Description

Connection structure of semi-separated steering rack pull rod Technical Field The utility model relates to the technical field of automobile parts, in particular to a connecting structure of a semi-separated steering rack pull rod. Background In the structure of the automobile steering gear, the rack and the tie rod ball seat are directly assembled together through the threaded hole. In the production assembly process, the rack and the pull rod ball seat have higher tightening torque requirements, and the situation that the rack and the pull rod ball seat are not assembled and tightened in place possibly exists. Therefore, a connecting structure of a semi-separated steering rack pull rod is needed to be designed, so that the assembly difficulty of a rack and a pull rod ball seat is simplified and reduced, and the problem that the rack is possibly not screwed in place in the assembly process is solved. Disclosure of Invention The utility model aims to overcome the defects of the prior art, provides a connecting structure of a semi-separated steering rack pull rod, so as to simplify and reduce the assembly difficulty of a rack and a pull rod ball seat and solve the problem of possibly out-of-place screwing in the assembly process. In order to achieve the above purpose, the utility model provides a connecting structure of a semi-separated steering rack pull rod, which comprises a rack, a pull rod ball seat and a fastener, wherein a positioning groove is arranged in the center of the tail of the rack, a boss is arranged at one side of the tail of the rack, a positioning block is arranged at the head of the pull rod ball seat, the end part of the positioning block is inserted into the positioning groove, the other side of the tail of the rack is inserted into a notch at the end part of the positioning block, a horizontally arranged guide plane is arranged at the joint of the positioning block and the pull rod ball seat, the guide plane and the end surface of the pull rod ball seat respectively support against two surfaces of the boss, and the fastener is fixed with the boss after penetrating through the positioning block. The fastener comprises a bolt and a pin. The axial direction of the fastener is perpendicular to the axial direction of the rack. The positioning block and the pull rod ball seat are of an integrated structure. The boss and the rack are of an integrated structure. Compared with the prior art, the utility model realizes plane guiding and positioning through the matching of the racks and the pull rod ball seat, realizes the fixation of the racks and the pull rod ball seat through the connecting piece, simplifies the installation process, reduces the assembly difficulty and is also convenient for subsequent disassembly and maintenance. Drawings Fig. 1 is a schematic structural view of the present utility model. Detailed Description The utility model will now be further described with reference to the accompanying drawings. Referring to fig. 1, the utility model relates to a connecting structure of a semi-separated steering rack pull rod, which comprises a rack, a pull rod ball seat and a fastener, wherein a positioning groove 11 is arranged in the center of the tail of the rack 1, a boss 12 is arranged on one side of the tail of the rack 1, a positioning block 21 is arranged at the head of the pull rod ball seat 2, the end part of the positioning block 21 is inserted into the positioning groove 11, the other side of the tail of the rack 1 is inserted into a notch at the end part of the positioning block 21, a horizontally arranged guide plane 211 is arranged at the joint of the positioning block 21 and the pull rod ball seat 2, the guide plane 211 and the end surface of the pull rod ball seat 2 respectively support against two surfaces of the boss 12, and the fastener 3 passes through the positioning block 21 and is fixed with the boss 12. The fastener 3 comprises a bolt and a pin. In order to ensure the connection of the positioning block 21 and the boss 12, the axial direction of the fastener 3 is perpendicular to the axial direction of the rack 1. In order to ensure the connection strength, the positioning block 21 and the pull rod ball seat 2 are of an integrated structure. The boss 12 and the rack 1 are of an integral structure. During installation, the rack 1 and the pull rod ball seat 2 are guided through the guide plane 211, after the positioning block 21 at the head of the pull rod ball seat 2 is completely inserted into the positioning groove 11 of the rack 1, the pull rod ball seat 2 is continuously pushed forward, so that a notch of the positioning block 21 abuts against the rack 1, positioning in other directions except the axial direction of the rack 1 is completed, and after the fastener 3 is inserted into the positioning block 21 and the boss 12 are completely fixed, positioning in the axial direction of the rack is completed. According to the utility model, the assembly requiremen
