Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing component testing technology, specifically to a bearing component processing and testing device. Background Technology
[0002] Bearing components are essential parts of a bearing system, including adapter sleeves, withdrawal sleeves, lock nuts, locking devices, bearing housings, and thrust rings. These components work in conjunction with the bearing body to ensure stable bearing operation in mechanical equipment. For example, adapter sleeves and withdrawal sleeves are used for positioning and removing tapered bore bearings from cylindrical shafts, while lock nuts are used to secure the bearing and prevent axial movement. The purpose of machining and inspecting bearing components is to ensure their accuracy, reliability, and service life. Strict control over dimensional accuracy, geometric accuracy, and form and position tolerances is required during machining. Precision metrology and instrument testing ensure that components meet design requirements. Inspection items include visual inspection, dimensional measurement, hardness testing, and non-destructive testing to detect potential defects such as cracks, wear, and corrosion. Rigorous machining and inspection can effectively prevent bearing failures caused by component quality issues, ensure the normal operation of mechanical equipment, extend equipment life, and reduce maintenance costs.
[0003] A search revealed that CN221223610U discloses an elevator component bearing testing device, comprising a platform, a machine base, a placement table on the inner side of the machine base, a support rod fixedly connected to the upper surface of the machine base, and a first fixing sleeve fixedly connected to the top of the support rod. This invention, through the setting of a limiting block, can limit the elevator component bearing on the placement table, preventing the bearing from shifting during testing and thus ensuring testing stability. Simultaneously, by driving a screw to rotate via a first motor, a moving block can be moved, which in turn moves a movable rod, allowing the movable rod to move the fixed rod and the limiting block. This enables the limiting block to limit different types of elevator component bearings, improving the flexibility of fixing the bearings and thus improving testing performance.
[0004] The aforementioned elevator component bearing testing device uses a screw-driven limit block for linear movement, which can only achieve horizontal position adjustment and cannot meet the testing requirements of the circumferential surface or irregular structure of bearing components. At the same time, this design relies solely on a motor or manual fixation, which can easily lead to measurement position deviation due to external forces or vibrations during continuous testing. Summary of the Invention
[0005] This utility model proposes a bearing component processing and testing device, which solves the problems of the single detection position adjustment and the lack of stability of height adjustment in the prior art.
[0006] The technical solution of this utility model is as follows: A bearing accessory processing and testing device includes a processing and testing table and a dial indicator body disposed above the processing and testing table. A rotating component is disposed inside the processing and testing table. The rotating component includes a main gear disk that can rotate horizontally. The rotating component also includes a support frame fixedly connected to one side of the top of the main gear disk for support. A lifting component is disposed on the top of the support frame. The lifting component includes a slide that can move vertically and be locked and used in assembly with the dial indicator body.
[0007] Preferably, the rotating assembly further includes a first forward and reverse motor, which is fixedly installed inside the processing and testing table. The rotating assembly also includes a first rotating shaft, which is fixedly connected to the output end of the first forward and reverse motor.
[0008] Preferably, the rotating assembly further includes a secondary gear disk, the bottom of which is fixedly connected to the first rotating shaft, and the secondary gear disk is in contact with and meshed with the main gear disk.
[0009] Preferably, the lifting assembly includes a support base, which is fixedly connected to the support frame.
[0010] Preferably, the lifting assembly further includes two sets of side sleeves, which are fixedly connected to the outside of the support, and the lifting assembly further includes a second rotating shaft, which is rotatably connected to the inside of the two sets of side sleeves.
[0011] Preferably, the lifting assembly further includes a second forward and reverse motor, which is fixedly installed on the top of the upper side sleeve, and the output end of the second forward and reverse motor is fixedly connected to the second rotating shaft.
[0012] Preferably, the lifting assembly further includes a worm gear, which is fixedly connected to the outside of the second rotating shaft, and the lifting assembly further includes a rotating column, which is rotatably connected to the inside of the support.
[0013] Preferably, the lifting assembly further includes a worm gear, which is fixedly connected to one end of the rotating column, and the worm gear and the worm are meshed and rotatably connected. The lifting assembly also includes a gear, which is fixedly connected to the other end of the rotating column.
[0014] Preferably, the lifting assembly further includes ball bearings, which are rotatably connected to both sides of the slide at equal intervals. The slide is slidably connected to the inner side of the support via the ball bearings. The lifting assembly also includes a toothed groove group, which is evenly distributed on the side of the slide. The toothed groove group contacts the gear and is meshed with it for transmission.
[0015] Preferably, the lifting assembly further includes a mounting sleeve, which is fixedly connected to the lower outer side of the slide block.
[0016] The beneficial effects of this utility model are as follows:
[0017] I. Multi-degree-of-freedom detection and adjustment capability: This patent achieves horizontal rotation adjustment of the dial indicator through a main gear plate and a secondary gear plate of the rotating component. Combined with the vertical movement of the lifting component, it can perform multi-angle and multi-position detection of bearing components. In contrast, the prior art only uses the linear movement of the limit block driven by the screw, limiting the detection range to a single plane and failing to meet the multi-directional measurement needs of complex-shaped components. Innovation: The two-way linkage design of rotation and lifting breaks through the limitations of the single-dimensional adjustment of the prior art. II. Self-locking stable adjustment mechanism: The lifting component of this patent uses a worm gear and worm wheel meshing transmission. Utilizing its self-locking characteristic, the slide position is automatically locked after the height is adjusted, avoiding displacement caused by vibration or gravity during the detection process. The prior art relies on the simple cooperation of the screw and the moving rod, lacking a self-locking mechanism, which poses a risk of the limit block loosening during measurement. Innovation: The worm gear and worm wheel transmission replaces the ordinary screw, improving adjustment stability and accuracy. Attached Figure Description

[0027] This design solves the problems of limited detection dimensions and insufficient stability in comparative document detection through the coordinated design of rotation and lifting components.
[0028] Please see Figure 3 The rotating assembly 2 also includes a first forward and reverse motor 21, which is fixedly installed inside the processing and testing table 1.

[0030] The lifting assembly 3 includes a support 31, which is fixedly connected to the support frame 231;
[0031] This design allows the support frame 231 located on one side of the top of the main gear plate 23 to drive the lifting assembly 3 and the dial indicator body 4 mounted on the outside of the lifting assembly 3 to rotate and move rapidly above the bearing accessories.
[0032] The main gear plate 23 drives the support frame 231 to rotate, so that the dial indicator body 4 can be freely adjusted around the bearing accessories in the circumference, covering the annular detection path such as the bearing raceway detection.
[0033] Please see Figure 4 and Figure 5The lifting assembly 3 also includes two sets of side sleeves 34, which are fixedly connected to the outside of the support 31. The lifting assembly 3 also includes a second rotating shaft 33, which is rotatably connected to the inside of the two sets of side sleeves 34.
[0034] The lifting assembly 3 also includes a second forward and reverse motor 32, which is fixedly installed on the top of the upper side sleeve 34, and the output end of the second forward and reverse motor 32 is fixedly connected to the second rotating shaft 33.

[0037] The lifting assembly 3 also includes ball bearings 361, which are rotatably connected to both sides of the slide block 36 at equal intervals. The slide block 36 is slidably connected to the inner side of the support 31 through the ball bearings 361. The lifting assembly 3 also includes a toothed groove group 363, which is evenly distributed on the side of the slide block 36. The toothed groove group 363 is in contact with the gear 352 and is meshed and connected.
[0038] The worm gear drive of the lifting assembly has a self-locking capability, and the meshing of gear 352 and tooth set 363 further strengthens the positioning rigidity of slide 36, ensuring the measurement stability of dial indicator in the vertical direction.
[0039] By providing ball bearings 361 on the outside of the slide 36 that contact the inside of the support 31, the vertical movement of the slide 36 on the inside of the support 31 can be made smoother.

Through this design, the height of the slide 36 and the dial indicator body 4 assembled at the mounting sleeve 362 can be quickly adjusted.
[0043] Working principle:
[0044] The first forward and reverse motor 21 is started to drive the first rotating shaft 211 and the auxiliary gear disk 22 to rotate.

Through this design, the support frame 231 located on the top side of the main gear disk 23 can drive the lifting component 3 and the dial indicator body 4 mounted on the outside of the lifting component 3 to rotate and move quickly above the bearing accessories.
[0045] The second forward and reverse motor 32 is activated to drive the second rotating shaft 33 and the worm gear 331 to rotate in the middle of the two sets of side sleeves 34. At this time, under the meshing cooperation of the worm gear 331 and the worm wheel 351, the rotating column 35 located in the middle of the worm wheel 351 will rotate synchronously. The self-locking effect generated between the worm gear 331 and the worm wheel 351 can prevent loosening after rotating to the target angle. When the rotating column 35 rotates, the gear 352 located at the other end of the rotating column 35 will rotate synchronously.
