Description

Technical Field

[0001] This utility model belongs to the field of resistor sheet production technology, specifically relating to a limit device for a surge arrester resistor sheet grinding machine. Background Technology

[0002] Surge arrester resistor elements (also known as valve elements) are core components in power systems for limiting overvoltage. Their surface flatness directly affects the surge arrester's current-carrying capacity and protective characteristics. The grinding process is a critical step in resistor element manufacturing, requiring precision grinding of both sides of the resistor element using equipment such as grinding machines to control thickness tolerances. During the grinding process, precise positioning of the surge arrester resistor element is necessary to ensure grinding accuracy and quality.

[0003] Patent CN217194341U discloses a "grinding machine, including a support body and a connecting ring, with a limiting block at the bottom of a second arc-shaped limiting plate. This grinding machine, through the setting of the limiting toothed plate, prevents the resistance sheet from rotating. Through the coordinated arrangement of the limiting post, limiting block, and connecting ring, the second arc-shaped limiting plate can press the resistance sheet firmly during use, thereby preventing the resistance sheet from shaking during grinding and facilitating grinding. Through the setting of the limiting rod and the second limiting groove, the grinding machine prevents the connecting spring from tilting. Through the coordinated arrangement of the connecting block, connecting rod, and connecting spring, the connecting half-ring and the limiting half-ring can be integrated with the uncovered annular collection tank during use, facilitating the processing of abrasive materials."

[0004] Although the existing technology can compress and limit the resistor sheet, the debris generated during the grinding process falls onto the periphery of the resistor sheet in the open annular collection container and accumulates around it. When the resistor sheet is removed after grinding, the debris accumulated around it falls to the bottom of the resistor sheet due to the loss of support. When grinding other resistor sheets, the debris at the bottom of the resistor sheet must be pushed away before the resistor sheet can be placed in that position. However, it is laborious and inconvenient to push away the debris in the placement area every time a resistor sheet is replaced, so it needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a limiting device for a surge arrester resistor grinding machine in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A limiting device for a surge arrester resistor grinding machine includes a limiting seat, a limiting mechanism and a chip-removing mechanism installed in the limiting seat. The top of the limiting seat has a groove. The limiting mechanism includes a fixed clamping plate and a movable clamping plate disposed in the groove of the limiting seat, and a driving mechanism installed in the limiting seat for driving the movable clamping plate to move.

[0008] The chip-removing mechanism includes a trapezoidal block slidably disposed within a limiting seat, and an elastic diaphragm fixedly disposed between the bottom of the sink groove of the limiting seat and the top of the trapezoidal block. The elastic diaphragm is located below the fixed clamping plate and the movable clamping plate. A U-shaped rod is slidably disposed on one side of the limiting seat, and a triangular plate is fixedly disposed at the bottom end of the U-shaped rod for guiding the trapezoidal block upward when the movable clamping plate pushes the U-shaped rod.

[0009] As a further optimization of this utility model, a fixing rod is fixedly provided in the groove of the limiting seat, and the fixing clamping plate is fixedly connected to one end of the fixing rod.

[0010] As a further optimization of this utility model, the driving mechanism includes an electric push rod fixedly disposed in the groove of the limiting seat, and the movable clamping plate is fixedly connected to one end of the electric push rod.

[0011] As a further optimization of this utility model, rubber pads are fixedly provided on the inner sides of both the fixed clamping plate and the movable clamping plate.

[0012] As a further optimization of this utility model, a fixing groove is provided at the bottom of the sink groove of the limiting seat, the edge of the elastic diaphragm is fixedly connected to the fixing groove of the limiting seat, the middle part of the rubber pad is movably disposed in the fixing groove of the limiting seat, a working groove is provided in the limiting seat, the bottom end of the U-shaped rod is slidably connected to the working groove of the limiting seat, and the bottom end of the trapezoidal block penetrates the limiting seat and extends into the working groove.

[0013] As a further optimization of this utility model, a push plate is fixedly provided at the top of the U-shaped rod, located directly below the electric push rod, and a spring is fixedly provided between one side of the push plate and the groove of the limiting seat.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The drive mechanism can move the movable clamping plate, which can then work with the fixed clamping plate to press and limit the resistor sheet, ensuring grinding accuracy and quality. When the movable clamping plate moves in the opposite direction after grinding and pushes the U-shaped rod, the triangular plate can guide the trapezoidal block upward. The upward-moving trapezoidal block will push the elastic diaphragm upward to form a cone shape, and the elastic diaphragm will collide with the movable clamping plate and other components to shake off the debris on the cone-shaped elastic diaphragm. This quickly removes the debris from the resistor sheet placement area, facilitating the replacement of the resistor sheet.

[0016] 2. Through the elastic force of the spring and in conjunction with the connection of the push plate, when the movable clamping plate moves towards the resistor sheet, the U-shaped rod is pushed into the limit seat and the U-shaped rod returns to its original position. The rubber pad can provide elastic protection for the resistor sheet that is pressed by the movable clamping plate and other components, avoiding the resistor sheet from being crushed by hard contact with the movable clamping plate and other components, making it convenient to use.

[0023] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Example

[0025] like Figure 1-5 As shown, a limiting device for a surge arrester resistor grinding machine includes a limiting seat 1, a limiting mechanism, and a chip removal mechanism. The limiting seat 1 is installed on the grinding machine, and the surge arrester resistors that are limited in the limiting seat 1 can be ground and processed by an external grinding machine.

[0026] like Figure 1-3As shown, the limiting mechanism and the dust-removing mechanism are installed in the limiting seat 1. The top of the limiting seat 1 is provided with a sink 11. The limiting seat 1 can support and accommodate the limiting mechanism and other structures. The sink 11 can collect the debris generated after grinding. Subsequently, the staff can use a vacuum cleaner to suck out the debris collected in the sink 11 to clean the top of the limiting seat 1.

[0027] like Figure 1-3 As shown, the limiting mechanism includes a fixed clamping plate 2 and a movable clamping plate 21 disposed in the recess 11 of the limiting seat 1, and a driving mechanism installed in the limiting seat 1 for driving the movable clamping plate 21 to move. A fixed rod 23 is fixedly disposed in the recess 11 of the limiting seat 1, and the fixed clamping plate 2 is fixedly connected to one end of the fixed rod 23. The driving mechanism includes an electric push rod 22 fixedly disposed in the recess 11 of the limiting seat 1, and the movable clamping plate 21 is fixedly connected to one end of the electric push rod 22. The fixed rod 23 can connect the limiting seat 1 and the fixed clamping plate 2. The electric push rod 22 is a miniature electric telescopic rod, and its model can be LAS10-021D.

[0028] After the electric push rod 22 extends and retracts, it can drive the movable clamping plate 21 to move laterally. After moving, the movable clamping plate 21 can cooperate with the fixed clamping plate 2 to press and limit the resistance sheet in the limiting seat 1, so that the resistance sheet is not easy to move during the subsequent grinding process, thereby ensuring the grinding accuracy and quality.

[0029] like Figure 1-3 As shown, rubber pads 24 are fixedly provided on the inner sides of both the fixed clamping plate 2 and the movable clamping plate 21. The rubber pads 24 can provide elastic and soft protection for the resistor sheet pressed by the movable clamping plate 21 and the fixed clamping plate 2, so as to prevent the resistor sheet from being crushed by hard contact with the movable clamping plate 21 and other components. When pressed, the rubber pads 24 will be compressed and deformed, so as not to affect the pressing and limiting of the resistor sheet by the movable clamping plate 21 and other components.

[0030] like Figure 3-5 As shown, the debris-removing mechanism includes a trapezoidal block 3 slidably disposed within the limiting seat 1, and an elastic diaphragm 31 fixedly disposed between the bottom of the recess 11 of the limiting seat 1 and the top of the trapezoidal block 3. The elastic diaphragm 31 is located below the fixed clamping plate 2 and the movable clamping plate 21. A U-shaped rod 32 is slidably disposed on one side of the limiting seat 1. A triangular plate 33 is fixedly disposed at the bottom end of the U-shaped rod 32 for guiding the trapezoidal block 3 upward when the movable clamping plate 21 pushes the U-shaped rod 32. The inclined side of the triangular plate 33 abuts against the inclined side of the trapezoidal block 3. In use, the surge arrester resistor can be placed on top of the elastic diaphragm 31 and the resistor can be positioned between the fixed clamping plate 2 and the movable clamping plate 21.

[0031] like Figure 3-5As shown, a fixing groove 13 is provided at the bottom of the sink 11 of the limiting seat 1. The edge of the elastic diaphragm 31 is fixedly connected to the fixing groove 13 of the limiting seat 1. The middle of the rubber pad 24 is movably disposed in the fixing groove 13 of the limiting seat 1. A working groove 12 is provided in the limiting seat 1. The bottom end of the U-shaped rod 32 is slidably connected to the working groove 12 of the limiting seat 1. The bottom end of the trapezoidal block 3 passes through the limiting seat 1 and extends into the working groove 12.

[0032] The limiting seat 1 can support and fix the elastic diaphragm 31 through the fixing groove 13, and the elastic diaphragm 31 can seal the top of the fixing groove 13, so that the grinding debris will not enter the working groove 12 through the fixing groove 13. The limiting seat 1 can support and limit the U-shaped rod 32 and other components through the working groove 12.

[0033] After grinding, the electric push rod 22 is shortened. At this time, the movable clamping plate 21 moves towards the electric push rod 22 and contacts and pushes the U-shaped rod 32. The triangular plate 33 moves with the U-shaped rod 32, so that the trapezoidal block 3 can be lifted upward by the guide of the triangular plate 33. The upward-moving trapezoidal block 3 will lift the middle area of ​​the elastic diaphragm 31 upward, so that the elastic diaphragm 31 forms a cone shape. Then, by controlling the electric push rod 22 to extend and retract slightly, the elastic diaphragm 31 collides repeatedly with the movable clamping plate 21 and other components. As a result, the debris on the elastic diaphragm 31 will move towards the bottom area of ​​the elastic diaphragm 31 under the vibration of the collision and its own gravity, thereby shaking off the debris on the cone-shaped elastic diaphragm 31, so as to quickly remove the debris in the resistor placement area and facilitate the replacement of the resistor.

[0034] like Figure 3-5 As shown, a push plate 34 is fixedly provided at the top of the U-shaped rod 32, located directly below the electric push rod 22. A spring 35 is fixedly provided between one side of the push plate 34 and the recess 11 of the limiting seat 1. The spring 35 can elastically connect the push plate 34 and the U-shaped rod 32. After the debris is shaken off, the electric push rod 22 is controlled to extend continuously, which can make the movable clamping plate 21 disengage from the push plate 34. At this time, under the elastic force of the spring 35, the U-shaped rod 32 can be pushed into the limiting seat 1 to return the U-shaped rod 32 to its original position, which is convenient for subsequent use.

[0035] It should be noted that, in use, the surge arrester resistor sheet grinding machine limiting device first places the surge arrester resistor sheet on top of the elastic diaphragm 31 and positions the resistor sheet between the fixed clamping plate 2 and the movable clamping plate 21. Then, the electric push rod 22 extends and drives the movable clamping plate 21 to move laterally. After moving, the movable clamping plate 21 can cooperate with the fixed clamping plate 2 to press and limit the resistor sheet in the limiting seat 1, so that the resistor sheet is not easy to be displaced during the subsequent grinding process, thereby ensuring the grinding accuracy and quality.

[0036] After grinding, the electric push rod 22 can be shortened to allow the movable clamping plate 21 to detach from one side of the resistor sheet. At this time, the ground resistor sheet can be removed. Then, the electric push rod 22 is shortened continuously. At this time, the movable clamping plate 21 will move towards the electric push rod 22 and push the U-shaped rod 32. The triangular plate 33 will move with the U-shaped rod 32, so that the trapezoidal block 3 can be lifted upward by the guide of the triangular plate 33. The upward-moving trapezoidal block 3 will lift the middle area of ​​the elastic diaphragm 31 upward, so that the elastic diaphragm 31 forms a cone shape. Then, by controlling the electric push rod 22 to extend and retract slightly, the elastic diaphragm 31 will collide repeatedly with the movable clamping plate 21 and other components. This will cause the debris on the elastic diaphragm 31 to move towards the bottom area of ​​the elastic diaphragm 31 under the vibration of the collision and its own gravity, thereby shaking off the debris on the cone-shaped elastic diaphragm 31 and quickly removing the debris in the resistor sheet placement area.

[0037] After the chip removal process, the electric push rod 22 is continuously extended, which allows the movable clamping plate 21 to disengage from the push plate 34. At this time, under the elastic force of the spring 35, the U-shaped rod 32 can be pushed into the limiting seat 1, so that the U-shaped rod 32 returns to its original position. At this time, the elastic diaphragm 31 and the trapezoidal block 3 lose pressure and will naturally fall back to their original positions. Then, another resistor sheet to be ground can be placed in the placement area of ​​the elastic diaphragm 31, thereby facilitating the replacement of the resistor sheet.

[0038] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
