Description

Technical Field

[0001] The utility model relates to the technical field of bearing detection, in particular to a mechanical parts detection workbench for motor bearings. Background Art

[0002] Motor bearings, also known as electric motor bearings or motor bearings, are special bearings used in electric motors or motors. The main function of motor bearings is to support the shaft, guide the rotation of the shaft, and bear the idling parts on the shaft. It is a key component in the operation of the motor and is essential for the smooth operation and performance of the motor.

[0003] After searching, it was found that when processing motor bearings, it is necessary to inspect the inner ring or outer ring of the bearing, such as the outer diameter size, inner diameter size, thickness, width, etc. At the same time, during the inspection, it is also necessary to fix the outside of the bearing ring and limit the top. For example, Patent No. CN208283068U discloses a workbench for bearing inspection, in which the bearing is fixed below the upper limit assembly of the rotating rod through the limit assembly on the top of the rotating rod, and the bearing is clamped and fixed between the two sets of clamping rods through the sleeve connected to the fixed ring at the bottom of the fixed rod and the clamping rod connected to the sleeve through the first spring. The bearing is firmly fixed, which is convenient for bearing inspection. When taking out the bearing, pull the bearing to pull it out from between the two sets of clamping rods, and push the adjustment button to extend the limit rod into the sleeve, so that the bearing can be quickly removed.

[0004] The above scheme can effectively fix and improve the stability of detection work, but there are still certain shortcomings. The above scheme uses spring elastic force for clamping and limiting. Although the structure is simple, the clamping stability is not perfect. At the same time, when placing and taking, it is necessary to manually overcome the elastic force of the spring, which not only increases the number of operation steps and cannot complete the clamping and limiting in one step, but also is very laborious during operation, and cannot meet the use requirements well during batch detection.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] Depend on Figure 1-Figure 7 The utility model includes a platform 1, a sleeve 15 is fixed on the top of the platform 1, a bearing sleeve body 4 is sleeved on the outside of the sleeve 15, a bidirectional screw rod 11 is rotatably connected to the bottom of the platform 1, and a sleeve block 13 is threadedly connected to both ends of the bidirectional screw rod 11. A clamping plate 14 is installed on the top of the sleeve block 13 through the platform 1. The platform 1 is provided with a limit assembly 2 on the inner side of the sleeve 15. The limit assembly 2 includes a vertical screw rod 21 rotatably connected to the top of the platform 1, and a sleeve block 22 is threadedly connected to the vertical screw rod 21. The four sides of the sleeve block 22 are fixed with inclined plane blocks A23, and the inclined plane blocks A23 fits with the inclined surface of the inclined surface block B24, and the square limit rod 26 fixed on one side of the inclined surface block B24 slides in the rod hole on the side wall of the sleeve 15, and the slider 25 of the inclined surface of the inclined surface of the inclined surface block A23 slides in the slideway of the inclined surface of the inclined surface block B24. A synchronization component 3 is connected between the vertical screw rod 21 and the bidirectional screw rod 11. The synchronization component 3 includes a bevel gear A31 and a bevel gear B32. The bevel gear A31 is fixed on the outside of the bidirectional screw rod 11, and the bevel gear B32 is rotatably connected to the bottom of the platform body 1 and docks with the bottom rotating shaft of the vertical screw rod 21. The bevel gear A31 and the bevel gear B32 are meshed with each other.

[0027] The specific operation is as follows: through the design of the bidirectional screw 11, the sleeve block 13, the clamping plate 14, the limit assembly 2 and the synchronization assembly 3, when clamping, the bearing sleeve body 4 is placed on the top of the table body 1 and sleeved on the outside of the sleeve 15, and then the bidirectional screw 11 is driven to rotate, and the two sleeve blocks 13 move together and approach each other, driving the clamping plate 14 to clamp. During this process, the bevel gear A31 will also rotate and drive the vertical screw 21 to rotate by engaging with the bevel gear B32. At this time, the sleeve block 22 drives the inclined surface block A23 to move upward, and pushes the inclined surface block B24 through the inclined surface to make the square limit rod 26 pass through the rod hole on the side wall of the sleeve 15, and the bottom surface of the square limit rod 26 is close to the top surface of the bearing sleeve body 4. At this time, the clamping plate 14 just completes the clamping. After the inspection is completed, the bidirectional screw 11 rotates in the opposite direction, and the clamping plate 14 Loosen, and the convex slider 25 will also drive the inclined surface block B24 to retreat as the inclined surface block A23 moves downward, so that the square limit rod 26 is limited, and then the bearing sleeve body 4 can be taken out. In this way, the clamping and limiting operations can be completed in one step. It is very stable, and the operation is simple, fast and labor-saving. It solves the problem that the existing design relies on spring elastic force for clamping, which is more troublesome. It should be noted that the slider 25 makes the connection between the inclined surface block A23 and the inclined surface block B24 stronger, and limits the sleeve block 22 so that it will not rotate with the vertical screw 21. At the same time, in this case, the bearing sleeve body 4 is not limited to the outer ring or the inner ring. The inner and outer rings of different specifications can use the clamping or limiting structure with corresponding parameters during detection, such as the diameter of the sleeve 15 or the specifications of the splint 14, etc.

[0028] Furthermore, the clamping plate 14 is designed with an arc surface and a rubber pad 110 is bonded to the inner side. The arc surface design of the clamping plate 14 can better fit the surface of the ring, and the rubber pad 110 can avoid scratches that may be caused by direct contact, etc., and play a protective role.

[0029] Furthermore, six evenly distributed support plates 16 are welded together on the side wall of the sleeve 15 and the top of the table body 1. Two ball grooves are provided on the top of the support plate 16, and balls 17 are rollingly connected in the ball grooves. The bearing sleeve body 4 is placed on the top of the support plate 16 and contacts with the balls 17. The support of the support plate 16 can make a gap between the bottom of the bearing sleeve body 4 and the top surface of the table body 1. Then, the bearing sleeve body 4 can be lifted from the bottom when taking it, which improves the convenience of taking it. During inspection, it may be necessary to rotate the bearing sleeve body 4 to adjust the inspection direction. At this time, the clamping can be released, and the bearing sleeve body 4 can be easily rotated by the rolling of the balls 17, which is very convenient.

[0030] Furthermore, the sleeve 15 is plugged with a dustproof plug 19 on the outside of the sliding hole through which the square limit rod 26 passes. The dustproof plug 19 is made of rubber. A circular dustproof steel plate 18 can be placed in the top opening of the sleeve 15. A buckle ring is welded on the top of the dustproof steel plate 18. After the inspection is completed, the dustproof plug 19 can be inserted into the sliding hole of the sleeve 15, and then the dustproof steel plate 18 can be covered on the top of the sleeve 15, so that the inside of the sleeve 15 is dustproof when not working, thereby preventing dust from entering the inside of the sleeve 15 and affecting various mechanical parts.

[0031] Furthermore, the bidirectional screw rod 11 is rotatably connected to two vertical plates welded at the bottom of the platform body 1, and a servo motor 12 for driving the bidirectional screw rod 11 to rotate is installed on the side wall of one of the vertical plates. In this way, when detecting the limit, the servo motor 12 can be directly started to drive the bidirectional screw rod 11 to rotate, and then the clamping limit can be completed without manual operation, thereby further improving the applicability.
