Description

In the hollow cavity of the rotating table 43, a clamping assembly for clamping the outer ring of the bearing is also arranged on the hollow rotating table 43, and the clamping assembly includes a groove 44. Four grooves 44 are equidistantly arranged on the side wall of the hollow cavity of the hollow rotating table 43 in the circumferential direction. A gear 45 is rotatably connected in the groove 44.

A follower rack 411 is also slidably arranged in the groove 44. The follower rack 411 is located above the gear 45. The follower rack 411 is meshed with the gear 45. A connecting column 412 is fixedly connected to the top of the follower rack 411. The end of the connecting column 412 away from the follower rack 411 extends to the top of the hollow rotating table 43 and is fixedly connected to an arc-shaped clamping plate. A rubber pad is arranged on the side of the arc-shaped clamping plate close to the truncated table 35. The arc-shaped clamping plate is used to clamp and fix the outer ring of the bearing.

[0019] When working: Initial definition: the electric telescopic rod 32 is preset with an extended length through the controller, and the telescopic end of the electric telescopic rod 32 is in an extended state.

[0020] This device can detect the load-bearing strength of a single bearing, using pressure sensors and vibration sensors to detect the load-bearing capacity and strength of the outer ring of the bearing in a rotating state; This device can fix the inner ring of the bearing before testing the bearing. The detailed steps are as follows: The staff makes the connecting plate 311 pass through the inner ring of the bearing and places the inner ring of the bearing on the upper surface of the T-shaped cavity rod 34. At this time, the outer ring of the bearing does not contact the upper surface of the T-shaped cavity rod 34, and the outer ring of the bearing is located above the hollow rotating table 43. Then, the electric telescopic rod 32 is started to make the telescopic end of the electric telescopic rod 32 contract. During the contraction of the telescopic end of the electric telescopic rod 32, the follower plate 33 moves vertically downward along the telescopic end of the electric telescopic rod 32 toward the base 31, so that the follower plate 33 drives the T-shaped cavity rod 34 to move vertically downward along the guide column 37 toward the base 31, until the telescopic end of the electric telescopic rod 32 completes the contraction of the preset length. At this time, the bottom of the hollow rotating table 43 contacts and presses down the contact switch 3701, so that the electromagnet in the cavity block 410 is in the on state.

[0021] During the vertical downward movement of the T-shaped cavity rod 34 along the guide column 37, after the fixed rod 38 contacts the trigger column 313, as the T-shaped cavity rod 34 continues to move downward, the trigger column 313 moves vertically upward along the slide groove 314 relative to the T-shaped cavity rod 34. During this process, the spring 1 316 is gradually stretched, and the trigger column 313 pushes the connecting plate 311 and the connecting rod 310 to rotate, so that the connecting rod 310 rotates in a direction away from the axis of the T-shaped cavity rod 34 with the rotating connection with the fixed column 39 as the axis, further causing the downward pressure column 312 to press downward on the top of the inner ring of the bearing, thereby fixing the inner ring of the bearing.

[0022] In the above steps, the downward pressure column 312 is rotated to press down the surface of the inner ring of the bearing, thereby achieving the effect of fixing the inner ring of the bearing. Compared with the manual fixing method using bolts in the prior art, after placing the bearing, the device can fix the inner ring of the bearing by controlling the telescopic end of the electric telescopic rod 32 to shrink to a preset length, eliminating the step of manually fixing with bolts, speeding up the process of loading and unloading the bearing, and being more efficient. In addition, automatically pressing down to fix the inner ring of the bearing can ensure that the fixing force applied each time is consistent, avoiding uneven fixing force caused by manual operation, resulting in loosening of the bearing during load-bearing strength testing in a rotating state, causing a decrease in the balance of the bearing during the load-bearing strength test, thereby affecting the test result. In this way, the stability of the bearing test stress state is ensured.

[0023] This device can clamp the outer ring of the bearing before testing the bearing. The detailed steps are as follows: Since the truncated cone 35 is wide at the top and narrow at the bottom, when the T-shaped cavity rod 34 and the truncated cone 35 move vertically downward, the truncated cone 35 will squeeze the roller 47 and the rack plate 46, and make the roller 47 and the rack plate 46 move horizontally in the direction away from the side of the truncated cone 35 until the T-shaped cavity rod 34 stops moving downward. During this process, the spring 49 is gradually compressed, the gear 45 rotates, and the gear 45 drives the follower rack 411 and the connecting column 412 to move horizontally in the direction close to the side of the truncated cone 35. The outer ring of the bearing is clamped and fixed by four arc-shaped clamping plates. When the T-shaped cavity rod 34 continues to move downward, the connecting column 412 drives the arc-shaped clamping plate to further squeeze the outer ring of the bearing and The rubber pad on the arc-shaped clamping plate is squeezed, and the downward pressure column 312 also presses down the surface of the inner ring of the bearing. When the T-shaped cavity rod 34 stops moving downward, the bottom of the T-shaped cavity rod 34 presses the contact switch 3701, so that the electromagnet in the cavity block 410 is in the starting state, thereby generating suction on the magnetic suction rod 48, so that the rack plate 46 continues to move horizontally toward the side close to the cavity block 410, and at the same time, the connecting column 412 further squeezes the rubber pad on the arc-shaped clamping plate until the magnetic suction rod 48 contacts the electromagnet inside the cavity block 410. At this time, the roller 47 no longer contacts the frustum 35, and the arc-shaped clamping plate on the connecting column 412 completes the clamping and fixing of the outer ring of the bearing.

[0024] Then, the annular weight plate is placed on the upper surface of the outer ring of the bearing by using the robotic arm 2, and the outer ring of the bearing is pressed down, and the size of the load is detected by using a pressure sensor. Then, the staff starts the servo motor arranged inside the support platform 1, so that the output shaft of the servo motor rotates, driving the driving gear 41 to rotate, and the driving gear 41 drives the hollow rotating platform 43 to rotate, thereby driving the outer ring of the bearing, the weight plate and the robotic arm 2 to rotate, and cooperates with the vibration sensor for detection. By analyzing whether there are abnormalities in the vibration amplitude and frequency of the bearing during rotation, it is determined whether the bearing is deformed or damaged, and then the detection data is displayed on the display, thereby completing the load-bearing strength detection under the rotating state of the bearing.

[0025] When the test is completed, the staff turns off the servo motor and uses the mechanical arm 2 to separate the weight plate from the outer ring of the bearing. Then the staff starts the electric telescopic rod 32 to extend the telescopic end of the electric telescopic rod 32. During the extension of the telescopic end of the electric telescopic rod 32, the follower plate 33 moves vertically upward along the telescopic end of the electric telescopic rod 32 in a direction away from the base 31, so that the follower plate 33 drives the T-shaped cavity rod 34 to move vertically upward along the guide column 37 in a direction away from the base 31. When the T-shaped cavity rod 34 moves vertically upward, the T-shaped cavity rod 34 moves vertically upward. The bottom of the cavity rod 34 disengages from the contact switch 3701, causing the electromagnet inside the cavity block 410 to become closed. At this time, the spring 2 49 rebounds and resets, causing the roller 47 to re-contact the outer surface of the table 35. As the T-shaped cavity rod 34 continues to move upward, the rack plate 46 moves horizontally toward the side close to the table 35, and the follower rack 411 and the connecting column 412 move horizontally toward the side away from the table 35, until the T-shaped cavity rod 34 stops moving upward, and the rack plate 46, the follower rack 411 and the connecting column 412 return to their initial positions.

[0026] While the T-shaped cavity rod 34 moves vertically upward, spring 1 316 rebounds and resets, causing the trigger column 313 to move vertically downward along the slide groove 314 relative to the T-shaped cavity rod 34. During this process, the trigger column 313 pulls the connecting plate 311 and the connecting rod 310 to rotate, causing the connecting rod 310 to rotate in the direction close to the axis of the T-shaped cavity rod 34 around the rotating connection with the fixed column 39 until the connecting plate 311 and the downward pressure column 312 rotate back to their initial positions, so as to remove the tested bearing and facilitate the detection of the next bearing.

[0027] Embodiment 2 of the present invention:

[0028] like Figure 1 , Fig.12 and Fig.13 As shown, a cooling component is provided on the hollow rotating table 43, and the cooling component includes a piston cylinder 51 fixedly connected to the upper surface of the hollow rotating table 43. There are four piston cylinders 51, and the four piston cylinders 51 are respectively arranged corresponding to the positions of the four connecting columns 412. A piston plate is slidably connected in the piston cylinder 51, and the piston plate of the piston cylinder 51 is fixedly connected to the adjacent connecting column 412. The piston cylinder 51 is connected with a one-way air inlet pipe 52 and a one-way air outlet pipe 53. The one end of the one-way air outlet pipe 53 away from the piston cylinder 51 is connected with a cavity plate 54, and the cavity plate 54 is fixedly connected to the upper surface of the hollow rotating table 43. An air outlet is provided on the side of the cavity plate 54 away from the one-way air outlet pipe 53, and the air outlet faces the connecting plate 311. Air enters the interior of the piston cylinder 51 through the one-way air inlet pipe 52, and then enters the interior of the cavity plate 54 through the one-way air outlet pipe 53, so that the gas ejected from the air outlet can act on the outer ring of the bearing.

[0029] Furthermore, the shape of the cavity plate 54 is arc-shaped, and the four cavity plates 54 are arranged equidistantly in the circumferential direction.

[0030] This device can cool down the bearing after testing, making it easier for the staff to replace the bearing. The detailed steps are as follows: Before the bearing is inspected, when the connecting column 412 moves horizontally toward the side close to the truncated cone 35, the connecting column 412 pulls the piston plate in the piston cylinder 51, so that the air is sucked into the interior of the piston cylinder 51 through the one-way air inlet pipe 52. After the bearing is inspected, when the connecting column 412 moves horizontally toward the side away from the truncated cone 35, the connecting column 412 pushes the piston plate of the piston cylinder 51, so that the gas in the piston cylinder 51 enters the cavity plate 54 from the one-way air outlet pipe 53, and is ejected from the air outlet provided in the cavity plate 54 toward the bearing outer ring, thereby achieving the purpose of cooling the bearing outer ring after inspection; In the above steps, the piston plate in the piston cylinder 51 is pushed when the connecting column 412 returns to the initial position, so that the gas in the piston cylinder 51 is ejected from the cavity plate 54 and sprayed toward the outer ring of the bearing, thereby cooling the bearing after the load-bearing strength test. Compared with the natural cooling method adopted in the prior art, the present device sprays air toward the outer ring of the bearing through four arc-shaped cavity plates 54 after the test, so that the temperature of the outer ring of the bearing is effectively reduced, which is convenient for the staff to replace the bearings, thereby reducing the cooling time of each bearing, thereby improving the overall work efficiency.

[0031] The above descriptions are merely embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
