Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of polishing the inner and outer side surfaces of two horizontal aluminum pieces and two arc-shaped aluminum pieces of a special-shaped aluminum profile, and particularly relates to a polishing device and method for a special-shaped aluminum profile. BACKGROUND

[0002] The structure of a certain special-shaped aluminum profile is shown in Figures 1-2 It comprises a hollow rectangular aluminum pipe 1, and a vertical solid aluminum piece 2 is fixedly arranged on the top surface of the hollow rectangular aluminum pipe 1 at the left and right ends. The top end of each vertical solid aluminum piece 2 is sequentially fixedly connected with an arc-shaped aluminum piece 3 and a horizontal aluminum piece 4. The arc-shaped aluminum piece 3 is outwardly curved, and the thickness of the arc-shaped aluminum piece 3 is equal to the thickness of the horizontal aluminum piece 4. The arc-shaped aluminum piece 3, the horizontal aluminum piece 4 and the hollow rectangular aluminum pipe 1 are formed by an extrusion machine.

[0003] The special-shaped aluminum profile is matched with a cross beam and a rain shield to build a rain shield assembly. After a batch of the special-shaped profiles are formed by the extrusion machine, a large number of burrs are formed on the inner and outer side surfaces of the two arc-shaped aluminum pieces 3 due to the extrusion process. Meanwhile, a large number of burrs are also formed on the inner and outer side surfaces of the two horizontal aluminum pieces 4. Due to the burrs, the workers are injured by the burrs when they build the rain shield assembly with the special-shaped aluminum profile. Therefore, the workers need to polish all the burrs on the arc-shaped aluminum pieces 3 and the horizontal aluminum pieces 4 of each special-shaped aluminum profile.

[0004] The method for polishing the burrs on the special-shaped aluminum profile by the workers is as follows:

[0005] S1. The worker takes out a special-shaped aluminum profile to be polished, and places the hollow rectangular aluminum pipe 1 of the special-shaped aluminum profile on the table surface of a tooling table;

[0006] S2. The worker fixes the hollow rectangular aluminum pipe 1 of the special-shaped aluminum profile on the tooling table by the pressing plate of the pressing plate clamping mechanism on the tooling table;

[0007] S3. The worker holds the handle of a polisher, and then turns on the polisher. The polisher drives the polishing rod 5 thereon to rotate around its own axis;

[0008] S4. The burrs on the inner and outer side surfaces of the right arc-shaped aluminum piece 3 and the right horizontal aluminum piece 4 are polished. The specific operation steps are as follows:

[0009] S41. The worker places the polishing rod 5 of the polisher on the inner side surface of the lower end of the right arc-shaped aluminum piece 3, as shown in Figure 3 Then, the worker moves the polisher along the arc length of the arc-shaped aluminum piece 3. In the moving process, the polishing rod 5 gradually polishes the burrs on the inner side surface of the arc-shaped aluminum piece 3. When the polishing rod 5 moves to the inner end surface of the upper end of the right arc-shaped aluminum piece 3, as shown in Figure 4As shown, the burrs on the inner side of the right arc-shaped aluminum piece 3 are all polished off;

[0010] S42, the worker moves the polisher horizontally to the right, and the polishing rod 5 gradually polishes off the burrs on the inner side of the horizontal aluminum piece 4; when the polishing rod 5 moves to the inner end face of the right end of the right horizontal aluminum piece 4, as shown in Figure 5 As shown, the burrs on the inner side of the right horizontal aluminum piece 4 are all polished off;

[0011] S43, the worker places the polishing rod 5 of the polisher on the outer side of the lower end of the right arc-shaped aluminum piece 3, as shown in Figure 6 Then, the worker moves the polisher along the arc length of the arc-shaped aluminum piece 3, and in the process of moving, the polishing rod 5 gradually polishes off the burrs on the outer side of the arc-shaped aluminum piece 3; when the polishing rod 5 moves to the outer side of the upper end of the right arc-shaped aluminum piece 3, as shown in Figure 7 As shown, the burrs on the outer side of the right arc-shaped aluminum piece 3 are all polished off;

[0012] S44, the worker moves the polisher horizontally to the right, and the polishing rod 5 gradually polishes off the burrs on the outer side of the right horizontal aluminum piece 4; when the polishing rod 5 moves to the outer side of the right end of the right horizontal aluminum piece 4, as shown in Figure 8 As shown, the burrs on the outer side of the right horizontal aluminum piece 4 are all polished off, and thus the burrs on the inner and outer sides of the right arc-shaped aluminum piece 3 and the right horizontal aluminum piece 4 are finally polished off;

[0013] S5, the worker repeats the operation of step S4 once, and thus the burrs on the inner and outer sides of the left arc-shaped aluminum piece 3 and the left horizontal aluminum piece 4 are polished off, so that the burrs on one special-shaped aluminum profile are finally polished off;

[0014] S6, the worker repeats the operations of steps S1-S5 multiple times, and thus the burrs on a batch of special-shaped aluminum profiles are polished off.

[0015] However, although the method used in the prior art can polish off the burrs on the special-shaped aluminum profile, the following technical defects are still found in actual operation:

[0016] I, in step S4, the worker needs to move the polisher four times to polish off the burrs on the inner and outer end faces of the right arc-shaped aluminum piece 3 and the right horizontal aluminum piece 4; in step S5, the worker also needs to move the polisher four times to polish off the burrs on the inner and outer end faces of the left arc-shaped aluminum piece 3 and the left horizontal aluminum piece 4, that is, a total of eight processes are needed to polish off the burrs on one special-shaped aluminum profile, which causes a long time to complete the polishing of one special-shaped aluminum profile, and thus a long time is needed to polish a batch of special-shaped aluminum profiles, thereby reducing the polishing efficiency of the special-shaped aluminum profile.

[0017] II. When the grinding rod 5 is grinding the arc-shaped aluminum part 3, the grinding force generated during the grinding process will cause the arc-shaped aluminum part 3 to bend and deform inward. However, the process requires that after the burrs on the inner and outer sides of the arc-shaped aluminum part 3 are ground off, the arc-shaped aluminum part 3 should not be deformed at all, thus reducing the grinding quality of the irregular aluminum profile.

[0018] Therefore, there is an urgent need for a grinding device and method that can greatly improve the grinding efficiency and grinding quality of irregular aluminum profiles. Summary of the Invention

[0019] The purpose of this invention is to overcome the shortcomings of the prior art and provide a grinding device and method for irregular aluminum profiles that greatly improves the grinding efficiency and grinding quality of irregular aluminum profiles.

[0020] The objective of this invention is achieved through the following technical solution: a grinding device for irregular aluminum profiles, comprising a fixture set on a machine base for positioning and fixing the irregular aluminum profiles, a gantry frame set on the machine base directly above the fixture, a horizontally arranged bidirectional hydraulic cylinder fixed on the bottom surface of the gantry frame beam, a grinding component A for grinding off the inner and outer burrs of the right arc-shaped aluminum part and the right horizontal aluminum part of the irregular aluminum profile on the right piston rod of the bidirectional hydraulic cylinder, and a grinding component B for grinding off the inner and outer burrs of the right arc-shaped aluminum part and the right horizontal aluminum part of the irregular aluminum profile on the left piston rod of the bidirectional hydraulic cylinder;

[0021] The grinding assembly A includes a connecting shaft fixed to the right piston rod of the bidirectional cylinder and an L-plate fixed to the right end of the connecting shaft. A hinge seat and a feed cylinder are fixed on the top surface of the horizontal part of the L-plate. A vertical plate is hinged to the hinge seat via a pin. A frame is fixed to the top of the vertical plate. A first grinding rod and a second grinding rod are rotatably mounted in the frame via a rotating shaft. The vertical distance between the bottom surface of the first grinding rod and the top surface of the second grinding rod is equal to the thickness of the horizontal aluminum part. A first servo motor and a second servo motor are fixed in the frame. The output shaft of the first servo motor is connected to the rotating shaft of the first grinding rod, and the output shaft of the second servo motor is connected to the rotating shaft of the second grinding rod. A downwardly inclined support plate is fixed on the right side wall of the vertical plate. A connecting rod is hinged between the support plate and the working end of the piston rod of the feed cylinder.

[0022] An arched frame is fixed on the left end face of the vertical part of the L plate, located directly above the feed cylinder. A clamping cylinder is fixed on the side wall of the arched frame, with the clamping head of the clamping cylinder facing the area enclosed by the first grinding rod and the second grinding rod.

[0023] Multiple support legs, which are fixed to the ground, are mounted on the bottom surface of the machine.

[0024] The fixture includes a platform fixed to the machine base and a clamping seat fixed to the top surface of the platform. A clamping groove is formed on the top surface of the clamping seat, and the longitudinal width of the clamping groove is equal to the longitudinal width of the hollow rectangular aluminum tube of the shaped aluminum profile. Locking cylinders are located on the top surface of the platform and on the left and right sides of the clamping seat. The piston rods of the two locking cylinders extend outward, and each extension end is fixed with an upwardly extending locking plate. The extension ends of the two locking plates are opposite to the clamping groove of the clamping seat.

[0025] The grinding assembly A and grinding assembly B are symmetrical about the cylinder body of the bidirectional hydraulic cylinder.

[0026] An upper mounting bracket is fixed inside the frame and on its top wall, and the first grinding rod is rotatably mounted inside the upper mounting bracket; a lower mounting bracket is fixed inside the frame and on its bottom wall, and the second grinding rod is rotatably mounted inside the lower mounting bracket.

[0027] A horizontally arranged guide rail is fixed on the bottom surface of the gantry beam, and a sliding block is fixed on the top surface of the vertical part of the L plate, with the sliding block slidably mounted on the guide rail.

[0028] The grinding device also includes a controller, which is electrically connected to the bidirectional hydraulic cylinder, the feed hydraulic cylinder, the clamping hydraulic cylinder, the locking hydraulic cylinder, the first servo motor, and the second servo motor via signal lines.

[0029] A grinding method for irregularly shaped aluminum profiles, comprising the following steps:

[0030] S1. The specific steps for positioning and fixing the first irregular aluminum profile are as follows:

[0031] S11. The worker takes out an irregularly shaped aluminum profile;

[0032] S12. Insert the hollow rectangular aluminum tube of the irregular aluminum profile into the slot of the card seat from top to bottom. At this time, the hollow rectangular aluminum tube is just between the two locking plates of the clamp.

[0033] S13. The piston rods of both locking cylinders of the control fixture retract, and the piston rods drive the locking plates to move towards the hollow rectangular aluminum tube. When the piston rods of both locking cylinders are fully retracted, the hollow rectangular aluminum tube is just fixed between the two locking plates, thus finally realizing the positioning and fixing of the irregular aluminum profile. At this time, the inner side of the right horizontal aluminum part of the irregular aluminum profile is flush with the top surface of the second grinding rod of the grinding component A, and the outer side of the right horizontal aluminum part is flush with the bottom surface of the first grinding rod of the grinding component A; at the same time, the inner side of the left horizontal aluminum part of the irregular aluminum profile is flush with the top surface of the second grinding rod of the grinding component B, and the outer side of the left horizontal aluminum part is flush with the bottom surface of the first grinding rod of the grinding component B.

[0034] S2. The first servo motor and the second servo motor of the grinding component A and the grinding component B are both started. The first servo motor drives the first grinding rod to rotate around its own axis. At the same time, the second servo motor drives the second grinding rod to rotate around its own axis.

[0035] S3. Control both piston rods of the bidirectional hydraulic cylinder to retract. The right piston rod drives the grinding assembly A to move linearly to the left, while the left piston rod drives the grinding assembly B to move linearly to the right. When the piston rods of the bidirectional hydraulic cylinder retract to the set distance, the second grinding rod and the first grinding rod of the grinding assembly A grind the inner and outer sides of the right end of the right horizontal aluminum part, respectively; at the same time, the second grinding rod and the first grinding rod of the grinding assembly B grind the inner and outer sides of the left end of the left horizontal aluminum part, respectively.

[0036] As the two piston rods of the double-acting cylinder continue to retract, the second grinding rod of grinding component A gradually grinds away the burrs on the inner side of the right horizontal aluminum part, and the first grinding rod of grinding component A gradually grinds away the burrs on the outer side of the right horizontal aluminum part; at the same time, the second grinding rod of grinding component B gradually grinds away the burrs on the inner side of the left horizontal aluminum part, and the first grinding rod of grinding component B gradually grinds away the burrs on the outer side of the left horizontal aluminum part.

[0037] When the two piston rods of the double-acting cylinder are fully retracted, the grinding component A grinds away the burrs on the inner and outer sides of the right horizontal aluminum part of the irregular aluminum profile, and the axis of the pin of the grinding component A coincides with the center of the right arc-shaped aluminum part, and the chuck of the clamping cylinder fits onto the outside of the right horizontal aluminum part; at the same time, the grinding component B grinds away the burrs on the inner and outer sides of the left horizontal aluminum part of the irregular aluminum profile, and the axis of the pin of the grinding component B coincides with the center of the left arc-shaped aluminum part, and the chuck of the clamping cylinder fits onto the outside of the left horizontal aluminum part.

[0038] S4. Control the start of the clamping cylinder of the grinding component A, and the clamping cylinder chuck clamps and fixes the horizontal aluminum part on the right side; at the same time, control the start of the clamping cylinder of the grinding component B, and the clamping cylinder chuck clamps and fixes the horizontal aluminum part on the left side.

[0039] S5. The worker controls the piston rod of the feed cylinder of the grinding component A to extend to the left. The piston rod drives the connecting rod to move to the left. The connecting rod drives the support plate to rotate counterclockwise around the axis of the pin. The support plate drives the frame to rotate synchronously. The frame drives the second grinding rod and the first grinding rod to move along the inner and outer sides of the right arc-shaped aluminum part, respectively. The second grinding rod gradually grinds away the burrs on the inner side of the right arc-shaped aluminum part, and the first grinding rod gradually grinds away the burrs on the outer side of the right arc-shaped aluminum part.

[0040] At the same time, the piston rod of the feed cylinder of the grinding component B extends to the right, thereby causing the frame to drive the second grinding rod and the first grinding rod to move along the inner and outer sides of the left arc-shaped aluminum part, respectively. The second grinding rod gradually grinds away the burrs on the inner side of the left arc-shaped aluminum part, and the first grinding rod gradually grinds away the burrs on the outer side of the left arc-shaped aluminum part.

[0041] When the piston rod of the feed cylinder of grinding component A is fully extended, grinding component A just grinds away the burrs on the inner and outer sides of the right arc-shaped aluminum part of the irregular aluminum profile; at the same time, when the piston rod of the feed cylinder of grinding component B is fully extended, grinding component B just grinds away the burrs on the inner and outer sides of the left arc-shaped aluminum part of the irregular aluminum profile, thus finally achieving the goal of grinding away the burrs on an irregular aluminum profile.

[0042] S6. The specific steps for removing the polished irregular-shaped aluminum profile are as follows:

[0043] S61. The worker controls the first and second servo motors of grinding components A and B to be turned off, and the first and second grinding rods stop rotating; the worker also controls the clamping cylinder to be turned off, and the clamping cylinder chuck no longer clamps the horizontal aluminum part.

[0044] S62. Control the piston rods of the feed cylinders of grinding assembly A and grinding assembly B to retract, and then control the two piston rods of the bidirectional cylinder to extend outward, so that grinding assembly A and grinding assembly B are reset.

[0045] S63. The piston rods of the two locking cylinders of the control fixture extend outward, and the piston rods drive the locking plates to move outward, so that the irregular aluminum profile is no longer fixed by the two locking plates; then the worker removes the polished irregular aluminum profile from the holder.

[0046] S7. Workers can repeat steps S1 to S6 multiple times to remove burrs from a batch of irregularly shaped aluminum profiles.

[0047] The present invention has the following advantages: it greatly improves the grinding efficiency of irregular aluminum profiles and greatly improves the grinding quality of irregular aluminum profiles. Attached Figure Description

[0081] The grinding assembly A10 includes a connecting shaft 12 fixed to the piston rod on the right side of the bidirectional cylinder 9, and an L-plate 13 fixed to the right end of the connecting shaft 12.

A frame 18 is fixed to the top of the vertical plate 17. A first grinding rod 19 and a second grinding rod 20 are rotatably mounted in the frame 18 via a rotating shaft. The vertical distance between the bottom surface of the first grinding rod 19 and the top surface of the second grinding rod 20 is equal to the thickness of the horizontal aluminum part 4. A first servo motor 21 and a second servo motor are fixed in the frame 18. The output shaft of the first servo motor 21 is connected to the rotating shaft of the first grinding rod 19, and the output shaft of the second servo motor 22 is connected to the rotating shaft of the second grinding rod 20.

[0085] A grinding method for irregularly shaped aluminum profiles, comprising the following steps:

[0086] S1. The specific steps for positioning and fixing the first irregular aluminum profile are as follows:

[0087] S11, The worker takes out a... Figures 1-2 The irregularly shaped aluminum profile shown;

[0088] S12. Insert the hollow rectangular aluminum tube 1 of the irregular aluminum profile into the slot 30 of the card holder 29 from top to bottom, such as... Figure 17 As shown, at this time, the hollow rectangular aluminum tube 1 is exactly between the two locking plates 32 of the clamp 7;

[0089] S13, the piston rods of both locking cylinders 31 of the control fixture 7 retract, and the piston rods drive the locking plate 32 to move towards the hollow rectangular aluminum tube 1. When the piston rods of both locking cylinders 31 are fully retracted, the hollow rectangular aluminum tube 1 is just fixed between the two locking plates 32, thus finally realizing the positioning and fixing of the irregular aluminum profile. Figure 18As shown, at this time, the inner surface of the right horizontal aluminum part 4 of the irregular aluminum profile is flush with the top surface of the second grinding rod 20 of the grinding assembly A10, and the outer surface of the right horizontal aluminum part 4 is flush with the bottom surface of the first grinding rod 19 of the grinding assembly A10; at the same time, the inner surface of the left horizontal aluminum part 4 of the irregular aluminum profile is flush with the top surface of the second grinding rod 20 of the grinding assembly B11, and the outer surface of the left horizontal aluminum part 4 is flush with the bottom surface of the first grinding rod 19 of the grinding assembly B11.

[0090] S2. The first servo motor 21 and the second servo motor 22 of the control polishing assembly A10 and polishing assembly B11 are both started. The first servo motor 21 drives the first polishing rod 19 to rotate around its own axis. At the same time, the second servo motor 22 drives the second polishing rod 20 to rotate around its own axis.

[0091] S3. Both piston rods of the bidirectional hydraulic cylinder 9 retract. The right piston rod drives the grinding assembly A10 to move linearly to the left, while the left piston rod drives the grinding assembly B11 to move linearly to the right. When the piston rods of the bidirectional hydraulic cylinder 9 retract to the set distance, the second grinding rod 20 and the first grinding rod 19 of the grinding assembly A10 grind the inner and outer sides of the right end of the right horizontal aluminum part 4, respectively. Figure 19 As shown; simultaneously, the second polishing rod 20 and the first polishing rod 19 of the polishing assembly B11 polish the inner and outer sides of the left end of the left horizontal aluminum part 4, respectively, as shown. Figure 19 As shown;

[0092] As the two piston rods of the bidirectional hydraulic cylinder 9 continue to retract, the second grinding rod 20 of the grinding assembly A10 gradually grinds away the burrs on the inner side of the right-side horizontal aluminum part 4, such as... Figure 20 As shown, the first grinding rod 19 of grinding assembly A10 gradually grinds away the burrs on the outer surface of the right horizontal aluminum part 4; simultaneously, the second grinding rod 20 of grinding assembly B11 gradually grinds away the burrs on the inner surface of the left horizontal aluminum part 4, and the first grinding rod 19 of grinding assembly B11 gradually grinds away the burrs on the outer surface of the left horizontal aluminum part 4, as shown. Figure 20 As shown;

[0093] After the two piston rods of the double-acting hydraulic cylinder 9 are fully retracted, the grinding assembly A10 grinds away the burrs on the inner and outer sides of the right-side horizontal aluminum part 4 of the irregular aluminum profile, such as... Figure 21 As shown, the axis of the pin 16 of the grinding component A10 coincides with the center of the arc-shaped aluminum part 3 on the right, and the chuck 27 of the clamping cylinder 26 fits perfectly over the outside of the horizontal aluminum part 4 on the right; at the same time, the grinding component B11 grinds away the burrs on the inner and outer sides of the horizontal aluminum part 4 on the left side of the irregular aluminum profile, such as... Figure 21As shown, the axis of the pin 16 of the grinding component B11 coincides with the center of the arc-shaped aluminum part 3 on the left, and the chuck 27 of the clamping cylinder 26 fits just outside the horizontal aluminum part 4 on the left.

[0094] S4. The clamping cylinder 26 of the control grinding assembly A10 is activated, and the chuck 27 of the clamping cylinder 26 clamps and fixes the horizontal aluminum part 4 on the right side. Figure 22 As shown; simultaneously, the clamping cylinder 26 of the control grinding assembly B11 is activated, and the chuck 27 of the clamping cylinder 26 clamps and fixes the horizontal aluminum part 4 on the left side, as shown. Figure 22 As shown;

[0095] S5. The worker controls the piston rod of the feed cylinder 15 of the grinding assembly A10 to extend to the left. The piston rod drives the connecting rod 24 to move to the left. The connecting rod 24 drives the support plate 23 to rotate counterclockwise around the axis of the pin 16. The support plate 23 drives the frame 18 to rotate synchronously. The frame 18 drives the second grinding rod 20 and the first grinding rod 19 to move along the inner and outer sides of the right arc-shaped aluminum part 3, respectively. The second grinding rod 20 gradually grinds away the burrs on the inner side of the right arc-shaped aluminum part 3, and the first grinding rod 19 gradually grinds away the burrs on the outer side of the right arc-shaped aluminum part 3. Figure 23 As shown;

[0096] Simultaneously, the piston rod of the feed cylinder 15 of the grinding assembly B11 extends to the right, causing the frame 18 to drive the second grinding rod 20 and the first grinding rod 19 to move along the inner and outer sides of the left arc-shaped aluminum part 3, respectively. The second grinding rod 20 gradually grinds away the burrs on the inner side of the left arc-shaped aluminum part 3, and the first grinding rod 19 gradually grinds away the burrs on the outer side of the left arc-shaped aluminum part 3. Figure 23 As shown;

[0097] When the piston rod of the feed cylinder 15 of the grinding assembly A10 is fully extended, the grinding assembly A10 just grinds away the burrs on the inner and outer sides of the right-side curved aluminum part 3 of the irregular aluminum profile, such as... Figure 24 As shown; simultaneously, when the piston rod of the feed cylinder 15 of the grinding assembly B11 is fully extended, the grinding assembly B11 just grinds away the burrs on the inner and outer sides of the left curved aluminum part 3 of the irregular aluminum profile, as shown. Figure 24 As shown, this ultimately achieved the goal of grinding away the burrs on an irregularly shaped aluminum profile;

[0098] In steps S4-S5, it is known that because the horizontal aluminum part 4 of the right-side arc-shaped aluminum part 3 is clamped and fixed in the chuck 27 of the clamping cylinder 26 of the grinding assembly A10, and the horizontal aluminum part 4 of the left-side arc-shaped aluminum part 3 is clamped and fixed in the chuck 27 of the grinding assembly B11, the arc-shaped aluminum part 3 is firmly stabilized. Therefore, when the first grinding rod 19 and the second grinding rod 20 of the grinding assembly A10 grind the right-side arc-shaped aluminum part 3, the right-side arc-shaped aluminum part 3 will not bend or deform inward. At the same time, when the first grinding rod 19 and the second grinding rod 20 of the grinding assembly B11 grind the left-side arc-shaped aluminum part 3, the left-side arc-shaped aluminum part 3 will not bend or deform inward, thus effectively protecting the arc-shaped aluminum part 3. Therefore, this grinding device, compared to... Figures 3-8 The grinding method shown greatly improves the grinding quality of irregularly shaped aluminum profiles.

[0099] S6. The specific steps for removing the polished irregular-shaped aluminum profile are as follows:

[0100] S61, the worker controls the first servo motor 21 and the second servo motor 22 of the grinding assembly A10 and the grinding assembly B11 to be turned off, the first grinding rod 19 and the second grinding rod 20 to stop rotating; the control clamping cylinder 26 is turned off, and the chuck 27 of the clamping cylinder 26 no longer clamps the horizontal aluminum part 4.

[0101] S62. Control the piston rods of the feed cylinders 15 of the grinding assembly A10 and the grinding assembly B11 to retract, and then control the two piston rods of the bidirectional cylinder 9 to extend outward, so that the grinding assembly A10 and the grinding assembly B11 are reset.

[0102] S63, the piston rods of the two locking cylinders 31 of the control fixture 7 extend outwards, and the piston rods drive the locking plate 32 to move outwards, so that the irregular aluminum profile is no longer fixed by the two locking plates 32; then the worker removes the polished irregular aluminum profile from the holder 29, in the following direction. Figure 25 As indicated by the middle arrow;

[0103] S7. Workers can repeat steps S1 to S6 multiple times to remove burrs from a batch of irregularly shaped aluminum profiles.

[0104] Furthermore, as can be seen from steps S3 to S5, the worker only needs to control both piston rods of the bidirectional cylinder 9 to retract, thereby using grinding components A10 and B11 to grind away the burrs on the inner and outer sides of the right horizontal aluminum part 4 and the left horizontal aluminum part 4 respectively; then, by controlling the piston rods of the feed cylinder 15 of grinding components A10 and B11 to extend, the burrs on the inner and outer sides of the two arc-shaped aluminum parts 3 can be ground away respectively, and finally the burrs on the irregular aluminum profile can be ground away.

[0105] Therefore, this grinding device only requires two steps to remove burrs from irregularly shaped aluminum profiles in one go, compared to... Figures 3-8 The grinding method shown eliminates the need for eight steps to remove burrs from a single irregular aluminum profile, thus enabling the grinding of a single irregular aluminum profile to be completed in a short time. Consequently, it allows for the grinding of a batch of irregular aluminum profiles to be completed in a short time, thereby greatly improving the grinding efficiency of irregular aluminum profiles.
