Description

Technical Field

[0001] The utility model relates to the technical field of control cabinet processing devices, and specifically refers to a fixing tooling for processing control cabinet cabinets. Background Technique

[0002] As an important part of electrical equipment, control cabinets are widely used in fields such as industrial control and power systems. The cabinets of control cabinets are usually made of metal sheets through a series of processing techniques, such as welding, grinding, etc. During these processing processes, it is necessary to firmly fix the cabinet to ensure the accuracy and quality of processing.

[0003] However, the traditional fixing tooling for control cabinet cabinets has obvious defects. On the one hand, most traditional fixing toolings fix the cabinet by external clamping. When applying the clamping force in this way, it is easy to cause excessive local stress on the cabinet, resulting in deformation of the cabinet and affecting the structural integrity and appearance quality of the cabinet. On the other hand, the traditional fixing tooling lacks effective control of the clamping force. Due to the inability to accurately control the clamping force, it may occur that the clamping is too loose, resulting in displacement of the cabinet during the processing, affecting the processing accuracy; or the clamping is too tight, causing damage to the cabinet. These problems not only reduce the processing efficiency and quality of control cabinet cabinets, but also increase the production cost and scrap rate. Content of the Utility Model

[0004] (I) Technical Problem

[0005] The utility model aims to provide a fixing tooling for processing control cabinet cabinets to solve the problems existing in the traditional fixing tooling during the processing of cabinets, such as easy deformation of the cabinet and improper control of the clamping force, and improve the accuracy, quality and efficiency of cabinet processing.

[0006] (II) Technical Content

[0007] To solve the above technical problems, the technical solution of the utility model is: a fixing tooling for processing control cabinet cabinets, including a base, a supporting plate for placing the cabinet is fixedly arranged on the upper end surface of the base, a chute is fixedly arranged on the upper end surface of the supporting plate, a bidirectional driving mechanism is arranged inside the chute, the two output ends of the bidirectional driving mechanism are symmetrically arranged and clamping components for clamping the inner wall of the cabinet are fixedly arranged at the upper ends, the two clamping components are mirror images of each other and cooperate to clamp the cabinet from the inside, a pressure sensor is fixedly arranged inside one end of the clamping component close to the inner wall of the cabinet, a PLC controller is fixedly arranged on the base, and the bidirectional driving mechanism and the pressure sensor are both electrically connected to the PLC controller.

[0008] Further, the bidirectional driving mechanism includes a bidirectional lead screw rotatably arranged inside the sliding groove, and further includes a motor fixedly arranged outside the sliding groove for driving the bidirectional lead screw to rotate. Symmetrically threaded connection blocks are arranged on both sides of the center of the bidirectional lead screw, and the two clamping components are respectively fixedly arranged on the upper ends of the two blocks.

[0009] Further, the clamping component includes a U-shaped frame. Plug cavities are arranged at both end parts of the U-shaped frame. A clamping disc is movably inserted inside the plug cavity, and the pressure sensor is fixedly arranged on the inner side surface of the plug cavity.

[0010] Further, a rubber cushion layer is fixedly arranged on the side surface of the clamping disc in contact with the inner wall of the cabinet body.

[0011] Further, a number of uniformly distributed rubber protrusions for increasing the friction force are fixedly arranged on the outer side surface of the rubber cushion layer.

[0012] (III) Technical effects

[0013] The advantages of the present utility model compared with the prior art are as follows: This tooling adopts the method of clamping from the inside of the cabinet body, avoiding the problem of local excessive force and deformation of the cabinet body caused by external clamping, and ensuring the structural integrity and good appearance quality of the cabinet body. By arranging a pressure sensor inside the clamping component, the clamping force can be monitored in real time and adjusted by the PLC controller to ensure that the clamping is both stable and will not cause excessive damage to the cabinet body. The stable and appropriate clamping can effectively reduce the displacement and shaking of the cabinet body during the processing, thereby significantly improving the accuracy and quality of processing procedures such as welding and grinding. The rubber cushion layer and the rubber protrusions not only increase the friction force but also play a certain protective role on the surface of the cabinet body during the clamping process, reducing scratches and abrasions.

[0023] The following further details the present utility model with reference to the drawings.

[0024] Combined with the attached Figure 1 To the attached Figure 6 To solve the above technical problems, the technical solution of the present utility model is: a fixing tooling for the processing of the control cabinet body, including a base 1, and a supporting plate 2 for placing the cabinet body is fixedly provided on the upper end surface of the base 1. A slide groove 3 is fixedly provided on the upper end surface of the supporting plate 2. A bidirectional driving mechanism is provided inside the slide groove 3. The two output ends of the bidirectional driving mechanism are symmetrically arranged and clamping assemblies 4 for clamping the inner wall of the cabinet body are fixedly provided at the upper ends. The two clamping assemblies 4 are mirror images of each other and cooperate with each other to clamp the cabinet body from the inside. A pressure sensor 5 is fixedly provided inside one end of the clamping assembly 4 close to the inner wall of the cabinet body. A PLC controller 6 is fixedly provided on the base 1. The bidirectional driving mechanism and the pressure sensor 5 are both electrically connected to the PLC controller 6.

[0025] The bidirectional driving mechanism includes a bidirectional lead screw 7 rotatably arranged inside the chute 3, and further includes a motor 8 fixedly arranged outside the chute 3 for driving the bidirectional lead screw 7 to rotate. On both sides of the center of the bidirectional lead screw 7, symmetrically threaded connection is provided with sliders 9, and the two clamping assemblies 4 are respectively fixedly arranged at the upper ends of the two sliders 9. The clamping assembly 4 includes a U-shaped frame 10. Insertion cavities 12 are provided at both ends of the U-shaped frame 10. Inside the insertion cavities 12, a clamping disc 11 is movably inserted. Inside the inner side surface of the insertion cavities 12, the pressure sensors 5 are fixedly arranged. On the side surface of the clamping disc 11 in contact with the inner wall of the cabinet, a rubber cushion layer 13 is fixedly arranged. On the outer side surface of the rubber cushion layer 13, a number of uniformly distributed rubber protrusions 14 for increasing the friction force are fixedly arranged.

[0026] The working principle of a fixing tool for the processing of a control cabinet body of the present utility model is as follows: When it is necessary to process the control cabinet body, the cabinet body is placed on the supporting plate 2. The motor 8 is started, and the motor 8 drives the bidirectional lead screw 7 to rotate. The rotation of the bidirectional lead screw 7 causes the two sliders 9 threadedly connected thereto to move towards or away from each other along the chute 3. The movement of the sliders 9 drives the clamping assemblies 4 fixed thereon to approach or move away from the inner wall of the cabinet body. When the clamping assembly 4 contacts the inner wall of the cabinet body, the clamping disc 11 is squeezed, and the pressure sensor 5 transmits the sensed pressure signal to the PLC controller 6. The PLC controller 6 controls the rotation of the motor 8 according to the preset pressure value, so as to adjust the clamping force of the clamping assembly 4 on the cabinet body, and achieve stable and appropriate clamping.

[0027] The usage process of a fixing tool for the processing of a control cabinet body of the present utility model is as follows:

[0028] 1. Preparation work: The control cabinet body to be processed is stably placed on the supporting plate 2. The cabinet body refers to a semi-finished product, without a cabinet door and other accessories, and is placed upside down on the supporting plate 2 with the opening facing downwards.

[0029] 2. Start the equipment: Connect the power supply and turn on the motor 8.

[0030] 3. Clamp the cabinet body: The motor 8 drives the bidirectional lead screw 7 to rotate, so that the two sliders 9 drive the clamping assemblies 4 to move towards the inside of the cabinet body. The clamping disc 11 gradually contacts the inner wall of the cabinet body, and the rubber cushion layer 13 and the rubber protrusions 14 are closely attached to the inner wall, increasing the friction force.

[0031] 4. Pressure monitoring and adjustment: The pressure sensor 5 monitors the clamping pressure in real time and transmits the signal to the PLC controller 6. If the pressure does not reach the preset value, the motor 8 continues to rotate to increase the clamping force; if the pressure is too high, the motor 8 rotates in reverse to reduce the clamping force until a suitable clamping state is reached.

[0032] 5. Perform processing: After the cabinet body is stably clamped, the operator can perform processing operations such as welding and grinding on the outside of the cabinet body.

[0033] 6. Completion of machining and clamping / unclamping: After the machining is completed, the PLC controller 6 is used to control the motor 8 to reverse, so that the clamping assembly 4 releases the cabinet body, and the machined cabinet body is taken down.

[0034] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the purpose of the creation of the present utility model, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
