[0002] A rolling bearing is composed of an inner ring, an outer ring, rolling elements and a cage. Due to differences in processing precision, it is impossible to ensure that the size of each ball is exactly the same, so rotational deviation will occur. After the bearing is manufactured, it is necessary to sample and test the load compression resistance and rotational deviation of the bearing to detect whether the bearing can be used. However, the currently used testing devices mainly fix the bearing through chucks for detection, which is not conducive to rapid assembly and driving to detect the rotational trajectory deviation of the outer ring of the bearing, and cannot quickly fix the bearing to provide rotational speed for testing. Content of the Utility Model

[0003] In order to overcome the above defects, the utility model provides a performance testing device for bearing operation, which solves the problems of being not conducive to rapid assembly and driving to detect the rotational trajectory deviation of the outer ring of the bearing, and cannot quickly fix the bearing to provide rotational speed for testing.

[0005] A first electric push rod is fixedly connected to one side of the fixing block, one end of the first electric push rod is fixedly connected to a rotating block, a bottom block is fixedly connected to the top end of the main body, a connecting bottom rod is fixedly connected to one side of the bottom block, a base is fixedly connected to one end of the connecting bottom rod, a second electric push rod is fixedly connected inside the base, the number of the second electric push rods is two, one end of each second electric push rod is fixedly connected to a toothed rod, and the two toothed rods are engaged with the same rotating gear, and a moving groove is formed on one side of the rotating gear.

[0006] As a further scheme of the utility model: One side of the rotating block is connected to a pressing block through a pin, and the pressing block corresponds to the moving block.

[0007] As a further scheme of the utility model: One side of the pressing block is connected inside the fixing frame through a pin, and a connecting block is fixedly connected to one side of the moving block.

[0008] As a further solution of the present utility model: the number of the connecting blocks is four, and the same reset spring is fixedly connected between two corresponding connecting blocks.

[0009] As a further solution of the present utility model: the number of the moving grooves is several, and a moving column is movably connected inside the moving groove.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. For this performance testing device for bearing operation, by setting a protective outer ring, a clamping ring, a moving block, a fixed block, a first electric push rod, a rotating block, a pressing block, and a connecting block, when the first electric push rod is started, the first electric push rod will contract and pull the rotating block. At this time, the rotating block drives the pressing block to rotate around the middle pin. When the pressing block rotates, it squeezes the moving blocks on both sides, and the moving blocks will move to both sides. The movement of the moving blocks drives the clamping ring to expand. At this time, the bearing can be placed in. Then, when the first electric push rod is restored, the reset spring drives the moving block and the clamping ring to reset, clamping the placed bearing to prevent the bearing from loosening, ensuring that the bearing is more stable during the rotation test and also making it more convenient for the installation test of the bearing.

[0013] 2. For this performance testing device for bearing operation, by setting a second electric push rod, a toothed rod, a rotating gear, a moving groove, and a moving column, when the second electric push rod is started, the second electric push rod will drive the toothed rod to move. The movement of the toothed rod drives the meshing rotating gear to rotate. When the rotating gear rotates, it drives the moving groove to change its position. At this time, the moving groove drives the moving column and the opening piece to open, and the opening piece will drive the fixing piece to open, so that the inner ring of the bearing can be fixed, which is convenient for installation and also prevents it from falling off.

[0019] The technical solution of this patent will be further described in detail below in combination with the specific implementation mode.

[0020] As Figures 1-4 shown, the present utility model provides a technical solution: a performance testing device for bearing operation, including a main body 1. A motor protection cover 2 is fixedly connected to the top end of the main body 1. A servo motor 3 is fixedly connected inside the motor protection cover 2. The output end of the servo motor 3 is fixedly connected to a rotating column 4. One end of the rotating column 4 is fixedly connected to a fixed frame 5. One side of the fixed frame 5 is fixedly connected to a telescopic block 6. The number of telescopic blocks 6 is two. One end of the telescopic block 6 is fixedly connected to a protective outer ring 8. A clamping ring 9 is fixedly connected inside the protective outer ring 8. The bottom end of the clamping ring 9 is fixedly connected to a moving block 10. The bottom end of the moving block 10 is fixedly connected to a fixed block 11. One side of the rotating block 13 is connected to an extrusion block 14 through a pin. The extrusion block 14 corresponds to the moving block 10. Through the arrangement of the extrusion block 14 and the moving block 10, the extrusion block 14 rotates around the central pin. When rotating, the two protrusions on both sides of the extrusion block 14 squeeze the moving block 10, and the moving block 10 moves to both sides, so as to facilitate the placement of the bearing;

[0021] One side of the fixed block 11 is fixedly connected to a first electric push rod 12. One end of the first electric push rod 12 is fixedly connected to a rotating block 13. One side of the extrusion block 14 is connected inside the fixed frame 5 through a pin. One side of the moving block 10 is fixedly connected to a connecting block 15. The number of connecting blocks 15 is four. The same return spring 16 is fixedly connected between two corresponding connecting blocks 15. Through the arrangement of the moving block 10 and the return spring 16, after the bearing is installed, it needs to be reset. At this time, the return spring 16 drives the moving block 10 to retract and reset, so as to fix the bearing and prevent the bearing from loosening;

[0022] At the top of the main body 1, a bottom block 17 is fixedly connected. On one side of the bottom block 17, a connecting bottom rod 18 is fixedly connected. At one end of the connecting bottom rod 18, a base 19 is fixedly connected. Inside the base 19, two second electric push rods 20 are fixedly connected. One end of each of the second electric push rods 20 is fixedly connected to a toothed rod 21. The two toothed rods 21 are engaged with the same rotating gear 22. On one side of the rotating gear 22, a plurality of moving grooves 23 are provided. Inside the moving grooves 23, moving columns 24 are movably connected. Through the arrangement of the moving grooves 23 and the moving columns 24, when the rotating gear 22 is started to rotate, the rotating gear 22 drives the moving grooves 23 to change positions. At this time, the moving grooves 23 drive the moving columns 24 and the opening pieces 25 to open, facilitating the more stable opening of the opening pieces 25, thereby facilitating the fixing work of the bearing.

[0023] At the bottom end of the moving column 24, an opening piece 25 is fixedly connected. On the opening piece 25, a fixing piece 7 is fixedly connected. Through the arrangement of the opening piece 25 and the fixing piece 7, when the opening piece 25 opens, it drives the fixing piece 7 to open, facilitating the installation of the inner ring of the bearing.

[0024] The working principle of the present utility model is as follows: First, start the first electric push rod 12. The first electric push rod 12 will contract and pull the rotating block 13. At this time, the rotating block 13 drives the pressing block 14 to rotate around the middle pin. When the pressing block 14 rotates, it presses the moving blocks 10 on both sides. The moving blocks 10 will move to both sides. The movement of the moving blocks 10 drives the clamping ring 9 to expand. At this time, the bearing can be placed in. Then, restore the first electric push rod 12. At this time, the reset spring 16 drives the moving blocks 10 and the clamping ring 9 to reset, clamping the placed bearing. Then, start the second electric push rod 20. The second electric push rod 20 will drive the toothed rod 21 to move. The movement of the toothed rod 21 drives the engaged rotating gear 22 to rotate. When the rotating gear 22 rotates, it drives the moving grooves 23 to change positions. At this time, the moving grooves 23 drive the moving columns 24 and the opening pieces 25 to open. The opening pieces 25 will drive the fixing pieces 7 to open, so that the inner ring of the bearing can be fixed. Then, start the servo motor 3 to drive the rotating column 4 and the fixed frame 5 to rotate to test the bearing.
