Description

Technical Field

[0001] The invention relates to the technical field of wooden door processing, in particular to a multi-angle punching device for wooden door processing. Background Art

[0002] Solid wood doors refer to doors made of natural logs or solid wood composite materials from forests. Most of the wood used is precious wood, such as cherry, walnut, teak, etc. The finished doors have the characteristics of no deformation, corrosion resistance, no cracks, and heat insulation. They are scientifically processed through drying, cutting, planing, mortising, drilling, high-speed milling, assembly, grinding, painting, etc. During the processing of wooden doors, many bolt holes need to be opened on the door panels, such as bolt holes for door handle installation, bolt holes for door lock installation, etc. In addition, cat's eye holes usually need to be drilled on the door for the installation of cat's eyes.

[0003] Since multiple different holes need to be drilled on the same solid wooden door, after the drilling is completed, when the drill is retracted, the tool will use the friction between it and the hole to lift the wooden door, causing the wooden door to shift in position, which will interfere with the position accuracy of drilling the next hole, resulting in a change in the relative distance between the two holes, affecting the later installation of door locks, door handles or cat's eyes and other door appliances.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Summary of the invention

[0024] (III) Beneficial effects

[0025] Compared with the prior art, the present invention provides a multi-angle punching device for wooden door processing, which has the following beneficial effects:

[0026] 1. The present invention adjusts the drill cutter on the Z axis to keep the distance from the drill cutter to the wooden door constant, thereby adapting to the drilling processing requirements of wooden doors of different thicknesses, and in the process of the drill cutter moving downward, the drill cutter drives the pressing ring to move a fixed distance, thereby forming a fixed pressure on the wooden door, thereby preventing the pressing force from gradually increasing as the drill cutter moves downward, causing excessive pressing on the surface of the wooden door and causing indentations in traditional pressing means, and after the wooden door is pressed with a fixed force, as the drill cutter moves downward, the locking body of the pressing ring is replaced, the pressing drive member is lowered with the drill cutter, and the locking assembly continues to limit the position of the pressing ring, thereby forming a stable pressing force on the wooden door during the drilling process of the drill cutter, and during the drilling process, the high-frequency vibration of the drill cutter causes fluctuations in the pressing effect of the pressing ring, resulting in deviations in the verticality of the hole formed by the drilling.

[0027] 2. The present invention utilizes the squeezing force of the pressing ring on the wooden door when the drill starts to retract, so that the squeezing force of the pressing ring on the wooden door overcomes the friction between the drill and the wooden door, thereby preventing the wooden door from being lifted up when the drill is retracted, causing the position shift of the wooden door, causing interference with the position accuracy of drilling the next hole, resulting in a change in the relative distance between the two holes, affecting the later installation of door locks, door handles or cat's eyes and other door appliances.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a multi-angle punching device for wooden door processing.

[0036] See also Figure 1-Figure 5 A multi-angle punching device for processing wooden doors, comprising a processing table 1, on which a drill part that can move along the X-axis, Y-axis and Z-axis directions is installed, the drill part comprises a drill 2, a pressing ring 3, an angle adjustment member 4, a pressing drive member 5 and a locking assembly 6, the drill 2, the pressing ring 3, the pressing drive member 5 and the locking assembly 6 are all installed on the angle adjustment member 4, and the drill 2 is coaxially arranged with the pressing ring 3, the pressing drive member 5 moves synchronously with the drill 2 along the Z-axis, and the pressing ring 3 and the locking assembly 6 can move relatively along the Z-axis direction;

[0037] The drill 2 approaches the wooden door along the Z axis to drive the pressing ring 3 to descend synchronously through the pressing driving member 5 to form elastic extrusion with the wooden door, and then as the drill 2 and the pressing driving member 5 continue to approach the wooden door, the pressing driving member 5 gradually contracts to disengage from the pressing ring 3, and the locking assembly 6 gradually translates along the X axis to complete the locking of the pressing ring 3, and then the pressing driving member 5 descends with the drill 2 to allow the drill 2 to drill a hole in the wooden door;

[0038] After the drill 2 is retracted away from the wooden door along the Z axis, the drill 2 continues to move away from the wooden door along the Z axis to drive the pressing drive 5 to release and engage with the pressing ring 3, and simultaneously squeeze the locking assembly 6 to release the locking of the pressing ring 3. Then the drill 2 synchronously drives the pressing ring 3 to reset through the pressing drive 5 to release the squeezing of the wooden door.

[0039] The elastic extrusion described in this article means that the pressing ring 3 generates elastic force acting on the wooden door, thereby forming an extrusion force on the wooden door.

[0040] In addition, it should be noted that before the drill bit 2 is lowered (i.e., in the initial state of the drill bit), the distance between the lower surface of the pressing ring 3 and the upper surface of the processing table 1 is smaller than the distance between the bottom end of the drill bit 2 and the upper surface of the processing table 1, and the distance difference between the two is greater than the distance required for the pressing ring 3 to move to be locked by the locking assembly 6;

[0041] After placing the wooden door on the processing table 1, the drill bit is moved on the X-axis, Y-axis and Z-axis according to the position of the hole to be drilled, so that the drill bit is translated to the drilling position. Since the drill bit 2 and the pressing drive member 5 maintain synchronous movement on the Z-axis, when the drill bit 2 descends, the drill bit 2 and the pressing drive member 5 synchronously descend along the Z-axis direction, and before the pressing ring 3 is locked by the locking component 6, the pressing drive member 5 is engaged with the pressing ring 3, so that the drill bit 2 synchronously drives the pressing ring 3 to move downward through the pressing drive member 5. When the pressing ring 3 contacts the wooden door, the drill bit 2 continues to press down, so that the pressing ring 3 forms an elastic force, thereby squeezing the wooden door. When the squeezing force of the pressing ring 3 on the wooden door reaches the set value, it means that the position of the pressing ring 3 is locked by the locking component 6. The pressing ring 3 is restricted and cannot move further downward. At this time, when the drill 2 synchronously drives the pressing driving member 5 to continue to descend along the Z axis, since the pressing ring 3 is limited by the position of the locking component 6, the pressing driving member 5 is resisted by the pressing ring 3 when it continues to descend, so that the pressing driving member 5 contracts along the X axis until the end of the pressing driving member 5 that is engaged with the pressing ring 3 is separated from the pressing ring 3 and fits with the side of the pressing ring 3. In this process, since the pressing driving member 5 gradually separates from the pressing ring 3, space is provided for the release of the locking component 6. As the pressing driving member 5 gradually contracts, the locking component 6 is gradually released, thereby replacing the pressing driving member 5 to limit the position of the pressing ring 3, thereby avoiding the release of the elastic force of the pressing ring 3, so that the pressing ring 3 always exerts pressure on the wooden door.

[0042] When the pressing drive 5 disengages from the pressing ring 3, the drill 2 starts to rotate around its central axis while keeping descending to drill the drilling position; after the drilling is completed, the drill 2 starts to retract. At this time, since the pressing ring 3 has a squeezing force on the wooden door, when the drill 2 is retracted, the squeezing force of the pressing ring 3 on the wooden door overcomes the friction between the drill 2 and the wooden door, thereby preventing the wooden door from being lifted up when the drill 2 is retracted. Subsequently, when the pressing drive 5 moves up with the drill 2 and is reset to the position where the pressing ring 3 is locked, the pressing drive 5 is gradually released to squeeze the locking assembly 6, so that the pressing drive 5 is re-engaged with the pressing ring 3, and the locking assembly 6 is squeezed out of the movement space of the pressing ring 3. Subsequently, the drill 2 continues to reset, and the pressing ring 3 is lifted by the pressing drive 5 to release the pressing on the wooden door.

[0043] The present invention adjusts the drill cutter part on the Z axis to keep the distance between the drill cutter part and the wooden door always constant, so as to adapt to the drilling processing requirements of wooden doors of different thicknesses, and cooperates with the drill cutter 2 to drive the pressing ring 3 to move a fixed distance during the downward movement, so as to form a fixed pressure on the wooden door, thereby preventing the pressing force from gradually increasing as the drill cutter 2 moves downward, and excessive pressing on the surface of the wooden door to cause indentations in traditional pressing means, and after the wooden door is pressed with a fixed force, as the drill cutter 2 moves downward, the locking body of the pressing ring 3 is replaced, so that the pressing driving part 5 descends with the drill cutter 2, and the locking assembly 6 continues to limit the position of the pressing ring 3, so that during the drilling process of the drill cutter 2, a stable pressing force is formed on the wooden door, and during the drilling process, due to the high-frequency vibration of the drill cutter 2, the pressing effect of the pressing ring 3 fluctuates, causing the verticality of the hole formed by the drilling to deviate;

[0044] In addition, when the drill bit 2 starts to retract, the pressing force of the pressing ring 3 on the wooden door is used to overcome the friction between the drill bit 2 and the wooden door, thereby preventing the wooden door from being lifted up when the drill bit 2 is retracted, causing the wooden door to shift in position, causing interference with the position accuracy of drilling the next hole, resulting in a change in the relative distance between the two holes, affecting the later installation of door locks, door handles or cat's eyes and other door appliances.

[0045] Furthermore, for the above-mentioned pressing ring 3, a plurality of pressure measuring points 7 are provided on the lower surface of the pressing ring 3, and the pressure measuring points 7 are distributed along the circumference of the lower surface of the pressing ring 3. When the pressing ring 3 is lowered along the Z axis to form elastic extrusion with the wooden door, the angle adjustment member 4 is controlled to operate according to the pressure value of each pressure measuring point 7 to adjust the angle between the central axis of the pressing ring 3 and the surface of the wooden door where the hole is drilled;

[0046] When the pressing ring 3 contacts the wooden door, when the pressing ring 3 initially forms elastic force (that is, after the deformation of the pressing ring 3 reaches the set threshold), the drill 2 stops descending. At this time, whether the wooden door is placed horizontally is judged based on whether the pressures received by each pressure measuring point 7 are uniform. If the pressures detected by each pressure measuring point 7 are uneven (that is, the error is not within the set safety range), it means that the wooden door is not placed horizontally, otherwise it is placed horizontally.

[0047] If the wooden door is not placed horizontally, there will be an angle difference between the drill bit 2 and the cutting position of the wooden door, and the drilled hole will also be inclined (that is, the verticality of the hole will deviate), which will seriously interfere with the later installation of door locks, door handles or cat eyes and other door appliances. At this time, the inclination is obtained according to the pressure value of each pressure measuring point 7, and the angle adjusting member 4 is adjusted according to the inclination to keep the drill bit and the wooden door vertical.

[0048] It should be noted that the pressure measuring point 7 includes a rubber sleeve, a pressure sensor, a force measuring spring and a force measuring seat. The force measuring seat is installed on the lower surface of the pressing ring 3 and can only move away from or close to the pressing ring 3 along the Z-axis direction. The pressure sensor is fixed on the lower surface of the pressing ring 3. The two ends of the force measuring spring are respectively fixed on the force measuring seat and the pressing ring 3. According to the elastic force of each pressure measuring point 7, the deformation of the force measuring spring at this point is obtained, and the height of each point from the surface of the wooden door is obtained according to the deformation of multiple force measuring springs. According to the position information of multiple height points in three-dimensional space, the inclination of the wooden door relative to the pressing ring 3 is calculated using trigonometric functions, thereby adjusting the angle adjustment member 4.

[0049] Further, for the above-mentioned angle adjustment member 4, the angle adjustment member 4 includes a U-shaped plate 401, a mounting plate 402 and a mounting seat 403, a driving shaft is opened on one side of the U-shaped plate 401, the driving shaft is rotatably mounted on the mounting seat 403, a turbine 404 is fixedly mounted on one end of the driving shaft, the turbine 404 is meshed with a worm rod 405, the worm rod 405 is rotatably mounted on the mounting seat 403, and one end of the worm rod 405 is fixedly mounted on the output shaft of the first motor 406;

[0050] The mounting plate 402 is rotatably mounted on the inner side of the U-shaped plate 401, and a second turbine 407 is fixedly mounted on its rotating shaft penetrating the U-shaped plate 401, and a second worm 408 is meshed with the second turbine 407, and the second worm 408 is rotatably mounted on the outer side of the U-shaped plate 401, and one end of the second worm 408 is fixedly mounted on the output shaft of the second motor 409;

[0051] The worm 405 is driven to rotate by the first motor 406, and the worm 405 is used to drive the turbine 404 to rotate, thereby driving the U-shaped plate 401 to rotate, thereby achieving the angle adjustment of the mounting plate 402 in the X-axis direction. Similarly, the second motor 409, the second turbine 407 and the second worm 408 cooperate to achieve the angle adjustment of the mounting plate 402 in the Y-axis direction.

[0052] In addition, it should be noted that the cooperation between the second turbine 407 and the second worm 408 and the worm 405 and the turbine 404 is mainly for the stability of the angle adjustment, so that the angle adjustment is active adjustment rather than passive adjustment.

[0053] When the present invention utilizes the pressing ring 3 to elastically extrude and fix the wooden door, the stress condition of the pressure measuring point 7 at the bottom of the pressing ring 3 is used to calculate whether the wooden door is in a horizontal state, and according to the state of the wooden door, the vortex rod 405 is driven to rotate by the first motor 406, and the turbine 404 is driven to rotate by the vortex rod 405, thereby driving the U-shaped plate 401 to rotate, thereby achieving the angle adjustment of the mounting plate 402 in the X-axis direction. Similarly, the cooperation of the second motor 409, the second turbine 407 and the second vortex rod 408 is used to achieve the angle adjustment of the mounting plate 402 in the Y-axis direction, thereby achieving the angle adjustment of the drill part composed of the pressing ring 3, the drill 2, etc. relative to the wooden door, thereby avoiding a large error in the verticality of the drilled hole, which affects the installation of door locks, door handles or cat's eyes and other door appliances in the later stage.

[0054] Further, for the above-mentioned mounting plate 402, a slide rail 8 is provided on the mounting plate 402, a cylinder 9 is fixedly installed on the mounting plate 402, an integrated block 10 is fixedly installed on the output shaft of the cylinder 9, the integrated block 10 is slidably installed with the slide rail 8, and a stepper motor 11 is fixedly installed on the integrated block 10, a tool holder 12 is fixedly installed on the rotating shaft of the stepper motor 11, and a drill 2 is threadedly connected to the tool holder 12;

[0055] The cylinder 9 is used to provide the required descending driving force for the drill 2 to move downward for drilling. The output of the cylinder 9 drives the integrated block 10 to move downward along the slide rail 8. Since the stepper motor 11 is fixedly installed on the integrated block 10, the tool seat 12 is connected to the drill 2, and the tool seat 12 is fixed on the rotating shaft of the stepper motor 11, when the cylinder 9 drives the integrated block 10 to move downward, the drill 2 is synchronously driven to descend, and the stepper motor 11 provides torque for the rotation of the tool.

[0056] Further, for the above-mentioned locking assembly 6, the locking assembly 6 includes an L-shaped locking seat 601, the L-shaped locking seat 601 is fixedly mounted on the mounting plate 402, one end of the upper surface of the L-shaped locking seat 601 is provided with a limiting groove 602, and a through groove is provided in the limiting groove 602 for sliding connection with the pressing ring 3;

[0057] A sleeve 607 is fixedly mounted on the upper surface of the L-shaped locking seat 601, and a first spring seat 603 is slidably connected to the inner wall of the sleeve 607. A locking rod 604 is fixedly mounted on one side of the first spring seat 603. The locking rod 604 is slidably connected relative to the sleeve 607, and a locking block 605 is fixedly mounted on one end of the locking rod 604.

[0058] The locking rod 604 is coaxially provided with a locking spring 606, and both ends of the locking spring 606 are fixedly mounted on the first spring seat 603 and the sleeve 607 respectively;

[0059] Before the pressing ring 3 is locked, the locking spring 606 is in a compressed state, and the locking block 605 is in contact with the side of the pressing ring 3. As the pressing ring 3 gradually moves downward under the action of the pressing drive 5, when the pressing ring 3 moves down to the set position, the pressing ring 3 is in contact with the limiting groove 602. At this time, the locking block 605 corresponds to the pressing drive 5, and the pressing drive 5 limits the movement of the locking block 605 under the elastic force of the locking spring 606. As the pressing drive 5 continues to move downward, the pressing drive 5 is subjected to the resistance of the pressing ring 3, thereby moving along the X-axis to gradually disengage from the pressing ring 3. Therefore, the locking block 605 is under the elastic force of the locking spring 606, and is transmitted by the locking rod 604 and the first spring seat 603. As the pressing drive 5 moves and contracts along the X-axis, it is gradually released, so that the locking block 605 enters the activity space of the pressing ring 3, and the pressing ring 3 is reset under the action of the elastic force, ensuring stable pressure on the wooden door during the drilling process and avoiding position displacement during the drilling process of the wooden door.

[0060] Further, for the above-mentioned pressing ring 3, the pressing ring 3 includes a base ring 301, the base ring 301 is coaxially arranged with the drill 2, a connecting frame 302 is fixedly installed on one side of the base ring 301, a guide rod 303 is fixedly installed on the upper surface of the connecting frame 302, a second spring seat 304 is fixedly installed on one end of the guide rod 303, the second spring seat 304 is slidably connected to the inner wall of the main drive column 305, and a pressing spring 306 is coaxially arranged on the guide rod 303, and the two ends of the pressing spring 306 are respectively fixedly installed on the second spring seat 304 and the inner wall of the main drive column 305;

[0061] The main drive column 305 is slidably connected to the through groove in the limiting groove 602, and a locking groove 307 is formed at the end of the main drive column 305, and the locking groove 307 is engaged with the pressing driving member 5;

[0062] When the pressing drive member 5 is in the initial state, the pressing drive member 5 is engaged with the locking groove 307. When the pressing drive member 5 is lowered along with the drill bit 2, the pressing drive member 5 drives the main driving column 305 to descend by engaging with the locking groove 307, thereby driving the base ring 301 connected to the main driving column 305 to descend. When the base ring 301 contacts the wooden door, as the pressing drive member 5 continues to move downward, the main driving column 305 gradually approaches the base ring 301. Since the base ring 301 does not change its position on the Z axis after contacting the wooden door, as the main driving column 305 descends, a relative displacement occurs between the main driving column 305 and the guide rod 303, thereby causing the pressing spring 306 to deform and generate a pulling force, thereby causing the guide rod 303 to generate a downward force under the action of the pulling force, so that the guide rod 303 applies a downward extrusion force to the base ring 301 through the connecting frame 302, that is, the base ring 301 applies an extrusion force to the wooden door.

[0063] When the pressing drive member 5 continues to move downward, the pressing drive member 5 and the side edge of the locking groove 307 are squeezed and offset, so that the pressing drive member 5 gradually disengages from the locking groove 307, and the locking block 605 enters the locking groove 307, limiting the reset of the main drive column 305, thereby maintaining a stable tension of the pressing spring 306, and further stabilizing the pressing force of the base ring 301 on the wooden door.

[0064] Further, for the above-mentioned pressing driving member 5, the pressing driving member 5 includes a traction chamber 501, the traction chamber 501 is opened on the integrated block 10, the inner wall of the traction chamber 501 is slidably connected with a third spring seat 502, a traction rod 503 is fixedly installed on one side of the third spring seat 502, and a wedge block 504 is fixedly installed on one end of the traction rod 503, and the wedge block 504 is clamped with the locking groove 307;

[0065] The traction rod 503 is coaxially provided with a traction spring 505, and the two ends of the traction spring 505 are respectively fixedly mounted on the inner wall of the traction chamber 501 and the third spring seat 502;

[0066] The elastic coefficient of the traction spring 505 is greater than that of the pressing spring 306 and the locking spring 606, that is, when the traction spring 505 is released from the compressed state, it can overcome the elastic force generated by the locking spring 606, so that the locking spring 606 is compressed until the locking block 605 is separated from the activity space of the main drive column 305 (that is, separated from the locking groove 307); similarly, when the wedge block 504 is engaged with the locking groove 307, when the wedge block 504 moves downward to compress the pressing spring 306, the resistance generated by the pressing spring 306 to the downward movement of the wedge block 504 cannot cause the wedge block 504 to move along the X-axis to compress the traction spring 505.

[0067] Since the traction bin 501 is provided on the integrated block 10, when the integrated block 10 moves downward, the wedge block 504 drives the main drive column 305 to move downward by engaging with the locking groove 307. When the main drive column 305 is limited by the position of the limit groove 602, it no longer moves downward, and when the wedge block 504 continues to descend, the inclined surface of the wedge block 504 is subjected to the rigid resistance of the locking groove 307 and moves to both sides, thereby squeezing the traction spring 505 through the traction rod 503 and the third spring seat 502, so that the traction spring 505 is compressed, thereby realizing the contraction of the wedge block 504. When the side surface of the wedge block 504 is in contact with the side surface of the main drive column 305, the wedge block 504 remains in the contracted state and moves downward, and then the drill 2 performs normal drilling.

[0068] Further, for the above-mentioned processing table 1, the processing table 1 is provided with a gantry 13 slidably arranged along the Y-axis direction, the gantry 13 is provided with a carrier plate 14 slidably arranged along the X-axis direction, the carrier plate 14 is provided with a mounting base 15 slidably arranged along the Z-axis direction, and the mounting base 15 is fixedly installed with the mounting seat 403;

[0069] The above-mentioned installation structure is a lifting and translation mechanism on a traditional machine tool, which mainly drives the lead screw to rotate through a motor, thereby realizing the translation of the sliding body (carrier plate 14 and installation base 15) connected to the lead screw.

[0070] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
