[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] The present embodiment provides a mechanical bearing stiffness test tool, which is used to detect the planar stiffness of the mechanical bearing after the mechanical bearing is produced. Through the cooperation between the support table 1, the placement guide groove 2, the load-bearing long groove 3, the propulsion mechanism 4, the limit mechanism 6, the bearing stiffness tester 7, the guide inclined groove 8 and the storage groove 9, the continuous detection of the stiffness of the mechanical bearing body 5 can be achieved, avoiding the trouble of workers needing to place the mechanical bearing bodies 5 one by one for detection, thereby improving the efficiency of the stiffness detection of the mechanical bearing body 5, and further saving the workers' physical strength and time.

[0023] See also Figure 1 to Figure 4 A mechanical bearing stiffness test tool comprises a support table 1 and a group of mechanical bearing bodies 5. A placement guide groove 2 is provided on the upper surface of the support table 1. By using the provided placement guide groove 2, the mechanical bearing body 5 can be guided. A guide inclined groove 8 is provided inside the support table 1. A storage groove 9 is installed on the left side of the support table 1. By using the provided guide inclined groove 8, the mechanical bearing body 5 can be better placed inside the storage groove 9.

[0024] The outer surface of the support table 1 is fixedly connected with a load-bearing long groove 3, the inner bottom wall of the load-bearing long groove 3 is flush with the inner bottom wall of the placement guide groove 2, and a group of mechanical bearing bodies 5 are placed on the inner bottom walls of the placement guide groove 2 and the load-bearing long groove 3 in sequence, so that the mechanical bearing body 5 on the load-bearing long groove 3 can be moved to the top of the placement guide groove 2.

[0025] A propulsion mechanism 4 is arranged inside the bearing long slot 3, and the propulsion mechanism 4 includes a first stepper motor 401 and a push plate 403. The first stepper motor 401 is a stepper motor with forward and reverse rotation functions. Each time the threaded rod 402 is driven to rotate once, the push plate 403 can move the distance of a mechanical bearing body 5. This is an existing mature technology.

[0026] The output end of the first stepper motor 401 is fixedly connected to a threaded rod 402, the outer surface of the threaded rod 402 is threadedly connected to the inner wall of the push plate 403, and the side of the push plate 403 close to the rightmost mechanical bearing body 5 is in contact with the outer surface of the mechanical bearing body 5, and the outer surface of the push plate 403 is in contact with the inner wall of the bearing long groove 3. The inner bottom wall of the bearing long groove 3 is provided with a groove that allows the push plate 403 to pass through, so that the threaded rod 402 can drive the push plate 403 to move.

[0027] The outer surface of the first stepper motor 401 is fixedly connected to the first motor base 404, and the upper surface of the first motor base 404 is fixedly connected to the bottom surface of the support table 1. By using the set first motor base 404, the first stepper motor 401 can be supported.

[0028] A limiting mechanism 6 is arranged inside the support table 1, and the limiting mechanism 6 includes a second stepper motor 601. A bidirectional screw rod 602 is fixedly connected to the output end of the second stepper motor 601. Two symmetrical driving blocks 603 are threadedly connected to the outer surface of the bidirectional screw rod 602. The outer surfaces of the two driving blocks 603 are both slidably connected to the inner wall of the support table 1. By starting the second stepper motor 601, the bidirectional screw rod 602 can be driven to rotate, and the two driving blocks 603 can be driven to move in a direction close to each other.

[0029] The upper surfaces of the two driving blocks 603 are fixedly connected with driving plates 604, and the side surfaces of the two driving plates 604 close to each other are fixedly connected with rubber pads 605. The second stepper motor 601 is a stepper motor with forward and reverse rotation functions. Forward rotation can enable the two driving plates 604 to limit the mechanical bearing body 5, and reverse rotation can enable the two driving plates 604 to release the limit on the mechanical bearing body 5.

[0032] Working principle: When the stiffness of the mechanical bearing body 5 needs to be tested, each mechanical bearing body 5 is placed one by one on the inner bottom wall of the bearing slot 3, and then the first stepper motor 401 is started, which can drive the threaded rod 402 to rotate, and then the push plate 403 can be driven to move, so that the push plate 403 can push a group of mechanical bearing bodies 5 to move, and the leftmost mechanical bearing body 5 can be moved to the top of the placement guide slot 2. By starting the second stepper motor 601, the bidirectional screw rod 602 can be driven to rotate, and the two driving blocks 603 can be driven to move in a direction close to each other, so that the two driving plates 604 can drive the two rubber pads 605 to clamp the mechanical bearing body 5, and then the bearing stiffness tester 7 can be started to test the mechanical bearing body 5. After the detection is completed, start the second stepper motor 601 to drive the bidirectional screw rod 602 to rotate in the opposite direction, so that the two driving blocks 603, the driving plate 604 and the rubber pad 605 can move away from each other, so that the rubber pad 605 can release the limit on the mechanical bearing body 5, and then start the first stepper motor 401, which can drive the push plate 403 to push the rightmost mechanical bearing body 5 to move, and the rear mechanical bearing body 5 moves to the top of the guide groove 2, and can push the frontmost mechanical bearing body 5 through the guide inclined groove 8 into the inside of the storage groove 9, and then start the second stepper motor 601 to clamp the next mechanical bearing body 5 for detection, and repeat the cycle to achieve continuous detection of the mechanical bearing body 5.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
