Description

Technical Field

[0001] This invention relates to the field of machining technology, and in particular to a device for machining irregular quartz features on a spinning machine. Background Technology

[0002] When machining features on quartz tubes using a spinning machine, such as bevels, radius angles, and W-shaped curvatures, the current method involves clamping the tube material onto the chuck of the spinning machine, heating the machining area using hydrogen-oxygen welding, then manually controlling a graphite fixture to approach the heated area and gradually shape it. The machining quality is initially controlled by visually observing the undulations of the feature area while the spinning machine is rotating, and finally, the quality is determined by checking the gauges after the machine stops.

[0003] For example, publication number "CN118720540A" discloses "an arc plate tail tube docking device," which includes a spinning machine and an arc plate fixing fixture mounted on the spinning machine. The arc plate fixing fixture includes a first fixing part connected to the spinning machine and a first clamping part for clamping the quartz arc plate. A tail tube fixing fixture is provided on the other side of the first clamping part. The tail tube fixing fixture includes a second clamping part and a second fixing part for clamping the quartz tail tube. The second fixing part is provided with a pushing part to clamp or release the second clamping part. However, in practical applications, when machining features such as bevels on quartz tubes on a spinning machine, manual positioning of the graphite fixture is still required, resulting in poor machining accuracy. Summary of the Invention

[0004] In view of the problem mentioned in the background art that the existing technology has poor accuracy when processing quartz tubes using a spinning machine, the present invention provides a quartz irregular feature processing device for a spinning machine, which can improve the accuracy when processing features such as bevel angles, R angles, and W-shaped arcs of quartz tubes, improve the positioning accuracy and stability of the graphite fixture during the processing, and improve the convenience of operation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] A quartz irregular shape feature processing device for a spinning machine includes a support plate slidably connected to the spinning machine. A lower base plate is provided on the support plate, and a lifting linkage assembly is connected to the lower base plate. The lifting linkage assembly includes a hinge unit, which includes several driving hinge points. Each driving hinge point is rotatably connected to a crossbar unit, which is connected to a lead screw unit. Rotation of the lead screw unit can drive the crossbar unit to produce axial displacement relative to the lead screw unit. An upper top plate is connected to the hinge unit, and a processing fixture is provided on the upper top plate. In the prior art, when processing features on quartz tube products such as different angled bevels, different radius angles, and W-shaped curvatures using a spinning machine, the tube material is currently clamped in the chuck of the spinning machine, and the processing area is heated using oxyhydrogen welding. Then, a graphite fixture is manually controlled to approach the heated area and gradually form the shape. The processing quality is initially controlled by visually observing the undulations of the feature area while the spinning machine is rotating. Finally, the quality is determined by measuring instruments after the machine stops. The processing quality (dimensional dimensions) of the beveled, rounded, and W-shaped features on the product is controlled solely by manually adjusting the fixture. After the machine stops, the dimensions are self-checked with measuring tools and then corrected based on the self-check results. This process is inconvenient, time-consuming, and labor-intensive, and the dimensions are difficult to guarantee. The beveled and rounded angles vary depending on the product, and customizing individual fixtures is costly and not convenient for unified on-site management. Therefore, to address the aforementioned problems, this application places a graphite jig (machining jig) on ​​an upper top plate. A lifting linkage assembly is provided between the upper top plate and the lower bottom plate. This lifting linkage assembly is capable of vertical displacement and contains several hinge units. Each hinge unit has a rod-like structure, and hinge points are formed between them. These hinge points are rotatably connected to the crossbar assembly. The hinge units and the crossbar units are perpendicularly connected. The crossbar units achieve displacement through connecting screw units. Rotation of the screw unit can cause displacement of the crossbar units connected to it, creating a self-locking mechanism to ensure stability between the upper top plate and the lower bottom plate. A machining jig is provided on the upper top plate. The processing fixture is a graphite fixture. The quartz irregular feature processing device is placed on a spinning machine. During the processing, the quartz tube is first placed on the jaws of the spinning machine for fixation. The quartz irregular feature processing device is moved to a position close to the quartz tube by the guide rail on the spinning machine, so that the processing fixture contacts the quartz tube. Then, the irregular feature is processed. During the processing, the screw unit can self-lock the crossbar unit, thus ensuring the stability of the processing fixture and improving its adaptability to the processing of irregular features. Furthermore, the rotation of the screw unit can drive the lifting linkage assembly to move up and down, thereby improving the adaptability of the processing fixture to the processing of different irregular features.

[0007] Preferably, the processing fixture includes a mounting base, within which a fixture unit is detachably connected. This detachable connection between the mounting base and the fixture unit facilitates subsequent adaptability replacement of the fixture unit, thereby enabling processing of various irregularly shaped features.

[0008] Preferably, the mounting base is provided with a lateral fixing position and a longitudinal fixing position, and fixing bolts are connected to both the lateral and longitudinal fixing positions. Lateral and longitudinal fixing positions are respectively provided on both sides of the mounting base, and threaded holes are provided on both the lateral and longitudinal fixing positions. Fixing bolts are connected to the threaded holes, and the fixing bolts can pass through the threaded holes and abut against the fixture unit connected inside the mounting base, thereby fixing and limiting the fixture unit and ensuring the reliability of the connection between the fixture unit and the mounting base.

[0009] Preferably, the lifting linkage assembly includes a first unit and a second unit. The first unit includes a first main crossbar, and the second unit includes a second main crossbar. The lead screw unit includes a lead screw portion and an axial fixing portion. The axial fixing portion is rotatably connected to the second main crossbar, and the lead screw portion is threadedly connected to the first main crossbar. The lifting linkage assembly consists of two parts, namely the first unit and the second unit. The first unit includes the first main crossbar, and the second unit includes the second main crossbar. The first and second main crossbars are arranged close to each other. The lead screw portion is connected to the first main crossbar, and the axial fixing portion is connected to the second main crossbar. The entire lead screw unit includes a lead screw portion and an axial fixing portion. During the rotation of the lead screw unit, the axial fixing portion and the lead screw portion rotate synchronously. The difference is that the axial fixing portion is only rotatably connected to the second main crossbar; the axial fixing portion cannot be directly connected to the second main crossbar. Axial displacement occurs between them; and the lead screw and the first main crossbar are connected by a thread, so during operation, when the lead screw unit rotates, the axial direction of the lead screw unit remains unchanged with respect to the second crossbar. The first main crossbar and the lead screw unit undergo relative axial displacement, which is synchronously driven by the upper top plate and the lower bottom plate to move the first unit and the second unit up and down. During the up and down displacement of the upper top plate, the first main crossbar and the second main crossbar move up and down synchronously, and the lead screw unit also moves up and down synchronously, keeping in line with the first main crossbar and the second main crossbar.

[0010] Preferably, the lifting linkage assembly includes several linkage units, each with a main crossbar and a secondary crossbar. A guide shaft, connecting both the main and secondary crossbars, is also provided within the same linkage unit. The guide shaft connects to the main crossbar in an adjacent linkage unit. Within the same linkage unit, the guide shaft connects to both the main and secondary crossbars, and also to the main crossbar in an adjacent linkage unit. This allows each guide shaft to connect two main crossbars and one secondary crossbar simultaneously. The guide shaft provides guidance for the movement of the linkage units and assists in the synchronous movement between the linkage units, improving the accuracy and synchronicity of the movements.

[0011] Preferably, a rotating disk is provided on the upper end of the lead screw unit, and a rotating handle is connected to the rotating disk. Through the rotational connection between the rotating handle and the rotating disk, the rotating handle can remain stationary while the rotating disk rotates during the rotation of the lead screw unit, thereby improving operational convenience.

[0012] Preferably, the upper top plate is provided with a universal adjustment seat, which includes an arc-shaped slide rail. A processing fixture is slidably connected to the arc-shaped slide rail, and the processing fixture includes a processing part for processing quartz tubes. When the processing fixture slides on the arc-shaped slide rail, it rotates around the processing part. A universal adjustment seat is also provided on the upper bottom plate, which includes an arc-shaped slide rail. The arc-shaped slide rail is an upwardly extending arc structure. The processing fixture is slidably connected to the arc-shaped slide rail. The part of the processing fixture that contacts the quartz tube is the processing part. When the processing fixture slides on the arc-shaped slide rail, it can rotate around the processing part, that is, the center of the arc-shaped slide rail coincides with the position of the processing part. This allows the processing fixture to generate a circular motion around the processing part when it moves on the arc-shaped slide rail. Since the graphite fixture needs to process the inclined surface, arc surface, etc., of the quartz tube, the required inclination angle for different quartz tubes varies, necessitating adjustment of the graphite fixture's inclination angle. Furthermore, when quartz tubes require multi-stage processing, the tilt angle of the graphite fixture needs to be constantly adjusted. If the graphite fixture inside the processing fixture is replaced each time, it will increase the adjustment time significantly and raise the reserve cost of the graphite fixture. Therefore, in this application, the processing fixture is installed on an arc slide rail, so that the tilt angle of the processing part of the graphite fixture can be changed when the processing fixture moves along the arc slide rail. This allows the graphite fixture to adapt to processing requirements with different tilt angles, and the angle adjustment is more convenient. Moreover, the same graphite fixture can be used for processing, avoiding the need for frequent disassembly and adjustment of the processing fixture.

[0013] Preferably, the universal adjustment seat includes a base, which is rotatably connected to an upper top plate. The rotation axis of the base is perpendicular to the rotation axis of the machining fixture. Because the base is rotatably connected to the upper top plate, the base can drive the arc-shaped slide rail to rotate synchronously during rotation. This allows the graphite fixture inside the machining fixture to perform circular motion around the rotation center of the base, enabling the fixture to achieve circular motion in two directions. The angle adjustment in these two directions allows for more comprehensive adjustment of the fixture's tilt angle, improving its adaptability. Furthermore, when the machining section of the quartz tube is in a non-end position, multi-directional rotation can avoid interference risks on both sides of the machining section and adjust the tilt angle to meet machining standards.

[0014] Preferably, an inner arc block and an outer arc block are connected to both sides of the arc slide rail. The inner arc block is connected to a processing fixture, and a fastening bolt is connected to the outer arc block. The fastening bolt passes through the arc slide rail and connects to the inner arc block. The machining fixture is installed inside the arc-shaped slide rail via inner and outer arc blocks. The inner arc block is located on the side of the slide rail closer to the inner ring, and the outer arc block is located on the side closer to the outer ring. Fastening bolts on the outer arc block can pass through the inner arc block and connect to it, allowing the inner and outer arc blocks to slide synchronously. When the fastening bolts are loosened, the inner and outer arc blocks can move relative to the slide rail, thereby changing the tilt angle of the machining fixture. When the fastening bolts are tightened, they can clamp and secure the slide rail, thus limiting the position of the machining fixture relative to the slide rail and fixing it at the target position on the slide rail, ensuring the stability and adjustability of the machining fixture.

[0015] Preferably, the processing fixture includes a mounting base with a mounting groove. A fixture unit is detachably connected to the mounting groove. The fixture unit includes an eccentric counterweight located in the mounting groove. A locking shaft is connected to the mounting base. An adjusting screw is provided on the side of the mounting base near the eccentric counterweight. The eccentric counterweight includes an adjusting inclined surface that abuts against the adjusting screw. The machining fixture consists of a mounting base and a fixture unit, which is a graphite fixture. The fixture unit is installed in a mounting slot, the size of which is larger than the size of the fixture unit, allowing the fixture unit to move relative to the mounting slot. The fixture unit is not a symmetrical structure; it contains an eccentric counterweight, giving the fixture unit an overall "L" shape. Without external force limiting its movement, the eccentric counterweight cannot remain horizontal. Therefore, an adjusting screw is installed on the mounting base. This adjusting screw can be adjusted relative to the mounting base, and it abuts against an adjusting ramp on the eccentric counterweight. Initially, the adjusting screw abuts against the adjusting ramp, keeping the eccentric counterweight horizontal. However, because the eccentric counterweight is eccentrically positioned, it always has a downward tendency to move. As the adjusting screw moves outward... When disengaged, the eccentric counterweight moves gradually downwards along the adjusting ramp. Since the fixture unit is connected to the mounting base via a locking shaft, the fixture unit can rotate relative to the locking shaft when it is loose. When the locking shaft is tightened, it causes the mounting groove to squeeze the fixture unit, thus securing and locking the fixture unit inside the mounting groove to prevent rotation. The eccentric counterweight allows the fixture unit to rotate automatically under gravity during the adjustment screw's operation, improving the convenience and accuracy of adjustment. When the eccentric counterweight is combined with the arc slide rail, the inclination of the adjusting ramp is small, resulting in a small range of motion of the entire fixture unit caused by the eccentric counterweight when the adjusting screw is moved, producing a fine-tuning effect. The main angle adjustment is achieved by machining the fixture's displacement on the arc slide rail, ensuring the accuracy of the adjustment.

[0016] The beneficial effects of this invention are as follows: (1) The rotation of the lead screw unit drives the lifting linkage assembly to move up and down, thereby enabling the machining fixture to improve its adaptability when dealing with different irregular features. (2) The guide shaft provides guidance for the movement of the linkage unit and can assist the synchronous movement between the linkage units, thereby improving the accuracy and synchronicity of the movement; (3) The machining fixture is installed on the arc slide rail, so that when the machining fixture moves along the arc slide rail, the tilt angle of the graphite fixture machining part can be changed, so that the graphite fixture can adapt to the machining requirements of different tilt angles. (4) The fixture can achieve circular motion in two directions. The angle adjustment in the two circular directions can make the tilt angle adjustment of the fixture more comprehensive and improve its adaptability. (5) By setting the eccentric counterweight, the fixture unit can be automatically driven to rotate by gravity during the adjustment screw operation, which improves the convenience and accuracy of adjustment.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1: like Figure 1 ,2As shown in the figure, a processing device for the special-shaped features of quartz in a lathe includes a platen 11 slidably connected to the lathe. A lower base plate 12 is provided on the platen 11, and a lifting link assembly 2 is connected to the lower base plate 12. The lifting link assembly 2 includes a hinge rod unit 21, and the hinge rod unit 21 includes a number of driving articulated points 22. A cross-bar unit 23 is rotatably connected to the driving articulated point 22. The cross-bar unit 23 is connected to a screw rod unit 3. When the screw rod unit 3 rotates, it can cause the cross-bar unit 23 to generate an axial displacement relative to the screw rod unit 3. An upper top plate 13 is connected to the hinge rod unit 21, and a processing fixture 4 is provided on the upper top plate 13. In the prior art, when processing features such as bevels at different angles, R corners at different angles, and W-shaped arcs on quartz tube products with a lathe, currently, the tube material is clamped on the chuck of the lathe, and the processing part 43 is heated by hydrogen-oxygen welding. Then, the graphite fixture is manually controlled to approach the heating part and gradually formed. The processing quality is initially controlled by visually observing the undulation of the feature part under the rotating state of the lathe, and finally, it is judged whether it is qualified by checking with a measuring tool after stopping the machine. The processing quality (outer dimension) of the bevel, R corner, and W-shaped feature parts on the product is only controlled by manually adjusting the fixture. After stopping the machine, it is self-checked with a measuring tool and then corrected according to the self-check result. The operation is inconvenient and time-consuming, and the outer dimension is not easy to ensure; for bevels and R corners, there are different angular dimensions according to different products, and the cost of customizing a single fixture is relatively high, and it is not convenient for on-site unified management. Therefore, in view of the above problems, in this application, the graphite fixture (processing fixture 4) is placed on the upper top plate 13. A lifting link assembly 2 is provided between the upper top plate 13 and the lower base plate 12. The lifting link assembly 2 can perform lifting displacement. There are a number of hinge rod units 21 on the lifting link assembly 2. The hinge rod unit 21 is a rod-shaped structure. Articulated points are formed between the respective hinge rod units 21. The connection between the joint point and the cross-bar assembly is a rotational connection. The connection relationship between the hinge rod unit 21 and the cross-bar unit 23 is perpendicular to each other. The cross-bar unit 23 realizes displacement through the connected screw rod unit 3. When the screw rod unit 3 rotates, it can cause the cross-bar unit 23 connected to the screw rod unit 3 to generate displacement and form self-locking, ensuring the stability between the upper top plate 13 and the lower base plate 12; a processing fixture 4 is provided on the upper top plate 13, and the processing fixture 4 is a graphite fixture. The processing device for the special-shaped features of quartz is placed on the lathe. During the processing, first, the quartz tube is placed on the jaws of the lathe for fixation. The processing device for the special-shaped features of quartz is moved to a position close to the quartz tube through the guide rail on the lathe, so that the processing fixture 4 contacts the quartz tube. Subsequently, the special-shaped features are processed. During the processing, since the screw rod unit 3 can lock the cross-bar unit 23, the stability of the processing fixture 4 can be ensured, the adaptability for processing special-shaped features can be improved, and the lifting link assembly 2 can be driven to perform up and down displacement by the rotation of the screw rod unit 3, so that the processing fixture 4 can improve the adaptability when dealing with different special-shaped feature processing.

[0027] like Figure 5 As shown, the machining fixture 4 includes a mounting base 41, and a fixture unit 42 is detachably connected to the mounting base 41. The detachable connection between the mounting base 41 and the fixture unit 42 facilitates subsequent adaptation and replacement of the fixture unit 42, thereby enabling it to adapt to machining operations of different irregular features.

[0028] like Figure 5 As shown, the mounting base 41 is provided with a transverse fixing position 412 and a longitudinal fixing position 413, and fixing bolts are connected to both the transverse fixing position 412 and the longitudinal fixing position 413. A transverse fixing position 412 and a longitudinal fixing position 413 are respectively provided on both the transverse and longitudinal sides of the mounting base 41. Threaded holes are provided on the transverse fixing position 412 and the longitudinal fixing position 413, and fixing bolts are connected to the threaded holes. The fixing bolts can pass through the threaded holes and abut against the fixture unit 42 connected inside the mounting base 41, thereby fixing and limiting the fixture unit 42 and ensuring the reliability of the connection between the fixture unit 42 and the mounting base 41.

[0029] like Figure 3As shown, the lifting linkage assembly 2 includes a first unit 24 and a second unit 25. The first unit 24 includes a first main crossbar 241, and the second unit 25 includes a second main crossbar 251. The lead screw unit 3 includes a lead screw part 31 and an axial fixing part 32. The axial fixing part 32 is rotatably connected to the second main crossbar 251, and the lead screw part 31 is threadedly connected to the first main crossbar 241. The lifting linkage assembly 2 consists of two parts: a first unit 24 and a second unit 25. The first unit 24 includes a first main crossbar 241, and the second unit 25 includes a second main crossbar 251. The first and second main crossbars 241 and 251 are arranged close to each other. A lead screw portion 31 is connected to the first main crossbar 241, and an axial fixing portion 32 is connected to the second main crossbar 251. The entire lead screw unit 3 includes a lead screw portion 31 and an axial fixing portion 32. During the rotation of the lead screw unit 3, the axial fixing portion 32 and the lead screw portion 31 rotate synchronously. However, the axial fixing portion 32 is only rotatably connected to the second main crossbar 251; the axial fixing portion 32 cannot be... An axial displacement occurs between the first main crossbar 241 and the second main crossbar 251. The lead screw 31 is threadedly connected to the first main crossbar 241. Therefore, during operation, when the lead screw unit 3 rotates, the axial direction of the lead screw unit 3 remains unchanged relative to the second crossbar. The first main crossbar 241 and the lead screw unit 3 undergo relative axial displacement. The first unit 24 and the second unit 25 are driven to move up and down synchronously through the upper top plate 13 and the lower bottom plate 12. During the up and down movement of the upper top plate 13, the first main crossbar 241 and the second main crossbar 251 move up and down synchronously, and the lead screw unit 3 also moves up and down synchronously, keeping in line with the first main crossbar 241 and the second main crossbar 251.

[0030] like Figure 4 As shown, the lifting linkage assembly 2 includes several linkage units 26. Each linkage unit 26 contains a main crossbar 261 and a secondary crossbar 262. A guide shaft 263 is provided within the same linkage unit 26, simultaneously connecting the main crossbar 261 and the secondary crossbar 262. The guide shaft 263 is connected to the main crossbar 261 in the adjacent linkage unit 26. Within the same linkage unit 26, the guide shaft 263 is simultaneously connected to both the main crossbar 261 and the secondary crossbar 262, and also to the main crossbar 261 in the adjacent linkage unit 26. This allows each guide shaft 263 to simultaneously connect two main crossbars 261 and one secondary crossbar 262. The guide shaft 263 provides guidance for the movement of the linkage units 26 and assists in the synchronous movement between the various linkage units 26, improving the accuracy and synchronicity of the movements.

[0031] like Figure 1As shown, a rotating disk 5 is provided on the upper end of the lead screw unit 3, and a rotating handle 51 is connected to the rotating disk 5. Through the rotational connection between the rotating handle 51 and the rotating disk 5, the rotating handle 51 can be kept stationary while the rotating disk 5 is rotated during the rotation of the lead screw unit 3, thereby improving the convenience of operation.

[0032] Example 2: like Figure 6 As shown, a quartz irregular feature processing device for a spinning machine includes a support plate 11 slidably connected to the spinning machine, a lower base plate 12 provided on the base 62, a lifting linkage assembly 2 connected to the lower base plate 12, the lifting linkage assembly 2 including a hinge unit 21, the hinge unit 21 including a plurality of drive hinge points 22, the drive hinge points 22 are rotatably connected to a crossbar unit 23, the crossbar unit 23 is connected to a lead screw unit 3, the rotation of the lead screw unit 3 can drive the crossbar unit 23 to generate an axial displacement relative to the lead screw unit 3, an upper top plate 13 is connected to the hinge unit 21, and a processing fixture 4 is provided on the upper top plate 13. A universal adjustment seat 6 is provided on the top plate 13. The universal adjustment seat 6 includes an arc slide rail 61. A processing fixture 4 is slidably connected to the arc slide rail 61. The processing fixture 4 includes a processing part 43 for processing quartz tubes. When the processing fixture 4 slides on the arc slide rail 61, the processing fixture 4 rotates around the processing part 43.

[0033] A universal adjustment seat 6 is provided on the upper base plate. The universal adjustment seat 6 includes an arc slide rail 61, which is an upwardly extending arc structure. The machining fixture 4 is slidably connected to the arc slide rail 61. The part of the machining fixture 4 that contacts the quartz tube is the machining part 43. When the machining fixture 4 slides on the arc slide rail 61, it can rotate around the machining part 43, that is, the center position of the arc slide rail 61 coincides with the position of the machining part 43. This allows the machining fixture 4 to generate a circular motion around the machining part 43 when it moves on the arc slide rail 61. Since the graphite fixture needs to process the inclined surface, arc surface, etc. of the quartz tube, the inclination degree required for the irregular structural features of different quartz tubes is not the same. Therefore, the graphite fixture needs to be adjusted accordingly. The tilt angle needs to be adjusted, and when the quartz tube needs to be processed in multiple stages, the tilt angle of the graphite fixture needs to be adjusted continuously. If the graphite fixture in the processing fixture 4 is replaced every time, it will increase the adjustment time and increase the reserve cost of the graphite fixture. Therefore, in this application, the processing fixture 4 is installed on the arc slide rail 61, so that when the processing fixture 4 moves along the arc slide rail 61, the tilt angle of the graphite fixture processing part 43 can be changed, so that the graphite fixture can adapt to the processing requirements of different tilt angles, and the angle adjustment is more convenient. Moreover, the same graphite fixture can be used for processing, avoiding the need to frequently disassemble and adjust the processing fixture 4.

[0034] like Figure 6As shown, the universal adjustment seat 6 includes a base 62, which is rotatably connected to the upper top plate 13. The rotation axis of the base 62 is perpendicular to the rotation axis of the machining fixture 4. The base 62 of the universal adjustment seat 6 is rotatably connected to the upper top plate 13. Because the base 62 is rotatably connected to the upper top plate 13, the base 62 can drive the arc slide rail 61 to rotate synchronously during rotation. This allows the graphite fixture inside the machining fixture 4 to perform circular motion around the rotation center of the base 62, enabling the fixture to achieve circular motion in two directions. The angle adjustment in these two directions allows for more comprehensive adjustment of the fixture's tilt angle, improving its adaptability. The upper top plate 13 is equipped with a rotating shaft. The base 62 is fitted onto the rotating shaft, and bolts are connected to the rotating shaft. After loosening the bolts, the base can rotate around the rotating shaft. After rotating to a specified angle, the bolts are tightened to fix and lock the base 62 relative to the rotating shaft.

[0035] like Figure 6 As shown, an inner arc block 611 and an outer arc block 612 are connected to both sides of the arc slide rail 61. The inner arc block 611 is connected to the processing fixture 4, and a fastening bolt 613 is connected to the outer arc block 612. The fastening bolt 613 passes through the arc slide rail 61 and is connected to the inner arc block 611. The machining fixture 4 is installed inside the arc slide rail 61 via an inner and outer arc block. The inner arc block is located on the side of the arc slide rail 61 closer to the inner ring, and the outer arc block is located on the side of the arc slide rail 61 closer to the outer ring. The fastening bolt 613 on the outer arc block can pass through the inner arc block and connect with it, allowing the inner and outer arc blocks to slide synchronously. When the fastening bolt 613 is loosened, the inner and outer arc blocks can move relative to the arc slide rail, thereby changing the tilt angle of the machining fixture 4. When the fastening bolt 613 is tightened, it can drive the inner and outer arc blocks to clamp and tighten the arc slide rail 61, thereby allowing the machining fixture 4 to be positioned relative to the arc slide rail and fixed at the target position on the arc slide rail, ensuring the stability and adjustability of the machining fixture 4.

[0036] Example 3: like Figure 7As shown, a quartz irregular feature processing device for a spinning machine includes a support plate 11 slidably connected to the spinning machine, a lower base plate 12 provided on the base 62, a lifting linkage assembly 2 connected to the lower base plate 12, the lifting linkage assembly 2 including a hinge unit 21, the hinge unit 21 including a plurality of drive hinge points 22, the drive hinge points 22 are rotatably connected to a crossbar unit 23, the crossbar unit 23 is connected to a lead screw unit 3, the rotation of the lead screw unit 3 can drive the crossbar unit 23 to generate an axial displacement relative to the lead screw unit 3, an upper top plate 13 is connected to the hinge unit 21, and a processing fixture 4 is provided on the upper top plate 13. The machining fixture 4 includes a mounting base 41, a mounting groove 411 on the mounting base 41, a fixture unit 42 detachably connected in the mounting groove 411, the fixture unit 42 includes an eccentric counterweight 421 located in the mounting groove 411, a locking shaft 414 connected to the mounting base 41, an adjusting screw 44 on the side of the mounting base 41 near the eccentric counterweight 421, and the eccentric counterweight 421 includes an adjusting inclined surface 422 that abuts against the adjusting screw 44.

[0037] The machining fixture 4 consists of a mounting base 41 and a fixture unit 42, wherein the fixture unit 42 is a graphite fixture. The fixture unit 42 is installed in a mounting groove 411, the size of which is larger than the size of the fixture unit 42, allowing the fixture unit 42 to move relative to the mounting groove 411. The fixture unit 42 is not a symmetrical structure; it contains an eccentric counterweight 421, giving the fixture unit 42 an overall "L" shape. Without external force limiting its movement, the eccentric counterweight 421 cannot be kept horizontal. Therefore, an adjusting screw 44 is provided on the mounting base 41. The adjusting screw 44 can be adjusted relative to the mounting base 41, and it abuts against the adjusting inclined surface 422 on the eccentric counterweight 421. Initially... In this state, the adjusting screw 44 abuts against the adjusting ramp 422, so that the eccentric counterweight 421 can be kept on the horizontal water surface. Since the eccentric counterweight 421 is eccentrically set, the eccentric counterweight 421 will always have a downward tendency. As the adjusting screw 44 is continuously pulled outward, the eccentric counterweight 421 will gradually move downward along the adjusting ramp 422. Since the fixture unit 42 is connected to the mounting base 41 through the locking shaft 414, when the locking shaft 414 is loose, the fixture unit 42 can rotate relative to the locking shaft 414. When the locking shaft is tightened, it drives the mounting groove 411 to squeeze the fixture unit 42, thereby making the fixture unit 42 securely constrained and locking the fixture unit 42 inside the mounting groove 411 to prevent rotation.

[0038] Example 4: like Figure 6 , 7As shown, a quartz tube irregular feature processing device for a spinning machine includes a support plate 11 slidably connected to the spinning machine, a lower base plate 12 on a base 62, a lifting linkage assembly 2 connected to the lower base plate 12, the lifting linkage assembly 2 including a hinge unit 21, the hinge unit 21 including a plurality of drive hinge points 22, the drive hinge points 22 being rotatably connected to a crossbar unit 23, the crossbar unit 23 being connected to a lead screw unit 3, the rotation of the lead screw unit 3 being able to drive the crossbar unit 23 to produce an axial displacement relative to the lead screw unit 3, an upper top plate 13 connected to the hinge unit 21, and a processing fixture 4 provided on the upper top plate 13. A universal adjustment seat 6 is provided on the upper top plate 13, the universal adjustment seat 6 including an arc slide rail 61, the processing fixture 4 being slidably connected to the arc slide rail 61, the processing fixture 4 including a processing part 43 for processing quartz tubes, when the processing fixture 4 slides on the arc slide rail 61, the processing fixture 4 rotates around the processing part 43. The machining fixture 4 includes a mounting base 41 with a mounting groove 411. A fixture unit 42 is detachably connected to the mounting groove 411. The fixture unit 42 includes an eccentric counterweight 421 located within the mounting groove 411. A locking shaft 414 is connected to the mounting base 41. An adjusting screw 44 is provided on the side of the mounting base 41 near the eccentric counterweight 421. The eccentric counterweight 421 includes an adjusting inclined surface 422 that abuts against the adjusting screw 44. An inner arc block 611 and an outer arc block 612 are respectively connected to both sides of the arc slide rail 61. The inner arc block 611 is connected to the machining fixture 4, and a fastening bolt 613 is connected to the outer arc block 612. The fastening bolt 613 passes through the arc slide rail 61 and connects to the inner arc block 611. The universal adjustment seat 6 includes a base 62, which is rotatably connected to the top plate 13. The rotation axis of the base 62 is perpendicular to the rotation axis of the machining fixture 4.

[0039] The processing fixture 4 consists of a mounting base 41 and a fixture unit 42. The fixture unit 42 is a graphite fixture, installed in a mounting groove 411. The size of the mounting groove 411 is larger than the size of the fixture unit 42, allowing the fixture unit 42 to move relative to the mounting groove 411. The fixture unit 42 is not a symmetrical structure; it contains an eccentric counterweight 421, giving the fixture unit 42 an overall "L" shape. Without external force limiting its position, the eccentric counterweight 421 cannot be kept horizontal. Therefore, an adjusting screw 44 is provided on the mounting base 41. The adjusting screw 44 can be adjusted relative to the mounting base 41, and it abuts against the adjusting ramp 422 on the eccentric counterweight 421. In the initial state, the adjusting screw 44 abuts against the adjusting ramp 422, allowing the eccentric counterweight 421 to be kept horizontal. However, because the eccentric counterweight 421 is eccentrically positioned, ... This eccentric counterweight 421 will always have a downward tendency. As the adjusting screw 44 continuously disengages outward, the eccentric counterweight 421 will gradually move downward along the adjusting ramp 422. Since the fixture unit 42 is connected to the mounting base 41 via the locking shaft 414, the fixture unit 42 can rotate relative to the locking shaft 414 when the locking shaft 414 is loose. When the locking shaft is tightened, it causes the mounting groove 411 to press against the fixture unit 42, thereby... The fixture unit 42 is fastened and constrained, locking the fixture unit 42 inside the mounting groove 411 to prevent rotation. When the eccentric counterweight 421 is combined with the arc slide rail 61, the inclination of the adjusting slope 422 is set to be small, so that when the adjusting screw 44 is moved, the eccentric counterweight 421 drives the overall fixture unit 42 to move a small range, producing a fine adjustment effect. The main angle adjustment is achieved by the displacement of the machining fixture 4 on the arc slide rail 61, ensuring the accuracy of the adjustment.
