Description

Technical Field

[0001] The utility model relates to a tungsten electrode dust-proof visual grinding device, belonging to the grinding technology field, and mainly solving the problems of visual grinding and dust prevention at the tip and end of the tungsten electrode. Background Art

[0002] During tungsten inert gas welding, the tungsten electrode needs to be ground frequently. Manual grinding of the tungsten electrode cannot guarantee the grinding angle and quality, and the dust generated during the grinding process of the tungsten electrode will be harmful to the human body. Therefore, using a tungsten electrode grinding machine for tungsten electrode grinding is an effective measure to solve the above problems. However, most of the existing tungsten electrode grinding machines can only grind the tip and cannot grind the end. When grinding the tungsten electrode, the feeding speed and rotation angle cannot be effectively observed and controlled from the front, which cannot meet the use requirements and thus affect the welding quality. The tungsten electrode dust generated during grinding cannot be treated either. A small number of multi-functional tungsten electrode grinding machines are too expensive to afford. Therefore, developing a practical tungsten electrode dust-proof visual grinding device has great market prospects. Summary of the Invention

[0003] The purpose of the utility model is to solve the problems existing in the above background art, and provide a tungsten electrode dust-proof visual grinding device. When grinding the tip and end of the tungsten electrode, the upper and left transparent covers can effectively observe and control the grinding rotation angle and feeding speed. The dust removal double-sided adhesive tape has a good protective effect. Its structure is reasonable, the functions are complete, the volume is small, the noise is small, and it is convenient to use. To solve the above technical problems, the technical solution adopted by the utility model is: a tungsten electrode dust-proof visual grinding device, including a chassis, a grinding disc driving unit and an angle-adjusting gripper. The DC motor is fixed inside the base to drive the grinding disc to rotate and work. The angle-adjusting gripper is installed above the base guide rail and consists of a guide groove base, an angle-adjusting upper seat, a fine-tuning nut and a tungsten electrode clamping handle. A hexagonal lock hole and a flat head guide hole are provided above the grinding chamber, which are used for tightening the spring locking nut and grinding the end after the tip of the tungsten electrode is ground respectively. Transparent covers are installed above and on the left side of the grinding chamber to facilitate observing the grinding situation of the tungsten electrode. The inner wall of the grinding chamber is adhered with a dust removal double-sided adhesive tape to reduce the harm of dust to the staff.

[0004] As an optimal solution, the chassis is welded by steel plates and consists of two parts: a base and a grinding chamber. The DC motor is fixed inside the base to prevent vibration during operation. Capacitors, resistors, rectifier bridges, fuse sockets, switches, power sockets, etc. are also enclosed inside the base to ensure electrical safety. The angle-adjusting gripper is marked with an angle scale, enabling multi-angle adjustment. The tungsten electrode gripper includes a tungsten electrode, a spring lock nut, a tungsten electrode spring chuck, a rotating handle, and a handle extension rod. The tungsten electrode is fixed inside the tungsten electrode gripper through the spring lock nut and the tungsten electrode spring chuck. The fine-tuning nut is threadedly connected to the adjusting upper seat. The tungsten electrode gripper slides and fits inside the handle nylon guide sleeve, enabling the tungsten electrode to make a slight contact with the grinding disc for grinding. The transparent cover is installed above and on the left side of the grinding chamber for easy observation of the tungsten electrode grinding situation. A rubber gasket is added between the transparent cover and the grinding chamber, and a dust-removing double-sided adhesive tape is adhered to the inner wall of the grinding chamber to prevent dust leakage and noise generation. A flat-head guide hole for grinding the end of the tungsten electrode and a hexagonal lock hole for tightening the spring lock nut are provided in the upper left corner of the grinding chamber.

[0005] The beneficial effects of the present utility model: This tungsten electrode dust-proof and visible grinding device adjusts the required angle according to the needs of tungsten inert gas welding through the scale of the angle-adjusting gripper, moves along the guide rail, observes and adjusts the tungsten electrode grinding situation through the transparent covers above and on the left side. The dust generated during grinding is enclosed in the grinding chamber and adheres to the dust-removing double-sided adhesive tape, which can be replaced and removed after shutdown. This structure is reasonable in design, complete in function, small in size, low in noise, and convenient to use.
