Description

Technical Field

[0001] This utility model relates to the field of polishing machine technology, and in particular to an external cylindrical polishing machine for metal tube processing. Background Technology

[0002] The external cylindrical grinding machine for metal tube processing is a specialized piece of equipment used for precision grinding and polishing of the outer surface of metal tubes. This equipment uses rotating grinding wheels or polishing wheels to rub the surface of the metal tube, removing defects such as burrs, oxide layers, rust, and scratches, so that the surface of the metal tube can achieve a higher degree of flatness and smoothness.

[0003] When processing metal tubes, if the length of the metal tube is too long, one side of the metal tube will detach from the equipment after processing. Without support on one side, the metal tube will vibrate, affecting the processing effect. Therefore, there is a need for an external cylindrical grinding machine for processing metal tubes to smoothly lift the metal tube and avoid uneven force on the metal tube, which would cause vibration during processing. Utility Model Content

[0004] The purpose of this utility model is to provide an external cylindrical grinding machine for metal tube processing, in order to solve the problem mentioned in the background art, where, if the length of the metal tube is too long during processing, one side of the metal tube will detach from the equipment after processing. Without the support force on one side, the metal tube will vibrate, affecting the processing effect.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an external cylindrical grinding machine for metal tube processing, comprising:

[0007] External cylindrical polishing machine body;

[0008] The guide assembly includes a trapezoidal plate, a baffle, a connecting frame, a connecting frame, a connecting shaft, and a roller. The baffle is fixed to the outer surface of one end of the trapezoidal plate, the connecting frame is fixed to the lower surface of one side of the trapezoidal plate, the connecting frame is fixed to the upper surface of the connecting frame, the connecting shaft is fixed inside the connecting frame, and the roller is rotatably connected to the outer surface of the connecting shaft. The roller is located on the other side of the outer cylindrical polishing machine body.

[0009] Furthermore, a movable frame is fixed to the other end of the upper surface of the trapezoidal plate, and a movable column is slidably connected inside the movable frame.

[0010] Furthermore, a movable plate is fixed to the outer surface of one end of the movable column, and a guide column is fixed to the upper surface of the movable column, with the guide column penetrating and connected to the top of the movable frame.

[0011] Furthermore, it also includes an adjustment assembly, which includes a base plate, a support frame, a movable column, a limiting groove, and a limiting plate; the movable column is fixed to the opposite surface of the trapezoidal plate, the support frame is slidably connected to the outside of the movable column, the base plate is fixed to the lower surface of the support frame, the limiting groove is equidistantly opened inside the movable column, and the limiting plate is locked in the limiting groove and inside the top of the support frame.

[0012] Furthermore, a support plate is fixed to the outer surface of the other end of the top of the support frame, a movable rod is slidably connected inside the support plate, the outer surface of the movable rod is fixed to the outer surface of the limiting plate, a connecting column is fixed to the outer surface of the movable rod, and a limiting hole is opened inside the movable rod.

[0013] Furthermore, a fixed rod is connected through the support plate and the moving rod. A guide plate is fixed on the upper surface of the fixed rod, and a spring is fixed on the lower surface of the middle part of the guide plate. The spring is fixed inside the support plate.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] I. This utility model, through the set guide component, after the metal tube is processed by the outer cylindrical polishing machine body, the metal tube moves to the top of the roller. Under the action of the connecting shaft, the roller rotates, causing the metal tube to move to the upper surface of the trapezoidal plate, applying a pushing force to the guide column, driving the movable column to move inside the movable frame. The baffle pushes the metal tube to the baffle, and then the metal tube stored at the baffle is transported to the required position. This solution smoothly lifts the metal tube, avoiding uneven force on the metal tube, which would cause the metal tube to vibrate during processing.

[0016] II. Based on the first beneficial effect, when the height of the trapezoidal plate and roller needs to be adjusted with the help of the adjustment components, an upward force is applied to the guide plate to drive the fixed rod out of the support plate, and a pushing force is applied to the connecting column to move the limiting hole located at the connecting column into the support plate. The force applied to the guide plate is then removed, and under the elastic force of the spring, the fixed rod springs back into the moving rod, driving the limiting plate out of the limiting groove. After the moving column is no longer restricted, a pulling force is applied to the trapezoidal plate to restrict the moving column to the required position. Using the above method, the limiting plate can be pulled back into the corresponding limiting groove and support frame. This solution can more accurately fix the trapezoidal plate at the required height and improve the flexibility of the device. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0029] Please see Figure 1 and Figure 4 As shown, this embodiment is an external cylindrical grinding machine for metal tube processing, comprising:

[0030] External cylindrical polishing machine body 11;

[0031] The guide assembly includes a trapezoidal plate 21, a baffle 22, a connecting frame 23, a connecting frame 24, a connecting shaft 25, and a roller 26. The baffle 22 is fixed to the outer surface of one end of the trapezoidal plate 21, the connecting frame 23 is fixed to the lower surface of one side of the trapezoidal plate 21, the connecting frame 24 is fixed to the upper surface of the connecting frame 23, the connecting shaft 25 is fixed inside the connecting frame 24, and the roller 26 is rotatably connected to the outer surface of the connecting shaft 25. The roller 26 is located on the other side of the outer cylindrical polishing machine body 11.

[0032] The cylindrical grinding machine body 11 is used to grind and polish the outer surface of the metal tube. The trapezoidal plate 21 provides a support surface for bearing and guiding the movement of the metal tube. The baffle 22 is used to block and position the metal tube. The connecting frame 23 is used to connect the connecting frame 24 to the trapezoidal plate 21. The connecting frame 24 is used to receive and install the connecting shaft 25. The connecting shaft 25 is used for the roller 26 to rotate on its surface. The roller 26 is used to receive the metal tube rolling off the cylindrical grinding machine body 11 and transport it to the trapezoidal plate 21.

[0033] A movable frame 27 is fixed to the other end of the upper surface of the trapezoidal plate 21, and a movable column 28 is slidably connected inside the movable frame 27;

[0034] The movable frame 27 is used for the movable column 28 to move within it, and the movable column 28 is used to change the position of the movable plate 29.

[0035] A movable plate 29 is fixed to the outer surface of one end of the movable column 28, and a guide column 291 is fixed to the upper surface of the movable column 28. The guide column 291 is connected to the top of the movable frame 27.

[0036] The movable plate 29 is used to push the metal tube to the baffle 22, and the guide post 291 facilitates the application of pushing force to the movable post 28.

[0037] Working principle: After the metal tube is processed by the outer cylindrical polishing machine body 11, the metal tube moves to the top of the roller 26. Under the action of the connecting shaft 25, the roller 26 rotates, causing the metal tube to move to the upper surface of the trapezoidal plate 21, which applies a pushing force to the guide column 291, driving the movable column 28 to move inside the movable frame 27. The baffle 22 pushes the metal tube to the baffle 22, and then the metal tube stored at the baffle 22 is transported to the required position.

[0038] This step involves smoothly lifting the metal tube to prevent uneven stress on the tube, which could cause vibration during processing.

[0039] Please see Figure 1 , Figure 3 and Figure 4As shown, this embodiment, based on the above embodiment, also includes an adjustment component. The adjustment component includes a base plate 31, a support frame 32, a movable column 33, a limiting groove 34, and a limiting plate 35. The movable column 33 is fixed to the opposite surface of the trapezoidal plate 21, the support frame 32 is slidably connected to the outside of the movable column 33, the base plate 31 is fixed to the lower surface of the support frame 32, the limiting groove 34 is equidistantly opened inside the movable column 33, and the limiting plate 35 is locked in the limiting groove 34 and inside the top of the support frame 32.

[0040] The base plate 31 is used to fix the trapezoidal plate 21 in the required position, the support frame 32 is used to move the movable column 33 inside it, the movable column 33 is used to change the height of the trapezoidal plate 21, and the limiting groove 34 is used to lock the limiting plate 35 and restrict the movement of the movable column 33.

[0041] A support plate 36 is fixed to the outer surface of the other end of the support frame 32. A moving rod 37 is slidably connected inside the support plate 36. The outer surface of the moving rod 37 is fixed to the outer surface of the limiting plate 35. A connecting column 38 is fixed to the outer surface of the moving rod 37. A limiting hole 39 is opened inside the moving rod 37.

[0042] The support plate 36 is used for the moving rod 37 to move horizontally within it. The moving rod 37 is used to change the position of the limiting plate 35. The connecting column 38 facilitates the application of a moving force to the moving rod 37. The limiting hole 39 is used to receive and install the fixing rod 392, thereby fixing the moving rod 37 in the required position.

[0043] A fixed rod 392 is connected through the support plate 36 and the moving rod 37. A guide plate 391 is fixed to the upper surface of the fixed rod 392. A spring 393 is fixed to the lower surface of the middle part of the guide plate 391. The spring 393 is fixed inside the support plate 36.

[0044] The fixed rod 392 is used to lock and unlock the position of the limiting plate 35, the guide plate 391 facilitates changing the position of the moving rod 37, and the spring 393 provides elasticity to make the fixed rod 392 spring back to its original position.

[0045] Working principle: When it is necessary to adjust the height of trapezoidal plate 21 and roller 26, an upward force is applied to guide plate 391 to drive fixed rod 392 to disengage from support plate 36, and a pushing force is applied to connecting column 38 to move limiting hole 39 located at connecting column 38 into support plate 36. The force applied to guide plate 391 is removed, and under the elastic force of spring 393, fixed rod 392 springs back into moving rod 37, driving limiting plate 35 to disengage from limiting groove 34. After moving column 33 is unrestricted, a pulling force is applied to trapezoidal plate 21 to restrict moving column 33 to the required position. Using the above method, limiting plate 35 can be pulled back into the corresponding limiting groove 34 and support frame 32.

[0046] This step allows for more precise fixing of the trapezoidal plate 21 at the required height, improving the flexibility of the device.
