Abstract

The utility model discloses a tilting type numerical control rotary table, aiming at providing the tilting type numerical control rotary table which has compact motion structure and convenient operation and can realize the double-shaft rotary function in a smaller special dimension range. The tilting type numerical control rotary table comprises a servo motor, a cam intermission slicer, an inclined shaft, a base body, a fine adjustment mechanism, and a locking mechanism, etc., wherein, the cam intermission slicer is fixedly arranged on the end face of the inclined shaft, and can adjust any angle aslant and manually; the servo motor is linked with the other end of the inclined shaft and is positioned in a hollow range of the inclined shaft, and drives the output end of the cam intermission slicer to rotate continuously or with a fixed angle. Through using the combination of the cam intermission slicer and a hollow shaft structure, the tilting type numerical control rotary table successfully solves the problem of performing the four-axis or four-axis semi-process on a middle-small numerical control machine tool, realizes the dividing process and the continuous curve surface process of the parts, improves the production efficiency, and lowers the production cost.

Description

The tilting-type NC rotary table

Technical field:

The utility model belongs to machine tool field, mainly is applicable to middle-size and small-size numerical control end mill.

Background technology:

The rotary table product structure complexity that existing Digit Control Machine Tool is adopted, overall dimensions are bigger, are difficult to use on middle-size and small-size lathe, greatly increased production cost.

Summary of the invention:

The purpose of this utility model is to overcome the weak point of existing product, by utilizing the characteristics of cam dispenser, structure in conjunction with hollow shaft, greatly dwindled the physical dimension of NC rotary table, solved easily and on middle-size and small-size Digit Control Machine Tool, carried out four or four semi-finished problems.

The technical solution of the utility model is summarized as follows:

A kind of tilting-type NC rotary table, it is characterized in that it is made up of servomotor, cam indexing separator, sloping shaft, pedestal, micro-adjusting mechanism and retaining mechanism etc., its cam indexing separator is packed on the end face of sloping shaft, in the present body opening of overall co-ordination, manually tiltable is arbitrarily angled then; Servomotor is connected in the other end of sloping shaft and is positioned at the hollow scope of sloping shaft, and the output of its driving cam indexing separator is done continuous or decided the angle rotation.In addition, on rotary table, also be added with the angle of inclination micro-adjusting mechanism and decide the angle retaining mechanism.

The utility model compact conformation, easy to operate, in less bulk scope, realized the twin shaft spinfunction, can be arranged on the table top of middle-size and small-size Digit Control Machine Tool more conveniently, thereby realize calibration processing and continuous curve surface processing to part, reach and reduce cost the purpose of enhancing productivity.

Description of drawings:

Fig. 1, Fig. 2 are structural representations of the present utility model.

Fig. 3 is a practical application schematic diagram of the present utility model.

The specific embodiment:

As accompanying drawing 1, shown in Figure 2, the utility model mainly is made up of servomotor 3, cam indexing separator 7, sloping shaft 6, pedestal 11, micro-adjusting mechanism 1 and retaining mechanism (2,5,10) etc.Cam indexing separator 7 is packed on the end face of sloping shaft 6, then overall co-ordination in the inclination axis hole of pedestal 11, under the situation that locking pressure plate 5 is loosened, manually can be in the limited field of angle banking pin 9 tilt adjustments arbitrarily angled; Servomotor 3 is connected in the other end of sloping shaft 6 and is positioned at the hollow scope of sloping shaft 6, can greatly save the axial dimension space like this, and the output that servomotor 3 is used for driving cam indexing separator 7 is done continuous or decided the angle rotation; In addition, the angle retaining mechanism of deciding of rotary table is to realize by the screw press plate mechanism of both sides, loosens or lock sloping shaft 6 to need only rotational lock nut 10, and the application of force state that changes 5 pairs of sloping shaft flanges of locking pressure plate gets final product; The angle of inclination micro-adjusting mechanism is to adopt the screwfeed mode to reach quantitative feeding, after manually tilting near the required angle, can lock fine setting lock-screw 2, and the rotary fine adjustment handwheel 1 then, according to the indicated value of tuning drive gear 12, accurately locatees the angle of inclination; But sectional fixture clamping workpiece or directly connect workpiece and process on turntable output flange 8, the protective cover of turntable afterbody can protect servomotor 3 not to be subjected to the damage of cooling fluid or smear metal with having.

As shown in Figure 3, the utility model is applied on the miniature numerical control engraving machine, the tilting-type NC rotary table is installed on the work top of lathe with T type screw and hex nut, with the four-jaw chuck clamping workpiece on the turntable output flange, by operation fine setting and retaining mechanism turntable is tilted 45 °, this moment, the feed cutting can be finished the fixedly four-axle linked processing of 45.
