[0029] Example:

[0030] The following is combined with Figure 1-4 The present invention is described in further detail.

[0031] The embodiment of the present invention discloses a special grounding wire bolt and nut assembly device for automobiles. Figure 1 and Figure 2 , 3, including a workbench 1, a bolt mechanism 2 is provided on the top of the workbench 1, the bolt mechanism 2 includes a fixing frame 3, the bottom of the fixing frame 3 is fixedly connected to the top of the workbench 1, and a reciprocating cylinder 4 is provided on the inner wall of the top of the fixing frame 3, and a supporting plate 5 is fixedly connected to the driving end of the bottom of the reciprocating cylinder 4, the fixing frame 3 is an "L"-shaped plate structure, and the end of the supporting plate 5 facing the fixing frame 3 does not contact the side wall of the fixing frame 3, and the end of the supporting plate 5 away from the fixing frame 3 is provided with a clamping groove 6, and an upper block 7 is provided above the clamping groove 6, and a positioning groove 8 is provided at the center of the bottom end of the upper block 7, and a connecting plate 9 is provided on the outer side of the top of the upper block 7, and the connecting plate 9 is located at one end of the reciprocating cylinder 4. The bottom of the connecting plate 9 is fixedly connected to the top of the supporting plate 5, and the inner cavity at the top of the connecting plate 9 is movably sleeved with a movable rod 10, and the bottom of the movable rod 10 is fixedly connected to the top of the upper block 7, and a spring 11 is provided on the outer side of the bottom end of the movable rod 10, one end of the spring 11 is fixedly connected to the top of the upper block 7, and the other end of the spring 11 is fixedly connected to the inner wall at the top of the connecting plate 9, and the bolt mechanism 2 is provided with eight groups, and the eight groups of bolt mechanisms 2 are evenly distributed on the top of the workbench 1, and the sides of the eight groups of bolt mechanisms 2 are provided with nut mechanisms 12, and the nut mechanism 12 includes a lower block 13, and the lower block 13 is located below the card slot 6, and the lower block 1 A placement groove 14 is provided at the top of the block 3, and a through hole 15 is provided at the center of the bottom of the placement groove 14. The through hole 15 is provided at the bottom of the lower block 13. The positioning groove 8 and the placement groove 14 are both regular hexagonal groove structures, and the centers of the positioning groove 8, the placement groove 14 and the through hole 15 are on the same reference axis. By setting the positioning groove 8 and the placement groove 14, the regular hexagonal groove structures designed by the two can be used to facilitate the matching and placement of the bolt head and the nut to be assembled, so that the bolt will not rotate randomly after being positioned, and the nut can be synchronously rotated with the lower block 13 after being positioned, so as to facilitate the formation of the bolt in the later stage. When docked and assembled with the nut, the bolt moves downward and the nut rotates in a mutually assembled state. The through hole 15 is set, and its main body is a circular groove structure, and the diameter of the through hole 15 is larger than the diameter of the threaded part on the assembled bolt, so as to facilitate the later extraction and separation of the bolt and nut after the assembly is completed, and improve the flexibility of the overall equipment. A driving arm 16 is fixedly installed at the bottom of the lower block 13, and the driving arm 16 is located on the outside of the bottom of the through hole 15, and the driving arm 16 is a "U"-shaped block structure. The center of the bottom of the driving arm 16 is movably connected to a small motor 17 through a rotating shaft, and the bottom of the small motor 17 housing is fixedly connected to the top of the workbench 1.

[0032] See also Figure 1 and Figure 4A bottom plate 18 is provided at the center below the workbench 1. A sleeve 19 is fixedly connected to the center of the top of the bottom plate 18 and the center of the bottom of the workbench 1. The inner walls of the two sets of sleeves 19 are movably connected to pillars 20 through bearings. The pillars 20 are circular cylindrical structures. A first gear 21 is fixedly sleeved on the outer wall of the pillars 20. The side end of the first gear 21 is meshed with a second gear 22. The center of the bottom of the second gear 22 is movably connected to a drive motor 23 through a rotating shaft. The bottom of the housing of the drive motor 23 is fixedly connected to the top of the bottom plate 18. The bottom plate 18 and the pillar 20 can effectively support the whole, and cooperate with the sleeve 19, the first gear 21, the second gear 22 and the drive motor 23 to effectively drive the workbench 1 and the eight sets of bolt mechanisms 2 and nut mechanisms 12 thereon to rotate slowly and at a uniform speed, so that the whole can cooperate with the operation of two staff members to form a pipeline assembly work, thereby improving the assembly efficiency of bolts and nuts, and overcoming the disadvantages of traditional manual assembly.

[0033] The implementation principle of the automobile grounding wire bolt and nut assembly equipment of the embodiment of the present invention is as follows: during use, two operators are required, and they work at opposite positions of the workbench 1 respectively. During assembly, the driving motor 23 is started, so that the second gear 22 and the first gear 21 cooperate with each other, and indirectly drive the workbench 1 and the eight groups of bolt mechanisms 2 and nut mechanisms 12 thereon to rotate slowly and evenly. While starting each group of small motors 17, a staff member places the nut to be assembled inside the placement groove 14, and clamps the bolt to be assembled on the inner side of the clamping groove 6. While clamping, first pull the upper block 7 upward, at this time, the spring 11 produces compression deformation, and then the hexagonal top of the bolt is clamped on the inner side of the positioning groove 8. The bolt is positioned at one end of the support plate 5 close to the clamping groove 6 under the action of the loosening of the upper block 7, thereby completing a group of bolts and nuts. After the placement and positioning work, the bolt mechanism 2 and the nut mechanism 12 are rotated to the side with the workbench 1, and the reciprocating cylinder 4 arranged inside the bolt mechanism 2 performs a round of downward and upward reciprocating motion while rotating, and the reciprocating cylinder 4 moves downward, so that the placed bolts and the passively rotating nuts are docked and spirally assembled, and the reciprocating cylinder 4 moves upward to pull the assembled bolts and nuts synchronously, so that the nuts are separated from the placement groove 14. When the group of assembled bolts and nuts rotates in front of another staff member, the staff member holds the bolts and squeezes upward, so that the spring 11 is deformed again, and the bolts are separated from the positioning groove 8 and the clamping groove 6. At this time, the extraction of a group of assembled bolts and nuts is completed, and eight groups of bolt mechanisms 2 and nut mechanisms 12 are operated in this assembly line manner to achieve efficient assembly of bolts and nuts.

[0034] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
