Description
Technical field
The present invention relates to a kind of broaching machine, relate in particular to a kind of a kind of new-type broaching machine of processing the internal and external screw product of various helical pitches and designing.
Background technology
Broaching machine generally is divided into internal broacher and external broaching machine.Internal broacher is used for the broaching inner surface, such as splined hole, square hole etc.Workpiece touch end plate or is placed on the platform, and transmission device is with the broaching tool moving linearly, and picks broaching tool by main cargo chute and auxiliary slide carriage.Internal broacher has horizontal and vertical dividing.The former uses more general, but the machining large workpiece, and floor space is larger; Latter's floor space is less, but broach travel is restricted.External broaching machine is used for surface broaching, mainly contains following several: 1. vertical external broaching machine, and workpiece is fixed on the workbench, and vertically disposed main cargo chute is with broaching tool from top to down broaching workpiece, and floor space is less.2. side broaching machine, horizontal layout, broaching tool is fixed on the edge-on slide carriage, drives drop-down turning work piece at transmission device, is convenient to chip removal, and the outer surface of be applicable to broach large plane, large surplus is such as the large plane of cylinder block and impeller disk tongue-and-groove etc.3. continuous broaching machine, the horizontal layout of more employing is divided into the fixing and broaching tool of workpiece and fixes two classes.The former carries out continuous broaching by one group of broaching tool of chain-driving, is applicable to large-scale workpiece; The latter carries out continuous broaching by a plurality of pallets that workpiece is housed of chain-driving by broaching tool, is applicable to middle-size and small-size workpiece.In addition, also have gear broaching machine, internal thread broaching machine, full-automatic broaching machine, numerical control broaching machine and multitool multistation broaching machine etc.
Along with the kind of spiral product is more and more, quantity is increasing, and quality requirement is more and more higher, and broaching is again that cost is minimum, but the broaching processing request is high, a kind of processing mode that difficulty is large.The method of common broaching spiral product: 1, calculate gear number with horizontal broaching machine according to the workpiece helical pitch; 2, look for change gear; 3, change gear being installed broaches.
Its shortcoming: 1, gears more complicated; 2, the change gear quantity of the various numbers of teeth wants complete; 3, mention that the wheel collocation is cumbersome; 4, the product axiality is poor, and machining accuracy is not high.Existing spiral product processing method can not satisfy processing request, at present domestic also do not have one can accomplish need not machinery more gear changing just can pull out the broaching machine of the internal and external screw product of various helical pitches.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of broaching machine that does not need gear changing more just can pull out the internal and external screw product of various helical pitches.
For solving the problems of the technologies described above, the invention provides following technical scheme: a kind of numerical control hydraulic spiral vertical broaching machine, comprise motor, reductor, workbench, broaching tool, encoder, wherein: install servomotor additional, servomotor drives reductor, and reductor is connected with gear and drives floral disc, and PC is connected and controls the adjustment of helical pitch and rotation direction with servomotor, be arranged on the encoder monitoring broaching tool on the broaching machine, and the broaching tool position signalling is transferred to PC.
As a kind of preferred version of numerical control hydraulic spiral vertical broaching machine of the present invention, wherein: described workbench is hydraulic drive, is provided with approach switch on the broaching machine.
Adopted the broaching machine of technical scheme of the present invention can be fit to produce in enormous quantities and small lot different lead spline broaching; Be applicable to various different lead spline broachings, the precision of the product of broaching simultaneously is high.

Fig. 2 is the lathe bed schematic diagram two of numerical control hydraulic spiral vertical broaching machine of the present invention.
Fig. 3 is the lathe bed schematic diagram three of numerical control hydraulic spiral vertical broaching machine of the present invention.
Fig. 4 is numerical control hydraulic spiral vertical broaching machine anchor clamps schematic diagram of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail.
As shown in the figure, comprising lathe bed 1, floral disc 2, servomotor 3, water pump 4, oil pump 5, control panel 6, electric box 7, system control box 8, water pipe 9, approach switch 10, reductor 11, gear 12, encoder 13.
Principle of the present invention: servomotor 3 control workpiece rotating speed and rotation directions, workbench uses hydraulic drive, and broaching tool pumps, the speed of service and the position of encoder 13 monitoring broaching tools, feedback broaching tool position is to servomotor 3, and servomotor 3 revolves speed adjustment to workpiece again.
Because the helical spline axiality requires high this requirement, at first with the high vertical broaching layout of crudy, the stable hydraulic system of processing, as the basis of design.Design one cover workpiece can rotate the anchor clamps that rotate freely according to servomotor.Servomotor 3 is installed, is added that reductor 11 carries out the active drive rotation, be furnished with two gears 12 as the moment of torsion that transmits, realize the adjustment of any helical pitch and the control of rotation direction with PC control servomotor 3.Consider that workpiece rotating speed and broaching tool broaching speed may be inconsistent, we have adopted again the import encoder that broaching tool is broached position feedback in PC, automatically adjust again the speed of revolving of servomotor by PC, reach broaching helical spline purpose.
As during the helical spline of the A helical pitch of broaching: 1. the helical spline broach of selecting the A helical pitch; 2. input the relevant parameter of A helical pitch at PC; 3. carry out the broaching of helical spline.
When the helical spline of broaching B helical pitch, only need to select the broaching tool of B helical pitch and just can broach at the relevant parameter of PC input B helical pitch.
As when broaching straight spline: select straight spline broach, close servomotor and just can broach the workpiece of straight spline.
This broaching machine processing work precision is high, is fit to the processing of typical products in mass production, also is fit to the processing of different lead be pilot.
It should be noted that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although with reference to preferred embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not breaking away from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
