Automatic assembling device for piston in manual pump

Abstract

The invention relates to an automatic assembling device for a piston in a manual pump, and belongs to the field of mechanical manufacturing. A feeding device is connected with a rodless air cylinder, and the feeding device and the rodless air cylinder are fixed to a mounting plate on the right side of a main frame; the manual pump is initially positioned by a U-shaped limiting block on one side of a manual pump valve body and then is clamped by devices such as a clamping block and a clamping plate which are located on the two sides of the manual pump valve body; and an air cylinder provides power. An opening and closing type pneumatic grabbing part is used for grabbing a piston rod, and the air cylinder located on the upper portion of the opening and closing type pneumatic grabbing part provides power; the air cylinder is mounted on an L-shaped mounting plate, and the L-shaped mounting plate is driven by the rodless air cylinder located on a whole frame, so that pushing work of the piston rod is achieved; and a limiting block connected with the rodless air cylinder positions the precise mounting position of the piston rod. The automatic assembling device has the beneficial effects that the structure is novel, reliability and practicability are achieved, the automation degree is high, and the assembling process is reliable and stable; and the device can be directly applied to an automation assembling production line, and the labor cost is reduced.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a device for automatic assembly of piston rods in manual pumps. Background technique [0002] Hand pumps are important components in heavy-duty vehicles and construction machinery, providing hydraulic oil with a certain pressure for hydraulic actuators. The assembly of the manual pump is very cumbersome and involves many parts. Assembling the piston rod is a key process in many manual pump assembly processes. Because this process needs to accurately install the piston rod in the valve body of the manual pump, the positioning is required to be very accurate. Because it is difficult to realize automatic installation, most of the assembly is currently still Manual assembly, low production efficiency, high labor costs, poor assembly process stability, and poor assembly accuracy. Needs to be improved. Contents of the invention [0003] The object of the present invention i...
