Description

Technical Field

[0001] This application relates to the field of blade manufacturing technology, and in particular to a blade welding apparatus. Background Technology

[0002] With the continuous advancement of precision and ultra-precision machining technologies, the application of difficult-to-machine materials is becoming increasingly widespread in fields such as aerospace, energy equipment, military industry, mold manufacturing, and the automotive industry. At the same time, the rapid popularization of high-speed CNC machining technology has placed higher demands on the performance of cutting tools. Traditional inserts are gradually becoming insufficient to meet the needs of modern manufacturing in terms of machining efficiency, precision, and durability. Against this backdrop, superhard inserts, due to their high hardness, excellent wear resistance, and stable cutting performance, are widely used in fields such as machining, geological exploration, and energy extraction.

[0003] Superhard cutting inserts are typically made by brazing a superhard cutting tip to the insert substrate. In actual cutting processes, detachment from the substrate becomes one of the main failure modes of cutting inserts; therefore, the quality of the brazing directly affects the overall performance and service life of the insert. Currently, the brazing of the cutting tip and substrate is generally done manually or using a combination of manual and mechanical methods. However, manual operation is inefficient, physically demanding for operators, highly dependent on operator skill, difficult to guarantee process consistency, and prone to significant fluctuations in weld quality. Summary of the Invention

[0004] In view of this, this application provides a blade welding device to solve, to some extent, the problems existing in manual or combined manual and mechanical brazing methods.

However, various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will be apparent after understanding the disclosure of this application. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein; changes that will be apparent after understanding the disclosure of this application are possible, except for operations that must occur in a specific order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0020] The features described herein may be implemented in different forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein have been provided merely to illustrate some of the many feasible ways of implementing the methods, apparatus, and / or systems described herein that will be apparent upon understanding the disclosure of this application.

[0021] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, or there may be one or more other elements in between. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly bonded to" another element, "directly on" another element, or "directly covering" another element, there may be no other elements in between.

[0022] As used herein, the term “and / or” includes any one of the relevant items listed and any combination of any two or more items.

[0023] Although terms such as “first,” “second,” and “third” may be used herein to describe individual components, modules, regions, layers, or parts, these components, modules, regions, layers, or parts are not limited by these terms. Rather, these terms are used only to distinguish one component, module, region, layer, or part from another. Therefore, without departing from the teachings of the examples described herein, the first component, module, region, layer, or part referred to as the second component, module, region, layer, or part may also be referred to as the second component, module, region, layer, or part.

Therefore, the term “above” includes both “above” and “below” orientations depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relation terms used herein will be interpreted accordingly.

[0028] This application provides a blade welding device, such as Figures 1 to 8As shown, the blade welding device is used to weld the blade head 7 and the blade substrate 6. The blade substrate 6 has a mounting groove, and the blade head 7 needs to be installed in the mounting groove. The blade welding device includes an installation module 1, a feeding module 2, a coating module 3, a welding module 4, and a unloading module 5. The installation module 1 includes a rotary drive 11 and an installation mechanism 12. The installation mechanism 12 is used to install the blade substrate 6. The rotary drive 11 can drive the installation mechanism 12 to rotate, so that the installation mechanism 12 can move between the feeding position, the coating position, the welding position, and the unloading position. The feeding module 2 includes a first receiving component 21 and a feeding component 22. The first receiving component 21 is used to receive the blade substrate 6. When the installation mechanism 12 moves to the feeding position, the feeding component 22 can place the blade substrate 6 in the first receiving component 21 onto the installation mechanism 12. When the mounting mechanism 12 moves to the coating position, the coating module 3 coats the blade substrate 6 with brazing filler metal and flux. The welding module 4 includes a second receiving component 41, a welding component 42, and a cutting head moving component 43. The second receiving component 41 is used to receive the cutting head 7. When the mounting mechanism 12 moves to the welding position, the cutting head moving component 43 can move the cutting head 7 from the second receiving component 41 onto the blade substrate 6. The welding component 42 can heat the cutting head 7 and the blade substrate 6 to connect them and form a blade. The unloading module 5 includes a receiving component 51 and an unloading component 52. When the mounting mechanism 12 moves to the unloading position, the unloading component 52 can move the blade into the receiving component 51. Thus, this application improves welding efficiency and reduces the labor intensity of operators by replacing manual operation with a blade welding device. At the same time, the blade welding device of this application avoids dependence on operator skills, improves process consistency, and ensures welding quality.

[0029] In the embodiments of this application, such as Figure 2 and Figure 3As shown, the mounting mechanism 12 includes a turntable 121, a mounting member 122, and a moving member 123. A rotary drive member 11 is fixed to a support frame 17. The output shaft of the rotary drive member 11 is connected to the turntable 121 via a rotating shaft to drive the turntable 121 to rotate. The mounting member 122 is fixed to the outer wall of the turntable 121. The moving member 123 includes a supporting portion 1231 and an abutting portion 1232. The abutting portion 1232 is connected to the end of the supporting portion 1231 away from the rotating shaft. The thickness of the supporting portion 1231 is less than the thickness of the abutting portion 1232, causing a portion of the abutting portion 1232 to protrude upwards relative to the supporting portion 1231. The supporting portion 1231 supports the blade base 6 and is slidably connected to the mounting member 122, allowing the supporting portion 1231 to move radially along the turntable 121. When the mounting mechanism 12 moves to the loading and unloading positions, the distance between the abutment portion 1232 and the mounting member 122 is greater than the radial dimension of the blade base 6, so as to facilitate placing the blade base 6 on the support portion 1231 or removing the already welded blade. When the mounting mechanism 12 moves to the coating and welding positions, the two ends of the blade base 6 in the radial direction abut against the mounting member 122 and the abutment portion 1232 respectively. At this time, the abutment portion 1232 and the mounting member 122 cooperate to fix the blade base 6, so as to facilitate the coating of brazing filler metal and flux and welding.

[0030] Optionally, the upper surface of the support portion 1231 is provided with a texture, preferably a strip texture.

[0031] Optionally, the rotary drive 11 is a motor; preferably, the rotary drive 11 is a closed-loop stepper motor.

[0032] like Figure 3 As shown, the mounting member 122 has a guide groove 1221 that extends radially. A portion of the support portion 1231 is located within the guide groove 1221 and is movable relative to the guide groove 1221. Thus, the guide groove 1221 can guide the movement of the moving member 123 to ensure that the moving member 123 can move radially.

[0033] Optionally, the turntable 121 includes a base plate 1211 and a surrounding member 1212. The base plate 1211 is connected to the rotation drive member 11, and the surrounding member 1212 surrounds the base plate 1211 for a circumference. The surrounding member 1212 has a through hole.

[0034] like Figure 2 and Figure 3As shown, the mounting module 1 also includes an adapter 14 and a cam 15. The adapter 14 passes through a through hole, and the cam 15 can be fixed to the support frame 17 by bolts. The cam 15 is located within the space enclosed by the base plate 1211 and the surrounding member 1212. The cam 15 has a mounting hole, through which the rotating shaft passes and connects to the base plate 1211. A tapered roller bearing 16 is provided between the cam 15 and the rotating shaft. The adapter 14 contacts the outer wall of the cam 15 and can slide along the outer wall of the cam 15. The cam 15 includes a first contact position 151, a second contact position 152, a third contact position 153, and a fourth contact position 154. In the direction from the first contact position 151 to the second contact position 152, the radius of the cam 15 gradually decreases. In the direction from the second contact position 152 to the third contact position 153, the radius of the cam 15 remains unchanged. In the direction from the third contact position 153 to the fourth contact position 154, the radius of the cam 15 gradually increases. In the direction from the fourth contact position 154 to the first contact position 151, the radius of the cam 15 remains unchanged. That is, the radius of the cam 15 is largest in the part between the first contact position 151, the fourth contact position 154, and the part between the first contact position 151 and the fourth contact position 154, and the radius of the cam 15 is smallest in the part between the second contact position 152, the third contact position 153, and the part between the second contact position 152 and the third contact position 153. Thus, when the mounting mechanism 12 is in the feeding position, the adapter 14 contacts the first contact position 151 of the cam 15, and the distance between the adapter 14 and the axis of the cam 15 is at its maximum. At this time, the distance between the abutment portion 1232 and the mounting member 122 is at its maximum, which facilitates the feeding assembly 22 to place the blade substrate 6 on the support. As the mounting mechanism 12 moves from the feeding position to the coating position, the distance between the adapter 14 and the axis of the cam 15 gradually decreases, and the abutment portion 1232 and the mounting member 122 gradually approach each other. When the mounting mechanism 12 moves to the coating position, the two ends of the blade substrate 6 in the radial direction abut against the mounting member 122 and the abutment portion 1232 respectively to position the blade substrate 6. At this time, the coating module 3 can coat the blade substrate 6 with solder and flux. Afterwards, the mounting mechanism 12 moves from the coating position to the welding position. The distance between the adapter 14 and the axis of the cam 15 remains unchanged. The mounting part 122 and the abutment part 1232 maintain the state of clamping the blade base 6. When moving to the welding position, the welding assembly 42 can heat the blade head 7 and the blade base 6 to connect the blade head 7 and the blade base 6 to form a blade. After welding is completed, the mounting mechanism 12 moves to the unloading position. At this time, the distance between the adapter 14 and the axis of the cam 15 gradually increases, and the abutment part 1232 and the mounting part 122 gradually move away to release the blade. When moving to the unloading position, the distance between the adapter 14 and the axis of the cam 15 is the largest, and the distance between the abutment part 1232 and the mounting part 122 is the largest, which facilitates the unloading assembly 52 to move the blade into the receiving assembly 51.

[0035] Optionally, the adapter 14 includes an adapter rod 141 and a roller 142. The adapter rod 141 is connected to the support portion 1231, and the roller 142 is disposed at the end of the adapter rod 141. The roller 142 contacts the outer wall of the cam 15 to ensure that the adapter 14 can move smoothly along the outer wall of the cam 15. Optionally, the roller 142 can be a ball joint.

[0036] In addition, the adapter 14 also includes a protrusion 143, which protrudes from the outside of the adapter rod 141. The mounting module 1 also includes an elastic member 13, which is sleeved on the adapter rod 141. One end of the elastic member 13 abuts against the protrusion 143, and the other end of the elastic member 13 abuts against the side of the surround member 1212 facing the cam 15. The elastic member 13 is in a compressed state, which allows the elastic member 13 to apply force to the adapter rod 141 to ensure that the roller 142 is always in contact with the outer wall of the cam 15.

[0037] Preferably, the elastic element 13 is a spring, and its material is spring steel.

[0038] Furthermore, the abutment portion 1232 has a groove 1222 facing the mounting member 122, and a portion of the blade base 6 can be inserted into the groove 1222. In this way, the groove 1222 is adapted to the shape of the tip of the blade base 6, which can improve the stability of the blade base 6.

[0039] Optionally, there may be multiple mounting mechanisms 12, which are equidistantly spaced along the circumference of the turntable 121, and each mounting mechanism 12 is provided with a corresponding adapter 14. Preferably, there are four mounting mechanisms 12.

[0040] In the embodiments of this application, such as Figure 1 and Figure 5 As shown, the feeding module 2 also includes a blade substrate conveyor belt 23. The first receiving component 21 includes a first vibratory feeder 211 and a first connecting track 212. The blade substrate 6 is placed inside the first vibratory feeder 211. One end of the first connecting track 212 is connected to the first vibratory feeder 211, and the other end extends to the blade substrate conveyor belt 23. When the first vibratory feeder 211 discharges material, the blade substrate 6 moves onto the blade substrate conveyor belt 23 via the first connecting track 212.

[0041] Furthermore, a first positioning detector 24 is provided on the side of the blade substrate conveyor belt 23 to detect the position of the blade substrate 6. Optionally, the first positioning detector 24 can be a laser photoelectric switch.

[0042] In addition, the feeding module 2 also includes a stabilizing frame 25 and a connecting plate 26. The connecting plate 26, the blade base conveyor belt 23, and the feeding assembly 22 are all mounted on the stabilizing frame 25. The feeding assembly 22 includes a gripping cylinder 221, a rotating cylinder 222, a push-pull cylinder 223, and a moving cylinder 224. The gripping cylinder 221, the rotating cylinder 222, the push-pull cylinder 223, and the moving cylinder 224 are connected in sequence by threads. The moving cylinder 224 is mounted on the connecting plate 26. The gripping cylinder 221 can grip the blade base 6 on the blade base conveyor belt 23 and move the blade base 6 to the support part 1231 under the drive of the rotating cylinder 222, the push-pull cylinder 223, and the moving cylinder 224.

[0043] Preferably, the gripping cylinder 221 is a thin-type pneumatic gripper cylinder, the push-pull cylinder 223 is a double cylinder, and the moving cylinder 224 is a magnetically coupled rodless cylinder.

[0044] Optionally, the blade base conveyor belt 23 stops when the blade base 6 moves to a position where it can be gripped, so as to facilitate gripping.

[0045] In the embodiments of this application, such as Figure 1 As shown, the coating module 3 includes a flux applicator 31 and a solder applicator 32, which are mounted on a coating cylinder 33. The coating cylinder 33 drives the flux applicator 31 and the solder applicator 32 to move, respectively coating the grooves 1222 of the blade substrate 6 with solder and flux. Optionally, during coating, the coating cylinder 33 first drives the flux applicator 31 and the solder applicator 32 to move until the position of the flux applicator 31 corresponds to the mounting groove of the blade substrate 6, so as to apply flux to the mounting groove of the blade substrate 6. After the flux coating is completed, the coating cylinder 33 drives the flux applicator 31 and the solder applicator 32 to move until the position of the solder applicator 32 corresponds to the mounting groove of the blade substrate 6, so as to apply solder to the mounting groove of the blade substrate 6.

[0046] Preferably, the coating cylinder 33 is a magnetically coupled rodless cylinder to ensure the movement accuracy of the flux coating machine 31 and the solder coating machine 32. The flux coating machine 31 and the solder coating machine 32 can be automatic dispensing machines to ensure the coating accuracy of the flux and solder.

[0047] like Figure 1 and Figure 6As shown, the second receiving assembly 41 includes a second vibratory plate 411 and a second connecting rail 412. A cutter head 7 is placed inside the second vibratory plate 411, and the second connecting rail 412 is connected to the second vibratory plate 411. A welding surface detector 413 is provided on the second vibratory plate 411 near the second connecting rail 412. The welding surface detector 413 is used to detect the orientation of the cutter head 7. If the orientation of the cutter head 7 is incorrect, the second vibratory plate 411 can prevent the cutter head 7 from being discharged, thus ensuring the correct orientation of the cutter head 7.

[0048] Preferably, the welding surface detector 413 is an optical fiber sensor.

[0049] like Figure 1 and Figure 6 As shown, the welding module 4 includes a connecting plate 44, a conveying assembly 45, and a cutting head feeding conveyor belt 46. The conveying assembly 45 can drive the connecting plate 44 to move, and the cutting head feeding conveyor belt 46 is disposed on the connecting plate 44. The welding assembly 42 includes a power supply 421 and an induction heating coil 422. Both the power supply 421 and the induction heating coil 422 are fixed on the connecting plate 44, and the power supply 421 is connected to the induction heating coil 422. Before the mounting mechanism 12 moves to the welding position, the conveying assembly 45 drives the connecting plate 44 to move, causing the cutting head feeding conveyor belt 46 to separate from the second connecting track 412. When the mounting mechanism 12 moves to the welding position, the conveying assembly 45 drives the connecting plate 44 to move, causing the induction heating coil 422 to be sleeved on the blade base 6. At this time, the cutting head feeding conveyor belt 46 contacts the second connecting track 412, and the upper surface of the cutting head feeding conveyor belt 46 is flush with the upper surface of the abutment part 1232. Then, the second vibratory feeder 411 can feed the cutter head 7, causing the cutter head 7 to move onto the cutter head feeding conveyor belt 46, and move towards the side where the blade base 6 is located under the drive of the cutter head feeding conveyor belt 46. After the cutter head 7 is in place, the power supply 421 is turned on, and the induction heating coil 422 heats the cutter head 7 and the blade base 6 to connect the cutter head 7 and the blade base 6.

[0050] Preferably, the power supply 421 is a high-frequency induction heating power supply.

[0051] In addition, a second position detector 472 is provided on the side of the feed conveyor belt 46 for detecting the position of the cutter head 7. Optionally, the second position detector 472 can be a laser photoelectric switch.

[0052] like Figure 1 , Figure 6 and Figure 8As shown, the cutter head moving assembly 43 includes a translation drive mechanism 431 and a pusher block 432. The translation drive mechanism 431 is fixed on the connecting plate 44 and connected to the pusher block 432 to drive the pusher block 432 to move. The pusher block 432 is used to abut against the cutter head 7. In this way, the translation drive mechanism 431 can drive the pusher block 432 to move, and the pusher block 432 can push the cutter head 7 on the cutter head feeding conveyor belt 46 into the mounting groove of the blade base 6 through the abutment part 1232.

[0053] Optionally, the pusher block 432 is formed with a notch adapted to the shape of the cutter head 7.

[0054] In addition, when the cutter head 7 is moved, the second vibratory plate 411 and the blade base conveyor belt 23 stop to facilitate the movement of the cutter head 7.

[0055] Optionally, the translation drive mechanism 431 includes a cutter head push rod 4311, a cutter head thrust sensor 4312, a first crank-connecting rod mechanism 4313, and a first motor 4314, which are connected in sequence. Under the drive of the first motor 4314, the first crank-connecting rod mechanism 4313, the cutter head thrust sensor 4312, the cutter head push rod 4311, and the push block 432 can move, thereby pushing the cutter head 7 to move.

[0056] like Figure 1 , Figure 6 and Figure 7 As shown, the welding module 4 also includes a pressure-applying component 48 and a pressure-applying driving mechanism 49. The pressure-applying component 48 is rod-shaped, and the pressure-applying driving mechanism 49 is fixed on the connecting plate 44. The pressure-applying driving mechanism 49 is connected to the pressure-applying component 48 to drive the pressure-applying component 48 to move. The pressure-applying component 48 is used to contact the cutting head 7. In this way, when the induction heating coil 422 is heating, the pressure-applying component 48 can apply force to the cutting head 7 to improve the stability of the connection between the cutting head 7 and the blade base 6.

[0057] Optionally, the pressure-applying drive mechanism 49 includes a cutter head pressure sensor 491, a second crank-connecting rod mechanism 492, and a second motor 493. The pressure-applying component 48, the cutter head pressure sensor 491, the second crank-connecting rod mechanism 492, and the second motor 493 are sequentially connected. Driven by the second motor 493, the pressure-applying component 48 can move to contact the cutter head 7, thereby applying force to the cutter head 7.

[0058] In addition, the welding module 4 also includes a temperature measuring element 471, which is fixed on the connecting plate 44. The temperature measuring element 471 is used to detect the temperature of the cutting head 7 so as to monitor the heating temperature in real time.

[0059] Optionally, the temperature measuring element 471 is an infrared thermometer, and the blade pressure sensor 491 is an S-type miniature tensile and pressure sensor.

[0060] After welding is completed, the mounting mechanism 12 moves to the unloading position to unload the material. At this time, the storage component 51 is located under the mounting mechanism 12. The unloading component 52 pushes the blade so that the blade falls into the storage component 51, thereby completing the unloading.

[0061] Optionally, the storage component 51 is an insulated collection bucket, and the feeding component 52 is a push-pull cylinder 223.

[0062] When using the welding apparatus of this application, firstly, the mounting mechanism 12 is in the feeding position. The blade substrate 6 in the first vibratory feeder 211 moves to below the feeding assembly 22 via the first connecting rail 212 and the blade substrate conveyor belt 23. Then, the feeding assembly 22 moves the blade substrate 6 to the support part 1231. Next, the rotary drive 11 is activated, causing the mounting mechanism 12 to move to the coating position. At this time, the contact part 1232 and the mounting part 122 respectively abut against the blade substrate 6. Then, the coating module 3 sequentially applies flux and brazing filler metal to the groove 1222 of the blade substrate 6. After coating is completed, the rotary drive 11 is activated, causing the mounting mechanism 12 to move to the welding position. Then, the conveying assembly 45 moves, causing the induction heating coil 422 to be sleeved on the blade substrate 6. The blade head feeding conveyor belt 46 contacts the second connecting rail 412. Then, the second vibratory feeder 411 feeds the blade head 7, causing the blade head 7 to... The cutting head 7 is moved onto the cutting head feeding conveyor belt 46. When the cutting head 7 moves to a position corresponding to the blade base 6, the cutting head feeding conveyor belt 46 and the second vibrating plate 411 stop. The translation drive mechanism 431 drives the push block 432 to move. The push block 432 pushes the cutting head 7 on the cutting head feeding conveyor belt 46 above the abutment part 1232 into the groove 1222 of the blade base 6. The pressure drive mechanism 49 drives the pressure member 48 to move, so that the pressure member 48 presses against the cutting head 7. Then the power supply 421 works, so that the induction heating coil 422 heats the cutting head 7 and the blade base 6. After heating for a period of time, the welding is completed, and the conveying assembly 45 drives the induction heating coil 422 and the cutting head feeding conveyor belt 46 to move out. Then the rotary drive 11 is activated, causing the mounting mechanism 12 to move to the unloading position. At this time, the abutment part 1232 and the mounting part 122 no longer hold the blade. Then the unloading assembly 52 pushes the blade, causing the blade to fall into the receiving assembly 51, thereby completing a welding process.
