Automatic press-fitting equipment for elastic pins of hydraulic valves

Abstract

The invention discloses an automatic pressing device for hydraulic-valve elastic pins. The automatic pressing device comprises a second air cylinder, a first hydraulic cylinder, a first supporting ring, a second hydraulic cylinder, a second supporting ring, a front installing plate, an upper installing plate, a right guiding plate, a base plate, a hydraulic power station, a base, a left guiding plate, a back installing plate, a conveying belt, a rodless air cylinder installing frame, a rodless air cylinder, a pneumatic clamping jaw, a third air cylinder, a first air cylinder, a hydraulic valve body, the elastic pins, a right installing plate, a first guiding rod, a first pressing plate, a second horizontal pushing member, a guiding member, a second guiding rod, a second pressing plate, pressing column pins, a third horizontal pushing member and a first horizontal pushing member. The hydraulic valve body is arranged on the conveying belt, the rodless air cylinder and the pneumatic clamping jaw automatically carry out grabbing and carrying in a confederate manner, and the aim that materials are rapidly and automatically fed is achieved; and the elastic pins are more stable in the pressing process, and damage, caused by a labor hammering installing manner, to the elastic pins can be avoided.

Description

technical field [0001] The invention relates to an automatic assembly machine, in particular to an automatic press-fitting equipment for elastic pins of hydraulic valves, which belongs to the technical field of assembly equipment. Background technique [0002] With the continuous expansion of the application of hydraulic technology in the field of mechanical automation, the manufacturing level of hydraulic valves, the control components in hydraulic technology, is also getting higher and higher. When the hydraulic valve is applied in the hydraulic system, it is mainly installed and fixed with screws, but the hydraulic system always has shock and vibration during operation. If the force of the screw directly acts on the hole of the valve body, it will cause the hole to stretch or expand. , if the fit between the hole and the screw becomes loose, the probability of impact and hole damage will be increased, and the inevitable result will be premature failure of the component.

AI Technical Summary

Problems solved by technology

When the hydraulic valve is applied in the hydraulic system, it is mainly installed and fixed with screws, but the hydraulic system always has shock and vibration during operation. If the force of the screw directly acts on the hole of the valve body, it will cause the hole to stretch or expand. , if the fit between the hole and the screw becomes loose, the probability of impact and hole damage will be increased, and the inevitable result will be premature failure of the component. The method to solve this problem is to press the coiled elastic cylindrical pin into the hole. The elasticity of the Coiled Elastic Pin acts as a buffer against vibration and impact. The traditional installation method of the Coiled Elastic Pin is to install it by hammering it by hand. The installation speed is slow, the precision is poor, and the elastic pin is easy to be damaged.
