Description

Copper bush installation equipment and installation method Technical Field The invention relates to the technical field of riveting equipment, in particular to copper bush installation equipment and an installation method. Background In various valve body constructions for controlling the flow of liquids or gases, rotatable rotary vanes are typically provided. The rotary vane is generally rotatably connected to a perforated bracket on the valve body through a rotary shaft. In order to reduce frictional wear between the rotating shaft and the rotating hole of the perforated support, extend the service life and improve the rotation stability, it is generally necessary to rivet a copper sleeve (copper sleeve) in the rotating hole of the perforated support to form a wear-resistant mating interface. Therefore, in the valve body production process, the installation and riveting precision of the copper bush directly influences the service performance of the rotary blade and the quality of the whole machine. The existing copper bush riveting equipment mostly adopts a semi-automatic or full-automatic structure, and a support with holes for a copper bush to be riveted is intermittently conveyed to a riveting station through a conveying mechanism, so that press fitting and riveting forming of the copper bush are completed at the station. The equipment has higher requirements on conveying precision and positioning stability while improving production efficiency. However, the existing riveting equipment has the common contradiction that, on one hand, in order to ensure the straightness and the direction consistency of the perforated support in the conveying process, the conveying mechanism is usually kept in continuous contact with the perforated support, and the perforated support is guided and driven through structures such as rollers, clamping blocks or guide rails, so that continuous and stable conveying of all supports in the same reference direction is ensured. However, during the riveting process, axial pressure needs to be applied to the copper bush and the support with holes so as to realize plastic deformation and fixation of the copper bush in the rotating holes. And the pressure generated by riveting is transmitted to the conveying mechanism, so that the conveying component is easy to generate elastic deformation, looseness or abrasion, and the follow-up conveying precision and the equipment stability are further affected. On the other hand, if the conveying mechanism is not adversely affected by the caulking pressure, the conveying mechanism may be separated from the perforated support before caulking, and an independent clamping mechanism may be separately provided to position and clamp the perforated support. However, the conveyance mechanism and the clamping mechanism are required to repeatedly switch between the contact state and the clamping state, so that minute angular displacement or positional deviation is likely to occur, the original linear conveyance reference is destroyed, the consistency of the conveyance direction is reduced, and the riveting position accuracy is further affected. Therefore, the conventional riveting equipment is difficult to realize that the adverse effect of riveting force on a conveying mechanism is effectively reduced while the stable and accurate conveyer belt hole support is ensured. Disclosure of Invention The invention aims to provide copper bush installation equipment and an installation method, which solve the problem that the conventional riveting equipment is difficult to realize that the adverse effect of riveting force on a conveying mechanism is effectively reduced while stable and accurate conveying belt hole supports are ensured. To achieve the purpose, the invention adopts the following technical scheme: The copper bush mounting equipment comprises a rack and conveying and positioning mechanisms arranged on the rack, wherein a riveting station is arranged on the rack, the riveting station is positioned on two sides of the riveting station along a first direction, and at least two groups of conveying and positioning mechanisms are symmetrically arranged; the conveying and positioning mechanism of any group comprises a driving assembly and a positioning assembly which are arranged at intervals along the conveying direction of the support with the holes; The driving assembly comprises a driving roller and a first limiting roller which are arranged at intervals along a second direction and are rotationally connected with the rack, the positioning assembly comprises a bearing roller and a second limiting roller which are arranged at intervals along the second direction and are rotationally connected with the rack, and the first limiting roller and the second limiting roller can move and be fixed along the second direction; The driving roller and the bearing roller are always abutted to the perforated bracket and are positioned on the same side, and the first limi
