[background technology]
Known; The grinding and feeding mechanism of centerless grinder adopts the moving tommy bar formula of people usually or adopts worm and gear to drive leading screw and rotate; The moving tommy bar formula of people just rotates feed screw through the handwheel that feed screw is pulled in manual work, thereby obtains coarse feed amount and little amount of feeding of grinding, but the feeding mode of the moving tommy bar formula of this people not only labour intensity is big and during grinding feed accuracy relatively poor; The product size deviation of producing causes defect rate higher greatly; When adopting worm and gear to drive the grinding processing method of leading screw rotation completion, though on labour intensity, alleviate to some extent than the moving tommy bar formula of people, grinding accuracy also increases; But, and can not effectively increase work efficiency because the transmission efficiency of worm and gear is low.
[summary of the invention]
In order to overcome the deficiency in the background technology; The utility model discloses a kind of feed mechanism of centerless grinder; Adopt the feeding of Controlled by Programmable Controller motor driven ball screws, replace moving tommy bar formula of former messenger or worm and gear to drive the feed mechanism that leading screw rotates, thereby realized the auto-feed of centerless grinder; Make machining realize automation, not only reduced labor strength and also improved production efficiency and product quality.
For realizing the purpose of foregoing invention, the utility model adopts following technical scheme:
A kind of feed mechanism of centerless grinder; Comprise ball-screw, screw, sleeve, motor, Programmable Logic Controller, holder and lathe bed; The upper side of said lathe bed is provided with holder, and the upper side of said holder is provided with groove, is respectively equipped with a side arm and another side arm in the both sides of holder upper side; On a side arm and another side arm, be respectively equipped with the through hole of mutual correspondence; Be provided with spacer in the through hole of a said side arm, be provided with screw in the through hole of said another side arm, an end of said ball-screw passes screw and spacer successively; The other end of ball-screw is connected with motor after passing sleeve, bearing, nut and annulus pad successively, and said motor is connected with Programmable Logic Controller through circuit.
The feed mechanism of described centerless grinder is provided with backing plate between lathe bed and holder.
The feed mechanism of described centerless grinder, said ball-screw and spacer are for being slidingly matched.
The feed mechanism of described centerless grinder, the other end of said ball-screw is that key is connected with motor.
The feed mechanism of described centerless grinder is provided with bearing between said sleeve and the ball-screw, and ball-screw and bearing are slidingly matched, and said bearing is fastened in the sleeve through nut and annulus pad.
Owing to adopted technique scheme, the utlity model has following superiority;
The feed mechanism of the described centerless grinder of the utility model; Feeding through the Controlled by Programmable Controller motor driven ball screws; Replace moving tommy bar formula of former messenger or worm and gear to drive the feed mechanism that leading screw rotates; Thereby realized the auto-feed of centerless grinder, made machining realize automation, not only reduced labor strength and also improved production efficiency and product quality; The utlity model has simple in structure, machining accuracy advantages of higher.
