Description

Technical Field

[0001] This invention relates to the field of industrial precision testing technology, and more specifically to a device for rapid and stable testing of Barkhausen noise equipment. Background Technology

[0002] In the field of industrial precision inspection, magnetoelastic testing technology based on the Barkhausen effect has been widely used for surface quality assessment of metal parts. The Barkhausen Rollscan 350 testing equipment, as a representative instrument in this field, is mainly used to detect grinding defects and heat treatment quality in key components such as bearings and gears. However, existing equipment still relies on manual operation. During the testing process, parameters such as the contact state between the probe and the workpiece (e.g., contact area, relative angle) and the scanning speed are easily affected by human factors, leading to significant fluctuations in the magnetoelastic (MP) value detection results. This instability of manual operation not only reduces measurement efficiency but also results in inconsistent and unreliable test data, making it difficult to meet the high-precision requirements for parts quality control in modern manufacturing processes. This has become a technical bottleneck restricting product quality traceability and improving mass production efficiency. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a device for rapid and stable testing of Barkhausen noise equipment. By setting a sliding probe and positioning components to form a clamping structure, it achieves stable clamping and rotation testing of the bearing rings under test, reduces human interference, and improves the consistency and reliability of test data.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a device for rapid and stable testing of Barkhausen noise equipment, comprising a base, a probe slidably mounted on the base, and a positioning component mounted on the base. The probe and the positioning component are combined to form a clamping structure for holding the bearing race under test. During testing, the probe is connected to an external device, and the probe is slid to abut against the bearing race. The bearing race is clamped in the clamping structure. Then, the bearing race is manually rotated, and the magnetoelastic value MP detected by the device is recorded to complete the test.

[0005] As a further improvement of the present invention, the upper side of the base is an inclined slope, and the bearing ring is clamped and fixed at an incline by the clamping structure during the test.

[0006] As a further improvement of the present invention, a sliding groove is provided in the middle of the base, a slide rail is fixed at the bottom of the groove, a slider is slidably provided on the slide rail, a probe holder is fixed on the slider, the probe is fixedly installed on the probe holder, and the positioning component consists of positioning posts respectively set on the left and right sides of the sliding groove. The two positioning posts are at the low position of the inclined surface and abut against the bearing ring to form a three-point clamping and positioning with the probe.

[0007] As a further improvement of the present invention, the probe holder includes a fixing frame and screws. The fixing frame is bent into a U-shape to form a groove structure. The probe is placed in the groove structure. The screw passes through the groove wall of the groove structure and then through the probe. After that, it is threaded to the groove wall on the other side of the groove structure to fix the probe on the probe holder.

[0008] As a further improvement of the present invention, a number of positioning holes are provided on the upper side of the base. The positioning holes are divided into two rows and are arranged in a straight line. The two rows of positioning holes are located on the left and right sides of the slide groove, respectively. One end extends to the upper side of the base near the slide groove, and the other end is inclined and away from the slide groove. The two rows of positioning holes form a V-shape with the slide groove as the center. The positioning holes near the slide groove and the positioning holes away from the slide groove gradually extend upward along the upper side of the base.

[0009] As a further improvement of the present invention, a roller is coaxially rotatably sleeved on the positioning column, and the roller surface abuts against the bearing ring.

[0010] The beneficial effects of this invention are as follows: The three-point clamping structure formed by the sliding probe and positioning components achieves stable positioning of the bearing rings, avoiding fluctuations in the probe-workpiece contact state during manual operation, and significantly improving the consistency and reliability of the magnetoelastic value detection results. The inclined base, combined with rotatable rollers, reduces the frictional resistance during bearing ring rotation, ensuring smooth workpiece rotation during testing and further reducing human interference with scanning speed. This effectively solves the technical bottlenecks of low detection efficiency and large data fluctuations in traditional manual operation. Simultaneously, the modular probe fixing structure and adjustable positioning hole design give the device good compatibility, adapting to the testing needs of bearing rings of different specifications, improving the equipment's versatility and practicality. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the device for rapid and stable testing of Barkhausen noise equipment according to the present invention. Detailed Implementation

[0012] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0013] Reference Figure 1As shown, the device for rapid and stable testing of Barkhausen noise equipment in this embodiment includes a base 1, a probe 5 slidably mounted on the base 1, and a positioning component mounted on the base 1. The probe 5 and the positioning component combine to form a clamping structure for holding the bearing race under test. During testing, the probe 5 is connected to an external device, and the probe 5 is slid to abut against the bearing race. The bearing race is clamped in the clamping structure. Then, the bearing race is manually rotated, and the magnetoelastic value MP detected by the device is recorded, completing the test. During operation, the operator only needs to slide the probe 5 to achieve stable contact with the bearing race. The three-point clamping structure ensures no workpiece displacement during testing, solving the problem of unstable probe contact state in traditional manual operation. The mechanical structure limits the consistency of the detection parameters, thereby achieving high precision and high repeatability of the magnetoelastic value detection results.

[0014] Reference Figure 1 As shown, the upper side of the base 1 is further inclined, and the bearing ring is clamped and fixed at an angle by the clamping structure during testing. The inclined design allows the gravitational component of the bearing ring to act on the positioning component, enhancing clamping stability. It also makes it easier for operators to observe the test area, solves the problem of workpieces easily falling off when placed horizontally, and further improves operational safety.

[0015] Reference Figure 1 As shown, a sliding groove is further provided in the middle of the base 1. A slide rail 2 is fixed to the bottom of the groove, and a slider 3 is slidably mounted on the slide rail 2. A probe holder 4 is fixed on the slider 3, and the probe 5 is fixedly mounted on the probe holder 4. The positioning components are positioning posts respectively set on the left and right sides of the sliding groove. The two positioning posts are at the lower position of the inclined surface and abut against the bearing ring to form a three-point clamping and positioning with the probe 5. The slide rail and slider structure realizes the linear sliding of the probe, ensuring uniform contact pressure between the probe and the workpiece. The three-point positioning design further restricts the radial movement of the workpiece, helps to solve the problem of unstable contact area, and additionally improves the structural rigidity of the device.

[0016] Reference Figure 1 As shown, the probe holder 4 further includes a fixing frame and screws 7. The fixing frame is bent into a U-shape to form a groove structure. The probe 5 is placed in the groove structure. The screw 7 passes through the groove wall and then through the probe 5, and is then threaded to the groove wall on the other side of the groove structure to fix the probe 5 to the probe holder 4. The U-shaped frame combined with the through screw fixation enables quick installation and removal of the probe and fine-tuning of the angle, solving the problem of time-consuming probe replacement with traditional clamps and further improving equipment maintenance efficiency.

[0017] Reference Figure 1As shown, furthermore, the upper side of the base 1 has several positioning holes 9, arranged in two rows in a straight line. The two rows of positioning holes 9 are located on the left and right sides of the slide groove, respectively. One end extends to the upper side of the base 1 near the slide groove, while the other end is inclined and away from the slide groove. The two rows of positioning holes 9 form a V-shape with the slide groove as the center. The positioning holes 9 near the slide groove and those away from the slide groove gradually extend upwards along the upper side of the base 1. The V-shaped positioning hole array can accommodate bearing rings of different diameters. By adjusting the installation position of the positioning pins, the clamping range can be flexibly adjusted, solving the problem of poor compatibility of traditional devices and further expanding the applicable working conditions of the equipment.

[0018] Reference Figure 1 As shown, a roller 8 is coaxially rotatably mounted on the positioning post, and the surface of the roller 8 abuts against the bearing ring. The roller structure converts sliding friction into rolling friction, reduces the resistance torque when the bearing ring rotates, solves the problem of uneven speed during manual rotation, and further improves the smoothness of the testing process.

[0019] In summary, this invention, through a three-point clamping structure consisting of a sliding probe and a positioning component, combined with an inclined base, adjustable positioning holes, and rolling support design, achieves stable clamping and smooth rotation of the bearing ring. This effectively solves the problems of large fluctuations in detection parameters and low efficiency in traditional manual operation mode, significantly improves the consistency and reliability of magnetoelastic value detection, and also has good compatibility and ease of operation, meeting the needs of high-precision quality control in modern production.
