Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing, specifically to a servo flexible fixture for an integrated casting of automotive rear floor. Background Technology

[0002] The integrated rear floor casting is a large, thin-walled aluminum part with significant dimensions. Existing technologies typically use specialized fixtures for this purpose. When introducing new products, this requires changing the fixture or using a quick-change device, which is time-consuming and cannot meet the diverse needs of new energy vehicles for integrated rear floor castings. Furthermore, production lines that rely on fixture switching for vehicle model changes suffer from significant accumulation of semi-finished products. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a servo-driven flexible fixture for an integrated casting of automotive rear floor components. This fixture enables seamless switching between multiple products, solving the problem of long changeover times and reducing inventory buildup of semi-finished products during product changeovers.

[0004] The purpose of this utility model is achieved by the following solution: a servo flexible fixture for an integrated casting of an automotive rear floor, comprising a fixture system and a control system, wherein the control system and the fixture system are interconnected. The fixture system includes a fixture base, a high-precision servo module, a positioning mechanism, and a fixture mechanism. The control system includes an integrated module, a PLC control system, an AGV automatic feeding system, a robot, and a servo controller. A linear guide rail is provided on the upper surface of the fixture base, and high-precision servo modules are provided at the four corners of the upper end of the linear guide rail. An integrated module is provided in the center of the fixture base. The fixture mechanism includes two support rods and two clamping clamps. The support rods are located in the center of the left side of the fixture base. The clamping clamps are connected and fixed to the high-precision servo module on the left side and are also connected and fixed to a hydraulic cylinder. The positioning mechanism is connected and fixed to the high-precision servo module on the right side. The high-precision servo module drives the positioning mechanism to position the workpiece.

[0005] The high-precision servo module has a stroke of 200mm.

[0006] The hydraulic cylinder is a hydraulic pneumatic cylinder.

[0007] The high-precision servo module positions the workpiece using an electric cylinder-driven positioning mechanism, which is a combination electric cylinder for the XY and YZ directions.

[0008] The clamping pliers, support rods, and positioning mechanisms are symmetrically arranged on the front and rear sides of the fixture base.

[0009] The advantages of this utility model are: 1. Multi-product shared fixture: The shared fixture production mode eliminates the impact of fixture replacement when switching products.

[0010] 2. Flexible and seamless switching: In conjunction with the whole line scheduling system, it enables efficient and uninterrupted switching between multiple products.

[0011] 3. Stable process support: Provides reliable support for the assembly process of integrated castings under high downward pressure and high torque.

[0012] 4. Solve inventory backlog: The flexible compatibility and seamless integration of multiple models effectively solve the problem of inventory backlog caused by product model changes. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0014] like Figure 1 As shown, a servo-driven flexible fixture for an integrated casting of an automotive rear floor includes a fixture system and a control system, which are interconnected. The fixture system includes a fixture base 1, a high-precision servo module 6, a positioning mechanism 4, and a fixture mechanism 3. The control system includes an integrated module 5, a PLC control system, an AGV automatic feeding system, a robot, and a servo controller. A linear guide rail 2 is provided on the upper surface of the fixture base 1, and high-precision servo modules 6 are installed at the four corners of the upper end of the linear guide rail 2. The stroke of the high-precision servo module 6 is 200mm. The high-precision servo module 6 uses an electric cylinder to drive the positioning mechanism 4 to position the workpiece. The electric cylinder is a combination electric cylinder for the XY and YZ axes. An integrated module 5 is centrally located on the fixture base 1. The fixture mechanism 3 includes two support rods 3-1 and two clamping clamps 3-2. The support rods 3-1 are positioned at the center of the left side of the fixture base 1. The clamping clamps 3-2 are connected and fixed to the high-precision servo module 6 on the left side and to a hydraulic cylinder 3-3, which is a hydraulic cylinder. The positioning mechanism 4 is connected and fixed to the high-precision servo module 6 on the right side. The high-precision servo module 6 drives the two positioning mechanisms 4 to position the workpiece. The clamping clamps 3-2, support rods 3-1, and positioning mechanisms 4 are symmetrically arranged on the front and rear sides of the fixture base 1.

[0015] During workpiece processing, the AGV automatic feeding system transports the material frame carrying the integrated casting of the rear floor to the designated position. The RFID chip on the material frame stores product information. After the production line PLC control system reads the RFID signal, it controls the feeding robot to activate the vision system to photograph and verify the product model, preventing incorrect feeding. After confirmation, the PLC system sends the model signal to the servo controller. The servo controller drives the high-precision servo module, causing the positioning mechanism to move along the linear guide to the preset point of the corresponding model. Then, the cylinder clamping clamps the workpiece for subsequent assembly operations. When switching between multiple products, the high-precision servo module quickly adjusts the positioning, avoiding the time consumption of fixture changes, achieving seamless switching, and reducing the backlog of semi-finished product inventory.
