Description

Technical Field

[0001] This invention belongs to the field of tooling and fixture technology, and particularly relates to a quartz carrier welding fixture and its welding process. Background Technology

[0002] Quartz carriers generally refer to tools or devices made of quartz material used to carry, support, or fix other objects. Quartz, as a material with high hardness, high melting point, good chemical stability and thermal stability, is widely used in the manufacture of carriers in various high temperature, high pressure or corrosive environments.

[0003] Quartz carriers come in a variety of forms and have a wide range of uses, including quartz crucibles, quartz tubes, and quartz boats. Some tools, such as quartz tubes and quartz boats, usually require welding. Specifically, quartz tubes usually require quartz flanges to be welded to their end faces.

[0004] For example, Chinese patent application number (2019110487187) discloses a vertical welding device and method for quartz tubes. This application achieves butt welding of equal-diameter end caps and quartz tubes through vertical welding. After use, both the end caps and quartz tubes can be recut and reused, saving costs. The welded joint is smooth, avoiding air leakage that may be caused by uneven welded joints. However, this application does not test the quartz tube after placement. When there is a slight inclination angle between the quartz tube and the quartz flange, or when the quartz tube is placed at a slight tilt, it is easy for the quartz tube and the quartz flange to not be vertically connected after welding, affecting product quality. This can easily lead to large local tensile forces at the connection between the quartz tube and the quartz flange during subsequent use, or even cracks. Summary of the Invention

[0047] S2: Place the quartz flange in the mounting slot of the limiting plate and tighten the adjusting screw;

Then, the connection between the two is welded by the welding gun mechanism, which effectively ensures the product quality of the quartz tube and avoids excessive local tensile force due to the connection of the quartz flange during subsequent use.

[0054] 2. By setting a scale inside the limiting plate used to place the quartz flange and adjusting it with an adjusting screw, the position of the adjusting block is set based on the diameter / radius of the mounting groove and the diameter / radius of the quartz flange. This effectively ensures that the axis of the quartz flange coincides with the axis of the limiting plate, further guaranteeing the product quality after the quartz tube and the quartz flange are welded.

[0055] 3. By detecting whether there is any offset in the X and Y axes of the quartz tube, it is easy to ensure that the quartz tube is perpendicular to the quartz flange by adjusting only the X and Y axes of the quartz tube through the adjustment component.

[0056] 4. By employing two detection rods, the difference in values ​​between the two detection rods in the X-axis detection component can be used to detect whether the quartz tube has an offset on the Y-axis. Similarly, the difference in values ​​between the two detection rods in the Y-axis detection component can be used to detect whether the quartz tube has an offset on the X-axis, thereby effectively ensuring the accuracy and efficiency of the detection.

[0065] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0066] Example 1:

[0067] This embodiment provides a quartz carrier welding fixture. The quartz carrier includes a quartz tube and a quartz flange. The welding fixture includes:

[0068] Machine body 1, equipped with processing platform 2;

[0069] A rotary table 3 is mounted on a processing platform 2 and is equipped with a limiting plate 4 for mounting a quartz flange.

[0070] The tube clamping mechanism 5 is installed on the processing platform 2 and is used to cooperate with the limiting plate 4 to axially clamp the quartz tube;

[0071] The testing unit 6 is installed on the processing platform 2 and is used to detect whether the quartz tube is tilted.

[0072] The welding torch mechanism is used to weld the joint between quartz tubes and quartz flanges.

[0073] The pressing mechanism 5 is equipped with an adjustment component 50 for adjusting the quartz tube to eliminate tilting.

[0074] Meanwhile, the welding torch mechanism can be fixed on the processing platform 2 or handheld. The method of fixing it on the processing platform 2 specifically includes a welding torch, a lifting bracket for mounting the welding torch, and a linear horizontal drive unit for driving the lifting bracket and the welding torch to move horizontally (not shown in the specification, it is existing mature technology, please refer to patent 2019110487187, which will not be elaborated here).

[0075] Furthermore, the rotary table 3 is a mature existing technology, and its specific structure will not be described in detail here.

[0076] As can be seen from this embodiment, the detection mechanism 6 is set to detect whether the quartz tube is tilted after being placed and axially fixed by the tube pressing mechanism 5. When the quartz tube is tilted, it is adjusted by the adjusting component 50 to make it perpendicular to the quartz flange, thus eliminating the tilt of the quartz tube. Then, the welding gun mechanism is used to weld the connection between the two, which effectively ensures the product quality of the quartz tube and avoids the possibility of cracks due to excessive local tensile force during subsequent use of the quartz flange connection.

[0077] Example 2:

[0078] This embodiment provides a quartz carrier welding fixture, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including the limiting plate 4:

[0079] The main body 40 is detachably mounted on the rotary table 3 and has a mounting groove 41 for mounting a quartz flange.

[0080] Adjusting block 42 is slidably connected within mounting slot 41;

[0081] The adjusting screw 43 is provided through the inner wall of the mounting groove 41 and is threadedly connected to the main body 40. One end is connected to the bearing of the adjusting block 42, and the other end is provided with an adjusting handle 430.

[0082] A scale 44 is set on the bottom wall of the mounting groove 41 and is used to indicate the straight-line distance between the side of the adjusting block 42 near the axis of the mounting groove 41 and the axis of the mounting shaft.

[0083] Among them, the adjusting block 42 is arc-shaped on the side near the axis, which makes it easy to fit with the quartz flange. There are four adjusting blocks 42 and four adjusting screws 43, which are evenly spaced around the circumference. The scale 44 can be embedded, that is, the surface is flush with the bottom wall of the mounting groove 41, or it can be engraved directly on the bottom wall of the mounting groove 41.

[0084] Furthermore, in order to make it easier for the scale 44 to indicate the straight-line distance between the side of the adjusting block 42 near the axis of the mounting groove 41 and the axis of the mounting shaft, the scale 44 is specifically designed so that the size values ​​increase sequentially from the axis outwards, and the side of the adjusting block 42 away from its arc surface is used as the reading end, which makes it easier to read the size values. However, this setting requires the scale 44 to be moved as a whole away from the axis by an amount equivalent to the thickness of the adjusting block 42.

[0085] As can be seen from this embodiment, by setting a scale 44 in the limiting plate 4 used to place the quartz flange and adjusting it by adjusting the screw, the position of the adjusting block 42 is set based on the diameter / radius size of the mounting groove 41 and the diameter / radius size of the quartz flange, thereby effectively ensuring that the axis of the quartz flange coincides with the axis of the limiting plate 4, and further ensuring the product quality after the quartz tube and the quartz flange are welded.

[0086] Furthermore, it employs four adjusting blocks 42 and adjusting screws 43, meaning that when welding quartz flanges from the same batch, only two vertically related adjusting screws 43 need to be loosened to remove the welded product and place the product to be welded, eliminating the need for repeated adjustments and improving convenience.

[0087] Example 3:

[0088] This embodiment provides a quartz carrier welding fixture, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0089] The testing unit 6 includes an X-axis testing component 61Y60X and a Y-axis testing component 61Y60X;

[0090] The X-axis detection component 61Y60X and the Y-axis detection component 61Y60X are respectively installed on the two sides of the rotary table 3.

[0091] As can be seen from this embodiment, by detecting whether there is any offset in the X-axis and Y-axis of the quartz tube, it is easy to ensure that the quartz tube is perpendicular to the quartz flange by adjusting only the X-axis and Y-axis of the quartz tube through the adjustment component 50.

[0092] Example 4:

[0093] This embodiment provides a quartz carrier welding fixture, which, in addition to the technical solution of the above embodiment, also has the following technical features: both the X-axis detection component 61Y60X and the Y-axis detection component 61Y60X include:

[0094] The first drive unit 600 is installed on the processing platform 2, and the output end is provided with a first support frame 611, which is used to drive the first support frame 611 to move closer to or away from the limiting plate 4.

[0095] The detection rod 601 is slidably connected to the first support frame 611, with one end extending above the limiting plate 4 and abutting against the surface of the quartz tube, and the other end is provided with a ranging component;

[0096] Spring 602 is sleeved on the surface of detection rod 601 and is used to reset detection rod 601.

[0097] As can be seen from this embodiment, by detecting the extension and retraction of the detection rod 601 and comparing it with the extension and retraction of the detection rod 601 under normal conditions, it can be determined whether there is a tilted placement. The structure is simple and highly automated and convenient, while the spring 602 facilitates the reset of the detection rod 601.

[0098] Example 5:

[0099] This embodiment provides a quartz carrier welding fixture, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0100] The center point of the limiting disk 4 is provided with a shaft, and an axis is provided through the shaft and perpendicular to the limiting disk 4;

[0101] A first reference plane 7 is set through the axis, parallel to the X-axis, and perpendicular to the horizontal plane;

[0102] A second reference plane 8 is set through the axis, parallel to the Y-axis, and perpendicular to the horizontal plane;

[0103] There are two detection rods 601, and the two detection rods 601 in the X-direction detection assembly 61Y60X are symmetrically arranged along the first reference plane 7, and the two detection rods 601 in the Y-direction detection assembly 61Y60X are symmetrically arranged along the second reference plane 8.

[0104] As can be seen from this embodiment, by using two detection rods 601, that is, by the numerical difference between the two detection rods 601 in the X-axis detection component 61Y60X, the offset of the quartz tube on the Y-axis can be detected. Similarly, by the numerical difference between the two detection rods 601 in the Y-axis detection component 61Y60X, the offset of the quartz tube on the X-axis can be detected, thereby effectively ensuring the accuracy and efficiency of the detection.

[0105] Meanwhile, when there is only a single detection rod 601, that is, the X-axis detection component 61Y60X is used to detect whether there is a displacement in the X-axis of the quartz tube, and the Y-axis detection component 61Y60X is used to detect whether there is a displacement in the Y-axis of the quartz tube. This has a defect. Specifically, when there is a displacement in the X-axis of the quartz tube but no displacement in the Y-axis, both the X-axis detection component 61Y60X and the Y-axis detection component 61Y60X may detect the displacement. This is because the surface of the quartz tube is curved. When the quartz tube tilts upward in the X-axis, the contact point between the surface of the quartz tube and the detection rod 601 in the Y-axis detection component 61Y60X will change, that is, a displacement will occur in the Y-axis. This will increase the number of adjustments of the adjustment component 50 and affect the calibration efficiency.

[0106] Therefore, by using the two detection rods 601 as described above and comparing the numerical differences between the two detection rods 601, it is possible to determine whether there is an offset in the X-axis or Y-axis direction. This can effectively eliminate the above-mentioned defects, reduce the number of adjustments, and improve the calibration efficiency.

[0107] Example 6:

[0108] This embodiment provides a quartz carrier welding fixture, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the ranging component includes:

[0109] The support platform 603 is installed on the first support frame 611 and is located on the side of the first support frame 611 away from the limiting plate 4;

[0110] The base 604 is installed on the support platform 603, and slide rails 605 are provided on both sides, and sliders 606 are slidably connected on the slide rails 605.

[0111] The rod clamp 607 is sleeved on the surface of the detection rod 601 and is used for the connection between the detection rod 601 and the slider 606;

[0112] The ranging unit 608 is mounted on the support platform 603 and is used to detect the starting position, ending position and distance of movement of the detection rod 601, and provide feedback.

[0113] Among them, the ranging unit 608 is existing technology. Specifically, it uses a photoelectric sensor to detect the starting position and ending position of the movement of the detection rod 601, uses an encoder to detect the distance moved, and processes and provides feedback through a microprocessor. Its specific structure will not be described in detail here.

[0114] As can be seen from this embodiment, by setting up the support platform 603, the base 604 and the slide rail 605, and connecting them with the slider 606 and the rod clamp 607, the stability and smoothness of the movement of the detection rod 601 are effectively improved, ensuring the detection accuracy.

[0115] Example 7:

[0116] This embodiment provides a quartz carrier welding fixture, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0117] A U-shaped frame 609 is provided at the end of the detection rod 601 away from the ranging component, and the opening of the U-shaped frame 609 faces the side away from the ranging component, and a roller 610 is rotatably connected inside the U-shaped frame 609;

[0118] Among them, a rotating shaft is provided at the center of the roller 610, and the roller 610 and the rotating shaft are connected by a bearing.

[0119] As can be seen from this embodiment, by setting a roller 610 at the end of the detection rod 601 away from the ranging component, that is, by using the roller 610 to roll and connect the end of the detection rod 601 to the quartz tube, the detection rod 601 can move continuously when the adjusting component 50 adjusts the quartz tube, thereby reducing the jamming at the point where the detection rod 601 contacts the quartz tube and improving the adjustment accuracy and efficiency.

[0120] Example 8:

[0121] This embodiment provides a quartz carrier welding fixture, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the tube pressing mechanism 5 includes:

[0122] The second support frame 51 is installed on the processing platform 2 and is equipped with a second drive unit 52;

[0123] The support plate 53 is slidably mounted on the second support frame 51 and is driven to rise and fall by the second drive unit 52;

[0124] The pressure plate 54 is connected to the second support frame 51 via the adjusting component 50, and the pressure plate 54 is rotatably connected to the adjusting component 50.

[0125] The pressure plate 54 and the output end of the adjustment component 50 can be connected by bearings.

[0126] As can be seen from this embodiment, the second drive unit 52 drives the pressure plate 54 to rise and fall, which can adapt to quartz tubes of different heights and improve applicability. Furthermore, the pressure plate 54 adopts a rotating connection, that is, when welding between the quartz tube and the quartz flange, after the local welding is fixed, when the rotary table 3 starts to rotate, it is not necessary to lift the pressure plate 54, thus avoiding the quartz tube from tilting and ensuring the welding quality.

[0127] Example 9:

[0128] This embodiment provides a quartz carrier welding fixture, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the adjustment component 50 includes:

[0129] The third drive unit 500 is mounted on the support plate 53 and is used to drive the pressure plate 54 to move along the X-axis.

[0130] The fourth drive unit 501 is installed at the output end of the third drive unit 500 and is used to drive the pressure plate 54 to move along the Y-axis.

[0131] As can be seen from this embodiment, the third drive unit 500 and the fourth drive unit 501 facilitate the correction of the tilted quartz tube by contacting the top of the quartz tube and then slowly moving it, thereby improving automation and increasing the accuracy and efficiency of the correction.

[0132] Example 10:

[0133] This embodiment provides a welding process for a quartz carrier welding fixture, including the following steps:

[0134] S1: Power on;

[0135] S2: According to the required diameter / radius of the quartz flange to be welded, refer to the scale 44 and adjust the adjusting screw 43 to the appropriate position;

[0136] S2: Place the quartz flange in the mounting groove 41 of the limiting plate 4 and tighten the adjusting screw 43;

[0137] S3: Place the quartz tube on the quartz flange and fix the quartz tube by pressing down the tube pressing mechanism 5;

[0138] S4: Testing agency 6 checks whether the quartz tube is tilted and provides feedback;

[0139] S5: Based on the feedback from the detection mechanism 6, the quartz tube is moved by the adjustment component 50 to make it perpendicular to the quartz flange;

[0140] S6: The quartz flange and quartz tube are rotated simultaneously by the rotary table 3, and the welding gun mechanism is used to weld the contact point between the two.

[0141] Specifically:

[0142] In the above S4, the first drive unit 600 pushes the first support frame 611 to move towards the limiting plate 4. When the two detection rods 601 abut against the surface of the quartz tube, they will compress the spring 602 and drag the slider 606 to move on the slide rail 605. The ranging unit 608 detects and compares the movement of the two detection rods 601. When there is a difference, it is determined that there is a tilt, and feedback is given on the tilt in the X-axis or Y-axis respectively.

[0143] In the above S5, the third drive unit 500 and the fourth drive unit 501 are adjusted by detecting the X-axis or Y-axis. During the adjustment, the ranging unit 608 provides real-time feedback until the values ​​measured by the two detection rods 601 in the X-axis and the two detection rods 601 in the Y-axis are the same (measurement error is allowed, so a value range needs to be set and preset. When the difference between the data measured by the two detection rods 601 in the same direction is within the value range, the two values ​​are considered to be the same). That is, it is determined that the quartz tube is perpendicular to the quartz flange, and then welding is performed.

[0144] As can be seen from this embodiment, the above welding process can effectively detect and correct the tilting of the quartz tube in a timely manner. Then, the welding gun mechanism is used to weld the connection between the two, which effectively ensures the product quality of the quartz tube and avoids the possibility of cracks due to excessive local tensile force on the connection of the quartz flange during subsequent use. Furthermore, the tooling can correct the tilting itself, improving accuracy and efficiency.

[0145] The first drive unit 600, the second drive unit 52, the third drive unit 500, and the fourth drive unit 501 mentioned in the above embodiments are all composed of slide rail 605, slider 606, lead screw transmission mechanism, motor, etc., which are all prior art and will not be described in detail here.

[0146] The embodiments of this application have been described above with reference to the accompanying drawings.
