Abstract
The utility model relates to a positioning structure for an indexing worm of a large-scale numerical control gear hobbing machine, which is especially applicable to the technical field of large-scale numerical control gear hobbing machining machine tools. The positioning structure is as follows: an indexing worm shaft is installed on a worm rack, a bearing is arranged between the end of the worm shaft and the rack, and the ends of the bearing are provided with lock nuts playing the role of fixation. The bearing arranged between the left end of the worm shaft and the rack is a rolling bearing, and the bearing arranged between the right end of the worm shaft and the rack is a needle bearing. Due to the adoption of a large-angle thrust angular contact ball bearing and a high-accuracy needle bearing, the positioning structure has the effects of radial positioning, high bearing capacity and high positioning accuracy, and can ensure that the vibration of an operating platform acted by large cutting force can be effectively prevented when large and heavy-duty gears are machined by the machine tool, thereby increasing the grade of machining accuracy of the gears and optimizing the indexing transmission structure of the operating platform of the numerical control gear hobbing machine.
Description
Affiliated field
The utility model belongs to the heavy-duty gear machine industry, is particularly useful for the technical field of large-sized numerical control gear hobbing machining tool, is mainly a kind of large-sized numerical control gear-hobbing machine indexing worm location structure.
Background technology
Prior art to the large-sized numerical control gear-hobbing machine processing use in, the gear-hobbing machine indexing worm location structure technical finesse means and the mode that are adopted, it is normal because processing work weight is heavier, diameter of work is bigger, make processing during this type of part indexing accuracy cannot say for sure card, and the fixed engagement of indexing worm and dividing worm wheel is the key of guarantee Gear Processing precision.
Summary of the invention
The purpose of this utility model is at deficiency of the prior art, proposes a kind of large-sized numerical control gear-hobbing machine indexing worm location structure that is applicable to, to reduce to process the vibration of workbench, ensures the machining accuracy of processing equipment job stability and raising gear.
The said chain digital control gear hobbing machine indexing worm of the utility model location structure is meant that the indexing worm rotating shaft is installed on the high rigidity endless screw support and keeps engaged transmission with dividing worm wheel.It constitutes, and the indexing worm axle is installed on the endless screw support, is provided with bearing between the end of described worm shaft and support, and the end of bearing is provided with fixture, and said fixture can be a locking nut.The bearing that is provided with between described worm shaft end and support can be rolling bearing, and the bearing that is provided with between described worm shaft end and support can be needle bearing.
The effect of the said chain digital control gear hobbing machine indexing worm of the utility model location structure is, owing between described indexing worm and support, adopted the wide-angle angular contact thrust ball bearing, and this bearing has radial location, and bearing capacity is big, the effect that positioning accuracy is high; Adopt the high accuracy needle bearing between indexing worm right-hand member and support, this bearing is done accurate radial location effect; And the bearing end adopts locking nut to fix.This makes that this mechanism can guarantee that machine tooling is large-scale, during heavy-duty gear, the indexing accuracy of workbench effectively stops the vibration of workbench under big cutting force effect, improves the Gear Processing accuracy class, and has optimized the workbench calibration drive mechanism of chain digital control gear hobbing machine.
Description of drawings
Accompanying drawing 1: large-sized numerical control gear hobbing machine worktable indexing worm location structure is implemented schematic diagram.
The specific embodiment
Accompanying drawing 1 is that large-sized numerical control gear hobbing machine worktable indexing worm location structure is implemented schematic diagram.Said indexing worm axle 1 is installed on the endless screw support 2, between end of described worm shaft 1 and support, be provided with rolling bearing 3, be provided with needle bearing 4 between the other end of described worm shaft 1 and support, the end of rolling bearing 3 and needle bearing 4 has been provided with the locking nut 5 of fixation.
The said large-sized numerical control gear-hobbing machine of the utility model indexing worm location structure, adopt high rigidity between its indexing worm left end and support, high accuracy wide-angle angular contact thrust ball bearing, this bearing is done accurate axial, radial location, bearing capacity is big, the positioning accuracy height, bearing inner race is fixed on the worm shaft with locking nut, and the outer ring is fixed on the support with ring flange; Adopt the high accuracy needle bearing between indexing worm right-hand member and support, this bearing is done accurate radial location effect, and the bearing right-hand member is fixed with locking nut.Enable to guarantee lathe when machining large, heavy-duty gear, improve the indexing accuracy of workbench, effectively stop the vibration of workbench under big cutting force effect, improve the Gear Processing accuracy class.
