[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Embodiment 1: This embodiment Figure 1-Figure 6 As shown, in order to solve the problem that the existing device can only clamp bearings of the same size during use, an adjustment structure is disclosed to perform a limit clamping process on bearings of different sizes, so that the device can adapt to the clamping of bearings of different sizes. The specific contents are as follows:

[0032] A mounting block 3 is fixedly mounted on the upper end of the operating table 2, and a threaded rod 4 is connected to the inner thread of the mounting block 3, and a moving part 5 is rotatably mounted on one end of the threaded rod 4 near the middle of the operating table 2;

[0033] An adjustment structure is provided inside the operating table 2, and the adjustment structure can achieve the effect of clamping bearings of different sizes by adjusting the distance between the main clamping wheel 6 and the two sets of auxiliary clamping wheels 9;

[0034] A main clamping wheel 6 and an auxiliary clamping wheel 9 are arranged inside the adjustment structure. The main clamping wheel 6 is rotatably mounted on the rear end of the moving part 5. Two groups of fixed shafts 7 are symmetrically fixedly mounted on the upper end of the operating table 2. Two groups of rotating arms 8 are rotatably mounted on the outer sides of the fixed shafts 7. The auxiliary clamping wheel 9 is rotatably mounted on the rear end of the rotating arm 8. At the same time, a driving wheel 10 is rotatably mounted on the front end of the rotating arm 8.

[0036] The centers of the main clamping wheel 6 and the two sets of auxiliary clamping wheels 9 coincide with the center of the bearing, and two sets of auxiliary clamping wheels 9 , rotating arms 8 and torsion springs 11 are arranged symmetrically about the vertical center axis of the operating platform 2 .

[0037] When using the auxiliary clamping mechanical bearing manufacturing device, first place the device at the position where work is required. After placing the device at the required position, the bearing can be manufactured and processed by the device. In this process, the bearing needs to be limited at the upper end of the operating table 2, and then the bearing can be processed. In the process of clamping and limiting the bearing, the bearing needs to be placed at the upper end of the operating table 2, and then the turntable on the outside of the threaded rod 4 needs to be rotated. At this time, the threaded rod 4 will slide inside the mounting block 3 and make the threaded rod 4 rotate at the upper end of the operating table 2, and then the moving part 5 can drive The main clamping wheel 6 moves toward the direction of the bearing, and during the movement of the moving part 5, the driving wheel 10 will drive the rotating arm 8 to rotate around the fixed axis 7. During this process, the torsion spring 11 will be wound, and during the rotation of the rotating arm 8, the auxiliary clamping wheel 9 will approach the direction of the bearing. Then, the two sets of auxiliary clamping wheels 9 and the main clamping wheel 6 will clamp the outside of the bearing. By moving two sets of auxiliary clamping wheels 9 and one set of main clamping wheels 6, bearings of different sizes can be limited and clamped, so that the device can be used for processing bearings of different sizes, thereby improving the convenience of using the device.

[0038] Embodiment 2: This embodiment is as follows Figure 3-Figure 6 As shown, in order to solve the problem that the bearing needs to be manually removed after processing, the process of the unloading structure automatically pushing the bearing off the operating table 2 is disclosed, and the effect of the device enabling the bearing to be automatically unloaded is achieved, and the specific contents are as follows:

[0039] A material unloading structure is arranged inside the operating table 2, and the material unloading structure realizes the effect of automatic unloading by automatically pushing the bearing to separate from the operating table 2;

[0040] A support member 13 is provided inside the material discharging structure, and the support member 13 is fixedly mounted on the lower end of the operating table 2;

[0043] After the device completes the bearing processing, the threaded rod 4 can be made to rotate in the opposite direction through the turntable and the moving part 5 can drive the main clamping wheel 6 to move away from the bearing. During the movement of the moving part 5, the torsion spring 11 will expand and the secondary clamping wheel 9 will move away from the bearing through the rotating arm 8. During the movement of the moving part 5, the second tooth plate 19 will be driven to move through the moving rod 18. At this time, the second tooth plate 19 will drive the rotating shaft 16 to rotate through the gear cylinder 17, and the rotation of the rotating shaft 16 will drive the third tooth plate 23 to move through another set of gear cylinders 17. During the movement of the third tooth plate 23, the push rod 21 will be driven to move inside the operating table 2 and approach the bearing. At this time, the push rod 21 will contact the bearing during its movement to push the bearing to move. At this time, the movement of the bearing will fall from the upper end of the operating table 2 due to inertia. At this point, the automatic unloading process of the device is completed, which effectively improves the convenience of using the device.

[0044] Embodiment 3: This embodiment is as follows Figure 4-Figure 6 As shown, in order to solve the problem of bearing placement displacement, the lifting and lowering working process of the limit rod 12 is disclosed, and the limit rod 12 assists in bearing clamping and material feeding, and the specific contents are as follows:

[0045] A rotating shaft 16 is rotatably installed inside the operating table 2, and a gear cylinder 17 is sleeved on the outer side of the rotating shaft 16. A limit rod 12 is slidably installed inside the operating table 2, and a connecting rod 14 is fixedly installed at the lower end of the limit rod 12, and a first gear plate 15 is fixedly installed at the lower end of the connecting rod 14.

[0046] Before rotating the turntable outside the threaded rod 4, the bearing needs to be placed on the upper end of the operating table 2. At this time, the bearing needs to be placed on the outside of the limit rod 12 to avoid rolling during the placement of the bearing, and the center point of the limit rod 12 is in the same vertical direction as the center point of the bearing. After the bearing is processed, the rotating shaft 16 and the gear cylinder 17 will rotate under the action of the third gear plate 23, and the gear cylinder 17 will also move the limit rod 12 downward and move to the inside of the operating table 2 through the connecting rod 14 and the first gear plate 15, and the upper end surface of the limit rod 12 is lower than the upper end surface of the operating table 2, so that the bearing can slide off from the upper end of the operating table 2, thereby facilitating the bearing to slide off from the upper end of the operating table 2, thereby increasing the overall practicality.

[0047] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
