Description

Technical Field

[0001] The utility model relates to the technical field of quartz tube production and processing, in particular to an automatic cutting device for large-size quartz tubes. Background Art

[0002] Large-sized quartz tubes have high temperature resistance, corrosion resistance, good thermal stability, excellent light transmittance and excellent electrical insulation properties. Thanks to their unique physical and chemical properties, large-sized quartz tubes have a wide range of applications, such as optoelectronics, aerospace technology, biomedicine and semiconductor processing industries.

[0003] Since quartz tubes have a wide range of applications, different application scenarios have different requirements for the size and shape of quartz tubes. Through cutting, quartz tubes of different lengths, diameters and wall thicknesses can be obtained according to specific needs. When the quartz tube is cut mechanically, the high-speed rotating cutter contacts the surface of the quartz tube at a certain speed and pressure, and cuts it through friction and cutting force.

[0004] During cutting, the cutter is always in a state of high-speed rotation and in friction with the quartz tube, resulting in the heat generated by the friction on the cutter cannot be dissipated in time. The accumulated heat will cause the material of the cutter to soften and the hardness to decrease, affecting the cutting efficiency and time. High temperature may also cause changes in the stress distribution inside the cutter, causing it to deform or crack, further shortening its service life. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model is further described below in conjunction with embodiments.

[0024] Example: Refer to Figures 1 to 5, an automatic cutting device for a large-size quartz tube comprises an "L"-shaped fixed frame 1, a slider 4 is slidably mounted on the fixed frame 1, a connecting plate 3 is fixedly mounted on the slider 4, a motor 2 is fixedly mounted on the connecting plate 3, the output end of the motor 2 passes through the connecting plate 3 and the slider 4 and is fixedly connected to the main rotating shaft 5, a slave rotating shaft 7 is rotatably mounted on the side of the fixed frame 1, a pulley 8 is fixedly mounted on the main rotating shaft 5 and the slave rotating shaft 7, a belt 9 is mounted on the pulley 8, the main rotating shaft 5 and the slave rotating shaft 7 are connected through the pulley 8 and the belt 9, a cutting blade 6 is fixedly mounted on the main rotating shaft 5, a tensioning mechanism is arranged between the main rotating shaft 5 and the slave rotating shaft 7, a missing gear 10 is fixedly mounted on the slave rotating shaft 7, a plurality of main supporting frames 11 are fixedly mounted on the fixed frame 1, a rotating gear 12 is arranged above the fixed frame 1, the missing gear 10 is meshed or separated with the rotating gear 12, and a fixing mechanism is arranged on the rotating gear 12; when cutting the quartz tube, the quartz tube is first placed by a machine On the main support frame 11, the fixing mechanism on the rotating gear 12 is placed into the quartz tube, and the rotating gear 12 is meshed with the missing gear 10, and the motor 2 and the tensioning mechanism are started. The output end of the motor 2 drives the main shaft 5 and the cutting blade 6 to rotate. At the same time, the main shaft 5 drives the slave shaft 7 to rotate through the pulley 8 and the belt 9. When the slave shaft 7 rotates, it drives the missing gear 10 and the rotating gear 12 meshed with the missing gear 10 to rotate. When the rotating gear 12 rotates, it drives the quartz tube to rotate through the fixing mechanism. The missing gear 10 makes the quartz tube rotate on the main support frame 11 in a "rotation-stagnation-rotation" cycle, so that the cutting blade 6 has time to dissipate heat when rotating, reducing the damage of the high temperature to the cutting blade 6, thereby avoiding the cutting efficiency from being affected. The tensioning mechanism enables the connecting plate 3 and the slider 4 to drive the motor 2 and the cutting blade 6 to move toward the quartz tube, thereby completely cutting the quartz tube and keeping the belt 9 taut.

[0025] Specifically, the fixing mechanism includes a support shaft 13 fixedly connected to the rotating gear 12, an inflatable rubber ring 14 is fixedly installed on the support shaft 13, and an inflatable tube (not shown in the figure) is fixedly installed on the inflatable rubber ring 14, and the inflatable tube runs through the support shaft 13 to one end of the support shaft 13; after the rotating gear 12 is adjusted to a suitable position and meshed with the missing gear 10, air is injected into the inflatable rubber ring 14 from the inflatable tube, and the air causes the inflatable rubber ring 14 to gradually expand until the inflatable rubber ring 14 fits against the inner wall of the quartz tube, and the friction between the inflatable rubber ring 14 and the inner wall of the quartz tube enables the rotating gear 12 to drive the quartz tube to rotate through the support shaft 13 and the inflatable rubber ring 14.

[0026] Furthermore, a fixing ring 15 is fixedly installed on one end of the support shaft 13 close to the missing gear 10, the inflation tube passes through the fixing ring 15 and is fixedly connected to a needle valve 16, and a sealing cover 17 is threadedly connected to the needle valve 16; air is injected into the inflation rubber ring 14 through the needle valve 16, and the fixing ring 15 supports the inflation tube. After the inflation rubber ring 14 is expanded, the inflation tool is quickly separated from the needle valve 14, and the needle valve 14 is quickly closed so that the gas in the inflation rubber ring 17 will not overflow as much as possible, and the sealing cover 17 is tightened on the needle valve 16 to prevent dust generated during cutting from falling on the needle valve 14.

[0027] Specifically, the tensioning mechanism includes a main slide groove 18 opened on the fixed frame 1, the slider 4 is slidably connected to the main slide groove 18, an electric push rod 19 is fixedly installed on the inner wall of the main slide groove 18, the output end of the electric push rod 19 is fixedly connected to the slider 4, and a slave slide groove 20 is opened on the fixed frame 1, and a stretching mechanism is arranged in the slave slide groove 20; when cutting, the electric push rod 19 is started, and the speed of the electric push rod 19 is controlled so that the output end of the electric push rod 19 slowly pulls the slider 4 and the connecting plate 3 toward the quartz tube, thereby moving the motor 2, the main shaft 5 and the cutting blade 6 toward the quartz tube. During this process, the stretching mechanism keeps the belt 9 in a taut state to prevent it from affecting the normal operation and rotation of the main shaft 5 and the slave shaft 7.

[0028] Furthermore, the stretching mechanism includes a tensioning shaft 21 slidably installed in the slave slide 20, and a tensioning wheel 24 is rotatably installed on the tensioning shaft 21. The tensioning wheel 24 is sleeved in the belt 9, and a tensioning spring 22 is fixedly installed on the bottom wall inside the slave slide 20, and the other end of the tensioning spring 22 is fixedly connected to the tensioning shaft 21; when not cut, the tensioning shaft 21 is located at the bottom of the slave slide 20, and the tensioning spring 22 is compressed at this time. As the connecting plate 3 and the slider 4 move, when the belt 9 becomes loose, the rebound force of the tensioning spring 22 pushes the tensioning shaft 21 upward, so that the belt 9 remains in a taut state, preventing the belt 9 from falling off the pulley 8 and the tensioning wheel 24.

[0029] Furthermore, a slave support frame 23 is fixedly installed on the fixed frame 1, and the top of the slave support frame 23 is arc-shaped, and the top of the slave support frame 23 is in contact with the slave shaft 7; the slave support frame 23 supports the slave shaft 7 to prevent the slave shaft 7 from deviating downward due to the gravity of the missing gear 10.

[0030] The working principle of the device is as follows: when cutting a quartz tube, firstly, the quartz tube is mechanically placed on the main support frame 11, the support shaft 13 and the inflatable rubber ring 14 on the rotating gear 12 are placed in the quartz tube, and the rotating gear 12 is meshed with the missing gear 10, and air is injected into the inflatable rubber ring 14 through the needle valve 16. After the inflatable rubber ring 14 expands, the sealing cover 17 is tightened on the needle valve 16 to prevent the air in the inflatable rubber ring 14 from overflowing, and the motor 2 and the electric push rod 19 are started. The output end of the motor 2 drives the main shaft 5 and the cutting blade 6 to rotate, and at the same time, the main shaft 5 drives the slave shaft 7 to rotate through the pulley 8 and the belt 9. When the slave shaft 7 rotates, it drives the missing gear 10 and the rotating gear 12 meshed with the missing gear 10 to rotate. When the rotating gear 12 rotates, the inflatable rubber ring 14 is rotated. The friction between the gas ring 14 and the quartz tube drives the quartz tube to rotate. The missing gear 10 makes the quartz tube rotate on the main support frame 11 in a cycle of "rotation-stagnation-rotation", so that the cutting blade 6 has time to dissipate heat during rotation, reducing the damage to the cutting blade 6 caused by high temperature, thereby avoiding affecting the cutting efficiency. When the cutting blade 6 cuts the quartz tube, the electric push rod 19 moves the connecting plate 3, the motor 2 and the cutting blade 6 toward the quartz tube, thereby completely cutting the quartz tube. With the movement of the connecting plate 3 and the slider 4, when the belt 9 becomes loose, the rebound force of the tensioning spring 22 pushes the tensioning shaft 21 upward, thereby keeping the belt 9 in a taut state to prevent the belt 9 from falling off the pulley 8 and the tensioning wheel 24.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents.
