Description

Technical Field

[0001] This utility model relates to the technical field of tungsten needle electrode maintenance tools, and in particular to an auxiliary grinding device for tungsten needle electrodes. Background Technology

[0002] Tungsten needle electrodes are made of materials with high melting points, corrosion resistance, high density, and good thermal and electrical conductivity. They are widely used in welding. Based on their working principle, after a certain number of uses, a hard and highly adhesive scale will form on the surface of the tungsten needle electrode, severely affecting its normal use. To ensure welding quality, the scale on the tungsten needle electrode needs to be cleaned promptly and thoroughly. When welding at heights, if the tungsten needle electrode needs cleaning, a nearby grinding wheel is usually used to grind it to avoid disrupting the work schedule. However, due to the height of the work area and sometimes the confined space, and the large size and inconvenience of moving or carrying the grinding wheel, its use is extremely inconvenient. Later, angle grinders were also used for grinding and cleaning. Although angle grinders are small and portable, when cleaning, the operator needs to hold the angle grinder in one hand and the tungsten needle electrode in the other. The interaction force increases sharply when the tungsten needle electrode comes into contact with the grinding wheel on the angle grinder, making it difficult for the operator to maintain a stable grip on the tungsten needle electrode. This not only affects the grinding quality, but also makes it inconvenient to adjust the grinding position of the tungsten needle electrode during the grinding process, resulting in a slow grinding speed and affecting the construction progress of the day to some extent. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a tungsten needle electrode-assisted grinding device that is simple in structure, compact, has good stability during operation, and helps to improve grinding efficiency and ensure grinding quality.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a tungsten needle electrode auxiliary grinding device, which can be detachably assembled on an angle grinder, including a connecting assembly part for assembly with the angle grinder, a grinding support rod fixedly connected to the connecting assembly part, a grinding adjustment frame movably mounted on the upper end of the grinding support rod, and an electrode grinding sleeve for mounting the tungsten needle electrode rotatably mounted on the grinding adjustment frame.

[0005] As a preferred technical solution, the grinding adjustment frame includes a grinding adjustment sleeve sleeved around the outer periphery of the grinding support rod, and a grinding adjustment bolt threaded through the grinding adjustment sleeve, with the inner end of the grinding adjustment bolt abutting against the surface of the grinding support rod.

[0006] As a preferred technical solution, a grinding adjustment nut is fixed on the outside of the grinding adjustment sleeve, and the grinding adjustment bolt passes through the grinding adjustment nut and the grinding adjustment sleeve in sequence.

[0007] As a preferred technical solution, an assembly bearing is fixed on the grinding adjustment sleeve, and an adjustment shaft is rotatably engaged with the assembly bearing. The outer end of the adjustment shaft is connected to the electrode grinding sleeve.

[0008] As a preferred technical solution, the connecting assembly part is configured as a metal disc, and a connecting assembly hole is provided through the metal disc.

[0009] As an improvement to the above technical solution, the grinding support rod includes a first rod and a second rod arranged in parallel, with a transition rod connecting the first rod and the second rod.

[0010] Due to the adoption of the above technical solution, the tungsten needle electrode auxiliary grinding device can be detachably assembled onto an angle grinder. It includes a connecting assembly for assembly with the angle grinder, a grinding support rod fixedly connected to the connecting assembly, a grinding adjustment frame movably mounted on the upper end of the grinding support rod, and an electrode grinding sleeve for mounting the tungsten needle electrode rotatably mounted on the grinding adjustment frame. This invention has the following advantages: a nut is fixed to the surface of the angle grinder. The entire device is installed onto the angle grinder using the connecting assembly, bolts, and nut. Under the action of the grinding support rod, the electrode grinding sleeve is supported on the side of the grinding wheel on the angle grinder.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0018] like Figures 1 to 4 As shown, the tungsten needle electrode auxiliary polishing device is used to polish the tungsten needle electrode 5 to clean the dirt formed on its surface. It can be detachably assembled onto the angle grinder 1 and essentially forms an external auxiliary tool for the angle grinder 1.

[0019] This embodiment includes a connecting assembly part for assembling with the angle grinder 1. A grinding support rod 2 is fixedly connected to the connecting assembly part, and the grinding support rod 2 is detachably assembled with the angle grinder 1 through the connecting assembly part. Specifically, the connecting assembly part is a metal disc 3 with a connecting assembly hole 4 penetrating through it. A nut that mates with the metal disc 3 is fixed to the surface of the angle grinder 1 by welding or other means. In use, the metal disc 3 is pressed onto the nut with bolts to assemble the grinding support rod 2 with the angle grinder 1. After use, the entire device is disassembled to separate it from the angle grinder 1, ensuring the normal operation of the angle grinder 1.

[0020] The grinding support rod 2 includes a first rod body 21 and a second rod body 22 arranged in parallel. A transition rod body 23 connects the first rod body 21 and the second rod body 22. Taking the direction of the attached figure as an example, the first rod body 21 is located above the second rod body 22. The second rod body 22 is used to connect to the angle grinder 1 through the metal disc 3. The transition rod body 23 realizes the spatial position transition between the first rod body 21 and the second rod body 22, so as to adjust the position of the grinding end according to the contour of the angle grinder 1, so that it can be adapted to the grinding wheel on the angle grinder 1.

[0021] The upper end of the grinding support rod 2 is movably fitted with a grinding adjustment frame, on which an electrode grinding sleeve 6 for mounting the tungsten needle electrode 5 is rotatably mounted. The grinding adjustment frame is assembled with the first rod body 21. The grinding adjustment frame can adjust the height of the electrode grinding sleeve 6 to meet the fitting requirements between it and the grinding wheel.

[0022] Specifically, the grinding adjustment frame includes a grinding adjustment sleeve 7 sleeved around the outer periphery of the grinding support rod 2, and a grinding adjustment bolt 8 threaded through the grinding adjustment sleeve 7. The inner end of the grinding adjustment bolt 8 abuts against the surface of the grinding support rod 2. The grinding adjustment sleeve 7 can drive the electrode grinding sleeve 6 to move along the grinding support rod 2 for position adjustment. After the adjustment is appropriate, the grinding adjustment sleeve 7 can be fixed on the grinding support rod 2 by the grinding adjustment bolt 8.

[0023] In this embodiment, a grinding adjusting nut is fixed to the outside of the grinding adjusting sleeve 7, and the grinding adjusting bolt 8 is sequentially disposed through the grinding adjusting nut and the grinding adjusting sleeve 7. The grinding adjusting nut can indirectly increase the contact between the grinding adjusting sleeve 7 and the grinding adjusting bolt 8, thereby improving the locking and fixing effect of the grinding adjusting bolt 8.

[0024] A mounting bearing 9 is fixed to the grinding adjustment sleeve 7, and an adjustment shaft 10 is rotatably engaged with the mounting bearing 9. The outer end of the adjustment shaft 10 is connected to the electrode grinding sleeve 6. Under the rotation of the electrode grinding sleeve 6, the grinding end of the tungsten needle electrode 5 can move up and down, allowing it to contact the grinding wheel under the operator's control for grinding. During grinding, the operator can adjust the grinding position of the tungsten needle electrode 5 by rotating the other end. The electrode grinding sleeve 6 provides support and maintains the grinding position of the tungsten needle electrode 5, resulting in better grinding effect, easier adjustment, and safer operation.
