Technical Field

[0001] This invention belongs to the field of quartz tube cutting technology, specifically a quartz tube cutting device. Background Technology

[0002] Quartz tubes are a special type of industrial glass made from silicon dioxide. Due to their excellent high-temperature resistance, corrosion resistance, high thermal stability, and superior optical and electrical properties, they are widely used in high-tech and industrial fields such as semiconductors, photovoltaics, optics, electric light sources, and heating equipment. Current technologies for cutting quartz tubes involve automatic or semi-automatic arc or metal cutting, specifically laser cutting or a cutting saw. While both methods can achieve high-precision processing, they have the following drawbacks: Existing cutting equipment does not have the function of deburring the surface of the tube opening. After cutting the quartz tube, it is necessary to transport the cut quartz tube to a special deburring equipment for deburring treatment, which reduces processing efficiency. Moreover, transporting the quartz tube requires more manpower and resources, which increases costs. Summary of the Invention

A synchronous belt assembly is connected between the long rotating rod and the grinding cylinder. The side of the grinding cylinder facing the quartz tube and the side facing away from the quartz tube are both grinding surfaces.

[0016] 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.

[0017] like Figures 1 to 8As shown, the present invention provides a quartz tube cutting device, including a worktable 1. Three rubber wheel frames 101 are arranged side-by-side in the middle of the worktable 1. The rubber wheel frames 101 support the bottom of the quartz tube 102 to be processed. Each rubber wheel frame 101 consists of a mounting frame and multiple rubber wheels rotatably sleeved on the mounting frame. The two ends of the mounting frame are fixedly connected to the surface of the worktable 1. In this embodiment, preferably, the mounting frame is a telescopic frame, capable of vertical extension and retraction adjustment, and can be fixed at the adjusted height after extension and retraction adjustment. The telescopic design of the mounting frame adapts to support quartz tubes 102 of different diameters. A short support plate 103 is fixedly connected to one end of the workbench 1. A telescopic rod 104 is fixedly connected to the short support plate 103. A rubber hard disk 105 is rotatably connected to the movable end of the telescopic rod 104. The end of the rubber hard disk 105 facing away from the telescopic rod 104 is used to engage with the quartz tube 102. Specifically, the side of the rubber hard disk 105 facing the quartz tube 102 has multiple annular grooves of different diameters to accommodate tubes of different diameters. By engaging one end of the quartz tube 102 into the annular grooves in the rubber hard disk 105, a fixed connection between the quartz tube 102 and the rubber hard disk 105 is achieved. A laser cutter 106 is provided on the workbench 1 for cutting the quartz tube 102 into segments.

[0018] The above solution is adopted: such as Figure 1 As shown, by inserting one end of the quartz tube 102 into the annular groove in the rubber hard disk 105 for limiting and locking, the middle part of the quartz tube 102 is placed on the rubber wheel frame 101, and the bottom surface of the quartz tube 102 is in contact with the rubber wheel on the rubber wheel frame 101. Then, the telescopic rod 104 fixed on the short support plate 103 is activated, so that the movable end of the telescopic rod 104 extends and drives the rubber hard disk 105 and the quartz tube 102 to move synchronously.

[0019] A grinding cylinder 206 is rotatably connected to the end of the worktable 1 away from the short support plate 103. The end of the quartz tube 102 away from the rubber hard disk 105 can fit against the wall of the grinding cylinder 206 for grinding and polishing the surface of the quartz tube 102 to remove burrs. The worktable 1 is equipped with a rotary engagement mechanism for positioning and rotating the quartz tube 102.

[0020] The rotary meshing mechanism includes a long support plate 201 fixedly connected to the worktable 1. A motor 202 is fixedly connected to the long support plate 201. A long rotating rod 203 is fixedly connected to the output shaft of the motor 202, and the long rotating rod 203 and the long support plate 201 are rotatably connected. An I-shaped rotating cylinder 204 is fixedly connected to the end of the long rotating rod 203 away from the motor 202. The I-shaped rotating cylinder 204 includes a central rod coaxial with the long rotating rod 203 and discs fixedly connected to both ends of the central rod. The two discs of the I-shaped rotating cylinder 204 can fit tightly against the cylindrical outer wall of the rubber hard disk 105, so that when the I-shaped rotating cylinder 204 rotates, it can drive the rubber hard disk 105 to rotate. In this embodiment, the telescopic pole 104 supports two-stage stroke control, that is, the telescopic pole 104 can push the rubber hard disk 105 to contact the first disk or the second disk of the I-shaped rotating drum 204. When the rubber hard disk 105 contacts the two disks of the I-shaped rotating drum 204, it will rotate with the I-shaped rotating drum 204. Thus, the laser beam emitted by the laser cutter 106 can divide the quartz tube 102 into three segments.

[0021] A synchronous belt assembly 205 is connected to the long rotating rod 203. The synchronous belt assembly 205 consists of two pulleys distributed vertically and a synchronous belt sleeved on the two pulleys. The upper pulley is fixedly connected to the outer surface of the long rotating rod 203. Several teeth are arranged around the outer wall of the lower pulley and the outer wall of the grinding cylinder 206, and the teeth of the grinding cylinder 206 and the teeth on the lower pulley are meshed with each other. The side of the grinding cylinder 206 facing the quartz tube 102 and the side facing away from the quartz tube 102 are both grinding surfaces. A short rotating rod 2051 is fixedly connected to the center of the lower pulley, and the short rotating rod 2051 is rotatably connected to the long support plate 201. Two toothed plates 207 are provided on both sides of the grinding cylinder 206, with one toothed plate 207 positioned higher than the other. Elastic telescopic rods 208 are fixedly connected to the bottom ends of both toothed plates 207 and the worktable 1. Slotted plates 209 are slidably connected to both toothed plates 207, and T-shaped sliders 210 are fixedly connected to the slotted plates 209. T-shaped grooves are formed on the toothed plates 207 that slidably connect with the T-shaped sliders 210. A spring 211 is fixedly connected between the bottom end of the T-shaped slider 210 and the bottom end of the T-shaped groove. Arc plate frames 212 are fixedly connected to the plates of both slotted plates 209, with one arc plate frame 212 located above the quartz tube 102 and the other arc plate frame 212 located below the quartz tube 102. Each arc plate frame 212 has three pulleys 213 on its inner wall frame. Each pulley 213 consists of a U-shaped frame and a roller rotatably connected to each U-shaped frame. Each U-shaped frame is fixedly connected to the inner wall of the arc plate frame 212, and each roller can rotate on the corresponding connected U-shaped frame.

[0022] The above solution is adopted: such as Figure 1 and Figure 2As shown, when the quartz tube 102 moves to contact the grinding cylinder 206, the motor 202 installed on the long support plate 201 is started, which drives the long rotating rod 203 to rotate, thereby driving the synchronous belt assembly 205 and the I-shaped rotating cylinder 204 to rotate synchronously. At that time, the rubber hard disk 105 will also come into contact with the disc on the I-shaped rotating cylinder 204. Thus, when the I-shaped rotating cylinder 204 rotates, it drives the rubber hard disk 105 and the quartz tube 102 to rotate synchronously. The long rotating rod 203 in the rotating state will also drive the synchronous belt assembly 205 to rotate, thereby driving the grinding cylinder 206 to rotate. The rotating grinding cylinder 206 grinds and polishes the tube opening on the quartz tube 102 to remove burrs. Meanwhile, due to the meshing action of the teeth, the rotation of the grinding cylinder 206 causes the two toothed plates 207 to move closer to each other, that is, the toothed plate 207 in the upper position moves downward and the toothed plate 207 in the lower position moves upward, thereby causing the two grooved plates 209 and the arc plate frame 212 to move closer to each other. The pulley 213 installed on the arc plate frame 212 moves downward and fits against the outer wall of the quartz tube 102, clamping and limiting the quartz tube 102 (the pulley 213 can rotate, and its presence does not affect the rotation of the quartz tube 102), which can effectively prevent the tube from being thrown or deviated during cutting. During the upward or downward movement of the toothed plates 207, the elastic telescopic rod 208 is stretched upward or compressed downward.

[0023] When faced with quartz tubes 102 of different diameters, the arc plate frame 212 moves upward or downward under the pressure of the quartz tubes 102, thereby causing the groove plate 209 to move accordingly. This, in turn, causes the T-shaped slider 210 connected to the groove plate 209 to slide upward or downward within the T-shaped groove, compressing or stretching the spring 211. Under the elastic force of the spring 211, the arc plate frame 212 maintains a clamping force on the quartz tube 102. The sliding design of the groove plate 209 on the toothed plate 207 can accommodate quartz tubes of various diameters. After processing is completed, the elastic telescopic rod 208 and the spring 211 automatically reset under the elastic restoring force, thereby causing the toothed plate 207, the groove plate 209, and the arc plate frame 212 to automatically reset for the next processing.

[0024] The overall diameter of the pulley and the polishing cylinder 206 is smaller than that of the rubber hard disk 105 and the I-shaped rotating cylinder 204. The smaller the diameter, the faster and more rotations it will make. Therefore, when the quartz tube 102 rotates once, the polishing cylinder 206 can rotate multiple times, thus enabling thorough polishing of the opening of the quartz tube 102.

[0025] When the cut-off section of the tube is being cut, the operator can hold the cut-off section of the tube and align the unpolished end of the tube with the side of the polishing cylinder 206 away from the quartz tube 102 to remove burrs.

[0026] The workbench 1 is equipped with a snap-fit ​​positioning mechanism, which includes a hollow slide plate 214 and a T-shaped clamping plate 216 fixedly connected to the workbench 1. Multiple rectangular slots 215 are formed on both ends of the hollow slide plate 214, and the T-shaped clamping plate 216 can be inserted into the rectangular slots 215. A rectangular clamping plate 217 is slidably connected to the inner wall of the hollow slide plate 214. Long strip grooves are formed on both ends of the rectangular clamping plate 217 near the bottom, and the inner walls of the two long strip grooves can snap into the T-shaped clamping plate 216. The top end of the rectangular clamping plate 217 is fixedly connected to the bottom end of the laser cutter 106.

[0027] The above solution is adopted: such as Figure 7 and Figure 8 As shown, when cutting quartz tubes 102 of different diameters, the T-shaped clamping plate 216, which is locked in the rectangular clamping slot 215, can be easily pulled out manually. Then, the T-shaped clamping plate 216 will separate from the rectangular clamping plate 217, which is fixedly connected to the bottom of the laser cutter 106, and disengage from the two long slots on the rectangular clamping plate 217. This allows the laser cutter 106 and the rectangular clamping plate 217 to be moved down as a whole to the appropriate position of the rectangular clamping slot 215. Then, the T-shaped clamping plate 216 is inserted into the rectangular clamping slot 215, and the T-shaped clamping plate 216 slides into the long slot of the rectangular clamping plate 217, thereby limiting the rectangular clamping plate 217 and the laser cutter 106. In this embodiment, three sets of rectangular slots 215 formed on the hollow sliding plate 214 correspond to three different diameter quartz tubes 102 that can be clamped onto the rubber hard disk 105 from top to bottom. This allows the laser cutter 106 to be adjusted in height to ensure that the emitted laser beam is aligned with the body of the quartz tube 102. When the quartz tube 102 rotates, the laser beam penetrates its wall for laser cutting. This enables the cutting of quartz tubes 102 of various diameters.
