[0018] (III) Beneficial effects Compared with the prior art, the present invention provides a precise automatic welding device for a quartz boat, which has the following beneficial effects: 1. In this precise automatic welding device for a quartz boat, by setting a flange dial indicator and a groove bar dial indicator on the outer side of the chuck and the bracket, during the steps of installing and fixing the flange and determining the welding points of the groove bars, the perpendicularity and parallelism of the flange and the groove bars are measured, avoiding the deviation during the welding of the quartz boat and the influence of the table flatness on the welding; moreover, the groove bar dial indicator can move in both the large horizontal and vertical directions and the small direction along the circumference of the universal ball structure, enabling it to adapt to the shapes and groove bar positions of most quartz boats on the market. Compared with the prior art, there is no need to build the platform again after fixing each groove bar during welding. Instead, by operating the second handwheel and the third handwheel, the position of the groove bar dial indicator can be directly changed to measure the groove bar; and the connection between the dial indicator bracket and the substrate or the support shaft is realized through a rubber support ring. The inside of this rubber support ring is a hollow structure and is made of rubber material. When the plane where the dial indicator is located is affected by the vibration caused by the movement of internal components of the device, the rubber material can effectively absorb and disperse the vibration energy, and at the same time, it can undergo elastic deformation, thereby slowing down the transmission of vibration to the dial indicator bracket and the dial indicator. The design of the hollow rubber layer further enhances its shock absorption effect. Since the middle of the rubber is hollow, when subjected to vibration, the hollow part can serve as a buffer area, absorb more vibration energy, and reduce the transmission efficiency of vibration. In actual use, this greatly reduces the influence of external vibration on the dial indicator and makes the measurement result more accurate.

[0019] 2. In this precise automatic welding device for a quartz boat, by fixedly connecting the lower surface of the movable chuck with the movable ball screw, the linear movement of the movable chuck on the upper surface of the base frame is realized by rotating the fourth handwheel, enabling the length added by this device to be flexibly adjusted and capable of adapting to the lengths of most quartz boats on the market; rotating shafts are provided at the centers of both the fixed chuck and the movable chuck. These rotating shafts are connected to the key shafts through chains and gears, and couplings are installed at the connection points of the key shafts on both sides. Therefore, the rotating shafts on both sides rotate synchronously. Then, through the transmission of bevel gears and spur gears, the rotating shafts are connected to the first handwheel, realizing the process of converting rotational motion into linear motion and then back into rotational motion. The user only needs to rotate the first handwheel externally to achieve the synchronous rotation of both chucks along the rotating shafts. Compared with the existing quartz boat welding technology that requires an experienced welder to hold the quartz boat, the operation difficulty is greatly simplified, and the device compatibility is improved.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 - 5, A precise automatic welding device for a quartz boat, including a base frame 1, a fixed chuck 11 and a moving chuck 12. In this embodiment, both the fixed chuck 11 and the moving chuck 12 (hereinafter collectively referred to as chucks) are circular, and the base frame 1 is T-shaped, including a long axis and a short axis. The fixed chuck 11 and the moving chuck 12 are coaxially installed on both sides of the long axis respectively, and substrates 3 are arranged on the outer sides; the substrates 3 are parallel to the horizontal plane, and a flange dial indicator 31 is arranged on the upper surface; a bracket 4 is installed on the short axis. On the outer surface of the side of the bracket 4 close to the base frame 1, a connecting plate 42 is connected through a vertical ball screw 41. The vertical ball screw 41 is fixedly connected to the connecting plate 42 through a nut group. A horizontal ball screw 43 is arranged on the outer side surface of the connecting plate 42, and an installation plate 44 is connected through the horizontal ball screw 43. The horizontal ball screw 43 is fixedly connected to the installation plate 44 through a nut group. A groove rod dial indicator 45 is arranged on the outer surface of the installation plate 44; the vertical ball screw 41 is connected to a second handwheel 46, and the horizontal ball screw 43 is connected to a third handwheel 47; at the upper end of the short axis, an adjusting ball screw 7 is arranged through a fixed seat. The adjusting ball screw 7 is fixedly connected to the lower surface of the upper bracket 4 through a nut group. The adjusting ball screw 7 is connected to a fifth handwheel 71, and the fifth handwheel 71 is installed on the side surface of the base frame 1. When the fifth handwheel 71 rotates, the bracket 4 has a tendency of linear motion along the direction of the adjusting ball screw 7; during use, therefore, the user can rotate the second handwheel 46, the third handwheel 47 and the fifth handwheel 71 to convert the rotational motion into a linear motion through the ball screw, thereby changing the position of the groove rod dial indicator 45 in three-dimensional directions.

[0024] In this embodiment, the groove rod dial indicator 45 is used to measure the perpendicularity and flatness of the groove rod 22 to be welded. Therefore, the flexible movement of the groove rod dial indicator 45 makes the device applicable to most models of quartz boats on the market, and the data of the groove rod 22 can be measured in all directions.

[0025] In this embodiment, flange clamping toes 13 are arranged on the outer surfaces of the fixed chuck 11 and the moving chuck 12, which are clamped and connected to the flanges 2 on both sides of the quartz boat. If the flanges 2 on both sides of the quartz boat to be measured are special-shaped flanges, a tapered groove can be opened on the outer surface of the chuck for fixing. In actual use, the staff fixes the two flanges 2 of the quartz boat with the chuck, uses the tapered groove to fix the starting point of the special-shaped flange, and then rotates the chuck, and uses the flange dial indicator 31 to measure the perpendicularity and parallelism of the two flanges 2; a number of groove rod support grooves 21 are opened on the outer surface of the flange 2. The inner surface of the groove rod support groove 21 is arc-shaped, and the diameter is the same as that of the groove rod 22 to be welded. The groove rod support grooves 21 are evenly distributed along the outer surface of the flange 2, and the number of the groove rod support grooves 21 is the same as that of the groove rods 22. In actual operation, the staff first puts the groove rod 22 into the groove rod groove, and then uses the groove rod dial indicator 45 to measure the parallelism of the groove rod 22 to determine the welding point of the groove rod 22.

[0026] Please refer to Figures 3 - 4 , a rotating shaft 14 is connected to the center of both the fixed chuck 11 and the moving chuck 12; a housing 5 is provided behind both the fixed chuck 11 and the moving chuck 12, and the interior of the housing 5 includes a chain 51, a gear 52, and an angle encoder 10; the angle encoder 10 is installed at the rear end of the rotating shaft 14 and is connected to the rotating shaft 14, and is used to convert the rotation angle of the rotating shaft 14 into an electrical signal and transmit it to the control system, which is selected according to the specific usage situation and is not shown in the accompanying drawings of the specification; the rotating shaft 14 extends into the interior of the housing 5 and is connected to a key shaft 53 through the chain 51 and the gear 52 to convert the rotational motion into a linear motion. The key shaft 53 is arranged above the base frame 1, and one is connected to each of the two chucks on both sides, with a total number of two. The two key shafts 53 are arranged coaxially and are connected through a coupling in the middle. Therefore, the two chucks on both sides rotate synchronously. The key shaft 53 on the side close to the fixed chuck 11 is connected to the first handwheel 54 through a bevel gear and a bevel gear to convert the linear motion into a rotational motion again. The number of the first handwheels 54 is one, and it is arranged outside the base frame 1; in actual use, when the operator rotates the first handwheel 54, the coaxial rotation of the fixed chuck 11 and the moving chuck 12 can be realized.

[0027] In this embodiment, a protective shell 55 is provided on the upper surface of the base frame 1, and a bracket cover 56 is provided on the outer surface of the bracket 4 to protect the internal transmission structure. A notch 561 for the horizontal movement of the mounting plate 44 is provided on the outer surface of the bracket cover 56 to avoid affecting the movement of the mounting plate 44 driven by the horizontal ball screw 43; the key shaft 53, the bevel gear, and the bevel gear are all installed inside the protective shell 55; the mounting plate 44, the connecting plate 42, and the horizontal ball screw 43 are all installed inside the bracket cover 56.

[0028] Please refer to Figures 7 - 8, there are two groove rod dial indicators 45, which are connected to the mounting plate 44 through the support shaft 441; both the bottom of the groove rod dial indicator 45 and the flange dial indicator 31 are provided with dial indicator brackets 6, and are respectively fixedly connected to the support shaft 441 and the substrate 3 through the dial indicator brackets 6; a rubber support ring 62 is provided at the bottom of the dial indicator bracket 6, and the inside of the rubber support ring 62 is a hollow structure. The lower surface of the rubber support ring 62 is fixedly connected to the support shaft 441 or the substrate 3; the inside of the rubber support ring 62 is a hollow structure and is made of rubber material. When the plane where the dial indicator is located is affected by the vibration caused by the movement of the internal components of the equipment, the rubber material can effectively absorb and disperse the vibration energy, and at the same time can undergo elastic deformation, thereby slowing down the transmission of vibration to the dial indicator bracket 6 and the dial indicator. The design of the hollow rubber layer further enhances its shock absorption effect. Since the middle of the rubber is hollow, when subjected to vibration, the hollow part can serve as a buffer area, absorb more vibration energy, and reduce the vibration transmission efficiency. In actual use, this greatly reduces the influence of external vibration on the dial indicator and makes the measurement result more accurate.

[0029] Please refer to Figures 7 - 8 , a universal ball structure 61 is provided at the connection between the dial indicator bracket 6 and the dial indicator. The universal ball structure 61 is a prior art. The dial indicator has a rotational freedom along the universal ball structure 61 on the dial indicator bracket 6. Combining with the movability of the dial indicator in the front-back, horizontal, and vertical directions, all-round measurement within a certain range can be achieved, making the equipment applicable to most models of quartz boats on the market.

[0030] Please refer to Figures 2 - 6 , a moving ball screw 15 is provided on the upper surface of the base frame 1. The moving ball screw 15 is installed on one side close to the moving chuck 12. The length of the moving ball screw 15 is determined according to the size range of the existing quartz boat. The moving ball screw 15 is fixedly connected to the moving chuck 12 through a nut group. The moving ball screw 15 is connected to the fourth handwheel 16 through bevel gears and a rotating shaft 14. The fourth handwheel 16 is arranged on the side surface of the base frame 1. When the fourth handwheel 16 rotates, the moving chuck 12 has a linear movement trend along the direction of the moving ball screw 15. During use, the position of the moving chuck 12 can be adjusted by the specific length of the groove rod 22; both the rear sides of the moving chuck 12 and the fixed chuck 11 are fixedly connected with chuck ball screws 17. The chuck ball screws 17 are connected to the sixth handwheel 18. The sixth handwheel 18 is located above the housing 5. The staff rotates the sixth handwheel 18 to move the two chucks in the vertical direction, making the equipment applicable to most quartz boats on the market.

[0031] In this embodiment, guide rails 8 arranged in parallel with the moving ball screw 15, the vertical ball screw 41, the horizontal ball screw 43 and the adjusting ball screw 7 are provided on both sides thereof. A slider 9 adapted thereto is connected to the guide rail 8. The slider 9 is fixedly connected to the ball screw and the rear surface of the component having a movement tendency when the handwheel rotates. The slider 9 has a degree of freedom of movement along the direction of the guide rail 8. Limiting the moving key by using the guide rail 8 on both sides of the ball screw can well improve the smoothness of the movement of the moving key and the stability of the device, and also prevent the device from vibrating too much during movement and affecting the data of the dial indicator.

[0032] In actual use, the operator first measures the length of the quartz boat to be welded, adjusts the position of the moving chuck 12 by rotating the fourth handwheel 16, and fixes the two flange plates 2 of the quartz boat with the chuck. Among them: the special-shaped flange plate uses the conical groove to fix the starting point, and then rotates the chuck, and uses the flange dial indicator 31 to measure the perpendicularity and parallelism of the two flange plates 2; Subsequently, the groove bar 22 is placed in the groove bar groove, the groove bar 22 is fixed, the two side groove bar dial indicators 45 are slid, the perpendicularity between the groove bar 22 and the flange plate 2 is measured, and the position degree of the groove bar 22 and the parallelism of the groove are measured with another groove bar dial indicator 45. After meeting the requirements, welding is carried out; When preparing to weld the second groove bar 22, the chuck rotates by the required angle, and the groove bar support groove 21 is adjusted to the required position, and the measurement and welding steps of the groove bar 22 are repeated until all the groove bars 22 are welded. Then, the chuck is loosened, the quartz boat is removed, and the next process is continued.

[0033] In summary, for the precise automatic welding equipment of a quartz boat, during the steps of installing and fixing the flange 2 and determining the welding points of the groove rod 22, the perpendicularity and parallelism of the flange 2 and the groove rod 22 are measured, avoiding the deviation during quartz boat welding and the influence of the table levelness on welding; moreover, the groove rod dial indicator 45 can move in both the large horizontal and vertical directions and the small direction along the circumference of the universal ball structure 61, enabling it to adapt to the shapes of most quartz boats on the market and the positions of the groove rods 22. Compared with the prior art, there is no need to build the platform again after each welding and fixing of a groove rod 22. Instead, by operating the second handwheel 46 and the third handwheel 47, the position of the groove rod dial indicator 45 can be directly changed to measure the groove rod 22; and the dial indicator support 6 is connected to the substrate 3 or the support shaft 441 through a rubber support ring 62. The inside of the rubber support ring 62 is a hollow structure made of rubber material. When the plane where the dial indicator is located is affected by the vibration caused by the movement of internal components of the equipment, the rubber material can effectively absorb and disperse the vibration energy, and at the same time can undergo elastic deformation, thereby slowing down the transmission of vibration to the dial indicator support 6 and the dial indicator. The design of the hollow rubber layer further enhances its shock absorption effect. Since the middle of the rubber is hollow, when subjected to vibration, the hollow part can serve as a buffer area to absorb more vibration energy and reduce the vibration transmission efficiency. In actual use, this greatly reduces the influence of external vibration on the dial indicator and makes the measurement result more accurate; the operation of this equipment is simple. The user only needs to rotate the first handwheel 54 externally to achieve the synchronous rotation of the two chucks along the rotating shaft 14. Compared with the existing quartz boat welding technology that requires an experienced welder to hold the quartz boat, the operation difficulty is greatly simplified and the equipment compatibility is improved.
