Description

Technical Field

[0001] The invention relates to a wood workpiece grooving device. Background Art

[0002] The processing of wooden utensils is made by splicing wooden boards. When splicing wooden boards, it is necessary to open slots on the surface of the wooden boards, fill the slots with structural adhesive, and then insert the wooden boards to be spliced ​​into the slots and complete the gluing and fixing with structural adhesive.

[0003] For grooving of wooden boards, the mainstream processing methods are milling and planing. During milling, the wooden board needs to be clamped by a fixture, which is troublesome. In addition, the high speed of the milling cutter is prone to heat up. The heated milling cutter will cause burning and carbonization at the grooving position of the wooden board. Therefore, in the actual processing process, planing is more suitable. Grooving is to use a planer to move along the wooden board and use the tool to gradually groove.

[0004] In the prior art, grooving is carried out on a horizontal table surface. In the actual processing process, it is necessary to install an edge structure on the table surface, and then the wooden board is placed against the edge structure for grooving. During the retraction of the planer, the wooden board is easily displaced, resulting in inaccurate position of the secondary feed.

[0035] In addition, in the description of the present invention, “plurality” means at least two, for example, two, three, etc., unless otherwise clearly and specifically defined.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] See also Figure 1 The wooden workpiece grooving equipment shown in the figure includes a workbench 1, a bracket body 2 is installed at the bottom of the workbench 1, an equipment platform 3 is installed through the bracket body 2, the equipment platform 3 is parallel to the workbench 1, and a lifting device 4 is movably installed through the equipment platform 3, the lifting device 4 cooperates with the workbench 1, and the wooden board placed on the workbench 1 is lifted by the lifting device 4; a driving device 5 is arranged on the side of the workbench 1, a planer 6 is installed through the driving device 5, and the planer 6 slides parallel to the workbench 1, and a pressing plate device 7 is installed through the workbench 1, the bottom of the processed wooden board is supported by the lifting device 4, and the top is pressed by the pressing plate device 7, and two pressing plate devices 7 are arranged, which are respectively located on both sides of the travel path of the planer 6.

[0038] In the above technical solution, the plank to be grooved is placed on the workbench 1 and slides along the workbench 1 under the action of the pressing plate device 7. When the plank slides to the grooved position corresponding to the planer 6, the conveyance of the pressing plate device 7 is stopped, and the lifting device 4 acts on the bottom of the plank so that the height of the planer 6 is slightly lower than the upper surface of the plank. The planer 6 is driven by the driving device 5 to move and the planer 6 is used to groove the surface of the plank.

[0039] After the planer 6 runs one back and forth movement, it returns to its original position, at which point the lifting device 4 continues to lift the board, and the planer runs one back and forth movement again until the desired depth is reached (in this process, the space that the pressing plate device 7 can elastically compress is greater than the depth of the planing groove).

[0040] After reaching the groove depth, the lifting device 4 is lowered to the initial position, and the pressing plate device 7 drives the wooden board to move to the next groove position, and the above steps are repeated until the groove on the wooden board is completed.

[0041] In the above technical solution, there is no need to move the height of the planer 6, and only the height of the wooden board needs to be changed, thereby eliminating the need for a complicated planer height adjustment mechanism.

[0042] The initial position of the lifting device 4 can be slightly higher than the height of the workbench 1, so that the wooden board can slide along the lifting device 4 with smaller sliding resistance.

[0043] See also Figure 1 and Figure 2 As shown, the workbench 1 is tilted, and the tilt angle is 10 to 30 degrees. A baffle 101 is provided at the low position of the workbench 1, and the baffle 101 is perpendicular to the upper surface of the workbench 1. An open groove 102 is provided at the middle position of the baffle 101, and the open groove 102 corresponds to the planer 6. A mounting groove 103 runs through the board surface of the baffle 101, and a roller 104 is rotatably arranged in the mounting groove 103. The processed wooden board passes against the edge of the roller 104 and slides along the roller 104; a wheel groove 105 is provided on the table surface of the workbench 1, and the wheel groove 105 runs through vertically, and the lifting device 4 cooperates with the wheel groove 105.

[0044] In this embodiment, the inclination angle of the workbench 1 is 30°. By tilting the workbench 1, after the wooden board is placed on the workbench, it automatically slides down to the baffle 101 under the action of gravity. At this time, the wooden board is moved to the edge. The roller 104 installed on the baffle 101 reduces the resistance of the wooden board when it slides along the workbench 1.

[0045] The force on the wooden board during the planing process is perpendicular to the conveying direction of the wooden board, so the setting of the roller 104 does not affect the processing stability of the wooden board.

[0046] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the lifting device 4 includes a lifting frame 401, in which a plurality of supporting shafts 402 are arranged in parallel, and a roller 403 corresponding to the wheel groove 105 is rotatably installed on each of the supporting shafts 402. As the lifting frame 401 moves upward, a portion of the roller 403 passes through the wheel groove 105 and extends to the upper part of the workbench 1. A plurality of guide holes are provided at the four corners of the top of the equipment platform 3. A guide rod 404 matching the guide hole is installed at the bottom of the lifting frame 401, and a servo electric push rod 405 is installed through the equipment platform 3. The movable end of the servo electric push rod 405 is fixed to the lifting frame 401.

[0047] In the above technical solution, the diameter of the roller 403 is larger than the thickness of the overlapping lifting frame 401 and the workbench 1, so that when the lifting frame 401 moves upward under the drive of the servo electric push rod 405, the roller 403 has enough amount to extend to the outside of the wheel groove 105 to complete the lifting of the wooden board.

[0048] When the lifting frame 401 moves upward to the limit position, the height of the roller 403 needs to be slightly lower than the height of the planer 6, so as to avoid the planer 6 from colliding with another planer when the equipment fails.

[0049] See also Figure 4 As shown, on the equipment platform 3 , a linear bearing 31 is installed at the position corresponding to the guide hole, and the guide rod 404 cooperates with the linear bearing 31 .

[0050] The function of the linear bearing 31 is to make the sliding of the guide rod 404 smoother and more stable.

[0051] See also Figure 1 and Figure 5 As shown, the driving device 5 includes a side bracket 51 and an electric push rod 52. The side bracket 51 is welded and fixed to the side surface of the workbench 1. The electric push rod 52 is installed through the side bracket 51. The electric telescopic rod 52 is parallel to the upper surface of the workbench 1. The planer 6 is installed on the movable end of the electric push rod 52. A vertical plate 53 is installed on the top of the side bracket 51. The electric push rod 52 passes through the vertical plate 53. A first linear bearing 54 is installed through the vertical plate 53. A guide shaft 55 is slidably fitted through the first linear bearing 54, and one end of the guide shaft 55 fits the planer 6.

[0052] The planer 6 is driven by the electric push rod 52 to move, and the planer 6 is used to plan grooves on the surface of the wooden board.

[0053] The cooperation between the first linear bearing 54 and the guide shaft 55 can make the operation stability of the planer 6 higher and avoid angular deflection.

[0054] See also Figure 5 and Figure 6 As shown, the planer 6 includes a tool body 61, and a connecting member 62 fixed to the tool body 61, and the guide shaft 55 is connected through the connecting member 62. The tool body 61 has a tool head 63, and the tip of the tool head 63 is a blade 631; the connecting member 62 is L-shaped, and the connecting member 62 is connected to the tool body 61 by bolts. The movable end of the electric telescopic rod 52 is inserted into the connecting member 62 and fixed by bolts, and the guide shaft 55 is fixed to the connecting member 62.

[0055] See also Figure 6 As shown, a curved chip anti-chip plate 64 is disposed on the top of the tool body 61 .

[0056] The chip removal plate 64 is provided to discharge the curled wood chips generated during the planing process.

[0057] See also Figure 2 and Figure 7 As shown, the pressure plate device 7 includes a "7"-shaped upper bracket 701, a wheel frame 702 is arranged below the upper bracket 701, a wheel axle 703 is rotatably arranged in the wheel frame 702, and a plurality of pressure wheels 704 are fixedly installed on the wheel axle 703. A servo reduction motor 705 is installed at one end of the wheel frame 702, and the output end of the servo reduction motor 702 is connected to the wheel axle 703. A first guide rod 706 is arranged on the top of the wheel frame 702, and the first guide rod 706 passes through the upper bracket 701 upward. A first servo electric push rod 707 is installed on the top of the upper bracket 701, and a buffer device 8 is arranged on the top of the wheel frame 702, and the movable end of the first servo electric push rod 707 cooperates with the buffer device 8.

[0058] In the above technical solution, the wheel shaft 703 is driven to rotate by the servo reduction motor 702, and the lateral displacement of the wooden board is completed by the pressure of the pressure wheel 704. During the grooving process, the pressing force of the pressure wheel 704 is used to compact the wooden board to avoid the edge warping of the wooden board during the grooving process.

[0059] The setting of the buffer device 8 provides a flexible space for the pressure wheel 704 to move. When the lifting device 4 lifts the wooden board upward, the first servo electric push rod 707 can be kept stationary. By utilizing the compression of the buffer device 8, an elastic upward space is provided for the pressure wheel 704 to adapt to the position change of the wooden board.

[0060] See also Figure 8 As shown, the buffer device 8 includes a base 81, on the top of which a top cover 82 is detachably fitted, the bottom of the base 81 is fixedly connected to the wheel frame 702, a pressure plate 83 is movably provided in the base 81, a spring 84 is provided at the lower part of the pressure plate 83, and the movable end of the first servo electric push rod 707 passes through the top cover 82 and is fixedly connected to the pressure plate 83.

[0061] In the above technical solution, the compression of the spring 84 provides a buffering effect to the first servo electric push rod 707, thereby avoiding the rigid downward pressure of the pressure wheel without the effect of buffering, and avoiding the deformation of the wooden board caused by the rigid downward pressure.

[0062] The arrangement of the spring 84 also provides elastic space for the upward movement of the wooden board.

[0063] See also Figure 7 As shown, a wheel groove is provided on the outside of the pressure wheel 704, and a rubber tire 744 is fitted in the wheel groove. The tire 744 protrudes to the outside of the wheel groove, and the surface of the tire 744 is rough. The surface of the tire 744 is processed with an annular anti-skid groove 745.

[0064] The tire 744 can be elastically deformed. After the tire 744 is elastically deformed, the contact area between the tire 744 and the wooden board increases, and the fixing effect of the wooden board is better.

[0065] Secondly, the elastic deformation of the tire 744 also provides a certain degree of protection for the surface of the wooden board.

[0066] The provision of the anti-slip groove 745 can increase the stability when in contact with the wooden board.
