Abstract
The utility model provides a cutter relieving device for a combing-cutter gear shaping machine, which is characterized in that a ram which can move up and down is arranged on an upright post of a gear shaping machine, a groove is arranged on the ram, and a cutter clamping body for placing a knife, which can lightly swing forwards and backwards is arranged in the groove; a geared sector which is engaged with a gear which is driven by frictional force is arranged on the upper end of the cutter clamping body, the other end of a gear shaft is provided with a driving gear, and the driving gear is engaged with a gear rack which is fixed on the upright post and is parallel to the moving direction of the ram. The device removes a cutter frame body which is arranged on the upright post and a cam drive mechanism which drives the cutter relieving device to move, and thus, the structure is greatly simplified, and the manufacturing cost is reduced. Additionally, the utility model also has the advantages of simple and convenient repair.
Description
Technical field
The utility model relates to the gear shapping machine of Gear Processing, especially a kind of chasing tool gear shapping machine tool retracting device.
Background technology
Present known gear shapping machine tool retracting device, mainly be that tool-post structure is installed on column, the ram of pinion cutter is installed on the tool-post structure, drive tool-post structure by cam mechanism and do the cutter relieving motion, its cam mechanism mainly contains: cam-and-, cam wedge mechanism, two roller cam mechanism, the major part of these mechanisms is cams.Curve design in the gear shapping machine cam needs several curve intersections to need smooth connection at the intersection point place, otherwise will be had a strong impact in the flank of tooth fineness that adds work gear, and this cam manufacturing cycle is long, processing charges height (can only process on numerically control grinder and contour grinder).Complex structure not only on the kind of drive, maintenance is inconvenience also, and especially cam most users that are damaged are then powerless.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, cost is low, the chasing tool gear shapping machine tool retracting device of easy-maintaining.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of chasing tool gear shapping machine tool retracting device, column by gear shapping machine, the ram that moves up and down that is installed on the column is formed, ram is shaped on groove, the folder cutter hub that has axle is installed in the groove, the upper end of folder cutter hub is shaped on the tooth fan, its lower end is shaped on boss, the locating piece and the rubber blanket that limit folder cutter hub oscillating quantity are installed on the ram of boss both sides, the gear that is meshed with the tooth fan that has axle also is installed in the groove, one side of gear is provided with ring shaped slot, by screw mounting spring and frictional disk in ring shaped slot, two frictional disks that are slidingly connected with axle and key also are installed and are regulated the nut of frictional force in the gear both ends of the surface, on the gear shaft in the groove outside, driving gear is installed, on column, is installed tooth bar with the driving gear engagement.
Advantage and the good effect that the utlity model has are: because by the cog structure of transferring power of column upper rack and ram, the gear and the engaging tooth fan that have the frictional force transmission are installed in the ram groove are done little swing, finish the cutter relieving motion, saved the cam drive of tool-post structure and driving tool-post structure, simplify the structure, not only shorten the manufacturing cycle, and reduce manufacturing cost greatly, in addition, the utility model also has the advantage of easy maintenance.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, the ram 33 that is slidingly installed on the gear shapping machine column 7 and moves up and down.Be shaped on groove on the ram, the folder cutter hub of swinging 1 that has axle 24 is installed in the groove, an end of axle 24 is fixing with dog screw 32, and the other end is equipped with and stops up 23, for lubricated, also is lined with copper sheathing 25 and dog screw 22 on the axle 24.The lower end of folder cutter hub installs and fixes the screw 2 and the positioning key 3 of cutter.The lower end of folder cutter hub 1 also is shaped on boss 35, and the locating piece 4 and trip bolt 5 and adjusting pad 6, rubber blanket 8 and trip bolt 9 thereof and the adjusting pad 10 that limit folder cutter hub 1 oscillating quantity are installed on the ram groove of boss both sides.Folder cutter hub upper end also is shaped on tooth fan 34.The gear 11 of tape spool 18 also is installed in the ram groove of folder cutter hub top, and gear can relatively rotate with axle 18.One side of gear 11 has ring shaped slot, and spring 12 and frictional disk 26 thereof and mounting screw 31 are installed in the ring shaped slot.In the both ends of the surface of gear 11 frictional disk 14,27 that is slidingly connected with axle 18 and key 13 and lock washer and the nut 28 of regulating frictional force are installed also.One end of axle 18 is equipped with the pad and the circlip 30 of locking, and the other end stretches out the ram side and the pad 16 and the circlip 17 of locking also are installed.The external part of axle 18 also is equipped with driving gear 20 and fastening nut and lock washer 19 thereof.On gear shapping machine column 7, also install the tooth bar 21 that with driving gear 20 be meshed parallel with ram 33 directions of motion.For lubricated, copper sheathing 15 and 29 also are installed at the two ends of axle 18.
Operating principle:
When ram 33 was descending, the frictional disk 14,27 that tooth bar 21 rubbing driving gears 20 drive on the axle 18 made gear 11 drive folder cutter hub 1 swing of teeth fan 34, stretches out cutter.
When ram 33 was up, tooth bar 21 rubbing driving gears 20 (reverse rotation) drove the frictional disk 14,27 on the axle 18, made gear 11 drive folder cutter hub 1 swing (oppositely) of teeth fan 34, return cutter.
