Description

Technical Field

[0001] The utility model relates to the technical field of bearing steel ball technology, in particular to a surface roughness detector for motor bearing steel balls. Background Art

[0002] A surface roughness detector for motor bearing steel balls is a device specifically used to measure the surface roughness of motor bearing steel balls. During the operation of a motor, the quality and performance of the bearings have a crucial impact on the stability and service life of the entire motor. As a key component in the bearings, the surface roughness of the steel balls directly affects the performance of the bearings such as friction, wear, and noise. Therefore, the detection of the surface roughness of motor bearing steel balls is particularly important. This detector uses high-precision sensors and advanced data processing technologies to quickly and accurately measure the surface roughness of the steel balls, providing strong technical support for the production and maintenance of motor bearings.

[0003] In the prior art, the probe of the surface roughness detector for motor bearing steel balls descends too fast and cannot be fine-tuned, which causes many problems. The quickly descending probe is likely to damage the surface of the steel ball to be measured. Especially in precise measurements, subtle scratches or indentations can affect the measurement results and the service performance of the steel ball. In addition, the too-fast descending speed may lead to unstable contact between the probe and the object to be measured, thereby affecting the repeatability and accuracy of the measurement data. The lack of fine-tuning ability limits the flexibility of the operator to adjust according to different measurement requirements, reduces the applicability of the device, and may increase the measurement error. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a surface roughness detector for motor bearing steel balls.

[0005] To achieve the above object, the utility model adopts the following technical solution: A surface roughness detector for motor bearing steel balls, comprising a workbench, a bearing seat, a sliding seat, a detection probe and a fixture seat for the steel ball to be measured. The inner wall of the bearing seat is rotatably connected with a first lead screw and a slide bar. The top of the bearing seat is fixed with a support seat. The inner wall of the support seat is rotatably connected with a first support rod and a second support rod. The bottom of the second support rod is fixedly connected with the top of the first lead screw. The surface of the second support rod is fixed with a first driven gear and a second driven gear. The surface of the first support rod is rotatably connected with a first driving gear and a second driving gear. The surface of the first driven gear meshes with the surface of the first driving gear. The surface of the second driven gear meshes with the surface of the second driving gear. A speed change component is slidably connected to the surface of the first support rod. A flat groove is provided in the slidable area of the speed change component to limit its rotation and prevent self-rotation. Grooves for supporting the sliding of the speed change component into the first driving gear and the second driving gear are provided on one side of each of the first driving gear and the second driving gear. The inner wall of the support seat is rotatably connected with a rotating seat. A driving seat is fixed on one side of the rotating seat. A switching rod is fixed on the other side of the rotating seat. A first bevel gear is fixed on the top of the first support rod. A second bevel gear meshes with the surface of the first bevel gear. The second bevel gear is driven to rotate by a first motor. The first motor is fixed on the top of the support seat. In the prior art, the probe of the surface roughness detector for motor bearing steel balls descends too fast and cannot be finely adjusted, which causes many problems. The rapidly descending probe is likely to damage the surface of the steel ball to be measured. Especially in precision measurement, fine scratches or indentations can affect the measurement result and the service performance of the steel ball. In addition, the too-fast descending speed may lead to unstable contact between the probe and the object to be measured, thus affecting the repeatability and accuracy of the measurement data. The lack of fine adjustment ability limits the flexibility of the operator to adjust according to different measurement requirements, reduces the applicability of the equipment, and may increase the measurement error. To solve such problems, the utility model adopts a fine adjustment structure. When the user needs to quickly lower the probe from top to bottom during the surface roughness detection operation of the motor bearing steel ball, the switching rod is toggled downward to adjust the driving seat to the upper position, so that the speed change component moves upward. When the speed change component rotates, it drives the first driving gear to rotate, which drives the first driven gear to rotate, thereby driving the first lead screw to rotate. When fine adjustment is required, the switching rod is toggled upward to adjust the driving seat to the lower position, so that the speed change component slides downward, driving the second driving gear to rotate, and the second driving gear drives the second driven gear to rotate to achieve fine adjustment. This realizes the precise control of the probe descending speed and the fine adjustment ability, effectively avoids damaging the surface of the steel ball to be measured, ensures the stability and accuracy during the measurement process, improves the repeatability and reliability of the data, increases the applicability of the equipment to measure steel balls of different types and shapes, reduces errors, enhances the flexibility of operation, and improves the functionality and market competitiveness of the equipment.

[0006] Preferably, the surface of the first lead screw is threadedly connected to the sliding seat, the sliding seat is slidably connected to the sliding rod, a detection machine table is fixed on the front surface of the sliding seat, a probe holder is arranged on one side of the detection machine table, a rotating rod is rotatably connected to one side of the probe holder, a probe carrier is fixed on the surface of the rotating rod, a detection member is fixed on the inner wall of the probe carrier, a detection probe is fixed on the surface of the detection member, a through limiting hole is formed in the surface of the probe carrier, the limiting hole is limited by a limiting air cylinder, and the rotating rod is driven to rotate by a second motor, and the second motor is fixed on the inner wall of the probe holder. In the prior art, a surface roughness detector for motor bearing steel balls needs to manually replace probes of different sizes according to the size of the steel balls to be measured. This process is not only cumbersome and time-consuming, but also may cause improper probe replacement due to human factors, affecting the measurement accuracy and efficiency, greatly limiting the flexibility and adaptability of the equipment, increasing the workload of the operator, and being not conducive to quickly and efficiently detecting the surface roughness of steel balls. In view of such problems, the present utility model adopts a replaceable probe structure. When the probe needs to be replaced, the second motor is started to drive the probe carrier to rotate. When the required probe is switched to, the limiting air cylinder is started, and the driving end of the limiting air cylinder is inserted into the limiting hole to limit it, so that the replacement of the detection probe can be completed, enabling the operator to quickly and easily replace the corresponding probe according to the size of the steel ball to be measured, thereby greatly reducing the complexity of the operation and the required time. By simplifying the probe replacement process, the error caused by improper human operation is reduced, the overall measurement accuracy and work efficiency are improved, the flexibility and adaptability of the equipment are enhanced, the workload of the operator is reduced, and it is more conducive to achieving the effect of quickly and efficiently detecting the surface roughness of steel balls.

A second lead screw is rotatably connected to one side of the screw support member. The surface of the second lead screw is rotatably connected to the fixture seat for the steel ball to be measured. Two fixture members are threadedly connected to the surface of the second lead screw. The second lead screw is driven to rotate by a third motor, and the third motor is fixed to the top of the workbench. The threads of the two fixture members are opposite at the threaded connection. Fixture limiting grooves are formed on one side of each of the two fixture members, and a bottom limiting groove is formed on the top of the fixture seat for the steel ball to be measured. In the prior art, the surface roughness detector for motor bearing steel balls does not have a dedicated fixture for the steel ball to be measured, which brings a series of problems. Without a dedicated fixture, the position of the steel ball may be unstable during the measurement process, affecting the measurement accuracy and repeatability. The operator needs to manually fix the steel ball, which not only increases the operation complexity but also may introduce additional measurement errors due to manual operation. In addition, the lack of a universal or adjustable fixture suitable for steel balls of different sizes and materials limits the applicable range of the detector, reducing the flexibility and applicability of the device. To address such problems, the utility model adopts a steel ball fixture structure. When performing the surface roughness detection of motor bearing steel balls, the steel ball to be measured is placed on the bottom limiting groove, and then the third motor is started. The third motor drives the second lead screw to rotate to drive the two fixture members with opposite threads to clamp the steel ball to be measured. After the fixture limiting grooves are clamped and engaged with the steel ball, clamping can be achieved, significantly improving the position stability of the steel ball during the measurement process, thereby enhancing the measurement accuracy and repeatability, simplifying the operation process, reducing the need for the operator to manually fix the steel ball, and reducing the additional measurement errors that may be introduced due to manual operation. At the same time, the design takes into account the universality or adjustability of steel balls of different sizes and materials, ensuring the wide applicability of the fixture, expanding the applicable range of the detector, and enhancing the flexibility and applicability of the device.

[0009] Preferably, the detection member is fixed to the inner wall of the probe carrier by screws. Fixing the detection member to the inner wall of the probe carrier by screws is beneficial for the simple replacement of the detection member, achieving the effect that when the detection member fails, the detection member can be replaced conveniently.

[0010] Preferably, the detection machine table is fixed to the front of the sliding seat by screws. Fixing the detection machine table to the front of the sliding seat by screws is beneficial for the simple replacement of the detection member, achieving the effect that when the detection machine table fails, the detection machine table can be replaced conveniently.

[0011] Preferably, fixture rubber pads are fixed on one side of each of the two fixture pieces, achieving the effects of providing better fixing and protection, preventing the steel balls from moving or being damaged during the measurement process, ensuring the stability of the measurement process and the integrity of the steel ball surface, thereby improving the accuracy and reliability of the measurement.

The first motor 117 is fixed to the top of the support seat 104.In the prior art, the probe of the motor bearing steel ball surface roughness tester descends too fast and cannot be fine-tuned, which causes many problems. The fast-descending probe is easy to damage the surface of the steel ball being tested, especially in precision measurement, where slight scratches or indentations can affect the measurement results and the performance of the steel ball. In addition, too fast a descent speed may cause unstable contact between the probe and the object being tested, thereby affecting the repeatability and accuracy of the measurement data. The lack of fine-tuning capability limits the operator's flexibility to adjust according to different measurement requirements, reduces the applicability of the equipment, and may increase measurement errors. To address such problems, the utility model adopts a fine-tuning structure. When the user needs to quickly lower the probe from top to bottom when performing the motor bearing steel ball surface roughness detection operation, the user can push the switch lever 111 downward to adjust the drive seat 110 to the top, so that the speed change component 1 08 moves upward, and when the speed change component 108 rotates, it drives the first driving gear 106 to rotate, and drives the first driven gear 113 to rotate, thereby driving the first screw rod 102 to rotate.

In the prior art, for a motor bearing steel ball surface roughness detector, different-sized probes need to be manually replaced according to the size of the steel ball to be measured. This process is not only cumbersome and time-consuming, but also may lead to improper probe replacement due to human factors, affecting the measurement accuracy and efficiency. This greatly limits the flexibility and adaptability of the equipment, increases the workload of the operator, and is not conducive to quickly and efficiently detecting the surface roughness of steel balls. To address such problems, the present utility model adopts a replaceable probe structure. When a probe needs to be replaced, the second motor 208 is started to drive the probe carrier 204 to rotate. When the required probe is switched to, the limiting air cylinder 209 is started. The driving end of the limiting air cylinder 209 is inserted into the limiting hole 207 to limit it, and thus the replacement of the detection probe can be completed. This allows the operator to quickly and easily replace the corresponding probe according to the size of the steel ball to be measured, thereby greatly reducing the complexity of the operation and the required time.

When the speed change assembly 108 rotates, it drives the first driving gear 106 to rotate, drives the first driven gear 113 to rotate, and thus drives the first lead screw 102 to rotate. When fine adjustment is required, toggle the switching lever 111 upward to adjust the driving seat 110 to the lower position, so that the speed change assembly 108 slides downward, drives the second driving gear 107 to rotate, and makes the second driving gear 107 drive the second driven gear 114 to rotate to achieve fine adjustment.
