Description

Technical Field

[0001] The present invention relates to the field of Bluetooth speaker processing, and in particular to a Bluetooth speaker shell drilling device. Background Art

[0002] A Bluetooth speaker refers to an audio device with a built-in Bluetooth chip that uses Bluetooth connection instead of traditional wire connections. It is convenient and fast to connect to Bluetooth playback devices such as mobile phones, tablets, and laptops. Bluetooth speakers are mainly portable speakers, and their appearance is generally small and portable. Bluetooth speaker technology is gradually being valued and accepted by consumers due to its convenience.

[0003] When processing a cylindrical speaker shell with a sealed setting at one end, it is necessary to drill a hole on its top surface. When drilling, a fixing mechanism is generally set on the outside of the shell to lock and fix it. However, since the outside of the shell is directly exposed to the outside, people can see its outer wall directly later, so the aesthetics of its outer wall is required to be higher. When the fixing device clamps it, its surface is easily scratched, resulting in the need for multiple subsequent processing to treat the damaged surface before it can be used. At the same time, many existing drilling assemblies can only drill a hole in a specified position of the shell, which limits its scope of application. Summary of the Invention

[0022] The technical solution of the present invention will be further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0023] A Bluetooth speaker housing drilling device includes a machine platform 1, wherein a drilling component 3 is fixed above the machine platform 1 through a frame 2, and a fixing component 4 for fixing the housing is provided on the top of the machine platform 1:

[0024] The frame 2 is further provided with a slide 5 driven by a cylinder 6, wherein the slide 5 is provided with an electric push rod 7 for driving a drilling assembly 3, and the drilling assembly 3 includes a drill bit 32 driven by a motor I31. The motor I1 is fixed in a box 33, wherein the box 33 is covered with a protective cylinder 34 that can slide up and down, and the protective cylinder 34 is provided with a corrugated hose 35 connected to the exhaust fan, and the corrugated hose 35 is suspended from the top of the frame 2 by an elastic rope;

[0025] A circular hole 8 is provided on the top wall of the machine 1, wherein a cylinder 19 with a top seal is provided in the circular hole 8, and a circle of arc-shaped grooves 9 are provided on the outer wall of the cylinder 19 and the side wall of the circular hole 8, wherein a plurality of balls 10 are arranged in parallel in two groups of arc-shaped grooves 9;

[0026] The fixing assembly 4 includes a pillar 41 arranged on the top of the cylinder 19, wherein a circular seat 42 is provided at the top of the pillar 41, and arc-shaped plates 43 are provided on both sides of the pillar 41 below the circular seat 42, and a vertical rod 44 is provided on the inner side of the arc-shaped plate 43, which passes through a sliding opening 45 on the top wall of the cylinder 19, wherein positive and negative screw rods 46 passing through the bottom ends of the corresponding two groups of vertical rods 44 are provided in the opening of the cylinder 19, and the positive and negative screw rods 46 are driven by a motor II47, and a boss 11 for fixing the positive and negative screw rods 46 is provided on the inner top wall of the cylinder 19 outside the sliding opening 45, wherein the boss 11 is provided with a rolling bearing sleeved on the positive and negative screw rods 46, and the motor II47 is arranged in the opening of the cylinder 19.

[0027] In this embodiment, a gear ring 12 is mounted on a cylinder 19 above the machine 1. A gear 13 meshes with the gear ring 12, and the gear 13 is driven by a motor III 14 within the machine 1. Motor III 14 drives the gear 13, which in turn rotates the gear ring 12. This in turn drives the arcuate groove 9 on the cylinder 19 to slide over the ball bearing 10, which in turn drives the fixed assembly 4 to rotate.

[0028] In this embodiment, the size of the vertical rod 44 is adapted to the width of the sliding opening 45 , wherein the top of the vertical rod 44 is fixedly connected to the inner arc wall of the arc plate 43 through multiple sets of cross rods, and the vertical rod 44 is also provided with screw holes for screwing with the forward and reverse screw rods 46 .

[0029] In this embodiment, a slide rail 15 is horizontally arranged on the top of the frame 2, wherein a slide groove is arranged on the back of the slide 5 to match the slide rail 15. The slide rail 15 fixes the slide groove, and the slide 5 is fixed above the frame 2, so that the cylinder 6 can drive the slide 5 to drive the slide groove to slide on the slide rail 15.

[0030] like Figure 1 、 3 As shown, an extension plate 16 is provided on the top of the box body 33, wherein a slide rod 17 passing through the extension plate 16 is provided on the side wall of the protective tube 34, and a protrusion is provided on the top of the slide rod 17, and a spring 18 is provided on the outer sleeve of the slide rod 17 below the extension plate 16.

[0031] The working principle of the present invention is as follows: the cylinder 19 is suspended on the machine table 1 by means of the ball bearing 10 pressing against the arc groove 9. When in use, the shell with a sealed top is buckled on the circular seat 42 and the fixed component 4, wherein the motor II 47 drives the forward and reverse screw rods 46 to rotate in the screw holes on the vertical rods 44, thereby driving the vertical rods 44 to slide in the sliding openings 45 while expanding the distance between the two groups of vertical rods 44, so that the vertical rods 44 push the arc plates 43 to move outward and contact the inner arc wall of the shell, thereby locking the shell to the fixed component 4 through the two groups of outward moving arc plates 43;

[0032] The electric push rod 7 drives the drilling assembly 3 to move downward, so that the protective cylinder 34 first contacts the top wall of the shell. As the drilling assembly 3 continues to move downward, the shell will squeeze the protective cylinder 34 to drive the slide rod 17 to move upward in the hole on the extension plate 16, and at the same time compress the spring 18. When the drill bit 32 contacts the top wall of the shell, it is driven by the motor 131 to perform drilling. At this time, the protective cylinder 34 prevents the debris obtained by drilling from overflowing. At the same time, the exhaust fan and the corrugated hose 35 are used to extract the debris obtained by drilling to improve the working environment.

[0033] When it is necessary to drill holes in different areas of the top of the shell, the slide 5 can be driven by the cylinder 6 to drive the electric push rod 7 and the drilling assembly 3 to move left and right, so that it covers the straight line formed between the left and right ends of the shell top wall, and then drills the shell top wall at any position on the straight line. At the same time, the motor III14 drives the arc groove 9 on the cylinder 19 to rotate on the ball 10 through the gear 13 and the gear ring 12, and the cylinder 19 also drives the shell on the fixed assembly 4 to rotate together. When the required drilling position is moved to the bottom of the drill bit 32, it stops rotating, so as to achieve the above-mentioned cooperation, so that the drilling assembly 3 can drill holes in different areas on the top surface of the rotating shell.

[0034] The present invention has been described in detail above, but the contents described are only preferred embodiments of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
