Description

Technical Field

[0001] This invention belongs to the field of wood processing and surface treatment technology, and particularly relates to a grinding device and a grinding process for wood carvings. Background Technology

[0002] Wood carvings are highly sought after in the market due to their unique artistic value. Their processing usually includes rough carving, fine carving, and polishing. Among these processes, polishing is the key step that determines the smoothness and texture of the finished product.

[0003] Wood grinding generates a large amount of fine wood dust. If it cannot be removed in time, it will not only obstruct the view during processing and affect the heat dissipation of the equipment, but also seriously endanger the respiratory health of the operators. It also has poor adaptability to irregular surfaces: the dust suction port of existing automated grinding equipment is usually fixed next to the grinding spindle. Since the surface of wood carvings is mostly relief, hollow or irregular curved, when the grinding robot arm moves along the curved surface, the fixed dust suction port cannot adjust its height with the surface undulation. When the distance is too far, it is easy to cause the negative pressure suction to weaken, resulting in poor dust removal effect. When the distance is too close, it is easy to have a rigid collision with the wood carving workpiece, damaging the workpiece or equipment. When grinding the sides or dead corners of wood carvings, it is often necessary to adjust the angle of the dust suction hood to obtain the best dust suction flow field. However, existing devices often require stopping the machine and manually disassembling and adjusting with bolts, which is inefficient and the positioning accuracy is difficult to guarantee. There is room for improvement. Summary of the Invention

[0004] The purpose of this invention is to provide a grinding device and a sanding process for wood carvings in order to solve the problem that fixed dust inlets cannot adjust their height according to surface undulations.

[0022] The second spring is sleeved on the outside of the guide rod, and its two ends are respectively connected to the end of the guide rod and one side of the sliding seat;

[0023] A limiting screw is provided, with one end of the limiting screw rotatably connected to a limiting sleeve via a rotating shaft and a bearing. The limiting sleeve fits against one side of the sliding seat. The limiting screw is externally threaded to a screw seat, which is embedded on the other side of the stabilizer.

[0024] As a further description of the above technical solution:

[0025] The stabilizing mechanism also includes:

[0026] The third spring is sleeved on the outside of the lifting rod. The two ends of the third spring are connected to the sliding seat and one side of the follower plate, respectively, and the axial impact is absorbed by the third spring.

[0027] As a further description of the above technical solution:

[0028] The stabilizing mechanism also includes:

[0029] Follower rods, multiple follower rods are arranged around the axis of the follower disk, and a rotating block is connected to the top of the follower rod. The rotating block is rotatably connected to the groove opened on the periphery of the follower disk through a shaft.

[0030] A limiting groove is formed on the top of the follower disk, and a limiting bolt is threaded into the limiting groove. The limiting bolt is connected to the outside of the shaft to limit the rotation of the shaft.

[0031] As a further description of the above technical solution:

[0032] Also includes:

[0033] An insertion platform is connected to the top of the processing platform. The top of the insertion platform is arrayed with multiple sets of assembly holes, and clamping units are provided in the assembly holes.

[0034] As a further description of the above technical solution:

[0035] The dust extraction and ventilation mechanism includes:

[0036] The blower hood has a sealing plate inside, and the sealing plate has multiple sealing slots around its axis. The blower hood is connected to an external negative pressure suction device through a pipe.

[0037] As a further description of the above technical solution:

[0038] The aforementioned dust extraction and ventilation system also includes:

[0039] The adjusting ring has multiple shielding plates connected around its inner cavity along the axis. The closing stroke of the shielding plates and the sealing groove is controlled by rotating the adjusting ring.

[0040] A limiting ring is connected to the front side of the blower hood. Multiple limiting blocks are connected around the inner circumference of the limiting ring, and multiple protrusions are connected around the outer circumference of the adjusting ring. The relative angle between the protrusions and the limiting blocks is limited by the contact angle between them and the shielding plate.

[0041] As a further description of the above technical solution:

[0042] A wood carving polishing process includes the following steps:

[0043] S1. Workpiece clamping and positioning: Place the wood carving component to be processed on the insertion platform at the top of the processing platform. Select the corresponding clamping unit position according to the size of the wood carving component. The operator manually pushes the handle of the clamping unit to the vertical position. The pressure arm is driven down through the linkage mechanism. When the hinge point crosses the center dead point, self-locking is achieved, and the wood carving component is stably fixed on the insertion platform, completing the preparation before processing.

[0044] S2. Pre-adjustment of the dust removal mechanism angle: Based on the sanding area and texture direction of the wood carving components, pre-adjust the circumferential heat dissipation and dust suction angle of the exhaust dust removal mechanism. Pull down the stabilizer to overcome the tension of the first spring, so that the first limiting tooth plate connected to the bottom of the stabilizer is separated from the second limiting tooth plate connected to the top of the control seat, and the engagement lock is released. Rotate the stabilizer to the preset angle so that the exhaust dust removal mechanism faces the best chip removal direction. Release the stabilizer. Under the rebound action of the first spring, the first limiting tooth plate and the second limiting tooth plate re-engage, and the angle lock is completed. The limiting screw can be rotated as needed to adjust the initial position of the front side of the sliding seat in the screw seat to prevent the sliding seat from deflecting unexpectedly.

[0045] S3. Negative pressure suction flow adjustment: Adjust the suction intensity according to the coarseness of the wood carving and sanding process. Start the external negative pressure suction equipment, rotate the adjustment ring on the exhaust and dust removal mechanism, and the adjustment ring drives the internal shielding plate to rotate along the axis, changing the shielding area of ​​the shielding plate on the sealed groove on the inner sealing plate of the blower hood, adjusting the effective cross section of the air inlet. The current opening size is locked by the cooperation of the protrusion on the adjustment ring and the limit block on the limit ring, preventing the suction from being too strong and affecting the grinding accuracy or the suction from being too weak and causing poor chip removal.

[0046] S4. Adaptive follow-up grinding: The moving module and drive robotic arm are activated to control the grinding head to run according to the preset command trajectory to grind the wood carving components. When the grinding head approaches the wood carving surface, the following rods arranged around the follower plate will first contact the non-machined surface or reference surface of the wood carving component. As the grinding head moves along the curved surface of the wood carving, the following rods are subjected to the reaction force of the workpiece surface, driving the follower plate and the lifting rod to slide upward in the sliding seat. The lifting rod drives the top exhaust dust removal mechanism to adjust the axial height synchronously, always keeping the relative distance between the dust suction port and the grinding point constant, ensuring that the waste is drawn into the blower hood as soon as possible. The third spring absorbs the impact force when the follower plate moves up and down, making the lifting action smooth. When horizontal vibration or displacement occurs during the grinding process, the sliding seat slides along the guide rod in the stroke groove and compresses or stretches the second spring, using the elasticity to maintain the lateral stability of the exhaust dust removal mechanism and avoid rigid collisions.

[0047] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0048] 1. In this invention, by setting up a linkage mechanism consisting of a follower plate, a follower rod, and a lifting rod, the device can mechanically sense the undulations of the wood carving surface. When the follower plate contacts the wood surface, it automatically drives the top dust extraction mechanism to perform axial extension and retraction adjustment, always maintaining the optimal dust extraction distance, ensuring that wood chips are fully extracted and removed, while effectively avoiding hard collisions between the dust extraction mechanism and the wood carving workpiece.

[0049] 2. In this invention, by utilizing the meshing of the end face teeth of the first and second limiting gears, and in conjunction with the elastic reset mechanism of the first telescopic rod and the first spring, the circumferential angle adjustment of the dust extraction mechanism can be completed by pulling and rotating, without the need for tools. This ensures that the dust extraction angle will not deviate during the high-speed movement of the robotic arm, improving process flexibility. The sliding seat, in conjunction with the guide rod and the second spring, effectively absorbs the lateral vibration during grinding, preventing the sliding seat from jamming or deviating. The third spring, sleeved on the outside of the lifting rod, can absorb the axial impact force when the follower plate contacts the workpiece, making the lifting action smoother and more gentle.

[0050] 3. In this invention, the flow regulation structure, which combines the adjustment ring and the shielding plate, allows the opening size of the closed slot to be changed by rotating the adjustment ring, thereby controlling the dust suction air volume. This adapts to the chip removal requirements under different cutting volumes, preventing slight deviation of the cutting head or workpiece vibration due to excessive suction during fine grinding, thus ensuring grinding accuracy. The invention also employs a downward clamping unit, utilizing the over-center self-locking characteristic of the linkage mechanism. Compared to traditional screw clamps, this significantly improves clamping speed and maintains constant clamping force, making it suitable for continuous processing of mass-produced wood carvings.

[0058] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0059] Please see Figures 1-5 The present invention provides a technical solution: a grinding device, comprising:

[0060] A processing platform 1 is provided. A mobile module 4 is installed on one side of the processing platform 1. A drive robotic arm 5 is movably connected to the top of the mobile module 4. A grinding head is connected to the movable end of the drive robotic arm 5.

[0061] Control base 6 is connected to the outside of the movable end of the drive robotic arm 5, and moves with the movable end of the drive robotic arm 5 via the control base 6;

[0062] A stabilizing mechanism 8 is connected to the top of the control base 6. A dust extraction mechanism 7 is connected to the top of the stabilizing mechanism 8. The heat dissipation orientation angle of the dust extraction mechanism 7 can be adjusted by the stabilizing mechanism 8.

[0063] The stabilizing mechanism 8 includes:

[0064] Stabilizer 801 is rotatably connected to the top of the control base 6;

[0065] A travel groove 802 is formed on the top of the stabilizer 801;

[0066] The sliding seat 806 is slidably connected in the stroke groove 802. The sliding seat 806 is connected to the lifting rod 812 which can be raised and lowered. The top of the lifting rod 812 is connected to the bottom of the exhaust dust removal mechanism 7. The exhaust dust removal mechanism 7 is dynamically adjusted through the cooperation of the lifting rod 812 and the sliding seat 806.

[0067] Follower plate 813 is used to adjust the position of the exhaust and dust removal mechanism 7 according to the triggering of follower plate 813.

[0068] Specifically: Through the designed stabilizing mechanism 8, when grinding is required, the clamping unit 3 can be inserted into the top of the corresponding insertion platform 2 and limited by the pin. Then, the driving robotic arm 5 moves according to the preset command. At this time, the moving end of the driving robotic arm 5 can grind the wood limited at the top. When grinding, the follower disk 813 can contact the surface of the wood component. When the follower disk 813 moves according to the wood component, it can drive the top exhaust dust removal mechanism 7 to suck up and remove dust. Thus, by adjusting the blowing distance, the wood grinding waste can be fully removed, avoiding contact that is too close or too far, which would affect the removal effect.

[0069] The stabilizing mechanism 8 also includes:

[0070] The first limiting gear 803 and the second limiting gear 810 are connected to the bottom side of the stabilizer 801 and the second limiting gear 810 is connected to the top of the control seat 6. The rotation of the stabilizer 801 is restricted by the meshing of the first limiting gear 803 and the second limiting gear 810.

[0071] The first telescopic rod 804 has its bottom end connected to the groove opened at the top of the control seat 6. The first telescopic rod 804 is fitted with a first spring 805. The two ends of the first spring 805 are respectively connected to the bottom of the inner cavity of the groove and the first limiting gear.

[0072] Furthermore, the opposing surfaces of the first limiting toothed disc 803 and the second limiting toothed disc 810 engage through their teeth;

[0073] Specifically, through the designed stabilizing mechanism 8, when grinding is performed, the first telescopic rod 804 can be extended by pulling the stabilizing frame 801. The extension of the first telescopic rod 804 can pull the external first spring 805. At this time, rotating the stabilizing frame 801 can adjust the angle of the first limiting gear 803 relative to the second limiting gear 810. This is beneficial to achieve circumferential adjustment of the exhaust dust removal mechanism 7 by adjusting the angle of the stabilizing frame 801. In addition, the first spring 805 can be subjected to force to maintain the meshing of the second limiting gear 810 with the first limiting gear 803 by its own tension, providing limiting stability after the angle adjustment.

[0074] The stabilizing mechanism 8 also includes:

[0075] The guide rod 807 is connected to the outside of the sliding seat 806, and the guide rod 807 passes through the guide hole opened in the inner cavity of the stroke groove 802;

[0076] The second spring 808 is sleeved on the outside of the guide rod 807, and the two ends of the second spring 808 are respectively connected to the end of the guide rod 807 and one side of the sliding seat 806;

[0077] A limiting screw 809 is provided. One end of the limiting screw 809 is rotatably connected to a limiting sleeve 816 via a rotating shaft and a bearing. The limiting sleeve 816 fits against one side of the sliding seat 806. The limiting screw 809 is externally threaded to a screw seat, which is embedded on the other side of the stabilizer 801.

[0078] The stabilizing mechanism 8 also includes:

[0079] The third spring 811 is sleeved on the outside of the lifting rod 812. The two ends of the third spring 811 are respectively connected to the sliding seat 806 and one side of the follower disk 813. The third spring 811 absorbs axial impact.

[0080] Specifically: Through the designed guide rod 807 and sliding seat 806, the sliding seat 806 can slide laterally within the stroke groove 802. When the sliding seat 806 slides, it can make fine adjustments to the lateral position of the exhaust dust removal mechanism 7. When the sliding seat 806 moves, it can pull the guide rod 807 to slide, thereby preventing the sliding seat 806 from deviating and improving the stability of the exhaust dust removal mechanism 7. When the guide rod 807 moves, it can compress the external second spring 808. The second spring 808 can use its own elasticity to maintain the stability of the movement of the lifting rod 812.

[0081] Furthermore, by designing the limiting screw 809, the rotating shaft can be rotated within the bearing by rotating the limiting screw 809, thereby preventing the sliding seat 806 from deflecting due to the rotation of the limiting screw 809. When the limiting screw 809 rotates within the screw seat, the front side can be adjusted.

[0082] The stabilizing mechanism 8 also includes:

[0083] Follower rod 814, multiple follower rods 814 are arranged around the axis of follower disk 813, and a rotating block 815 is connected to the top of the follower rod 814. The rotating block 815 is rotatably connected to the groove opened on the periphery of follower disk 813 through a shaft.

[0084] A limiting groove is formed on the top of the follower disk 813. A limiting bolt is threaded into the limiting groove. The limiting bolt is connected to the outside of the shaft to limit the rotation of the shaft.

[0085] Specifically: Through the designed follower rod 814, when the follower plate 813 contacts the component, the follower rod 814 can drive the lifting rod 812 to move upward after contacting the component. The movement of the lifting rod 812 can push the exhaust dust removal mechanism 7 to adjust its axial height, which is conducive to fully contacting the wood grinding area and improving the grinding contact effect.

[0086] Also includes:

[0087] An insertion platform 2 is connected to the top of the processing platform 1. Multiple sets of assembly holes are arranged on the top of the insertion platform 2, and clamping units 3 are provided in the assembly holes.

[0088] The dust extraction and ventilation mechanism 7 includes:

[0089] The blower hood 701 has a sealing plate 705 connected to its inner cavity. The sealing plate 705 has multiple sealing slots around its axis. The blower hood 701 is connected to an external negative pressure suction device through a pipe.

[0090] Adjusting ring 703, with multiple shielding plates 704 connected around the inner cavity along the axis, the closing stroke of shielding plates 704 and the closing groove is controlled by rotating adjusting ring 703;

[0091] The limiting ring 702 is connected to the front side of the blower hood 701. Multiple limiting blocks are connected around the inner periphery of the limiting ring 702. Multiple protrusions are connected around the outer periphery of the adjusting ring 703. The relative angle between the protrusions and the limiting blocks and the contact limit shielding plate 704 is limited.

[0092] Furthermore, the clamping unit 3 is a downward clamping fixture, including a handle and a pressure arm linked by a linkage mechanism. By pushing the handle to the vertical position, the hinge point of the linkage mechanism will cross the center, causing the clamp to self-lock.

[0093] Specifically: Through the designed dust extraction mechanism 7, when dust removal is required, the blower hood 701 can be negatively suctioned by the negative pressure suction device. After suction, the blower hood 701 can suck up the waste chips and discharge them into the waste chip box, which helps to improve the waste chip suction effect. In addition, through the designed adjusting ring 703 and limiting ring 702, the adjusting ring 703 can be rotated inside the blower hood 701. The rotation of the adjusting ring 703 can adjust the inner shielding plate 704 to adjust the shielding stroke relative to the groove, which helps to quickly adjust the negative pressure suction intensity and avoid the suction stress affecting the grinding accuracy of the grinding tool.

Pull down the stabilizer (801) to overcome the tension of the first spring (805), so that the first limiting toothed plate (803) connected to the bottom of the stabilizer (801) and the second limiting toothed plate (810) connected to the top of the control seat (6) are separated, the engagement lock is released, the stabilizer (801) is rotated to the preset angle, so that the exhaust dust removal mechanism (7) faces the best chip removal direction, the stabilizer (801) is released, and under the rebound action of the first spring (805), the first limiting toothed plate (803) and the second limiting toothed plate (810) re-engage, and the angle lock is completed. The limiting screw (809) can be rotated as needed to adjust the initial position of the front side of the sliding seat (806) in the screw seat to prevent the sliding seat (806) from deflecting unexpectedly. S3. Adjust the suction flow rate of the negative pressure suction. Adjust the suction intensity according to the coarseness of the wood carving polishing process. Start the external negative pressure suction equipment and rotate the adjustment ring (703) on the exhaust dust removal mechanism (7). The adjustment ring (703) drives the internal shielding plate (704) to rotate along the axis, changing the shielding area of ​​the shielding plate (704) on the sealing groove of the inner sealing plate (705) of the blower hood (701). Adjust the effective cross section of the air inlet. Lock the current opening size by the cooperation of the protrusion on the adjustment ring (703) and the limiting block on the limiting ring (702) to prevent the suction from being too strong and affecting the grinding accuracy or the suction from being too weak and causing poor chip removal. S4. Adaptive follow-up grinding: Start the moving module (4) and drive the robotic arm (5) to control the grinding head to run according to the preset command trajectory and grind the wood carving components. When the grinding head approaches the wood carving surface, the follower rods (814) arranged around the follower disk (813) will first contact the non-machined surface or reference surface of the wood carving components. As the grinding head moves along the curved surface of the wood carving, the follower rods (814) are subjected to the reaction force of the workpiece surface, driving the follower disk (813) and the lifting rod (812) to slide upward in the sliding seat (806). The lifting rod (812) drives the top The exhaust dust removal mechanism (7) adjusts its axial height synchronously to keep the relative distance between the dust inlet and the grinding point constant, ensuring that the waste is drawn into the blower hood (701) as soon as possible. The third spring (811) absorbs the impact force when the follower plate (813) moves up and down, making the lifting action smooth. When horizontal vibration or displacement occurs during the grinding process, the sliding seat (806) slides along the guide rod (807) in the stroke groove (802) and compresses or stretches the second spring (808), using the elastic force to maintain the lateral stability of the exhaust dust removal mechanism (7) and avoid rigid collision.
