Description

Technical Field

[0001] This utility model relates to the technical field of cutter head detection, specifically a cutter head external length detection device. Background Technology

[0002] When machining holes in a part, the tool length must be checked and verified first. Only after the tool size is qualified can the part be machined to ensure that the depth of the machined hole is qualified.

[0003] A common way to test the length of a cutting head is for the tester to hold a vernier caliper in one hand and the cutting head in the other, and then measure the length of the cutting head using the vernier caliper.

[0004] Regarding the aforementioned technical conditions, there is also a drawback: measuring the height of the cutter head by hand using a vernier caliper results in inaccurate measurement data due to poor hand-held stability.

[0005] Based on this, in order to improve measurement accuracy, this utility model designs a tool head external length detection device to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting head external length detection device, comprising a placement platform, a placement cylinder for placing a cutting head holder, and a measuring plate. The cutting head is placed on the cutting head holder with the cutting head facing upwards. A mounting base is fixedly installed on the placement platform, and a guide rod is vertically fixedly installed on the mounting base. A guide hole is opened on the measuring plate, and the guide hole is sleeved on the guide rod. The measuring plate is located above the cutting head, and a distance detector is fixedly installed on the measuring plate. The detection head of the distance detector faces the placement platform. When the lower surface of the measuring plate contacts the upper end of the cutting head, the distance detector detects the distance to the placement platform.

[0007] By adopting the above technical solution, when measuring the length of the cutter head, the cutter holder is placed in the placement cylinder, at which point the cutter head is located below the measuring plate. The measuring plate is then placed above the cutter head, with the lower surface of the measuring plate in contact with the cutter head. The distance from the detector is then used to measure the height, thereby obtaining the length of the cutter head. This eliminates the need for manual measurement and comparison, thus improving measurement accuracy.

[0008] Preferably, a rotating rod is vertically rotatably mounted on the mounting base, and a connecting hole is provided on the measuring plate, with the rotating rod threadedly connected to the connecting hole.

[0009] By adopting the above technical solution, the rotating rod rotates, driving the measuring plate to rise and fall. When the measuring plate is placed on the cutter head, it prevents the measuring plate from running away, and at the same time controls the speed at which the measuring plate descends, thus protecting the cutter tip.

[0010] Preferably, the measuring plate is provided with a mounting cylinder, and a measuring block is inserted into the mounting cylinder. Two measuring blocks are provided in the mounting cylinder. An anti-detachment ring is fixedly provided on the mounting cylinder. The lower side of the measuring block is in contact with the anti-detachment ring. A baffle is fixedly provided on the mounting cylinder. The baffle is a transparent glass plate. The measuring block is located between the baffle and the anti-detachment ring. A gap is left between the baffle and the measuring block. A marking line is provided on the measuring block. The tip of the cutting head abuts against the lower surface of the corresponding measuring block. When the height difference between the two measuring blocks is too large, the marking line is exposed in the field of view.

[0011] By adopting the above technical solution, the blade tip is brought into contact with the measuring block for measurement. When the marked line is observed, it indicates that the height deviation of the blade tip is excessive.

[0012] Preferably, a partition is fixedly provided on the mounting cylinder, and the partition is located between the two measuring blocks.

[0013] By adopting the above technical solution, the partition separates the two measuring blocks, reducing the influence between the two measuring blocks.

[0014] Preferably, the measuring plate has a mounting groove, and the mounting cylinder is threaded into the mounting groove.

[0015] By adopting the above technical solution, the mounting cylinder is installed on the measuring plate in a detachable and fixed manner, which facilitates the replacement of mounting cylinders of different specifications.

[0016] Preferably, a mounting ring is fixedly provided on the mounting cylinder, and the mounting ring abuts against the upper surface of the measuring plate.

[0017] By adopting the above technical solution, the mounting ring can prevent the mounting cylinder from excessively entering the mounting groove.

[0018] In summary, this application has the following beneficial technical effects: When measuring the length of the cutter head, the cutter holder is placed in the placement cylinder, at which time the cutter head is located below the measuring plate. The measuring plate is placed above the cutter head, so that the lower surface of the measuring plate contacts the cutter head. At this time, the distance detector detects the height, thereby obtaining the length of the cutter head. There is no need for manual measurement and comparison, thus improving the measurement accuracy. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0034] Reference Figures 1-2 In this embodiment, a tool head height detection device includes a placement platform 1, a placement cylinder 3 for placing a tool holder 2, and a measuring plate 4. The tool head 5 is placed on the tool holder 2 with the tool head 5 facing upward. A mounting base 6 is fixedly installed on the placement platform 1, and a guide rod 7 is vertically fixedly installed on the mounting base 6. A guide hole 8 is opened on the measuring plate 4, and the guide hole 8 is sleeved on the guide rod 7. A distance detector 9 (or laser displacement measuring instrument) is fixedly installed on the measuring plate 4. In this embodiment, the distance detector 9 is a distance detector 9 with a display screen, and the detection head of the distance detector 9 faces the placement platform 1. A rotating rod 10 is vertically rotatably installed on the mounting base 6. The rotating rod 10 is a screw rod. A connecting hole 11 is opened on the measuring plate 4. The connecting hole 11 is a screw hole, and the rotating rod 10 is threadedly connected to the connecting hole 11. A handwheel 12 is fixedly installed on the rotating rod 10.

[0035] Reference Figures 1-2 When measuring the length of the cutter head 5, the cutter holder 2 is placed in the placement cylinder 3, and the measuring plate 4 is located above the cutter head 5. The handwheel 12 is turned, which drives the rotating rod 10 to rotate, thereby moving the measuring plate 4 downward. When the lower surface of the measuring plate 4 contacts the upper end of the cutter head 5, the handwheel 12 is stopped. At this time, the distance detector 9 detects the distance of the placement platform 1. After deducting the fixed height of the corresponding cutter holder 2, the length of the cutter head 5 is obtained. There is no need for manual measurement and comparison, which improves the accuracy of measurement.

[0036] Reference Figures 3-10 The difference between this second embodiment and the first embodiment is that: the measuring plate 4 has a mounting groove 14, which is a threaded groove, and a mounting cylinder 13 is threadedly connected to the mounting groove 14. A measuring block 15 is inserted into the mounting cylinder 13, and there are two measuring blocks 15 in the mounting cylinder 13. A partition 16 is fixedly installed on the mounting cylinder 13, and the partition 16 is located between the two measuring blocks 15. An anti-detachment ring 17 is fixedly installed on the mounting cylinder 13, and the lower side of the measuring block 15 contacts the anti-detachment ring 17. The anti-detachment ring 17 blocks the two measuring blocks 15 to prevent the measuring blocks 15 from detaching from the mounting cylinder 13.

[0037] Reference Figures 3-10A baffle 18 is fixedly installed on the mounting cylinder 13. The baffle 18 is a transparent glass plate. The measuring block 15 is located between the baffle 18 and the anti-detachment ring 17. The baffle 18 can prevent the measuring block 15 from detaching from the mounting cylinder 13. There is a gap between the baffle 18 and the measuring block 15. The measuring block 15 is provided with colored marking lines 19. The blade tip of the cutter head 5 abuts against the lower surface of the corresponding measuring block 15. When measuring, the two blade tips of the cutter head 5 are respectively located below the two measuring blocks 15. When the measuring plate 4 descends, the measuring block 15 abuts against the blade tip. As the measuring plate 4 continues to descend, the blade tip pushes the measuring block 15 upward until the upper side of the measuring block 15 abuts against the baffle 18, at which point the measuring plate 4 stops moving downward.

[0038] Reference Figures 3-10 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 will be 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 blade tips on the surface is too large, and it is necessary to adjust and grind in time to make the blade tips consistent and improve the service life of the blade head 5.

[0039] Reference Figures 3-10 To facilitate the lifting and lowering of the measuring block 15, an appropriate amount of lubricating oil is added to the mounting cylinder 13, which helps the measuring block 15 slide.

[0040] Reference Figures 3-10 The measuring block 15 has a mounting cavity 20, in which a battery 21 is fixedly installed. An indicator light 22 is also fixedly installed in the mounting cavity 20, and a push switch 23 is installed in the mounting cavity 20. The indicator light 22 is electrically connected to the push switch 23, and the push switch 23 is electrically connected to the battery 21. A connecting wire 24 is fixedly installed on the pressing head of the push switch 23. The connecting wires 24 on the two measuring blocks 15 are interconnected. When the height difference between the two measuring blocks 15 is too large, the connecting wire 24 is straightened, the push switch 23 is closed to form a circuit, and the indicator light 22 lights up. When the difference between the two measuring blocks 15 is too large, the connecting wire 24 is straightened, the push switch 23 forms a circuit, and the indicator light 22 lights up, thus further reminding the staff.

[0041] Reference Figures 3-10 The partition 16 separates the two measuring blocks 15, reducing the influence between the two measuring blocks 15; in this embodiment, the partition 16 is a light guide plate. When the indicator light 22 emits light, the light guide plate guides the indicator light 22, making it easier for staff to identify.

[0042] Reference Figures 3-10A counterweight 25 is fixedly installed in the mounting cavity 20. The counterweight 25 can increase the weight of the measuring block 15 and prevent the measuring block 15 from being lifted. The mounting cylinder 13 is threadedly connected in the mounting groove 14, which makes it easy to replace the mounting cylinder 13. In actual use, the mounting cylinder 13 with different numbers of measuring blocks 15 can be replaced according to the number of cutting tips, so as to facilitate the measurement of cutting heads 5 with different numbers of cutting tips.

[0043] Reference Figures 3-10 An installation ring 26 is fixedly provided on the installation cylinder 13. The installation ring 26 abuts against the upper surface of the measuring plate 4. The installation ring 26 can prevent the installation cylinder 13 from excessively entering the installation groove 14.

[0044] Compared with Example 1, Example 2 measures the height while detecting whether the height deviation of the blade tip is too large, thereby reducing the occurrence of chipping and breakage caused by excessive blade tip deviation, and thus improving the service life of the blade head 5.
