Description

Technical Field

[0001] The invention relates to the technical field of hardware drilling, in particular to a hardware positioning drilling device. Background Art

[0002] Hardware, as an indispensable basic component in the manufacturing industry, is widely used in many fields such as construction, machinery, electronics, furniture, etc. They are usually made of metal materials, including but not limited to steel, aluminum alloy, copper, etc., with the characteristics of high strength and good durability. In the processing of hardware, drilling is a crucial link, which is directly related to the accuracy of subsequent assembly and the overall performance of the product;

[0003] Traditionally, hand drills are widely used as portable and flexible tools for drilling holes in hardware. Hand drills are easy to operate and widely applicable, showing great value in small-scale production or on-site maintenance. However, when faced with hardware processing that requires precise control of hole position and hole diameter, the use of hand drills reveals its limitations.

[0004] On the one hand, the drilling position of hardware often needs to be accurately set according to the design requirements. The traditional method usually relies on manual measurement with a ruler to determine the spacing between two or more holes. This method is not only inefficient, but also difficult to ensure accuracy. It is easy to introduce errors due to human factors, thus affecting the overall quality and assembly effect of the product. Especially in the processing of precision hardware with high precision requirements, this error is often fatal;

[0005] On the other hand, the surface of hardware is usually smooth. While this feature brings beauty, it also brings considerable trouble to the drilling operation. The smooth surface makes it difficult for the drill bit to cut into the material stably in the initial stage, and it is very easy to slip. This not only increases the difficulty and effort of drilling, but may also cause damage to the drill bit or scratches on the surface of the hardware, affecting the appearance and service life of the product. In addition, since the smooth surface reduces the friction between the drill bit and the hardware, the stability of the drill bit during the drilling process is affected, further aggravating the generation of errors.

[0037] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0038] When in use, if it is necessary to drill holes in hardware pipes, place the hardware pipes in the inner cavities of the first positioning groove 3 and the third positioning groove 11, rotate the screw 4, and the rotational force generated by the rotation of the screw 4 can prompt the clamping block 5 to move downward until the hardware pipes are clamped and fixed by the clamping block 5, and the hardware frame pipes can be positioned by using the cooperation between the first positioning groove 3 and the second positioning groove 7, insert the top end of the rotating rod 18 into the chuck of the hand drill, slide the drilling plate 10 to the right until the position of the drill bit 20 corresponds to the position where the hardware pipe needs to be drilled, rotate the first positioning bolt 13, prompt the first positioning rubber 14 and the first guide rod 9 to contact firmly, and use the friction between the first positioning rubber 14 and the first guide rod 9 to drill the drilling plate 10 The position of the outer cylinder 81 can be fixed. For example, when only one hole needs to be punched on the pipe, the fourth guide rod 27 can be slid upward until the top of the fixing plate 29 contacts the bottom of the slide plate 22, and the second positioning bolt 23 is rotated to cause the second positioning rubber 24 to contact the fourth guide rod 27 firmly, so that the position of the outer cylinder 81 can be fixed by using the friction between the second positioning rubber 24 and the fourth guide rod 27 to ensure that the punching needle 82 does not contact the hardware pipe. If multiple holes need to be punched, the slide plate 22 is slid along the outer wall of the third guide rod 21, and the position of the slide plate 22 is read through the scale line 28 until the slide plate 22 moves to a suitable position, and the third positioning bolt 25 is rotated to cause the third positioning rubber 26 to contact the third guide rod 21 firmly, and the third positioning rubber 26 is used to fix the outer cylinder 81. The friction between the third guide rod 21 and the slide plate 22 can fix the position of the slide plate 22, slide the fourth guide rod 27 up and down, and read the height of the outer cylinder 81 through the scale line 28 until it moves to a suitable height, rotate the second positioning bolt 23, and make the second positioning rubber 24 and the fourth guide rod 27 firmly contact, and then use the friction between the second positioning rubber 24 and the fourth guide rod 27 to fix the height of the outer cylinder 81, press the hand drill downward, use the hand drill to drive the pressure plate 17 and the drill bit 20 to move downward, and squeeze the first spring 16 to cause elastic deformation, and at the same time use the hand drill to cause the drill bit 20 to rotate until the drill bit 20 contacts the pipe, and then the rotating drill bit 20 can be used to drill the pipe, when the pressure plate 17 moves down to the punching needle 82 The punching needle 82 contacts the outer wall of the tube, and the outer wall of the tube can be used to squeeze the punching needle 82 to move into the inner cavity of the outer tube 81, and squeeze the second spring 84 to cause elastic deformation.

At the same time, the second limiting rod 812 is prompted to move into the inner cavity of the telescopic groove 83 until it moves to the pulley 811 and contacts the second baffle 816. The punching needle 82 continues to push the support seat 85 to move upward, and the second baffle 816 can be used to prompt the block 89 to move into the inner cavity of the telescopic tube 87.The fourth spring 810 is squeezed to undergo elastic deformation until the block 89 and the knocking hammer 814 are separated, and the fifth spring 813 is used to push the knocking hammer 814 to move downward until the knocking hammer 814 contacts the punching needle 82, and then the knocking hammer 814 can be used to knock the punching needle 82, so that the punching needle 82 can be used to generate a concave hole on the surface of the pipe, which is convenient for positioning the hole position and for the drill bit to cut into the pipe, until the punching needle 82 can no longer push the support seat 85 to move upward, at which time the drill bit 20 can no longer deepen the drilling depth of the pipe, and the hand drill is lifted upward, and the pressure plate 17 can be pushed upward to the initial position under the elastic force of the first spring 16. At the same time, the upward movement of the pressing plate 17 can drive the sliding plate 22 and the outer cylinder 81 to move upward through the third guide rod 21. The outer cylinder 81 moves upward, and the second spring 84 can be used to push the punching needle 82 to return to the initial position, and the fifth spring 813 can be used to push the knocking hammer 814 to move downward to the initial position, and the first baffle 815 can be used to block the knocking hammer 814, and the third spring 86 can be used to pull the support seat 85 to move downward. The separation of the block 89 and the second baffle 816 will push the block 89 to move out of the inner cavity of the telescopic cylinder 87 under the elastic force of the fourth spring 810 until it returns to the initial position. As the support seat 85 drives the block 89 to move downward, when the block When the bottom end of block 89 contacts the top end of hammer 814, the top end of hammer 814 is used to squeeze the bottom end of block 89, so that block 89 moves toward the inner cavity of telescopic cylinder 87 and squeezes fourth spring 810 to elastically deform until the bottom end of block 89 and the top end of hammer 814 are separated. Under the elastic force of fourth spring 810, block 89 can be pushed to return to the initial position. Thus, when support seat 85 moves upward, block 89 can be used again to push hammer 814 to move upward, so as to complete the drilling of pipe. When the next drilling is needed, the drilling plate 10 is slid to the right until the drill bit 20 moves to the punching position of punching needle 82. , you can repeat the above actions to drill again. When you need to drill a hole in a hardware plate, place the positioning seat 1 and the drilling plate 10 on the top of the plate, and press the positioning seat 1 with one hand. Repeat the above actions to complete the drilling of the hardware plate.
