Description

Technical Field

[0001] The invention relates to the technical field of bearing processing, in particular to an automatic arrangement and assembly device for needle rollers. Background Art

[0002] The assembly of rolling bearings in reducers is a delicate and critical process, which directly affects the operating efficiency and life of the reducer. Among them, needle rollers, as a special rolling element of rolling bearings, play a key role in specific types of rolling bearings (such as needle roller bearings).

[0003] Needle rollers refer to the rotating body on needle roller bearings, which are mainly used in various types of bearings, especially roller bearings with cylindrical rollers. Needle rollers are slender in shape, like needles. This type of bearing has a high load bearing capacity and a compact radial structure. It is suitable for occasions with high speed, large load and small bearing space. Needle rollers are widely used in machinery, including automobiles, aerospace, robots, electronic equipment and other fields.

[0004] During the assembly process, the mounting surfaces of the reducer and needle bearing should be thoroughly cleaned to ensure that there is no dirt residue. At the same time, check whether the model, surface quality and radial clearance of the needle bearing meet the requirements, and ensure that the needle bearing is fully lubricated to reduce friction and wear. However, most of the existing assembly is done manually by operators, resulting in low production efficiency. During the installation process, the assembly method is prone to defects such as low assembly efficiency, grease pollution, high labor intensity of workers, poor assembly accuracy, and high rework rate. For this reason, we propose an automatic arrangement assembly device for needle rollers to solve the above problems. Summary of the invention

[0027] 4. The present invention moves through the transmission belt, and the connecting rod can rotate under the action of the transmission belt, so that the arc-shaped pressure plate and the surface of the docking plate are squeezed, so that the internal air pressure of the expansion ball changes continuously, and the needle roller can be pushed to move inside the semi-cylindrical groove.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figure 1-Figure 7 The present invention provides a technical solution: an automatic arrangement and assembly device for needle rollers, comprising:

[0039] A processing table 1, a fixing frame 11 is installed at the bottom of the processing table 1;

[0040] The storage and feeding mechanism 2 is arranged at both ends of the processing table 1. The storage and feeding mechanism 2 is used for storing and feeding the needle rollers. The storage and feeding mechanism 2 can clean the debris and impurities remaining between the needle rollers during the feeding process;

[0041] Auxiliary transport mechanism 3, the auxiliary transport mechanism 3 is installed on the top of the processing table 1, and the auxiliary transport mechanism 3 is arranged between the storage and feeding mechanisms 2 on both sides;

[0042] The position limiting storage mechanism 4 is installed on the auxiliary transport mechanism 3. The position limiting storage mechanism 4 can arrange and stack the needle rollers neatly, which can improve the installation efficiency. When the needle rollers need to be arranged and sorted, they can be dumped into the storage and feeding mechanism 2, and the auxiliary transport mechanism 3 can drive the position limiting storage mechanism 4 to move so that it is tilted and inserted in the separation chamber 23. As the needle rollers are quickly dumped on the top of the fixed tray 41, the needle rollers can be stuck on the top of the docking plate 42, which can play a role in rapid screening and limiting, and is convenient for subsequent picking and assembly.

[0043] like Figure 2As shown, the storage and feeding mechanism 2 includes a positioning seat 21, a lifting arm 22 and a separation chamber 23. The positioning seat 21 is installed at both ends of the top of the processing table 1. A plurality of transmission grooves are opened on the positioning seat 21. The lifting arm 22 is movably connected inside the transmission groove. The separation chamber 23 is installed on the top of the lifting arm 22. The separation chamber 23 is used to store the needle rollers. As the lifting arm 22 drives the top separation chamber 23 to tilt, the internal needle rollers can be moved to facilitate subsequent feeding, and at the same time can play a role in auxiliary screening.

[0044] like Figure 4 As shown, in order to reduce the mixing of metal debris in the needle roller or the mixing of foreign debris into the separation chamber 23 during the processing, a plurality of reset plates 28 are installed at the bottom of the separation chamber 23. The reset plates 28 are arranged in a uniform array at the bottom of the separation chamber 23. A plurality of circular grooves are formed on the reset plates 28, and a pneumatic insert rod 281 is inserted in the circular groove. An extrusion ring is installed on the side wall of the pneumatic insert rod 281.

[0045] A card tube 29 is provided between the reset pressure plate 28. The top of the card tube 29 is made of a grid material. A plurality of staggered rubber rods are provided inside the card tube 29. The side wall of the card tube 29 is in contact with the extrusion ring. As the roller needle inside the separation chamber 23 moves, debris and impurities in the gap can be shaken off into the card tube 29. The air pressure insert rod 281 can be squeezed during the movement of the roller needle, which can drive the extrusion ring and the card tube 29 to be squeezed, thereby deforming the card tube 29 to prevent debris and impurities from accumulating in the grid at the top. At the same time, the rubber rod can move by friction to collect and process the debris and impurities, which is convenient for subsequent disassembly, cleaning and maintenance, and reduces the occurrence of defective products caused by impurities during assembly.

[0046] like Figure 3 As shown, in order to cooperate with the limiting storage mechanism 4 to perform feeding processing and reduce the time wasted in picking and screening, the storage feeding mechanism 2 also includes a tilting bucket 24 and a feeding hopper 25. Both sides of the separation chamber 23 are provided with mounting grooves, and the tilting bucket 24 and the feeding hopper 25 are installed inside the mounting grooves. An elastic plate is installed on the inner wall of the tilting bucket 24;

[0047] A plurality of blocking plates 26 are movably provided on one side of the upper hopper 25. The blocking plates 26 are elastic and are fixedly connected to a positioning frame 27 made of metal. A buffer shaft 261 is inserted inside the blocking plates 26. The buffer shaft 261 is hollow inside and can be used in conjunction with the blocking plates 26 to assist in loading. As the separation chamber 23 can be tilted, the roller needles and the like are moved to the inside of the upper hopper 25, and the roller needles are limited and blocked under the action of the blocking plates 26. The blocking plates 26 can be deformed under the action of gravity, so that the internal buffer shaft 261 can be squeezed and flattened, thereby preventing the roller needles at the bottom from being stuck inside the blocking plates 26.

[0048] like Figure 5 As shown, in order to improve the efficiency of screening, the auxiliary transfer mechanism 3 includes a fixed table 31, which is installed at the middle end of the top of the processing table 1. A movable plate 32 is movably provided on the top of the fixed table 31. A pair of transmission shafts 33 are movably clamped on the top of the movable plate 32. A hinge frame 34 is movably installed on the top of the transmission shaft 33. A limiting storage mechanism 4 is arranged on one side of the hinge frame 34, which can drive the fixed tray 41 to move inside the separation chamber 23, and can make the needle rollers circulate and roll inside the fixed tray 41, and can evenly clamp the needle rollers on the surface of the docking plate 42, which can effectively improve the overall assembly efficiency.

[0049] like Figure 5 and Figure 7 As shown, in order to reduce the overflow of the needle roller during the limiting process of loading, the limiting storage mechanism 4 includes a fixed tray 41 and a group of docking plates 42. The fixed tray 41 is arranged on one side of the auxiliary transport mechanism 3 and can move with the auxiliary transport mechanism 3. A rectangular groove is opened on the fixed tray 41, and the docking plates 42 are installed at both ends of the rectangular groove. A plurality of semi-cylindrical grooves are provided on the docking plate 42 for limiting the storage of the needle roller;

[0050] A buffer baffle 48 is installed at one end of the fixed tray 41. The buffer baffle 48 is set at an angle. A plurality of friction plates 481 are installed on the buffer baffle 48. The friction plates 481 are "U"-shaped. The buffer baffle 48 can play a blocking role to prevent the roller needle from passing over the top of the fixed tray 41 and escaping from the separation chamber 23 during the loading process of the fixed tray 41, thereby reducing losses during the processing process.

[0051] like Figure 6 As shown, in order to evenly lubricate the surface of the needle roller, a pair of limit plates 411 are installed on the surface of the fixed tray 41. The limit plates 411 are arc-shaped and are located between the docking plates 42. A transmission belt 44 is movably clamped between the limit plates 411. A through groove is opened at the bottom of the fixed tray 41. The position of the transmission belt 44 corresponds to the through groove. A connecting rod 46 is movably clamped on one side of the docking plate 42 close to the transmission belt 44. A movable roller 45 is installed between the connecting rods 46. The movable roller 45 moves with the transmission belt 44.

[0052] A cavity is provided inside the connecting rod 46, and an expansion ball 462 is provided inside the cavity. A plurality of arc-shaped pressure plates 461 are installed on the outer wall of the expansion ball 462. One side of the arc-shaped pressure plate 461 passes through the cavity. The arc-shaped pressure plate 461 is squeezed against the surface of the docking plate 42 during the rotation of the connecting rod 46. The transmission belt 44 can rub against the elastic plate, and can drive the movable roller 45 and the connecting rod 46 to move. During the rotation of the connecting rod 46, the arc-shaped pressure plate 461 can be squeezed and rubbed against the inside of the semi-cylindrical groove, and the expansion ball 462 can be deformed, so that the needle roller moves, collides with one side of the buffer ring 471, can be reset under the reaction force, and can push the needle roller to reciprocate in the semi-cylindrical groove. In cooperation with the transmission plate 43, the lubricating oil can be evenly applied to the surface of the needle roller, and during the reciprocating motion, the needle roller itself can rotate under the action of the lubricating oil, and its surface can be evenly lubricated to reduce omissions.

[0053] In order to reduce the adhesion of impurities during the subsequent installation process, a plurality of transmission plates 43 are installed on the docking plate 42. The transmission plates 43 are made of sponge material. An oil storage pipe is installed inside the fixed tray 41. The oil storage tray is clamped inside the rectangular groove and located directly below the docking plate 42. The transmission plates 43 are clamped inside the oil storage pipe.

[0054] An adjusting rod 47 is movably provided on the side of the docking plate 42 away from the transmission belt 44, one end of the adjusting rod 47 is installed with a compression spring, and the other end of the compression spring is installed with a buffer ring 471. The buffer ring 471 can limit the needle roller. A straight groove is provided on the adjusting rod 47 to facilitate the removal of the adjusting rod 47 from the docking plate 42. Under the action of the movable plate 32, the needle roller can be driven to move, so that the needle roller on one side is stuck in the buffer ring 471 under the action of inertia, which plays a role of auxiliary limiting. The operator can directly take the adjusting rod 47 without grabbing it from the semi-cylindrical groove, which prevents impurities from remaining in the semi-cylindrical groove and ensures the processing quality of the equipment.

[0055] Working principle: first, when the needle rollers need to be arranged and sorted, they can be dumped into the storage and feeding mechanism 2, and the auxiliary transport mechanism 3 can drive the limit storage mechanism 4 to move, so that it is tilted and inserted into the separation chamber 23. As the needle rollers are quickly dumped on the top of the fixed tray 41, the needle rollers can be clamped on the top of the docking plate 42, which can play a role in rapid screening and limiting. As the needle rollers are dumped into the separation chamber 23, the separation chamber 23 can be tilted toward one side of the upper hopper 25 under the action of the lifting arm 22, so that the needle rollers can all move to the upper hopper 25. At the same time, the blocking insert plate 26 can be against one side thereof to play a blocking role, so that the needle rollers can be evenly dumped on the top of the limit storage mechanism 4 in the future. As the needle rollers move, they can deform with the air pressure insert rod 281, which can push the edge of the clamping tube 29 to deform, and can collect and absorb metal debris and impurities, which is convenient for subsequent unified processing, and reduces the mixing of impurities between the needle rollers during the processing process, which affects the subsequent assembly quality.

[0056] Then, under the action of the movable plate 32 and the hinged frame 34, the fixed tray 41 can be inserted obliquely on one side of the separation chamber 23, and as the blocking plug plate 26 is reset, the needle rollers can be pushed to the surface of the fixed tray 41, so that the needle rollers can be stuck in the semi-cylindrical groove on the surface of the docking plate 42, which plays a collecting role and is convenient for subsequent picking and assembly. After the collection is completed, the fixed tray 41 can be moved, so that the transmission belt 44 and the elastic plate on the top of the tilting bucket 24 can rub, so that the transmission belt 44 can be moved, and the connecting rod 46 can be rotated under the action of the transmission belt 44, so that the arc pressure plate 461 and the surface of the docking plate 42 are squeezed, so that the internal air pressure of the expansion ball 462 changes continuously, which can push the needle roller to move inside the semi-cylindrical groove, and the surface of the needle roller can be lubricated with oil by means of the transmission plate 43, and there is no need to lubricate separately during the subsequent installation process. During the movement of the needle roller, it can collide with the buffer ring 471, and can be pushed to rotate inside the semi-cylindrical groove under the action of the buffer spring, so that its surface can be evenly lubricated with oil.

[0057] Finally, when installation is required, as the movable plate 32 moves to one side, the needle roller on one side can be stuck in the buffer ring 471 under the action of inertia, and the operator can directly take out the adjusting rod 47 from the semi-cylindrical groove, which can reduce the contact with the needle roller during the subsequent assembly process and avoid impurities adhering to its surface, thereby ensuring the processing quality of the equipment and reducing the occurrence of defective products.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
