Description
Technical field
The present invention relates to the teaching equipment field, particularly a kind of dual-purpose gear generating appearance.
Background technology
Generating method be utilize a pair of gear (or rack-and-pinion) when intermeshing its conjugate profiles each other the principle of envelope process the gear teeth; Add man-hour, wherein one take turns (or tooth bar) for cutter, another is a wheel blank; Both guarantee the angular velocity ratio transmission fixed; As a pair of real gear (or rack-and-pinion) engaged transmission, simultaneously cutter also along wheel blank axially make cutting movement, the flank profil of institute's cut gear resembles the envelope of blade in each position like this.If with involute urve as cutter tooth-profile; Then its envelope must also be an involute urve; Owing to can't see blade forms envelope in each position process man-hour in actual adding; So demonstrate through the generate appearance and between wheel blank and cutter rolling cut to be cut process, each position that cutter blade once occupied when " cutting " is recorded on drawing with pencil, just can be observed the process of gear generating.
At present, gear generating appearance as shown in Figure 1 drafting gear commonly used comprises frame 1 ', tooth bar slotting tool 2 ', screw rod 3 ', supporting plate 4 ', disk 5 ' and block 6 ' in teaching, and its used cutter is a tooth bar slotting tool 2 '; Disk 5 ' represent the wheel blank of being made gear and be installed on the frame 1 ' its can rotate around the O axle, represent the tooth bar slotting tool 2 ' of cutting tool to be installed on the planker 4 ' rotary screw 3 ' during adjusting; Can make the toothed region of tooth bar slotting tool 2 ' be placed in each diverse location of relative disk 5 '; The radial distance at expression tooth bar slotting tool 2 ' cutter center line to wheel blank center moves apart from Xm, can obtain through the reading on the left side; When aliging two zero points; The center line of expression reference circle and rack cutter is tangent, i.e. cutting master gear, if two zero points Xm apart; Represent that then the gear compound graduation circle separates the cutting X-gear with the tooth bar center line.
At present school uses gear generating appearance as shown in Figure 1 to draw gear mostly, be to position cutting on the circular paper on the circular external part that a roundlet is enclosed within it disk 5 ' more earlier, therefore since roundlet cut; Its radius is if cut too smallly, and then the student is difficult for circular paper is enclosed within on the circular external part, if the excessive circle that then can cause is eccentric; And owing to be to position the moving carriage 4 ' regular meeting that draws often through circular external part to drive paper and move; The accuracy of the drawing that influence is drawn, and because the gear generating appearance in use, is the end that first moving carriage 4 ' is pushed into tooth bar slotting tool 2 ' in the generate appearance; Move the distance about 3mm to the other end then; Draw, so constantly move down, finally these dense profiles of tooth promptly demonstrate the envelope of oneself; Be by the tooth curve of gear cutting machine, displacement is excessive because this device operator is difficult to hold for student so displacement mostly then is difficult to draw out tooth curve.
Inventor herein such as Fig. 2 improve original gear generate appearance structure for this reason, change the column external part of original disk 5 ' into a plurality of pin portion, when the student uses with the paper circle directly nail on disk, can position; Make that paper circle location is more accurate; More convenient to operate, position through a plurality of pin portion, thereby can not being moved when rotated, disk 5 ' improves the accuracy of drawing greatly; And this patent is provided with elasticity extension and corrugated part; The elasticity extension may be stuck in the different wave troughs of corrugated part during mobile pallet 4 ', can supporting plate 4 ' be moved 2～3mm through sensation, and the student uses very convenient; The tooth curve of the gear of being drawn is more accurate, and the applicant has applied for 201120110327.6 utility models to this scheme and obtained the authorization.
Can only carry out tooth bar slotting tool Machining of Gear simulation test but this gear generating appearance is the same with original gear generate appearance; Can not carry out cam shaper cutter Machining of Gear simulation test; The applicant hopes this gear generating appearance is further improved because cam shaper cutter Machining of Gear simulation test is the same basically with tooth bar slotting tool Machining of Gear simulation test principle; Can carry out tooth bar slotting tool Machining of Gear simulation test and can carry out cam shaper cutter Machining of Gear simulation test again, thereby can make the student that tooth bar slotting tool Machining of Gear and cam shaper cutter Machining of Gear are had more deep understanding.
Summary of the invention
To above problem, the present invention makes the student can carry out tooth bar slotting tool Machining of Gear simulation test and can carry out cam shaper cutter Machining of Gear simulation test again through existing gear generating appearance structure is improved; Thereby make the student more deep understanding arranged to tooth bar slotting tool Machining of Gear and cam shaper cutter Machining of Gear, for reaching this purpose, the present invention provides a kind of dual-purpose gear generating appearance; Said gear generating appearance comprises frame, tooth bar slotting tool, supporting plate, disk, block and shaft collar, and said frame bottom is provided with support member, and said disk passes through screw retention on frame; Between said screw and the frame shaft collar is installed, said disk comprises the tooth portion that connects, circle portion and block fixture, and the supporting plate slide slot is arranged on the said frame; Said supporting plate one side has and the corresponding sliding part of frame supporting plate slide slot grooved; Said supporting plate is installed in through sliding part in the slide slot of frame, and the supporting plate upside has the gear teeth, and the said supporting plate gear teeth are connected tooth portion and are meshed with disk; Said disk circle portion is on the supporting plate gear teeth; There is the block fixture in central authorities of said disk circle portion, and said block is fixed in the disk circle portion through the block fixture, and said tooth bar slotting tool upside has toothed region; There are 2 bar shaped mounting grooves at tooth bar slotting tool middle part, and said adjusting screw(rod) is installed on the mounting groove and through mounting groove the tooth bar slotting tool is fitted on the supporting plate:
