[0002] CNC machining is a high-precision and high-efficiency production method, which is widely used in the aviation industry, the electronics industry and the machinery manufacturing industry. CNC machine tools are automated machine tools equipped with a program control system, which can logically process programs with control codes or other instructions and compile them, so that auxiliary actions such as machine start and stop, workpiece clamping, tool replacement, coolant switch, etc. can be completed and parts can be processed.

[0046] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0047] See also Figures 1 to 4 The embodiment of the present application provides a special machine tool tool length detection device, comprising:

[0048] Base 1, support 2, column 3, measuring structure 4 and rotating seat structure 5;

[0049] The base 1 is arranged at the bottom of the column 3, and the rotating seat structure 5 is arranged at the top of the column 3. The base 1 is used to carry the entire detection device;

[0050] One end of the support 2 is connected to the rotating seat structure 5, and the other end is connected to the measuring structure 4. The support 2 is used to fix the connection between the rotating seat structure 5 and the measuring structure 4. The measuring structure 4 is used to accommodate the tool to be tested. The rotating seat structure 5 is used to calibrate the length parameter of the tool to be tested and fix the tool.

[0051] When a tool to be inspected is placed on the measuring structure 4 , the measuring structure 4 is used to inspect the length of the tool.

[0052] The embodiment of the present application provides a device having a base 1, a support 2, a column 3, a measuring structure 4 and a rotating seat structure 5. The tool to be detected can be placed on the measuring structure 4, and the measuring structure 4 can detect its length. During the detection process, the original data of the tool detection is corrected by the rotating seat structure 5, and the tool is fixed after the correction is completed, thereby realizing the automation of the entire tool detection process. Compared with manual measurement, the measurement accuracy of measuring the fit between the tool and the special machine tool is improved by mechanical measurement.

[0053] In practical applications, the rotating seat structure 5 includes a rotating seat 21, a pressure plate 22, a butterfly spring 23 and a handle 24. The pressure plate 22 is arranged on the top of the rotating seat 21. A groove is arranged in the middle of the pressure plate 22 to accommodate the butterfly spring 23. The butterfly spring 23 is connected to the handle 24 through a pin 25. The function of the handle 24 is to apply an external force to the pressure plate 22, so that the butterfly spring 23 is deformed, and then the deformation of the butterfly spring 23 generates pressure. When the handle 24 presses the pressure plate 22, the butterfly spring 23 also presses the rotating seat 21 to prevent the rotating seat 21 from moving axially.

[0054] Optionally, the detection device further includes a gasket 26 , which is disposed between the pressure plate 22 and the handle 24 , and through which the pin 25 passes. The gasket 26 is used to protect the surface of the pressure plate 22 and disperse the pressure of the handle 24 on the pressure plate 22 .

[0055] Optionally, the detection device also includes a sleeve 27, which is fitted between the rotating seat 21 and the column 3 and can be used to reduce the friction generated between the rotating seat 21 and the column 3 during the measurement process, so that the rotating seat 21 can rotate smoothly, wherein the sleeve 27 adopts an H7 / n6 interference fit with the rotating seat 21 and an H8 / f7 clearance fit with the column 3.

[0056] Optionally, the detection device further includes a spring washer 28 , which is built into the center of the base 2 and passes through the column 3 ; the spring washer 28 is used to increase the friction between the base 2 and the column 3 , so that the base 2 and the column 3 are tightly connected.

[0057] In actual application, the measuring structure 4 includes a screw sleeve 31, a positioning sleeve 32, a side rod 33, a clamping nut 34, an adjusting nut 35 and an extension shaft 36; the screw sleeve 31 and the support 2 can be connected by welding, the screw sleeve 31 is a hollow ring, the side rod 33 is inserted into the screw sleeve 31 by passing through the ring, and the extension shaft 36 is connected to the bottom of the side rod 33 near the base 1, and the tool to be tested can be placed on the extension shaft 36; the adjusting nut 35 is arranged on the extension shaft 36, and is used to adjust the length that the extension shaft 36 can extend; the clamping nut 34 is arranged on the screw sleeve 31, and this clamping nut 34 is used to fix the tool whose length has been tested for secondary fixation; the base 2 and the measuring structure 4 can be fixedly connected by screws.

[0058] Optionally, the measuring structure 4 also includes a limit pin 37, which is arranged on the screw sleeve 31. The limit pin 37 is used to control the side rod 33 to move up and down within a preset range. In addition, it can also prevent the side rod 33 from escaping from the screw sleeve 31, thereby protecting the side rod 33.

[0059] Specifically, the tool length of a special machine tool is a set length. Therefore, before the machine tool works, it is necessary to first check whether the tool length of the special machine tool matches the machine tool. If not, the tool length needs to be adjusted to match the machine tool. The matching process is as follows: after placing the tool whose length needs to be detected on the extension shaft 36, check whether the top of the side rod 33 and the top of the screw sleeve 31 are flush. If they are flush, it can be determined that the detection tool has reached a length that matches the machine tool and no adjustment is required. If they are not flush, it can be determined that the detection tool has not yet reached a length that matches the machine tool and it is necessary to adjust the tool length by adjusting the adjusting nut 35 on the extension shaft 36. Within the preset range controlled by the limit pin 37, if the tool length can be adjusted until the top of the side rod 33 is flush with the top of the screw sleeve 31, it proves that the measurement accuracy of the fit between the detection tool and the special machine tool is high. If the tool length still cannot be adjusted to the top of the side rod 33 being flush with the top of the screw sleeve 31 when the critical value of the axial movement of the side rod 33 controlled by the limit pin 37 has been reached, it proves that the measurement accuracy of the fit between the detection tool and the special machine tool is low and the tool needs to be replaced.

[0060] Optionally, in the present detection device, there are at least two measurement structures 4 .
