[0006] Furthermore, the support base is provided with an arc groove and a positioning groove. The arc groove is used to support and position the insulator, and the positioning groove is used to position the pin.

The pin is a T-shaped pin, and the T-head of the pin cooperates with the positioning groove.

[0008] Furthermore, one side of the support base relative to the positioning groove is an open structure, and an insertion hole is provided on the open side, into which the limiting pin is inserted.

[0009] Furthermore, the limiting pin is a tapered pin, with the smaller diameter end close to the positioning pin shaft.

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] like Figures 1 to 3 As shown, this utility model discloses an insulator cotter pin assembly device, comprising an insulator 1, a cotter pin 2, and a pin shaft 3. The insulator 1 has a connecting lug 11 at its end, and the pin shaft 3 is inserted into the connecting lug 11. This utility model device is used to assist in assembling the cotter pin 2 onto the pin shaft 3.

[0017] This device includes a support frame 4, a support base 5, and a limiting pin 6. The support base 5 is fixed on the support frame 4, the insulator 1 is supported on the support frame 4, the connecting lug 11 is supported inside the support base 5, and the limiting pin 6 is inserted into the support base 5. Moving the limiting pin 6 and inserting it into the pin hole of the pin shaft 3 achieves circumferential positioning of the pin shaft 3.

[0018] The support frame 4 in this utility model consists of two columns arranged at intervals. Each column has an arc groove at its top to support the insulator 1 and ensure the stability of the insulator during assembly.

[0019] The support base 5 is rectangular in shape and has an arc groove and a positioning groove. The arc groove is coaxial with the arc groove at the top of the column and is also used to support and position the insulator 1. The positioning groove is used to position the pin 3.

[0020] The upper surface of the support base 5 is provided with an open rectangular support groove. The arc groove 51 and the positioning groove 52 are respectively provided on two adjacent side walls in the rectangular support groove. The pin 3 is a T-shaped pin. The T-head of the pin cooperates with the positioning groove 52. This design can accurately position the pin and provide an accurate reference for the assembly of the cotter pin.

[0021] The support base 5 has an open structure on one side relative to the positioning groove 52. An insertion hole 53 is provided on this open side. The limiting pin 6 is inserted into the insertion hole. By moving the limiting pin 6, it is inserted into the pin hole of the pin shaft 3, thereby achieving circumferential positioning of the pin shaft 3, preventing the pin shaft from rotating when assembling the cotter pin, and ensuring that the cotter pin can be smoothly assembled into place.

[0022] The limiting pin 6 is a tapered pin, with the smaller diameter end close to the positioning pin shaft 3. This tapered design helps the limiting pin to be inserted into the pin hole of the pin shaft more smoothly, and at the same time provides a more stable positioning effect after insertion.

[0023] The limiting pin 6 is provided with a positioning step 61. The positioning step 61 can limit the insertion of the limiting pin after it has been inserted to a certain depth, preventing the limiting pin from being over-inserted and ensuring the fit accuracy between it and the pin shaft. In addition, after the limiting pin 6 is inserted into the insertion hole 53, when the limiting pin 6 is released, the limiting pin 6 falls due to its own weight and is supported on the support base 5 by the positioning step 61.

[0024] In the actual assembly process, the pin 3 is first inserted into the connecting lug 11, and the insulator 1 is placed on the support frame 4, with its connecting lug 11 positioned within the rectangular support groove of the support base 5. The T-head of the pin 3 is inserted into the positioning groove 52 of the support base 5. Next, the limiting pin 6 is moved upward, and its smaller diameter end is gradually inserted into the pin hole of the pin 3 until the positioning step 61 contacts the support base 5, thereby achieving circumferential positioning of the pin 3. Finally, the cotter pin 2 is inserted into the pin 3, and then the cotter pin 2 is pressed down, pushing out the limiting pin 6 inserted into the pin hole through the cotter pin 2. Finally, the open end of the cotter pin 2 is opened using a tool to complete the cotter pin assembly.

[0025] This device, through the cooperation of the support frame, support base, and limit pin, effectively solves the problems existing in the assembly of insulator cotter pins in the prior art, improves assembly efficiency and accuracy, reduces the labor intensity of operators, and has good practicality and reliability.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
