He has the workpiece of rotary surface, is in machine-building and repair factory using most wide a kind of machine, at present with it is top position into
All kinds of axis class process equipments of row processing, such as cylindrical grinder, camshaft grinding machine, lathe etc., this kind of equipment is in working shaft-like part
When, machining accuracy such as circularity, bounce etc. is directly influenced by center hole on tailstock and top precision, leads to shaft-like workpiece
The precision processed is low, of poor quality, and the upper tailstock entirety poor air-tightness of current axis class process equipment, reduces tail
The service life of frame, for this purpose, we have proposed a kind of tail stock for machine tool of top rotational structure.
Summary of the invention
The purpose of the present invention is to provide a kind of tail stock for machine tool of top rotational structure, to solve to mention in above-mentioned background technique
Machining accuracy out is directly influenced by center hole on tailstock and top precision, the precision for causing shaft-like workpiece to process
The upper tailstock entirety poor air-tightness of low, of poor quality and current axis class process equipment, reduces the service life of tailstock
Problem.
To achieve the above object, the invention provides the following technical scheme: a kind of tail stock for machine tool of top rotational structure, including
The outer circumferential walls of tailstock spindle, the tailstock spindle are fixed by linear bearing and pedestal installation, and the outer circumferential walls of the tailstock spindle are left
Side is cased with sealing ring, and the top left side of the tailstock spindle, which is bolted, is equipped with end cap, connects between the end cap and pedestal
It is connected to inlet suction port, the left end of the tailstock spindle by swivel bearing and rotates top fixed installation, a left side for the swivel bearing
Side wall is connected with bearing outer ring clamping cap, and the right side wall of the swivel bearing passes through locking nut and holding screw and bearing outer ring
Clamping cap is fixedly mounted, and the outer circumferential walls of the rotary shaft and end cap are socketed with seal closure.
Preferably, the top inside groove of the rotation is conical, and rotates angle formed by top inclined surface and horizontal plane
Degree is 30 to four ten five degree.
Preferably, the right side wall of the left side wall of the inlet suction port and end cap weld, the right side wall of the inlet suction port with
The left side wall of pedestal welds.
Preferably, the sealing ring is shaft block ring.
Preferably, the inlet suction port is made of stainless steel.
Compared with prior art, the beneficial effects of the present invention are: the tail stock for machine tool of this kind of top rotational structure, design are closed
Reason, it is practical, influence of the precision of part center hole and tailstock center to Machining of Shaft-type Parts precision is avoided, part is reduced
Driving moment when processing reduces energy consumption；And the service life of bearing is improved, reduce equipment use cost.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
In figure: 1 rotates top, 2 bearing inner race clamping caps, 3 swivel bearings, 4 bearing outer ring clamping caps, 5 seal closures, 6 ends
Lid, 7 inlet suction ports, 8 pedestals, 9 linear bearings, 10 sealing rings, 11 tailstock spindles, 12 locking nuts, 13 holding screws 13.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Referring to Fig. 1, the present invention provides a kind of technical solution: a kind of tail stock for machine tool of top rotational structure, including tailstock
The outer circumferential walls of axis 11, the tailstock spindle 11 are fixed by linear bearing 9 and the installation of pedestal 8, outside the circumference of the tailstock spindle 11
Sealing ring 10 is cased on the left of wall, the preferred shaft block ring of the sealing ring 10, good airproof performance, rotation is convenient, the tailstock spindle 11
