Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drilling auxiliary tooling, in particular to a drilling piece fixing structure. Background Art
[0002] During machining, drilling holes in pipes is a common operation. This requires the use of a bench drill, which uses the rotation and cutting action of the drill bit to create holes in the pipes.
[0003] During the drilling process, the pipe needs to be placed on the workbench of a bench drill. The spindle of the bench drill drives the drill bit to rotate and penetrate the interior of the pipe to form the desired hole. However, in actual operation, especially for slender pipes, it is very easy to deviate from the predetermined position when drilling, which can lead to reduced drilling accuracy and even damage to the pipe. To address this problem, operators consider using a clamp to clamp the pipe, but this is not suitable for bench drills. Therefore, in traditional practice, when using a bench drill to drill a pipe, the operator is often required to manually fix the pipe.
[0004] During the implementation process, the inventors found that the above-mentioned existing technology has at least the following defects: manual fixing of pipe fittings by operators is not only inconvenient, but also poses a high safety risk during the hole-making process. Once improper operation or an accident occurs, it is easy to cause injury to the operator. Utility Model Content
[0005] The embodiment of the present application solves the technical problem in the prior art of requiring operators to manually fix pipe fittings during drilling with a bench drill by providing a drill fitting fixing structure, thereby effectively reducing the difficulty of operation and avoiding safety hazards.
[0006] In order to solve the above technical problems, the utility model adopts the following technical solution: a drill fixing structure, including a base, a first screw rod is vertically installed on the base, a connecting nut A is installed on the first screw rod, one side of the connecting nut A is connected to a connecting nut B through a connecting rod, a second screw rod is fitted in the connecting nut B, and a handle is fixed to the upper end of the second screw rod.
[0007] When using the utility model, the first screw is first adjusted to a suitable position and fixed to the base. Then, the pipe is placed, the handle is rotated to press the lower end of the second screw against the top of the pipe, and finally the table drill is used to drill a hole in the pipe. During the drilling process, the operator does not need to manually fix the pipe, so the operation is more convenient and reduces safety hazards.
[0008] Furthermore, the base is a channel steel, and the two wing plates of the channel steel can be fixed to the workbench of the bench drill. The bottom plate of the channel steel is fixed to the lower end of the first screw, and the wing plates of the channel steel and the workbench can be fixed by welding.
[0009] Furthermore, a strip hole is provided on the bottom plate of the channel steel for the lower end of the first screw to pass through, and a fixing nut and a fastening nut are installed on the lower end of the first screw, and the bottom plate of the channel steel is pressed between the fixing nut and the fastening nut; therefore, when the position of the first screw needs to be adjusted, the fastening nut can be loosened to allow the first screw to move laterally along the strip hole.
[0010] Furthermore, the connecting nut A and the connecting nut B are both two stacked M12 nuts, and the two ends of the connecting rod are respectively welded and fixed to the two stacked M12 nuts; thereby, the connection strength between the connecting rod and the connecting nut A or the connecting nut B can be improved.
[0011] Furthermore, the handle is a gasket, and the outer periphery of the gasket is welded and fixed to the top of the second screw.
[0012] Furthermore, a spring washer is provided between the fastening nut and the base; thereby, the stability of the first screw can be improved.
[0013] It can be seen from the above technical solutions that the present invention has at least the following technical effects or advantages:
[0014] When using the utility model, the first screw is first adjusted to a suitable position and fixed to the base. Then, the pipe is placed, the handle is rotated to press the lower end of the second screw against the top of the pipe, and finally the table drill is used to drill a hole in the pipe. During the drilling process, the operator does not need to manually fix the pipe, so the operation is more convenient and reduces safety hazards. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of this patent, other embodiments obtained by ordinary technicians in this field without making creative work are all within the scope of protection of this patent.
[0021] The utility model discloses a drill fixing structure, such as Figure 1 As shown, it includes a base 1, a first screw rod 2, and a second screw rod 3. The lower end of the first screw rod 2 is fixed relative to the base 1. The first screw rod 2 and the second screw rod 3 are respectively installed with a connecting nut A4 and a connecting nut B5. The connecting nut A4 and the connecting nut B5 are connected by a horizontal connecting rod 6. In one example, the base 1 can be fixed to the workbench of the bench drill, and the second screw rod 3 can be rotated so that the lower end of the second screw rod 3 is pressed against the pipe 10 to be drilled. Then, the bench drill can be operated to drill the hole.
[0022] The base 1 is a channel steel, the two wings of which face downwards and can be fixed to the workbench of the bench drill. The bottom plate of the channel steel is used to fix the lower end of the first screw 2. When the first screw 2 is fixed to the base 1, the first screw 2 is in a vertical state. Figure 1 As shown in FIG, a strip hole is provided on the bottom plate of the channel steel for the lower end of the first screw rod 2 to pass through. After the lower end of the first screw rod 2 passes through the strip hole, it is tightened with the fixing nut 8. Figure 2 As shown, a fastening nut 7 is also installed at the lower end of the first screw rod 2, and the fastening nut 7 is located above the fixing nut 8. When the first screw rod 2 is fixed to the base 1, the fastening nut 7 and the fixing nut 8 are respectively located on the upper and lower sides of the channel steel bottom plate, thereby enabling the first screw rod 2 to be fixed to the base 1 through the fastening nut 7 and the fixing nut 8. When the position of the first screw rod 2 needs to be adjusted, the fastening nut 7 can be loosened to allow the first screw rod 2 to move laterally along the strip hole, and then the fastening nut 7 can be tightened. In addition, a spring washer (not shown in the figure) can be provided between the fastening nut 7 and the bottom plate of the channel steel, and the spring washer can be used to improve the stability of the first screw rod 2.
[0023] like Figure 1 、 Figure 2 As shown, in this embodiment, the connecting nut A4 and the connecting nut B5 are two stacked M12 nuts, and the two ends of the connecting rod 6 are welded to the two stacked M12 nuts. This allows the use of a connecting rod 6 with a larger diameter, and the welding of the ends of the connecting rod 6 to the connecting nut A4 or the connecting nut B5 can be more secure.
[0024] In this embodiment, a handle 9 is fixed to the upper end of the second screw rod 3. The handle 9 is a gasket, and the outer periphery of the gasket is welded and fixed to the top of the second screw rod 3. This makes it easier to obtain materials and saves manufacturing costs of this structure.
[0025] Figure 3 This is a schematic diagram of the utility model during use. Figure 3 As shown, when in use, the specific operations are as follows:
[0026] First, adjust the first screw rod 2 to the appropriate position and fix it to the base 1. Then place the pipe 10, rotate the handle 9, so that the lower end of the second screw rod 3 is pressed against the top of the pipe 10, and finally use the bench drill to drill a hole in the pipe 10. During the drilling process, the operator does not need to manually fix the pipe 10, so the operation is more convenient and reduces safety hazards.
