Description

Technical Field

[0001] This utility model belongs to the field of compressor auxiliary disassembly and assembly tools, specifically relating to a compressor valve disassembly and assembly auxiliary clamping device. Background Technology

[0002] The gas valve is one of the most important components of the compressor. It opens and closes at a high frequency of hundreds of times per minute (300~1000 times / min) and works for a long time. In addition, the quality of the raw gas affects it, making it the most vulnerable part of the compressor. Therefore, the gas valve needs to be maintained and serviced in order for the compressor to run continuously.

[0003] In traditional operations, when disassembling and assembling the valve fastening nut, a bench vise is needed to hold the valve to prevent rotation. Because the valve is a smooth cylinder, the clamping is a two-point contact, which is very easy to slip and causes high clamping stress, easily leading to valve damage. Currently, the special tools developed for valve maintenance all require the use of a bench vise. However, due to limitations in production sites, bench vises are not available. When disassembling and assembling valves, operators use wrenches to tap the ground to tighten the valve fastening nut. This not only easily causes personnel injury but also makes it impossible to control the torque, causing damage to the valve through bolt and loss of the fastening nut's self-locking function. During unit operation, this can lead to the through bolt breaking or the fastening nut loosening, causing even greater hazards.

[0004] The existing technology patent with application number "CN202220949761.1" and title "Compressor Exhaust Valve Installation Platform" can play a certain role in stabilization, but it was later found that the structure is relatively expensive and still lacks model compatibility, stability and reliability. Utility Model Content

[0005] In view of this, the present invention provides an auxiliary clamping device for disassembling and assembling compressor valves to solve the problems of high cost, poor adaptability, stability and reliability of existing auxiliary tools.

[0006] The technical solution is as follows:

[0007] A compressor valve disassembly and assembly auxiliary clamping device, the key features of which are: a base and a support base, the base having a sliding groove, two sliders having sliding engagement with the groove, each slider having a mounting plate, the inner end of the slider having a detachable pin, and the outer end having a detachable vertically arranged adjusting screw, the support base having a support screw that engages with the mounting plate, and the two ends of the mounting plate being respectively fixed relative to the adjusting screw and the support screw.

[0008] Using the above solution, the air hole at the bottom of the air valve is placed directly opposite the pin during use. The pin restricts the rotation of the air valve. At the same time, the distance between the two mounting plates can be adjusted by sliding the slider in the groove, and the height of the mounting plates can be adjusted by adjusting the screw and the support screw. This allows for quick adaptation to different clamping models. The mounting plates and the pin work together to limit the circumferential, axial and radial movement of the air valve, preventing slippage. The required clamping force is small and will not cause stress damage to the air valve. The overall processing cost is low, and it has good adaptability and reliability.

[0009] Preferably, the mounting plate has strip-shaped holes arranged along its length, and these holes are adapted to the adjusting screw. Using this design, the spacing between the mounting plates can be adjusted without moving the slider, resulting in better adaptability.

[0010] Preferably, the mounting plate is fixed to the supporting screw and the adjusting screw using a double-nut fixing structure. This solution is convenient, quick to implement, and extremely low in cost, making it easy to promote.

[0011] Preferably, the slider has a pin hole adapted to the pin. This design facilitates quick pin replacement based on the vent diameter.

[0012] Preferably, the base has mounting holes at at least two opposite corners. Using this design, the base can be fixed to the location of use via the mounting holes, preventing external forces from affecting it.

[0013] Preferably, the slide groove has an inverted "T" shaped cross-section. This slide groove design simplifies manufacturing and effectively prevents the slider from warping upwards, thus improving the slider's stability.

[0014] Preferably, the slide groove is open at both ends, and the base has at least two baffle fixing holes at each end, with the two baffle fixing holes at the same end located on opposite sides of the slide groove. Using this design, after the slider is installed, baffles can be installed through the baffle fixing holes to seal the open ends of the slide groove, preventing the slider from sliding out of the slide groove during transport.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] The compressor valve disassembly and assembly auxiliary clamping device provided by this utility model mainly uses pins and mounting plates to achieve multi-directional limiting of the valve with only a small clamping force, avoiding stress damage to the valve while ensuring its disassembly and assembly stability. It can also be flexibly adjusted as needed to meet the disassembly and assembly requirements of multiple valve models. The overall processing cost is low, and it has good adaptability and reliability. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] refer to Figures 1 to 3 The compressor valve disassembly and assembly auxiliary clamping device of this application mainly includes a base 1 and a support base 6, as shown in the figure. In this embodiment, the base 1 is a plate-shaped structure with a certain thickness, and the bottom of the base 1 is a smooth plane with a sliding groove 10. There are two sliders 2 that slide with it in the sliding groove 10. The sliding plane of the slider 2 is parallel to the bottom surface of the base 1. The slider 2 has a corresponding mounting plate 3. The inner end of the slider 2 (referring to the end that is close to the middle of the base 1 after placement) has a pin 4 that is detachably set, and the outer end has an adjusting screw 5 that is detachably set vertically. The support base 6 has a support screw 7 that cooperates with the mounting plate 3. The two ends of the mounting plate 3 can be fixed relative to the adjusting screw 5 and the support screw 7 respectively.

[0022] In specific implementation, the platform 3 has a strip hole 30 arranged along its length. The strip hole 30 is adapted to the adjusting screw 5, and the two are fitted with a clearance. The adjusting screw 5 can pass through the strip hole 30. The platform 3 and the supporting screw 7, as well as the adjusting screw 5, are all fixed with a double nut structure. That is, the two ends of the platform 3 are fixed to the supporting screw 7 and the adjusting screw 5 respectively by two nuts, one above and one below. The upper nut used to fix the inner end of the platform 3 is a rat ear nut 50, which improves the ease of operation.

[0023] The slider 2 has pin holes that are compatible with the pin 4. In practice, multiple pin holes can be set at intervals to be used in conjunction with the strip hole 30, which can accommodate the fixing of more types of air valves.

[0024] The inner end of the ramp 3 is roughly a right-angled trapezoidal structure, which allows for better observation of the contact between the ramp 3 and the air valve, ensuring reliable operation.

[0025] The base 1 has base fixing holes 11 at least two opposite corners. In practice, base fixing holes 11 can be set at all four corners. The base 1 can be well fixed through the base fixing holes 11 to prevent shaking during disassembly and assembly from affecting operation.

[0026] In practice, the cross-section of the chute 10 is inverted "T" shape.

[0027] In addition, the slide 10 is open at both ends, and the base 1 has at least two baffle fixing holes 12 at each end, with the two baffle fixing holes 12 at the same end located on both sides of the slide 10. The support base 6 is a columnar structure with a smooth plane at the bottom and screw holes that mate with the support screw 7, mainly used for installing the support screw 7.

[0028] refer to Figures 1 to 3 The compressor valve disassembly and assembly auxiliary clamping device shown is used as follows: First, fix the base 1, then adjust the distance between the two sliders 2, that is, adjust the spacing of the pins 4 on the two sliders 2 to ensure that it is consistent with the spacing of the two symmetrical air holes on the valve to be disassembled and assembled, and ensure that the diameter of the pins 4 is compatible with it. Then, lower the valve with the air holes facing the pins 4. Next, adjust the height and inner end position of the mounting plate 3 to adapt to the valve. The height should be just enough to press against the outer step surface of the valve, and the spacing should be just enough to abut against the side wall. Finally, tighten the nut to perform the valve disassembly and assembly operation.
