Description

Technical Field

[0001] The utility model relates to the technical field of needle roller bearing processing equipment, in particular to a rotary assembly equipment for needle roller bearing processing. Background Art

[0002] Needle roller bearings are roller bearings with cylindrical rollers, where the rollers are thin and long, called needle rollers. Despite the small cross-section of the needle rollers, the bearings still have a high load-bearing capacity. Needle roller bearings are equipped with thin and long rollers, so the radial structure is compact. When the inner diameter size and load capacity of the bearing are the same as other types of bearings, the needle roller bearing has the smallest outer diameter, which is particularly suitable for support structures with limited radial installation dimensions. Existing assembly equipment usually needs to position the bearing when processing and assembling it.

[0003] At present, the positioning parts of the existing assembly equipment are mostly simple in structure. The diameters of the needle roller bearings vary according to the different application scenarios. The existing grinding mechanisms are usually inconvenient to adjust, which makes it impossible to adapt to bearings of different diameters. It may be necessary for personnel to manually operate the assembly process or use different types of assembly equipment to adapt and position bearings of different diameters, which increases the cost of use and reduces the practicality of the equipment. Therefore, we propose a rotary assembly equipment for needle roller bearing processing to solve the above problems. Utility Model Content

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] Furthermore, the transmission assembly includes a bidirectional screw rod 10 arranged in the installation groove, both ends of the bidirectional screw rod 10 are rotatably connected to the adjacent inner walls in the installation groove, and both ends of the outside of the bidirectional screw rod 10 are sleeved with screw sleeves 11. Specifically, through the setting of the installation groove, the installation groove can facilitate the placement and installation of the bidirectional screw rod 10 and the two screw rods 9 and the screw sleeves 11 and the nuts 12, reducing the occupied space on the top of the base plate 1 and providing a protective effect through the base plate 1, avoiding the situation where personnel accidentally touch the bidirectional screw rod 10 and the screw rod 9 and get injured when the equipment is running, and also keeping the equipment operating platform clean.

[0026] Furthermore, the transmission assembly also includes two screw rods 9 symmetrically arranged in the installation groove, one end of one of the screw rods 9 passes through the side wall of the bottom plate 1 and extends to the outside through a shaft sleeve, and a motor 6 is fixedly installed on one side of the outside of the bottom plate 1 through a bracket, and the output end of the motor 6 is transmission-connected with one end of an adjacent screw rod 9 extending to the outside of the bottom plate 1, and the other end of the screw 9 away from the motor 6 is rotationally connected with the adjacent inner wall in the installation groove, and nuts 12 are sleeved on the outside of the two screw rods 9. Specifically, through the setting of the motor 6, one of the screw rods 9 is driven to rotate by starting the motor 6, and the main bevel gear 14 is rotated through one of the secondary bevel gears 15. At the same time, another secondary bevel gear 15 is driven to rotate through the latch teeth, so that the two screws 9 and the bidirectional screw 10 rotate at the same time, and the two adjacent screw sleeves 11 and the two nuts 12 are driven to move. At the same time, multiple limit plates 13 and multiple short rods 8 are used to drive multiple clamping plates 7 to move toward the middle position of the base plate 1, and then the bearings placed on the top of the rotating table 5 are processed and assembled. After completion, the multiple clamping plates 7 can be separated from each other by reversing the motor 6 to release the clamping positioning of the outside of the bearing, which is convenient for subsequent assembly operations, thereby achieving a certain degree of adaptation to bearings of different diameters and sizes and processing and assembly, reducing processing costs and improving the practicality of the equipment.

[0027] Furthermore, the transmission assembly also includes a main bevel gear 14 arranged in the mounting groove, the interior of the main bevel gear 14 is socketed with the outer middle part of the bidirectional screw rod 10, and both sides of the main bevel gear 14 are connected to the auxiliary bevel gear 15 through the meshing of the latch teeth, and the ends of the two auxiliary bevel gears 15 that are away from each other are fixedly connected to the ends of the two screw rods 9 that are close to each other. Specifically, through the arrangement of the main bevel gear 14 and the auxiliary bevel gear 15, when the motor 6 drives one of the screw rods 9 to rotate, it also drives one of the auxiliary bevel gears 15 to rotate and causes the main bevel gear 14 to rotate through the latch teeth, and at the same time drives the other auxiliary bevel gear 15 to rotate through the latch teeth, so that the driving source of a single motor 6 can simultaneously drive the two screw rods 9 and the bidirectional screw rod 10 to rotate, so that multiple clamping plates 7 are displaced, thereby achieving the effect of saving resources, without the need for personnel to use multiple driving sources to drive, and reducing processing costs.

[0028] Furthermore, the transmission assembly also includes a limit plate 13 arranged on the top of the two screw sleeves 11 and the two nuts 12, the bottoms of the multiple limit plates 13 are fixedly connected to the tops of the adjacent screw sleeves 11 and nuts 12, and the exteriors of the multiple limit plates 13 are adapted to the mounting grooves, and the tops of the multiple limit plates 13 are fixedly installed with the bottoms of the multiple clamping plates 7 through the short rods 8. Specifically, through the setting of the limit plate 13, the limit plate 13 can provide a stable supporting force for the clamping plate 7 while cooperating with the limit groove to limit the nut 12 and the screw sleeve 11, so that the clamping plate 7 can be driven by the screw sleeve 11 and the nut 12 to move to achieve the effect of adapting to bearings of different sizes.

[0029] Furthermore, there are four supporting legs, the tops of the four supporting legs are all in a circular array and fixedly connected to the bottom of the base plate 1, and the inner arc surfaces of the multiple clamping plates 7 are provided with anti-slip grooves. Specifically, through the arrangement of multiple supporting legs, the multiple supporting legs can provide a stable supporting force for the equipment as a whole, making the equipment more stable during operation. Through the arrangement of anti-slip grooves, the anti-slip grooves can increase the friction of the clamping plate 7, making the clamping plate 7 more stable when clamping the outside of the bearing.

[0030] In summary:

[0031] By starting the motor 6, one of the screw rods 9 is driven to rotate and the main bevel gear 14 is rotated through one of the secondary bevel gears 15, and the other secondary bevel gear 15 is driven to rotate through the latch teeth, so that the two screw rods 9 and the bidirectional lead screw 10 are rotated at the same time, and the two adjacent screw sleeves 11 and the two nuts 12 are driven to be displaced. At the same time, multiple limit plates 13 and multiple short rods 8 are used to drive multiple clamping plates 7 to move toward the middle position of the base plate 1, and then the bearing placed on the top of the rotating table 5 is processed and assembled. After completion, the multiple clamping plates 7 can be separated from each other by reversing the motor 6 to release the clamping positioning of the outside of the bearing, which is convenient for subsequent assembly operations, thereby achieving a certain degree of adaptation to bearings of different diameters and processing and assembly, reducing processing costs and improving the practicality of the equipment.
