[0022] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model discloses an end grinder for processing stainless steel pipes, comprising a base plate 10, a support column 1, a crossbar 2, and a stainless steel pipe 6 to be processed. A bearing is embedded in the base plate 10. One end of the support column 1 is installed in the inner ring of the bearing, and the other end is fixedly connected to the crossbar 2. The end of the crossbar 2 facing the support column 1 has an installation port 15, in which a cylinder 3 is installed. A bracket 4 is installed on the piston rod of the cylinder 3. Both sides of the bracket 4 extend to the outside along the opening of the installation port 15 and are fitted with push rings 5. The push rings 5 ​​are sleeved on the outside of the crossbar 2. The stainless steel pipe 6 is sleeved on the crossbar 2 and abuts against the push rings 5. A grinder for grinding the end face of the stainless steel pipe 6 is installed at the end of the base plate 10 away from the support column 1.

[0023] In this embodiment, the grinding mill includes a grinding wheel 7, a protective cover 8, a motor 14, and a support frame 9. The grinding wheel 7 is disposed inside the protective cover 8, and one side of the grinding wheel 7 is in contact with the end face of the stainless steel tube 6. The motor 14 is mounted on the outer side of the protective cover 8, and the rotating shaft of the motor 14 passes through the protective cover 8 and is fixedly connected to the center hole of the grinding wheel 7. One end of the support frame 9 is mounted on the protective cover 8, and the other end is mounted on the base plate 10.

[0024] Both the motor and the cylinder are connected to a controller via wires. The controller can control the extension and retraction of the cylinder and the start and stop of the motor.

[0025] In this embodiment, a positioning seat 11 is provided on the side of the support column 1 away from the crossbar 2. A support plate is installed between the positioning seat 11 and the base plate 10. A positioning hole is provided in the center of the positioning seat 11. An insertion hole is provided on the support column 1 opposite to the positioning hole. A positioning rod 16 is provided in the positioning hole. One end of the positioning rod 16 is inserted into the slot, and the other end extends to the outside and is equipped with a handle 13.

[0026] In this embodiment, a compression spring 12 is sleeved on the exposed section of the positioning rod 16. One end of the compression spring 12 is installed on the grip rod 13, and the other end is installed on the positioning seat 11. The compression spring can squeeze the grip rod and the positioning rod, so that the positioning rod can be automatically inserted into the socket.

[0027] In this embodiment, the crossbar 2 is arranged parallel to the base plate 10, so that the end face of the crossbar can be arranged parallel to the end face of the grinding wheel.

[0028] In this embodiment, the bracket 4 is arranged in a "U" shape, and the width of the bracket 4 matches the width of the mounting port 15, so that the bracket can move stably along the axial direction of the mounting port and avoid swaying.

[0029] In this embodiment, the base plate 10, support column 1, and crossbar 2 are all made of metal materials, which increases the sturdiness and service life.

[0030] As attached Figure 4 As shown, when installing the stainless steel pipe, hold the handle and pull the positioning rod outward. After the positioning rod is pulled out of the insertion hole, the crossbar can be rotated directly, so that the crossbar rotates around the support column. After one end of the crossbar is removed from the inside of the protective cover, the stainless steel pipe can be directly fitted onto the crossbar and rotated back to the crossbar. The positioning rod is then reinserted into the insertion hole by the return of the compression spring, which can position the crossbar so that the crossbar is set opposite to the grinding wheel.

[0031] After the above is completed, start the motor and cylinder. The start of the motor drives the grinding wheel to rotate, while the cylinder pushes the bracket. The movement of the bracket drives the push ring, which pushes the stainless steel tube to move along the crossbar until it contacts the rotating grinding wheel, thus quickly completing the grinding operation on the end face.

[0032] Furthermore, after pulling the positioning rod outward again, the crossbar can rotate again around the support column. After the crossbar is moved away from the inside of the protective cover, the stainless steel tube can be directly removed from the crossbar, making it convenient for disassembly and flipping.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
