Description
Technical Field
[0001] The present application relates to the technical field of numerically controlled machine tools, and in particular to a numerically controlled machining mechanism with a pop-up flying disc tool magazine function. Background Art
[0002] CNC machine tool is the abbreviation of digital control machine tool, which is an automated machine tool equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions, decode them, express them in coded numbers, and input them into the CNC device through information carriers. After calculation and processing, the CNC device sends various control signals to control the movement of the machine tool and automatically process the parts according to the shape and size required by the drawing.
[0003] CNC machine tools process parts through tools installed on the spindle. Traditional CNC machine tools usually require workers to manually change tools. During the tool change process, the CNC machine tool needs to stop working. After the workers complete the manual tool change operation, they can process the parts. However, the manual tool change operation has a low degree of automation, which reduces the working efficiency of CNC machine tools.
[0004] With continuous innovation, most of the current CNC machine tools are equipped with a tool magazine, which allows the CNC machine tools to perform automatic tool change operations. Specifically, the CNC machine tool is installed with a tool magazine with multiple tools placed on it. When the tool change operation is required, the spindle moves to the tool change position of the tool magazine under the control of the PLC control system for automatic tool change operation, which is simple and convenient.
[0005] With regard to the above-mentioned related technologies, the inventor believes that when a tool changing operation is required, the spindle needs to first move to the tool changing position of the tool magazine to perform the tool changing operation. After the tool changing operation is completed, the spindle moves to the processing position to perform processing operations on the parts. This movement process not only reduces work efficiency, but also the tool magazine needs to be installed at a position outside the processing position of the CNC machine tool, which undoubtedly increases the occupied space of the CNC machine tool. This problem urgently needs to be improved. Utility Model Content

[0034] The following is combined with Figure 1-4 This application is described in further detail.
[0035] The embodiment of the present application discloses a CNC machining mechanism with a ejection disc tool magazine function, referring to Figure 1 , including a spindle box 1, the bottom of which is connected to a tool, and the spindle box 1 is controlled by a CNC machine tool to move vertically up and down. A tool changing mechanism 2 is provided on one side of the spindle box 1, and the tool changing mechanism 2 performs automatic tool changing operations. Specifically, the tool changing mechanism 2 includes a tool magazine 21, and the tool magazine 21 is located on one side of the spindle box 1 and is turned upside down. The lower end of the tool magazine 21 abuts and slides on the spindle box 1. The tool magazine 21 is arranged in a flying saucer shape, and a plurality of accommodating grooves 5 for accommodating tools are evenly spaced at the edge of the tool magazine 21. The tool magazine 21 stores a plurality of tools through the plurality of accommodating grooves 5. It should be noted that the diameter of the tool magazine 21 is greater than the width of the spindle box 1, so that the tool magazine 21 can store more tools. Refer to Figure 2 and Figure 3 The tool magazine 21 has a tool changing point 3 and a storage point 4. The tool changing point 3 is opposite to the tool in the vertical direction, and the storage point 4 is located on one side of the tool. The tool magazine 21 switches between the tool changing point 3 and the storage point 4 by flipping up and down. When the spindle box 1 drives the tool to move vertically upward, the tool rises and leaves the processing position, and the tool magazine 21 flips downward to the tool changing point 3 to perform the tool changing operation. When the spindle box 1 drives the tool to move vertically downward, the tool descends and enters the processing position, and the tool magazine 21 flips upward to the storage point 4 to perform the tool processing operation.
[0036] Reference Figure 1 The tool changing mechanism 2 further includes a tool magazine guide plate 22, which is used to guide the up and down flipping operation of the tool magazine 21. Specifically, the tool magazine guide plate 22 is vertically fixed to the side wall of the spindle box 1, and the lower end of the tool magazine 21 abuts and slides on the side wall of the tool magazine guide plate 22 away from the spindle box 1. Figure 4 The tool magazine guide plate 22 includes a processing portion 221 located at the upper end and a tool changing portion 222 located at the lower end, and the width of the processing portion 221 is greater than the width of the tool changing portion 222. Figure 3 When the lower end of the tool magazine 21 abuts against the processing portion 221, since the width of the processing portion 221 is greater than the width of the tool changing portion 222, the processing portion 221 lifts the lower end of the tool magazine 21, thereby realizing the upward flipping of the tool magazine 21, so as to facilitate the tool processing operation; Figure 2When the lower end of the tool magazine 21 abuts against the tool changing part 222, since the width of the tool changing part 222 is smaller than the width of the processing part 221, the lower end of the tool magazine 21 falls downward, thereby realizing the downward flipping of the tool magazine 21, so that the tool can be changed on the tool magazine 21. The specific action is as follows: when the lower end of the tool magazine 21 abuts against the tool changing part 222, the spindle box 1 drives the tool magazine guide plate 22 to move vertically downward along the Z axis, the spindle box 1 automatically releases the tool, and the tool is automatically installed in the tool magazine 1 at the tool changing point 3 The tool magazine 21 is placed in the receiving groove 5, and then the spindle box 1 drives the tool magazine guide plate 22 to make a vertical upward movement of the Z axis, so that the tool magazine 1 can rotate along its axis to the position where the tool to be replaced is located at the tool changing point 3, and then the spindle box 1 drives the tool magazine guide plate 22 to make a vertical downward movement of the Z axis again, and the tool located at the tool changing point 3 is separated from the tool magazine 21, and the spindle box 1 automatically grabs the tool to complete the automatic tool changing operation, and finally the spindle box 1 continues to make a vertical downward movement of the Z axis to reach the processing position of the new tool for processing.
[0037] Reference Figure 4 The tool magazine guide plate 22 also includes a transition portion 223 located in the middle, and the transition portion 223 is arranged in an arc shape. The transition portion 223 is arranged in an arc shape to facilitate the mutual sliding conversion of the lower end of the tool magazine 21 between the processing portion 221 and the tool changing portion 222, so as to improve the smoothness and stability of the tool magazine 21 when turning over.
[0038] Reference Figure 1 The tool changing mechanism 2 also includes a spring 23, one end of the spring 23 is fixedly connected to the side wall of the spindle box 1, and the other end of the spring 23 is fixedly connected to the tool magazine 21, and the spring 23 is always in a tensioned state, so that the tool magazine 21 is always close to the side wall of the spindle box 1, so as to improve the stability of the tool magazine 21 and the stability during the tool changing operation.
[0039] Reference Figure 1 The number of spindle boxes 11 of a CNC machine tool is set to be multiple. In the present embodiment, the number of spindle boxes 1 is set to three. The three spindle boxes 1 are arranged side by side and spaced apart along the X-axis direction of the CNC machine tool, and each spindle box 1 is provided with a tool magazine 21, so that automatic tool changing operation can be performed within the range of each spindle box 1.
[0040] Since the tool magazine 21 is large in size and space needs to be left between adjacent spindle boxes 1 for the tool to move on the X-axis, the space occupied by the CNC machine tool is large. In this embodiment, the two tool magazines 21 located on both sides are inclined in the horizontal direction relative to the tool magazine 21 located in the middle position to reduce the space occupied by the CNC machine tool.
[0041] The implementation principle of a CNC machining mechanism with a pop-up flying disc tool magazine function in an embodiment of the present application is as follows: when a tool changing operation is required, the spindle box 1 drives the tool magazine guide plate 22 to move vertically upward, and at the same time, the lower end of the tool magazine 21 slides to the tool changing part 222 with a smaller width, so that the tool magazine 21 flips downward to the tool changing point 3. At this time, the tool can perform a tool changing operation at the tool changing point 3. When a machining operation is required, the spindle box 1 drives the tool magazine guide plate 22 to move vertically downward, and at the same time, the lower end of the tool magazine 21 slides to the processing part 221 with a larger width. The processing part 221 lifts the lower end of the tool magazine 21 to flip the tool magazine 21 upward to the storage point 4. At this time, the tool can perform a machining operation to avoid the tool magazine 21 interfering with the machining operation of the tool. The tool magazine 21 is located on one side of the spindle box 1, which is convenient for the tool to perform a tool changing operation during the vertical up and down movement of the tool, saving the time of the tool changing operation, and the tool changing operation is simple and convenient, which improves the working efficiency of the CNC machine tool and helps to reduce the occupied space of the CNC machine tool.
[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
