Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to clamping fixing systems. Background Technology

[0002] In industrial fields such as machining, fixture fixing systems are key devices to ensure stable workpiece processing. By reliably positioning and clamping the workpiece, they prevent displacement or shaking during processing, thereby ensuring machining accuracy and product quality.

[0003] After wet surface treatment of the workpiece, it needs to be moved to the next process by an overhead crane. The usual fixture only holds the top part of the workpiece for movement. However, if only the top part of the workpiece is held, the workpiece will sway back and forth due to inertia during the movement of the overhead crane to the target position. This will cause the workpiece to collide with the rest of the fixture and damage the surface of the workpiece. Furthermore, when the workpiece is lowered while swaying, it may get stuck in the narrow tank inlet, which may lead to an accident. To solve the above problems, this application proposes a fixture fixing system. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a clamping and fixing system. This system fixes the top and bottom of the workpiece, and the chamfered design of the limiting block ensures that the workpiece can be accurately placed in position. Furthermore, the system is made very robust, so that it can simultaneously fix the workpiece and prevent it from shaking during subsequent operation.

Two V-shaped connecting rods are rotatably connected to the lifting rod, and both V-shaped connecting rods are rotatably connected to the column. The ends of both V-shaped connecting rods are rotatably connected to the water receiving tray, and two rotating rods are rotatably connected to the water receiving tray. Both rotating rods are rotatably connected to the outer wall of the column, and two pairs of limiting blocks are fixedly connected to the top of the water receiving tray.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-4 The clamping system includes a column 1, with a workpiece 2 on the front of the column 1. Two clamping cylinders 3 are fixedly connected to the column 1. The clamping cylinders 3 act as driving components, outputting power to clamp the workpiece 2. A first limiting mechanism is provided between the workpiece 2 and each clamping cylinder 3. The first limiting mechanism includes two clamping blocks 4 fixedly connected to the output end of the clamping cylinder 3. The two clamping blocks 4 move relative to each other under the drive of the clamping cylinders 3 to clamp the workpiece 2. A first groove 6 is provided on the top of the workpiece 2. A fixing post 5 is fixedly connected to the inner wall of the first groove 6. Both clamping blocks 4 are inserted into the first groove 6 and clamped with the fixing post 5. The opposite ends of the two clamping blocks 4 are provided with arc surfaces. Both arc surfaces are set to abut against the outer wall of the fixing post 5. The arc surface design increases the contact area with the fixing post 5 and improves the stability of clamping.

[0023] Two connecting blocks 7 are fixedly connected to the column 1. A second limiting mechanism is provided between the workpiece 2 and each connecting block 7. The second limiting mechanism plays an auxiliary guiding and positioning role. The second limiting mechanism works in conjunction with the first limiting mechanism to further improve the accuracy of the installation of the workpiece 2. The second limiting mechanism includes a pin 8 fixedly connected to the bottom of the connecting block 7. A second groove 10 is opened on the top of the workpiece 2. A rubber sleeve 9 is fixedly connected to the outer wall of the pin 8. Both the pin 8 and the rubber sleeve 9 are inserted into the second groove 10. The outer wall of the rubber sleeve 9 abuts against the inner wall of the second groove 10. The rubber sleeve 9 increases the friction between the pin 8 and the second groove 10 to prevent the pin 8 from shaking in the second groove 10.

[0024] The bottom of workpiece 2 is provided with two base blocks 11 fixedly connected to it. A water receiving tray 12 is located below workpiece 2 to collect liquid dripping from the surface of workpiece 2 during processing. A hydraulic rod 14 is rotatably connected to the back end of column 1. A lifting rod 15 is rotatably connected to the output end of hydraulic rod 14. Two V-shaped connecting rods 16 are rotatably connected to the lifting rod 15. Both V-shaped connecting rods 16 are rotatably connected to column 1, and their ends are rotatably connected to the water receiving tray 12. The V-shaped connecting rods 16 convert the linear motion of the lifting rod 15 into the motion of the water receiving tray 12. During the lifting and lowering motion, the water receiving tray 12 is rotatably connected to two rotating rods 17. Both rotating rods 17 are rotatably connected to the outer wall of the column 1. The top of the water receiving tray 12 is fixedly connected to two pairs of limiting blocks 13. The limiting blocks 13 are used to limit and fix the bottom of the workpiece 2. The limiting blocks 13 work together with the clamping mechanism at the top to ensure the stability of the workpiece 2. The top of the limiting blocks 13 is chamfered so that the workpiece 2 can be accurately placed in place. It is also made very sturdy so that it can fix the workpiece 2 and prevent the workpiece 2 from shaking during the subsequent travel of this device.

[0025] In this application, after the workpiece 2 is grasped, there is a short wait until the water receiving tray 12 is started. After the water receiving tray 12 moves below the workpiece 2, the bottom block 11 set at the bottom of the workpiece 2 will fall onto a pair of limit blocks 13 inside the water receiving tray 12 and then start to move through the external crane.

[0026] In this invention, when it is necessary to clamp and fix the workpiece 2, the operator places the workpiece 2 below the clamping cylinder 3 and the connecting block 7, lifts the workpiece 2, and inserts the insert post 8 and rubber sleeve 9 into the second groove 10 to guide the workpiece 2. During this process, the two clamping blocks 4 are simultaneously inserted into the first groove 6. The clamping cylinder 3 moves the two clamping blocks 4 relative to each other to clamp the fixing post 5, thus fixing the top of the workpiece 2. Finally, the hydraulic rod 14 is activated, and its output end extends to drive the lifting rod 15 downward. The lifting rod 15 moves downward. The V-shaped connecting rod 16 is driven to rotate around its own center, thereby driving the water receiving tray 12 and the two pairs of limiting blocks 13 to move upward until the two pairs of limiting blocks 13 clamp the bottom of the bottom block 11, thus fixing the bottom of the workpiece 2. By limiting the top and bottom of the workpiece 2, the stability of the workpiece 2 can be ensured during subsequent movement. The chamfer of the limiting block 13 is designed so that the workpiece 2 can be accurately placed in place, and it is made very sturdy so that it can simultaneously fix the workpiece 2 and prevent the workpiece 2 from shaking during subsequent travel.
