Description

Technical Field

[0001] This utility model relates to the technical field of valve body processing clamping mechanism, specifically a multi-station clamping mechanism for valve body processing. Background Technology

[0002] The valve body is the main pressure-bearing component of a valve, forming the flow path and pressure boundary for the medium. It has interfaces for connecting pipes or equipment. Clamping refers to the process of accurately positioning and firmly clamping the valve body using special fixtures when machining it on CNC machine tools or other equipment. This ensures its stability during machining and meets various geometric tolerances and dimensional accuracy requirements.

[0003] Drilling is often required during the production and processing of valve bodies. However, valve bodies have many drilling positions, making adjustment troublesome. Moreover, their structural sizes vary, resulting in traditional clamping devices being applicable to only a limited range of types but lacking flexibility. Therefore, a clamping mechanism that is convenient for clamping and switching is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-station clamping mechanism for valve body processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-station clamping mechanism for valve body processing, including a base, a support fixedly connected to the upper side of the base, and a functional valve disposed on the upper side of the support. An adjustment and positioning mechanism and a clamping mechanism are disposed on the upper side of the support, and the adjustment and positioning mechanism is disposed outside the clamping mechanism.

[0006] The adjustment and positioning mechanism includes a housing, which is fixedly connected to one side of the support. A motor is fixedly connected inside the housing. Multiple sliders are slidably connected inside the support. A screw is fixedly connected to the output end of the motor. All sliders are threadedly connected to the screw. A clamp is fixedly connected to the upper surface of each slider. Multiple pneumatic cylinders are fixedly connected inside the clamp. A connector is provided at the bottom of each pneumatic cylinder. A piston disc is slidably connected inside each pneumatic cylinder. A piston rod is fixedly connected to the upper surface of each piston disc. A clamping rod is fixedly connected to the upper end of each piston rod. A clamping groove is opened on the adjacent side of each clamping rod.

[0007] Preferably, the slider is configured in an approximately U-shape.

[0008] Preferably, the pneumatic cylinders are all located at multiple corners of the clamp.

[0009] Preferably, all the clamping grooves are provided with a trapezoidal cross-section.

[0010] Preferably, the clamping mechanism includes multiple sliding cavities and bidirectional studs. The sliding cavities are all opened inside the clamping seat. Multiple sets of clamping blocks are slidably connected inside the sliding cavities. Adjacent clamping blocks are set as a group. A limiting groove is opened at the lower end of the side away from each other in each group of clamping blocks. An oblique opening is opened on the side close to each other in each group of clamping blocks. Multiple sliding seats are slidably connected inside the sliding cavities. A limiting block is fixedly connected to the upper surface of the side close to each of the multiple sliding seats. The limiting block is slidably connected to the adjacent limiting groove. The bidirectional studs are rotatably connected inside the clamping seat. The bidirectional studs are slidably connected to the adjacent sliding seats.

[0011] Preferably, the clamping block has an approximately rhomboid structure.

[0012] Preferably, the upper end of the slide is provided with an inclined surface parallel to the limiting groove.

[0013] Compared with the prior art, this utility model provides a multi-station clamping mechanism for valve body machining, which has the following advantages:

[0014] 1. The adjustment and positioning mechanism is used to quickly position and limit the valve body. This mechanism uses a slider and a screw to quickly adjust the specific position of the functional valve, which is convenient for the processing device to process it. In addition, the device uses a clamping rod to quickly limit the valve body, which is convenient for users to quickly disassemble and assemble, thereby improving the user's switching efficiency.

[0015] 2. The clamping mechanism is used to clamp the functional valve. This mechanism uses multiple inclined blocks to abut the bottom of the functional valve, and works in conjunction with the adjusting and positioning mechanism to assist in clamping the functional valve. This ensures that the multiple machining surfaces of the valve body are not interfered with by the fixture, avoids the trouble caused by frequently adjusting the valve body posture, and improves machining efficiency.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] Example 1:

[0026] Please see Figure 1-5 This utility model provides a technical solution: a multi-station clamping mechanism for valve body processing, including a base 1, a support 2 fixedly connected to the upper side of the base 1, and a functional valve 5 set on the upper side of the support 2. An adjustment and positioning mechanism 3 and a clamping mechanism 4 are set on the upper side of the support 2, and the adjustment and positioning mechanism 3 is set on the outside of the clamping mechanism 4.

[0027] This mechanism is used for positioning and clamping the functional valve 5. This mechanism improves the clamping adaptability of the device. The adjusting positioning mechanism 3 includes a housing 301, which is fixedly connected to one side of the support 2. A motor 302 is fixedly connected inside the housing 301. Multiple sliders 303 are slidably connected inside the support 2. A screw 304 is fixedly connected to the output end of the motor 302. All sliders 303 are threadedly connected to the screw 304. A clamping seat 305 is fixedly connected to the upper surface of each slider 303. A clamping seat 305 is fixedly connected inside the clamping seat 305. Multiple pneumatic cylinders 306 are provided, each with a connector 307 at its bottom. A piston disc 308 is slidably connected inside each pneumatic cylinder 306, and a piston rod 309 is fixedly connected to the upper surface of each piston disc 308. A clamping rod 310 is fixedly connected to the upper end of each piston rod 309, and clamping grooves 311 are formed on adjacent sides of each clamping rod 310. This adjustment and positioning mechanism 3 drives a screw 304 to rotate via a motor 302, using the threaded transmission principle to drive multiple sliders 303 to move synchronously along the support 2 (see...). Figure 2-3 This enables the switching of the working positions of the functional valves 5 on multiple clamping seats 305. The pneumatic cylinder 306 is connected to an external air source via a connector 307, using air pressure to drive the piston disc 308 to move the clamping rod 310 to complete the clamping action on the upper port of the valve body (see...). Figure 4 The trapezoidal cross-section design of the clamping groove 311 increases the contact area with the arc surface of the valve body, and achieves a stable and uniform clamping force distribution through Pascal's principle.

[0028] Furthermore, slider 303 is set in an approximately U-shape.

[0029] Furthermore, the pneumatic cylinders 306 are all located at multiple corners of the clamp 305.

[0030] Furthermore, all clamping grooves 311 are designed with a trapezoidal cross-section.

[0031] Example 2:

[0032] This mechanism is used for position adjustment and auxiliary clamping of function valve 5, improving the clamping flexibility of the device. (See also...) Figure 1-5Furthermore, in conjunction with Embodiment 1, the clamping mechanism 4 includes multiple sliding cavities 401 and bidirectional studs 407. Each sliding cavity 401 is located inside the clamping seat 305. Multiple sets of clamping blocks 402 are slidably connected inside each sliding cavity 401, with adjacent blocks forming a group. Each group of clamping blocks 402 has a limiting groove 403 at its lower end on the side furthest from each other, and a bevel 404 on the side adjacent to each other. Multiple sliding seats 405 are slidably connected inside each sliding cavity 401. Limiting blocks 406 are fixedly connected to the upper surface of the adjacent side of each sliding seat 405, and the limiting blocks 406 are slidably connected to adjacent limiting grooves 403. The bidirectional studs 407 are rotatably connected inside the clamping seat 305, and are slidably connected to adjacent sliding seats 405. The clamping mechanism 4 drives the sliding seats 405 to move towards each other by rotating the bidirectional studs 407 (see [link]). Figure 5 The horizontal displacement is converted into the vertical movement of the clamping block 402 by the inclined surface cooperation between the limiting block 406 and the limiting groove 403. The wedge-shaped self-locking effect is formed by the inclined opening 404 and the bottom contour of the valve body (see...). Figure 3 The mechanical force-increasing mechanism and the upper pneumatic clamping form a two-way constraint, which not only avoids displacement caused by processing vibration, but also ensures the degree of freedom of exposure of multiple machined surfaces of the valve body, meeting the process requirements of multi-process centralized processing.

[0033] Furthermore, the clamping block 402 is configured with an approximately rhomboid structure.

[0034] Furthermore, the upper end of the slide 405 is provided with an inclined surface parallel to the limiting groove 403.

[0035] In actual operation, when this device is in use, the piston rods 309 are all in the extended state. The user places the function valve 5 on the upper side of the clamp 305. The user can drive the slides 405 to approach each other by rotating the bidirectional stud 407. When the slides 405 move, they lift the adjacent clamping blocks 402 to adjust the height of the function valve 5 or to further clamp the function valve 5 with the clamping rod 310. Then the user straightens the function valve 5 and drives the clamping rod 310 to hold the function valve 5 by retracting multiple pneumatic cylinders 306. This locks multiple points of the function valve 5 with the clamping blocks 402 and the clamping rod 310, thereby limiting the function valve 5. Then the user can start the motor 302. The motor 302 drives the screw 304 to drive multiple sliders 303 to adjust their positions so that after one function valve 5 is processed, another clamped function valve 5 can be sent to the processing area, so that the processing process can be continuous.
