[0002] A numerically controlled machine tool is an automated machine tool equipped with a program control system. This control system can logically process a program with control codes or other symbolic instructions, decode it, represent it in coded numbers, and send various control signals from the numerical control device to control the actions of the machine tool to automatically machine parts. Numerically controlled machine tools have better solved the problems of machining complex, precise, small-batch, and multi-variety parts, and are a flexible and high-performance automated machine tool.

[0003] During the use of a numerically controlled machine tool, it mainly relies on various tools to machine parts. However, in the actual use of the internal machining equipment of a numerically controlled machine tool, there is a problem that the tool shank cannot be disassembled, and the tool can only be replaced in the machine. After the tool is replaced, the tool length cannot be effectively measured. The traditional measurement method is to use a vernier caliper or a depth gauge for measurement. However, due to different tool structures and clamping methods, the tool length cannot be accurately measured, which is not conducive to subsequent machining. Therefore, improvements are needed. Content of the Utility Model

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figures 1 to 7 shown, the present invention provides a manual in-machine measuring device for the tool length of a numerical control machine tool, including a measuring column 1. A measuring slider 2 is movably sleeved in the middle of the outer surface of the measuring column 1. A measuring base 3 is movably sleeved at the bottom end of the measuring column 1. A fixed slot 6 is opened inside the measuring column 1. A measuring fixed grating 4 is fixedly sleeved on the inner surface of the fixed slot 6. The bottom end of the measuring fixed grating 4 is movably connected to the top end of the measuring base 3. A digital display instrument 5 is fixedly installed at the front end of the measuring slider 2. The rear side of the outer surface of the digital display instrument 5 is movably connected to the front side of the outer surface of the measuring column 1. The rear side of the outer surface of the digital display instrument 5 is movably connected to the front side of the outer surface of the measuring fixed grating 4.

[0024] When using the measuring device, the measuring device can be fixed at the gap between the spindle tool holder and the spindle end face of the numerical control machine tool through the measuring base 3. Subsequently, when the digital display instrument 5 is pushed, the digital display instrument 5 will drive the measuring slider 2 to move along the outer surface of the measuring column 1, so that the measuring slider 2 contacts the outer end of the tool. Also, because scale lines are evenly arranged on the outer side of the measuring fixed grating 4 facing the outside, the digital display instrument 5 cooperating with the measuring fixed grating 4 can realize the manual in-machine measurement of the tool length of the numerical control machine tool, thereby improving the convenience of using the measuring device and the accuracy of measurement.

[0025] Among them, a step through hole 8 is opened at the top of the front end of the measuring base 3. A bolt 9 is movably sleeved at the rear side inside the step through hole 8; the front side inside the step through hole 8 has the same size as the measuring column 1, so as to enhance the connection stability between the measuring column 1 and the measuring base 3.

[0026] Among them, a threaded hole 7 is opened at the bottom end of the measuring column 1. The inner surface of the threaded hole 7 is threadedly sleeved with the outer surface of the bolt 9. A waist-shaped card slot 10 is opened at the bottom of the measuring base 3; the threaded hole 7 is aligned with the circular through hole at the rear side inside the step through hole 8, so as to facilitate the bolt 9 to enter the threaded hole 7. The existence of the waist-shaped card slot 10 can facilitate the measuring base 3 to be inserted into the gap between the spindle tool holder and the spindle end face of the numerical control machine tool.

[0027] Wherein, a convex rod is provided at the bottom on the right side of the outer surface of the measuring slider 2, facing the waist-shaped card slot 10; due to the arrangement of the convex rod on the outer surface of the measuring slider 2, it will be convenient for the measuring slider 2 to abut against the outer end of the tool, so as to facilitate the measurement of the tool length.

[0028] Wherein, a protrusion is provided at the bottom on the left side of the outer surface of the digital display 5, away from the waist-shaped card slot 10; due to the arrangement of the protrusion on the outer surface of the digital display 5, it will provide convenience when the operator pushes the digital display 5.

[0029] Wherein, both the inner surface of the measuring slider 2 and the outer surface of the measuring column 1 are smooth, and the width inside the measuring slider 2 is the same as the width outside the measuring column 1; the smooth design of the inner surface of the measuring slider 2 and the outer surface of the measuring column 1 can ensure the stability of the movement of the measuring slider 2 along the outer surface of the measuring column 1.

[0030] Wherein, a digital display module is provided inside the digital display 5, and an electronic display screen is provided on the outer surface of the digital display 5; by the cooperation of the digital display module inside the digital display 5 and the scale lines on the outer surface of the measuring fixed grating 4, the reading of the tool length can be displayed on the electronic display screen on the outer surface of the digital display 5.

[0031] The working principle and usage process of the present utility model:

[0032] First, the operator aligns the waist-shaped card slot 10 of the measuring device with the gap between the machine tool spindle tool holder and the spindle end face. Then the operator pushes the measuring slider 2, so that the measuring slider 2 drives the digital display 5 to move along the outer surface of the measuring column 1 until the measuring slider 2 moves to the end far from the measuring base 3. Subsequently, the operator inserts the measuring base 3 into the gap between the machine tool spindle tool holder and the spindle end face through the waist-shaped card slot 10. At this time, the measuring device will be fixed. Then, the operator pushes the protrusion on the outside of the digital display 5, so that the digital display 5 drives the measuring slider 2 to move along the outer surface of the measuring column 1 until the stop rod on the side of the measuring slider 2 facing the waist-shaped card slot 10 aligns with the outer end of the tool. At this time, in cooperation with the measuring fixed grating 4, the digital display module inside the digital display 5 will display the length reading of the tool on the electronic display screen of the digital display 5. In this way, the manual in-machine measurement of the tool length of the CNC machine tool can be completed, thereby improving the accuracy and convenience of measuring tools with different structures and different clamping methods.
