[0035] In order to make the purpose, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with specific embodiments.

[0036] Such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 ,Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown in Figure 6 , Figure 7 , Figure 8 and Figure 9 , an automatic assembling device for an axial C-ring includes an assembling table 7, and a tooling fixture 45 for clamping a workpiece shaft is installed on the assembling table 7. A moving module 4 is arranged between the tooling fixture 45 and the assembling table 7. The moving module 4 includes a transverse cylinder 43, and the output end of the transverse cylinder 43 is connected to the tooling fixture 45. A vertical cylinder 44 is installed at the middle of the assembling table 7, and the transverse cylinder 43 and the tooling fixture 45 are installed on the output end of the vertical cylinder 44;

[0037] Vibratory bowls 6 are installed on both sides of the assembling table 7. A ramp 9 is installed outside the vibratory bowls 6. Feeding devices 2 for conveying the rings are arranged at the ends of the ramp 9 on both sides of the moving module 4. A transfer structure 8 is arranged at the outlet of the feeding device 2. The transfer structure 8 includes a second sleeve 42 sleeved on the workpiece shaft. The transfer structure 8 transfers the ring to the outside of the workpiece shaft of the second sleeve 42;

[0038] An installation structure 1 is further arranged on one side of the feeding device 2. The installation structure 1 includes a first sleeve 11. The installation structure 1 pushes the ring through the second sleeve 42 and installs it at a specified position in the workpiece shaft;

[0039] Detection structures 3 are arranged on both sides at the other end of the moving module 4 and on the assembling table 7. The detection structures 3, the feeding devices 2, the installation structures 1 and the transfer structures 8 are all installed on the assembling table 7. The detection structures 3 are used to detect the position of the ring on the workpiece shaft.

[0040] In this embodiment, the C-ring is placed inside the vibratory bowl 6, and the workpiece 41 is placed in the tooling fixture 45. The vibratory bowl 6 is used to transfer the ring through the ramp 9 into the feeding device 2. The feeding device 2 conveys the ring. After the ring is conveyed to the outlet of the feeding device 2, after being sleeved with the second sleeve 42 in the transfer structure 8, under the action of the transfer structure 8, the second sleeve 42 moves horizontally, so that the second sleeve 42 sleeved with the ring is clamped on both sides of the workpiece shaft of the workpiece 41;

[0041] Then, the vertical cylinder 44 in the moving module 4 is used to drive the workpiece 41 and the second sleeve 42 to move to one side of the installation structure 1. The first sleeve 11 in the installation structure 1 is used to push the ring outside the second sleeve 42 until the ring is clamped at a specified position in the workpiece shaft of the workpiece 41. After the installation structure 1 returns, the moving module 4 continues to move, so that the detection structure 3 detects the position of the ring. During the automatic assembly of the ring, the functions of feeding, assembling and detecting are integrated. There is no need to manually sleeve the ring. While improving the assembly efficiency, it can adapt to the situation where a large number of workpiece shafts need to be sleeved with rings, and improve the installation speed and accuracy rate of the ring.

[0042] As an embodiment, asFigure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown in Figure 4 , Figure 5 , the feeding device 2 includes a retaining ring conveying groove 21 slidably mounted at the end of the ramp 9. A first photoelectric sensor 22 is provided on the retaining ring conveying groove 21, and a feeding plate 27 is installed at the end of the retaining ring conveying groove 21. An arc-shaped channel 28 is formed inside the feeding plate 27. A feeding plate 24 is slidably mounted on one side of the feeding plate 27. The bottom end of the feeding plate 24 is connected to the output end of the second cylinder 23. The second cylinder 23 is fixedly installed on the assembly table 7;

[0043] The two sides of the feeding plate 27 are both provided with a second photoelectric sensor 25 and a third photoelectric sensor 26.

[0044] Among them, an arc-shaped groove corresponding to the arc-shaped channel 28 is formed inside the feeding plate 24, and a U-shaped hole for the sleeve two 42 to penetrate is formed in the arc-shaped groove.

[0045] As an implementation manner, as Figure 1 , Figure 2 and Figure 3 shown, both the second photoelectric sensor 25 and the third photoelectric sensor 26 are electrically connected to the second cylinder 23. One end of the sleeve two 42 is a trapezoidal cylinder, and a stepped hole matching the workpiece shaft is provided inside the sleeve two 42 to axially control the installation position of the sleeve two 42. The retaining ring inside the U-shaped hole of the feeding plate 24 can be conveniently and quickly inserted through the trapezoidal cylinder.

[0046] In this implementation manner, the retaining ring enters the inside of the retaining ring conveying groove 21 through the ramp 9. When feeding the retaining ring on the retaining ring conveying groove 21, the second photoelectric sensor 25 and the third photoelectric sensor 26 are used to detect whether there is a retaining ring in the arc-shaped channel 28. The second photoelectric sensor 25 detects whether there is a retaining ring in the feeding plate 24 at the bottom of the channel. If there is a retaining ring, the second cylinder 23 works to eject the retaining ring in the feeding plate 24. The third photoelectric sensor 26 detects whether the ejected retaining ring is taken away by the sleeve two 42. After being taken away, the second cylinder 23 retracts to complete the intermittent feeding of the retaining ring, which is suitable for the installation of a large number of retaining rings and shafts.

[0047] As an implementation manner, as Figure 1 , Figure 5 and Figure 6 shown, the transfer structure 8 further includes a fifth cylinder 81 installed on the assembly table 7. The output end of the fifth cylinder 81 is fixedly connected with a connecting piece 82. A pneumatic gripper 83 is arranged inside the connecting piece 82. The pneumatic gripper 83 is used to grip the sleeve two 42.

[0048] In this embodiment, the fifth cylinder 81 drives the connecting member 82 to move, and the pneumatic clamp 83 on the connecting member 82 clamps the sleeve 42 to move toward the feed plate 27 first. After one end of the sleeve 42 passes through the interior of the feed plate 24, a retaining ring is sleeved on it, and then the fifth cylinder 81 drives the pneumatic clamp 83 on the connecting member 82 to move toward the workpiece 41, and engages with the workpiece 41 to complete the transfer of the retaining ring, without the need for manual sleeved retaining ring.

[0049] As an implementation method, Figure 1 , Figure 5 and Figure 6 As shown, the mounting structure 1 also includes a first cylinder 14, the output end of the first cylinder 14 is fixedly connected to a sleeve 11, one side of the sleeve 11 is connected to a limiting shaft 12, and the end of the limiting shaft 12 is sleeved with a shaft sleeve 13.

[0050] In this embodiment, when the vertical cylinder 44 drives the workpiece 41 and the sleeve 2 42 to move to one side of the mounting structure 1, the first cylinder 14 drives the sleeve 11 to be inserted into the outside of the sleeve 2 42, pushing the retaining ring outside the sleeve 2 42, and limiting the position using the limiting shaft 12 and the sleeve 13 until the retaining ring is engaged with the specified position of the workpiece shaft of the workpiece 41, thereby completing the assembly of the retaining ring and the workpiece shaft.

[0051] As an implementation method, Figure 1 , Figure 2 and Figure 9 As shown, the detection structure 3 includes a work plate 37, a third cylinder 31 is fixedly mounted on the top of the work plate 37, and a contact head 35 is mounted on the output end of the third cylinder 31. The contact head 35 corresponds to the workpiece and is used for radial fixing of the workpiece;

[0052] A detection clamp 34 is installed on the inner side of the working plate 37, a compression spring 33 is connected to the bottom end of the detection clamp 34, a contact sensor 32 is fixedly installed on the top end of the detection clamp 34, and a photoelectric sensor 36 electrically connected to the fifth cylinder 81 is installed on one side of the working plate 37.

[0053] The opening of the detection jaw 34 is smaller than the outer diameter of the retaining ring, and the opening of the detection jaw 34 is larger than the outer portion of the workpiece shaft.

[0054] In this embodiment, the photoelectric sensor 4 36 works first. The photoelectric sensor 4 36 is used to detect whether the sleeve 2 42 covers the retaining ring installation groove. When the sleeve 11 is pushed to the predetermined position, the internal stepped hole of the sleeve 2 42 contacts the end of the workpiece shaft for axial limitation, preventing the sleeve 2 42 from moving axially on the workpiece shaft and covering the groove when the sleeve 11 pushes the retaining ring.

[0055] After the retaining ring and the workpiece shaft are assembled, the vertical cylinder 44 continues to drive the workpiece 41 and the retaining ring on the second sleeve 42 to move until the retaining ring enters the inside of the detection jaw 34. After the tip of the detection jaw 34 touches the retaining ring, the jaw naturally opens, the contact sensor 32 disconnects the contact, and the pressure value is zero, indicating that the retaining ring is installed in place. When it is installed in place, it directly returns to the feeding position, and the worker removes the workpiece for the next process; on the contrary, if the contact sensor value does not return to zero after the workpiece reaches the detection position, it means that the retaining ring is not installed in place. If it is not installed in place, it also returns to the worker's front. The worker checks the problem, but when putting in the next workpiece, the machine will still continue to work and will not report an error and stop due to improper installation. The detection signal for detecting whether the installation is in place is mainly to facilitate the worker to find defective parts.

[0056] As an implementation manner, as Figure 1 , Figure 7 and Figure 3 shown, the inner diameter of the first sleeve 11 is larger than the outer diameter of the second sleeve 42, and the second sleeve 42 and the feeding plate 24 are arranged corresponding to each other.

[0057] In this implementation manner, after the first sleeve 11 is sleeved with the second sleeve 42, one end of the first sleeve 11 drives the external retaining ring to move towards the workpiece shaft direction, keeping the retaining ring sleeved on the workpiece shaft in a complete state.

[0058] First, the vertical cylinder 44 drives the workpiece 41 and the second sleeve 42 to reach the installation position, then the third cylinder 31 drives the contact head 35 to radially fix the workpiece, and the first cylinder 14 drives the first sleeve 11 to be installed. When the first cylinder 14 stops, the first sleeve 11 stops pushing in. By controlling the length of the first sleeve and the stroke of the cylinder, the installation position of the retaining ring on the workpiece shaft is adjusted. Different lengths of the first sleeve can be applied to the installation of retaining rings at different axial positions on the shaft.

[0059] As an implementation manner, as Figure 1 and Figure 6 shown, on one side of the moving module 4 and at the bottom of the installation structure 1, the feeding device 2, the detection structure 3, and the transfer structure 8, an adjusting device 5 is fixedly installed. The adjusting device 5 includes a fourth cylinder 51, and the output end of the fourth cylinder 51 is fixedly connected with a bottom plate 52. A guide rail 53 is installed between the bottom plate 52 and the assembly table 7.

[0060] In this implementation manner, when there are workpieces of different lengths or different installation positions on different workpieces, the workpiece 41 is placed on the tooling fixture 45. The fourth cylinder 51 drives the bottom plate 52 to move, and the transfer structure 8 and the detection structure 3 on the bottom plate 52 move accordingly, changing the installation positions at different depths. It can also detect the installation situation of the retaining ring on workpieces with different specifications of workpiece shafts through the detection structure 3.

[0061] Working principle: During use, place the C-shaped retaining ring inside the vibrating bowl 6, and place the workpiece 41 in the tooling fixture 45. Use the vibrating bowl 6 to transfer the retaining ring to the inside of the feeding device 2 through the ramp 9. The retaining ring enters the retaining ring conveying groove 21 through the ramp 9. When feeding the retaining ring on the retaining ring conveying groove 21, the first photoelectric sensor 22 is triggered, and the retaining ring enters the arc-shaped channel 28 in the feeding plate 27, triggering the second photoelectric sensor 25 and the third photoelectric sensor 26. After passing through the arc-shaped channel 28, it enters the inside of the feeding plate 24, and the second cylinder 23 pushes the retaining ring inside the feeding plate 24 upward;

[0062] At the same time, after the retaining ring is conveyed to the outlet of the feeding device 2, the fifth cylinder 81 drives the connecting piece 82 to move. The pneumatic gripper 83 on the connecting piece 82 clamps the second sleeve 42 and first moves towards the feeding plate 27. After one end of the second sleeve 42 penetrates the inside of the feeding plate 24, it sleevs the retaining ring. Then, the fifth cylinder 81 drives the pneumatic gripper 83 on the connecting piece 82 to move towards the workpiece 41. The fifth cylinder 81 drives the pneumatic gripper 83 and the second sleeve 42 to move horizontally and sleeve onto the workpiece shaft, and is clamped with the workpiece 41 to complete the transfer of the retaining ring, so that the second sleeve 42 sleeving the retaining ring is clamped on both sides of the workpiece shaft of the workpiece 41;

[0063] Then, use the vertical cylinder 44 in the moving module 4 to drive the workpiece 41 and the second sleeve 42 to move to one side of the installation structure 1. First, use the third cylinder 31 to drive the contact head 35 to radially fix the workpiece. Before the first sleeve 11 is pushed to the predetermined position, the fourth photoelectric sensor 36 works first. The fourth photoelectric sensor 36 is used to detect whether the second sleeve 42 covers the retaining ring installation groove. When the first sleeve 11 is pushed to the predetermined position, the stepped hole inside the second sleeve 42 contacts the shaft end for axial limit, preventing the second sleeve 42 from axially moving on the workpiece shaft and covering the groove when the first sleeve 11 pushes the retaining ring. Thus, the first cylinder 14 drives the first sleeve 11 to insert outside the second sleeve 42 and push the retaining ring outside the second sleeve 42, and uses the limit shaft 12 and the bushing 13 for limit until the retaining ring is clamped to the specified position in the workpiece shaft of the workpiece 41, completing the assembly of the retaining ring and the workpiece shaft;

[0064] After the assembly of the retaining ring and the workpiece shaft is completed, the vertical cylinder 44 continues to drive the workpiece 41 and the retaining ring on the second sleeve 42 to move until the retaining ring enters the inside of the detection gripper 34. After the tip of the detection gripper 34 touches the retaining ring, the gripper naturally opens, and the contact sensor 32 disconnects the contact and the pressure value is zero, indicating that the retaining ring is installed in place. On the contrary, if the contact sensor value does not return to zero after the workpiece reaches the detection position, it means that the retaining ring is not installed in place;

[0065] After the detection is correct, the installed workpiece 41 moves back with the vertical cylinder 44, reaches the feeding position, the pneumatic gripper 83 clamps the second sleeve 42 and removes it from the workpiece shaft, and the worker takes out the assembled workpiece 41 and places it on the fixture 45 to perform the next process, ending the entire installation process. During the automatic assembly of the retaining ring, the feeding, assembly and detection are integrated. There is no need to manually socket the retaining ring. While improving the assembly efficiency, it can adapt to the retaining ring assembly work of a large number of shaft workpieces, and improve the installation speed and accuracy of the retaining ring.
