Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinet shell processing, in particular to a clamping plate spacing adjustable fixing mechanism. Background Art

[0002] At present, distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets and metering cabinets. They are the final equipment of the distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in occasions where the load is relatively dispersed and there are fewer circuits; motor control centers are used in occasions where the load is concentrated and there are more circuits. They distribute the electrical energy of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load.

[0003] Among them, when the distribution cabinet is being processed, 1. Plate cutting: the operator uses sawing machines, shearing machines and other tools to cut the plate into corresponding sizes according to the drawings and size requirements; 2. Stamping: Use punching machines or hydraulic presses and other equipment to punch the plate into molds for various parts of the distribution box; 3. Welding: The stamped parts are spliced ​​and welded to form the shell of the distribution box.

[0004] When stamping and punching the distribution cabinet shell, the distribution cabinet shell needs to be firmly fixed between two sets of clamping plates to facilitate stamping and punching of the distribution cabinet shell. However, when the market uses the clamping plates to clamp the distribution cabinet shell, not only the clamping force of the clamping plates is controlled, but also the thinner plate is easily squeezed and deformed. Therefore, a new technical solution needs to be designed to solve this problem. Utility Model Content

[0005] The utility model aims to provide a fixing mechanism with adjustable clamping plate spacing, which solves the problems raised in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fixing mechanism with adjustable clamping plate spacing, comprising a processing table, a moving seat is fixedly installed on one side of the processing table, a bidirectional screw is rotatably installed inside the moving seat, moving blocks are rotatably installed on both sides of the bidirectional screw, clamping plates are fixedly installed on the outer walls of two groups of the moving blocks, and clamping stabilization mechanisms are installed on the two groups of the clamping plates;

[0007] The clamping stabilization mechanism includes piston holes opened on both sides of the clamping plate, piston rods movably installed in the two groups of piston holes, detection plates fixedly installed on one side of the two groups of piston rods, and a pressure sensor fixedly installed in the middle of one side of the detection plate, and the pressure sensor corresponds to the clamping plate.

[0008] As an optional solution of the technical solution of the present application, the outer wall of each group of piston rods is sleeved with a spring, and the two sides of each group of springs are respectively fixed to the clamping plate and the outer wall of the detection plate, so that the detection plate can be automatically reset.

[0009] As an optional solution of the technical solution of the present application, a servo motor is fixedly installed in the middle of the side wall of the movable seat, the driving output end of the servo motor is connected to the transmission shaft, and the other end of the transmission shaft is fixedly installed on one end of the bidirectional screw rod, which can drive the bidirectional screw rod to rotate.

[0010] As an optional solution to the technical solution of the present application, a limiting groove is opened on one side of the inner part of the moving seat, and limiting sliders are slidably installed on both sides of the limiting groove. The two groups of limiting sliders are respectively fixed to the outer walls of the two groups of moving blocks, so as to limit the moving blocks.

[0011] As an optional solution of the technical solution of the present application, support frames are fixedly installed on both sides of the processing table, and limiting holes are provided on both sides of the two groups of support frames to support the limiting rods.

[0012] As an optional solution of the technical solution of the present application, a limiting rod is slidably installed in each group of the limiting holes, and the limiting rods of two adjacent groups are fixedly installed on one side of the splint, so as to limit the splint.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. In the technical solution of the present application, when the two sets of clamps move inward synchronously, they will clamp the distribution cabinet shell on the processing table. At the same time, as the two sides of the distribution cabinet shell continue to squeeze the clamping stabilization mechanism, the pressure sensor located on the inner wall of the detection plate will be squeezed with the clamp. When the pressure value of the pressure sensor reaches the set value, it will directly transmit the signal to the control processor to control the servo motor to stop driving, thereby ensuring that the two sets of clamps can firmly fix the distribution cabinet shell under the temperature support force.

[0015] 2. The technical solution of the present application is to open limit holes on both sides of the two groups of support frames, and a limit rod is slidably installed in each group of limit holes. When the servo motor is driven to drive the two groups of clamps to move left and right, the limit rods in the limit holes can be used to limit and support the two groups of clamps, thereby ensuring that the two groups of clamps can move left and right horizontally and clamp the distribution cabinet shell.

[0020] See also Figure 1-2 The utility model provides a technical solution: a fixing mechanism with adjustable clamping plate spacing, comprising a processing table 1, a moving seat 11 is fixedly installed on one side of the processing table 1, a bidirectional screw rod 13 is rotatably installed inside the moving seat 11, and moving blocks 14 are rotatably installed on both sides of the bidirectional screw rod 13, and clamping plates 2 are fixedly installed on the outer walls of the two groups of moving blocks 14, and clamping stabilization mechanisms are installed on the two groups of clamping plates 2;

[0021] The clamping stabilization mechanism includes piston holes 21 opened on both sides of the clamp plate 2, piston rods 22 movably installed in the two groups of piston holes 21, detection plates 23 fixedly installed on one side of the two groups of piston rods 22, and a pressure sensor 24 fixedly installed in the middle of one side of the detection plate 23, and the pressure sensor 24 corresponds to the clamp plate 2.

[0022] In this technical solution, when the two groups of clamps 2 move inward synchronously, they will clamp the distribution cabinet shell on the processing table 1. At the same time, as the two sides of the distribution cabinet shell continue to squeeze the clamping stabilization mechanism, the pressure sensor 24 located on the inner wall of the detection plate 23 will be squeezed with the clamp 2. When the pressure value of the pressure sensor 24 reaches the set value, the signal will be directly transmitted to the control processor to control the servo motor 12 to stop driving, thereby ensuring that the two groups of clamps 2 can firmly fix the distribution cabinet shell under the temperature support force.

[0023] In some technical solutions, support frames 32 are fixedly installed on both sides of the processing table 1, and limiting holes 33 are provided on both sides of the two groups of support frames 32 to support the limiting rods 34. A limiting rod 34 is slidably installed in each group of limiting holes 33. Two adjacent groups of limiting rods 34 are fixedly installed on one side of the splint 2, so as to limit the splint 2.

[0024] In this technical solution, when the driving servo motor 12 drives the two groups of clamps 2 to move left and right, the two groups of clamps 2 can be limited and supported by the limit rod 34 to ensure that the two groups of clamps 2 move left and right in the horizontal direction and clamp the distribution cabinet shell.

[0025] In some technical solutions, a servo motor 12 is fixedly installed in the middle of the side wall of the moving seat 11. The driving output end of the servo motor 12 is connected to the transmission shaft, and the other end of the transmission shaft is fixedly installed on one end of the bidirectional screw rod 13, which can drive the bidirectional screw rod 13 to rotate. A limiting groove 3 is opened on one side of the inside of the moving seat 11, and limiting sliders 31 are slidably installed on both sides of the limiting groove 3. Two groups of limiting sliders 31 are respectively fixedly installed on the outer walls of the two groups of moving blocks 14, and the moving blocks 14 can be limited.

[0026] In this technical solution, when the driving servo motor 12 drives the bidirectional screw rod 13 to rotate, the limiting slider 31 in the limiting slide groove 3 can limit the moving blocks 14 at both ends of the bidirectional screw rod 13 to ensure that the two groups of moving blocks 14 move inward and outward synchronously.

[0027] In some technical solutions, the outer wall of each group of piston rods 22 is sleeved with a spring 25, and both sides of each group of springs 25 are fixedly installed with the clamping plate 2 and the outer wall of the detection plate 23 respectively, so that the detection plate 23 can be automatically reset.

[0028] In this technical solution, when the two groups of clamps 2 move outward synchronously, the spring 25 installed on the outer wall of the piston rod 22 can support the detection plate 23, so that the detection plate 23 can clamp the distribution cabinet housing for the second time.

[0029] When a splint spacing adjustable fixing mechanism is used, it should be noted that the utility model is a splint spacing adjustable fixing mechanism, and each component is a universal standard part or a component known to technical personnel in this field, and its structure and principle can be known to technical personnel through technical manuals or through conventional experimental methods.

[0030] When in use, first place the switch cabinet housing to be clamped on the processing table 1, and drive the servo motor 12 to drive the bidirectional screw 13 to rotate. The two sets of moving blocks 14 threadedly connected to the bidirectional screw 13 will drive the two sets of clamping plates 2 to move inward and outward synchronously. When the two sets of clamping plates 2 move inward synchronously, the switch cabinet housing on the processing table 1 will be clamped. At the same time, as the two sides of the switch cabinet housing continuously squeeze the clamping stabilization mechanism, the pressure sensor 24 located on the inner wall of the detection plate 23 will be squeezed with the clamping plate 2. When the pressure value received by the pressure sensor 24 reaches When the set value is reached, the signal will be directly transmitted to the control processor to control the servo motor 12 to stop driving, ensuring that the two groups of splints 2 can firmly fix the distribution cabinet shell under the temperature support force. At the same time, limit holes 33 are opened on both sides of the two groups of support frames 32, and limit rods 34 are slidably installed in each group of limit holes 33. When the servo motor 12 is driven to drive the two groups of splints 2 to move left and right, the limit rods 34 in the limit can limit and support the two groups of splints 2, ensuring that the two groups of splints 2 can move left and right in the horizontal direction, and the distribution cabinet shell is clamped and fixed.
