Technical Field
The invention relates to a pinch roller mechanism for friction welding of aluminum profiles, in particular to a pinch roller mechanism for production welding of a battery replacement box body of a new energy automobile, and belongs to the technical field of aluminum profile welding.
Background
Along with the increasing severity of energy crisis and environmental pollution, new energy automobiles are more and more emphasized in various countries in development, particularly pure electric automobiles have the characteristics of zero emission, low noise, high energy efficiency and the like, and are one of ideal energy-saving and environment-friendly automobile types.
The battery is the core part of electric automobile, because the battery integration that adopts, must install the battery to the battery box in, what adopt at present is panel beating material power battery box. Although the sheet metal box body can meet the design standard requirements, the weight is too heavy, the energy density of the battery pack is influenced, and the driving mileage of the vehicle is also influenced. And the corrosion resistance of the metal plate is poor, and the bent part of the metal plate is easy to tear. Cast aluminum battery cases are prone to have defects such as air holes and pinholes due to casting defects. The battery replacement box body made of aluminum alloy materials has the advantages of simple structure, high strength and light weight, and can well solve the technical problems. In order to improve the production efficiency of the battery replacing box body and ensure the production quality of the battery replacing box body, the battery replacing box body is usually produced by a friction stir welding mode at present. But the existing friction welding equipment has higher welding requirements and needs aluminum profiles with good surface quality and flatness; in addition, the friction welding stirring head has large force during welding of the aluminum profile, so that the aluminum profile is easy to warp and deform, and the final welding quality is influenced.
Disclosure of Invention
The invention aims to solve the technical problem of providing an aluminum profile friction welding pinch roller mechanism which can press the front side position of a friction welding stirring head in a follow-up manner, so that the flatness of a welding position is ensured, the aluminum profile is prevented from warping and deforming in the welding process, and the final welding quality is effectively ensured.
The technical scheme adopted by the invention for solving the problems is as follows: the aluminum profile friction welding pinch roller mechanism comprises a connecting disc, wherein a main shaft seat is arranged at the center of the bottom of the connecting disc, a welding main shaft is vertically arranged on the main shaft seat in a penetrating mode, a stirring needle is arranged at the lower end of the welding main shaft, a cylinder seat is arranged on the front side of the main shaft seat, a left support plate and a right support plate are vertically arranged on the cylinder seat, a linear guide rail is arranged on each support plate, a sliding seat is arranged between the left linear guide rail and the right linear guide rail, a pinch roller arm is arranged on the rear side of the sliding seat, and a pinch roller.
Optionally, the rotation direction of the pressing wheel is located in the diameter direction of the connecting disc.
Optionally, an air cylinder is fixedly arranged on the air cylinder seat, the air cylinder is located in front of the sliding seat, a connecting arm is arranged on the front side of the pinch roller arm, and the end of the piston rod of the air cylinder is connected with the connecting arm.
Optionally, the cylinder is located between the left and right linear guide rails.
Optionally, bearing seats are arranged on the left side and the right side of the spindle seat, a transmission shaft penetrates between the left bearing seat and the right bearing seat, and the transmission shaft is used for driving the welding spindle to rotate.
Compared with the prior art, the invention has the advantages that:
the aluminum profile friction welding pinch roller mechanism can press the front side position of a friction welding stirring head in a follow-up manner, so that the flatness of a welding position is ensured, the aluminum profile is prevented from warping and deforming in the welding process, and the final welding quality is effectively ensured.
