Just, easy to maintain, greatly improve robot working efficiency.
Description of the drawings
Fig. 1 is the structural schematic diagram of preferred embodiment of the present invention.
Specific implementation mode
The present invention is discussed in detail with reference to Fig. 1：
The feeder of welding robot, including robot forearm 1 and manipulator 2, manipulator are cut with scissors by wrist 4 and forearm
It connects, the wrist includes rotatable hollow rotating shaft 42, and the radial side of the rotating shaft is fixedly connected with the manipulator, machinery
Hand connects welding gun 6, and the radial other side of rotating shaft and the forearm are hinged, by driving rotating shaft rotation, can drive manipulator
Rotation, can drive manipulator to swing by the swing of forearm, ensure that welding gun is in optimum welding position；The manipulator is hollow
Manipulator, the high pressure gas for flowing into the rotating shaft inner cavity 43 is delivered to the welding gun through manipulator inner cavity, to meet machine
The air supply requirement of people's spot welding system.
The drive of high-pressure gas manipulator of the manipulator inner cavity of the present invention elongates or shortens.Specifically, manipulator 2 includes
Hollow shell 21 and it is arranged in the shell inner cavity 22 and front end is by the closed hollow inner casing 23 of cover board 3, the welding gun is mounted on
On cover board, cover board is equipped with the stomata 31 being connected to inner casing inner cavity, which can be connected to by tracheae 32 with the air inlet of welding gun；
The shell inner cavity 22 and inner casing inner cavity 24 constitute the closed manipulator inner cavity 25, the manipulator inner cavity and the rotating shaft
Inner cavity is connected to, and the inner casing is by the way that the air pressure of intracavitary in the manipulator is extended or retraction shell inner cavity.In the welding process, such as
It need to be supplied to welding gun, need to only open the stomata on cover board, gas is made to enter welding gun through air inlet, it is simple to operate.
The rotating shaft side wall offers through-hole 41, and rotating shaft inner cavity is connected to by the through-hole with the manipulator inner cavity；
It is equipped with a spring 5 in the manipulator inner cavity 25, which connect with the cover board, the other end and the rotating shaft side wall
Connection；In the welding process, when welding gun farther out from pad when, high-pressure air source enters machine from rotating shaft inner cavity by the through-hole
Tool hand inner cavity increases the air pressure of intracavitary in manipulator so that inner casing stretches out shell under gas pressure, to drive welding gun close
Pad, while spring extends；If welding gun is too close from pad, the gas of intracavitary can be from through-hole through shaft inner cavity in manipulator
It returns at air source, the air pressure reduction of intracavitary, spring-return power overcome the gas pressure of intracavitary in manipulator, makes inner casing in manipulator
Gradual retraction shell inner cavity, to make welding gun be in best welding position.Preferably, in 22 inner wall of the shell inner cavity
Several grooves 221 are opened up along its length, and the inner casing outer wall is equipped with several sliding blocks 241, and each sliding block stretches into corresponding groove
It is interior and can be moved along groove；In the process that inner casing extends and retracts, sliding block moves the accurate movement, it can be achieved that inner casing along groove；
Sealing strip 222 is provided in groove described in each along its length, ensures the leakproofness of manipulator inner cavity.
It is provided for the embodiments of the invention technical solution above to be described in detail, specific case used herein
The principle and embodiment of the embodiment of the present invention are expounded, the explanation of above example is only applicable to help to understand this
The principle of inventive embodiments；Meanwhile for those of ordinary skill in the art, embodiment according to the present invention, in specific embodiment party
There will be changes in formula and application range, in conclusion the content of the present specification should not be construed as limiting the invention.
