Description

Technical Field

[0001] This application relates to the field of compressors, and in particular to a compressor suction cup assembly and its manufacturing process. Background Technology

[0002] The suction cup is one of the key components in a reciprocating compressor. The compressor suction cup assembly is located at the lowest end of the engine and consists of a pulley, a coil, and a suction cup. The pulley rotates with the engine wheel. When the compressor clutch is engaged, the compressor coil is energized to generate magnetic force, and the suction cup is attracted to the pulley. The suction cup is connected to the compressor main shaft in the middle. The suction cup transmits the rotation of the engine to the compressor, driving the movement of the internal components of the compressor. At the same time, the moving parts inside the compressor will generate dynamic imbalance during high-speed operation. The suction cup plays a role in adjusting the dynamic balance during the high-speed operation of the compressor.

[0003] The suction cup and the pulley are in surface contact. Traditional suction cups will reduce their static friction torque due to wear during long-term operation, resulting in insufficient suction force. This causes the suction cup and the pulley to slip and burn during rotation, affecting the normal operation of the compressor. Summary of the Invention

[0004] In order to extend the service life of the compressor, this application provides a compressor suction cup assembly and its processing technology.

[0005] The compressor suction cup assembly and its processing technology provided in this application adopt the following technical solution:

[0006] In a first aspect, this application provides a compressor suction cup assembly, which adopts the following technical solution:

[0007] A compressor suction cup assembly includes a wheel body, a disc body, and a rubber ring. One side of the wheel body is coaxially provided with a mounting ring groove for placing a coil. The other side of the wheel body is coaxially provided with a placement groove for embedding the disc body. The bottom of the placement groove is coaxially provided with a placement ring groove, and the rubber ring is embedded in the placement ring groove. The side of the disc body facing the wheel body is coaxially provided with a limiting ring groove, and the end of the rubber ring away from the bottom of the placement ring groove abuts against the bottom of the limiting ring groove.

[0008] By adopting the above technical solution, the coil generates magnetic force when energized, attracting the disc to the wheel and causing the rubber ring to abut against the bottom of the limiting groove, so that the disc rotates with the wheel. The rubber ring increases the friction between the disc and the wheel, and it is easy to replace the rubber ring after it wears out, thus extending the service life of the compressor.

[0009] Preferably, a compressor suction cup assembly further includes a rubber pad, which is fixedly connected to the groove wall of the limiting ring groove facing the axis of the disc body, and one end of the rubber pad facing the axis of the disc body is used for the rubber ring to abut against it.

[0010] By adopting the above technical solution, the rubber pad and the rubber ring abut against each other, increasing the friction between the disc and the wheel, making it easier for the disc to rotate with the wheel, reducing the probability of relative sliding between the disc and the wheel, and improving the working quality of the compressor.

[0011] Preferably, a compressor suction cup assembly further includes a clamping block, wherein the groove wall of the limiting ring groove opposite to the axis of the disc body is provided with a sliding groove, the clamping block is slidably connected to the groove wall of the sliding groove, the clamping block slides along the radial direction of the disc body, and one end of the clamping block opposite to the axis of the disc body is used to clamp a rubber ring.

[0012] By adopting the above technical solution, the sliding abutment block abuts the rubber strip, which further increases the friction between the rubber strip and the groove wall of the limiting ring groove, so that the disc can rotate stably with the wheel. While the disc rotates, centrifugal force is generated, which causes the abutment block to move in a direction away from the axis of the disc, making it easier for the abutment block to exert greater pressure on the groove wall of the limiting groove.

[0013] Preferably, a compressor suction cup assembly further includes a first spring, one end of which is fixedly connected to the bottom of the sliding groove, and the other end of which is fixedly connected to one end of the abutment block.

[0014] By adopting the above technical solution, the first spring causes the clamping block to press against the rubber ring, increasing the friction between the clamping block and the rubber ring, so that the disc rotates stably with the wheel, thereby improving the working quality of the compressor.

[0015] Preferably, the end of the abutment block facing the rubber ring has a guide surface, and the distance from the guide surface to the bottom of the limiting ring groove decreases as it moves away from the first spring.

[0016] By adopting the above technical solution, the guide surface facilitates the rubber ring to be embedded in the limiting ring groove, so that the clamping block clamps the rubber ring, thereby improving the working efficiency of the compressor.

[0017] Preferably, there are multiple sliding grooves, which are evenly spaced around the axis of the disc body, and multiple abutting blocks are provided, with each abutting block corresponding to one of the sliding grooves.

[0018] By adopting the above technical solution, multiple clamping blocks make the connection between the disc and the wheel more stable, thus improving the working quality of the compressor.

[0019] Preferably, a compressor suction cup assembly further includes a metal ring, and a fixing ring groove is coaxially provided at the bottom of the placement groove. The fixing ring groove is located on the inner circumference of the placement groove. The metal ring is slidably connected to the groove wall of the fixing ring groove. The sliding direction of the metal ring is parallel to the axis of the disc body. The end of the metal ring facing the pressing block is provided with a rounded corner, which is used to abut against the guide surface.

[0020] By adopting the above technical solution, after the coil is energized, the metal ring moves away from the pressing block and is embedded in the fixed ring groove. After the coil is de-energized, the metal ring moves towards the pressing block and pushes the disc away from the wheel, so that the disc and the wheel separate in time after the coil is de-energized, thus improving the working quality of the compressor.

[0021] Preferably, a compressor suction cup assembly further includes a second spring, one end of which is fixedly connected to the bottom of the fixing ring groove, and the other end of which is fixedly connected to a metal ring.

[0022] By adopting the above technical solution, after the coil is energized, the metal ring moves away from the clamping block, the second spring contracts, and after the coil is de-energized, the second spring resets and pushes the metal ring to move closer to the clamping ring, which facilitates the separation of the disc body and the wheel body.

[0023] Preferably, a positioning block is connected to the bottom of the placement ring groove, and a positioning groove is provided at one end of the rubber ring facing the bottom of the placement ring groove, the positioning groove being used for the positioning block to be embedded.

[0024] By adopting the above technical solution, the rubber ring is embedded in the placement groove and the positioning block is embedded in the positioning groove, so that the rubber ring is not easy to rotate relative to the wheel body, and the rubber ring rotates stably with the wheel body, which facilitates the rotation of the disc body through the rubber ring.

[0025] Secondly, this application provides a processing technology for a compressor suction cup assembly, employing the following technical solution:

[0026] A process for manufacturing a compressor suction cup assembly includes the following steps:

[0027] The wheel body is injection molded, and the disc body is cast.

[0028] Place the coil inside the mounting ring groove;

[0029] Embed the rubber ring into the placement groove;

[0030] The first spring and the abutment block are connected in the sliding groove;

[0031] The second spring and the metal ring are connected in the fixed ring groove;

[0032] Pass the compressor main shaft through the wheel body, and place the disc body on the compressor main shaft so that the rubber ring is aligned with the limit ring groove.

[0033] By adopting the above technical solution, the coil generates magnetic force when energized, attracting the disc body so that it is tightly attached to the wheel body. The rubber ring is embedded in the limiting ring groove and abuts against the rubber pad. The second spring contracts, causing the metal ring to move away from the disc body. The first spring pushes the clamping block to press against the rubber ring, increasing the friction between the rubber ring and the rubber pad. The wheel body rotates, causing the disc body to rotate. When the coil is de-energized, the electromagnetic force disappears. The second spring returns to its original shape, causing the metal ring to abut against the guide surface. The clamping block separates from the rubber ring. The first spring contracts, and the metal ring pushes the disc body, causing the rubber ring to disengage from the limiting ring groove. The first spring returns to its original shape, causing the clamping block to push the metal ring away from the disc body, thus completely separating the disc body from the wheel body.

[0034] In summary, this application includes at least one of the following beneficial technical effects:

[0035] 1. When the coil is energized, it generates a magnetic force that attracts the disc to the wheel and causes the rubber ring to abut against the bottom of the limiting groove, so that the disc rotates with the wheel. The rubber ring increases the friction between the disc and the wheel, and it is easy to replace the rubber ring after it wears out, thus extending the service life of the compressor.

[0036] 2. The sliding of the clamping block against the rubber strip further increases the friction between the rubber strip and the groove wall of the limiting ring, allowing the disc to rotate stably with the wheel. The rotation of the disc generates centrifugal force, causing the clamping block to move away from the axis of the disc, making it easier for the clamping block to exert greater pressure on the groove wall of the limiting ring.

[0037] 3. When the coil is energized, it generates a magnetic force that attracts the disc, causing it to adhere tightly to the wheel. The rubber ring is embedded in the limiting ring groove and abuts against the rubber pad. The second spring contracts, causing the metal ring to move away from the disc. The first spring pushes the clamping block to press against the rubber ring, increasing the friction between the rubber ring and the rubber pad. The wheel rotates, causing the disc to rotate. When the coil is de-energized, the electromagnetic force disappears. The second spring returns to its original shape, causing the metal ring to abut against the guide surface. The clamping block separates from the rubber ring. The first spring contracts, and the metal ring pushes the disc, causing the rubber ring to disengage from the limiting ring groove. The first spring returns to its original shape, causing the clamping block to push the metal ring away from the disc, completely separating the disc from the wheel. Attached Figure Description

[0040] The following is in conjunction with the appendix Figure 1 This application will be described in further detail.

[0041] This application discloses a compressor suction cup assembly. (Refer to...) Figure 1 A compressor suction cup assembly includes a wheel body 1, a disc body 2, a rubber ring 3, a rubber pad 4, a clamping block 5, a first spring 6, a rotating ring 7, a second spring 8, and a metal ring 9.

[0042] Reference Figure 1 The wheel body 1 is coaxially provided with a through-hole 11, which passes through the wheel body 1 and is used for the compressor main shaft to pass through. The wheel body 1 is coaxially rotatably connected to the outer wall of the compressor main shaft. The disc body 2 is coaxially provided with a through-hole 21, which passes through the disc body 2. The inner wall of the through-hole 21 is provided with a keyway 211, the length direction of the keyway 211 is parallel to the axis of the through-hole 21, and the keyway 211 extends to both ends to pass through the disc body 2. The through-hole 21 is used for the compressor main shaft to pass through, and the keyway 211 is used for the key on the outer wall of the compressor main shaft to pass through. The disc body 2 slides along the axial direction of the compressor main shaft and is a metal disc.

[0043] The wheel body 1 is coaxially provided with a mounting ring groove 12 at the end opposite to the disc body 2. The mounting ring groove 12 is used to place the coil. When the coil is energized, it generates a magnetic force to attract the disc body 2. The outer wall of the wheel body 1 is coaxially provided with a connecting groove 13. The connecting groove 13 is used for the belt to be fitted. The engine drives the wheel body 1 to rotate through the belt.

[0044] Reference Figure 1 The wheel body 1 has a placement groove 14 coaxially arranged at one end facing the disc body 2. The placement groove 14 is connected to the through opening 11. The disc body 2 is slidably embedded in the placement groove 14. The outer diameter of the disc body 2 decreases as it approaches the bottom of the placement groove 14. The bottom of the placement groove 14 has a placement ring groove 141 coaxially arranged. The bottom of the placement ring groove 141 is fixedly connected to a positioning block 142. There are two positioning blocks 142. The two positioning blocks 142 are evenly spaced around the axis of the placement ring groove 141. The rubber ring 3 is embedded in the placement ring groove 141. The end of the rubber ring 3 facing the bottom of the placement ring groove 141 has a positioning groove 31. There are two positioning grooves 31. The positioning grooves 31 are arranged one-to-one with the positioning blocks 142. The positioning grooves 31 are used for the positioning blocks 142 to be embedded.

[0045] The disc body 2 is coaxially provided with a limiting ring groove 22 at one end facing the wheel body 1. The limiting ring groove 22 is used for the rubber ring 3 to be inserted at one end away from the positioning block 142. The rubber ring 3 is used to abut against the bottom of the limiting ring groove 22. The width of the rubber ring 3 is equal to the sum of the groove depth of the limiting ring groove 22 and the groove depth of the placement ring groove 141. The rubber pad 4 is fixedly connected to the groove wall of the limiting ring groove 22 facing the axis of the disc body 2. The end of the rubber pad 4 facing the axis of the disc body 2 is used for the end of the rubber ring 3 away from the axis of the disc body 2 to abut against it.

[0046] Reference Figure 1 The limiting ring groove 22 has a sliding groove 221 on its groove wall opposite to the axis of the disc body 2. There are twelve sliding grooves 221, which are evenly spaced around the axis of the disc body 2. There are twelve abutting blocks 5, which are arranged one-to-one with the sliding grooves 221. There are twelve first springs 6, which are arranged one-to-one with the abutting blocks 5. Both the first springs 6 and the abutting blocks 5 are located in the sliding grooves 221. One end of the first spring 6 is fixedly connected to the bottom of the sliding groove 221, and the other end of the first spring 6 is fixedly connected to the abutting block 5. The abutting block 5 slides along the radial direction of the disc body 2. The end of the abutting block 5 opposite to the axis of the disc body 2 is used to abut the end of the rubber ring 3 facing the axis of the disc body 2.

[0047] A rotating ring 7 is located on the side of the abutment block 5 near the bottom of the placement groove 14. The inner wall of the rotating ring 7 is threaded to the bottom of the sliding groove 221. The end of the rotating ring 7 facing away from the bottom of the placement groove 14 is used to limit the position of the abutment block 5, facilitating the installation of the first spring 6 and the abutment block 5, and preventing the abutment block 5 from disengaging from the sliding groove 221. The end of the abutment block 5 facing the rubber ring 3 is provided with a guide surface 51. The distance from the guide surface 51 to the bottom of the limiting ring groove 22 decreases as it moves away from the first spring 6.

[0048] Reference Figure 1 The bottom of the placement groove 14 is coaxially provided with a fixing ring groove 143, which is located on the inner circumference of the placement groove 141. The second spring 8 and the metal ring 9 are both located in the fixing ring groove 143. One end of the second spring 8 is fixedly connected to the bottom of the fixing ring groove 143, and the other end of the second spring 8 is fixedly connected to the metal ring 9. The metal ring 9 is slidably connected to the groove wall of the fixing ring groove 143. The sliding direction of the metal ring 9 is parallel to the axial direction of the disc body 2. There are four second springs 8, which are evenly spaced around the axis of the disc body 2. The end of the metal ring 9 facing the pressing block 5 is provided with a rounded corner 91, which is used to abut against the guide surface 51.

[0049] The implementation principle of a compressor suction cup assembly in this application embodiment is as follows: When the coil is energized, the second spring 8 contracts, the metal ring 9 moves away from the disc body 2, the rubber ring 3 is embedded in the limiting ring groove 22, the first spring 6 causes the pressing block 5 to press against the rubber ring 3, and increases the friction between the rubber ring 3 and the rubber pad 4. When the wheel body 1 rotates, it drives the disc body 2 to rotate. The rotation of the disc body 2 generates centrifugal force, and the pressing block 5 further presses against the rubber ring 3. When the coil is de-energized, the second spring 8 returns to its original position, the metal ring 9 moves towards the disc body 2, the rounded corner 91 abuts against the guide surface 51, causing the pressing block 5 to move towards the axis of the disc body 2, and causing the first spring 6 to contract. The metal ring 9 pushes the disc body 2 away from the wheel body 1, causing the rubber ring 3 to disengage from the limiting ring groove 22. The first spring 6 pushes the second spring 8 to disengage from the limiting ring groove 22. The first spring 6 and the second spring 8 separate, and the disc body 2 and the wheel 1 separate.

[0050] This application also discloses a processing technology for a compressor suction cup assembly. (Refer to...) Figure 1 A compressor suction cup assembly processing technology includes the following steps:

[0051] Wheel body 1 is injection molded; disc body 2 is cast.

[0052] Place the coil inside the mounting ring groove 12;

[0053] Embed the rubber ring 3 into the placement ring groove 141;

[0054] The first spring 6 and the abutment block 5 are connected in the sliding groove 221;

[0055] Install rotating ring 7;

[0056] The second spring 8 and the metal ring 9 are connected in the fixed ring groove 143;

[0057] The compressor main shaft passes through the wheel body 1, and the disc body 2 is fitted onto the compressor main shaft so that the rubber ring 3 is aligned with the limiting ring groove 22.

[0058] The implementation principle of the compressor suction cup assembly processing technology in this application embodiment is as follows: the coil generates magnetic force to attract the disc body 2, one end of the rubber ring 3 is embedded in the placement ring groove 141, and the other end of the rubber ring 3 is embedded in the limiting ring groove 22. The elastic force of the first spring 6 causes the pressing block 5 to press against the rubber ring 3, and the rubber ring 3 to press against the rubber pad 4. The centrifugal force generated by the rotation of the disc body 2 causes the pressing block 5 to further apply force to the rubber ring 3, so that the disc body 2 and the wheel body 1 rotate stably and synchronously. After the coil is de-energized, the elastic force of the second spring 8 causes the metal ring 9 to reset, pushing the rubber ring 3 away from the limiting ring groove 22, so that the disc body 2 and the wheel body 1 can be separated in time.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
