Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Combined with reference Figure 1-Figure 5The utility model provides a polishing device for metal products, including a base 1 and a side plate 2 fixedly connected to one side of the base 1, a lifting platform 3 is provided with a support assembly 4 for rolling the tubular metal product, and the lifting platform 3 is also provided with a rotating device 5 for driving the tubular metal product to rotate through the support assembly 4, and one side of the side plate 2 is provided with an inner polishing roller 6 and an outer polishing roller 7 for polishing the inner and outer walls of the tubular metal product. In this application, half of the length of the columnar metal product is smaller than the length of the inner polishing roller 6 or the outer polishing roller 7, so that the end position of the columnar metal product of a certain length can be adjusted, and the surface of the columnar metal product can be fully polished. A lifting assembly 8 for lifting the outer polishing roller 7 is provided on the side plate 2, and a rotation drive structure 9 is provided on the other side of the side plate 2. The rotation drive structure 9 is used to synchronously drive the inner polishing roller 6 and the outer polishing roller 7 to rotate.

[0024] A telescopic device 10 is fixedly connected to the bottom of the base 1, and the output end of the telescopic device 10 movably passes through the base 1 and is fixedly connected to the bottom position of the lifting platform 3. In the present application, the telescopic device 10 adopts a telescopic motor, and the number can be two groups, so that the lifting platform 3 can be controlled to continue to adjust its height.

[0025] There are four groups of support assemblies 4, each group of support assemblies 4 includes a rotating support 41 bolted to the upper surface of the lifting platform 3 and a roller 42 rotatably connected to the rotating support 41 for supporting tubular metal products. Two pairs of rollers 42 can be used to support tubular metal products, and the telescopic device 10 provides a lifting ability for the position of the rollers 42, so that the position of the tubular metal products and the inner polishing roller 6 can be conveniently controlled to contact and correspond.

[0026] The lifting platform 3 is provided with a plurality of mounting holes 11 for bolt connection. The mounting holes 11 can be used to adjust the position of the rotating support 41, so that the spacing between the rollers 42 can be adjusted to meet the diameter requirements of the rolling support of different tubular metal products.

[0027] The output end of the rotating device 1 5 is provided with a gear pair 2 12, and the rotating device 1 5 is connected to one of the rollers 42 through the gear pair 2 12. The gear pair 2 12 can be composed of a pair of mutually meshing cylindrical gears. The rotating device 1 5 can use a rotating motor, which can drive the roller 42 to rotate through the gear pair 2 12, so that the tubular metal product on the roller 42 can be polished and rotated.

[0028] The lifting assembly 8 includes a screw rod 81 threadedly connected to the side plate 2, a slide seat 82 rotatably connected to one end of the screw rod 81, and a rotating handle 83 fixedly connected to the other end of the screw rod 81. A slide groove for the slide seat 82 to slide is provided on the side plate 2. The outer polishing roller 7 is rotatably connected to the slide seat 82 via a rotating shaft 1, and the inner polishing roller 6 is rotatably connected to the side plate 2 via a rotating shaft 2. One end of the screw rod 81 can be connected to the slide seat 82 via a bearing.

[0029] Specifically, by rotating the handle 83 to rotate the screw rod 81, the slide seat 82 can drive the outer polishing roller 7 to change its height under the sliding limit in the slide groove, so as to adjust the spacing facing or back to the position of the inner polishing roller 6 to adapt to the fit of polishing on the outer surface of the tubular metal product.

[0030] The rotary drive structure 9 includes a fixing frame 91 fixedly connected to the side plate 2, a fixing frame 92 fixedly connected to the slide 82, a pair of gear pairs 93 arranged on the inner side of the fixing frame 91, a telescopic transmission member 94 connected to the pair of gear pairs 93, and a rotating device 95 fixedly connected to the side plate 2. The rotating device 95 is connected to one of the gear pairs 93 in a transmission manner. The gear pair 1 in the present application is composed of a pair of mutually meshing bevel gears, which can be used to adjust the transmission direction. The rotating device 95 can also use a rotary motor.

The limit rod 942 and the limit bar 943 are both slidably inserted into the transmission tube 941. The advantage of setting the limit bar 943 is that when the limit rod 942 and the transmission tube 941 are slidably matched, the transmission tube 941 can drive the limit rod 942 to rotate in real time.

[0032] Specifically, by controlling the driving of the second rotating device 95, the second rotating device 95 can drive the inner polishing roller 6 and the transmission tube 941 to rotate through the gear pair 1 93 therein, and the rotation of the transmission tube 941 can drive another gear pair 93 to rotate through the limit bar 943 and the limit rod 942, so that the outer polishing roller 7 can also rotate synchronously with the inner polishing roller 6. When the outer polishing roller 7 and the inner polishing roller 6 are fitted and limited on the inner and outer walls of the tubular metal product, the rotation of the tubular metal product is controlled in an opposite direction to the rotation direction of the outer polishing roller 7, so that the inner and outer walls of the tubular metal product can be polished at the same time; when the outer polishing roller 7 or the inner polishing roller 6 cannot meet the polishing length requirement of the tubular metal product, the end position of the tubular metal product can be changed by replacement, so that the polishing position can be polished.
