Description
Technical Field
The utility model relates to a compound pendulum jaw breaker support body combination formula installation round pin in the mine, the building materials equipment technical field.
Background
At present, a compound pendulum jaw crusher is common crushing equipment and is mainly used for crushing rocks and ores with various hardness. Along with the upsizing of mines and building material aggregate companies, the requirement on the output of the crusher per hour is higher and higher, so that the crusher gradually develops to be upsized, the structure is more complex, the volume is larger, the working condition and the loading condition are worse, and the requirement on the stability and the reliability of the crusher is higher. The combined type frame body of the existing compound pendulum jaw crusher is usually connected by adopting a cylindrical pin, and the combined type frame body is high in installation accuracy due to the fact that the number of installation pins of the frame body of the crusher is large, and the combined type frame body is extremely difficult and inconvenient to install, disassemble and maintain, and the pins can be installed in place only by heating or cooling parts, so that the process is complex, and the installation cost is high. Therefore, the development of a combined mounting pin for a compound pendulum jaw crusher frame body is a new problem to be solved urgently.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a compound pendulum jaw breaker support body combination formula installation round pin, this utility model designs the installation round pin for the combination formula, with the split of ordinary cylindric lock several part. Only need during the installation with each part combination in proper order and locking, can be with the firm connection of each part of breaker support body, it is very convenient to operate, need not special instrument and technology, also need not to heat or cool off the part, simple structure, installation and dismantlement labour saving and time saving raise the efficiency and reduce cost.
The purpose of the utility model is realized like this: a combined mounting pin for a compound pendulum jaw crusher frame body comprises a bolt, a gasket, an outer pin, an inner pin, a gasket and a nut, wherein the inner pin is arranged in a taper hole of the outer pin, the gasket and the bolt are arranged in the inner pin, the outer pin and the inner pin from the left part of the outer pin and the left part of the inner pin, and the gasket and the nut are fixed with the bolt from the right parts of the outer pin and the inner pin; the inner pin and the outer pin are matched in a conical surface mode, and the outer pin is provided with a through groove.
The main point of the utility model lies in its structure. The working principle is that the inner pin and the outer pin are in conical surface fit. The outer pin is provided with a through groove, and the diameter of the outer cylindrical surface of the outer pin can be expanded when the outer pin is subjected to radial force. The inner pin and the outer pin are in clearance fit with the support body installation pin hole after being combined, after the inner pin and the outer pin are assembled in place, a bolt penetrating through the inner pin is only required to be screwed down, the inner pin and the outer pin can be automatically tensioned in the support body pin hole after being assembled, and the whole crusher support body is firmly connected with all parts after being assembled by more than ten inner pins and outer pins. When the crusher frame body is installed, the combined inner pin and the outer pin are installed in the installation pin holes of the side plates of the crusher frame body and the front and rear frame bodies in a matched mode, the installation bolt penetrates through the installation hole of the inner pin and screws the nut, the inner pin and the outer pin can be automatically tightened in the pin hole in a combined mode, and the side plates of the crusher frame body and the front and rear frame bodies are tightly connected together. The inner pin and the outer pin are matched by conical surfaces. The inner pin and the outer pin 3 are locked by a bolt penetrating through the inner pin.
Compared with the prior art, the combined installation pin for the compound pendulum jaw crusher frame body has the advantages of being simple in structure, convenient to install and disassemble, time-saving and labor-saving, capable of reducing installation and maintenance cost, guaranteeing that each combined pin can guarantee the degree of fit with a pin hole due to the fact that the inner pin and the outer pin are combined to achieve the self-tightening characteristic, achieving tight fitting, guaranteeing the reliability of connection of the frame body, enabling the whole stress of the frame body to be even, improving the safety of equipment operation, stability, reliability and the like, and being widely applied to mines and the technical field of building material machinery.
