Technical Field
[0001] This utility model relates to the field of marking technology for toothed hobbing drill bits, and in particular to a marking fixture for toothed hobbing drill bits. Background Technology
[0002] Toothed hobbing cutters are rock-breaking tools widely used in mining, tunneling, oil and gas exploration, and other fields. They break rocks by embedding carbide teeth into the cutter body to improve the rock-breaking efficiency and service life of the drill bit. In the manufacturing process of toothed hobbing cutters, the marking process is crucial. It not only helps with product quality traceability and batch management, but also provides key information for subsequent use and maintenance.
[0003] In the existing technology, some marking fixtures adopt manual marking methods, which are inefficient and difficult to guarantee the accuracy and consistency of marking. They are prone to problems such as blurry markings and positional deviations, and the marking positions are limited. Therefore, we propose a marking fixture for toothed hobbing drill bits.

[0022] The adjusting plate 1 serves as the main support structure of the tooling. A rotation adjustment assembly and a movement limiting assembly are installed on top of the adjusting plate 1 to fix and adjust the position of the toothed hob drill bit blank 3. An angle flipping drive assembly is installed on the lower side of the adjusting plate 1 to achieve multi-angle adjustment of the tooling. A movable spraying assembly is located on one side of the adjusting plate 1 for automated marking of the drill bit blank.
[0023] The rotation adjustment assembly includes a side plate 4, a support base 5, a motor 6, a gear 7, a gear 8, and a three-jaw chuck 9. The side plate 4 is vertically fixed to one side of the adjustment plate 1, and the support base 5 is fixed to the outside of the side plate 4 for mounting the motor 6. The output shaft end of the motor 6 is connected to the gear 7, and the gear 7 meshes with the gear 8. The other side of the gear 8 is fixedly connected to the three-jaw chuck 9.
[0024] Working principle: Start motor 6, which drives the three-jaw chuck 9 to rotate through gear 7 and gear 8, thereby causing the toothed hob cutter blank 3 to rotate around its axis, making it easy to mark different positions on the cutter blank.
[0025] The movable limiting assembly includes a slide 10, a slide plate 11, a turntable 12, a second motor 13, and a threaded rod 14. The slide 10 is horizontally arranged on one side of the adjusting plate 1. The slide plate 11 is slidably connected to the slide 10. One side of the slide plate 11 is rotatably connected to the turntable 12 through a bearing. The second motor 13 is fixed to one side of the adjusting plate 1, and its output shaft end is connected to the threaded rod 14. The threaded rod 14 passes through the slide plate 11 and is threadedly engaged with it.
[0026] Working principle: Start motor 13 to drive threaded rod 14 to rotate, which in turn drives slide plate 11 to move horizontally along slide groove 10, thereby adjusting the position of turntable 12 and toothed hob drill bit blank 3, and achieving precise positioning of drill bit blank.
[0027] The angle-flipping drive assembly includes a connecting plate 15, an I-beam support plate 16, a battery 17, a third motor 18, a third gear 19, and a semi-circular gear 20. The connecting plate 15 is rotatably connected to the lower side of the adjusting plate 1 via a rotating shaft. The I-beam support plate 16 is fixed below the connecting plate 15. The battery 17 and the third motor 18 are respectively installed on both sides of the I-beam support plate 16. The output shaft end of the third motor 18 is connected to the third gear 19. The third gear 19 meshes with the semi-circular gear 20, which is fixed to the lower side of the adjusting plate 1.
[0028] Working principle: Start motor 318, through the meshing transmission of gear 319 and semi-circular gear 20, drive adjustment plate 1 to rotate around the shaft of connecting plate 15, thereby adjusting the angle of toothed hob cutter blank 3 to meet different marking requirements.
[0029] The mobile spraying assembly includes a linear slide rail 21, a support frame 22, a second linear slide rail 23, a paint tank 24, a pump body 25, a first conduit 26, a second conduit 27, and a spray marking head 28. The first linear slide rail 21 is horizontally fitted onto one side of the adjusting plate 1, and the support frame 22 is slidably connected to the first linear slide rail 21. The second linear slide rail 23 is located on one side of the support frame 22. The paint tank 24 is fixed to the other side of the support frame 22. The pump body 25 is installed inside the paint tank 24, with its input end connected to the paint tank 24 via the first conduit 26, and its output end connected to the spray marking head 28 via the second conduit 27. The spray marking head 28 is slidably connected to the second linear slide rail 23.
[0030] Working principle: When the pump body 25 is started, the paint is transported from the paint tank 24 through the first conduit 26 and the second conduit 27 to the spray marking head 28. By controlling the movement of the first linear slide rail 21 and the second linear slide rail 23, the spray marking head 28 is driven to move precisely in the horizontal and vertical directions, realizing the automated marking of the toothed hob drill bit blank 3.
[0031] The working principle of this utility model is as follows: First, the toothed hob cutter blank 3 is clamped on the three-jaw chuck 9. The controller 2 starts the motor 6, which drives the gear 7 to rotate. The gear 7 meshes with the gear 8, thereby driving the three-jaw chuck 9 to rotate and adjust the toothed hob cutter blank 3 to a suitable circumferential angle.
[0032] Next, start motor 2 13. Motor 2 drives threaded rod 14 to rotate. Slide plate 11 moves along threaded rod 14 in slide groove 10, driving toothed hob cutter blank 3 to move horizontally. At the same time, turntable 12 can be rotated as needed to further fine-tune the angle of toothed hob cutter blank 3 to complete precise positioning and fixing.
[0033] After positioning is completed, according to the marking requirements, start motor three 18. Motor three drives gear three 19 to rotate. Gear three meshes with semi-circular gear 20, causing adjustment plate 1 to rotate around connecting plate 15, thereby realizing the angle flipping of the toothed hob cutter blank 3 and adjusting it to a suitable marking angle.
[0034] Finally, the pump body 25 is started, and the pump body draws the paint in the paint tank 24 through the first conduit 26, and then delivers it to the spray marking head 28 through the second conduit 27. At the same time, the spray marking head 28 is driven by the first linear slide rail 21 and the second linear slide rail 23 to move and spray marking on the toothed hob cutter blank 3 according to the preset trajectory, thus completing the entire marking process.
[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
