Description
Technical field
The present invention relates to a kind of auxiliary equipment technical field of horizontal NC lathe, particularly relate to a kind of hydraulic automatic locking device of horizontal NC lathe tailstock.
Background technology
In the prior art, the horizontal NC lathe tailstock all adopts manual locking, namely realize tailstock locking by the screw of tightening on the pressing plate, although such locking mechanism is simple, but it is unreliable to lock, and has increased workman's labour intensity, has reduced production efficiency, if need again locking after simultaneously tailstock moves, owing to the difference of coupling mechanism force causes tailstock and machine tool chief axis to produce the machining accuracy that concentric deviation affects part.
Summary of the invention
The object of the invention is to overcome the defective of above-mentioned prior art, a kind of labour intensity that reduces is provided, enhance productivity, realize horizontal NC lathe tailstock automatic fastening function, improve simultaneously the tail-stock hydraulic-pressure locking device of horizontal digital-control lathe of the working (machining) efficiency of reliable lock and part.
The technical scheme of taking for achieving the above object is: utilize cylinder system and lever principle, change the flow direction of hydraulic oil by the action of system control hydraulic valve, the motion of piston rod realizes the auto lock of tail stock for machine tool, is specially:
A kind of hydraulic automatic locking device of horizontal NC lathe tailstock, comprise tailstock body, it is characterized in that: in the lower space of described tailstock body double rod cylinder is installed, left and right two piston rods of installing in this double rod cylinder can promote respectively its respective side under the oil cylinder hydraulic effect voussoir drives the pull bar that is installed on the voussoir and moves upward, described pull bar lower end links to each other with the pressing plate that compresses lathe bed ways face, and its top is equipped with Compress Spring; Oil pocket in the above-mentioned double rod cylinder links to each other with the hydraulic control system of lathe by hydraulic oil pipe.
The lower end of described pull bar is equipped with spheric washer and nut.
Describedly at tailstock body wear-resistant sleeve is installed.
The hydraulic automatic locking device of horizontal NC lathe tailstock of the present invention is compared with manual locking device of the prior art has following outstanding advantage and result of use:
1. locking is steadily reliable, guarantees machine tool accuracy.
Manual locking is to realize locking by manually tightening bridge screw, and the degree of reliability of locking is determined by human factor, when movable tail frame is locked again again, has also affected the concentricity precision of tailstock and main shaft because of the degree of individual firmly size.And the present invention adopts hydraulic locking apparatus, only need to promote oil cylinder left and right sides piston rod by system's control oil pressure and realize locking with pulling pull bar band dynamic pressure plate, and programming automation control, simple to operate, locking is steadily reliable.
2. improve operating efficiency, reduced labour intensity.
Adopt hydraulic locking apparatus to need not the workman and tighten one by one screw, only need system's control instruction to finish, convenient and time-saving, greatly improved operating efficiency, reduced workman's labour intensity.
3. compact conformation.
Whole hydraulic locking mechanism has only utilized the position, inner space of tailstock body, does not use spanner, the assembly space of the locus when also just need not to consider to use spanner and pressing plate screwing.
In sum, the tail-stock hydraulic-pressure locking device of horizontal digital-control lathe of the present invention need to be applicable to horizontal lathe, the flat lathe bed lathe of tailstock locking, has improved production efficiency, has reduced labour intensity, realize steadily reliably locking, guaranteed the machining accuracy of part.
Description of drawings
Fig. 1 is the structural representation of the hydraulic automatic locking device of horizontal NC lathe tailstock of the present invention;
Fig. 2 be A-A among Fig. 1 to view, B is the locking pipeline among the figure, C is for unclamping pipeline.
The specific embodiment
Below in conjunction with accompanying drawing structure of the present invention is described.
As shown in Figures 1 and 2, the hydraulic locking apparatus of horizontal NC lathe tailstock of the present invention comprises tailstock body 1, double rod cylinder 2 is installed in the lower space of described tailstock body 1, and the oil pocket in this piston rod oil cylinder 2 links to each other by the hydraulic control system of hydraulic oil pipe (11 is straight coupling among the figure) lathe.Left and right two piston rods 5 are installed in this double rod cylinder 2, about two piston rods 5 drive the pull bar 7 that is installed on the voussoir 4 at the voussoir 4 that can promote respectively its respective side under the oil cylinder hydraulic effect and move upward; Described pull bar 7 lower ends are equipped with pressing plate 8, and the top is equipped with Compress Spring 3; Driving above-mentioned pressing plate 8 when pull bar 7 moves upward moves upward and compresses lathe guide pass 12 and (see Fig. 1 with the locking that realizes tailstock 1, the position relationship of A-A view pressing plate 8 and machine tool guideway face 12), and when tailstock 1 need to unclamp, both sides piston rod 5 is regained, but above-mentioned Compress Spring 3 pushing drawing rods 7 move downward, and the pressing plate 8 that compresses lathe guide pass 12 is unclamped; The lower end of pull bar 7 is equipped with spheric washer 9 and nut 10 in addition, and wherein spheric washer 9 is used for preventing stuck phenomenon occurring at pull bar 7 when straining pressing plate 8, and is steadily reliable to guarantee the locking process.At tailstock body 1 wear-resistant sleeve 6 is installed, realizes on the one hand the guiding of pull bar 7, realize on the other hand the convenient maintenance and replacement at position easy to wear herein and do not affect the use of tailstock body.
The main operating process of hydraulic automatic locking device of the present invention is:
One, the pressure required according to part to be processed calculates and will tighten the required oil pressure pressure of tailstock body, and this oil pressure pressure is locked before dispatching from the factory, and the user is forbidden tailstock body oil pressure pressure to be adjusted again after the user family.Control Hydraulic Station to realize locking or to unclamp action by system program.
Two, when hydraulic oil enters oil cylinder by the locking pipeline, promote double piston-rod respectively to two lateral movements, promotion left and right sides voussoir tension pull bar makes it to move upward and is with dynamic pressure plate locking tailstock.Double piston-rod moves downward to intermediary movements Compress Spring while pushing drawing rod respectively and makes the clamp loose that compresses the lathe guide pass when unclamping.
Shortcoming that the present invention had improved in the past because the locking that manual locking brings is unreliable, efficient is low, labour intensity is large, the tailstock precision is wandered away etc., by above solution the manual lock tailstock body bring many unfavorable, realize programming automation control, improved the precision of lathe.
