Description

Technical Field

[0001] The utility model belongs to the technical field of radial clearance detection and relates to an online detection mechanism for radial clearance in deep groove ball bearing machining. Background Art

[0002] The bearing clearance is the amount of movement when the inner ring or outer ring of the bearing is fixed when it is not installed on the shaft or bearing box, and then the unfixed side is moved radially or axially. According to the direction of movement, it can be divided into radial clearance and axial clearance. The measurement of the radial clearance of the bearing is to fix the inner ring or outer ring, apply a measuring load that can obtain a stable measurement value to the unfixed ring, and make reciprocating movements in the diameter direction for measurement. Place the probe in the middle of the width of the unfixed ring, read the movement of the ring in the load direction at each angular position (at least three evenly distributed), and the arithmetic mean (minus the increase caused by the measured load) is the bearing radial clearance value.

[0003] When the existing equipment performs radial clearance detection, the bearings are moved along the slide to the loading part in sequence. The loading part pops out the bearings into the base on the upper side at intervals, and then the electric telescopic rod pushes the base to the bottom of the clearance detector for detection. However, when the next undetected bearing pushes the detection to complete the bearing movement, the subsequent bearings may fall from the loading part due to the vibration of the equipment during this material replacement process. At the same time, when the electric telescopic rod pushes the base to move to the clearance detector, it may cause the bearing here to move into the right slide, thereby resulting in missed detection.

There is a table top 34, on which an electric telescopic rod 22 is installed. The extended end of the electric telescopic rod 22 is covered with a spring 4. At the same time, a base 41 is installed at one end of the electric telescopic rod 22. A feeding component 5 is provided on one side of the base 41.

An upper gear rod 72 and a lower gear rod 73 are respectively inserted in the side rod 71. Fastening bolts 8 are installed on the ring 7 and the side rod 71.

[0027] In this embodiment, the clearance detector 11 is a device for measuring the bearing clearance. The radial clearance of the bearing is the gap between the bearing rolling element and the inner and outer ring housings of the bearing. The size of the clearance during operation affects the rolling fatigue life, temperature rise, noise, vibration and other performances of the bearing. The loading component 5 is responsible for lifting the bearing upward in the radial clearance detection line 12. The loading component 5 is located on the upper side of the left slide 21. The bearing slides along the left slide 21 into the loading component 5, and then the electric telescopic rod 22 pushes the previous bearing to let it fall into the base 41.

[0028] Combination Figure 1 , Figure 2 As shown, the clearance detector 11 is suspended above the operating table 1, and the right slide 2, the left slide 21 and the base 41 are located on the same horizontal line.

[0029] Further, in the initial state, the right slide 2 and the left slide 21 and the base 41 are located at the same horizontal line. In this way, the bearing can be moved along the left slide 21 to the base 41, and the bearing that has been tested can be moved along the base 41 to the right slide 2 in the subsequent process.

[0030] Combination Figure 1 , Figure 2As shown, the support legs 31 are symmetrically arranged, the cross beams 32 are symmetrically arranged on the support legs 31, and the table top 34 has the same height as the support legs 31. The other end of the spring 4 is fixedly connected to the base 41, and the base 41 is provided with two bottom plates at intervals, and the bottom of the base 41 is provided with an arc-shaped groove.

[0031] Furthermore, the electric telescopic rod 22 pushes the base 41 equipped with the bearing to the bottom of the clearance detector 11. The bottom of the base plate arranged at intervals in the base 41 is installed with an arc-shaped groove, and the bearing can be seated in the groove, which can avoid the problem of the bearing falling off to a certain extent and facilitate maintaining the balance of the bearing.

[0032] Combination Figure 1 , Figure 2 As shown, the bottom of the base 41 is seated on the cross beam 32, and a slider is symmetrically arranged on the lower outer wall of the base 41, and the base 41 is slidably connected to the slide rail 33 through the slider. The fixed block 61 is fixedly connected to the cross beam 32, and the bottom of the rectangular rod 62 is installed with an electric telescopic rod 22, and the electric telescopic rod 22 is seated on the operating table 1.

[0033] Furthermore, the electric telescopic rod 22 on the table 34 pushes the base 41, so that the base 41 moves along the slide rail 33 through the slider at the bottom to the lower side of the clearance detector 11 for detection.

[0034] Combination Figure 1 , Figure 4 As shown, the rectangular rod 62 is slidably connected to the fixed block 61, the collar 7 is slidably connected to the rectangular rod 62, and the collar 7 is respectively located at the upper and lower sides of the fixed block 61. The side rod 71 extends to the left slide 21, the upper gear rod 72 and the lower gear rod 73 are bent, the upper gear rod 72 is located at the upper side of the left slide 21, and the lower gear rod 73 is located at the lower side of the left slide 21.

[0035] Furthermore, the rectangular rod 62 can slide along the fixed block 61, so that the lower electric telescopic rod 22 can push the rectangular rod 62 to move. At the same time, the upper gear rod 72 and the lower gear rod 73 are located on the upper small side of the left slide 21, and the upper gear rod 72 and the lower gear rod 73 are installed by staggered installation to limit the two sides of the base 41.

[0036] Combination Figure 1 , Figure 4 As shown, the upper lever 72 is inserted into the area between the base 41 and the loading component 5 , and the lower lever 73 is inserted into the area between the base 41 and the left slide 21 .

[0037] Furthermore, the bent portion of the upper lever 72 faces the area between the base 41 and the loading component 5, and the lower lever 73 passes through the bracket 3, and the bent portion of the lower lever 73 faces the area between the base 41 and the right slide 2.

[0038] Combination Figure 1 , Figure 4 As shown, the vertical spacing between the bent portions of the upper gear rod 72 and the lower gear rod 73 is greater than the size of the base 41 .

[0039] Furthermore, the fastening bolts 8 are located at the points where the upper gear rod 72 and the lower gear rod 73 penetrate the side rod 71 and at the point where the collar 7 penetrates the rectangular rod 62. The positions of the above three can be adjusted by fastening the bolts 8 and play a fixing role. When the bent parts of the upper gear rod 72 and the lower gear rod 73 are located on the upper and lower sides of the right slide 2, the electric telescopic rod 22 pushes the undetected bearing to advance the previously detected bearing into the right slide 2.

[0040] The working principle of the utility model is:

[0041] The electric telescopic rod 22 pushes the rectangular rod 62 to adjust the positions of the upper gear rod 72 and the lower gear rod 73 so that neither the upper gear rod 72 nor the lower gear rod 73 blocks the base 41. The bearing moves along the left slide 21 to the loading component 5, and then the loading component 5 pushes the bearing inside it upward to the same height as the base 41. Then the electric telescopic rod 22 on the left pushes the undetected bearing to the right, and the undetected bearing presses against the detected bearing to push it into the right slide 2.

[0042] When the new bearing falls into the base 41, the electric telescopic rod 22 first pushes the rectangular rod 62 upward to move it along the fixed block 61. When the upper gear rod 72 moves above the base 41, the lower gear rod 73 blocks the right side outlet of the base 41 to prevent the bearing here from moving along the base 41 into the right slide 2.

[0043] Then the electric telescopic rod 22 pulls the rectangular rod 62 downward, allowing the upper gear rod 72 to block the loading part 5 to prevent the bearings that are not tested later from shaking due to external reasons and falling out of it. The electric telescopic rod 22 on the table 34 pushes the base 41 to move it to the bottom of the clearance detection machine 11 for detection, and moves it to the initial position after the detection is completed.

[0044] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways without departing from the spirit of the present invention.
