Description
Technical field
The present invention relates to the Machining Technology field, be specifically related to a kind of milling machine main speed changing poaptor.
Background technology
In the process that the employing milling machine is processed, need operate the transformation of speed of milling machine usually, so that milling machine obtains different rotating speed.For existing gear controller; It is the axle axial displacement that makes three shifting slide gears through multilevel gear drive mechanism; Drive three shifting slide gears and move axially, thereby pass through meshing of three shifting slide gears, obtain different output speeds in different working position and output gear.Because the structure of multilevel gear drive mechanism is not only complicated, require great effort very much during operation, and cost is high.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, light milling machine main speed changing poaptor of operation, simultaneously, the present invention has the low advantage of cost.
The milling machine main speed changing poaptor; Choosing speed dish is arranged on the housing; Choosing speed dish is connected with first bevel gear through axle, first bevel gear and the engagement of second bevel gear, and second bevel gear is connected with a porose disc through power transmission shaft; This porose disc is provided with several first through holes and second through hole; The end that the first speed change ratch and the second speed change ratch are provided with multidiameter is inserted into respectively in first through hole or second through hole, the first speed change ratch and the second speed change ratch and a travelling gear engagement, and the first speed change ratch is connected with three shifting slide gears through shift fork; On said power transmission shaft, be provided with the porose disc shift fork, an end of this porose disc shift fork is connected with a ratch, this ratch and a sector gear engagement, and sector gear is connected with control crank through bearing pin.
Adopted such scheme, when needing speed change, switching left after handle depressed through the rotation of sector gear, drives ratch and moves right with the porose disc shift fork, and porose disc is moved right with it, breaks away from the first speed change ratch and the second speed change ratch.Rotate choosing speed dish then, confirm that needed rotating speed is corresponding with arrow labeled 18 grades of rotating speeds on selecting the speed dish,, the bevel gear that is fixed on its end is rotated, drive bevel gear and rotate, thereby make porose disc also turn to a certain position thereupon through rotating choosing speed dish.Again handle is removed to original position,, porose disc is moved to the left slippages through sector gear, ratch and shift fork.Since on the porose disc position of respective aperture with vary in size; Effect through the ladder pin on the first speed change ratch and the second speed change ratch; Just can make the first speed change ratch and the second speed change ratch correspondingly do certain moving axially; Promote shift fork, three shifting slide gears are shifted one's position, to reach the purpose of conversion rotating speed.
Structure of the present invention is comparatively simple, when needing conversion rate, only needs that control crank is applied less turning power and can carry out variable speed operation.
Description of drawings
Fig. 1 is a structural representation of the present invention;
In the accompanying drawing, 1 is shift fork, and 2 is the first speed change ratch, and 2a is three shifting slide gears, and 3 is travelling gear, and 4 is the second speed change ratch; 5 is porose disc, and 5a is first through hole, and 5b is second through hole, and 6 is the porose disc shift fork, and 7 are the impulsion switch; 8 is control crank, and 9 is push rod, and 10 is projection, and 11 are choosing speed dish, and 11a is an axle; 12 is first bevel gear, and 13 is the engagement of second bevel gear, and 13a is a power transmission shaft, and 14 is ratch, and 15 is sector gear.
The specific embodiment
With reference to Fig. 1; Milling machine main speed changing poaptor of the present invention, choosing speed dish 11 is arranged on the housing, and choosing speed dish is connected with first bevel gear 12 through axle 11a; First bevel gear 12 and second bevel gear engagement 13; Second bevel gear 13 is connected with a porose disc 5 through power transmission shaft 13a, and this porose disc 5 is provided with several the first through hole 5a and the second through hole 5b, and the end that the first speed change ratch 2 and the second speed change ratch 4 are provided with multidiameter is inserted into respectively among the first through hole 5a or the second through hole 5b; The first speed change ratch 2 and the second speed change ratch 4 and travelling gear 3 engagements, the first speed change ratch 2 is connected with three shifting slide gear 2a through shift fork 1.On power transmission shaft 13a, be provided with porose disc shift fork 6, an end of this porose disc shift fork 6 is connected with a ratch 14, this ratch 14 and sector gear 15 engagements, and sector gear 15 is connected with control crank 8 through bearing pin.When speed change is handled,, prevent that tooth from pushing up with tooth mutually, on sector gear 15, be provided with projection 10 in order to protect the smooth joint between gear, an end in contact of this projection 10 and a push rod 9, the other end of this push rod 9 contacts with impulsion switch 7.When moving handle 8 and rotate, projection 9 compressing push rods 9, moment is connected impulsion switch 7, makes initiatively motor instantaneous starting, drives each instantaneous revolution in the main spindle box, and at this moment shifting slide gear is meshed with fixed gear, just the phenomenon that tooth and tooth push up mutually can not occur.The impulsion switch can also work the protective effect that prevents mistake speed change during main axis rotation except that playing above-mentioned effect.If in the process of main axis rotation, pull handle 8, the projection momentary connections impulsion switch 7 below the sector gear 15, then main motor is braked immediately and is stopped the rotation, and can avoid damaging gear like this.
During speed change, switching left after handle 8 depressed through the rotation of sector gear 15, drives ratch 14 and moves right with porose disc shift fork 6, and porose disc 5 is moved right with its axle, breaks away from the first speed change ratch 2 and the second speed change ratch 4.Rotate choosing speed dish 11 then; Confirm that needed rotating speed is corresponding with arrow labeled 18 grades of rotating speeds on selecting the speed dish, rotate through rotating choosing speed dish, can make the bevel gear 12 that is fixed on its end; Drive bevel gear 13 and rotate, thereby make porose disc also turn to a certain position thereupon.Again handle 8 is removed to original position,, porose disc 5 is moved to the left slippages through sector gear 15, ratch 14 and shift fork 6.Since on the porose disc position of respective aperture with vary in size; Effect through the ladder pin on the first speed change ratch 2 and the second speed change ratch 4; Just can make the first speed change ratch 2 and the second speed change ratch 4 correspondingly do certain moving axially; Promote shift fork, three shifting slide gears are shifted one's position, to reach the purpose of conversion rotating speed.
