The background technology involves the accurate detection and quality control of bearing clearance. As mechanical equipment develops towards high speed and precision, the control of bearing clearance is of great significance to the stability and service life of the whole machine. Digital measurement technology, through the combination of sensors and digital display devices, can realize the rapid, intuitive and high-precision detection of the clearance between the inner and outer rings of the bearing, meeting the dual requirements of efficiency and accuracy in modern production, and facilitating data recording and analysis, providing a reliable basis for bearing matching and selection.

[0003] In existing technologies, when it is necessary to detect the clearance in different horizontal areas of a bearing, it is impossible to achieve continuous and accurate measurement switching through smooth horizontal movement. It is also difficult to accurately align the measuring device with the detection points at different horizontal positions of the bearing, which easily leads to horizontal positioning deviations. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a bearing pairing digital clearance measuring instrument, including a measuring platform, a fixing structure, and a detection structure. The fixing structure and the detection structure are respectively installed on the top of the measuring platform. The detection structure includes a support block, a mounting frame, and a second motor. A first lead screw is rotatably installed between the support blocks. First guide rails are fixedly installed between the support blocks and on both sides of the first lead screw. A sliding plate is threaded onto the first lead screw. The two ends of the sliding plate are slidably connected to the first guide rails. A second lead screw is installed on the mounting frame via the second motor. Second guide rails are fixedly installed on both sides of the inner wall of the mounting frame. A threaded block is threaded onto the second lead screw. The two ends of the threaded block are slidably connected to the second guide rails. The measuring instrument is installed on the threaded block via a mounting plate.

[0006] As a preferred embodiment of the bearing pairing digital clearance measuring instrument of this utility model, the fixed structure includes a mounting groove, a turntable, a first motor and an electric push rod. The mounting groove is opened in the middle of the top of the measuring platform. The turntable is rotatably installed inside the mounting groove. The first motor is fixedly installed at the bottom of the measuring platform. The motor shaft of the first motor passes through the measuring platform and is fixedly connected to the turntable. The motor shaft of the first motor is rotatably connected to the measuring platform.

[0007] In a preferred embodiment of the bearing pairing digital clearance measuring instrument of this utility model, a threaded rod is fixedly installed at the top center of the turntable, and a pressure plate is threaded onto the threaded rod.

[0008] In a preferred embodiment of the bearing pairing digital clearance measuring instrument of this utility model, the electric push rods are configured as a pair, and the electric push rods are fixedly installed on the top of the measuring table by a fixing frame, and clamping blocks are fixedly installed on the telescopic ends of the electric push rods on both sides of the turntable.

[0009] In a preferred embodiment of the bearing pairing digital clearance measuring instrument of this utility model, the support blocks are configured as a pair and fixedly installed on the top of the measuring table. One end of the first lead screw extends through the support block to the outside of the support block, and a handwheel is fixedly installed on the outside end of the first lead screw.

[0012] The beneficial effects of this utility model are:

[0013] 1. Through the set detection structure, the first lead screw is driven by rotating the handwheel to move the slide plate horizontally along the first guide rail. The second lead screw is driven by the second motor to move the threaded block up and down along the second guide rail. The horizontal and vertical positions of the measuring instrument can be precisely adjusted to ensure that it is accurately aligned with the bearing to be tested, thereby improving the measurement accuracy. The measuring instrument is a digital measuring device that can directly obtain accurate digital measurement results, reducing manual reading errors.

[0024] Refer to attached figure Figure 1 - Appendix Figure 4This is the first embodiment of the present invention, which provides a bearing pairing digital clearance measuring instrument, including a measuring platform 1, a fixing structure 2, and a detection structure 3. The fixing structure 2 and the detection structure 3 are respectively installed on the top of the measuring platform 1. The fixing structure 2 includes a mounting groove 201, a turntable 202, a first motor 203, and an electric push rod 206. The mounting groove 201 is opened in the middle of the top of the measuring platform 1. The turntable 202 is rotatably installed inside the mounting groove 201. The first motor 203 is fixedly installed at the bottom of the measuring platform 1. The motor shaft of the first motor 203 passes through the measuring platform 1 and is fixedly connected to the turntable 202. The motor shaft of the first motor 203 is rotatably connected to the measuring platform 1. A threaded rod 204 is fixedly installed at the center of the top of the turntable 202. A pressure plate 205 is threadedly installed on the threaded rod 204. The electric push rods 206 are configured as a pair. The electric push rods 206 are fixedly installed on the top of the measuring platform 1 through a fixing bracket 207. Clamping blocks 208 are fixedly installed on the telescopic ends of the electric push rods 206 on both sides of the turntable 202.

[0025] During use, the pressure plate 205 is removed, the bearing is placed on the turntable 202, and the inner ring of the bearing is pressed down by rotating the pressure plate 205. At the same time, the electric push rods 206 on both sides are activated, and the telescopic ends of the electric push rods 206 push the clamping block 208 to clamp the outer ring of the bearing to achieve fixation. Example 2

[0026] Refer to attached figure Figure 1 and attached Figure 5 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0027] The detection structure 3 includes a support block 301, a mounting bracket 305, and a second motor 307. The support blocks 301 are a pair and fixedly mounted on the top of the measuring table 1. A first lead screw 302 is rotatably mounted between the support blocks 301. One end of the first lead screw 302 passes through the support block 301 and extends to the outside of the support block 301. A handwheel is fixedly mounted on the outer end of the first lead screw 302. First guide rails 303 are fixedly mounted between the support blocks 301 and on both sides of the first lead screw 302. A sliding plate 304 is threaded onto the first lead screw 302. Both ends of the sliding plate 304 are slidably connected to the first guide rails 303. The mounting bracket 3... 05 is fixedly installed on the top of the slide plate 304. The second lead screw 306 is rotatably installed inside the mounting bracket 305. The second motor 307 is fixedly installed on the top of the mounting bracket 305, and the motor shaft of the second motor 307 is fixedly connected to the top of the second lead screw 306. The second guide rails 308 are fixedly installed on both sides of the inner wall of the mounting bracket 305. The threaded block 309 is threadedly installed on the second lead screw 306.

The measuring instrument 311 is fixedly installed on the mounting plate 310. The measuring instrument 311 is a digital measuring device.

[0028] During use, by rotating the handwheel on the first lead screw 302, the slide plate 304 can move horizontally along the first guide rail 303, driving the mounting bracket 305 and measuring instrument 311 to adjust their horizontal positions. The second motor 307 is then started, and the motor shaft of the second motor 307 drives the second lead screw 306 to rotate, causing the threaded block 309 to move up and down along the second guide rail 308. This causes the measuring instrument 311 on the mounting plate 310 to adjust its vertical height, thereby accurately aligning the measuring instrument 311 with the bearing to be tested. In conjunction with the fixing structure 2, the bearing clearance measurement operation is completed. After the measuring instrument 311 finishes testing one side of the bearing, the telescopic end of the electric push rod 206 retracts, releasing the clamping block 208 from fixing the outer ring of the bearing. The first motor 203 can then drive the turntable 202 to rotate the bearing, facilitating the measuring instrument 311 to test other positions of the bearing.
