Therefore, the present invention is not limited to the specific implementation methods disclosed below.

[0032] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] See also Figure 3 As shown, this embodiment is a pin shaft assembly tool, comprising:

[0034] The tooling and jig section includes a jig base 11;

[0035] The fixture seat 11 is used as a main assembly tool and is used to open the positioning cavity 12 described below;

[0036] The tooling fixture part also includes a positioning cavity 12;

[0037] The positioning cavity 12 is equidistantly opened in the middle of the upper end of the fixture seat 11, and a through opening is penetrated in the middle of the outer end of the bottom end of the positioning cavity 12;

[0038] The positioning cavity 12 is used to position the pin shaft to be assembled, and the through opening matches the through hole on the pin shaft for inserting the split pin;

[0039] Auxiliary assembly part, the auxiliary assembly part includes a fixed magnetic sheet 21, a movable magnetic sheet 22, and a movable column 23;

[0040] The fixed magnetic sheet 21 is fixed to the outer side of the lower end of the fixture seat 11 at an equal distance, and the movable magnetic sheet 22 is arranged on the outer side of the fixed magnetic sheet 21. The movable magnetic sheet 22 and the fixed magnetic sheet 21 are magnetically attracted to each other, and the movable column 23 is symmetrically fixed to the outer end of the movable magnetic sheet 22.

[0041] The fixed magnetic sheet 21 cooperates with the magnetically attracted movable magnetic sheet 22 to separate the two ends of the inserted split pin, and the movable column 23 acts on the movable magnetic sheet 22 to bend one end of the split pin to complete the assembly;

[0042] The auxiliary assembly portion further includes a slide groove 24;

[0043] The slide grooves 24 are symmetrically arranged on both sides of the lower end of the passage, and the protrusions provided in the middle of the upper end of the movable magnetic sheet 22 slide in the slide grooves 24;

[0044] The sliding of the protrusion in the slide groove 24 guides the position of the movable magnetic sheet 22 and reduces the friction generated by the movement;

[0045] The fixed magnetic sheet 21 and the movable magnetic sheet 22 are magnetically attracted to each other and are located in the middle of the lower end of the through hole;

[0046] After being magnetically attracted, it is in the middle, which is conducive to separating the front and rear ends of the inserted split pins;

[0047] Working principle: After the pin to be assembled is placed into the positioning cavity 12, the structural definition of the pin is completed;

[0048] At this time, the split pin can be assembled and inserted. When the split pin passes through the through hole on the pin shaft and moves downward through the through hole, the magnetic fixed magnetic sheet 21 and the movable magnetic sheet 22 are located in the middle of the lower end of the through hole, and the split pin moving downward can be separated into the front and rear ends.

[0049] Next, an outward pulling force is applied to the movable column 23, and the force acts on the movable magnetic sheet 22. The movable magnetic sheet 22 slides in the slide groove 24, and one end of the split pin is bent, thereby completing the insertion and assembly of the split pin on the pin shaft.

[0050] This solution does not require judgment of the bending position, which saves time and effort and improves assembly efficiency.

[0056] The locking column 41 fastens and installs the adjacent set of fixing plates 32 to improve the stability of the structure, and the clamping sleeve 42 installs and fixes the handle 44. By using the handle 44 in conjunction with the locking column 41, the fixture seat 11 can be transported to improve the applicability and functionality of the structure.

[0058] The sleeve connection between the sleeve column 43 and the sleeve opening fixes the handle 44 and the clamping sleeve 42, and the sleeve connection method is convenient for disassembly and assembly of the structure;

[0059] Working principle: When placing the fixture seat 11, the fixing plate 32 is placed inside the opening 31 in advance, and the fixing bolt 33 is placed at a suitable position in the opening 31, and the thread penetrates and extends out of the upper part of the fixing plate 32, the fixing plate 32 is fixed, and the lower end of the fixing plate 32 is in contact with the contact surface;

[0060] Next, a set of locking posts 41 are threaded through the lower end of the fixing plate 32 to lock the lower part of the fixing plate 32;

[0061] If the fixture seat 11 is to be transported and moved, the fixture seat 11 can be inverted, and a set of clamping sleeves 42 can be clamped on the middle part of the locking column 41, and the sleeve column 43 and the sleeve mouth are used together to clamp the inner side of the clamping sleeve 42 with the handle 44, and the fixture seat 11 can be transported by the handle 44;

[0062] This solution improves the applicability and functionality of the structure to meet different usage requirements.
