A grinding device and usage method for producing assembled doors

Abstract

The present invention relates to the field of polishing of assembled doors. The present invention discloses a polishing device for producing assembled doors and a method of use. The problem to be solved by the present invention is that during the polishing and polishing process of the wooden board, the surface of the solid wood is prone to bulges and other shapes. When polishing the bulges on the surface of the solid wood, after the polishing disc polishes off the bulges on the solid wood board, there is no way to stop in time. At this time, the polishing disc will polish the parts beside the bulges on the solid wood, which will cause wear on the parts beside the bulges, or cause the parts beside the bulges of the solid wood board to be uneven relative to the surface of the rest of the board, which will need to be repaired later, which will be time-consuming and labor-intensive. The present invention can effectively polish the bulges of the assembled board without contacting the rest of the bulges, thereby avoiding damage to the parts other than the bulges during the polishing process of the assembled board.

[0001] The present invention relates to the field of polishing of assembled doors, and in particular to a polishing device for producing assembled doors and a use method thereof. Background Art

[0002] Wood panels are made from whole pieces of wood. These panels are durable, have natural grain, and are an excellent choice for home renovations. However, these panels are expensive and are generally categorized by their specific nature, with no standardized specifications. Solid wood panels, on the other hand, are made from several smaller pieces of solid wood joined together using a specific method to create a single, larger piece.

[0003] The existing solid wood assembled doors are made of solid wood boards, and the solid wood boards need to be sanded and polished before assembly. During the sanding and polishing process, the surface of the solid wood is prone to bulges. When sanding the bulges on the surface of the solid wood, after the sanding disc sands off the bulges on the solid wood board, there is no way to stop in time. At this time, the sanding disc will sand the parts beside the bulge on the solid wood, which will cause wear on the parts beside the bulge, or cause the parts beside the bulge of the solid wood board to be uneven with respect to the surface of the rest of the board. Subsequent repairs will be required, which will be time-consuming and labor-intensive. Summary of the Invention

[0009] Preferably, the processing platform is also provided with a movable calibration device, and the movable calibration device includes a driving electric cylinder, a rotating frame, two connecting frames and two movable plates. The driving electric cylinder is fixedly arranged at the bottom of the processing platform, and the rotating frame is rotatably arranged on the processing platform. A dovetail groove is opened on the processing platform, and the two movable plates are symmetrically arranged on the processing platform, and the two movable plates slide in the dovetail groove. One end of the two connecting frames is respectively hinged to the two sides of the rotating frame, and the other end of the two connecting frames is respectively hinged to the two movable plates, and the telescopic end of the driving electric cylinder is connected to one of the movable plates.

[0010] Preferably, the tops of the two movable plates are provided with symmetrically arranged calibration parts, and the calibration parts include a base, a calibration frame, a tension spring and a blocking rod. The base is fixedly arranged on the top of the movable plate, and a receiving groove is provided on the base. The calibration frame is rotatably arranged in the receiving groove in the base, and legs extend on both sides of the calibration frame, and the angle between the two legs is 90 degrees. The two ends of the tension spring are respectively connected to the base and one of the legs, and the blocking rod is arranged in the receiving groove in the base and is located beside the other leg.

[0011] Preferably, the method for using the grinding equipment for producing assembled doors comprises the following steps:

[0012] S1: The operator places the assembled door panel to be polished on the processing platform, and then drives the electric cylinder to move one of the movable plates. The movement of one of the movable plates drives the rotating frame to rotate through the setting of the connecting frame. The rotation of the rotating frame drives the other connecting frame to move the other movable plate. At this time, the two movable plates move relative to each other and drive the two assembled door panels placed on the processing platform to move relative to each other. During the movement, the four sets of calibration parts will respectively conflict with the side corners of the two assembled door panels. When the movable plate contacts the calibration frame, the support angle connected to the tension spring will first contact the corners of the assembled plate, and then The two legs can then be used to clamp the angle of the assembled board, and the position of the assembled board can be adjusted so that the assembled board is gradually placed neatly, so that the grinding device can effectively contact the surface of the assembled board when grinding the assembled board. This arrangement eliminates the need for the operator to place the assembled board neatly when placing it on the processing platform, and the four sets of calibration parts can effectively fix the four corners of the assembled board, thereby avoiding the twisting of the assembled board during the grinding process, which affects the grinding work of the grinding plate.

[0013] S2: After the assembly board is limited by the mobile calibration device on the processing platform, the operator adjusts the position of the mobile frame to move the mobile frame on the carrier frame, and makes the grinding block at the bottom of the bearing sleeve contact the top surface of the assembly board. Then the driving motor drives the bearing sleeve to rotate. The bearing sleeve rotates to grind the surface of the assembly board through the set grinding block. The bearing frame can be driven to move by the screw slide so that the bearing sleeve can grind the surface of the assembly board as a whole, thereby completing the grinding work of the assembly board.

[0014] S3: When the screw slide drives the bearing sleeve to move and grind the assembly plate, when it encounters the protrusion on the assembly plate, the protrusion on the assembly plate will resist the grinding block, and the resistance rod corresponding to the protrusion will be driven to lift by the resistance, and after the resistance rod corresponding to the protrusion is lifted by the pressure of the protrusion, the resistance rod moves on the lower partition plate and the middle partition plate, which will pull the triangular connecting block to move on the fixed sleeve, and the movement of the triangular connecting block will drive the pull rod to move, and the sliding groove provided on the triangular connecting block will prevent the triangular connecting block from moving when it first moves, and the movement of the pull rod will pull the upper partition plate to move in the inner wall of the bearing sleeve. The upper partition is then used to lift up the interference rod of the part, and the interference rods of the other parts are lifted up so that the grinding block is no longer in contact with the surface of the assembly plate. At this time, only the part of the raised part of the assembly plate is in contact with the corresponding interference rod. By setting a pressure spring on the interference rod, the grinding block is only used to grind the raised part of the assembly plate, and the other positions are no longer in contact with the assembly plate. When the assembly plate is polished by this setting, the raised part of the assembly plate can be effectively polished without contacting the rest of the raised part, thereby avoiding damage to the parts other than the raised part during the polishing process of the assembly plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In the present invention, when the screw slide drives the bearing sleeve to move to grind the assembled plate, when it encounters the protrusion on the assembled plate, the protrusion on the assembled plate will interfere with the grinding block, and the interference rod corresponding to the protrusion will be driven to lift by the interference, and after the interference rod corresponding to the protrusion is lifted by the pressure of the protrusion, the interference rod moves on the lower partition plate and the middle partition plate, which will pull the triangular connecting block to move on the fixed sleeve, and the movement of the triangular connecting block will drive the pull rod to move, and the sliding groove provided on the triangular connecting block will prevent the triangular connecting block from moving when it first moves, and the movement of the pull rod will pull the upper partition plate to move in the inner wall of the bearing sleeve. , and then the upper partition plate is used to push up the interference rod of the part, and the interference rods of the other parts are pushed up so that the grinding block is no longer in contact with the surface of the assembly disk. At this time, only the part of the raised part of the assembly plate is in contact with the corresponding interference rod. By setting the pressure spring on the interference rod, the grinding block is only used to grind the raised part of the assembly plate, and the other positions are no longer in contact with the assembly plate. When the assembly plate is polished by this setting, the raised part of the assembly plate can be effectively polished without contacting the rest of the raised part, thereby avoiding damage to the parts other than the raised part during the polishing process of the assembly plate.

[0017] In the present invention, the operator places the assembled door panel to be polished on the processing platform, and then drives the electric cylinder to move one of the movable plates. The movement of one of the movable plates drives the rotating frame to rotate through the setting of the connecting frame, and the rotation of the rotating frame drives the other connecting frame to move the other movable plate. At this time, the two movable plates move relative to each other and drive the two assembled door panels placed on the processing platform to move relative to each other. During the movement, the four sets of calibration parts will respectively conflict with the side corners of the two assembled door panels. When the movable plate contacts the calibration frame, the support angle connected to the tension spring will first contact the edge corner of the assembled plate, and then When the plate comes into contact with the calibration frame, the calibration frame will deflect and the other leg of the calibration frame will move closer to the assembly plate. At this time, the angle formed by the two legs can clamp the angle of the assembly plate, and the position of the assembly plate can be adjusted so that the assembly plate is gradually placed neatly, so that the grinding device can effectively contact the surface of the assembly plate when grinding the assembly plate. This setting allows the operator to place the assembly plate neatly when placing it on the processing platform, and the four sets of calibration parts can effectively fix the four corners of the assembly plate, thereby avoiding the twisting of the assembly plate during the grinding process and affecting the grinding work of the grinding plate.

[0032] A moving part 4 is also provided at the top of each of the interference rods 31, and the moving part 4 includes a fixed sleeve 41, a triangular connecting block 42, a pull rod 43 and a fixed frame 44. The outer wall of the fixed sleeve 41 is fixedly connected to the inner wall of the bearing sleeve 23, and the fixed sleeve 41 at the top of each of the interference rods 31 is connected to the outer wall of the fixed sleeve 41 on the adjacent interference rod 31.

[0035] In this embodiment, Figure 1 、 Figure 7 、 Figure 8 and Figure 9 As shown, the processing platform 11 is further provided with a mobile calibration device 6, which includes a driving electric cylinder 61, a rotating frame 62, two connecting frames 63 and two movable plates 64. The driving electric cylinder 61 is fixedly arranged at the bottom of the processing platform 11, and the rotating frame 62 is rotatably arranged on the processing platform 11. A dovetail groove 12 is provided on the processing platform 11. The two movable plates 64 are symmetrically arranged on the processing platform 11, and the two movable plates 64 are slidably matched with the dovetail groove 12. One end of the two connecting frames 63 is respectively hinged to the two sides of the rotating frame 62, and the other end of the two connecting frames 63 is respectively hinged to the two movable plates 64. The telescopic end of the driving electric cylinder 61 is connected to one of the movable plates 64.

[0036] A symmetrically arranged calibration member 7 is provided on the top of each of the two movable plates 64. The calibration member 7 includes a base 71, a calibration frame 72, a tension spring 73 and a blocking rod 74. The base 71 is fixedly arranged on the top of the movable plate 64. A receiving groove 711 is provided on the base 71. The calibration frame 72 is rotatably arranged in the receiving groove 711 in the base 71. Legs extend on both sides of the calibration frame 72, and the angle between the two legs is 90 degrees. The two ends of the tension spring 73 are respectively connected to the base 71 and one of the legs. The blocking rod 74 is arranged in the receiving groove 711 in the base 71 and is located beside the other leg.

[0037] The operator places the assembled door panel to be polished on the processing platform 11, and then drives the electric cylinder 61 to move one of the movable plates 64. The movement of one of the movable plates 64 drives the rotating frame 62 to rotate through the setting of the connecting frame 63. The rotation of the rotating frame 62 drives the other connecting frame 63 to make the other movable plate 64 move. At this time, the two movable plates 64 move relative to each other and drive the two assembled door panels placed on the processing platform 11 to move relative to each other. During the movement, the four sets of calibration parts 7 will respectively conflict with the side corners of the two assembled door panels. When the movable plate 64 contacts the calibration frame 72, the support angle connected to the calibration frame 72 and the tension spring 73 will first contact with the assembled plate. The edges and corners come into contact, and under the resistance of the assembly board, the calibration frame 72 will be deflected and the other leg of the calibration frame 72 will move closer to the assembly board. At this time, the angle formed by the two legs can clamp the angle part of the assembly board, and the position of the assembly board is adjusted so that the assembly board is gradually placed neatly, so that the grinding device 2 can effectively contact the surface of the assembly board when grinding the assembly board. Through this setting, the operator does not need to place the assembly board neatly when placing it on the processing platform 11, and the four sets of calibration parts 7 can effectively fix the four corners of the assembly board, thereby avoiding the twisting of the assembly board during the grinding process to affect the grinding work of the grinding plate.

[0039] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 As shown:

[0040] S1: The operator places the assembled door panel to be polished on the processing platform 11, and then drives the electric cylinder 61 to drive one of the movable plates 64 to move. The movement of one of the movable plates 64 drives the rotating frame 62 to rotate through the setting of the connecting frame 63. The rotating frame 62 rotates and then drives another connecting frame 63 to move another movable plate 64. At this time, the two movable plates 64 move relative to each other and then drive the two assembled door panels placed on the processing platform 11 to move relative to each other. During the movement, the four sets of calibration parts 7 will respectively conflict with the side corners of the two assembled door panels. When the movable plate 64 contacts the calibration frame 72, the support angle connected to the calibration frame 72 and the tension spring 73 will first contact the assembled plate. The calibrating frame 72 is in contact with the corners of the assembling plate, and under the resistance of the assembling plate, the calibration frame 72 will be deflected so that the other leg of the calibration frame 72 is brought closer to the assembling plate. At this time, the angle formed by the two legs can clamp the angle part of the assembling plate, adjust the position of the assembling plate so that the assembling plate is gradually placed neatly, and then the grinding device 2 can effectively contact the surface of the assembling plate when grinding the assembling plate. And through this arrangement, the operator does not need to place the assembling plate neatly when placing it on the processing platform 11, and the four sets of calibration parts 7 can effectively fix the four corners of the assembling plate, thereby avoiding the twisting of the assembling plate during the grinding process, which affects the grinding work of the grinding plate;

[0041] S2: After the assembled board is limited by the mobile calibration device 6 on the processing platform 11, the operator adjusts the position of the movable frame 22 to move the movable frame 22 on the carrier frame 21, and makes the grinding block 5 at the bottom of the bearing sleeve 23 contact the top surface of the assembled board. Then, the driving motor 24 drives the bearing sleeve 23 to rotate. The bearing sleeve 23 rotates to grind the surface of the assembled board through the provided grinding block 5. The screw slide 13 can drive the bearing frame 21 to move so that the bearing sleeve 23 can grind the surface of the assembled board as a whole, thereby completing the grinding work of the assembled board.

[0042] S3: When the screw slide 13 drives the bearing sleeve 23 to move and grind the assembly plate, when the movement encounters the protrusion on the assembly plate, the protrusion on the assembly plate will resist the grinding block 5, and the resistance rod 31 corresponding to the protrusion will be driven to lift by the resistance, and after the resistance rod 31 corresponding to the protrusion is lifted by the pressure of the protrusion, the resistance rod 31 moves on the lower partition 231 and the middle partition 232, which will pull the triangular connecting block 42 to move on the fixed sleeve 41, and the movement of the triangular connecting block 42 will drive the pull rod 43 to move, and the slide groove 421 set on the triangular connecting block 42 will prevent the triangular connecting block 42 from moving when it first moves, and the movement of the pull rod 43 will pull the upper partition 233 The supporting sleeve 23 moves in the inner wall, and then lifts up the interference rod 31 of the part through the upper partition 233, and the interference rods 31 of the other parts are lifted up, so that the grinding block 5 is no longer in contact with the surface of the assembly disk. At this time, only the part of the raised part of the assembly plate is in contact with the corresponding interference rod 31. By setting the pressure spring 32 on the interference rod 31, the grinding block 5 is only used to grind the raised part of the assembly plate, and the other positions are no longer in contact with the assembly plate. Through this setting, when the assembly plate is ground, the raised part of the assembly plate can be effectively ground without contacting the rest of the raised part, thereby avoiding damage to the parts other than the raised part during the grinding process of the assembly plate.

5. A method for using a grinding device for producing assembled doors according to claim 4, comprising the following steps: The operator places the assembled door panel to be polished on the processing platform (11), and then drives the electric cylinder (61) to drive one of the movable plates (64) to move. The movement of one of the movable plates (64) drives the rotating frame (62) to rotate through the setting of the connecting frame (63). The rotating frame (62) rotates and drives the other connecting frame (63) to move the other movable plate (64). At this time, the two movable plates (64) move relative to each other and drive the two assembled door panels placed on the processing platform (11) to move relative to each other. During the movement, the four sets of calibration pieces (7) will respectively conflict with the two side corners of the two assembled door panels. When the movable plate (64) contacts the calibration frame (72), the calibration frame (72) is connected to the tension spring (73). The support angle will first contact the edge of the assembly board, and under the resistance of the assembly board, the calibration frame (72) will deflect and make the other support leg of the calibration frame (72) move closer to the assembly board. At this time, the angle formed by the two legs can clamp the angle of the assembly board, adjust the position of the assembly board so that the assembly board is gradually placed in an orderly manner, and then the grinding device (2) can effectively contact the surface of the assembly board when grinding the assembly board. Moreover, through this setting, the operator does not need to place the assembly board in an orderly manner when placing it on the processing platform (11), and the four sets of calibration parts (7) can effectively fix the four corners of the assembly board, thereby avoiding the phenomenon of the assembly board twisting during the grinding process to affect the grinding work of the grinding plate; S2: After the assembly plate is limited by the movable calibration device (6) on the processing platform (11), the operator adjusts the position of the movable frame (22) so that the movable frame (22) moves on the carrier frame (21), and the grinding block (5) at the bottom of the bearing sleeve (23) contacts the top surface of the assembly plate. Then, the driving motor (24) drives the bearing sleeve (23) to rotate. The bearing sleeve (23) rotates to grind the surface of the assembly plate through the provided grinding block (5). The screw slide (13) drives the bearing frame (21) to move so that the bearing sleeve (23) can grind the surface of the assembly plate as a whole, thereby completing the grinding work of the assembly plate. S3: When the screw slide (13) drives the bearing sleeve (23) to move and grind the assembly plate, when the movement encounters the protrusion on the assembly plate, the protrusion on the assembly plate will resist the grinding block (5), and the resisting rod (31) corresponding to the protrusion will be driven to lift by the resistance, and after the resisting rod (31) corresponding to the protrusion is resisted and lifted by the pressure of the protrusion, the resisting rod (31) moves on the lower partition (231) and the middle partition (232), and will pull the triangular connecting block (42) to move on the fixed sleeve (41), and the movement of the triangular connecting block (42) will drive the pull rod (43) to move, and the sliding groove (421) provided on the triangular connecting block (42) will prevent the triangular connecting block (42) from moving when it first moves, and the movement of the pull rod (43) will pull The upper partition (233) moves in the inner wall of the bearing sleeve (23), and then the upper partition (233) lifts up the resistance rod (31) of the part, and the resistance rods (31) of the other parts are lifted up, so that the grinding block (5) is no longer in contact with the surface of the assembly plate. At this time, only the part of the convex part of the assembly plate is in contact with the corresponding resistance rod (31). By setting the pressure spring (32) on the resistance rod (31), the grinding block (5) is only ground at the convex part of the assembly plate, and the other parts are no longer in contact with the assembly plate. Through this setting, when the assembly plate is ground, the convex part of the assembly plate can be effectively ground without contacting the other parts of the convex part, thereby avoiding damage to the parts other than the convex part during the grinding process of the assembly plate.
