Description

Technical Field

[0001] The utility model relates to the technical field of motor testing, in particular to a testing platform which is convenient for fixing a motor. Background Art

[0002] Servo motors can control speed and position with high accuracy, and can convert voltage signals into torque and speed to drive the controlled object. Currently, a motor test platform is required in the process of testing the motor, but the existing motor test platform cannot fix and clamp the motor, resulting in reduced test stability.

[0003] For example, a motor testing platform disclosed in publication number CN217521329U drives a fixed clamping plate and a limit plate to approach two sides of the motor through a threaded sleeve, thereby fixing and clamping the motor, which is beneficial to improving stability during the test and avoiding the hidden danger of damage caused by the motor falling off.

[0004] However, the practicality of this clamping structure is poor when in use. When clamping different motors, this clamping structure needs to start the double-headed motor to rotate and clamp, which is rather troublesome. In addition, when the fixed clamp is used to clamp the motor, it is easy for the motor casing to be damaged by friction due to excessive movement, thereby reducing the practicality of the device. In view of this, we propose a test platform that is convenient for fixing motors. Utility Model Content

[0005] The purpose of the utility model is to provide a test platform which is convenient for fixing a motor, so as to solve the problems raised in the above background technology.

[0015] Compared with the prior art, the utility model provides a test platform that is convenient for fixing the motor, and has the following beneficial effects:

[0016] 1. The test platform for fixing the motor is convenient for supporting and fixing both sides of the motor by setting a fixed structure. The user can put the motor into the test frame for placement. At this time, the motor presses the bottom plate and the moving rod downward. The moving rod moves downward to drive the pressure plate to press the second airbag downward, so that the second airbag is squeezed and deformed and the gas inside it is passed into the first airbag through the ventilation pipe. The two groups of first airbags are expanded to fix the two sides of the motor, so that the device is convenient to use and avoids friction damage to the motor casing due to excessive movement when the motor is clamped.

[0017] 2. The test platform for fixing the motor is convenient for limiting the bottom plate by setting a positioning structure, so as to avoid the contact between the detection part and the motor and cause it to move downward during subsequent motor testing. The sleeve on its surface is driven to move by rotating the screw, and the movement of the sleeve drives the connecting rod of its side wall to move. The movement of the connecting rod drives the two sets of sliders to move inside the slide groove, so that the limit rod enters the limit opening, and then completes the fixation of the bottom plate and the detection frame, thereby improving the practicality of the device.

A fixing plate 37 is fixedly installed at the end, a first airbag 38 is fixedly installed on the side wall of the fixing plate 37, a second airbag 39 is fixedly installed on the inner wall of the cavity 31, the first airbag 38 and the second airbag 39 are connected through a ventilation pipe 310, a positioning structure 4 is provided inside the bottom plate 34, a handle 6 is fixedly installed at the lower end of the screw rod 45, the lower end of the handle 6 passes through the side wall of the bottom plate 34, one end of the return spring 36 is fixedly connected to the lower end of the bottom plate 34, and the other end of the return spring 36 is fixedly connected to the surface of the detection frame 5, and a pressing plate 7 is fixedly installed at the lower end of the two groups of moving rods 35. Half of the gas volume is filled in the two groups of first airbags 38, and the interior of the second airbag 39 is in a state of sufficient gas.

[0024] Specifically, the fixing structure 3 of the technical solution of the utility model includes: a cavity 31, an opening 32, a support plate 33, a bottom plate 34, a moving rod 35, a return spring 36, a fixing plate 37, a first airbag 38, a second airbag 39, and a ventilation pipe 310.

[0025] In one embodiment of the present invention, a fixing structure 3 is provided to facilitate supporting and fixing the two sides of the motor, and a supporting frame 2 is provided to connect the two sides of the detection frame 5. The support frame 2 is provided with a lifting mechanism disclosed in the original application. This is an existing public technology and is not described here. Two sets of first air bags 38 are provided to expand and fix the two sides of the motor, thereby preventing the side walls of the motor from being easily damaged when the clamping plate and other devices are clamped on the motor. When testing the motor, the user can put the motor into the detection frame 5 for placement. At this time, the motor is in contact with the bottom plate 34, and then the bottom plate 34 is driven to move downward under the pressure of the weight of the motor, and the bottom plate 34 is lifted. By moving the moving rod 35 and squeezing the return spring 36, the moving rod 35 drives the pressure plate 7 at its lower end to move. At this time, the pressure plate 7 moves downward to squeeze the upper end of the second airbag 39, so that the upper end of the second airbag 39 is squeezed and deformed and the gas inside it is respectively passed into the two groups of first airbags 38 through two groups of ventilation pipes 310, so that the two sides of the motor are fixed by the expansion of the two groups of first airbags 38, so as to facilitate the use of the device and avoid friction damage to the motor casing due to excessive movement when clamping the motor. Anti-slip strips are provided on the side walls of the first airbag 38 to further improve the support stability of the motor side walls.

[0026] Please continue reading Figure 1-Figure 4 The positioning structure 4 includes a device cavity 41 opened on the inner wall of the bottom plate 34, and a slide groove 42 is opened on both sides of the upper end of the bottom plate 34. The inner wall of the slide groove 42 is slidably connected with a slider 43, and a limit rod 44 is fixedly installed on the side wall of the slider 43. The inner wall of the device cavity 41 is rotatably connected with a screw 45 through a shaft sleeve, and a sleeve 46 is threadedly connected to the surface of the screw 45. One end of a connecting rod 47 is hinged to the side wall of the sleeve 46, and the other end of the connecting rod 47 is hinged to the side wall of the lower end of the slider 43. A plurality of groups of limit openings 48 are opened on both sides of the inner wall of the detection frame 5. By setting the positioning structure 4, it is convenient to limit the bottom plate 34, thereby avoiding the subsequent motor detection when the detection part is connected to the motor. After the touch, the weight will increase, so that the bottom plate 34 will continue to move downward, causing the instability of the motor. Therefore, the user can drive the screw 45 to rotate by turning the handle 6, and the rotation of the screw 45 drives the sleeve 46 on its surface to move upward. At this time, the sleeve 46 moves upward and drives the connecting rod 47 of its side wall to move. The movement of the connecting rod 47 drives the two groups of sliders 43 hinged to it to move inside the slide groove 42, so that the limit rod 44 on the side wall of the slider 43 enters the limit opening 48 at different heights, and then completes the fixation of the pressure plate 7 and the detection frame 5, thereby improving the practicability of the device and further improving the stability of the motor during detection.

[0027] During operation, the user can move the base 1 as a whole, and then place the motor inside the detection frame 5. At this time, the motor is in contact with the bottom plate 34. At this time, the motor's own weight will drive the bottom plate 34 to move downward. The bottom plate 34 moves through the moving rod 35 and squeezes the reset spring 36, so that the moving rod 35 drives the pressure plate 7 at its lower end to move. At this time, the pressure plate 7 moves downward to squeeze the upper end of the second airbag 39, so that the upper end of the second airbag 39 is squeezed and deformed, and the gas inside it is respectively passed into the two groups of first airbags through the two groups of ventilation pipes 310 38, so that the two sides of the motor are fixed by expanding the two groups of first air bags 38, and then the screw 45 is driven to rotate by turning the handle 6, and the sleeve 46 on the surface of the screw 45 is driven to move upward by the rotation of the screw 45. At this time, the sleeve 46 moves upward and drives the connecting rod 47 of its side wall to move. The movement of the connecting rod 47 drives the two groups of sliders 43 hinged thereto to move inside the slide groove 42, so that the limit rod 44 on the side wall of the slider 43 enters the limit opening 48 at different heights, thereby completing the fixation of the pressure plate 7 and the detection frame 5, thereby further improving the stability of the motor during detection.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
