[0025] The following refers to Figures 1 to 3 to describe the lathe tool detection device according to the embodiments of the present invention.

[0026] The lathe tool detection device according to the embodiments of the present invention includes a magnetic base 100, a mounting part 200, a dial indicator 300, and an extension shaft 400. The magnetic base 100 is used for adsorbing on the tool holder; the mounting part 200 is connected to the magnetic base 100, and a mounting hole 210 is provided on the mounting part 200; the dial indicator 300 is connected to the mounting part 200, and the measuring rod 310 of the dial indicator 300 is arranged in the mounting hole 210; the extension shaft 400 is arranged in the mounting hole 210, and the extension shaft 400 is connected to the measuring rod 310.

[0027] For example Figure 1 and Figure 2 As shown, the magnetic base 100 is used to adsorb on the tool holder of the lathe, so that the lathe tool detection device can be fixed on the lathe. The mounting part 200 is connected to the magnetic base 100. The dial indicator 300 and the extension shaft 400 are both mounted on the mounting part 200. The measuring rod 310 of the dial indicator 300 is connected to the extension shaft 400. By inserting the extension shaft 400 into the gap between adjacent tool holders, the position of the tool can be detected. By observing the reading of the dial indicator 300 and turning the tool holder bolt to make the tool advance or retreat, it can be judged whether the tool position is adjusted in place by visually observing how many threads are adjusted and the change of the reading of the dial indicator 300.

[0028] According to the lathe tool detection device of the present utility model, by such setting, it is not necessary to re-measure the tolerance with the dial indicator 300 after adjusting the tool holder bolt once, but to observe the reading of the dial indicator 300 while adjusting the tool holder bolt to judge whether the tool position is adjusted in place. Moreover, the extension shaft 400 can extend into the gap between adjacent tool holders for detection, and it can adapt to complex planers. After adjusting with the extension shaft 400, the magnetic base 100 only needs to be fixed once for the adjustment of the same pair of tool holders, and the adjustment of the left and right tool holders can be realized, greatly improving the tool adjustment efficiency and thus enhancing the production processing efficiency.

[0029] In some specific embodiments of the present utility model, a separator bushing 510 and a spring 520 are further included. A limit protrusion 410 is provided in the middle of the extension shaft 400. The separator bushing 510 and the spring 520 are sleeved on one end of the extension shaft 400 connected to the measuring rod 310. The separator bushing 510 is fixedly arranged in the mounting hole 210. One end of the spring 520 abuts against the side wall of the separator bushing 510, and the other end abuts against the limit protrusion 410.

[0030] For example Figure 2 As shown, a limit protrusion 410 is provided in the middle of the extension shaft 400. The separator bushing 510 is fixedly arranged in the mounting hole 210. The extension shaft 400 passes through the separator bushing 510 and the spring 520 and is connected to the measuring rod 310 of the dial indicator 300. One end of the spring 520 abuts against the side wall of the separator bushing 510, and the other end abuts against the side wall of the limit protrusion 410. When the extension shaft 400 abuts against the tool to be measured and undergoes displacement, the extension shaft 400 squeezes the measuring rod 310, causing the measuring rod 310 to displace and the dial indicator 300 to display a reading. When the tool to be measured is separated from the extension shaft 400, the elastic force of the spring 520 rebounds the extension shaft 400 back to its original position.

[0031] In some specific embodiments of the present utility model, the mounting hole 210 is a stepped hole. The aperture in the middle of the mounting hole 210 is larger than the aperture at one end of the mounting hole 210 where the extension shaft 400 is arranged. The limiting protrusion 410 is slidably arranged in the middle of the mounting hole 210.

[0032] For example Figure 2 As shown, the mounting hole 210 of the mounting part 200 is a stepped hole with a larger aperture in the middle and smaller apertures at both ends. The limiting protrusion 410 of the extension shaft 400 is adapted to the size of the middle part of the mounting hole 210, so that the limiting protrusion 410 can slide in the mounting hole 210, enabling the extension shaft 400 to move in a specific direction without deviation and stably connect with the measuring rod 310 of the dial indicator 300.

[0033] In some specific embodiments of the present utility model, a contact piece 420 is further included. The contact piece 420 is in a disc shape, and the end face of the contact piece 420 is connected to the extension shaft 400.

[0034] For example Figure 1 , the contact piece 420 is in a disc shape, the end face is connected to the extension shaft 400, and the contact piece 420 is used to abut against the tool. The disc-shaped contact piece 420 has a larger contact area and can contact the tool more fully.

[0035] In some specific embodiments of the present utility model, the contact piece 420 is in a circular disc shape.

[0036] The circular disc-shaped contact piece 420 is easier to process.

[0037] In some specific embodiments of the present utility model, a rotatable support 600 is included. The rotatable support 600 is rotatably connected to the magnetic base 100 and can rotate relative to the magnetic base 100. The mounting part 200 is connected to the rotatable support 600.

[0038] For example Figure 1 and Figure 2 As shown, the rotatable support 600 is rotatably connected to the magnetic base 100, enabling the dial indicator 300, the mounting part 200, and the extension shaft 400 to rotate to a certain extent, so that the extension shaft 400 can be rotated and placed into the gap between the tool holders.

[0039] In some specific embodiments of the present utility model, the rotatable support 600 is made of aluminum.

[0040] The rotatable support 600 is made of aluminum, so that the rotatable support 600 will not be attracted by the magnetic base 100. The magnetic base 100 is firmly fixed to the tool holder by magnetism, and the aluminum rotatable support 600 can easily rotate relative to the magnetic base 100.

[0041] In some specific embodiments of the present utility model, a fixing nut 220 is further included. The fixing nut 220 is fixedly connected to the mounting portion 200, and the dial indicator 300 is fixedly connected to the mounting portion 200 through the fixing nut 220.

[0042] For example Figure 1 and Figure 2 As shown, the fixing nut 220 is fixedly connected to the mounting portion 200, and the dial indicator 300 is fixedly connected to the mounting portion 200 through the fixing nut 220, which can ensure the stability of the installation by 100%.

[0043] In some specific embodiments of the present utility model, an embedding hole 430 is formed at one end of the extension shaft 400 connected to the measuring rod 310, and the measuring rod 310 is embedded in the embedding hole 430 to be connected to the extension shaft 400.

[0044] For example Figure 3 As shown, an embedding hole 430 is formed at one end of the extension shaft 400 connected to the measuring rod 310, and the measuring rod 310 of the dial indicator 300 is embedded in the embedding hole 430 to be connected to the extension shaft 400, which can ensure the stability of the connection.
