Description

Technical Field

[0001] This utility model relates to the technical field of aluminum product processing equipment, and in particular to a deburring fixture for aluminum shells. Background Technology

[0002] During the production and processing of aluminum shells, burrs easily form at the four corners. These burrs not only affect the appearance quality of the aluminum shell but may also pose safety hazards during subsequent assembly and use, potentially injuring operators or damaging other mating components. Currently, the most common method for removing burrs from the four corners of aluminum shells is manual sanding with handheld sandpaper. Workers pick up the aluminum shell and smoothly sand one end across the edge with sandpaper. This method makes it difficult to ensure that every corner is thoroughly sanded, resulting in a high percentage of burrs remaining. This method is not only inefficient and requires high worker skill, but also consumes a large amount of sandpaper, has poor burr removal results, and produces uneven sanding, making it difficult to guarantee the processing accuracy of the four corners of the aluminum shell. It also increases the labor intensity of the operators. Therefore, a specialized tooling is needed to achieve efficient and uniform removal of burrs from the four corners of aluminum shells. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model proposes a deburring fixture for aluminum shells.

[0004] This utility model proposes a deburring fixture for aluminum shells, comprising a cuboid frame. A crossbeam is connected between the middle of the lower rectangular frames of the cuboid frame. A positioning bolt is installed at the top of the midpoint of the crossbeam. Two sets of positioning pins are installed at the top of each side of the upper rectangular frame of the cuboid frame. Each set of positioning pins is connected to the positioning bolt by a rubber band. There are eight rubber bands in total, symmetrically distributed. A plastic plate is obliquely installed on every two sets of symmetrical rubber bands. There are four plastic plates in total, all of the same height. Sandpaper can be detachably installed on each set of plastic plates. The four sets of sandpaper are used to polish the four corners of the aluminum shell.

[0005] Preferably, all four sets of plastic plates are inclined relative to the upper rectangular frame side of the cuboid frame, with an inclination angle of 45°.

[0006] Preferably, a limiting beam is fixedly installed between the middle parts of the upper rectangular frame of the cuboid frame. The limiting beam is made of metal and is distributed perpendicularly to the upper rectangular frame. The limiting beam is located between the upper rectangular frame and the plastic plate and is used to limit the downward stroke of the aluminum shell. The setting of the limiting beam can prevent the operator from operating too hard and avoid the aluminum shell from being worn at the corners due to excessive downward pressure, thus playing a role in protecting the aluminum shell.

[0007] Preferably, a sponge pad with a thickness of 5-10mm is glued to the top of the limiting beam. The sponge pad on the top of the limiting beam further enhances the cushioning effect, reduces the hard collision between the aluminum shell and the limiting beam, and provides better protection for the aluminum shell.

[0008] Preferably, the sandpaper is fixed to the plastic plate by metal clips, with 2-4 metal clips corresponding to each piece of sandpaper. The metal clips are spaced apart along the length of the plastic plate. The sandpaper is fixed to the plastic plate by the metal clips, which facilitates the removal and replacement of the sandpaper. When the sandpaper is worn out, it can be replaced with new sandpaper in time to ensure the deburring effect.

[0009] Preferably, the two ends of the rubber band are respectively sleeved on the positioning pin and the positioning bolt. The outer walls of the positioning pin and the positioning bolt are provided with annular grooves to prevent the rubber band from slipping off. The annular grooves on the outer walls of the positioning pin and the positioning bolt can effectively prevent the rubber band from slipping off, ensuring that the rubber band is always in the correct working position and ensuring the normal operation of the tooling.

[0010] Preferably, the rubber band has a diameter of 3-5 mm and can maintain its elasticity when its stretched length is 1.5-2 times its original length.

[0011] This invention proposes an aluminum shell deburring fixture, in which the four corners of the aluminum shell respectively contact sandpaper on four plastic plates. The operator moves the aluminum shell back and forth, using the elasticity of rubber bands to keep the sandpaper in contact with the four corners of the aluminum shell, removing burrs through friction. By simultaneously polishing the four corners of the aluminum shell with four sets of sandpaper, the deburring efficiency is greatly improved compared to traditional manual polishing one by one, which can meet the needs of mass production. The operation is simple and convenient, improving the efficiency and effect of deburring. The four sets of plastic plates are tilted at an angle of 45°, which can better match the four corners of the aluminum shell, ensuring full contact between the sandpaper and the four corners of the aluminum shell, improving the polishing accuracy. The technical requirements for workers are not very high, and the sandpaper consumption is reduced from 2 sheets / hour to 0.5 sheets / hour, a reduction of 75%.

[0012] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] like Figures 1-4 The diagram shows a deburring fixture for aluminum shells. The fixture includes a cuboid frame 1. A crossbeam 101 connects the middle of the lower rectangular frame of the cuboid frame 1. A positioning bolt 102 is installed at the top of the midpoint of the crossbeam 101. Two sets of positioning pins 103 are installed at the top of each side of the upper rectangular frame of the cuboid frame 1. Each set of positioning pins 103 is connected to the positioning bolt 102 by a rubber band 2. There are eight rubber bands 2 in total, symmetrically distributed. A plastic plate 3 is obliquely installed on every two sets of symmetrical rubber bands 2. There are four plastic plates 3 in total, all at the same height. All four sets of plastic plates 3 are obliquely positioned relative to the side of the upper rectangular frame of the cuboid frame 1 at an angle of 45°.

[0020] Each set of plastic plates 3 can be detachably mounted with sandpaper 301. The four sets of sandpaper 301 are used to polish the four corners of the aluminum shell. The sandpaper 301 is fixed to the plastic plate 3 by metal clips. Each sandpaper 301 is equipped with 2-4 metal clips, and the metal clips are spaced apart along the length of the plastic plate 3.

[0021] A limiting beam 4 is fixedly installed between the middle sections of the upper rectangular frame of the cuboid frame 1. The limiting beam 4 is made of metal and is perpendicularly intersecting the upper rectangular frame. The limiting beam 4 is located between the upper rectangular frame and the plastic plate 3 and is used to limit the downward pressure stroke of the aluminum shell. A sponge pad 401 with a thickness of 5-10mm is glued to the top of the limiting beam 4.

[0022] The two ends of the elastic band 2 are respectively sleeved on the positioning nail 103 and the positioning bolt 102, and the outer walls of the positioning nail 103 and the positioning bolt 102 are provided with annular grooves. The diameter of the elastic band 2 is 3-5mm, and it can still maintain its elasticity when its stretched length is 1.5-2 times its original length.

[0023] In use, place the aluminum shell on four plastic plates 3, so that the four corners of the aluminum shell are in contact with the sandpaper 301 on the four plastic plates 3. The operator moves the aluminum shell up and down. Because the rubber band 2 is elastic, it will keep the plastic plates 3 in contact with the four corners of the aluminum shell. The burrs are removed by the friction between the sandpaper 301 and the four corners of the aluminum shell.

[0024] The limiting beam 4 can limit the downward stroke of the aluminum shell, prevent the employee from operating too forcefully, and avoid the corner wear caused by excessive downward pressure on the aluminum shell. The sponge pad 401 on the top of the limiting beam 4 further reduces the collision and impact between the aluminum shell and the limiting beam 4, and prevents the corner wear of the aluminum shell caused by excessive downward pressure on the employee.

[0025] The technical requirements for workers are not very high; the consumption of 301 sandpaper has been reduced from 2 sheets / hour to 0.5 sheets / hour, a reduction of 75% in the consumption of 301 sandpaper.
