Abstract

The utility model relates to a surge mechanism of a conche. Concretely speaking, the utility model is used on all kinds of bearing raceway (channel) and its main function is to convert the rotation motion of the motor to the to-and-fro oscillation of the machine tool. An internal jacket and an external jacket are mainly installed on a mainshaft. The mainshaft is installed in a swing table. A swing rod is installed on the mainshaft and a sliding chute plate is installed at both sides of the swing rod. The front end of the mainshaft is installed in the jacket and is tightly pressed by a rear cover of the swing table; the internal jacket, external jacket and small jacket are installed on an eccentric shaft. The eccentric shaft is installed on a crankshaft seat; on the rear end of the eccentric shaft the bearing and copper sliding block assembled in the trough of the sliding chute. The utility model has simple dense and reasonable structure, is with short manufacture cycle and low cost. The maintenance is convenient, the mechanism is not easy to abrade and the lifetime is long; the surge frequency is high, which reaches 100 times per minute and improves about 40% compared with the traditional structure; the cutting force is large and the production efficiency is high. The processing time of single workpiece can be shortened by 1/3 and the rotation precision of bearing after grinding can be improved.

Description

The oscillating mechanism of lapping machine

Technical field

The utility model relates to a kind of oscillating mechanism of lapping machine, specifically is used for all kinds of raceways (raceway groove) lapping machine, and main effect is the reciprocating vibration that rotatablely moving of motor is directly changed into lathe, belongs to the mechanical structure device technical field.

Background technology

Before the utility model was made, in prior art, the oscillating head mechanism that is used on all kinds of raceways (raceway groove) lapping machine mainly was made up of motor, belt, belt wheel, power transmission shaft, eccentric wheel, bearing, connecting rod and yaw etc.By the driven by motor belt, belt drives belt wheel, and belt wheel drives power transmission shaft, rotates eccentric wheel by power transmission shaft, and eccentric wheel is by the oscillating bearing drivening rod, and connecting rod drives another root power transmission shaft by oscillating bearing, power transmission shaft rotating band movable pendulum head, thus realize vibration.The structure of this kind oscillating mechanism is complicated, and mechanical part is many, the manufacturing cost height; Connecting portion is many, and is fragile, the maintenance cost height; Frequency of oscillation is low, usually can not be greater than 600 times/minute (otherwise lathe can shake, cause and can't work); Cutting output is little, and production efficiency is low, and crudy is difficult to guarantee.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned weak point, thereby provides a kind of simple in structure, the frequency of oscillation height, and cutting force is big, the production efficiency height, and can improve the oscillating mechanism of the lapping machine of raceway (raceway groove) quality behind the lappingout.

Main solution of the present utility model is achieved in that

The utility model mainly adopts bonnet 2 is housed on rack sleeve 1, chuck 4, external jacket 5, clamping ring 11 and bearing 3 on main shaft 8, being equipped with, main shaft 8 rear ends are contained in the rack sleeve 1, back-up ring 6, gland 7 compress before adopting, main shaft 8 is contained in the swing platform 13, and fork 16 is housed on main shaft 8, and coulisse 15 is contained in fork 16 both sides, main shaft 8 front ends are contained in the chuck 19, compress with swing platform bonnet 18; Bearing 3, interior chuck 24, external jacket 25 and clip cover 27 are housed on eccentric shaft 29, and eccentric shaft 29 is installed on the crankshaft base 23, and is fixing with bonnet 26; Eccentric mounting 22 and copper shoe 21 are housed on eccentric shaft 29 rear ends, and eccentric mounting 22 and copper shoe 21 fit in the groove of coulisse 15 mutually.

Compared with the prior art the utility model has the following advantages:

The utility model is simple in structure, compact, reasonable; Manufacturing cycle is short, low cost of manufacture; Easy to maintenance, mechanism is not easy to wear, long service life; The frequency of oscillation height can reach 1000 times/minute, and comparable traditional structure improves about 40%; Cutting force is big, the production efficiency height, and the single-piece work time can shorten 1/3, can improve the running accuracy of lappingout rear bearing.
