Description

Technical Field

[0001] This utility model belongs to the field of roller bearing manufacturing technology, and in particular relates to a fixed tooling for the production of high-precision roller bearings. Background Technology

[0002] As an important branch of rolling bearings, roller bearings are widely used in modern machinery due to their advantages such as low starting torque, high rotational accuracy and convenient selection. In their production and processing, the fixing fixture plays a key role, especially when fixing the rollers, the performance of the fixture directly affects the processing quality.

[0003] Currently, existing roller bearing fixing fixtures struggle to apply a balanced clamping force to the roller bearings when clamping and fixing them. Uneven clamping forces cause uneven stress on the rollers during processing, which can easily lead to positional misalignment. This not only makes it difficult to guarantee the dimensional accuracy of the rollers, but also causes localized wear to intensify during subsequent assembly and use due to uneven stress, significantly reducing the service life and overall performance of the roller bearings, increasing the product defect rate, raising production costs, and seriously affecting production efficiency and corporate economic benefits. Utility Model Content

[0004] The purpose of this invention is to provide a fixture for the production of high-precision roller bearings. By setting up a clamping mechanism, specifically, the inner ring of the bearing cooperates with the positioning pin to achieve initial positioning, laying the foundation for subsequent clamping. Once the motor starts, it drives the rotating shaft to rotate, which in turn drives the turntable to rotate synchronously. Because the four arc-shaped grooves on the turntable are slidably connected to the transmission rod at the bottom of the limiting rod, when the turntable rotates, the arc-shaped trajectory of the grooves generates a lateral thrust on the transmission rod, forcing the transmission rod to drive the limiting rod to slide. The limiting rod then drives the connecting plate and clamping blocks to synchronously approach the bearing, achieving clamping. The four V-shaped clamping blocks are evenly distributed, applying balanced clamping force from multiple directions, preventing bearing displacement or deformation, ensuring stable position during processing, guaranteeing processing accuracy, and meeting the requirements of high-precision production. This solves the problem of existing roller bearing fixtures being unable to apply a balanced clamping force to the roller bearing during clamping and fixing.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a fixed fixture for the production of high-precision roller bearings, including a fixture table, and further comprising:

[0007] A clamping mechanism, mounted on a tooling table, is used to clamp and fix the bearing. The clamping mechanism includes a placement platform slidably connected to the top of the tooling table, and a positioning post fixedly connected to the top of the placement platform; and

[0008] A rotating assembly is mounted on a tooling table. The rotating assembly is used to drive the bearing to rotate through a clamping mechanism. The rotating assembly includes a connecting sleeve fixedly connected to the bottom of the placement table. The bottom end of the connecting sleeve passes through the top of the tooling table and is rotatably connected to the top of the tooling table.

[0009] The outer wall of the connecting sleeve is fixedly connected with a boss, and the inner circular wall of the top of the tooling table is provided with a groove. The side of the boss on the outer wall of the connecting sleeve away from the connecting sleeve extends into the groove and slides into the groove.

[0012] A drive assembly 1 is mounted on a tooling table and is used to provide power for the clamping assembly to clamp and fix the bearing.

[0013] A transmission component 1 is disposed inside the placement platform and is used to convert the rotational motion of the drive component 1 into the linear motion of the clamping component.

[0014] Although the transmission component converts the rotational motion of the drive component into the linear motion of the clamping component, the clamping component needs to be moved in cooperation with the limiting component.

[0015] Furthermore, the rotating assembly also includes a second driving assembly, which is mounted on the tooling table and provides power for rotating the bearing via the clamping mechanism; and

[0016] The second transmission component is mounted on the tooling table and is used to convert the rotational motion of the second drive component into the rotational motion of the clamping mechanism.

[0017] Furthermore, the clamping assembly includes four connecting plates slidably connected to the top of the placement platform, and clamping blocks are fixedly connected to the side of each of the four connecting plates near the center of the placement platform, and anti-slip pads are fixedly connected to the inner walls of each of the four clamping blocks.

[0018] All four clamping blocks are designed in a V-shape, with their openings facing the center of the placement platform.

[0019] Furthermore, the limiting component includes a disc fixedly connected to the inner wall of the placement platform, with four limiting rods passing through the disc. All four limiting rods are slidably connected to the disc, and the side of each of the four limiting rods away from the center of the disc extends to the outside of the placement platform and is slidably connected to the placement platform. The side of each of the four limiting rods away from the center of the disc is fixedly connected to a corresponding connecting plate.

[0020] The four limit rods are all designed in a cross shape, and the side of each limit rod away from the center of the disc is fixedly connected to the corresponding connecting plate by welding.

[0021] Furthermore, the drive assembly includes a motor installed at the bottom of the placement platform. The output shaft of the motor is fixedly connected to a rotating shaft via a coupling. The top end of the rotating shaft extends into the interior of the placement platform and is rotatably connected to the placement platform.

[0022] The motor is bolted to the bottom of the placement platform and is located inside the connecting sleeve.

[0023] Furthermore, the transmission assembly includes a turntable fixedly connected to the top of the rotating shaft. The turntable has four sliding grooves. The bottom of each of the four limiting rods is fixedly connected to a transmission rod. The bottom ends of the four transmission rods pass through the turntable and are slidably connected to the corresponding sliding grooves.

[0024] All four slides are designed to be arc-shaped, and all four transmission rods are adapted to the corresponding slides.

[0025] Furthermore, the second drive assembly includes a second motor mounted on a tooling table, and the output shaft of the second motor is fixedly connected to a second rotating shaft via a coupling.

[0026] Furthermore, the transmission assembly two includes a gear ring fixedly connected to the outer wall of the connecting sleeve, and a gear is fixedly connected to the top end of the rotating shaft two, with the gear ring and the gear being adapted to each other;

[0027] The gear is fixedly connected to the second rotating shaft by welding.

[0028] This utility model has the following beneficial effects:

[0029] 1. This utility model uses a clamping mechanism, specifically, where the inner ring of the bearing cooperates with the positioning post to achieve initial positioning, laying the foundation for subsequent clamping. Once the motor starts, it drives the rotating shaft to rotate, which in turn drives the turntable to rotate synchronously. Since the four arc-shaped grooves on the turntable are slidably connected to the transmission rod at the bottom of the limiting rod, when the turntable rotates, the arc-shaped trajectory of the grooves will generate a lateral thrust on the transmission rod, forcing the transmission rod to drive the limiting rod to slide. The limiting rod then drives the connecting plate and clamping blocks to move closer to the bearing synchronously, achieving clamping. The four V-shaped clamping blocks are evenly distributed, which can apply balanced clamping force from multiple directions, preventing bearing displacement or deformation, ensuring stable position during processing, guaranteeing processing accuracy, and meeting the requirements of high-precision production.

[0030] 2. This utility model, by setting up a rotating component, specifically by using a second motor to drive a second rotating shaft and a gear to rotate, and by the meshing of the gear and the gear ring, transmits power to the connecting sleeve, causing the connecting sleeve to rotate together with the placement table, the clamping mechanism, and the clamped bearing. This allows the bearing to achieve continuous circumferential position changes during processing, enabling the tool to continuously process the circumferential surface of the bearing without stopping to adjust the bearing angle midway, ensuring the continuity of the processing, reducing processing marks caused by interruptions, and thus improving the processing accuracy and surface quality of the bearing's circumferential surface.

[0031] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0042] Please see Figure 1-6 As shown, this utility model is a fixed tooling for the production of high-precision roller bearings, including a tooling table 1, and further comprising:

[0043] Clamping mechanism 2, mounted on tooling table 1, is used to clamp and fix the bearing. Clamping mechanism 2 includes a placement platform 21 slidably connected to the top of tooling table 1, with a positioning post 211 fixedly connected to the top of the placement platform 21; and

[0044] Rotating assembly 3 is mounted on tooling table 1. Rotating assembly 3 is used to drive the bearing to rotate through clamping mechanism 2. Rotating assembly 3 includes connecting sleeve 31 fixedly connected to the bottom of placement table 21. The bottom end of connecting sleeve 31 passes through the top of tooling table 1 and is rotatably connected to the top of tooling table 1. A boss is fixedly connected to the outer wall of connecting sleeve 31. A groove is opened on the inner circular wall surface of the top of tooling table 1. The side of the boss on the outer wall of connecting sleeve 31 away from connecting sleeve 31 extends into the groove and is slidably connected to the groove.

[0045] The clamping mechanism 2 also includes a clamping assembly 22, which is disposed on the top of the placement platform 21 and is used to clamp and fix the bearing; and

[0047] Drive assembly 24 is mounted on tooling table 1 and is used to provide power for clamping assembly 22 to clamp and fix the bearing.

[0048] Transmission component 25 is disposed inside the placement platform 21. Transmission component 25 is used to convert the rotational motion of drive component 24 into the linear motion of clamping component 22. Although transmission component 25 converts the rotational motion of drive component 24 into the linear motion of clamping component 22, the clamping component 22 is moved by the cooperation of limiting component 23.

[0049] The rotating assembly 3 also includes a second drive assembly 32, which is mounted on the tooling table 1. The second drive assembly 32 provides power for rotating the bearing via the clamping mechanism 2; and

[0050] Transmission component 2 33 is mounted on the tooling table 1. Transmission component 2 33 is used to convert the rotational motion of drive component 2 32 into the rotational motion of clamping mechanism 2.

[0051] The clamping assembly 22 includes four connecting plates 221 slidably connected to the top of the placement platform 21. Each of the four connecting plates 221 has a clamping block 222 fixedly connected to one side near the center of the placement platform 21. Each of the four clamping blocks 222 has an anti-slip pad 223 fixedly connected to its inner wall. The four anti-slip pads 223 are made of polyurethane composite material and have protrusions on their surfaces to increase the coefficient of friction with the outer wall of the bearing.

[0052] The limiting component 23 includes a disc 231 fixedly connected to the inner wall of the placement platform 21. Four limiting rods 232 pass through the disc 231. All four limiting rods 232 are slidably connected to the disc 231. The side of each of the four limiting rods 232 away from the center of the disc 231 extends to the outside of the placement platform 21 and is slidably connected to the placement platform 21. The side of each of the four limiting rods 232 away from the center of the disc 231 is fixedly connected to the corresponding connecting plate 221. The four limiting rods 232 are evenly distributed on the disc 231 and limit the four connecting plates 221 through sliding cooperation with the disc 231.

[0053] The drive assembly 24 includes a motor 241 mounted on the bottom of the placement platform 21. The output shaft of the motor 241 is fixedly connected to a rotating shaft 242 via a coupling. The top end of the rotating shaft 242 extends into the interior of the placement platform 21 and is rotatably connected to the placement platform 21. The rotating shaft 242 is rotatably connected to the bottom of the placement platform 21 via a bearing.

[0054] The transmission assembly 25 includes a turntable 251 fixedly connected to the top of the rotating shaft 242. The turntable 251 has four sliding grooves 252. The bottom of each of the four limiting rods 232 is fixedly connected to a transmission rod 253. The bottom ends of the four transmission rods 253 pass through the turntable 251 and are slidably connected to the corresponding sliding grooves 252. The four transmission rods 253 are fixedly connected to the corresponding limiting rods 232 by welding.

[0055] The drive assembly 2 32 includes a motor 2 321 mounted on the tooling table 1, and the output shaft of the motor 2 321 is fixedly connected to a rotating shaft 2 322 via a coupling.

[0056] The transmission assembly 33 includes a gear ring 331 fixedly connected to the outer wall of the connecting sleeve 31, and a gear 332 fixedly connected to the top of the rotating shaft 322. The gear ring 331 and the gear 332 are adapted to each other. After the motor 321 is started, it drives the gear 332 to rotate through the rotating shaft 322. When the gear 332 rotates, it drives the connecting sleeve 31 to rotate through meshing with the gear ring 331. In turn, the connecting sleeve 31 drives the placement platform 21 and the clamping mechanism 2 on the placement platform 21 to rotate.

[0057] A specific application of this embodiment is as follows: When it is necessary to clamp and fix the bearing, first place the bearing on the top of the placement platform 21, so that the inner ring of the bearing cooperates with the positioning post 211 on the top of the placement platform 21. The positioning post 211 achieves the initial positioning of the bearing. Then, the motor 241 starts and drives the rotating shaft 242 to rotate. The rotation of the rotating shaft 242 drives the turntable 251 to rotate together. Since the turntable 251 has four arc-shaped sliding grooves 252, and the bottom ends of the transmission rods 253 fixedly connected to the bottom of the four limiting rods 232 pass through the turntable 251 and slide in connection with the corresponding sliding grooves 252, when the turntable 251 rotates, the four sliding grooves 252 engage with the corresponding transmission rods 253. 53 generates a force that causes the four transmission rods 253 to slide along the corresponding limit rods 232 along the disc 231. At the same time, the four limit rods 232 drive the connecting plate 221 fixedly connected to them to slide on the top of the placement platform 21, causing the four connecting plates 221 to move, which in turn drives the four clamping blocks 222 to move synchronously until the anti-slip pad 223 on the inner wall of the clamping block 222 makes tight contact with the outer wall of the bearing, thus completing the stable clamping of the bearing. The anti-slip pad 223, with its own polyurethane composite material properties and surface protrusion structure, increases the coefficient of friction with the outer wall of the bearing, avoiding damage to the bearing surface. At the same time, it adapts to the slight fluctuations in the bearing size, ensuring the reliability of clamping.

[0058] When the clamped bearing needs to be rotated, the motor 321 in the drive assembly 32 starts, and its output shaft drives the rotating shaft 322 to rotate through the coupling. The rotation of the rotating shaft 322 drives the gear 332 in the transmission assembly 33 to rotate together. Since the gear 332 meshes with the gear ring 331 fixedly connected to the outer wall of the connecting sleeve 31, the rotation of the gear 332 drives the gear ring 331 and the connecting sleeve 31 to rotate together. The bottom end of the connecting sleeve 31 is rotatably connected to the top of the tooling table 1, and the boss on its outer wall slides in the groove on the inner circular wall of the top of the tooling table 1, ensuring the stability of the rotation of the connecting sleeve 31. The rotation of the connecting sleeve 31 drives the placement table 21 and the clamping mechanism 2 on the placement table 21 to rotate synchronously, thereby driving the clamped bearing to rotate through the clamping mechanism 2, which meets the needs of processing different positions during the bearing processing.
