Detailed Implementation
[0018] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the invention. Example 1
[0019] like Figures 1-3 As shown, the dynamic installation and testing fixture for the reducer motor of the present invention includes a mechanical flipping fixture 1, a power mechanism, and a wireless vibration sensor 5. The power mechanism includes a driver 2 and a host computer 3. The mechanical flipping fixture 1 provides fixing and flipping support for the reducer motor assembly 4, while the driver 2 and the host computer 3, as the power mechanism, provide power and control signals to the motor. The wireless vibration sensor 5 is used to detect vibration signals on the mechanical flipping fixture 1.
[0020] The mechanical flipping fixture 1 includes a flipping bracket 101, a connecting sheet metal 102, a flipping platform 103, locking screws 104, positioning screws 105, a reducer cover 106, and guide posts 107. The flipping bracket 101, connecting sheet metal 102, flipping platform 103, locking screws 104, and positioning screws 105 together form the main body of the mechanical flipping fixture 1, providing fixation and flipping support for the reducer motor assembly 4.
[0021] The turnover support 101 includes two opposite panels, the bottom of the panel is processed with a plurality of screw holes for fixing and installing the mechanical turnover tool 1 on the fixed platform to ensure the basic assembly accuracy. The middle part of the panel is processed with a square hole for facilitating manual handling of the mechanical turnover tool 1. The end face of the panel is processed with a screw hole, and the connecting sheet metal 102 is installed between the end faces of the two side panels through the screw hole, which plays a role in connecting and fastening. The upper part of the panel is processed with a plurality of turnover screw holes, and the plurality of turnover screw holes are arranged at an interval of 45° in a circumferential direction. The turnover screw holes on the two side panels are used for installing the turnover platform 103. The plurality of turnover screw holes provided on the turnover support 101 facilitate the adaptation of different turnover platforms 103, and the assembly of different speed reducers and motors can be realized.
[0022] The two sides of the turnover platform 103 are processed with screw holes corresponding to the turnover screw holes, and the turnover platform 103 and the turnover support 101 can be fixed and positioned at a discrete angle by installing screws at the corresponding positions. The two sides of the turnover platform 103 are provided with positioning shafts 108, which can be movably installed in one group of turnover screw holes on the turnover platform 103, and the turnover platform 103 and the turnover support 101 are locked by the locking screw 104. The locking screw 104 can be loosened and tightened to loosen and tighten the turnover platform 103, thereby realizing the rotation of the turnover platform 103 at any angle. Since the turnover platform 103 is installed on the turnover support 101 through the positioning shaft 108, even if the locking screw 104 is completely removed, the turnover platform 103 will not fall off, ensuring safety. The turnover platform 103 can rotate 360°, and the locking screw 104 can be tightened when it needs to be tightened. The positioning screw 105 can be installed in the other corresponding turnover screw holes of the turnover platform 103 and the turnover support 101. The positioning screw 105 can further reinforce the turnover platform 103 at a specific angle, and in the case where it is not convenient to tighten the locking screw 104 while rotating the turnover platform 103, the positioning screw 105 can be slightly screwed in to position the turnover platform 103.
[0023] The middle part of the turnover platform 103 is processed with a mounting hole, and a circle of mounting screw holes is processed outside the mounting hole. The speed reducer and motor assembly 4 is fixed and installed through the screw holes, and a guide column 107 is installed on two opposite positions of the mounting screw holes. The guide column 107 plays a guiding role when the speed reducer and motor assembly 4 is installed on the turnover platform 103, avoiding the collision between the speed reducer and motor assembly 4 and the mechanical turnover tool 1, which affects the subsequent assembly quality on the robot.
[0024] The speed reducer cover 106 is located above the turnover platform 103 and is installed on the output hole of the speed reducer body to prevent the lubricating grease in the speed reducer from being thrown out when the wave generator rotates.
[0025] The driver 2 and the upper computer 3 of the power mechanism provide power for the motor in use, and the motor, the driver 2 and the upper computer 3 are sequentially connected.
[0026] The wireless vibration sensor 5 is fixed on the mechanical turnover tool 1 and can be fixed in a pasting manner. When the motor is reversed, the wireless vibration sensor 5 can detect the vibration signal on the tool.
[0027] In use, the wireless vibration sensor 5 is pasted on the mechanical turnover tool 1 first; the reducer motor assembly 4 is placed on the mechanical turnover tool 1 through the guide column 107 and locked by a screw, and a certain gap is left between the reducer motor assembly 4 and the mechanical turnover tool 1 to avoid scratching the reducer motor assembly 4 by the mechanical turnover tool 1; the motor is connected with the power mechanism, specifically, the motor is sequentially connected with the driver 2 and the upper computer 3; then the reducer cover 106 is installed and locked by a screw; the mechanical turnover tool 1 is turned over, the motor is above the reducer, and the motor fixing screw is loosened; the motor is started to rotate at a constant speed; the cross intersection method is adopted, the motor fixing screw is locked with increasing torque until the required locking torque of the motor fixing screw is reached; after the motor fixing screw is locked again, the motor rotation is stopped, the mechanical turnover tool 1 is turned over, the motor is below the reducer, and the dynamic assembly is completed; the motor is started to rotate forward and reverse at different speeds during detection to obtain vibration values at different speeds, which are used to judge whether the assembly is qualified.
[0028] When the mechanical turnover tool is used to assemble the reducer motor assembly, the motor shaft is rotated (wave generator is rotated) to automatically align the center of the motor shaft (wave generator) in the reducer body, so that the best coaxial assembly is achieved. The detection tool can quickly detect the assembly qualification rate and is easy to use. Example 2
[0029] Another technical solution of the application is a dynamic installation detection method for a reducer motor, which utilizes the dynamic installation detection tool for a reducer motor in example 1 and specifically includes the following steps: (1) Paste the wireless vibration sensor 5 on the mechanical turnover tool 1; (2) Start the motor, considering that the industrial robot is a high-speed moving machine, the motor is run at a constant speed at a rotation speed of 3000 rpm, if the reducer runs smoothly without abnormal sound, the next step can be performed, otherwise, reassemble; (3) After stopping the motor, reverse the motor to run at a constant speed at a rotation speed of 3000 rpm, if the reducer runs smoothly without abnormal sound, the next step can be performed, otherwise, reassemble; (4) After stopping the motor, the motor speed is increased from 0 rpm to 6000 rpm, the motor is operated in forward rotation, the vibration values of the wireless vibration sensor 5 at each speed are collected by the upper computer 3, as shown in the figure, wherein the abscissa represents the speed, the ordinate represents the vibration value, if the vibration value is within the preset range, the next step is performed, otherwise it is reassembled; Figure 4 (5) After stopping the motor, the motor speed is increased from 0 rpm to 6000 rpm, the motor is operated in reverse rotation, the vibration values of the wireless vibration sensor 5 at each speed are collected by the upper computer 3, if the vibration value is within the preset range, the robot whole machine is assembled or stored in the robot joint qualified product warehouse, otherwise it is reassembled.
[0030] The preset range in the above steps can be an industry standard range or a standard set by the manufacturer, and can be set according to the actual situation of different models of equipment, which is not specifically limited here.
[0031] The dynamic installation detection method of the speed reducer motor can judge whether the assembly is qualified by detecting the vibration degree of the speed reducer motor assembly at different motor speeds. Through the detection method, the unqualified robot joints can be detected in advance, and the rework after finding unqualified joints in the robot whole machine can be avoided.
[0032] Although the present application has been described in detail above with general description and specific embodiments, some modifications or improvements can be made on the basis of the present application, which is obvious to those skilled in the art. Therefore, these modifications or improvements made on the basis of not deviating from the spirit of the present application, all belong to the scope of the present application.
