Description

Technical Field

[0001] This utility model relates to the field of polishing, and more specifically to a metal polishing structure. Background Technology

[0002] When metal is exposed to air for a long time, its surface will rust, forming a rust layer. This rust layer needs to be removed before use, especially when welding on the metal surface, to ensure weld quality. Rectangular metal tubes are commonly used pipe materials. Surface grinding of rectangular tubes is mostly done manually, which is inefficient and time-consuming. Utility Model Content

[0003] This invention provides a metal polishing structure that can automatically and quickly polish the surface of a rectangular tube, saving time and effort.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows:

[0005] A metal polishing structure includes a horizontally arranged frame with two symmetrically connected support seats inside the frame. Both ends of the two support seats have rotatable side wheels. The lower end of each side wheel is provided with a support for supporting the polishing body. A portal frame is fixed at the upper end of the frame. A transmission wheel rotates in the middle of the portal frame. A central shaft is coaxially limited and passes through the transmission wheel. A polishing plate is fixed at the lower end of the central shaft to polish the upper surface of the polishing body.

[0006] The frame contains a bidirectional screw that rotates within it, and two support seats are threadedly connected to the two ends of the bidirectional screw.

[0007] A spring is provided between the transmission wheel and the grinding plate, which causes the grinding plate to move downward and press against the upper end face of the grinding body.

[0008] The upper end of the central shaft is coaxially fixed with a shaft head, and a support plate is rotatably mounted on the shaft head.

[0009] A sliding rod is vertically fixed to the lower end face of the support arm plate, and the sliding rod passes through the portal frame.

[0010] An electric telescopic rod is fixed to the side end of the gantry frame. When the electric telescopic rod extends, it can push the support arm plate upward.

[0011] The frame has two support legs at its lower end.

[0012] The outer surface of the side wheel is provided with an elastic rubber layer.

[0013] Both ends of the bidirectional screw are equipped with adjustment knobs. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] The following is combined with Figure 1-6 Explanation:

[0023] A metal polishing structure includes a horizontally arranged frame 1, with two symmetrically connected support seats 10 inside the frame 1. Side wheels 11 are rotatably mounted at both ends of the two support seats 10. Each side wheel 11 has a support edge 12 at its lower end for supporting the polishing body. A portal frame 2 is fixed at the upper end of the frame 1. A transmission wheel 5 is rotatably mounted in the middle of the portal frame 2. A central shaft 6 is coaxially limited and passes through the transmission wheel 5. A polishing plate 7 is fixed at the lower end of the central shaft 6 to polish the upper surface of the polishing body.

[0024] During polishing, the rectangular tube is inserted between the two support seats 10 and the two side wheels 11. The lower end of the rectangular tube is supported by the support edge 12 at the lower end of the side wheel 11. Thus, the rectangular tube is lifted by the four support edges 12. At this time, the lower end of the polishing plate 7 contacts the upper end of the rectangular tube. Then, the first motor installed on the gantry frame 2 is started to drive the transmission wheel 5, which in turn drives the polishing plate 7 to rotate through the central shaft 6, thus polishing the upper end of the rectangular tube. Then, by pushing the rectangular tube backward, the rectangular tube moves backward between the four side wheels 11, thus continuously polishing the upper end of the rectangular tube. This forms an automatic and fast polishing of the rectangular tube surface, saving time and effort.

[0025] Meanwhile, the side wheels 11 facilitate pushing the rectangular tube backward.

[0026] Further:

[0027] A bidirectional screw 13 rotates within the frame 1, and two support seats 10 are threadedly connected to the two ends of the bidirectional screw 13.

[0028] By rotating the bidirectional screw 13, the two support seats 10 can be moved closer or further apart by the threaded drive, thereby adjusting the distance between the side wheels 11 on both sides, so as to adapt to the grinding of rectangular tubes of different widths.

[0029] Further:

[0030] A spring (not shown in the figure) is provided between the transmission wheel 5 and the grinding plate 7, so that the grinding plate 7 moves downward and presses against the upper end surface of the grinding body.

[0031] During polishing, first push the polishing plate 7 upward to make the space between the polishing plate 7 and the side wheel 11 large enough for the rectangular tube to be placed. After inserting the rectangular tube between the two side wheels 11 and supporting it with the four support edges 12, release the polishing plate 7. The spring force will cause the polishing plate 7 to press down against the upper end face of the polishing body, thereby enabling the polishing body to make close contact with the upper end face of the rectangular tube for polishing, while adapting to the polishing of rectangular tubes of different heights.

[0032] like Figure 1-6 As shown:

[0033] The upper end of the central shaft 6 is coaxially fixed with a shaft head, and a support plate 8 is rotatably mounted on the shaft head.

[0034] The support arm plate 8 facilitates the lifting of the grinding plate 7.

[0035] Further:

[0036] A sliding rod 9 is vertically fixed to the lower end face of the support arm plate 8. The sliding rod 9 passes through the portal frame 2 to limit the support arm plate 8, thereby facilitating the upward pushing of the support arm plate 8 in a fixed position.

[0037] Further:

[0038] An electric telescopic rod 4 is fixed to the side end of the gantry frame 2. When the electric telescopic rod 4 is extended, it can push the support arm plate 8 to move upward.

[0039] The extension of the electric telescopic rod 4 can push the support arm plate 8 upward, thereby raising the grinding plate 7, which can automatically raise the grinding plate 7, making it easier to insert the rectangular tube between the two side wheels 11.

[0040] like Figure 1-6 As shown:

[0041] Two support plates 3 are provided at the lower end of the frame 1 to support the equipment.

[0042] like Figure 1-6 As shown:

[0043] By providing an elastic rubber layer on the outer surface of the side wheel 11, when grinding debris enters between the side wheel 11 and the rectangular tube, the elastic rubber layer on the surface of the side wheel 11 can deform, allowing the rectangular tube to move smoothly backward between the two side wheels 11.

[0044] like Figure 1-6 As shown:

[0045] The bidirectional screw 13 is equipped with adjustment knobs at both ends, which facilitates the rotation control of the bidirectional screw 13.

[0046] Of course, the above description is not a limitation of this instruction manual, and this utility model is not limited to the examples mentioned above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model are also within the protection scope of this utility model.
