Description

Technical Field

[0001] This utility model relates to the technical field of CNC machine tool cutting tools, and in particular to a quick-release tool holder for CNC machine tools. Background Technology

[0002] In today's increasingly industrialized world, CNC machine tools are often used for precise cutting of mechanical workpieces. However, CNC lathes require frequent changes of cutting tools of different specifications. Existing tool fixtures make tool assembly and disassembly time-consuming, labor-intensive, and inefficient. Existing technology publication CN204565659U proposes a clamping fixture for machining square cutting tools. This fixture includes a base with a mounting groove for the square cutting tool. A chuck parallel to the mounting groove is located at one end of the base, and a pressure plate is positioned above the mounting groove. By using a universal chuck to switch between the base and the base of the square cutting tool to be machined, the square cutting tool can be clamped and machined on the CNC machine tool, solving the problem that traditional machine tools can only clamp round cutting tools or require special fixtures for machining square cutting tools. However, its connection method with traditional lathe tool holders is still the existing method, which still requires multiple bolts to clamp and fix the lathe tool during installation. This makes the installation process cumbersome, time-consuming, and labor-intensive, resulting in low installation efficiency. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a quick-release tool holder for CNC machine tools that can quickly load and unload cutting tools, improve loading and unloading efficiency, and simplify the loading and unloading process.

[0004] This utility model discloses a quick-release tool holder for CNC machine tools, comprising a rotating shaft, a tool holder, a cutting tool, a mounting component, a locking component, a quick-release component, and a support assembly. The left end of the tool holder is connected to the rotating shaft, and the left end of the cutting tool is connected to the tool holder via the mounting component. A locking component is installed inside the tool holder, a quick-release component is installed inside the left end of the tool holder, and a support assembly is installed inside the tool holder. The cutting tool is mounted on the tool holder via the mounting component, and the connection is stable through cooperation with the support assembly. After the cutting tool is installed, it can be fixed and locked by the locking component. The quick-release component allows for quick loading and unloading of the cutting tool, greatly improving loading and unloading efficiency and simplifying the loading and unloading process.

[0005] Preferably, the insert component includes a connecting sleeve, a connecting block, and a baffle. The connecting sleeve is installed on the right end of the tool holder, the baffle is installed on the left side of the tool, and the connecting block is installed on the left end of the baffle. During installation, the tool is pushed to insert the connecting block into the connecting sleeve. The baffle can position the tool, increase the support area, and ensure stability during processing.

[0006] Preferably, the locking component includes a locking block, two sets of slide rods, two push plates, two sets of springs, and two locking pins. The locking block is installed on the left side wall of the connecting insert block, and two locking grooves are formed on the locking block. Slide rods are installed on the inner walls of the tool holders at the upper and lower ends of the locking block, and push plates are slidably installed on the slide rods. Locking pins are installed on the inner walls of the push plates at positions corresponding to the locking grooves. Springs are fitted on the outer walls of the slide rods, with one end of the spring connected to the inner wall of the tool holder and the other end connected to the outer wall of the push plate. After the tool is installed, the spring pushes the push plate to slide on the slide rod, and the push plate pushes the locking pins to insert into the locking grooves of the locking block, thereby fixing and locking the tool to prevent it from falling off.

[0007] Preferably, the support component includes two sets of support rods and two support plates. The two sets of support rods are symmetrically installed on the inner walls of the tool holders on the front and rear sides of the locking block. Support plates are installed on the support rods, and the inner walls of the support plates slide in contact with the outer walls of the front and rear ends of the locking block.

[0008] Preferably, the quick-release component includes two wedge blocks, a sliding plate, a trapezoidal block, a return spring, and a pressing assembly. A wedge block is installed on the left side wall of the push plate, the sliding plate is slidably installed inside the tool holder, and a trapezoidal block is installed on the right side wall of the sliding plate. A fixing groove is formed in the middle of the left end of the sliding plate, and the return spring is installed in the fixing groove. The other end of the return spring is connected to the inner left wall of the tool holder. When the tool needs to be removed, the sliding plate moves to the right, causing the trapezoidal block to move to the right, pushing the two wedge blocks, causing the push plate to slide on the slide rod and compress the spring. This causes the locking pin to move out of the locking groove, allowing for quick tool removal and installation, greatly improving loading and unloading efficiency and simplifying the process. The return spring can pull the sliding plate to the left to reset, making it convenient to use.

[0009] Preferably, the pressing assembly includes multiple push rods, a pressing ring, and multiple guide sliders.

The pressing ring is installed on the left side of the push rod. Multiple guide grooves are formed on the outer wall of the rotating shaft, and guide sliders are installed on the inner wall of the pressing ring. The guide sliders slide within the guide grooves. When disassembly is required, pressing the pressing ring pushes the slide plate to the right via the push rods. When the pressing ring moves, it causes the guide sliders to slide within the guide grooves, increasing the structural strength.

[0010] Preferably, it also includes multiple positioning slides and multiple sets of reinforcing blocks. The multiple positioning slides are installed on the outer walls around the connecting plug, and positioning grooves are opened on the inner wall of the connecting sleeve. Multiple sets of reinforcing blocks are installed on the outer wall of the connecting sleeve and the right side wall of the tool holder. When inserting the connecting plug, the positioning slides are driven into the positioning grooves, which can guide and position the plug. At the same time, the reinforcing blocks improve the connection strength and ensure stability.

[0011] Compared with the prior art, the advantages of this utility model are as follows: the cutting tool is installed on the tool holder through the insert component, and the connection is stable by cooperating with the support component. After the cutting tool is installed, it can be fixed and locked by the locking component. The quick-release component can quickly load and unload the cutting tool, which greatly improves the loading and unloading efficiency and simplifies the loading and unloading process.
