[0028] The present utility model provides an end face grinding device for an anti-corrosion and heat-insulating steel pipe as shown in Figure 1 and includes a fixing mechanism 1, and further includes:

[0029] The clamping mechanism 2 is arranged at the inner end of the fixing mechanism 1 and is used for clamping and fixing the insulated steel pipe.

[0030] The grinding mechanism 3 is arranged at the other inner end of the fixing mechanism 1 and is used for grinding the end face of the insulated steel pipe.

[0031] For the convenient grinding operation of the insulated steel pipe, as Figure 2 and Figure 3 shown, the fixing mechanism 1 includes a fixing base plate 101. At one end of the top of the fixing base plate 101, a mounting plate 104 is fixedly installed. At the other end of the top of the fixing base plate 101 and at a position close to the mounting plate 104, placing plates 102 are fixedly installed. At the top between the mounting plate 104 and the adjacent placing plate 102, a protective cover 105 is fixedly installed. The clamping mechanism 2 inside the two placing plates 102 can clamp and fix the insulated steel pipe. The grinding mechanism 3 installed at one end of the mounting plate 104 can grind the end face of the insulated steel pipe. At the same time, the protective cover 105 can protect against the dust generated during the grinding process.

[0032] For the convenient grinding operation of the end faces of insulated steel pipes with different diameters, as Figure 2 and Figure 5 shown, the grinding mechanism 3 includes a movable toothed plate 301 and a rotating shaft 306. The movable toothed plate 301 is rotatably installed on the inner wall of one end of the mounting plate 104. At the top of the inner wall of the movable toothed plate 301, an electric push rod 303 is arranged. The output end of the electric push rod 303 is fixedly installed with a movable seat 304. A grinding plate 305 is inserted into the inner wall of the movable seat 304. The rotating shaft 306 is rotatably installed on the inner wall of one side of the mounting plate 104. At one end of the rotating shaft 306, a servo motor 307 is arranged. At the other end of the rotating shaft 306, a rotating gear 308 meshing with the movable toothed plate 301 is fixedly sleeved. When the electric push rod 303 works, it can adjust the position of the grinding plate 305 in the radial direction of the movable toothed plate 301, and thus can be conveniently adjusted according to the diameter of the insulated steel pipe. When the servo motor 307 works, through the meshing action between the rotating gear 308 and the movable toothed plate 301, the grinding plate 305 can grind different positions of the end face of the insulated steel pipe.

[0033] In order to enable the clamping mechanism 2 to conveniently clamp insulated steel pipes with different sizes, as Figures 2 - 4As shown, the inner walls of the two placement plates 102 are each provided with a placement groove 103, and telescopic parts 201 are rotatably installed on the top and bottom of both sides of the inner wall of the placement groove 103, and the two telescopic parts 201 on the same side are rotatably installed with a clamping plate 202 on the side away from the inner wall of the placement groove 103, and the outer walls of both sides of the placement plate 102 are threadedly inserted with fastening bolts 203, and the screw parts of the two fastening bolts 203 penetrate the inner wall of the placement groove 103 and are connected with the outer wall of the adjacent clamping plate 202. The placement groove 103 can install and fix the clamping mechanism 2, and the telescopic part 201 can pull and limit the clamping plate 202. Through the tightening action of the fastening bolts 203, the clamping plate 202 can stably clamp the insulated steel pipes of different sizes.

[0034] In order to conveniently clean the debris generated during the grinding process, Figure 2 and Figure 3 As shown, a slag discharge port 106 is provided on the inner wall of the fixed base plate 101 and between the mounting plate 104 and the adjacent placement plate 102. The slag discharge port 106 is provided below the protective cover 105. The debris accumulated during the grinding process can be quickly cleaned through the slag discharge port 106.

[0035] In order to keep the grinding plate 305 stable during the adjustment process, Figure 2 and Figure 5 As shown, a mounting groove 302 is provided at the top of the inner wall of the movable tooth plate 301, the top of the inner wall of the mounting groove 302 is fixedly connected to the electric push rod 303, the inner wall of the mounting groove 302 is movably connected to the outer wall of the movable seat 304, and the mounting groove 302 can limit the movement of the movable seat 304, so that the grinding plate 305 remains stable during the movement.

[0036] In order to provide power for the circular motion of the grinding plate 305, as Figure 2 As shown, the outer wall of one end of the mounting plate 104 is fixedly connected to the servo motor 307, and the servo motor 307 is connected to the rotating shaft 306 through the output shaft transmission. The mounting plate 104 can install and fix the servo motor 307. The operation of the servo motor 307 causes the rotating shaft 306 to rotate, and through the meshing action between the rotating gear 308 and the movable tooth plate 301, the grinding plate 305 can grind different positions of the end face of the insulation steel pipe.

[0037] When grinding the end face of the insulated steel pipe, the insulated steel pipe is inserted into the placement grooves 103 on the inner walls of the two placement plates 102. By rotating the four fastening bolts 203, the two clamping plates 202 on the inner wall of the same placement groove 103 can be pushed to move relatively, so that the adjacent telescopic members 201 are extended accordingly, and then the four clamping plates 202 can clamp and fix the outer wall of the insulated steel pipe, making the insulated steel pipe stable during the grinding process. Then, through the operation of the electric push rod 303, the movable seat 304 moves along the inner wall of the installation groove 302, so that most areas of the grinding plate 305 can be in full contact with the end face of the insulated steel pipe, enabling the grinding mechanism 3 to adapt to the end face grinding work of insulated steel pipes of different sizes. Then, through the operation of the servo motor 307, the rotating shaft 306 rotates, which can drive the rotating gear 308 to rotate. Through the meshing of the gear parts, the movable tooth plate 301 rotates on the inner wall of the mounting plate 104, so that the grinding plate 305 can perform grinding operations on different positions of the end face of the insulated steel pipe, improving the grinding efficiency of the end face of the insulated steel pipe. This embodiment specifically solves the problem in the prior art that it is impossible to conveniently adjust according to the diameter of the insulated steel pipe, which will affect the processing efficiency of the insulated steel pipe.

Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
