[0022] Therefore, the driving assembly is started, the lock block 4 on the supporting column is inserted into the lock groove 5 under the driving of the driving assembly, the position of the lock block 4 is limited by the lock groove 5, thereby the position of the fixing unit 1 is limited, the possibility of position deviation of the fixing unit 1 is reduced, the stability of the position of the fixing unit 1 on the assembly station is improved, the accuracy of the position of the insulator body inserted into the steel cap is improved, and the production quality and production efficiency of the insulator structure are improved.
[0023] Referring to Figure 1 and Figure 2, the driving assembly comprises a telescopic cylinder 7 arranged on the rack, the output end of the telescopic cylinder 7 is hinged with a connecting rod 8, the end of the connecting rod 8 away from the telescopic cylinder 7 is arranged on the connecting column 3, in the embodiment of the application, the end of the connecting rod 8 away from the telescopic cylinder 7 is provided with a mounting hole matched with the connecting column 3, the connecting column 3 passes through the mounting hole and is in contact with the hole wall of the mounting hole, an open slot is arranged on the hole wall of the mounting hole, the end of the connecting rod 8 away from the telescopic cylinder 7 is divided into a first connecting block 11 and a second connecting block 11 through the open slot, the first connecting block 11 and the second connecting block 11 can be connected through the bolt connection mode, so as to fix the connecting rod 8 on the connecting column 3. Therefore, the telescopic cylinder 7 is started, the connecting rod 8 at the output end of the telescopic cylinder 7 is driven to extend, the end of the connecting rod 8 away from the telescopic cylinder 7 drives the connecting column 3 to rotate, the lock block 4 is inserted into the lock slot 5, and the positioning and fixing of the position of the fixing unit 1 are realized.
[0024] With reference to Figure 1 and Figure 2 , the lock block 4 is rotatably connected with a positioning roller 16 matched in size with the lock slot 5, the positioning roller 16 is inserted into the lock slot 5, the direct friction between the lock block 4 and the lock slot 5 is converted into rolling friction through the positioning roller 16, the abrasion between the lock block 4 and the lock slot 5 is reduced, and therefore the lock block 4 is conveniently and smoothly inserted into the lock slot 5.
[0025] With reference to Figure 1 and Figure 2 , the lock block 4 comprises a first supporting block 9, one end of the first supporting block 9 is fixedly connected with a connecting block 11, the end of the connecting block 11 away from the first supporting block 9 is fixedly connected with a second supporting block 10, there is a gap between the first supporting block 9 and the second supporting block 10 and the connecting column 3 is located between the first supporting block 9, the second supporting block 10 and the connecting block 11, the first supporting block 9 and the second supporting block 10 are oppositely arranged, the first supporting block 9, the second supporting block 10 and the connecting block 11 form an annular structure, and the first supporting block 9 and the second supporting block 10 are connected through a fixing structure. The fixing structure comprises a mounting bolt sequentially penetrating through the second supporting block 10 and the first supporting block 9, an installation nut is threadedly connected to the outer edge of the mounting bolt, and the first supporting block 9 is abutted between the installation nut and the mounting bolt.
[0026] Therefore, when it is necessary to adjust the position of the lock block 4 on the connecting column 3, the operator dismounts the mounting bolt, so that the lock block 4 can be displaced on the connecting column 3, after being adjusted to a suitable position, the mounting bolt is mounted on the lock block 4 through the bolt connection mode, so as to realize the locking and fixing of the position of the lock block 4, improve the flexibility of the position of the lock block 4, and facilitate the fine adjustment of the position of the lock block 4 according to the actual situation on site.
