Description

Technical Field

[0001] The utility model belongs to the field of correction equipment, and in particular relates to a correction device for improving the assembly accuracy of a bearing outer ring. Background Art

[0002] The outer ring of the bearing is a component of the rolling bearing, usually a metal ring, located between the inner ring of the bearing and the shaft, which plays the role of supporting and fixing the shaft. If the assembly accuracy of the outer ring of the bearing is not high, it will cause the shaft to run unstably, generate noise and vibration, and even affect the normal operation of the equipment.

[0003] Therefore, in order to ensure the stable operation of the shaft, the outer ring of the bearing needs to be corrected to improve its assembly accuracy. The purpose of the correction is to adjust the position and angle of the outer ring of the bearing so that it can accurately match the inner ring and the shaft to reduce friction and vibration during operation. However, in actual use, the correction device has the problem that the correction component cannot be adjusted according to the diameter of the outer ring of the bearing. This is because there is a lack of a correction component position adjustment component. The lack of a correction component position adjustment component will not only lead to the above problems, but may also affect assembly efficiency and accuracy, because it is impossible to accurately calibrate the specific diameter of each bearing outer ring, which may lead to inconsistent accuracy of the outer ring of the bearing after assembly, thereby affecting the overall performance and reliability of the equipment. Therefore, it is necessary to propose a new structure to solve the above technical problems. Utility Model Content

[0022] See also Figure 1 , Figure 2 As the first embodiment of the utility model: a support leg 110 is respectively installed at the four corners of the lower surface of the base 100, a driving motor 130 is installed at the center of the front surface and the rear surface of the base 100, the output shaft of the driving motor 130 is connected to the threaded section, and the front end and the rear end of the outer surface of the threaded section are respectively arranged in a forward thread and a reverse thread;

[0023] The outer surface of the forward thread segment of the thread segment is connected to the clamping plate 120 on the front side of the upper surface of the base 100, and the outer surface of the reverse thread segment of the thread segment is connected to the clamping plate 120 on the rear side of the upper surface of the base 100. The two clamping plates 120 have the same structure and are symmetrically arranged.

[0024] When in use, the user first starts the drive motor 130, so that the output shaft of the drive motor 130 rotates to drive the threaded section to rotate (the output shaft rotates in the opposite direction), so that the two clamps 120 move away from each other on the upper surface of the base 100. After the two clamps 120 are opened to the maximum distance, the user can place the outer ring of the bearing that needs to be calibrated on the upper surface of the base 100 (the maximum diameter of the outer ring of the placed bearing must not be greater than the maximum distance between the two clamps 120). After the placement is completed, the drive motor 130 is started again according to the above steps to make the drive motor 130 move. The output shaft rotates in the forward direction, causing the two clamps 120 to move towards each other, thereby clamping and fixing the outer ring of the bearing placed on the upper surface of the base 100. Next, the correction operation can be performed through the correction assembly 300 in combination with the slide assembly. The base 100 and the clamp 120 in the clamping assembly can provide stable support and clamping to ensure that the outer ring of the bearing will not move or shake during the assembly process, thereby improving the accuracy and stability of the assembly. At the same time, the introduction of the drive motor 130 makes the correction device have a certain degree of automation, which can quickly and accurately clamp and adjust the outer ring of the bearing, thereby improving the assembly efficiency.

[0025] See also Figure 1 , Figure 2 As the second embodiment of the utility model: a mounting plate 200 is symmetrically mounted on the left and right surfaces of the base 100, the two mounting plates 200 have the same structure, a slide groove 210 is opened at the center of the upper surface of the two mounting plates 200, and a slider 220 is slidably mounted inside the two slide grooves 210;

[0026] The upper surface of the slider 220 is fixed with a bottom plate 310 by screws, a threaded column 320 is installed at the center of the upper surface of the bottom plate 310, a threaded knob 331 is threadedly connected to the outer surface of the threaded column 320, and a sliding member 330 is installed above the threaded knob 331 through the threaded column 320;

[0028] There are two groups of correction components 300, the two groups of correction components 300 have the same structure and are symmetrically arranged with each other through the slide plate assembly;

[0029] When in use, after the clamping assembly clamps and fixes the outer ring of the bearing, the user can move the correction assembly 300 on the left and right surfaces of the clamping assembly to the top of the outer ring of the bearing through the slider 220 according to the diameter of the outer ring of the bearing. After the correction assembly 300 is adjusted along the slide groove 210 by the slider 220, the user can adjust the position of the sliding member 330 along the threaded column 320 by turning the threaded knob 331, so that the user can make a preliminary position adjustment to the correction column 340 through the sliding member 330. After the adjustment of the sliding member 330 is completed, the user can pinch the hand knob 341 to adjust the hand knob 331. 41 drives the correction column 340 to move up and down, and then the lower end of the correction column 340 abuts against the upper surface of the outer ring of the bearing, thereby completing the correction. Since the correction column 340 abuts against the surface of the outer ring of the bearing, it can directly act on the outer ring to achieve precise correction. At the same time, the upper and lower external positions of the correction column 340 are roughly adjusted by adjusting the upper and lower positions of the sliding member 330.
