Description

Technical Field

[0001] This utility model relates to the field of drill bit inspection technology, and in particular to a dimensional measuring tool for sharpened drill bits. Background Art

[0002] Twist drills are the most widely used hole-making tools in the mechanical manufacturing industry. As the number of drilling operations increases, twist drills will wear down. Wear-down twist drills will cause a decrease in hole accuracy when drilling. Therefore, twist drills need to be sharpened multiple times before they can be used again.

[0003] A search revealed that utility model patent CN221792302U discloses an auxiliary testing device for grinding twist drills, comprising a main body, a movable body, and an adjusting rod. The main body consists of a base, a vertical rod perpendicular to the base, and an inclined rod formed on the vertical rod. There is a guide rail groove on the base and in the center of the inclined rod. The vertical rod, the inclined rod, and the two guide rail grooves are all on the same plane. Below the inclined rod is an inclined surface for measuring one cutting edge of the twist drill bit. The movable body is a flat, elongated strip, vertically installed in the guide rail groove on the base of the main body. Its upper part folds towards the main body at the same height as the vertical rod and inserts into the guide rail groove of the upper inclined rod of the main body.

[0004] However, the above-mentioned testing device still has some shortcomings in actual use. The most obvious one is that during the testing process, since the tester needs to operate the screw with one hand, the twist drill under test can only be kept in a vertical position with one hand. This is difficult to operate and consumes a lot of manpower. In addition, it cannot ensure that the twist drill is in a vertical position, and the testing accuracy is not ideal.

[0005] Therefore, it is necessary to invent a dimensional measuring tool for grinding drill bits to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a dimensional measuring tool for sharpened drill bits, which can clamp and inspect twist drills of different specifications, thus having a wider range of applications. It also ensures that the twist drill remains relatively stable during inspection, improving inspection accuracy while reducing inspection difficulty. This makes it more convenient to use in practice, addressing the problem mentioned in the background art where, during the inspection process, the operator needs to use one hand to operate the screw, thus requiring one hand to keep the twist drill in a vertical position, which is difficult and labor-intensive. Furthermore, it cannot guarantee that the twist drill will remain vertical, resulting in insufficient inspection accuracy.

[0007] According to one aspect of this disclosure, the following technical solution is provided: a dimensional measuring tool for grinding drill bits, comprising:

Compared to existing similar equipment, this invention can clamp and test twist drills of different specifications, making it more applicable. It also maintains a more stable state during testing, improving accuracy while reducing testing difficulty, making it more convenient in actual use. Attached Figure Description

[0033] Figure 2 This is a schematic diagram of the mounting mechanism 1 and the detection mechanism 2 of a dimensional measuring tool for grinding drill bits according to one embodiment of the present disclosure.

[0034] Figure 3 This is a schematic diagram of the clamping mechanism 3 of a dimensional measuring tool for grinding drill bits according to one embodiment of the present disclosure.

[0035] like Figures 1-3 As shown, the dimensional measuring tool for grinding drill bits disclosed herein may include components such as a mounting mechanism 1, a measuring mechanism 2, and a clamping mechanism 3.

[0036] like Figure 2 As shown in this disclosure, the installation mechanism 1 includes an installation plate 11, support legs 12, and pads 13. There are two support legs 12, which are fixedly installed at both ends of the bottom of the installation plate 11. There are two pads 13, which are fixedly installed at the bottom ends of the two support legs 12.

[0037] like Figure 2 As shown, in a preferred embodiment, the detection mechanism 2 includes a first U-shaped seat 21, a bidirectional screw 22, a first knob 23, a first moving plate 24, a second moving plate 25, a first inclined clamping plate 26, a second inclined clamping plate 27, and a clearance channel 28. The first U-shaped seat 21 is fixedly disposed on the top left end of the mounting plate 11. The bidirectional screw 22 passes through the inner side of the first U-shaped seat 21 and is rotatably connected to it via a bearing. The first knob 23 is fixedly disposed at the end of the bidirectional screw 22. The first moving plate 24... The first movable plate 24 and the second movable plate 25 are respectively sleeved on the outer ends of the bidirectional screw 22. The first movable plate 24 and the second movable plate 25 are both threadedly connected to the bidirectional screw 22. The first movable plate 24 and the second movable plate 25 are both slidably connected to the inner wall of the first U-shaped seat 21. The second inclined clamping plate 27 is fixedly disposed on the left side of the first movable plate 24. The clearance channel 28 is fixedly disposed on the left side of the second movable plate 25. The clearance channel 28 is opened on the side of the second inclined clamping plate 27. The first inclined clamping plate 26 is slidably disposed on the inner side of the clearance channel 28.

[0038] Therefore, by rotating the bidirectional screw 22 through the first knob 23, the first moving plate 24 and the second moving plate 25 can drive the first inclined clamping plate 26 and the second inclined clamping plate 27 to move closer to each other. Finally, it can be observed whether the inclined surface of the cutting edge of the twist drill under test is in contact with the inner wall of the first inclined clamping plate 26 and the second inclined clamping plate 27, so as to determine whether the twist drill under test is qualified.

[0039] like Figure 3As shown in this disclosure, the clamping mechanism 3 includes a second U-shaped seat 31, a first clamping roller 32, a third U-shaped seat 33, a second clamping roller 34, a U-shaped frame 35, a one-way screw 36, a second knob 37, and a guide rod 38. The second U-shaped seat 31 is fixedly mounted on the top right side of the mounting plate 11. Two first clamping rollers 32 and two second clamping rollers 34 are each provided. The two first clamping rollers 32 are rotatably nested inside the second U-shaped seat 31 via bearings, and are arranged parallel to each other. The third U-shaped seat 33 is located directly above the second U-shaped seat 31. The two second clamping rollers 34 are... The holding rollers 34 are all nested inside the third U-shaped seat 33 via bearings. The two second clamping rollers 34 are arranged parallel to each other. The U-shaped frame 35 is located outside the second U-shaped seat 31 and the third U-shaped seat 33 and is fixedly connected to the mounting plate 11. The one-way screw 36 is threaded through the top right side of the U-shaped frame 35 and is threadedly connected to the U-shaped frame 35. The bottom end of the one-way screw 36 is nested inside the top of the third U-shaped seat 33 via bearings. The second knob 37 is fixedly located at the top end of the one-way screw 36. The guide rod 38 is slidably threaded through the top left side of the U-shaped frame 35 and is fixedly connected to the third U-shaped seat 33.

[0040] This allows the sharpened twist drill to be placed on top of the two first clamping rollers 32, which support the drill. Then, the second knob 37 drives the one-way screw 36 to rotate. As the one-way screw 36 rotates, it causes the third U-shaped seat 33, guided by the guide rod 38, to move continuously downward. After the third U-shaped seat 33 moves downward, it is clamped and fixed by the two second clamping rollers 34. Compared with existing similar equipment, this method can clamp and test twist drills of different specifications, making it more applicable. At the same time, it can keep the tested twist drill in a relatively stable state during the testing process, improving the testing accuracy while reducing the testing difficulty, making it more convenient in actual use.

[0041] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0042] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
