Abstract
The utility model relates to a cushioning device used for a main shaft of a chain slivering machine. The chain slivering machine comprises a support, a main shaft, a cross beam I, an eccentric wheel, a speed reducer, a motor, a cross beam II and an assembly die; the chain slivering machine is characterized in that a cushioning device is installed at one end of the main shaft; a fixed fulcrum of the cushioning device is fixed on the outer side surface of the support; an eccentric cam is installed at the end part of the main shaft, and a brake band is sleeved on the eccentric cam; a connecting piece and a leg A of a tripod are respectively and movably sleeved at the fixed fulcrum; the other end of the connecting piece is connected with one end of the brake band through a pin shaft B; a leg B of the tripod is connected with a tension wheel through a pin shaft A, and the tension wheel is connected with the eccentric cam in a propped manner; a spring rod is installed in a straight-through hole of a leg C, and one end of the spring rod is connected with the other end of the brake band through a connecting block; and a spring is sleeved in the middle of the spring rod, and a spring adjusting nut is rotatably installed on an external thread at the other end of the spring rod. When moving downwards, the cross beams and the die do not sharply fall off to cause no serious impact force to the casting die, therefore, the cushioning device can greatly reduce the vibration and noise of the chain slivering machine and greatly improve the assembly speed and quality of the roller chain.
Description
Technical field
The utility model belongs to roller chain assembly machine technical field, particularly a kind of main shaft cushioning device of chain slivering machine.
Background technology
The chain slivering machine slivering speed of using is fast at present, and it is unreasonable to reach certain structures always by this press proof formula of what, and many local easy break-downs easily cause shutdown.This will have a strong impact on the assembling speed and the quality of roller chain.In chain slivering process, to the friction and the impact of casting die, the roller chain sett frame all adopts at main-axis end opening obvolvent buffer unit is set when falling for reducing crossbeam.The shortcoming of sort buffer device is: friction that produces when crossbeam and mould move up and down and cushion effect be size equally, and this has increased the living load of motor.The gap of transmitting gear and generation thereof when crossbeam and mould move downward,, can hang downwards rapidly when arriving at casting die, owing to can produce big impact thereby produce vibration and hot-tempered sound because of reasons such as its deadweights.
Summary of the invention
The purpose of this utility model provides a kind of main shaft cushioning device of chain slivering machine, when this device moves downward crossbeam and mould, can not hang downwards rapidly, can not produce serious impact to casting die, the vibration and the hot-tempered sound of sett frame can be reduced greatly, the assembling speed and the quality of roller chain can be improved greatly.
The technical solution of the utility model is: a kind of main shaft cushioning device of chain slivering machine.This sett frame is that main shaft and crossbeam are housed on the sett frame support.Eccentric wheel is housed on the main shaft.Main shaft also is connected with motor by deceleration device.The assembling mould is housed on the crossbeam.An eccentric wheel and an assembling mould cooperate to be installed.Be characterized in: buffer unit is equipped with in main shaft one end.The fixed pivot of buffer unit is fixed on the support lateral surface.Spindle nose is equipped with eccentric cam, is set with brake ribbon on the eccentric cam.Be movably installed with the A pin of brace and tripod on the fixed pivot.The brace other end is connected with an end of brake ribbon by bearing pin B.The B pin of tripod is connected with regulating wheel by bearing pin A, and regulating wheel is abutted against mutually with eccentric cam.In the clear opening of the C pin of tripod spring lever is housed, spring lever one end is connected with the other end of brake ribbon by contiguous block.The spring lever intermediate sleeve is equipped with spring, is installed with the spring adjusting nut on the external screw thread of the spring lever other end.
The course of work of the present utility model and principle are: main shaft rotates under driven by motor, drives crossbeam by eccentric wheel when main shaft rotates and assembles the slivering action that mould moves up and down and realizes roller chain.When spindle eccentric wheel drive crossbeam was up, the eccentric cam face reduced to smallest point by portion, and the frictional force that produce between brake ribbon and the eccentric cam this moment is for minimum.Otherwise when spindle eccentric wheel drive crossbeam was descending, the eccentric cam face expanded maximum point to by portion, and the frictional force that produce between brake ribbon and the eccentric cam this moment is for maximum.In view of the above as can be known, when crossbeam moves downward with the assembling mould, this buffer unit produces eccentric by the eccentric cam that is installed in spindle end, eccentric cam promotes regulating wheel and makes the continuous tensioning of brake ribbon, make after the brake ribbon tensioning between brake ribbon and the eccentric cam to produce big frictional force, it is slowly descending that main shaft rotates the crossbeam and the die device that make chain slivering machine of slowing down.The frictional force that produces between brake ribbon and the eccentric cam when crossbeam and die device arrive near workpiece is for maximum.So just can eliminate the gap between the transmission middle gear, to the impact of casting die, just can reduce vibration and hot-tempered sound in the transmission greatly in the time of just reducing sett frame crossbeam and mould whereabouts greatly, just can not influence the assembling speed and the quality of roller chain.
The utility model has the advantages that provides a kind of main shaft cushioning device of chain slivering machine, when this device moves downward crossbeam and mould, can not hang downwards rapidly, can not produce serious impact to casting die, the vibration and the hot-tempered sound of sett frame can be reduced greatly, the assembling speed and the quality of roller chain can be improved greatly.
