Description

A kind of outrigger shaft

Technical field

The utility model relates to the outrigger shaft field of automotive automation press machine robot end axle, especially relates to a kind of outrigger shaft.

Background technology

Robot of automotive automation press workshop is used widely, transmission in actual production between station often needs extension arm to realize the function of carrying, transmission, rotation, in order to increase the opereating specification of robot, must increase outside transmission mechanism and reach productive temp needs simultaneously.

At present, the outrigger shaft of robot end's axle of employing mostly is rigidity, and can not rotate, when producing large-scale plate, the stability of outrigger shaft and rigidity a little less than.Meanwhile, the non-rotatable property due to outrigger shaft causes rotary space required in outrigger shaft work and handling process larger.

Utility model content

The utility model proposes a kind of outrigger shaft, solved current outrigger shaft poor stability, and non-rotatable problem.

The technical solution of the utility model is achieved in that

An outrigger shaft, the rotating junction that it comprises principal arm, is placed in the terminal shaft connecting groove of principal arm one end and is placed in the principal arm other end; Described terminal shaft connecting groove, be provided be rotationally connected dish, with described in be rotationally connected the clutch shaft bearing of dish mechanical connection and the connecting rod that connects principal arm and be connected with described clutch shaft bearing;

Described rotating junction comprise the second bearing of being connected with described connecting rod, adpting flange and with the roller bearing of described adpting flange mechanical connection, the second described bearing is connected with described adpting flange by earrings.

Wherein, preferably, the periphery of described terminal shaft connecting axle groove is provided with connecting hole.

Preferably, clutch shaft bearing and the second bearing are oscillating bearing.

Preferably, described adpting flange is for being rotationally connected flange.

Preferably, described roller bearing is crossed roller bearing.

Preferably, described principal arm one side is provided with retainer ring.

The beneficial effects of the utility model are as follows:

1) rotation of robot end's axle can be with dynamic bearing and connecting rod, the connecting rod that connects principal arm is rotationally connected flange, thereby the rotating function that makes terminal shaft is transferred to described outrigger shaft, solved the larger problem of requisite space of current robot punch line upper plate carrying.

2) the design has realized the relatively large plate of carrying in less space, has improved process velocity and has reduced production cost.

Wherein, 1. principal arm, 2. terminal shaft connecting groove, 3. rotating junction, is 4. rotationally connected dish, 5. clutch shaft bearing, 6. connecting rod, 7. adpting flange, 8. earrings, 9. roller bearing, 10. the second bearing, 11. connecting holes, 12. retainer rings.

The specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.

1 one kinds of outrigger shafts of embodiment

As shown in Figure 1,2 and 3, a kind of outrigger shaft, the rotating junction 3 that it comprises principal arm 1, is placed in the terminal shaft connecting groove 2 of principal arm one end and is placed in the principal arm other end; Described terminal shaft connecting groove 2, its be provided be rotationally connected dish 4, with described in be rotationally connected clutch shaft bearing 5 and perforation principal arm the connecting rod 6 that is connected with described bearing of dish mechanical connection; Described rotating junction 3 comprise the bearing 10 that is connected with described connecting rod 6, adpting flange 7 and with the roller bearing 9 of described adpting flange mechanical connection, the second described bearing 10 is connected with described adpting flange 7 by earrings 8.Described principal arm 1 one sides are provided with retainer ring 12.

2 one kinds of outrigger shafts of embodiment,

As shown in Figure 1, it comprises the structure of outrigger shaft described in embodiment 1, and the periphery of wherein said terminal shaft connecting axle groove 2 is provided with connecting hole 11.

During concrete enforcement, wherein, the clutch shaft bearing 5 that is located at described terminal shaft connecting groove 2 is oscillating bearing with the second bearing 10 that is arranged on described rotating junction 3.

During concrete enforcement, described adpting flange 7 is for being rotationally connected flange, and described roller bearing 9 is crossed roller bearing.

Wherein, as shown in Figure 1,2 and 3, terminal shaft connecting groove 2 is connected by connecting hole 11 standing parts with robot end's axle, simultaneously the terminal shaft of robot and be rotationally connected and coil 4 and be connected.When the terminal shaft of robot rotates, drive and be rotationally connected clutch shaft bearing 5 and connecting rod 6 on dish 4, by connecting rod 6 by the second bearing 10 rotate with roller bearing 9 on adpting flange 7.The terminal shaft rotating function of robot can have been moved on corresponding adpting flange 7 like this to the rotary space of minimizing work carrying.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
