Description

Technical Field

[0001] The present invention relates to the technical field of tool processing, in particular to a welding processing device for producing tools. Background Art

[0002] CNC cutting tools, also known as cutting tools, are tools used for cutting in mechanical manufacturing. They are primarily used in CNC milling machines, CNC lathes, and other CNC equipment. To meet the various non-standard machining requirements of mechanical manufacturing, CNC cutting tools for CNC lathes typically weld a superhard alloy tip to a standard metal shank, creating a tool that can be used to machine parts.

[0003] For example, a machining tool for CNC tool welding with announcement number CN216065907U fixes the tool to a fixed seat by means of a pressing structure and a clamping mechanism provided on a base plate. The pressing structure and the clamping mechanism can restrict the tool head portion to the head of the tool, preventing the flux between the tool and the tool head from melting when the electromagnetic heating ring heats the tool head, thereby causing the tool head and the tool to become misaligned. However, in actual use, when brazing the handle and the tool head of the CNC tool, the brazing material melts and fills the space between the handle and the tool head during the brazing process, and the handle and the tool head are fixed by the brazing material. After the welding is completed, the tool needs to clean the excess brazing material at the weld. The operator uses a handheld steel brush or file to clean the weld, which is inefficient and inconvenient to fully clean the weld. In addition, the temperature of the tool is too high at this time, which has the disadvantage of easily causing burns to the operator during the cleaning process.

[0004] Therefore, we have proposed a welding processing device for tool making to solve the above-mentioned problems. Summary of the Invention

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows: for the welding processing device used for manufacturing the tool, when welding the tool, it is convenient to clean the filler metal from the weld after welding. During the cleaning process, it can be applied to tools with different specifications and shapes, with strong applicability. When cleaning the welds of tools with different specifications and shapes, it can ensure that the cleaning structure is in close contact with the weld. At the same time, it can avoid excessive cleaning force on the weld and prevent tool damage caused by over-cleaning. Before cleaning the tool, the cleaning position can be adjusted, and the oxides on the end face of the tool handle can be quickly cleaned. After the welding end face of the tool handle, it can be quickly docked with the welding end face of the tool bit, avoiding secondary oxidation of the end face of the tool handle after grinding due to the high-temperature environment during continuous welding work.

[0030] 1. When welding a tool, the tool shank and the tool tip are fixed separately so that the tool tip is butt - jointed with the tool shank. Then, the connection between the tool tip and the tool shank is heated by an electromagnetic heating coil. After that, the filler metal can be covered on the connection of the tool, and brazing can be performed on the tool shank and the tool tip. After the welding is completed, the connection between the tool shank and the tool tip is moved down to the lower part of the steel bristles. Then, the movable plate is moved down so that the steel bristles are in contact with the connection between the tool shank and the tool tip. The top surface of the tool is perpendicular to the steel bristles. Then, the movable plate continues to move down. At this time, the steel bristles are in contact with the tool and no longer move. The downward movement of the movable plate can make the upright frame slide on the moving plate. Through the meshing of the rack and the rotating gear, the rotating shaft can be driven to rotate counterclockwise. When the rotating shaft rotates, the torsion spring is deformed. The reaction force is applied to the steel bristles through the deformation of the torsion spring. During the rotation of the rotating shaft, the rotating block on the column block rotates in a circle, so that the rotating block abuts against one side of the mounting block. Then, the tool can be rotated. During the rotation of the tool, since the cross - section is not circular, the rotation range of the tool changes continuously. When the rotation range of the tool becomes larger, the cleaning plate can be pushed up. At this time, through the meshing of the rack and the rotating gear, the rotating shaft is driven to rotate. After the rotating shaft rotates, the bidirectional lead screw can be driven to rotate through the abutment of the rotating block and one side of the mounting block. After the bidirectional lead screw rotates, the two vertical plates move closer to each other (the spiral direction on the bidirectional lead screw is only for illustration). After the two vertical plates move closer, the moving plate can be pulled up through the connecting rod. Thus, when the rotation range of the tool increases during rotation, the moving plate can be lifted upward, avoiding excessive reaction force of the steel bristles on the tool and preventing excessive cleaning of the tool. This makes it convenient to clean the filler metal on the weld after tool welding when welding a tool. During the cleaning process, it can be applied to tools of different specifications and shapes, with strong applicability. And when cleaning the welds of tools with different specifications and shapes, it can ensure that the cleaning structure is in close contact with the weld, and at the same time, it can avoid excessive cleaning force on the weld, preventing tool damage caused by over - cleaning;

[0031] 2. When welding the tool shank and the tool tip, after fixing the tool shank, start the electric push rod to drive the U-shaped frame to move downward, so that the movable plate moves downward. During the downward movement of the movable plate, the column rod slides in the guide groove. When the movable plate drives the column rod to descend to a certain height, the column rod moves to the inclined section of the guide groove. At this time, the movable plate moves downward and rotates under the action of the guide groove and the column rod, so that the connecting frame rotates on the U-shaped frame, and the bristles on the cleaning plate are inclined. At this time, the tool shank can be controlled to move so that the connecting end face of the tool shank fits with the steel bristles. Then, rotate the tool shank so that the oxide layer on the connecting end of the tool shank can be cleaned. Since the tool shank is made of ordinary metal material, an oxide layer is likely to be generated on the surface. After cleaning, drive the movable plate to move upward by the electric push rod, so that the steel bristles can be lifted, and the oxides on the end face of the tool shank can be quickly cleaned. After that, the welding end face of the tool shank can be quickly butted with the welding end face of the tool tip, avoiding secondary oxidation of the end face of the tool shank after grinding due to the high-temperature environment during continuous welding work;

[0032] 3. When fixing the tool shank, the tool shank can be placed on the positioning seat, and then rotate the bidirectional screw rod to drive the two positioning plates to approach each other to clamp and fix the tool. After that, when the tool shank needs to be moved after being fixed, rotate the hand wheel to drive the screw rod to rotate, so that the movable seat can be driven to move. After the movable seat moves, the fixed plate is driven to move, so that the fixed tool shank can be driven to move. And when it is necessary to control the rotation of the tool shank, start the servo motor to drive the tool shank to rotate, and the rotation speed will not be too fast. When fixing the tool tip, the tool tip can be placed between the two clamping plates, and then rotate the bidirectional threaded rod to control the two clamping plates to approach each other, so that the tool tip can be clamped and fixed. Then, the threaded rod can be rotated to drive the connecting seat to move, which is convenient to control the movement of the tool tip, and thus it is convenient to fix the tool shank and the tool tip and also convenient to move the tool tip and the tool shank.

[0047] The fixing frame 201 is fixedly installed on the top of the workbench 1 and on one side of the electromagnetic heating coil 102.

[0048] The limiting block 206 is fixedly installed on the top of the sliding rod 205. The lower surface of the limiting block 206 abuts against the moving plate 204. Steel bristles 208 are arranged at the bottom of the cleaning plate 207. Mounting frames 209 are symmetrically installed on the top of the moving plate 204;

[0049] Rotating shafts 210 are rotatably connected above the two mounting frames 209. Rotating gears 211 are fixedly installed on the outside of the rotating shafts 210 and on one side of the mounting frames 209. Upright frames 212 are slidably connected inside the moving plate 204 and on one side of the two mounting frames 209. The bottom ends of the upright frames 212 are fixedly connected with the cleaning plate 207. A rack 213 is fixedly installed above one side of the upright frames 212. The rack 213 is meshed and connected with the rotating gear 211;

[0050] A torsion spring 214 is sleeved on the outside of the rotating shaft 210 and on the other side of the mounting frame 209. One end of the torsion spring 214 is fixedly connected with the mounting frame 209. The other end of the torsion spring 214 is fixedly installed with a fixing block 215. The fixing block 215 is fixedly connected with the rotating shaft 210;

[0051] A positioning frame 216 is fixedly installed at the center of the top of the moving plate 204. A bidirectional lead screw 217 is rotatably connected above the positioning frame 216. The outside of the bidirectional lead screw 217 is symmetrically threadedly connected with upright plates 219. The lower parts inside the two upright plates 219 are slidably connected with limiting rods 218. The two ends of the two limiting rods 218 are respectively fixedly connected with the positioning frame 216 and the two mounting frames 209. Connecting rods 220 are hinged at the tops of the two upright plates 219. The ends of the connecting rods 220 far away from the upright plates 219 are hinged with the activity plate 202;

[0052] At one end of the two rotating shafts 210 close to the bidirectional lead screw 217, column blocks 221 are fixedly installed. Rotating blocks 222 are symmetrically installed on the outside of the column blocks 221. An arc-shaped frame 223 is slidably connected inside the rotating blocks 222. At both ends of the arc-shaped frame 223, mounting blocks 224 are fixedly installed. Moreover, the mounting blocks 224 are fixedly connected to the bidirectional lead screw 217.

[0053] Embodiment 1: As Figures 1-5 shown, when welding the tool, the tool handle and the tool tip are fixed respectively to make the tool tip and the tool handle butt-joint. Then, the electromagnetic heating coil 102 is used to heat the connection part of the tool tip and the tool handle. After that, the filler metal can be covered on the connection part of the tool to braze the tool handle and the tool tip. After the welding is completed, the connection part of the tool handle and the tool tip is moved downward to the lower part of the steel bristles 208. Then, the movable plate 202 is moved downward to make the steel bristles 208 fit with the connection part of the tool handle and the tool tip. The top surface of the tool is perpendicular to the steel bristles 208. Then, the movable plate 202 is continuously moved downward. At this time, the steel bristles 208 are in contact with the tool and no longer move. The downward movement of the movable plate 202 can make the vertical frame 212 slide on the moving plate 204. Through the engagement of the rack 213 and the rotating gear 211, the rotating shaft 210 can be driven to rotate counterclockwise. When the rotating shaft 210 rotates, the torsion spring 214 is deformed. The reaction force is applied to the steel bristles 208 through the deformation of the torsion spring 214. During the rotation of the rotating shaft 210, the rotating block 222 on the column block 221 rotates in a circle, making the rotating block 222 abut against one side mounting block 224. Then, the tool can be rotated. During the rotation of the tool, since the cross-section is not circular, the rotation range of the tool changes continuously during the rotation process. When the rotation range of the tool becomes larger, the cleaning plate 207 can be pushed upward. At this time, through the engagement of the rack 213 and the rotating gear 211, the rotating shaft 210 is driven to rotate. After the rotating shaft 210 rotates, the bidirectional lead screw 217 can be driven to rotate through the abutment of the rotating block 222 and one side mounting block 224. After the bidirectional lead screw 217 rotates, the two vertical plates 219 approach each other. After the two vertical plates 219 approach each other, the moving plate 204 can be pulled upward through the connecting rod 220. Therefore, when the rotation range of the tool increases during the rotation process, the moving plate 204 can be lifted upward to avoid excessive reaction force of the steel bristles 208 on the tool and avoid excessive cleaning of the tool. When welding the tool, it is convenient to clean the filler metal on the weld after welding the tool. During the cleaning process, it is applicable to tools of different specifications and shapes, with strong applicability. When cleaning the welds of tools of different specifications and shapes, it can ensure that the cleaning structure is in close contact with the weld, and at the same time, it can avoid excessive cleaning force on the weld and avoid tool damage caused by excessive cleaning.

[0054] An electric push rod 225 is fixedly installed at the top of the fixing frame 201. The movable end of the electric push rod 225 passes through the fixing frame 201 and is fixedly installed with a U-shaped frame 226. Guide rods 227 are symmetrically installed at the top of the U-shaped frame 226. Both of the two guide rods 227 are slidably connected to the fixing frame 201. A connecting frame 228 is hinged inside the U-shaped frame 226. The connecting frame 228 is fixedly connected to the movable plate 202. Column rods 229 are symmetrically installed on both sides of the movable plate 202. Guide grooves 230 are symmetrically formed above the inner side of the fixing frame 201. The column rods 229 are slidably connected to the guide grooves 230.

[0055] Embodiment 2: As Figures 1-2 and Figure 6 shown, when welding the tool handle and the tool tip, after fixing the tool handle, start the electric push rod 225 to drive the U-shaped frame 226 to move downward, so that the movable plate 202 moves downward. During the downward movement of the movable plate 202, the column rod 229 slides in the guide groove 230. When the movable plate 202 drives the column rod 229 to descend to a certain height, the column rod 229 moves to the inclined section of the guide groove 230. At this time, the movable plate 202 moves downward and rotates under the action of the guide groove 230 and the column rod 229, so that the connecting frame 228 rotates on the U-shaped frame 226, and the bristles on the cleaning plate 207 are inclined. At this time, the movement of the tool handle can be controlled so that the connecting end face of the tool handle fits with the steel bristles 208. Then the tool handle is rotated so that the oxide layer on the connecting end of the tool handle can be cleaned. Since the tool handle is made of ordinary metal material, an oxide layer is easily generated on the surface. After cleaning, the electric push rod 225 drives the movable plate 202 to move upward, so that the steel bristles 208 can be lifted, and the oxides on the end face of the tool handle can be quickly cleaned. After that, the welding end face of the tool handle can be quickly butted with the welding end face of the tool tip, avoiding secondary oxidation of the end face of the tool handle after grinding due to the high-temperature environment during continuous welding work.

[0061] Embodiment 3: As Figure 1 and Figures 7-9As shown, when fixing the tool handle, the tool handle can be placed on the positioning seat 309. Then, rotate the bidirectional screw 311 to drive the two positioning plates 312 to move closer to clamp and fix the tool. After fixing the tool handle, when it is necessary to move the tool handle, rotate the handwheel to drive the screw 302 to rotate, so that the movable seat 303 can be driven to move. After the movable seat 303 moves, it drives the fixed plate 304 to move, so that the fixed tool handle can be driven to move. And when it is necessary to control the rotation of the tool handle, the servo motor 305 can be started to drive the tool handle to rotate, and the rotation speed will not be too fast. When fixing the tool tip, the tool tip can be placed between the two clamping plates 406. Then, rotate the bidirectional threaded rod 405 to control the two clamping plates 406 to move closer to each other, so that the tool tip can be clamped and fixed. Then, the threaded rod 402 can be rotated to drive the connecting seat 403 to move, which is convenient for controlling the movement of the tool tip. Furthermore, it is convenient to fix the tool handle and the tool tip and also convenient to move the tool tip and the tool handle.

[0062] Working principle: When using this welding processing device for tool production, first, according to Figures 1-9When welding the tool, the tool handle and the tool tip are fixed respectively so that the tool tip and the tool handle are butted. Then, the electromagnetic heating coil 102 is used to heat the connection between the tool tip and the tool handle. After that, the filler metal can be covered on the connection of the tool, and brazing can be performed on the tool handle and the tool tip. After the welding is completed, the connection between the tool handle and the tool tip is moved downward to the lower part of the steel brush 208. Then, the movable plate 202 is moved downward so that the steel brush 208 fits with the connection between the tool handle and the tool tip. The top surface of the tool is perpendicular to the steel brush 208. Then, the movable plate 202 continues to move downward. At this time, the steel brush 208 abuts against the tool and stops moving. The downward movement of the movable plate 202 can make the vertical frame 212 slide on the moving plate 204. The meshing of the rack 213 and the rotating gear 211 can drive the rotating shaft 210 to rotate counterclockwise. When the rotating shaft 210 rotates, it drives the torsion spring 214 to deform. The deformation of the torsion spring 214 exerts a reaction force on the steel brush 208. During the rotation of the rotating shaft 210, the rotating block 222 on the column block 221 rotates in a circle, so that the rotating block 222 abuts against one side mounting block 224. Then, the tool can be rotated. During the rotation of the tool, since the cross-section is not circular, the rotation range of the tool changes continuously. When the rotation range of the tool becomes larger, the cleaning plate 207 can be pushed upward. At this time, the meshing of the rack 213 and the rotating gear 211 drives the rotating shaft 210 to rotate. After the rotating shaft 210 rotates, the meshing of the rotating block 222 and one side mounting block 224 can drive the bidirectional lead screw 217 to rotate. After the bidirectional lead screw 217 rotates, it drives the two vertical plates 219 to approach each other. After the two vertical plates 219 approach each other, the moving plate 204 can be pulled upward through the connecting rod 220. Therefore, when the rotation range of the tool increases during the rotation of the tool, the moving plate 204 can be lifted upward to avoid excessive reaction force of the steel brush 208 on the tool and prevent excessive cleaning of the tool, so that when welding the tool;

[0063] When welding the tool handle and the tool tip, after fixing the tool handle, start the electric push rod 225 to drive the U-shaped frame 226 to move downward, so that the movable plate 202 moves downward. During the downward movement of the movable plate 202, the column rod 229 slides in the guide groove 230. When the movable plate 202 drives the column rod 229 to descend to a certain height, the column rod 229 moves to the inclined section of the guide groove 230. At this time, when the movable plate 202 moves downward, under the action of the guide groove 230 and the column rod 229, the movable plate 202 rotates, so that the connecting frame 228 rotates on the U-shaped frame 226, and the bristles on the cleaning plate 207 are inclined. At this time, the movement of the tool handle can be controlled to make the connecting end face of the tool handle fit with the steel bristles 208. Then, rotate the tool handle so that the oxide layer on the connecting end of the tool handle can be cleaned. Since the tool handle is made of ordinary metal materials, an oxide layer is likely to be generated on the surface. After cleaning, drive the movable plate 202 to move upward by the electric push rod 225, so that the steel bristles 208 can be lifted. When fixing the tool handle, the tool handle can be placed on the positioning seat 309, and then rotate the bidirectional screw rod 311 to drive the two positioning plates 312 to approach each other to clamp and fix the tool. Then, when the tool handle needs to be moved after being fixed, rotate the hand wheel to drive the screw rod 302 to rotate, so that the movable seat 303 can be driven to move. After the movable seat 303 moves, the fixed plate 304 is driven to move, so that the fixed tool handle can be driven to move. And when the rotation of the tool handle needs to be controlled, the servo motor 305 can be started to drive the tool handle to rotate, and the rotation speed will not be too fast. When fixing the tool tip, the tool tip can be placed between the two clamping plates 406, and then rotate the bidirectional threaded rod 405 to control the two clamping plates 406 to approach each other, so that the tool tip can be clamped and fixed. Then, the threaded rod 402 can be rotated to drive the connecting seat 403 to move.
