DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] Figure 1 is a schematic three-dimensional diagram of the present application, Figure 2 This is a reference diagram of the cage and needle roller in exploded state. Figure 1 and Figure 2 A needle roller bearing installation device includes a loading unit 1, a feeding unit 2 and a needle loading unit 3. The loading unit 1 includes a vibrating loading tray 11, a spiral support plate 110 is provided on the inner wall of the vibrating loading tray 11, and a plurality of retainers 4 to be loaded with needles are installed in the vibrating loading tray 11. The retainer 4 includes an inner ring 41 and an outer ring 42, and a plurality of spring sheets 43 are arranged between the inner ring 41 and the outer ring 42. An installation space is formed between two adjacent spring sheets 43, and a needle roller 5 needs to be installed in each installation space. Since the inner ring 41 is arranged on the inner side of the outer ring 42, one end face of the inner ring 41 protrudes to the outside of one end face of the outer ring 42. In this way, under the vibration of the vibrating loading tray 11, the bottom of the outer ring 42 contacts the top of the support plate 110, and the other end face of the outer ring 42 fits the inner wall of the vibrating loading tray 11. The support plate 110 is vertically connected to the inner wall of the vibrating loading tray 11. By reasonably selecting the width of the support plate 110, it is ensured that when the end face of the inner ring 41 contacts the inner wall of the vibrating loading tray 11, the retaining frame 4 will fall from the support plate 110. In this way, a plurality of retaining frames 4 can be moved in the same direction toward the discharge end of the vibrating loading tray 11 in an orderly manner, thereby realizing reliable loading of the retaining frames 4.

[0034] Figure 3 This is a reference diagram of the assembly status of the feeding unit and the needle unit. Figure 3 Combined with Figure 1 The feeding unit 2 includes a transverse feeding plate 21 and a vertical feeding plate 22. The transverse feeding plate 21 is located between the vibrating loading plate 11 and the vertical feeding plate 22. A feeding channel 210 is provided in each of the transverse feeding plate 21 and the vertical feeding plate 22. The feeding channel 210 is adapted to the retaining frame 4, ensuring that the retaining frame 4 does not change its posture during the movement in the feeding channel 210. The front end of the feeding channel 210 of the transverse feeding plate 21 is connected to the discharge end of the vibrating loading plate 11, and the end of the feeding channel 210 of the transverse feeding plate 21 is connected to the front end of the feeding channel 210 of the vertical feeding plate 22. A feeding fixture 24 is provided at the end of the vertical feeding plate 22. At the same time, a second cylinder 25 is provided on the outer side of the vertical feeding plate 22, and a push plate 26 is inserted into the feeding channel 210 of the vertical feeding plate 22. After the retainer 4 is transported from the feeding channel 210 of the horizontal feeding plate 21 to the feeding channel 210 of the vertical feeding plate 22, the second cylinder 25 drives the push plate 26 to move, and then the push plate 26 reciprocates in the feeding channel 210 of the vertical feeding plate 22 to push the retainer 4 onto the feeding fixture 24. After the retainer 4 is clamped by the feeding fixture 24, the first cylinder 23 under the vertical feeding plate 22 starts to move, thereby reliably transporting the retainer 4 to the needle loading unit 3.

[0035] Furthermore, an upper sensor 27 and a lower sensor 28 are provided on the outer wall of the second cylinder 25. The upper sensor 27 is used to collect signals when the retaining frame 4 moves from the feeding channel 210 of the horizontal feeding plate 21 to the feeding channel 210 of the vertical feeding plate 22. That is to say, when the retaining frame 4 exists in the feeding channel 210 of the vertical feeding plate 22, the upper sensor 27 can collect this signal. After receiving this signal through the signal line, the controller determines that the push plate 26 can be driven. The lower sensor 28 is used to collect the signal when the retaining frame 4 moves from the feeding channel 210 of the vertical feeding plate 22 to the feeding fixture 24. That is to say, when the push plate 26 is moved into place and the retaining frame 4 is securely clamped on the feeding fixture 24, the lower sensor 28 can collect this signal. After the controller receives this signal through the signal line, it determines that the push plate 26 can be retracted. In this way, through the cooperation of the upper sensor 27 and the lower sensor 28, it is ensured that the extension and retraction of the second cylinder 25 can form a reciprocating drive of the push plate 26, thereby realizing a reliable clamping of the retaining frame 4 on the feeding fixture 24.

[0036] See also Figure 2 and Figure 3 The needle loading unit 3 includes a limit plate 31, an abutment seat 32 and a needle roller release seat 33. A baffle 38 is also provided between the limit plate 31 and the abutment seat 32. A through hole 380 is provided in the middle of the baffle 38. The distance between the baffle 38 and the limit plate 31 is not less than the thickness of the feeding clamp 24. The inner diameter of the through hole 380 is larger than the outer diameter of the abutment head 35 and smaller than the outer diameter of the retaining frame 4. When the first cylinder 23 drives the feeding clamp 24 and the retaining frame 4 to move toward the needle loading unit 3, the feeding clamp 24 will move between the baffle 38 and the limit plate 31, thereby ensuring that the retaining frame 4 will not fall off the feeding clamp 24. When the feeding clamp 24 is moved into place, the third cylinder 34 will push the abutment seat 32 and the abutment head 35 close to the feeding clamp 24. During this process, the abutment seat 32 is always located on the outside of the baffle 38, and the abutment head 35 is arranged on the side of the abutment seat 32 close to the baffle 38 and the limit plate 31. The abutment head 35 can pass through the through hole 380 and move to the inside of the baffle 38. After the abutment head 35 moves to the inner side of the baffle 38, the abutment head 35 will be inserted into the inner ring 41 of the retaining frame 4, thereby fixing the retaining frame 4. At this time, the first cylinder 23 is reset to realize the separation of the retaining frame 4 and the feeding clamp 24, and the retaining frame 4 can also complete the transfer from the loading unit 1 to the needle loading unit 3.

[0037] Figure 4 is a schematic three-dimensional diagram of the needle roller release seat. Figure 4 Combined with Figure 2 and Figure 3When the retainer 4 is fixed on the abutment joint 35, the retainer 4 is just located below the needle roller release seat 33. A needle roller 5 delivery pipe 331 is provided on the top of the needle roller release seat 33, and a needle moving block 332 is provided at the bottom of the needle roller release seat 33. The needle roller release seat 33 is connected to the air source, and the air source delivers high-pressure gas into the needle roller release seat 33. Under the push of the gas, the needle roller 5 can move from the needle roller 5 delivery pipe 331 to the needle moving block 332 and be blown by the needle moving block 332 to the installation position of the retainer 4, thereby realizing the needle installation operation of the retainer 4. A toggle rod 36 and a fourth cylinder 37 are provided on the outside of the abutment seat 32. The fourth cylinder 37 drives the toggle rod 36 to reciprocate in a vertical plane. A gear rack or similar transmission mechanism can be provided between the push rod of the fourth cylinder 37 and the toggle rod 36. In this way, the linear drive of the fourth cylinder 37 can be converted into the rotation of the toggle rod 36, ensuring that the toggle rod 36 is used to toggle the retainer 4 and the abutment head 35 to rotate around their own axis. When the toggle rod 36 toggle the retainer 4 to rotate, several installation spaces on the retainer 4 will rotate to the bottom of the needle block 332 in sequence, so that several needle rollers 5 can be blown onto the retainer 4 in sequence, so that all installation spaces on the retainer 4 are filled with a needle roller 5. In this way, it is only necessary to manually put the retainer 4 into the vibrating loading tray 11 and the needle roller 5 into the needle roller release seat 33 to realize the automatic needle installation operation of the needle roller 5 on the retainer 4, which effectively improves the overall work efficiency.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
