Abstract
The utility model relates to a centering device which is used on a lathe and in particular relates to a gear type chuck self-centering linkage. The linkage comprises a shell and a shell cover, wherein the shell cover is connected with the shell into a whole, a centre shaft is arranged in the center of the shell cover, a centre shaft bearing is arranged in the centre shaft, a fluted disc is arranged on the centre shaft bearing, a plurality of radial through holes are arranged with equal distance on the lateral face of the shell, splined shafts are traversed through the radial through holes, the inner ends of the splined shafts are connected with bevel gears through the radial bearing, helical teeth on the bevel gears are connected with the helical teeth on the fluted disc, a connection shaft is connected with extended ends of the splined shafts through an adjusting sleeve, the adjusting sleeve is screwed with the splined shafts and the connection shaft, a screwing mode enables the length of the splined shafts and the connection shaft to be adjustable, and the outer end of the connection shaft is provided with a claw feed screw groove. The linkage saves time and labor, and can greatly increase the clamping working efficiency of large scale workpieces, bigger twisting moment can be supported, the durable degree of the design is higher, and the linkage is not easily damaged, the manufacture cost is correspondingly lower, which creates benefits for society.
Description
Technical field
The utility model is the centring means that uses on a kind of lathe, particularly a kind of gear type chuck self-centering linkage.
Background technology
Existing small-sized lathe, its centring means is a three-jaw self-centering chuck, this structure is to adjust one of them claw leading screw, driving other two rhizoid thick sticks by parcel does to be synchronized with the movement along the chuck radial direction and finishes workpiece and clamp, the shortcoming of this structure be bear to clamp moment little, can not be used for finishing clamping of large-scale workpiece, and manufacturing cost is too high, poor durability; The existing large-scale lathe that surpasses the 1000mm diameter, its centring means generally adopts four paws single action structure, this structure is to finish workpiece is clamped by adjusting the claw leading screw one by one, though this structure can firmly clamp large-scale workpiece, but because four paws needs to adjust separately to clamp, so consuming time, effort, operating efficiency are low.
Summary of the invention
The purpose of this utility model is to clamp the defective that the little and four paws centring means adjustment of moment clamps difficulty in order to overcome existing three-jaw centring means, invent a kind of gear type self-centering chuck linkage that bears moment of torsion, realizes chuck self-centering interlock that improves with gear transmission mode, this device safely, reliably can improve the operating efficiency that clamps of large-scale processing parts.
The utility model is to realize by following technical scheme: described gear type self-centering chuck linkage, comprise housing and case lid, case lid and housing are connected in one, and the central authorities of case lid are provided with an axis, axis is provided with bottom bracket bearing, and bottom bracket bearing is provided with fluted disc; The housing side is equally spaced to be provided with a plurality of radial direction through hole, be equipped with splined shaft in the radial direction through hole, the inner of splined shaft is connected with bevel gear by journal bearing, helical teeth on the bevel gear and the helical teeth on the fluted disc join, as long as twist a bevel gear, this bevel gear just can drive remaining bevel gear by fluted disc and rotate synchronously; Connecting axle is adjusted cover and splined shaft and connecting axle and is the mode of being spirally connected by adjusting the extended end that cover is connected splined shaft, and it is adjustable that the mode of being spirally connected makes the length of splined shaft and connecting axle; The outer end of connecting axle is provided with claw leading screw groove.
Described housing side is equally spaced to be provided with a plurality of radial direction through hole, and these a plurality of radial direction through hole can be four, also can be three.
The rear end of described adjustment cover is provided with two symmetrical locking balls.
Good effect of the present utility model is as follows: the utility model saves time, laborsaving, can significantly improve the operating efficiency that large-scale workpiece clamps; Can bear bigger moment of torsion; The durable degree of this design is than higher, and is not fragile; Manufacturing cost is relatively low, is social create beneficial result.

The specific embodiment
Shown in Figure 2 as Fig. 1, described gear type self-centering chuck linkage comprises housing 1 and case lid 2, and case lid 2 is connected in one with housing 1, and the central authorities of case lid 2 are provided with an axis 3, and axis 3 is provided with bottom bracket bearing 4, and bottom bracket bearing 4 is provided with fluted disc 5; Housing 1 side is equally spaced to be provided with four radial direction through hole, be equipped with splined shaft 6 in the radial direction through hole, the inner of splined shaft 6 is connected with bevel gear 8 by journal bearing 7, helical teeth on helical teeth on the bevel gear 8 and the fluted disc 5 joins, as long as twist a bevel gear 8, this bevel gear 8 just can drive its excess-three bevel gear 8 by fluted disc 5 and rotate synchronously; Connecting axle 9 is adjusted cover 10 and is the mode of being spirally connected with splined shaft 6 and connecting axle 10 by adjusting the extended end that cover 10 is connected splined shaft 6, and it is adjustable that the mode of being spirally connected makes the length of splined shaft 5 and connecting axle 9; The outer end of connecting axle 9 is provided with claw leading screw groove 11.What present embodiment constituted is a four paws gear type self-centering chuck linkage.
Described housing side also can equally spacedly be provided with three radial direction through hole, like this what constituted then is a three-jaw gear type self-centering chuck linkage.
The rear end of described adjustment cover 10 is provided with two symmetrical locking balls 12, to guarantee to adjust the correct operating position of cover 10.
During use, four adjustment are placed on link position, when wherein any one adjustment cover makes it to rotate with the specific purpose tool adjustment, by connecting axle, adjustment cover, splined shaft and bevel gear, the rotation of drive fluted disc, make three splined shafts and driving shaft do synchronously, rotate in the same way by other three bevel gears, four claws of drive lathe are done along radial direction and are synchronized with the movement, and finish giving of workpiece and grip dress.When not needing the four paws interlock,, can make any one or several claw leading screw realize rotating separately, to guarantee firmly clamping of out-of-shape workpiece by adjustment is placed on open position.
