Abstract

The utility model discloses an internal spline and key flank grinding machine in the vertical type, characterized in that a miniature grinding head is arranged on the machine body, the worktable is provided with a chucking positioning device which is composed of tension spindle; the internal spline and key flank grinding machine can be aligned once, having convenient chucking. The feed mechanism adopts a micro feeding device in the wedge type, and an oil cylinder pushes the wedge to drive a slide plate and work piece for micro feeding; the internal spline and key flank grinding machine has accurate feeding, having high machining accuracy, and having reliable performance.

Description

Internal spline and key flank grinding machine

The utility model relates to a kind of grinding machine, particularly endoporus spline key side grinding bed.

In the prior art, domestic still do not have this series products, the similar products of West Germany Puli company, Lin Baige company of Switzerland section all are horizontal structures in the world, workpiece is tightened by universal chuck, look for the table location, the general general grinding machine of delivering gear, inconvenience therefore is installed, the chip removal performance is bad, and inconvenient operation, efficient be low, cost an arm and a leg.

The purpose of this utility model provides a kind of endoporus spline key side grinding bed that can overcome shortcoming in the prior art, and it is easy and simple to handle, the amount of feeding is accurate, can obviously improve machining accuracy.

Task of the present utility model is finished like this:

Lathe bed adopts vertical structure, and miniature bistrique, workbench are contained on the lathe bed, and slide plate is contained on the workbench, has the dividing head that tightens positioner and is installed on the slide plate, and the chucking detent mechanism is made up of tensioner mandrel and fastening bolt.The two side of tensioner mandrel has boss, the boss axis direction has long rabbet, mandrel spreading chucking workpiece during the turn fastening bolt, and rely on boss and spline to locate, be installed so convenient needn't the his-and-hers watches centering, saved the time of being installed, slide plate is promoted by the Wedge type micro-feed mechanism, feeding work when finishing grinding, micro-feed mechanism is made up of eccentric shaft, wedge, oil cylinder.Because the gradient of wedge is very little,, guaranteed that feeding is accurate so the journey error of oil cylinder is just very little to the influence of feeding size.The utility model has overcome the shortcoming of prior art, and cost low, help promoting.Use the utility model to add the splined hole of work gear, can reduce the transmission noise, improve transmission accuracy, obviously improve crudy.

Below in conjunction with accompanying drawing the utility model is described in detail:

Fig. 1 is the front view of a kind of specific embodiment of the present utility model.

Fig. 2 is the left view of Fig. 1.

Fig. 3 is the partial sectional view of micro-feed mechanism.

Fig. 4 is the A-A cutaway view of Fig. 3.

Fig. 5 is the partial sectional view of chucking positioner.

Fig. 6 is the vertical view of Fig. 5.

Fig. 7 is that the A of Fig. 5 is to view.

Among Fig. 1,2, miniature bistrique 1 is housed on the vertical lathe bed 3, and the workbench 4 that has micro-feed mechanism 2 and chucking positioner 6, control system is made up of Hydraulic Station 5, electronic box etc.Miniature bistrique 1 can use prior art.Micro-feed mechanism 2 is as Fig. 3, shown in 4, the upglide surface of workbench 4 is equipped with the slide plate 11 that fixing dividing head is used, one end of slide plate 11 is equipped with support 15, eccentric shaft 14 and the latch segment 13 and the backup plate 12 that compress eccentric shaft 14 are contained on the support 15, the eccentric part of eccentric shaft 14 is slidingly matched with the wedge 16 that is fixed in the upper slide 17, upper slide 17 links by dovetail groove with the lower skateboard 18 that is fixed on the workbench 4, the piston rod of oil cylinder 19 is fixed on the upper slide 17, promotion upper slide 17 made slide plate 11 do the feed motion of trace by the inclined-plane promotion eccentric shaft 14 of wedge 16 when piston moved, the gradient of wedge preferentially selects 30080.05 for use, oil cylinder piston moves the 60mm stroke like this, be fixed in the only mobile 0.01mm of workpiece on the slide plate 11, the microfeed work when finishing grinding.Unclamp latch segment 13, tuningout axle 14 can be suitable for the wide workpiece of different keys.The other end of slide plate 11 is equipped with back pressure oil cylinder 9, relies on support 7 to be fixed on the workbench 4, and the piston rod 10 in the oil cylinder 9 is pushing away slide plate 11, has eliminated the gap between the micro-feed mechanism workpiece, prevents creeping phenomenon, has guaranteed the reliability of work.

On slide plate 11, be equipped with by the chucking positioner shown in Fig. 5,6,7 by dividing head or widely different commentaries on classics workbench, the endoporus of tensioner mandrel 20 has tapering, and match with the tapering of fastening bolt 21, the two side of tensioner mandrel 20 has long rabbet, and its position is consistent with the center line of two boss.Two boss are used for to the keyway location of workpiece, screw fastening bolt 21 and can tighten workpiece and accurate location.So needn't look for table to align after workpiece is installed and finishes again, improve efficient.

The utility model is mainly used to the grinding worm splined hole, in the time of can solving gear drive because the shortcoming that transmission accuracy is low, noise is big that causes is forbidden in spline centering.
