Description

Technical Field

[0001] This invention belongs to the technical field of novel machining and manufacturing processes for mechanical parts, and in particular relates to a machining and manufacturing process for thin-walled aluminum curved mask parts. Background Technology

[0002] Aluminum curved mask is a relatively delicate metal part. During processing, it is necessary to strictly ensure the dimensional accuracy and geometric tolerances of the part. This part is a typical thin-walled part, characterized by its very thin walls and poor rigidity.

[0003] The existing manufacturing processes have the following main problems when processing this part:

[0004] 1. Since the part is made of aluminum, which is lightweight and has poor rigidity, existing equipment mainly uses clamps to hold and fix the part. During clamping, the overall shape of the part will inevitably be damaged, and the part is prone to elastic deformation, which makes it impossible to guarantee the accuracy of the part.

[0005] 2. Due to the unusual shape of the part and its arc-shaped cross-section, the inner surface of the part is prone to deformation and cracking when milling and drilling, due to friction and the poor rigidity of the part.

[0006] 3. In the existing technology, when drilling this part, the drill bit cannot completely guarantee the accuracy of the drill bit's feed and that the drill body will not deflect. Even slight deflection may lead to inaccurate hole positioning or cause overall breakage and deformation at the hole location. Summary of the Invention

[0007] The purpose of this invention is to address the problems mentioned in the background section by providing a processing and manufacturing process for thin-walled aluminum curved mask parts.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a manufacturing process for thin-walled aluminum curved mask parts, including a base base, a connecting seat rotatably connected to the base base, a cup-shaped suction cup seat fixedly connected to the connecting seat, and a part adsorption mechanism provided on the cup-shaped suction cup seat;

[0009] Both sides of the base are provided with L-shaped support frames, and clamping arms are fixedly connected to the L-shaped support frames. A drive motor is fixedly connected between the two clamping arms. A hydraulic cylinder is coaxially fixedly connected to the output end of the drive motor. A strip drill bit is coaxially fixedly connected to the output end of the hydraulic cylinder. An anti-deformation mechanism is provided between the two L-shaped support frames.

[0010] Furthermore, the part adsorption mechanism includes a piston cylinder, a piston plate, a connecting rope, and a counterweight ball. The three piston cylinders are located at the bottom of the cup-shaped suction cup seat and are connected to the cup-shaped suction cup seat. The piston plate is slidably connected inside the piston cylinder, the connecting rope is connected to the bottom of the piston plate, and the counterweight ball is connected to the end of the connecting rope away from the piston plate.

[0011] Furthermore, the anti-deformation mechanism includes a ring coil, a discharge plate, a ring rubber airbag, a rotating frame, and a stator sleeve. The ring coil is fixedly connected between two L-shaped support frames, the rotating frame is fixedly connected to the clamping arm, the stator sleeve is rotatably connected to the bottom of the two rotating frames, the discharge plate is electrically connected to the ring coil, the ring rubber airbag is disposed in a cup-shaped suction cup seat, and the discharge plate is disposed in the ring rubber airbag.

[0012] Furthermore, the stator sleeve has four filling chambers, each containing a bar magnet, and an arc-shaped damping plate is fixedly connected to the bar magnet near the axis of the stator sleeve.

[0013] Furthermore, an annular sliding plate is fixedly connected to the bottom of the annular rubber airbag, and an annular base plate is coaxially fixedly connected to the strip drill bit.

[0014] Furthermore, three buffer springs are fixedly connected to the annular base plate, and an annular mating plate is fixedly connected to the top of the three buffer springs.

[0015] Furthermore, a linkage shaft is rotatably connected to the base, and both the linkage shaft and the strip drill bit are coaxially and fixedly connected to pulleys, with a belt sleeved between the two pulleys.

[0016] Furthermore, both the linkage shaft and the connecting seat are coaxially fixedly connected with transmission gears, and the two transmission gears mesh with each other.

[0017] Compared with existing technologies, the advantages of this invention are:

[0018] 1. This invention sets up a part adsorption mechanism. Since the part is closely attached to the cup-shaped adsorption seat, when the cup-shaped adsorption seat rotates, the centrifugal force will swing the counterweight ball. The counterweight ball drives the piston plate to move in the piston cylinder, and the part will be tightly adsorbed. This fixing method not only ensures the normal processing of the part, but also avoids the deformation of the part caused by fixing.

[0019] 2. This invention sets up an anti-deformation mechanism, which uses the rotation of the strip drill bit to drive the stator sleeve to rotate. The magnetic poles inside the stator sleeve cooperate with the ring coil to generate electricity. The ring rubber air bag stores electrorheological fluid, which adheres to the inner wall of the part under normal conditions. When the strip drill bit rotates, the discharge plate causes the electrorheological fluid to solidify, thereby tightly adhering to the part and preventing deformation of the part surface during subsequent processing.

[0020] 3. The present invention provides an arc-shaped damping plate on the bar magnet inside the stator sleeve. The arc-shaped damping plate can ensure the stability of the axis of the bar drill head and prevent the bar drill bit from causing inaccurate drilling or cracking and deformation of the drill surface due to slight deflection.

Detailed Implementation

[0028] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0029] like Figures 1-6 As shown, a manufacturing process for a thin-walled aluminum curved mask part includes:

[0030] A base 1 is rotatably connected to a connecting seat 2. A cup-shaped suction cup seat 3 is fixedly connected to the connecting seat 2. The cup-shaped suction cup seat 3 is equipped with a part adsorption mechanism, and the cup-shaped suction cup seat 3 can fit tightly with the part.

[0031] Both sides of the base 1 are provided with L-shaped support frames 4. Clamping arms 5 are fixedly connected to the L-shaped support frames 4. A drive motor 6 is fixedly connected between the two clamping arms 5. A hydraulic cylinder 7 is fixedly connected to the output end of the drive motor 6 on the same axis. A strip drill bit 8 is fixedly connected to the output end of the hydraulic cylinder 7 on the same axis. An anti-deformation mechanism is provided between the two L-shaped support frames 4. The drive motor 6 can drive the strip drill bit 8 to perform drilling operations. The hydraulic cylinder 7 can control the strip drill bit 8 to perform cutting and retraction.

[0032] The part adsorption mechanism includes piston cylinders 9, piston plates 10, connecting ropes 11, and counterweight balls 12. The three piston cylinders 9 are located at the bottom of the cup-shaped suction cup seat 3 and are connected to the cup-shaped suction cup seat 3. The piston plates 10 are slidably connected inside the piston cylinders 9, the connecting ropes 11 are connected to the bottom of the piston plates 10, and the counterweight balls 12 are connected to the end of the connecting ropes 11 away from the piston plates 10. When the cup-shaped suction cup seat 3 rotates at high speed, the counterweight balls 12 are flung under the action of centrifugal force, the piston plates 10 are pulled, and high pressure is generated. The parts inside the cup-shaped suction cup seat 3 will be tightly adsorbed. This fixing method not only ensures the normal processing of the parts, but also avoids the deformation of the parts caused by fixing them.

[0033] The anti-deformation mechanism includes a ring coil 13, a discharge plate 14, a ring rubber airbag 15, a rotating frame, and a stator sleeve 16. The ring coil 13 is fixedly connected between two L-shaped support frames 4, the rotating frame is fixedly connected to the clamping arm 5, and the stator sleeve 16 is rotatably connected to the bottom of the two rotating frames. The discharge plate 14 is electrically connected to the ring coil 13. The ring rubber airbag 15 is located inside the cup-shaped suction cup seat 3. The stator sleeve 16 has four filling chambers 17, each containing a bar magnet. An arc-shaped damping plate 18 is fixedly connected to the bar magnet near the axis of the stator sleeve 16. A ring slide plate 19 is fixedly connected to the bottom of the ring rubber airbag 15. A bar drill bit 8 is coaxially fixedly connected to a ring base plate, and three buffer springs 2 are fixedly connected to the ring base plate. 0. Three buffer springs 20 are fixedly connected to an annular mating plate 21 at the top. The annular rubber airbag 15 is filled with electrorheological fluid. When there is no electric field in the surrounding area, the electrorheological fluid is in a liquid state. At this time, the annular rubber airbag 15 is attached to the inner wall of the part. When the stator sleeve 16 rotates with the rotation of the bar drill bit 8, the bar magnet and the annular coil 13 interact to generate current, which is discharged through the discharge plate 14. The electrorheological fluid in the annular rubber airbag 15 solidifies. At this time, the annular rubber airbag 15 is tightly attached to the inner wall of the part. The bar drill bit 8 can perform drilling operation under the action of the drive motor 6. By setting an arc-shaped damping plate 18 on the bar magnet in the stator sleeve 16, the arc-shaped damping plate 18 can ensure the stability of the axis of the bar drill bit 8 and avoid the bar drill bit 8 from being inaccurate in drilling or causing the drill surface to crack and deform due to slight deflection.

[0034] A linkage shaft 22 is rotatably connected to the base 1. Both the linkage shaft 22 and the strip drill bit 8 are coaxially fixedly connected to pulleys 23. A belt is sleeved between the two pulleys 23. Both the linkage shaft 22 and the connecting seat 2 are coaxially fixedly connected to transmission gears 24. The two transmission gears 24 mesh with each other. When the strip drill bit 8 rotates, the linkage shaft 22 can rotate through the pulleys 23 and the belt. The transmission gears 24 coaxially fixedly connected to the linkage shaft 22 can drive the connecting seat 2 to rotate in the opposite direction. Since the cup-shaped suction cup seat 3 and the strip drill bit 8 rotate in opposite directions, the drilling efficiency can be further improved.

[0035] The working principle of this invention is as follows:

[0036] The cup-shaped suction cup seat 3 can fit tightly with the part, the drive motor 6 can drive the strip drill bit 8 to perform drilling operations, and the hydraulic cylinder 7 can control the strip drill bit 8 to advance and retract.

[0037] When the cup-shaped suction cup seat 3 rotates at high speed, the counterweight ball 12 is flung under the action of centrifugal force, the piston plate 10 is pulled, and high pressure is generated. The parts inside the cup-shaped suction cup seat 3 will be tightly attracted. This fixing method not only ensures the normal processing of the parts, but also avoids the deformation of the parts caused by fixing them.

[0038] The annular rubber bladder 15 is filled with electrorheological fluid. When there is no electric field in the surrounding environment, the electrorheological fluid is in a liquid state. At this time, the annular rubber bladder 15 is attached to the inner wall of the part. When the stator sleeve 16 rotates with the rotation of the bar drill bit 8, the bar magnet interacts with the annular coil 13 to generate current, which is discharged through the discharge plate 14. The electrorheological fluid in the annular rubber bladder 15 solidifies. At this time, the annular rubber bladder 15 is tightly attached to the inner wall of the part. The bar drill bit 8 can perform drilling operation under the action of the drive motor 6. By setting an arc-shaped damping plate 18 on the bar magnet in the stator sleeve 16, the arc-shaped damping plate 18 can ensure the stability of the axis of the bar drill bit 8 and avoid inaccurate drilling or cracking and deformation of the drill surface due to slight deflection of the bar drill bit 8.

[0039] When the bar drill bit 8 rotates, the linkage shaft 22 can rotate through the pulley 23 and belt drive. The transmission gear 24, which is coaxially fixed to the linkage shaft 22, can drive the connecting seat 2 to rotate in the opposite direction. Since the cup-shaped suction cup seat 3 and the bar drill bit 8 rotate in opposite directions, the drilling efficiency can be further improved.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
