A clamping device for processing carbon products

Abstract

This utility model discloses a clamping device for processing carbon products, relating to the technical field. The utility model includes a processing table and a clamping mechanism positioned above the processing table. Specifically, the clamping mechanism involves retracting an electric push rod, causing a round rod to move downwards. This downward movement pushes a convex plate, causing an eccentric block to rotate counterclockwise around a pivot axis. The spiral spring is compressed. When the bottoms of both eccentric blocks contact the tops of their corresponding main plates, the material is fixed to the processing table surface. As the main plates move downwards, their bottom rubber blocks deform under pressure, preventing direct contact between the main plates and the material and increasing friction. After processing, the electric push rod extends, causing the round rod to move upwards. This stops compressing the convex plate, and the spiral spring, using its own elasticity, drives the eccentric blocks to rotate clockwise to reset, allowing the material to be removed. This design allows for simultaneous clamping and fixing of both sides of the material, resulting in more even pressure on the material.

Description

Technical Field

[0001] This utility model belongs to the field of carbon product processing technology, and in particular relates to a clamping device for carbon product processing. Background Technology

[0002] Clamping devices used for carbon product processing are specialized mechanical devices designed specifically for carbon products (such as carbon plates) in the processing stages (including cutting, grinding, drilling, pre- and post-calcination treatment or finishing, etc.). They are widely used in multiple stages of carbon product processing, which are characterized by high hardness, high brittleness, and low tensile strength.

[0003] Traditionally, when clamping carbon products, clamping plates are installed on both sides of the carbon product, and then the bolts are turned to make the clamping plates contact the carbon product, thus completing the fixation. The clamping plate on the other side is fixed in the same way. Although this method can fix the carbon product well, the separate clamping and fixing method is very easy to cause uneven clamping force between the two clamping plates, which will lead to excessive local pressure on the carbon product, resulting in damage and material loss. Therefore, we propose the following. Utility Model Content

[0004] The purpose of this invention is to provide a clamping device for processing carbon products. Specifically, the clamping mechanism involves retracting an electric push rod, causing a round rod to move downwards. This downward movement pushes a convex plate, causing an eccentric block to rotate counter-clockwise around a pivot axis. The spiral spring is compressed. When the bottoms of both eccentric blocks contact the tops of their corresponding main plates, the material is fixed to the processing table surface. As the main plates move downwards, their bottom rubber blocks deform under pressure, preventing direct contact between the main plates and the material and increasing friction. After processing, the electric push rod extends, causing the round rod to move upwards. This stops compressing the convex plate, and the spiral spring, using its own elasticity, drives the eccentric blocks to rotate clockwise to reset, allowing the material to be removed. This design allows for simultaneous clamping and fixing of both sides of the material, resulting in more even pressure on the material. It solves the problem that existing clamping methods often use clamping plates and bolts to fix both sides of the carbon product, but this method easily leads to uneven clamping force on both sides of the material, which can easily damage the material.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a clamping device for processing carbon products, comprising: a processing table, two main plates disposed above the processing table, two sliding blocks internally fitted with sliding limit mechanisms on the main plates, and auxiliary plates fixedly connected to the opposite sides of the two sliding blocks; a clamping mechanism disposed above the processing table for fixing materials, the clamping mechanism including an eccentric block, a rotating shaft fixedly connected to the opposite side of the eccentric block away from the processing table, a protruding plate fixedly connected to the outer surface of the eccentric block; a horizontal plate disposed inside the processing table, with two vertical rods fixedly connected to the top of the horizontal plate; and an adjusting mechanism disposed inside the sliding blocks for moving the auxiliary plates; the processing table having a hollow interior, the two vertical rods being symmetrically arranged, and corrugated rubber pads affixed to the bottom of the main plates and the two auxiliary plates to prevent direct hard contact between the main plates and the materials, thus preventing damage, and also to increase friction for a more stable clamping.

[0007] Furthermore, the clamping mechanism includes two support plates fixedly connected to the top of the processing table, a support frame fixedly connected to the top of the support plates, and two limiting posts fixedly connected to the top of the main plate. Both limiting posts are slidably limited in cooperation with the support frame. An anti-detachment ring is fixedly connected to the top of the limiting post. The anti-detachment ring at the top of the limiting post is used to prevent the limiting post from detaching from the support frame. The support frame is C-shaped.

[0008] Furthermore, the bottom of the inner wall of the motherboard is provided with several card slots, and the left and right sides of the top of the motherboard are provided with receiving slots; the card slots are V-shaped and the several card slots are equally spaced.

[0009] Furthermore, a circular tube is fixedly connected to the inner side of the support frame, the rotating shaft is rotatably connected to the circular tube, a spiral spring is fixedly connected to the outer surface of the rotating shaft, and the other end of the spiral spring is fixedly connected to the inner wall of the circular tube; two anti-displacement rings are fixedly connected to the outer surface of the rotating shaft, and the two anti-displacement rings on the outer surface of the rotating shaft are respectively in contact with the left and right sides of the circular tube on their respective sides.

[0010] Furthermore, an electric push rod is fixedly connected to the bottom of the inner wall of the processing table, the top output end of the electric push rod is fixedly connected to the bottom of the horizontal plate, both vertical rods are slidably limited to the processing table, and a round rod is fixedly connected to the side of the two vertical rods that are close to each other; the outer surface of the round rod is in contact with the top of the convex plate.

[0011] Furthermore, a fixed tube is fixedly connected to the top of the movable block, and a bolt is provided inside the fixed tube. The fixed tube is slidably limited to the receiving groove. A threaded groove is provided on the inner wall of the fixed tube, and the bolt is threadedly connected to the threaded groove on the inner wall of the fixed tube. When both sub-plates are in contact with the main plate, the fixed tube will enter the receiving groove, so that the sub-plates can smoothly contact the main plate.

[0012] Furthermore, the movable block has a movable groove inside, and a movable plate is slidably limited to the inner wall of the movable groove. An insert block is slidably limited to the movable block inside. Limiting blocks are fixedly connected to both the front and back of the insert block. The movable block has two limiting grooves inside, and the limiting blocks slidably limit to the limiting grooves. The insert block is inserted into the slot. The movable plate has an inclined surface on the side away from the motherboard. The bottom of the limiting block is V-shaped. The insert block has an inclined surface on the side away from the motherboard. The bottom of the bolt is spherical, which can better push the movable plate away from the inclined surface on the side away from the motherboard.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model features a clamping mechanism. Specifically, the electric push rod retracts, causing the round rod to move downwards. This downward movement pushes the convex plate, causing the eccentric block to rotate counterclockwise around the axis of rotation. The spiral spring is compressed. When the bottoms of both eccentric blocks contact the tops of their corresponding main plates, the material is fixed on the processing table surface. As the main plate moves downwards, its bottom rubber block is compressed and deformed, preventing the main plate from directly contacting the material and increasing friction. After processing, the electric push rod extends, causing the round rod to move upwards. It no longer compresses the convex plate, and the spiral spring, using its own elasticity, drives the eccentric block to rotate clockwise to reset, allowing the material to be removed. This design can clamp and fix both sides of the material simultaneously, resulting in more even pressure on the material.

[0015] 2. This utility model features an adjustment mechanism. Specifically, rotating the bolt counterclockwise moves the bolt upward, causing two springs to pull the moving plate away from the main board. The bottom of the moving plate disengages from the top of the insert block. At this point, the secondary plate can be pulled left or right. As the secondary plate moves, the slot presses against the inclined surface at the bottom of the insert block, pushing the insert block upward. After adjustment, the insert block falls into the slot under its own weight. Then, rotating the bolt clockwise moves the bolt downward, pressing against the inclined surface of the moving plate and pushing the moving plate closer to the main board. The bottom of the moving plate contacts the top of the limiting block, restricting the upward movement of the insert block. This design allows for flexible adjustment of the distance between the main board and the two secondary plates, enabling clamping of materials of different lengths and improving processing efficiency.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-7As shown, this utility model is a clamping device for processing carbon products, including a processing table 1. Two main plates 31 are arranged above the processing table 1. Two moving blocks 321 are slidably limited inside the main plates 31. A secondary plate 32 is fixedly connected to the side of each moving block 321 that is far away from each other. It also includes: a clamping mechanism 2, which is arranged above the processing table 1 and is used to fix the material. The clamping mechanism 2 includes an eccentric block 23. A rotating shaft 231 is fixedly connected to the side of the eccentric block 23 that is far away from the processing table 1. A protruding plate 234 is fixedly connected to the outer surface of the eccentric block 23. A horizontal plate 241 is arranged inside the processing table 1. Two vertical rods 242 are fixedly connected to the top of the horizontal plate 241. An adjusting mechanism 3 is arranged inside the moving blocks 321 and is used to move the secondary plate 32. The processing table 1 has a cavity inside, and the two vertical rods 242 are symmetrically arranged. The clamping mechanism 2 includes two support plates 21 fixedly connected to the top of the processing table 1. A support frame 22 is fixedly connected to the top of the support plates 21. Two limiting posts 221 are fixedly connected to the top of the main plate 31. Both limiting posts 221 are slidably limited and cooperate with the support frame 22. An anti-detachment ring is fixedly connected to the top of the limiting post 221. The anti-detachment ring at the top of the limiting post 221 is used to prevent the limiting post 221 from detaching from the support frame 22. The support frame 22 is C-shaped. Several slots 311 are opened at the bottom of the inner wall of the main plate 31. Receiving slots 312 are opened on the left and right sides of the top of the main plate 31. The slots 311 are V-shaped and the slots 311 are evenly spaced. A circular tube 232 is fixedly connected to the inner side of the support frame 22. A rotating shaft 231 is rotatably connected to the circular tube 232. A spiral spring 233 is fixedly connected to the outer surface of the rotating shaft 231. The other end of the spiral spring 233 is fixedly connected to the inner wall of the circular tube 232. Two anti-displacement rings are fixedly connected to the outer surface of the rotating shaft 231. The two anti-displacement rings on the outer surface of the rotating shaft 231 are in contact with the left and right sides of the circular tube 232, respectively. An electric push rod 24 is fixedly connected to the bottom of the inner wall of the processing table 1. The top output end of the electric push rod 24 is fixedly connected to the bottom of the horizontal plate 241. Two vertical rods 242 are both slidably limited to the processing table 1. A round rod 243 is fixedly connected to the side of the two vertical rods 242 that are close to each other. When the electric push rod 24 is activated, it retracts, causing the round rod 243 to move down. Its downward movement pushes the convex plate 234, causing the eccentric block 23 to rotate counterclockwise around the axis of the rotating shaft 231. The spiral spring 233 is compressed. When the bottom of the two eccentric blocks 23 are in contact with the top of the corresponding main plate 31, When the material is fixed on the surface of the processing table 1, the bottom rubber block of the main board 31 is squeezed and deformed when the main board 31 moves down, which avoids the main board 31 directly contacting the material and increases the friction. After processing is completed, the electric push rod 24 is activated to extend, so that the round rod 243 moves up and no longer squeezes the convex plate 234. The worm spring 233 drives the eccentric block 23 to rotate clockwise to reset by its own elastic force, so that the material can be removed. This setting can clamp and fix both sides of the material at the same time, so that the pressure on the material is more uniform. The outer surface of the round rod 243 contacts the top of the convex plate 234.

[0029] The top of the movable block 321 is fixedly connected to a fixed tube 322, and a bolt 323 is provided inside the fixed tube 322. The fixed tube 322 is slidably limited to the receiving groove 312. The inner wall of the fixed tube 322 is provided with a threaded groove, and the bolt 323 is threadedly connected to the threaded groove on the inner wall of the fixed tube 322. The movable block 321 has a movable groove 33 inside, and a movable plate 331 is slidably and limitly fitted inside the movable groove 33. An insert block 34 is slidably and limitly fitted inside the movable block 321. Limit blocks 341 are fixedly connected to the front and back of the insert block 34. Two limit grooves 342 are opened inside the movable block 321, and the limit blocks 341 and limit grooves 342 are slidably and limitly fitted. The insert block 34 is inserted into the slot 311. Rotating the bolt 323 counterclockwise causes it to move upwards. The two springs 332, by their own elastic force, pull the movable plate 331 to move away from the main plate 31. The bottom of the movable plate 331 disengages from the top of the insert block 34. At this time, the sub-plate 32 can be pulled left and right. When the sub-plate 32 moves, the slot 311 presses against the insert block. The bottom slope of block 34 pushes the insert block 34 upward. After adjustment, the insert block 34 falls into the slot 311 by its own weight. Then, the bolt 323 is rotated clockwise to move it downward. When the bolt 323 moves downward, it presses the slope of the moving plate 331, pushing the moving plate 331 to move closer to the main plate 31. The bottom of the moving plate 331 contacts the top of the limiting block 341, restricting the upward movement of the insert block 34. This setting can flexibly adjust the distance between the main plate 31 and the two sub-plates 32, and can clamp materials of different lengths to improve processing efficiency. The side of the moving plate 331 away from the main plate 31 is provided with a slope, the bottom of the limiting block 341 is V-shaped, and the side of the insert block 34 away from the main plate 31 is provided with a slope.

[0030] A specific application of this embodiment is as follows: In use, the material is placed on the top of the processing table 1, and then the electric push rod 24 is activated to retract, causing the horizontal plate 241 and the two vertical rods 242 to move downwards together. At the same time, the vertical rods 242 also cause the round rod 243 to move downwards. When the round rod 243 moves downwards, it pushes the convex plate 234 downwards, causing the eccentric block 23 to rotate counterclockwise around the axis of the rotating shaft 231. At this time, the spiral spring 233 is compressed. When the bottom of both eccentric blocks 23 contacts the top of the corresponding main plate 31, the material is fixed on the processing table 1. When the main board 31 moves down, the rubber block at its bottom will be squeezed and deformed to prevent the main board 31 from directly contacting the material. The rubber block can also increase friction and make the fixation more stable. Then processing can be carried out. After processing is completed, the electric push rod 24 is activated to extend, so that the horizontal plate 241 and the two vertical rods 242 move up. At this time, the round rod 243 no longer squeezes the convex plate 234. The spiral spring 233 will drive the eccentric block 23 to rotate clockwise and reset through its own elasticity. At this time, the two main boards 31 are no longer in contact with the material, and the material can be removed.

[0031] When the material dimensions are different, the bolt 323 can be rotated counterclockwise to move it upward. At this time, the bottom of the bolt 323 is no longer in contact with the moving plate 331. The two springs 332 pull the moving plate 331 away from the main plate 31 through their own elastic force. At this time, the bottom of the moving plate 331 is no longer in contact with the top of the insert block 34. The sub-plate 32 can then be pulled left or right. When the sub-plate 32 moves, the slot 311 will press against the inclined surface at the bottom of the insert block 34, thereby pushing the insert block 34 upward. When the sub-plate 32 moves to the appropriate position, it stops moving. The insert block 34 will fall into the slot 311 under its own weight. At this time, the bolt 323 can be rotated clockwise to move it downward. When the bolt 323 moves downward, it will press against the moving plate 331. The inclined surface of the movable plate 331 is pushed to move it closer to the main plate 31. At this time, the bottom of the movable plate 331 will contact the top of the limit block 341, preventing it from moving upward. When the movable plate 331 moves, it will pull the two springs 332 to stretch. When the movable block 321 is adjusted, the insert 34 may not fall into the slot 311. At this time, the movable block 321 can be moved slightly to the left or right. If a click is heard, it indicates that the insert 34 has been inserted into the slot 311. Alternatively, the bolt 323 can be turned clockwise. If the bolt 323 cannot be moved down, it indicates that the insert 34 has not entered the slot 311. At this time, the insert 34 can be put into the slot 311 by the above method. The other sub-plates 32 can be adjusted in the same way.
