Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy shell cutting and grinding technology, specifically to an aluminum alloy shell cutting and grinding device. Background Technology

[0002] In modern industry, aluminum alloys are widely used in many industries such as electronic equipment, automobile manufacturing, aerospace, and medical devices due to their excellent properties such as light weight, high strength, and corrosion resistance. As an important component of these devices, the processing precision and surface quality of aluminum alloy housings directly affect the performance and service life of the products.

[0003] Traditional aluminum alloy casing cutting and grinding operations are mostly completed manually or with semi-automated equipment. In manual operation, workers need to hold cutting and grinding tools by hand, which is not only labor-intensive and inefficient, but also the processing quality is heavily dependent on the operator's skills and experience, which can easily lead to problems such as dimensional deviations and inconsistent surface roughness, making it difficult to meet the needs of high-precision, mass production.

[0004] The large amount of debris and dust generated during the cutting and polishing of aluminum alloy casings poses a significant hazard. Fine dust can be easily inhaled by operators, damaging their respiratory tract and lungs and causing occupational diseases. Furthermore, aluminum alloy dust is flammable, and when it floats or accumulates, sparks generated during cutting can easily ignite it. If the dust reaches a certain concentration, it can cause an explosion, which not only damages the equipment but also seriously threatens the lives of personnel, posing a major safety hazard.

A rack 205 is provided, with its other end fixedly connected to one side of a connecting seat 207. Sliding rods 206 are fixedly connected to both ends of the connecting seat 207 on opposite sides of the upper inner wall of the U-shaped plate 201.

Since the rack 205 on the right side of the connecting seat 207 meshes with the circular gear 203, the circular gear 203 rotates accordingly, which in turn drives the rack 205 on the left side of the connecting seat 207 to move, so that the left connecting seat 207 moves closer to the right connecting seat 207 in sync, until the two fixing plates 209 firmly clamp the aluminum alloy shell. During the clamping process, the cooperation between the T-shaped slider 208 and the slide groove and the limiting effect of the sliding rod 206 ensure the smoothness and accuracy of the movement of the connecting seat 207.

The rotating rod 602 passes through the center of the cutting blade 7 and is fixedly connected to the output shaft end of the servo motor 6. By starting the servo motor 6, the servo motor 6 drives the outer housing... 1. The internal rotating rod 602 rotates, which in turn drives the cutting blade 7 fixed at the center to rotate. The rotating shaft 16 at the other end also rotates. Through the transmission belt 15, the rotating shaft 14 rotates. It has the advantages of smooth transmission and shock absorption. It can effectively transmit the power of the rotating shaft 14 to the rotating shaft 16. The bevel gear 604 fixedly connected to the other end of the rotating shaft 14 rotates, which drives the meshing bevel gear 603 above to rotate, so that the grinding disc 8 works to grind the surface of the cut metal parts and remove the burrs and unevenness generated by cutting.

[0026] Reference Figure 2A connecting rod 11 is fixedly connected to the rear end surface of the U-shaped plate 201 through the rear end of the protective cover 3. A connecting rod 22 is fixedly connected to the other end of the connecting rod 11. A connecting rod 33 is fixedly connected to the other end of the connecting rod 22. The other end of the connecting rod 313 passes through the interior of the outer housing 1 and is fixedly connected to one side surface of the U-shaped plate 201. An electric push rod 20 is fixedly connected to the rear end surface of the outer housing 1. The output end of the electric push rod 210 is fixedly connected to the center point of the connecting rod 22. When the electric push rod 210 is started, the output end drives the connecting rod 11 and the connecting rod 313 through the connecting rod 212 to move the U-shaped plate 201 along the T-shaped groove 210 of the sliding base 211 toward the cutting blade 7, so that the aluminum alloy shell can reach the cutting position and the grinding position.

[0027] Reference Figure 1 , Figure 4 The upper sides of the outer casing 1 are fixedly connected to sliding bases 211. The surface of the sliding base 211 is provided with a T-shaped groove 210. The lower end of the U-shaped plate 201 is slidably connected to the sliding base 211 through the T-shaped groove 210. The upper surface of the protective cover 3 is provided with a cover plate 4. The rear top of the protective cover 3 is rotatably connected to the rear end of the cover plate 4 through a rotating shaft 9. The cover plate 4, which can be rotated by the rotating shaft 9, forms a relatively closed space, effectively blocking the splashing of dust and debris and the diffusion of noise. If it is necessary to inspect or maintain the internal components of the device, the cover plate 4 can be opened by rotating the rear rotating shaft 9 of the cover plate 4.

[0028] The working principle and usage process of this utility model are as follows: After the aluminum alloy shell is placed between the two fixing plates 209 of the fixing component 2, the electric push rod 202 is activated, and its output end pushes the connecting plate to move. The connecting plate drives the right connecting seat 207 to slide along the T-shaped slider 208 and sliding rod 206 on the inner wall of the U-shaped plate 201. Since the rack 205 on one side of the right connecting seat 207 meshes with the circular gear 203 at the center of the U-shaped plate 201, the circular gear 203 rotates as the right rack 205 moves, thereby driving the rack 205 on the left connecting seat 207 to move in the opposite direction. This causes the left connecting seat 207 to move synchronously towards the right connecting seat 207, and finally the aluminum alloy shell is firmly clamped by the two fixing plates 209. The cooperation between the T-shaped slider 208 and the slide groove and the limiting of the sliding rod 206 ensure the smooth movement and clamping accuracy of the connecting seat 207. The power transmission for cutting and grinding is driven by the output shaft of the servo motor 6 to drive the rotating rod 602 to rotate. The rotating rod 602 directly drives the cutting blade 7 to rotate. At the same time, the rotating rod 602 drives the second rotating shaft 16 to rotate synchronously. The second rotating shaft 16 drives the first rotating shaft 14 to rotate through the belt 15. The other end of the first rotating shaft 14 The second bevel gear 604 rotates accordingly. Because the second bevel gear 604 meshes with the first bevel gear 603 at the lower end of the grinding disc 8, it drives the grinding disc 8 to rotate, realizing the linkage operation of the cutting blade 7 and the grinding disc 8, meeting the power requirements for cutting and grinding. When the output end of the electric push rod 210 extends or retracts, the U-shaped plate 201 slides along the T-shaped groove 210 of the sliding base 211 through the connecting rod 11, connecting rod 22 and connecting rod 313, so that the aluminum alloy shell on the fixed component 2 can be accurately moved to the cutting blade 7 to complete the cutting, and then moved to the grinding disc 8 for grinding. The cutting and grinding processes are carried out continuously. During the processing, the protective cover 3 and the cover plate 4, which can be rotated by the rotating shaft 9, form a closed space to prevent debris from flying and noise from spreading. At the same time, the exhaust fan 5 is started, and the dust suction cover 601 on the outer side of the lower end of the cutting blade 7 sucks the dust and debris generated during cutting into the filter box 502 through the connecting pipe 1 501. The dust and debris in the grinding area and surrounding area enter the filter box 502 through three dust suction pipes 505, connecting pipe 3 504, and connecting pipe 2 503, so as to effectively collect and treat the dust and debris generated during the processing and ensure the safety and cleanliness of the processing environment.
