Description

Technical Field

[0001] The present application relates to the technical field of electric clamps, and in particular to a clamping structure of an electric clamp. Background Art

[0002] Electric clamps are composed of motors, transmission devices, switches and power supply systems. Electric clamps are mainly used to clamp workpieces to ensure that they remain in a stable position during processing or assembly.

[0003] In the prior art, electric clamps are usually operated by placing an object directly in the middle of the clamp and clamping the object using a clamping arm. This operation method is simple and direct, but there is a problem that the object may be offset or unstable during the clamping process.

[0004] To solve this problem, the existing technology usually adopts an automated control method, introduces sensors and feedback systems to monitor the clamping force and object position, and automatically adjusts the position and force of the clamping arm according to preset parameters. However, there is a problem with the traditional automated control method, that is, the sensor may be affected by environmental interference or failure, resulting in inaccurate measurement, and the feedback system may have delays or errors, affecting the accurate control of the clamping arm. Utility Model Content

[0005] The purpose of the present application is to solve the disadvantage of unstable clamping in the prior art and to propose an electric clamp clamping structure.

[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: a connecting column is fixedly connected to the upper surface of the body, a chassis is installed on the upper surface of the connecting column, a motor is arranged inside the chassis, a moving clamp is fixedly connected to the output end of the motor, a fixed clamp is fixedly connected to one end of the chassis, the fixed clamp is slidably connected to the moving clamp, a switch is arranged on the arc surface of the connecting column, the switch is electrically connected to the motor, a clamping device is arranged on the surface of the fixed clamp, the clamping device comprises two fixed blocks, one end of the fixed block is fixedly connected to the fixed clamp, the two fixed blocks are symmetrically distributed at the two ends of the fixed clamp, a positioning plate is slidably connected inside the fixed block, a connecting plate is fixedly connected to the upper surface of the positioning plate, two limit blocks are slidably connected to the inner wall of the connecting plate, an adjusting plate is slidably connected to one end of the two limit blocks close to each other, a welding rod is slidably connected inside the adjusting plate, two auxiliary blocks are fixedly connected to the arc surface of the welding rod, and the auxiliary blocks are interference-connected with the positioning plate.

[0007] The effect achieved by the above components is: when clamping an object, align the limit block with the object, then pull the adjustment plate, the adjustment plate moves the two limit blocks close to each other until the object is tightly clamped, then push the welding rod to connect the auxiliary block with the positioning plate, then pull the positioning plate, the positioning plate will drive the object to move, and when it reaches the fixed clamp, start the machine to move the mobile clamp to clamp the object.

[0008] Preferably, a spring is fixedly connected to the surface of the adjustment plate, and the other end of the spring is fixedly connected to the connecting plate.

[0009] The effect achieved by the above components is: during the clamping process, the spring will be compressed when the positioning plate moves, and when the clamping is completed and the fixing is released, the spring can help the positioning plate to automatically reset.

[0010] Preferably, a plurality of rubber pads are fixedly connected to the sides of the two limit blocks that are close to each other, and the surfaces of the rubber pads are provided with anti-slip grooves.

[0011] The effects achieved by the above components are: the anti-skid patterns on the surface of the rubber pad can increase the friction force and effectively prevent the workpiece from sliding or moving during the clamping process.

[0012] Preferably, the arc surface of the adjustment plate is fixedly connected with a screw rod, and both ends of the screw rod are threadedly connected with nuts.

[0013] The effects achieved by the above components are: the screw is fixedly connected to the adjustment plate through the nut, which can provide reliable force transmission and position fixation, and ensure the stability and reliability of the clamping mechanism during operation.

[0014] Preferably, a storage device is provided on one side of the body, and the storage device includes a connecting block, one end of the connecting block is fixedly connected to the body, two elastic blocks are interference-connected inside the connecting block, and the same storage box is fixedly connected to one side of the two elastic blocks close to each other, and an electric tester is provided inside the storage box.

[0015] The effect achieved by the above components is: when using the storage device, the storage box is pulled out, and then the items are placed in the storage box for retrieval. The setting of the storage device provides the electric clamp clamping mechanism with the function of convenient storage and use of tools, while ensuring the firm fixation and protection of the tools, thereby improving the convenience and efficiency of use.

[0016] Preferably, a magnetic plate is provided on the upper surface of the body, and the magnetic plate is adsorbed on the body.

[0017] The effect achieved by the above components is that by placing the storage box on the magnetic board, the risk of losing tools or parts can be reduced, especially in a busy working environment, to avoid tools being placed in inappropriate locations and causing loss.

[0018] Preferably, one end of the storage box away from the body is fixedly connected with a handle, and the handle is made of stainless steel.

[0019] The effects achieved by the above components are: the stainless steel handle is usually smooth and warm, providing a good hand feel, making the user feel more comfortable and convenient when extracting or moving the storage box.

[0020] In summary, the beneficial effects of this application are:

[0021] In the present application, the object to be clamped is placed on the upper surface of the fixed clamp to ensure that the object is within the range of the clamp. First, the operator aligns the two limit blocks with the two sides of the object respectively. At this time, the limit blocks are at the farthest position. Then, the adjustment plate is pulled to make the adjustment plate drive the two limit blocks to approach each other until the limit blocks tightly clamp the object. After the limit blocks clamp the object, the operator pushes the welding rod. The arc surface of the welding rod is fixedly connected to two auxiliary blocks. When the welding rod is pushed, the two auxiliary blocks will contact and fix with the positioning plate. The auxiliary blocks and the positioning plate are tightly connected through interference fit to ensure that the positioning plate and the clamped object are stable. The object is fixed and does not move. Then the operator pulls the positioning plate, and the positioning plate brings the object to the position of the fixed clamp. Once the object is positioned in place, the switch is pressed to start the motor, so that the mobile clamp starts to move. Under the action of the motor, the mobile clamp slides along the upper surface of the fixed clamp, gradually approaches and clamps the object, and finally fixes the object firmly between the fixed clamp and the mobile clamp. At this time, the electric clamp can perform further operations, such as handling and processing. The role of the spring is to help the positioning plate to automatically reset, and the screw and nut are to provide reliable force transmission and position fixation, thereby ensuring the stability and reliability of the clamping mechanism during operation.

[0022] In the present application, one end of the connecting block is fixedly connected to the body to ensure that the entire storage device is firmly installed on the clamping mechanism of the electric clamp. Two elastic blocks are installed inside the connecting block through an interference fit. This structure can not only stabilize the storage box, but also provide a certain buffer and resilience for the pulling and pulling of the storage box. The elastic block can absorb external vibrations, protect internal tools such as electric testers, and reduce the risk of damage caused by vibration. When in use, hold the handle of the storage box away from the body, pull the storage box out of the body, and place the tools or items to be stored in the storage box. A magnetic plate is provided on the upper surface of the body. When the storage device is used, the storage box can be placed on the magnetic plate. The magnetic plate will adsorb the storage box, reducing the risk of losing tools or parts, thereby reducing the possibility of losing tools. Through this design, users can easily take and place tools, especially electric testers, and can quickly find and use them when needed. BRIEF DESCRIPTION OF THE DRAWINGS

The interior of the fixed block 201 is slidably connected to a positioning plate 202, and the upper surface of the positioning plate 202 is fixedly connected to a connecting plate 203. The inner wall of the connecting plate 203 is slidably connected to two limit blocks 204, and the ends of the two limit blocks 204 close to each other are slidably connected to an adjustment plate 205, and the adjustment plate 205 is slidably connected to the inner wall of the connecting plate 203. 05 is internally connected with a welding rod 206 for sliding movement. The arc surface of the welding rod 206 is fixedly connected with two auxiliary blocks 207. The auxiliary blocks 207 are interference-connected with the positioning plate 202. When clamping an object, the limit block 204 is aligned with the object, and then the adjustment plate 205 is pulled. The adjustment plate 205 moves the two limit blocks 204 to move closer to each other until the object is tightly clamped. Then the welding rod 206 is pushed to connect the auxiliary block 207 with the positioning plate 202. Then the positioning plate 202 is pulled. The positioning plate 202 will drive the object to move, and when it reaches the fixed clamp 4, the machine is started to move the mobile clamp 5 to clamp the object. The surface of the adjusting plate 205 is fixedly connected with a spring 209, and the other end of the spring 209 is fixedly connected to the connecting plate 203. During the clamping process, the spring 209 will be compressed when the positioning plate 202 moves. When the clamping is completed, the fixation is released, and the spring 209 can help the positioning plate 202 to automatically reset. The sides of the two limit blocks 204 close to each other are fixedly connected with a plurality of rubber pads 208. The surface of the rubber pads 208 is provided with anti-skid patterns.

The arc surface of the adjusting plate 205 is fixedly connected with a screw rod 210, and both ends of the screw rod 210 are threadedly connected with nuts 211. The screw rod 210 is fixedly connected to the adjusting plate 205 through the nut 211, which can provide reliable force transmission and position fixation, thereby ensuring the stability and reliability of the clamping mechanism during operation.

[0032] Reference Figure 5As shown, in this embodiment: the storage device 3 includes a connecting block 31, one end of the connecting block 31 is fixedly connected to the body 1, the connection block 31 is internally connected with two elastic blocks 32 by interference fit, the two elastic blocks 32 are fixedly connected to the same storage box 33 on one side close to each other, and an electric test pen 34 is arranged inside the storage box 33. When the storage device 3 is used, the storage box 33 is pulled out, and then the items are placed in the storage box 33 for taking out. The setting of the storage device 3 provides the electric clamp clamping mechanism with the function of convenient storage and use of tools, while ensuring the firm fixation and protection of the tools, improving In order to ensure convenience and efficiency of use, a magnetic plate 35 is provided on the upper surface of the body 1, and the magnetic plate 35 is adsorbed on the body 1. By placing the storage box 33 on the magnetic plate 35, the risk of losing tools or parts can be reduced, especially in a busy working environment, to avoid tools being placed in inappropriate positions and caused to be lost. The end of the storage box 33 away from the body 1 is fixedly connected with a handle 36. The handle 36 is made of stainless steel. The stainless steel handle 36 usually has a smooth and warm surface, providing a good hand feel, so that the user feels more comfortable and convenient when extracting or moving the storage box 33.

[0033] Working principle: place the object to be clamped on the upper surface of the fixed clamp 4 to ensure that the object is within the range of the clamp. First, the operator aligns the two limit blocks 204 with the two sides of the object respectively. At this time, the limit blocks 204 are at the farthest position. Then, pull the adjustment plate 205 so that the adjustment plate 205 drives the two limit blocks 204 to approach each other until the limit blocks 204 tightly clamp the object. After the limit blocks 204 clamp the object, the operator pushes the welding rod 206. The arc surface of the welding rod 206 is fixedly connected to two auxiliary blocks 207. When the welding rod 206 is pushed, the two auxiliary blocks 207 will contact and fix with the positioning plate 202. The auxiliary blocks 207 and the positioning plate 202 are tightly connected through interference fit to ensure that the positioning plate 202 and the clamped object are stable and motionless, and then the operator pulls the positioning plate 202, and the positioning plate 202 brings the object to the position of the fixed clamp 4. Once the object is positioned in place, press the switch 9 to turn on the motor 8, so that the mobile clamp 5 starts to move. Under the action of the motor 8, the mobile clamp 5 slides along the upper surface of the fixed clamp 4, gradually approaches and clamps the object, and finally fixes the object firmly between the fixed clamp 4 and the mobile clamp 5. At this time, the electric clamp can perform further operations, such as handling, processing, etc. The spring 209 is provided to help the positioning plate 202 to automatically reset, and the screw 210 and the nut 211 are provided to provide reliable force transmission and position fixation, thereby ensuring the stability and reliability of the clamping mechanism during operation.

[0034] One end of the connecting block 31 is fixedly connected to the body 1 to ensure that the entire storage device 3 is firmly installed on the clamping mechanism of the electric clamp. Two elastic blocks 32 are installed inside the connecting block 31 through an interference fit. This structure can not only stabilize the storage box 33, but also provide a certain buffer and resilience for the pulling and pulling of the storage box 33. The elastic block 32 can absorb external vibrations, protect internal tools such as the electric tester 34, and reduce the risk of damage caused by vibration. When in use, hold the storage box 33 away from the handle 36 of the body 1, pull the storage box 33 out of the body 1, and place the tools or items to be stored in the storage box 33. A magnetic plate 35 is provided on the upper surface of the body 1. When the storage device 3 is in use, the storage box 33 can be placed on the magnetic plate 35, and the magnetic plate 35 will absorb the storage box 33, reducing the risk of losing tools or parts, thereby reducing the possibility of losing tools. Through this design, users can easily take and place tools, especially the electric tester 34, and can quickly find and use them when needed.
