Abstract
The utility model relates to a gear hobbing teeth indexer used for horizontal milling machines and universal milling machines, solving the problems that gear form is not accurate and the cutters are excessive when cutting gear with ordinary indexer. The main body is box-body structured and is provided with teeth indexer change-speed gear. One end of the teeth indexer transmission chain is connected with a cutter bar and a rotary tool of the milling machine, the other end is connected with a worm, a worm gear, a main shaft of teeth indexer, a gear blank shaft and a gear blank successively via an oscillating axle and a clutch. The teeth indexer movement is realized via selecting the teeth indexer change-speed gear. When processing, the worktable of the milling machine does not make vertical movement and the axial feed is realized via a screw thread pair of a tailstock. Since the gear plank shaft is rotating when processing, the screw sleeve can be driven to rotate via a clamping device. Since the screw does not rotate now, then when rotating, the screw sleeve can drive the gear blank shaft and the gear blank to move axially to realize axial feed. Radial feed is realized via lifting the worktable of the milling machine. The teeth indexer can be used to make gears, wormgears and other parts with generating method.
Description
Affiliated technical field
The utility model is a kind of machine tool accessories-minute tooth head that is used to add work gear.It can add work gear on horizontal milling machine and universal milling machine.
Background technology
The machine tool accessories that can add work gear at present on above-mentioned milling machine has dividing head.Though dividing head can be used for adding work gear, it is processed with form cutting.The form of gear tooth that processes is inaccurate, and the gear of same modulus often need be selected different cutter number for use because of number of teeth difference.
Summary of the invention
In order to overcome the deficiency of known machine tool accessories, the utility model provides a kind of novel machine tool accessories-minute tooth head.It can add work gear on above-mentioned milling machine, the form of gear tooth that processes is accurate, and the gear of processing the various numbers of teeth of same modulus is only used a kind of cutter.
The technical scheme that the utility model adopted adds work gear with generating.The main motion of Tool in Cutting is from milling machine spindle.Add and man-hour divided teeth gear need be installed.One end of dividing tooth transmission chain links to each other with milling machine knife bar, hobboing cutter, and the other end is then by swinging axle, shaft coupling, worm screw, worm gear, branch tooth head main shaft, tooth base axle, dividing the tooth motion to pass to the tooth base.Divide tooth head main shaft with being to connect between the tooth base axle, so both can transmit motion, can make again in the keyway of key in minute tooth head main shaft of tooth base axle one end and slide with the key that is slidingly matched.By calculating and selecting divided teeth gear, realize the required number of teeth.Add the man-hour milling machine table and do not vertically move, the axial feed of tooth base is to finish by the cooperation of thread bush in the tailstock and screw rod.Because thread bush (or screw rod) links to each other with the tooth base axle that is rotating by clamping device, and with the screw rod (or thread bush) of its corresponding matching be fixed, therefore thread bush (or screw rod) will drive tooth base axle when rotating, the tooth base axially moves, and this has just formed axial feed.The radial feed of tooth base is finished by promoting milling machine table.
The tooth header structure was simple in this minute, and formed an integral body, unloaded conveniently under installing.It can be used for processing straight spur gear and worm gear etc., also can be used to process helical gear.If the processing helical gear only need be made screw type getting final product to the key portion of tooth base axle according to the lead of helix of gear.This is suitable for producing repeatedly of approved product.
This minute tooth head do not have Bevel Gear Transmission again, so easy to manufacture because driving-chain is short.And these factors also are favourable to improving the rigidity of transmission system to improving machining accuracy.
In addition, less demanding to milling machine of this minute tooth head.As long as milling machine spindle can normally rotate,, just can process qualified gear as long as milling machine table can normally handly on three directions move and can lock.
Description of drawings
Fig. 1 is the branch tooth drive path figure of this minute tooth head, and Fig. 2 has shown its machining and axial feed.1 is hobboing cutter in the drawings, the 2nd, and the milling machine knife bar, the 3rd, milling machine spindle, E, F, a, b, c, d are the gears in the dividing tooth transmission chain, wherein a, b, c, d are change gears.The 4th, swinging axle, the 5th, shaft coupling, the 6th, worm screw, the 7th, worm gear, the 8th, minute tooth head main shaft, the 9th, tooth base axle, the 10th, tooth base, the 11st, clamping device, the 12nd, thread bush, the 13rd, screw rod, the 14th, handwheel, the 15th, dog screw.
The specific embodiment (referring to accompanying drawing)
In the drawings, milling machine spindle 3 drives knife bar 2 rotations, and knife bar 2 drives hobboing cutter 1 rotation, and this has just formed the main motion to 10 cuttings of tooth base.Divide the tooth drive path as follows: hobboing cutter 1-knife bar 2-gear E-gear F-gear a-gear b-gear c-gear d-swinging axle 4-shaft coupling 5-worm screw 6-worm gear 7-divide tooth head main shaft 8-tooth base axle 9-tooth base 10.Motion transmission from minute tooth head main shaft 8 to tooth base axle 9 cooperates by key finishes (seeing accompanying drawing 1 and accompanying drawing 2), and an end of tooth base axle 9 has key, and dividing in the tooth head main shaft 8 has keyway.Select change gear a, b, c, d, hobboing cutter 1 is goed around, tooth base 10 turns over K tooth (K is a number of hobboing cutter).Axial feed is to realize (being fixed as example with screw rod) like this: the rotation of tooth base 10 and tooth base axle 9 drives thread bush 12 rotations by clamping device 11.Because this moment can not rotate, so thread bush 12 will drive tooth base axle 9 in rotation and tooth base 10 axially moves in screw rod 13 and handwheel 14 screw 15 location that have been positioned, this has just formed the axial feed motion of tooth base 10.Slide in the keyway of key tail in minute tooth head main shaft 8 of tooth base axle 9 at this moment.
The radial feed that adds man-hour is realized by promoting milling machine table.In order to obtain final machining accuracy, should be taken into account during change gear: when radial feed put in place, the center height of gear E and gear F should equate, and this moment, two gear meshing degrees of tightness were suitable.
