Description

Technical Field

[0001] This utility model relates to the field of drilling device technology, specifically to a pipe positioning drilling device. Background Technology

[0002] In the existing technology, when using a drilling machine, the drilling position and size markings are measured and marked on the surface of the pipe according to the design requirements. The pipe to be drilled is placed in the table fixture, and the drilling position is determined by fine-tuning the "XYZ" axis of the drill bit. This drilling technology is mainly suitable for small and medium-sized pipe diameters and shorter pipe fittings.

[0003] The objective drawbacks of existing technologies are that they are difficult to meet the requirements for drilling straight holes in pipelines. For situations where multiple holes need to be drilled in a pipeline, drilling marks must be made on the pipe, and the fixture must be constantly moved and re-fixed, resulting in low processing efficiency, especially noticeable with large-diameter or long pipes. Furthermore, drilling accuracy is significantly affected by equipment and operating techniques. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this utility model proposes a pipe positioning and drilling device, which can replace the original manual positioning method for pipe drilling. It has the advantages of accurate positioning, simple operation, and diverse drilling capabilities, which greatly improves production efficiency.

[0005] To achieve the above objectives, the pipe positioning and drilling device of this utility model includes a base plate, a fixed base on the base plate for supporting the pipe to be processed, a lead screw positioning mechanism parallel to the fixed base on the base plate, a drilling mechanism that can move along its length on the lead screw positioning mechanism, and an electric drill assembly on the drilling mechanism, with the drill bit end of the electric drill assembly facing downward.

[0006] Furthermore, the top of the fixed base is provided with a support track extending along its length, and several fixed supports are slidably connected in the support track. The fixed support is a C-shaped semi-frame structure, and the two ends of the fixed support are respectively provided with locking bolts for locking the pipe to be processed.

[0007] Furthermore, the lead screw positioning mechanism includes a lead screw and a lead screw positioning block. The lead screw positioning block is provided with a lead screw nut, and the lead screw positioning block and the lead screw form a lead screw pair through the lead screw nut. The two ends of the lead screw are respectively provided with lead screw transmission bases, and the two lead screw transmission bases are respectively provided with bearing seats. The two ends of the lead screw are respectively rotatably connected to the bearing seats, and the lead screw can rotate along its own axis. One end of the lead screw extends outward through the bearing seat and is connected to a manual turntable. A guide rod is also connected between the two lead screw transmission bases. The guide rod passes through the lead screw positioning block, and the lead screw positioning block can slide along the guide rod.

[0008] Furthermore, the drilling mechanism includes a vertical rod connected to the lead screw positioning block, the vertical rod being arranged in a vertical direction, a vertical sliding seat being provided on the vertical rod, a locking clamp being provided on the side of the vertical sliding seat, the vertical sliding seat being connected to the vertical rod through the locking clamp, and the electric drill assembly including an electric drill guide rod, the electric drill guide rod being slidably connected to the vertical sliding seat and being able to slide in a vertical direction, an electric drill support plate being provided at the bottom of the electric drill guide rod, an electric drill body being provided on the electric drill support plate, and the drill bit of the electric drill body being set downward.

[0009] Furthermore, a drive block is provided in the middle of the electric drill guide rod, and a drive handle is rotatably connected to the vertical sliding seat. The middle of the drive handle is provided with a waist-shaped groove along its length, and a bolt assembly connected to the drive block passes through the waist-shaped groove.

[0010] Furthermore, the vertical sliding seat has arc edges extending away from the locking clamp on both sides in the longitudinal direction.

The distance is displayed digitally instead of the tape measure for manual measurement and marking. The reading is simple and convenient, the hole position is accurately located, and the processing error is reduced. Attached Figure Description

[0021] The technical solution of this utility model will be more clearly and completely explained below with reference to the accompanying drawings and through the description of the preferred embodiments of this utility model.

[0022] like Figure 1 As shown, the preferred embodiment of the pipe positioning and drilling device of this utility model includes a base plate, on which a fixed base is provided.

A sliding adjustment mechanism is provided on the base plate 1 for adjusting the distance between the lead screw positioning mechanism and the fixed base 2. The straight line of movement of the sliding adjustment mechanism is defined as the Y-axis.

[0023] like Figure 2 and Figure 3As shown, the top of the fixed base 2 is provided with a support rail 21 extending along its length. Several fixed supports 22 are slidably connected in the support rail 21. The fixed supports 22 are U-shaped semi-frame structures, and both ends of the fixed supports 22 are provided with locking bolts for locking the pipe 8 to be processed. The fixed supports 22 can slide to a suitable position in the support rail 21 according to the different lengths of the pipe 8, with the starting end of the pipe 8 aligned with the starting end of the fixed base 2.

[0024] like Figure 2 and Figure 3 As shown, the lead screw positioning mechanism includes a lead screw 31 and a lead screw positioning block 32. A lead screw nut is mounted on the lead screw positioning block 32, forming a lead screw pair with the lead screw 31 via the lead screw nut. Lead screw drive bases 33 are located at both ends of the lead screw 31, and bearing seats are mounted on both sides of the lead screw drive bases 33. Both ends of the lead screw 31 are rotatably connected to the bearing seats, allowing the lead screw 31 to rotate along its own axis. One end of the lead screw 31 extends outward through the bearing seat and is connected to a manual turntable 34. A guide rod 35 is also connected between the two lead screw drive bases 33, passing through the lead screw positioning block 32, allowing the lead screw positioning block 32 to slide along the guide rod 35.

[0025] like Figure 2 and Figure 3 As shown, the length counting mechanism includes a counting scale 71 with graduations. The starting end of the counting scale 71 is aligned with the starting end of the fixed base 2. An electronic digital display 72 is slidably connected to the counting scale 71 and is connected to the lead screw positioning block 32. When the lead screw positioning block 32 is moved, the electronic digital display 72 displays the distance between the lead screw positioning block 32 and the counting scale 71 on the X-axis.

[0026] like Figure 2 and Figure 3 As shown, the drilling mechanism includes a vertical rod 41 connected to the lead screw positioning block 32. The vertical rod 41 is arranged vertically, and a support block and a corresponding slide rail can be provided at the bottom of the vertical rod 41 for support. A vertical sliding seat 42 is provided on the vertical rod 41, and a locking clamp 43 is provided on the side of the vertical sliding seat 42. The vertical sliding seat 42 is connected to the vertical rod 41 through the locking clamp 43. The electric drill assembly includes an electric drill guide rod 5135, which is slidably connected to the vertical sliding seat 42 and can slide in the vertical direction. The vertical sliding seat 42 has arc edges extending away from the locking clamp 43 on both sides in the longitudinal direction. The two arc edges are symmetrical, and the cross section of the arc edges in the horizontal direction is C-shaped. Sliding wheels 44 are provided on the inner side of the vertical sliding seat 42 and the inner side of the arc edges, respectively. The sliding wheels 44 abut against the electric drill guide rod 5135.

[0027] like Figure 2 and Figure 3As shown, the bottom of the drill guide rod 5135 is provided with a drill support plate 52, and the drill body 53 is provided on the drill support plate 52, with the drill bit of the drill body 53 facing downwards. A drive block 54 is provided in the middle of the drill guide rod 5135, and a drive handle 55 is rotatably connected to the vertical sliding seat 42. The drive handle 55 has a waist-shaped groove 56 along its length in the middle, and a bolt assembly connected to the drive block 54 passes through the waist-shaped groove 56. Pressing down the drive handle 55 will press the drill bit down along the Z-axis to drill a hole in the pipe 8.

[0028] like Figure 2 and Figure 3 As shown, the sliding adjustment mechanism includes slide mechanisms located at both ends of the lead screw positioning mechanism along its length. The two slide mechanisms have identical structures. Each slide mechanism includes a pair of slide bases 61 mounted on the base plate 1. A pair of slide connecting rods 62 connects the two slide bases 61. A slider 63 is slidably connected to each slide connecting rod 62. The slider 63 is equipped with a quick-locking device for fixing it to the slide connecting rod 62. Lead screw drive bases 33 are respectively mounted on the sliders 63 on both sides. A counting scale 71 is also fixed to the slider 63 and moves accordingly.

[0029] Specific implementation process: First, fix the pipe 8 and place the starting end of the drilling on the fixed base 2 at the starting point. The starting end of the fixed base 2 corresponds to the "0" point on the counting scale 71. Adjust the fixed bracket 22 to a suitable position according to the length of the pipe 8 and then tighten the screws. Then, drill the hole. Before drilling, operate the manual turntable 34 to adjust the drill bit of the electric drill body 53 to the digital display distance set to "0". The lead screw controls the position of the drill bit to achieve precise control of the hole spacing. According to the digital display distance, move the drill bit to the required drilling position. With the center of the drill bit as the reference point "0", turn on the power switch of the electric drill body 53 and press the Z-axis drive handle 55 to drill. The drilling depth is controlled by pressing the drive handle 55.

[0030] When drilling a conventional center hole in pipe 8, the position of the drill bit on the "Y" axis does not need to be changed (the drill bit is conventionally set at the center of the fixed base 2). For special non-center hole positions, adjustment is made on the sliding adjustment mechanism of the "Y" axis. If pipe 8 is too long to be drilled beyond the fixed base 2, the drilling point of pipe 8 can be adjusted to the starting point of the counting process, the fixed bracket 22 can be moved to re-fix pipe 8, and the drill bit can be adjusted to accommodate pipes of different lengths. The above specific embodiments are merely descriptions of preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Various modifications, substitutions, and improvements made by those skilled in the art to the technical solutions of this utility model based on the text description and drawings provided herein without departing from the design concept and spirit of this utility model should all fall within the scope of protection of this utility model. The scope of protection of this utility model is determined by the claims.
