Description

Technical Field

[0001] This utility model relates to the field of geared motor testing technology, and in particular to a geared motor performance testing device. Background Technology

[0002] A geared motor is an integrated unit of a speed reducer and a motor. It is also commonly referred to as a geared motor or geared motor. It is mainly used to reduce the output speed of a high-speed rotating motor to the required low speed, while increasing the output torque to meet the needs of low-speed, high-torque transmission equipment. After the geared motor is completed, performance testing is a necessary requirement before it leaves the factory.

[0003] A search revealed that the utility model patent with authorization announcement number CN222232477U discloses a geared motor performance testing device, which can be used to test whether the actual output speed of the geared motor body after production meets the set speed.

[0004] Although the above-mentioned device can perform performance testing of the speed of the geared motor, in actual testing, the next geared motor can only be installed and fixed after the current geared motor under test is disassembled, and then the next geared motor under test can be tested. The interval between two adjacent testing operations is too long, and the testing efficiency is not ideal.

[0005] Therefore, it is necessary to invent a performance testing device for geared motors to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a geared motor performance testing device that allows the installation and fixing of the next motor to be installed during the testing of the previous motor. Furthermore, after the testing is completed, the output of the tested motor and the input of the motor under test are simultaneously realized, shortening the interval between adjacent testing operations and improving testing efficiency. This addresses the problem mentioned in the background art, where in the actual testing process, the next geared motor can only be installed and fixed after the current tested geared motor has been disassembled, and then the testing operation for the next tested geared motor can only proceed afterward, resulting in excessively long intervals between adjacent testing operations and unsatisfactory testing efficiency.

[0007] According to one aspect of this disclosure, the following technical solution is provided: a geared motor performance testing device, comprising:

[0008] A locking mechanism is provided for locking the synchronous switching mechanism.

[0009] A synchronous shifting mechanism includes a rotating column nested on the top of a worktable via bearings. Two sets of rotationally symmetrical motor mounting assemblies are arranged on both sides of the rotating column. Each set of motor mounting assemblies includes a fixing plate fixedly mounted on the outside of the rotating column. The bottom end of the fixing plate away from the rotating column has a locking groove adapted to a locking pin. A clearance channel for avoiding the motor shaft is formed at the center of the side of the fixing plate. Locking nuts are fixedly installed at each of the four corners of the side of the fixing plate.

[0010] A performance testing mechanism is used to test the geared motor under test.

[0011] According to at least one embodiment of the geared motor performance testing device of the present disclosure, the locking mechanism includes a workbench, and a side plate is fixedly disposed on the top right side of the workbench.

[0012] According to at least one embodiment of the geared motor performance testing device of the present disclosure, a locking pin is slidably provided through the side of the side plate, and a return spring is sleeved on the outside of the locking pin and fixedly connected between the locking pin and the side plate.

[0013] According to at least one embodiment of the geared motor performance testing device of the present disclosure, the performance testing mechanism is fixedly installed on the upright plate at the front end of the top of the workbench, and an electric push rod is fixedly installed on the front side of the upright plate.

[0014] According to at least one embodiment of the geared motor performance testing device of the present disclosure, the output shaft of the electric push rod slides through the upright plate and is fixedly connected to the rotating plate, a rubber pad is bonded to the center of the back of the rotating plate, and a testing unit is provided on both the upright plate and the rotating plate.

[0015] According to at least one embodiment of the geared motor performance testing device of the present disclosure, the testing unit includes an infrared receiver fixedly disposed on the top of the back side of the upright plate, an infrared transmitter fixedly disposed on the top of the front side of the rotating plate, a speed calculation module connected to the output end of the infrared receiver, and a display connected to the output end of the speed calculation module.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] This invention features a synchronous switching mechanism. During the testing of the geared motor on the left synchronous switching mechanism, a new geared motor is taken and its mounting holes are aligned with the mounting holes on the right fixed plate. A bolt is then passed through the mounting holes on the motor and fixed plate, and rotated to insert the bolt into the inner side of the adjacent locking nut, thus securing the motor. After the left motor test is completed and the performance testing mechanism is reset, the locking pin is pulled to the right, moving it out of the adjacent locking slot. The fixed plate is then rotated around the rotating column, causing the tested motor to move out of the testing station. Simultaneously, the tested motor moves from the disassembly / assembly station to the testing station. Finally, the locking pin is released, and it re-inserts into the adjacent locking slot to lock. Compared to existing technologies, this invention allows for the installation and fixing of the next motor during the testing of the previous motor. This enables simultaneous output from the tested motor and input from the motor under test after testing, shortening the interval between adjacent testing operations and improving testing efficiency.

[0026] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0027] Figure 1 This is a schematic diagram of the overall structure of a geared motor performance testing device according to one embodiment of the present disclosure.

[0028] Figure 2 This is a schematic diagram of the locking mechanism 1 and the performance testing mechanism 3 of a geared motor performance testing device according to one embodiment of the present disclosure.

[0029] Figure 3 This is a schematic diagram of the synchronous switching mechanism 2 of a geared motor performance testing device according to one embodiment of the present disclosure.

[0030] like Figures 1-3 As shown, the geared motor performance testing device disclosed herein may include components such as a locking mechanism 1, a synchronous shifting mechanism 2, and a performance testing mechanism 3.

[0031] like Figure 2 As shown in this disclosure, the locking mechanism 1 includes a workbench 11, a side plate 12 is fixedly installed on the top right side of the workbench 11, a locking pin 13 is slidably installed through the side of the side plate 12, and a return spring 14 is sleeved on the outside of the locking pin 13 and fixedly connected between the locking pin 13 and the side plate 12.

[0032] Therefore, the locking pin 13 can be inserted into the inner side of the adjacent locking groove 23 to lock the entire synchronous switching mechanism 2, so as to complete the positioning of the synchronous switching mechanism 2 and keep the tested motor in the testing position. When it is necessary to rotate the synchronous switching mechanism 2, the locking pin 13 is pulled to the right and the locking pin 13 is moved out from the inner side of the adjacent locking groove 23. At the same time, the return spring 14 is stretched. When the locking pin 13 is released later, the stretched return spring 14 drives the locking pin 13 to move to the left and reset.

[0033] like Figure 3As shown, in a preferred embodiment, the synchronous shifting mechanism 2 includes a rotating column 21 that is nested on the top of the worktable 11 via a bearing. Two sets of rotationally symmetrical motor mounting assemblies are provided on both sides of the rotating column 21. Each set of motor mounting assemblies includes a fixing plate 22 fixedly disposed on the outside of the rotating column 21. The bottom of the fixing plate 22 away from the rotating column 21 has a locking groove 23 adapted to the locking pin 13. A clearance channel 24 for avoiding the motor shaft is provided at the center of the side of the fixing plate 22. Locking nuts 25 are fixedly disposed at the four corners of the side of the fixing plate 22.

[0034] Therefore, during the testing of the geared motor on the left synchronous switching mechanism 2, a new geared motor to be tested is picked up and its mounting hole is aligned with the mounting hole on the right fixed plate 22. Then, a bolt is passed through the mounting hole on the motor and the fixed plate 22, and the bolt is rotated so that it enters the inner side of the adjacent locking nut 25 and fixes the motor. After the left motor test is completed and the performance testing mechanism 3 is reset, the locking pin 13 is pulled to the right so that it moves out from the inner side of the adjacent locking groove 23. Then, the fixed plate 22 is rotated around the rotating column 21 as the axis, so that the tested motor moves out from the testing station. At the same time, the tested motor moves from the disassembly station to the testing station. Finally, the locking pin 13 is released and inserted back into the inner side of the adjacent locking groove 23 to lock. Compared with the prior art, this utility model can perform the installation and fixing operation of the next motor during the testing of the previous motor. Thus, after the test is completed, the output of the tested motor and the input of the tested motor are realized simultaneously, shortening the interval time between the testing operations on both sides and improving the testing efficiency.

[0035] like Figure 2 As shown in this disclosure, the performance testing mechanism 3 is fixedly installed on the upright plate 31 at the front end of the top of the workbench 11. An electric push rod 32 is fixedly installed on the front of the upright plate 31. The output shaft of the electric push rod 32 slides through the upright plate 31 and is fixedly connected to a rotating plate 33. A rubber pad 34 is glued to the center of the back of the rotating plate 33. A testing unit is jointly installed on the upright plate 31 and the rotating plate 33.

[0036] Therefore, after the motor under test arrives at the testing station, the electric push rod 32 drives the rotating plate 33 to move backward until the end of the output shaft of the motor under test is pressed against the rubber pad 34 and deformed. Then, the power supply of the motor under test is turned on. After starting, the motor under test drives the rotating plate 33 to rotate continuously under the action of friction. During this process, the testing unit completes the testing of the motor under test. After the testing is completed, the electric push rod 32 drives the rotating plate 33 to move forward continuously, thereby avoiding obstruction to the rotation of the subsequent synchronous switching mechanism 2.

[0037] It should also be noted that the detection unit includes an infrared receiver fixedly installed on the top of the back of the upright plate 31, an infrared transmitter fixedly installed on the top of the front of the rotating plate 33, a rotation speed calculation module connected to the output end of the infrared receiver, and a display connected to the output end of the rotation speed calculation module.

[0038] The aforementioned detection unit is a publicly disclosed solution in the prior art and is not a necessary technical feature of this application. Therefore, this application will not elaborate on its specific working principle here.

[0039] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0040] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
