Abstract

The utility model discloses a robot push rod drive shaft assembly which comprises a main shaft, a shaft sleeve, a spring, a stop block and a plug, wherein each of the main shaft and the shaft sleeve comprises an axial blind hole and strip-shaped slots, the main shaft is inserted into the blind hole and can axially move; a through hole communicated with the blind hole is formed in the circumferential surface of the shaft sleeve, the stop block, the spring and the plug are sequentially inserted into the through hole, one end of the stop block is clamped in one strip-shaped slot, and the plug is in sealing connection with the through hole. The robot push rod drive shaft assembly can prevent the main shaft and the shaft sleeve from being separated due to dropping in the carrying process, so that the reassembling procedure is avoided, and time is saved.

Description

A kind of robot pushing bar driving shaft assembly
Technical field
The utility model belongs to a kind of robot accessory field, is specifically related to a kind of robot pushing bar driving shaft assembly.
Background technique
Traditional robot pushing bar driving shaft assembly comprises main shaft and axle sleeve, and described main shaft is directly plugged in axle sleeve, there is no the device that main shaft and axle sleeve interfix, so in handling process, main shaft is stressed easily to be skidded off axle sleeve and separates with axle sleeve, so ressemble again, therefore bothers very much.
Model utility content
(1) technical problem that will solve
The technical problems to be solved in the utility model will prevent that main shaft from separating in handling process with axle sleeve.
(2) technological scheme
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of robot pushing bar driving shaft assembly, comprises main shaft, axle sleeve, spring, limiting stopper and plug; Described axle sleeve and main shaft include respectively an axial blind hole and rectangular groove, described main shaft is plugged in blind hole and can moves axially, the circumferential surface of described axle sleeve includes a through hole being communicated with blind hole, described limiting stopper, spring and plug are plugged in through hole successively, and one end of limiting stopper is connected in rectangular groove, and described plug and through hole are tightly connected.
Described rectangular groove has 4, and taking main shaft as axle center annular uniform.
Described limiting stopper is connected in one of them rectangular groove.
One end of described limiting stopper bottom is the combination between oblique angle, fillet or oblique angle and fillet.
Further also comprise seal ring, described seal ring is arranged between plug and through hole.
(3) beneficial effect
Robot of the present utility model pushing bar driving shaft assembly, by a rectangular groove is set on main shaft, on described axle sleeve, limiting stopper is set, make limiting stopper and rectangular groove clamping, thereby can make main shaft depart from axle sleeve, preventing from dropping in handling process makes main shaft separate with axle sleeve, has therefore avoided the operation of ressembling, and has saved the time.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model robot pushing bar driving shaft assembly;
Fig. 2 is the sectional view of A-A in Fig. 1;
Fig. 3 is the enlarged view of B in Fig. 1;
In figure, 1 is that main shaft, 2 is axle sleeve.3 is that limiting stopper, 4 is that spring, 5 is that plug, 6 is that blind hole, 7 is that rectangular groove, 8 is that through hole, 9 is seal ring.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
A robot pushing bar driving shaft assembly as shown in Figure 1-Figure 3, comprises main shaft 1, axle sleeve 2, spring 4, limiting stopper 3, plug 5 and seal ring 9, described axle sleeve 2 and main shaft 1 include respectively 6 and 4 of axial blind holes taking main shaft 1 as axle center the uniform rectangular groove 7 of annular, described main shaft 1 is plugged in blind hole 6 and can moves axially, the circumferential surface of described axle sleeve 2 includes a through hole 8 being communicated with blind hole 6, described limiting stopper 3, spring 4 and plug 5 are plugged in through hole 8 successively, and one end of limiting stopper 3 is connected in one of them rectangular groove 7, therefore can make main shaft 1 and axle sleeve 2 depart from, prevent from dropping in handling process main shaft 1 is separated with axle sleeve 2, therefore avoided the operation of ressembling, save the time.Three rectangular grooves 7 at other can be arranged on the impurity of blind hole 6 in rectangular groove 7, thereby prevent that main shaft 1 and axle sleeve 2 from blocking.Described plug 5 is tightly connected with through hole 8, described seal ring 9 is arranged between plug 5 and through hole 8, opening plug 5 can be expelled to lubricant oil in this rectangular groove 7 from through hole 8, as the accumulator of lubricant oil, makes robot pushing bar driving shaft assembly carry lubricating function.
One end of described limiting stopper 3 bottoms is the combination between oblique angle, fillet or oblique angle and fillet, in the time that main shaft 1 is inserted into the rear top of blind hole 6 to limiting stopper 3, limiting stopper 3 can be moved up, therefore this structure can be in the situation that main shaft 1 not also be processed, directly axle sleeve 2, spring 4, limiting stopper 3, plug 5 and seal ring 9 are first installed, without first main shaft 1 being inserted, blind hole 6 is interior could install, and has therefore relatively saved the time.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
