Description

Technical Field

[0001] The utility model relates to the technical field of profile processing, in particular to a clamping device for punching metal plates. Background Technique

[0002] In the prior art, the Chinese patent document with the patent number CN216606860U proposed a fixing device for punching metal plates. By setting friction-increasing blocks and friction-increasing layers made of rubber material, since the rubber material has a large friction coefficient, using them as friction-increasing blocks and friction-increasing layers can increase the contact area between the top block and the clamping block and the metal plate, thereby increasing the friction force between the two and making the fixation of the metal plate more firm. However, the purely mechanical control fixture used cannot well apply appropriate pressure clamping according to different material properties, which may cause damage to the plate parts and has poor applicability. Therefore, by the method of manually controlling the plate fixture, it is better to judge the clamping force required by the fixture for the plate. The present application discloses a clamping device for punching metal plates to solve the problem of damage to plate parts with different material properties during fixture clamping and make it more labor-saving for workers to operate the fixture to clamp through the lever principle. Content of the Utility Model

[0003] In view of this, the purpose of the present utility model is to propose a clamping device for punching metal plates to solve the problem of damage to plate parts with different material properties during fixture clamping and make it more labor-saving for workers to operate the fixture to clamp through the lever principle.

[0004] Based on the above purpose, the present utility model provides a clamping device for punching metal plates, including a loading block. A through rectangular groove is opened at the lower end of the loading block, and a plate can be placed between the grooves. An anti-slip pad is installed at the bottom of the groove. A through rectangular groove inside the loading block is in a hollow shape, and a sliding extrusion assembly is installed inside the hollow groove of the loading block. The sliding extrusion assembly includes an upper ladder block and a lower ladder block. A power assembly for pushing the sliding extrusion assembly to move is also installed inside the loading block. The power assembly includes a support shaft and an extrusion rod. A support frame is installed at the upper end of the loading block, and a through threaded groove is opened at the top of the support frame.

[0005] Preferably, a threaded rod is installed in the threaded groove of the support frame. A limit ring is installed at the top of the threaded rod, and a through groove is opened at the top of the threaded rod. A handrail rod is sleeved and installed in the groove.

[0006] Preferably, the bottom corners of the threaded rod are semi-circular. The lower end of the threaded rod abuts against the extrusion rod. The shape of the extrusion rod is sickle-shaped, and a through circular groove is opened at the front corner of the extrusion rod.

[0007] Preferably, the support shaft is rotatably installed in the circular groove of the extrusion rod. The two ends of the support shaft are respectively fixedly installed on the inner wall of the hollow part of the loading block. The long side of the extrusion rod abuts against the bottom of the threaded rod, and the short side of the extrusion rod abuts against the top surface of the upper ladder block.

[0008] Preferably, the inclined surface of the upper ladder block fits with the inclined surface of the lower ladder block, and the loading block and the lower ladder block are connected by a mortise and tenon structure. The loading block and the lower ladder block can slide through the guiding groove of the mortise and tenon structure.

[0009] Preferably, a through circular groove is formed on the tenon of the lower ladder block's mortise and tenon structure. A limiting block is installed at the bottom of the groove of the loading block's mortise and tenon structure. A vertical guiding rod is installed on the limiting block, and a vertical spring is sleeved on the vertical guiding rod.

[0010] Preferably, the diameter of the vertical guiding rod is smaller than the diameter of the circular groove formed on the tenon of the lower ladder block's mortise and tenon structure.

[0011] The beneficial effects of the present utility model: When using the fixture, hold the handrail rod and rotate it to make the threaded rod rotate clockwise, push down the long side of the extrusion rod, so that the extrusion rod rotates around the support shaft. At the same time, the front part of the extrusion rod abuts against the upper ladder block and moves downward. At this time, the inclined surface of the upper ladder block will push the inclined surface of the lower body block, so that the lower body block moves downward along the guiding groove. The lower end of the lower body block abuts against the plate member for clamping. Because of the special shape of the extrusion rod and the position of the support column, the force required to rotate the handrail rod is very small. Because the contact area between the lower body block and the plate member is large, the plate member will not be easily damaged during the clamping process. Hold the handrail rod and rotate it to make the threaded rod rotate clockwise, push down the long side of the extrusion rod, so that the extrusion rod rotates around the support shaft. At the same time, the front part of the extrusion rod abuts against the upper ladder block and moves downward. At this time, the inclined surface of the upper ladder block will push the inclined surface of the lower body block, so that the lower body block moves downward along the guiding groove. The lower end of the lower body block abuts against the plate member for clamping. Because of the special shape of the extrusion rod and the position of the support column, the force required to rotate the handrail rod is very small. Because the contact area between the lower body block and the plate member is large, the plate member will not be easily damaged during the clamping process. The top surface of the plate member to be clamped abuts against the bottom end of the lower body block, and the bottom surface of the plate member abuts against the surface of the anti-slip pad. Because the surface of the anti-slip pad is provided with grooves to increase the friction force, it is not easy to slide, and the anti-slip pad is made of rubber material and will not cause damage to the surface of the clamped plate member. Therefore, the clamped plate member can be better protected. Description of the Drawings

The terms such as "connected" or "coupled" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. The terms such as "upper", "lower", "left", "right" are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0020] The present invention provides as Figures 1 to 3A fixture device for punching metal plates is shown, including a loading block 1. A through rectangular groove is opened at the lower end of the loading block 1, and a plate 10 can be placed between the grooves. It is characterized in that: an anti-slip pad 11 is installed at the bottom of the groove. A through rectangular groove inside the loading block 1 is in a hollow shape, and a sliding extrusion component is installed inside the hollow groove of the loading block 1. The sliding extrusion component includes an upper trapezoidal block 8 and a lower trapezoidal block 9. A power component for pushing the sliding extrusion component to move is also installed inside the loading block 1. The power component includes a support shaft 6 and an extrusion rod 7. A support frame 2 is installed at the upper end of the loading block 1. A through threaded groove is opened at the top of the support frame 2. When the plate to be clamped is placed in the fixture, the top surface of the plate to be clamped abuts against the bottom end of the lower body block 9, and the bottom surface of the plate abuts against the surface of the anti-slip pad 11. Because the surface of the anti-slip pad 11 is provided with grooves to increase the friction force, making it not easy to slide, and the anti-slip pad 11 is made of rubber material and will not cause damage to the surface of the clamped plate, so the clamped plate can be better protected.

[0021] Further, in this example, as Figures 1 to 3 shown, a threaded rod 3 is installed in the threaded groove of the support frame 2. A limit ring 4 is installed at the top of the threaded rod 3, and a through groove is opened at the top of the threaded rod 3. A handrail rod 5 is sleeved and installed in the groove. The bottom corner of the threaded rod 3 is semi-circular. The lower end of the threaded rod 3 abuts against the extrusion rod 7. The shape of the extrusion rod 7 is sickle-shaped. A through circular groove is opened at the front corner of the extrusion rod 7. A support shaft 6 is rotatably installed in the circular groove of the extrusion rod 7. Both ends of the support shaft 6 are fixedly installed on the inner wall of the hollow part inside the loading block 1. The long side of the extrusion rod 7 abuts against the bottom of the threaded rod 3, and the short side of the extrusion rod 7 abuts against the top surface of the upper trapezoidal block 8. When using the fixture, hold the handrail rod 5 with your hand and rotate it to make the threaded rod 3 rotate clockwise, pushing down the long side of the extrusion rod 7, so that the extrusion rod 7 rotates around the support shaft 6. At the same time, the front part of the extrusion rod 7 abuts against the upper trapezoidal block 8 and moves downward. At this time, the inclined surface of the upper trapezoidal block 8 will push the inclined surface of the lower body block 9, making the lower body block 9 move downward along the guide groove. The lower end of the lower body block 9 abuts against the plate to clamp it. Because of the special shape of the extrusion rod 7 and the position of the support column 6, the force required to rotate the handrail rod 5 is very small. Because the contact area between the lower body block 9 and the plate is large, the plate will not be easily damaged during the clamping process.

[0022] Further, in this example, as Figure 3As shown, the inclined surface of the upper ladder block 8 fits with the inclined surface of the lower ladder block 9, and the loading block 1 is connected to the lower ladder block 9 through a mortise and tenon structure. The loading block 1 and the lower ladder block 9 can slide through the guide groove of the mortise and tenon structure. A through circular groove is provided on the mortise and tenon structure protrusion of the lower ladder block 9. A limit block is installed at the bottom of the mortise and tenon structure groove of the loading block 1. A vertical guide rod 12 is installed on the limit block, and a vertical spring 13 is installed on the vertical guide rod 12. The diameter of the vertical guide rod 12 is smaller than the diameter of the mortise and tenon structure protrusion of the lower ladder block 9. The diameter of the circular groove, when the upper ladder block 8 and the lower body block 9 move downward, the lower body block 9 will slide in the guide groove of the mortise and tenon structure. At the same time, the bottom surface of the circular groove opened on the lower body block 9 will resist the vertical spring 13 set on the vertical guide rod 12 and move downward. When clamping is not needed, hold the handrail bar 5 to make the threaded rod 3 rotate counterclockwise, and the extrusion rod 7 will be reset accordingly. At this time, the lower body block 9 will move upward under the reaction force of the vertical spring 13, and at the same time push the upper ladder block 9 to reset it to its initial position.
