Technical Field

[0001] This invention relates to the field of gantry machine tool technology, specifically to a multi-functional testing platform for large gantry carriage assemblies. Background Technology

[0002] The carriage assembly is a key component in gantry CNC machine tools. Existing assembly conditions can only meet partial assembly needs, failing to achieve a complete installation and testing process, especially for multi-functional testing with attachment heads. After the carriage assembly is assembled, precision adjustments and functional debugging are required. These tasks necessitate halting the overall assembly of the gantry machine tool. Precision adjustments to the carriage assembly require rework through machining, leading to repeated disassembly and reassembly risks and waste, resulting in high assembly costs, time delays, and compromised product quality. Therefore, a large-scale gantry carriage assembly multi-functional testing platform is proposed. Summary of the Invention

[0003] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0004] Therefore, the technical solution adopted in this invention is as follows: A multi-functional testing platform for a large gantry carriage assembly includes a frame body. Vibration-resistant adjusting pads are installed at the bottom of the frame body. A ladder is installed inside the frame body, with its top extending above the top of the frame body. A footboard is fixedly installed in the middle of the frame body. Guardrails are installed on the sides of the footboard and the top of the frame body. An upper perforated mounting plate and a lower perforated mounting plate are installed above the footboard on the frame body. An upper transition block and a reference transition block are respectively connected to the upper and lower perforated mounting plates. A carriage assembly is slidably connected to the upper and reference transition blocks. An adjustable motor bracket is installed on the top of the carriage assembly, and a Z-axis servo motor is mounted on the adjustable motor bracket. A gearbox body is installed on the carriage assembly at a position corresponding to the Z-axis servo motor. Oil cooling pipes on the carriage assembly are connected to an oil cooler. A cable chain is connected to the top of the carriage assembly for connecting to an electrical cabinet, and a spindle is mounted in the middle of the carriage assembly.

[0005] Preferably, an accessory head transition plate is fitted at the top of the spindle, one side of which is fixedly installed at the end of the carriage assembly, and the accessory head transition plate is only used to install right-angle heads or five-axis heads.

[0006] Preferably, the width of the upper perforated mounting plate is greater than the width of the lower perforated mounting plate, and the number of the upper transition block and the reference transition block are both two.

[0007] Preferably, the vibration-damping adjusting pad is screwed into the middle with an external hexagonal screw, and the top of the external hexagonal screw passes through the vibration-damping adjusting pad and is threaded to the bottom of the frame body.

[0008] Preferably, the hydraulic lines on the carriage assembly are connected to the hydraulic station, and the hydraulic station and the oil cooler are interconnected.

[0009] Preferably, the vibration-resistant adjusting pads are arranged in five groups of fifteen evenly at the bottom of the frame body.

[0010] Preferably, the maximum Z-axis travel of the carriage assembly is 2.5m.

[0011] Preferably, the output end of the Z-axis servo motor is connected to a Z-axis reducer, the other end of the Z-axis reducer is connected to a coupling, the other end of the coupling is connected to a Z-axis lead screw, both ends of the Z-axis lead screw are provided with bearing assemblies, and a bearing cap, a locking nut and a cap locking screw are provided above the top of the Z-axis lead screw near the bearing assembly to lock the connection between the Z-axis lead screw and the bearing assembly, and a nut seat is connected to the middle of the Z-axis lead screw.

[0013] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows: 1. In this invention, the cooperation between the carriage assembly and the Z-axis servo motor enables the carriage assembly to achieve a Z-axis travel of 2.5m for testing. The large side travel meets various requirements. Furthermore, by utilizing the upper and lower multi-hole mounting plates, along with the upper transition block and reference transition block, different sized structures can be installed. Specifically, based on the multi-hole design of the upper mounting plate and upper transition block, different hole positions can be selected to achieve different installation spacings, thereby installing different upper transition blocks and reference transition blocks to meet different connection sizes. This significantly shortens the overall assembly time, and the modular installation ensures accuracy, allowing for early detection, troubleshooting, and clearing of problems, thus improving the reliability of the device.

[0014] 2. In this invention, by setting up a hydraulic station, oil cooler, and gearbox body, various components can be tested quickly and conveniently. At the same time, the accessory head transition plate can be installed during the operation and accuracy testing of right-angle heads or five-axis heads, thereby ensuring test accuracy, increasing the types of tests that the equipment can perform, and thus meeting different testing needs.
