Description

Technical Field

[0001] This utility model relates to the field of pipe manufacturing technology, and in particular to a clamping device for composite pipe manufacturing. Background Technology

[0002] A vacuum tube containing two or more electrode systems, each independently controlled by an electron flow, is called a composite tube. A composite tube is a tube created by combining two or more transistors in a specific configuration to function as a single transistor; it is also known as a Darlington transistor.

[0003] Traditional composite pipe cutting tools mostly use motor-driven saw blades for cutting, resulting in low dimensional accuracy and requiring a high level of worker skill. During the cutting process, the composite pipe positioning is unstable, easily producing beveled edges, which is detrimental to the later use of the composite pipe. Furthermore, when producing a variety of composite pipe types with varying specifications and dimensions, different lengths need to be cut. For example, the utility model patent disclosed in CN210818545U (hereinafter referred to as prior art D1) discloses a clamping device for composite pipe production, which has certain shortcomings in use. This device uses a cylinder to drive a piston rod to extend, thereby moving a limiting block to fix and limit the composite pipe. However, since the height of the cylinder and the limiting block is constant, it is inconvenient to effectively clamp pipes of different diameters. Therefore, we designed a clamping device for composite pipe production to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a clamping device for composite pipe production to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A clamping device for composite pipe production includes a workbench. The bottom of the workbench has a waste bin and a support column. The top of the workbench has a material collection groove communicating with the interior of the waste bin. A first threaded rod and a first guide rod are arranged parallel to each other within the material collection groove. A first motor is mounted on the outer surface of the workbench. The output shaft of the first motor is connected to one end of the first threaded rod. Two movable seats are threaded onto the outer side of the first threaded rod. The movable seats are slidably mounted on the outside of the first guide rod. A base plate is provided on the top of the movable seats. A fixed side plate is fixedly mounted on one side of the top of the base plate, and a movable side plate is slidably mounted on the other side. The fixed side plate... The surface has a first opening. A second threaded rod and a second guide rod are arranged parallel to each other between the upper and lower inner walls of the first opening. A lifting block is threaded onto the outer side of the second threaded rod and slidably fitted onto the outside of the second guide rod. A pressure plate is provided on the side of the lifting block near the movable side plate. A second opening corresponding to the first opening is provided on the surface of the movable side plate. A second motor is provided on the top of the fixed side plate, and the output shaft of the second motor is connected to one end of the second threaded rod. A support plate is provided at the bottom of the side of the movable side plate near the fixed side plate. A through groove is provided on the surface of the fixed side plate for the support plate to slide through. A composite pipe is placed on top of the support plate.

[0007] As a preferred embodiment of this utility model: the bottom of the movable side plate is provided with a slider, the top of the base plate is provided with a groove for the slider to slide into, a third threaded rod is rotatably provided in the groove, the slider is threadedly sleeved on the outside of the third threaded rod, a third motor is provided on the outer surface of the base plate, and the output shaft of the third motor is connected to one end of the third threaded rod.

[0008] As a further preferred embodiment of this utility model, the width of the material collection groove opening is greater than the length of the movable seat.

[0009] As a further preferred embodiment of this utility model: the fixed side plate, the movable side plate, the support plate and the pressure plate are all provided with a rubber layer on the side surface near the composite pipe.

[0010] As a further preferred embodiment of this utility model: the length direction of the third threaded rod is perpendicular to the length direction of the first guide rod.

[0011] As a further preferred embodiment of this utility model: two sets of external threads with opposite directions are symmetrically provided on both sides of the midpoint of the first threaded rod along its length direction.

[0012] As a further preferred embodiment of this utility model: the first threaded rod is rotatably disposed between the inner walls of the left and right sides of the material collection groove, and the first guide rod is fixedly disposed between the inner walls of the left and right sides of the material collection groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this device, the composite tube is placed on the support plate, and then the third motor is started. The third motor drives the third threaded rod to rotate, which in turn drives the slider to move. This causes the movable side plate to move towards the fixed side plate. During this process, the support plate can pass through the through slot, and the pressure plate also passes through the second through-hole until the composite tube is clamped between the fixed side plate and the movable side plate. Then, the second motor is started, and the second motor drives the second threaded rod to rotate. With the help of the second guide rod, the lifting block can be moved downward, which in turn drives the pressure plate to move downward until the pressure plate abuts against the upper part of the outer surface of the composite tube, so that the composite tube is clamped between the pressure plate and the support plate. The stability of the composite tube clamping and fixing is improved by setting rubber layers at multiple positions. Moreover, this device not only meets the processing requirements of composite tubes of different lengths, but is also suitable for pipes of different diameters. It is simple and convenient to operate, which greatly improves the applicability and practicality of the device and is worth promoting. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in the present utility model based on the specific circumstances.

[0021] Please see Figure 1-4 In this embodiment of the utility model, a clamping device for composite pipe production includes a workbench 1. The bottom of the workbench 1 is provided with a waste bin and a support column. The waste bin and support column are existing technologies and are not innovative aspects of this application; therefore, they are not described in detail and are not shown in the figures. For details, please refer to prior art document D1 (authorization announcement number CN210818545U). The top of the workbench 1 is provided with a material collection groove 2, which communicates with the interior of the waste bin. The material collection groove 2 is provided with a first threaded rod 7 and a first guide rod 3 arranged parallel to each other. The first threaded rod 7 has two sets of external threads in opposite directions symmetrically arranged on both sides of its midpoint along its length direction. The first threaded rod 7 is rotatably disposed between the left and right inner walls of the material collection groove 2. The first guide rod 3 is fixedly disposed between the left and right inner walls of the material collection groove 2. A first motor 6 is provided on the outer surface of the workbench 1. The output shaft of the first motor 6 is connected to one end of the first threaded rod 7. Two movable seats 4 are fitted onto the external threads of the first threaded rod 7. The movable seat 4 is slidably sleeved on the outside of the first guide rod 3. The top of the movable seat 4 is provided with a base plate 5. A fixed side plate 8 is fixedly provided on one side of the top of the base plate 5, and a movable side plate 9 is slidably provided on the other side. A first through-hole 13 is opened on the surface of the fixed side plate 8. A second threaded rod 11 and a second guide rod 12 are arranged parallel to each other between the upper and lower inner walls of the first through-hole 13. A lifting block 17 is threaded on the outside of the second threaded rod 11. The lifting block 17 is slidably sleeved on the outside of the second guide rod 12. A pressure plate 16 is provided on the side of the lifting block 17 near the movable side plate 9. A second through-hole 18 corresponding to the first through-hole 13 is opened on the surface of the movable side plate 9. A second motor 10 is provided on the top of the fixed side plate 8. The output shaft of the second motor 10 is connected to one end of the second threaded rod 11. A support plate 15 is provided on the bottom side of the movable side plate 9 near the fixed side plate 8. A through groove 14 for the support plate 15 to slide through is opened on the surface of the fixed side plate 8. The composite tube to be processed is placed on the top of the support plate 15.

[0022] The bottom of the movable side plate 9 is provided with a slider 22, and the top of the base plate 5 is provided with a groove 19 for the slider 22 to slide into. A third threaded rod 21 is rotatably provided in the groove 19. The slider 22 is threadedly sleeved on the outside of the third threaded rod 21. A third motor 20 is provided on the outer surface of the base plate 5. The output shaft of the third motor 20 is connected to one end of the third threaded rod 21. The length direction of the third threaded rod 21 is perpendicular to the length direction of the first guide rod 3.

[0023] The width of the groove 2 is greater than the length of the moving seat 4. This design makes it easier for the waste generated during pipe cutting to fall into the waste bin, preventing the waste from falling on the top surface of the workbench 1 and increasing the need for manual cleaning.

[0024] The fixed side plate 8, the movable side plate 9, the support plate 15, and the pressure plate 16 are all provided with a rubber layer on the side surface near the composite pipe.

[0025] Specifically, in use, the composite tube is placed on the support plate 15, and then the third motor 20 is started. The third motor 20 drives the third threaded rod 21 to rotate, which in turn moves the slider 22, thereby moving the movable side plate 9 towards the fixed side plate 8. During this process, the support plate 15 can pass through the through groove 14, and the pressure plate 16 also passes through the second through port 18, until the composite tube is clamped between the fixed side plate 8 and the movable side plate 9. Figure 2 As shown, the second motor 10 is then started, driving the second threaded rod 11 to rotate. In conjunction with the action of the second guide rod 12, the lifting block 17 is moved downward, which in turn moves the pressure plate 16 downward until the pressure plate 16 abuts against the upper part of the outer surface of the composite pipe, so that the composite pipe is clamped between the pressure plate 16 and the support plate 15. The stability of the composite pipe clamping and fixing is improved by setting rubber layers at multiple positions. This device not only meets the processing requirements of composite pipes of different lengths, but is also suitable for pipes of different diameters. Moreover, it is simple and convenient to operate, greatly improving the applicability and practicality of the device, and is worth promoting and using.

[0026] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
