Description

Technical Field

[0001] This utility model relates to the field of drilling technology, specifically to a drilling auxiliary tooling for countersinking aluminum profiles. Background Technology

[0002] Aluminum profiles are aluminum materials with specific cross-sectional shapes obtained through processes such as hot melting and extrusion. They are made primarily of aluminum alloys and are characterized by being lightweight, high-strength, corrosion-resistant, and easy to process.

[0003] When processing aluminum profiles, it is sometimes necessary to countersink holes at specific locations on the aluminum profile. To ensure the accuracy of the drilling position, a ruler is usually used to measure the drilling position on the aluminum profile and a mark is made at this position with a pen. Then, an auxiliary drilling tool with a drilling guide hole on its outer surface is fixed to the aluminum profile, and its drilling guide hole is aligned with the mark. Finally, the drill bit on the electric drill is aligned with the drilling guide hole and pushed down until it completely penetrates the aluminum profile. The auxiliary drilling tool used to assist in drilling the aluminum profile in this process can be called a drilling auxiliary tooling for countersinking aluminum profiles.

[0004] However, when using this drilling auxiliary tool, it is necessary to first use a ruler to measure the drilling position and mark it with a pen, which is a rather cumbersome operation; therefore, it does not meet the existing needs. In response, we have proposed a drilling auxiliary tool for countersinking aluminum profiles. Utility Model Content

[0005] The purpose of this utility model is to provide a drilling auxiliary tooling for countersinking aluminum profiles, so as to solve the problems mentioned in the background art, which require measuring the drilling position with a ruler and marking the position with a pen when using this drilling auxiliary tooling, which is a relatively cumbersome operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drilling auxiliary tooling for countersunk holes in aluminum profiles, comprising an aluminum profile, a metal shell provided at the front of the aluminum profile, a stepper motor fixedly installed on one side inside the metal shell, the output shaft of the stepper motor connected to a transmission shaft via a coupling, a first bevel gear fixedly sleeved on one side of the outer surface of the transmission shaft, a second bevel gear meshing with each of the four end corners of the outer surface of the first bevel gear, a gear transmission shaft connected to the shaft of the second bevel gear, a threaded rod fixedly connected to one end of the gear transmission shaft, a lifting plate connected to one side of the outer surface of the threaded rod via a thread, and both ends of the lifting plate being slidably connected to the interior of the metal shell;

[0007] A ruler slide rod is fixedly provided on both sides of the rear end face of the lifting plate. A slide plate is slidably connected to one side of the outer surface of the two ruler slide rods fixed to the same rear end face of the lifting plate. A drill guide hole penetrating the slide plate is provided on one side of the outer surface of the slide plate.

[0008] Preferably, a transparent window is provided on both sides of the drill guide hole on the outer surface of the slide plate, and a positioning rod is fixedly provided at the middle position of the upper end face of the transparent window.

[0009] Preferably, one side of the transparent window is provided with a threaded fixing rod connected to the outer surface of the slide plate by a threaded structure, and one end of the threaded fixing rod is fixedly installed with a manual rotation handle.

[0010] Preferably, the stepper motor has a motor control button fixedly mounted on the outer surface of the metal casing in front of it, and the stepper motor and the motor control button are electrically connected.

[0011] Preferably, the outer surface of the scale slide is engraved with graduations, and the surface of the scale slide facing the aluminum profile is in contact with the aluminum profile.

[0012] Preferably, the rear end of the transmission shaft is located inside the metal housing, and the transmission shaft located inside the metal housing is connected to the metal housing by a roller bearing.

[0013] Preferably, the stepper motor is provided with an arc-shaped metal cover plate located on the upper end face of the metal casing, and the metal casing and the arc-shaped metal cover plate are fixed together by screws.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model involves placing an aluminum profile between four sliding plates when the device is needed, ensuring that its front end is in contact with the metal casing. Then, a stepper motor moves the sliding plates and the ruler sliding rod connected to them toward the aluminum profile until the ruler sliding rod is in contact with the aluminum profile. Once in contact, the distance between the drilling guide hole on the outer surface of the sliding plate and the front end of the aluminum profile can be seen through the transparent window on the outer surface of the sliding plate. When drilling is required at a distance of 20 centimeters from the front end of the aluminum profile, the sliding plate is slid directly on the outer surface of the ruler sliding rod, and the positioning rod on the upper end of the fixed transparent window is aligned with the corresponding scale position on the ruler sliding rod to complete the positioning. This technical solution reduces the cumbersome operation of auxiliary tooling. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] The aluminum profile 1 (model QL-4040Q-1.1), stepper motor 3 (model DM542), and threaded rod 8 (model M08) mentioned in this utility model can be obtained from the market or through private customization.

[0023] Please see Figures 1 to 4 An embodiment of this utility model provides a drilling auxiliary tool for countersinking aluminum profiles, including an aluminum profile 1, a metal shell 2 at the front of the aluminum profile 1, a stepper motor 3 fixedly installed on one side inside the metal shell 2, the output shaft of the stepper motor 3 connected to a transmission shaft 4 via a coupling, a first bevel gear 5 fixedly sleeved on one side of the outer surface of the transmission shaft 4, a second bevel gear 6 meshing with each of the four end corners of the outer surface of the first bevel gear 5, a gear transmission shaft 7 connected to the shaft of the second bevel gear 6, a threaded rod 8 fixedly connected to one end of the gear transmission shaft 7, a lifting plate 9 threadedly connected to one side of the outer surface of the threaded rod 8, and both ends of the lifting plate 9 slidingly connected to the interior of the metal shell 2;

[0024] A ruler slide rod 10 is fixedly provided on both sides of the rear end face of the lifting plate 9. A slide plate 11 is slidably connected to one side of the outer surface of the two ruler slide rods 10 fixed to the rear end face of the same lifting plate 9. A drill guide hole 12 is provided on one side of the outer surface of the slide plate 11.

[0025] A transparent window 13 is provided on both sides of the drill guide hole 12, located on the outer surface of the slide plate 11. A positioning rod 14 is fixedly installed at the middle position of the upper end face of the transparent window 13. A motor control button is fixedly installed on the outer surface of the metal shell 2 in front of the stepper motor 3, and the stepper motor 3 is electrically connected to the motor control button. The outer surface of the scale slide 10 is engraved with graduations, and the surface of the scale slide 10 facing the aluminum profile 1 is in contact with the aluminum profile 1. When this device is needed, the aluminum profile 1 is placed between the four slide plates 11, ensuring that... Its front end is attached to the metal casing 2. Then, the stepper motor 3 is started by the motor control button. The stepper motor 3 can drive the transmission shaft 4 connected to it and the first bevel gear 5 fixedly sleeved on the outer surface of the transmission shaft 4 to rotate. The rotating first bevel gear 5 can drive the four second bevel gears 6 meshing with it to rotate together. The rotating second bevel gears 6 can drive the gear transmission shaft 7 connected to the shaft of the second bevel gear 6 and the threaded rod 8 fixed to the gear transmission shaft 7 to rotate together. When the threaded rod 8 rotates... During rotation, the lifting plate 9 connected to it via a threaded structure will move up and down accordingly. Simultaneously, four lifting plates 9 move inward. As the lifting plates 9 move, the ruler slide rod 10 fixed to them and the sliding plate 11 slidably mounted on the outer surface of the ruler slide rod 10 will move together towards the aluminum profile 1. When all the ruler slide rods 10 are in contact with the aluminum profile 1, the stepper motor 3 is turned off. At this point, the position can be determined through the transparent window 13 located on the outer surface of the sliding plate 11 and the positioning rod 14 fixed at the middle position of the upper end face of the transparent window 13. The distance between the drilling guide hole 12 on the outer surface of the slide plate 11 and the front end face of the aluminum profile 1 is specified. When drilling is required at a distance of 20 centimeters from the front end face of the aluminum profile 1, the slide plate 11 is slid directly on the outer surface of the ruler slide rod 10, and the positioning rod 14 on the upper end face of the fixed transparent window 13 is aligned with the 20-centimeter mark on the ruler slide rod 10 to complete the positioning. After that, the operator can align the drill bit on the electric drill with the drilling guide hole 12 and insert it. The above technical solution reduces the cumbersome operation of the auxiliary tooling.

[0026] A threaded fixing rod 15 is provided on one side of the transparent window 13 and is connected to the outer surface of the slide plate 11 by a threaded structure. A manual rotating handle is fixedly installed at one end of the threaded fixing rod 15. When the slide plate 11 is moved to the corresponding position, the threaded fixing rod 15 can be rotated to move the threaded fixing rod 15 toward the ruler slide rod 10, thereby fixing the slide plate 11 in the current position. By fixing the slide plate 11, it can be prevented from sliding during drilling operations.

[0027] The rear end of the transmission shaft 4 is located inside the metal housing 2, and the transmission shaft 4 inside the metal housing 2 is connected to the metal housing 2 by a roller bearing; the roller bearing structure between the transmission shaft 4 and the metal housing 2 can ensure the stability of the rotating transmission shaft 4.

[0028] An arc-shaped metal cover plate is provided above the stepper motor 3 on the upper end face of the metal housing 2, and the metal housing 2 and the arc-shaped metal cover plate are fixed together by screws; the arc-shaped metal cover plate can protect the internal structure of the metal housing 2, and when the internal structure of the metal housing 2 fails, the arc-shaped metal cover plate can be removed to repair its internal structure.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
