Technical Field

[0001] This application relates to the field of quartz tube manufacturing technology, and in particular to an automatic cutting machine for quartz tube manufacturing. Background Technology

[0002] Quartz tubes are a special industrial glass made of silicon dioxide, possessing a range of excellent physical and chemical properties. It is a highly effective basic material, widely used in devices such as electric heaters, electric ovens, and electric warmers for heating. The production of quartz tubes often involves cutting them using specialized cutting equipment. These devices are typically designed to accommodate the hardness and fragility of quartz tubes.

[0003] According to announcement number CN210765000U, an automatic cutting machine for quartz tube production is disclosed. This technology discloses "a machine frame, a conveying mechanism, a cutting mechanism, and a clamping mechanism; the conveying mechanism includes a conveying motor and a conveying shaft, with conveying wheels on the conveying shaft; the cutting mechanism includes a first mounting plate, a hydraulic cylinder, and a cutting motor, with the hydraulic cylinder fixed to the first mounting plate and a blade holder connected to the hydraulic cylinder, on which cutting blades are mounted; the clamping mechanism includes a second mounting plate, a clamping motor, and two clamping blocks, with a slide rail mounted on the second mounting plate, two sliders connected to the slide rail, connecting plates fixed to the two sliders respectively, the two clamping blocks connected to the two connecting plates respectively, and a lead screw connected to the clamping motor penetrating the two sliders; the two sliders are respectively provided with threaded holes for the lead screw to pass through and to engage with the lead screw thread, and the threads of the threaded holes on the two sliders have opposite directions, etc., which has the technical effect of effectively cutting quartz tubes with high efficiency."

[0004] Regarding the aforementioned technologies, the inventors believe that most quartz tube cutting devices cannot effectively position and fix the tube, resulting in deviation or deformation during the cutting process. Furthermore, they cannot perform multi-axis movement of the main cutting components, and their cutting heads cannot be height adjusted according to cutting requirements. Summary of the Invention

[0005] The purpose of this application is to provide an automatic cutting machine for quartz tube production, so as to improve the problems of not being able to position and fix the quartz tube and not being able to move the cutting head in multiple axes.

[0006] The technical solution provided in this application for an automatic cutting machine for quartz tube production is as follows:

[0007] An automatic cutting machine for quartz tube production includes an operating table. First slide rails are fixedly connected to both ends of the operating table. A gantry frame is slidably connected to the outer surfaces of the two first slide rails. A second electric slide rail is fixedly installed at one end of the gantry frame. An adjustment device is slidably connected to the outer surface of the second electric slide rail. Two clamping devices are fixedly installed on one side of the top of the operating table. Each clamping device includes a base plate. Two fixing pins are fixedly connected to the bottom end of the base plate. A cylinder is rotatably connected to one side of the top of the base plate. A rotating component is fixedly connected to the output end of the cylinder. A support rod is rotatably connected to the outer surface of the rotating component. A clamping plate is fixedly installed at one end of the support rod. Support plates are rotatably connected to both ends of the support rod. Clamping plates are fixedly connected to the top and bottom ends of both support plates. A second fixing groove is provided at one end of each clamping plate. The bottom end of the support plate is fixedly connected to the top end of the base plate.

[0008] By adopting the above technical solution, the operator can place the quartz tube between two clamping devices, and rotate the support rod along one end of the support plate under the output of the cylinder. Through the lever principle, the clamping plate at one end of the support rod is pressed downward, thereby achieving the fixed clamping of the quartz tube.

[0009] Optionally, the adjustment device includes a bracket, one end of which is fixedly mounted with an electric slider, one end of which is slidably sleeved with the outer surface of the second electric slide rail. Guide rods are fixedly connected to the inner walls of the upper and lower ends of the bracket. A lead screw is rotatably connected to the upper and lower inner walls of the bracket. A transmission plate is threaded onto the outer surface of the lead screw. Both guide rods pass through the transmission plate. A connecting plate is fixedly mounted to one end of the transmission plate. A laser cutting head is fixedly connected to one end of the connecting plate. A motor is fixedly mounted to the top of the bracket. The output end of the motor passes through the bracket and is fixedly connected to one end of the lead screw.

[0010] By adopting the above technical solution, the second electric slide rail at one end of the gantry frame works in conjunction with the electric slider in the adjustment device to drive the support to move along the x-axis. The motor in the adjustment device is started to rotate the lead screw, thereby moving the transmission plate up and down under the stability of the two guide rods, so as to realize the z-axis movement of the laser cutting head.

[0011] Optionally, the top of the operating table is provided with a plurality of first fixing slots, which are arranged in a rectangular array, and the diameter of each of the plurality of first fixing slots is the same as the diameter of the fixing pin.

[0012] By adopting the above technical solution, multiple rectangular array of first fixing slots provide a fixing method in which the connection angle of the two fixing pins in the clamping device can be arbitrarily changed, so that the clamping device can be connected to any two first fixing slots through the two fixing pins at the bottom, thereby achieving the purpose of convenient installation and fixing.

[0013] Optionally, a backplate is fixedly installed on one side of the top of the operating table, and two fans are fixedly installed on one end of the backplate.

[0014] By adopting the above technical solution, the back plate located on the back of the two clamping devices and the two fans can be used to cool the cut quartz tube and to blow away the residue on the worktable after cutting.

[0015] Optionally, the support rod is L-shaped.

[0016] By adopting the above technical solution, the "L"-shaped support rod rotates at one end and performs lever movement under the support of the support plate, thereby achieving the purpose of applying downward pressure to the clamping plate.

[0017] Optionally, the two clamping plates are mirror-distributed, and the two second fixing slots are arc-shaped.

[0018] By adopting the above technical solution, two mirror-distributed clamping plates fit together the two end faces of the quartz tube through two identical second fixing grooves, which facilitates pressing and fixing by applying downward pressure through the upper clamping plate.

[0019] Optionally, the two guide rods are mirror-distributed, and the outer surfaces of both guide rods are slidably sleeved with the inner wall of the transmission plate.

[0020] By adopting the above technical solution, the two guide rods are used to prevent the transmission plate from shifting during movement, ensuring the stability of the transmission plate's up and down movement, and providing vertical guidance for the movement of the transmission plate.

[0021] Optionally, the bracket is U-shaped.

[0022] The purpose of adopting the above technical solution is to provide a certain distance of lifting space for the movement of the transmission plate and the rotation of the lead screw, so as to realize the z-axis movement of the laser cutting head.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By setting a fixing device, this utility model can accurately determine the relative position between the quartz tube and the laser cutting head, ensuring the positional accuracy of the quartz tube, preventing the quartz tube from shaking and deforming during processing, and improving the stability of processing accuracy.

[0025] 2. This utility model, by setting an adjustment device, facilitates the controllable adjustment of the cutting height of quartz tube surfaces with different cutting requirements, and adjusts the relative position of the laser focus and the quartz tube, making the cutting more precise and flexible.

[0030] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail below.

[0031] Example: An automatic cutting machine for quartz tube production, referring to... Figure 1 The system includes an operating table 1, with first slide rails 12 fixedly connected to both ends of the operating table 1. A gantry frame 2 is slidably sleeved on the outer surface of the first slide rails 12. A second electric slide rail 21 is fixedly welded to one end of the gantry frame 2. An adjustment device 3 is slidably provided on the outer surface of the second electric slide rail 21. Multiple first fixing slots 11 are provided on the outer surface of the operating table 1 in a rectangular array. The multiple first fixing slots 11 are used in conjunction with the bottom end of the clamping device 4. A back plate 13 is fixedly connected to one side of the top of the operating table 1. Two fans 14 are fixedly connected to one end of the back plate 13 by bolts. The two mirror-shaped fans 14 face the two clamping devices 4. The two fans 14 can blow on the outer surface of the operating table 1 and the two clamping devices 4 to quickly cool the quartz tube and clean the table surface.

[0032] Reference Figure 2The clamping device 4 includes a base plate 41 and a cylinder 42. One end of the base plate 41 protrudes upward and extends and is fixedly welded to one side of the bottom end of the support plate 46. The outer surface of one end of the base plate 41 is rotatably connected to one end of the cylinder 42. The output end of the cylinder 42 is fixedly connected to a rotating part 43 by bolts. The bottom end of the rotating part 43 abuts against and slides against the top end of the base plate 41. The inner walls of both ends of the rotating part 43 are rotatably connected to a rotating shaft. The outer surface of the rotating shaft is sleeved with the bottom end of the support rod 45. The rotating part 43 can be moved by the output of the cylinder 42, thereby driving the support rod 45 to rotate.

[0033] Reference Figure 2 Two fixing pins 40 are fixedly welded to the bottom end of the base plate 41. The distance between the two fixing pins 40 and the diameter of each fixing pin 40 correspond to multiple first fixing grooves 11. The cylinder 42, which is rotatably connected to one end of the base plate 41, provides the feasibility for moving the rotating part 43. The top side of the base plate 41 is fixedly welded to the bottom side of the support plate 46. One end of the support plate 46 is rotatably connected to the outer surface of the support rod 45 through a shaft, providing a fixed rotational support for the rotation of the support rod 45. Clamping plates 47 are fixedly welded to the bottom side of the support rod 45 and the top side of the support plate 46. The outer surfaces of the two clamping plates 47 are provided with second fixing grooves 48 of the same diameter. The two arc-shaped second fixing grooves 48 provide the feasibility for fitting the outer surface of the quartz tube. The L-shaped support rod 45, through the movement of the rotating part 43, exerts a lever effect at one end of the support plate 46 to press one of the clamping plates 47 downward and clamp the quartz tube.

[0034] Reference Figure 3 The adjusting device 3 includes a bracket 31 and an electric slider 30. One end of the electric slider 30 is slidably sleeved with the outer surface of the second electric slide rail 21, and the other end of the electric slider 30 is fixedly connected to one end of the bracket 31 by bolts. The bracket 31 can be moved along the x-axis by the cooperation of the electric slider 30 and the second electric slide rail 21. Two guide rods 32 are fixedly connected to the inner walls of the upper and lower ends of the bracket 31 and are rotatably connected to a lead screw 33. A motor 37 is fixed at the top of the lead screw 33, which can drive the lead screw 33 to rotate between the inner walls of the two sides of the bracket 31 under the output of the motor 37.

[0035] Reference Figure 3The outer surface of the lead screw 33 is threaded with a transmission plate 34. The outer surfaces of the two guide rods 32 are slidably sleeved with the inner walls of both sides of the transmission plate 34, providing a stable guide for the transmission plate 34 to move up and down. As the lead screw 33 rotates, it can drive the transmission plate 34 to move up and down under the stability of the two guide rods 32. One end of the transmission plate 34 is fixedly connected to a connecting plate 35 by bolts. One end of the connecting plate 35 is fixedly welded with a laser cutting head 36. Under the output of the motor 37, the transmission plate 34 and the connecting plate 35 can be driven to move up and down, thereby driving the laser cutting head 36 to move along the z-axis.

[0036] The implementation principle of this application embodiment is as follows: When it is necessary to clamp the quartz tube, the quartz tube is placed in the second fixing groove 48 at one end of the clamping plate 47 of one of the two clamping devices 4. Then, the cylinder 42 is activated, and the output end of the cylinder 42 pushes out the rotating part 43. The pushed-out rotating part 43 drives the support rod 45 to rotate stably along one end of the support plate 46. The clamping plate 47 at one end of the support rod 45 cooperates with the clamping plate 47 at the bottom end through the second fixing groove 48 to lock and fix the two end faces of the quartz tube, thereby clamping and fixing the quartz tube. The operator can insert the clamping device 4 into any two first fixing grooves 11 through the two fixing pins 40 at the bottom end of the base plate 41 to facilitate fixing the quartz tube at different angles.

[0037] When the quartz tube needs to be cut, the gantry 2 is started to move along the y-axis on the outer surface of the first slide rail 12. The second electric slide rail 21 at one end of the gantry 2 works with the electric slider 30 in the adjustment device 3 to move along the x-axis. Then the motor 37 in the adjustment device 3 is started. The output end of the motor 37 drives the lead screw 33 to rotate. The rotating lead screw 33 drives the transmission plate 34 to move vertically and stably up and down under the stabilization of the two guide rods 32. This causes the laser cutting head 36, which is fixedly connected to one end of the transmission plate 34 through the connecting plate 35, to move up and down along the z-axis. This facilitates the height adjustment of the laser cutting head 36, thereby achieving the purpose of three-axis movement of the laser cutting head 36. After the cutting is completed, the quartz tube or the table surface of the operating table 1 can be purged and cooled by the two fans 14 in the back plate 13 on one side of the operating table 1.

Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
