Description

Technical Field

[0001] The utility model relates to a correction device, in particular to an auxiliary correction device for light rod welding. Background Art

[0002] Optical rods are high-purity, rod-shaped raw materials used in optical fiber production. To ensure continuous production, optical rods of limited length must be welded. During optical rod welding, the ends of the rods are heated using a flame, arc, or laser, melting the ends. The weld is then completed by fusing the molten ends together. During optical rod welding, the ends of the two rods must be aligned to prevent misalignment during welding and ensure uniform fiber drawing at the welded joint. Due to the high temperatures required to melt optical rods, typically exceeding 2000°C, it is difficult to manipulate and align the rods at the molten end. The current method involves manipulating the rods at the other end, away from the high temperature. This movement and angle adjustment of the other end of the rod drive the movement of the molten end, ensuring alignment. However, due to the length of individual optical rods, even slight errors in the molten end of the rod can be amplified by the movement of the molten end, making alignment difficult and challenging. Therefore, it is necessary to design a light rod welding auxiliary correction device to solve the above problems. Summary of the Invention

[0003] The utility model aims to provide a light rod welding auxiliary correction device which can move the molten end of the light rod and conveniently and accurately butt the molten end of the light rod.

[0004] The technical solution of the utility model is:

[0005] The invention discloses an auxiliary correction device for light rod welding, which consists of a handle and a refractory rod. The device is characterized in that the refractory rod is arranged on the handle, one end of the refractory rod is fixedly connected to the handle, and the other end of the refractory rod is symmetrically provided with a guide surface.

[0006] A clip is symmetrically arranged on the end surface of the handle on one side of the refractory rod. The clip is in an arc shape and is sleeve-connected to the refractory rod.

[0007] The clamping piece is provided with a fixing bolt, and the clamping piece is fixedly connected to the refractory rod through the fixing bolt.

[0008] The guide surface is in a slope shape, and the inclination angle of the guide surface is 15-60 degrees.

[0009] The thickness of the end surface of the refractory rod between the guide surfaces is 10-15 mm.

[0010] The beneficial effects of the present invention are:

[0011] This light rod welding auxiliary correction device allows the refractory rod's guide surface to directly contact the molten tip of the light rod, adjusting the position of the molten tip. This direct adjustment allows for easy, convenient, and accurate adjustment of the molten tip. Because the guide surface is an inclined plane, the light rod is less likely to slip out of the guide's range when it is pushed to adjust its position. This solves the difficulty of existing adjustment methods. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] This light rod welding auxiliary correction device consists of a handle 1 and a refractory rod 2, with the refractory rod 2 being mounted on the handle 1. Preferably, the refractory rod 2 is made of graphite, which is resistant to high temperatures and can directly contact the molten end of the light rod to guide it. Graphite can also burn at high temperatures to generate carbon dioxide, which evaporates and is unlikely to remain on the surface of the light rod. Therefore, when the graphite refractory rod is used to guide the light rod, impurities are not introduced onto the surface of the light rod. The handle 1 is made of insulating plastic, rubber, or wood to isolate the high temperature conducted by the graphite and prevent hand burns.

[0015] One end of the refractory rod 2 is fixedly connected to the handle 1, and the other end of the refractory rod 2 is symmetrically provided with a guide surface 3. The guide surface 3 is in the shape of a slope, and the inclination angle of the guide surface 3 is 15-60 degrees. When the refractory rod 2 moves the end of the light rod through the guide surface, the cylindrical light rod contacts the guide surface 3. Since the guide surface 3 is an inclined plane, even if the light rod slides, there is a large sliding range. Within the range of the guide surface 3, the light rod is not easy to slip off the refractory rod 2. Because the guide surface 3 is set in an inclined shape, when the light rod is moved through the guide surface 3, the refractory rod 2 and the light rod are in an inclined contact, so that the hand can stay away from the light rod, avoiding the heat conducted from the light rod from burning the hand skin. The smaller the inclination angle of the guide surface 3, the closer the hand is to the light rod, but the smaller the inclination angle of the guide surface 3, the larger the contact area between the guide surface 3 and the light rod, and the less likely the light rod is to deform. The larger the inclination angle of the guide surface 3, the farther the hand is from the light rod, and the less likely the hand will be burned. However, the larger the inclination angle of the guide surface 3, the smaller the contact area between the guide surface 3 and the light rod, and the easier it is for the molten light rod end to deform.

[0016] A clip 4 is symmetrically arranged on the end surface of the handle 1 on one side of the refractory rod 2. The clip 4 is in the shape of an arc and is connected to the refractory rod 2 in a sleeve manner. A fixing bolt 5 is provided on the clip 4, and the clip 4 is fixedly connected to the refractory rod 2 via the fixing bolt 5. The function of the clip is to limit the deviation of the refractory rod 2 and provide a radial support force for the refractory rod 2, so that the handle 1 can push the refractory rod 2 to move radially through the clip 4, and then the refractory rod 2 can push the polishing rod to move through the radial movement of the refractory rod 2, so that the polishing rod end is aligned.

[0017] The end face thickness of the refractory rod 2 between the guide surfaces 3 is 10-15mm. The end face thickness of the refractory rod 2 between the guide surfaces 3 should not be too small. If the end face thickness of the refractory rod 2 between the guide surfaces 3 is too small, the graphite refractory rod will easily break when subjected to stress and high temperature.

[0018] To use this polished rod welding auxiliary correction device, after the polished rod end has melted, tilt the refractory rod 2 toward the polished rod, so that the guide surface 3 of the refractory rod 2's end lies flush against the molten end of the polished rod. Pushing the handle 1 sequentially applies a lateral (i.e., radial) thrust to the polished rod, which in turn is driven by the handle 1, the clip 4, the refractory rod 2, and the guide surface 3, pushing the polished rod end to move and thereby align the polished rod ends. Compared to correcting the position of the molten end by moving the other end of the polished rod, directly pushing the molten end of the polished rod allows for convenient, easy, and accurate correction.

[0019] This light rod welding auxiliary correction device allows the guide surface 3 of the refractory rod 2 to directly contact the molten end of the light rod, adjusting the position of the molten end. Since the position of the molten end of the light rod is directly adjusted, the position of the molten end of the light rod can be easily, conveniently, and accurately adjusted. Because the guide surface 3 is an inclined plane, the light rod is unlikely to slip out of the range of the guide surface when it is pushed to adjust its position. This solves the difficulty of existing adjustment methods.
