Description

Technical Field

[0001] The present invention relates to a polishing device, and particularly to a surface polishing device for aluminum alloy plates. Background Art

[0002] Polishing refers to a processing method that uses mechanical, chemical, or electrochemical actions to reduce the surface roughness of a workpiece to obtain a bright and flat surface, and is a finishing process that uses a polishing tool and abrasive particles or other polishing media to process the surface of the workpiece.

[0003] Currently, most of the polishing operations on aluminum alloy plates are carried out using a polishing machine. However, the shapes of aluminum alloy plates on the market are diverse. The current polishing machines are only suitable for some flat aluminum alloy plates and are not convenient for polishing the concave parts of some aluminum alloy plates. Generally, workers use a small polishing wheel to polish the two sides and the bottom of the concave part of the aluminum alloy plate. However, workers cannot stabilize the polishing wheel and the aluminum alloy plate at the same time, and it is easy for the position of the polishing wheel or the aluminum alloy plate to shift, resulting in inconsistent flatness of the polished aluminum alloy plate and affecting the polishing quality. Summary of the Invention

An L-shaped sliding rod is slidably connected to one side of the sliding support close to the fixed long rod. The L-shaped sliding rod contacts the fixed groove plate. A lifting spring is connected between the L-shaped sliding rod and the sliding support. A fixed round rod is fixedly connected to one side of the sliding support close to the fixed groove plate. The fixed round rod contacts the fixed groove plate. A fixed bracket is fixedly connected to the side of the fixed groove plate far from the fixed long rod. A trapezoidal long plate is fixedly connected to one side of the fixed bracket close to the fixed groove plate.

[0008] As a preferred technical solution of the present invention, the side limiting mechanism includes special-shaped limiting strips, tension springs and fixed L-shaped round rods. Two special-shaped limiting strips are slidably connected to each of the two sliding bases. Tension springs are connected between the sliding bases and the special-shaped limiting strips. Fixed L-shaped round rods are fixedly connected to both sides of several convex blocks of the convex bottom plate. The special-shaped limiting strips and the fixed L-shaped round rods are on the same horizontal line.

[0009] As a preferred technical solution of the present invention, a locking mechanism is further included. The locking mechanism is arranged on the fixed groove plate. The locking mechanism includes a fixed T-shaped block, a wedge-shaped groove strip, a return spring, a locking round rod and a compression spring.

[0012] Beneficial effects:

[0013] 1. Workers push the sliding base and the fixed groove plate to move, so that the special-shaped limit strips on both sides contact the two sides of the aluminum alloy plate, limit the aluminum alloy plate, and prevent the aluminum alloy plate from shaking, so as to more stably polish the aluminum alloy plate subsequently; the drive motor will drive the polishing wheel to rotate at a high speed, and the servo motor will drive the polishing wheel to move left and right, so that the polishing wheel moves left and right and rotates at a high speed to quickly polish the two sides and the bottom of the concave part of the aluminum alloy plate.

[0014] 2. When workers push the hand lever and the sliding base to move, the locking round rod will be stuck into one of the card slots of the fixed guide groove frame, thereby limiting the sliding base and the fixed groove plate, so that the sliding base and the fixed groove plate no longer move. This can prevent the sliding base and the fixed groove plate from shaking and causing the polishing wheel to shift during the polishing of the aluminum alloy plate by the polishing wheel, and thus can stably polish the aluminum alloy plate.

[0015] 3. The movement of the sliding base and the fixed groove plate will drive the pressing wheel to move, so that the pressing wheel contacts the top of the aluminum alloy plate. Under the elastic force of the torsion spring, the pressing wheel will closely adhere to the top of the aluminum alloy plate to further limit the aluminum alloy plate, and prevent the aluminum alloy plate from shaking due to the vibration generated when the polishing wheel polishes the aluminum alloy plate, which may cause the position of the aluminum alloy plate to shift, so that the polishing wheel can more stably polish the aluminum alloy plate.

Detailed implementation manners

[0031] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0032] Embodiment 1

[0033] A surface polishing device for an aluminum alloy plate, as Figures 1-11 shown, includes a convex bottom plate 1, a fixed guide groove frame 2, a sliding base 4, sliding wheels 41, a fixed groove plate 5, a hand lever 6, a reciprocating movement mechanism, a lifting mechanism and a side limiting mechanism. A plurality of convex blocks are welded on the convex bottom plate 1. Two fixed guide groove frames 2 are welded on the upper side of the convex bottom plate 1. The two fixed guide groove frames 2 are symmetrically arranged. An aluminum alloy plate 3 is placed on the top of the convex bottom plate 1. Two sliding bases 4 are slidably connected to the two fixed guide groove frames 2. A plurality of sliding wheels 41 are rotatably connected to the bottom of the two sliding bases 4. The sliding wheels 41 are used to reduce the friction between the sliding base 4 and the convex bottom plate 1. A fixed groove plate 5 is welded between the tops of the two sliding bases 4. Hand levers 6 are welded on both sides of the fixed groove plate 5. The two hand levers 6 are symmetrically arranged. The reciprocating movement mechanism is arranged on the fixed groove plate 5 and is used to polish the aluminum alloy plate 3. The lifting mechanism is arranged on the reciprocating movement mechanism and is connected to the fixed groove plate 5 and is used to polish the aluminum alloy plate 3. The side limiting mechanism is arranged on the sliding base 4 and is connected to the convex bottom plate 1 and is used to limit the aluminum alloy plate 3.

[0034] The reciprocating movement mechanism includes a fixed long rod 71, a sliding support 72, a servo motor 73, a fixed reciprocating lead screw 74, a sliding block 75, a driving motor 76, a power shaft 77, and a polishing wheel 78. The fixed long rod 71 is welded to the fixed groove plate 5. The fixed long rod 71 is horizontally arranged. A sliding support 72 is slidably connected between the fixed groove plate 5 and the fixed long rod 71. One end of the fixed groove plate 5 close to the sliding support 72 is bolted with a servo motor 73. A fixed reciprocating lead screw 74 is fixedly connected to the output shaft of the servo motor 73. The fixed reciprocating lead screw 74 is horizontally arranged. The side of the fixed groove plate 5 away from the servo motor 73 is rotatably connected to the fixed reciprocating lead screw 74. One end of the fixed reciprocating lead screw 74 close to the servo motor 73 is threadedly connected with a sliding block 75. The sliding block 75 is slidably connected to the sliding support 72. A driving motor 76 is bolted to the sliding support 72. A power shaft 77 is fixedly connected to the output shaft of the driving motor 76. The power shaft 77 is vertically arranged. The power shaft 77 is rotatably connected to the sliding support 72. One end of the power shaft 77 away from the servo motor 73 is fixedly connected with a polishing wheel 78. The polishing wheel 78 is used for polishing the aluminum alloy plate 3.

[0035] The lifting mechanism includes an L-shaped sliding rod 81, a lifting spring 82, a fixed round rod 83, a fixed bracket 84, and a trapezoidal long plate 85. An L-shaped sliding rod 81 is slidably connected to one side of the sliding support 72 close to the fixed long rod 71. The L-shaped sliding rod 81 is of an L-shaped structure. The L-shaped sliding rod 81 contacts the fixed groove plate 5. A lifting spring 82 is connected between the L-shaped sliding rod 81 and the sliding support 72. The lifting spring 82 is sleeved on the L-shaped sliding rod 81. A fixed round rod 83 is welded to one side of the sliding support 72 close to the fixed groove plate 5. The fixed round rod 83 is horizontally arranged. The fixed round rod 83 is used to support the sliding support 72. The fixed round rod 83 contacts the fixed groove plate 5. A fixed bracket 84 is welded to the side of the fixed groove plate 5 away from the fixed long rod 71. A trapezoidal long plate 85 is welded to one side of the fixed bracket 84 close to the fixed groove plate 5. The trapezoidal long plate 85 is used to limit the fixed round rod 83.

[0036] The side limiting mechanism includes special-shaped limiting strips 91, tension springs 92, and fixed L-shaped round rods 93. Two special-shaped limiting strips 91 are slidably connected to each of the two sliding bases 4. The special-shaped limiting strips 91 are used to limit the aluminum alloy plate 3. Tension springs 92 are connected between the sliding bases 4 and the special-shaped limiting strips 91 by hooks. The tension springs 92 are sleeved on the special-shaped limiting strips 91. Fixed L-shaped round rods 93 are welded to both sides of several convex blocks of the convex bottom plate 1. The fixed L-shaped round rods 93 are of an L-shaped structure. The special-shaped limiting strips 91 and the fixed L-shaped round rods 93 are on the same horizontal line.

[0037] When it is necessary to polish the concave part of the aluminum alloy plate 3, the worker places the aluminum alloy plate 3 on the concave block of the convex bottom plate 1, so that the aluminum alloy plate 3 fits into the convex block of the convex bottom plate 1, and the convex block of the convex bottom plate 1 will limit the aluminum alloy plate 3, and then starts the drive motor 76 and adjusts the output shaft of the motor to rotate at high speed. The high-speed rotation of the output shaft of the drive motor 76 will drive the power shaft 77 to rotate forward at high speed, and the high-speed forward rotation of the power shaft 77 will drive the polishing wheel 78 to rotate at high speed. Then the worker pushes the hand rod 6 to move along the fixed guide groove frame 2. The movement of the hand rod 6 will drive the two sliding bases 4 and the fixed groove plate 5 to move along the fixed guide groove frame 2. Several sliding wheels 41 will rotate with the sliding base 4. The movement of the two sliding bases 4 will drive the special-shaped limit strips 91 on both sides to move. When the special-shaped limit strips 91 on both sides move, they will contact the fixed L-shaped round rods 93 on both sides of one of the protrusions of the convex bottom plate 1. When the special-shaped limit strips 91 on both sides continue to move, they will be squeezed by the fixed L-shaped round rods 93 on both sides and move in the direction of approaching each other. The tension spring 92 is stretched, and the special-shaped limit strips 91 on both sides move in the direction of approaching each other and contact the two sides of the aluminum alloy plate 3, and limit the aluminum alloy plate 3, so that the aluminum alloy plate 3 can be polished more stably later. When the polishing wheel 78 moves to one of the recesses of the aluminum alloy plate 3, the worker stops pushing the hand rod 6, so that the sliding base 4 and the fixed slot plate 5 stop moving, and then starts the servo motor 73. The rotation of the output shaft of the servo motor 73 drives the fixed reciprocating screw 74 to rotate, and the fixed reciprocating screw The rotation of 74 will drive the sliding block 75 and the sliding support 72 to move in the direction away from the servo motor 73. The movement of the sliding support 72 will move the driving motor 76, the power shaft 77, the polishing wheel 78, the L-shaped sliding rod 81, the lifting spring 82 and the fixed round rod 83. The movement of the fixed round rod 83 will disengage from the sliding special-shaped bar and contact the trapezoidal long plate 85. The L-shaped sliding rod 81 will be squeezed by the fixed groove plate 5 along the inclined surface of the top of the fixed groove plate 5 and move upward. However, since the trapezoidal long plate 85 limits the fixed round rod 83 at this time, and the fixed round rod 83 and the sliding support 72 are fixed, the L-shaped sliding rod 81 will not drive the sliding support 72 to move upward. The lifting spring 82 is stretched, and the movement of the polishing wheel 78 will be in contact with the aluminum alloy plate 3 and other parts. The polishing wheel 78 continues to move and rotates at a high speed to quickly polish the lower sides and bottom of one of the recesses in the aluminum alloy plate 3. The polishing wheel 78 continues to move and will lose contact with the aluminum alloy plate 3. At the same time, under the elastic force of the lifting spring 82, the fixed round rod 83 will move upward along the inclined surface of the trapezoidal long plate 85, thereby driving the polishing wheel 78 to move upward. When the sliding block 75 moves to the end of the fixed reciprocating screw rod 74, the fixed reciprocating screw rod 74 continues to rotate, which will drive the sliding block 75 and the sliding support 72 to move in the direction close to the servo motor 73, thereby driving the polishing wheel 78 and the fixed round rod 83 to move in the direction close to the servo motor 73. The fixed round rod 83 moves and will contact the trapezoidal long plate 85 again.The trapezoidal long plate 85 and the fixed groove plate 5 will limit the fixed round rod 83, thereby making the sliding support 72 more stable, avoiding the shaking of the lifting spring 82 and causing the polishing wheel 78 to shake. The movement of the polishing wheel 78 will contact the upper sides of one of the recesses of the aluminum alloy plate 3. The polishing wheel 78 continues to move and rotates at a high speed to quickly polish the upper sides of one of the recesses of the aluminum alloy plate 3. During this period, the worker needs to continue to hold the handle 6 in his hand to avoid the sliding base 4 and the fixed groove plate 5 shaking and affecting the polishing wheel 78 polishing the aluminum alloy The polishing wheel 78 continues to move toward the direction close to the servo motor 73 and will be out of contact with the aluminum alloy plate 3. The L-shaped sliding rod 81 continues to move toward the direction close to the servo motor 73 and will be out of contact with the top of the fixed slot plate 5. At this time, the fixed slot plate 5 no longer supports the L-shaped sliding rod 81. The fixed round rod 83 continues to move and will be out of contact with the trapezoidal long plate 85. The sliding support 72, the polishing wheel 78, the L-shaped sliding rod 81 and the fixed round rod 83 will move downward under the action of gravity. The L-shaped sliding rod 81 moves downward and is out of contact with the fixed slot plate 5. The top is re-contacted, and then the worker turns off the servo motor 73 and continues to push the hand rod 6 to move along the fixed guide groove frame 2, thereby driving the sliding base 4, the special-shaped limit strip 91 and the polishing wheel 78 to continue to move. The special-shaped limit strips 91 on both sides continue to move and will be out of contact with the fixed L-shaped round rods 93 on both sides of one of the protrusions of the convex bottom plate 1, and will be out of contact with the aluminum alloy plate 3. The reset of the tension spring 92 will drive the special-shaped limit strip 91 to reset. The special-shaped limit strips 91 on both sides continue to move and will be fixed on both sides of the next protrusion of the convex bottom plate 1. The fixed L-shaped round rods 93 come into contact with each other and are squeezed by the fixed L-shaped round rods 93 on both sides to move closer to each other. The tension spring 92 is compressed, and the special-shaped limit strips 91 on both sides move closer to each other, which will re-clamp the aluminum alloy plate 3 and limit the aluminum alloy plate 3. When the polishing wheel 78 moves to the next recessed area of the aluminum alloy plate 3, the worker starts the servo motor 73 again, allowing the polishing wheel 78 to move and polish the recessed area of the aluminum alloy plate 3. This process is repeated multiple times, and several recessed areas of the aluminum alloy plate 3 are quickly polished.

[0038] When the polishing of the several recesses of the aluminum alloy plate 3 is completed, the staff turns off the servo motor 73 and the drive motor 76, removes the aluminum alloy plate 3 from the convex bottom plate 1, and pushes the hand lever 6 and the sliding base 4 to reset together.

[0039] Example 2

[0040] On the basis of Example 1, Figure 9As shown, it further includes a locking mechanism. The locking mechanism is arranged on the fixed groove plate 5 and is used to clamp the sliding base 4 so that the sliding base 4 and the fixed groove plate 5 no longer move. This can prevent the sliding base 4 and the fixed groove plate 5 from shaking during the polishing of the aluminum alloy plate 3 by the polishing wheel 78, resulting in the deviation of the polishing wheel 78, and thus can stably polish the aluminum alloy plate 3. The locking mechanism includes a fixed T-shaped block 101, a wedge-shaped groove bar 102, a return spring 103, a locking round bar 104, and a compression spring 105. The fixed T-shaped block 101 is welded on the side of the fixed groove plate 5 away from the fixed long rod 71. The wedge-shaped groove bar 102 is slidably connected to the fixed T-shaped block 101. A return spring 103 is connected between the fixed T-shaped block 101 and the wedge-shaped groove bar 102. The return spring 103 is located inside the wedge-shaped groove bar 102. The locking round bar 104 is slidably connected to the side of the fixed groove plate 5 close to the servo motor 73. The locking round bar 104 is in an "L" shape and is used to lock the sliding base 4. The locking round bar 104 is vertically arranged. The bottom end of the locking round bar 104 contacts one of the fixed guide frames 2. A compression spring 105 is connected between the fixed groove plate 5 and the locking round bar 104. The compression spring 105 is sleeved on the locking round bar 104. The upper end of the locking round bar 104 is located above the wedge-shaped groove bar 102.

[0041] At first, since one of the fixed guide groove brackets 2 abuts against the locking round rod 104, the compression spring 105 is in a compressed state. When the worker pushes the hand lever 6 and the sliding base 4 to move along the fixed guide groove bracket 2, the movement of the fixed groove plate 5 will drive the fixed T-shaped block 101, the wedge-shaped groove bar 102, the return spring 103, the locking round rod 104 and the compression spring 105 to move together. When the locking round rod 104 moves above one of the card slots of the fixed guide groove bracket 2, the fixed guide groove bracket 2 no longer abuts against the locking round rod 104. The reset of the compression spring 105 will drive the locking round rod 104 to move downward and snap into one of the card slots of the fixed guide groove bracket 2, thereby limiting the sliding base 4 and the fixed groove plate 5, so that the sliding base 4 and the fixed groove plate 5 no longer move. This can prevent the sliding base 4 and the fixed groove plate 5 from shaking during the polishing of the aluminum alloy plate 3 by the polishing wheel 78, resulting in the deviation of the polishing wheel 78, and thus can stably polish the aluminum alloy plate 3. When the polishing wheel 78 finishes polishing one of the concave portions of the aluminum alloy plate 3, the movement of the fixed round rod 83 towards the servo motor 73 will contact the wedge-shaped groove bar 102. The continuous movement of the fixed round rod 83 will push the wedge-shaped groove bar 102 to move away from the fixed bracket 84, and the return spring 103 is compressed. The movement of the wedge-shaped groove bar 102 will contact the locking round rod 104 and push the locking round rod 104 to move upward, and the compression spring 105 is compressed. The upward movement of the locking round rod 104 will disengage from one of the card slots of the fixed guide groove bracket 2. Then, after the worker turns off the servo motor 73, the hand lever 6 and the sliding base 4 are pushed to continue moving along the fixed guide groove bracket 2, so that the locking round rod 104 snaps into the next card slot of the fixed guide groove bracket 2 to re-limit the sliding base 4; when all the concave portions of the aluminum alloy plate 3 are polished, the worker pulls the locking round rod 104 upward, the compression spring 105 is compressed, then the hand lever 6 and the sliding base 4 are pushed to reset, and then the locking round rod 104 is released, and one of the fixed guide groove brackets 2 abuts against the locking round rod 104.

[0042] Embodiment 3

[0043] Based on Embodiment 2, as Figures 12-13As shown, it also includes a fixed support frame 11, a fixed long round frame 12, a movable fan-shaped bar 13, an extrusion wheel 14 and a torsion spring 15. A fixed support frame 11 is welded between the upper side surfaces of the two sliding bases 4, and the fixed support frame 11 is in an "n" shape. The side of the fixed slot plate 5 close to the fixed long rod 71 and the side of the fixed support frame 11 away from the servo motor 73 are welded with a fixed long round frame 12, and the fixed long round frame 12 is in an "n" shape. Both sides of the two fixed long round frames 12 are rotatably connected with movable fan-shaped bars 13, and an extrusion wheel 14 is rotatably connected between the two movable fan-shaped bars 13. The extrusion wheel 14 is used to limit the aluminum alloy plate 3, and a torsion spring 15 is connected between the movable fan-shaped bar 13 and the fixed long round frame 12, and the torsion spring 15 is sleeved on the fixed long round frame 12.

[0044] At first, when the worker holds the hand lever 6 and pushes the two sliding bases 4 and the fixed groove plate 5 to move along the fixed guide groove frame 2, the movement of the two sliding bases 4 will drive the fixed support frame 11 to move, and the movement of the fixed support frame 11 and the fixed groove plate 5 will drive the two fixed long round frames 12 to move. The movement of the fixed long round frame 12 will drive the movable sector bar 13, the extrusion wheel 14 and the torsion spring 15 to move. The movement of the extrusion wheel 14 will contact the top of the aluminum alloy plate 3, and the extrusion wheel 14 will be squeezed and rotated by the aluminum alloy plate 3 as it continues to move. While the extrusion wheel 14 is squeezed by the aluminum alloy plate 3, it will drive the movable sector bar 13 to swing upward, and the torsion spring 15 will be twisted. At the same time, under the elastic force of the torsion spring 15, the extrusion wheel 14 will be close to the top of the aluminum alloy plate 3 for further limiting, so as to avoid the vibration of the polishing wheel 78 when polishing the aluminum alloy plate 3, which will cause the position of the aluminum alloy plate 3 to shift, so that the polishing wheel 78 can When the worker pushes the hand lever 6 and the sliding base 4 to reset, the reset of the two sliding bases 4 will drive the fixed support frame 11 to reset, and the reset of the fixed support frame 11 and the fixed groove plate 5 will drive the two fixed long round frames 12 to reset, and the reset of the fixed long round frame 12 will drive the movable fan bar 13, the extrusion wheel 14 and the torsion spring 15 to reset.

[0046] On the basis of Example 3, Figure 14As shown, it further includes a U-shaped frame 16 and a U-shaped sponge 17. The U-shaped frame 16 is welded on the sliding support 72. The U-shaped frame 16 is vertically arranged and has a "U" shape structure. The outer side of the U-shaped frame 16 is fixedly connected with the U-shaped sponge 17. The U-shaped sponge 17 is used to wipe the surface of the aluminum alloy plate. The U-shaped sponge 17 has a "U" shape structure.

[0047] At first, the U-shaped sponge 17 is wetted. When the sliding support 72 moves along the fixed reciprocating lead screw 74, it will drive the U-shaped frame 16 and the U-shaped sponge 17 to move together. The movement of the U-shaped sponge 17 will contact the two sides and the bottom of one of the concave parts of the aluminum alloy plate 3. When the U-shaped sponge 17 continues to move, it will wipe the two sides and the bottom of one of the concave parts of the aluminum alloy plate 3, removing the sundries in the concave part of the aluminum alloy plate 3 and preventing the particle impurities on the surface of the aluminum alloy plate 3 from affecting the polishing quality of the polishing wheel 78 on the aluminum alloy plate 3. When the sliding support 72 resets, it will drive the U-shaped frame 16 and the U-shaped sponge 17 to reset together. The movement of the sliding support 72 drives the U-shaped frame 16 to move at the notch of the groove of the aluminum alloy plate 3. The U-shaped frame 16 follows the movement of the sliding support 72 and drives the U-shaped sponge 17 to move together. The U-shaped sponge 17 contacts the notch of the groove of the aluminum alloy plate 3. When the U-shaped frame 16 continues to follow the movement of the sliding support 72, the inner side surface of the notch of the aluminum alloy plate 3 will squeeze the U-shaped sponge 17, causing the U-shaped sponge 17 to be compressed. When the U-shaped sponge 17 continues to move, it will first perform frictional cleaning on the inner side surface of the notch of the unpolished aluminum alloy plate 3, preventing the particle impurities on the surface of the aluminum alloy plate 3 from affecting the polishing quality of the polishing wheel 78 on the aluminum alloy plate 3. When the sliding support 72 moves to the end of the fixed reciprocating lead screw 74 and resets, the sliding support 72 drives the U-shaped frame 16 and the U-shaped sponge 17 to move together. The U-shaped sponge 17 wipes the inner side surface of the groove of the polished aluminum alloy plate 3, facilitating the cleaning of the remaining metal particles and improving the polishing quality of the polishing wheel 78 on the aluminum alloy plate 3.
