Abstract

The utility model discloses a differential rolling bar sorter which comprises a feeding system, a body worktable, two motors and two rolling bars. The two rolling bars are symmetrically arranged on the body worktable respectively, a tension wheel and a transmission wheel are arranged at one end of the body worktable, the two motors are vertically arranged on one side of the body worktable, the motor placed on the upper portion of one side of the body worktable is directly connected with one rolling bar through a chain, and the other motor placed on the lower portion of one side of the body worktable is connected with the other rolling bar through the tension wheel, the transmission wheel and a chain. As the speed ratio of the two rolling bars can be optionally adjusted within the speed range of the motors, deflect sorting rate and efficiency can be remarkably increased, and sorting precision can be doubled.

Description

Differential rolling bar grading machine
Technical field
The utility model belongs to mechanical field, is specifically related to a kind of differential rolling bar grading machine.
Background technology
The ball of using for the manufacture of bearing tends to occur the phenomenon that diameter differs in process of production, therefore need to sort out by the ball that same diameter is up-to-standard.At present, the rolling bar grading machines that adopt sort more in the industry.In sorting process, the precision that sorts, to sort efficient and defective elimination factor be the important indicator of weighing rolling bar grading machine performance.Rolling bar grading machine in the industry is to utilize two rolling bars at present, adopts a driven by motor to make their synchronous, synchronized reverse rotations.This rolling bar grading machine is because two rolling bar rotary speeies are consistent, and its problem of bringing is: the one, and low (the ball diameter precision≤0.002mm) of the precision that sorts; The 2nd, efficient is low; The 3rd, defective elimination factor low (≤95%); Bring mass defect therefore can for final bearing products.
Summary of the invention
The purpose of this utility model is to provide a kind of precision height, efficient is high, the defective elimination factor is high differential rolling bar grading machine of sorting.
In order to realize utility model, technical solution adopted in the utility model is as follows:
A kind of differential rolling bar grading machine, it comprises feed system, lathe bed workbench, motor, rolling bar, described rolling bar divides two to be symmetricly set on the lathe bed workbench by bearing block, one end of lathe bed workbench is provided with regulating wheel and drive, have two motors on one side of lathe bed workbench, wherein as for the motor above lathe bed workbench one side directly and a rolling bar wherein be connected by chain, another is connected by chain with another root rolling bar with regulating wheel by drive as for the motor below lathe bed workbench one side.
Above-mentioned differential rolling bar grading machine, described feed system is provided with two single-chip microcomputers;
Above-mentioned differential rolling bar grading machine, described two motors are controlled respectively by two single-chip microcomputers that are arranged on the feed system.
The utility model differential rolling bar grading machine, gravely, two rolling bars adopt two driven by motor, and two motors are independently controlled rotating speed by single-chip microcomputer, thereby can realize that the differential rolling bar sorts.
The utility model differential rolling bar grading machine, its positive meaning is: owing to the speed ratio of two rolling bars can be adjusted arbitrarily in range of motor speeds, so, not only can significantly improve defective elimination factor and efficient, the precision that sorts simultaneously can significantly improve; For the user, the user can set according to every batch of product quality the speed of two rolling bars, thereby can guarantee the higher quality that sorts.
The utility model differential rolling bar grading machine, the applicant has done effective experiment, test, take sort diameter as the ball of 4.763mm as example, existing rolling bar grading machine sorts ball diameter error≤0.002mm, per hour about 10 kilograms of efficient, defective elimination factor about 95%, and employing the utility model; sort ball diameter error≤0.001mm, per hour about 14 kilograms of efficient, defective elimination factor about 99.5%.
Description of drawings
Fig. 1 is the front view of the utility model differential rolling bar grading machine;
Fig. 2 is the top view of the utility model differential rolling bar grading machine;
Fig. 3 is that the A of the utility model differential rolling bar grading machine is to structural representation.
The specific embodiment
Below in conjunction with embodiment the utility model is further elaborated.
Embodiment 1:
As shown in the figure, differential rolling bar grading machine, it comprises feed system 1, lathe bed workbench 2, motor 3, rolling bar 4, two on described rolling bar 4 minutes is symmetricly set on the lathe bed workbench 2 by bearing block, one end of lathe bed workbench 2 is provided with regulating wheel 6 and drive 5, have two motors 3 on one side of lathe bed workbench 2, wherein directly be connected by chain with wherein a rolling bar 4 as for the motor 3 above lathe bed workbench 2 one sides, another passes through drive 5 as for the motor 3 below lathe bed workbench 2 one sides is connected with regulating wheel and is connected by chain with another root rolling bar 4.
As shown in the figure, differential rolling bar grading machine, described two motors 3 are controlled respectively by two single-chip microcomputers 7 that are arranged on the feed system 1.
As shown in the figure, the utility model differential rolling bar grading machine, during work, feed system 1 is sent into ball between two rolling bars 4, and two rolling bars counter-rotate under the effect of motor 3, single-chip microcomputer 7 control rates that motor 3 passes through separately, thus realize that differential sorts ball.
The utility model the utility model differential rolling bar grading machine, owing to the speed ratio of two rolling bars 4 can be adjusted arbitrarily in motor 3 ranges of speeds, so, not only can significantly improve defective elimination factor and efficient, the precision that sorts simultaneously can significantly improve; For the user, the user can set according to every batch of product quality the speed of two rolling bars 4, thereby can guarantee the higher quality that sorts.
