Abstract
The utility model discloses a headstock, in particular to a headstock using an electric push rod to drive the automatic gear shift, comprising a body (1) and a variable-speed driving shaft (8) arranged on the body (1). The headstock is characterized in that the outer end head of the variable-speed driving shaft (8) is fixedly connected with one end of a swing link (9), and the other end of the swing link (9) is rotatably connected with the outer end head of a push rod (7) in the electric push rod; and an installing end (19) on a shell (11) of the electric push rod is rotatably connected with the body (1). During gear shifting, an electric control device drives the electric push rod to lead the variable-speed driving shaft to rotate, thereby driving a shifting fork to shift a variable-speed traveling gear to travel and achieving the purpose of speed changing conveniently without shutting down the machine; in addition, the utility model has the advantages that the efficiency is high, the labor intensity of the operator is reduced, the overall structure is simple, the manufacturing cost is lowered, and the operation is flexible and reliable and accurate.
Description
Technical field
The utility model relates to a kind of headstock, and particularly a kind of electric pushrod that utilizes drives self shifter formula headstock.
Background technology
The headstock gearshift of low-cost type CNC lathe, the tradition method of operating mostly adopts manual three retaining modes of operation, promptly drive the gear that cam rotates to setting by the external control crank of manual rotation, drive two groups of link rods, control lever shaft and shift forks simultaneously by cam, two groups of combination gears that drive on the splined shaft carry out axial displacement, thereby shift transformation is carried out in the engagement and the disengaging that realize coupling gear, drives main shaft and does high, medium and low speed rotation.This manual shift mode has following several respects shortcoming, and the first need be shut down gearshift, inefficiency; The 2nd, the machine driving link is many, the fault rate height, and frictional resistance is big, the manually-operated effort; The 3rd, cam rail groove processed complex, precision is difficult for guaranteeing; The 4th, handle set machinery detent mechanism complexity, easy glide is crossed the position, causes gears engaged width deficiency.
Summary of the invention
The purpose of this utility model need not when providing a kind of gearshift shutdown, efficient height, simple in structure, easy to operate, precision is high, gearshift utilizes electric pushrod to drive self shifter formula headstock flexibly accurately, overcomes the deficiencies in the prior art.
The electric pushrod that utilizes of the present utility model drives self shifter formula headstock, comprise casing 1 and the variable speed drives axle 8 that is installed on the casing 1, it is characterized in that: the external end head of described variable speed drives axle 8 is fixedlyed connected with an end of fork 9, the other end of fork 9 and the external end head of the push rod in the electric pushrod 7 are rotationally connected, and are rotationally connected between installation end 19 on the housing 11 of electric pushrod and the casing 1.
The electric pushrod that utilizes of the present utility model drives self shifter formula headstock, and the outside of wherein said variable speed drives axle 8 is connected to fork axle 17, has pin 18 to fixedly connected between fork axle 17 and the fork 9.
The electric pushrod that utilizes of the present utility model drives self shifter formula headstock, and bolting has mounting disc 2 on the wherein said casing 1, is rotationally connected by bearing pin 3 between the installation end 19 on the housing 11 of mounting disc 2 and electric pushrod.
The electric pushrod that utilizes of the present utility model drives self shifter formula headstock; can drive electric pushrod by electric control gear when gearshift rotates the variable speed drives axle; thereby the drive shift fork is stirred the speed change carrier wheel and moved the purpose that reaches speed change, and is very convenient, need not to shut down; the efficient height; reduced operator's labour intensity, overall structure is simple, has reduced manufacturing cost; flexible movements are reliable, and are accurate.
Description of drawings
Fig. 1 is the casing external structure schematic diagram of the utility model specific embodiment;
Fig. 2 is a headstock internal structure schematic diagram.
The specific embodiment
As shown in Figure 1, 2: 1 is casing, the driving lever 12 that the change gear shaft 10, speed change carrier wheel 16, declutch shift shaft 14, shift fork 13 of spline form is housed in the inside of casing 1, matches with shift fork 13, the parts such as variable speed drives axle 8 that join with driving lever 12, above-mentioned is the prior art part, no longer auspicious stating.
The electric pushrod of being made up of parts such as motor 4, housing 11, cylinder body 6, push rods 7 is the optional component and the outside that is installed in casing 1, concrete mounting structure is: by bolting mounting disc 2 is arranged on casing 1, the installation end 19 that joins with housing 11 in the electric pushrod is inserted in the open slot in the mounting disc 2 and by bearing pin 3 mounting disc 2 and installation end 19 is rotatably connected, and makes between electric pushrod and the casing 1 and realizes being rotationally connected.
The external end head of the push rod 7 in the electric pushrod is rotationally connected by the end of connecting axle 10 with fork 9.
The other end of fork 9 is fixedlyed connected with the external end head of variable speed drives axle 8, concrete connected mode is: an end of fork axle 17 has the termination of the shape of tetragonal body, this termination is inserted in the groove at variable speed drives axle 8 external end head places, and the termination point casing of fork 9 is contained on the fork axle 17 and locatees fastening with pin 18.
Each variable speed drives axle in the casing 1 all is furnished with a cover electric pushrod mechanism.
During work, motor lead in the electric pushrod 5 and electric control gear are joined, when shifting gears as needs, can drive the electric pushrod action by electric control gear and can drive 8 rotations of variable speed drives axle, thereby drive driving lever 12, shift fork 13 actions, stir speed change carrier wheel 16 by shift fork 13 and move, can reach the purpose of speed change, very convenient.
