Technical Field

[0001] This utility model relates to the technical field of valve processing, and in particular to a valve processing tooling. Background Technology

[0002] Valves are crucial control components in industrial piping systems, primarily controlling fluid flow rate, pressure, and direction. Therefore, their processing and manufacturing require highly sophisticated techniques. The quality and performance of valves directly impact the safe and stable operation of the entire system. Valve machining fixtures are specialized tools and equipment used to manufacture and process valve components. Their main function is to ensure that all valve components maintain precise position and orientation during processing, thereby improving machining accuracy and production efficiency, and ensuring the quality of the final valve product. Therefore, valve machining fixtures are particularly needed.

[0003] However, most existing valve machining fixtures cannot rotate the valve after clamping. The fixture position needs to be readjusted after each machining operation, which not only consumes a lot of time but also increases the number of operation steps, resulting in low overall machining efficiency. Each time the workpiece is re-clamped, its position may shift slightly, leading to the accumulation of machining errors. Utility Model Content

[0004] The purpose of this utility model is to provide a valve processing fixture to solve the problem mentioned in the background art. Most of the existing valve processing fixtures cannot rotate the valve after clamping. After each processing, the position of the fixture needs to be readjusted, which not only consumes a lot of time, but also increases the number of operation steps, resulting in low overall processing efficiency. Each time the workpiece is re-clamped, the position of the workpiece may be slightly offset, resulting in the accumulation of processing errors.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a valve processing fixture, including a base, a limiting groove provided inside the base, a rotating block installed inside the limiting groove, a motor installed at the lower end of the rotating block, an mounting plate installed at the upper end of the rotating block, a mounting bracket installed at the upper end of the mounting plate, a first connecting block installed on the inner side of the mounting bracket, a first connecting bolt connected to the inner side of the first connecting block, a support installed at the upper end of the first connecting block, a cylinder installed at the upper end of the mounting plate, a movable frame installed at the upper end of the cylinder, a second connecting block installed at the lower end of the movable frame, a second connecting bolt installed at the upper end of the second connecting block, and a clamp installed at the lower end of the second connecting block.

[0006] Preferably, a fixing plate is installed on the upper end of the base, a bracket is installed on one side of the fixing plate, a hydraulic cylinder is installed on the upper end of the bracket, a hydraulic rod is installed on the inner side of the hydraulic cylinder, a threaded groove is opened on the inner side of the hydraulic rod, a threaded rod is installed on the inner side of the threaded groove, and a pusher is installed on one end of the threaded rod.

[0007] Preferably, the rotating block forms a rotating structure with the motor and the limiting groove, and the mounting plate forms a rotating structure with the rotating block and the base.

[0008] Preferably, rubber pads are provided on the inner sides of both the support and the clamp.

[0009] Preferably, the bracket is connected to the mounting frame via a first connecting block and a first connecting bolt, and the clamp is connected to the movable frame via a second connecting block and a second connecting bolt.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This valve processing fixture, through the setting of a limiting groove, a rotating block, a motor and a mounting plate, allows the motor to drive the rotating block to rotate inside the limiting groove, and the rotating block to drive the valve to rotate.

[0017] 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.

[0018] Please see Figure 1-5 This utility model provides a technical solution: a valve processing fixture, including a base 1, a limiting groove 2 inside the base 1, a rotating block 3 installed inside the limiting groove 2, a motor 4 installed at the lower end of the rotating block 3, a mounting plate 5 installed at the upper end of the rotating block 3, a mounting bracket 6 installed at the upper end of the mounting plate 5, a first connecting block 7 installed on the inner side of the mounting bracket 6, a first connecting bolt 8 connected to the inner side of the first connecting block 7, a support 9 installed at the upper end of the first connecting block 7, and a cylinder installed at the upper end of the mounting plate 5. 10. A movable frame 11 is mounted on the upper end of cylinder 10, and a second connecting block 12 is mounted on the lower end of movable frame 11. A second connecting bolt 13 is mounted on the upper end of second connecting block 12, and a clamp 14 is mounted on the lower end of second connecting block 12. Through the arrangement of limiting groove 2, rotating block 3, motor 4, mounting plate 5, mounting frame 6, support 9, cylinder 10, movable frame 11, and clamp 14, the tooling can realize various operations such as valve rotation, clamping, positioning, and fixing, which can meet the needs of different processing processes. The cooperation between cylinder 10 and clamp 14 provides better clamping force, adapting to the processing of valves of different specifications and shapes.

[0019] Furthermore, a fixing plate 15 is installed on the upper end of the base 1, a bracket 16 is installed on one side of the fixing plate 15, a hydraulic cylinder 17 is installed on the upper end of the bracket 16, a hydraulic rod 18 is installed on the inner side of the hydraulic cylinder 17, a threaded groove 19 is opened on the inner side of the hydraulic rod 18, a threaded rod 20 is installed on the inner side of the threaded groove 19, and a push head 21 is installed on one end of the threaded rod 20. Through the arrangement of the hydraulic cylinder 17, hydraulic rod 18, threaded groove 19, threaded rod 20 and push head 21, the hydraulic cylinder 17 and hydraulic rod 18 form a powerful thrust source, which can provide enough force to drive the push head 21, which can push its parts into the valve to complete the processing. The push head 21 is connected to the hydraulic rod 18 through the threaded groove 19 and threaded rod 20, making it more convenient and faster to change the model of the push head 21.

[0020] Furthermore, the rotating block 3 forms a rotating structure with the limiting groove 2 via the motor 4, and the mounting plate 5 forms a rotating structure with the base 1 via the rotating block 3. Through the arrangement of the limiting groove 2, the rotating block 3, the motor 4, and the mounting plate 5, the motor 4 drives the rotating block 3 to rotate inside the limiting groove 2. The rotating block 3 drives the valve to rotate. By driving the rotating block 3 with the motor 4, the valve can complete multi-angle rotation processing in one clamping state, avoiding the need for multiple adjustments and re-clamping of the workpiece position in traditional tooling, thereby significantly improving the continuity and efficiency of processing.

[0021] Furthermore, rubber pads are provided on the inner sides of both the support 9 and the clamp 14. The rubber pads can provide better friction and increase the contact force between the support 9 and the clamp 14 and the workpiece, making the workpiece more stable during operation and preventing it from sliding or loosening.

[0022] Furthermore, the bracket 9 is connected to the mounting frame 6 via the first connecting block 7 and the first connecting bolt 8, and the clamp 14 is connected to the movable frame 11 via the second connecting block 12 and the second connecting bolt 13. By connecting the various components through the first connecting block 7, the first connecting bolt 8, the second connecting block 12, and the second connecting bolt 13, the disassembly work can be carried out in a standardized manner. Usually, only a few bolts need to be loosened to complete the disassembly, without the need for complicated tools or operations.

[0023] Working principle: In use, first place the air valve on the upper end of the support 9, then start the air cylinder 10. The air cylinder 10 drives the movable plate to retract. The movable plate drives the clamp 14 to fit against the support 9 through the second connecting block 12. The internal rubber pad clamps the valve. Then, put the part on the push head 21 once. Start the hydraulic cylinder 17. The hydraulic cylinder 17 pushes the hydraulic rod 18. The hydraulic rod 18 pushes the push head 21 into the valve to assemble the part. After completing one installation, start the motor 4. The motor 4 drives the rotating block 3 to rotate inside the limit groove 2. The rotating block 3 drives the valve to rotate. After adjusting the position, install again. When processing different models of valves, first remove the first bolt and the second bolt. After disassembly, remove the support 9 and the clamp 14 and replace them with the appropriate model. Then rotate the push head 21 so that the internal threaded rod 20 is pushed out of the hydraulic rod 18 through the threaded groove 19 to replace the push head. This completes the use of this valve processing tooling.
