Description

Technical Field

[0001] The utility model relates to the technical field of riveting machine clamps, in particular to a riveting machine and a clamp thereof. Background Art

[0002] A riveting machine is a device used to securely install rivets, while a hydraulic riveting machine is a riveting machine that uses hydraulics to push the machine forward. It is widely used in industries such as automobiles, ships, bridges, and construction. It is characterized by high riveting force, high riveting efficiency, low vibration, low noise, and reliable riveting operation quality. It can also reduce the labor intensity of workers.

[0003] Patent document CN219274368U discloses a hydraulic riveting machine. Pulling a baffle causes the baffle to move a pull rod to one side, compressing a spring. A steel plate is then placed on a placement plate. Release the baffle, causing the spring to push the pull rod to one side, returning it to its original position and causing the baffle to cling to one side of the steel plate, thereby securing the steel plate on the placement plate. In implementing this technical solution, the inventors discovered that the prior art has at least the following problems:

[0004] When the above device is actually used, the placement plate is inconvenient for fixing cylindrical or bar workpieces, and it has certain limitations. At the same time, the baffle only relies on the clamping force of the spring to clamp the workpiece. Due to the lack of an active clamping drive source, the spring force increases with the increase in compression. The clamping effect is different for workpieces of different sizes to be clamped, and it is not easy to adjust according to the size of the workpiece. The clamping force is not stable enough and the use effect is poor.

[0028] The driving assembly 3 includes a screw rod 31 rotatably arranged inside the movable base 1, an arc-shaped splint 32 is rotatably arranged at one end of the screw rod 31, a semicircular groove 33 is provided in the middle of the fixed plate 4, and a placement groove 34 is provided below the semicircular groove 33 on the movable base 1. A guide rod 35 is fixedly connected to one side of the arc-shaped splint 32, and a guide groove 36 is provided inside the movable base 1 for use with the guide rod 35.

[0029] It should be noted that: the steel plate workpiece is placed between the fixed plate 4 and the clamping plate 5 on the top of the placing plate 2, and the clamping plate 5 moves on the placing plate 2 to clamp and fix the workpiece. The bar can be placed in the placing groove 34 in the movable seat 1 through the semicircular groove 33 in the middle of the fixed plate 4, and the arc clamping plate 32 is driven to move in the placing groove 34 by rotating the screw rod 31 to clamp and fix the bar. When the arc clamping plate 32 moves, the guide rod 35 slides in the guide groove 36 to guide and limit the arc clamping plate 32, making the arc clamping plate 32 more stable when moving, thereby improving the clamping stability of the bar. The movable seat 1 moves on the riveting machine workbench and drives the support plate 6 to move, so that the workpiece on the placing plate 2 moves to just below the hydraulic head of the riveting machine, and the slider 7 at the bottom of the support plate 6 slides in the slide groove 8 on the top of the riveting machine workbench to guide and support the movable seat 1, thereby improving the stability of the movable seat 1.

[0035] The working principles of the riveting machine and the clamp provided by the utility model are as follows:

[0036] When in use, the steel plate workpiece is placed between the fixed plate 4 and the clamping plate 5 on the top of the placing plate 2, and the clamping plate 5 moves on the placing plate 2 to clamp and fix the workpiece. The bar can be placed in the placing groove 34 in the moving seat 1 through the semicircular groove 33 in the middle of the fixing plate 4, and the arc clamping plate 32 is driven to move in the placing groove 34 by rotating the screw rod 31 to clamp and fix the bar. When the arc clamping plate 32 moves, the guide rod 35 slides in the guide groove 36 to guide and limit the arc clamping plate 32, making the arc clamping plate 32 more stable when moving, thereby improving the clamping stability of the bar. The moving seat 1 moves on the riveting machine workbench and drives the supporting plate 6 to move, so that the workpiece on the placing plate 2 moves to just below the hydraulic head of the riveting machine. The slider 7 at the bottom of the supporting plate 6 slides in the slide groove 8 on the top of the riveting machine workbench to guide and support the moving seat 1, thereby improving the stability of the moving seat 1.
