The utility model content

The purpose of this utility model is to provide a kind of manipulator that can drive stably on the automatic punching machine to realize reciprocating automatic punching machine cam guide in order to solve above-mentioned the deficiencies in the prior art.

To achieve these goals, the automatic punching machine cam guide that the utility model is designed, comprise cam box and cam pack, described cam box is rectangle, be fixed with two axis of guides between the inwall of the two sides that its length is shorter, two axis of guides are the parallel sided long with its length all, on two axis of guides, all be fixed with two sliding gear mount pads, four sliding gear mount pads are the sphere of movements for the elephants shape and distribute, four sliding gear mount pads that distribute at the sphere of movements for the elephants shape are fixed with two sliding gears, described two sliding gears are all vertical with the axis of guide, center at the bottom of the case of cam box is provided with camshaft hole, described cam pack comprises camshaft, guide plate and cam, camshaft is plugged on the camshaft hole, and between two sliding gears, guide plate is socketed on the camshaft, and be positioned at the top of sliding gear, one end of guide plate runs through the sidewall of cam box, be fixed with two CF bearings at guide plate, described two CF bearings and two sliding gears are corresponding and mutually be slidingly connected one by one, cam also is socketed on the camshaft, and be positioned at guide plate directly over, cooperate for keyway between described cam and the camshaft.

For the impurity dust that reduces in the external environment enters in the cam box, the top of cam box described in the utility model also lid is connected to cover plate, be provided with equally dead eye on the described cover plate, and corresponding with the dead eye of cam box bottom, the camshaft front end runs through the dead eye on the cover plate.

In order to reduce the friction between camshaft and cam box and the cover plate, the protection camshaft prolongs its service life, and the dead eye on the described cam box is embedded with lower ball cover, and the dead eye on the described cover plate is embedded with upper ball cover.

The automatic punching machine cam guide that the utility model obtains, it can drive stably, and the manipulator realization moves back and forth on the automatic punching machine.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

Embodiment 1:

Such as Fig. 1, automatic punching machine cam guide described in Fig. 2 and Fig. 3, it comprises cam box 1 and cam pack, described cam box 1 is rectangle, be fixed with two axis of guides 6 between the inwall of the two sides that its length is shorter, two axis of guides 6 are the parallel sided long with its length all, on two axis of guides 6, all be fixed with two sliding gear mount pads 7, four sliding gear mount pads 7 are the sphere of movements for the elephants shape and distribute, four sliding gear mount pads 7 that distribute at the sphere of movements for the elephants shape are fixed with two sliding gears 8, described two cunning gears 8 are all vertical with the axis of guide 6, center at the bottom of the case of cam box 1 is provided with camshaft hole 101, sidewall at cam box 1 is provided with guide plate mating holes 102, described cam pack comprises camshaft 3, guide plate 5 and cam 4, camshaft 3 is plugged on the camshaft hole 101, and between two sliding gears 8, guide plate 5 is socketed on the camshaft 3, and be positioned at the top of sliding gear 8, the guide plate mating holes 102 that one end of guide plate 5 runs through on the sidewall of cam box 1 arranges, be fixed with two CF bearings 9 at guide plate 5, described two CF bearings 9 and two sliding gears 8 are corresponding and mutually be and be slidingly connected one by one, cam 4 also is socketed on the camshaft 3, and be positioned at guide plate 5 directly over, cooperate for key 13 grooves between described cam 4 and the camshaft 3.

During specific works, camshaft band moving cam is eccentric rotary between two CF cams on the guide plate, so that whole guide plate is realized horizontal reciprocating movement.

CF bearing 9 in above-mentioned is the known prior art of insider, therefore seldom be described in detail at this.

Embodiment 2:

As shown in Figure 4, the automatic punching machine cam guide that the present embodiment provides, its general structure is consistent with embodiment 1, but for the impurity dust that reduces in the external environment enters in the
