Description

Technical Field

[0001] This invention relates to the field of polishing technology, specifically a polishing machine tool for integrated polishing of the inner and outer walls of aluminum alloy door frames. Background Technology

[0002] During the production of doors and windows, the surface of the doors and windows needs to be polished, and polishing machines are used in this process. For example, the utility model patent with announcement number CN220094198U relates to the field of aluminum alloy door and window manufacturing equipment technology, and discloses a polishing device for aluminum alloy door and window manufacturing, including a processing table, a first threaded rod installed on the upper part of the processing table, a connecting plate connected to the external thread of the first threaded rod, a second hydraulic telescopic rod fixedly connected to the upper part of the connecting plate, and a horizontal plate installed on the inner side of the upper part of the second hydraulic telescopic rod.

[0003] Taking the aforementioned polishing device as an example, during the application of the polishing device, the clamping and fixing structure fixes the position of the aluminum alloy door frame. During the grinding and polishing process, the relative position between the clamping and fixing structure and the aluminum alloy door frame remains unchanged, which means that the polishing device can only mechanically grind and polish the aluminum alloy door frame surface that is not in contact with the clamping and fixing structure. When it is necessary to polish the side walls or inner walls of different planes of the aluminum alloy door frame, the operator needs to operate and position the aluminum alloy door frame multiple times, which affects the polishing speed of the aluminum alloy door frame.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1-15 As shown, this invention provides a polishing machine tool for integrated polishing of the inner and outer walls of aluminum alloy door frames, including a main machine tool structure 1. The main machine tool structure 1 includes a processing box 11, a top cover 12, and a manifold 111. A water supply component is installed at the bottom of the top cover 12. A clamping structure 2 is installed on the processing box 11. The clamping structure 2 includes two side support components and a lower support component. The lower support component includes a fixed seat 27 fixedly connected inside the manifold 111, a pneumatic cylinder 29 fixedly inserted on the fixed seat 27, a fixed seat 210 fixedly connected to the piston end of the pneumatic cylinder 29, a control motor 213 fixedly connected to the top of the fixed seat 210, and a dual-axis hydraulic cylinder 216 and a dual-axis hydraulic... Two clamping frames 218 are fixedly connected to the two piston ends of the pressure cylinder 216. The processing box 11 is equipped with two driving structures 3. One of the driving structures 3 has a grinding structure 6 on its top. The grinding structure 6 includes a control component, a fixed frame 62 driven by the control component, and a fixed plate 67 fixedly connected to the fixed frame 62. Multiple dampers 68 are fixedly connected to both sides of the fixed plate 67. A fixed plate 69 is fixedly connected between the piston ends of the multiple dampers 68 on the same side. A U-shaped frame 611 and a U-shaped frame 618 are fixedly connected between the two fixed plates 69. A multi-directional polishing component is installed between the two U-shaped frames 611. The other driving structure 3 is equipped with a drive motor 4 and a grinding roller 5 on its top.

[0021] The polishing machine tool, consisting of a main machine tool structure 1, a clamping structure 2, two drive structures 3, a drive motor 4, a grinding roller 5, and a grinding structure 6, is used to polish the inner and outer walls of an aluminum alloy door frame 7 simultaneously. The connection of the polishing machine tool to a human-machine interface device to control its operation is an existing technology and will not be described in detail here.

[0022] Specifically: such as Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 15 As shown; Multiple telescopic rods 28 are fixedly threaded through the fixed base 3 27. The piston ends of the telescopic rods 28 are fixedly connected to the fixed base 4 210. Under the action of the telescopic rods 28 and the pneumatic cylinder 29, the fixed base 4 210 moves up and down. The top of the fixed base 5 211, which is fixedly connected to the top of the fixed base 4 210, is rotatably connected to the top of the fixed base 7 219. The top of the fixed base 7 219 is fixedly connected to the fixed base 6 212, which can rotate relative to the top of the fixed base 4 210. A dual-axis hydraulic cylinder 216 is fixedly threaded through the fixed base 6 212. The fixed base 6 212 rotates synchronously with the dual-axis hydraulic cylinder 216. Two telescopic rods 217 are fixedly threaded through the fixed base 6 212. The piston ends of the two telescopic rods 217 are fixedly connected to two clamping frames 218 respectively. The telescopic rods 217 support and limit the clamping frames 218. The clamping frames 218 and the fixed base 6 212 can only move apart. The system is capable of horizontal movement. By controlling the operation of the dual-axis hydraulic cylinder 216, the two clamping frames 218 can be moved away from or closer to each other. The output end of the control motor 213, which is fixedly connected to the top of the fixed base 4 210, is fixedly connected to the fixed base 6 212 via a transmission shaft 214. Controlling the operation of the control motor 213 drives the fixed base 6 212 to rotate via the transmission shaft 214, causing the two clamping frames 218 to rotate. A brake 215 is sleeved on the outside of the transmission shaft 214 and is fixedly installed inside the fixed base 5 211. After the control motor 213 has finished working, the brake 215 is activated to brake the transmission shaft 214. The fixed base 6 212 is braked, and the two clamping frames 218 cannot rotate around the transmission shaft 214, ensuring the stability and safety of the two clamping frames 218 in supporting the conveying aluminum alloy door frame 7.

[0023] When the polishing machine is working, the control pneumatic cylinder 29 pushes the fixed seat 210, fixed seat 212 and two clamping frames 218 to move upward, so that the top of the clamping frame 218 is flush with the top of the top cover 12. At this time, the horizontal structure of the clamping frame 218 is close to the inner wall of the top cover 12. Then, the aluminum alloy door frame 7 is horizontally lowered into the top cover 12. After the two clamping frames 218 support the aluminum alloy door frame 7, the control dual-axis hydraulic cylinder 216 increases the friction between the clamping frame 218 and the aluminum alloy door frame 7, so that the lower support assembly clamps and fixes the aluminum alloy door frame 7. Then, the control lower support assembly drives the aluminum alloy door frame 7 to move downward. The aluminum alloy door frame 7 moves downward toward the two side support assemblies in the drive structure 3.

[0024] Two side support assemblies are respectively set on the left and right sides of the processing box 11. In the side support assembly, the first fixing frame 21 is fixedly installed on the processing box 11. The piston end of the third pneumatic cylinder 22, which is fixedly installed inside the first fixing frame 21, is fixedly connected to the second fixing seat 24. Two clamping plates 25, which are fixedly connected to one side of the second fixing seat 24, are both set inside the processing box 11. A telescopic tube 26 is fixedly connected between the outer side of the second fixing seat 24 and the inner wall of the first fixing frame 21. The telescopic tube 26 cooperates with the first fixing frame 21 to protect the third pneumatic cylinder 22. The piston ends of the two telescopic rods 23, which are fixedly installed on the first fixing frame 21, are fixedly connected to the second fixing seat 24. Under the action of the telescopic rods 23 and the third pneumatic cylinder 22, the second fixing seat 24 and the two clamping plates 25 can only move left and right inside the processing box 11.

[0025] When the current support component moves the aluminum alloy door frame 7 between the two side support components, the control cylinder 22 pushes the fixing seat 24 to move towards the aluminum alloy door frame 7. The L-shaped clamping plate 25 supports the bottom and outer wall of the aluminum alloy door frame 7. Finally, the two side support components clamp and support the aluminum alloy door frame 7. The lower support component and the two side support components clamp and fix the aluminum alloy door frame 7, completing the fixing and positioning of the aluminum alloy door frame 7.

[0026] Subsequently, the two drive structures 3 are controlled to work. Since the pneumatic cylinder 32 is fixedly installed on the left side of the processing box 11, the guide rail 33 is fixedly connected to the piston end of the pneumatic cylinder 32 and is set inside the processing box 11. The fixed seat 36 inside the guide rail 33 is slidably connected and the pneumatic cylinder 310 is fixedly installed inside. The fixed seat 39, which is fixedly connected to the piston end of the pneumatic cylinder 310, is fixedly connected to the fixed seat 36. The telescopic tube 38 can be extended and retracted. The telescopic tube 38 is set to seal the pneumatic cylinder 310 without affecting the pneumatic cylinder 310's ability to push the fixed seat 39 up and down. The piston ends of the multiple telescopic rods 311 fixedly connected inside the fixed seat 36 are all fixedly connected to the fixed seat 39 to ensure the stability of the fixed seat 39's movement.

[0027] The piston end of the pneumatic cylinder 35, which is fixedly connected inside the guide rail 33, is also fixedly connected to the fixed seat 36. Controlling the operation of the pneumatic cylinder 35 controls the forward and backward movement of the fixed seat 36. Support rods 34 are installed at both ends of the guide rail 33. The support rods 34 are fixedly installed inside the processing box 11 to support and guide the guide rail 33. The guide rail 33 can move left and right inside the processing box 11. A telescopic tube 31 is fixedly connected between the guide rail 33 and the inner wall of the processing box 11. The telescopic tube 31 is sleeved on the outside of the pneumatic cylinder 32. The telescopic tube 31, which can extend and retract, provides protection for the pneumatic cylinder 32 without affecting the left and right movement of the guide rail 33. Controlling the operation of the pneumatic cylinder 32 controls the left and right movement of the guide rail 33 inside the processing box 11, and also controls the left and right movement of the fixed seat 36, the pneumatic cylinder 310, and the fixed seat 39.

[0028] Therefore, the control drive structure 3 works, and the fixed seat 9 39 can move up and down, forward and backward, and left and right inside the main body structure 1 of the machine tool.

[0029] A telescopic component 37 is fixedly installed on the outside of the fixed base 36. Both ends of the telescopic component 37 are fixedly connected to the guide rail 33. The U-shaped telescopic component 37 covers the top of the guide rail 33. The telescopic component 37 provides protection for the pneumatic cylinder 35.

[0030] The drive motor 4 is fixedly installed on the top of the front mounting base 39, and the polishing roller 5 is fixedly installed on the outside of the output end of the drive motor 4. The front drive structure 3 drives the polishing roller 5 to move, so that the polishing roller 5 polishes the front side of the aluminum alloy door frame 7.

[0031] In the control assembly, the forward and reverse motor 64 is fixedly installed on the top of the rear fixed base 39. The output end of the forward and reverse motor 64 is fixedly connected to the transmission shaft 2 65 between the fixed end and the fixed frame 3 62. The outer side of the forward and reverse motor 64 is fitted with the fixed frame 2 61, which is fixedly installed on the top of the fixed base 39. The top of the inner cavity of the fixed frame 2 61 is rotatably connected to the fixed frame 4 63, which is fixedly connected to the fixed frame 3 62. The fixed frame 3 62 and the fixed base 39 can rotate relative to each other to control the operation of the forward and reverse motor 64. The forward and reverse motor 64 drives the fixed frame 3 62 to rotate on the top of the fixed base 39 through the transmission shaft 2 65. The brake 2 66 is fixedly connected inside the fixed frame 2 61 and fitted on the outer side of the transmission shaft 2 65. After the forward and reverse motor 64 finishes working, the brake 2 66 works to brake the transmission shaft 2 65, and the fixed frame 3 62 is braked to ensure the stability of the position control of the fixed frame 3 62.

[0032] A fixing plate 67 is fixedly connected to the top of the fixing frame 62. Multiple dampers 68 are fixedly connected to both sides of the fixing plate 67. A fixing plate 69 is fixedly connected between the piston ends of the multiple dampers 68 on the same side. After the fixing plate 69 is subjected to a certain force, the dampers 68 installed on the fixing plate 69 contract, and the relative position between the fixing plate 69 and the fixing plate 67 changes. A hydraulic sensor 610 is fixedly installed on the outside of two dampers 68. These two dampers 68 are fixedly connected to two fixing plates 69 respectively. After the fixing plate 69 moves, the corresponding hydraulic sensor 610 detects the change in hydraulic value.

[0033] Two fixed plates 69 are fixedly connected by U-shaped frames 611 and 618. In the multi-directional polishing assembly, drive motor 612 is fixedly mounted on U-shaped frame 611, and drive shaft 616 is rotatably mounted on U-shaped frame 618. Grinding rollers 617 are fixedly installed at both ends of drive shaft 616. Gearbox 613 is fixedly connected between U-shaped frame 611 and U-shaped frame 618. The output end of drive motor 612 is fixedly connected to the input end of gearbox 613. Gear 614 fixedly connected to the outside of the output end of gearbox 613 meshes with gear 615 fixedly installed on the outside of drive shaft 616. Therefore, drive motor 612 is controlled to output rotational force. After being changed by gearbox 613, the rotational force is applied to drive shaft 616 through gear 614 and gear 615. Drive shaft 616 and the two grinding rollers 617 fixedly connected to drive shaft 616 rotate.

[0034] Two electromagnets 619 are fixedly mounted on the fixed plate 67. The control drive structure 3 operates to move the two grinding rollers 617 to contact the rear wall of the inner cavity of the aluminum alloy door frame 7. Then, the control drive structure 3 drives the grinding structure 6 to move to the right. When the right grinding roller 617 abuts against the right side of the inner cavity of the aluminum alloy door frame 7, the U-shaped frame 618 experiences a leftward force as the drive structure 3 operates. The right damper 68 contracts, and the hydraulic pressure detected by the right hydraulic sensor 610 increases. When the hydraulic pressure detected by the hydraulic sensor 610 reaches a preset value, the right fixed plate 619... 9. Two electromagnets 619 are pressed against each other. The working electromagnets 619 attract and fix the iron fixing plate 69. The two fixing plates 69 are fixed together by U-shaped frame 611 and U-shaped frame 618. Therefore, the relative position of U-shaped frame 611 and U-shaped frame 618 with fixing plate 67 in the left and right directions cannot change. One end of the grinding roller 617 on the right side presses against the right side of the inner cavity of the aluminum alloy door frame 7. The curved surface of the grinding roller 617 is aligned with the rear wall of the inner cavity of the aluminum alloy door frame 7. The grinding roller 617 covers the corner between the rear wall of the inner cavity of the aluminum alloy door frame 7 and the right side of the inner cavity.

[0035] Subsequently, the drive motor 612 is controlled to work. Under the action of the gearbox 613, gear 614, gear 615 and transmission shaft 616, the two grinding rollers 617 rotate. The drive structure 3 drives the grinding structure 6 to move up and down repeatedly for a period of time. Then the grinding structure 6 stops working. The drive structure 3 controls the grinding structure 6 to move to the left a certain distance. During this process, the electromagnet 619 stops working. Multiple dampers 68 drive the two fixed plates 69 to reset. The hydraulic value detected by the right hydraulic sensor 610 decreases. The friction between the grinding rollers 617 and the inner wall of the aluminum alloy door frame 7 is insufficient to make the hydraulic sensor 610 detect the preset hydraulic value. At the same time, the electromagnet 619 resumes working. After the grinding structure 6 moves to the left, the two grinding rollers 617 rotate. The drive structure 3 drives the grinding structure 6 to move up and down repeatedly for a period of time to grind and polish the rear wall of the aluminum alloy door frame 7.

[0036] The drive structure 3 and the grinding structure 6 work together to grind and polish the rear wall of the inner cavity of the aluminum alloy door frame 7 according to the above method. When the left grinding roller 617 abuts against the right side of the inner cavity of the aluminum alloy door frame 7, the U-shaped frame 618 is subjected to a rightward force as the drive structure 3 works, the left damper 68 contracts, and the hydraulic pressure detected by the left hydraulic sensor 610 increases. When the hydraulic pressure value detected by the hydraulic sensor 610 reaches the preset value, the left fixing plate 69 abuts against the two electromagnets 619, and the electromagnets 619 fix the position of the left fixing plate 69. The left grinding roller 617 covers the corner between the rear wall of the inner cavity of the aluminum alloy door frame 7 and the left side of the inner cavity. The grinding structure 6 works and the two grinding rollers 617 rotate. The drive structure 3 works and makes the grinding structure 6 move up and down for a period of time to complete the grinding and polishing work of the rear wall of the inner cavity of the aluminum alloy door frame 7 without dead angles.

[0037] After completing the thorough grinding and polishing of the rear wall of the inner cavity of the aluminum alloy door frame 7, the two drive structures 3 and the grinding structure 6 are reset, the two side support components are activated, the clamping plate 25 is reset, and then the lower support component is controlled to drive the aluminum alloy door frame 7 to rotate 90°. Next, the two side support components are controlled to clamp and fix the aluminum alloy door frame 7. The dual-axis hydraulic cylinder 216 in the lower support component is retracted, and the two clamping frames 218 move closer together, causing the pneumatic cylinder 29 to activate and drive the fixed seat 210 and fixed seat 212 to move downwards. After the clamping frame 218 moves to the bottom of the side support component, the control motor 213 activates again to drive the fixed seat 212, the dual-axis hydraulic cylinder 216, and the two clamping frames. 218 rotates 90°, and the two clamping frames 218 move away from the rear and front sides of the inner cavity of the aluminum alloy door frame 7. Finally, the lower support assembly is controlled to support the left and right sides of the interior of the aluminum alloy door frame 7, completing the reversal of the aluminum alloy door frame 7. The clamping structure 2 works so that the four inner walls and four outer walls of the aluminum alloy door frame 7 become the rear wall of the inner cavity to be processed and the front wall to be processed in sequence. Then, the two drive structures 3, drive motor 4, grinding roller 5 and grinding structure 6 are controlled to work together to grind and polish them, so as to complete the synchronous processing of the outer and inner walls of the aluminum alloy door frame 7. Under the premise of avoiding the occurrence of dead corners in the processing of the inner wall of the aluminum alloy door frame 7, the automated grinding and polishing of the inner and outer walls of the aluminum alloy door frame 7 is completed.

[0038] Specifically, such as Figure 10 , Figure 11 and Figure 12 As shown: The forward and reverse motor 64 drives the fixed frame 3 62 to rotate 90°, causing the grinding roller 2 617 to rotate 90°. Then, the drive structure 3 is controlled to move the grinding roller 2 617 to contact the top or bottom wall of the aluminum alloy door frame 7. After that, the grinding structure 6 is controlled to drive the grinding roller 2 617 to rotate. The drive structure 3 causes the grinding structure 6 to move left and right to grind and polish the top or bottom wall of the aluminum alloy door frame 7. The clamping structure 2 is controlled to move the top and bottom walls of the aluminum alloy door frame 7 at different positions onto the processing path of the grinding structure 6, thus completing the overall grinding and polishing of the aluminum alloy door frame 7. After the aluminum alloy door frame 7 is ground, the lower support assembly is controlled to push the aluminum alloy door frame 7 out of the processing box 11.

[0039] Furthermore, during the rotation of the aluminum alloy door frame 7 driven by the clamping structure 2, the position of the drive motor 4 and the grinding roller 5 is controlled by the drive structure 3, so that the grinding roller 5 can chamfer the outer wall edges of the aluminum alloy door frame 7, thus ensuring the versatility of the clamping structure 2.

[0040] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown: A groove 13 is provided on the top of the top cover 12. The housing of the dual-axis pneumatic cylinder 14 is fixedly connected to the main structure 1 of the machine tool inside the groove 13. Both piston ends of the dual-axis pneumatic cylinder 14 are fixedly connected to door panels 8. The door panels 8 are located on the top of the top cover 12. The operation of the dual-axis pneumatic cylinder 14 is controlled to push the two door panels 8 away from each other, so that the inside of the top cover 12 is exposed, providing a passage for the aluminum alloy door frame 7 to enter or leave the processing box 11.

[0041] The two door panels 8 and the dual-axis pneumatic cylinder 14 ensure the sealing of the processing box 11 during the grinding of the aluminum alloy door frame 7 inside the processing box 11, preventing debris from splashing. In the water supply assembly, the water guide pipe 16, the fixed seat 15, and the two pneumatic cylinders 110 are all fixedly installed at the bottom of the top cover 12. The piston ends of the two pneumatic cylinders 110 are fixedly connected to the water guide pipes 18. The two water guide pipes 18 are respectively set on both sides of the bottom of the top cover 12. The two water guide pipes 18 are symmetrically arranged. Multiple atomizing nozzles 19 are fixedly connected to the bottom of the outer side of the water guide pipes 18. Telescopic pipes 17 are fixedly connected to both ends of the water guide pipes 18. One end of one telescopic pipe 17 is fixedly connected to the fixed seat 15, and the other end of the telescopic pipe 17 is fixedly connected to the water guide pipe 16 fixedly connected to the processing box 11. Therefore, the water guide pipes 18 can move back and forth inside the processing box 11. One end of the water guide pipe 16 extends to the outside of the processing box 11 and connects to the water supply system.

[0042] The control cylinder 110 controls the position of the water guide pipe 18, causing the front water guide pipe 18 and its fixedly installed atomizing nozzles 19 to move onto the trajectory of the grinding roller 5, and the rear water guide pipe 18 and its fixedly installed atomizing nozzles 19 to move onto the trajectory of the grinding roller 617. During the grinding of the aluminum alloy door frame 7, water is supplied to the two water guide pipes 18 through the water guide pipe 16. The atomizing nozzles 19 atomize the water and spray it out to cool and lubricate the aluminum alloy door frame 7. At the same time, the sprayed water mist impacts the debris generated during the grinding and polishing of the aluminum alloy door frame 7, causing the debris to mix with water and fall into the manifold 111 fixedly installed at the bottom of the inner cavity of the processing box 11. This completes the collection of debris and the rinsing of the aluminum alloy door frame 7 during the grinding and polishing process. It can perform sealing processing on the aluminum alloy door frame 7 without affecting the polishing of the inner and outer walls of the aluminum alloy door frame 7, reducing the pollution of the working environment caused by the processing of the aluminum alloy door frame 7.

[0043] Furthermore, the bottom of the manifold 111 extends to the bottom of the processing box 11. A filter screen 112 is fixedly installed on the bottom outer side of the manifold 111. One end of the drain pipe 113 on one side of the filter screen 112 is fixedly connected to the outer wall of the manifold 111. Liquid entering the bottom of the inner cavity of the manifold 111 is filtered by the filter screen 112, debris is trapped at the bottom of the inner cavity of the manifold 111, and water is discharged into the drain pipe 113.

[0044] A base plate 114 is fixedly connected to the bottom of the blocking plate 115 at the bottom of the inner cavity of the manifold 111. A telescopic rod 116 and a pneumatic cylinder 117 are fixedly inserted through the bottom of the processing box 11. The piston ends of the telescopic rod 116 and the pneumatic cylinder 117 are both fixedly connected to the base plate 114. By controlling the operation of the pneumatic cylinder 117, the blocking plate 115 and the base plate 114 can be controlled to move up and down.

[0045] When it is necessary to clean the inside of the manifold 111, the control cylinder 117 is used to push the blockage plate 115 and the bottom plate 114 downward, so that the bottom of the manifold 111 is unobstructed, and the debris on the top of the blockage plate 115 can be collected and processed.

[0046] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
