Abstract
Description
Technical Field
[0001] This utility model relates to the field of automation equipment technology, and in particular to an automatic tool welding system. Background Technology
[0002] In modern manufacturing, bearings are key components of various mechanical equipment, and their quality and performance directly affect the operational stability and service life of the equipment. Bearing rings, as an important part of bearings, have extremely stringent requirements for machining precision and quality. The pipe cutter for the lower bearing ring plays an indispensable role in this production process. It is specifically designed for cutting pipes to accurately obtain bearing ring blanks that meet specific size and shape requirements, laying the foundation for a series of subsequent precision machining processes.
[0003] The blades of these pipe cutters, given the high demands of cutting operations, are typically made of materials with high hardness and high wear resistance; cemented carbide is a typical example. The use of such materials effectively ensures high precision in the cutting process while significantly extending the actual service life of the tool, thereby improving production efficiency and reducing costs. However, precisely because of the special nature of the blade material, the handle and the blade often need to be made of different materials.
[0004] Welding is an essential and crucial process in the production of pipe cutters. The quality of the weld directly affects the performance of the pipe cutter in actual use, such as maintaining cutting accuracy and the durability of the tool. However, there is a significant technological shortcoming in the current production of pipe cutters for bearing under-rings: the lack of automated welding equipment specifically designed for this type of tool. Existing welding methods rely heavily on manual operation, which is not only inefficient but also highly susceptible to human factors, making it difficult to ensure consistent welding quality for every tool. This, to some extent, limits the large-scale, high-quality production of pipe cutters for bearing under-rings and indirectly affects the production efficiency and product quality improvement of the entire bearing manufacturing industry. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides an automatic tool welding system, the specific technical solution of which is as follows:
[0006] An automatic tool welding system includes a welding station and a tool handle supply assembly, a blade supply assembly, a copper material supply assembly, and a flux supply assembly arranged around the welding station. The tool handle supply assembly supplies a tool handle to the welding station. The flux coating assembly coats flux onto the tool handle at the welding station. The copper material supply assembly supplies copper onto the flux-coated tool handle. The blade supply assembly supplies a blade to the welding station and presses it onto the copper material, positioning the blade and the copper material. A high-frequency melting device is also provided next to the welding station, which has a high-frequency coil that melts the joint of the blade, copper material, and tool handle after the blade and copper material are positioned.
[0007] Furthermore, the tool handle supply assembly includes a material storage channel and a tool handle pushing cylinder; the tool handles can be stacked in the material storage channel, and the tool handle pushing cylinder is located at the front end of the material storage channel to push the tool handles in the material storage channel one by one to the welding station.
[0008] Furthermore, the storage channel is also equipped with a top plate that applies a certain pressure to the cutter handle to ensure that there is always a cutter handle available for pushing at the front end of the storage channel.
[0009] Furthermore, the flux supply assembly includes a glue applicator, a glue applicator advance cylinder, and a glue applicator translation cylinder; the glue applicator is mounted on the glue applicator advance cylinder, and the glue applicator advance cylinder is mounted on the glue applicator translation cylinder. The glue applicator advance cylinder can control the glue applicator to approach the tool handle on the welding station, and the glue applicator translation cylinder can move the glue applicator along the surface of the tool handle.
[0010] Furthermore, the copper material supply assembly includes a copper feeding nozzle, a copper material feeding cylinder, and a material coil; the copper material can be fed into the copper feeding nozzle by the material coil, and the copper material feeding cylinder delivers the copper feeding nozzle to the tool handle at the welding station.
[0011] Furthermore, the blade supply assembly includes a vibratory feeder, a traversing mechanism, a blade lifting cylinder, and a blade clamping cylinder.

The traversing slider is driven by the blade traversing cylinder and can move between the vibratory feeder and the welding station. The blade lifting cylinder is mounted on the traversing slider and can control the vertical movement of the blade. The blade clamping cylinder is located at the output end of the blade lifting cylinder and is used to clamp and release the blade. Through the cooperation of the traversing mechanism, the blade lifting cylinder, and the blade clamping cylinder, the blade on the vibratory feeder can be clamped out and sent to the tool holder at the welding station. After reaching the tool holder, the blade lifting cylinder applies a certain pressure to press the blade firmly onto the copper material.
[0012] Furthermore, the welding station includes a first positioning mold and a second positioning mold arranged opposite to each other. Both the first positioning mold and the second positioning mold are equipped with cylinders, and the tool handle can be clamped and positioned between the two.
[0013] Furthermore, a discharge channel is provided below the welding station.

Detailed Implementation
[0019] The embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings and examples. The detailed description of the embodiments and the accompanying drawings are used to illustrate the principles of this disclosure by way of example, but should not be used to limit the scope of this disclosure. This disclosure can be implemented in many different forms and is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
[0020] The automatic welding system for cutting tools of this utility model takes welding station 1 as the core, and the tool handle supply component 2, the blade supply component 3, the copper material supply component 4, the flux supply component 5, and the high-frequency melting device 6 are arranged around it in an orderly manner to complete the automated welding process.
[0021] The tool handle supply assembly 2 is the starting point for the automatic tool welding system, providing a stable supply of tool handles 7 throughout the welding process. This assembly includes a storage channel 201 and a tool handle pushing cylinder 202. The storage channel 201 is the storage area for the tool handles 7, which can be neatly stacked within it. The tool handle pushing cylinder 202 is located at the front end of the storage channel 201 and can push the tool handles 7 one by one and in an orderly manner to the welding station 1 according to a preset program. To ensure continuous production, a top plate 203 is also provided in the storage channel 201. The top plate 203 is driven by a spring or a lead screw, which can tightly stack the tool handles 7 within the storage channel 201. The elasticity of the spring or the precise drive of the lead screw ensures that the top plate 203 can always apply a certain pressure to the tool handles 7, ensuring that there are always tool handles 7 available for pushing at the front end of the storage channel 201. In this way, even as the tool handle 7 is continuously fed to the welding station 1, the continuity of supply can be guaranteed, and production interruption due to material shortage can be avoided.
[0022] The flux supply assembly 5 plays an auxiliary role in the welding process of the automatic tool welding system. It includes a flux applicator 501, a flux applicator advance cylinder 502, and a flux applicator translation cylinder 503. The flux applicator 501 utilizes existing technology and can pneumatically control the pumping of flux. The flux applicator 501 is mounted on the flux applicator advance cylinder 502, which in turn is mounted on the flux applicator translation cylinder 503. The flux applicator advance cylinder 502 controls the flux applicator 501 to approach the tool handle 7 on the welding station 1, while the flux applicator translation cylinder 503 moves the flux applicator 501 along the surface of the tool handle 7. Through the cooperation of these two cylinders, the flux applicator 501 can apply flux to designated locations on the tool handle 7, providing favorable conditions for subsequent welding.
[0023] The copper material supply assembly 4 is responsible for accurately conveying the copper material 9 to the welding station 1. It includes a copper feeding nozzle 401, a copper material feeding cylinder 402, and a material coil 403. The copper material 9 is first fed into the copper feeding nozzle 401 by the material coil 403. Then, the copper material feeding cylinder 402 delivers the copper feeding nozzle 401 to the tool holder 7 at the welding station 1. After the copper material 9 is placed on the tool holder 7, the subsequent blade supply assembly 3 delivers the blade 8 onto the copper material 9 and clamps it in place. At this point, the copper material 9, blade 8, and tool holder 7 are tightly fitted together, preparing for the operation of the high-frequency melting device 6.
[0024] The blade supply assembly 3 comprises a vibratory feeder 301, a transverse mechanism, a blade lifting cylinder 302, and a blade clamping cylinder 303. The vibratory feeder 301 is the initial supply device for the blades 8; it arranges and transports the blades 8 to a designated position in an orderly manner through vibration. The transverse mechanism is located above the welding station 1 and is a crucial link in the blade 8 transport. The transverse mechanism includes a blade transverse cylinder 304 and a transverse slider 305. The transverse slider 305, driven by the blade transverse cylinder 304, can move between the vibratory feeder 301 and the welding station 1. The blade lifting cylinder 302 is mounted on the transverse slider 305 and controls the vertical movement of the blades 8. The blade clamping cylinder 303 is located at the output end of the blade lifting cylinder 302 and is used to clamp and release the blades 8. Through the precise coordination of the transverse mechanism, the blade lifting cylinder 302, and the blade clamping cylinder 303, the blade supply assembly 3 can accurately clamp the blade 8 from the vibrating feeder 301 and deliver it to the tool holder 7 at the welding station 1. Upon reaching the tool holder 7, the blade lifting cylinder 302 applies pressure to press the blade 8 firmly onto the copper material 9, thus positioning the blade 8. In this way, the blade 8, the copper material 9, and the tool holder 7 are tightly joined together, awaiting welding by the high-frequency melting device 6.
[0025] The high-frequency melting device 6 is the core component of the automatic tool welding system. It is responsible for melting the joint of the blade 8, copper material 9, and tool handle 7 to achieve a strong weld. After the blade 8, copper material 9, and tool handle 7 are positioned on the welding station 1, the high-frequency melting device 6 starts working. It generates a high-frequency electromagnetic field, causing the metal at the joint to heat up rapidly and reach a molten state.
[0026] Welding station 1 includes a first positioning mold 101 and a second positioning mold 102 arranged opposite to each other, at least one of which is equipped with a cylinder. The tool handle 7 can be firmly clamped and positioned between the two, ensuring that no displacement occurs during the welding process and guaranteeing the accuracy and quality of the welding. Meanwhile, a discharge channel 103 is provided below welding station 1. After welding is completed, the tool will fall along the discharge channel 103 onto a material frame or conveyor belt, awaiting further processing.
[0027] Finally, it should be noted that the cutting tool welding of this application requires welding the blade 8 at both ends. Therefore, this application is also equipped with a lifting and rotating clamping robotic arm 10, which consists of a rotating cylinder, a lifting cylinder and a clamping cylinder, and can rotate the handle 7 180 degrees to weld the other end.
[0028] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these embodiments will all fall within the protection scope of the claims of this utility model.
