Description
Technical Field
[0001] This utility model relates to the field of glass tube cutting technology, specifically a glass tube non-powered rotating cutting device. Background Technology
[0002] During the manufacturing process of a glass flow meter, it is necessary to cut the glass tube to a specific size.
[0003] In existing technologies, glass tubes are typically cut using a grinding wheel. During the cutting process, the glass tube is first fixed in place, and then the cutting point of the glass tube is aligned with the cutting edge of the high-speed rotating grinding wheel. The glass tube is then moved so that the grinding wheel cuts along the fixed cutting point. When the cutting edge of the grinding wheel comes into contact with the cutting point of the glass tube, the stress from the rotating cutting of the grinding wheel is concentrated at the cutting point because the glass tube is fixed. As the glass tube continues to move, the cutting edge of the grinding wheel continues to cut into the glass tube wall. Because the stress is concentrated at the point, the glass tube may become unstable during continuous cutting, which may cause cracks, breakage, or explosion of the glass tube. This not only affects the quality and efficiency of the glass tube cutting operation but also results in the waste of glass tubes. Utility Model Content

[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] This utility model patent uses a gripper mechanism to grasp a glass tube, and then uses a movement control mechanism to control the position of the gripper mechanism on the base plate. This allows the glass tube grasped by the gripper mechanism to come into contact with the activated cutting mechanism.

[0035] Example 1:
[0036] Please refer to Figures 1-7 This utility model provides a glass tube non-powered rotating cutting device, including a base plate frame 1, a moving control mechanism 2 set on the base plate frame 1, a gripper mechanism 3 installed on the top of the moving control mechanism 2 for gripping the glass tube 5, and a cutting mechanism 4 for cutting the glass tube 5.
[0037] In this embodiment, the worker places the glass tube to be cut on the gripper mechanism 3, controls the gripper mechanism 3 to stably grip the glass tube 5, starts the cutting mechanism 4, and controls the movement of the gripper mechanism 3 through the movement control mechanism 2 so that the glass tube to be cut moves to abut against the cutting mechanism 4. At this time, the cutting mechanism 4 begins to cut the glass tube. The worker holds the end of the glass tube 5 to be cut and continuously drives the gripper mechanism 3 to move so that the cutting mechanism 4 can continuously cut the glass tube. When the part of the glass tube 5 to be cut is completely cut off, the cutting mechanism 4 stops to complete the cutting of the glass tube 5. After the gripper mechanism 3 is driven back to its original position through the movement control mechanism 2, the gripper mechanism 3 is released and the glass tube segment is taken out.
[0038] like Figure 1 As shown, the cutting mechanism 4 includes: a cutting base 41, a mounting column 42 mounted on the cutting base 41, a second motor 43 mounted on the mounting column 42, and a grinding wheel 44 coaxially mounted with the output shaft of the second motor 43; the outermost edge of the grinding wheel 44 is close to the outer wall surface of the glass tube 5.
[0039] In this embodiment, the second motor 43 drives the grinding wheel 44 to rotate and cut the glass tube 5 held by the gripper mechanism 3. The blade on the outside of the grinding wheel 44 abuts against the position of the glass tube 5 to be cut, and the glass tube 5 is continuously moved by the movement control mechanism 2 so that the blade continuously cuts the glass tube 5, thereby cutting the glass tube 5.
[0040] To further explain, the rotation of the grinding wheel causes the blade to cut the glass tube 5 into a first glass tube segment and a second glass tube segment. After the cutting operation, the part gripped by the gripper mechanism 3 is the first glass tube segment, while the part held by the worker is the second glass tube segment.
[0041] like Figure 2 , Figure 3 and Figure 5 As shown, the gripper mechanism 3 includes: a support column 31, a first motor 32, and a gripper assembly 33; the support column 31 is installed on the top of the motion control mechanism 2, the first motor 32 is installed on one side of the support column 31 to drive the gripper assembly 33 to clamp or release, and the gripper assembly 33 is installed on the other side of the support column 31 to grip the glass tube 5.
[0042] Furthermore, the gripper assembly 33 includes two grippers 331 and a roller module 332 disposed on the gripping surface of the grippers 331 for assisting the rotation of the glass tube 5.
[0043] Furthermore, in this embodiment, there are two claws 331, which are respectively installed on the support column 31. The first motor 32 synchronously drives the two claws 331 to move synchronously to clamp or release the glass tube 5.
[0044] In this embodiment, the gripper mechanism 3 grips the glass tube 5, and then the position of the gripper mechanism 3 on the base plate frame 1 is controlled by the movement control mechanism 2. The glass tube 5 gripped by the gripper mechanism 3 can then come into contact with the activated cutting mechanism 4. The roller module 332 causes the glass tube 5 to rotate in the opposite direction under the rotation of the cutting mechanism 4, so that the stress of the cutting mechanism 4 cutting the wall of the glass tube 5 is evenly distributed and not concentrated at the cutting point, ensuring that the glass tube 5 will not crack or burst during cutting, thus ensuring the stability of the glass tube 5 during cutting. The roller module 332 enhances the overall efficiency of the cutting operation and further enhances the overall practicality of the device.
[0045] In this embodiment, the first motor 32 drives the two jaws 331 to move inward synchronously to clamp the glass tube 5. The movement control mechanism 2 controls the movement of the gripper mechanism 3, so that the glass tube 5 gripped by the jaws 331 moves to contact the blade of the grinding wheel 44. The grinding wheel 44 rotates under the drive of the second motor 43 and transmits a force in the opposite direction to the glass tube 5 it contacts. Under the action of the roller module 332, the glass tube 5 rotates in the opposite direction to the grinding wheel 44. When the blade of the grinding wheel 44 contacts the wall of the glass tube 5, the relative rotation of the glass tube 5 will evenly disperse the stress concentrated at the cutting point. This not only alleviates the heat effect generated during high-speed cutting, but also makes the force at the cutting point softer, ensuring the overall stability of the glass tube 5 when the wall is cut. This ensures that the glass tube 5 will not crack or shatter due to uneven force.
[0046] like Figure 5 As shown, the roller module 332 includes: a mounting base 3321 installed inside the claw 331, a mounting groove provided on the mounting base 3321, and two rolling bearings 3322 and claws 331 installed in the mounting groove.
[0047] In this embodiment, four rolling bearings 3322 on the two jaws 331 form a placement cavity. When the first motor 32 is started, the operator holds the glass tube 5 and places it into the placement cavity. As the two jaws 331 move inward synchronously, the placement cavity gradually shrinks until the glass tube is securely clamped. The operator then releases the glass tube 5, thus completing the placement of the glass tube. The movement control mechanism 2 moves the glass tube 5 to contact the cutting edge of the grinding wheel 44. The rolling bearings 3322 allow the glass tube 5, which is subjected to the rotational force of the grinding wheel 44, to rotate in the opposite direction, evenly distributing the stress at the cutting point. This ensures the stability of the glass tube 5 during cutting, prevents the glass tube 5 from breaking or bursting, and enhances the stability and efficiency of the cutting operation.
[0048] like Figure 6 As shown, the rolling bearing 3322 includes: a fixed shaft 33221 mounted on the mounting base 3321, and an inner ring wheel 33222 and an outer ring wheel 33224 arranged sequentially from the inside to the outside on the fixed shaft 33221. A plurality of bearing balls 33223 are arranged between the inner ring wheel 33222 and the outer ring wheel 33224. The inner ring wheel 33222 is fixedly mounted on the fixed shaft 33221, and the rotation of the outer ring wheel 33224 drives the glass tube 5 to rotate.
[0049] In this embodiment, when the glass tube 5 is subjected to force, the rolling bearing 3322 enables the glass tube 5 to rotate in the direction of the force. The inner ring wheel 33222 is fixedly installed with the fixed shaft 33221, and the friction is reduced by the arrangement of several bearing balls 33223, so that the outer ring wheel 33224 can rotate 360 degrees flexibly relative to the inner ring wheel 33222, which enhances the flexibility of the glass tube 5 rotation and ensures the stability of the glass tube 5 during cutting.
[0050] like Figures 1-4 As shown, the motion control mechanism 2 includes: a slide rail mounted on the base plate 1, at least two movable seats 21 slidably mounted on the slide rail, and at least two mounting seats 22 mounted on the base plate 1; an x-axis guide rail 23 parallel to the slide rail is provided between the mounting seats 22 along the x-axis direction, and a y-axis guide rail 24 perpendicular to the slide rail is provided between the mounting seats 22 and the movable seats 21 along the y-axis direction; and a gripper mechanism 3 is mounted on the mounting seats 22.
[0051] To further explain, the mounting base 22 includes an upper part 221 and a lower part 222, both of which are provided with mounting holes 223 for the x-axis guide rail 23 or the y-axis guide rail 24 to pass through.
[0052] In this embodiment, the operator pushes the mounting base 22 to move on the x-axis guide rail 23. Due to the setting of the y-axis guide rail 24, the fixed base 21 slides on the slide rail accordingly, which can adjust the distance between the mounting bases 22, and thus the distance between the gripper mechanisms 3, so as to adaptively grip glass tubes 5 of different lengths and enhance the overall practicality of the device. The operator assists the mounting base 22 to move on the y-axis guide rail 24, which can adjust the position of the gripper mechanism 3 that has gripped the glass tube 5 on the base plate frame 1, so that it is close to the cutting edge of the grinding wheel 44 of the cutting mechanism 4. After starting the cutting mechanism 4, the operator holds the end of the glass tube 5 that needs to be cut and pushes the mounting base 22 to move at a constant speed on the y-axis guide rail 24, so that the blade of the grinding wheel 44 cuts the wall of the glass tube 5 at a constant speed. The mounting base 22 continues to move until the grinding wheel 44 completely cuts off the glass tube 5. At this time, the cutting operation of the glass tube 5 is completed. The operator closes the cutting mechanism 4, returns the mounting base 22 to its original position, and then controls the gripper mechanism 3 to release, remove the first glass tube segment, and collect it together with the second glass tube segment in hand.
[0053] Furthermore, both the upper part 221 and the lower part 222 of the mounting base 22 are provided with mounting holes 223. The mounting holes 223 enhance the installation flexibility of the x-axis guide rail 23 and the y-axis guide rail 24. While ensuring that the x-axis guide rail 23 and the y-axis guide rail 24 are parallel to the base plate frame 1, the x-axis guide rail 23 and the y-axis guide rail 24 can be flexibly installed in the mounting holes 223 of the upper part 221 or the mounting holes 223 of the lower part 222.
[0054] Example 2:
[0055] Example 2 differs from Example 1 in that: Figure 8 As shown, there are 3 jaws 331-1. The three jaws 331-1 are installed on the support column 31 via the mounting plate 333. The first motor 32 drives the three jaws 33 to move synchronously to clamp or release the glass tube 5.
[0056] In this embodiment, when the glass tube 5 is placed, the first motor 32 drives the three jaws 331-1 to move inward synchronously to clamp the glass tube 5; after the cutting operation is completed, the first motor 32 drives the three jaws 331-1 to move outward synchronously to remove the cut glass tube 5. The cooperation of the three jaws 331-1 can stably clamp the glass tube 5, and the number of rolling bearings 3322 on the three jaws 331-1 can be adaptively set. The cooperation of multiple rolling bearings 3322 can make the glass tube 5 rotate more flexibly, improve the flexibility of the glass tube 5 rotation, thereby improving the stability of the glass tube 5 during cutting and improving the overall operating efficiency of the device.
[0057] It should be understood that the specific embodiments described above are only for explaining the present invention and are not intended to limit the present invention. Obvious variations or modifications derived from the spirit of the present invention are still within the protection scope of the present invention.
