[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 5 As shown, a body roll molding die mounting and positioning device includes a tooling table 10, a clamping mechanism 11 arranged around the tooling table 10, and a positioning mechanism 12 arranged on the upper surface of the tooling table.

[0023] The clamping mechanism 11 uses a positioning cylinder 111 as its power source to provide Z-axis clamping force to clamp the car body hemming mold onto the tooling table 10.

[0024] Reference Figure 1 as well as Figure 2As shown, there are five clamping mechanisms 11, which are respectively arranged along both ends and the middle of the body rolling die. A positioning block 112 is installed at the bottom of the output end of the positioning cylinder 111, and a positioning support block 113 is fixedly connected to the bottom of the positioning block 112.

[0025] This mechanism breaks away from the traditional embedded and inset bolt positioning structure. Embedded and inset bolt structures can loosen during production due to prolonged reciprocating motion; under repeated loading and unloading, bolts may also experience fatigue fracture after a certain number of cycles. Disassembling bolts after a malfunction is extremely difficult, time-consuming, and requires limited space; simultaneously, the bolt's torque capacity is unstable, and excessive force or failure to adhere to the specified torque value during tightening can lead to bolt deformation or breakage. The newly adopted hemming die positioning mechanism breaks with the traditional bolt positioning principle, employing a clamping mechanism 11 and precise die positioning. During operation, the positioning clamping mechanism 11, when the push rod in the clamping cylinder 111 extends, the air pressure acts on the piston rod inside the cylinder, causing the piston rod to reciprocate. When the air pressure of the clamping cylinder 111 acts on the piston rod, the positioning block 112 on the piston and the positioning support block 113 at the front end generate clamping force when the piston moves outward. The clamping mechanism 11 applies Z pressure to the positioning mold to complete the positioning and clamping process.

[0026] The positioning mechanism 12 includes a number of positioning rollers 121 arranged in a central ring. The positioning rollers 121 enclose a positioning space for the positioning pins on the body rolling die to be inserted, and are used to provide XY-direction limits.

[0027] Reference Figures 3 to 5 As shown, two positioning mechanisms 12 are provided, located at both ends of the body rolling die. Each positioning mechanism 12 includes a positioning platform 122, with a positioning hole 123 at its center for inserting a positioning pin. Positioning rollers 121 are arranged around the positioning hole. A vertical support frame is provided around the circumference of the positioning platform 122, and the positioning rollers 121 are rotatably connected to the support frame. When the positioning pin is inserted into the positioning hole 123, the circumferential surface of the positioning rollers 121 contacts the circumferential surface of the positioning pin. A total of four positioning rollers 121 are provided.

[0028] The positioning mechanism 12, employing rollers, ensures the roller guides maintain the correct position of the positioning pins, reducing wear, minimizing frictional heat, minimizing thermal deformation, and providing stability and precision. Its structural design can withstand large radial and axial loads, and simplifies installation and disassembly, facilitating maintenance and replacement. This structure perfectly meets the high-precision requirements of on-site processes, ensuring high accuracy and stability through precise positioning. In the event of mold wear or malfunction, the positioning pins assist in workpiece alignment and positioning during assembly and disassembly, simplifying the assembly process, improving work efficiency, and ensuring correct alignment of components for easier disassembly and maintenance.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
