Bearing bush two-sided chamfering machine with automatic feeding and discharging function and use method thereof

Abstract

The invention relates to a bearing bush two-sided chamfering machine with an automatic feeding and discharging function, and a use method thereof. According to the invention, a pushing device, a blanking groove, a material feeding conveying device, a stirring platform, a retaining cylinder block and an allocation cylinder are arranged on an original machine tool, so that bearing bush blank can be fallen onto the bottom of the blanking groove in pairs and can be pushed into a station moulding bed by the pushing device; the bearing bush blank rotates along with the station moulding bed and is pushed out by the pushing device after being processed by a compressing device and a two-end-face processing device, so that an automatic circulating continuous processing production line is formed. The bearing bush two-sided chamfering machine with the automatic feeding and discharging function is simple in structure, high in automation degree, high in processing efficiency, high in machining precision and low in labor strength; meanwhile, the chamfering machine is simple in use method and operation, and the whole machining process is highly harmonious and unified and is high in security.

Description

technical field [0001] The invention relates to a bearing bush processing equipment and a use method thereof, in particular to a bearing bush double-sided chamfering machine with automatic loading and unloading functions and a use method thereof. Background technique [0002] Bearing bush is a mechanical element used to support shaft parts and make the bearing surfaces slide relative to each other. As a key basic component, it is widely used in large equipment such as machine tools, generators, electric motors, internal combustion engines, steel rolling machinery, and mining machinery; The bearing pad is one of the key components in the engine motion system. Its structure is simple, but the processing procedure is complicated and the processing process is long. During the processing of the bearing pad, machining the two ends of the bearing pad is one of the important steps; the existing processing method is Cut the raw material of the metal sheet to the required length, then...

Problems solved by technology

After nearly 20 years of development, my country's chamfering machine has gradually transitioned from the low-tech level of a single model to the direction of multiple models. However, there is a large gap between the overall control level and accuracy compared with foreign countries, and it is difficult to meet the requirements in production. , especially the chamfer size does not meet the requirements of international standards

Although many domestic bar or wire companies have an urgent demand for chamfering equipment, the price of imported equipment is very high, and the technology of the servo control system used is kept secret, which brings great inconvenience to users for product updates and equipment maintenance.

[0004] In China, the traditional manual bearing pad chamfering machine adopts the operation process for processing both ends of the stamped bearing pad, such as figure 1 As shown, in the area to be processed, two semicircular bearing bushes are manually taken to form a complete circle, and the matched product is put into the tire mold of the station and patted tightly. , manually take out the products in the tire mold of the station and restore the arrangement, and put the processed bearing bushes into the finished product box. This processing method has the disadvantages of low production efficiency and high labor intensity, and every time several sets of bearing bushes are processed, the motor needs a Stopping on and off not only wastes energy, but also reduces the service life of the motor

[0005] In recent years, the double-sided chamfering machine for bearing pads is mainly used for section chamfering and edge trimming of thin-walled bearing pads. It is a special machine tool for bearing pad chamfering and edge trimming. A series of advantages such as uniformity on the circumference have been recognized by the user Pugao. However, due to the semi-automatic operation of the ordinary bearing double-sided chamfering machine, the labor intensity of the actual operation is high, and the manual operation on the rotating disc is unsafe. Semi-automatic It is difficult for the operation to have free time to increase the frequency of self-inspection of product quality, so it has become a technology in the art to develop a bearing chamfering machine with high automation, continuous production, high processing efficiency, safe operation, low labor intensity and low energy consumption. Issues that need to be resolved urgently
