Background technology
As everyone knows, along with the development of society, for modern numerically controlled tooth grinding machine bed, machining accuracy and alleviate aspect the adjustment personnel working strength require increasingly high.When the high fine finishining of roll flute, the tailstock centre of gyration and work table rotation center axiality require high.If coaxiality error is bigger, directly influence the accuracy of gear of processing work.Traditional tail stock for machine tool does not have guiding mechanism, can only fix with alignment pin through big installed surface of reconditioning rear column again.Guarantee the tailstock center centre of gyration and work table rotation centres.But because lathe inevitably can be lost precision in the process of processing in enormous quantities, traditional mode must be taken out the alignment pin of big installation of rear column and unclamped hold-down screw, proofreaies and correct the revolution geometric accuracy of tailstock again, wastes time and energy.
In sum, existingly can't not satisfy high-precision now, the requirement of grinding machine bed efficiently with the tailstock form of guiding mechanism.
Summary of the invention
The purpose of the utility model is can't not satisfy high-precision now, the present situation of the requirement of grinding machine bed efficiently with the tailstock of guiding mechanism to existing, through partly increase a kind of tailstock structure with top centre of gyration Precision trimming function of simple in structure, revolution geometric accuracy that can fast precise adjustment tailstock at tailstock.。
The technical scheme of the utility model is:
A kind of gear grinding machines tailstock with centre of gyration Precision trimming function; It comprises Connection Block 6 and tailstock 2, and Connection Block 6 is connected with rear column guide rail slide unit, and tailstock center 4 is fixed on the tail spindle 3 through No. 4 taperings of Mohs; Two groups of bearing fixing are passed through in the endoporus of tailstock 2 in tail spindle 3 two ends; The described tailstock of its characteristic 2 upper ends are equipped with top board 1, and the lower end is equipped with lower platen 9, are separately installed with the corresponding iron 7 of stopping between 6 contacted of tailstock 2 and the Connection Blocks; 8; Be vertically installed with the bolt 11 of some groups of butterfly springs 13 tensions on tailstock 2 oblique angle relative with Connection Block, bolt 11 is fixed on tailstock 2 on the iron 7,8 of stopping on two sides being close to Connection Block 6 through spring force firmly; The contact-making surface of iron 7,8 and Connection Block 6 stopped is the inclined-plane, the iron 7 of stopping; 8 two ends up and down are respectively through two adjustment screws 5; 10 are fixed on top board 1 and the lower platen 9, and adjustment screw 5,10 moves the centre of gyration of corresponding the stop iron 7 or the iron 8 Precision trimming tailstock centers 4 of stopping.
The described contact-making surface of stopping iron 7,8 and Connection Block 6 is the inclined-plane of 1:100.
The adjustment pad 12 of adjustment tightening force size is installed in the mount pad of described butterfly spring 13.
Described tailstock 2 oblique angles relative with Connection Block are 45 °.
The beneficial effect of the utility model:
The centre of gyration of the tailstock center 4 of the utility model can Precision trimming.Need not become flexible big mounting screw of rear column, can proofread and correct the centre of gyration fast accurately.
The utility model is simple in structure, and is easy to adjust, helps improving the machining accuracy of gear grinding machines, alleviates operating personnel's adjustment difficulty, improves adjustment efficient, improves work efficiency.
Description of drawings
Fig. 1 is the sectional structure sketch map of the utility model.
Fig. 2 is the plan structure sketch map of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Like Fig. 1, shown in 2.
A kind of gear grinding machines tailstock with centre of gyration Precision trimming function, it comprises Connection Block 6 and tailstock 2, Connection Block 6 is used for being connected with gear grinding machines rear column guide rail slide unit; Tailstock 2 all is miter angle with Connection Block 6 corresponding corners, and as shown in Figure 2, tailstock center 4 is fixed on the tail spindle 3 through No. 4 taperings of Mohs; In the endoporus of tailstock 2, tailstock 2 upper ends are equipped with top board 1 through two groups of bearing fixing at tail spindle 3 two ends, and the lower end is equipped with lower platen 9; Be separately installed with the corresponding iron 7,8 of stopping between 6 contacted of tailstock 2 and the Connection Blocks; Stop 6 contacted of iron 7,8 and Connection Blocks is the inclined-plane, and the slope on inclined-plane can be 1:100, so that the center of adjustment tailstock 2; The tailstock 2 45 ° oblique angles relative with Connection Block (also can be the oblique angle of other angle; Be the best wherein with 45 degree) on be vertically installed with some groups (be preferably three groups, wherein two ends be respectively one group, middle one group; Also can be up and down each one group or four groups and more than) bolt 11 of butterfly spring 13 tensions; Bolt 11 is fixed on tailstock 2 on the iron 7,8 of stopping on two sides being close to Connection Block 6 through spring force firmly, and the big I of spring force is adjusted through in the mount pad of butterfly spring 13, installing adjustment pad 12 additional; Stop iron 7,8 two ends up and down respectively through two the adjustment screws 5; 10 are fixed on top board 1 and the lower platen 9; Adjustment screw 5 or 10 can make the iron 7 of stopping (iron 8 of stopping) move up or down; Effect through spring force is moved the center line of tailstock 2 then, realizes the purpose of the centre of gyration of Precision trimming tailstock center 4.
