[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-3The utility model provides an embodiment: a fixing device for testing motor performance, comprising a U-shaped seat 1, two U-shaped grooves 2 are provided on both sides of the interior of the U-shaped seat 1, a moving rod 3 is slidably connected to the interior of the two groups of U-shaped grooves 2, a piston 4 is fixedly connected to the bottom of each moving rod 3, the outer wall of the piston 4 is slidably connected to the inner wall of the U-shaped groove 2, a silicone pad 2 16 is fixedly connected to the top of each moving rod 3, a spring 5 is fixedly connected to the top of the piston 4, and the other end of the spring 5 is fixedly connected to the inner wall of the U-shaped groove 2. When the top of the silicone pad 2 16 is subjected to the gravity of the motor, the moving rod 3 is driven to move downward inside the U-shaped groove 2, and then the piston 4 is driven to move downward, so that the spring 5 is stretched to generate a rebound reaction force, which is convenient for the subsequent automatic resetting of the moving rod 3, the inner tops of the two groups of U-shaped grooves 2 are slidably connected to the moving rod 2 7, one end of each moving rod 2 7 is fixedly connected to the piston 2 8, the outer wall of the piston 2 8 The wall is slidably connected to the inner wall of the U-shaped groove 2, and the outer wall of the piston 28 is fixedly connected with a spring 29, and the other side of the spring 29 is fixedly connected to the inner wall of the U-shaped groove 2, and the other end of the moving rod 27 is fixedly connected with a silicone pad 10. The space between the piston 28 and the inner wall of the U-shaped groove 2 on the other side is filled with hydraulic oil 6. As the piston 14 moves downward, the hydraulic oil 6 will be pushed toward the piston 28, thereby pushing the piston 28 to drive the moving rod 27 to move, and then squeezing the spring 29, so that the spring 29 is compressed and a rebound reaction is generated, so that the moving rod 27 drives the silicone pad 10 to move toward the outer wall of the motor, so that under the relative squeezing force on both sides, the purpose of firmly clamping the motor under test is achieved, thereby avoiding the problem of loose clamping of the traditional clamping device after long-term use, thereby ensuring the accuracy of the motor test, and the left and right sides of the U-shaped seat 1 are provided with buffer components, and the outer wall of the U-shaped seat 1 is provided with an adjustment release component.

[0023] The buffer assembly includes two mounting grooves 17, the outer walls of the two mounting grooves 17 are both opened on the outer wall of the U-shaped seat 1, the inner walls of the two mounting grooves 17 are fixedly connected with limit rods 18, the outer walls of each limit rod 18 are sleeved with springs three 19 on both sides, the outer wall of each limit rod 18 is slidably connected with two moving blocks 20, the separated sides of the two moving blocks 20 are fixedly connected to the opposite sides of the two springs three 19, the outer wall of each moving block 20 is rotatably connected with a buffer rod 21, and the other end of each group of buffer rods 21 is rotatably connected with a moving rubber plate 22. When the motor is vibrated, it will drive the buffer rod to move, and then the moving block moves on the outer wall of the limit rod, thereby squeezing or compressing the spring three 19, generating a rebound reaction force, and then driving the buffer rod to reset, so that the moving rubber plate is reset, so that the vibration generated by the motor is weakened and eliminated, thereby solving the problem of external vibration or interference of the motor during the test process, thereby further improving the accuracy of the test results.

[0024] Two limit grooves 24 are provided on the left and right sides of the U-shaped seat 1, and two limit blocks 23 are fixedly connected to the bottom of the two movable rubber plates 22, and the outer wall of each limit block 23 is slidably connected to the inner wall of the limit groove 24. When the movable rubber plate moves, the limit block moves inside the limit groove, thereby limiting the movable rubber plate to keep moving in a straight line.

[0025] The regulating and releasing assembly includes a plurality of electric valves 11, the outer wall of each electric valve 11 is fixedly connected to the outer wall of the U-shaped seat 1, a liquid guide tube 12 is fixedly connected to the middle part of each electric valve 11, the other end of the liquid guide tube 12 is fixedly connected to a screw pump 13, the output end of the screw pump 13 is fixedly connected to a connecting tube 14, the other end of the connecting tube 14 is fixedly connected to an electric valve 2 15, and the other end of the electric valve 2 15 is fixedly connected to the outer wall of the U-shaped seat 1. When it is necessary to remove the motor, the electric valve 11 can be started to open the electric valve 11, thereby connecting the U-shaped groove 2 and the liquid guide tube 12. At this time, the hydraulic oil 6 enters the interior of the liquid guide tube 12. At this time, under the action of the screw pump 13, the hydraulic pressure enters the interior of the connecting tube 14, and then the electric valve 11 is closed, and the electric valve 2 15 is opened, so that the connecting tube 14 and the U-shaped groove 2 are connected. Under the suction force of the screw pump 13, the hydraulic oil 6 returns to the interior of the U-shaped groove 2, so that the spring 2 9 drives the moving rod 2 7 to reset. At this time, the motor is removed, and the moving rod 3 is also reset under the action of the spring 1 5.

[0026] The electric valve 1 11 and the electric valve 2 15 are both connected to the interior of the U-shaped groove 2 , thereby facilitating the flow of the hydraulic oil 6 .

[0027] The moving rod 1 3 and the moving rod 2 7 are in a vertical line.

[0028] The two groups of moving rods 3 are located in the middle of the two moving rubber plates 22.

[0029] Working principle: When performing a performance test on the motor, first place the motor to be tested on the U-shaped seat 1. With the weight of the motor, the silicone pad 2 16 will drive the moving rod 1 3 to move downward, and then drive the piston 1 4 to move downward, so that the spring 1 5 is stretched, and then the hydraulic oil 6 is pushed to move inside the U-shaped groove 2, thereby pushing the piston 2 8 to move in the direction of the silicone pad 10, and then squeezing the spring 2 9, so that the spring 2 9 is compressed to produce a rebound reaction force, and driving the moving rod 2 7 to drive the silicone pad 10 to move toward the outer wall of the motor, so that under the relative action of the two sides, the motor is fixed on the top of the U-shaped seat 1. During the test, if there is the influence of vibration, if the motor shakes, it will apply a force to the moving rubber plates 22 on both sides, so that the buffer rod 21 is active, thereby driving the moving block 20 to squeeze the spring 3 19, and then the spring 3 19 is compressed to produce a rebound reaction force, thereby pushing the moving block 20 to reset, eliminating the force generated by the vibration, and protecting the accuracy of the motor test.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
