DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-4 A device for detecting the service life of a motor comprises a base 1, a mounting seat 2 is fixedly mounted on one side of the top of the base 1, and a detection frame 4 is slidably connected to the other side of the base 1 through a slide rail 3, a clamping assembly 6 for fixing a motor 5 is provided in the mounting seat 2, and a fixing piece 7 is provided on the top of the detection frame 4, and the fixing piece 7 is used to prevent the detection frame 4 from sliding.

[0021] It is worth mentioning that, because the motor 5 needs to be clamped and fixed, the position of the detection frame 4 needs to be adjusted by the slide rail 3, so that the coupling 42 is conveniently connected to the shaft end of the motor 5;

[0022] Furthermore, the mounting seat 2 is provided with a mounting groove 21 for placing the motor 5, and grooves 22 are provided on both sides of the mounting groove 21. The detection frame 4 is rotatably connected to a rotating shaft 41 inside, and one end of the rotating shaft 41 can be connected to the shaft end of the motor 5 through a coupling 42. A pressure gauge 43 is installed on the top of the detection frame 4, and a detection head 44 is connected to the pressure gauge 43, and the detection head 44 is in close contact with the rotating shaft 41.

[0023] It should be supplemented that a rotary encoder is provided at the other end of the rotating shaft 41, a detection unit is provided at the top of the base 1, the pressure gauge 43 and the rotary encoder are electrically connected to the detection unit, the pressure gauge 43 is attached to the surface of the rotating shaft 41 through the detection head 44, and the current reading of the pressure gauge 43 is recorded. When the pressure gauge 43 changes, it indicates that the rotor of the motor 5 is damaged. By using the rotary encoder and the pressure gauge 43 in combination, the service life of the motor 5 can be effectively detected;

[0024] In addition, the coupling 42 is fixedly connected to one end of the rotating shaft 41, so that the position of the detection frame 4 can be adjusted to facilitate connection with the shaft end of the motor 5, which is convenient and quick;

[0025] Among them, because the motor 5 is placed in the installation groove 21, the groove 22 provides a rotation space for the shaft end of the motor 5 on the one hand, and on the other hand, the grooves 22 on both sides facilitate the removal of the motor 5.

[0026] Furthermore, the clamping assembly 6 includes a plurality of receiving grooves 61 provided on the other two sides of the mounting base 2, and a cylinder 62 is fixedly installed in the receiving groove 61. A clamping plate 63 is provided on the top of the cylinder 62, and its shaft end is rotatably connected to one end of the clamping plate 63.

[0027] In more detail, a fixing seat 64 is fixedly installed on the top of the mounting seat 2, and both sides of the fixing seat 64 are rotatably connected to the other end of the clamping plate 63 through a connecting rod 65. The bottom surface of the clamping plate 63 is provided with an anti-slip pad and can press against the motor 5.

[0028] The specific operation is that, through the action of the telescopic shaft end of the cylinder 62, the connecting rod 65 is cooperated to drive the clamping plate 63 to make it flip, and a plurality of the clamping plates 63 can be used to clamp and fix the motor 5 to prevent the motor 5 from shaking, which is convenient for detection.

[0029] In general, the fixing member 7 includes a base 71, a plurality of limiting holes 72 are penetrated through the top of the slide rail 3, the base 71 is fixedly installed on the top of the side of the detection frame 4, a limiting rod 73 is slidably connected inside the base 71, the top of the limiting rod 73 penetrates the base 71 and is rotatably connected to an unlocking block 74, and the bottom of the limiting rod 73 can be inserted into the limiting hole 72.

[0030] Specifically, under normal circumstances, the detection frame 4 can be fixed by inserting the limiting rod 73 into the limiting hole 72 , and the detection frame 4 is fixed to prevent the rotation of the rotating shaft 41 and cause the detection frame 4 to move.

[0031] Finally, the interior of the holder 71 can accommodate the limiting rod 73, one side of the unlocking block 74 is provided with an avoidance groove 741, and the end thereof provided with the avoidance groove 741 can contact the holder 71 when flipped, and the outer sleeve of the limiting rod 73 is provided with a spring 75, and the two ends of the spring 75 are respectively fixedly connected to the inner side surface of the holder 71 and one end of the limiting rod 73.

[0032] It should be noted that, because the unlocking block 74 can be turned over and abut against the clamping seat 71, the unlocking block 74 can drive the limiting rod 73 to move upward to make it disengage from the limiting hole 72 and come into the clamping seat 71. At this time, the detection frame 4 can move freely, and because the unlocking block 74 is turned over, the avoidance groove 741 can be locked with the limiting rod 73 anyway;

[0033] Afterwards, the unlocking block 74 is flipped again to return to its original position. Under the action of the spring 75, the limiting rod 73 returns to its original position. In addition, due to the action of the spring 75, the unlocking block 74 can be prevented from being flipped at will due to accidental touch.

[0034] Working mode: When working, the motor 5 is placed in the mounting groove 21, and the shaft end of the cylinder 62 cooperates with the connecting rod 65 to drive the clamping plate 63 to flip when retracting, so as to achieve the function of clamping and fixing the motor 5;

[0035] Afterwards, push the detection frame 4 to connect the coupling 42 and the shaft end of the motor 5 together, then flip the unlocking block 74, and under the action of the spring 75, the limit rod 73 moves down and is inserted into the limit hole 72 to fix the detection frame 4. The shaft end of the motor 5 drives the rotating shaft 41 to rotate, and the service life of the motor 5 is tested under the action of the pressure gauge 43, and the motor 5 is taken out through the groove 22.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
