Description

Technical Field

[0001] This utility model belongs to the field of welding equipment technology, specifically a tungsten electrode welding head grinding machine. Background Technology

[0002] In the field of welding technology, tungsten inert gas (TIG) welding tips are key components, and their surface quality and tip shape significantly impact welding results. To ensure welding stability and quality, precise grinding of the TIG welding tip is necessary, including face smoothing and tip angle adjustment. However, existing TIG welding tip grinding equipment is generally limited in function, typically only capable of single face smoothing or tip sharpening operations. It cannot achieve efficient, continuous multi-process processing on a single machine, resulting in low production efficiency. Furthermore, existing equipment struggles to precisely control the angle between the grinding wheel and the welding tip during tip sharpening, especially under complex angle requirements, easily leading to low grinding accuracy and poor consistency. Simultaneously, traditional equipment lacks rotary grinding capabilities, preventing omnidirectional circular grinding of the welding tip, further limiting improvements in processing quality and efficiency. Therefore, developing a TIG welding tip grinding machine that integrates face smoothing and tip sharpening functions, along with angle adjustment and rotary grinding capabilities, to meet the demands of high-precision and high-efficiency processing has become an urgent technical challenge. Utility Model Content

[0003] This invention addresses the problems of low processing efficiency, insufficient precision, and inability to meet various sharpness requirements in existing tungsten electrode welding head grinding equipment by proposing a tungsten electrode welding head grinding machine. The equipment integrates a flattening mechanism and a sharpening mechanism, combined with the synergistic effect of an angle adjustment mechanism and a rotation mechanism, to achieve efficient and precise flattening and sharpening of the tungsten electrode welding head tip.

[0004] This utility model provides a tungsten electrode welding head grinding machine, including a machine housing base, a grinding flattening mechanism, and a grinding tipping mechanism. Both the grinding flattening mechanism and the grinding tipping mechanism are located at the upper end of the machine housing base. The grinding tipping mechanism further includes a grinding mechanism, an angle adjustment mechanism, and a rotating mechanism. The rotating mechanism is fixed to the machine housing base, and the grinding mechanism is connected to the upper end of the rotating mechanism via the angle adjustment mechanism. Specifically, the grinding flattening mechanism is used to perform preliminary flattening of the tungsten electrode welding head end, while the grinding tipping mechanism, through a combination of angle adjustment and rotational movement, completes the precise grinding tipping of the tungsten electrode welding head end.

[0005] Furthermore, the grinding mechanism includes a grinding drive motor and a grinding wheel. The lower end of the grinding drive motor is fixedly connected to the upper end of the equipment housing base, and its driving end extends upward and is fixedly connected to the grinding wheel. Driven by the grinding drive motor, the grinding wheel rotates at high speed, performing contact grinding on the end of the tungsten electrode welding head to remove uneven surfaces. The rotation direction of the grinding wheel is perpendicular to the feed direction of the tungsten electrode welding head to ensure uniformity during the grinding process.

[0006] Specifically, the rotating mechanism includes a grinding mechanism support, a support rotation drive gear, a support rotation connecting shaft, a support rotation drive gear, and a support rotation drive motor. The lower end of the grinding mechanism support is fixedly connected to the upper end of the support rotation drive gear, and the middle part of the support rotation drive gear is rotatably connected to the upper end of the equipment housing base via the support rotation connecting shaft. The support rotation drive motor is fixed to the equipment housing base, and its drive end is fixedly connected to the support rotation drive gear, which meshes with the support rotation drive gear. The operation of the support rotation drive motor drives the support rotation drive gear to rotate, which in turn drives the support rotation drive gear to rotate around the support rotation connecting shaft, enabling the grinding mechanism support to achieve circular motion.

[0007] Furthermore, the grinding mechanism includes a grinding tip motor frame, a grinding tip grinding wheel, and a grinding tip drive motor. The upper two sides of the grinding tip motor frame are connected to the upper two sides of the grinding tip mechanism support via rotating joints, and its lower end is connected to the grinding tip mechanism support via an angle adjustment mechanism. The grinding tip drive motor is fixed to the grinding tip motor frame, and its rotating shaft is fixedly connected to the grinding tip grinding wheel for driving the grinding tip grinding wheel to rotate. The grinding tip grinding wheel is located in the middle of the grinding tip motor frame, corresponding to the tungsten electrode welding head insertion hole, and is used for contact grinding of the tungsten electrode welding head.

[0008] The angle adjustment mechanism includes a grinding tip motor frame angle adjustment rack, a grinding tip angle adjustment motor, and a grinding tip angle adjustment gear. The grinding tip motor frame angle adjustment rack has an arc-shaped structure, with one side fixedly connected to one side of the grinding tip motor frame. The grinding tip angle adjustment motor is fixed to the grinding tip mechanism support, and its shaft is fixedly connected to the grinding tip angle adjustment gear. The grinding tip angle adjustment gear meshes with the grinding tip motor frame angle adjustment rack. The operation of the grinding tip angle adjustment motor drives the grinding tip angle adjustment gear to rotate, which in turn moves the grinding tip motor frame angle adjustment rack along an arc-shaped trajectory, thus achieving angle adjustment of the grinding tip motor frame.

[0009] Specifically, the upper end of the grinding mechanism support is provided with a tungsten electrode insertion hole, which is located above the grinding wheel. The inner diameter of the tungsten electrode insertion hole matches the outer diameter of the tungsten electrode, ensuring that the tungsten electrode maintains a stable positioning state during insertion. The positional design of the tungsten electrode insertion hole allows the tungsten electrode to form a precise contact angle with the grinding wheel after insertion, thereby achieving high-precision control of the grinding process.

[0010] The application process of this utility model is divided into two stages: S1. Grinding stage; S2. Sharpening stage. In S1, the end of the tungsten electrode welding head is moved downwards facing the grinding wheel, and the grinding wheel is rotated using a grinding drive motor to perform preliminary grinding of the end of the tungsten electrode welding head. In S2, the tungsten electrode welding head is inserted into the tungsten electrode welding head insertion hole and gradually moved downwards until it contacts the sharpening grinding wheel. The sharpening drive motor is started, driving the sharpening grinding wheel to rotate and sharpen the tungsten electrode welding head. The sharpening angle adjustment motor drives the sharpening angle adjustment gear to rotate, which in turn drives the angle adjustment rack of the sharpening motor frame to move, causing the lower end of the sharpening motor frame to swing and the upper end to rotate, thereby adjusting the angle of the sharpening grinding wheel to achieve the required sharpness. Simultaneously, during the sharpening process, the support rotation drive motor is started, driving the support rotation drive gear to rotate, which in turn drives the support rotation drive gear to rotate. The support rotates and drives the toothed disc to rotate under the action of the support rotating connecting shaft, which drives the support of the grinding mechanism to rotate, so that the grinding wheel and grinding disc can perform a circular grinding around the tungsten electrode welding head to achieve uniform grinding.

[0011] The beneficial effects of this utility model are:

[0012] First, the coordinated operation of the flattening and sharpening mechanisms significantly improves the processing efficiency of tungsten inert gas (TIG) welding heads. Second, the angle adjustment mechanism, through gear and rack transmission, enables precise adjustment of the grinding wheel angle, meeting the processing requirements for different sharpnesses. Third, the design of the rotating mechanism ensures that the grinding wheel evenly covers the surface of the TIG welding head during its circular motion, avoiding quality problems caused by localized over-grinding. Finally, the equipment has a compact overall structure and is easy to operate, suitable for various specifications and types of TIG welding heads, exhibiting wide applicability and practicality.

[0013] In summary, this utility model, through specific structural design and technical means, solves the problems of low processing efficiency, insufficient precision, and poor adaptability in the prior art, and provides an efficient and reliable solution for pre-welding preparation work.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0022] This utility model provides a tungsten inert gas welding head grinding machine. The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Figures 1 to 5 The diagrams show the internal and external structures of this utility model, with each component identified by Arabic numerals. These numerals correspond to the markings in the accompanying drawings, facilitating a clear understanding of the overall structure and operating principle of the device.

[0023] like Figure 1 and Figure 3 As shown, the tungsten electrode welding head grinding machine of this utility model includes an equipment housing base 1, a grinding flattening mechanism, and a grinding tip mechanism. The equipment housing base 1 serves as the fundamental support for the entire equipment, with the grinding flattening mechanism and the grinding tip mechanism mounted on its upper end. The grinding flattening mechanism is used to perform preliminary flattening of the tungsten electrode welding head end, while the grinding tip mechanism is responsible for the precise grinding of the tungsten electrode welding head. The grinding tip mechanism further includes a grinding mechanism, an angle adjustment mechanism, and a rotation mechanism. These mechanisms work together to ensure the efficiency and precision of the grinding process. The layout of the grinding flattening mechanism and the grinding tip mechanism on the equipment housing base 1 is compact and reasonable, saving space and facilitating operation.

[0024] The core components of the grinding mechanism include a grinding drive motor 2 and a grinding wheel 3. The lower end of the grinding drive motor 2 is fixedly connected to the upper end of the equipment housing base 1, and its driving end extends upward and is fixedly connected to the grinding wheel 3. The grinding drive motor 2 drives the grinding wheel 3 to rotate at high speed through its internal electromagnetic torque, thereby achieving contact grinding of the tungsten electrode tip. The outer surface of the grinding wheel 3 is designed with a rough structure, which can effectively remove the uneven parts of the tungsten electrode tip. In practical applications, the rotation direction of the grinding wheel 3 is perpendicular to the feed direction of the tungsten electrode tip. This arrangement ensures the uniformity of the grinding process and avoids material deformation or damage caused by excessive unidirectional force.

[0025] The design of the sharpening mechanism is one of the key innovations of this utility model, and its core lies in the coordinated use of the rotating mechanism and the angle adjustment mechanism. For example... Figure 1 and Figure 3 As shown, the rotating mechanism consists of a grinding mechanism support 4, a support rotation drive gear 12, a support rotation connecting shaft 13, a support rotation drive gear 14, and a support rotation drive motor 15. The lower end of the grinding mechanism support 4 is fixedly connected to the upper end of the support rotation drive gear 12, and the middle part of the support rotation drive gear 12 is rotatably connected to the upper end of the equipment housing base 1 through the support rotation connecting shaft 13. The support rotation drive motor 15 is fixedly mounted on the equipment housing base 1, and its drive end is fixedly connected to the support rotation drive gear 14, which meshes with the support rotation drive gear 12. When the support rotation drive motor 15 starts, its drive end drives the support rotation drive gear 14 to rotate, which in turn drives the support rotation drive gear 12 to rotate around the support rotation connecting shaft 13. This rotational motion causes the grinding mechanism support 4 to achieve a circular motion, thereby driving the grinding mechanism to perform uniform grinding around the tungsten electrode welding head in one revolution.

[0026] The specific structure of the grinding mechanism is as follows: Figure 2 and Figure 4 As shown, the system includes a grinding tip motor frame 5, a grinding tip grinding wheel 6, and a grinding tip drive motor 7. The upper two sides of the grinding tip motor frame 5 are connected to the upper two sides of the grinding tip mechanism support 4 via rotating joints, while its lower end is connected to the grinding tip mechanism support 4 via an angle adjustment mechanism. The grinding tip drive motor 7 is fixedly mounted on the grinding tip motor frame 5, and its rotating shaft is fixedly connected to the grinding tip grinding wheel 6. The grinding tip drive motor 7 drives the grinding tip grinding wheel 6 to rotate at high speed through its internal electromagnetic torque, thereby performing contact grinding on the tungsten inert gas (TIG) welding head. The grinding tip grinding wheel 6 is located in the middle of the grinding tip motor frame 5, corresponding to the TIG welding head insertion hole 8, ensuring that the contact angle between the grinding tip grinding wheel 6 and the TIG welding head is precisely controllable during the grinding process.

[0027] The angle adjustment mechanism allows for precise adjustment of the 6-degree angle of the grinding wheel disc. For example... Figure 2and Figure 4 As shown, the angle adjustment mechanism includes a grinding tip motor frame angle adjustment rack 9, a grinding tip angle adjustment motor 10, and a grinding tip angle adjustment gear 11. The grinding tip motor frame angle adjustment rack 9 has an arc-shaped structure, with one side fixedly connected to one side of the grinding tip motor frame 5. The grinding tip angle adjustment motor 10 is fixedly mounted on the grinding tip mechanism support 4, and its rotating shaft is fixedly connected to the grinding tip angle adjustment gear 11, which meshes with the grinding tip motor frame angle adjustment rack 9. When the grinding tip angle adjustment motor 10 starts, its drive end drives the grinding tip angle adjustment gear 11 to rotate, thereby driving the grinding tip motor frame angle adjustment rack 9 to move along an arc-shaped trajectory. This movement causes the lower end of the grinding tip motor frame 5 to swing, and simultaneously causes the upper end of the grinding tip motor frame 5 to rotate, thereby changing the angle of the grinding tip grinding wheel disc 6. By precisely controlling the operating parameters of the grinding tip angle adjustment motor 10, the angle of the grinding tip grinding wheel disc 6 can be finely adjusted to meet the processing requirements of different sharpnesses.

[0028] like Figure 5 As shown, the upper end of the grinding mechanism support 4 is provided with a tungsten inert gas (TIG) welding head insertion hole 8, which is located above the grinding wheel 6. The inner diameter of the TIG welding head insertion hole 8 matches the outer diameter of the TIG welding head, ensuring that the TIG welding head maintains a stable positioning state during insertion. In actual operation, after the TIG welding head is fixed by a robotic arm or other clamping device, it is inserted through the TIG welding head insertion hole 8 and gradually moved downwards until it contacts the grinding wheel 6. This design not only improves the convenience of operation but also ensures the stability of the TIG welding head during grinding, avoiding machining errors caused by positional deviation.

[0029] The application process of this utility model is divided into two stages: S1 is the flattening stage, and S2 is the sharpening stage. In S1, the tungsten electrode welding head to be processed is first fixed by a robotic arm or other clamping device, and its end is moved downwards facing the flattening grinding wheel 3. The flattening drive motor 2 is started, and its drive end drives the flattening grinding wheel 3 to rotate at high speed, performing contact grinding on the end of the tungsten electrode welding head to remove the uneven parts of the surface. During the flattening process, the rotation direction of the flattening grinding wheel 3 is perpendicular to the feed direction of the tungsten electrode welding head to ensure the uniformity of the grinding process. After the flattening treatment, the end of the tungsten electrode welding head presents a flat state, laying the foundation for the subsequent sharpening process.

[0030] In step S2, the ground tungsten electrode welding head is inserted into the tungsten electrode welding head insertion hole 8 and gradually moved downwards until it contacts the grinding wheel 6. The grinding tip drive motor 7 is started, and its drive end drives the grinding wheel 6 to rotate at high speed, performing contact grinding on the tungsten electrode welding head. During the grinding process, the grinding tip angle adjustment motor 10 is started according to actual needs, driving the grinding tip angle adjustment gear 11 to rotate, which in turn drives the grinding tip motor frame angle adjustment rack 9 to move along an arc trajectory. This movement causes the lower end of the grinding tip motor frame 5 to swing, while the upper end rotates, thereby changing the angle of the grinding wheel 6. By precisely controlling the operating parameters of the grinding tip angle adjustment motor 10, the angle of the grinding wheel 6 can be finely adjusted to meet the processing requirements of different sharpnesses. In addition, during the grinding process, the support rotation drive motor 15 is started, driving the support rotation drive gear 14 to rotate, which in turn drives the support rotation drive gear 12 to rotate around the support rotation connecting shaft 13. This rotational motion causes the grinding tip support 4 to move in a circular motion, thereby driving the grinding wheel 6 to perform uniform grinding around the tungsten electrode welding head in one revolution. The coordinated action of the rotation mechanism and the angle adjustment mechanism ensures the high efficiency and precision of the grinding process.

[0031] In practical applications, the tungsten inert gas (TIG) welding head grinding machine of this invention is suitable for processing various specifications and types of TIG welding heads. For example, in the pre-welding preparation stage, operators can select appropriate grinding parameters according to the welding process requirements, including grinding speed, angle adjustment range, and rotation speed. Through precise control of these parameters, efficient and accurate grinding of the TIG welding head tip can be achieved, significantly improving welding quality. Furthermore, the equipment of this invention has a compact structure and is easy to operate, facilitating integration into industrial production lines and possessing wide applicability and practicality.

[0032] In summary, this utility model, through specific structural design and technical means, solves the problems of low processing efficiency, insufficient precision, and poor adaptability in the prior art, and provides an efficient and reliable solution for pre-welding preparation work.
