Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] The following is combined with Figure 1-10 This application is described in further detail.

[0040] Reference Figure 1-Figure 2 In the first embodiment, a tool head off-machine length detection device comprises a placement table 1, a placement cylinder 3 for placing a tool holder 2, and a measuring plate 4. A tool head 5 is arranged on the tool holder 2, and the tool head 5 faces upward. A mounting seat 6 is fixedly arranged on the placement table 1, and a guide rod 7 is vertically fixedly arranged on the mounting seat 6. A guide hole 8 is provided on the measuring plate 4, and the guide hole 8 is sleeved on the guide rod 7. A distance detector 9 (or a laser displacement measuring instrument) is fixedly arranged on the measuring plate 4. The distance detector 9 in the present embodiment is a distance detector 9 with a display screen, and the detection head of the distance detector 9 faces the placement table 1; a rotating rod 10 is vertically rotatably arranged on the mounting seat 6, and the rotating rod 10 is a screw rod. A connecting hole 11 is provided on the measuring plate 4, and the connecting hole 11 is a screw hole. The rotating rod 10 is threadedly connected to the connecting hole 11, and a hand wheel 12 is fixedly arranged on the rotating rod 10;

[0041] Reference Figure 1-Figure 2When measuring the length of the cutter head 5, the cutter holder 2 is placed in the placement tube 3. At this time, the measuring plate 4 is located above the cutter head 5. The hand wheel 12 is turned to drive the rotating rod 10 to rotate, thereby driving the measuring plate 4 to move downward. When the lower surface of the measuring plate 4 contacts the upper end of the cutter head 5, the hand wheel 12 is stopped. At this time, the distance detector 9 detects the distance from the placement table 1, and after deducting the fixed height such as the corresponding height of the cutter holder 2, the length of the cutter head 5 is obtained. There is no need for manual measurement and comparison, so as to improve the measurement accuracy.

[0042] Reference Figure 3-Figure 10 The difference between the second embodiment and the first embodiment is that: a mounting groove 14 is provided on the measuring plate 4, the mounting groove 14 is a threaded groove, a mounting tube 13 is threadedly connected in the mounting groove 14, a measuring block 15 is inserted in the mounting tube 13, two measuring blocks 15 are provided in the mounting tube 13, a partition 16 is fixedly provided on the mounting tube 13, and the partition 16 is located between the two measuring blocks 15; an anti-slip ring 17 is fixedly provided on the mounting tube 13, the lower side of the measuring block 15 contacts the anti-slip ring 17, and the anti-slip ring 17 blocks the two measuring blocks 15 to prevent the measuring blocks 15 from detaching from the mounting tube 13;

[0043] Reference Figure 3-Figure 10 , a baffle 18 is fixedly arranged on the mounting tube 13, and the baffle 18 is a transparent glass plate. The measuring block 15 is located between the baffle 18 and the anti-slip ring 17. The baffle 18 can prevent the measuring block 15 from being separated from the mounting tube 13. A gap is left between the baffle 18 and the measuring block 15, and a colored marking line 19 is arranged on the measuring block 15; the tips of the cutter head 5 are respectively in contact with the lower surface of the corresponding measuring block 15. When measuring, the two tips of the cutter head 5 are respectively located under the two measuring blocks 15. When the measuring plate 4 descends, the measuring block 15 is in contact with the tip of the cutter. As the measuring plate 4 continues to descend, the tip of the cutter pushes up the measuring block 15 until the upper side of the measuring block 15 is in contact with the baffle 18, and the measuring plate 4 stops moving downward;

[0044] Reference Figure 3-Figure 10 When the height difference between the two measuring blocks 15 is too large, the marking line 19 on the side wall of one of the measuring blocks 15 is exposed to the field of vision. At this time, the staff can judge whether the height difference between the two measuring blocks 15 is too large based on whether the marking line 19 can be observed. If it is too large, the height deviation of the two cutting tips on the surface is too large, and it is necessary to adjust and grind in time to keep the cutting tips consistent and improve the service life of the cutter head 5.
