Description

Technical Field

[0001] The present application belongs to the technical field of tool processing, and in particular relates to a welding device and a welding method for a wood processing straight knife. Background Art

[0002] The traditional woodworking industry generally installs woodworking milling cutters in industrial milling machines, computer engraving machines, portable milling machines and other equipment to process non-metallic materials such as logs, artificial boards, organic glass and other furniture and home decoration wires. Traditional woodworking milling cutters are generally straight knives welded together by the cutter body and the blade. The cutter body is made of steel and the blade is made of carbide. The blade generally has two or three edges.

[0003] The existing Chinese patent with publication number CN209736865U discloses a milling cutter welding system with high-precision welding function, which includes a welding equipment body and a workbench, and the welding equipment body is arranged on the workbench, and also includes: a milling cutter, a clamping member and a mounting member, the milling cutter is arranged on the clamping member, the clamping member is arranged on the mounting member near one end of the welding equipment body, the mounting member is arranged on the workbench, and the mounting member is arranged adjacent to the welding equipment body.

[0004] The above-mentioned milling cutter is more stable during welding, but the alloy blade on the milling cutter still needs to be placed manually before welding, and the position of the blade needs to be manually controlled during the welding process, which reduces the safety of the welding process. Summary of the Invention

[0005] The purpose of this application is to address the above-mentioned technical problems and provide a welding device for a wood processing straight knife to perform semi-automatic welding, improve the safety performance during the welding process, and ensure the welding quality of the blade on the straight knife.

[0006] The present application provides a welding device for a woodworking straight knife, comprising:

[0007] Workbench;

[0008] A welding device is placed on a workbench, wherein the welding device is provided with an induction coil;

[0009] Clamping seat, used for clamping the straight knife handle;

[0010] a loading device for feeding the blade into the notch of the straight knife;

[0011] The push assembly is installed on the loading device and is used to position the blade during welding;

[0012] Sliding mechanism, used for moving the loading device and the clamping seat.

[0013] The welding equipment welds the tool handle and the blade through an induction coil, and the tool handle is clamped by a clamping seat to ensure the stability of the welding process. The blade and soft solder are placed in the slot of the tool handle through the loading device to reduce the contact between manual labor and the tool handle, especially when the tool handle is welding the second blade. The tool handle is hot at this time, which improves the safety performance during the welding process. The blade on the loading device is pushed into the slot by the pushing assembly and is positioned against the side wall of the slot. The clamping seat and tool handle are moved by the sliding mechanism to move the tool handle to the position of the induction coil, so that there is enough space for loading the blade before welding.

[0014] Furthermore, the feeding device includes:

[0015] Loading seat;

[0016] The first driving cylinder is used to drive the loading base to move;

[0017] A clamping member provided with a clamping head;

[0018] There are two or more connecting pieces, which are hinged to the loading base and parallel to each other;

[0019] Push the block and place it on the loading seat;

[0020] The driving motor is installed on the loading seat;

[0021] A screw rod is mounted on the output shaft of the driving motor and is adapted to fit the push block;

[0022] Among them, a first spring is arranged between the clamping head and the clamping member, the clamping member is placed at one end of the connecting member, the clamping member and the connecting member are hinged by a rotating shaft, and the push block is at the other end of the connecting member, and the push block and the connecting member are slidingly hinged by the structure of a rotating shaft and a sliding groove.

[0023] The loading seat is driven to move by the first driving cylinder. When the blade and soft solder are placed on the loading seat, the blade is clamped by the clamping member. The first spring and the clamping head are used on the clamping member to improve the clamping force and clamping stability of the clamping member on the blade. The clamping member is connected to the push block through the connecting member, so that the push block moves to control the movement of the clamping member. The push block is controlled to move by the driving motor and the lead screw. When the loading seat clamps the blade and moves toward the tool handle, the clamping member is released, and the push block moves toward the blade, pushing the blade to move in the slot of the tool handle so that the blade is against the side wall of the slot, and then the push block is slightly retracted so that the push block is not affected by the induction coil.

[0024] Furthermore, the pushing component includes:

[0025] A pusher is mounted on the push block, and is used to abut against the blade;

[0026] A first fastener is mounted on the pusher;

[0027] a second spring, disposed between the first latch and the pusher;

[0028] Buffer damping, placed between the pusher and the push block;

[0029] a third spring, disposed between the push member and the push block;

[0030] An ejector, mounted on the loading seat, wherein the ejector is provided with a fourth spring;

[0031] Wherein, the push block is provided with a first card slot adapted to the first card fastener.

[0032] During the welding process, the soft solder melts, which causes the blade position to shift. The blade is pushed to move against the side wall of the slot by the pusher on the push assembly. Before the blade is welded, the pusher pushes the blade to move, and the pusher is locked by the first latch and the first slot. When the first latch is released from the first slot by the ejector, the ejector extends from the pusher block under the action of the third spring and acts on the blade. The pusher moves slowly through the buffer damping to ensure the stability of the blade during movement. When the ejector is separated from the first latch, the first latch is reset by the second spring.

[0033] Furthermore, the pushing assembly further includes:

[0034] The first pushing portion is disposed on the pushing member and on one side of the connecting member;

[0035] A baffle is installed on the push block, and the baffle is in an inverted U shape;

[0036] A second pushing portion is disposed on the baffle and between the two connecting members, the baffle being adapted to the first slot, and the second pushing portion being disposed in the middle of the outer wall of the baffle;

[0037] When the push block moves away from the blade, it pushes the first push part and the push block to move relative to each other, and the relative movement direction is the same as the movement direction of the push block. When the push block moves away from the blade, it pushes the second push part and the push block to move relative to each other, and the relative movement direction is the same as the movement direction of the push block. When the push block moves toward the blade, it pushes the second push part and the push block to move relative to each other, and the relative movement direction is the same as the movement direction of the push block.

[0038] When the pushing block moves to make the clamping member clamp the blade, the first pushing part is retracted into the pushing block under the action of the connecting member, and is locked by the first clamping member and the first clamping groove, the connecting member pushes the second pushing part to make the baffle move and block between the first clamping member and the ejector, when the pushing block pushes the blade to position for the first time, the first clamping member moves through the position of the ejector without being contacted and locked, when the pushing block completes the first positioning movement, the connecting member pushes the second pushing part to open the baffle, and the pushing block is retracted to make the first clamping member not pass through the position of the ejector, when the pushing member needs to be ejected, the pushing block moves to make the ejector correspond to the first clamping member to extend the pushing member to abut against the blade, so that the blade is repositioned.

[0039] Further, the ejector is provided with a hinged member hinged to the upper loading seat, the ejector is movably connected with the hinged member, the fourth spring is arranged between the ejector and the hinged member, and the ejector is provided with an arc-shaped handle.

[0040] The hinged member is retracted to reduce the friction between the pushing member and the ejector during the movement of the pushing member, so as to ensure the stable movement of the pushing member, and the handle is acted on by the connecting member to make the hinged member rotate to eject the ejector.

[0041] Further, the pushing member comprises:

[0042] The first pushing rod is provided with two or more than two, and the axis thereof is perpendicular to the axis of the tool handle;

[0043] The second pushing rod is provided with one or more than one, and the axis thereof is parallel to the axis of the tool handle;

[0044] The buffer damping comprises a first buffer cavity and a second buffer cavity, the first buffer cavity corresponds to the first pushing rod, the second buffer cavity corresponds to the second pushing rod, a buffer solution is arranged in the first buffer cavity and the second buffer cavity, and the first buffer cavity and the second buffer cavity are in communication.

[0045] When the pushing member is unlocked from the pushing block, the first pushing rod is extended under the action of the third spring, and at the same time, the buffer solution in the first buffer cavity is transported into the second buffer cavity, so that the second pushing rod is extended outward, and the first pushing rod and the second pushing rod correct the deviation of the blade during the welding process.

[0046] Further, the sliding mechanism comprises:

[0047] The first sliding rail is mounted on the workbench;

[0048] The first sliding seat is matched with the first sliding rail;

[0049] The second sliding rail is mounted on the first sliding seat;

[0050] a second slide seat adapted to the second slide rail;

[0051] A second driving cylinder is installed between the workbench and the first slide;

[0052] Among them, the axis of the first slide rail is perpendicular or parallel to the axis of the straight knife, the axis of the second slide rail is at 45° to the axis of the first slide rail, the clamping seat is installed on the first slide, the loading seat is installed on the second slide, and the first driving cylinder is placed between the second slide and the first slide.

[0053] The movement of the clamping seat is controlled by the first slide rail, the first slide seat, and the second driving cylinder to realize the movement of the welding tool handle. The movement of the loading device is controlled by the second slide rail, the second slide seat, and the first driving cylinder to realize the movement of the blade toward the tool handle during loading. The axis of the second slide rail is 45° to the axis of the first slide rail, which facilitates the simultaneous separation of the first push rod and the second push rod when they are pushed and separated, preventing the blade from being offset by friction between each other during separation, thereby ensuring the stability of the blade after positioning.

[0054] The present application also provides a welding method for a welding device for a woodworking straight knife, the specific steps of which include:

[0055] S1, turn on the soldering equipment, clamp the tool handle through the clamping seat, prepare soft solder and the blade, apply flux between the soft solder and the blade, place the soft solder and the blade on the loading seat, and then clamp them through the clamping piece;

[0056] S2, the clamping seat and the blade are moved to the notch of the tool handle through the sliding mechanism, the clamping member is released, the push block is pushed out to place the blade in the notch and move it so that the blade abuts against the side wall of the notch, and then the push block is retracted;

[0057] S3, push the knife handle to the corresponding position of the induction coil through the sliding mechanism, and heat the knife handle and the blade by the induction coil of the welding equipment. When the soft solder melts, move the push block to the position where the connecting piece and the handle abut against each other, extend the first push rod and the second push rod to abut against the blade, so that the blade moves again to abut against the side wall of the notch, and then moves away from the knife handle through the sliding mechanism. After the movement is completed, the loading base is moved away from the knife handle through the sliding mechanism to continue welding;

[0058] S4, after the welding is completed, the tool handle is moved away from the induction coil through the sliding mechanism, and then the tool handle is rotated 180 degrees through the clamping seat, and soft solder and the blade are placed on the loading seat, and the above welding work is continued. After all the blades on the tool handle are welded, the tool handle is removed from the clamping seat.

[0059] Before welding, the blade is initially positioned by pushing the block, and the blade is re-positioned during welding to improve the position accuracy of the blade after welding and the welding stability between the blade and the handle. The induction coil welding heating only acts on the blade and the notch position rather than the entire handle. The two blades are heated twice when welding to achieve one-by-one welding of the blades on the handle.

[0060] The beneficial effects of this application are:

[0061] 1. After the blade and soft solder are placed on the loading seat, the blade is clamped by the clamping piece, and then the loading seat is driven to move by the first driving cylinder. The push block is controlled to move by the driving motor and the screw rod. When the loading seat clamps the blade and moves toward the tool handle, the clamping piece is released, and the push block moves toward the blade, pushing the blade to move in the slot of the tool handle.

[0062] 2. When the soft solder melts during the welding process, the pusher on the push assembly pushes the blade to move against the side wall of the notch and acts on the blade. The pusher moves slowly through the buffer damping and the third spring to ensure the stability of the blade during movement.

[0063] 3. When the push block moves to make the clamping member clamp the blade, the first pushing part contracts into the push block under the action of the connecting member, and is locked with the first slot through the first fastener. The connecting member pushes the second pushing part to move the baffle to be blocked between the first fastener and the ejector. When the push block completes the first positioning movement of the blade, the connecting member pushes the second pushing part to open the baffle.

[0064] 4. When the push member is released from the locking state with the push block, the first push rod extends downward under the action of the third spring, and at the same time, the buffer solution in the first buffer chamber is transported to the second buffer chamber, causing the second push rod to extend outward. The offset of the blade during the welding process is corrected by the first push rod and the second push rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0073] The following provides a detailed description of the embodiments of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0074] Example 1:

[0075] like Figure 1 、 Figure 2 As shown, the embodiment of the present application provides a welding device for a woodworking straight knife, comprising:

[0076] Workbench 100;

[0077] The welding device 200 is placed on the workbench 100 and is provided with an induction coil 210;

[0078] A clamping seat 300 is used to clamp the handle of a straight knife;

[0079] a loading device 400 for feeding the blade into the notch of the straight knife;

[0080] The push assembly 500 is mounted on the loading device 400 and is used to position the blade during the welding process;

[0081] The sliding mechanism 600 is used to move the loading device 400 and the clamping seat 300 .

[0082] The welding equipment 200 welds the tool handle and the blade through the induction coil 210, and the tool handle is clamped by the clamping seat 300 to ensure the stability of the welding process. The blade and soft solder are placed in the slot of the tool handle through the loading device 400 to reduce the contact between manual labor and the tool handle, especially when the tool handle is welding the second blade. The tool handle is hot at this time, which improves the safety performance during the welding process. The blade on the loading device 400 is pushed into the slot by the pushing component 500 and is positioned against the side wall of the slot. The clamping seat 300 and the tool handle are moved by the sliding mechanism 600 to the position of the induction coil 210, so that there is enough space for loading the blade before welding.

[0083] Example 2:

[0084] like Figure 2 As shown, the embodiment of the present application provides a welding device for a woodworking straight knife. In addition to the above technical features, the feeding device 400 further includes:

[0085] Loading seat 410;

[0086] The first driving cylinder 420 is used to drive the loading base 410 to move;

[0087] The clamping member 430 is provided with a clamping head 431;

[0088] There are two or more connecting members 440 , which are hinged to the loading base 410 , and the connecting members 440 are parallel to each other;

[0089] The push block 450 is placed on the loading seat 410;

[0090] The driving motor 460 is mounted on the loading base 410;

[0091] The screw rod 470 is mounted on the output shaft of the driving motor 460 and is adapted to fit the push block 450 ;

[0092] Among them, a first spring 432 is arranged between the clamping head 431 and the clamping member 430, the clamping member 430 is placed at one end of the connecting member 440, and the clamping member 430 and the connecting member 440 are hinged by a rotating shaft, and the push block 450 is at the other end of the connecting member 440, and the push block 450 and the connecting member 440 are slidingly hinged by the structure of a rotating shaft and a sliding groove.

[0093] The loading base 410 is driven to move by the first driving cylinder 420. When the blade and soft solder are placed on the loading base 410, the blade is clamped by the clamping member 430. The first spring 432 and the clamping head 431 on the clamping member 430 increase the clamping force and clamping stability of the clamping member 430 on the blade. The clamping member 430 is connected to the pushing block 450 through the connecting member 440, so that the pushing block 450 moves to control the movement of the clamping member. The pushing block 450 is controlled to move by the driving motor 460 and the screw rod 470. When the loading base 410 clamps the blade and moves toward the tool handle, the clamping member 430 is released, and the pushing block 450 moves toward the blade, pushing the blade to move in the slot of the tool handle so that the blade is against the side wall of the slot, and then the pushing block 450 is slightly retracted so that the pushing block 450 is not affected by the induction coil 210.

[0094] Example 3:

[0095] like Figure 2 、 Figure 3 、 Figure 4 As shown, the embodiment of the present application provides a welding device for a woodworking straight knife. In addition to the above technical features, the pushing assembly 500 further includes:

[0096] A pusher 510 is mounted on the push block 450 and is used to abut against the blade;

[0097] The first locking member 520 is mounted on the pushing member 510;

[0098] The second spring 530 is disposed between the first latch 520 and the pusher 510;

[0099] The buffer damper 540 is placed between the pusher 510 and the push block 450;

[0100] A third spring 550 is disposed between the pusher 510 and the push block 450;

[0101] The ejector 560 is mounted on the loading seat 410 and is provided with a fourth spring 561;

[0102] The push block 450 is provided with a first latching slot 411 adapted to the first latching member 520 .

[0103] During the welding process, the soft solder melts, which will cause the blade position to shift. The pusher 510 on the push assembly 500 pushes the blade to move until it is against the side wall of the slot. Before the blade is welded, the push block 450 pushes the blade to move, and the pusher 510 is locked by the first latch 520 and the first slot 411. When the first latch 520 is released from the first slot 411 by the ejector 560, the pusher 510 extends from the push block 450 under the action of the third spring 550 and acts on the blade. The buffer damper 540 allows the pusher 510 to move slowly to ensure the stability of the blade during movement. When the ejector 560 is separated from the first latch 520, the first latch 520 is reset by the second spring 530.

[0104] Furthermore, the pushing assembly 500 further includes:

[0105] The first pushing portion 511 is disposed on the pushing member 510 and on one side of the connecting member 440;

[0106] The baffle 570 is mounted on the push block 450 and is in the shape of an inverted Chinese character;

[0107] The second pushing portion 571 is placed on the baffle 570 and between the two connecting members 440. The baffle 570 is adapted to the first slot 411. The second pushing portion 571 is placed in the middle of the outer wall of the baffle 570.

[0108] Among them, when the push block 450 moves in the direction away from the blade, it pushes the first pushing part 511 and the push block 450 to move relative to each other, and the relative movement direction is the same as the movement direction of the push block 450. When the push block 450 moves in the direction away from the blade, it pushes the second pushing part 571 and the push block 450 to move relative to each other, and the relative movement direction is the same as the movement direction of the push block 450. When the push block 450 moves in the direction close to the blade, it pushes the second pushing part 571 and the push block 450 to move relative to each other, and the relative movement direction is the same as the movement direction of the push block 450.

[0109] When the push block 450 moves to make the clamping member 430 clamp the blade, the first pushing portion 511 shrinks into the push block 450 under the action of the connecting member 440, and is locked with the first card slot 411 through the first latch 520. The connecting member 440 pushes the second pushing portion 571 to move the baffle 570 to block between the first latch 520 and the ejector 560. When the push block 450 pushes the blade to position for the first time, the first latch 520 moves through the position of the ejector 560. It will be in a contact locked state. When the push block 450 completes the first positioning movement of the blade, the connecting member 440 pushes the second pushing portion 571 to open the baffle 570. After the push block 450 completes the first positioning, the retracted position makes the first latch 520 not pass through the position of the ejector 560. When the push member 510 needs to be ejected, the push block 450 moves so that the ejector 560 corresponds to the first latch 520, and the push member 510 is extended to press against the blade, so that the blade is repositioned.

[0110] Example 4:

[0111] like Figure 4 As shown, an embodiment of the present application provides a welding device for a wood processing straight knife. In addition to the above-mentioned technical features, the ejector 560 is further provided with a hinge 562, and the hinge 562 is hinged to the loading base 410. The ejector 560 and the hinge 562 are movably connected, and the fourth spring 561 is placed between the ejector 560 and the hinge 562. The ejector 560 is provided with an arc-shaped handle 563.

[0112] The ejector 560 is contracted by the hinge 562 to reduce the friction between the pusher 510 and the ejector 560 during movement, thereby ensuring stable movement of the pusher 510. The connector 440 acts on the handle 563 to rotate the hinge 562 to eject the ejector 560.

[0113] Example 5:

[0114] like Figure 2 、 Figure 5 As shown, the embodiment of the present application provides a welding device for a woodworking straight knife. In addition to the above technical features, the pusher 510 further includes:

[0115] There are two or more first push rods 512, and their axes are perpendicular to the axis of the handle;

[0116] There is one or more second push rods 513, and the axis thereof is parallel to the axis of the knife handle;

[0117] In which, the buffer damping 540 includes a first buffer chamber 541 and a second buffer chamber 542. The first buffer chamber 541 corresponds to the first push rod 512, and the second buffer chamber 542 corresponds to the second push rod 513. Buffers are provided in the first buffer chamber 541 and the second buffer chamber 542, and the first buffer chamber 541 and the second buffer chamber 542 are connected to each other.

[0118] When the push member 510 is released from the locking state with the push block 450, the first push rod 512 extends downward under the action of the third spring 550, and at the same time transports the buffer in the first buffer chamber 541 into the second buffer chamber 542, so that the second push rod 513 extends outward, and the offset of the blade during the welding process is corrected by the first push rod 512 and the second push rod 513.

[0119] Example 6:

[0120] like Figure 1 As shown, the embodiment of the present application provides a welding device for a woodworking straight knife. In addition to the above technical features, the sliding mechanism 600 further includes:

[0121] The first slide rail 610 is installed on the workbench 100;

[0122] A first slide 620 adapted to the first slide rail 610;

[0123] The second slide rail 630 is mounted on the first slide seat 620;

[0124] The second slide 640 is adapted to the second slide rail 630;

[0125] The second driving cylinder 650 is installed between the workbench 100 and the first slide 620;

[0126] Among them, the axis of the first slide rail 610 is perpendicular or parallel to the axis of the straight knife, the axis of the second slide rail 630 is at 45° to the axis of the first slide rail 610, the clamping seat 300 is installed on the first slide 620, the loading seat 410 is installed on the second slide 640, and the first drive cylinder 420 is placed between the second slide 640 and the first slide 620.

[0127] The movement of the clamping seat 300 is controlled by the first slide rail 610, the first slide seat 620, and the second drive cylinder 650 to realize the movement of the welding tool handle. The movement of the loading device 400 is controlled by the second slide rail 630, the second slide seat 640, and the first drive cylinder 420 to realize the movement of the blade toward the tool handle during loading. The axis of the second slide rail 630 is 45° to the axis of the first slide rail 610, which facilitates the first push rod 512 and the first push rod 512 to separate at the same time after pushing and separating, preventing the blade from being offset due to mutual friction during separation, and ensuring the stability of the blade after positioning.

[0128] Example 7:

[0129] The present application also provides a welding method for a welding device for a woodworking straight knife, the specific steps of which include:

[0130] S1, open the soldering device 200, clamp the knife handle through the clamping seat 300, prepare soft solder and knife blade, apply flux between the soft solder and the knife blade, place the soft solder and the knife blade on the loading seat 410, and then clamp them with the clamping member 430;

[0131] S2, the clamping seat 300 and the blade are moved to the notch of the shank by the sliding mechanism 600, the clamping member 430 is released, the push block 450 is pushed out to place the blade in the notch and move it so that the blade abuts against the side wall of the notch, and then the push block 450 is retracted;

[0132] S3, the knife handle is pushed to the corresponding position of the induction coil 210 by the sliding mechanism 600, and the induction coil 210 of the welding device 200 is used to heat the knife handle and the blade. When the soft solder melts, the push block 450 is moved to the position where the connecting member 440 and the handle 563 abut each other, and the first push rod 512 and the second push rod 513 are extended to abut against the knife blade, so that the knife blade moves again to abut against the side wall of the notch, and then the sliding mechanism 600 is used to move the knife handle away from the knife handle. After the movement is completed, the sliding mechanism 600 is used to move the loading base 410 away from the knife handle to continue welding;

[0133] S4, after the welding is completed, the tool handle is moved away from the induction coil 210 through the sliding mechanism 600, and then the tool handle is rotated 180 degrees through the clamping seat 300, and soft solder and the blade are placed on the loading seat 410, and the above welding work is continued. After all the blades on the tool handle are welded, the tool handle is removed from the clamping seat 300.

[0134] Before welding, the blade is initially positioned by the push block 450, and the blade is re-positioned during the welding process, thereby improving the position accuracy of the blade after welding and improving the welding stability between the blade and the handle. The welding heating of the induction coil 210 only acts on the blade and the notch position rather than the entire handle. The two blades are heated twice when welding, thereby realizing the welding of the blades on the handle one by one.
