Description

Technical Field

[0001] The utility model belongs to the technical field, and specifically relates to a bidirectional drilling device. Background Art

[0002] For some hollow tube components, it is often necessary to drill holes in the tube wall and use screws, connecting shafts, etc. to assemble and connect with other components. In this case, it is necessary to drill holes in the hollow tube components, and the holes are often processed by drilling or stamping. The current drilling method is for workers to support the hollow components and then process them. Commonly used hollow components such as hollow tubes include round tubes, square tubes or waist-shaped tubes. During the support process, the drilling is often offset due to unstable grip. In addition, when drilling, since the drill bit has downward pressure, it is very easy for hollow tubes with thinner walls to have depressions at the drilling position. Especially when the hollow end is perforated, a depression will appear on the edge of the upper hole, and the edge of the lower hole will bulge outward. Such deformation will make the hollow tube difficult to assemble and install. Summary of the Invention

[0016] In the description of this application, it should be understood that the terms "upper" and "lower" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on this application.

[0017] See Figure 1-3 As shown, the present application discloses a bidirectional drilling device, including a driving assembly 10, a drilling assembly 20 and a supporting and positioning assembly 30. The driving assembly 10 has two output ends that can move toward or away from each other, and a drilling assembly 20 is fixed on each output end; specifically, the driving assembly 10 includes a servo motor 12, a screw rod 13 and two nut pairs 15, the two nut pairs 15 have opposite thread rotation directions, and each nut pair 15 is fixedly connected to a slider 14. Then, when the servo motor 12 drives the screw rod 13 to rotate, it can drive the slider 14 to move toward or away from each other. Of course, considering the smooth sliding of the slider 14 and reducing the sliding resistance, a slide rail 16 is also provided in this embodiment, and the slider 14 is connected and installed through the slider and the slide rail 16; the drilling assembly 20 is fixed on the slider 14, and then when the slider 14 moves toward or away from each other, it drives the drilling assembly 20 to move toward or away from each other. The drilling assembly 20 includes a drilling motor 21 and a motor base 22. The drilling motor 21 is provided with a drill bit 24. The drilling motor 21 is fixed to the motor base 22, and the motor base 22 is fixedly connected to the slider 14. In addition, to ensure the smooth sliding of the drilling motor 21 and reduce sliding resistance, a slide rail 23 is provided between the motor base 22 and the machine base 11. The motor base 22 is connected to the slide rail 23 via the slider, thereby achieving smooth sliding of the motor base 22.

[0018] In addition, in this embodiment, the support and positioning assembly 30 includes a support seat 31, which is located between the two drilling assemblies 20. The drilling ends of the two drilling assemblies 20 are coaxial and both face the support seat 31; a through hole 3111 is provided on the support seat 31, and the axis of the through hole 3111 is perpendicular to the axis of the support seat 31; the parts to be processed are mounted on the support seat 31, and the driving assembly 10 drives the two drilling assemblies 20 to drill the parts to be processed.

The fixed base 32 is fixed to the machine base 11, and the mounting base 312 is detachably fixed to the mounting base 312. Screw holes are provided on the fixed base 32 and the mounting base 312. Screws 3121 pass through the mounting base 312 and are screwed into the screw holes on the fixed base to connect the mounting base 312 to the fixed base 32. Then, by removing the screws 3121, the mounting base 312 can be separated from the fixed base 32 and replaced with a new support base 31. Of course, in order to facilitate the precise positioning of the support seat 31 during installation, a positioning plate 321 is provided on the fixing seat 32, and the mounting seat 312 has a positioning edge, and the positioning edge is aligned with the positioning plane of the positioning plate 321 for positioning. Then, when replacing and installing, the positioning edge is aligned with the positioning plane of the positioning plate 321 to ensure that after installation, the axis of the through hole 3111 on the support seat 31 coincides with the axis of the drill bit, thereby achieving rapid replacement and installation.

[0020] Through the setting of the support seat, the part to be processed is placed on the support section, and the two drilling assemblies are driven by the driving assembly to move toward each other, so that holes are drilled on both side walls of the part to be processed at the same time, thereby improving production efficiency; in addition, since the axis of the drill bit coincides with the axis of the through hole, on the one hand, the hollow tube is supported and positioned by the support section, reducing the force required for workers to support the hollow tube; on the other hand, the support section supports the hollow tube, and during the drilling process, it can effectively suppress the deformation of the hole edge, thereby improving product quality and facilitating assembly.
