Description

Technical Field

[0001] The invention relates to the technical field of tool processing, and in particular to a tool production device for numerical control processing. Background Art

[0002] The tools that usually need to be welded in CNC machine tools are those that use a combination of carbide (such as tungsten steel) blades and steel tool holders. The welding process is mainly used to connect the carbide blades and tool holders together to form a complete cutting tool.

[0003] In the prior art, vacuum brazing of cutting tools is usually performed manually. Solder paste must be applied to the position on the cutting tool where welding is required. After applying the solder paste, the blade is placed at the welding position, and then the tray is sent to the oven for drying. The purpose of this operation is to evaporate moisture for fixation to prevent the workpiece from shifting during subsequent welding in the vacuum brazing furnace. Then the workpieces in the tray are placed one by one in the vacuum brazing furnace, and the workpieces must be separated when placed. After the processing is completed, the workpieces are clamped into the tray one by one. The problems in this process are: First, the process of splicing the workpieces relies on manual tweezers to place them. Since the workpieces are small, the operator's proficiency and vision are required to be high. When placing the workpieces, it is necessary to pay attention to whether the tool rod and the blade are aligned. If they are offset, the yield of the finished product will be affected. Second, solder paste needs to be added when splicing and placing between the tool rod and the blade. A small amount of solder paste needs to be picked up by a tool and placed between the workpieces. However, the amount of solder paste is not easy to control. Too much or too little will affect subsequent processing. Therefore, the present application provides a CNC tool production device to meet the needs. Summary of the invention

[0016] By arranging the pushing mechanism, the extrusion rod can be driven to move in the process of pushing the mounting plate, so that the solder paste falls on the notch on the knife rod through the paste outlet tube.

[0017] By setting an extrusion component, when the extrusion rod drives the extrusion block to extrude the solder paste, the protrusion on the surface of the extrusion block can extend into the solder paste, which can play a role in splitting the viscous paste, which is beneficial to pushing the paste; and when the protrusion is squeezed to the bottom in the solder paste shell, the protrusion is squeezed inward, which is beneficial to the contact between the extrusion block and the inner end of the solder paste shell, reducing the residual paste in the shell.

[0047] like Figures 1 to 17As shown, an embodiment of the present invention provides a tool production device for CNC machining, including a main housing 1 and a mounting plate 3, wherein a through slot 2 is provided in the main housing 1 for the mounting plate 3 to pass through, a tool bar slot 12 and a blade slot 13 are provided on the main housing 1, a tool bar 8 and a blade 10 are stacked in the tool bar slot 12 and the blade slot 13 respectively, a notch 9 corresponding to the size of the blade 10 is provided on the surface of the tool bar 8, the tool bar 8 and the blade 10 are spliced ​​into a complete workpiece when the mounting plate 3 passes through the through slot 2, and the complete workpiece is located in a placement slot 5 provided on the surface of the mounting plate 3, and first racks 4 are fixedly connected to both sides of the mounting plate 3; a pair of tool bars 12 and blade slots are provided in the main housing 1, respectively, and a notch 9 corresponding to the size of the blade 10 is provided on the surface of the tool bar 8. 13 is connected to the guide groove 15, and the guide groove 15 passes through the through groove 2; it also includes a pushing mechanism 16, which is used to fill solder paste between the knife rod 8 and the blade 10, and the pushing mechanism 16 is connected to the main shell 1; when the mounting plate 3 is moved, the mounting plate 3 passes under the guide groove 15, and the knife rod 8 or the blade 10 stacked in the guide groove 15 slides on the surface of the mounting plate 3. When the guide groove 15 is located above the placement groove 5, the knife rod 8 or the blade 10 in the guide groove 15 falls into the placement groove 5, and the mounting plate 3 is continued to be moved to achieve the function of placing the knife rod 8 and the blade 10, and the placement groove 5 and the knife rod 8 and the blade 10 are adapted to each other in size to prevent the knife rod 8 and the blade 10 from being offset when they are placed.

[0048] like Figures 3 to 5 As shown, the pushing mechanism 16 includes a fixing groove 17 opened on the main shell 1, and a solder paste shell 18 is inserted and fixed in the fixing groove 17. The solder paste shell 18 is a prior art product. A clamping component 21 is installed at one end of the solder paste shell 18, and a squeezing rod 22 is slidably connected in the clamping component 21. A squeezing component 23 located in the solder paste shell 18 is fixed at one end of the squeezing rod 22, and a detachable bracket 19 is fixed at the other end of the squeezing rod 22. A second rack 20 is fixedly connected to the bottom end of the bracket 19. A paste outlet tube 14 is fixedly connected in the through groove 2, and one end of the paste outlet tube 14 faces above the recess 9. The other end of the paste outlet tube 14 is fixedly connected to a plug that is plugged and matched with the paste outlet end of the solder paste shell 18; flip plates 34 are installed on the opposite side walls in the through groove 2. A gear component 35 is provided on each flip plate 34; since the gear component 35 is located between the second rack 20 and the first rack 4 on the mounting plate 3, the second rack 20 and the first rack 4 can make relative movement. When the mounting plate 3 moves in the through groove 2, the first racks 4 on both sides of the mounting plate 3 drive the gear component 35 to rotate counterclockwise, and the counterclockwise rotating gear component 35 drives the second rack 20 to move inward, so that the extrusion rod 22 on the bracket 19 drives the extrusion component 23 to be squeezed into the solder paste shell 18, so that the solder paste falls on the notch 9 on the knife rod 8 through the paste outlet tube 14; wherein the second rack 20 is a U-shaped structure, and the second racks 20 on both sides of the U-shaped structure and the first racks 4 on both sides of the mounting plate 3 are more stable during transmission.

[0049] like Figures 5 to 8 As shown, the extrusion component 23 includes an integrated extrusion block 24 and a protrusion 25, and the protrusion 25 is a hollow structure, wherein the extrusion block 24 and the protrusion 25 are made of an integrated rubber material. The advantage of such a configuration is that when the extrusion rod 22 drives the extrusion block 24 to squeeze the solder paste, the protrusion 25 on the surface of the extrusion block 24 can extend into the solder paste, which can play a role in splitting the viscous paste, which is beneficial to pushing the paste; and the protrusion 25 is a hollow structure. When the protrusion 25 is squeezed to the bottom in the solder paste shell 18, the protrusion 25 is squeezed inwardly, which is beneficial to the contact between the extrusion block 24 and the inner end of the solder paste shell 18, and is beneficial to reducing the residual paste in the shell.

[0050] like Figure 5 , Figure 6 as well as Fig.11 As shown, the fixing component 21 includes a rubber plug 27 and a fixing cylinder 28, a first annular groove 29 is provided in the rubber plug 27, an annular rod 30 is inserted and fixed in the first annular groove 29, a plurality of support bars 31 are fixedly connected to one end of the annular rod 30, and a plurality of support bars 31 are fixedly connected to one end of the first annular groove 29; the plurality of support bars 31 are arranged in an annular manner, a plurality of second annular grooves 33 are provided on the surface of the extrusion rod 22, the connection between the plurality of second annular grooves 33 is an arc structure, and the plurality of second annular grooves 33 and the plurality of extrusion plates 32 are snap-fitted; the support bars 31, the annular rod 30 and the extrusion plates 32 are an integral elastic structure, the plurality of support bars 31 are expanded outward in a default state, the plurality of extrusion plates 32 on the plurality of support bars 31 are triangular structures, the convex parts on the triangular structures and the extrusion rods The second annular groove 33 on the surface of 22 is snap-fitted; during installation, the rubber plug 27 is plugged into the opening of the solder paste housing 18, and multiple expanded branches 31 are placed in the solder paste housing 18. On the one hand, the multiple expanded branches 31 maintain elastic force to expand outward when inserted into the solder paste housing 18, which is beneficial to improve the fixing strength of the rubber plug 27. On the other hand, when the multiple branches 31 are installed in the solder paste housing 18, the extrusion plates 32 on the multiple branches 31 are all squeezed into the second annular groove 33; the advantage of such a setting is that when the extrusion rod 22 no longer moves, the extrusion plate 32 is stuck in the second annular groove 33, which can prevent the extrusion rod 22 from shifting; in addition, since the connection between the multiple second annular grooves 33 is an arc structure, it is beneficial for the extrusion plate 32 on the extrusion rod 22 to slide between the multiple second annular grooves 33.

[0051] like Fig.14 and Fig.15As shown, the gear component 35 includes at least two gears 36, and a surface where the two gears 36 contact each other is fixedly connected with a plurality of annularly arranged convex strips 39; both surfaces of the main housing 1 are rotatably connected with a flip plate 34, and a fixing rod 38 is fixedly connected to the inner surface of the flip plate 34, and the two gears 36 are sleeved on the fixing rod 38, and a fastening ring 37 is also threadedly fixed on the fixing rod 38; by setting at least two gears 36, and the surfaces where the multiple gears 36 contact each other are provided with convex strips 39, when installing, the convex strips 39 on the two gears 36 are staggered, and after being fixed by the fastening ring 37, the staggered convex strips 39 can play a role in limiting. The function is to prevent the gear 36 from shifting during the transmission process. The fixed angles of the two gears 36 are adjusted according to the needs, so that the number of teeth of the gears can be changed. The gear 36 and the first rack 4 and the second rack 20 are meshed and transmitted to drive the extrusion rod 22 to move. When the transmission is not carried out, the extrusion rod 22 cannot be driven to move. The longer the meshing time, the longer the pushing distance of the extrusion rod 22, and the shorter the meshing time, the shorter the pushing distance of the extrusion rod 22. Therefore, by setting the above-mentioned gear structure with adjustable spacing, the intermittent transmission of the gear 36 and the first rack 4 and the second rack 20 can be adjusted, so that during processing, the extrusion amount of the solder paste can be adjusted by adjusting the transmission interval.

[0052] like Fig.16 As shown, one end of the mounting plate 3 is fixedly connected with an insert block 7, and the other end of the mounting plate 3 is provided with a slot 6 that is adapted to the size of the insert block 7; by respectively arranging the insert block 7 and the slot 6 at both ends of the mounting plate 3, the external mounting plate 3 can play a guiding role when squeezing the mounting plate 3 in the main shell 1, thereby preventing the problem of offset when pushing the mounting plate 3, and facilitating use by operators.

[0053] like Figure 5 and Fig.17 As shown, one end of the second rack 20 close to the bracket 19 is rotatably connected to a rolling drum 26, and the rolling drum 26 is in contact with the surface of the mounting plate 3; a lubricating layer 11 is provided on the surface of the mounting plate 3, and the lubricating layer 11 is a prior art product, which is conducive to the movement of the mounting plate 3 in the through groove 2; an air bag ring 40 is provided on the surface of the rolling drum 26, and a plurality of air holes are opened on the surface of the air bag ring 40. The advantage of such a setting is that after the blade 10 is placed in the recess 9, it will pass under the rolling drum 26, and the rolling drum 26 rolls on the blade 10, which is conducive to improving the contact between the blade 10 and the knife rod 8 and the solder paste; in addition, since the air bag ring 40 is a hollow structure and has air holes on its surface, when the rolling drum 26 rolls, the air bag ring 40 is squeezed and compressed, which can buffer the contact with the blade 10 and the knife rod 8, and when the air bag ring 40 is compressed, the air inside it will spray outward, which is conducive to blowing away the dust on the surface of the blade 10 and the knife rod 8.

[0054] It should be noted that the sizes and quantities of the gears and racks shown in the drawings of this application are for illustration only and do not limit their size specifications and quantities.

[0055] The working principle of the technical solution provided by the present invention is as follows: before use, the mounting plate 3 is first placed in the through groove 2, and then the tool rod 8 and the blade 10 are respectively placed in the corresponding guide groove 15 through the tool rod groove 12 and the blade groove 13 for stacking, and then the mounting plate 3 is pushed, and the mounting plate 3 passes under the guide groove 15, and the tool rod 8 or the blade 10 stacked in the guide groove 15 slides on the surface of the mounting plate 3. When the guide groove 15 is located above the placement groove 5, the tool rod 8 or the blade 10 in the guide groove 15 falls into the placement groove 5.

[0056] Continue to push the mounting plate 3, the first racks 4 on both sides of the mounting plate 3 drive the gear component 35 to rotate counterclockwise, and the counterclockwise rotating gear component 35 drives the second rack 20 to move inward, so that the squeezing rod 22 on the bracket 19 drives the squeezing component 23 to squeeze into the solder paste housing 18, so that the solder paste falls on the notch 9 on the knife rod 8 through the paste outlet tube 14.

[0057] Continue to push the mounting plate 3, and the blade 10 is placed into the notch 9 on the tool rod 8 in the same way as the tool rod 8 described above, so that the installation of the complete workpiece is completed. Finally, the complete workpiece will pass under the rolling cylinder 26, and the rolling cylinder 26 rolls on the blade 10, which can improve the contact between the blade 10 and the tool rod 8 and the solder paste; at the same time, the airbag ring 40 is squeezed and compressed when rolling, which can buffer the contact with the blade 10 and the tool rod 8, and when the airbag ring 40 is compressed, the air inside it will spray outward, which is conducive to blowing away the dust on the surface of the blade 10 and the tool rod 8.

[0058] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0059] The above is only a preferred embodiment of the present invention.
