Description
Technical field
The utility model relates to the feed change mechanism of horizontal lathe, relates in particular to the selector gear of sealing feed box stepped gear.
Background technology
The feed box system of horizontal lathe generally by basic group of mechanism, increase times mechanism and move converting mechanism and form.The version of basic group mechanism has several forms, and wherein Nuo Dun mechanism is traditional a kind of common mechanism, and is widely used, but because to adopt the casing of this mechanism be Open architecture, can't seal, trapped fuel, the lubricating condition of movement parts is relatively poor when causing turning round; And the strength member location-plate of operating mechanism, be the front that is placed on casing, according to the pause quantity of stepped gear of promise, must on this location-plate, process many elongated slots, this both made troubles to processing, also had influence on the outward appearance of whole lathe.Afterwards at the problems referred to above, people improve on former basis this Open architecture, though through the Nuo Dun mechanism after improving, salable, the trapped fuel of casing, the lubricating condition of movement parts is improved during running, and add man-hour at location-plate, and need not process many elongated slots, changed outward appearance; But the complexity that this mechanism operating frame mode becomes, cumbersome; Not only workpiece is many, and the size of workpiece and position accuracy demand height, has brought difficulty for processing, assembling, dismounting maintenance.
The utility model content
Problem to be solved in the utility model provides a kind of ectonexine operating mechanism, makes it can carry out simple and convenient ground to the stepped gear of sealing feed box and handles, and realizes the speed change of feed box.
The selector gear of the utility model horizontal lathe sealing feed box stepped gear, it comprises the ectonexine operating mechanism; A, outer operating mechanism comprise outdoor handle seat, outdoor handle, rotating shaft, cam, go up location-plate, following location-plate: the two ends of rotating shaft are separately fixed in the endoporus of outdoor handle seat, cam by pin; Last location-plate is fixed on the gusset in the casing, and an end of following location-plate is fixed on the gusset in the casing, and the other end is a free end, and it is supported on the top of cam, forms circular hole up and down between the location-plate, and the pause number of stepped gear of the number of circular hole and promise is identical; B, internal layer operating mechanism comprise inner handle seat, inner handle, tooth axle sleeve, driving lever, tooth bar, alignment pin: the inner handle seat is connected with the tooth axle sleeve by flat key, the tooth axle sleeve is meshed with tooth bar on being contained in driving lever, alignment pin is fixed on promise and pauses on the frame, is installed in the circular hole; C, outdoor handle seat abut against on the end face of inner handle seat.
The rotation of the utility model selector gear by cam holds out against and unclamps location-plate down, and by alignment pin with the upper and lower together swing of location-plate down, realize that promise pauses frame gear and stepped gear in the engagement or the disengagement of each position, realized the speed change of stepped gear.This novel exchange of passing through one group of integrated handle centralized control stepped gear has realized the speed change of stepped gear easily.The utility model is simple in structure, and not only process, install simply, use, easy to maintenance, and also outward appearance is succinct, attractive in appearance, has stronger practicality.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is elaborated:
Fig. 1 is the front view of the utility model selector gear;
Fig. 2 is that the K of Fig. 1 is to view.
The specific embodiment
From Fig. 1 and Fig. 2 as can be known, the selector gear of the utility model horizontal lathe sealing feed box stepped gear, it is characterized in that: it comprises the ectonexine operating mechanism; A, outer operating mechanism comprise outdoor handle seat 1, outdoor handle 20, rotating shaft 18, cam 4, go up location-plate 9, following location-plate 8: the two ends of rotating shaft 18 are separately fixed in the endoporus of outdoor handle seat 1, cam 4 by pin; Last location-plate 9 is fixed on the interior gusset of casing, one end of following location-plate 8 is fixed on the interior gusset of casing, and the other end is a free end, and it is supported on the top of cam 4, form circular hole 22 up and down between the location- plate 9,8, the pause number of stepped gear 13 of the number of circular hole 22 and promise is identical; B, internal layer operating mechanism comprise inner handle seat 2, inner handle 19, tooth axle sleeve 3, driving lever 7, tooth bar 5, alignment pin 17: inner handle seat 2 is connected with tooth axle sleeve 3 by flat key 21, tooth axle sleeve 3 is meshed with tooth bar 5 on being contained in driving lever 7, alignment pin 17 is fixed on promise and pauses on the frame 6, is installed in the circular hole 22; C, outdoor handle seat 1 abut against on the end face of inner handle seat 2.
When needs carry out the stepped gear feed change, at first rotate counterclockwise outdoor handle 20 and outdoor handle seat 1, rotate counterclockwise together by pin drive rotating shaft 18, cam 4, make down location-plate 8 around the counterclockwise bottom of stiff end, thereby alignment pin 17 and promise frame 6, the promise frame gear 15 that pauses that pauses is moved down clockwise around swinging axle 14, the promise frame gear 15 that pauses is separated with the stepped gear 13 that is fixed on the I axle 12; Rotate inner handle 19 and inner handle seat 2 then, driving tooth axle sleeve 3 by flat key 21 rotates, because tooth axle sleeve 3 is meshed with tooth bar 5 on being contained in driving lever 7, driving lever 7 is stuck in promise again and pauses on the frame 6, frame gear 15 the moving axially thereby drive shifting slide gear 11 and promise are paused along II axle 10 and III axle 16, be clipped between location-plate 9 and the following location-plate 8 owing to alignment pin 17 simultaneously, can only tilt to move along the direction of circular hole 22, therefore promise is paused, and frame 6 one sides are mobile simultaneously swings, and keep promise to pause between frame gear 15 and corresponding stepped gear 13 tooth tops apart from constant, till moving to the stepped gear 13 that needs engagement (when inner handle seat 2 rotates, the spring of its inside, pellet shot from a slingshot, jackscrew plays the pause effect of each the gear meshing position in frame 15 and the stepped gear 13 of location promise); After moving into place, clockwise direction rotates outdoor handle 20 and outdoor handle seat 1, clockwise rotate together by pin drive rotating shaft 18, cam 4, make down location-plate 8 go up pendulum clockwise around stiff end, thereby alignment pin 17 and promise frame 6, the promise frame gear 15 that pauses that pauses is moved on counterclockwise around swinging axle 14, make promise pause frame gear 15 and stepped gear 13 engagements, alignment pin 17 is located in circular hole 22, thereby finishes the feed change process of stepped gear 13.
