Description

Technical Field

[0001] This utility model relates to the field of bearing testing technology, and in particular to a bearing outer ring height and outer diameter testing device. Background Technology

[0002] With the increasing demands for bearing precision in the machinery manufacturing industry, the accuracy and efficiency of measuring the bearing outer ring height and outer diameter have become key factors affecting the quality control of bearing products.

[0003] Most bearing outer ring testing devices on the market today are based on the core testing principle of using a stylus and a test gauge to measure the outer diameter error. However, they have significant shortcomings in the auxiliary structure design for driving the rotation of the bearing outer ring and adjusting the position of the components. The traditional method of manually rotating the bearing outer ring is greatly affected by human operation factors. Not only is it difficult to guarantee the testing accuracy, but it also requires the operator to continuously focus on the rotation action, which increases labor costs and operator fatigue.

[0024] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Reference Figures 1-4A bearing outer ring height and outer diameter detection device includes a base 1, on which a detection mechanism is mounted. The detection mechanism includes a first contact pin assembly 23, a second contact pin assembly 24, and a detection gauge 25, used to detect the outer diameter of the bearing outer ring. It should be noted that the first contact pin assembly 23 is movably mounted on the base 1, and includes a movable seat, a first contact pin, and a first locking bolt. Specifically, when the first contact pin contacts the outer wall of the bearing outer ring, the first locking bolt fixes the movable seat to a designated position on the base 1. The second contact pin assembly 24 includes a first mounting base, a second contact pin, and a second locking bolt. The second contact pin is made to abut against the outer wall of the bearing outer ring, and the second locking bolt is used to fix the position of the second contact pin on the first mounting base. The test gauge 25 is connected to the base 1 through the second mounting base and cooperates with the first contact pin assembly 23 and the second contact pin assembly 24 to achieve three-point contact with the outer wall of the bearing outer ring. The test gauge 25 is used to detect the error of the outer diameter of the bearing outer ring. It is a basic test component of the existing product. The base 1 is equipped with a bearing rotation drive assembly.

[0026] The bearing rotation drive assembly includes a second fixing block 13, on which a first rotating shaft 14 is rotatably mounted, and a power source is provided at the end of the first rotating shaft 14 for driving the first rotating shaft 14 to rotate. Preferably, it is a micro motor with self-locking, and a ring block 15 is provided at the bottom of the first rotating shaft 14.

[0027] Furthermore, the ring block 15 is provided with a bearing inner wall clamping assembly for clamping the bearing outer ring from the inside.

[0028] Specifically, after the bearing outer ring is installed between the testing mechanisms, the first contact pin assembly 23, the second contact pin assembly 24, and the contact pin in the test gauge 25 are brought into contact with the outer wall of the bearing outer ring. The position of the bearing rotation drive assembly is adjusted, and the bearing inner wall clamping assembly clamps the bearing from the inner wall. Then, the first rotating shaft 14 is driven to rotate, which in turn drives the ring block 15 to rotate. The ring block 15 drives the bearing outer ring to rotate stably at a constant speed through the bearing rotation drive assembly. The error of the outer diameter of the bearing outer ring is detected by observing the position of the pointer of the test gauge 25. Compared with the existing method that requires manually rotating the bearing outer ring, this method is more stable and ensures more accurate test results.

[0029] Furthermore, the bearing rotation drive assembly includes a plurality of slide rods 19 slidably disposed on the ring block 15, and the plurality of slide rods 19 are arranged in a ring array. Each slide rod 19 is provided with a pressing block 22 at its end. It should be noted that the pressing block 22 is preferably made of rubber with a high coefficient of friction, and is used to clamp the bearing outer ring from the inner wall of the bearing outer ring.

[0030] The bearing rotation drive assembly includes a fixed frame 16 mounted on the ring block 15. A sleeve 17 is rotatably connected to the fixed frame 16, and the sleeve 17 is sleeved on the outside of the first rotating shaft 14. The fixed frame 16 is provided with a power source for driving the sleeve 17 to rotate, preferably a micro motor. The micro motor is also self-locking. A cam 18 is provided at the bottom end of the sleeve 17, and the cam 18 is used to push the slide rod 19 to slide.

[0031] Specifically, by driving the sleeve 17 to rotate, the sleeve 17 drives the cam 18 to rotate, which in turn pushes multiple slide rods 19 to slide relative to the ring block 15 until the pressing block 22 on the slide rod 19 abuts against the inner wall of the outer ring of the bearing and clamps it.

[0032] Furthermore, the base 1 is provided with an X-axis adjustment assembly, a Y-axis adjustment assembly, and a Z-axis adjustment assembly, wherein,

[0033] The X-axis adjustment assembly includes a first connecting seat 2 disposed on the side wall of the base 1, located directly opposite the measuring gauge 25. A first lead screw 3 is rotatably disposed on the inner side of the first connecting seat 2. A power source, preferably a manually driven handwheel, is disposed at the end of the first lead screw 3. A first threaded block 4 is threadedly connected to the first lead screw 3, and a sliding groove adapted to the first threaded block 4 is provided on the first connecting seat 2, which can restrict the first threaded block 4 from rotating together with the first lead screw 3.

[0034] Specifically, by driving the first lead screw 3 to rotate, the first threaded block 4 moves relative to the first connecting seat 2, and through the transmission of the Y-axis adjustment component and the Z-axis adjustment component, the bearing rotation drive component is driven to adjust the position in the X-axis direction.

[0035] Furthermore, the Y-axis adjustment assembly includes a connecting frame 5 mounted on a first threaded block 4, a second connecting seat 6 mounted on the connecting frame 5, a second lead screw 7 rotatably mounted on the inner side of the second connecting seat 6, and a power source, preferably a manually driven handwheel, mounted on the end of the second lead screw 7. A second threaded block 8 is threadedly connected to the second lead screw 7, and a slider 9 is mounted on the second threaded block 8. The second connecting seat 6 has a groove that matches the slider 9, which can restrict the slider 9 from rotating with the second lead screw 7.

[0036] Specifically, by driving the second lead screw 7 to rotate, the position of the second threaded block 8 is adjusted. Then, through the transmission of the Z-axis adjustment component, the bearing rotation drive component is driven to adjust the position in the Y-axis direction. In cooperation with the X-axis adjustment component, the position of the bearing rotation drive component in the X and Y axes is adjusted to the center position of the bearing outer ring, so as to facilitate the clamping of the bearing outer ring.

[0037] Furthermore, the Z-axis adjustment assembly includes a first fixing block 10 disposed on the second threaded block 8. A lifting rod 12 is slidably disposed on the first fixing block 10. The bottom of the lifting rod 12 is fixedly connected to the second fixing block 13. The first fixing block 10 is provided with a threaded groove. A bolt 11 for fixing the position of the lifting rod 12 is disposed inside the threaded groove. The lifting rod 12 is fixed by the end of the bolt 11 abutting against the side wall of the lifting rod 12 and by friction.

[0038] Specifically, by loosening bolt 11 and adjusting the height of shaft adjustment lifting rod 12, the bearing rotation drive assembly below is driven to adjust its position in the Z-axis direction. During the process of placing the bearing outer ring in the testing mechanism, the bearing rotation drive assembly is raised to avoid obstructing the bearing outer ring installation space. After the bearing outer ring is installed, the bearing rotation drive assembly is adjusted downward to be at the same height as the bearing for easy clamping.

[0039] Furthermore, a spring 21 is provided on the outer side of each slide bar 19, and the spring 21 is located between the ring block 15 and the pressing block 22 for resetting the slide bar 19.

[0040] Furthermore, each of the slide bars 19 is provided with a roller 20 at the end away from the extrusion block 22, and the contact surface between the cam 18 and the roller 20 is an arc surface.

[0041] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
