Description

Technical Field

[0001] The utility model relates to a device for deburring the inner wall of a square tube of a display bracket. Background Art

[0002] In modern life and work, monitors, as an indispensable visual display device, have long penetrated into every aspect of our daily lives. Whether it is leisure, entertainment or work guidance, it is inseparable from its presence. Precisely because of its ubiquitous application scenarios, the monitor stand used with it is particularly important. The monitor stand is formed by connecting multiple components. Common components include square tubes, round tubes, flat tubes and other pipes. Through holes are processed on the pipes for connection with other components. Burrs will be formed on the inner wall of the pipe during the punching process of the through holes. If they are not polished and removed, the burrs and debris will easily enter the screw groove of the bolt when the bolt is subsequently installed, affecting the stability of the connection. Because the burrs are on the inner wall of the pipe, the existing deburring device is not easy to extend, and manual polishing is mostly used, which has low deburring efficiency.

[0019] like Figure 1 As shown, the utility model describes a deburring device for the inner wall of a square tube of a display stand, comprising a base 1, a grinding block 3 symmetrically arranged on the base 1, a blade portion 31 corresponding to the upper and lower sides of the grinding block 3 facing each other, a grinding surface 32 arranged on the upper and lower surfaces of the grinding block 3, a side opposite to the grinding block 3 connected to a side push cylinder 4, an upper pressing block 5 is arranged above the middle of the base 1, the upper part of the upper pressing block 5 is connected to a lifting plate 8 through an elastic telescopic rod 7, a limiting groove 51 is machined at the lower part of the upper pressing block 5 along the length direction, a limiting rod 6 is vertically installed in the middle of the limiting groove 51, the depth of the limiting groove 51 is less than the height of the square tube 2, the width of the limiting groove 51 matches the width of the square tube 2, and the lower part of the limiting groove 51 is machined to form a guide inclined surface 52 (see Figure 2 ), the length of the limiting rod 6 is less than the height of the square tube 2, the limiting rod 6 and the upper pressure block 5 are connected by a thread, the upper part of the lifting plate 8 is connected to the pushing cylinder 11, and the pushing cylinder 11 is installed in the middle of the upper fixed seat 10, and the lifting plate 8 forms a sliding fit with the upper fixed seat 10 through the guide rod 9;

[0020] During operation, the square tube 2 is placed horizontally in the middle of the base 1, the upper pressure block 5 moves downward to press the square tube 2, the limiting rod 6 cooperates to extend into the process hole 22 in the middle of the square tube 2, and the grinding blocks 3 on both sides simultaneously extend into the two ends of the square tube 2 and grind the inner cavity wall.

[0021] The device uses the upper pressure block and the limit rod to press the square tube and form a center positioning, so that the two grinding blocks can be inserted into the inner cavity of the square tube at the same time to grind the burrs on the inner cavity wall formed by punching the through hole. The positioning is accurate, the force is stable and uniform, damage to the square tube is avoided, and the processing efficiency is high.

[0022] In order to facilitate the understanding of the present invention, the following description will be given in conjunction with the accompanying drawings.

[0023] like Figure 4-6 As shown, through holes 21 are machined on the upper and lower side walls near both ends of the square tube 2 for connecting with other components. After the through holes 21 are stamped, burrs will be formed on the inner wall of the square tube 2. The solution in this embodiment is mainly used to grind the burrs on the inner end surface of the through holes 21. To facilitate positioning, a process hole 22 is first machined on the upper side wall of the middle part of the square tube 2.

[0024] During operation, the square tube is placed horizontally in the middle of the base, with the process hole in the middle of the square tube facing upward. The pushing cylinder drives the lifting plate to move downward as a whole, and the upper pressure block presses the square tube after the lifting plate moves downward. The elastic telescopic rod forms an elastic contraction accordingly, and the upper part of the square tube extends into the limit groove at the lower part of the upper pressure block, and the limit rod in the middle of the limit groove cooperates to extend into the process hole in the middle of the square tube; after the positioning is completed, the side push cylinder drives the grinding block to extend into both ends of the square tube at the same time, and the blade at the end of the grinding block first cuts the inner end face of the through hole, and then uses the grinding surface to grind the inner cavity wall; after the grinding is completed, the grinding block exits the inner cavity of the square tube, and the pushing cylinder drives the lifting plate and the upper pressure block to move upward and reset, and the square tube can be taken out.
