Description

Technical Field

[0001] This utility model belongs to the field of aluminum tube processing, and specifically relates to an aluminum tube dotting machine. Background Technology

[0002] Aluminum tubes are a type of non-ferrous metal tube, widely used in industries such as automobiles, ships, aerospace, aviation, electrical appliances, agriculture, electromechanical, and home furnishings. During the processing of aluminum tubes, it is often necessary to perform a dotting operation on the aluminum tubes.

[0003] The prior art discloses an aluminum tube marking machine, authorized by announcement number CN208004578U. It includes a frame, a motor, a marking device, and a control panel. The marking device includes a limiting plate, a marking mechanism, and an aluminum tube limiting mechanism. The marking mechanism includes a driven shaft, a driven plate, and marking devices. A transmission belt is connected to the driven shaft. Four rectangular limiting blocks are connected to the end face of the driven plate away from the driven shaft. A circular limiting hole is formed in the center of each limiting block along the radial direction of the driven shaft. A cylindrical marking device 16 passes through each limiting hole in the limiting block. The end of the marking device near the axis of the driven shaft has a conical tip, and the end away from the axis of the driven shaft has a rounded corner that abuts against the limiting plate. A circular end face of the limiting plate away from the transmission belt, near the circumference of the limiting plate 13, is connected to... Four arc-shaped blocks have the same curvature on their outer sidewalls away from the driven shaft 14 axis as the circumferential sidewalls of the limiting plate. Each arc-shaped block has an arc surface on its end face facing the driven shaft axis. The distance from the arc surface to the outer circumferential sidewall of the arc-shaped block gradually increases from small to large. The end with the larger distance is the head of the arc-shaped block, and the end with the smaller distance is the tail of the arc-shaped block. The four arc-shaped blocks are connected head to tail in sequence to form a complete circumference. The driven shaft drives the driven plate to rotate coaxially, and the driven plate drives the four arc-shaped blocks to rotate coaxially. Each arc-shaped block drives the dotting device inserted in it to rotate coaxially. The rounded corner of the dotting device abuts against the arc surface of the arc-shaped block to move circumferentially. Therefore, while the dotting device rotates along the axis of the driven shaft, it also moves back and forth along the radial direction of the driven shaft, thereby realizing the dotting processing of the aluminum tube.

[0004] However, in the above solution, after the aluminum tube is assembled, there is no support structure inside the tube corresponding to the dotting device. In addition, combined with the characteristics of the aluminum tube itself, the relatively thin aluminum tube is prone to local deformation after being hit. Utility Model Content

[0005] To overcome the above shortcomings, the present invention provides an aluminum tube dotting machine, which aims to improve the problem that aluminum tubes are prone to deformation after being hit.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an aluminum tube dotting machine, comprising: a base plate, a support column fixedly connected above the base plate, a support component fixedly connected on the right side, the support component being perpendicular to the base plate, a flat plate fixedly connected to the upper end of the support component, the flat plate being parallel to the base plate. An opening is provided on the support component, a bearing is provided inside the opening, and a support arm fixedly connected to the inner wall of the bearing is provided, the support arm being rotatable;

[0007] The surface of the support arm is provided with an elongated notch, and a support rod is slidably connected inside the elongated notch. There is an arc-shaped plate at the top and bottom of the support arm, and the arc-shaped plate is fixedly connected to the support rod.

[0008] Furthermore, the support rod is a telescopic column, divided into a positioning support rod and an elastic support rod, both of which include a sleeve and an inner column. The sleeve and the inner column are slidably connected, and the sleeve is fixedly connected to one end of the arc plate that is close to each other. This can fix the position of the arc plate and allow the arc plate to slide along the long notch.

[0009] Furthermore, a locking disc is installed on the inner column of the positioning support rod. The locking disc is connected to the inner column by a thread. When the locking disc is locked, it can fix the position of the sleeve, thereby adjusting the distance between the arc plate and the support arm.

[0010] Furthermore, the sleeve of the elastic support rod has a fixedly connected spring on the side away from the arc plate. The spring can provide a thrust to the side of the arc plate that is close to each other, thereby supporting the inner wall of the aluminum tube.

[0011] Furthermore, the plate is provided with a dotting mechanism on the side near the bottom plate, which consists of a cylinder and an electric telescopic rod. The cylinder is fixedly connected to the plate, and dots can be made on the aluminum tube through the dotting mechanism.

[0012] Furthermore, a horizontal plate is provided at one end of the curved plate near the supporting component. The horizontal plate can position the aluminum tube and prevent it from slipping.

[0013] Furthermore, a flange is fixed at one end of the support arm near the supporting component, and a short bushing is fixed on the supporting component. A disc is fixedly connected to the short bushing, and a semi-circular groove is opened on the disc. A slider is fixedly connected to the flange. The disc and the flange are slidably connected, which allows the support arm to rotate up to 180° along the axial direction.

[0014] In use, the aluminum tube is fitted over the curved plate. The distance between the curved plate and the support arm is adjusted by adjusting the locking disc on the positioning support rod. The elastic support rod supports the curved plate through the spring force, thus enabling the curved plate to support the aluminum tube. The height and position of the support column are adjusted so that it can support the side of the aluminum tube that is not marked. The device is connected to a power source and controlled by a switch. Activating the electric telescopic rod causes the motor to rotate, which in turn moves the push rod outward. The impact head marks the aluminum tube. The horizontal plate on the curved plate prevents the aluminum tube from exceeding the position of the curved plate. The curved plate moves within the long notch through the support rod. At the same time, the aluminum tube can be rotated 180° along the axis without disassembling it using the flange and disc, allowing the impact head to mark different positions on the aluminum tube. The marking position can be confirmed by the scale strip. The marking range should not exceed the length of the curved plate. Because the curved plate provides internal support, it not only fixes the position of the aluminum tube but also prevents the aluminum tube from deforming due to impact.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the distance between the arc plate and the support arm can be controlled by the locking plate, so that the arc plate can support the aluminum tube and prevent the aluminum tube from deforming when striking. It solves the problem that it is not convenient to support the inner wall of aluminum tubes of different sizes, which makes the aluminum tube easy to deform after being hit, and thus makes it difficult for the aluminum tube to maintain its round shape. At the same time, by moving the arc plate, the striking head can strike any position on the aluminum tube without exceeding the length range of the arc plate. The design is reasonable and the structure is simple, which can improve accuracy and efficiency. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to an electrical connection; they can refer to a hydraulic connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0026] See Figures 1-6An aluminum tube dotting machine includes a base plate 1, two fixedly connected support columns 14 on the top of the base plate 1, four bases 21 below the base plate, a fixedly connected support component 2 on the right side of the base plate, the support component 2 being perpendicular to the base plate 1, the support component being either a vertical plate or a vertical arm, and a fixedly connected flat plate 3 at the top of the support component 2, the flat plate 3 being parallel to the base plate 1.

[0027] The support component 2 has an opening, and a bearing 18 is placed inside the opening. A support arm 6 is fixedly connected to the inner ring of the bearing 18. The support wall 6 extends horizontally, allowing the support arm 6 to rotate. The support component 2 has a fixedly connected short bushing 13. The short bushing 13 is on the same axis as the bearing 18 and the support arm 6. The support arm 6 can pass through the middle of the short bushing 13. The support arm 6 and the short bushing 13 are slidably connected. The surface of the support arm 6 has a long notch, and a support rod is set inside the long notch. A dotting mechanism is provided on the side of the plate 3 near the bottom plate 1. An aluminum tube can be fitted onto the support arm 6, and then the aluminum tube is dotted by the dotting mechanism.

[0028] There is an arc plate 7 on the top and bottom of the support arm 6. A horizontal plate 15 is provided on the support arm 6 near the support component 2. When in use, the aluminum tube can be sleeved on the two arc plates 7 and the end of the aluminum tube can be in contact with the horizontal plate 15. This makes it easy to position the aluminum tube 19 and prevent one end of the aluminum tube 19 from sliding beyond the position of the arc plate 7.

[0029] The aforementioned support rod is a telescopic column composed of a sleeve and an inner column. There are two sleeves, each sleeved at one end of the inner column. The sleeves and the inner column are slidably connected. The support rod is divided into a positioning support rod 11 and an elastic support rod 12, both of which can slide within the elongated notch. The sleeve of the support rod is fixedly connected to the arc plate 7. Since the support rod can move within the elongated notch, the arc plate 7 can also move along the length of the elongated notch. The positioning support rod is connected to both ends of the arc plate 7. The inner column of the positioning support rod 11 is provided with threads and a locking disc 17. The locking disc 17 is connected to the inner column by threads. When the locking disc 17 rotates, the position of the sleeve can be adjusted, thereby adjusting the distance between the arc plate 7 and the support arm 6. At this time, the distance between the two arc plates 7 can also be adjusted.

[0030] There are two elastic support rods 12, and the two elastic support rods 12 have the same structure. A spring 16 is sleeved on the inner column of the elastic support rod 12. The spring 16 is located between the sleeve and the support arm 6, and the two ends of the spring 16 are connected to the sleeve and the support arm 6 respectively. This spring 16 will generate a restoring force after being stretched. When the aluminum tube is sleeved on the two arc plates 7, the two arc plates 7 can be moved in opposite directions by rotating the locking plate 17. Finally, the arc plates 7 provide internal support for the aluminum tube. When it is necessary to remove the aluminum tube, the locking plate 17 can be rotated in the opposite direction. At this time, under the action of the spring 16, the two arc plates 7 move in the direction of approaching each other, so that the arc plates 7 no longer support the aluminum tube, and the aluminum tube can be removed.

[0031] In addition, there is a scale strip on the side of the support arm 6 near the support component 2, which can determine the distance between two adjacent marked positions. In order to ensure the stability of the arc plate 7 when it is translated, a limit plate is fixed on each inner column. There are two limit plates, and the two limit plates are located above and below the support arm 6 respectively. At this time, the support arm 6 is located in the middle position of the inner column. The outer diameter of the two limit plates is larger than the width of the long strip notch, so that the inner column can slide in the long strip notch, but the inner column cannot be pulled out from the long strip notch.

[0032] Since the aluminum tube may require multiple points for marking, a flange 10 is fixedly connected at one end of the support arm 6 near the short bushing. However, the flange 10 is not located at the end of the support arm 6. A fixedly connected disc 22 is provided on the short bushing 13. A semi-circular slot is provided on the end face of the disc 22. A fixedly connected slider is provided on the flange 10. The flange 10 and the disc 22 are slidably connected through the slider and the groove. At this time, the support arm 6 can rotate up to 180°. A radially extending threaded hole is provided on the short bushing 13. A threaded locking rod is screwed into this threaded hole. By turning the threaded locking rod, the position of the support arm 6 can be locked.

[0033] Finally, in this embodiment, the dotting mechanism consists of a cylinder 5 and a push rod 8. The cylinder 5 has reinforcing strips 4 fixedly connected to both sides. The bottom end of the reinforcing strips 4 is fixedly connected to the plate 3, making the dotting mechanism more stable. The cylinder 5 has an opening at one end near the arc plate 7, which allows the push rod 8 to extend.

[0034] A drive mechanism is fixedly connected to the inner wall of the cylinder 5. The drive mechanism can control the push rod 8 to reciprocate within a certain range. The drive mechanism can be an electric telescopic rod. The model of the electric telescopic rod can be the electric telescopic rod produced by Changzhou Luyi Electric Push Rod Co., Ltd., with the product model SXTL. A striker 9 can be installed at the lower end of the push rod. According to specific needs, different strikers 9 can be replaced to mark the aluminum tube 19.

[0035] The aforementioned support column 14 provides support for the aluminum tube. The support column 14 also has a telescopic structure. Its lower end is fixed to the base plate, and its upper end can move vertically. When its upper end contacts the outer surface of the aluminum tube, its overall length can be locked. The support column 14 can be an electric push rod or other components with a telescopic structure and lockable length.

[0036] The working principle of this utility model is as follows:

[0037] In use, the aluminum tube 19 is fitted over the arc-shaped plate 7. The distance between the arc-shaped plate 7 and the support arm 6 is adjusted by adjusting the locking disc 17 on the positioning support rod 11. The elastic support rod 12 supports the arc-shaped plate 7 through the thrust of the spring 16, thereby enabling the arc-shaped plate 7 to support the aluminum tube 19. The height and position of the support column 14 are adjusted so that it can support the side of the aluminum tube 19 that is not marked. The device is connected to a power source and controlled by a switch. The electric telescopic rod is started, causing the motor 20 to work, which in turn causes the push rod 8 to reciprocate. The impact head 9 then supports the aluminum tube 19. The aluminum tube 19 is prevented from exceeding its position by the horizontal plate 15 on the arc plate 7. The arc plate 7 moves within the long notch via the support rod. At the same time, the aluminum tube 19 can be rotated 180° along the axis without disassembling it via the flange 10 and the disc 22, so that the impact head 9 can make impacts at different positions on the aluminum tube 19. The impact position can be confirmed by the scale strip. The impact range must not exceed the length of the arc plate 7. Since the arc plate 7 provides internal support, it not only fixes the position of the aluminum tube 19 but also prevents the aluminum tube 19 from being deformed by impact.

[0038] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this invention. Therefore, the protection scope of this utility model should be primarily defined by the scope of the claims.
