mounting holes on the mounting plate 103. Then, the workpiece to be clamped is placed between the two clamping plates 303. Then, the motor 202 is started. The motor 202 drives the bidirectional lead screw 203 to rotate through the coupling. When the bidirectional lead screw 203 rotates, the two sleeves 204 move along the threads on the surface of the bidirectional lead screw 203, thereby adjusting the position of the two clamping plates 303. And through the silicone pad 4 on the surface of the clamping plate 303... 02. Fix the workpiece. When the silicone pad 402 fixes the workpiece, it will drive the spring 403 to compress and drive the slide bar 401 to move backward, thereby ensuring that the silicone pad 402 and the clamping plate 303 are in close contact with the workpiece and provide buffer protection. Furthermore, when the sleeve 204 moves, it will drive the slider 206 to slide in the slide rail 205, ensuring the smooth movement of the sleeve 204 and the clamping plate 303. At the same time, the negative pressure machine 404 is started, and the silicone pad 402 is subjected to negative pressure adsorption through the negative pressure pipe 405 to enhance the clamping effect.

[0042] Subsequently, when clamping other types of workpieces, first unscrew the bolt 309 from the threaded groove 308, then move the hand-held mounting block 302 and clamping plate 303 downwards to remove the mounting block 302 from the mounting groove 301, thereby removing the clamping plate 303 from the device. At the same time, the silicone pad 402 is separated from the device through the cooperation of the connecting pipe and the negative pressure pipe 405, and the corresponding clamping plate 303 is installed. At this time, the mounting block 302 is inserted into the mounting groove 301, and the protrusion 306 automatically engages with the fixing groove 307 under the action of the spring 305, achieving quick installation. At the same time, the bolt 309 is screwed into the threaded groove 308 to further fix the mounting block 302 and ensure its stability.
