Description

Technical Field

[0001] The utility model relates to the technical field of boring machine devices, and more specifically, the utility model relates to a numerical control boring machine capable of quickly changing tools. Background Technique

[0002] A numerical control boring machine is a device used for machining the surface precision of workpieces, and is commonly used for machining holes. The boring machine has good machining precision for workpieces. Nowadays, numerical control boring machines are widely used in major factories. The numerical control machine tools can be set with various working programs. When a button is pressed or a program is executed, each mechanical component can complete the work tasks in sequence according to the set order. The traditional numerical control boring machine is composed of a rotating shaft, a boring machine body, corresponding driving equipment, a boring tool, etc. The boring tool is composed of a tool holder, a tool head and a tool bar. During work, the workpiece is machined by relying on a guide bar. When replacing the tool bar, it is necessary to rotate the internal hexagonal bolt for fixing on the tool head to disassemble and assemble the tool bar. Although such traditional devices can achieve automatic precision machining tasks, when replacing the tool bar, an internal hexagonal tool is required to disassemble the tool bar, and the whole process takes a certain amount of time, which to a certain extent affects the work efficiency and brings inconvenience to users. In order to solve the deficiencies of the prior art, we propose a numerical control boring machine capable of quickly changing tools. Content of the Utility Model

[0005] The installation component includes a tool holder and a tool head. The tool holder is detachably installed on the inner wall of the rotating shaft. The tool head is fixedly installed on the outer surface of one side of the tool holder. A tool bar is detachably installed on the inner wall of the tool head. A spring is fixedly connected to the inner wall of the tool head. One end of the spring is fixedly connected to a clamping block. The clamping block is slidably connected to the inner wall of the tool head. A limiting groove is opened on the outer wall of the tool bar. A trapezoidal groove is opened on the inner wall of the clamping block. A self-locking button switch is arranged on the tool head. A clamping rod is slidably connected to the inner wall of the tool head. By pressing the self-locking button switch, the clamping rod is stuck in the trapezoidal groove and locked. By pressing the self-locking button switch again, the clamping rod is unlocked and withdrawn from the trapezoidal groove.

[0006] One end of the clamping block is arc-shaped, and the arc-shaped section of the clamping block is located in the limiting groove. The other end of the clamping block is square, and the square section of the clamping block is located outside the limiting groove. When the button of the self-locking button switch is pressed, one end of the locking rod can be inserted into the inside of the clamping block along the hypotenuse of the trapezoidal groove, aiming to push the square section of the clamping block into the inside of the limiting groove and fix the tool rod on the inner wall of the tool head.

[0007] Among them, there are two groups of the springs, clamping blocks and limiting grooves, which are located on both sides of the outer wall of the tool rod, aiming to fix the tool rod.

[0008] Among them, the switching component includes an electric slide rail, which is fixedly installed on the upper outer surface. A slider is slidably connected to the inner wall of the electric slide rail. A rotating shaft is rotatably connected to the upper inner wall of the slider.

One end of the rotating shaft is fixedly connected with a gear. An electric push rod II is fixedly installed on the upper outer surface of the slider. A rack is fixedly connected to the outer wall of the push rod of the electric push rod II. The gear and the rack are meshed. A spare rack is fixedly installed on the upper outer surface of the boring machine body on one side of the electric slide rail. An electric push rod III is fixedly installed in the inner wall of the rotating shaft. An installation groove is opened on the outer wall of the tool handle. The push rod of the electric push rod III is slidably connected to the outer wall of the installation groove.

[0009] Among them, a notch is opened on the outer wall of the tool handle so that the electric gripper can clamp the tool handle. The electric gripper, the electric slide rail, the electric push rod I, the electric gripper, the electric push rod II and the electric push rod III are electrically connected to the control box, aiming to complete the work of quickly switching the boring tool according to the set order through program control.

[0012] Through the installation component of the utility model, including the tool handle, when disassembling the tool rod, when the button of the self-locking button switch is pressed, the button drives the square section of the clamping block to withdraw from the inside of the limiting groove, and the tool rod is directly pulled out. At this time, the arc-shaped section of the clamping block is located in the limiting groove, and the tool rod pushes the clamping block away and is smoothly pulled out. When installing the tool rod, the tool rod is directly inserted into the inner wall of the tool head. The tool rod pushes the clamping block away, and then the arc-shaped section of the clamping block is located in the limiting groove. The button of the self-locking button switch is pressed again to push the square section of the clamping block into the inside of the limiting groove. At this time, the clamping block clamps the tool rod, and the tool rod will be fixed. With the above structure, when the button of the self-locking button switch is pressed, the locking and unlocking of the tool rod are realized, the time for replacing the tool rod is saved, the work efficiency is improved, it is convenient for the user to quickly disassemble the tool rod, and the flexibility of the device is improved;

[0013] The utility model realizes the switching of the boring tool through a switching component, including an electric slide rail. When the whole boring tool needs to be replaced, the operation control box is used to extend the electric gripper to grab the boring tool. When the push rod of the third electric push rod retracts, the tool holder is no longer fixed to the inner wall of the rotating shaft, and the electric gripper can grab the boring tool and pull it out. The electric gripper can be driven by the second electric push rod to rotate, and the electric slide rail drives the electric gripper to move. The boring tool is grabbed and placed on the spare rack, and the spare boring tool is grabbed and installed on the inner wall of the rotating shaft. With the above structure, by operating components such as the electric gripper through the control box, the switching work of the boring tool is realized, the operation steps are reduced, the time for switching the boring tool is saved, it is convenient for the user to quickly switch the boring tool, and the practicability of the device is improved.

Since the spring 34 is fixedly connected to the inner wall of the tool bit 32, and one end of the spring 34 is fixedly connected to the latch 35. At this time, the arc section of the latch 35 is located in the limit groove 36, and the tool shank 33 pushes the latch 35 away and is smoothly pulled out. When installing the tool shank 33, directly insert the tool shank 33 into the inner wall of the tool bit 32. The tool shank 33 pushes the latch 35 away. Then, the arc section of the latch 35 is located in the limit groove 36.
