Description

Technical Field

[0001] The utility model relates to the technical field of woodworking machinery, in particular to a wood positioning and processing device. Background Art

[0002] The mortise and tenon joint is an ancient and traditional connection method for wood and bamboo products.

[0003] Among them, before opening the mortise and tenon on the wood, it is necessary to manually or use equipment to position the wood at a certain angle, then use a tenon cutter to cut the wood into a plane at a certain angle, and then use a drill to drill holes of the required depth and width. For example, frame structures such as door frames and window frames generally use a 45° bevel connection method, so that the tenon and the mortise form a 45° bevel connection method.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0036] See also Figure 1 and Figure 2 The utility model discloses a wood positioning and processing equipment, which includes a workbench 1 and a limiting assembly 2 arranged on the workbench 1. Specifically, a guide groove 11 is provided on the workbench 1; the limiting assembly 2 includes a limiting support plate 21 and a limiting end plate 22, wherein the limiting support plate 21 is arranged on the surface of the workbench 1, and the limiting support plate 21 has a first end and a second end, the first end is rotatably connected to the workbench 1, and the second end is slidably connected to the guide groove 11, so that the angle of the limiting support plate 21 can be adjusted; at the same time, the limiting support plate 21 also has a first abutment surface. In addition, the limiting end plate 22 is rotatably connected to the first end, and the limiting end plate 22 has a second abutment surface; wherein the second abutment surface is used to be set at an angle with the first abutment surface during the rotation of the limiting end plate 22.

[0037] On the basis of this structure, when using the wood positioning and processing equipment of the utility model, the wood 4 can be accurately positioned, and the end of the wood 4 can be processed into different tenon angles; or the wood 4 can be positioned without changing the original tenon style and the maximum processable range of the tenon, which is conducive to the processing of short wood 4 with oblique tenons of various angles.

[0038] Specifically, when an angle is processed on the end of the wood 4, for example, the angle is 45°, the second end of the limiting support plate 21 can be slid in the guide groove 11 on the workbench 1 until the first support surface forms an angle of 45° with the front end surface of the workbench 1, and then the wood 4 is sent into the workbench 1 along the first support surface, and then the limiting end plate 22 is rotated relative to the limiting support plate 21 until the second support surface is set at an angle with the first support surface, and then the other side of the wood 4 is abutted against the second support surface, so that the wood 4 can be positioned at an angle of 45° with the front end surface of the workbench 1.

[0039] If the angle of the wood 4 to be processed is 60°, the second end of the limiting support plate 21 can be slid in the guide groove 11 on the workbench 1 until the first support surface and the front end surface of the workbench 1 form an angle of 60°. After the wood 4 is fed into the workbench 1 along the first support surface, the wood 4 is positioned at an angle of 60° with the front end surface of the workbench 1.

[0040] It should be noted that, after the wood 4 and the front end face of the workbench 1 are positioned at a certain angle, the tenon cutter approaches the front end face of the workbench 1 and cuts off the portion of the wood 4 protruding from the front end face, so that the front end face of the wood 4 forms a connecting inclined surface at a certain angle. Then, after the tenon is cut on the connecting inclined surface of the wood 4, the two woods 4 can be connected at a certain angle through the two connecting inclined surfaces, so that the tenon and the mortise groove are firmly connected.

[0041] When the wood positioning and processing equipment needs to further process the oblique tenon on the short wood 4, it can slide the second end of the limiting support plate 21 in the guide groove 11 on the workbench 1 until the first abutment surface and the front end surface of the workbench 1 form an angle of 30° according to the angle of the oblique tenon on the wood 4, for example, when the angle is 30°, then after the wood 4 is fed into the workbench 1 along the first abutment surface, the plane where the oblique tenon on the wood 4 is located is parallel to the front end surface of the workbench 1, that is, the oblique tenon of the wood 4 is facing the front side of the workbench 1, then after the wood 4 is positioned, it is beneficial for the tenon making machine to further process the oblique tenon of the wood 4.

[0042] With the diversification of existing building or furniture styles, when connecting wood pieces, it is often necessary to form connection end faces at different angles on the wood 4 according to the usage scenario or strength requirements. However, the existing wood 4 positioning equipment has a limit plate 21 fixed on the workbench 1, so the limit plate 21 can only position the wood 4 at one angle. If a connection end face at another angle is to be formed, another wood 4 positioning equipment is required. Similarly, when the limit plate 21 is fixed on the workbench 1, it can only position the wood 4 with the same angle of the oblique tenon. If the oblique tenon at another angle needs to be processed, another wood 4 positioning equipment is required. This will result in high processing costs and low processing efficiency.

[0043] Therefore, the utility model fixes and rotatably connects the first end of the limiting support plate 21 to the workbench 1, and slidably connects the second end of the limiting support plate 21 to the guide groove 11 of the workbench 1. Then, during the sliding process of the second end of the limiting support plate 21 in the guide groove 11, the limiting support plate 21 can rotate relative to the first end, so that the angle between the first abutment surface on the limiting support plate 21 and the front end surface of the workbench 1 can be adjusted.

[0044] Therefore, the utility model can adjust the position of the limiting support plate 21 so that different angles are formed between the first support surface and the front end surface of the workbench 1, so that the wood 4 can be cut to obtain connecting bevels of different angles after being fed into the workbench 1 along the angle of the first support surface. That is, the utility model can position the wood 4 at multiple angles through a wood positioning and processing device, so that the wood 4 can obtain connecting bevels of multiple angles after being processed, which can effectively reduce the processing cost, and the equipment is easy to debug and the processing accuracy is guaranteed.

[0045] In addition, the wood positioning and processing equipment of the present invention can also adjust the angle of the limiting plate 21 to the inclination angle of the tenon of the wood 4, so that after the wood 4 is positioned, the end face of the tenon of the wood 4 faces the tenon making machine at the front end of the workbench 1, which is conducive to the tenon making machine to perform subsequent processing on the end face of the tenon, and the limiting component 2 can position the wood 4 without changing the original tenon style and the maximum processable range of the tenon.

[0046] Furthermore, the wood positioning and processing equipment includes a detection component, specifically, the detection component includes a positioning member 12 and a position sensor 13, wherein the positioning member 12 is arranged in the guide groove 11, and the position sensor 13 is connected to the second end of the limiting plate 21, and the position sensor 13 is used to read and transmit the position signal of the positioning member 12 when the second end is slidably connected to the guide groove 11.

[0047] Based on this structure, the detection component can be a magnetic scale in the prior art, see Figure 3, wherein the positioning member 12 may be a magnetic scale, which extends along the length direction of the guide slot 11, and both ends of the magnetic scale are fixed to the side wall of the guide slot 11 by tensioning screws 121; see Figure 5 The position sensor 13 may be a magnetic read head, which is connected to the second end of the limit plate 21 and can perform magneto-electric conversion. Specifically, the magnetic read head converts the magnetization signal recorded on the magnetic scale into an electrical signal and transmits it to the detection circuit to achieve displacement measurement or position positioning.

[0048] Before positioning the wood 4, the second end of the limit plate 21 can be slid in the guide groove 11 according to the angle of the wood 4 to be processed. The read head follows the second end to slide in the guide groove 11, and the read head can detect the position of the second end in real time and guide the second end to slide to a specific position so that the first abutment surface of the limit plate 21 forms a certain angle with the front end surface of the workbench 1.

[0049] It should be noted that the magnetic scale has high measurement accuracy, which can improve the position accuracy of the limit plate 21, thereby improving the processing accuracy of the wood 4. In addition, the magnetic scale and the reading head are non-contact installed, and there is no wear between the two, which can extend the service life of the detection component.

[0050] In addition, the positioning member 12 can also be a plurality of detection pieces, and the plurality of detection pieces are arranged at intervals in the guide groove 11. When the second end slides in the guide groove 11, the plurality of detection pieces trigger the position sensor 13 at different positions respectively. Each time the position sensor 13 is triggered, it transmits a position signal, so that the second end can be guided to stop at different positions so that the first abutment surface of the limit support plate 21 forms different angles with the front end surface of the workbench 1.

[0051] Further, see Figure 4 A driving member is provided on the workbench 1, and a power output end of the driving member is connected to the limiting end plate 22.

[0052] On the basis of this structure, the limit end plate 22 is rotatably connected to the power output end of the driving member through the first rotating shaft, and the limit end plate 22 is rotatably connected to the limit support plate 21 through the second rotating shaft; the driving member can drive the limit end plate 22 to rotate relative to the limit support plate 21 through the power output end, and adjust the angle between the first support surface and the second support surface.

[0053] After the wood 4 is fed into the workbench 1 along the first abutment surface, the limiting end plate 22 can be driven by the driving member to rotate relative to the limiting abutment plate 21 until the second abutment surface is set at an angle to the first abutment surface. Since the adjacent two side surfaces on the regular wood 4 are usually connected at a right angle, in order to ensure that the second abutment surface can abut against the wood 4, the angle between the second abutment surface and the first abutment surface is not greater than 90°.

[0054] Specifically, when the angle between the second abutting surface and the first abutting surface is equal to 90° (at this time Figure 2 The end of the limiting end plate 22 protrudes from the first abutment surface, and the end of the limiting end plate 22 can abut against the end of the wood 4, so the limiting abutment plate 21 and the limiting end plate 22 can limit the two sides of the wood 4 at the same time; therefore, when the pressing device above the wood 4 presses down the wood 4, the limiting assembly 2 can limit the movement of the wood 4 from two directions, thereby improving the positioning accuracy of the wood positioning processing equipment and preventing the short wood 4 from being cut too much.

[0055] When the angle between the second abutment surface and the first abutment surface is less than 90°, the limiting end plate 22 can push the wood 4 toward the workbench 1 along the first abutment surface, reducing the portion of the wood 4 protruding from the front end of the workbench 1 and preventing the short wood 4 from being further cut shorter.

[0056] When the angle between the second abutting surface and the first abutting surface is greater than 90°, the end of the limiting end plate 22 is located inside the first abutting surface, and there is a distance between the end of the limiting end plate 22 and the side of the wood 4 and the limiting end plate 22 cannot abut against the wood 4. Therefore, after the wood 4 is pressed by the pressing device, the limiting end plate 22 can be driven by the driving member to rotate relative to the limiting abutting plate 21 to return to its original position, so that the angle between the second abutting surface and the first abutting surface is greater than 90°. At this time, when the limiting end plate 22 does not protrude from the front end of the workbench 1, it can avoid affecting the advancement of the tenon cutter.

[0057] Among them, the driving member can be a combination of a motor and a transmission member, and the transmission member can transmit the rotation of the motor to the limit end plate 22, so that the limit end plate 22 rotates relative to the limit support plate 21; in addition, the transmission member can also be a rotating electromagnet, whose power output end is connected to the limit end plate 22, and can drive the limit end plate 22 to rotate within a certain angle when power is on, and can drive the limit end plate 22 to rotate back to its original position after power is off.

[0058] Furthermore, the workbench 1 is provided with an adjustment component 3, and the adjustment component 3 is used to fine-tune the limit end plate 22. Figure 4 The adjustment component 3 includes a slide seat 31 fixedly connected to the limiting support plate 21 and a slider 32 slidably connected to the slide seat 31, wherein the slider 32 is also provided with a mounting seat 321, the driving member is connected to the mounting seat 321, and the slider 32 is used to slide under the action of external force and drive the driving member to move.

[0059] On the basis of this structure, when positioning the wood 4, the power output end of the driving member can first drive the limiting end plate 22 to rotate relative to the limiting support plate 21 until the second support surface is against the end surface of the wood 4. When the cutting length of the wood 4 needs to be adjusted, force can be applied to the slider 32. Through the sliding action between the slider 32 and the slide seat 31, the slider 32 can drive the driving member as a whole to move toward the rear end of the workbench 1. In the process of moving, the driving member drives the limiting end plate 22 through the power output end to slightly push the wood 4 toward the rear end of the workbench 1, thereby reducing the length of the wood 4 protruding from the front end of the workbench 1.

[0060] It should be noted that the driving member can also be used to directly drive the limiting end plate 22 to adjust the cutting length, for example, the power output end of the driving member drives the limiting end plate 22 to rotate relative to the limiting support plate 21, and reduces the angle between the first support surface and the second support surface. In this process, the limiting end plate 22 can also push the wood 4 to the rear end of the workbench 1. However, when the driving member directly drives the limiting end plate 22 to adjust, the rotation amplitude of the limiting end plate 22 is large, which is easy to push the wood 4 to the rear end of the workbench 1 by a large margin, resulting in incomplete cutting of the oblique tenon.

[0061] Therefore, in this embodiment, by providing the adjustment component 3, the limiting end plate 22 can be fine-tuned to reduce the rotation amplitude of the limiting end plate 22, thereby improving the accuracy of adjusting the cutting length and ensuring that the short wood 4 will not be cut too short.

[0062] Furthermore, the driving member includes a cylinder 23 and a piston rod 24, one end of the piston rod 24 is slidably disposed in the cylinder 23; Figure 4 The limiting end plate 22 specifically includes a connecting plate segment 221 and a limiting plate segment 222, wherein the limiting plate segment 222 is connected to one side of the connecting plate segment 221, and the two ends of the connecting plate segment 221 are rotatably connected to the power output end and the first end of the piston rod 24 respectively.

[0063] On the basis of this structure, when the limiting end plate 22 is used, the power output end of the piston rod 24 moves toward the front end of the workbench 1. Since the two ends of the connecting plate segment 221 on the limiting end plate 22 are rotatably connected to the power output end of the piston rod 24 and the first end of the limiting support plate 21, respectively, the connecting plate segment 221 can be driven by the piston rod 24 to rotate relative to the limiting support plate 21, and the limiting plate segment 222 is driven by the connecting plate segment 221 to approach the wood 4. On the contrary, when the power output end of the piston rod 24 moves away from the front end of the workbench 1, the connecting plate segment 221 can be driven by the piston rod 24 to rotate relative to the limiting support plate 21 and make the limiting plate segment 222 rotate away from the wood 4.

[0064] In this way, the limiting end plate 22 can convert the movement of the piston rod 24 into rotation by setting the connecting plate section 221, and by setting the limiting plate section 222, the piston rod 24 can be driven by the connecting plate section 221 to approach or move away from the wood 4, and the limiting plate section 222 limits the wood 4 through the second abutment surface when approaching the wood 4, and will not affect the advancement of the tenon cutter when moving away from the wood 4.

[0065] Further, see Figure 5 as well as Figure 6 The slider 32 is provided with a mounting arm 322, and the adjustment assembly 3 includes an adjustment plate 33 and an adjustment screw 34. Specifically, the adjustment plate 33 is provided on one side of the slide seat 31 and is fixedly connected to the limit support plate 21, and the adjustment screw 34 passes through the adjustment plate 33 and is connected to the mounting arm 322. The adjustment screw 34 is used to drive the slider 32 to slide during the rotation process.

[0066] On the basis of this structure, the slide seat 31 and the adjustment plate 33 are fixed on the limit support plate 21 at intervals, and the adjustment screw 34 is passed through the adjustment plate 33 and connected to the mounting arm 322 on the slide block 32. Among them, a threaded hole can be set on the mounting arm 322, and the adjustment screw 34 is screwed with the threaded hole. Then, when the adjustment screw 34 rotates, the slide block 32 can slide on the slide seat 31 driven by the adjustment screw 34, and the slide block 32 approaches or moves away from the adjustment plate 33 during the sliding process; at the same time, the slide block 32 also drives the driving member to move during the sliding process, so that the limit end plate 22 can be fine-tuned.

[0067] In this way, the rotation of the adjusting screw rod 34 can drive the limiting end plate 22 to rotate slightly relative to the limiting support plate 21, thereby achieving fine adjustment of the limiting end plate 22.

[0068] Furthermore, the adjustment assembly 3 includes a limit slide 35, see Figure 6 The slider 32 is provided with a sliding groove 323 , and the limiting sliding post 35 passes through the sliding groove 323 and is connected to the sliding seat 31 , wherein the limiting sliding post 35 can be slidably connected in the sliding groove 323 .

[0069] On the basis of this structure, the slide seat 31 is fixedly connected to the limit support plate 21, and the slider 32 can slide on the slide seat 31 under the action of the adjusting screw 34, thereby driving the driving member to move as a whole, and when the driving member moves away from the front end of the workbench 1, it can drive the limit end plate 22 to slightly push the wood 4 into the workbench 1. Among them, when the slider 32 slides on the slide seat 31, the limit slide post 35 slides in the sliding groove 323, and when the limit slide post 35 slides to abut against the two ends of the sliding groove 323, the slider 32 cannot slide further.

[0070] Therefore, the limiting sliding between the limiting slide post 35 and the sliding groove 323 can narrow the adjustment range of the adjustment assembly 3, preventing the adjustment screw 34 from continuously rotating in one direction, causing the slider 32 to drive the driving member to move too much.

[0071] Furthermore, a locking seat 25 is provided at the bottom of the second end, and the locking seat 25 is arranged below the guide groove 11; wherein the second end is connected to the locking seat 25 through a locking screw 261, and the locking seat 25 is used to abut against the bottom of the workbench 1 in a locked state.

[0072] Based on this structure, a locking handle 26 is provided at the upper end of the locking screw 261, and the operator can drive the locking screw 261 to rotate by turning the locking handle 26. Since the second end of the limit plate 21 is located on the upper surface of the workbench 1, and the locking seat 25 is located below the guide groove 11, during assembly, the end of the locking screw 261 passes through the limit plate 21 and the guide groove 11 in sequence and is screwed to the locking seat 25. When the locking screw 261 rotates, the locking seat 25 can move on the locking screw 261.

[0073] It should be noted that the second end of the limiting support plate 21 is slidably connected to the guide groove 11 through the locking screw 261 and the locking seat 25. When the angle of the limiting support plate 21 needs to be changed, the locking handle 26 can be rotated to make the locking seat 25 move downward on the locking screw 261 and away from the guide groove 11. At this time, the second end of the limiting support plate 21 can slide in the guide groove 11, so that the angle of the limiting support plate 21 can be adjusted. When the second end of the limiting support plate 21 is rotated to a certain angle, the locking handle 26 can be rotated in the opposite direction to rotate the locking screw 261, thereby making the locking seat 25 move upward on the locking screw 261 and press against the bottom of the guide groove 11, so that the movement of the second end can be limited.

[0074] By setting the locking seat 25 to limit the second end of the limiting plate 21, it is possible to prevent the limiting plate 21 from rotating during the feeding process of the workbench 1, thereby preventing the feeding angle of the wood 4 from changing.

[0075] Furthermore, the second end is provided with a positioning hole 211, and correspondingly, the workbench 1 is provided with a plurality of positioning grooves. In addition, the limiting assembly 2 includes a limiting pin 27. The limiting pin 27 is used to connect the positioning hole 211 and the positioning groove when the limiting support plate 21 rotates to a certain angle.

[0076] On the basis of this structure, the positioning hole 211 passes through the upper and lower ends of the second end; multiple positioning grooves can be provided, and the multiple positioning grooves are arranged at intervals along the length direction of the guide groove 11. When the second end of the limiting support plate 21 rotates to a certain position in the guide groove 11, the first abutting surface on the limiting support plate 21 forms a certain angle with the front end surface of the workbench 1; at this time, after the limiting pin 27 passes through the positioning hole 211 on the second end and the positioning groove located at the corresponding angle position of the guide groove 11, the second end of the limiting support plate 21 is fixed at the position of the guide groove 11.

[0077] Therefore, when the wood 4 is fed in along the angle of the first abutment surface, since the second end of the limiting plate 21 is fixed by the limiting pin 27, the limiting plate 21 cannot rotate, which can ensure that the angle of the wood 4 will not change during the feeding process, thereby ensuring the processing accuracy.

[0078] Further, see Figure 5 A connecting shaft 29 and a bearing 28 are provided at the bottom of the first end, wherein the bearing 28 is pressed against the bottom of the limiting support plate 21 through a pressing plate 212, and both ends of the connecting shaft 29 are rotatably connected to the bearing 28 and the workbench 1 respectively.

[0079] On this structural basis, during assembly, the pressing plate 212 is arranged at the bottom of the bearing 28, and the pressing plate 212 is fixed to the limiting plate 21 by screws, so that the bearing 28 is pressed tightly against the bottom of the limiting plate 21; one end of the connecting shaft 29 is rotatably connected to the bearing 28, and the other end of the connecting shaft 29 is rotatably connected to the workbench 1. The connecting shaft 29 only rotates around its own axis.

[0080] The bearing 28 may be a double-row angular contact bearing 28 .

[0081] When in use, the second end of the limiting support plate 21 slides in the guide groove 11, and the first end of the limiting support plate 21 rotates on the workbench 1, so that the angle of the limiting support plate 21 can be adjusted. Therefore, the limiting support plate 21 can adjust the angle between the first abutting surface and the front end surface of the workbench 1 during the rotation process, so that after the wood 4 is fed at a certain angle, it can be positioned at the angle, and a certain angle oblique tenon is formed after being cut.

[0082] Furthermore, two groups of limit components 2 are symmetrically provided on the workbench 1. After adjusting the feeding angle of the limit support plate 21, the material can be unloaded from the left limit component 2 first, and then the tenon making machine or tenon cutter on the front side of the workbench 1 will process the positioned wood 4. At the same time, the material can be unloaded from the right limit component 2, and the tenon making machine or tenon cutter will automatically process the right wood 4 after processing the left wood 4.

[0083] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
