Abstract
The utility model discloses a hobbing mandrel capable of simultaneously processing multiple workpieces. A workpiece mounting section is arranged on the hobbing mandrel and is sleeved with at least two workpieces; the workpiece on the outmost side is protruded from the workpiece mounting section by 1-1.5mm along the axial direction. The hobbing mandrel capable of simultaneously processing multiple workpieces can meet a requirement that n workpieces can be hobbed at the same time, so that the processing efficiency is improved; if only one workpiece needs to be processed, a cushion block of which the width is the same as the total width of (n-1) workpieces can be arranged on the side of the workpiece.

Chinese utility model patent CN202344060U relates to a kind of driving gear hobbing device, comprises mandrel, locking nut, space washer, profile of tooth positioning disk, base, pressing plate and plane nut.Mandrel one end is provided with taper shaft and coordinates with base taper hole, is provided with a straight section after taper shaft, and straight section is provided with screw thread, and the space washer matching with gear-hobbing machine is housed, with locking nut, compress, the mandrel other end is Step Shaft, profile of tooth positioning disk by interference fit on mandrel.The utility model is simple in structure, installs easily, and accurate positioning, is specially adapted to existing cone tooth, has again the gear hobbing processing of the driving gear of helical teeth.But this utility model once can only workpiece of clamping, and Gear Processing efficiency is low.
Summary of the invention
The utility model object is to provide a kind of simple in structure, the gear hobbing mandrel that can simultaneously process a plurality of workpiece that Gear Processing efficiency is high.
For achieving the above object, the technical solution adopted in the utility model is: a kind of gear hobbing mandrel that can simultaneously process a plurality of workpiece, which is provided with workpiece construction section, on described workpiece construction section, be arranged with at least 2 workpiece, and outermost workpiece protrudes from described workpiece construction section 1 ~ 1.5mm vertically.By said structure, thereby gear hobbing mandrel meets the requirement of n workpiece gear hobbing simultaneously, improves working (machining) efficiency; If only need to process a workpiece, the cushion block wide with (n-1) individual workpiece can be set in its side.
On the above-mentioned gear hobbing mandrel that can simultaneously process a plurality of workpiece, be also provided with conical section, a side away from described conical section of described workpiece construction section is provided with positioning threads section, and the workpiece being sheathed on described workpiece construction section is tightly fixed on described gear hobbing mandrel by pad and the nut clip of being located in this positioning threads section.
In technique scheme, between described workpiece construction section and positioning threads section, be provided with location escape, and described positioning threads section and the location end chamfer that is connected of escape.
Preferably, interference fit between described workpiece and workpiece construction section, the magnitude of interference is 0.005 ~ 0.295mm.
In technique scheme, the side away from described workpiece construction section of described conical section is provided with spacing thread segment, between described conical section and spacing thread segment, is provided with spacing escape, and 45° angle is fallen in the end that is connected with spacing escape of described spacing thread segment.
In technique scheme, described conical section is Morse's taper section, and its taper angle is 19.002 °, and precision is high, can bear torque.
In technique scheme, 45° angle falls in the end that described conical section is connected with spacing escape.
Because technique scheme is used, the advantage that the utility model compared with prior art has is:
1. the utility model meets the requirement of n workpiece gear hobbing simultaneously, improves working (machining) efficiency; If only need to process a workpiece, the cushion block wide with (n-1) individual workpiece can be set in its side.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment mono-;
Fig. 2 is the partial enlarged drawing at A place in Fig. 1;
Fig. 3 is the partial enlarged drawing at B place in Fig. 1;
Wherein: 1, conical section; 2, workpiece construction section; 3, spacing thread segment; 4, spacing escape; 5, workpiece; 6, positioning threads section; 7, pad; 8, nut; 9, location escape.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment mono-: shown in Fig. 1 ~ 3, a kind of gear hobbing mandrel that can simultaneously process a plurality of workpiece, which is provided with conical section 1 and workpiece construction section 2, on described workpiece construction section 2, be arranged with at least 2 workpiece 5, and outermost workpiece 5 protrudes from approximately 1 ~ 1.5mm of described workpiece construction section 2 vertically.
In the present embodiment, on described workpiece construction section 2, interference fit has 2 workpiece 5, and the magnitude of interference is 0.005 ~ 0.295mm, and the workpiece 5 in outside protrudes from approximately 1 ~ 1.5mm of described workpiece construction section 2 vertically.
A side away from described conical section 1 of described workpiece construction section 2 is provided with positioning threads section 6, and the workpiece 5 being sheathed on described workpiece construction section 2 is fixedly clamped on described gear hobbing mandrel by pad 7 and the nut 8 of being located in this positioning threads section 6.
Between described workpiece construction section 2 and positioning threads section 6, be provided with location escape 9, and described positioning threads section 6 with locate end that escape 9 is connected and fall 45° angle.
Described conical section 1 is Morse's taper section, and its taper angle is 19.002 °.A side away from described workpiece construction section 2 of described conical section 1 is provided with spacing thread segment 3, is provided with spacing escape 4 between described conical section 1 and spacing thread segment 3, and 45° angle is fallen in the end that is connected with spacing escape 4 of described spacing thread segment 3.45° angle falls in the end that described conical section 1 is connected with spacing escape 4.By said structure, gear hobbing mandrel is easy to process, avoids the stress of the junction of spacing thread segment and conical section to concentrate, and gear hobbing mandrel intensity is good, improves gear hobbing precision.
