Technical Field

[0001] This utility model relates to a stepped drill bit, specifically a stepped drill bit with laser alignment marks, belonging to the field of stepped drill bit technology. Background Technology

[0002] A step drill is a drilling tool with a unique structure and purpose. Its main characteristic is the stepped shape of its drill bit. It consists of multiple cylindrical sections of varying diameters connected together, with the diameter gradually increasing from the tip to the shank, forming a step-like shape. The diameter of each step typically increases according to a specific specification, commonly with 2-3 steps, but sometimes as many as 5-6 steps, to meet different drilling needs.

[0003] In the prior art, such as the drilling positioning device for mold frame processing disclosed in announcement number CN212470665U, this utility model is fixedly installed on the drilling head during use. The central axes of the two laser generators are on the same plane as the central axis of the drill bit. The laser generators are located on both sides of the drill bit and are symmetrical about the drill bit. The rotating fixed part and the laser generator are controlled to rotate by a co-rotating device, so that the laser beam of the laser generator rotates closer to the drill bit. The intersection point of the laser beams emitted by the laser generator is the drilling position of the drill bit. The structure is simple, the drilling position is convenient, the production efficiency is improved, and the production yield is increased.

[0004] However, in implementing the relevant technology, the drilling positioning device for mold frame processing designed above has the following problems: In the prior art, the combination of components such as laser generator can perform drilling positioning, but in the actual use process, the laser generator is set on the outer wall of the drill bit, which makes the positioning operation more troublesome and inconvenient to disassemble and replace. In view of this, a stepped drill bit with laser alignment mark is provided to overcome the above defects. Utility Model Content

[0005] This invention addresses the problem that the laser generator is located on the outer wall of the drill bit, making positioning cumbersome and disassembly / replacement inconvenient. It provides a stepped drill bit with laser alignment marks.

[0006] The present invention achieves the above objectives through the following technical solution: a stepped drill bit with laser alignment marks, comprising a drill rod, the bottom end of which has a drill bit protruding, and a limit groove is formed inside the drill rod, and a sliding groove is formed on the outer wall of the drill rod, and an adjustment mechanism is provided inside the sliding groove.

[0007] The adjustment mechanism includes a sleeve, which is slidably connected to one side of the limiting groove on the outer wall of the drill rod. The inner wall of the sleeve is provided with a slot, and a locking block is slidably connected inside the slot. A connecting plate is fixedly installed at one end of the locking block that protrudes from the slot.

[0008] As a further embodiment of this utility model: a mounting block is fixedly installed at one end of the connecting plate, and a laser light extends from the inside of the mounting block, and a storage battery is fixedly installed at the top of the laser light.

[0009] As a further embodiment of this utility model: the laser lamp is threadedly connected to the mounting block, and the mounting block forms a rotating structure with the sleeve through the locking block and the connecting plate.

[0010] As a further improvement of this utility model: a mounting groove is provided below the sliding groove on the outer wall of the drill rod, and a connecting mechanism is provided inside the mounting groove.

[0011] As a further embodiment of this utility model: the connecting mechanism includes a rotating plate, which is rotatably connected to the inside of the mounting groove, and a support shaft extends through the inside of the rotating plate, and a limit block is fixedly installed on the lower outer wall of the rotating plate.

[0012] As a further improvement of this utility model: the outer wall of the drill bit is provided with a penetration groove, and the inner wall of the penetration groove is provided with a positioning groove.

[0013] As a further improvement of this utility model: a positioning block is fixedly installed at one end of the drill bit that penetrates the drill rod, and a through hole is provided inside the positioning block.

[0014] The beneficial effects of this utility model are as follows: Firstly, the limiting groove and sliding groove opened in the drill rod allow the connecting plate and mounting block to pass through and slide. At the same time, the slot and locking block allow the sleeve to adjust its position by connecting it to the drill rod threadedly. This allows the laser lamp to slide inside the drill rod and be aligned with the center point of the drill bit. The laser can be directed towards the workpiece from the center point of the drill bit, thereby improving the accuracy of the processing. In addition, the laser lamp is threadedly connected to the mounting block and the sleeve is threadedly connected to the drill rod, which allows for quick disassembly and maintenance of the laser lamp, improving the overall flexibility and applicability of use.

[0015] The rotating plate rotates inside the mounting slot via the support shaft, allowing it to enter the through slot opened by the drill bit. The limiting block enters the positioning slot for positioning, and after adjusting the position with the sleeve, the rotating plate is closed. This allows for quick assembly and disassembly of the drill rod and drill bit, facilitating replacement when the drill bit is damaged. The positioning block also allows the internal limiting slot of the drill rod to limit the drill bit, increasing the torque force of the drill rod on the drill bit. Furthermore, the through hole allows the laser light to penetrate the positioning block and the drill bit to irradiate the workpiece. Attached Figure Description

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0023] like Figures 1 to 5As shown, a stepped drill bit with laser alignment marks includes a drill rod 1, with a drill bit 2 extending from the bottom end of the drill rod 1. A limiting groove 3 is formed inside the drill rod 1, and a sliding groove 4 is formed on the outer wall of the drill rod 1. An adjustment mechanism 5 is disposed inside the sliding groove 4. The adjustment mechanism 5 includes a sleeve 501, which is slidably connected to one side of the limiting groove 3 on the outer wall of the drill rod 1. A slot 502 is formed on the inner wall of the sleeve 501, and a locking block 503 is slidably connected inside the slot 502. A connecting plate 504 is fixedly installed at one end of the locking block 503 extending out of the slot 502, and an mounting block 505 is fixedly installed at one end of the connecting plate 504. A laser lamp 506 extends from inside the mounting block 505, and a battery 507 is fixedly installed at the top of the laser lamp 506. The laser lamp 506 and the mounting block 505 are connected... 5. Threaded connection: Mounting block 505 forms a rotating structure with sleeve 501 through locking block 503 and connecting plate 504. First, the limiting groove 3 and sliding groove 4 opened in the drill rod 1 allow the connecting plate 504 and mounting block 505 to pass through and slide. At the same time, the locking groove 502 and locking block 503 allow the sleeve 501 to adjust its position by threaded connection with the drill rod 1. This allows the laser lamp 506 to slide inside the drill rod 1 and be aligned with the center point of the drill bit 2. The laser can be directed towards the workpiece with the center point of the drill bit 2, thereby improving the accuracy of the processing. At the same time, the laser lamp 506 is threadedly connected to mounting block 505 and threadedly connected to drill rod 1 with sleeve 501, which allows for quick disassembly and maintenance of the laser lamp 506, improving the overall flexibility and applicability of use. Example 2

[0024] In addition to all the technical features included in Embodiment 1, this embodiment also includes: a mounting groove 6 is provided below the sliding groove 4 on the outer wall of the drill rod 1; a connecting mechanism 7 is provided inside the mounting groove 6; the connecting mechanism 7 includes a rotating plate 701, which is rotatably connected to the inside of the mounting groove 6; a support shaft 702 extends through the inside of the rotating plate 701; a limit block 703 is fixedly installed on the lower outer wall of the rotating plate 701; an insertion groove 704 is provided on the outer wall of the drill bit 2; a positioning groove 705 is provided on the inner wall of the insertion groove 704; a positioning block 706 is fixedly installed at one end of the drill bit 2 that penetrates the drill rod 1; and a through hole 7 is provided inside the positioning block 706. 07; The rotating plate 701 is rotated inside the mounting groove 6 by the support shaft 702, so that it can enter the through groove 704 opened in the drill bit 2, and the limiting block 703 enters the positioning groove 705 for positioning. After adjusting the position with the sleeve 501, the rotating plate 701 is closed, which allows the drill rod 1 and the drill bit 2 to be quickly disassembled and assembled, which is convenient for replacement when the drill bit 2 is damaged. With the help of the positioning block 706, the limiting groove 3 inside the drill rod 1 can limit the drill bit 2, increase the torque of the drill rod 1 on the drill bit 2, and with the help of the through hole 707, the laser of the laser lamp 506 can penetrate the positioning block 706 and the drill bit 2 to irradiate the workpiece.

[0025] Working principle: Through the limiting groove 3 and the sliding groove 4, the sleeve 501, connecting plate 504, and mounting block 505 are inserted into the drill rod 1, maintaining the limiting position during sliding. The sleeve 501 can be rotated through the slot 502 and the locking block 503. The position is adjusted by the threaded connection with the drill rod 1 until the laser lamp 506 abuts against the positioning block 706 at the top of the drill bit 2 and is aligned with the through hole 707. This allows the laser to be projected onto the workpiece from the center point of the drill bit 2, improving accuracy and facilitating disassembly and replacement. At the same time, the laser lamp 506 is connected to the mounting block 505 by the threaded connection. For easy disassembly and maintenance, the laser light 506 is equipped with a rechargeable battery 507 to prevent cable connections from affecting the rotation of the drill rod 1. The rotating plate 701 inside the mounting slot 6 is rotated via the support shaft 702, thereby entering the insertion slot 704 and allowing the limiting block 703 to enter the positioning slot 705. The rotating plate 701 is closed under the adjustment of the sleeve 501, which enables quick disassembly and replacement when the drill bit 2 is damaged. The positioning block 706 at the top of the drill bit 2 is inserted into the limiting slot 3 of the drill rod 1, further increasing the torque force of the drill rod 1 on the drill bit 2 during rotation.
