Description

Technical Field

[0001] This application relates to the technical field of full-automatic bearing assembly, and particularly to a new type of full-automatic assembly machine for full-needle bearings. Background Art

[0002] Full-needle bearings usually refer to full complement cylindrical roller bearings, which belong to a special type of rolling bearings. Compared with common types of bearings, the structural feature of full-needle bearings is that there is no cage, and the number of rollers, i.e., needle rollers, installed between the inner ring and the outer ring of the bearing is more. This enables full-needle bearings to withstand greater radial loads and have higher load-carrying capacity and rigidity. Full-needle bearings are often widely used in the field of industrial machinery, such as in the transmissions and differentials of automobiles. On the one hand, they can have a large radial load-carrying capacity, and on the other hand, due to the absence of a cage, their overall size can be designed smaller.

[0003] Generally, a bearing includes an outer ring, an inner ring, a certain number of needle rollers, a cage, and a seal. During assembly, usually, the needle rollers are first installed on a certain component, usually the cage, and then the assembly of other components is carried out. Existing general-purpose bearing assembly machines generally include a distribution disk and clamping devices and needle-loading devices distributed around the indexing disk. First, the cage is clamped by the clamping device, and then multiple needle rollers are sequentially driven into the cage along the radial direction of the cage by the needle-loading device. Since the cage has the ability to deform and the pocket holes on the cage have the ability to restrain the needle rollers, the needle rollers will be locked by the pocket holes on the cage and have a reliable position.

[0004] Since the full-needle bearing does not have the part of the cage, when loading the needle rollers, multiple needle rollers need to be directly driven into the outer ring one by one. The outer ring has a flange to prevent the needle rollers from falling along the axis direction of the outer ring. However, when using the above-mentioned needle-loading device for loading the needle rollers, since the outer ring does not restrict the circumferential movement ability of each needle roller, the needle rollers driven into the outer ring may be inclined, and the positions of the needle rollers are unreliable, which results in the bearing assembly not meeting the requirements. Summary of the Invention

[0005] In order to drive multiple needle rollers into the outer ring and ensure the reliable positions of the multiple needle rollers, this application provides a new type of full-automatic assembly machine for full-needle bearings.

[0006] The new type of full-automatic assembly machine for full-needle bearings provided by this application adopts the following technical solutions: A new type of full-automatic assembly machine for full-needle bearings includes a frame. The frame is equipped with a rotary feeding device, and the frame is also equipped with a feeding device for feeding the outer ring to the rotary feeding device, a grease-uniforming device for uniformly attaching grease to the inner wall of the outer ring, a needle-loading device for installing needle rollers on the outer ring, and a discharging device for discharging the outer ring. The grease uniforming device includes a frame body arranged on a frame, and the frame body is equipped with a receiving and rotating component, a material moving component and a grease spraying component. The material moving component is configured to be able to move the outer ring into or leave the receiving and rotating component, and the grease spraying component is configured to be able to spray grease onto the inner wall of the outer ring. The receiving and rotating component is configured to be able to drive the outer ring to rotate so that the grease is evenly distributed on the inner wall of the outer ring.

[0007] By adopting the above technical scheme, the following actions can be achieved: first, the outer ring is loaded onto the rotary feeding device by using the loading device, and then the rotary feeding device is driven to drive the outer ring to the grease distribution device and the needle loading device in turn, so as to evenly adhere grease to the inner wall of the outer ring and drive the roller needle into the outer ring in turn, and then the rotary feeding device drives the outer ring with the roller needle to the side of the discharging device for unloading; wherein, the specific action of the grease distribution device is: when the outer ring reaches one side of the material transfer component, the material transfer component is driven to move the outer ring into the receiving rotating component, and then the grease spraying component is used to spray the grease onto the inner wall of the outer ring, at which time the grease is in a condensed state, and then the receiving rotating component is driven to drive the outer ring to rotate so that the condensed grease is evenly thrown on the inner wall of the outer ring.

[0008] In the present application, since there is grease on the inner wall of the outer ring, the needle roller will come into contact with the grease after being driven into the inner wall of the outer ring. The grease will restrict the position of the needle roller to a certain extent. At this time, the needle roller is difficult to fall and difficult to tilt without being subjected to a large external force. After the inner wall of the outer ring is gradually filled with needle rollers, the positions of multiple needle rollers are more reliable.

[0009] Preferably, the receiving rotating assembly includes a belt rotating member installed on the frame body and a receiving member connected to the belt rotating member, and the receiving member includes a receiving groove at the top end for placing the outer ring.

[0010] By adopting the above technical solution, the outer ring can be placed in the receiving groove, and then the driving belt rotating member can drive the outer ring to rotate.

[0011] Preferably, the material moving assembly includes a material pushing drive member 1 and a material pushing drive member 2 installed on the frame, the material pushing drive member 1 is rotatably connected to a pressure shaft, and the material pushing drive member 2 is connected to a supporting shaft, and the pressure shaft and the supporting shaft are respectively located on both sides of the receiving groove; the belt rotating member is provided with a receiving hole that passes through the receiving groove, and the supporting shaft is inserted into the receiving hole.

[0012] By adopting the above technical solution, on the one hand, the push-up driving member 1 and the push-up driving member 2 can drive the pressing shaft and the supporting shaft to move synchronously to move the outer ring into or out of the receiving groove; on the other hand, in order to prevent grease from flying out when the outer ring rotates, the pressing shaft can maintain the pressure on the outer ring when driving the outer ring to rotate, and the pressing shaft does not separate from the outer ring.

[0014] By adopting the above technical solution, in the present application, to make the grease form a certain position constraint on the needle roller, usually a relatively thick grease needs to be used. This grease will also adhere to the pressing shaft during the process of being evenly distributed. In order to prevent the outer ring from adhering to the pressing shaft and being unable to separate due to the presence of grease when the outer ring is unloaded later, the third ejecting driving member can be driven to drive the ejecting shaft to move and push the outer ring away from the pressing shaft.

[0015] Preferably, the needle loading device includes a mounting frame arranged on the machine frame. A pressing component is mounted on the mounting frame. The pressing component is used to press the outer ring and drive the outer ring to rotate. A needle feeding component and a needle injecting component are also mounted on the mounting frame. The needle feeding component is used to send the needle roller into the outer ring, and the needle injecting component is used to inject the needle roller onto the inner wall of the outer ring.

[0016] By adopting the above technical solution, the following operations can be realized: when the outer ring reaches one side of the pressing component, the pressing component is driven to press the outer ring, then the needle feeding component is driven to send the needle rollers into the outer ring one by one, and then the needle injecting component is driven to inject the needle rollers sent one by one onto the inner wall of the outer ring until it is full.

[0017] Preferably, the pressing component includes a first reciprocating driving member arranged on the mounting frame. The first reciprocating driving member is connected to a first fixing frame. A pressing sleeve is rotatably connected to the first fixing frame. A secondary pressing sleeve is rotatably connected to the mounting frame below the pressing sleeve. The first reciprocating driving member is used to drive the pressing sleeve to move and press the outer ring against the secondary pressing sleeve.

[0018] By adopting the above technical solution, after the outer ring reaches between the secondary pressing sleeve and the pressing sleeve, the first reciprocating driving member is driven to drive the pressing sleeve to move and press the outer ring against the secondary pressing sleeve.

[0019] Preferably, the needle feeding component includes a loading member mounted on the first fixing frame. The loading member includes a feeding channel inside and a feeding port at the top communicating with the feeding channel. The feeding port is connected to a vibrating plate. A second reciprocating driving member is mounted on the loading member. A third reciprocating driving member is also mounted on the mounting frame. The third reciprocating driving member is connected to a needle ejecting shaft. The secondary pressing sleeve is provided with an accommodation through hole for the needle ejecting shaft to pass through. After the vibrating plate transports the needle rollers into the feeding channel, the second reciprocating driving member pushes the needle rollers to one side of the needle ejecting shaft, and the third reciprocating driving member drives the needle ejecting shaft to move and push the needle rollers into the outer ring.

[0020] By adopting the above technical solution, the vibrating disk is used to convey the needle rollers into the feeding channel, the reciprocating driving member II is driven to push the needle rollers to one side of the thimble shaft, the reciprocating driving member III is driven to drive the thimble shaft to move to push the needle rollers into the outer ring, and then the needle injection assembly is driven to inject the needle rollers onto the inner wall of the outer ring.

[0021] Preferably, the needle injection assembly includes a reciprocating driving member IV installed on the first fixing frame, the reciprocating driving member IV is connected with a needle injection member, the needle injection member includes a pressing part, when the needle roller is located in the outer ring, the reciprocating driving member IV drives the needle injection member to move so that the pressing part presses the needle roller into the inner wall of the outer ring; a rotating member is also installed on the mounting frame, the rotating member is connected with a driving gear, the auxiliary pressing sleeve is connected with a driven gear, the driving gear meshes with the driven gear, and the rotating member can drive the auxiliary pressing sleeve to rotate and then drive the outer ring to rotate by driving the driving gear and the driven gear to rotate.

[0022] By adopting the above technical solution, after the needle roller is conveyed into the outer ring, the reciprocating driving member IV is driven to drive the needle injection member to move so as to drive the pressing part to move to press the needle roller into the inner wall of the outer ring. At this time, the injection of one needle roller is completed. Then, the rotating member is driven to drive the driving gear and the driven gear to rotate so as to drive the auxiliary pressing sleeve to rotate and then drive the outer ring to rotate. Then, the above actions are continued to be repeated to complete the injection of the next needle roller until it is full.

[0023] Preferably, the rotary feeding device includes a hollow rotary platform arranged on the machine frame, and a plurality of material holding components are installed on the hollow rotary platform.

[0024] Preferably, the material holding component includes a connecting plate connected to the hollow rotary platform, a through material receiving groove is formed in the connecting plate, a mounting groove is formed in the groove wall of the material receiving groove, a material blocking member is slidably connected to the mounting groove, and a spring is jointly connected between the material blocking member and the mounting groove.

[0025] By adopting the above technical solution, it is convenient to snap the outer ring into the mounting groove, and under the action of the spring, the outer ring will be tightly pressed by the material blocking member at this time.

[0026] In summary, the present invention includes at least one of the following beneficial technical effects: 1. This application can achieve the following operations: First, use the feeding device to feed the outer ring onto the rotary feeding device, and then drive the rotary feeding device to drive the outer ring to reach the grease uniformizing device and the needle loading device in sequence, so as to perform the operations of uniformly attaching grease to the inner wall of the outer ring and driving the needle rollers into the outer ring in sequence. After that, the rotary feeding device drives the outer ring with the needle rollers loaded to reach one side of the discharging device for discharging; among them, the specific operation of the grease uniformizing device is: when the outer ring reaches one side of the material transferring component, drive the material transferring component to move the outer ring into the receiving and rotating component, and then use the grease spraying component to spray the grease onto the inner wall of the outer ring. At this time, the grease is in a condensed state, and then drive the receiving and rotating component to drive the outer ring to rotate so that the condensed grease is evenly spread on the inner wall of the outer ring.

[0027] In this application, since there is grease on the inner wall of the outer ring, after the needle rollers are driven into the inner wall of the outer ring, they will come into contact with the grease. The grease will impose a certain constraint on the position of the needle rollers. At this time, the needle rollers are difficult to fall off and are difficult to tilt without being subjected to a large external force. After the inner wall of the outer ring is gradually filled with needle rollers, the positions of multiple needle rollers are relatively reliable; 2. On the one hand, the top material driving part one and the top material driving part two can drive the pressure shaft and the material supporting shaft to move synchronously to move the outer ring into or out of the receiving groove. On the other hand, in order to prevent the grease from flying out when the outer ring rotates, the pressure on the outer ring by the pressure shaft can be maintained when driving the outer ring to rotate, and the pressure shaft does not separate from the outer ring.

Detailed implementation manners

[0030] The present invention will be further described in detail below with reference to the accompanying drawings.

[0031] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as up, down, front, back, left, right, etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0032] The embodiments of the present application disclose a new type of full-automatic assembly machine for full-needle bearings. It is used to be able to punch a plurality of rolling needles into the outer ring and ensure the reliable positions of the plurality of rolling needles.Figure 1 It is a schematic structural diagram of the outer ring.

[0033] Referring to Figure 2 , a new type of full-needle bearing automatic assembly machine includes a frame 1, on which a rotary feeding device 2 is installed. A feeding device 3 for feeding the outer ring to the rotary feeding device 2, a grease even distribution device 4 for evenly applying grease on the inner wall of the outer ring, a needle loading device 5 for loading needle rollers on the outer ring, a flattening device 6 for pressing the outer ring to make it flat, and a discharging device 7 for discharging the outer ring are also installed on the frame 1.

[0034] First, the feeding device 3 feeds the outer ring to the rotary feeding device 2, and then drives the rotary feeding device 2 to drive the outer ring to reach the grease even distribution device 4, the needle loading device 5, the flattening device 6 and the discharging device 7 in sequence, so that the outer ring can be evenly greased, loaded with needle rollers, pressed and leveled, and discharged in sequence.

[0035] Referring to Figure 3 and Figure 4 , the rotary feeding device 2 includes a hollow rotary platform 21 arranged on the frame 1. A plurality of material holding components 22 are evenly installed on the hollow rotary platform 21 along the circumferential direction. In this embodiment, the number of the material holding components 22 is six. Specifically, the material holding component 22 includes a connecting plate 221 fixedly connected to the hollow rotary platform 21. The connecting plate 221 is provided with a through material receiving groove 2211. The material receiving groove 2211 is arranged vertically. Two installation grooves 2212 are opened on the groove wall of the material receiving groove 2211. The two installation grooves 2212 are arranged oppositely. Each installation groove 2212 is slidably connected with a material pressing member 222. The material pressing member 222 includes an upper inclined portion and a lower inclined portion near the center of the installation groove 2212. The upper inclined portion and the lower inclined portion are used to facilitate the outer ring to be inserted into the material receiving groove 2211 from top to bottom or from bottom to top. One end of the material pressing member 222 near the center of the installation groove 2212 is an arc end 2221. A spring 223 is commonly connected between each material pressing member 222 and the installation groove 2212.

[0036] After the outer ring is inserted into the material receiving groove 2211 from top to bottom or from bottom to top, under the action of the two springs 223, the two material pressing members 222 press the outer ring tightly.

[0037] Referring to Figure 5 , the feeding device 3 includes a connecting frame 31 arranged on the frame 1. A top material cylinder 311 and a material box 32 are installed on the connecting frame 31. The opening of the material box 32 faces one side. The material box 32 can receive the outer ring transferred from the previous process. The top material cylinder 311 is connected with a jacking shaft 33. A through top material hole is opened at the bottom end of the material box 32. The jacking shaft 33 is inserted into the top material hole.

[0038] The outer ring of the previous process flows into the material box 32, and the ejector cylinder 311 works to drive the ejector shaft 33 to move upward, pushing the outer ring into the material receiving groove 2211 and being clamped tightly.

[0039] Refer to Figure 6 , the fat spreading device 4 includes a frame body 41 provided on the frame 1. The frame body 41 is equipped with a receiving and rotating assembly 42, a material transferring assembly 43, and a fat spraying assembly 44. The material transferring assembly 43 is configured to be able to move the outer ring into or out of the receiving and rotating assembly 42. The fat spraying assembly 44 is configured to be able to spray grease onto the inner wall of the outer ring. The receiving and rotating assembly 42 is configured to be able to drive the outer ring to rotate so that the grease is evenly spread on the inner wall of the outer ring.

[0040] Refer to Figure 6 , the receiving and rotating assembly 42 includes a belt rotating part 421 installed on the frame body 41 and a receiving part 422 connected to the belt rotating part 421. The receiving part 422 includes a receiving groove 4221 at the top for placing the outer ring. The belt rotating part 421 is a brushless motor in this embodiment. The material transferring assembly 43 includes a first ejector driving part 431 and a second ejector driving part 432 installed on the frame body 41. Both the first ejector driving part 431 and the second ejector driving part 432 are cylinders. The first ejector driving part 431 is rotatably connected with a pressing shaft 433, and the second ejector driving part 432 is connected with a supporting shaft 434. The pressing shaft 433 and the supporting shaft 434 are respectively located on the upper and lower sides of the receiving groove 4221, and the pressing shaft 433 is located above the supporting shaft 434. The belt rotating part 421 is provided with a receiving hole 4211 penetrating through to the receiving groove 4221. The opening of the receiving hole 4211 is required not to affect the normal operation of the belt rotating part 421, and the supporting shaft 434 is inserted into the receiving hole 4211. The fat spraying assembly 44 needs to be able to spray the grease onto the inner wall of the outer ring. The form of the grease sprayed onto the inner wall of the outer ring is not required. The fat spraying assembly 44 can be composed of, for example, a fat spraying gun and a manipulator connected together. By using the manipulator to drive the fat spraying gun to move, the grease is sprayed onto the inner wall of the outer ring. The specific structure of the fat spraying assembly 44 is the prior art, so it will not be elaborated here.

[0041] Drive the hollow rotary platform 21 to drive the outer ring to move between the pressing shaft 433 and the supporting shaft 434, use the fat spraying assembly 44 to spray the grease onto the inner wall of the outer ring, drive the first ejector driving part 431 and the second ejector driving part 432 to drive the pressing shaft 433 and the supporting shaft 434 to move to respectively abut against the upper and lower ends of the outer ring, and then drive the outer ring to move into the receiving groove 4221. Drive the belt rotating part 421 to drive the receiving part 422 to rotate, thereby driving the outer ring to rotate at a high speed. At this time, the pressing shaft 433 does not separate from the outer ring, and the pressing shaft 433 can prevent the outer ring from flying out when rotating. The outer ring rotating at a high speed will cause the grease to be evenly dispersed on the inner wall of the outer ring.

[0042] It should be noted that in this application, a thick grease such as complex lithium-based grease needs to be selected. It has good viscosity and lubricating ability. After the needle is driven onto the inner wall of the outer ring and comes into contact with such grease by the needle loading device 5, due to the adhesion of the grease, the rolling needles are not easily tilted, and the grease has a certain constraining ability on the positions of the rolling needles.

[0043] Referring to Figure 6 , the thick grease that has been flung and evenly distributed may be distributed between the pressure shaft 433 and the outer ring. The thick grease will cause the outer ring to stick to the pressure shaft 433 and unable to separate. To prevent this situation from occurring, a vertically arranged third ejector driving member 45 is installed on the first ejector driving member 431. The third ejector driving member 45 is a cylinder. The third ejector driving member 45 is connected to a top shaft 46 coaxially arranged with the pressure shaft 433. The pressure shaft 433 is provided with a communication hole 4331 for the top shaft 46 to enter. The third ejector driving member 45 is configured to be able to drive the top shaft 46 to move downward through the communication hole 4331 to push the outer ring away from the pressure shaft 433.

[0044] Referring to Figure 7 and Figure 8 , there are two needle loading devices 5. Taking the structure of one of the needle loading devices 5 as an example: The needle loading device 5 includes a mounting frame 51 provided on the frame 1. A pressing assembly 52 is mounted on the mounting frame 51. The pressing assembly 52 is used to press the outer ring and drive the outer ring to rotate; A needle feeding assembly 53 and a needle driving assembly 54 are also mounted on the mounting frame 51. The needle feeding assembly 53 is used to send the rolling needles into the outer ring, and the needle driving assembly 54 is used to drive the rolling needles onto the inner wall of the outer ring.

[0045] Referring to Figure 7 , the pressing assembly 52 includes a first reciprocating driving member 521 provided on the mounting frame 51. The first reciprocating driving member 521 is a cylinder. The first reciprocating driving member 521 is vertically arranged. The first reciprocating driving member 521 is connected to a first fixing frame 522. A pressing sleeve 523 is rotatably connected to the first fixing frame 522 through a bearing. A secondary pressing sleeve 524 is rotatably connected to the mounting frame 51 below the pressing sleeve 523 through a bearing. The first reciprocating driving member 521 is used to drive the pressing sleeve 523 to move downward to press the outer ring against the secondary pressing sleeve 524.

[0046] Referring to Figure 8 and Figure 9 , the needle feeding assembly 53 includes a loading member 531 mounted on the first fixing frame 522. The loading member 531 is horizontally arranged. The loading member 531 includes a horizontal material feeding channel 5311 inside and a feeding port 5312 at the top communicating with the material feeding channel 5311. Combining Figure 10, a feeding port 5312 is connected to a vibrating disk 532, and a reciprocating driving member II 533 is installed on a loading member 531. The reciprocating driving member II 533 is a cylinder; a vertically arranged reciprocating driving member III 534 is also installed on a mounting frame 51. The reciprocating driving member III 534 is also a cylinder. The reciprocating driving member III 534 is connected to a thimble shaft 535. The thimble shaft 535 is coaxially arranged with an auxiliary pressing sleeve 524. The auxiliary pressing sleeve 524 is provided with a receiving through hole 5241 for the thimble shaft 535 to pass through.

[0047] Refer to Figure 7 and Figure 8 , an injection component 54 includes a reciprocating driving member IV 541 installed on a fixing frame I 522. The reciprocating driving member IV 541 is horizontally arranged. The reciprocating driving member IV 541 is a cylinder. The reciprocating driving member IV 541 is connected to an injection member 542. The injection member 542 includes a pressing portion 5421. The pressing portion 5421 passes through a pressing sleeve 523. The lower end of the pressing portion 5421 is lower than the lower end of the pressing sleeve 523. Therefore, when the pressing sleeve 523 presses the outer ring against the auxiliary pressing sleeve 524, the bottom end of the pressing portion 5421 is located inside the outer ring. And after the needle roller is sent into the outer ring by the needle feeding component 53, the needle roller is located on one side of the pressing portion 5421. At this time, driving the reciprocating driving member IV 541 can drive the injection member 542 to move, thereby driving the pressing portion 5421 to move and pressing the needle roller against the inner wall of the outer ring. In order to be able to fill the inner wall of the outer ring with needle rollers, a rotating member 55 is also installed on the mounting frame 51. The rotating member 55 is a motor. The rotating member 55 is connected to a driving gear 56. The auxiliary pressing sleeve 524 is connected to a driven gear 57. The driving gear 56 meshes with the driven gear 57. The rotating member 55 can drive the auxiliary pressing sleeve 524 to rotate by driving the driving gear 56 and the driven gear 57 to rotate, and then drive the outer ring to rotate to vacate the position for the next needle roller to be loaded on the outer ring.

[0048] The vibrating disk 532 is used to convey the needle rollers into the feeding channel 5311. The reciprocating driving member II 533 is driven to top the needle rollers entering the feeding channel 5311 above the thimble shaft 535. The reciprocating driving member III 534 is driven to drive the thimble shaft 535 to move upward to top the needle rollers into the outer ring. At this time, the needle rollers are located on one side of the pressing portion 5421. The reciprocating driving member IV 541 is driven to drive the injection member 542, that is, the pressing portion 5421, to move and drive the needle rollers into the inner wall of the outer ring. Then the rotating member 55 is driven to drive the outer ring to rotate so that the position for the needle rollers to be loaded is vacated. In cooperation with driving the reciprocating driving member II 533 and the reciprocating driving member III 534 repeatedly according to a certain working rhythm, the inner wall of the outer ring is filled with needle rollers.

[0049] Refer to Figure 11, the flattening device 6 includes a second connecting frame 61 provided on the frame 1. The second connecting frame 61 is installed with a flattening cylinder 62. The flattening cylinder 62 is connected with a vertically arranged flattening shaft 63. A supporting table 64 is also provided on the second connecting frame 61 below the flattening shaft 63. The hollow rotary table 21 can send the outer ring between the flattening shaft 63 and the supporting table 64. At this time, the lower end of the outer ring contacts the supporting table 64, and the flattening cylinder 62 is driven to drive the flattening shaft 63 to move downward to flatten the outer ring so that the multiple needle rollers inside are flat.

[0050] Referring to Figure 12 and Figure 13 and in combination with Figure 1 , the discharging device 7 includes a material channel 71, a discharging assembly 72 and a detection assembly 73. The discharging assembly 72 is used to move the outer ring conveyed by the hollow rotary table 21 into the material channel 71 and make the outer ring flow to the subsequent process. The detection assembly 73 can detect whether the outer ring containing the needle rollers meets the requirements.

[0051] Referring to Figure 12 and Figure 13 , the discharging assembly 72 includes a third connecting frame 721 provided on the frame 1. The third connecting frame 721 is installed with a lifting cylinder 722. The lifting cylinder 722 is connected with a lifting shaft 723. A through receiving port is opened at the bottom end inside the material channel 71. The hollow rotary table 21 can send the outer ring above the lifting shaft 723, and the lifting cylinder 722 is driven to drive the lifting shaft 723 to move upward to push the outer ring through the receiving port into the material channel 71. The material channel 71 is installed with a pushing cylinder 724. The pushing cylinder 724 is located on one side of the receiving port. After the outer ring is pushed into the material channel 71 by the lifting shaft 723, the pushing cylinder 724 works to push the outer ring to flow to the subsequent process.

[0052] Referring to Figure 12 and Figure 13 , the detection assembly 73 includes a positioning cylinder 731, a CCD camera 732 and a rejection cylinder 733 connected to the material channel 71. When the outer ring reaches one side of the positioning cylinder 731, the positioning cylinder 731 works to position the outer ring. The CCD camera 732 takes pictures to detect whether there is a missing needle. The positioning cylinder 731 releases the positioning. If there is no missing needle, the rejection cylinder 733 does not work. If there is a missing needle, the rejection cylinder 733 works to reject this outer ring.

[0053] The implementation principle of a new type of full-needle bearing automatic assembly machine in the embodiment of the present application is as follows: The outer ring from the previous process flows into the material box 32. The top material cylinder 311 works to drive the lifting shaft 33 to move upward to push the outer ring into the material receiving groove 2211 and be clamped tightly by the two material blocking members 222; Drive the hollow rotary platform 21 to drive the outer ring to move between the pressing shaft 433 and the material supporting shaft 434, use the grease spraying assembly 44 to spray grease onto the inner wall of the outer ring, drive the first material ejecting driving part 431 and the second material ejecting driving part 432 to drive the pressing shaft 433 and the material supporting shaft 434 to move to respectively abut against the upper and lower ends of the outer ring and then drive the outer ring to move into the receiving groove 4221, drive the belt rotating part 421 to drive the receiving part 422 to rotate so as to drive the outer ring to rotate at a high speed. At this time, the pressing shaft 433 does not separate from the outer ring, and the pressing shaft 433 can prevent the outer ring from flying out when rotating. The high-speed rotating outer ring will make the grease be evenly dispersed on the inner wall of the outer ring. Then, the pressing shaft 433 and the material supporting shaft 434 move to reset the outer ring with grease attached to the material receiving groove 2211, and then the pressing shaft 433 and the material supporting shaft 434 leave the outer ring; Drive the hollow rotary platform 21 to drive the outer ring to move below the pressure sleeve 523, drive the first reciprocating driving part 521 to drive the pressure sleeve 523 to move downward to press the outer ring on the auxiliary pressure sleeve 524, and the outer ring does not need to separate from the material pressing part 222; Use the vibrating disk 532 to convey the needle rollers into the feeding channel 5311, drive the second reciprocating driving part 533 to push the needle rollers entering the feeding channel 5311 above the ejector pin shaft 535, drive the third reciprocating driving part 534 to drive the ejector pin shaft 535 to move upward to push the needle rollers into the outer ring. At this time, the needle rollers are located on one side of the pressing part 5421, drive the fourth reciprocating driving part 541 to drive the needle injecting part 542, that is, the pressing part 5421, to move to inject the needle rollers into the inner wall of the outer ring. Then drive the rotating part 55 to drive the outer ring to rotate so that the position where the needle rollers are to be loaded is vacated. Under the cooperation of repeatedly driving the second reciprocating driving part 533 and the third reciprocating driving part 534 according to a certain working rhythm, the inner wall of the outer ring is filled with needle rollers, and the pressure sleeve 523 leaves; The hollow rotary platform 21 continues to work to send the outer ring below the flattening shaft 63, drive the flattening cylinder 62 to drive the flattening shaft 63 to move downward to flatten the outer ring so that the multiple needle rollers inside are flat, and the flattening shaft 63 disengages from the outer ring; The hollow rotary platform 21 continues to work to send the outer ring above the lifting shaft 723, drive the lifting cylinder 722 to drive the lifting shaft 723 to move upward to push the outer ring through the material receiving port into the material channel 71, the pushing cylinder 724 works to push the outer ring in the material channel 71 to transfer to the subsequent process. At the same time, the positioning cylinder 731 cooperates with the CCD camera 732 to work and take pictures to detect whether there is a missing needle. If there is no missing needle, the rejecting cylinder 733 does not work. If there is a missing needle, the rejecting cylinder 733 works to reject this outer ring.
