[0030] The transmission mechanism 5 includes a guide unit and a transmission unit;

[0031] The guide unit is used to provide guidance for the axial movement of the movable seat 2;

[0032] The transmission unit is used to provide transmission force for the vertical movement of the screw rod 505;

[0033] The guide unit includes a guide groove 501 and a guide block 502;

[0034] The guide groove 501 is provided at the top of the base 1 and is used to provide a moving space for the axial movement of the guide block 502;

[0035] The guide block 502 is fixed to the bottom end of the movable seat 2, and the guide block 502 is used to provide guidance for the axial movement of the movable seat 2;

[0036] The transmission unit includes a rack 503, a gear 504, a screw 505, a support block 506, and a positioning rod 507;

[0037] The rack 503 is fixed inside the guide groove 501 and is used to provide rotational thrust for the moving gear 504;

[0038] The gear 504 is rotatably mounted inside the movable base 2 and extends through the bottom of the movable base 2. The gear 504 is used to drive the screw rod 505 to move vertically.

[0039] The screw rod 505 is rotatably sleeved on the inner wall of the gear 504 and extends to the outside of the top of the movable seat 2. The screw rod 505 is used to synchronously drive the support block 506 to move;

[0040] The support block 506 is rotatably connected to the top end of the screw rod 505, and the support block 506 is used to provide support for the bearing;

[0041] The positioning rod 507 is rotatably connected to the bottom end of the support block 506 and extends to the interior of the movable seat 2. The positioning rod 507 is used to provide positioning for the vertical movement of the support block 506.

[0042] The outer wall of the detector 4 is installed with a detection rod for detecting the curvature of the bearing groove, and the clamping block 3 is slidably installed on the outer wall of the movable seat 2 through a slider and a threaded rod.

[0043] In this embodiment: when using this device, the bearing to be tested is placed between the clamping blocks 3, and the two clamping blocks 3 are driven closer to each other by rotating the threaded rod, so as to clamp the bearing. Then, the detection rod on the detector 4 is placed on the groove of the bearing, and the arc movement trajectory of the detection rod is transmitted to the detector by moving the detection rod, so as to obtain the curvature data of the bearing groove. When the test is completed, the movable seat 2 is pushed to move axially, so that the guide block 502 moves along the inner side of the guide groove 501. During the axial movement of the movable seat 2, the gear 504 connected to the bottom of the movable seat 2 will also move axially synchronously, so that the outer wall teeth of the gear 504 The block contacts the outer wall tooth block of the rack 503, and the fixed rack 503 gives the gear 504 a rotational thrust. Due to the existence of the positioning rod 507, the screw rod 505 is subjected to a reaction force and does not rotate with the rotation of the gear 504. Then the screw rod 505 will drive the support block 506 to move vertically along the inner thread groove of the gear 504, so that the support block 506 moves to the bottom of the bearing. At this time, when the two clamping blocks 3 are separated by giving the threaded rod a rotational force, the bearing loses support and falls on the upper surface of the support block 506, avoiding the bearing from falling directly, reducing the steps of manually pinching the bearing, facilitating the rapid removal of the bearing, and further improving work efficiency.

[0044] Please refer to Figure 1-Figure 3 The interior of the movable seat 2 is provided with a sliding groove for the vertical movement of the positioning rod 507, the outer side of the top end of the support block 506 matches the outer wall of the support, the outer wall tooth block of the gear 504 is engaged with the outer wall tooth block of the rack 503, and the interior of the guide groove 501 is provided with a sliding groove for the axial movement of the gear 504. The top end of the gear 504 is fixed with a sleeve for the vertical movement of the screw rod 505, and the inner side of the sleeve is formed with a thread groove that matches the outer wall thread of the screw rod 505.

[0045] In this embodiment, through this structure, during the axial movement of the movable seat 2 , the axially moving gear 504 will contact the rack 503 to rotate the gear 504 , providing a rotational thrust for the vertical movement of the screw rod 505 .

[0046] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this.
