[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a new technical solution: a strength testing device for deep groove ball bearings, including a testing table 1, a U-shaped frame 2 fixedly installed on the upper surface of the testing table 1, a first hydraulic cylinder 3 fixedly installed on the upper surface of the U-shaped frame 2, the lower end of the first hydraulic cylinder 3 rotatably penetrating to the lower side of the U-shaped frame 2, and a pressure plate 4 fixedly installed on the telescopic end of the first hydraulic cylinder 3.

[0024] An auxiliary mechanism is installed on the testing table 1. The auxiliary mechanism includes a mounting block 5 and two semi-circular plates 6. The upper surface of the testing table 1 has a mounting groove 7. The mounting block 5 is slidably inserted into the mounting groove 7. The upper surface of the mounting block 5 has a rectangular groove 8. Two rectangular plates 9 are slidably installed inside the rectangular groove 8. The two semi-circular plates 6 are respectively fixedly installed on the upper ends of the two rectangular plates 9. A second hydraulic cylinder 10 is fixedly installed on the lower surface of the testing table 1. The telescopic end of the second hydraulic cylinder 10 slides through into the mounting groove 7 and contacts the lower surface of the mounting block 5.

[0025] Furthermore, the auxiliary mechanism also includes two bolts 11. Circular grooves 12 are provided at both ends of the mounting block 5. The two bolts 11 are threaded onto the inner walls of the two circular grooves 12 respectively. The near ends of the two bolts 11 are threaded through into the interior of the rectangular groove 8. The two bolts 11 are rotatably connected to the two rectangular plates 9 respectively.

[0026] Furthermore, by automatically lifting the mounting block 5 with the second hydraulic cylinder 10, when the deep groove ball bearing needs to be removed, the mounting block 5 can be removed directly along with the deep groove ball bearing. This prevents secondary damage to the deep groove ball bearing when using a clamp to remove it, which would affect subsequent measurement data and reduce the possibility of data deviation caused by other factors. This improves the accuracy of the equipment in testing the strength of the deep groove ball bearing.

[0027] Furthermore, convex circular grooves 13 are provided on the distant surfaces of the two rectangular plates 9, and convex circular rods 14 are rotatably installed inside the two convex circular grooves 13. The two convex circular rods 14 are respectively fixedly connected to two bolts 11.

[0028] Furthermore, a third hydraulic cylinder 15 is fixedly installed on both the left and right surfaces of the U-shaped frame 2, and the telescopic ends of the two third hydraulic cylinders 15 slide through into the interior of the U-shaped frame 2.

[0029] Furthermore, U-shaped protective plates 16 are fixedly installed on the telescopic ends of both third hydraulic cylinders 15.

[0030] Furthermore, grooves 17 are provided on the upper ends of both the left and right surfaces of the mounting block 5.

[0031] Furthermore, when using this equipment to perform strength testing on deep groove ball bearings, the deep groove ball bearing can be placed on two semi-circular plates 6, and the two bolts 11 can be rotated to move the two semi-circular plates 6 away from each other to fix the bearing. Then, the two third hydraulic cylinders 15 and their U-shaped protective plates 16 at their telescopic ends are activated to bring them closer together, pressing down the pressure plate 4 to enclose the position where it contacts the deep groove ball bearing. This can protect the operator during the testing process. After the strength test of the deep groove ball bearing is completed, the testing equipment is in a stopped state, and all components are in their initial positions. The second hydraulic cylinder 10 is activated, and the telescopic end of the second hydraulic cylinder 10 extends upward, slides through into the interior of the mounting groove 7, and contacts the lower surface of the mounting block 5. As the second hydraulic cylinder 10 continues to extend, it lifts the mounting block 5 upwards. The mounting block 5 slides upwards within the mounting groove 7, causing the semi-circular plate 6 fixed on the two rectangular plates 9 above it and the deep groove ball bearing fitted on the semi-circular plate 6 to rise together, thus removing the bearing from the working area of ​​the testing table 1 for easier subsequent operation. After the mounting block 5 is lifted, the operator can directly remove the deep groove ball bearing and the mounting plate 5 from the testing table 1 without using clamps to hold the deep groove ball bearing, reducing the possibility of data deviation caused by other factors. When inspecting the deep groove ball bearing, if the deep groove ball bearing is too tightly fitted to the semi-circular plate 6, this can be corrected by rotating the two bolts 11. Since the bolts 11 are threaded onto the adjacent inner walls of the circular grooves 12 at both ends of the mounting block 5, and their adjacent ends are threaded through the interior of the rectangular groove 8, and are rotatably connected to the rectangular plate 9 through the convex round rod 14, when the bolts 11 are rotated, the bolts 11 rotate within the circular grooves 12, and due to the thread action, the bolts 11 will move inwards or outwards from the rectangular groove 8. The movement of bolt 11 will cause the rectangular plate 9 to slide in the rectangular groove 8 through the convex round rod 14, thereby increasing or decreasing the distance between the two semi-circular plates 6, which facilitates the subsequent inspection and measurement of the deep groove ball bearing.
