Description

Technical Field

[0001] The present invention relates to the field of furniture processing. Specifically, it relates to a wood positioning device for furniture processing and its usage method. Background Art

[0002] Furniture refers to a large category of utensils and facilities that are essential for humans to maintain normal life, engage in production practices, and carry out social activities. Furniture such as wardrobes, coffee tables, bookshelves, etc. are usually made of wood materials. After the furniture is completed, rubbing the color and painting it can make the surface of the furniture smooth, the wood grain clear and transparent, the luster soft, etc., which can greatly improve the texture of the furniture.

[0003] During the furniture processing, a large number of boards are required. Therefore, the wood is usually cut into sheets and then processed into the required boards according to the needs. During the cutting process of the wood, in order to prevent the wood from shifting during cutting, it is necessary to clamp and position the wood. Since the thickness of the wood is different, the distance between the fixture and the wood will also change accordingly. Therefore, in order to firmly clamp the wood without damaging the surface of the wood, it is necessary to adjust the forward stroke of the fixture according to the thickness of the wood at any time, resulting in an increased workload during the wood processing and affecting the processing efficiency.

[0004] Therefore, those skilled in the art have provided a wood positioning device for furniture processing and its usage method to solve the problems raised in the above background art. Summary of the Invention

[0005] The purpose of the present invention is to provide a wood positioning device for furniture processing and its usage method to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] According to one aspect of the invention, a wood positioning device for furniture processing is provided.

[0008] The wood positioning device for furniture processing includes a base and a controller connected to the side wall of the base. A plurality of groups of shells are sequentially arranged at intervals along the left - right direction on the top of the base. Each group of shells includes two and is arranged at the edges on the front and rear sides of the base. A chute is opened on one side of the shell away from the edge of the base and is slidably connected with a piston member. One side of the piston member away from the shell is connected with a push plate for positioning the wood. A hydraulic press for pushing the piston member to linearly move is fixedly connected to the outer side wall of the shell.

[0009] By adopting the above technical solution, when positioning the wood, the clamping force can be automatically adjusted through the pressure balance component in the piston member, avoiding the change of the clamping force when the stroke of the piston member is affected by the width of the wood.

[0010] Further, the piston member includes a sliding block which is slidably disposed in the chute. A pressure groove is formed on a side of the sliding block away from the housing, and a pressure relief hole communicating with the pressure groove is formed on a side of the sliding block close to the housing.

[0011] A push rod is disposed in the pressure groove. One side of the push rod away from the pressure relief hole extends out of the sliding block and is connected to a push plate.

[0012] A pressure balance assembly is disposed in the pressure relief hole.

[0013] An anti - rebound assembly is located on one side of the pressure groove to prevent the push rod from rebounding.

[0014] By adopting the above - mentioned technical solution, the push rod can be used to compress the pressure chamber to increase the clamping force of the push plate on the wood, and the provided pressure balance assembly can effectively prevent the wood from being crushed due to excessive clamping force.

[0015] Further, the pressure balance assembly includes two pressure relief plugs. Each pressure relief plug includes a head end and a tail end. A groove is formed in the head end, and an exhaust groove communicating with the groove is formed on an outer side wall of the tail end. Anti - detachment members are formed by protrusions at the edges of the outer side walls of the head end and the tail end.

[0016] The two pressure relief plugs are respectively plug A and plug B, and plug B is a geometric reduction of plug A by half.

[0017] Plug A is slidably disposed in the pressure relief hole, plug B is slidably disposed in plug A, the head end of plug B penetrates through plug A and extends into the pressure groove, and a compression spring is disposed between the anti - detachment member at the head end of plug B and plug A.

[0018] By adopting the above - mentioned technical solution, gas leakage can be prevented when the push rod squeezes the pressure chamber to increase the clamping force, and pressure relief can be carried out when the clamping force is too large to prevent the wood from being crushed.

[0019] Further, the anti - rebound assembly includes a guide block. Two guide blocks are symmetrically disposed in a track groove on a side of the sliding block where the pressure groove is located, with the axis of the pressure groove as the reference.

[0020] A dial block is disposed in a square groove communicating with the track groove on one side of the pressure groove. The dial block is located between the two guide blocks and is rotatably connected to the two guide blocks.

[0021] A jacking rod is disposed outside the sliding block. One end of the jacking rod is inserted into the sliding block and extends into the square groove.

[0022] By adopting the above technical solution, when the wood separates from the push plate, the push plate loses the support of the wood. Subsequently, when the pressure in the pressure chamber pushes the push rod to quickly reset, it touches the dial block, and the dial block is used to block the push rod to prevent it from quickly resetting and colliding.

[0023] Furthermore, on the outer wall of the two guide blocks close to each other, there are protrusions formed with support members for supporting the dial block, and the support members are located at the edge of the guide block away from the ejector rod.

[0024] By adopting the above technical solution, support can be provided for the dial block to ensure that the dial block can normally contact the push rod.

[0025] Furthermore, on the side of the guide block away from the pressure groove, there is a spring groove opened, and a support spring is arranged between the inner side wall of the spring groove and the track groove.

[0026] By adopting the above technical solution, the sliding block can drive the dial block to insert into the slot.

[0027] Furthermore, the width of the square groove is greater than the width of the track groove, and there is an inclined angle at the junction of the inner wall of the square groove close to the ejector rod and the inner wall away from the pressure groove.

[0028] By adopting the above technical solution, it is convenient for the dial block to contact the inclined angle when being pushed by the push rod to tilt, increasing the limiting force of the dial block on the push rod.

[0029] Furthermore, on the outer side wall of the push rod, a plurality of slots for inserting the dial block are sequentially arranged from front to back along the axial direction.

[0030] By adopting the above technical solution, the effective protection range of the anti-rebound component can be increased.

[0031] Furthermore, the push plate includes a support part and an extrusion part. The bottom of the support part is parallel to the top of the base and there is a gap left. One side of the support part is vertically and fixedly connected with the extrusion part. A plurality of rotating rollers are arranged on the sides of the support part and the extrusion part in contact with the wood.

[0032] By adopting the above technical solution, after the wood is clamped and positioned, it can move normally, facilitating continuous cutting and processing of the wood.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] 1. By means of the provided piston member, when the push plate clamps different woods, it is not necessary to change the feed stroke of the hydraulic press, and at the same time, the clamping force of the push plate on the wood is maintained to avoid damaging the wood. It can be used for continuous processing of woods with various widths, achieving the effect of reducing the workload and greatly improving the wood processing efficiency during furniture manufacturing.

[0035] 2. By means of the provided anti - rebound assembly, when the wood disengages from the push plate, the push rod can be blocked to prevent the push plate from rebounding rapidly and colliding, which can effectively reduce the damage to the piston member, lower the maintenance frequency of the positioning device, and achieve the effect of reducing the usage cost.

[0036] 3. By providing rotating rollers on the supporting part and the squeezing part, after the wood is clamped, the wood can still be fed normally, so that when the wood is continuously processed, it is not necessary to adjust the position and re - clamp, which can effectively improve the continuous processing efficiency of the wood.

[0037] According to another aspect of the present invention, there is provided a wood positioning method for furniture manufacturing, which is used for the above - mentioned wood positioning device for furniture manufacturing.

[0038] The wood positioning method for furniture manufacturing includes the following steps:

[0039] S101, Place the wood on the base;

[0040] S102, Synchronously start all hydraulic presses through the controller;

[0041] S103, The hydraulic press pushes the piston member to move so that the push plate clamps the wood;

[0060] Next, in combination with the accompanying drawings and specific embodiments, the invention will be further described:

[0061] According to one aspect of the invention, a wood positioning device for furniture processing is provided.

[0062] Referring to Figure 1 - Figure 7 , a wood positioning device for furniture processing disclosed by the present invention includes a base 1 and a controller 21 connected to the side wall of the base 1. A plurality of groups of shells 2 are sequentially arranged at intervals along the left - right direction on the top of the base 1. Each group of shells 2 includes two and is arranged at the edges on the front and rear sides of the base 1. A chute 3 is opened on one side of the shell 2 far from the edge of the base 1, and a piston member 4 is slidably connected thereto. A push plate 5 for positioning wood is connected to the side of the piston member 4 far from the shell 2. A hydraulic press 6 for pushing the piston member 4 to linearly move is fixedly connected to the outer side wall of the shell 2.

[0063] In this embodiment, the wood is placed on the push plate 5 above the base 1. Subsequently, all the hydraulic presses 6 are started through the controller 21, so that the hydraulic presses 6 push the piston members 4 to slide in the chutes 3. Finally, the piston members 4 push the push plates 5 to clamp the wood. After the wood is positioned, the wood can be cut into pieces by a cutting machine. Refer to Figure 1 It can be found that the push plates 5 for clamping the wood are symmetrically distributed on the top of the base 1. Therefore, when the push plates 5 clamp the wood, the wood will be centered, thus achieving the positioning effect of the wood, improving the processing accuracy of the wood. At the same time, in Figure 1 a protective cover 22 can also be seen, which can be used to provide protection for the plurality of groups of shells 2.

[0064] During the movement of the piston member 4, the extrusion part 52 of the push plate 5 will contact and squeeze the side wall of the wood, and at this time, the side wall of the wood will also exert a pressure on the extrusion part 52 to prevent the extrusion part 52 from moving. As the piston member 4 continues to move, the sliding block 41 is pushed by the hydraulic press 6 to continue approaching the wood, while the push rod 42 cannot continue to advance due to the support of the extrusion part 52. At this time, the push rod 42 will be pressed into the pressure groove 7, so that the gas in the pressure groove 7 is squeezed. The squeezed gas will be discharged through the pressure relief hole 8. At the same time as the gas is discharged, the flowing gas will also push the plug A 431 to move, and then the plug A 431 blocks the pressure relief hole 8, resulting in the gas being unable to continue to be discharged. At this time, the push rod 42 continues to squeeze the space in the pressure groove 7, which will increase the pressure in the pressure groove 7, thereby increasing the thrust exerted on the push rod 42. Therefore, the clamping force of the push plate 5 for clamping the wood will be increased, making the clamping effect of the wood positioning device on the wood better.

[0065] As the clamping force increases, the pressure on the wood also increases. To avoid damaging the surface of the wood, a compression spring is provided between the plug body A431 and the plug body B432. When the pressure in the pressure groove 7 is greater than the supporting force of the compression spring, the air pressure will push the plug body B432 to move and compress the compression spring. When the pressure relief hole 8 of the plug body B432 contacts the groove 11 of the plug body A431, the grooves 11 of the plug body A431 and the plug body B432 are connected. At this time, the gas can be discharged through the groove 11 to complete pressure relief, effectively avoiding the wood being crushed when the clamping force is too large and improving the quality of the wood.

[0066] Among them, the above-mentioned controller 21 adopts a commercially available PLC controller to synchronously control all hydraulic presses 6 through a numerical control program.

[0067] In a further preferred embodiment of the present invention, as Figure 3 - Figure 4 shown, the piston member 4 includes a sliding block 41, the sliding block 41 is slidably arranged in the sliding groove 3, a pressure groove 7 is formed on one side of the sliding block 41 away from the housing 2, and a pressure relief hole 8 communicating with the pressure groove 7 is formed on one side of the sliding block 41 close to the housing 2;

[0068] A push rod 42 is arranged in the pressure groove 7, and one side of the push rod 42 away from the pressure relief hole 8 extends out of the sliding block 41 and is connected to the push plate 5;

[0069] A pressure balance assembly 43 is arranged in the pressure relief hole 8;

[0070] An anti-rebound assembly 44 is located on one side of the pressure groove 7 to prevent the push rod 42 from rebounding.

[0071] In this embodiment, since the processed wood will be customized according to the style of the furniture, the widths of the processed wood will be different. When the width of the wood increases and the stroke of the hydraulic press 6 remains unchanged, the pressure exerted by the push plate 5 on the wood will be too large, easily damaging the wood and resulting in waste and loss of the wood. Therefore, in order to avoid the push plate 5 from excessively squeezing the wood, it is necessary to adjust the extension stroke of the hydraulic press 6. As a result, when processing woods of different widths, it is necessary to adjust the extension stroke of the hydraulic press 6 according to the wood, making the clamping of the wood cumbersome and reducing the processing efficiency.

[0072] Therefore, the sliding block 41 and the push rod 42 are provided. When the wood is at the minimum value within the effective clamping range, the push plate 5 is in normal contact with the wood and is squeezed by the wood to make the push rod 42 slide into the pressure groove 7 to compress the air in the pressure groove 7. When the air pressure is less than the supporting force of the compression spring, a continuous and stable thrust can be applied to the push rod 42 to clamp the wood with the push plate 5.

[0073] When the width of the wood increases, the push rod 42 is squeezed and the length of the push rod 42 sliding into the pressure groove 7 increases. At this time, the air pressure increases. When the air pressure is greater than the supporting force of the compression spring, the compression spring is squeezed to make the plug body B432 slide to complete the pressure relief, thereby preventing the push plate 5 from applying excessive pressure on the wood and causing damage to the wood, so that the hydraulic press 6 does not need to change the stroke when clamping wood of different widths and will not crush the wood.

[0074] In a further preferred embodiment of the present invention, Figure 4 and Figure 6 As shown, the pressure balance assembly 43 includes two pressure relief plugs, and the pressure relief plug includes a head end 9 and a tail end 10, wherein the head end 9 is provided with a groove 11, and the outer wall of the tail end 10 is provided with an exhaust groove 12 connected to the groove 11, and the outer wall edges of the head end 9 and the tail end 10 are both convexly formed with an anti-slip piece 13;

[0075] The two pressure relief plugs are plug body A431 and plug body B432, wherein the plug body B432 is half the size of the plug body A431;

[0076] The plug body A431 is slidably set in the pressure relief hole 8, and the plug body B432 is slidably set in the plug body A431. The head end 9 of the plug body B432 penetrates the plug body A431 and extends into the pressure groove 7. A compression spring is set between the anti-slip part 13 at the head end 9 of the plug body B432 and the plug body A431.

[0077] In this embodiment, since a compression spring is provided between the plug body A431 and the plug body B432, when the compression spring is not subjected to pressure, the compression spring will push the plug body B432 away from the plug body A431, but the diameter of the anti-slip member 13 of the plug body B432 is too large, so that the plug body B432 cannot slip out of the plug body A431. At this time, the exhaust groove 12 of the plug body B432 is blocked by the plug body A431, so that the groove 11 of the plug body A431 and the plug body B432 is disconnected, so that the gas cannot be discharged through the plug body B432. Therefore, when the plug body A431 blocks the pressure relief hole 8, as long as the air pressure in the pressure groove 7 is not greater than the supporting force of the compression spring, the air cannot be discharged, and the compressed gas will continue to apply thrust to the push rod 42, so that the push plate 5 is more stable when clamping the wood.

[0078] participate Figure 4 It can be found that annular grooves for avoiding the anti-dropping part 13 are also provided at the two openings of the pressure relief hole 8. Therefore, in order to improve the sealing performance when the plug body A431 blocks the pressure relief hole 8, a sealing ring (not marked in the figure) can be connected in the annular groove to effectively prevent air leakage.

[0079] In a further preferred embodiment of the present invention, Figure 4 andFigure 5 As shown, the anti-rebound component 44 includes a guide block 441. The sliding block 41 is provided with a track groove 14 on one side of the pressure groove 7. Two guide blocks 441 are symmetrically arranged in the track groove 14 with the axis of the pressure groove 7 as the reference.

[0080] A shifting block 442. A square groove 15 communicating with the track groove 14 is provided on one side of the pressure groove 7. The shifting block 442 is arranged in the square groove 15. The shifting block 442 is located between the two guide blocks 441 and is rotatably connected to the two guide blocks 441.

[0081] A ejector rod 443. The ejector rod 443 is arranged on the outer side of the sliding block 41. One end of the ejector rod 443 is inserted into the sliding block 41 and extends into the square groove 15.

[0082] In this embodiment, when the wood is continuously processed, it will continuously feed to provide sufficient processing length for cutting. As the length of the wood decreases, a group of push plates 5 on the side away from the cutting machine will separate from the wood, resulting in the push plates 5 losing the support of the wood and being unable to continue supporting the push rod 42. The air pressure in the pressure groove 7 will push the push rod 42 to quickly reset, causing the push rod 42 to impact the sliding block 41 and cause damage.

[0083] Therefore, in order to prevent the push rod 42 from hitting the sliding block 41 when it loses the support of the wood, a shifting block 442 is arranged on one side of the pressure groove 7. When the push rod 42 is quickly reset under the action of air pressure, it will apply a thrust to the shifting block 442, causing the shifting block 442 to rotate around the connection with the guide block 441, so that the tail end of the shifting block 442 enters the square groove 15 and contacts the inner wall of the square groove 15. The inner wall of the square groove 15 provides support for the shifting block 442, making the shifting block 442 unable to continue sliding. Subsequently, the push rod 42 is blocked by the shifting block 442, and the position of the push plate 5 is fixed, effectively preventing the push rod 42 from rebounding.

[0084] When the shifting block 442 enters the square groove 15, the shifting block 442 will simultaneously lift the ejector rod 443, so that one end of the ejector rod 443 extends out of the sliding block 41 to form a convex point. Subsequently, after the wood processing is completed, the hydraulic press 6 pulls the sliding block 41 to reset, so that the distance between the sliding block 41 and the inner side wall of the chute 3 gradually decreases. The inner side wall of the chute 3 is used to squeeze the ejector rod 443 to press the ejector rod 443 back into the sliding block 41. At this time, the ejector rod 443 will push the shifting block 442 out of the square groove 15. Subsequently, the unsupported shifting block 442 will drive the two guide blocks 441 on both sides to slide in the track groove 14 under the extrusion of the push rod 42. Finally, the push rod 42 loses the support of the shifting block 442 and can be normally reset.

[0085] In a further preferred embodiment of the present invention, as Figure 7As shown, on the outer wall of the two guide blocks 441 close to each other, a support member 16 for supporting the dial block 442 is formed by protrusion, and the support member 16 is located at the edge of the guide block 441 away from the ejector rod 443.

[0086] In this embodiment, by providing the support member 16, support can be provided to the dial block 442 when the push rod 42 presses the dial block 442 due to being pressed into the pressure groove 7, so as to prevent the dial block 442 from getting stuck in the square groove 15 when the push rod 42 is pressed into the pressure groove 7.

[0087] In a further preferred embodiment of the present invention, as Figure 5 shown, a spring groove 17 is formed on the side of the guide block 441 away from the pressure groove 7, and a support spring is arranged between the inner side wall of the spring groove 17 and the track groove 14.

[0088] In this embodiment, when the dial block 442 completely enters the track groove 14, it will lose contact with the push rod 42, resulting in the inability of the dial block 442 to effectively hold the push rod 42 when the push rod 42 pops out. Therefore, a support spring is arranged between the guide block 441 and the track groove 14, and the guide block 441 can be pushed to reset by the support spring so that the dial block 442 can continuously contact the push rod 42, making the operation of the anti-backlash assembly 44 more stable.

[0089] In a further preferred embodiment of the present invention, as Figure 5 shown, the width of the square groove 15 is greater than the width of the track groove 14, and a bevel 18 is arranged at the junction of the inner side wall of the square groove 15 close to the ejector rod 443 and the inner side wall away from the pressure groove 7.

[0090] In this embodiment, when the tail end of the dial block 442 enters the square groove 15, it will contact the edge of the square groove 15 and be damaged, which will cause indentations on the dial block 442 during long-term use, resulting in the inability of the ejector rod 443 to effectively push the dial block 442 out of the square groove 15 when the piston member 4 is reset.

[0091] Therefore, a bevel 18 is arranged at the junction of the inner side wall of the square groove 15 close to the ejector rod 443 and the inner side wall away from the pressure groove 7, which can prevent the dial block 442 from being damaged during use, make the operation of the anti-backlash assembly 44 more stable, reduce the maintenance frequency, and lower the use cost.

[0092] In a further preferred embodiment of the present invention, as Figure 4 shown, a plurality of slots 19 for inserting the dial block 442 are sequentially arranged on the outer side wall of the push rod 42 along the axial direction from front to back.

[0093] In this embodiment, as the width of the wood increases, the length of the push rod 42 pressed into the pressure groove 7 also increases, which causes the length of the push rod 42 moving relative to the dial block 442 to increase. Therefore, in order to reduce the rebound distance of the push rod 42 and weaken the impact generated when the push rod 42 rebounds, a plurality of slots 19 are provided on the push rod 42, so that when the push rod 42 rebounds, the slots 19 can quickly engage with the dial block 442, effectively reducing the damage generated when the push rod 42 rebounds.

[0094] In a further preferred embodiment of the present invention, as Figure 3 shown, the push plate 5 includes a support portion 51 and an extrusion portion 52. A gap is reserved in parallel between the bottom of the support portion 51 and the top of the base 1. One side of the support portion 51 is vertically and fixedly connected with an extrusion portion 52. A plurality of rotating rollers 20 are provided on the sides of the support portion 51 and the extrusion portion 52 in contact with the wood.

[0095] In this embodiment, the wood will gradually become shorter during processing. Therefore, in order to facilitate subsequent processing and adjust the position of the wood according to requirements, it is necessary to frequently disassemble and assemble the wood, reducing the processing efficiency. Therefore, a plurality of rotating rollers 20 are provided on the push plate 5, so that after the push plate 5 clamps the wood, the wood can still be fed flexibly, effectively improving the efficiency of continuous processing of the wood.

[0096] During the wood processing, wood chips will be generated due to cutting. When the wood chips accumulate on the base 1, they will affect the movement of the support portion 51 of the push plate 5. Therefore, a gap is reserved between the support portion 51 and the top of the base 1, which can effectively prevent the wood chips from interfering with the movement of the push plate 5.

[0097] According to another aspect of the present invention, a wood positioning method for furniture processing is provided, which is used for the above-mentioned wood positioning device for furniture processing.

[0098] Please refer to Figure 8 , a wood positioning method for furniture processing disclosed by the present invention includes the following steps:

[0099] S101, placing the wood on the base 1;

[0100] S102, synchronously starting all hydraulic presses 6 through the controller;

[0101] S103, the hydraulic press 6 pushes the piston member 4 to move so that the push plate 5 clamps the wood;

[0102] S104, automatically adjusting the clamping force on the wood through the pressure balance assembly 43;

[0103] S105, cutting the wood and feeding the wood after the cutting is completed;
