Description

Technical Field

[0001] The present invention relates to the technical field of tool welding equipment, in particular to a diamond tool welding machine. Background Art

[0002] Diamond is a super-hard and wear-resistant material, and diamond tools have the advantages of extremely high hardness and wear resistance, low friction coefficient, high elastic modulus, high thermal conductivity, low thermal expansion coefficient, and low affinity with non-ferrous metals. There are many types of diamond tools with significant performance differences. The structure, preparation method and application field of different types of diamond tools are quite different. In the production process of diamond tools, a diamond tool welding machine is required. The diamond tool welding machine can weld the diamond tool head and the metal tool handle. Common diamond tool welding methods include brazing and laser welding.

[0003] In the process of diamond tool welding, active brazing filler metal is usually used to connect the tool head and the metal tool handle. However, if the positioning of the tool and the substrate is inaccurate, the welding position will deviate, which may cause the cutting edge position of the tool to not meet the design requirements, affecting the cutting performance and processing accuracy of the tool. In addition, when the solder contains gas impurities, or the surrounding air enters the welding area during the welding process, these gases are trapped in the weld to form pores when the solder solidifies. The presence of pores will reduce the effective bearing area of the weld and reduce the welding strength, thereby affecting the performance and reliability of the tool. How to invent a diamond tool welding machine to solve these problems has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

The role of the knock rod is to ensure the stability of the relative position of the cutter head and the cutter handle before welding, which is beneficial to improving the accuracy and consistency of welding and preventing it from offsetting or shaking. At the same time, during the working process, the rotating shaft can drive the positioning fixture and the extrusion plate to rotate synchronously inside the vertical cylinder, so that the extrusion plate squeezes one end of the ejector rod, and makes the knocking rod and the protective head away from the cutter head. The elastic recovery of the reset spring can quickly reset the knocking rod to achieve the knocking of the cutter head, thereby generating a vibration effect. This vibration can destroy the stability of the bubbles inside the solder, prompting the bubbles to rise and discharge, thereby reducing the formation of pores and improving the service life and reliability of the tool.

[0022] The overall equipment processes the tool: when welding the tool, first place the tool handle 5 on the surface of the positioning fixture 4 and fix it by the positioning fixture 4. The positioning fixture 4 is a prior art and can be selected and used according to specific circumstances, so it will not be described in detail. After completing the positioning of the tool handle 5, the cutter head 6 is placed at the connection of the tool handle 5 to complete the preliminary positioning of the tool. Subsequently, the lifting plate 10 can be driven downward by the lifting frame 8, and the cutter head 6 and the tool handle 5 can be further fixed by the clamping assembly 7 to avoid shaking during processing and affecting the welding quality.

[0023] Reference Figure 5-Figure 11 , further; one end of the rotating shaft 11 away from the motor 9 is fixedly connected to the positioning fixture 4, one end of the positioning fixture 4 is connected to the knife handle 5, the upper end of the knife handle 5 is connected to the knife head 6, the outer wall of the positioning fixture 4 is fixedly connected to a number of extrusion plates 41 distributed in a circumferential array, and the extrusion plates 41 are arranged in an arc shape; the knocking assembly 3 also includes a side plate 39, which is provided with two side plates 39. The two side plates 39 are rotationally symmetrical about the central axis of the vertical cylinder 31, and the side wall of the side plate 39 close to the vertical cylinder 31 is fixedly connected to a sliding rod 310 and a push rod 312. The sliding rod 310 is located above the push rod 312, and the sliding rod 310 is slidably connected to the inner wall of the piston cylinder 38; the end of the push rod 312 away from the side plate 39 passes through the side wall of the vertical cylinder 31, and the outer wall of the push rod 312 is sleeved with a return spring 311, and the two ends of the return spring 311 are respectively connected to the side plates The side wall of the plate 39 and the outer wall of the vertical cylinder 31 are fixedly connected, and one end of the top rod 312 can be slidably connected to the side wall of the extrusion plate 41; the upper end of the side plate 39 is fixedly connected to a fixing rod 37, one end of the fixing rod 37 is provided with a mounting groove 371, and the inner wall of the mounting groove 371 is provided with a limiting groove 372, and the inner wall of the mounting groove 371 is slidably connected to a movable rod 36, and one end of the movable rod 36 located inside the limiting groove 372 is fixedly connected to the limiting block 361, and the limiting block 361 is slidably connected to the limiting groove 372; the movable rod 36 is threadedly connected to an adjusting screw 35, one end of the adjusting screw 35 is rotatably connected to the inner wall of the mounting groove 371, and the end of the movable rod 36 located outside the fixed rod 37 is fixedly connected to the knocking rod 34, and the end of the knocking rod 34 away from the movable rod 36 is fixedly connected to the protective head 341.

[0024] The knocking assembly 3 adjusts and supports different types of cutter heads 6: before installing the cutter head 6, the adjusting screw 35 can be rotated, and the threaded connection between the adjusting screw 35 and the movable rod 36, and the limited sliding between the limit block 361 and the limit groove 372 can drive the movable rod 36 to move up and down inside the installation groove 371, so that it can be adjusted according to cutter heads 6 of different heights, and when installing the cutter head 6, a moving pulling force can be applied to the fixed rod 37 to stretch the return spring 311 for a certain distance, and then the cutter head 6 is placed at the connection of the handle 5, and then the external force is removed. The elasticity of the return spring 311 allows the two knocking rods 34 to clamp the cutter head 6, thereby playing a role of auxiliary positioning and support, ensuring the stability of the relative position of the cutter head 6 and the handle 5 before welding, which is conducive to improving the accuracy and consistency of welding. In addition, the protective head 341 can be set to a specific shape, which can better cooperate with the positioning and support of the cutter head 6 to prevent it from offsetting or shaking, and the protective head 341 can be made of metal-based composite materials. By selecting A suitable metal matrix (such as aluminum matrix, titanium matrix, etc.) and the addition of a high-temperature resistant reinforcing phase (such as silicon carbide particles, alumina fibers, etc.) can make the metal matrix composite material have good high-temperature resistance. Under the working conditions where the cutter head 6 generates high temperature, it can maintain structural stability and avoid the deterioration of material properties due to high temperature. The metal matrix itself has good vibration transmission characteristics, so that the vibration can be transmitted quickly and evenly inside the material, providing effective vibration excitation for the tool. In addition, the metal matrix composite material also has high strength and toughness, and can provide reliable mechanical support and protection when clamping the cutter head 6. The tool handle 5 can be made of cemented carbide, steel or other metals. When welding the tool handle 5 and the cutter head 6, a metal layer (such as Ti, Cr, W, etc.) can be pre-plated on the surface of the cutter head 6, and then brazing is performed through the welding head 21 and the brazing material to complete the welding of the diamond tool. The core connecting material for diamond tool welding is an active brazing material (such as Ag-Cu-Ti), which relies on active elements to achieve the bonding between diamond and metal. The vibration of the knocking component 3 on the tool: during the operation of the motor 9, the rotating shaft 11 will be driven to rotate. At this time, the rotating shaft 11 can drive the positioning fixture 4 and the extrusion plate 41 to rotate synchronously inside the vertical cylinder 31. During the rotation of the extrusion plate 41, the arc-shaped surface on one side will squeeze one end of the push rod 312. Through the mutual sliding between the two, the push rod 312 can drive the side plate 39 to gradually move away from the vertical cylinder 31, and at the same time stretch the reset spring 311. At this time, the side plate 39 will drive the upper fixed rod 37 and the movable rod 36 to move synchronously, thereby making the knocking rod 34 and the protective head 341 move away from the cutter head 6. After the extrusion plate 41 and the push rod 312 are separated, the knocking rod 34 can be quickly reset through the setting of the plane of the extrusion plate 41 and the elastic recovery of the reset spring 311, and the cutter head can be aligned with the protective head 341. 6 is struck, thereby generating a vibration effect, and then the vibration is transmitted to the connection between the tool handle 5 and the tool head 6, causing the tool to vibrate slightly during the welding process. This vibration can destroy the stability of the bubbles inside the solder, causing the bubbles to rise and be discharged, thereby reducing the formation of pores. The frequency and amplitude of the vibration can be adjusted by setting the number of extrusion plates 41 and the speed of the motor 9. By continuously maintaining the vibration during the welding process, the gas can be effectively discharged. After the welding is completed, the vibration is stopped and the tool is taken out. In addition, the vibration can alleviate the thermal stress and mechanical stress generated during the welding process to a certain extent. The material in the welding area is subjected to slight plastic deformation through vibration, which releases part of the stress and reduces the degree of stress concentration, which helps to reduce the generation of cracks caused by excessive stress and improve the service life and reliability of the diamond tool.

[0025] Example 2, refer to Figure 5-Figure 6 , further; the striking assembly 3 includes a vertical cylinder 31, the vertical cylinder 31 is sleeved on the outside of the positioning fixture 4 and the rotating shaft 11, the vertical cylinder 31 is fixedly connected to the upper side wall of the processing table 1, and a placement groove 32 is opened at the upper end of the vertical cylinder 31. The electromagnetic heating coil 33 is fixedly connected to the inside of the placement groove 32, and the outer wall of the vertical cylinder 31 is fixedly connected to two piston cylinders 38 distributed in a circumferential array.

[0026] The electromagnetic heating coil 33 heats the tool: When the electromagnetic heating coil 33 is working, electromagnetic heating utilizes the principle of electromagnetic induction. When an alternating current passes through the electromagnetic heating coil 33, an alternating magnetic field is generated. In the metal material at the connection between the shank 5 and the tool head 6 in the magnetic field, an induced electromotive force is generated, thereby forming an induced current (eddy current). Since the shank 5 is made of metal material, it has its own resistance. When the current passes through it, Joule heat is generated, causing the material to heat up rapidly. This heating method does not require the gradual transfer of heat through heat conduction like the traditional heating method, and can make the connection reach the required welding temperature in a short time. Therefore, the electromagnetic heating coil 33 heats the tool head 5 by 100%. The magnetic field generated by the magnetic heating coil 33 can be distributed more evenly around the connection between the heated tool handle 5 and the tool head 6, avoiding local overheating or insufficient heating, making the temperature distribution at the connection more uniform, ensuring the consistency of welding quality, making the welding joint more firm and reliable, greatly improving the heating efficiency, shortening the welding time, and thus improving production efficiency. In addition, the surrounding of the vertical cylinder 31 can reduce the diffusion of heat and concentrate the heat inside the vertical cylinder 31, thereby ensuring the heat utilization effect. In addition, the electromagnetic heating coil 33 can be properly protected to avoid damage from high temperature, spatter, etc. during the welding process.

[0027] It should be noted that the specific models and specifications of the motors and other electrical components need to be selected and determined based on the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0028] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
