[0032] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely exemplary embodiments of this utility model, and not the only embodiments.

[0033] See Figures 1 to 11 The assembly equipment for valve body shaft spring retainer includes an assembly table 1. A rotating disk 2 is rotatably mounted on the upper middle part of the assembly table 1. A base 4 for placing aluminum shaft 5 is placed on the rotating disk 2. The base 4 is provided with a slot 400 for placing aluminum shaft 5. The rotating disk 2 is provided with multiple work station slots 3. When the base 4 rotates on the rotating disk 2 to the corresponding work station slot 3, the corresponding processing operation is performed.

[0034] On the assembly table 1, around the side of the rotating disk 2, there are sequentially installed aluminum shaft 5 mounting mechanisms for mounting aluminum shaft 5 and snap ring 17 mounting mechanisms for mounting snap ring 17 on aluminum shaft 5.

[0035] The aluminum shaft 5 mounting mechanism includes a gripping mechanism connected to a first conveying groove 6 for conveying the aluminum shaft 5. The gripping mechanism includes a first lifting cylinder 7 that can move up and down. The first lifting cylinder 7 is connected to a first translating cylinder 8 that can drive the first lifting cylinder 7 to move horizontally. A first clamp 9 is mounted at the bottom of the first lifting cylinder 7 for gripping the aluminum shaft 5 and moving it onto the base 4. Besides gripping the aluminum shaft 5, the first clamp 9 also has another function: in actual use, when the aluminum shaft 5 already has a retaining ring 17 installed, it may still move along the first conveying groove... 6. During the installation process of aluminum shaft 5, when the first gripper 9 grasps the aluminum shaft 5 with retaining ring 17, the retaining ring 17 will lock into itself with the first gripper 9, causing the assembly equipment to stop and alarm. This prevents the aluminum shaft 5 with retaining ring 17 from proceeding to subsequent processes. The aluminum shaft 5 installation mechanism also includes a first propulsion assembly perpendicular to the first lifting cylinder 7. The first propulsion assembly includes a first drive cylinder 10 and a first fixing plate 11 located at the bottom of the first drive cylinder 10. The end of the first drive cylinder 10 is fixedly connected to the first... A push rod 12 is mounted on a first fixed plate 11, through which a first baffle 13 is installed. A feed chute 14 is formed at one end of the first baffle 13 near the first conveying chute 6. The feed chute 14 receives aluminum shafts 5 from the first conveying chute 6. A semi-circular groove 15, adapted to the outer circumference of the aluminum shaft 5, is provided inside the first push rod 12. The semi-circular groove 15 and the feed chute 14 are adapted to each other. Before installing the aluminum shaft 5, a first drive cylinder 10 pushes the first push rod 12 towards a first lifting cylinder 7, aligning the semi-circular groove 15 with the feed chute 14. The aluminum shaft 5 is then leveled, allowing it to enter the semi-arc groove 15 along the feed chute 14. The semi-arc groove 15 can fix the aluminum shaft 5, preventing it from shaking before being transferred. A limiting plate 16 is installed at the top of the first baffle 13 near the first conveying chute 6 to control the position of the semi-arc groove 15 when the first push rod 12 moves along the direction of the first lifting cylinder 7. This is to prevent the semi-arc groove 15 from being uneven with the feed chute 14 when the first push rod 12 moves along the direction of the first lifting cylinder 7, thus affecting the entry of the aluminum shaft 5 into the semi-arc groove 15.

[0036] The installation process of aluminum shaft 5 is as follows: aluminum shaft 5 enters the semi-arc groove 15 through the first conveying groove 6 along the feeding groove 14. The first lifting cylinder 7 descends down to the first gripper 9 to pick up aluminum shaft 5 and moves it under the drive of the first translation cylinder 8 to the base 4 above the corresponding work station groove 3 that has been rotated with the rotating disk 2. The first lifting cylinder 7 continues to descend down to the slot 400 on the base 4 where aluminum shaft 5 is installed.

[0037] The circlip 17 mounting mechanism includes a clamping mechanism connected to a second conveying groove 18 for conveying the circlip 17. The clamping mechanism includes a second lifting cylinder 19 that can move up and down. The second lifting cylinder 19 is connected to a second translating cylinder 20 that can drive the second lifting cylinder 19 to translate. A suction tube 21 for picking up the circlip 17 and mounting it onto the aluminum shaft 5 is mounted on the second lifting cylinder 19. The clamping mechanism also includes a second propulsion assembly perpendicular to the first translating cylinder 8. The second propulsion assembly includes a second driving cylinder 22 and a second fixing plate 23 located at the bottom of the second driving cylinder 22. A second push rod 24 is fixedly connected to the end of the second driving cylinder 22. A second baffle 25 through which the second push rod 24 can pass is mounted on the second fixing plate 23. The second baffle 25 is close to the second conveying groove 18. A feeding groove 26 is provided at one end, and a groove 27 adapted to the retaining ring 17 is provided in the second push rod 24. The groove 27 is adapted to the feeding groove 26. Before installing the retaining ring 17, the second drive cylinder 22 pushes the second push rod 24 in the direction of the second lifting cylinder 19 so that the groove 27 is flush with the feeding groove 26. In this way, the retaining ring 17 enters the groove 27 along the feeding groove 26. The groove 27 can fix the retaining ring 17 and prevent it from moving before being transferred. A limiting member 28 with a limiting rod 29 is installed on the second baffle 25. The limiting rod 29 vertically passes through the limiting member 28 and abuts against the inside of the feeding groove 26. This setting is to prevent the retaining ring 17 from detaching from the feeding groove 26 when it enters the feeding groove 26. The limiting rod 29 can block the retaining ring 17 and prevent it from detaching from the feeding groove 26.

[0038] The installation process of the retaining ring 17 is as follows: the retaining ring 17 enters the retaining groove 27 through the second conveying groove 18 along the feeding groove 26. The second lifting cylinder 19 descends down to the suction pipe 21 to adsorb the retaining ring 17 and moves it to the aluminum shaft 5 above the base 4 that has been rotated to the corresponding work station groove 3 with the rotating disk 2 under the drive of the second translation cylinder 20. The second lifting cylinder 19 continues to descend down to the retaining ring 17 and it falls onto the aluminum shaft 5.

[0039] Furthermore, a spring 33 mounting mechanism for mounting the spring 33 on the aluminum shaft 5 is also installed between the aluminum shaft 5 mounting mechanism and the retaining ring 17 mounting mechanism. The spring 33 mounting mechanism includes a third lifting cylinder 30 that can move up and down. The third lifting cylinder 30 is connected to a third translation cylinder 31 that can drive the third lifting cylinder 30 to translate. A second gripper 32 for gripping the spring 33 and mounting the spring 33 on the aluminum shaft 5 is installed at the bottom of the third translation cylinder 31.

[0040] The installation process of spring 33 is as follows: the third translation cylinder 31 drives the third lifting cylinder 30 to move towards the base 4, which has been rotated to the corresponding work station slot 3 with the rotary disk 2, until the second gripper 32 is above the aluminum shaft 5. The third lifting cylinder 30 then descends to the spring 33 and is sleeved on the aluminum shaft 5.

[0041] Furthermore, a valve body 44 mounting mechanism is also installed between the spring 33 mounting mechanism and the retaining ring 17 mounting mechanism for mounting the valve body 44. The valve body 44 mounting mechanism includes a fourth lifting cylinder 34 that can move up and down. The fourth lifting cylinder 34 is connected to a fourth translation cylinder 35 that can drive the fourth lifting cylinder 34 to move horizontally. A clamping mechanism 36 for gripping the valve body 44 and mounting the valve body 44 on the base 4 is installed on the fourth lifting cylinder 34. The valve body 44 includes a valve hole 45 and a limiting hole 46 for sleeved aluminum shaft 5. The valve body 44 and aluminum shaft 5 are joined together by the limiting hole 46. The clamping mechanism 36 includes... The clamping mechanism 36 includes a third clamp 37 and a sleeve 38 disposed within the third clamp 37. The sleeve 38 is adapted to the valve hole 45. The clamping mechanism 36 also includes an auxiliary plate 39 arranged in a cross shape with the third clamp 37. A magnetic rod 40 adapted to the limiting hole 46 is installed at the bottom of the auxiliary plate 39. The valve body 44 mounting mechanism also includes a positioning plate 41 arranged perpendicularly to the third translation cylinder 31. A limiting sleeve 42 adapted to the valve hole 45 is installed on the positioning plate 41. A limiting shaft 43 adapted to the limiting hole 46 is installed on the side of the limiting sleeve 42. The purpose of the limiting sleeve 42 and the limiting shaft 43 is to keep the valve body 44 in a stable position before it is transferred.

[0042] The installation process of valve body 44 is as follows: the fourth lifting cylinder 34 descends to the sleeve 38 of the third gripper 37 and extends into the valve hole 45. At the same time, the magnetic rod 40 extends into the limiting hole 46. The fourth lifting cylinder 34 rises until the valve body 44 is separated from the valve body 44 positioning plate 41. The fourth translation cylinder 35 drives the fourth lifting cylinder 34 to move above the base 4 on the corresponding work station slot 3, which has been rotated with the rotating disk 2. The fourth lifting cylinder 34 descends to allow the aluminum shaft 5 to pass through the limiting hole 46, completing the combination of valve body 44 and aluminum shaft 5, and thus completing the installation of valve body 44.

[0043] Furthermore, a circlip 17 detection mechanism is installed on the side of the assembly table 1 around the rotating disk 2 to detect whether the circlip 17 is installed on the aluminum shaft 5. The circlip 17 detection mechanism includes a fifth lifting cylinder 47 that can move up and down. A fourth gripper 48 is fixedly installed at the bottom of the fifth lifting cylinder 47. The fourth gripper 48 holds a probe 49 for detecting whether the circlip 17 is installed on the aluminum shaft 5. The probe 49 is electrically connected to an external sensing device. The fifth lifting cylinder 47 descends to the probe 49 and above the aluminum shaft 5, which has been rotated with the rotating disk 2 to the base 4 of the corresponding workstation slot 3. When the probe 49 senses that there is no circlip 17 on the aluminum shaft 5, it will issue a sensing information to remind that no circlip 17 is installed on the aluminum shaft 5 and that the circlip 17 needs to be reinstalled on the aluminum shaft 5.

[0044] Furthermore, after the installation of the aluminum shaft 5, spring 33, valve body 44, and retaining ring 17 are completed and passed the inspection by the retaining ring 17 detection mechanism, the assembled valve body 44 needs to be unloaded. Therefore, a discharge mechanism for outputting the assembled valve body 44 is also installed on the assembly table 1 around the side of the rotating disk 2. The discharge mechanism includes a sixth lifting cylinder 50, which is connected to a fifth translation cylinder 51 that can drive the sixth lifting cylinder 50 to translate. A fifth gripper 52 for gripping the base 4 is fixedly installed at the bottom. The discharge mechanism also includes a discharge trough 53 set below the fifth gripper 52. The specific discharge process is as follows: the sixth lifting cylinder 50 descends to the fifth gripper 52 to grip the valve body 44 that has been rotated to the corresponding work station 3 with the rotary disk 2. The fifth translation cylinder 51 drives the sixth lifting cylinder 50 to move towards the discharge trough 53. The sixth lifting cylinder 50 then descends to the fifth gripper 52 to drop the valve body 44 into the discharge trough 53, thus completing the discharge of the valve body 44.

[0045] The assembly equipment has a container for placing aluminum shafts 5 installed on one side of the first conveying channel 6, and a container for placing retaining rings 17 installed on one side of the second conveying channel 18. The assembly equipment also includes an operating system for controlling the operation of the entire equipment, such as a controller and a display screen.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
