Description

Technical Field

[0001] The present invention relates to the technical field of fixtures, and specifically to a rack-type double-drive linkage worm and worm gear reducer running-in clamping device. Background Art

[0002] A worm and worm gear reducer is a power transmission mechanism that uses a gear speed converter to reduce the rotational speed of an electric motor to the required rotational speed and obtain a mechanism with a larger torque. Among the currently used mechanisms for transmitting power and motion, the reducer has a quite wide range of applications. The running-in of a worm and worm gear reducer refers to the process of allowing the worm and worm gear reducer to operate under certain working conditions for a period of time after the new equipment is assembled, so that the surfaces of the mutually cooperating parts gradually reach a good contact and fit state.

[0003] In the running-in operation of a worm and worm gear reducer, a clamping device is needed to fix the worm and worm gear reducer to prevent it from shaking during running-in. Currently, most of the common fixtures on the market use two clamping plates to clamp and fix the worm and worm gear reducer. However, the outer shell of the worm and worm gear reducer is not a smooth plane, and for different models of worm and worm gear reducers, the shapes of their outer shells vary greatly. During the actual clamping process, the contact area between the clamping plate and the outer shell of the reducer is small. When the reducer is connected to power for running-in testing, it is very easy to shake, resulting in poor stability of the running-in process. In view of this, we have developed a rack-type double-drive linkage fixture for the running-in of worm and worm gear reducers. Summary of the Invention

An adjusting component for adjusting the distance between the two slides 11 is provided inside the hollow carrier 1; the adjusting component includes a bidirectional lead screw 14, which is rotatably connected to the middle position inside the hollow carrier 1. The threads at both ends of the bidirectional lead screw 14 are respectively threadedly connected to the two slides 11. A rotating disc 12 is installed on the connecting shaft head at one end of the bidirectional lead screw 14; when it is necessary to adjust the position of the slide 11, the bidirectional lead screw 14 is rotated by rotating the rotating disc 12. The rotation of the bidirectional lead screw 14 can drive the two slides 11 to move correspondingly. The movement of the slide 11 can further adjust the position of the clamping arm 4, and thus the clamping points can be adjusted accordingly according to the shape of the housing of the worm and worm gear reducer.

[0026] On both sides of the upper end face of the slide 11, sliding frames 18 are fixedly connected. Sliding sleeves 17 are fixedly connected to the sliding frames 18.

The clamping arm 4 is slidably connected to the side chute 7. On both sides of the upper end face of the slide 11, sliding seats 19 are fixedly connected. The sliding seats 19 are slidably connected to the clamping arm 4. Driving components for driving the movement of the clamping arms 4 on both sides are provided on the slides 11; during clamping, the driving components drive the racks 16 on both sides to move relative to each other. The movement of the rack 16 can drive the clamping arm 4 to move correspondingly, and thus the clamping action of the worm and worm gear reducer can be achieved.

[0027] The driving assembly includes a vertical shaft 10 which is rotatably connected to the middle position of the sliding table 11 respectively. At the upper end of the vertical shaft 10, a gear 13 is fixedly connected. The two sides of the gear 13 are respectively meshed with the corresponding racks 16.

The spline shaft 9 is slidably connected to the spline sleeve 20. At one end of the hollow carrier 1, a driving motor 5 is provided for driving the spline shaft 9 to rotate; during operation, the driving motor 5 drives the spline shaft 9 to rotate. The rotation of the spline shaft 9 can drive the spline sleeve 20 to rotate. The rotation of the spline sleeve 20 can drive the worm 21 to rotate. The rotation of the worm 21 can drive the worm gear 15 to rotate. The rotation of the worm gear 15 can drive the vertical shaft 10. The rotation of the vertical shaft 10 can drive the gear 13 to rotate. The rotation of the gear 13 can drive the racks 16 on both sides to move relatively or in the opposite direction.

Inside the sliding sleeve 3, an adjusting square rod 23 is slidably connected. At the end of the adjusting square rod 23 away from the sliding sleeve 3, a strip-shaped clamping plate 2 is provided. A pressure sensor 24 is installed between the strip-shaped clamping plate 2 and the adjusting square rod 23. Inside the sliding sleeve 3, an adjusting assembly is also provided for adjusting the extending length of the adjusting square rod 23; the adjusting assembly includes a threaded rod 8 which is threadedly connected to the end of the sliding sleeve 3 away from the adjusting square rod 23. One end of the threaded rod 8 is rotatably connected to the adjusting square rod 23. A handle is fixedly connected to the end of the threaded rod 8 away from the adjusting square rod 23; during use, the threaded rod 8 can be rotated by the handle. The rotation of the threaded rod 8 can drive the adjusting square rod 23 to move correspondingly. The movement of the adjusting square rod 23 can drive the strip-shaped clamping plate 2 to move. Thus, the strip-shaped clamping plate 2 can be adjusted correspondingly according to the shape of the worm and worm gear reducer housing. At the same time, the pressure sensor 24 provided can detect the clamping force. Thus, the clamping force can be controlled according to the need.

[0029] The working principle of the present invention is as follows: When in use, place the worm and worm gear reducer on the hollow carrier 1, and then adjust the position of the clamping arm 4 according to the shape of the outer shell of the worm and worm gear reducer, so that the clamping arm 4 faces the relatively flat position of the outer shell of the worm and worm gear reducer. During the adjustment, rotate the rotating disk 12 to drive the bidirectional lead screw 14 to rotate. The rotation of the bidirectional lead screw 14 can drive the two sliding tables 11 to move correspondingly, and the movement of the sliding tables 11 can further adjust the position of the clamping arm 4. After the adjustment is completed, the drive motor 5 drives the spline shaft 9 to rotate. The rotation of the spline shaft 9 can drive the spline sleeve 20 to rotate. The rotation of the spline sleeve 20 can drive the worm 21 to rotate. The rotation of the worm 21 can drive the worm wheel 15 to rotate. The rotation of the worm wheel 15 can drive the vertical shaft 10. The rotation of the vertical shaft 10 can drive the gear 13 to rotate. The rotation of the gear 13 can drive the two side racks 16 to move relatively. The movement of the racks 16 can drive the clamping arm 4 to move correspondingly, thereby realizing the clamping of the worm and worm gear reducer. When the pressure values of the pressure sensors 24 all reach above the set value, the controller receives the signals from the pressure sensors 24 and controls the drive motor 5 to stop; then adjust the strip-shaped clamping plate 2 according to the shape of the outer shell of the worm and worm gear reducer. During the adjustment, only need to rotate the handle to drive the threaded rod 8 to rotate until the pressures detected by the four pressure sensors 24 are equal, thereby realizing the control of the clamping force of the worm and worm gear reducer and ensuring that the clamping forces at all positions of the worm and worm gear reducer are equal.
