[0028] Please refer to Figures 1-5 .

[0029] This utility model provides a technical solution for a water-cooled wall tube end grinding device: A water-cooled wall tube end grinding device is used to grind the inner and outer walls of water-cooled wall tubes. It includes a processing table 1 consisting of a base 101, a support plate 102, a motor 103, and a rotating shaft 104 located on one side of the output end of the motor 103. The support plate 102 is fixedly mounted on the base 101, and the motor 103 is fixedly mounted on one side of the support plate 102. The rotating shaft 104 is fixedly connected to the output end of the motor 103. This is prior art and will not be described in detail here. It also includes: a clamping assembly 2, located on the support plate 102, for clamping and supporting the water-cooled wall tube to maintain a horizontal position; a grinding assembly 3, located at one end of the base 101, for simultaneously grinding the inner and outer walls of the water-cooled wall tube in conjunction with the clamping assembly 2; and a linkage assembly 4, located between the base 101 and the support plate 102, for moving the grinding assembly 3 via the rotating shaft 104.

[0030] By setting up a base platform 101, a support plate 102, a motor 103, a rotating shaft 104, a clamping assembly 2, a grinding assembly 3, and a linkage assembly 4, the water-cooled wall tube to be ground is stably clamped on the support plate 102 by the clamping assembly 2. Then, the motor 103 and the rotating shaft 104 drive the clamping assembly 2 and the water-cooled wall tube to rotate. The linkage assembly 4 drives the grinding assembly 3 to slowly move to one end of the water-cooled wall tube, thereby achieving the effect of grinding the inner and outer walls of the water-cooled wall tube simultaneously. By controlling the start and stop of the motor 103, the grinding length can also be effectively controlled, effectively improving the grinding efficiency.

[0031] In one embodiment, the clamping assembly 2 includes a connecting plate 201 fixedly disposed at one end of the rotating shaft 104, a fixed clamp 202 and a movable clamp 203 symmetrically disposed on one side of the connecting plate 201. The fixed clamp 202 is fixedly disposed on one side of the connecting plate 201, and the movable clamp 203 is slidably disposed on one side of the connecting plate 201. A bidirectional screw 204 is rotatably disposed inside the connecting plate 201. One end of the bidirectional screw 204 passes through the side wall of the connecting plate 201 and is fixedly disposed on a control turntable 205. One end of the movable clamp 203 is provided with a threaded hole adapted to the bidirectional screw 204. A movable groove 1021 is provided on one side of the support plate 102. A support pile 206 is slidably disposed in the movable groove 1021. The inner diameter of the support pile 206 is the same as the outer diameter of the water-cooled wall tube.

[0032] This design means that only a small portion of the sidewall of the bidirectional screw 204 has threads. This arrangement is to control the range of movement of the movable clamp 203. When grinding is required at the connection of the water-cooled wall tube, the support post 206 is moved to a suitable position, one end of the water-cooled wall tube is placed on the support post 206, and then the other end of the water-cooled wall tube is aligned with the fixing clamp 202, so that the fixing clamp 202 is inserted into the interior of the water-cooled wall tube and contacts the inner sidewall of the water-cooled wall tube. By rotating the control turntable 205, the bidirectional screw 204 is driven to rotate. 04 Rotation will cause one end of the movable clamp 203, which is adapted to it, to move towards the outer wall of the water-cooled wall tube. After the movable clamp 203 is completely in contact with the outer wall of the water-cooled wall tube, the fixed clamp 202 and the movable clamp 203 will stabilize one end of the water-cooled wall tube, while the other end is placed on the support pile 206. At this time, the motor 103 is started, and the output end of the motor 103 will drive the rotating shaft 104 to rotate, which will drive the water-cooled wall tube to rotate through the connecting plate 201, the fixed clamp 202 and the movable clamp 203.

[0033] In one embodiment, the polishing assembly 3 includes a movable wall plate 301 slidably disposed on a base 101 and polishing roller 302 and polishing roller 303 fixedly disposed on one side of the movable wall plate 301.

[0034] With this design, the diameter of the first grinding roller 302 is similar to the inner diameter of the water-cooled wall tube, and the distance between the second grinding roller 303 and the first grinding roller 302 is similar to the side wall thickness of the water-cooled wall tube. This arrangement is to ensure that the first grinding roller 302 and the second grinding roller 303 can make contact with the inner and outer walls of the water-cooled wall tube when they move toward the water-cooled wall tube, thereby grinding the inner and outer walls of the water-cooled wall tube through the first grinding roller 302 and the second grinding roller 303.

[0035] In one embodiment, the linkage component 4 includes a transmission rod 401 and a limiting rod 402 rotatably disposed between the support plate 102 and the movable wall plate 301. A transmission belt 403 is disposed between the end of the transmission rod 401 near the rotating shaft 104 and the rotating shaft 104. A through hole 1022 for the transmission belt 403 to pass through is provided on the support plate 102. A thread is provided on the outer wall of one end of the transmission rod 401. A threaded groove is provided at the bottom end of the movable wall plate 301 that matches the thread of one end of the transmission rod 401. The other ends of the transmission rod 401 and the limiting rod 402 are rotatably disposed on the extension plate of the base 101. This arrangement is to enable it to rotate better between the support plate 102 and the base 101.

[0036] With this design, when the motor 103 drives the rotating shaft 104 to rotate, the rotating shaft 104 will drive the transmission rod 401 to rotate through the transmission belt 403. Since the inner diameter of the lower end of the transmission belt 403 is much larger than the inner diameter of the upper end, the rotation speed of the transmission rod 401 is much smaller than the rotation speed of the rotating shaft 104. When the transmission rod 401 rotates, since the thread on one end of it is adapted to the lower end of the movable wall plate 301, the movable wall plate 301 will move towards the water-cooled wall tube, thereby driving the first grinding roller 302 and the second grinding roller 303 to move.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
