The technical proposal is adopted as follows: A toothed rack (53), two fixing shafts (50) and a gear (52) is positioned in a box body (49). The toothed rack (53) is equipped with a chute of Z-direction (68) and a chute of X, Y-direction (69). The fixing shaft (50) is equipped with a U-shaped fork-lever (67, 60 and 55) and the U-shaped fork-lever is equipped with a sphere-shaped slide (54). The chute of Z-direction (68) coordinates with the sphere-shaped slide (54) on the U-shaped fork-lever. The sphere slide (54) coordinates with the chute of X, Y-direction (69) on the sphere-shaped slide (54). The selection and operation device of the feeding direction of the milling machine is mainly used on the selection operation of the transverse, longitudinal and vertical direction feeding of milling machine.

Description

The milling machine direction of feed is selected operating means

Technical field

The utility model relates to a kind of milling machine direction of feed and selects operating means.

Background technology

It is single that existing milling machine direction of feed is selected handle, a promptly vertical handle, and a horizontal handle, handle of lifting, complex structure, complex operation, manufacturing cost is bigger.

Summary of the invention

The technical problems to be solved in the utility model is: provide a kind of milling machine direction of feed to select operating means, it is simple in structure, and is easy and simple to handle, reduces manufacturing cost.

For solving the problems of the technologies described above, technical solution adopted in the utility model is to be provided with rack-plate, two fixed axis and gear in casing, described rack-plate be provided with Z to chute and X, Y to chute, described fixed axis is provided with the U-shaped shift fork and is provided with spherical sliding shelves thereon, Z cooperates with the sliding shelves of the sphere on the U-shaped shift fork to chute, and the sliding shelves of the sphere on the U-shaped shift fork cooperate to chute with X, Y.

Because the utility model only need be handled the feeding that a handle just can be controlled X, Y, three directions of Z, has realized the centralization operation, has simplified operating procedure, structure has become simply, has also reduced manufacturing cost simultaneously.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail:

As shown in Figure 1: in casing 49, be provided with rack-plate 53, two fixed axis 50 and gears 52, described rack-plate 53 be provided with Z to chute 68 and X, Y to chute 69, described fixed axis 50 is provided with U-shaped shift fork 67,60,55 and is provided with spherical sliding shelves 54 thereon, the sliding shelves 54 of the sphere of Z on chute 68 and U-shaped shift fork 67 cooperate, and sliding shelves of the sphere on the U-shaped shift fork 60,55 54 cooperate to chute 69 with X, Y.

Fig. 2 shows the operating structure of Y to feeding, handle 51 connects gears 52, gear 52 engaging tooth battens 53, and U-shaped shift fork 55 is through on the axle 50, and spherical sliding shelves 54 cooperate to chute 69 with the X shown in Fig. 3, Y, U-shaped shift fork 55 connects clutch 56, and clutch 56 and duplex clutch gear 58 cooperate.

Consult Fig. 3, Fig. 6, X, Y are upturned to the two ends of chute 69, when rack-plate 53 slippage to the right, when spherical sliding shelves 54 are in the position that right-hand member is upturned, because the angle of the axes intersect of the vertical line of U type shift fork 55 and spherical sliding shelves 54 is greater than 90 degree, U-shaped shift fork 55 is just stirred clutch 56 engagements, drives duplex clutch gear 58 and rotates, and finishes the operation that Y selects to feeding.When rack-plate 53 slippage left, the sliding shelves 54 of sphere on the U-shaped shift fork 60 are in X, Y when position that the chute left end is upturned, and U-shaped shift fork 60 is just stirred clutch 62 engagements, drive clutch gear 63 and rotate and finishes the operation that X selects to feeding.Sliding shelves of sphere on another U-shaped shift fork 67 54 cooperate to chute 68 with Z, and when mediating as shown in Figure 1 position, under the effect of spring 70 shown in Figure 6, U-shaped shift fork 67 is stirred clutch 65 engagements, drive clutch gear 64 and rotate, finish the operation that Z selects to feeding.

Fig. 4, Fig. 5 show the structure of U-shaped shift fork 55, and the hole on it cooperates with fixed axis 50, and the structure of U-shaped shift fork 60,67 is same as U-shaped shift fork 55.

Fig. 6 illustrates U-shaped shift fork 67,60 and 55, be contained in Z to splined shaft 66, X to splined shaft 61 and Y the position on splined shaft 59.Z is provided with clutch gear 64 to splined shaft 66, clutch 65, and spring 70, U-shaped shift fork 67 is connected with clutch 65.X is provided with clutch gear 63, clutch 62 and U-shaped shift fork 60 and is connected with clutch 62 to splined shaft 61.Y is provided with duplex clutch gear 58, clutch 56 and U-shaped shift fork 55 and is connected with clutch 56 to splined shaft 59.

Use the utility model, control crank 51 driven gears 52 make rack-plate 53 move left and right, drive the feeding operation that U-shaped shift fork 67,60 and 55 just can be selected Z, X, three directions of Y.
