In order to avoid the movement of the mechanical arm 1 along the axial direction of the rotating shaft 2 between the mounting gaps, the offset of the mechanical arm 1 is prevented, the mounting precision of the mechanical arm 1 is improved, and further the influence on the positioning precision of the tail end (the mounting end or the carrying end) of the mechanical arm 1 due to the position offset of one end of the mechanical arm 1 is weakened, so that the mounting or carrying precision is improved. This effect is more pronounced as the radius of gyration of the arm 1 is larger, and a small deflection at one end of the arm 1 will cause a large error at the other end of the arm 1. In order to solve the above problems, referring to fig. 1 to 3 of the drawings, the present application provides a mechanical arm anti-offset structure for limiting the offset of a mechanical arm 1 along the axial direction of a rotating shaft 2. For the sake of clearly describing the structure and composition of the anti-offset structure of the mechanical arm, it will be described with reference to a usage scenario, it will be understood that the usage scenario is not a limitation of the anti-offset structure of the mechanical arm, and the usage scenario is as follows: one end of the mechanical arm 1 is arranged between two oppositely arranged side plates 3 through a rotating shaft 2 and can rotate relative to the side plates 3. This arm anti-migration structure includes:
the threaded studs 4 are provided with threads with opposite screwing directions at two ends, and the threads at two ends of the threaded studs 4 are screwed in or out simultaneously when the threaded studs 4 are screwed in one direction, so that the threaded studs 4 are convenient to mount and dismount;
the rotating shaft 2 penetrates through one end of the mechanical arm 1 and two side plates 3 which are oppositely arranged on two sides of the mechanical arm 1, and the mechanical arm 1 can rotate relative to the side plates 3 through the rotating shaft 2;
the fixing piece 5 is used for connecting the stud 4 with the rotating shaft 2, the fixing piece 5 is provided with a screw hole 51 and a jack 52, and the axial direction of the screw hole is parallel to the axial direction of the jack 52;

It will be appreciated that the purpose of abutment of the fixing member 5 with the rotating shaft 2 is to limit the relative movement of the fixing member 5 in the direction approaching the side plate 3, and when there is a relative movement space between the side plate 3 and the rotating shaft 2 in the axial direction of the rotating shaft 2, it is necessary to abut the fixing member 5 with the side plate 3 instead of abutting the fixing member 5 with the rotating shaft 2. In a conventional case, there is no relative movement space between the rotation shaft 2 and the side plate 3 in the axial direction of the rotation shaft 2.
In other embodiments, the two side plates 3 may be further provided with a sleeve 9 on one side close to the corresponding fixing member 5, the sleeve 9 is sleeved on the rotating shaft 2, the sleeve 9 is provided with a jack (not shown in the figure) along the radial direction of the sleeve 9, the rotating shaft 2 is provided with a slot (not shown in the figure) corresponding to the jack, and the sleeve 9 is connected with the rotating shaft 2 through the cooperation of the jack and the slot.
In this embodiment, the sleeve 9 abuts against the side surface of the corresponding side plate 3, and the axial relative displacement between the sleeve 9 and the rotating shaft 2 is limited by the connection between the sleeve 9 and the rotating shaft 2, so that the relative displacement between the rotating shaft 2 and the side plate 3 is limited, in other words, the mounting base is clamped between the two sleeve 9, and no axial relative movement exists between the mounting base and the rotating shaft 2. In this embodiment, the sleeve 9 may be a sliding sleeve or bushing.
The anti-offset structure is ingenious in design and simple in structure, can limit the relative movement between the mechanical arm 1 and the base, prevents the mechanical arm 1 from axially offsetting, reduces the influence on the positioning precision of the tail end of the mechanical arm 1, and ensures the mounting or carrying precision.
It should be noted that, when the mechanical arm 1 is mounted on the outer sides of two oppositely disposed side plates 3, and the mechanical arm 1 and the rotating shaft 2 do not move axially relatively, one end of the stud 4 is mounted on the side plate 3, the other end is in threaded connection with the fixing piece 5, and the insertion hole 52 of the fixing piece 5 is in rotational connection with the rotating shaft 2 and abuts against the rotating shaft 2.
Referring to fig. 1 to 3 of the drawings, in one embodiment, the stud 4 may also be connected to the arm 1 by a mounting nut 7, the mounting nut 7 being mounted to the arm 1 by welding or screwing, the other end of the mounting nut 7 being screwed to the end of the stud 4 remote from the fixing member 5, the mounting nut 7 fixedly mounting the stud 4 to the arm 1, that is, the stud 4 is not directly mounted to the arm 1 but indirectly connected to the arm 1 by the mounting nut 7.

The mounting nut 7 can also play the role of a wearing part, is convenient to replace, and reduces the maintenance and repair cost of the anti-offset structure.
Referring to fig. 1 to 3 of the drawings, in order to provide an operation position when screwing the stud bolt 4, to avoid damage to the thread of the stud bolt 4 when clamping the stud bolt 4, the normal use of the stud bolt 4 is affected, and in one embodiment, the middle portion of the stud bolt 4 is provided with a screwing portion 41 to facilitate screwing the stud bolt 4.
In one embodiment, both ends of the stud bolt 4 are pierced with lock nuts 6 which are screw-fitted with both ends of the stud bolt 4. Through setting up lock nut 6, can utilize lock nut 6 to lock stud 4 after stud 4 installs in place, avoid the not hard up of stud 4 even drop.
Referring to fig. 3 of the drawings, it can be understood that a bushing 8 is arranged between the end of the rotating shaft 2 and the jack 52, and by arranging the bushing 8, the rotation friction between the rotating shaft 2 and the fixing piece 5 can be reduced, the abrasion risk of the rotating shaft 2 and the fixing piece 5 is reduced, and the influence on the precision of the mechanical arm 1 is reduced.
In the present embodiment, the bushing 8 is preferably an oil-free bushing 8, and the oil-free bushing 8 is convenient for maintenance and can reduce maintenance cost.
In the present embodiment, the rotary shaft 2 and the stud bolts 4 are preferably made of metals having the same thermal expansion coefficient.

The relevant features of the anti-offset structure of the mechanical arm are described above and will not be described herein.
It will be appreciated that in order to facilitate replacement and to damage the low cost components of the arm anti-migration structure in the first place, it is preferable that the material strength of both the arm 1 and the stud 4 be greater than the material strength of the mounting nut 7. Therefore, the damage risk of the joint of the mechanical arm 1 and the mounting nut 7 and the damage risk of the joint of the stud 4 and the mounting nut 7 are smaller than the damage risk of the mounting nut 7, the mounting nut 7 is damaged at first, the mounting nut 7 is low in production cost and convenient to replace, and the anti-deviation structure and the maintenance cost of the mechanical arm 1 can be reduced.
