Description

Technical Field

[0001] The present invention relates to the technical field of building engineering, and more particularly to an adjustable automatic wood board circle cutting device for building. Background Art

[0002] In building decoration projects, in order to meet decoration needs, it is often necessary to cut out round wooden boards to play a decorative role.

[0003] Currently, when cutting a circle with a wooden board, the wooden board is usually placed on a workbench for positioning and fixing, and then a jig saw is used to make the jig saw revolve to cut the wooden board in a circle. However, when cutting a circle with a jig saw, it is usually necessary to leave the part of the wooden board to be cut in the air to provide space for the saw blade of the jig saw to move and cut.

[0004] However, in the process of producing and processing veneer panels, when the veneer panels are cut into circles by a curved saw, the cut portion of the veneer panels needs to be suspended in the air. Since the veneer panels are very thin and the curved saw cuts by the reciprocating motion of the saw blade, the bottom of the veneer panels is suspended in the air, and the veneer panels are very thin and have high flexibility, the veneer panels will vibrate violently during the reciprocating motion of the saw blade, which may easily cause uneven cutting of the edges of the veneer panels during the cutting process. Furthermore, since the veneer panels are very thin, the subsequent polishing process may easily cause over-polishing, resulting in unusable veneer panels. Summary of the invention

[0005] The present invention provides an adjustable automatic wood board circle cutting device for construction, and aims to solve the following problem: currently, when a veneer board is circled by a curved saw, the cut portion of the veneer board needs to be suspended in the air. Since the veneer board is very thin, and the cutting of the curved saw is performed by the reciprocating motion of the saw blade, at this time, since the bottom of the veneer board is suspended in the air, and the veneer board is very thin and has high flexibility, the veneer board will vibrate violently during the reciprocating motion of the saw blade, which will easily cause the edge of the veneer board to be cut unevenly during the circle cutting process.

[0035] Refer to the instruction manual Figures 1 to 7 , an adjustable automatic wood board circle cutting device for construction, comprising: a body 1, a workbench 2 is arranged on the body 1, and a groove 21 is opened on the workbench 2;

[0036] A pressure plate 4 capable of vertical linear motion is disposed on the machine body 1, a jigsaw 5 is disposed on one side of the pressure plate 4, and a rotary drive mechanism 6 is disposed on the pressure plate 4, the rotary drive mechanism 6 is used to drive the jigsaw 5 to perform orbital motion around the pressure plate 4;

[0037] The pressure plate 4 is also provided with a linear drive mechanism 2 7, which is used to drive the jigsaw 5 to adjust its position laterally;

[0038] A support mechanism 10 is arranged in the groove 21, and the support mechanism 10 includes a support 101, and a plurality of support plates 103 are slidably arranged on the support 101, and the support plates 103 are used to support the bottom of the wood board to be cut;

[0039] The support 101 is provided with an adjustment mechanism 12 , and the adjustment mechanism 12 is used to adjust the number of the support plates 103 .

[0040] It should be noted that the pressure plate 4 is used to press and fix the wooden board to be cut, and the adjustment mechanism 12 adjusts the number of support plates 103 used for support according to the required cutting circle radius, so that during the cutting process, the bottom position of the wooden board to be cut with the required cutting circle radius is supported and fixed.

[0041] The specific implementation scenario is as follows: the wooden board to be cut is placed on the workbench 2, and then the number of support plates 103 is adjusted through the adjustment mechanism 12 according to the required cutting circle radius, so that the support plates 103 of the corresponding radius number support the bottom of the wooden board to be cut, so as to avoid that the saw blade movement of the curved saw 5 is blocked by too many support plates 103, and according to the required cutting circle radius, the lateral position of the curved saw 5 is adjusted through the linear drive mechanism 2 7, and then the pressure plate 4 is moved downward to press and fix the wooden board to be cut, and then the rotary drive mechanism 1 6 drives the curved saw 5 to revolve around the pressure plate 4, and the curved saw 5 is used to cut the wooden board to be cut. During the cutting circle operation, the bottom of the wooden board to be cut can be supported according to the required cutting circle radius, so as to avoid the problem that the reciprocating motion of the saw blade during the cutting circle causes the wooden board to be cut to vibrate and affect the cutting circle quality.

The output end of the driving member 31 is fixedly connected to a threaded rod 32, and a slide seat 33 is threadedly matched on the threaded rod 32. The pressure plate 4 is fixedly installed at the bottom of the slide seat 33.

[0043] It should be noted that the driving member 31 is a motor, which drives the threaded rod 32 to rotate, drives the slide 33 to move vertically and linearly, and makes the slide 33 drive the pressure plate 4 to move vertically and linearly.

[0044] For further information, please refer to the attached manual. Figure 1 and Figure 3The rotary drive mechanism 6 includes a sleeve 61, which is rotatably mounted on the pressure plate 4.

[0045] It should be noted that the power component 62 is a motor, which drives the driving gear 63 to rotate, and through the meshing transmission of the driving gear 63 and the driven gear 64, it drives the sleeve 61 to rotate, so that the sleeve 61 can drive the curved saw 5 to perform orbital motion to cut the wood board to be cut in a circle.

[0046] For further information, please refer to the attached manual. Figure 4 A linear drive mechanism 7 is provided on the sleeve 61, and the linear drive mechanism 7 includes a horizontal plate 71, which is fixedly provided on the sleeve 61, and a driving member 72 is fixedly installed at the bottom of the horizontal plate 71, and a threaded rod 73 is fixedly connected to the output end of the driving member 72, and a slider 74 is threadedly matched on the threaded rod 73, and the jig saw 5 is fixedly provided at the bottom of the slider 74.

[0047] It should be noted that the driving member 72 is a motor, which drives the threaded rod 73 to rotate, so that the threaded rod 73 drives the slider 74 to move horizontally and linearly, thereby driving the curved saw 5 to move horizontally and linearly through the slider 74, so as to adjust the position of the curved saw 5, thereby adjusting the position of the curved saw 5 according to the required cutting circle radius.

[0048] For further information, please refer to the attached manual. Figure 5 A linear drive mechanism three 8 and a linear drive mechanism four 9 are provided on the machine body 1. The linear drive mechanism three 8 is used to drive the workbench 2 to move linearly forward and backward, and the linear drive mechanism four 9 is used to drive the workbench 2 to move linearly left and right. The linear drive mechanism three 8 includes a driving member three 81, and the output end of the driving member three 81 is fixedly connected with a threaded rod three 82, and the threaded rod three 82 is threadedly matched with a moving seat 83. The linear drive mechanism four 9 includes a driving member four 91, and the output end of the driving member four 91 is fixedly connected with a threaded rod four 92, and the threaded rod four 92 is threadedly matched with a support seat 93, and the workbench 2 is fixedly installed on the support seat 93.

[0049] It should be noted that the driving member three 81 and the driving member four 91 are both motors, and the linear driving mechanism three 8 and the linear driving mechanism four 9 are used to move and adjust the front, back, left and right positions of the workbench 2 so that the center positions of the workbench 2 and the pressure plate 4 are aligned in the vertical direction.

[0050] For further information, please refer to the attached manual. Figure 6The support mechanism 10 also includes a plurality of slide grooves 102 opened on the support 101, a plurality of support plates 103 are slidably arranged in the corresponding slide grooves 102, an elastic member 104 is arranged at the bottom of the plurality of support plates 103, and the support 101 is rotatably arranged in the workbench 2.

[0051] It should be noted that the elastic member 104 is a spring. Figure 6 As shown, the spring is in a stretched state at this time, and by providing a plurality of slidably arranged support plates 103, a corresponding number of support plates 103 can be adjusted according to the required cutting circle radius.

[0052] For further information, please refer to the attached manual. Figure 6 A rotation drive mechanism 11 is arranged in the groove 21, and the rotation drive mechanism 11 includes a power component 111. The output end of the power component 111 is fixedly connected with a gear 112. A gear ring 113 is fixedly installed at the bottom of the support 101, and the gear 112 is meshed with the gear ring 113.

[0053] It should be noted that the second power component 111 is a motor, which drives the gear 112 to rotate, so that the gear 112 is meshed with the gear ring 113, so that the gear ring 113 can drive the support 101 to rotate, thereby driving the support plate 103 to move synchronously, and making the movement speed of the curved saw 5 during the revolution consistent with the rotation speed of the support 101. Since the support plate 103 can only support part of the bottom of the wooden board to be cut, by making several support plates 103 fit and move synchronously with the curved saw 5 during the circle cutting process, it can be ensured that during the circle cutting process, the bottom of the cutting part of the wooden board to be cut is always supported and fixed, thereby ensuring stable support of the wooden board to be cut during the cutting process, so as to avoid vibration during the cutting process that affects the cutting quality.

[0054] For further information, please refer to the attached manual. Figure 7 and Figure 8 The adjustment mechanism 12 includes a plurality of side rods 121, and the plurality of side rods 121 are fixedly connected to the corresponding support plates 103, and the ends of the plurality of side rods 121 extend out of the support 101, and a driving member 5 122 is fixedly installed at the bottom of the support 101, and a threaded rod 5 123 is fixedly connected to the output end of the driving member 5 122, and a sliding rod 124 is threadedly engaged on the threaded rod 5 123, and the top of the sliding rod 124 is in active contact with the plurality of side rods 121, and the sliding rod 124 is slidably arranged in the support 101, and the end of the sliding rod 124 is arranged with an inclined surface.

[0055] It should be noted that the driving member 122 is a motor, which drives the threaded rod 123 to rotate, so that the threaded rod 123 drives the sliding rod 124 to move horizontally, so that the sliding rod 124 can be separated from the corresponding number of side rods 121, so that under the action of the elastic member 104, the side rod 121 that is not in contact with the sliding rod 124 can drive the corresponding support plate 103 to move downward, so that according to the required cutting circle radius, an appropriate number of support plates 103 can be adjusted to support the wooden board to be cut.

[0056] In the above technical scheme, during the circle cutting process, the cutting is performed by the reciprocating motion of the saw blade of the curved saw 5. During the cutting process, the saw blade of the curved saw 5 will contact and rub against the wooden board to be cut, causing the saw blade of the curved saw 5 to heat up after being used for a period of time. When the saw blade of the curved saw 5 heats up to a certain temperature, during the cutting process, since the thickness of the wooden board to be cut is very thin, the high temperature can easily cause the edge of the cut circular wooden board to be affected by the high temperature, causing the edge of the cut circular wooden board to be deformed by the high temperature, affecting the quality of the finished product. For this reason, the present invention proposes a cooling mechanism 13, which is used to cool the saw blade of the curved saw 5 during the cutting process.

[0057] For details, please refer to the attached manual. Fig. 9 The jigsaw 5 is provided with a cooling mechanism 13 , which includes an air blowing component 131 , an air outlet of the air blowing component 131 is connected to a nozzle 132 , and an air outlet of the nozzle 132 points to the saw blade of the jigsaw 5 .

[0058] It should be noted that the air blowing component 131 is an air pump, which outputs air and blows the air toward the saw blade of the jigsaw 5 through the nozzle 132, so that the saw blade of the jigsaw 5 can be cooled during the cutting process to avoid the problem that the saw blade of the jigsaw 5 is easily heated up due to friction after long-term use, affecting the quality of the finished product.

[0059] In the above technical scheme, in order to ensure full utilization of the board material, after several round boards are cut out from the wood board to be cut, there are usually some scraps that can be used to cut out round boards. When the round boards are cut out from some scraps, when the scraps are fixed and cut into circles, since the scrap wood boards are usually smaller, except for the part that needs to be cut out into round boards, the rest of the scraps are usually left suspended on the groove 21. When cutting into circles at this time, since the rest of the scraps are suspended, when the cutting into circles is about to be completed, the rest of the scraps are still partially adhered to the required round board part. Under the action of gravity, this part is prone to drooping. However, since there is still a part of adhesion, when cutting this adhered part at this time, it is easy to cause cutting deviation in this part, resulting in problems affecting the quality of the finished product. For this reason, the present invention proposes an edge fixing mechanism 14, which is used to fix the edge position of the scraps during the process of cutting into circles for smaller scraps.

[0060] For details, please refer to the attached manual. Fig.10 and Fig.11 An edge fixing mechanism 14 is provided on the workbench 2, and the edge fixing mechanism 14 includes a cylinder 141. The output end of the cylinder 141 is fixedly connected to a ring 142. One end of a push rod 143 is hinged on the ring 142, and the other end of the push rod 143 is hinged to a side plate 144. The side plate 144 is slidably set on the workbench 2, and a pressure plate 145 is slidably set on the side plate 144. An elastic member 146 is provided between the pressure plate 145 and the side plate 144.

[0061] It should be noted that the elastic member 146 is a spring, and the cylinder 141 drives the ring 142 to move upward, so that in the process of the upward movement of the ring 142, the push rod 143 pushes the side plate 144 to move in the direction close to the workbench 2, so that in the process of the movement of the side plate 144, the scraps can extend between the side plate 144 and the pressure plate 145, and under the action of the spring, the edge position of the scraps can be clamped and fixed by the side plate 144 and the pressure plate 145.

[0062] It should also be noted that the end of the side panel 144 is arranged with an inclined surface, and a notch with an inclined surface on the ground is opened on the workbench 2, so that when the side panel 144 moves in the direction close to the workbench 2, the side panel 144 can first move upward at an angle for a distance, so that the contact part between the side panel 144 and the pressure plate 145 is on the same horizontal plane as the scrap, so that the edge position of the scrap can be clamped and fixed by the side panel 144 and the pressure plate 145 during its movement.

[0063] For further information, please refer to the attached manual. Fig.11 A limit assembly 15 is provided on one side of the workbench 2, and the limit assembly 15 includes a side groove 151. The side groove 151 is opened on the side of the workbench 2. A sliding bar 152 is slidably provided in the side groove 151, and an elastic member 153 is provided at the bottom of the sliding bar 152. A fixed block 154 is fixedly provided at the bottom of the side plate 144, and the fixed block 154 is slidably provided on the sliding bar 152.

[0064] It should be noted that the elastic member 153 is a spring, which can limit the side plate 144 through the cooperation of the side groove 151, the sliding bar 152, the spring and the fixed block 154, so that the side plate 144 always maintains a horizontal state during the movement.

[0065] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
