Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, specifically relating to a drilling device for processing cylindrical workpieces. Background Technology

[0002] In existing technologies, drilling holes in workpieces is a common processing technique. Traditional drilling processes are mainly used to drill holes on the top and bottom surfaces of workpieces. However, since some cylindrical workpieces are relatively thin, when drilling holes on the side walls, the workpiece is usually placed vertically for drilling. This method requires clamping the cylindrical product during the drilling process. Since cylindrical objects are not easy to clamp, the clamping effect of existing drilling devices is generally poor. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a drilling device for processing cylindrical workpieces, which can effectively keep the workpiece stable during drilling.

[0004] To achieve the objective of this utility model, the technical solution adopted by this utility model is as follows: A drilling device for machining cylindrical workpieces includes a clamping mechanism, a drilling mechanism, and a base for placing the workpiece. The drilling mechanism is positioned facing the base and includes a slide rail and an electric drill. A sliding mechanism that moves axially is mounted on the slide rail, and the electric drill is mounted on the sliding mechanism with the drill bit facing the workpiece. The clamping mechanism includes a support lever and a lifting cylinder. The support lever consists of a support frame and a lever, and the lever is hinged to the top of the support frame. The lifting cylinder is positioned below the end of the lever away from the base, and the lifting rod of the lifting cylinder is hinged to the end of the lever. The other end of the lever is located above the base, is L-shaped facing downwards, and has a pressure plate at its end. A rubber pad is provided on the bottom surface of the pressure plate, and the upper surface of the pressure plate is hinged to the lever.

[0005] The thickness of the rubber pad described in this utility model is more than 3cm.

[0006] The base of this utility model is equipped with a vertical positioning plate.

[0007] Preferably, a horizontal top plate is installed on the top of the positioning plate.

[0008] The base of this utility model has two drilling mechanisms on the same side, two slide rails arranged in a figure-eight shape, and a clamping mechanism disposed between the two slide rails.

[0009] Preferably, the slide rail consists of two parallel I-shaped rails, and both sides of the sliding mechanism are provided with slide grooves that cooperate with the I-shaped rails; an axial screw is provided between the two rails, and the end of the screw away from the base is connected to a rotating motor; a slider is installed at the bottom of the sliding mechanism, and a through threaded hole is provided on the slider, which is movably connected to the screw through the threaded hole.

[0010] The electric drill of this invention includes a drill bit facing the workpiece and a drive motor, and a dust cover is provided on the outside of the drive motor.

[0011] The base of this utility model is provided with a workpiece placement plate.

[0012] The top of the support frame of this utility model is provided with multiple hinge holes for connecting with levers.

[0013] The beneficial effects of this utility model are as follows: 1. The drilling device of this utility model uses a lifting cylinder to push the lever. Due to the short movement distance of the lifting rod and the inherent surplus of the hinge hole, the lateral displacement of the lever end in the horizontal direction can be ignored. It will move upward with the lifting rod, driving the pressure plate at the other end to press the workpiece downward. The lever principle can increase the downward pressure, effectively resist the lateral thrust generated by the electric drill, and can keep the workpiece stable during drilling.

[0014] 2. To resist the lateral thrust generated by the electric drill, using a large downward pressure can easily damage the workpiece. Using a rubber pad with a thickness of 3cm or more provides better cushioning and protection. Attached Figure Description

[0020] To more clearly and in detail illustrate the objective technical solution of this utility model, the present utility model will be further described below through relevant embodiments. The following embodiments are merely illustrative of the implementation methods of this utility model and do not limit the scope of protection of this utility model. Example 1

[0021] like Figure 1 As shown, a drilling device for processing cylindrical workpieces includes a clamping mechanism 1, a drilling mechanism 2, and a base 3 for placing the workpiece. The drilling mechanism 1 is positioned facing the base 3. The drilling mechanism 2 includes a slide rail 21 and an electric drill 22. A sliding mechanism 23 that moves axially is mounted on the slide rail 21. The electric drill 22 is mounted on the sliding mechanism 23, and the drill bit 221 faces the workpiece 4. The clamping mechanism 1 includes a support lever and a lifting cylinder 12. The support lever consists of a support frame 11 and a lever 5. The lever 5 is hinged to the top of the support frame 11. The lifting cylinder 12 is positioned below the end of the lever 5 away from the base 3, and the lifting rod of the lifting cylinder 12 is hinged to the end of the lever 5. The other end of the lever 5 is located above the base 3, is L-shaped and facing downwards, and has a pressure plate 6 at the end. A rubber pad 7 is provided on the bottom surface of the pressure plate 6, and the upper surface of the pressure plate 6 is hinged to the lever 5.

[0022] The workpiece 4 is placed on the base 3. The lifting rod of the lifting cylinder 12 is pushed upward. Due to the short movement distance of the lifting rod and the inherent surplus of the hinge hole, the lateral displacement of the lever 5 end in the horizontal direction can be ignored, and it will move upward together with the lifting rod. Under the action of the lever 5, the pressure plate 6 at the other end descends. The upper surface of the pressure plate 6 is hinged to the lever 5. When the pressure plate 6 contacts the workpiece 4 below, it will adaptively adjust its angle to be flush with the upper surface of the workpiece and stably press the workpiece 4 downward. The sliding mechanism 23 moves along the slide rail 21 towards the workpiece 4, driving the electric drill 22 to move towards the workpiece 4, and the electric drill 22 is turned on to start drilling. After drilling is completed, the sliding mechanism 23 returns to its original position, the lifting rod of the lifting cylinder 12 descends, driving the pressure plate 6 to rise, and the workpiece 4 is removed. Example 2

[0023] This embodiment is based on embodiment 1: like Figure 2As shown, the rubber pad 7 is more than 3 cm thick. When drilling, the electric drill 22 generates a large thrust, requiring corresponding pressure to be applied to the workpiece 4 to prevent displacement. Excessive downward pressure can easily damage the workpiece; therefore, using a rubber pad 7 with a thickness of more than 3 cm provides better cushioning and protection.

[0024] A vertical positioning plate 8 is installed on the base 3. Placing the workpiece 4 on the positioning plate 8 allows for better positioning. Example 3

[0025] This embodiment is based on embodiment 1: like Figure 2 As shown, the top of the support frame 11 is provided with multiple hinge holes 111 for connecting to the lever 5. This facilitates adjustment of the installation position of the lever 5 to accommodate workpieces of different heights. Example 4

[0026] This embodiment is based on embodiment 2: like Figure 3 As shown, two drilling mechanisms 2 are provided on the same side of the base 3, and the two slide rails 21 are arranged in a figure-eight shape. The clamping mechanism 1 is located between the two slide rails 21. This facilitates drilling adjacent double holes.

[0027] The top of the positioning plate 3 is equipped with a horizontal top plate 81, which is suitable for workpieces with protruding structures below.

[0028] The base 3 is provided with a workpiece placement plate 31, which facilitates the adjustment of the height of the workpiece 4. Example 5

[0029] This embodiment is based on embodiment 4: like Figure 4 As shown, the slide rail 21 consists of two parallel I-shaped tracks. Both sides of the sliding mechanism 23 are provided with slide grooves 231 that cooperate with the I-shaped tracks. An axial screw 10 is provided between the two tracks. The end of the screw 10 away from the base is connected to a rotating motor 9. A slider 232 is installed at the bottom of the sliding mechanism 23. The slider 232 is provided with a through threaded hole and is movably connected to the screw 10 through the threaded hole.

[0030] The rotating motor 9 drives the screw 10 to rotate, and the slide rails on both sides of the slider 232 cannot rotate. Instead, the slider moves along the direction of the screw 10, thereby driving the sliding mechanism to move along the slide rails. Example 6

[0031] This embodiment is based on embodiment 5: like Figure 4As shown, the electric drill 22 includes a drill bit 221 facing the workpiece and a drive motor 222, and a dust cover is provided on the outside of the drive motor 222.

[0032] The lifting cylinder, electric drill, and drive motor used in this invention are all existing equipment.

[0033] Connection methods not mentioned in this utility model include welding, snap-fitting, riveting, threaded connection, or bonding.

[0034] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
