Description

Technical Field

[0001] This invention relates to the field of quartz boat technology, specifically to a precision automatic welding device for quartz boats. Background Technology

[0002] The main raw material for quartz boats is high-purity quartz sand or quartz rods. High-purity quartz possesses excellent properties such as high-temperature resistance, corrosion resistance, high light transmittance, and a low coefficient of expansion, making it an ideal material for manufacturing quartz boats. Quartz boats have wide applications in laboratories and industries, such as semiconductor manufacturing, chemical analysis, and medical testing. With the continuous development of these fields, the requirements for the quality and performance of quartz boats are constantly increasing. Therefore, the background technology for quartz boat manufacturing is also constantly being updated and upgraded to meet market demands and drive industry development.

[0003] Currently, quartz boats are manufactured using simple tooling to temporarily build a fixed platform. This method leads to the following problems: 1. The welded quartz boats have large deviations; 2. They cannot be used continuously, as the second boat cannot be welded directly after the first one is completed, and the fixed platform must be rebuilt; 3. They have poor compatibility, as each type of quartz boat requires a different fixed platform; 4. Platform construction requires experienced welding workers to control the welding precision of the final product, which is prone to errors. Summary of the Invention

[0004] (I) Technical problem to be solved: In view of the shortcomings of the prior art, the present invention provides a precision automatic welding equipment for quartz boats, which has the advantages of being able to control the relative position tolerance of quartz boat parts and having a measurement structure that is less affected by external factors.

The horizontal ball screw is fixedly connected to the mounting plate. The outer surface of the mounting plate is provided with... The system includes a dial indicator for the grooved bar; the vertical ball screw is connected to the second handwheel, and the horizontal ball screw is connected to the third handwheel. During use, when the second and third handwheels rotate, the vertical and horizontal ball screws tend to move linearly along their own axes. The outer surfaces of both the fixed and movable chucks are provided with flange toes, which engage with the flanges on both sides of the quartz boat. A rotating shaft is connected to the center of both the fixed and movable chucks. The outer surface of the flange has more than two grooved bar support slots. The inner surface of each grooved bar support slot is arc-shaped, with a diameter identical to that of the grooved bar to be welded.

The rotating shaft extends into the cover and is connected to a key shaft via the chain and gears. Two key shafts are located above the base frame and are placed coaxially. The two key shafts are connected by a coupling. The key shaft closer to the fixed chuck is connected to a first handwheel via a bevel gear and a slanted bevel gear. There is one first handwheel, located on the outside of the base frame. When the first handwheel rotates, the fixed chuck and the movable chuck rotate coaxially. The angle encoder is installed at the rear end of the rotating shaft and is connected to the rotating shaft.

[0007] Preferably, the upper surface of the base frame is provided with a protective shell, and the key shaft, bevel gear and conical gear are all installed inside the protective shell.

[0008] Preferably, there are two groove bar dial indicators, which are connected to the mounting plate via a support shaft; both the groove bar dial indicator and the flange dial indicator are provided with dial indicator brackets at their bottoms, which are fixedly connected to the support shaft and the base plate respectively via the dial indicator brackets.

[0009] Preferably, the dial indicator bracket has a rubber support ring at its bottom, the rubber support ring has a hollow structure inside, and the lower surface of the rubber support ring is fixedly connected to the support shaft and the base plate.

[0010] Preferably, a universal ball structure is provided at the connection between the dial indicator bracket and the dial indicator, and the dial indicator has a rotational degree of freedom along the universal ball structure on the dial indicator bracket.

[0011] Preferably, the outer surface of the bracket is provided with a bracket cover, and the outer surface of the bracket cover is provided with a slot for the mounting plate to move horizontally. The mounting plate, the connecting plate and the horizontal ball screw are all installed inside the bracket cover.

[0012] Preferably, a movable ball screw is provided on the upper surface of the base frame. The movable ball screw is installed on the side near the movable chuck and is fixedly connected to the movable chuck by a nut assembly. The movable ball screw is connected to a fourth handwheel through a bevel gear and a rotating shaft. The fourth handwheel is located on the side of the base frame. When the fourth handwheel is rotated, the movable chuck has a linear movement tendency along the direction of the movable ball screw.

When the No. 5 handwheel rotates, the bracket tends to move linearly along the direction of the adjusting ball screw.

[0015] Preferably, both sides of the movable ball screw, the vertical ball screw, the horizontal ball screw, and the adjusting ball screw are provided with guide rails placed parallel to them. A matching slider is connected to the guide rail. The slider is fixedly connected to the adjusting ball screw and has a degree of freedom of movement along the direction of the guide rail.

[0016] (III) Beneficial Effects: Compared with the prior art, the present invention provides a precision automatic welding device for quartz boats, which has the following beneficial effects:

[0017] 1. This precision automatic quartz boat welding equipment, by installing flange dial indicators and groove bar dial indicators on the outside of the chuck and on the support, measures the perpendicularity and parallelism of the flange and groove bar during the steps of installing and fixing the flange and determining the groove bar welding point. This avoids the influence of deviations during quartz boat welding and the levelness of the platform on the welding process. Furthermore, the groove bar dial indicator can move in both the horizontal and vertical directions and along the circumference of the universal ball structure, making it adaptable to most quartz boat shapes and groove bar positions on the market. Compared with existing technologies, it eliminates the need to rebuild the platform after each groove bar is welded and fixed; instead, the position of the groove bar dial indicator is directly changed by manipulating the second and third handwheels to measure the groove bar. The dial indicator bracket is connected to the base plate or support shaft via a rubber support ring. This rubber support ring has a hollow structure and is made of rubber. When the plane where the dial indicator is located is affected by vibrations caused by the movement of internal components of the equipment, the rubber material can effectively absorb and disperse the vibration energy. 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 hollow rubber layer design further enhances its shock absorption effect. Since the middle of the rubber is hollow, when subjected to vibration, the hollow part can act as a buffer area, absorbing more vibration energy and reducing the transmission efficiency of vibration. In actual use, this greatly reduces the influence of external vibrations on the dial indicator, making the measurement results more accurate.

[0018] 2. This precision automatic quartz boat welding equipment uses a fixed connection between the lower surface of the movable chuck and the movable ball screw. The linear movement of the movable chuck along the upper surface of the base frame is achieved by rotating the No. 4 handwheel, allowing for flexible length adjustment to accommodate most quartz boat lengths on the market. Both the fixed and movable chucks have a central rotating shaft, connected to a key shaft via a chain and gears. Couplings are installed at the key shaft connections on both sides, ensuring synchronous rotation of the two shafts. Through the transmission of helical bevel gears and conical gears, the shafts connect to the No. 1 handwheel, converting rotational motion into linear motion and then back into rotational motion. Users only need to externally rotate the No. 1 handwheel to achieve synchronous rotation of both chucks along the shafts. Compared to existing quartz boat welding technologies that require experienced welders to manually operate the quartz boat, this significantly simplifies operation and improves equipment compatibility.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1-5A precision automatic welding device for quartz boats includes a base frame 1, a fixed chuck 11, and a movable chuck 12. In this embodiment, both the fixed chuck 11 and the movable chuck 12 (hereinafter collectively referred to as chucks) are circular. The base frame 1 is T-shaped, including a long axis and a short axis. The fixed chuck 11 and the movable chuck 12 are coaxially mounted on both sides of the long axis, and a base plate 3 is provided on the outer side of each. The base plate 3 is parallel to the horizontal plane, and a flange dial indicator 31 is provided on its upper surface. A bracket 4 is mounted on the short axis. The outer surface of the bracket 4 near the base frame 1 is connected to a connecting plate 42 via a vertical ball screw 41. The vertical ball screw 41 is fixedly connected to the connecting plate 42 via a nut assembly. A horizontal ball screw 43 is provided on the outer surface of the connecting plate 42, and a mounting plate 44 is connected to the horizontal ball screw 43. The mounting plate 44 is fixedly connected to the nut assembly, and the outer surface of the mounting plate 44 is provided with a grooved dial indicator 45. The vertical ball screw 41 is connected to the second handwheel 46, and the horizontal ball screw 43 is connected to the third handwheel 47. The upper end of the short shaft is provided with an adjusting ball screw 7 through a fixed seat. The adjusting ball screw 7 is fixedly connected to the lower surface of the upper bracket 4 through the nut assembly. The adjusting ball screw 7 is connected to the fifth handwheel 71, which is installed on the side surface of the base frame 1. When the fifth handwheel 71 is rotated, the bracket 4 has a linear motion tendency along the direction of the adjusting ball screw 7. Therefore, in use, the user can convert the rotational motion into linear motion through the ball screw by rotating the second handwheel 46, the third handwheel 47, and the fifth handwheel 71, thereby changing the position of the grooved dial indicator 45 in the three-dimensional direction.

[0030] In this embodiment, the dial indicator 45 is used to measure the verticality and horizontality of the groove bar 22 to be welded. Therefore, the flexible movement of the dial indicator 45 makes the device suitable for most models of quartz boats on the market, and the data of the groove bar 22 can be measured in all directions.

[0031] In this embodiment, both the fixed chuck 11 and the movable chuck 12 are provided with flange toes 13 on their outer surfaces, which are snapped together with the flanges 2 on both sides of the quartz boat. If the flanges 2 on both sides of the quartz boat to be tested are irregular flanges, a tapered groove can be opened on the outer surface of the chuck for fixing. In actual use, the operator uses the chuck to fix the flanges 2 on both sides of the quartz boat, and the tapered groove is used to fix the starting point of the irregular flanges. Then the chuck is rotated, and the perpendicularity and parallelism of the two flanges 2 are measured with a flange dial indicator 31. The outer surface of the flange 2 is provided with more than two groove bar support slots 21. The inner surface of the groove bar support slot 21 is arc-shaped, and the diameter is the same as that of the groove bar 22 to be welded. The groove bar support slots 21 are evenly distributed along the outer surface of the flange 2. The number of groove bar support slots 21 is the same as that of the groove bar 22. In actual operation, the operator first puts the groove bar 22 into the groove bar slot, and then uses a groove bar dial indicator 45 to measure the parallelism of the groove bar 22 to determine the welding point of the groove bar 22.

[0032] Please see Figures 3-4 Both the fixed chuck 11 and the movable chuck 12 have a rotating shaft 14 connected to their centers. A cover 5 is located behind both the fixed chuck 11 and the movable chuck 12. Inside the cover 5 are a chain 51, a gear 52, and an angle encoder 10. The angle encoder 10 is mounted at the rear end of the rotating shaft 14 and connected to it. It converts the rotation angle of the rotating shaft 14 into an electrical signal and transmits it to the control system. The control system is selected according to the specific application and is not shown in the accompanying drawings. The rotating shaft 14 extends into the cover 5 and is connected to the key shaft 53 via the chain 51 and the gear 52, transmitting the rotational motion... The linear motion is converted into a linear motion. The key shaft 53 is set above the base frame 1, and one is connected to each of the two chucks on both sides, for a total of two. The two key shafts 53 are placed coaxially and connected in the middle by a coupling, so the two chucks on both sides rotate synchronously. The key shaft 53 on the side closer to the fixed chuck 11 is connected to the first handwheel 54 through a bevel gear and a helical bevel gear, which converts the linear motion back into rotational motion. There is one first handwheel 54, which is set on the outside of the base frame 1. In actual use, the operator can rotate the first handwheel 54 to achieve the coaxial rotation of the fixed chuck 11 and the movable chuck 12.

[0033] 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. The outer surface of the bracket cover 56 is provided with a slot 561 for the horizontal movement of the mounting plate 44 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 slanted 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.

[0034] Please see Figures 7-8Two dial indicators 45 are provided, connected to the mounting plate 44 via a support shaft 441. Both the dial indicator 45 and the flange dial indicator 31 have dial indicator brackets 6 at their bottoms, which are fixedly connected to the support shaft 441 and the base plate 3, respectively. A rubber support ring 62 is provided at the bottom of the dial indicator bracket 6. The rubber support ring 62 has a hollow internal structure, and its lower surface is fixedly connected to the support shaft 441 or the base plate 3. This rubber support ring 62 has a hollow internal structure and is made of rubber. It is located on the plane of the dial indicator. When affected by vibrations caused by the movement of internal components of the equipment, the rubber material can effectively absorb and disperse vibration energy, and at the same time, it can undergo elastic deformation, thereby slowing down the transmission of vibration to the dial indicator support 6 and the dial indicator. The hollow rubber layer design further enhances its shock absorption effect. Since the middle of the rubber is hollow, when it is subjected to vibration, the hollow part can act as a buffer area, absorbing more vibration energy and reducing the transmission efficiency of vibration. In actual use, this greatly reduces the influence of external vibrations on the dial indicator, making the measurement results more accurate.

[0035] Please see 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 existing technology. The dial indicator has a rotational degree of freedom along the universal ball structure 61 on the dial indicator bracket 6. Combined with the dial indicator's mobility in the front-back, horizontal, and vertical directions, it can achieve all-round measurement within a certain range, making the device suitable for most models of quartz boats on the market.

[0036] Please see Figures 2-6 A movable ball screw 15 is provided on the upper surface of the base frame 1. The movable ball screw 15 is installed on the side near the movable chuck 12. The length of the movable ball screw 15 is determined according to the size range of existing quartz boats. The movable ball screw 15 is fixedly connected to the movable chuck 12 through a nut assembly. The movable ball screw 15 is connected to the fourth handwheel 16 through a bevel gear and a rotating shaft 14. The fourth handwheel 16 is located on the side of the base frame 1. When the fourth handwheel 16 rotates, the movable chuck 12 tends to move linearly along the direction of the movable ball screw 15. In use, the position of the movable chuck 12 can be adjusted by the specific length of the groove bar 22. The rear sides of the movable chuck 12 and the fixed chuck 11 are both fixedly connected to chuck ball screws 17. The chuck ball screws 17 are connected to the sixth handwheel 18. The sixth handwheel 18 is located above the cover 5. The operator can move the chucks on both sides in the vertical direction by rotating the sixth handwheel 18, making the device suitable for most quartz boats on the market.

[0037] In this embodiment, guide rails 8 are provided on both sides of the movable ball screw 15, the vertical ball screw 41, the horizontal ball screw 43, and the adjusting ball screw 7, and are placed parallel to them. A matching slider 9 is connected to the guide rail 8. The slider 9 is fixedly connected to the adjusting ball screw 7 and has a degree of freedom of movement along the guide rail 8. Using guide rails 8 on both sides of the ball screw to limit the movement of the movable key can greatly increase the smoothness of the movement of the movable key and the stability of the equipment, and also prevent excessive vibration of the equipment during movement from affecting the dial indicator data.

[0038] 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 No. 4 handwheel 16, and fixes the two flanges 2 on both sides of the quartz boat with the chuck. Among them, the starting point of the irregular flange is fixed with a tapered groove. Then, the chuck is rotated, and the perpendicularity and parallelism of the two flanges 2 are measured with the flange dial indicator 31. Then, the groove bar 22 is placed into the groove bar groove, the groove bar 22 is fixed, and the groove bar dial indicators 45 on both sides are slid to measure the perpendicularity of the groove bar 22 and the flange 2. The position of the groove bar 22 and the parallelism of the groove are measured with another groove bar dial indicator 45. After the requirements are met, welding is carried out. When preparing to weld the second groove bar 22, the chuck is rotated to the required angle, 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 groove bars 22 are welded. The chuck is then released, the quartz boat is removed, and the next process is continued.

[0039] In summary, this precision automatic welding equipment for quartz boats measures the perpendicularity and parallelism of the flange 2 and the groove bar 22 during the steps of installing and fixing the flange 2 and determining the welding point of the groove bar 22. This avoids the influence of deviations during quartz boat welding and the levelness of the platform on the welding process. Furthermore, the groove bar dial indicator 45 can move in both the horizontal and vertical directions and along the circumference of the universal ball structure 61, allowing it to adapt to the shapes of most quartz boats and the positions of the groove bars 22 on the market. Compared with existing technologies, it eliminates the need to rebuild the platform after each groove bar 22 is welded and fixed. Instead, the position of the groove bar dial indicator 45 can be directly changed by manipulating the second handwheel 46 and the third handwheel 47 to measure the groove bar 22. The dial indicator bracket 6 is connected to the base plate 3 or the support shaft 441 via a rubber support ring 62, which has a hollow internal structure. Made of rubber, the dial indicator effectively absorbs and disperses vibration energy when the plane of the dial indicator is affected by vibration caused by the movement of internal components. It also undergoes elastic deformation, thus mitigating the transmission of vibration to the dial indicator support 6 and the dial indicator itself. The hollow rubber layer further enhances its shock absorption effect. Because the rubber is hollow in the middle, the hollow part acts as a buffer zone when subjected to vibration, absorbing more vibration energy and reducing the transmission efficiency of vibration. In practical use, this significantly reduces the influence of external vibrations on the dial indicator, making the measurement results more accurate. The device is easy to operate; the user only needs to turn the No. 1 handwheel 54 externally to achieve synchronous rotation of the two chucks along the shaft 14. Compared with existing quartz boat welding technology, which requires experienced welders to hold the quartz boat, this greatly simplifies the operation and improves the equipment's compatibility.
