Abstract
The invention discloses a hobbing clamp relating to the technical field of manufacture of machining equipment. The hobbing clamp comprises a main mandrel, wherein one section of thread is arranged at the upper end of the main mandrel, a nut is sleeved on the thread, an auxiliary mandrel is sleeved outside the main mandrel, an inner hole of the auxiliary mandrel is in clearance fit with the main mandrel, and a cushion cover is arranged on at least upper end of the main mandrel. Compared with the prior art, the hobbing clamp has the advantage that the problems of poor generality, high production cost and low gear hobbing production efficiency of the existing hobbing clamp can be solved.
Description
Technical field
The present invention relates to machining equipment manufacturing technology field, especially a kind of for carrying out the technological equipment of gear hobbing on gear-hobbing machine.
Background technology
Gear-hobbing machine is a kind of in gear cutting machine, with gear-hobbing machine, the sleeve workpiece as gear is carried out gear hobbing and adds man-hour, mostly adopts a kind of gear-hobbing clamp is carried out clamping to gear to fix; This gear-hobbing clamp comprises that an end is provided with the mandrel of positioning table, and the other end of this mandrel is provided with one section thread spindle, is coated with nut outside described thread spindle.During clamping, first mandrel was installed bore, a side end face of gear and the upper surface of positioning table are connected, and by the nut on the threaded together axle, gear was carried out clamping and fix; Then the lower end of main mandrel is clamped by the base assembly that is contained on workbench, then carry out gear hobbing after with the gear-hobbing machine tailstock centre, the upper end centre hole of mandrel being held out against and process.In use there is following deficiency in this gear-hobbing clamp: this gear-hobbing clamp versatility is poor, the gear of processing different endoporus will be equipped with the different mandrels that matches with the endoporus of gear that is provided with, and this mandrel need forge, and the production cycle is long, workload is large, cost is also high, if the endoporus of gear strengthens, the mandrel that matches with it also strengthens thereupon, and then cost is higher, cause production efficiency low, the delivery cycle is long, and production cost is high.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of gear-hobbing clamp, and this gear-hobbing clamp is used existing gear-hobbing clamp to greatest extent, and secondary mandrel gets final product through modifier treatment with bar.It is poor that the present invention can solve existing gear-hobbing clamp versatility, production cost height and the low problem of gear teeth production efficiency.
In order to address the above problem, technical scheme of the present invention is: comprise that the upper end is provided with the main mandrel of one section screw thread, be set with nut on described screw thread, be set with secondary mandrel outside described main mandrel.
In above-mentioned gear-hobbing clamp technical scheme, more specifically scheme can also be: the endoporus of described secondary mandrel and described main mandrel are matched in clearance.
Further: described main mandrel is provided with cushion cover in the upper end at least.
Further: described main mandrel lower end is provided with step.
Owing to adopting technique scheme, the present invention has following beneficial effect:
1, simple structure of the present invention, in processing is different, the hole dimension gear can utilize existing mandrel, changes different secondary mandrels and gets final product, and should the pair mandrel need not forge with bar and get final product through modifier treatment, highly versatile, applied widely and processing cost is low, production efficiency is high, and the delivery cycle shortens;
2, because the endoporus of secondary mandrel and main mandrel are bordering on zero location, gap and coordinate for reserving the matched in clearance after allowance for finish and choosing minimum clearance, can satisfy the industry 6 class precision Gear Processing requirements such as Digit Control Machine Tool, machining accuracy is high, has improved simultaneously production efficiency.

The specific embodiment
The present invention is further described below in conjunction with drawings and Examples:
Embodiment 1:
Gear-hobbing clamp as shown in Figure 1 includes main mandrel 1, main mandrel 1 upper end is provided with one section screw thread, be set with secondary mandrel 4 outside main mandrel 1, endoporus and the main mandrel 1 of secondary mandrel 4 are matched in clearance, when clamping needs the workpiece 3 of gear hobbing, the main mandrel 1 that is set with secondary mandrel 4 is penetrated workpiece 3 endoporus, and cover loading nut 2 on main mandrel 1 threaded shaft section is fitted on supporting seat 5 after secondary mandrel 4 and workpiece 3 matched in clearance.
Embodiment 2:
The present embodiment is set with cushion cover 6 in main mandrel 1 upper end between nut 2 and workpiece 3; Other features are identical with embodiment 1.
Embodiment 3:
The present embodiment is set with cushion cover 6 in main mandrel 1 upper end between nut 2 and workpiece 3; Be set with cushion cover 7 between main mandrel 1 lower end workpiece 3 and supporting seat 5; Other features are identical with embodiment 1.
Embodiment 4:
The present embodiment master mandrel 1 lower end is provided with step 1-1; Be fitted on step 1-1 after secondary mandrel 4 and workpiece 3 matched in clearance; Be set with cushion cover 6 in main mandrel 1 upper end between nut 2 and workpiece 3; Other features are identical with embodiment 1.
Embodiment 5:
Be set with cushion cover 7 between the present embodiment master mandrel 1 lower end step 1-1 and workpiece 3; Other features are identical with embodiment 4.
The selected matched in clearance of above-described embodiment is the fit tolerance corresponding with workpiece after the reservation allowance for finish, therefore can satisfy the industry 6 class precision Gear Processing requirements such as Digit Control Machine Tool.
During clamping, first with secondary mandrel
4Be sleeved on main mandrel 1, then workpiece 3 that will gear hobbing is sleeved on secondary mandrel
4On, then the lower end with main mandrel 1 clamps by the base assembly 5 that is contained on workbench, withstand with the centre hole of gear-hobbing machine tailstock centre with the thread spindle upper end of main mandrel 1 again, proofreading and correct main mandrel 1 upper end periphery, excircle of workpiece cylinder, workpiece upper surface beats in 0.05, top tight workpiece carries out gear hobbing processing afterwards to workpiece 3.Processing different size endoporus gear can utilize existing mandrel 1, and changes different secondary mandrels 4 and get final product, highly versatile, applied widely and processing cost is low, production efficiency is high, the delivery cycle shortening.
