Description

Technical Field

[0001] This invention relates to table processing equipment, and more specifically, to a table tapered column processing device and process. Background Technology

[0002] Currently, some tables have tapered uprights made by covering the outside of the upright frame with a cladding panel, and the upright cladding panel is made using methods such as... Figure 1 The process shown involves a 3mm thick sheet 200 (this thickness is the standard sheet thickness; if the thickness is too thick, it will not easily deform). However, because the sheet 200 is relatively thin, a single layer of sheet 200 is difficult to form. Therefore, a double layer of sheet 200 is often used. During production, a first layer of sheet 200 is placed on the surface of the lower mold 100, and glue is applied to the upper part of the first layer of sheet 200. Then, the second layer of sheet 200 is attached to the first layer of sheet 200. The sheet 200 is then hot-pressed and formed by pressing down through the upper mold 300. After forming, it is cut to size to form half of a conical sheet 400. Finally, the two conical sheets 400 are spliced ​​on the outside of the column frame and fixed to the column frame with carpenter's nails. This method is very time-consuming, not conducive to mass production, and cannot be made into a cladding using a single layer of sheet 200, resulting in high costs. Therefore, there is an urgent need to improve this method. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a table conical column processing device and process. By setting up the processing device, it is not only convenient to manufacture the column frame, but also convenient to directly cover the outside of the column frame with a thin plate to realize the manufacturing of the column.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a table conical column processing device, including a workbench, a work frame and a support platform on the upper part of the workbench, a lifting mechanism on the upper part of the work frame, a pressure block connected to the lower part of the lifting mechanism, the lifting mechanism being able to drive the pressure block to move up and down, the pressure block being located directly above the support platform, movable arms hinged to both sides of the work frame, the movable arms including positioning plates, a processing area being formed between the support platform and the pressure block, and rotating the movable arms to move the positioning plates closer to or further away from the processing area.

[0005] Furthermore, the movable arm includes a movable frame, one side of which is hinged to the work frame, and the other side of the movable frame is equipped with a push rod and a second adjusting rod at its upper and lower ends, respectively. The push rod is hinged to the upper end of the positioning plate and the second adjusting rod is hinged to the lower end of the positioning plate. When the positioning plate is located directly in front of the processing area, the distance and angle between the positioning plate and the processing area can be adjusted by the push rod and the second adjusting rod.

[0006] Furthermore, the positioning plates are a left plate located on the left movable arm and a right plate located on the right movable arm. The left plate has a first binding area and a second binding area arranged side by side along its length, and the right plate has a third binding area arranged side by side along its length.

[0007] Furthermore, the work frame is provided with a hinge seat on the side, and a limiting groove is provided in the hinge seat. One side of the movable frame is inserted into the limiting groove and hinged. The movable frame can abut against the side of the limiting groove. When the movable frame abuts against the side of the limiting groove facing the work frame, the positioning plate is located directly in front of the processing area.

[0008] Furthermore, the lifting mechanism includes a lifter fixed to the upper part of the work frame, a second connecting platform connected to the telescopic rod of the lifter, the lower end of the second connecting platform being connected to the pressure block, and a positioning piece provided on the front of the second connecting platform.

[0009] Furthermore, the lifting mechanism is rotatably connected to the pressure block, and the upper part of the support platform is provided with a first connecting platform and a limiting mechanism. The first connecting platform is rotatably connected to the support platform, and the limiting mechanism can abut against or disengage from the support platform.

[0010] Furthermore, the upper part of the worktable is provided with a protruding plate, the side of the support table is provided with annular ribs, and the limiting mechanism includes an arc-shaped claw, which can abut against the side of the annular ribs or disengage from the annular ribs.

[0011] Furthermore, the push rod is an electric push rod, the second adjusting rod is a lead screw, and the second adjusting rod has two nuts externally threadedly connected, with the two nuts respectively abutting against both sides of the movable frame.

[0012] A process for manufacturing a tapered table column includes the following steps:

[0013] S1. Fabrication of column components: process the base plate, top plate, and multiple wooden strips, and draw the positioning reference lines for the wooden strips on the surface of the base plate and top plate;

[0014] S2. Column Frame Construction:

[0015] ① Adjust the pressure block to a suitable height using the lifting mechanism. The distance between the pressure block and the support platform should be greater than the height of the main column.

[0016] ② Place the base plate on the upper part of the support platform;

[0017] ③ Place an auxiliary rod on the upper part of the base plate;

[0018] ④ Place a top plate on the upper part of the auxiliary rod;

[0019] ⑤ The lifting mechanism drives the pressure block to descend until the lower part of the pressure block abuts the upper part of the top plate;

[0020] ⑥ Insert a wooden strip between the bottom plate and the top plate from the front of the processing area. The middle of the upper end of the wooden strip should be aligned with the baseline of the top plate and the outer edge should correspond to the outer contour of the top plate. The middle of the lower end of the wooden strip should be aligned with the baseline of the bottom plate and the outer edge should correspond to the outer contour of the bottom plate.

[0021] ⑦. Drive nails downwards at an angle on the side of the wooden strip near the bottom to fix the bottom of the wooden strip to the base plate, and drive nails upwards at an angle on the side of the wooden strip near the top to fix the top of the wooden strip to the top plate.

[0022] ⑧ Rotate the support platform and pressure block, and fix the remaining wooden strips using the methods in steps ⑥ and ⑦. When more than two-thirds of the wooden strips are fixed, remove the auxiliary rod and then fix the remaining wooden strips.

[0023] 9. Complete the construction of the column frame;

[0024] S3, Wrapping plate: Wrapping the fan-shaped thin plate around the outside of the column frame;

[0025] S4. Complete the construction of the pillars.

[0026] Further, the board wrapping process includes:

[0027] S1. Adjust the initial position of the positioning plate;

[0028] S2. Place one side of the fan-shaped thin plate against the surface of one of the wooden strips, ensuring that the wooden strip has a sufficient exposed area;

[0029] S3. Rotate and close the movable arm that holds the left plate, so that the inner side of the left plate abuts against the surface of the fan-shaped thin plate;

[0030] S4. Nail along the first binding area of ​​the left board to secure the starting edge of the fan-shaped sheet and the wooden strip there;

[0031] S5. Open the movable arm with the left plate fixed in place;

[0032] S6. Rotate the column frame so that the next wooden strip is directly in front of the processing area;

[0033] S7. Rotate and close the movable arm that holds the right plate so that the inner side of the right plate abuts against the surface of the fan-shaped thin plate.

[0034] S8. Nail along the third binding area of ​​the right panel to secure the fan-shaped thin board and the wooden strip there;

[0035] S9. Repeat steps S6-S8 to fix the fan-shaped thin plate and the remaining wooden strips so that the fan-shaped thin plate covers the outside of the column frame.

[0036] S10. The end edge of the fan-shaped thin plate overlaps with the starting edge. The end edge is cut off so that it is flush with the starting edge and abuts against the area where the wooden strip was exposed in step S2.

[0037] S11. Open the movable arm with the right plate fixed, and close the movable arm with the left plate fixed, so that the left plate abuts against the end surface of the fan-shaped thin plate.

[0038] S12. Nail along the second binding area of ​​the left board to secure the end edge of the fan-shaped thin board to the wooden strip there.

[0039] In summary, the present invention has the following beneficial effects:

[0040] 1. By rotating the telescopic section, the length of the auxiliary rod can be adjusted, and in conjunction with the lifting frame, it can not only meet the processing needs of column frames of different heights, but also facilitate the removal of the auxiliary rod;

[0041] 2. The positioning plate can hold down the fan-shaped thin plate. The binding area inside the positioning plate is the nailing area. When binding the column frame and the fan-shaped thin plate, the side of the fan-shaped thin plate is placed against the outside of the wooden strip inside the column frame located on the front of the processing area. The movable arm is moved so that the positioning plate is located on the front of the processing area and holds down the fan-shaped thin plate. At this time, the operator holds the fan-shaped thin plate with one hand and uses the nailing machine in the other hand to nail along the binding area, thereby fixing the binding of the fan-shaped thin plate and the column frame. When binding the fan-shaped thin plate, the fan-shaped thin plate can be passed through the auxiliary rod on the upper part of the workbench. The auxiliary rod provides auxiliary support for the fan-shaped thin plate. If the size of the fan-shaped thin plate is large, it can also be fixed with the help of other workers. After the fan-shaped thin plate covers the column frame, the areas of the fan-shaped thin plate exposed on the bottom plate and top plate are trimmed to finally make the column body. Using the above method, not only can the production efficiency of the column body be greatly improved, but also only a single layer of fan-shaped thin plate is needed to cover the column frame, reducing material costs.

[0056] 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.

[0057] like Figures 2 to 13As shown, this embodiment discloses a table conical column processing device for processing column body 7, including a workbench 1. The workbench 1 is provided with a work frame 11 and a support platform 2 on its upper part. The support platform 2 is provided with a first connecting platform 12. A flat ball bearing (not shown in the figure) is installed inside the first connecting platform 12. The first connecting platform 12 and the support platform 2 are rotatably connected through the bearing. A first positioning head 21 is provided at the center of the upper part of the support platform 2. A through hole is provided at the center of the bottom plate 71 of the column body 7. During processing, the bottom plate 71 is placed on the upper part of the support platform 2, and the first positioning head 21 is inserted into the through hole to realize the placement and positioning of the bottom plate 71.

[0058] like Figure 6 As shown, a limiting mechanism 5 is provided on the side of the support platform 2. The limiting mechanism 5 can restrict the rotation of the support platform 2. Specifically, the limiting mechanism 5 can abut against or disengage from the support platform 2. The upper part of the workbench 1 is provided with a protruding plate 14, and the side of the support platform 2 is provided with annular ribs 22. The limiting mechanism 5 includes an arc-shaped claw 51. The arc-shaped claw 51 can abut against or disengage from the side of the annular rib 22. A first adjusting rod 52 and a guide rod 54 are respectively provided on one side of the arc-shaped claw 51. The first adjusting rod 52 and the guide rod 54 respectively pass through the protruding plate 14. The first adjusting rod 52 is rotatably connected to the arc-shaped claw 51 and threadedly connected to the protruding plate 14. Rod 52 is a lead screw. One end of the first adjusting rod 52 is fixed with a handle 53 and the other end is fixed with a fourth connecting platform 521. A third connecting platform 511 is provided on the outside of the arc-shaped claw 51. A flat ball bearing (not shown in the figure) is installed in the third connecting platform 511. The third connecting platform 511 and the fourth connecting platform 521 are connected through the bearing. With the above design, when it is necessary to restrict the rotation of the support platform 2, simply hold the handle 53 and rotate the first adjusting rod 52 to push the arc-shaped claw 51 close to the annular rib 22. When the arc-shaped claw 51 abuts and squeezes the annular rib 22, it can fix the support platform 2 and prevent the rotation of the support platform 2, thereby facilitating the processing of the column.

[0059] By setting the arc-shaped claw 5, the contact area with the annular rib 22 can be effectively increased. Furthermore, the outer surface of the annular rib 22 and the inner surface of the arc-shaped claw 51 are both uneven planes. When the inner surface of the arc-shaped claw 51 abuts against the outer surface of the annular rib 22, a large frictional force will be generated, which can effectively fix the support platform 2 and prevent the support platform 2 from rotating during the processing of the column.

[0060] like Figure 4 and Figure 5As shown, the upper part of the work frame 11 is provided with a lifting mechanism 3, and the lower part of the lifting mechanism 3 is connected to a pressure block 4. The lifting mechanism 3 can drive the pressure block 4 to move up and down. Specifically, the lifting mechanism 3 includes a lifter 31 fixed to the upper part of the work frame 11. The lifter 31 is an electric screw lifter, which is the prior art. The telescopic rod of the lifter 31 is connected to a second connecting platform 32. The second connecting platform 32 and the telescopic rod of the lifter 31 are connected through a buffer 34. A spring is provided in the buffer 34. By compressing the spring, a buffering function can be achieved to avoid excessive pressure on the pressure block 4. The buffer 34 is the prior art. Its specific structure, as well as the cooperation structure between the buffer 34 and the lifter 31 and the second connecting platform 32, will not be described in detail in this specification.

[0061] like Figure 2 and Figure 5 As shown, the lower end of the second connecting platform 32 is connected to the pressure block 4, specifically through a planar ball bearing (not shown in the figure). The pressure block 4 is located directly above the support platform 2, and a processing area is formed between the support platform 2 and the pressure block 4. The lower part of the pressure block 4 is provided with a second positioning head 41, which is directly opposite to the first positioning head 21. The top plate 73 is provided with a through hole that is consistent with the bottom plate 72. During processing, the upper part of the top plate 73 abuts against the lower part of the pressure block 4 and the second positioning head 41 is inserted into the through hole of the top plate 73 for positioning.

[0062] like Figures 4 to 6 As shown, the second connecting platform 32 has a positioning piece 33 on its front side and a positioning point on the upper part of the arc-shaped claw 51. The positioning piece 33 and the positioning point are both located directly in front of the processing area. When making the base plate 72 and the top plate 73, positioning reference lines for wooden strips 74 are drawn on the surfaces of the base plate 72 and the top plate 73. In this embodiment, twelve wooden strips 74 are used. Therefore, twelve reference lines evenly distributed along their corresponding axes need to be drawn on the surfaces of the base plate 72 and the top plate 73. During processing, the initial position of the top plate 73 is located by the positioning piece 33 and the reference line on the surface of the top plate 73, and the initial position of the base plate 72 is located by the positioning point and the reference line on the surface of the base plate 72. Since the positioning point is far from the reference line on the surface of the base plate 72, when the wooden strip 74 is inserted between the top plate 73 and the base plate 72, after the upper end of the wooden strip 74 is positioned, a level can be used to position the lower end of the wooden strip 74 and the base plate 72 to ensure that the wooden strip 74 is in a vertical state.

[0063] like Figure 3As shown, since the top plate 73 and the bottom plate 72 are not initially connected, they need to be connected by an auxiliary rod 8 before the wooden strips 74 are attached. The auxiliary rod 8 includes a support section 81 and a telescopic section 82. The lower end of the telescopic section 82 is inserted into the support section 81. The telescopic section 82 and the support section 81 are connected by threads. By rotating the telescopic section 82, the length of the auxiliary rod 8 can be adjusted. In conjunction with the lifting frame 3, it can not only meet the processing operations of the column frames 71 at different heights, but also facilitate the removal of the auxiliary rod 8.

[0064] like Figure 2 and Figure 11 As shown, the work frame 11 has movable arms 6 hinged to both sides. Specifically, each movable arm 6 includes a movable frame 61, which is an arc-shaped support. One side of the movable frame 61 is hinged to the work frame 11. The work frame 11 has a hinge seat 13 on its side. The movable frame 61 and the hinge seat 13 are connected by a damping pivot. The damping pivot is existing technology. By setting the damping pivot, the rotational resistance of the movable arm 6 can be increased, preventing the movable arm 6 from rotating when it is not under force or under very small thrust. The hinge seat 13 has a limiting groove 131. One side of the movable frame 61 is inserted into the limiting groove 131 and hinged. The movable frame 61 can abut against the side of the limiting groove 131. The movable arm 6 includes a positioning plate 63. Rotating the movable arm 6 allows the positioning plate 63 to move closer to or away from the processing area. When the movable frame 61 abuts against the side of the limiting groove 131 facing the work frame 11, the positioning plate 63 is located directly in front of the processing area. Figure 2 This is a diagram showing the state after the two movable arms 6 are extended. At this time, the positioning plate 63 is far away from the processing area. In this state, sufficient space can be provided for the processing of the column frame 71. Figure 7 The left movable arm 6 is in the retracted state, in which it can process the fan-shaped thin plate 9 and the column frame 71.

[0065] like Figures 7 to 10As shown, the positioning plate 63 can hold down the fan-shaped thin plate 9. The binding area within the positioning plate 63 is the nailing area. When binding the column frame 71 and the fan-shaped thin plate 9, the side of the fan-shaped thin plate 9 is placed against the outside of the wooden strip 74 located on the front of the processing area inside the column frame 71. The movable arm 6 is moved so that the positioning plate 63 is located on the front of the processing area and holds down the fan-shaped thin plate 9. At this time, the operator holds the fan-shaped thin plate 9 with one hand and uses a nailer in the other hand to nail along the binding area, thereby fixing the binding of the fan-shaped thin plate 9 and the column frame 71. When binding the fan-shaped thin plate 9, the fan-shaped thin plate 9 can be removed from the work area. The auxiliary frame 15 on the upper part of the workbench 1 passes through and provides auxiliary support for the fan-shaped thin plate 9. If the fan-shaped thin plate 9 is large, it can be fixed with the help of other workers. After the fan-shaped thin plate 9 covers the column frame 71, the area of ​​the fan-shaped thin plate 9 exposed on the bottom plate 72 and the top plate 73 is trimmed to finally make the column body 7. By adopting the above method, not only can the production efficiency of the column body 7 be greatly improved, but also only a single layer of fan-shaped thin plate 9 is needed to cover the column frame 71, which reduces material costs.

[0066] Among them, such as Figure 10 As shown, the binding area includes a first binding area 64, a second binding area 65, and a third binding area 66. The positioning plates 63 are a left plate 631 located on the left movable arm 6 and a right plate 632 located on the right movable arm 6. The first binding area 64 and the second binding area 65 are arranged side by side along the length of the surface of the left plate 631, and the third binding area 66 is arranged side by side along the length of the surface of the right plate 632. The first binding area 64 includes a plurality of first connecting ribs 642 spaced apart along its length, and a first guide groove 641 is formed between two adjacent first connecting ribs 642. The second binding area 65... Zone 65 includes a plurality of second connecting ribs 652 arranged along its length, and a second guide groove 651 is formed between two adjacent second connecting ribs 652. The first connecting rib 642 is staggered with the second connecting rib 652. The third binding zone 66 includes a plurality of third connecting ribs 662 arranged along its length, and a third guide groove 661 is formed between two adjacent third connecting ribs 662. The first guide groove 641, the second guide groove 651 and the third guide groove 661 can all be nailed. The first connecting rib 642, the second connecting rib 652 and the third connecting rib 662 all play a role in structural reinforcement.

[0067] like Figure 10 and Figure 13As shown, when the left board 631 and the right board 632 overlap, the third binding area 66 is located between the first binding area 64 and the second binding area 65. The first binding area 64 is used to bind the right side of the wooden strip 74, the second binding area 65 is used to bind the left side of the wooden strip 74, and the third binding area 66 is used to bind the middle area of ​​the wooden strip 74. The two edges of the fan-shaped thin plate 9 are assisted in binding by the first binding area 64 and the second binding area 65, and the area between the two edges is assisted in binding by the third binding area 66. By setting the first binding area 64, the second binding area 65 and the third binding area 66, a positioning function can be achieved. This not only ensures that the fan-shaped thin plate 9 can be fixed to each wooden strip 74, but also ensures higher binding accuracy and better consistency during mass production.

[0068] like Figure 9 As shown, a push rod 62 and a second adjusting rod 67 are respectively installed at the upper and lower ends of the other side of the movable frame 61. The push rod 62 is hinged to the upper end of the positioning plate 63, and the second adjusting rod 67 is hinged to the lower end of the positioning plate 63. When the positioning plate 63 is located directly in front of the processing area, the distance and angle between the positioning plate 63 and the processing area can be adjusted by the push rod 62 and the second adjusting rod 67. The push rod 62 is an electric push rod, and the second adjusting rod 67 is a lead screw. The second adjusting rod 67 has two nuts connected to its external threads. The two nuts abut against both sides of the movable frame 61. Since the dimensions of different tapered columns are different, the second adjusting rod 67 can be adjusted to accommodate different sizes of bottom plates 72, and the push rod 62 can be adjusted to accommodate different sizes of top plates 73. The cooperation between the second adjusting rod 67 and the push rod 62 can accommodate the production of column bodies 7 with different tapers.

[0069] This embodiment is used to process column bodies 7 with a height of 650mm-730mm. The length of the positioning plate 63 is 780mm, and the lengths of the first binding area 64, the second binding area 65 and the third binding area 66 are 750mm. The lower end of the binding area is always below the bottom plate 72, and the upper end is always above the top plate 73.

[0070] A table cone column processing technology using the above-mentioned processing device includes the following steps:

[0071] S1. Fabrication of column components: Process the base plate 72, top plate 73 and multiple wooden strips 74 respectively, and draw positioning reference lines for the wooden strips 74 on the surface of the base plate 72 and top plate 73. In this embodiment, there are 12 wooden strips 74, so it is necessary to draw 12 reference lines on the surface of the base plate 72 and top plate 73 respectively, and the angle between two adjacent reference lines is 30 degrees.

[0072] S2, Column Frame 71 Construction:

[0073] ① Adjust the pressure block 4 to a suitable height using the lifting mechanism 3. The distance between the pressure block 4 and the support platform 2 should be greater than the height of the column body 7.

[0074] ② Place the base plate 72 on the upper part of the support platform 2, insert the first positioning head 21 into the center hole of the base plate 72, and limit the support platform 2 by the limiting mechanism 5 before the base plate 72 is placed on the upper part of the support platform 2.

[0075] ③ Place an auxiliary rod 8 on the top of the base plate 72. The thickness of both the base plate 72 and the top plate 73 is 18mm. If the column body 7 with a height of 700mm is to be processed, the length of the auxiliary rod 8 should be adjusted to 664mm.

[0076] ④ Place the top plate 73 on the upper part of the auxiliary rod 8;

[0077] ⑤ The lifting mechanism 3 lowers the pressure block 4 until its lower part abuts against the upper part of the top plate 73. The second positioning head 41 at the lower part of the pressure block 4 is inserted into the center hole of the top plate 73. Before the pressure block 4 is fully pressed, one of the reference lines of the bottom plate 72 and the top plate 73 needs to be adjusted to the frontmost position. The reference line of the top plate 73 is positioned by the positioning piece 33, ultimately forming the following shape. Figure 3 The state shown;

[0078] ⑥ Insert a wooden strip 74 between the base plate 72 and the top plate 73 from the front of the processing area. The middle of the upper end of the wooden strip 74 should be aligned with the baseline of the top plate 73, and its outer edge should correspond to the outer contour of the top plate 73. The middle of the lower end of the wooden strip 74 should be aligned with the baseline of the base plate 72, and its outer edge should correspond to the outer contour of the base plate 72. After the upper end of the wooden strip 74 is positioned with the top plate 73, place a level against one side of the wooden strip 74 and fine-tune the wooden strip 74 using the level to ensure that it is vertical, forming a shape as shown. Figure 4 As shown, the vertical height of the wooden strip 74 should be 664mm.
