Description

Technical Field

[0001] The utility model belongs to the technical field of motor shaft processing, and particularly relates to a torsion detection device for the production of motor rotating shafts. Background Art

[0002] There is a great demand for torsion tests in the market, such as torsion fatigue, static torsion, torsion impact tests on shafts. However, the existing test benches are linear and drive reciprocating motion in a straight line through a linear oil cylinder, and cannot perform axial torsion fatigue, static torsion, torsion impact and other tests. Moreover, the existing motor shaft torsion devices are difficult to control by providing torsion through hydraulic equipment, and it is easy to damage the sample shaft body and the fixing structure due to excessive torsion during use. At the same time, the uncontrollable torsion makes it difficult to accurately detect the anti-torsion ability of the shaft body.

[0003] Therefore, a torsion test bench with the publication number of "CN221078332U" belongs to the technical field of testing equipment, including a test base. A sample rotating shaft is arranged on the top of the test base, a driving motor is installed on the top of the test base, a driving shaft is installed on one side of the driving motor, a planetary gear reducer is fixedly connected to the top of the test base, an output shaft is installed on one side of the planetary gear reducer, a coupling is installed on one side of the output shaft, a controller is installed on the outer wall of the driving motor, an input wire is arranged on the top of the controller, and a mounting base is fixedly connected to the bottom of the driving motor. The driving motor drives the driving shaft to rotate, and after deceleration by the planetary gear reducer, torsion is applied to the sample rotating shaft through the output shaft, and the torsion of the driving motor is controlled by the controller. This application method is easier to control the size of the torsion, thus avoiding damage to the fixing structure and the sample rotating shaft, and at the same time making the detection result of the device more accurate.

[0004] However, for the above torsion test bench, although one end of the sample rotating shaft is connected to the output shaft through a coupling bolt on the coupling, then the limiting seat is toggled until the limiting groove on the outer wall of the other end of the sample rotating shaft completely enters the limiting ring, and then the locking bolt is screwed into the locking threaded hole to position the sample rotating shaft before testing. Finally, the user can lock the limiting seat through the positioning bolt on the limiting slide plate. There are still the following obvious defects during use: in the motor shaft test, one end is connected to the planetary gear reducer for detecting torque through a coupling with a flange connection part, and is locked and fixed by multiple groups of screws. Therefore, during the disassembly and assembly detection of the motor shaft, it takes a long time for manual feeding and discharging, which makes the feeding and discharging of the motor shaft more cumbersome and affects the torsion detection progress of the motor shaft.

And the sliding seat continues to slide on the strip-shaped track so that the other end of the motor rotating shaft is inserted into the torque docking groove of the inner hexagon for limited fixation. Then, the torque sensor can be used to detect the torque of the motor rotating shaft. When the above structure unloads the motor rotating shaft, it only needs to disengage from the torque docking groove and the limit cylindrical groove of the casing, so that the rapid unloading and loading of the motor rotating shaft can be realized, the time for loading and unloading the motor rotating shaft can be shortened, and the efficiency and convenience of the torque detection of the motor rotating shaft can be further improved.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1-5 The utility model provides a technical solution: a torque detection device for motor shaft production, comprising:

[0024] A machine 1, wherein one side of the end of the machine 1 is provided with a driving motor 2 for rotating and driving a motor shaft 14 to be processed for torque detection, a connecting flange is provided on the rotating shaft of the driving motor 2, one end of the rotating shaft of the driving motor 2 is connected to a reduction gear box 3 for torque transmission of the motor shaft to be processed through a coupling transmission, a flange connecting plate connected to the connecting flange is provided on the input shaft of the reduction gear box 3, so that the equipment can be easily disassembled and repaired after a failure occurs in the later stage, and the reduction gear box 3 can add a force to detect the torque of the motor shaft 14, and one side of the output shaft of the reduction gear box 3 is provided with a torque docking groove 4 for docking and limiting one end of the motor shaft with an external hexagonal surface, and the external hexagonal end of the motor shaft 14 is inserted into the torque docking groove 4 for limiting and fixing, so that there will be no rotation under a large torque;

[0025] Sliding seat 5, the sliding seat 5 is slidably arranged on one side of the end of the machine table 1, and can push and limit the docking with the automatic torque docking groove 4 after docking with the other end of the motor rotating shaft 14. And a torque sensor 6 for slidably docking and limiting with the other end of the motor shaft is installed at the end of the sliding seat 5, which can measure and record the torque value of rotating equipment (such as motors, shafts, gears, etc.) in real time. Through this measurement, the load condition of the equipment during operation can be monitored. By setting a torque threshold, the sensor can trigger an alarm or automatic shutdown to prevent the equipment from being damaged or having an accident due to overload. Usually based on strain gauge technology. The core part of the sensor is a strain gauge that can sense torque changes. When torque is applied, the internal material of the sensor will undergo a small deformation FF0C This deformation will cause a change in the resistance of the strain gauge. The sensor calculates the applied torque by measuring this resistance change, so as to provide a corresponding output signal. And on one side of the sliding seat 5 and on the surface side of the machine table 1, there is a push cylinder part 7 for reciprocatingly moving and limiting and tightly pushing the sliding seat 5, which realizes pushing and feeding the motor rotating shaft 14. A discharge conveyor line 8 for supporting and outputting the discharge after torque detection of the motor shaft is provided through the end of the machine table 1, which realizes the feeding and discharging of the motor rotating shaft 14.

[0026] On one side of the reduction gearbox 3 and on the front and rear sides of the end of the machine table 1, there is a strip-shaped track 9, and the sliding seat 5 reciprocally slides on the strip-shaped track 9 to limit and tightly push the motor shaft. The limit seat 10 is installed at the end of the sliding seat 5, and one end of the torque sensor 6 is provided with a limit cylindrical part 11, and the limit cylindrical part 11 is fixedly penetrated in the limit seat 10. A limit cylindrical groove 12 is opened at one end of the limit cylindrical part 11, and one end of the motor rotating shaft 14 can penetrate into the limit cylindrical groove 12. The limit cylindrical groove 12 is evenly provided with docking limit bumps 13 for limiting and tightly pushing the motor shaft, which plays a role in limiting and fixing one end of the inserted motor rotating shaft 14, and is conducive to discharging the motor shaft after torque detection.

[0027] The motor rotating shaft 14 is docked in the torque docking groove 4 on the output shaft of the reduction gearbox 3 to realize the torque rotation detection of the processed motor shaft. And on the surface of the other end of the motor rotating shaft 14, there are evenly provided docking limit grooves 15 adapted to and docked and limited by the docking limit bumps 13, and one end of the motor rotating shaft 14 can be inserted into the docking limit grooves 15 for limiting and fixing. On both sides of the bottom of the conveyor frame in the discharge conveyor line 8, there are lifting cylinders 16 fixed on the upper ends of the support strip plates provided at the bottom end of the machine table 1, which push the discharge conveyor line 8 to lift and lower to feed and discharge the motor rotating shaft 14. The discharge conveyor line 8 is a conveyor belt for discharging, and a through groove 17 is provided at the position of the discharge conveyor line 8 corresponding to the machine table 1, which is conducive to the lifting feeding and discharging of the motor shaft.

[0028] Specifically, when in use, the motor shaft 14 to be tested is first connected to the unloading conveyor line 8 through an external conveyor line, so that the motor shaft 14 after front-end processing is transported to the conveyor belt on the unloading conveyor line 8, and the motor shaft 14 is transported to the middle position by the unloading conveyor line 8, and the lifting cylinder 16 pushes the unloading conveyor line 8 to move upward through the through slot 17 to the end of the machine 1, so that the two ends of the motor shaft 14 are on the same horizontal line with the torque docking slot 4 and the limit cylindrical slot 12. Then, the push cylinder 7 pushes the sliding seat 5 to slide on the machine table 1 using the strip track 9, so that the limiting cylindrical groove 12 is limitedly sleeved on one end of the motor shaft 14, and the docking limiting protrusion 13 is set to slide into the docking limiting groove 15, so that the docking and fixing of one end of the motor shaft 14 can be carried out, and the position of the motor shaft 14 can be manually adjusted to limit the docking with the limiting cylindrical groove 12, and then the sliding seat 5 continues to move to push the motor shaft 14 to move so that the other end is limitedly docked to the torque docking groove 4 is tightened, the limit docking and fixing of the motor shaft 14 can be achieved. At this time, the lifting cylinder 16 drives the unloading conveyor line 8 to move downward to the initial position. Thereafter, the driving motor 2 rotates to drive the reduction gear box 3 to work, so that the output shaft at the other end drives the motor shaft 14 to rotate with torque to apply torque to the torque sensor 6, so that the internal material of the torque sensor 6 will be slightly deformed, resulting in a change in the resistance of the strain gauge. The torque sensor 6 calculates the applied torque by measuring this resistance change, and the torque detection of the motor shaft 14 can be achieved. After the detection is completed, the pushing cylinder part 7 moves back and disengages from driving the sliding seat 5 to move back, so that the limit cylindrical part 11 can be separated from one end of the motor shaft 14. At the same time, the motor shaft 14 is manually slightly pulled to push the torque docking groove 4. At the same time, the unloading conveyor line 8 supports the motor shaft 14, so that the unloaded motor shaft 14 can be driven by the downward movement of the unloading conveyor line 8, and the unloading output of the motor shaft 14 can be carried out for the next link detection, thereby realizing the unloading and loading of the motor shaft 14.
