Abstract
The invention relates to a main shaft cushioning device of a chain slivering machine. The slivering machine comprises a bracket, a main shaft, a transverse beam, an eccentric wheel, a speed reducer, a motor, a transverse beam and an assembling die. The slivering machine is characterized in that one end part of the main shaft is provided with a cushioning device. A fixed support of the cushioning device is fixed on the outer lateral surface of the bracket. The end part of the main shaft is provided with an eccentric cam, and the eccentric cam is sleeved with a brake strap. The fixed support is movably sleeved with a connecting sheet and a leg A of a tripod. The other end of the connecting sheet is connected with one end of the brake strap 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 leans against the eccentric cam. A spring rod is arranged in a straight-through hole of a leg C of the tripod, and one end of the spring rod is connected with the other end of the brake strap through a connecting block. The middle part of the spring rod is sleeved with a spring, and the external threads at the other end of the spring rod are screwed with a spring adjusting nut. By using the main shaft cushioning device, the transverse beam and the die cannot fall down at a high speed when moving downwards, and the main shaft cushioning device cannot generate a serious impact force to a casting die, can greatly reduce the vibration and the noise of the slivering machine, and can greatly improve the assembling speed and the quality of roller chains.
Description
Technical field
The invention 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 invention is to provide 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, can reduce the vibration and the hot-tempered sound of sett frame greatly, can improve the assembling speed and the quality of roller chain greatly casting die.
Technical scheme of the present invention 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.Eccentric wheel and 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.The eccentric cam of buffer unit is installed in main shaft one end.Be 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 invention 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.
Advantage of the present invention has provided 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.
