[0032] It should be noted that the embodiments and features in the present application can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0033] In order to enable personnel in the technical field to better understand the scheme of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0034] As shown in Figure 1 The present application provides a push rod motor performance detection device for simulating and detecting the stability of the push rod motor during operation. The push rod motor performance detection device comprises a detection table 1, the upper end of which is provided with a clamping mechanism 3 for clamping the push rod motor to be detected. A detection box 2 is also fixedly installed at the upper end of the detection table 1, which is used to detect the stroke of the push rod motor.

[0035] In order to enable the detection table 1 to adapt to operators of different heights, telescopic columns 11 are fixedly installed at the lower end of the detection table 1 at four corners. The lower end of each telescopic column 11 is fixedly installed with a base frame 12, and a gas cylinder 13 is fixedly installed at the center of the base frame 12. The output shaft of the gas cylinder 13 is fixed to the lower end of the detection table 1. Therefore, by starting the gas cylinder 13, the detection table 1 can be pushed up and down, thereby facilitating the adjustment of the height of the detection table 1.

[0036] At the same time, a roller 14 is arranged at one side of the lower end of the base frame 12, and a support leg (not marked in the figure) consistent with the height of the roller 14 is arranged at the other side. A handle 15 is also fixedly installed at one side of the detection table 1. Therefore, when the operator needs to adjust the position of the detection device, the handle 15 is manually held to lift the detection table 1, and the detection device as a whole is moved by the roller 14.

[0037] As shown in Figure 2 The clamping mechanism 3 has a sliding plate 31 fixedly installed at the upper end of the detection table 1. A fixed clamp 32 is fixedly installed at one side of the upper end of the sliding plate 31, and a support block 33 is fixedly installed at the other end of the sliding plate 31. A movable clamp 34 is slidably connected to the upper end of the sliding plate 31. One end of the movable clamp 34 close to the support block 33 is rotatably connected with a screw rod 35, which penetrates and is threadedly connected to the support block 33. An adjusting plate 36 is fixedly installed at the other end of the screw rod 35. Therefore, before the push rod motor is detected, the push rod motor is placed between the fixed clamp 32 and the movable clamp 34. Then, the adjusting plate 36 is manually rotated to make the screw rod 35 rotate, so that the movable clamp 34 moves towards the fixed clamp 32 until the push rod motor is clamped between the movable clamp 34 and the fixed clamp 32, thereby fixing the push rod motor and ensuring the stability during the detection process.

[0038] AsFigures 2-3 As shown, the detection box 2 has a bottom plate, and two groups of side plates 21 fixed to the upper end of the bottom plate, both sides of the two groups of side plates 21 are fixedly installed with horizontal plates 22, the two groups of horizontal plates 22 are fixedly installed with connecting rods 23, the connecting rods 23 are slidably connected with the baffle 24, and one side of the baffle 24 is also fixedly installed with a sliding sleeve 25, the sliding sleeve 25 is sleeved on the connecting rod 23, and the sliding sleeve 25 makes the sliding of the baffle 24 more smooth.

[0039] Meanwhile, the upper end of the bottom plate of the detection box 2 is fixedly installed with a sliding rail 26, and the lower end of the baffle 24 is fixedly installed with a sliding block 28, the sliding block 28 is slidably connected with the sliding rail 26, so as to ensure the sliding stability of the baffle 24.

[0040] Furthermore, the end face of the baffle 24 towards the sliding sleeve 25 is fixedly installed with a mounting ring 241, the mounting ring 241 is used for placing the output end of the push rod motor, and the horizontal plate 22 between the baffle 24 and the clamping mechanism 3 is provided with an opening 221, and it should be noted that the opening 221, the mounting ring 241 and the clamping surface of the fixed clamp 32 are on the same axis, so when the push rod motor is installed, the output shaft of the push rod motor is inserted into the opening 221 until the end enters the mounting ring 241.

[0041] In order to reset the baffle 24 after the position changes, a compression spring 27 is fixedly installed between the end of the baffle 24 away from the sliding sleeve 25 and the horizontal plate 22, and the compression spring 27 is sleeved on the connecting rod 23, so that when the baffle 24 is pushed, the compression spring 27 will be extruded and contracted.

[0042] The upper end of the baffle 24 is fixedly installed with a pressing plate 242 on both sides, the pressing plate 242 protrudes from the side plate 21, and the upper end of the side plate 21 is provided with a mounting hole 211, and the mounting hole 211 is placed with a pressing piece 29, and the height of the pressing piece 29 is flat with the height of the baffle 24.

[0043] The pressing piece 29 has a plate ring 292, the diameter of the plate ring 292 is greater than the diameter of the mounting hole 211, and a rubber ring 291 is fixedly installed at the lower end of the plate ring 292, the rubber ring 291 cooperates with the mounting hole 211, the upper end of the plate ring 292 is also fixedly installed with a spring 293, the upper end of the spring 293 is fixedly installed with an arc cover 294, the upper end of the arc cover 294 is provided as an arc surface, and the lower end of the arc cover 294 is fixedly installed with a convex rod 295, the convex rod 295 passes through the spring 293, the plate ring 292 and the rubber ring 291, so that when the baffle 24 drives the pressing plate 242 to slide to the pressing piece 29, through the setting of the arc angle of the pressing plate 242 and the arc cover 294, the arc cover 294 is pressed downward, so that the arc cover 294 drives the convex rod 295 to move downward.

[0044] In the application, the bottom of the mounting hole 211 is provided with a pressure sensor, and an observation screen (not shown in the figure) is arranged on one side of the detection box 2. The pressure sensor is electrically connected with the observation screen. When the pressure sensor is subjected to pressure, data will be transmitted to the observation screen, which is convenient for the operator to observe.

[0045] It should be noted that the position of the mounting hole 211 is the stroke limit position of the push rod motor.

[0046] In summary: when detecting the push rod motor, the output shaft of the push rod motor is inserted into the opening 221 until it enters the mounting ring 241, and then the movable clamp 34 is adjusted to fix the push rod motor. At this time, the driving frequency of the push rod motor is adjusted;

[0047] When the output shaft of the push rod motor extends outward, the baffle 24 and the pressing plate 242 will be pushed outward. At this time, the compression spring 27 is contracted under the pushing force until the pressing plate 242 reaches the position of the mounting hole 211, and the arc cover 294 is pushed downward. The spring 293 is contracted, and the protruding rod 295 triggers the pressure sensor downward to transmit data to the display screen;

[0048] Then the push rod motor is reset, so that the compression spring 27 is reset without pushing force, and the baffle 24 is reset to move the pressing plate 242 away from the pressing piece 29. The spring 293 is reset. Because the extension and reset speed of the push rod motor is slow, the baffle 24 will not make the mounting ring 241 separate from the push rod motor when it is reset;

[0049] Then the push rod motor continues to extend, and the above-mentioned action is repeated, so as to realize the push-pull simulation test of the push rod motor for multiple times.

[0050] In the application, the mounting hole 211 is provided with multiple groups, and each group of mounting holes 211 is provided with a pressure sensor. The distance between the multiple groups of mounting holes 211 and the baffle 24 is different for different sizes of push rod motor extension stroke.

[0051] Therefore, when detecting push rod motors of different sizes, the ring 292 is manually lifted and the rubber ring 291 is pulled out. At this time, the pressing piece 29 is completely removed.

[0052] Then the rubber ring 291 of the pressing piece 29 is inserted into the corresponding mounting hole 211, so as to reduce the procurement cost, save the cost of later calibration and maintenance equipment, and ensure the detection efficiency and speed of the detection device.

[0053] The above descriptions are only the preferred embodiments of the present application, and are not intended to limit the present application. The present application can have various modifications and changes for those skilled in the art. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
