Description

Technical Field

[0001] This utility model relates to the field of drill bit processing technology, and in particular to a drill bit processing positioning fixture. Background Technology

[0002] A drill bit is a cutting tool used in drills or drilling machines to cut circular holes. The basic principle of a drill bit is to rotate its cutting edge, cut the workpiece, and then remove drill chips through the drill groove. Commonly used drill bits include twist drills, flat drills, center drills, deep hole drills, and casing drills. Drill bits require positioning fixtures for fixation during manufacturing.

[0003] Currently, most drill bit positioning fixtures do not have a rotation adjustment function during use. This means that after the drill bit is clamped and fixed, its position is relatively fixed. When the outer surface of the drill bit needs to be processed, it is necessary to constantly release the clamp for adjustment and then clamp it again, which significantly affects the processing efficiency of the drill bit and reduces the overall practicality of the device.

[0004] Therefore, it is necessary to provide a drill bit machining positioning fixture to solve the above-mentioned technical problems. Utility Model Content

[0030] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0031] According to one embodiment of the present invention, in conjunction with Figure 1-4As shown. A drill bit machining positioning fixture includes: a base 1, with two support frames 2 on the top of the base 1. An adjusting ring 3 is rotatably connected inside each support frame 2. A bidirectional threaded rod 4 is rotatably connected to the adjusting ring 3. Two clamping plates 5 are threaded to the outer surface of the bidirectional threaded rod 4. A toothed ring 6 is fixedly connected to the outer surface of the adjusting ring 3. A rotating shaft 7 is rotatably connected to one side of each of the two support frames 2. A guide rod 11 is fixedly connected inside the adjusting ring 3 and movably connected to the two clamping plates 5. Gears 8 are fixedly sleeved on the outer surface of each of the two rotating shafts 7, and the gears 8 mesh with the toothed rings 6. A square telescopic rod 9 is fixedly connected between the opposite sides of the two rotating shafts 7. One of the support frames 2 is fixedly mounted on one side with a motor 10. The output end of the motor 10 is fixedly connected to the other end of one of the rotating shafts 7. The base 1 is equipped with a support assembly and a moving assembly. Through the cooperation of the base 1, support frame 2, adjusting ring 3, clamping plate 5, gear ring 6, gear 8, square telescopic rod 9, moving groove 15 and motor 18, the drill bit can be clamped and driven to rotate, so that the drill bit can be rotated for processing. At the same time, during the processing, the clamping position can be easily changed to process the clamping part, avoiding the clamping part from affecting the overall processing of the drill bit, improving the processing efficiency of the drill bit, and thus improving the overall practicality of the device.

[0032] In this embodiment, the top of the base 1 is provided with a plurality of slots 12, which are arranged in a linear array. The support assembly includes a plurality of elastic telescopic rods 13, which are all mounted on the base 1. The top of each elastic telescopic rod 13 is fixedly connected to a support plate 19. The elastic telescopic rods 13 are square in shape, and the bottom of each elastic telescopic rod 13 is movably inserted into one of the slots 12 through a square block 14. Through the coordinated use of the base 1, the slots 12, and the square block 14, the elastic telescopic rods 13 and the support plate 19 can be prevented from obstructing the position adjustment of the support frame 2 and other structures. At the same time, they can be easily moved to the required position to support the drill bit to be clamped, keeping the clamped drill bit horizontal and further improving the practicality of the device.

[0033] In this embodiment, a movable groove 15 is provided on the top of the base 1. Two movable blocks 16 are slidably connected inside the movable groove 15. The tops of the two movable blocks 16 are fixedly connected to the bottoms of the two support frames 2 respectively. By setting the movable groove 15 and the movable blocks 16, the movement of the support frame 2 can be guided and limited, so that it can move horizontally.

[0034] In this embodiment, the moving component includes a bidirectional threaded rod 17 and a motor 18. The bidirectional threaded rod 17 is rotatably connected inside the moving groove 15 and is threadedly connected to two moving blocks 16 respectively. The motor 18 is fixedly installed on one side of the base 1, and the output end of the motor 18 is fixedly connected to one end of the bidirectional threaded rod 17. By setting the moving component, the positions of the two support frames 2 and the adjusting ring 3 can be adjusted according to the length of the drill bit, so that the distance between the two support frames 2 can be increased or decreased.

[0035] Working principle: During operation, the positions of the two support frames 2 can be adjusted according to the length of the drill bit to be clamped. The elastic telescopic rod 13 is manually lifted and pulled out from the base 1 to avoid obstructing the movement of the support frame 2. Then, the motor 18 is started to drive the bidirectional threaded rod 17 to rotate. With the cooperation of the moving groove 15, the two moving blocks 16 can drive the corresponding support frame 2, adjusting ring 3, gear ring 6 and gear 8 to move relative to or away from each other. At the same time, during the movement, the telescopic end of the square telescopic rod 9 is contracted or extended, so that the usage position of the two support frames 2 can be adjusted. Then, the elastic telescopic rod 13 is reinserted into the corresponding position for use. When clamping the drill bit, it is first placed on the support plate 19. Then, the bidirectional threaded rod 4 can be rotated. Under the guidance and limit of the guide rod 11, the two clamping plates 5 can move relative to each other, so that the drill bit can be clamped from one side.

[0036] When machining the drill bit, the support plate 19 can be pressed down to lower it, and the elastic telescopic rod 13 can be pulled out again to avoid obstructing the machining work of the drill bit. At the same time, when the drill bit needs to be rotated during the machining process, the motor 10 is started to drive the gear 8 of the corresponding rotating shaft 7 to rotate. With the cooperation of the square telescopic rod 9, another rotating shaft 7 and gear 8 can be rotated. Gear 8 drives the corresponding gear ring 6 to rotate, gear ring 6 drives the adjusting ring 3 to rotate, and adjusting ring 3 drives the bidirectional threaded rod 4, guide rod 11, clamping plate 5 and the clamped drill bit to rotate synchronously, so that the drill bit can be rotated for machining. When the clamped area needs to be machined during the machining process, the area after the drill bit has been machined can be clamped by the clamping plate 5 on the other side, and the clamping plate 5 on the other side can be released to drive the drill bit to rotate again for machining of the obstructed area.

[0037] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
