Description

Technical Field

[0001] The utility model relates to the technical field of wood product processing, in particular to a four-side saw for a door leaf. Background Art

[0002] As a product commonly used in the construction industry, wooden doors are structures that achieve relative closure and opening of spaces. They are usually composed of door frames, hinges, door leaves and other structures, and are installed in door openings of buildings.

[0003] The existing door panels on the market are usually rectangular structures. During processing, a door panel larger than the required door panel size is usually first processed, and then the four sides are sawed to obtain a door panel that meets the size requirements. At present, the methods of sawing the four sides of the door panel on the market include manual sawing and machine sawing. Although manual sawing is low-cost, there will be a shaking problem when the saw is held manually, resulting in poor sawing accuracy, affecting the processing quality of the door panel, and its sawing efficiency is low. The machine sawing uses a sawing machine for sawing. Although the sawing efficiency is improved, a circular saw machine is usually used for sawing, such as the wooden door circular saw machine disclosed in patent CN104526770A, which has a working platform for placing wooden boards and a circular saw blade arranged on one side of the working platform, and a clamping device is arranged on the other side of the working platform. The clamping device includes a positioning rod, a straight rod, an arc rod and a handle connected in sequence. The positioning rod is placed on the wooden board, the straight rod is fixed on the positioning rod, the arc rod is hinged on the straight rod, and the hand rod is fixed on the arc rod. On the upper side, a pressure plate is fixed on each of the two sides of the arc rod, and the lower edge of the pressure plate is straight. The sides of the two pressure plates are opposite to each other and the width between the two pressure plates is consistent with the preset door panel slot width. During processing, the two pressure plates are arranged above the preset door panel slot, and the preset door panel slot is located between the two pressure plates. Through the hinged relationship between the arc rod and the straight rod, the pressure plate fixed on the arc rod is pressed toward the wooden board, so that the lower edge of the pressure plate is pressed on the wooden board. At this time, the circular saw blade begins to contact the wooden board and moves toward the pressure plate to realize the sawing of the wooden board. Although the above-mentioned circular saw machine can meet the sawing needs, in the actual processing process, it is necessary to manually align the different sides of the door leaf plate with the circular saw blade, which not only requires multiple clamping, but also requires multiple measurements and debugging. In addition, since each side is sawed separately, it will lead to the accumulation of processing errors, and there is still a problem of ultimately affecting the processing accuracy.

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the following embodiments are combined with the attached Figure 1 To Attachment Figure 6 The technical solution provided by the utility model is described in detail, but the following content is not intended to limit the utility model.

[0030] Figure 1 It is a structural diagram of an embodiment of a door leaf four-side saw of the utility model; Figure 2 This is a diagram of the internal structure of a four-side saw for door leafs of the utility model. Figure 1 and Figure 2 As shown, the four-side door leaf saw provided in this embodiment includes: a frame 1, an automatic centering workbench 2, an upper clamping assembly 3 and a sawing assembly 4.

[0031] Specifically, the frame 1 includes a base frame 11 and a top frame 12. At this time, the top frame 12 is arranged on the base frame 11 and is placed horizontally above the base frame 11, and a number of columns are arranged between the base frame 11 and the top frame 12. The columns are used to provide stable support for the top frame 12, ensuring that the top frame 12 has a relatively stable load-bearing capacity, thereby providing conditions for the subsequent installation of the upper clamping assembly 3 and the end sawing portion 42.

[0032] Figure 3 This is a structural diagram of an automatic centering workbench for a four-side saw of a door leaf according to the utility model. Figure 2 and Figure 3 As shown, the automatic centering workbench 2 is arranged on the base frame 11. At this time, the automatic centering workbench 2 includes a platform frame 21 and a platform centering driving member 22. Two platform frames 21 are set, and the two platform frames 21 are arranged in one direction, and the arrangement direction of the platform frames 21 is the loading and unloading direction of the door leaf plate. In addition, the two platform frames 21 are parallel to each other and arranged at intervals, so that during subsequent sawing, the two sides of the door leaf plate can be supported in the length direction by the two platform frames 21, ensuring stability during the sawing process. In addition, a platform centering driving member 22 is arranged between the two platform frames 21 and the frame 1. At this time, the movement direction of the platform centering driving member 22 is set to the direction along which the two platform frames 21 approach or move away from each other, so that when the platform centering driving member 22 moves, it can drive the two platform frames 21 to move closer or farther from each other, thereby realizing the adjustment of the spacing between the two platform frames 21, adapting to the processing requirements of door leaves of different widths, and also providing conditions for the centering adjustment of the two platform frames 21.

[0033] Figure 4 This is a structural diagram of the upper clamping assembly of a door leaf four-side saw of the utility model. Figure 2 and Figure 4 As shown, the upper clamping assembly 3 is arranged on the top frame 12 and placed horizontally above the platform frame 21. At this time, the upper clamping assembly 3 includes a lower clamping driver 31 and a lower clamping plate 32. The lower clamping driver 31 is arranged vertically downward in the vertical direction, and the lower clamping plate 32 is installed on the driving shaft of the lower clamping driver 31, so that during sawing processing, the lower clamping plate 32 can be driven down by the lower clamping driver 31 to achieve the clamping of the door leaf plate to be processed, thereby preventing the door leaf plate from moving during the sawing process and affecting the processing accuracy.

[0034] Figure 5 It is a structural diagram of the end sawing portion of a four-side saw for a door leaf of the utility model; Figure 6 This is a structural diagram of the side sawing portion of a door leaf four-side saw of the utility model. Figure 2 , Figure 5 as well as Figure 6As shown, the sawing assembly 4 includes sawing parts 41 on both sides and sawing parts 42 at both ends. The sawing parts 41 on both sides are respectively arranged on the two platforms 21 and reciprocate along the arrangement direction of the platforms 21, so that the sawing parts 41 on both sides can move with the corresponding platforms 21 to achieve sawing processing of door panels of different widths and meet the dynamic adjustment requirements. In addition, the sawing parts 42 at both ends are both placed horizontally above the platform 21 and are respectively located at the two ends of the platform 21, so that the sawing parts 42 at both ends can saw the two ends of the door panel placed on the platform 21. At the same time, the sawing parts 42 at both ends reciprocate in a direction perpendicular to the arrangement direction of the platform 21, that is, the sawing directions of the sawing parts 42 at both ends are perpendicular to the sawing directions of the sawing parts 41 at both sides, thereby forming a rectangular frame to meet the sawing requirements of rectangular door panels. At the same time, the sawing parts 41 on both sides can work simultaneously, and the sawing parts 42 at both ends can also work simultaneously, which not only improves the processing efficiency, but also makes the number of sides sawed separately smaller, thereby reducing the accumulation of processing errors, further improving the processing accuracy of the door leaf, and improving the quality of the door leaf.

[0035] More specifically, the automatic centering workbench 2 is also provided with a lifting conveyor belt 5. At this time, the two platforms 21 are provided with lifting conveyor belts 5 arranged in the same direction, so that the lifting conveyor belt 5 can also move with the platform frame 21 to meet the conveying requirements of door leaf plates of different widths. In addition, each lifting conveyor belt 5 includes a conveying lifting driver 51 and a conveyor belt body 52. ​​During installation, the lifting driver is installed on the corresponding platform frame 21 in the vertical direction, and the conveyor belt body 52 is installed on the corresponding lifting driver. The lifting driver drives the conveyor belt body 52 to be lifted and lowered in the vertical direction to adjust the height of the conveyor belt body 52. ​​That is, when loading and unloading the door leaf plate, the lifting driver can lift the conveyor belt body 52 to the top of the platform frame 21 so that the conveyor belt body 52 contacts the door leaf plate to meet the conveying requirements. When the door leaf plate needs to be sawed, the lifting driver lowers the conveyor belt body 52 to the bottom of the platform frame 21 so that the platform frame 21 can contact the door leaf plate to provide stable support for the door leaf plate. It is worth pointing out that the conveyor belt body 52 can be a structure including a conveyor frame, a conveyor belt, a conveyor wheel and a conveyor driver. The conveyor frame is installed on the corresponding lifting driver, and conveyor wheels are provided at both ends of the conveyor frame. The conveyor belt is wound around the two conveyor wheels. The conveyor driver is installed on the conveyor frame and is power-connected to a conveyor wheel. The conveyor belt is driven to move by the conveyor driver to realize the transportation of the door leaf panel placed on the conveyor belt.

[0036] More specifically, the platform centering drive member 22 for driving the two platform frames 21 to move further includes a centering rail 221, a centering driver 222, a first centering screw rod 223, a second centering screw rod and two centering screw blocks. During installation, the centering rail 221 is installed on the base frame 11 along a direction perpendicular to the arrangement direction of the platform frames 21, so that the arrangement direction of the centering rail 221 is the direction in which the two platform frames 21 approach or move away. At this time, both platform frames 21 are slidably arranged on the centering rail 221, and the centering rail 221 provides a guide for the two platform frames 21 to approach or move away. In addition, the first centering screw rod 223 and the second centering screw rod are connected in an end-to-end manner, and the thread directions of the first centering screw rod 223 and the second centering screw rod are opposite, so that the rotation directions of the first centering screw rod 223 and the second centering screw rod are opposite. The two pairs of centering screw blocks are respectively threadedly sleeved on the first pair of centering screw rods 223 and the second pair of centering screw rods. At the same time, the two pairs of centering screw blocks are respectively fixedly installed on the two platform frames 21, and the centering driver 222 is installed on the base frame 11 and is dynamically connected to the first pair of centering screw rods 223 or the second pair of centering screw rods, so that when the centering driver 222 is actuated, it can drive the first pair of centering screw rods 223 and the second pair of centering screw rods to rotate. Since the rotation directions of the first pair of centering screw rods 223 and the second pair of centering screw rods are opposite, the movement directions of the two pairs of centering screw blocks can be opposite, that is, the two pairs of centering screw blocks can approach or move away from each other, thereby driving the corresponding two platform frames 21 to move closer or farther. In addition, since the first pair of centering screw rods 223 and the second pair of centering screw rods rotate synchronously, the two platform frames 21 also move synchronously, thereby realizing the centering adjustment of the two platform frames 21, and the structural design is more reasonable.

[0037] More specifically, two groups of upper clamping assemblies 3 for clamping the door leaf plate are provided. At this time, the two groups of upper clamping assemblies 3 are respectively set as a fixed clamping assembly 33 and a movable clamping assembly 34, and the fixed clamping assembly 33 is fixed on the top frame 12, while the movable clamping assembly 34 can be moved on the top frame 12, so as to adjust the distance between the fixed clamping assembly 33 and the movable clamping assembly 34 to meet the clamping requirements of door leaves of different lengths. In addition, the fixed clamping assembly 33 and the movable clamping assembly 34 both include a hanger 331, a clamping adjustment track 332, a clamping adjustment slide 333 and a clamping adjustment drive assembly 334, and the hanger 331 is installed at the bottom of the top frame 12 as a mounting carrier for subsequent structures. Furthermore, the clamping adjustment track 332 is installed at the lower part of the hanger 331, and the clamping adjustment track 332 is installed along a direction perpendicular to the arrangement direction of the platform frame 21, so that the arrangement direction of the clamping adjustment track 332 is consistent with the moving direction of the platform frame 21 during the centering adjustment, and two clamping adjustment slides 333 are provided, and the two clamping adjustment slides 333 are both slidably arranged on the clamping adjustment track 332, so that the two clamping adjustment slides 333 can move on the clamping adjustment track 332, thereby adjusting the distance between the two clamping adjustment slides 333, so as to meet the clamping requirements of door panels of different widths. In addition, the clamping adjustment drive assembly 334 is arranged at the lower part of the hanger 331, and the clamping adjustment drive assembly 334 is power-connected to the two clamping adjustment slides 333, so that the two clamping adjustment slides 333 can be driven by the same clamping adjustment drive assembly 334, which provides conditions for the subsequent centering adjustment of the two clamping adjustment slides 333. At this time, a pressing driver 31 is installed on each pressing and adjusting slide plate 333, so that the pressing driver 31 for pressing the door leaf plate can move along with the pressing and adjusting slide plate 333 to achieve the pressing of door leaf plates of different widths.

[0038] More specifically, in order to ensure that the movable clamping assembly 34 can move on the top frame 12, the movable clamping assembly 34 also includes a longitudinal sliding assembly. When installed, the longitudinal sliding assembly is arranged between the top frame 12 and the corresponding hanger 331, so that the longitudinal sliding assembly can serve as a structure for the hanger 331 to move on the top frame 12. In addition, the longitudinal sliding assembly includes a longitudinal clamping rail 341, a longitudinal clamping slide plate 342, a longitudinal clamping driver 343, a longitudinal clamping screw rod 344 and a longitudinal clamping screw block 345. The longitudinal clamping rail 341 is fixed to the top frame 12 and installed along the arrangement direction of the platform frame 21, so that the arrangement direction of the longitudinal clamping rail 341 is the length direction of the door leaf plate, thereby providing conditions for the subsequent clamping and sawing of door leaf plates of different lengths. In addition, the longitudinal clamping slide 342 is slidably disposed on the longitudinal clamping slide rail 341 , and the hanger 331 of the movable clamping assembly 34 is fixedly installed on the longitudinal clamping slide 342 , so that the hanger 331 of the movable clamping assembly 34 can move with the longitudinal clamping slide 342 . In addition, the longitudinal clamping driver 343 is fixed on the top frame 12, and the longitudinal clamping screw 344 is arranged parallel to the longitudinal clamping slide rail 341, and one end of the longitudinal clamping screw 344 is dynamically connected to the longitudinal clamping driver 343. At the same time, the longitudinal clamping screw 345 is threadedly sleeved on the longitudinal clamping screw 344, and the longitudinal clamping screw 345 is also fixed on the hanger 331 of the movable clamping assembly 34, so that when the longitudinal clamping driver 343 is actuated, it can drive the longitudinal clamping screw 344 to rotate, thereby driving the longitudinal clamping screw 345 to move axially along the longitudinal clamping screw 344, that is, the hanger 331 is driven to move on the longitudinal clamping track through the longitudinal clamping screw 345, thereby realizing the movement of the movable clamping assembly 34 relative to the fixed clamping assembly 33, realizing the adjustment of the distance between the movable clamping assembly 34 and the fixed clamping assembly 33, and meeting the clamping requirements of door leaves of different lengths.

[0039] More specifically, the compression adjustment driving assembly 334 for driving the two compression adjustment slide plates 333 to move on the compression adjustment track 332 includes a compression adjustment synchronous belt 3341, two compression adjustment synchronous wheels 3342, and a compression adjustment driver 3343. At this time, the two compression adjustment synchronous wheels 3342 are respectively arranged at both ends of the hanger 331, and the compression adjustment synchronous belt 3341 is wound around the two compression adjustment synchronous wheels 3342. The compression adjustment driver 3343 is installed on the corresponding hanger 331 and is connected to a compression adjustment synchronous wheel 3342 by power, so that the compression adjustment driver 3343 can provide driving force for the rotation of the compression adjustment synchronous belt 3341. In addition, the two strands of the clamping adjustment synchronous belt 3341 are respectively connected to the corresponding two clamping adjustment slides 333. Since the two strands of the clamping adjustment synchronous belt 3341 move in opposite directions and synchronously when rotating, the two clamping adjustment slides 333 can make synchronous opposite movements, that is, the two clamping adjustment slides 333 can move closer to or farther away from each other, and the centering operation of the two clamping adjustment slides 333 is realized, which adapts to the centering adjustment of the two platform frames 21 and has a more reasonable structural design.

[0040] More specifically, the sawing parts 42 at both ends are respectively arranged on the hangers 331 of the fixed clamping assembly 33 and the movable clamping assembly 34, so that the distance between the sawing parts 42 at both ends can also be adjusted, so as to meet the sawing requirements of door panels of different lengths. At this time, each end sawing part 42 includes an end sawing track 421, an end sawing slide 422, an end sawing driver 423, an end sawing screw rod 424, an end sawing screw block 425, an end sawing lifting rail 426, an end sawing lifting frame 427, an end sawing telescopic driver 428 and an end sawing head 429. During installation, the end sawing track 421 is installed on the corresponding hanger 331 and perpendicular to the arrangement direction of the platform frame 21, so that the arrangement direction of the end sawing track 421 is the width direction of the door panel, which provides conditions for the subsequent end sawing part 42 to saw the end of the door panel. In addition, the end sawing slide 422 is slidably arranged on the end sawing track 421. At the same time, the end sawing driver 423 is fixed on the corresponding hanger 331, and the end sawing wire rod 424 is arranged parallel to the end sawing track 421. In addition, one end of the end sawing wire rod 424 is power-connected to the end sawing driver 423, so that the end sawing driver 423 can drive the end sawing wire rod 424 to rotate. In addition, the end sawing screw block 425 is threadedly sleeved on the end sawing wire rod 424, so that when the end sawing driver 423 is actuated, the end sawing screw block 425 can move along the axial direction of the end sawing wire rod 424. At the same time, the end sawing screw block 425 is fixedly installed on the end sawing slide 422, so that the end sawing screw block 425 can drive the end sawing slide 422 to move on the end sawing track 421. In addition, the end sawing lifting rail 426 is installed on the end sawing slide 422 in the vertical direction, and the end sawing lifting frame 427 is slidably installed on the end sawing lifting rail 426, so that the end sawing lifting frame 427 can be vertically lifted under the guidance of the end sawing lifting rail 426. In addition, the end sawing telescopic driver 428 is installed on the end sawing slide 422 in the vertical direction, and the telescopic shaft of the end sawing telescopic driver 428 is connected to the end sawing lifting frame 427 in power, that is, the end sawing telescopic driver 428 provides driving force for the lifting movement of the end sawing lifting frame 427. In addition, the end sawing head 429 is installed on the end sawing lifting frame 427, so that the end sawing head 429 can be lifted and lowered in the vertical direction under the action of the end sawing lifting frame 427, meeting the processing requirements of the saw blade of the end sawing head 429 contacting or away from the door leaf plate.
