Detailed Implementation

[0027] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0028] See Figure 1 and Figure 5 As shown, an embodiment of the present invention provides a drilling fixture for a photovoltaic support tube, comprising:

[0029] Positioning plate 10, on which a rotating shaft 150 is rotatably mounted;

[0030] A drilling guide rail 80 is connected to a rotating shaft 150, and an angle locking mechanism is provided between the drilling guide rail 80 and the positioning plate 10.

[0031] The round pipe clamp 20 is used to clamp onto the round pipe, and the round pipe clamp 20 is fixedly connected to the positioning plate 10.

[0032] Mounting bracket 40 is used to mount drilling tools. Mounting bracket 40 is movably mounted on drilling guide rail 80 so that mounting bracket 40 can move along drilling guide rail 80 to approach and move away from round pipe clamp 20.

[0033] This embodiment provides a drilling fixture for a photovoltaic support tube, comprising a positioning plate 10, a drilling guide rail 80, a tube clamp 20, and a mounting bracket 40. A rotating shaft 150 is mounted on the positioning plate 10, and the drilling guide rail 80 is connected to the rotating shaft. During operation, the drilling tool is fixed to the mounting bracket 40, and then the rotating shaft 150 is driven to rotate to a set position. An angle locking mechanism locks the mounting bracket 40 and the positioning plate 10 in place, preventing the drilling guide rail 80 from moving during drilling. Then, the drilling is completed by driving... The mounting bracket 40 moves along the drilling guide rail 80, allowing the drill bit of the drilling tool to approach the round pipe from the side and drill a hole in the round pipe. After drilling is completed, the drill bit of the drilling tool is driven away from the round pipe. This eliminates the need to hold the drilling tool while drilling, thus improving drilling efficiency and accuracy. In addition, the drill bit of the drilling tool can be adjusted by adjusting the drilling guide rail 80 to achieve oblique drilling. Furthermore, the drilling fixture in this embodiment is positioned on the round pipe by the round pipe clamp 20, making the positioning operation more convenient and the positioning more stable.

[0034] Specifically, in this embodiment, the positioning plate 10 has a rotating mounting hole 103 at its center, and the rotating shaft 150 is rotatably disposed in the rotating mounting hole 103.

[0035] In addition, in this embodiment, there are two round pipe clamps 20. The two round pipe clamps 20 are arranged coaxially and side by side, and the two round pipe clamps 20 are connected by a fixed bracket 140. The positioning plate 10 is fixed to the fixed bracket 140 by bolts. The fixed bracket 140 is located on the top of the round pipe clamp 20. The inner side of the round pipe clamp 20 has an arc surface, which matches the circumferential surface of the round pipe.

[0036] There are two mounting brackets 40, which are symmetrically arranged on the drilling guide rail 80. When the round pipe clamp 20 is installed on the round pipe, the two mounting brackets 40 are located on both sides of the round pipe clamp 20. Each mounting bracket 40 can be fixed with a drilling tool, which can drill holes in the round pipe from both sides at the same time.

[0037] In this embodiment, the mounting bracket 40 extends downward and is located between the two round tube clamps 20.

[0038] In a further embodiment of this invention, the drilling fixture for the photovoltaic support tube further includes a feeding mechanism 50, which is connected to the mounting bracket 40 and is used to drive the mounting bracket 40 to move along the drilling guide rail 80.

[0039] In a further embodiment of this invention, the feeding mechanism 50 includes a rotating rod 501 and a connecting rod 502. One end of the connecting rod 502 is hinged to the end of the rotating rod 501, and the other end of the connecting rod 502 is hinged to the mounting bracket 40. The rotation center of the rotating rod 501 is coaxially arranged with the rotating shaft 150.

[0040] The feeding mechanism 50 in this embodiment specifically includes a rotating rod 501 and two connecting rods 502. The rotating rod 501 is hinged in the middle on the fixed bracket 140. One end of each of the two connecting rods 502 is hinged to both ends of the rotating rod 501, and the other end of each of the two connecting rods 502 is hinged to two mounting brackets 40.

[0041] It can drive the two mounting brackets 40 to move along the drilling guide rail 80 by driving the rotating rod 501.

[0042] In a further embodiment of this invention, rotating wheels 70 are provided on the mounting bracket 40 and on both sides of the drilling guide rail 80. The rotating wheels 70 are provided with wheel grooves, and both sides of the drilling guide rail 80 are engaged in the wheel grooves.

[0043] In this embodiment, the rotating wheel 70 and the mounting bracket 40 connected to the rotating wheel 70 are mounted on the drilling guide rail 80 through the groove on the rotating wheel 70. This not only allows the drilling angle to be adjusted by rotating the drilling guide rail 80 to achieve drilling at different angles and positions, but also allows the mounting bracket 40 to move along the drilling guide rail 80 by rotating the rotating wheel 70.

[0044] In a further embodiment of this invention, the circular tube clamp 20 includes a fixed clamp 201 and a movable clamp 202. The inner sides of the fixed clamp 201 and the movable clamp 202 have arc-shaped contact surfaces corresponding to the circular tube. The upper end of the movable clamp 202 is hinged to the fixed clamp 201. A locking mechanism 30 is provided on the movable clamp 202. The locking mechanism 30 is used to drive the movable clamp 202 so that the movable clamp 202 is clamped and positioned on the circular tube.

[0045] In this embodiment, the movable clamp 202 is tightened onto the round pipe to lock and position the round pipe clamp 20 onto the round pipe. This allows for the installation and removal of the round pipe clamp 20. Specifically, the round pipe clamp 20 can be locked by the locking mechanism 30. After drilling is completed, the locking mechanism 30 can be opened to allow the round pipe clamp 20 to move along the length of the round pipe to the next drilling position, making the operation more convenient.

[0046] In a further embodiment of this invention, the movable clamp 202 is provided with an installation rod 160, and the locking mechanism 30 includes a first installation block 301, a second installation block 305, an adjusting screw 304, and an adjusting nut 303. The first installation block 301 is fixed on the fixed clamp 201, and the fixed clamp 201 is provided with a waist-shaped groove 302. The second installation block 305 is provided with a through hole 306, and the installation rod 160 passes through the through hole 306. The upper end of the adjusting screw 304 extends into the waist-shaped groove 302, and the adjusting nut 303 is threadedly connected to the adjusting screw 304.

[0047] In this embodiment, since the adjusting screw 304 extends into the waist-shaped groove 302, it can move in the waist-shaped groove 302. It can move the movable clamp 202 by turning the adjusting nut 303, and thus be clamped on the round tube.

[0048] In a further embodiment of this invention, the positioning plate 10 is provided with a first arc-shaped groove 101, which is coaxial with the rotating shaft 150. The angle locking mechanism includes a locking screw 90 and a locking nut 100. The drilling guide rail 80 is provided with a locking screw 90, which is movably disposed in the first arc-shaped groove 101. The locking nut 100 is threadedly connected to the locking screw 90.

[0049] When the drilling guide 80 rotates, the locking screw 90 can move in the first arc groove 101, and the drilling guide 80 can be locked and positioned by tightening the locking screw 90.

[0050] In a further embodiment of this invention, the positioning plate 10 is also provided with a second arc-shaped groove 102, which is coaxially arranged with the rotating shaft 150. A guide rod 170 is provided on the rotating rod 501, and the guide rod 170 is movably arranged in the second arc-shaped groove 102.

[0051] In this embodiment, when the rotating rod 501 rotates, the guide rod 170 can move along the second arc-shaped groove 102.

[0052] In a further embodiment of this invention, an angle adjustment handle 110 is fixed on the rotating shaft 150.
