Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically a fixture for processing computer casings. Background Technology

[0002] The computer case, also known as a chassis or laptop shell, is an indispensable component of a computer hardware system. It is more than just a "shell"; it serves multiple functions, including structural support, heat dissipation management, electromagnetic shielding, and security protection. The fixture used for computer casing processing is a key piece of equipment in mechanical manufacturing to ensure the accuracy, efficiency and stability of casing processing. This equipment can fix the temperature of the computer casing to be processed on the processing table to ensure that the computer casing does not move when it is being ground, sandblasted or engraved.

[0003] However, some existing computer casing processing fixtures, in order to accommodate computer casings of various sizes, use four cylinders to push four fixing heads to fix the laptop casing. When applying pressure to the thin-walled areas of the casing made of aluminum alloy or magnesium alloy in this way, the casing may be dented and slightly deformed by the fixture. Therefore, it does not meet the current requirements. In response, we have proposed a new type of fixture for computer casing processing. Utility Model Content

[0004] The purpose of this utility model is to provide a fixture for processing computer casings, in order to solve the problems mentioned in the background art. Some existing fixtures for processing computer casings use four cylinders to push four fixing heads to fix the laptop casing in order to adapt to various sizes of computer casings. When pressure is applied to the thin-walled area of ​​the casing made of aluminum alloy or magnesium alloy in this way, the casing may be dented and slightly deformed by the fixture.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixture for processing computer casings, including a fixture table, with a sliding groove at each of the four corners of the upper surface of the fixture table. A hollow metal shell is slidably installed inside the sliding groove. A single-cylinder cylinder is fixedly installed on the lower side inside the hollow metal shell. The piston rod of the single-cylinder cylinder is connected to a push plate. A push sleeve is fixedly provided at the middle position of the upper surface of the push plate. A metal rod is fixed to the upper side inside the hollow metal shell above the push sleeve. A spring is sleeved at the middle position of the outer surface of the metal rod. Both ends of the spring are connected to a chuck that is movably sleeved on the outer surface of the metal rod, and the surface of the chuck facing the push sleeve is a second inclined surface.

[0006] Preferably, both sides of the upper surface of the push plate are first inclined surfaces, and a strip-shaped fixing tooth is provided above the first inclined surface to be slidably connected to the hollow metal shell.

[0007] Preferably, one side of the strip-shaped fixing tooth is provided with a rubber strip fixed to the inner wall of the groove, and the side of the strip-shaped fixing tooth with the tooth head faces the rubber strip.

[0008] Preferably, a return spring is connected to both sides of the surface of the strip-shaped fixing tooth facing the rubber strip, and a cylindrical spring positioning groove located inside the hollow metal shell is provided on the outer side of the return spring.

[0009] Preferably, a protective cover plate is provided below the single-cylinder, located on the lower end face of the hollow metal shell, and the hollow metal shell and the protective cover plate are fixed together by screws.

[0010] Preferably, a computer case placement plate is provided between the four slides, and the computer case placement plate is fixed at the middle position of the upper surface of the fixture table.

[0011] Preferably, a strip-shaped groove is provided on the outer side of the two clamps located on the upper end face of the same hollow metal shell, and both ends of the clamps are slidably connected to the strip-shaped groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses four hollow metal shells for fixing the computer shell, which are slidably installed inside four sliding grooves. When it is necessary to use the equipment to fix the computer shell, the four hollow metal shells are moved to positions corresponding to the length and width of the computer shell. Then, the computer shell is placed upside down on the computer shell placement plate. During the placement of the computer shell, the four sides of the computer shell will respectively enter between two clamps located on the upper end face of the four hollow metal shells. Then, by pushing the push plate upward with a single-cylinder, the clamps are pushed towards the computer shell to fix the computer shell. Through the above technical solution, pressure can be applied simultaneously to the inside and outside of the same position on the four sides of the computer shell. This ensures that the equipment can adapt to computer shells of various sizes while preventing the computer shell from deforming due to pressure. 2. In this utility model, when the push plate is pushed upward by a single-cylinder cylinder, the push plate first pushes outward two strip-shaped fixing teeth located on the outer surface of the hollow metal shell. As the strip-shaped fixing teeth are gradually pushed outward, the teeth on the strip-shaped fixing teeth will bite into the interior of the rubber strip fixed to the inner wall of the slide groove, thereby fixing the hollow metal shell. Through the above technical solution, after changing the overall position of the hollow metal shell according to the size of the computer shell, the hollow metal shell can be automatically fixed during the computer shell fixing operation. This prevents the hollow metal shell from moving under the action of external force when fixing computer shells of the same size in the future, thus preventing the need to readjust the position of the hollow metal shell.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] The 7 (model JX110), single-cylinder cylinder 8 (model SC-32) and rubber strip 13 (model ds-00001) mentioned in this utility model can be obtained from the market or through private customization.

[0017] Please see Figures 1 to 4This utility model provides an embodiment of a fixture for processing computer casings, including a fixture table 1. Each of the four corners of the upper surface of the fixture table 1 has a sliding groove 3. A hollow metal shell 4 is slidably installed inside the sliding groove 3. A single-cylinder cylinder 8 is fixedly installed on the lower side inside the hollow metal shell 4. The piston rod of the single-cylinder cylinder 8 is connected to a push plate 9. A push sleeve 14 is fixedly installed at the middle position of the upper surface of the push plate 9. A metal rod 6 is fixed to the upper side inside the hollow metal shell 4 above the push sleeve 14. A spring 7 is sleeved at the middle position of the outer surface of the metal rod 6. Both ends of the spring 7 are connected to a chuck 5 that is movably sleeved on the outer surface of the metal rod 6, and the surface of the chuck 5 facing the push sleeve 14 is a second inclined surface 15. Before using this equipment, the equipment is fixedly installed on a processing device, and the four single-cylinder cylinders 8 on the equipment are connected to the control system on the processing device. Four hollow metal shells 4 for fixing the computer case are slidably installed inside four slide grooves 3. When it is necessary to use the equipment to fix the computer case, the four hollow metal shells 4 are moved to positions corresponding to the length and width of the computer case.

[0018] A computer case placement plate 2 is provided between the four slides 3, and the computer case placement plate 2 is fixed in the middle position of the upper end face of the fixture table 1. After the position of the hollow metal shell 4 is adjusted, the computer shell is inverted and placed on the computer case placement plate 2. During the placement of the computer shell, the four sides of the computer shell will respectively enter the two clamps 5 located on the upper end face of the four hollow metal shells 4. After the computer shell is placed, the single-cylinder cylinder 8 is activated to push the push plate 9 upward. During the upward movement of the push plate 9, the push sleeve 14 fixed on the upper end face of the push plate 9 will move upward together. As the push sleeve 14 rises, the inlets on both sides of the push sleeve 14 will respectively contact the second inclined surface 15 located on the outer surface of the clamp 5. Under the action of the second inclined surface 15, as the push sleeve 14 rises, the two clamps 5 located on the upper end face of the same hollow metal shell 4 will be pushed towards the computer shell to fix the computer shell. The above technical solution can simultaneously apply pressure to the inside and outside of the same position on all four sides of the computer case, ensuring that the device can adapt to computer cases of various sizes while preventing the computer case from deforming due to pressure. When the chuck 5 is pushed toward the computer casing, it will compress the spring 7 connected to it. When it is necessary to remove the fixed computer casing, the push sleeve 14 is pulled down by the single-cylinder cylinder 8. As the push sleeve 14 moves downward, the reaction force of the compressed spring 7 can automatically push the chuck 5 outward, thereby releasing the fixation on the computer casing.

[0019] Both sides of the upper surface of the push plate 9 are first inclined surfaces 11. Above the first inclined surfaces 11 are strip-shaped fixing teeth 10 that are slidably connected to the hollow metal shell 4. One side of the strip-shaped fixing teeth 10 is provided with a rubber strip 13 fixed to the inner wall of the slide groove 3, and the toothed side of the strip-shaped fixing teeth 10 faces the rubber strip 13. A return spring 12 is connected to both sides of the side of the strip-shaped fixing teeth 10 facing the rubber strip 13. A cylindrical spring positioning groove located inside the hollow metal shell 4 is provided on the outer side of the return spring 12. The single-cylinder cylinder 8... When the push plate 9 and the push sleeve 14 are pushed upward, before the push sleeve 14 contacts the clamp 5, the two first inclined surfaces 11 on both sides of the upper end face of the push plate 9 will contact the lower end face of the strip fixing teeth 10 respectively. Under the action of the first inclined surfaces 11, as the push plate 9 rises, the strip fixing teeth 10 will be gradually pushed outward. As the strip fixing teeth 10 are gradually pushed outward, the teeth on the strip fixing teeth 10 will bite into the interior of the rubber strip 13 fixed to the inner wall of the slide groove 3, thereby fixing the hollow metal shell 4. By using the above technical solution to change the overall position of the hollow metal shell 4 according to the size of the computer shell, the hollow metal shell 4 can be automatically fixed during the computer shell fixing operation. This prevents the hollow metal shell 4 from moving under the action of external force when fixing computer shells of the same size in the future, which would require readjusting the position of the hollow metal shell 4. When the first inclined surface 11 on the outer surface of the push plate 9 passes the strip fixing tooth 10, and the plane on the outer surface of the push plate 9 comes into contact with the strip fixing tooth 10, the strip fixing tooth 10 will no longer be pushed outward as the push plate 9 rises. When the computer shell is released from its fixation, but the next computer shell to be processed is the same size as the computer shell that was just released from its fixation, do not pull the push plate 9 back to its original position. Ensure that the plane on the outer surface of the push plate 9 is always in contact with the strip fixing tooth 10 to prevent the fixation of the hollow metal shell 4 from being released. When the strip-shaped fixing tooth 10 is pushed outward, it will compress the reset spring 12 connected to it. When it is necessary to change the position of the hollow metal shell 4 according to the size of the new computer shell, the push plate 9 is pulled back to its original position by the single-bar cylinder 8. During the process of the push plate 9 moving towards its original position, the reaction force of the compressed reset spring 12 can push the strip-shaped fixing tooth 10 inward, thereby releasing the fixation of the hollow metal shell 4.

[0020] Two clamps 5 located on the upper surface of the same hollow metal shell 4 are provided with a strip-shaped groove on the outer side of the upper surface of the hollow metal shell 4, and both ends of the clamps 5 are slidably connected to the strip-shaped groove; the strip-shaped groove can prevent the clamps 5 from tilting.

[0021] The single-cylinder cylinder 8 is provided with a protective cover plate located on the lower end face of the hollow metal shell 4, and the hollow metal shell 4 and the protective cover plate are fixed together by screws; the protective cover plate can seal and protect the single-cylinder cylinder 8.

[0022] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
