Door closer automatic assembly line

Abstract

The invention discloses an automatic assembly line for door closers, which includes a conveyor belt for conveying the casing, and is characterized in that, along the conveying direction of the conveyor belt, there are arranged in sequence: a three-axis capping machine, which is used to place the left end cap, the lower end The cover and the oil adjusting needle are respectively screwed on the casing; the assembly device is used to install the spring, filter screen, piston, gasket and gear shaft on the casing, and at the same time, the upper end cover and the right end cover are pre-screwed on the On the casing; two-axis capping machine, used to tighten the upper end cap and the right end cap on the casing; oiler, used to add hydraulic oil in the casing, and to detect oil leakage; testing machine, used for Perform a torque test on the assembled door closer. The invention provides an automatic assembly line for door closers, which improves the automation degree of door closer assembly, reduces the degree of manual participation, and improves assembly efficiency.

Description

technical field [0001] The invention relates to an automatic assembly line, in particular to an automatic assembly line for door closers. Background technique [0002] The door closer is a spring-like hydraulic device on the door head. When the door is opened, it can be compressed and released to automatically close the door. It has the function of a spring door and can ensure that the door is closed to the initial position accurately and in time after it is opened. . The significance of the door closer is not only to automatically close the door, but also to protect the door frame and the door body (smooth closing). More importantly, the door closer has become a non-negligible executive part of the intelligent management of modern buildings. Door closers are mainly used in commercial and public buildings, but they are also used in homes. They have many uses, the most important of which is to allow doors to close themselves, to limit the spread of fire and to ventilate bui...

Problems solved by technology

[0003] In the actual production and assembly process, manual installation or door closer assembly machine is used for parts assembly. Both of these methods require manual participation. By manually picking up parts and using tools such as air motors to assemble parts, first, the shell needs to be manually positioned and clamped. Finally, place the end cap, piston, filter, spring, gear shaft and gasket next to the assembly station, manually take out the parts to be installed from the material basket, pre-screw them on the holes and then tighten them with pneumatic tools to complete a After the parts are assembled, it is necessary to remove the next part for assembly. Repeated pick-up is required, and when the parts are placed in the basket, the order of placement needs to be adjusted manually. The production efficiency of the product is low, and it is easy to happen when manual and mechanical interactive production operations safety accidents, potential safety hazards
