Description

Technical Field

[0001] This utility model relates to the technical field of motor testing equipment, and specifically discloses a micro motor testing device. Background Technology

[0002] A micro motor is a small electric motor with an output power typically below several hundred watts. Micro motors are usually less than 160 millimeters in size and are characterized by their small size, light weight, high efficiency, and ease of control. Micro motors produced typically require testing equipment to check whether the noise level generated during operation is within the acceptable range in order to identify unqualified micro motors.

[0003] Chinese patent CN218524840U discloses a micro motor testing device, which includes a soundproof box, a traction mechanism, and a sound measuring head. The soundproof box is hollow and has a sound measuring cavity. A window is provided through one side wall of the soundproof box, and a door panel is movably installed on the window. The traction mechanism includes several elastic traction components, including an elastic rope and a suction cup. A wire outlet is provided through the top of the soundproof box, and a push plate for closing the wire outlet is movably installed on the wire outlet. The motor to be tested is placed into the sound testing chamber through the window, and the motor's power cord is led out of the sound testing chamber through the outlet. The suction cups are grasped and the elastic ropes are stretched to attach the suction cups to the motor housing. This allows multiple elastic traction components to pull and position the motor housing at several different locations. After the window and outlet are closed by the door panel and push plate, the sound testing chamber is sealed and a quiet testing environment is formed, which can effectively improve the accuracy of motor noise testing and prevent defective products from flowing out. However, during the use of the above device, the user needs to reach into the soundproof box to pull the multiple elastic ropes inside in order to attach the multiple suction cups to the motor in sequence and fix the motor. This affects the efficiency of motor placement and fixation to a certain extent, thus affecting the efficiency of motor testing. Therefore, in order to solve the above problems, this utility model proposes a miniature motor testing device. Utility Model Content

[0004] The present invention aims to provide a miniature motor testing device that facilitates the user in placing and removing the motor in front of and behind it, saving time in removing and discharging the motor and improving the efficiency of motor testing.

[0005] This utility model is achieved through the following technical solution:

[0006] A micro motor testing device includes a testing mechanism. A limiting mechanism is provided on the upper inner side of the testing mechanism. The testing mechanism includes a testing box, with protruding plates connected to both sides of the upper end of the testing box. A sound measuring head is connected to the bottom inner side of the testing box. A camera is connected to one end of the testing box. The limiting mechanism includes a top plate. A limiting groove is provided on the side of the top plate near the camera. A limiting plate is provided inside the limiting groove. Two first telescopic rods are symmetrically arranged below the top plate. Clamping plates are connected to the telescopic ends of the two first telescopic rods. A motor body is arranged inside the two clamping plates. Second telescopic rods are connected to both ends of the lower part of the top plate.

[0007] As a further feature of the above scheme, two support legs are symmetrically connected to the lower sides of the detection box, which can provide stable support for the detection box and its connecting components. A controller is provided on one side of the detection box to facilitate the control of the operation of the relevant components in the device.

[0008] As a further feature of the above scheme, each of the four protruding plates is provided with an insertion hole, and each of the four lower corners of the top plate is connected with an insertion rod. The insertion rod passes through the insertion hole and slides with the insertion hole, which can restrict the position of the top plate and the first telescopic rod and the motor body below it when the second telescopic rod is fully retracted.

[0009] As a further feature of the above solution, mounting rods are provided on both sides of the limiting groove, and a mounting plate is connected above the limiting plate. Mounting holes are provided on both sides of the mounting plate. The mounting rods pass through the interior of the mounting holes and slide in cooperation with the mounting holes, facilitating the disassembly and assembly of the mounting plate and the limiting plate. This allows the power cords of the motor and the first telescopic rod to be secured between the bottom of the limiting groove and the limiting plate. A handle is connected to the side of the mounting plate away from the limiting plate, making it convenient for the user to grip when disassembling and assembling the limiting plate.

[0010] As a further feature of the above solution, the outer sides of the first telescopic rod and the second telescopic rod are respectively connected to a first mounting base and a second mounting base. The first mounting base and the second mounting base are respectively connected to the top plate and the detection box, which can provide stable support for the first telescopic rod and the second telescopic rod, and facilitate the disassembly, assembly and maintenance of the above two types of telescopic rods.

[0011] As a further feature of the above solution, the clamping plate is detachably connected to the first telescopic rod, which facilitates the disassembly and maintenance of the clamping plate. An elastic pad is connected to the side of the clamping plate away from the first telescopic rod, which can prevent rigid contact between the micro motor and the clamping plate.

[0012] The controller in this invention is a PLC controller or a microcontroller controller, which can simultaneously control the extension and retraction of the two first telescopic rods and the two second telescopic rods. The first telescopic rods, the second telescopic rods, the sound measuring head, and the camera are all connected to the controller via power lines and signal lines.

[0013] The present invention has the following beneficial effects during use:

[0014] The use of cameras in the testing mechanism allows users to monitor the operation of the motor body, the first telescopic rod, and the sound measuring head located inside the testing box in real time. This enables timely adjustments to the motor testing rhythm in case of malfunctions in these components, ensuring the safety of the testing operation.

[0015] The use of two second telescopic rods in the limiting mechanism allows the top plate, the first telescopic rod, and the clamping plate to be pushed out from inside the testing box before the motor is placed. This makes it convenient for the user to place the micro motor to be tested between the two clamping plates and control the extension and retraction of the first telescopic rod so that the two clamping plates can clamp the motor, thus improving the efficiency of motor placement.

[0024] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all 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.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following will refer to the appendix... Figures 1-6 This application will be described in detail with reference to the embodiments.

[0026] An embodiment discloses a micro motor testing device, including a testing mechanism 1. A limiting mechanism 2 is provided on the upper inner side of the testing mechanism 1. The testing mechanism 1 includes a testing box 11. Both sides of the upper end of the testing box 11 are connected to protruding plates 111. A sound measuring head 13 is connected to the bottom inner side of the testing box 11. A camera 14 is connected to one end of the testing box 11. The limiting mechanism 2 includes a top plate 21. A limiting groove 211 is provided on the side of the top plate 21 near the camera 14. A limiting plate 22 is provided on the inner side of the limiting groove 211. Two first telescopic rods 24 are symmetrically arranged below the top plate 21. The telescopic ends of the two first telescopic rods 24 are connected to clamping plates 25. A motor body 3 is provided on the inner side of the two clamping plates 25. Two second telescopic rods 27 are connected to both ends of the lower part of the top plate 21.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, two support legs 12 are symmetrically connected to the lower sides of the detection box 11, which can provide stable support for the detection box 11 and its connecting parts. A controller 4 is provided on one side of the detection box 11 to facilitate the control of the operation of the relevant components in the device.

[0028] like Figure 1 and Figure 3As shown, each of the four protruding plates 111 has an insertion hole 112 inside. Each of the four lower corners of the top plate 21 is connected to an insertion rod 212. The insertion rod 212 passes through the insertion hole 112 and slides with the insertion hole 112. When the second telescopic rod 27 is fully retracted, it can restrict the position of the top plate 21, the first telescopic rod 24 below it, and the motor body 3.

[0029] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, mounting rods 213 are provided on both sides of the limiting groove 211, and a mounting plate 23 is connected above the limiting plate 22. Mounting holes 231 are provided on both sides of the mounting plate 23. The mounting rods 213 pass through the interior of the mounting holes 231 and slide with the mounting holes 231, which facilitates the disassembly and assembly of the mounting plate 23 and the limiting plate 22, so as to lock the power cord of the motor and the first telescopic rod 24 between the bottom of the limiting groove 211 and the limiting plate 22. A handle 232 is connected to the side of the mounting plate 23 away from the limiting plate 22, which is convenient for the user to grip when disassembling and assembling the limiting plate 22.

[0030] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the outer sides of the first telescopic rod 24 and the second telescopic rod 27 are respectively connected to the first mounting base 26 and the second mounting base 28. The first mounting base 26 and the second mounting base 28 are respectively connected to the top plate 21 and the detection box 11, which can provide stable support for the first telescopic rod 24 and the second telescopic rod 27, and facilitate the disassembly, assembly and maintenance of the above two telescopic rods.

[0031] like Figure 4 and Figure 5 As shown, the clamping plate 25 is detachably connected to the first telescopic rod 24, which facilitates the disassembly, assembly, and maintenance of the clamping plate 25. An elastic pad 251 is connected to the side of the clamping plate 25 away from the first telescopic rod 24, which can prevent rigid contact between the micro motor and the clamping plate 25.

[0032] This embodiment discloses a micro motor testing device. Before use, the controller 4 simultaneously controls the extension of two second telescopic rods 27 to pull the insertion rod 212 out of the insertion hole 112, separating the top plate 21 from the upper open end of the testing box 11. After the first telescopic rod 24 and the gripper are completely pushed out of the testing box 11, the controller 4 simultaneously closes the two second telescopic rods 27. Holding the handle 232, the mounting plate 23 is pulled upwards to pull the mounting rod 213 out of the mounting hole 231, separating the mounting plate 23 and the limiting plate 22 from the top plate 21. The mounting plate 23 is placed aside, and the motor body 3 of the micro motor to be tested is placed between the two clamping plates 25. The controller 4 simultaneously controls the extension of the two first telescopic rods 24, moving the two clamping plates 25 towards the motor body 3. The push causes two close-to-each elastic pads 251 to press against the motor body 3 from both sides. The elastic pads 251 and the motor body 3 come into contact and undergo reversible deformation to clamp and fix the motor body 3, preventing it from sliding during the test. The controller 4 simultaneously closes the two first telescopic rods 24. After the power cord of the motor body 3 is placed in the limiting groove 211, the limiting plate 22 and the mounting plate 23 are reset. The mounting rod 213 is inserted back into the mounting hole 231, restricting the power cord of the motor body 3 in the gap between the limiting plate 22 and the bottom of the limiting groove 211. The limiting plate 22 and the bottom of the limiting groove 211 press against the power cord of the motor body 3, reducing the open area of ​​the limiting hole and reducing the impact of external noise passing through the limiting hole on the test quality of the motor body 3.

[0033] The controller 4 simultaneously retracts the two second telescopic rods 27, causing the top plate 21 and motor body 3 to move towards the detection box 11. When the insertion rod 212 is fully inserted into the insertion hole 112, the top plate 21 and the upper surface of the protrusion plate 111 are in contact. The controller 4 then simultaneously closes the two second telescopic rods 27. The controller 4 activates the sound measuring head 13 and connects the power cord of the motor body 3 to the existing external power supply, enabling the motor body 3 to run. The noise level generated by the motor body 3 during operation is transmitted to the controller 4 in real time. The user judges whether the micro motor under test is qualified based on the transmitted data. The camera 14 can transmit the running images of the sound measuring head 13 and motor body 3 in the detection box 11 back in real time. The controller 4 allows the user to monitor the operation of relevant components in the testing box 11. After the test is completed, disconnect the power cord of the motor body 3 from the external power supply, use the controller 4 to close the sound head 13, and use the controller 4 to simultaneously control the extension of the two second telescopic rods 27. After completely pushing the first telescopic rod 24 and the motor body 3 out of the testing box 11, close the two second telescopic rods 27, grab the handle 232, pull the limit plate 22 out of the limit hole, hold the motor body 3, and use the controller 4 to control the retraction of one of the first telescopic rods 24 to release the elastic pad 251 and the clamps from fixing the motor body 3. After removing the motor body 3 from between the two clamps, repeat the above operation to continue the motor testing.

[0034] The components of the micro motor testing device disclosed in this utility model, including the motor body 3, controller 4, testing box 11, protruding plate 111, support leg 12, sound measuring head 13, camera 14, top plate 21, insertion rod 212, mounting rod 213, limiting plate 22, mounting plate 23, handle 232, first telescopic rod 24, clamping plate 25, elastic pad 251, first mounting seat 26, second telescopic rod 27, and second mounting seat 28, are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
