Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing precision testing technology, and in particular to a precision testing device for bearing production. Background Technology
[0002] A bearing is an important component used in mechanical transmission. Its main function is to support rotating shafts or other moving parts, reduce friction and wear during movement, and ensure the accurate movement and positioning of the parts. It consists of an inner ring, an outer ring, rolling elements, and a cage. The inner ring mates with the shaft, and the outer ring mates with the bearing housing or a hole in the mechanical part. The rolling elements roll between the inner and outer rings, and the cage evenly separates the rolling elements so that they can roll smoothly.
[0003] Precision testing equipment for bearing production is used to ensure the quality and precision of bearing manufacturing. It has multiple functions, enabling precise measurement and analysis of various key bearing parameters. For example, a dimensional measuring device can accurately detect the inner diameter, outer diameter, and width of the bearing to ensure it meets design requirements; a roundness measuring instrument can measure the roundness of the bearing raceway and inner and outer rings to determine if there are shape errors; and a surface roughness measuring instrument is used to detect the surface roughness of the bearing, ensuring good surface quality and reducing friction and wear. Previously, bearing production precision testing was done manually using various measuring rulers. Now, this work is accomplished using various precision testing equipment for bearing production. However, the probes for detecting bearing roundness in existing precision testing equipment are directly welded to the equipment. This fixed method cannot be adjusted for bearings of different sizes, resulting in insufficient versatility. Utility Model Content

[0008] As a further description of the above technical solution:
[0009] Multiple anti-slip sleeves are equidistantly installed on the outer wall of the handle, and the left and right ends of the multiple anti-slip sleeves are fixedly connected with Velcro.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figure 3This utility model provides an embodiment of a precision testing device for bearing production, comprising a body 1, a fixed shell 3 fixedly connected to the middle of the body 1, a rotating rod 4 rotatably connected to the middle of the fixed shell 3, a rotating handle 5 fixedly connected to the bottom of the rotating rod 4, two gears 6 fixedly connected at equal intervals to the outer wall of the rotating rod 4, and the rotating handle 5 driving the two gears 6 to rotate through the rotating rod 4. Slide grooves 7 are provided around the outer wall of the fixed shell 3, and racks 8 are slidably connected to the inner sides of the multiple slide grooves 7. The slide grooves 7 on the fixed shell 3 are used to install racks 8, and adjacent sides of the multiple racks 8 are respectively meshed with corresponding gears 6. The gears 6 drive the racks 8 to slide within the slide grooves 7. Convenient replacement mechanisms 2 are installed on the outer sides of the racks 8 for convenient probe replacement. Multiple anti-slip sleeves 9 are installed at equal intervals on the outer wall of the rotating handle 5, and Velcro 10 is fixedly connected to the left and right ends of the multiple anti-slip sleeves 9 for preventing slippage of the rotating handle 5.
[0032] Specifically, rotating the handle 5 fixed under the rotating rod 4 causes the rotating rod 4 to rotate. When the rotating rod 4 rotates, the two gears 6 fixed on it will also rotate synchronously. When the two gears 6 start to rotate, they will drive the rack 8 installed in the slide groove 7 in the fixed shell 3 to slide outward through meshing. The probe moves outward by the outward sliding of multiple racks 8. The anti-slip sleeve 9 fixed to the outside of the handle 5 by the Velcro 10 can improve the anti-slip performance of the handle 5.
[0033] Reference Figure 4 and Figure 5 The convenient replacement mechanism 2 includes a housing 201. Multiple housings 201 are fixedly connected to the ends of corresponding racks 8. Multiple fixing blocks 202 are equidistantly slidably connected to the lower inner sides of the housings 201, and the fixing blocks 202 slide within the housings 201. Turntables 203 are rotatably connected to the upper middle parts of the housings 201. Multiple adjusting rods 204 are equidistantly fixedly connected to the tops of the turntables 203. Rotating rings 205 are fixedly connected to the tops of the adjusting rods 204. The rotating rings 205 are connected to the adjusting rods 204. The turntable 203 rotates inside the housing 201. Detection needles 206 are slidably connected to the inner sides of multiple housings 201. Rubber sleeves 11 are fixedly connected to the outer walls of multiple rotating rings 205. Anti-slip textures 12 are provided on the outer walls of multiple rubber sleeves 11. The rubber sleeves 11 and anti-slip textures 12 can improve the grip of the rotating rings 205. Limiting pieces 13 are fixedly connected to the tops of multiple detection needles 206. Pull rings 14 are fixedly connected to the tops of multiple limiting pieces 13. Detection needles 206 can be easily pulled out through the pull rings 14.
[0034] Specifically, when the rotating ring 205 rotates, the multiple adjusting rods 204 fixed below it will also be driven to rotate. When the multiple adjusting rods 204 rotate, the turntable 203 fixed below it will also be driven to rotate inside the housing 201. When the turntable 203 rotates inside the housing 201, it will also drive the multiple fixing blocks 202 to slide inside the housing 201 through its groove. When the multiple fixing blocks 202 slide outward, the detection needle 206 will be pulled out from the housing 201 for replacement. Then, the rotating ring 205 is rotated in the opposite direction, and the multiple fixing blocks 202 will slide inward through the adjusting rods 204 and the turntable 203 to fix the new detection needle 206. The rubber sleeve 11 fixed outside the rotating ring 205 can improve its grip, and the anti-slip texture 12 on the outside of the rubber sleeve 11 can improve the anti-slip property of the rubber sleeve 11. The limiting piece 13 can prevent the detection needle 206 from falling downward, and the pull ring 14 can pull out the detection needle 206 more quickly.
[0035] Reference Figure 1 and Figure 2 A display screen 15 is fixedly connected to the right side of the top wall of the machine body 1. An operation key 16 is installed at the front end of the right side of the top wall of the machine body 1. The bearing production precision testing device can be operated through the operation key 16 and the display screen 15. A detection groove 17 is opened in the middle of the top wall of the machine body 1. Two indicator lights 18 are fixedly connected at equal intervals on the left side of the top wall of the machine body 1. The indicator lights 18 can indicate the status of the bearing production precision testing device. Support rods 19 are fixedly connected to the four corners of the bottom of the machine body 1. Protective pads 20 are fixedly connected to the bottom of the multiple support rods 19. The support rods 19 and the protective pads 20 provide support for the machine body 1 of the bearing production precision testing device.
[0036] Specifically, the display screen 15 can view the data detected by the bearing production precision testing device, the operation key 16 can control the bearing production precision testing device, the testing slot 17 is used to place the bearing to be tested, the indicator light 18 can indicate the current status of the bearing production precision testing device, the support rod 19 provides support for the machine body 1, and the protective pad 20 can provide protection for the support rod 19.
[0037] Working principle: When using the precision testing device for bearing production to test bearings of different sizes, first rotate the handle 5 fixed under the rotating rod 4. The rotation of the handle 5 drives the rotation of the rotating rod 4. When the rotating rod 4 rotates, the two gears 6 fixed on it will also rotate synchronously. When the two gears 6 start to rotate, they will drive the rack 8 installed in the slide groove 7 in the fixed housing 3 to slide outward through meshing. The outward sliding of multiple racks 8 drives the probe to move outward, thereby achieving the effect of adjusting the probe spacing of the precision testing device for bearing production.
[0038] When it is necessary to replace the probe of the precision testing device used in bearing production, first rotate the rotating ring 205. When the rotating ring 205 rotates, the multiple adjusting rods 204 fixed under it will also be driven to rotate. When the multiple adjusting rods 204 rotate, the turntable 203 fixed under it will also be driven to rotate inside the housing 201. When the turntable 203 rotates inside the housing 201, it will also drive the multiple fixing blocks 202 to slide inside the housing 201 through its groove. When the multiple fixing blocks 202 slide outward, the detection needle 206 will be pulled out from the housing 201 for replacement. Then, rotate the rotating ring 205 in the opposite direction, and drive the multiple fixing blocks 202 to slide inward through the adjusting rods 204 and the turntable 203 to fix the new detection needle 206. This achieves the convenient replacement of the detection needle 206.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
