Description

Technical Field

[0003] Currently, most solutions rely on detection devices to drive the power, such as the rotation of a drive motor, to calculate displacement and transmit it to the control center. If the motor rotation is effective but the walking mechanism slips and does not produce displacement, the displacement detection will be inaccurate. Electrical displacement sensors cannot function effectively in harsh environments such as high dust levels, affecting the accuracy of automated equipment operation. Utility Model Content

The clamping ball socket support plate 33 is connected to one end of the floating clamping assembly 4. The encoder assembly 5 is installed on the surface of one of the rotary arms 35.

[0031] The floating clamping assembly 4 includes a pressure rod 41, a pressure spring 42, a guide ball head 43, and a locking nut 44. The pressure spring 42 and the guide ball head 43 are both sleeved on the surface of the pressure rod 41. A connecting plate 45 is connected to the surface of the pressure rod 41. The surface of the connecting plate 45 is connected to one end of the pressure spring 42, and the other end of the pressure spring 42 is connected to the surface of the guide ball head 43. The locking nut 44 is threaded onto the surface of the pressure rod 41.

[0032] The guide ball head 43 is provided with a spherical part 6, and the pressing ball socket support plate 33 is provided with a ball socket groove 7. The spherical part 6 of the guide ball head 43 is connected to the ball socket groove 7 of the pressing ball socket support plate 33. The locking nut 44 is provided with an anti-loosening nut 8 on the side away from the guide ball head 43. The anti-loosening nut 8 is threadedly connected to the surface of the pressure rod 41.

The upper spacer 34 and the two rotating arms 35 are connected to the surface of the first mounting pin 22. The inner walls of the two second mating plates 25 are connected to the surface of the second mounting pin 23. The pressure rod 41 is installed on the surface of the second mounting pin 23.

The rotation of the synchronous guide wheel 31's shaft 32 is transmitted to the device via the coupling 53. The encoder feeds back displacement information to the control center. If there is a relative deviation in the time distance of the equipment moving on the guide rail, or if there is a height difference on the guide rail surface, the compression spring 42 effectively presses the guide wheel 31 to always be in contact with the guide rail to transmit motion. The ball head 43 and the ball socket support plate 33 can automatically correct when the compression spring 42 deforms. This device can effectively detect the displacement information of the equipment. The dustproof bearing and bearing dust cover 10 have double sealing, which can meet the requirements of harsh environments such as high dust.
