[0020] 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.
[0021] Please see Figures 1-5 In this embodiment of the utility model, a stainless steel pipe end grinding device includes a base 1, a lifting frame 2 is fixedly installed in the middle of the upper surface of the base 1, a housing assembly 3 is installed at the upper end of the lifting frame 2, the lifting frame 2 is a linear module, one end face of the first housing 301 is fixed on the drive seat of the linear module, the housing assembly 3 includes a cylindrical first housing 301 and at least three second housings 302 surrounding the outer wall of the first housing 301, the second housings 302 are hollow cuboid structures, and one end of the second housings 302 is connected to the first housing 301;
[0022] A second motor 7 is installed in the middle of the first housing 301. The output end of the second motor 7 is connected to a drive gear 71. A telescopic arm 4 is connected to the inner slide groove of the second housing 302. A grinding roller 5 is installed on one side of the outer end of the telescopic arm 4, and a first motor 51 for driving the grinding roller 5 to rotate is installed on the other side of the outer end of the telescopic arm 4. An adjustment component 6 is provided between the second housing 302 and the telescopic arm 4 to adjust the telescopic arm 4's extension and retraction relative to the second housing 302.
[0023] The adjusting assembly 6 includes a slide rail 601 installed at the bottom inner side of the second housing 302. A slide block 602 is slidably mounted on the slide rail 601 along its length. A driven gear 603 is provided on one side of the slide rail 601, and a fixed seat 605 is installed on the other side of the slide rail 601. The driven gear 603 is rotatably connected to the inner wall of the first housing 301 through bearings and a shaft, and the driven gear 603 meshes with the driving gear 71. A first toothed pulley 604 is connected to the top shaft of the driven gear 603. A second toothed pulley 606 is rotatably connected to the upper end of the fixed seat 605. A toothed belt 607 is provided between the first toothed pulley 604 and the first toothed pulley 604. The adjusting assembly 6 also includes a pressure block 608 connected to the slide block 602. One side of the toothed belt 607 is clamped and fixed between the slide block 602 and the pressure block 608. The two arms of the slide block 602 are fixedly connected to one end of the telescopic arm 4 by bolts.
[0024] The stainless steel pipe end grinding device also includes two drive mechanisms 8, which are respectively supported at both ends of the bottom of the stainless steel pipe and are used to drive the stainless steel pipe to rotate. The drive mechanism 8 includes a support base 801, and a rotating roller 802 is rotatably connected to both sides of the upper end of the support base 801. A third motor 803 for driving the rotating roller 802 to rotate is installed on one side of the support base 801.
[0025] In this embodiment, the three sets of adjustment components 6 are synchronously driven to extend or retract their respective telescopic arms 4, thereby adjusting the arm length. This allows for grinding of stainless steel pipe ends of different outer diameters, resulting in fast grinding speed and a smoother, more aesthetically pleasing finish, greatly improving work efficiency.
[0026] Specifically, this solution is for grinding the ends of large stainless steel pipes. Due to the large size of the stainless steel pipes, manual grinding alone would take a lot of time and would not improve work efficiency. Therefore, this solution places a drive mechanism 8 at both ends of the bottom of the large stainless steel pipe. The drive mechanism 8 mainly consists of a support base 801, a rotating roller 802, and a third motor 803. Each drive mechanism 8 has at least two rotating rollers 802. The two rotating rollers 802 rotate at the top ends of the support base 801, and the upper outer walls of the two rotating rollers 802 are in close contact with the outer wall of the stainless steel pipe. Therefore, when the rotating rollers 802 rotate, they can drive the stainless steel pipe to rotate. The third motor 803 is connected to one of the rotating rollers 802 through an existing chain assembly or pulley assembly, which can make the rotating roller 802 rotate and drive the stainless steel pipe to rotate.
[0027] This solution also includes a grinding structure on the outside of the open end of the stainless steel pipe. The grinding structure mainly includes a base 1, a lifting frame 2, a housing assembly 3, a telescopic arm 4, a grinding roller 5, an adjustment assembly 6, a second motor 7, and a drive gear 71. The lifting frame 2 is an existing linear lifting module, which can be used to adjust the position and height of the housing assembly 3 so that the center of the housing assembly 3 is at the same horizontal position and height as the center of the stainless steel pipe. The second motor 7 drives the drive gear 71 to rotate. The rotating drive gear 71 will drive the driven gear 603 to rotate, which will force the first toothed pulley 604 to rotate as well. The rotating first toothed pulley 604 will drive the slide 602 to move through the toothed belt 607. The slide 602 will drive the telescopic arm 4 to slide relative to the second housing 302, thereby extending or shortening the movement range of the telescopic arm 4.
[0028] The grinding roller 5 is installed on one end of the telescopic arm 4. The output end of the first motor 51 is fixedly connected to the rotating shaft of the grinding roller 5 through a coupling. The first motor 51 can drive the grinding roller 5 to rotate at high speed to grind the end of the stainless steel pipe. It should be noted that the grinding roller 5 can also be replaced with a grinding disc 52, which can be used to grind the end face of the stainless steel pipe end. The grinding roller 5 can be used to grind the inner and outer walls of the stainless steel pipe end. For example, when it is necessary to grind the inner wall of the stainless steel pipe end, the center of the housing assembly 3 is first adjusted to be at the same level as the center of the stainless steel pipe by the lifting frame 2. The height is set, and then the telescopic arm 4 is extended outward by the second motor 7. The positioning process of the center of the housing assembly 3 and the center of the stainless steel tube can continuously adjust the position and height of the housing assembly 3 and push the base to move so that the center of the housing assembly 3 coincides with the center of the stainless steel tube. That is, the outer walls of the three sets of grinding rollers 5 are all attached to the inner wall of the stainless steel tube port. Then, the stainless steel tube is driven to rotate by the drive mechanism 8, and at the same time, the first motor 51 drives the grinding rollers 5 to rotate at high speed to grind the inner wall of the stainless steel tube port. The same principle applies to the outer wall and end face of the stainless steel tube port.
[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
