Abstract
Description
Technical Field
[0001] This utility model relates to the field of valve technology, and in particular to an auxiliary device for valve production and processing. Background Technology
[0002] Valves are mechanical devices used to control the flow of fluids (liquids, gases, etc.). They control the on / off state, flow rate, and pressure of the medium by opening, closing, or adjusting components (such as valve discs and gates). Valves are classified by function into gate valves, globe valves, ball valves, check valves, etc.; and by actuation method into manual, electric, and pneumatic valves, etc. They are widely used in industrial pipelines, water supply and drainage, petrochemical, and gas industries, and are key components ensuring the safe and efficient operation of fluid systems.
[0003] A search revealed that CN221455667U discloses a positioning auxiliary tool for valve processing fixtures, including a base plate. A drive box is fixedly connected to the top of the base plate, and a threaded rod with both positive and negative threads is movably connected inside the drive box. Movable rods are threaded to both sides of the threaded rod, and the movable rods are movably connected to the drive box. A motor is fixedly connected to the left side of the drive box, and the output end of the motor is fixedly connected to the threaded rod. This utility model involves the operator placing the valve body between two clamping cones. The operator then starts the motor to rotate, causing the threaded rod to rotate, thereby moving the two movable rods, connecting rods, and clamping cones closer together. As the two clamping cones gradually approach each other, they insert into the valve body's inlet and outlet pipes, then come into close contact with them, thus fixing the valve body. This device is easy to use.
[0004] However, through exploration, the inventors have discovered that this technical solution still has at least the following defects:
[0005] After the device fixes the valve body, the valve body is in a completely fixed position and cannot be rotated or adjusted according to processing requirements. In actual valve processing, it is often necessary to process the surface and internal structure of the valve body at different angles. However, the fixed clamping method requires operators to frequently disassemble and reposition the valve body, which not only wastes time and reduces processing efficiency, but may also cause wear on the valve body surface or positioning deviation due to repeated disassembly and assembly, affecting processing accuracy and quality. Utility Model Content
[0006] The present invention aims to provide an auxiliary device for valve production and processing to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A valve manufacturing and processing auxiliary device includes an operating table, with two sets of abutment devices slidably connected to the operating table. The operating table is connected to two fixed frames and a motor. The output end of the motor is connected to a bidirectional screw, and both fixed frames are rotatably connected to the bidirectional screw.
[0009] The abutting device includes a mounting platform. The two ends of the bidirectional screw are threadedly connected to two mounting platforms respectively. The mounting platforms are slidably connected to an operating table. Each mounting platform is connected to a first connecting rod. There are two first connecting rods, which are rotatably connected to a rotating shaft. The rotating shaft is connected to a worm gear and an abutting part. The mounting platform is connected to two mounting plates, which are rotatably connected to a worm. The worm is connected to a first bevel gear, which meshes with the worm gear. The two first connecting rods are rotatably connected to a rotating rod, which is connected to a second bevel gear. The first bevel gear meshes with the second bevel gear. The two rotating rods are movably sleeved together.
[0010] Preferably, the operating table is provided with a sliding groove, the side wall of the sliding groove is provided with a sliding groove, and the side wall of the mounting table is connected to a slider, the slider being slidably connected to the inner wall of the sliding groove.
[0011] Preferably, the rotating shaft and the contact part are detachably connected by a thread.
[0012] Preferably, the two rotating rods are respectively provided with a first connecting part and a second connecting part, the first connecting part and the second connecting part are movably connected, and the longitudinal section of the first connecting part and the second connecting part are both rectangular.
[0013] Preferably, the contact portion is frustum-shaped.
[0014] Preferably, the worm gear is connected to a handle.
[0015] The beneficial effects of this technical solution compared to existing technologies are as follows:
[0016] (1) This solution solves the problem in the prior art where the valve body cannot be adjusted after it is fixed by setting a meshing transmission structure of worm and worm wheel, and first bevel gear and second bevel gear in the contact device. After the contact part clamps the valve, it can drive the valve to rotate by rotating the worm. Operators do not need to frequently disassemble the valve and can directly process different surfaces or internal structures of the valve body through the rotation function, which significantly improves processing efficiency, avoids surface wear and positioning deviation caused by multiple disassembly and assembly, and improves processing accuracy. At the same time, the bidirectional screw and two sets of contact devices can synchronously adjust the distance between the contact parts to adapt to valves of different sizes. Combined with the stability of the transmission structure, it ensures that the valve is reliably clamped during rotation.
[0017] (2) The sliding groove of the operating table cooperates with the slider of the mounting table. The sliding groove guides the mounting table to make it slide more smoothly, avoids deviation, ensures accurate positioning of the contact device during movement, and improves the overall stability of the device.
[0018] (3) The rotating shaft and the contact part are connected by a threaded detachable connection, which makes it easy to replace the appropriate contact part according to the interface size of different valves, improves the versatility of the device and reduces the replacement cost.
[0019] (4) The first connecting part and the second connecting part of the rotating rod are slidably connected and the longitudinal section is rectangular, which allows the length of the rotating rod to be adjusted within a certain range to adapt to the contact devices with different spacing. At the same time, the rectangular structure ensures stable torque transmission during transmission and avoids slippage.
[0020] (5) The contact part is designed in the shape of a frustum, which can be tightly inserted into the feed pipe or discharge pipe of the valve. The conical structure increases the contact area and friction, improves the clamping firmness, and prevents the valve from sliding during processing. At the same time, the frustum shape can be adapted to more valves with different inner diameters.
[0021] (6) The worm gear connecting handle provides a manual rotation drive mode, which does not require an additional power source. Operators can flexibly control the valve rotation angle to meet the needs of fine processing and enhance the ease of operation of the device. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:
[0027] like Figures 1 to 3The valve manufacturing and processing auxiliary device shown includes an operating table 1, with abutment devices 2 slidably connected to both the left and right sides of the operating table 1, and fixed frames 4 connected to both the left and right sides of the operating table 1. A motor 5 is connected to the left side of the operating table 1, and a bidirectional screw 6 is connected to the output end of the motor 5. Both fixed frames 4 are rotatably connected to the bidirectional screw 6.
[0028] The abutment device 2 includes a mounting platform 7, a bidirectional screw 6 threadedly connected to two mounting platforms 7, a mounting platform 7 slidably connected to an operating platform 1, a first connecting rod 8 connected to both the left and right sides of the mounting platform 7, a rotating shaft 10 rotatably connected to both first connecting rods 8, a worm gear 12 connected to the rotating shaft 10 and an abutment part 11, the abutment part 11 being frustum-shaped, mounting plates 9 connected to the front and rear sides of the mounting platform 7, a worm 13 rotatably connected to both mounting plates 9, a first bevel gear 14 and a handle 21 respectively connected to both ends of the worm 13, the worm 13 and the worm gear 12 meshing, a rotating rod 16 rotatably connected to both first connecting rods 8, a second bevel gear 19 connected to the rotating rod 16, the first bevel gear 14 and the second bevel gear 19 meshing, and the rotating rods 16 of the two abutment devices 2 being movably sleeved together.
[0029] When the valve needs to be clamped, motor 5 is turned on. The output of motor 5 drives the bidirectional screw 6 to rotate. The bidirectional screw 6 drives the two mounting platforms 7, which are threaded to it, to move synchronously in opposite directions. When the two contact parts 11 are adjusted to a suitable distance, the valve is placed between the two contact parts 11. The two contact parts 11 abut against the inner wall of the valve to achieve fixation. Then, motor 5 is turned on again, and the distance between the two contact parts 11 is adjusted until the valve is clamped. At this time, the first connecting part 17 and the second connecting part 18 of the two rotating rods 16 are sleeved together.
[0030] When the valve needs to be turned, handle 21 is turned. Handle 21 drives worm 13 and first bevel gear 14 to rotate. Worm 13 drives worm wheel 12, which meshes with it, to rotate. Worm wheel 12 drives shaft 10 and the contact part 11 connected to shaft 10 to rotate. First bevel gear drives second bevel gear 19 and the rod 16 connected to it to rotate. Rod 16 drives the first bevel gear 14 of another set of contact devices 2 to rotate, which in turn drives worm 13 connected to it to rotate. Worm 13 drives worm wheel 12, which meshes with it, and shaft 10 connected to it to rotate. Shaft 10 drives the contact part to rotate. Thus, the contact parts 11 of the two contact devices 2 rotate synchronously in the same direction.
[0031] The operating table 1 is provided with a sliding groove 3, and the two side walls of the sliding groove 3 are provided with sliding grooves. The two side walls of the mounting table 7 are connected with sliders 20, and the sliders 20 are slidably connected to the inner wall of the sliding groove.
[0032] The rotating shaft 10 and the contact part 11 are detachably connected by threads.
[0033] The two rotating rods 16 are respectively provided with a first connecting part 17 and a second connecting part 18. The first connecting part 17 and the second connecting part 18 are movably connected. The longitudinal section of the first connecting part 17 and the second connecting part 18 is rectangular.
[0034] The specific implementation process is as follows:
[0035] When using the device, the worker first places the valve on the operating table 1, aligning the valve's inlet and outlet pipes with the two opposing contact devices 2. Then, the motor 5 is started, driving the bidirectional screw 6 to rotate. Through a threaded connection, the two mounting platforms 7 slide synchronously towards each other along the sliding groove 3. The sliders 20 on both sides of the mounting platform 7 move smoothly within the groove until the two contact parts 11 (frustum-shaped) initially approach the valve interface. At this point, the first connecting part 17 and the second connecting part 18 of the two rotating rods 16 slide together, and the rectangular cross-section ensures that the transmission structures of the two sets of contact devices are synchronized.
[0036] Once the contact part 11 is close to the valve interface, the worker continues to fine-tune the spacing using the motor 5, ensuring the frustum-shaped contact part is tightly inserted into the valve pipe. The conical surface increases friction to achieve clamping and fixation. When the valve needs to be rotated, the worker manually rotates the handle 21 on the worm gear 13. The handle drives the worm gear to rotate, and through the meshing of the worm gear and worm wheel 12, it drives the rotating shaft 10 and the contact part 11 to rotate. Simultaneously, the first bevel gear 14 meshes with the second bevel gear 19, transmitting power to the contact device 2 on the other side, causing the two contact parts to rotate synchronously in the same direction. This facilitates the worker's processing of the valve's surface or interior at different angles.
[0037] If encountering valves with different interface sizes, workers can directly disassemble the contact part 11 via threaded connection and replace it with a suitable contact part 11, without the need for a complete disassembly device, significantly improving processing efficiency. Throughout the process, the cooperation between the sliding groove and the slider ensures smooth movement of the mounting table, and the stability of the transmission structure ensures that the valve is firmly clamped during rotation, avoiding wear and positioning deviations caused by frequent disassembly and assembly, thus meeting the requirements for precision and efficiency in actual processing.
