Description

Technical Field

[0001] This utility model relates to the field of testing technology, and in particular to a positioning bracket for measuring the dimensions of gearbox bearings. Background Technology

[0002] Gearbox bearings are core components installed inside the gearbox. Their main function is to support key components such as gear shafts in the gearbox, while reducing the frictional resistance of these components during operation. They need to directly bear the forces generated during gear transmission, such as radial force, axial force, or a combination of both, and also adapt to the high-speed rotation, vibration, and specific temperature environment during gearbox operation.

[0003] In existing technologies, bearings are typically fixed by external clamping to prevent displacement during testing. The clamping components of the external clamping device usually cover part of the outer ring surface of the bearing. These areas may be the measurement points that the testing tool needs to contact. The presence of the clamping components will occupy the testing space, making it difficult for the testing tool to reach the target position smoothly, or requiring it to detour and adjust the angle. This not only increases the difficulty of operation, but may also introduce measurement errors due to angle deviation, which may lead to errors in the test data. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a gearbox bearing size detection and positioning bracket.

[0005] This utility model is achieved by the following technical solution: a gearbox bearing size detection and positioning bracket, including a detection table, a positioning component is provided inside the detection table, and a rotating component is provided on the outer wall of the detection table; The positioning component includes a guide groove, which is formed inside the detection table. The outer wall of the detection table has a T-shaped sliding groove, and the inner wall of the detection table has a rotating groove. A rotating ring is rotatably connected to the outer wall of the rotating groove, and a rotating column is fixedly connected to the inner wall of the rotating ring. A motor is fixedly connected to the bottom of the rotating column. An arc-shaped guide groove is formed at the end of the rotating column away from the motor. A sliding rod is slidably connected to the outer wall of the arc-shaped guide groove. A clamping block is fixedly connected to the top of the sliding rod, and a T-shaped slider is fixedly connected to the bottom of the clamping block.

[0006] As a further improvement to the above solution, the motor is fixedly connected to the inner wall of the testing platform, the sliding rod is slidably connected to the outer wall of the guide groove, and the T-shaped slider is slidably connected to the outer wall of the T-shaped slide groove.

[0007] Through the above technical solution, the clamping block fixed at the top of the sliding rod drives the T-shaped slider at the bottom to slide synchronously in the T-shaped groove. The double guide structure ensures that the clamping block moves smoothly. The three clamping blocks move under the drive of the sliding rod until they fit against the inner wall of the bearing, realizing the internal support fixation of the bearing. The internal support fixation avoids the outer ring detection surface of the bearing, completely eliminating obstruction and ensuring that the detection equipment can directly collect the full surface data of the outer ring, improving detection accuracy and reducing detection error.

[0008] As a further improvement to the above solution, the rotating assembly includes a support frame, and a connecting rod is rotatably connected inside the support frame. The connecting rod is fixedly connected to the outer wall of the testing platform.

[0009] As a further improvement to the above solution, two support frames are provided, which are symmetrically arranged around the testing platform. Two connecting rods are also provided, which are symmetrically arranged around the testing platform.

[0010] With the above technical solution, the connecting rod rotates inside the support frame while being fixed to the testing table. The support frame supports the testing table through the connecting rod, ensuring the stable rotation of the testing table.

[0011] As a further improvement to the above solution, a worm gear is fixedly connected to the outer wall of the connecting rod, and the worm gear is meshed with a worm.

[0012] As a further improvement to the above solution, a fixing block is rotatably connected to the outer wall of the worm gear, and the fixing block is fixedly connected to the outer wall of the support frame.

[0013] As a further improvement to the above solution, a stepper motor is fixedly connected to the outer end of the worm gear, and a fixing frame is fixedly connected to the outer wall of the stepper motor, which is fixedly connected to the outer wall of the support frame.

[0014] Through the above technical solution, the worm gear meshes with the worm wheel, thereby driving the connecting rod fixedly connected to the worm wheel to rotate. The connecting rod rotates inside the support frame and is fixed to the inspection table, causing the positioning component originally located at the top of the inspection table to rotate to the bottom. Through the flipping action, seamless switching between the upper and lower work positions is achieved, greatly shortening the process interval and thus improving inspection efficiency.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention places the bearing on top of the testing platform. The motor output drives a rotating column to rotate, which in turn drives a rotating ring fixed to the outer wall to rotate stably within a groove on the inner wall of the testing platform. As the rotating column rotates, an arc-shaped guide groove on its outer wall rotates synchronously. This arc-shaped guide groove, through sliding engagement with a sliding rod, causes the sliding rod to slide along the guide groove. Simultaneously, a clamping block fixed to the top of the sliding rod drives a T-shaped slider at the bottom to slide synchronously within a T-shaped groove. This dual-guide structure ensures smooth movement of the clamping block. The three clamping blocks move under the influence of the sliding rod until they are in contact with the inner wall of the bearing, achieving an internal support fixation of the bearing. This internal support fixation avoids the outer ring testing surface of the bearing, completely eliminating obstruction and ensuring that the testing equipment can directly collect data from the entire outer ring surface, improving testing accuracy and reducing testing errors.

[0016] This invention uses a stepper motor to drive a worm gear to rotate. The worm gear rotates stably under the support of a fixed block. The worm gear meshes with a worm wheel, which in turn drives a connecting rod fixedly connected to the worm wheel to rotate. The connecting rod rotates inside the support frame and is fixed to the inspection table, causing the positioning component originally located at the top of the inspection table to rotate to the bottom. Bearings that have been inspected at the bottom can directly enter the next process through the conveying device, while the next bearing can be inspected immediately at the top. There is no need to stop the machine to disassemble the inspected bearings and reinstall new bearings. The flipping action achieves seamless switching between the upper and lower work positions, greatly shortening the process interval and thus improving inspection efficiency.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0020] Please combine Figure 1-5 This embodiment provides a gearbox bearing size detection and positioning bracket, including a detection table 1, a positioning component 2 inside the detection table 1, and a rotating component 3 on the outer wall of the detection table 1. The positioning component 2 includes a guide groove 201, which is located inside the detection table 1. The outer wall of the detection table 1 has a T-shaped sliding groove 202, and the inner wall of the detection table 1 has a rotating groove 203. A rotating ring 204 is rotatably connected to the outer wall of the rotating groove 203. A rotating column 205 is fixedly connected to the inner wall of the rotating ring 204. A motor 206 is fixedly connected to the bottom of the rotating column 205. An arc-shaped guide groove 207 is located at the end of the rotating column 205 away from the motor 206. A sliding rod 208 is slidably connected to the outer wall of the arc-shaped guide groove 207. A clamping block 209 is fixedly connected to the top of the sliding rod 208, and a T-shaped slider 210 is fixedly connected to the bottom of the clamping block 209.

[0021] The motor 206 is fixedly connected to the inner wall of the testing table 1, the sliding rod 208 is slidably connected to the outer wall of the guide groove 201, and the T-shaped slider 210 is slidably connected to the outer wall of the T-shaped slide groove 202.

[0022] The output of motor 206 drives the rotating column 205 to rotate. At the same time, the rotating column 205 drives the rotating ring 204 fixed on the outer wall to rotate stably in the rotating groove 203 on the inner wall of the testing table 1. When the rotating column 205 rotates, the arc-shaped guide groove 207 on its outer wall rotates synchronously. The arc-shaped guide groove 207, through sliding cooperation with the sliding rod 208, drives the sliding rod 208 to slide along the guide groove 201. At the same time, the clamping block 209 fixed at the top of the sliding rod 208 drives the T-shaped slider 210 at the bottom to slide synchronously in the T-shaped sliding groove 202. The three clamping blocks 209 move under the drive of the sliding rod 208 until they fit against the inner wall of the bearing, realizing the internal support fixation of the bearing. The internal support fixation avoids the outer ring testing surface of the bearing, completely eliminating obstruction and ensuring that the testing equipment can directly collect the full surface data of the outer ring, improving the testing accuracy and reducing the testing error.

[0023] The rotating assembly 3 includes a support frame 301, and a connecting rod 302 is rotatably connected inside the support frame 301. The connecting rod 302 is fixedly connected to the outer wall of the testing table 1.

[0024] There are two support frames 301, which are symmetrically arranged with the testing table 1 as the center. There are also two connecting rods 302, which are symmetrically arranged with the testing table 1 as the center.

[0025] A worm gear 303 is fixedly connected to the outer wall of the connecting rod 302, and a worm 304 is meshed with the worm gear 303.

[0026] A fixing block 305 is rotatably connected to the outer wall of the worm gear 304, and the fixing block 305 is fixedly connected to the outer wall of the support frame 301.

[0027] A stepper motor 306 is fixedly connected to the outer end of the worm gear 304. A fixing bracket 307 is fixedly connected to the outer wall of the stepper motor 306. The fixing bracket 307 is fixedly connected to the outer wall of the support frame 301.

[0028] Stepper motor 306 drives worm gear 304 to rotate. Worm gear 304 rotates stably under the support of fixed block 305. Worm gear 304 meshes with worm wheel 303, thereby driving connecting rod 302, which is fixedly connected to worm wheel 303, to rotate. Connecting rod 302 rotates inside support frame 301 and is fixed to inspection table 1, so that positioning component 2, which was originally located at the top of inspection table 1, rotates to the bottom. There is no need to stop the machine to disassemble the inspected bearing and reinstall a new bearing. Seamless switching between upper and lower work positions is achieved through flipping action, which greatly shortens the process interval and improves inspection efficiency.

[0029] The implementation principle of the gearbox bearing size detection and positioning bracket in this embodiment is as follows: The bearing is placed on the top of the detection platform 1. At this time, the output end of the motor 206 drives the rotating column 205 to rotate. At the same time, the rotating column 205 drives the rotating ring 204 fixed on the outer wall to rotate stably in the rotating groove 203 on the inner wall of the detection platform 1, ensuring no deviation during the rotation process. When the rotating column 205 rotates, the arc-shaped guide groove 207 opened on its outer wall rotates synchronously. The arc-shaped guide groove 207 drives the sliding rod 208 to slide along the guide groove 201 through sliding cooperation with the sliding rod 208. At the same time, the clamping block 209 fixed at the top of the sliding rod 208 drives the T-shaped slider 210 at the bottom to slide synchronously in the T-shaped sliding groove 202. The double guide structure ensures that the clamping block 209 moves smoothly. The three clamping blocks 209 move under the drive of the sliding rod 208 until they are in contact with the inner wall of the bearing, realizing the internal support fixation of the bearing. The internal support fixation avoids the detection surface of the outer ring of the bearing, completely eliminating obstruction and ensuring that the bearing is properly fixed. The testing equipment can directly collect data from the entire outer surface, improving testing accuracy and reducing testing errors. Simultaneously, the positioning component 2 is equipped with two sets. After the bearing at the top has been tested, the stepper motor 306, fixed to the inner wall of the fixing frame 307, operates. The stepper motor 306 drives the worm gear 304 to rotate. The worm gear 304 rotates stably under the support of the fixing block 305. The worm gear 304 meshes with the worm wheel 303, thereby driving the connecting rod 302, which is fixedly connected to the worm wheel 303, to rotate. The connecting rod 302 rotates inside the support frame 301 and is fixed to the testing table 1, causing the positioning component 2, originally located at the top of the testing table 1, to rotate to the bottom. The bearings at the bottom that have been tested can directly enter the next process via the conveyor device, while the top can immediately test the next bearing without stopping the machine to disassemble the tested bearings and reinstall new ones. The flipping action achieves seamless switching between the upper and lower workstations, significantly shortening the process interval and thus improving testing efficiency.
