Description

Technical Field

[0001] This utility model relates to the field of quartz boat processing technology, specifically to a welding device for heat processing of black quartz boats. Background Technology

[0002] Black quartz boats are products made of black quartz material and assembled with high-precision machinery. The main structure of a quartz boat typically consists of grooved bars and plate-shaped crystals. Compared to traditional quartz materials, black quartz boats break through the temperature resistance limit of 1730°C and increase the softening point to about 2000°C, maintaining stable physical and chemical properties in high-temperature environments.

[0003] According to Chinese Patent Publication No. CN221644789U, "A Welding Device for Fire Processing of Quartz Boats," the device mainly describes a system where vacuum chambers A and B are connected to a clamping mechanism via covers A and B. Suction cups are connected to vacuum chambers A and B via flexible hose A. One set of suction cups is angled upwards while the other is angled downwards, ensuring better fixation of the quartz boat's curved surface. The welding mechanism is connected to an electric telescopic rod B via a slider. The electric telescopic rod B extends and retracts within a groove, pushing the slider to move. The quartz welding torch is connected to a support via a robotic arm. The robotic arm swings up and down, enabling the welding torch to move vertically. A sliding block moves within a groove A via a spring. After the fixing mechanism secures the quartz boat, the spring is in a stretched state. The welding mechanism then begins heating and welding the quartz boat. During welding, the quartz glass softens, causing the spring to contract and pull the sliding block, moving one side of the quartz boat to the other, thus reducing the weld gap. This achieves the effect of preventing excessively large weld gaps during the welding process.

[0004] Typically, during welding, a spring is used to move one side of the quartz boat to the other to reduce gaps during welding. However, the spring pull causes uneven force on the weld, affecting its uniformity and increasing the complexity and difficulty of the operation.

[0005] Therefore, a welding device for heat treatment of black quartz boats is proposed to solve the problem that the internal structure of the quartz boat is brought closer together by spring pulling, which affects the uniformity of the weld. Utility Model Content

[0006] The technical problem to be solved by this utility model is that the internal structure of the quartz boat is brought closer together by the spring, which affects the uniformity of the weld. Therefore, a welding device for heat processing of black quartz boats is proposed.

[0007] The technical solution adopted by this utility model to solve the technical problem is: a welding device for black quartz boat fire processing, including a fixed plate, a first groove is formed on the fixed plate, and connecting holes are uniformly formed on one side of the fixed plate located in the first groove. A positioning rod is inserted into the connecting hole, and a first slider is sleeved on the positioning rod. A support column is fixedly connected to the upper end of the first slider, and a slot is fixedly connected to the upper end of the support column. A connecting rod is fixedly connected to one side of the first slider, and a second slider is sleeved on the connecting rod. An electric push rod is fixedly connected to the upper end of the second slider, and a stop block is fixedly connected to the upper end of the electric push rod. A stop hole is formed on the side of the stop block near the first slider. A mechanical arm is provided on one side of the fixed plate, and a welding gun is fixedly connected to the end of the mechanical arm. A support plate is fixedly connected to the upper side of the fixed plate, and an adjusting rod is fixedly connected to the support plate. A pressure plate is threadedly connected to the adjusting rod.

[0008] As a preferred technical solution of this utility model, the upper end of the fixing plate is in contact with a connecting frame, and heat pipes are uniformly fixedly connected inside the connecting frame. A first motor is fixedly connected to one side of the connecting frame, and a guide fan is fixedly connected to the output end of the first motor. By setting up heat pipes and a guide fan, the components inside the quartz boat can be preheated by allowing heat flow to diffuse.

[0009] As a preferred technical solution of this utility model, a sliding rod is inserted into the bottom side of the connecting frame. The sliding rod is located in the limiting groove, and the limiting groove is located on the fixed plate. By setting the sliding rod, the movement of the connecting frame can be facilitated.

[0010] As a preferred technical solution of this utility model, a connecting strip is in contact with one side of the fixing plate, and an insertion hole is provided on the connecting strip. The insertion hole corresponds to the connecting rod. By setting the connecting strip and the insertion hole, the connecting roller and the positioning rod can be matched to provide a limit for the connecting rod.

[0011] As a preferred technical solution of this utility model, a limiting rod is inserted into one side of the connecting strip, and the limiting rod is threadedly connected to the fixing plate. By setting the limiting rod, the connecting rod can be adjusted and increased, thereby correspondingly placing multiple slotted bars.

[0012] This utility model has the following advantages: the groove bar can be limited by the stop hole on the stop block and the slot. The second slider contacts the bottom side of the first groove and the plate-shaped crystal surface is limited by the pressure plate on the support plate. Then, one side of the groove bar contacts the plate-shaped crystal surface. The internal parts of the quartz boat are preheated by the heat pipe. At this time, the robotic arm drives the welding gun to move to realize the welding gun movement welding, which improves the welding uniformity and reduces the operation difficulty.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Please refer to the following: Figure 1-3 The welding device for black quartz boat heat treatment shown includes a fixed plate 1 with a first groove 2. Connecting holes 3 are evenly distributed on one side of the first groove 2. Multiple first sliders 5 can be placed by using the connecting holes 3 in conjunction with first sliders 5 and positioning rods 4, allowing slots 7 to correspond to multiple slotted rods to be placed. Positioning rods 4 are inserted into the connecting holes 3, and first sliders 5 are sleeved on the positioning rods 4. A support column 6 is fixedly connected to the upper end of the first slider 5, and slots 7 are fixedly connected to the upper end of the support column 6. A connecting rod 8 is fixedly connected to one side of the first slider 5, and a second slider 9 is sleeved on the connecting rod 8. The second slider 9 contacts the first groove 2. The position is fixed by friction. At this time, the grooved rod and the plate-shaped crystal surface are in contact. The upper end of the second slider 9 is fixedly connected to an electric push rod 10. The electric push rod 10 drives the stop block 11 to move up and down, which can adjust the position of the stop block 11. The upper end of the electric push rod 10 is fixedly connected to the stop block 11. The stop block 11 has a stop hole on the side near the first slider 5. A mechanical arm 12 is set on one side of the fixed plate 1. A welding gun 13 is fixedly connected to the end of the mechanical arm 12. A support plate 14 is fixedly connected to the upper side of the fixed plate 1. An adjusting rod 15 is fixedly connected to the support plate 14. A pressure plate 16 is threaded on the adjusting rod 15. Rotating the pressure plate 16 can cause the pressure plate 16 to squeeze and limit the plate-shaped crystal surface.

[0019] The upper end of the fixed plate 1 is in contact with the connecting frame 17. Heat pipes 18 are uniformly fixedly connected inside the connecting frame 17. The heat pipes 18 are connected to an external power supply through wires. A first motor is fixedly connected to one side of the connecting frame 17. A guide fan 19 is fixedly connected to the output end of the first motor. The heat generated by the heat pipes 18 causes the temperature inside the connecting frame 17 to rise and comes into contact with the quartz boat to generate preheating.

[0020] The connecting frame 17 has a sliding rod 20 inserted into its bottom side. The sliding rod 20 is located in the limiting groove 21, which is located on the fixing plate 1. By setting the sliding rod 20, the connecting frame 17 can be moved.

[0021] One side of the fixing plate 1 is in contact with a connecting strip 22, and the connecting strip 22 has a socket 23, which corresponds to the connecting rod 8. By setting the connecting strip 22 and the socket 23, a limit can be provided at one end of the connecting rod 8, thereby improving stability.

[0022] Among them, a limiting rod 24 is inserted into one side of the connecting strip 22, and the limiting rod 24 is threadedly connected to the fixing plate 1. By setting the limiting rod 24, the connecting strip 22 can be disassembled, and the connecting rod 8 can be added or removed.

[0023] Working principle: Add connecting rod 8, first slider 5 and second slider 9 according to the required number of grooved bars. Then use connecting strip 22 and limiting rod 24 to provide limiting in conjunction with connecting hole 3 and positioning rod 4. At this time, place the grooved bar in the slot 7 and connect it with the stop hole. Then place the plate-shaped crystal surface on the adjusting rod 15 on one side of the support plate 14. Then rotate the pressure plate 16 to limit the plate-shaped crystal surface. The second slider 9 contacts the first groove 2. The friction generated makes the second slider 9 keep stable. At this time, one end of the grooved bar contacts the plate-shaped crystal surface. Move the connecting frame 17 so that one side of the connecting frame 17 covers the robotic arm 12 and welding gun 13. Start the external equipment and make the heat pipe 18 heat the components in the quartz boat to form preheating. Start the welding gun 13 and heat the contact surface between the plate-shaped crystal surface and the grooved bar, thereby facilitating the connection between the plate-shaped crystal surface and the grooved bar, which can improve the welding effect and reduce the difficulty of operation.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0025] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.
