Detailed Description

As shown in fig. 1: the hydraulic control device is characterized in that the base 20 is a base, a driving oil cylinder 1 connected with the hydraulic control device is vertically installed on the base 20, the outer end of a piston rod matched with the driving oil cylinder 1 faces upwards and is in threaded connection with the lower end of the connecting piece 13, the upper end of the connecting piece 13 is inserted into a lower end inserting hole of the pushing rack 3, a pushing spring 2 is arranged between a baffle disc 16 at the lower end of the connecting piece 13 and the lower end face of the pushing rack 3, and the pushing spring 2 is sleeved on the connecting piece 13. The pushing rack 3 is meshed with a gear 4 installed on the base 20, a linear guide rail 7 is arranged on the base 20 in the horizontal direction, the linear guide rail 7 is connected with a sliding table 6, the sliding table 6 is connected with a horizontal rack 5, and the horizontal rack 5 is meshed with the gear 4. The end of the sliding table 6 is connected with a stop iron 12, the stop iron 12 is matched with a limiting body 14 fixed on the base 20, an air detection hole 11 is arranged on the limiting body 14, one end of the air detection hole 11 is sequentially connected with a pressure sensor and an air supply device, and the other end of the air detection hole faces the stop iron 12. The guide sleeve 8 is arranged on the sliding table 6. A limit oil cylinder 9 is vertically arranged on the base 20, the outer end of a piston rod matched with the limit oil cylinder 9 faces upwards and is connected with a wedge 10, a stop block 17 is connected on the sliding table 6, and a combined inclined surface 15 is arranged at the upper ends of the stop block 17 and the wedge 10. The pushing rack 3 is in sliding fit with a rack sliding sleeve 18 fixed on the base 20. The wedge 10 is slidably engaged with a wedge sliding sleeve 19 fixed on the base 20.

The working process is as follows: upwards drive through driving cylinder 1 and promote spring 2, apply for promoting 3 upward movements of rack through the spring force, drive another horizontal rack 5 horizontal motion with gear 4 that promotes 3 meshing of rack, because horizontal rack 5 installs on slip table 6, slip table 6 moves along with horizontal rack 5, take guide pin bushing 8 horizontal motion to the processing position through linear guide 7 direction, spacing hydro-cylinder 9 drives wedge 10 and moves up, wedge slip table 6 through inclined plane 15 that wedge 10 and dog 17 combine, guarantee that slip table 6 and guide pin bushing 8 do not rock during processing. The guide sleeve 8 is pushed to move by the elasticity of the push spring 2, so that the guide sleeve 8 cannot be damaged by rigid collision when the guide sleeve 8 accidentally touches an interference object. Through the gear 4, the pushing rack 3 and the horizontal rack 5, the movement is more stable, and the structure is more compact. After the guide sleeve 8 is in place, the stop iron 12 is attached to the gas detection hole 11 to enable the pneumatic pressure sensor to send a signal, and the in-place position of the guide sleeve 8 is accurate. After the wedge 10 is locked in place, the guide sleeve 8 is ensured to be stable in the machining process, and the machining precision is improved. Compared with the prior feeding device, the device has the advantages of more compact structure, safer and more stable conveying, high position precision and more stable use.
