Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bearing processing and detection, in particular to a bearing demagnetization machine for bearing processing and detection. Background Art
[0002] The bearing processing industry is rapidly developing and holds a significant market share within the machining industry. After finished bearings are processed, they typically require demagnetization. However, existing bearing demagnetization devices sometimes fail to align with the demagnetization machine or remain in the machine for too short a time, resulting in suboptimal demagnetization. Some bearings retain magnetism, but due to a lack of appropriate detection equipment to verify demagnetization results, a small number of undemagnetized bearings enter the market.
[0003] After searching, the patent document with announcement number CN220138045U discloses a bearing demagnetization device, including a workbench, the upper end of the workbench is fixedly connected to a frame, the frame is fixedly connected to a mounting rod, the lower end of the mounting rod is fixedly connected to a demagnetization box, a demagnetization coil is coaxially installed in the demagnetization box, an intermittent motion device is installed at the upper end of the workbench, and the intermittent motion device is fixedly connected to four connecting rods distributed at equal angles.
[0004] The aforementioned patent has the following drawbacks: For example, the lack of a structure to secure the bearing within the retaining ring can cause the bearing to slide or roll easily within the retaining ring, resulting in unstable position. This affects the accuracy of demagnetization and testing, as the bearing must be maintained in a specific position and posture to ensure effective demagnetization and reliable test results. Therefore, a bearing demagnetization machine for bearing processing and testing is proposed to address the aforementioned issues. Utility Model Content

[0007] An intermittent drive mechanism is provided on the upper surface of the workbench, and the intermittent drive mechanism includes a drive device fixedly mounted on the lower surface of the workbench, an intermittent gear fixedly mounted on the output shaft of the drive device, a rotating shaft rotatably mounted on the upper surface of the workbench, and a driven gear fixedly mounted on the outer surface of the rotating shaft and meshing with the intermittent gear, wherein the top end of the rotating shaft is fixed to the outer surface of the cross;
[0008] A fixed structure is provided inside the material box, and the fixed structure includes a clamp provided inside the material box and a telescopic sleeve and a telescopic rod fixedly installed between the clamp and the material box. A return spring is fixedly installed inside the telescopic sleeve, and one end of the telescopic rod away from the clamp extends to the inside of the telescopic sleeve and is fixedly connected to the other end of the return spring.
[0009] Furthermore, a mounting bracket is welded on the side wall of the workbench, and the demagnetization device is fixedly mounted on the outer surface of the mounting bracket. The demagnetization device is located above one of the material boxes.
[0010] Furthermore, the transparent detection box is hollow inside, and a transparent film is fixedly mounted on the upper surface thereof. The transparent detection box is coaxially arranged with one of the material boxes.
[0011] Furthermore, the intermittent gear is intermittently engaged with the driven gear, and the rotating shaft is connected to the workbench bearing.
[0012] Furthermore, the interior of the material box is hollow, and a cross-distributed support frame is welded to the inner side of the material box.

[0014] Furthermore, there are two fixing structures in the material box, and the two fixing structures are symmetrically arranged, and pads are fixedly installed on opposite sides of the two clamps.
[0015] Compared with the prior art, the present invention provides a bearing demagnetization machine for bearing processing and testing, which has the following beneficial effects:
[0016] 1. The bearing demagnetization machine for bearing processing and testing can prevent the bearing from shifting during rotation by setting a fixed structure for fixing the bearing in the material box, and at the same time avoid the bearing from being damaged by contact with the inner wall of the material box, thereby achieving the advantages of strong applicability and stable placement, and solving the problem of easy position shift of the bearing during rotation.
[0017] 2. The bearing demagnetization machine used for bearing processing and testing drives the cross to rotate 90 degrees through the transmission cooperation of the driving device, intermittent gear and driven gear. Every time the cross rotates, a material box corresponds to the demagnetization device and the transparent detection box. The bearing is first demagnetized by the demagnetization device and then rotates to the top of the transparent detection box. If the bearing at the detection station attracts the iron filings at the bottom of the transparent detection box and attaches them to the transparent film, the bearing demagnetization fails and the operator can screen it out. If the bearing at the detection station has no effect on the iron filings in the transparent detection box, the bearing is qualified. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] See also Figures 1 to 4 A bearing demagnetization machine for bearing processing and inspection includes a workbench 1 and a demagnetization device 3 arranged above the workbench 1. A cross 4 is provided on the upper surface of the workbench 1, and a material box 5 is fixedly installed at one end away from the cross 4, and a transparent detection box 10 is installed on the upper surface of the workbench 1 and is located below one of the material boxes 5; a mounting frame 2 is welded on the side wall of the workbench 1, and the demagnetization device 3 is fixedly installed on the outer surface of the mounting frame 2, and the demagnetization device 3 is located above one of the material boxes 5.
[0025] Among them, the outer surface of the workbench 1 is welded with supporting legs.
[0026] Specifically, the transparent inspection box 10 is hollow, with a transparent film 11 fixedly mounted on its upper surface. The transparent inspection box 10 is coaxially arranged with one of the material boxes 5. After being demagnetized by the demagnetization device 3, the bearing rotates to the top of the transparent inspection box 10. If the bearing in the inspection station attracts iron filings at the bottom of the transparent inspection box 10 and adheres them to the transparent film 11, the demagnetization test fails and the operator can screen it out. If the bearing in the inspection station does not affect the iron filings in the transparent inspection box 10, the bearing passes.
[0027] In this embodiment, an intermittent drive mechanism is provided on the upper surface of the workbench 1. The intermittent drive mechanism includes a drive device 6 fixedly mounted on the lower surface of the workbench 1, an intermittent gear 7 fixedly mounted on the output shaft of the drive device 6, a rotating shaft 8 rotatably mounted on the upper surface of the workbench 1, and a driven gear 9 fixedly mounted on the outer surface of the rotating shaft 8 and meshing with the intermittent gear 7. The top of the rotating shaft 8 is fixed to the outer surface of the cross 4; the intermittent gear 7 intermittently meshes with the driven gear 9, and the rotating shaft 8 is connected to the bearing of the workbench 1. The cross 4 is driven to rotate 90 degrees through the transmission cooperation of the drive device 6, the intermittent gear 7, and the driven gear 9. Every time the cross 4 rotates once, a material box 5 corresponds to the demagnetization device 3 and the transparent detection box 10. The bearing is first demagnetized by the demagnetization device 3 and then rotates to the top of the transparent detection box 10 for detection.
[0028] In this embodiment, a fixed structure is provided inside the material box 5, and the fixed structure includes a clamp 13 provided inside the material box 5 and a telescopic sleeve 14 and a telescopic rod 15 fixedly installed between the clamp 13 and the material box 5. A return spring 16 is fixedly installed inside the telescopic sleeve 14, and the telescopic rod 15 extends from one end of the clamp 13 to the inside of the telescopic sleeve 14 and is fixedly connected to the other end of the return spring 16.
[0029] Specifically, the inside of the magazine 5 is hollow, and a cross-shaped support frame 12 is welded to the inside of the magazine 5. There are two fixed structures in the magazine 5, and the two fixed structures are symmetrically arranged. The two clamps 13 are fixedly installed with protective pads 18 on the opposite sides to protect the outer surface of the bearing.
[0030] Both telescopic sleeve 14 and telescopic rod 15 have positioning holes, into which positioning shaft 17 is inserted. The clamp 13 secures the bearing by the expansion and contraction of telescopic sleeve 14 and telescopic rod 15, coupled with the deformation of return spring 16. Once the bearing is secured, positioning shaft 17 is inserted into the positioning hole to further secure the bearing.
[0031] The working principle of the above embodiment is:
[0032] During use, the bearing to be tested is placed in the material box 5, and the clamp 13 is used to fix the bearing through the telescopic cooperation of the telescopic sleeve 14 and the telescopic rod 15 and the deformation of the reset spring 16. After the bearing is fixed, the positioning shaft 17 is inserted into the positioning hole to strengthen the fixation of the bearing, and then the cross 4 is driven to rotate ninety degrees through the transmission cooperation of the driving device 6, the intermittent gear 7 and the driven gear 9. Every time the cross 4 rotates once, there is a material box 5 corresponding to the demagnetization device 3 and the transparent detection box 10. The bearing is first demagnetized by the demagnetization device 3 and then rotates to the top of the transparent detection box 10. If the bearing at the detection position attracts the iron filings at the bottom of the transparent detection box 10 and attaches them to the transparent film 11, the bearing demagnetization is unqualified and the operator can screen it out. If the bearing at the detection position has no effect on the iron filings in the transparent detection box 10, the bearing is qualified.
[0033] The installation method, connection method or setting method disclosed in this embodiment are all common mechanical connection methods, and can be implemented as long as they can achieve their beneficial effects. In addition, the electrical components appearing in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Technicians in this field can control the electrical components through simple programming, and the existing disclosed power connection technology is also common knowledge in this field, so the specific structural composition and working principle will not be described in detail in this embodiment.
