Description

Technical Field

[0001] This utility model relates to the field of metal square tube processing technology, specifically a square tube end face flattening machine. Background Technology

[0002] Square steel pipe is a type of pipe with a square or rectangular cross-section. It is made from strip steel through a process that includes unpacking, flattening, rolling, and welding to form a round pipe. The round pipe is then rolled into a square pipe and cut to the required length. After cutting, the end face of the square pipe may have bevels or burrs. In this case, a leveling machine is needed to grind the end face of the square pipe to make it smooth.

[0003] The existing technology, patent publication number CN220007105U, describes a stainless steel pipe end face leveling device for high-speed rail components. This patent involves a sliding plate connected to a sliding frame, with a threaded screw rotating and moving downwards. With the cooperation of a bearing seat, the sliding plate moves along the sliding frame, and a pressing frame below presses down on the stainless steel pipe to prevent it from shaking during grinding. However, in actual use, this device still has the following shortcomings: the grinding force of the grinding disc on the pipe end face is difficult to control, potentially leading to excessive or insufficient force during grinding, further affecting the flatness and processing quality of the end face. Furthermore, when the grinding disc needs to be replaced due to wear, the existing fixing method often makes disassembly and replacement cumbersome and complex, not only time-consuming and labor-intensive but also potentially causing excessive downtime, affecting production efficiency and processing costs.

[0004] Therefore, a square tube end face flattening machine is needed to solve the problems in the existing technology where it is difficult to control the grinding force when flattening the end face of square tubes, and the grinding disc is not easy to disassemble and replace quickly after wear. Utility Model Content

[0005] The purpose of this utility model is to provide a square tube end face flattening machine to solve the problems in the prior art that the grinding force is difficult to control when flattening the end face of square tubes, and that the grinding disc is not easy to disassemble and replace quickly after wear.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a square tube end face flattening machine, including a worktable, a fixing mechanism provided on the left side of the top surface of the worktable, a rotating seat and a second motor installed on the right side of the top surface of the worktable, a movable rod rotatably installed inside the rotating seat, a disassembly assembly provided on the left outer wall of the movable rod, a grinding head installed on the movable rod through the disassembly assembly, a driven transmission wheel coaxially fixedly connected to the right outer wall of the movable rod, and a driving transmission wheel coaxially fixedly connected to the output end of the second motor;

[0007] The fixing mechanism includes a support platform, the top surface of which has a sliding groove, and a bidirectional lead screw is rotatably connected between the two end walls inside the sliding groove. Two symmetrically distributed sliders are threaded onto the outer surface of the bidirectional lead screw, and clamping blocks are fixedly connected to the top surfaces of the two sliders. A first motor is installed on the outer wall of the front end of the support platform.

[0008] The solution specifies that the assembly / disassembly component includes an mounting block, which is coaxially fixedly connected to the left outer wall of the movable rod. The mounting block has a U-shaped groove inside, with springs fixedly connected to both ends of the U-shaped groove. A movable plate is fixedly connected to the end of the spring furthest from the U-shaped groove. A fixing block is fixedly connected to the middle of the outer wall of the movable plate furthest from the spring. A protrusion is fixedly connected to the top of the outer wall of the movable plate furthest from the spring. A rotating shaft is rotatably connected between the top and bottom surfaces at the center of the longitudinal section inside the U-shaped groove. A rotating plate is fixedly connected to the outer surface of the rotating shaft. A knob is rotatably connected to the top of the rotating shaft, passing through the top surface of the mounting block and coaxially fixedly connected to it.

[0009] It is worth noting that an electric actuator is installed on the bottom surface of the workbench, and a connecting block is fixedly connected to the output end of the electric actuator. A movable slot is provided through the left side of the top surface of the workbench.

[0010] Furthermore, it should be noted that a slot is provided at the center of the left outer wall of the mounting block, and a rod is inserted into the slot. Both ends of the rod have fixing grooves that are compatible with the fixing block.

[0011] In a preferred embodiment, both sliders are slidably engaged with the slide groove, the output end of the first motor rotates through the front wall of the slide groove and is coaxially fixedly connected to the front outer wall of the bidirectional lead screw, and the driven transmission wheel and the driving transmission wheel are connected by a transmission belt.

[0012] In a preferred embodiment, the connecting block is slidably engaged with the movable groove and its top surface is fixedly connected to the bottom surface of the support platform. The left outer wall of the insertion rod is coaxially fixedly connected to the right outer wall of the grinding head. The two fixing blocks respectively slide through the inner end walls of the slot and are inserted into the corresponding fixing grooves.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The electric actuator pulls the support platform to move, causing the tube clamped and fixed on the support platform to move slowly in the direction of the rotating grinding head. This makes it easier to control the grinding force of the square tube to flatten it, thereby improving the flatness of the square tube end face and effectively avoiding the problem of difficulty in controlling the grinding force when flattening the square tube end face.

[0015] 2. By using the disassembly and assembly components, turning the knob drives the rotating plate to rotate. The rotating plate presses against the protrusion, causing the moving plate to separate the fixed block from the fixed groove, thus releasing the fixation of the grinding head. After inserting the insert rod on the replaced grinding head into the slot, releasing the knob pushes the fixed block into the fixed groove under the action of the spring, completing the replacement of the grinding head. The operation is simple and effectively avoids the problem of not being able to quickly disassemble and replace the grinding disc after it is worn. Attached Figure Description

A first motor 26 is installed on the outer wall of the front end of the support platform 21.

[0024] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth noting that the disassembly and assembly component 6 includes a mounting block 61, which is coaxially fixedly connected to the left outer wall of the movable rod 5. A U-shaped groove 62 is provided inside the mounting block 61. Springs 63 are fixedly connected to both ends of the U-shaped groove 62. A movable plate 64 is fixedly connected to the end of the spring 63 away from the U-shaped groove 62. A fixing block 65 is fixedly connected to the middle of the outer wall of the end of the movable plate 64 away from the spring 63. A protrusion 66 is fixedly connected to the top of the outer wall of the end of the movable plate 64 away from the spring 63. A rotating shaft 67 is rotatably connected between the top and bottom surfaces at the center of the longitudinal section inside the U-shaped groove 62. A rotating plate 68 is fixedly connected to the outer surface of the rotating shaft 67. A knob 69 is rotatably connected to the top surface of the mounting block 61 at the top of the rotating shaft 67.

[0025] Further as Figure 2 and Figure 3 As shown, it is worth noting that an electric actuator 10 is installed on the bottom surface of the workbench 1, and a connecting block 11 is fixedly connected to the output end of the electric actuator 10. A movable slot 12 is provided through the left side of the top surface of the workbench 1.

[0026] Further as Figure 4 As shown, it is worth noting that a slot 13 is provided at the center of the outer left side of the mounting block 61, and a rod 14 is inserted into the slot 13. The outer walls of both ends of the rod 14 are provided with fixing grooves 15 that are compatible with the fixing block 65.

[0027] Further as Figure 2 and Figure 3As shown, it is worth noting that both sliders 24 are slidably engaged with the slide groove 22, which improves the stability of the sliders 24 when they are driven to move by the bidirectional lead screw 23. The output end of the first motor 26 rotates through the front wall of the slide groove 22 and is coaxially fixedly connected with the front outer wall of the bidirectional lead screw 23, providing a power source for the rotation of the bidirectional lead screw 23. The driven transmission wheel 8 and the driving transmission wheel 9 are connected by a transmission belt, which facilitates the second motor 4 to drive the movable rod 5 to rotate.

[0028] Further as Figure 2 and Figure 4 As shown, it is worth noting that the connecting block 11 slides into the movable slot 12 and its top surface is fixedly connected to the bottom surface of the support platform 21, which facilitates the electric push rod 10 to drive the support platform 21 to move towards the grinding head 7 through the connecting block 11. The left outer wall of the insertion rod 14 is coaxially fixedly connected to the right outer wall of the grinding head 7. Through the cooperation between the insertion rod 14 and the slot 13, it is convenient to quickly disassemble and replace the grinding head 7. The two fixing blocks 65 slide through the inner end walls of the slot 13 and are inserted into the corresponding fixing slots 15 to lock the insertion rod 14 and prevent the insertion rod 14 from accidentally separating from the slot 13.

[0029] In summary: When using this device, firstly, the end of the square tube to be processed is placed on the top surface of the support platform 21. Then, the first motor 26 is turned on to drive the bidirectional lead screw 23 to rotate. Under the action of the thread, the bidirectional lead screw 23 drives the two sliders 24 to move closer to each other. The two sliders 24 respectively drive the two clamping blocks 25 to move closer to each other, clamping and fixing both ends of the square tube. At the same time, the second motor 4 is turned on to drive the active transmission wheel 9 to rotate. The active transmission wheel 9 drives the driven transmission wheel 8 to rotate. The driven transmission wheel 8 drives the grinding head 7 to rotate synchronously through the movable rod 5. Then, the electric push rod 10 is turned on. The electric push rod 10 pulls the support platform 21 and the clamped square tube slowly towards the grinding head 7 through the connecting block 11 to grind the end face of the square tube that needs to be flattened. By controlling the stroke of the electric push rod 10, it is easy to control the grinding force of the square tube to flatten it, thereby improving the flatness of the end face of the square tube and effectively avoiding the problem of difficulty in controlling the grinding force when flattening the end face of the square tube.

[0030] When the grinding head 7 on the leveling machine needs to be replaced, the operator turns the knob 69 to drive the rotating shaft 67 to rotate. The rotating shaft 67 drives the rotating plate 68 to rotate. The two ends of the rotating plate 68 press against the two protrusions 66 respectively. After the two protrusions 66 are under force, they push the two moving plates 64 to drive the two fixed blocks 65 to separate from the two fixed slots 15. The spring 63 is in a state of contraction under force. At this time, the locking of the insertion rod 14 is released. The operator can remove the insertion rod 14 from the inside of the slot 13, thereby realizing the disassembly of the grinding head 7. Then, the insertion rod 14 on the replaced grinding head 7 is inserted into the slot 13. After releasing the knob 69, the fixed block 65 is pushed into the fixed slot 15 under the elastic action of the spring 63, completing the replacement of the grinding head 7. The operation is simple and effectively avoids the problem of not being able to quickly disassemble and replace the grinding disc after it is worn.

[0031] The first motor 26, the second motor 4, and the electric actuator 10 can be purchased from the market. The first motor 26, the second motor 4, and the electric actuator 10 are equipped with power supplies. This is a mature technology in the field and has been fully disclosed. Therefore, it will not be repeated in the specification.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
