Description

Technical Field

[0001] The present invention relates to the technical field of metal plate jigs, and specifically relates to a processing jig for metal plate production. Background Art

[0002] A metal plate is a thin, flat sheet formed from metal by industrial methods. Sheet metal is one of the basic forms used in metal processing. It can be cut and bent into various shapes. Countless daily necessities are made of metal plates. Metal plates are decorative plates with a metal material as the base material, such as aluminum and aluminum alloy base materials, steel plate base materials, stainless steel base materials, copper base materials, etc., and are processed through different processes on the surface, such as grinding, polishing, spraying, baking paint, transfer printing, etc.

[0003] In the prior art, due to the small thickness of thin metal plates, their bending stiffness is relatively low. When thin metal plates are processed such as grinding and polishing, they need to be clamped. However, common clamping only presses and clamps one point of the thin metal plate. Therefore, it may cause local or overall deformation of the metal plate during the clamping process, and may cause indentations or scratches during the clamping process, affecting the surface quality of the workpiece. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides a processing jig for metal plate production to solve the problems raised in the above background art.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] A processing jig for metal plate production, including a clamping table, a clamping plate is arranged on the top surface of the clamping table, a reinforcing column is fixedly installed on the top surface of the clamping plate, and mounting frames are respectively fixedly installed on both sides of the clamping table; a limiting mechanism for pressing the metal plate is arranged on one side of the mounting frame; a clamping assembly is arranged on both sides of the clamping table for grinding and clamping the metal plate. The clamping assembly includes: two support frames, the two support frames are respectively arranged on both sides of the clamping table, an operation plate is fixedly installed on the top surface of the support frame, sliding holes are respectively opened on the top surfaces of the support frame and the operation plate, a limiting groove is opened on one side inside the sliding hole, a moving hole is opened on one side of the operation plate, two sliders are movably sleeved inside the sliding hole, an operation column is fixedly installed on one side of the slider, the operation column is movably sleeved with the moving hole, a limiting block is fixedly installed on the other side of the slider, the limiting block is movably sleeved with the limiting groove, a fastening hole is opened on the top surface of the slider, threads are opened on the inner circumferential wall surface of the fastening hole, a fastening column is threadedly connected to the inner circumferential wall surface of the fastening hole, threads are opened on the outer circumferential wall surface of the fastening column, a pressing block is fixedly installed on the bottom surface of the fastening column, and a rubber block is fixedly installed on the bottom surface of the pressing block.

[0007] By adopting the above technical solution, through the provided clamping plate, when the staff polishes the side of the thin metal plate, first place the thin metal plate on the top surface of the clamping table, and pass the two sides of the thin metal plate through the interiors of the left and right support frames respectively. Then, the staff uses the limiting mechanism to move the clamping plate downward so that the clamping plate contacts the surface of the thin metal plate. At this time, the thin metal plate is between the clamping table and the clamping plate and is clamped by the clamping table and the clamping plate. Furthermore, the side to be polished is left outside the clamping table and is not between the clamping table and the clamping plate. Then, the side of the metal plate left outside the clamping table is sleeved into the interior of the support frame, and the support frame is moved close to the side of the metal plate to be polished. Subsequently, the staff drives the pressing block and the rubber block to rotate by rotating the fastening column, and moves the fastening column, the pressing block and the rubber block downward. Furthermore, the rubber block approaches the surface of the thin metal plate, and the fastening column is tightened to make the rubber block closely adhere to the thin metal plate, so that the thin metal plate can be clamped. Since the clamping plate clamps the thin metal plate over a large area and then cooperates with the support frame to clamp the side of the thin metal plate to be polished, a support point can be applied to the polished edge of the thin metal plate to prevent damage to the thin metal plate caused by vibration generated during the polishing of the side of the thin metal plate. By clamping the thin metal plate as a whole through the clamping plate, it is convenient to clamp the thin metal plate as a whole, preventing the situation where the surface of the thin metal plate is relatively soft and a single-point clamping causes uneven stress on the surface of the thin metal plate, resulting in bending or indentation, which is likely to cause local or overall deformation of the metal plate.

[0008] Preferably, the limiting mechanism includes: two fixing frames, the two fixing frames are respectively fixedly installed on one side of the two mounting frames, two support ribs are fixedly installed on one side of the mounting frame, the support ribs are fixedly installed with the fixing frames, a mounting block is fixedly installed on one side inside the fixing frame, a fixing groove is opened on the top surface of the mounting block, a hydraulic rod is fixedly sleeved on the inner circular wall surface of the fixing groove, two pushing columns are fixedly installed on the top surface of the telescopic rod of the hydraulic rod, a swinging hole is opened on one side of the pushing column, a stabilizing frame is fixedly installed on one side inside the fixing frame, rotating holes are respectively opened on both sides of the stabilizing frame, a lifting column is arranged on the top surface of the fixing frame, rotating columns are respectively fixedly installed on both sides of the lifting column, the rotating columns are movably sleeved with the rotating holes, swinging blocks are respectively fixedly installed on both sides of the lifting column, the swinging blocks are movably sleeved with the swinging holes, a connecting hole is opened on one side of the lifting column, a reserved hole is opened on one side of the fixing frame, a pressure column is arranged on the bottom surface of the lifting column, a U-shaped frame is fixedly installed on the top surface of the pressure column, a pulling column is fixedly installed inside the U-shaped frame, the pulling column is movably sleeved with the connecting hole, a first spring is movably sleeved on the outer circular wall surface of the pressure column, a moving hole is opened on the top surface of the mounting frame, the pressure column is movably sleeved with the moving hole, an extrusion plate is fixedly installed inside the mounting frame, a stabilizing hole is opened on the top surface of the extrusion plate, the stabilizing hole is movably sleeved with the pressure column, both ends of the first spring are respectively fixedly installed on the top surface of the extrusion plate and the inner top surface of the mounting frame, lifting blocks are respectively fixedly installed on both sides of the reinforcing column, the lifting blocks are movably sleeved with the mounting frame, and the lifting blocks are fixedly installed with the pressure column.

[0009] By adopting the above technical solution, through the arranged pressure column, when the staff places the thin metal plate on the top surface of the clamping table and clamps it with the clamping plate, by using the hydraulic rod, the movement of the telescopic rod of the hydraulic rod will drive the pushing column to move, and then the pushing column will push the lifting column to move. Then, under the push of the hydraulic rod and the pushing column, the lifting column will drive the rotating column and the swinging block to rotate. Subsequently, the end of the lifting column will tilt upwards, driving the pulling column, the U-shaped frame, the pressure column, the lifting block, the reinforcing column and the clamping plate to move upwards, and squeezing the first spring to contract. Thus, the clamping plate can be separated from the clamping table, increasing the distance between the clamping table and the clamping plate. Then, the thin metal plate is placed between the clamping table and the clamping plate. Subsequently, the telescopic rod of the hydraulic rod is driven to drive the pushing column to contract. Then, the pushing column, the lifting column, the U-shaped frame, the pressure column, the lifting block, the reinforcing column and the clamping plate can be reset, and the first spring rebounds. Thus, the clamping plate can be pressed on the top surface of the thin metal plate, facilitating large-area clamping of the thin metal plate.

[0010] Preferably, a plurality of strengthening blocks are fixedly installed on the top surface of the clamping plate, and a cutting groove is opened on the top surface of the reinforcing column.

[0011] By adopting the above technical solution, after the clamping plate is attached to the clamping table by the staff, the metal plate is placed on the top surfaces of the reinforcing columns and the reinforcing blocks, which is convenient for cutting the metal plate.

[0012] Preferably, stabilizing blocks are respectively and fixedly installed on both sides of the mounting frame, limiting plates are respectively and fixedly installed on both sides of the mounting frame, positioning holes are formed in the top surfaces of the limiting plates, an operating frame is fixedly installed on one side of each stabilizing block, a contraction hole is formed in the bottom surface of the operating frame, rotating blocks are respectively and fixedly installed on both sides of the operating frame, a movable column is movably sleeved on the inner circular wall surface of the contraction hole, a pulling hole is formed in the outer circular wall surface of the movable column, a second spring is movably sleeved on the outer circular wall surface of the movable column, an adjusting plate is arranged at the bottom of the movable column, a fixing block is fixedly installed on the bottom surface of the adjusting plate, two connecting plates are arranged on one side of the operating frame, two stabilizing columns are fixedly installed between the two connecting plates, a pushing frame is arranged on one side of the operating frame, mounting holes are respectively formed in both sides of the pushing frame, the two stabilizing columns are respectively movably sleeved in the mounting holes and the pulling holes, limiting holes are respectively formed in both sides of the pushing frame, the limiting holes are movably sleeved with the rotating blocks, and both ends of the second spring are fixedly installed on the adjusting plate and the limiting plate respectively.

[0013] By adopting the above technical solution, through the provided fixing block, when the staff places the metal plate on the surfaces of the reinforcing columns and the reinforcing blocks for cutting, first, the staff moves the pushing frame upward to drive the connecting plate to move, and then the connecting plate will drive the stabilizing column, the movable column, the adjusting plate and the fixing block to move upward and compress the second spring. Then, the staff places the metal plate on the top surfaces of the reinforcing blocks and the reinforcing columns. Subsequently, the staff pulls the pushing frame downward to drive the connecting plate, the mounting hole, the adjusting plate and the fixing block to reset, so as to facilitate pressing the fixing block on the top of the metal plate to clamp it for subsequent cutting.

[0014] Preferably, threads are formed on the outer circular wall surface of the movable column, an adjusting hole is formed in the top surface of the adjusting plate, the movable column is movably sleeved in the adjusting hole, and a nut is threadedly connected to the outer circular wall surface of the movable column.

[0015] By adopting the above technical solution, through the provided nut, when the staff clamps the metal plate to be cut, first, the nut is loosened, and then the adjusting plate is rotated to drive the fixing block to rotate until the fixing block rotates to the top surface of the clamping plate. Then, the nut is tightened to limit the adjusting plate, so as to facilitate adjusting the position of the fixing block.

[0016] Preferably, a guide post is fixedly installed inside the moving hole. A guide hole is opened on one side of the operating post. An installation groove is opened on the inner circumferential wall surface of the guide hole. A magnet is fixedly sleeved on the inner circumferential wall surface of the installation groove. The guide hole is movably sleeved with the guide post.

[0017] By adopting the above technical solution, through the arranged magnet, since the guide post is made of iron, when the staff moves the slider to drive the fastening post, the pressing block and the rubber block to move, the positions of the two sliders can be changed, so that the two sliders and the operating post move on the outer circumferential wall surface of the guide post. Since the magnet and the guide post are adsorbed together, there will be resistance when the slider and the operating post move. When the slider stops moving, the magnet and the guide post will be adsorbed together, thus facilitating the adjustment of the positions of the two sliders to clamp thin metal plates with different widths.

[0018] Preferably, a moving block is fixedly installed on the bottom surface of the support frame. Clamping blocks are respectively fixedly installed on both sides of the moving block. Moving grooves are respectively opened on both sides of the clamping table. A plurality of clamping grooves are respectively opened on both sides inside the moving grooves. The moving block is movably sleeved with the moving groove. The clamping groove is movably sleeved with the clamping block.

[0019] By adopting the above technical solution, through the arranged moving block, when the staff pulls the support frame to drive the moving block and the clamping block to move, the moving block can be moved out of the inside of the moving groove, and the support frame can be moved away from one side of the clamping table, thus facilitating the adjustment of the clamping and supporting points of the support frame for the grinding position on the side of the metal plate.

[0020] Preferably, a rubber pad is fixedly installed on the bottom surface of the clamping plate.

[0021] By adopting the above technical solution, it is to increase the friction force when the clamping plate clamps.

[0022] In summary, the present invention mainly has the following beneficial effects:

[0023] By the mutual cooperation of the arranged clamping table, clamping plate, support frame, operating plate, sliding hole, limiting groove, moving hole, slider, operating post, fastening post, pressing block, rubber block, fastening hole and limiting block, the thin metal plate can be clamped. The support frame clamps on the side of the thin metal plate that needs to be ground, and a support point can be applied to the grinding edge of the thin metal plate to prevent damage to the thin metal plate caused by vibration generated during the grinding of the side of the thin metal plate. By clamping the whole thin metal plate through the clamping plate, it is convenient to clamp the whole thin metal plate, preventing the situation that the surface of the thin metal plate is soft and the clamping at a single point causes uneven force on the surface of the thin metal plate, resulting in bending or indentation, which is likely to cause local or overall deformation of the metal plate.

A clamping plate 2 is provided on the top surface of the clamping table 1. A reinforcing column 38 is fixedly installed on the top surface of the clamping plate 2. Installation frames 15 are respectively fixedly installed on both sides of the clamping table 1. A limiting mechanism for pressing the metal plate is provided on one side of the installation frame 15. Clamping components are provided on both sides of the clamping table 1 for grinding and clamping the metal plate. The clamping components include two support frames 3. The two support frames 3 are respectively arranged on both sides of the clamping table 1. An operation plate 4 is fixedly installed on the top surface of the support frame 3. Sliding holes 5 are respectively opened on the top surfaces of the support frame 3 and the operation plate 4. A limiting groove 6 is opened on one side inside the sliding hole 5. A moving hole 7 is opened on one side of the operation plate 4. Two sliders 8 are movably sleeved inside the sliding hole 5. An operation column 9 is fixedly installed on one side of the slider 8. The operation column 9 is movably sleeved with the moving hole 7. A limiting block 14 is fixedly installed on the other side of the slider 8. The limiting block 14 is movably sleeved with the limiting groove 6. A fastening hole 13 is opened on the top surface of the slider 8. Threads are provided on the inner circular wall surface of the fastening hole 13. A fastening column 10 is threadedly connected to the inner circular wall surface of the fastening hole 13. Threads are provided on the outer circular wall surface of the fastening column 10. A pressing block 11 is fixedly installed on the bottom surface of the fastening column 10. A rubber block 12 is fixedly installed on the bottom surface of the pressing block 11. By providing the clamping plate 2, when the staff grinds the side of a thin metal plate, first place the thin metal plate on the top surface of the clamping table 1, and pass the two sides of the thin metal plate through the interiors of the left and right support frames 3 respectively. Then the staff uses the limiting mechanism to move the clamping plate 2 downward so that the clamping plate 2 contacts the surface of the thin metal plate. At this time, the thin metal plate is between the clamping table 1 and the clamping plate 2 and is clamped by the clamping table 1 and the clamping plate 2. Furthermore, the side to be ground is left outside the clamping table 1 and is not between the clamping table 1 and the clamping plate 2. Then, the side of the metal plate left outside the clamping table 1 is sleeved into the interior of the support frame 3 to make the support frame 3 close to the side of the metal plate to be ground. Subsequently, the staff drives the pressing block 11 and the rubber block 12 to rotate by rotating the fastening column 10, and makes the fastening column 10, the pressing block 11 and the rubber block 12 move downward. Furthermore, the rubber block 12 approaches the surface of the thin metal plate, and the fastening column 10 is tightened to make the rubber block 12 closely adhere to the thin metal plate, so that the thin metal plate can be clamped. Since the clamping plate 2 clamps the thin metal plate over a large area, and then cooperates with the support frame 3 to clamp the side of the thin metal plate to be ground, a support point can be applied to the grinding edge of the thin metal plate to prevent damage to the thin metal plate caused by vibration generated during the grinding of the side of the thin metal plate. By clamping the thin metal plate by the clamping plate 2 over the whole, it is convenient to clamp the thin metal plate as a whole, preventing the situation that the surface of the thin metal plate is soft and single-point clamping causes uneven stress on the surface of the thin metal plate, resulting in bending or indentation, which is likely to cause local or overall deformation of the metal plate.

[0043] Working principle: Please refer to Figures 1 - 9As shown in the figure, through the set clamping plate 2, when the staff grinds the side of the thin metal plate, first place the thin metal plate on the top surface of the clamping table 1, and pass the two sides of the thin metal plate through the inside of the left and right support frames 3 respectively. Then the staff uses the limiting mechanism to move the clamping plate 2 downward so that the clamping plate 2 contacts the surface of the thin metal plate. At this time, the thin metal plate is between the clamping table 1 and the clamping plate 2 and is clamped by the clamping table 1 and the clamping plate 2. Furthermore, the side to be ground is left outside the clamping table 1 and is not between the clamping table 1 and the clamping plate 2. Then the side of the metal plate left outside the clamping table 1 is sleeved into the inside of the support frame 3 to make the support frame 3 close to the side of the metal plate to be ground. Subsequently, the staff drives the pressing block 11 and the rubber block 12 to rotate by rotating the fastening column 10, and moves the fastening column 10, the pressing block 11 and the rubber block 12 downward. Furthermore, the rubber block 12 approaches the surface of the thin metal plate, tightens the fastening column 10 to make the rubber block 12 closely adhere to the thin metal plate, so that the thin metal plate can be clamped. Since the clamping plate 2 clamps the thin metal plate over a large area and then cooperates with the support frame 3 to clamp the side of the thin metal plate to be ground, a support point can be applied to the grinding edge of the thin metal plate to prevent damage to the thin metal plate caused by the vibration generated during the grinding of the side of the thin metal plate. By clamping the thin metal plate as a whole through the clamping plate 2, it is convenient to clamp the thin metal plate as a whole, preventing uneven force on the surface of the thin metal plate caused by clamping at a single point on the relatively soft surface of the thin metal plate, which may easily lead to local or overall deformation of the metal plate.

[0044] Through the set pressure column 30, when the staff places the thin metal plate on the top surface of the clamping table 1 and uses the clamping plate 2 for clamping, by using the hydraulic rod 22, the movement of the telescopic rod of the hydraulic rod 22 will drive the push column 23 to move. Furthermore, the push column 23 will push the lifting column 25 to move. Then, under the push of the hydraulic rod 22 and the push column 23, the lifting column 25 will drive the rotating column 26 and the swing block 27 to rotate. Subsequently, the end of the lifting column 25 will tilt upward, driving the pulling column's 34, U-shaped frame 33, pressure column 30, lifting block 39, reinforcement column 38 and clamping plate 2 to move upward, and squeezing the first spring 32 to contract. Thus, the clamping plate 2 can be separated from the clamping table 1 to increase the distance between the clamping table 1 and the clamping plate 2. Then the thin metal plate is placed between the clamping table 1 and the clamping plate 2. Subsequently, let the telescopic rod of the hydraulic rod 22 drive the push column 23 to contract. Furthermore, the push column 23, the lifting column 25, the U-shaped frame 33, the pressure column 30, the lifting block 39, the reinforcement column 38 and the clamping plate 2 can be reset, and the first spring 32 can rebound. Thus, the clamping plate 2 can be pressed on the top surface of the thin metal plate, facilitating large-area clamping of the thin metal plate.

[0045] After the clamping plate 2 is attached to the clamping table 1 by the staff, the metal plate is placed on the top surfaces of the reinforcing columns 38 and the reinforcing blocks 40, facilitating the cutting of the metal plate.

[0046] With the fixed block 54 provided, when the staff places the metal plate on the surfaces of the reinforcing columns 38 and the reinforcing blocks 40 for cutting, first, the staff moves the push frame 57 upward to drive the connecting plate 55 to move. Further, the connecting plate 55 will drive the stabilizing column 56, the movable column 48, the adjusting plate 51, and the fixed block 54 to move upward and compress the second spring 50. Then, the staff places the metal plate on the top surfaces of the reinforcing blocks 40 and the reinforcing columns 38. Subsequently, the staff pulls the push frame 57 downward to drive the connecting plate 55, the mounting hole 58, the adjusting plate 51, and the fixed block 54 to reset, so as to facilitate the fixed block 54 pressing on the top of the metal plate to clamp it for subsequent cutting.

The scope of the present invention is defined by the appended claims and their equivalents.
