Abstract
A novel lathe tailstock comprises a sleeve (5) arranged in a tailstock box body (6), a main shaft (4) arranged in the sleeve, and an ejector pin (1) arranged in a taper hole of the main shaft. The main shaft and the sleeve are positioned through a front end tapered roller bearing (3) and a rear end tapered roller bearing (7), wherein the front end tapered roller bearing (3) and the rear end tapered roller bearing (7) are arranged at the two ends of the main shaft respectively. In this way, the rotation main shaft portion of the tailstock is formed and is arranged in the sleeve in a packaged mode through a front end cover (2) and a rear end cover (9). The sleeve is arranged in a left section hole of the tailstock box body. A hydraulic oil cylinder portion is arranged in a right section hole of the tailstock box body. The inner end of a piston rod (10) of the hydraulic oil cylinder portion is connected with the rear end cover in an embedded and sleeved mode, and the inner end of the piston rod is connected with the sleeve through the rear end cover. A limiting sleeve (13) is arranged between the outer section of an outer end oil cylinder cover (12) and the piston rod. According to the novel lathe tailstock, the supporting rigidity of the tailstock and the cutting accuracy of a lathe can be improved.
Description
Technical field
This is practical is newly a kind of device of novel lathe tailstock, the hand tailstock of alternative traditional lathe.
Background technology
What traditional tail stock adopted is hand-rail type, as shown in Figure 1, include thimble 1, barrel of tail stock 14, tailstock casing 6, screw mandrel 15, feed screw nut 16, rear end cap 9, handwheel 17, by rotating handwheel 17, screw mandrel 15 is rotated, and the rotation of screw mandrel 15 makes the barrel of tail stock 14 of lathe do telescopic moving, thimble 1 is housed in the mohs tapered bore on barrel of tail stock 14, thimble 1 telescopic moving together with barrel of tail stock 14, after thimble 1 top tight workpiece, just can carry out the turning processing of workpiece, the tail stock of this structure is not easy to operate when clamping parts, in addition, when workpiece rotates, thimble 1 can not rotate along with workpiece, therefore, between workpiece and thimble, just formed sliding friction, frictional resistance is large, easily heating, high accuracy adds and is difficult to reach requirement man-hour.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, and a kind of novel lathe tailstock is provided.
The purpose of this utility model is achieved through the following technical solutions.
A kind of novel lathe tailstock, include sleeve, the main shaft in sleeve being installed in tailstock casing and be installed on the thimble in spindle taper hole, between main shaft and sleeve, by being installed on respectively nose circle taper roller bearing and the rear end taper roll bearing at main shaft two ends, locate, form thus the rotary main shaft part of tailstock, rotary main shaft part is encapsulated in sleeve by drive end bearing bracket and rear end cap respectively, and sleeve is contained in the left sector hole of tailstock casing; In the right sector hole of tailstock casing, hydraulic jack part is housed, hydraulic jack partly includes hydraulic jack and internal piston bar and outer end oil cylinder cover; Piston rod is inner to be connected with rear end cap is nested, and piston rod the inner is connected with sleeve by rear end cap; Outside the oil cylinder cover of outer end, between section and piston rod, stop collar is also housed.
The utility model makes original hand screw rod feeding mode into hydraulic cylinder feeding, has improved the automaticity of tailstock.Between sleeve and main shaft, add revolving structure, thimble can be rotated together along with workpiece, original workpiece and the sliding friction between thimble are become to the rolling friction of bearing, can improve the rigidity of support of tailstock and the cutting precision of lathe.
Accompanying drawing explanation
Fig. 1 is traditional vehicle tailstock holder structure schematic diagram;
Fig. 2 is the utility model structural representation.
The specific embodiment
As shown in Figure 2, the utility model is on the basis of traditional tail stock, to have added rotary main shaft part and hydraulic jack part.This novel lathe tailstock includes thimble 1, drive end bearing bracket 2, nose circle taper roller bearing 3, main shaft 4, sleeve 5, tailstock casing 6, rear end taper roll bearing 7, nut 8, rear end cap 9, piston rod 10, hydraulic jack 11, oil cylinder cover 12, stop collar 13.Sleeve 5 is installed in tailstock casing 6, and main shaft 4 is installed in sleeve, and thimble 1 is installed in spindle taper hole.Between main shaft 4 and sleeve 5, by being installed on respectively nose circle taper roller bearing 3 and rear end taper roll bearing 7 location at main shaft two ends, form thus the rotary main shaft part of tailstock.Rotary main shaft part is encapsulated in sleeve 5 by drive end bearing bracket 2 and rear end cap 9 respectively, and sleeve 5 is contained in the left sector hole of tailstock casing 6; In the right sector hole of tailstock casing 6, hydraulic jack part is housed, hydraulic jack partly includes hydraulic jack 11 and internal piston bar 10 and outer end oil cylinder cover 12; Piston rod 10 is inner to be connected with rear end cap 9 is nested, and piston rod 10 is inner to be connected with sleeve 5 by rear end cap 9; Between outer section of outer end oil cylinder cover 12 and piston rod 10, stop collar 13 is also housed.
In tailstock when work,, hydraulic oil promotes piston rod 8 and moves, piston rod 8 with moving sleeve 5 with and inner rotary main shaft part do together telescopic moving.During thimble 1 top tight workpiece, the rotation of workpiece, will drive thimble 1, main shaft 4 to rotate together, so just the sliding friction between original thimble and workpiece become to the rolling friction of bearing, just can significantly improve the precision of turning processing parts.In addition, stop collar 13 can regulate the axial stroke of piston rod 8.
