Abstract
The utility model discloses a fine-tuning feeding mechanism of a grinding machine. The fine-tuning feeding mechanism is characterized in that the fine-tuning feeding mechanism comprises a rapid feeding device, a fine-tuning feeding device and a clutch device, the rapid feeding device comprises a driving hand wheel, a rapid feeding handle is installed on the driving hand wheel, the driving hand wheel is fixedly connected with a driving rod and the driving hand wheel is provided with a connecting end; the fine-tuning feeding device comprises a worm and a worm gear which is engaged with the worm, wherein the worm gear is installed at the connecting end of the driving hand wheel through a bearing; and the clutch device can enable the rapid feeding device and the fine-tuning feeding device to be combined or separated. Since the fine-tuning feeding device with a worm-and-gear mechanism is used for conducting fine feeding adjustment and the adjustment range of the transmission ratio of the worm is wide, the fine feeding can reach 0.1mum and the grinding accuracy of the grinding machine can be improved; and moreover, since the fine-tuning feeding device and the rapid feeding device can be combined or separated through the clutch device, the conversion between rapid feeding and fine feeding is convenient.
Description
Technical field
The utility model relates to a kind of fine setting feed mechanism of grinding machine.
Background technology
The feed mechanism of grinding machine normally adopts servomotor, ball wire bar pair directly to drive the grinder wheel frame at present, because the feed accuracy of traditional feed mechanism is limited, its minimum feeding resolution ratio is 1-0.5 μ m, it is very difficult wanting further to be accurate to 0.2-0.1 μ m, or even impossible, thereby can influence the grinding accuracy of grinding machine.For addressing the above problem, the applicant has developed a kind of fine setting feed mechanism of grinding machine, can make little feeding reach 0.1 μ m by this fine setting feed mechanism, to improve the grinding accuracy of grinding machine.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of fine setting feed mechanism of grinding machine, and little feeding of this fine setting feed mechanism can reach 0.1 μ m, and is convenient to the conversion between fast feed and the little feeding.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of fine setting feed mechanism of grinding machine, it is characterized in that it comprises a quick traverse mechanism, this quick traverse mechanism comprises a transmission handwheel, on this transmission handwheel the fast feed handle is installed, the transmission handwheel is fixedlyed connected with a drive link, and the transmission handwheel has a link; One fine setting feed arrangement, this fine setting feed arrangement comprise that a worm screw reaches and the worm gear of worm engaging, and wherein worm gear is installed in the link of transmission handwheel by bearing; One arrangement of clutch can make quick traverse mechanism and finely tune the feed arrangement combination or separate by this arrangement of clutch.
As the utility model preferred embodiment, described arrangement of clutch comprises that a cannelure and an end that is arranged at the worm gear end is placed in the interior T shape screw of cannelure, the cross section of this cannelure is T-shaped, and T shape screw is through the transmission handwheel, and the one end is equipped with fine setting feeding locking nut.
On the above-mentioned transmission handwheel calibration loop is installed, the worm screw knob is installed on the above-mentioned worm screw.
The beneficial effects of the utility model are: the utility model adopts worm-and-wheel gear fine setting feed arrangement to carry out little feeding adjustment, because the worm-gear drive ratio adjusting range is bigger, therefore little feeding can reach 0.1 μ m, thereby can improve the grinding accuracy of grinding machine; And the fine setting feed arrangement can or separate by the arrangement of clutch combination with quick traverse mechanism, thereby is convenient to the conversion between fast feed and the little feeding.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a schematic perspective view of the present utility model;
Fig. 2 is a cutaway view of the present utility model.
The specific embodiment
With reference to Fig. 1, Fig. 2, the fine setting feed mechanism of the disclosed a kind of grinding machine of the utility model, comprise a quick traverse mechanism, this quick traverse mechanism comprises a transmission handwheel 1, calibration loop 2 is installed on the transmission handwheel 1, fast feed handle 3 is installed on transmission handwheel 1, transmission handwheel 1 is fixedlyed connected with a drive link 4, can drive 1 rotation of transmission handwheel by fast feed handle 3, and then pass through drive link 4 to realize fast feed, as shown in the figure, this transmission handwheel 1 has a link 11, this link and the coaxial setting of drive link, and an end of drive link 4 is fixedlyed connected with link.
One fine setting feed arrangement, this fine setting feed arrangement comprises a worm screw 5 and the worm gear 6 that meshes with worm screw 5, worm gear 6, worm screw 5 is installed in the fine setting holder 7, and the end of worm screw 5 extends to outside the fine setting holder 7, wherein worm gear 5 is installed in the link 11 of transmission handwheel 1 by bearing 8, at link 11 back-up ring 9 is installed, the location that can realize worm gear 5 by this back-up ring 9, be positioned on the worm screw 6 of finely tuning holder 7 outer ends worm screw knob 10 is installed, can drive worm screw by the worm screw knob rotates, and then drive the worm gear rotation, finally by drive link 4 realizing little feeding adjustment, and, what this fine setting feed arrangement adopted is worm-and-wheel gear, because the worm-gear drive ratio adjusting range is bigger, therefore little feeding can reach 0.1 μ m, thereby can improve the grinding accuracy of grinding machine.
One arrangement of clutch can make quick traverse mechanism and finely tune the feed arrangement combination or separate by this arrangement of clutch, thereby is convenient to the conversion between fast feed and the little feeding.
As shown in Figure 2, the arrangement of clutch that present embodiment adopts comprises that one is arranged at the cannelure 61 of worm gear 6 ends and an end and is placed in T shape screw 62 in the cannelure 61, the cross section of this cannelure 61 is T-shaped, T shape screw 62 is through transmission handwheel 1, and the one end is equipped with fine setting feeding locking nut 63.
When unclamping fine setting feeding locking nut, finely tune feed arrangement this moment and separate with quick traverse mechanism, again by fast feed handle drives rotation hand wheel, can be by drive link to realize fast feed; When locking fine setting feeding locking nut, fine setting feed arrangement and quick traverse mechanism combine by T shape screw and fine setting feeding locking nut, and can finely tune feeding by the worm screw knob this moment.
Certainly; the above only is preferred embodiment of the present utility model; can not limit protection domain of the present utility model with it; the utility model also can have other structural change; also can adopt other known structure as arrangement of clutch; and the cross sectional shape of cannelure and the screw terminal shape that is mated screw also can adopt other shape that matches in the above-mentioned embodiment, as trapezoidal shape or the like.So long as the equalization of doing according to protection domain of the present utility model changes and modify, all should still belong in the scope that the utility model contains.
