Description

Technical Field

[0001] This utility model relates to the field of grinding device technology, and in particular to a grinding device for the inside of wear-resistant cast pipe. Background Technology

[0002] Cast iron pipe (also known as cast iron pipe or cast pipe) is a type of pipe manufactured using casting technology. It is primarily made of cast iron and is widely used in water supply, drainage, heating, sewage, and industrial pipelines. Due to its good corrosion resistance, wear resistance, and high strength, cast iron pipe is widely used in many industries. During the production process, the inner wall of the cast iron pipe needs to be ground.

[0003] In the prior art, Chinese patent application number 202320511338.8 discloses a device for grinding the oxide layer on the inner wall of a cast pipe, including a device body and a support frame. A collection box is installed through the device body, with rollers at the lower end of the collection box. A handle is connected to the front of the collection box, and a hand-tightening bolt is installed through the front of the collection box. One end of the hand-tightening bolt is threaded to the device body. A cleaning bracket is installed near the left side of the upper end of the device body. This utility model uses a first hydraulic telescopic rod to push the clamping frame to clamp and fix the cast pipe. According to the inner diameter of the cast pipe, the grinding roller on the chuck is disassembled and replaced. A second motor and a bevel gear set drive the screw to rotate, causing the moving frame to move and adjust on the screw, moving the grinding roller into the cast pipe to grind its inner wall. After grinding, the grinding roller is moved out of the cast pipe. Under the action of the first motor, the limiting plate frame is rotated through the rotating shaft, thereby causing the clamped cast pipe to rotate and tilt, dumping out the waste generated during the processing of the cast pipe.

[0004] However, the above-mentioned technical solutions have the problem that the size of the grinding roller is fixed and cannot be adjusted. When it is necessary to grind the inner wall of cast pipes of different diameters, it is necessary to disassemble and replace the appropriate grinding roller. This operation is time-consuming and laborious, which greatly reduces the grinding efficiency. Therefore, this application proposes a wear-resistant cast pipe internal grinding device to solve the above problems. Utility Model Content

[0014] As a preferred embodiment of this utility model, a plurality of sliding rods are fixedly installed on the right side of the turntable, and an annular groove is provided on the left side of the moving plate, with the right end of the sliding rods slidably connected inside the annular groove.

[0015] In a preferred embodiment of this utility model, the positioning component includes a locking rod, a slip ring, and a spring. The turntable has multiple slots, and the bottom end of the locking rod engages with each slot. The slip ring is fixedly installed on the left side of the moving plate and slides on the locking rod. The spring is sleeved on the locking rod, with the top end of the spring fixedly installed on the locking rod and the bottom end of the spring fixedly installed on the top of the slip ring.

[0016] In a preferred embodiment of this utility model, the clamping mechanism includes a lifting plate, two first electric push rods, four second electric push rods, two mounting plates, two third electric push rods, and two clamping plates.

[0021] 3. By using a spring to drive the locking rod to move down and reset, the rotation of the turntable can be limited after multiple grinding rollers have been switched, through the locking and limiting between the locking rod and the corresponding locking groove, thereby improving the stability of the grinding rollers when grinding the cast pipe.

[0022] 4. By placing the cast pipe on top of the lifting plate, and then activating the second electric push rod, the mounting plate and two clamping plates can be adjusted in height to ensure that the clamping plates are horizontally aligned with both sides of the cast pipe. Then, activating the third electric push rod can clamp and fix the cast pipe with the two clamping plates. After the cast pipe is clamped and fixed, activating the first electric push rod can adjust the height of the lifting plate and the cast pipe to ensure that the right end of the cast pipe is horizontally aligned with the left end of the corresponding grinding roller, ensuring that the grinding roller is stably inserted into the interior of the cast pipe for grinding.

[0023] This invention enables the inner wall grinding of cast pipes of different diameters through a simple structure. It eliminates the need to disassemble and replace the grinding rollers. By switching between multiple grinding rollers of different diameters, the operation is time-saving and labor-saving, greatly improving grinding efficiency and making it highly practical.

Then, starting the third electric push rod 20 can make the two clamping plates 21 clamp and fix the casting pipe. After the casting pipe is clamped and fixed, starting the first electric push rod 17 can make the lifting plate 16 and the casting pipe height adjusted to make the right end of the casting pipe horizontally correspond to the left end of the corresponding grinding roller 11, ensuring that the grinding roller 11 is stably inserted into the inside of the casting pipe for grinding.

[0043] As a preferred embodiment of this utility model, two rectangular holes 22 are provided on the processing table 1, and the bottom end of the second electric push rod 18 passes through the corresponding rectangular holes 22 and extends to the bottom of the processing table 1.

Activating the second electric push rod 18 will adjust the height of the mounting plate 19 and the two clamping plates 21 to ensure the clamping plates 21 are horizontally aligned with both sides of the casting pipe. Activating the third electric push rod 20 will clamp and fix the casting pipe with the two clamping plates 21. After the casting pipe is clamped and fixed, activating the first electric push rod 17 will adjust the height of the lifting plate 16 and the casting pipe to ensure the right end of the casting pipe is horizontally aligned with the left end of the corresponding grinding roller 11. Correspondingly, to ensure that the grinding roller 11 is stably inserted into the inside of the cast pipe for grinding, after the cast pipe is fixed, the first motor 23 can drive the turntable 6 and multiple second motors 9, multiple jaws 10 and multiple grinding rollers 11 to rotate and adjust, thereby realizing the repositioning adjustment of multiple grinding rollers 11. Here, the multiple grinding rollers 11 have different diameters, so they can adapt to the grinding of the inner wall of cast pipes of different diameters, which is highly applicable. In addition, the electric slide rail 3 can drive the moving plate 2 and the grinding mechanism on it to move laterally, thereby realizing the reciprocating grinding operation of the inner wall of the cast pipe.
