[0024] Figure 1 This is a schematic diagram of an adjustable connector error-proof guide pin tooling according to an embodiment of the present invention.
[0025] like Figures 1-5 An adjustable connector error-proof guide pin fixture includes: an upper bracket 1, a lower bracket 2, two spring clamping blocks 3, a first positioning pin 4, a first guide pin mating post 5, a second guide pin mating post 6, and a second positioning pin 7.
[0026] like Figure 3 The first guide pin mating post 5 and the second guide pin mating post 6 are provided with an annular groove in the middle section. The upper end is the clamping end and the lower end is the error-proof guide pin mating end. The upper end includes two sets of parallel planes and a cylindrical surface connecting the two adjacent planes.
[0027] like Figure 1 and 2 The upper bracket 1 and the lower bracket 2 are fixedly connected. The lower bracket 2 is provided with a square through hole that runs vertically through the top and bottom. A spring mounting boss and a positioning pin groove are provided on a pair of side walls of the square through hole from top to bottom. The spring of the spring clamping block 3 is sleeved on the spring mounting boss. The clamping end of the spring clamping block 3 clamps the clamping ends of the first guide pin pairing post 5 and the second guide pin pairing post 6. The first positioning pin 4 and the second positioning pin 7 pass through the positioning pin groove and contact the annular groove in the middle section of the first guide pin pairing post 5 and the second guide pin pairing post 6 to achieve axial positioning.
[0028] like Figure 5 The positioning ends of the first positioning pin 4 and the second positioning pin 7 include two symmetrical cylindrical surfaces for respectively abutting against the annular groove surface of the middle section of the first guide pin mating post 5 and the second guide pin mating post 6.

[0033] Working principle:
[0034] The upper bracket 1 and the lower bracket 2 are connected by rivets. The lower bracket 2 has a positioning pin groove and a spring mounting boss. The first guide pin mating post 5 and the second guide pin mating post 6 are fixed by the spring clamping block 3. Axial positioning is achieved by the first positioning pin 4 and the second positioning pin 7. The lower bosses of the first guide pin mating post 5 and the second guide pin mating post 6 cooperate with the anti-error guide pin.
[0035] During operation, rotate the first guide pin mating post 5 and the second guide pin mating post 6, keeping them roughly aligned with the combined orientation, according to the orientation of the connector's anti-misalignment guide pin boss. Slightly rotate the mating posts to check if the spring clamping block 3 is in contact with the contact plane of the first guide pin mating post 5 and the second guide pin mating post 6. Move the first guide pin mating post 5 and the second guide pin mating post 6 up and down to check if the axial positioning is successful. After checking, align the lower ends of the first guide pin mating post 5 and the second guide pin mating post 6 with the upper ends of the connector's anti-misalignment guide pin to complete the clamping function.
[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should be covered within the protection scope of this utility model.
