DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

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

[0036] Please refer to Figures 1-5 A multi-angle punching device for wooden door processing, comprising a processing table 1, wherein a drill part movable along X-axis, Y-axis and Z-axis directions is installed on the processing table 1, the drill part comprises a drill 2, a pressing ring 3, an angle adjusting part 4, a pressing driving part 5 and a locking assembly 6, the drill 2, the pressing ring 3, the pressing driving part 5 and the locking assembly 6 are all installed on the angle adjusting part 4, the drill 2 and the pressing ring 3 are coaxially arranged, the pressing driving part 5 moves synchronously with the drill 2 along Z-axis, and the pressing ring 3 and the locking assembly 6 are relatively movable along Z-axis direction;

[0037] The drill 2 approaches the wooden door along Z-axis to drive the pressing ring 3 to synchronously descend to form elastic extrusion with the wooden door through the pressing driving part 5, then the pressing driving part 5 gradually shrinks to separate from the pressing ring 3 along with the continuous approach of the drill 2 and the pressing driving part 5 to the wooden door, and the locking assembly 6 gradually translates along X-axis to complete the locking of the pressing ring 3, then the drill 2 performs drilling on the wooden door along with the descent of the pressing driving part 5;

[0038] After the drill bit 2 retreats along the Z axis away from the wooden door, the drill bit 2 continues to retreat along the Z axis to drive the pressing driving part 5 to release the clamping with the pressing ring 3, and synchronously extrude the locking assembly 6 to release the locking of the pressing ring 3, and then the drill bit 2 synchronously drives the pressing ring 3 to reset through the pressing driving part 5 to release the extrusion of the wooden door.

[0039] The elastic extrusion described herein is that the pressing ring 3 exerts an elastic force on the wooden door to form an extrusion force on the wooden door.

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

[0041] After the wooden door is placed on the processing table 1, the drill bit part is moved on the X axis, Y axis and Z axis according to the position of the hole to be drilled to translate the drill bit part to the hole position. Since the drill bit 2 and the pressing driving part 5 keep synchronous movement on the Z axis, when the drill bit 2 is lowered, the drill bit 2 and the pressing driving part 5 synchronously descend along the Z axis direction, and before the pressing ring 3 is locked by the locking assembly 6, the pressing driving part 5 is clamped with the pressing ring 3, so that the drill bit 2 also realizes synchronous driving of the pressing ring 3 downwardly moving through the pressing driving part 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 to extrude the wooden door. When the extrusion force of the pressing ring 3 on the wooden door reaches a set value, it means that the position of the pressing ring 3 is limited by the locking assembly 6 and cannot continue to move downwardly. At this time, when the drill bit 2 synchronously drives the pressing driving part 5 to continue to descend along the Z axis, the pressing driving part 5 continues to descend and is resisted by the pressing ring 3, so that the pressing driving part 5 shrinks along the X axis direction until the end of the pressing driving part 5 clamped with the pressing ring 3 is separated from the pressing ring 3 and is attached to the side surface of the pressing ring 3. In this process, since the pressing driving part 5 gradually separates from the pressing ring 3, it provides space for the release of the locking assembly 6. With the gradual shrinking of the pressing driving part 5, the locking assembly 6 is gradually released to replace the pressing driving part 5 to limit the position of the pressing ring 3, thereby avoiding the release of the elastic force of the pressing ring 3 to make the pressing ring 3 always form a pressure on the wooden door.

[0042] When the pressing driving part 5 is separated from the pressing ring 3, the drill bit 2 starts to rotate around the central axis thereof while keeping descending to drill the hole; after the drilling is completed, the drill bit 2 starts to retreat, at this time, due to the extrusion force of the pressing ring 3 on the wooden door, the extrusion force of the pressing ring 3 on the wooden door overcomes the friction between the drill bit 2 and the wooden door, thereby preventing the wooden door from being lifted when the drill bit 2 retreats, and then when the pressing driving part 5 is reset to the position where the pressing ring 3 is locked along with the drill bit 2, the pressing driving part 5 gradually releases the extrusion locking assembly 6 to make the pressing driving part 5 be clamped with the pressing ring 3 again and extrude the locking assembly 6 out of the movement space of the pressing ring 3, and then the drill bit 2 continues to reset and lifts the pressing ring 3 through the pressing driving part 5 to release the pressing on the wooden door.

[0043] The present application adjusts the drill bit part on the Z axis to keep the distance between the drill bit part and the wooden door constant, thereby adapting to the drilling requirements of wooden doors of different thicknesses, and in cooperation with the drill bit 2 in the descending process, the driving pressing ring 3 moves a fixed distance to form a fixed pressure on the wooden door, thereby preventing the traditional pressing means from gradually increasing the pressing force with the descent of the drill bit 2 to form excessive pressure on the surface of the wooden door and cause indentation, and after forming a fixed pressure on the wooden door, the locking body of the pressing ring 3 is replaced with the descent of the drill bit 2, the drill bit 2 descends, and the locking assembly 6 continues to limit the position of the pressing ring 3, thereby forming a stable pressing force on the wooden door during the drilling of the drill bit 2, preventing the verticality of the hole formed by drilling from deviating due to the high-frequency vibration of the drill bit 2 during the drilling process, causing the pressing effect of the pressing ring 3 to fluctuate.

[0044] In addition, the retreat of the drill bit 2 utilizes the extrusion force of the pressing ring 3 on the wooden door to make the extrusion force of the pressing ring 3 on the wooden door overcome the friction between the drill bit 2 and the wooden door, thereby preventing the wooden door from being lifted when the drill bit 2 retreats, causing the wooden door to deviate in position, interfering with the position accuracy of the next hole, causing the relative distance between the two holes to change, and affecting the installation of door hardware such as door locks, door handles or cat eyes.

[0045] Further, for the above-mentioned pressing ring 3, a plurality of pressure measuring points 7 are arranged on the lower surface of the pressing ring 3 and are distributed along the circumference of the lower surface of the pressing ring 3, when the pressing ring 3 descends along the Z axis to form elastic extrusion with the wooden door, the angle adjusting part 4 is controlled to operate to adjust the included angle between the central axis of the pressing ring 3 and the surface of the wooden door at the drilling position according to the pressure values of the pressure measuring points 7.

[0046] When the pressing ring 3 is in contact with the wooden door, the drill 2 stops descending when the pressing ring 3 is in the initial stage of forming elasticity (i.e. the deformation amount of the pressing ring 3 reaches a set threshold value), and whether the wooden door is horizontally placed is determined according to whether the pressures received by the pressure measuring points 7 are uniform. If the pressures detected by the pressure measuring points 7 are not uniform (i.e. the error is not within a set safety range), it means that the wooden door is not horizontally placed, otherwise, it means that the wooden door is horizontally placed.

[0047] If the wooden door is not horizontally placed, the drill 2 has an angle difference with the cutting position of the wooden door, and the drilled hole is also inclined (i.e. the perpendicularity of the hole is deviated), which seriously interferes with the installation of the door lock, handle or cat eye and other door accessories. According to the pressure values of the pressure measuring points 7, the inclination is obtained, and the angle adjusting member 4 is adjusted according to the inclination to keep the drill part perpendicular to the wooden door.

[0048] It should be noted that the pressure measuring point 7 includes a rubber sleeve, a pressure sensor, a force spring and a force seat. The force seat is installed on the lower surface of the pressing ring 3 and can only move away from or approach 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 spring are fixedly installed on the force seat and the pressing ring 3, respectively. According to the elastic force of each pressure measuring point 7, the deformation amount of the force spring at the point is obtained. According to the deformation amounts of multiple force springs, the heights of multiple points from the surface of the wooden door are obtained. According to the position information of the multiple height points in the three-dimensional space, the inclination of the wooden door relative to the pressing ring 3 is calculated by using trigonometric functions, so as to adjust the angle adjusting member 4.

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

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

[0051] Thus, the first motor 406 drives the worm 405 to rotate, the worm 405 drives the worm wheel 404 to rotate, and the U-shaped plate 401 is driven to rotate, thereby achieving the angle adjustment of the mounting plate 402 in the X-axis direction.

[0052] In addition, it should be noted that the cooperation of the second worm wheel 407 and the second worm 408 and the cooperation of the worm 405 and the worm wheel 404 are mainly to stabilize the angle adjustment, so that the angle adjustment is active adjustment, not passive adjustment.

[0053] When the wood door is elastically extruded and fixed by the pressing ring 3, the stress state of the pressure measuring point 7 at the bottom of the pressing ring 3 is used to calculate whether the wood door is in a horizontal state, and according to the state of the wood door, the first motor 406 drives the worm 405 to rotate, the worm 405 drives the worm wheel 404 to rotate, and the U-shaped plate 401 is driven to rotate, thereby achieving the angle adjustment of the mounting plate 402 in the X-axis direction, and the cooperation of the second motor 409, the second worm wheel 407 and the second worm 408 achieves the angle adjustment of the mounting plate 402 in the Y-axis direction, thereby achieving the angle adjustment of the drill bit part composed of the pressing ring 3 and the drill bit 2 relative to the wood door, avoiding large errors in the perpendicularity of the drilled hole, and affecting the installation of the door lock, the door handle or the cat eye and other door accessories in the later period.

[0054] Further, for the mounting plate 402, a sliding rail 8 is formed on the mounting plate 402, a gas cylinder 9 is fixedly installed on the mounting plate 402, an integrated block 10 is fixedly installed on the output shaft of the gas cylinder 9, the integrated block 10 is slidingly installed with the sliding rail 8, a stepping motor 11 is fixedly installed on the integrated block 10, a tool seat 12 is fixedly installed on the rotating shaft of the stepping motor 11, and the drill bit 2 is threadedly connected to the tool seat 12.

[0055] The gas cylinder 9 provides the required descending driving force for the drill bit 2 to drill a hole, the output of the gas cylinder 9 drives the integrated block 10 to move downward along the sliding rail 8, since the stepping motor 11 is fixedly installed on the integrated block 10, the tool seat 12 is connected with the drill bit 2, and the tool seat 12 is fixed on the rotating shaft of the stepping motor 11, therefore, when the gas cylinder 9 drives the integrated block 10 to move downward, the drill bit 2 is synchronously driven to descend, and the stepping motor 11 provides torque for the rotation of the tool.

[0056] Further, for the above-mentioned locking assembly 6, the locking assembly 6 comprises an L-shaped locking seat 601 fixedly installed 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 formed in the limiting groove 602 for sliding connection with the pressing ring 3;

[0057] The upper surface of the L-shaped locking seat 601 is fixedly installed with a sleeve 607, the inner wall of the sleeve 607 is slidingly connected with a first spring seat 603, one side of the first spring seat 603 is fixedly installed with a locking rod 604, the locking rod 604 is slidingly connected with the sleeve 607, and one end of the locking rod 604 is fixedly installed with a locking block 605;

[0058] The locking rod 604 is coaxially provided with a locking spring 606, and the two ends of the locking spring 606 are fixedly installed 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, the locking block 605 is in close contact with the side surface of the pressing ring 3, as the pressing ring 3 gradually moves downward under the action of the pressing driving part 5, when the pressing ring 3 moves to a set position, the pressing ring 3 is in close contact with the limiting groove 602, at this time, the locking block 605 corresponds to the pressing driving part 5, the pressing driving part 5 limits the movement of the locking block 605 under the elastic force of the locking spring 606, as the pressing driving part 5 continues to move downward, the pressing driving part 5 is subjected to the resistance of the pressing ring 3, so as to move along the X-axis to gradually separate from the pressing ring 3, therefore, the locking block 605 is gradually released by shrinking along with the movement of the pressing driving part 5 along the X-axis through the transmission of the locking rod 604 and the first spring seat 603, so as to make the locking block 605 enter the active space of the pressing ring 3, and the pressing ring 3 is reset under the action of the elastic force, thereby ensuring stable pressure on the wooden door during the drilling process and avoiding position deviation of the wooden door during the drilling process.

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

[0061] The main driving column 305 is in sliding connection with the through slot in the limiting slot 602, and the end of the main driving column 305 is provided with a locking slot 307, which is in clamping connection with the pressing driving part 5;

[0062] In the initial state, the pressing driving part 5 is in clamping connection with the locking slot 307, when the pressing driving part 5 descends with the drill bit 2, the pressing driving part 5 drives the main driving column 305 to descend through the clamping connection with the locking slot 307, and in turn drives the base ring 301 connected with the main driving column 305 to descend, when the base ring 301 contacts the wooden door, with the continuous downward movement of the pressing driving part 5, the main driving column 305 gradually approaches the base ring 301, since the position of the base ring 301 on the Z-axis no longer changes after contacting the wooden door, with the descent of the main driving column 305, the relative displacement between the main driving column 305 and the guide rod 303 is generated, so that the pressing spring 306 is deformed to generate a pulling force, and in turn the guide rod 303 generates 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 driving part 5 continues to move downward, the pressing driving part 5 is offset by extrusion with the side edge of the locking slot 307, so that the pressing driving part 5 gradually separates from the locking slot 307, and the locking block 605 enters the locking slot 307 to limit the reset of the main driving column 305, so as to maintain the stable pulling force of the pressing spring 306, and in turn to maintain the stable extrusion force of the base ring 301 to the wooden door.

[0064] Further, for the above-mentioned pressing driving part 5, the pressing driving part 5 comprises a traction bin 501, the traction bin 501 is provided on the integrated block 10, the inner wall of the traction bin 501 is in sliding connection with a third spring seat 502, one side of the third spring seat 502 is fixedly installed with a traction rod 503, one end of the traction rod 503 is fixedly installed with a wedge block 504, the wedge block 504 is in clamping connection with the locking slot 307;

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

[0066] The elastic coefficient of the traction spring 505 is greater than that of the compression spring 306 and the locking spring 606, that is, when the traction spring 505 is released from the compressed state, the traction spring 505 can overcome the elastic force generated by the locking spring 606 to compress the locking spring 606 to the locking block 605 to be out of the active space of the main drive column 305 (that is, out of the locking groove 307); similarly, when the wedge block 504 is clamped with the locking groove 307, the wedge block 504 is moved downward to compress the compression spring 306, and the resistance generated by the compression spring 306 to the downward movement of the wedge block 504 cannot promote the wedge block 504 to move along the X-axis to compress the traction spring 505.

[0067] Since the traction bin 501 is opened 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 clamping with the locking groove 307, and when the main drive column 305 is limited in position by the limiting groove 602, it can no longer move downward, and when the wedge block 504 continues to drop, the inclined surface of the wedge block 504 is resisted by the rigidity of the locking groove 307, and moves to both sides, thereby pressing 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 attached to the side surface of the main drive column 305, the wedge block 504 keeps the contraction state and moves downward, and then the drill bit 2 performs normal drilling.

[0068] Further, for the machining table 1, the machining table 1 is slidably arranged along the Y-axis direction, the gantry 13 is slidably arranged along the X-axis direction, the carrier plate 14 is slidably arranged along the Z-axis direction, and the mounting base 15 is fixedly installed on the mounting base 15.

[0069] The mounting structure is a lifting and translating mechanism on a conventional machine tool, which mainly realizes the translation of the sliding body (carrier plate 14 and mounting base 15) connected with the lead screw by driving the lead screw to rotate by the motor.

[0070] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
