Description

Technical Field

[0001] This utility model relates to an automated processing equipment, and more particularly to a high-speed punching machine tool. Background Technology

[0002] High-speed punching machines are widely used in the precision processing of materials such as films, flexible circuit boards, and self-adhesive labels. With the development of industrial automation, the requirements for the precision and efficiency of punching processes are becoming increasingly stringent. Traditional punching machine blades typically only achieve simple vertical punching or fixed-path movement, which has the following shortcomings when dealing with workpieces with complex shapes or requiring frequent changes in processing position or angle: 1. Poor flexibility: The tool angle is fixed, and it is impossible to adjust the cutting angle in real time during the machining process, making it difficult to handle complex contours.

[0003] 2. Low positioning efficiency: It relies on the overall moving workpiece stage for positioning, which results in a slow response speed and affects the overall processing efficiency.

[0004] 3. Limited accuracy: Multiple clamping and positioning are required during multi-process machining, resulting in large cumulative errors and making it difficult to guarantee high accuracy.

[0005] Therefore, there is an urgent need for a high-speed punching machine tool that can integrate translation, lifting and rotation movements, and can work with a vision system to achieve automatic positioning and angle correction. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a high-speed punching machine tool with a compact structure, flexible movement, and precise positioning. Its driving device can realize multi-degree-of-freedom coordinated movement, which significantly improves processing capacity and efficiency.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is: a high-speed punching machine tool, including a tool body and a driving device for driving the tool body. The driving device includes a tool clamp for fixing the tool, a rotating mechanism for driving the tool clamp to rotate, a lifting mechanism for driving the rotating mechanism to rise and fall, a first translation mechanism for driving the lifting mechanism to translate along the Y-axis, and a second translation mechanism for driving the first translation mechanism to translate along the X-axis. The driving device cooperates with a vision module. The principle of this utility model is that through the coordinated work of the second translation mechanism (X-axis), the first translation mechanism (Y-axis), the lifting mechanism (Z-axis), and the rotating mechanism, precise positioning and infinite angle adjustment of the tool in three-dimensional space are achieved, greatly enhancing the flexibility of processing. In cooperation with the vision module, automatic identification, positioning, and tracking of workpieces can be achieved, making the punching process fully automated, especially suitable for complex, multi-variety flexible production.

[0008] As an improvement, the second translation mechanism includes a second slide rail, a second slide block that slides with the second slide rail, a second translation motor mounted on the second slide block, a rack parallel to the second slide rail, and a gear meshing with the rack. The second translation motor is connected to the gear, and the bottom of the second slide block is provided with a connecting block that is connected to the first translation mechanism.

[0009] As an improvement, the first translation mechanism includes a first mounting plate, a first slide rail disposed on the first mounting plate, a first slide block that slides with the first slide rail, a first lead screw that threads with the first slide block, and a first translation motor connected to the first lead screw. The connecting block is connected to the first mounting plate, the first slide rail is perpendicular to the second slide rail, and the first translation motor is fixed on the first mounting plate.

[0010] As an improvement, the lifting mechanism includes a hydraulic cylinder, a guide block disposed on the outer wall of the hydraulic cylinder, and a guide rod that slides with the guide block. The piston rod of the hydraulic cylinder is connected to a third mounting plate, the guide rod is connected to the third mounting plate, and the hydraulic cylinder is fixed on a first slide.

[0011] As an improvement, the rotating mechanism includes a first gear pivotally connected to the bottom of the third mounting plate and connected to the tool holder, a second gear meshing with the first gear, a third gear meshing with the second gear, and a rotary motor connected to the third gear, the rotary motor being fixed to the third mounting plate.

[0012] The beneficial effects of this utility model compared with the prior art are: 1. Multi-degree-of-freedom integration: Through the coordinated work of the second translation mechanism (X-axis), the first translation mechanism (Y-axis), the lifting mechanism (Z-axis), and the rotation mechanism, the tool is accurately positioned and infinitely adjustable in three-dimensional space, greatly enhancing the flexibility of machining; 2. High precision and high rigidity: The X and Y axes use motors in conjunction with precision slide rails and transmission components (lead screws / gear racks), while the Z axis uses hydraulic cylinders in conjunction with a guiding mechanism, ensuring high precision, high speed and high rigidity of the motion; 3. High degree of automation: By working with a vision module, it can automatically identify, position and track workpieces, making the punching process fully automated, and is especially suitable for complex, multi-variety flexible production. 4. Compact structure: The various mechanisms are stacked layer by layer and arranged in a reasonable manner. While achieving multiple functions, the overall structure remains compact and is easy to integrate into existing equipment. Attached Figure Description
