[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please refer to Figure 1-6 ;

[0024] A cylindrical weld grinding device includes a machine base 1 and a processing table 2 installed together. A grinding mechanism 11 is mounted on the top of the machine base 1. The grinding mechanism 11 includes a grinding motor 111, and a grinding wheel 112 is fixedly mounted on the end of the output shaft of the grinding motor 111. The processing table 2 includes two parallel and spaced-apart uprights 21. Lifting mechanisms 3 are installed on the inner sides of both ends of the two uprights 21, for a total of four lifting mechanisms 3. A support frame 22 is connected to the lifting ends of two lifting mechanisms 3 located on the same side. A transverse movement mechanism 4 is mounted on the top of both support frames 22. The top of the moving ends of the two transverse movement mechanisms 4 jointly supports a horizontally arranged support plate 5. Preferably, the four lifting mechanisms 3 and the two transverse movement mechanisms 4 can all be electrically controlled slides. Other forms of power drive structures can also be selected according to actual needs. Such power structures are widely used in existing industrial automation equipment and will not be described in detail here. During operation, the four lifting mechanisms 3 are uniformly controlled by an external control system to achieve synchronous lifting and lowering movements, thereby driving the support plate 5 to rise or fall. At the same time, the two lateral movement mechanisms 4 are also coordinated and controlled by the same control system to achieve synchronous lateral movement, thereby adjusting the position of the support plate 5 in the horizontal direction. A support base 6 is installed on the top of the support plate 5. The upper surface of the support base 6 has a semi-circular recessed structure corresponding to the shape of the cylindrical body 7 to be processed, which is used to support the cylindrical body 7.

[0025] Working principle: The cylindrical body 7 to be processed is placed on the support base 6, and its position is manually adjusted so that the weld is at the lowest point and in contact with the top surface of the support base 6. Then, the four lifting mechanisms 3 rise synchronously so that the weld of the cylindrical body 7 is aligned with the lowest end of the grinding wheel 112. Next, the two transverse moving mechanisms 4 drive the support plate 5 to move towards the grinding mechanism 11, so that the grinding wheel grinds the weld while moving forward inside the cylindrical body 7. After grinding is completed, the lifting mechanism 3 lowers slightly, and the transverse moving mechanism 4 drives the support plate 5 out of the grinding area. At this time, the cylindrical body 7 that has been ground can be taken out. The whole process is highly automated and improves the efficiency of grinding the weld of the cylindrical body 7.

[0026] In another embodiment, the support base 6 is provided with a clamping mechanism 1 8 and a clamping mechanism 2 9 at its two ends. The clamping mechanism 1 8 is located at the end closer to the grinding mechanism 11, and the clamping mechanism 2 9 is located at the end farther away from the grinding mechanism 11. Through the synergistic action of the clamping mechanism 1 8 and the clamping mechanism 2 9, the cylindrical body 7 to be processed can be clamped and pressed onto the support base 6, preventing the weld position from shifting due to the movement or rotation of the cylindrical body 7 during the grinding process, thereby ensuring the grinding quality.

[0027] Two sets of clamping mechanisms 8 are provided, symmetrically arranged to form a balanced clamping force. Each set of clamping mechanisms 8 includes a limiting block 81 installed at one end of the support base 6. When placing the cylindrical body 7 to be processed, one end of the limiting block 81 is pressed against the limiting block 81, making the end face of the cylindrical body 7 flush with the end face of the support base 6. This prevents the cylindrical body 7 from extending beyond the support base 6, thus avoiding vibration or deformation during grinding due to suspension, which would affect grinding accuracy and surface quality. The top of the limiting block 81 has a crossbeam 82 extending into the cylindrical body 7. A bolt 83 is threaded onto the crossbeam 82, and a pressure sleeve 84 is threaded onto the bottom of the bolt 83. The bottom of the pressure sleeve 84 is hemispherical, which better conforms to the curved surface of the inner wall of the cylindrical body 7, improving clamping stability. A knob 85 is provided on its top for the operator to manually rotate the bolt 83. By rotating knob 85, bolt 83 can be driven to move pressure sleeve 84 up and down. When knob 85 is rotated clockwise, bolt 83 moves down, causing pressure sleeve 84 to press down on the inner wall of cylindrical body 7, applying downward clamping force from inside cylindrical body 7. At the same time, support seat 6 located below cylindrical body 7 provides upward support from the outside, supporting the outer wall of cylindrical body 7. Pressure sleeve 84 and support seat 6 work together to clamp the cylindrical body 7 to be processed, preventing displacement, shaking or rotation of cylindrical body 7 during grinding, ensuring accurate weld position and guaranteeing grinding quality. After the cylindrical body 7 is ground, rotating knob 85 counterclockwise moves bolt 83 up, and pressure sleeve 84 is lifted to release cylindrical body 7 for easy loading and unloading.

[0028] The second clamping mechanism 9 is also provided in two sets, and the two sets of clamping mechanisms 9 are symmetrically arranged. Both sets of clamping mechanisms 9 include an outward protrusion 91 integrally formed with the support base 6. The outward protrusion 91 extends towards the first clamping mechanism 8. The outward protrusion 91 and the support base 6 are provided with a cross-shaped sliding groove 92. One end of the sliding groove 92 is a closed structure, and the other end of the sliding groove 92 is an open structure. A cross-shaped slider 93 is slidably fitted in the sliding groove 92. A baffle 94 is fixedly installed at the open end of the sliding groove 92 to limit the stroke of the slider 93 and prevent it from falling out. The top of the slider 93 is provided with a limiting block 2 95, and the top of the limiting block 2 95 is provided with a crossbeam 2 96 extending into the cylindrical body 7. The crossbeam 2 96 is threaded with a bolt 2 97, and the bottom of the bolt 2 97 is threaded with a pressure sleeve 2 98. The bottom of the pressure sleeve 2 98 is hemispherical, and the top of it is provided with a knob 2 99. The bottom of the slider 93 is threaded with a clamping bolt 100. One end of the clamping bolt 100 extends to the outside of the protrusion 91, and the end of this end is provided with a knob 3 101. The diameter of the knob 3 101 is larger than the width of the bottom of the groove 92, and its bottom surface can abut against the bottom surface of the protrusion 91 to lock the slider 93. During operation, after the cylindrical body 7 to be processed is placed in position, the operator pushes the slider 93 along the slide groove 92, causing the limiting block 2 95 to move to the other end of the cylindrical body 7. When the limiting block 2 95 abuts against the end face of the other end of the cylindrical body 7, the knob 3 101 is tightened, using its bottom surface to press against the outward protrusion 91, thus locking the slider 93. At this point, both ends of the cylindrical body 7 are fixed by the limiting block 1 81 and the limiting block 2 95 respectively, completing the front-to-back limiting. Next, the knob 2 99 is rotated, driving the bolt 2 97 to move downward, causing the pressure sleeve 2 98 to move downward, applying a downward clamping force from inside the cylindrical body 7. During grinding, the support seat 6 located below the cylindrical body 7 provides upward support from the outside, supporting the outer wall of the cylindrical body 7. The pressure sleeve 2 98 and the support seat 6 work together to clamp the cylindrical body 7 to be processed, preventing the cylindrical body 7 from shifting, shaking or rotating during grinding, ensuring the accurate position of the weld and guaranteeing the grinding quality. After grinding, rotate the knob 2 99 in the opposite direction to make the bolt 2 97 and the pressure sleeve 2 98 rise and disengage from the inner wall of the cylindrical body 7. Then rotate the knob 3 101 in the opposite direction to release the locking of the slider 93, pull the slider 93 outward along the slide groove 92, release the clamping and pressing of the cylindrical body 7, and facilitate quick loading and unloading of workpieces.

[0029] It should be noted that the bottoms of knob 3 101, pressure sleeve 1 84, and pressure sleeve 2 98 are all covered with anti-slip pads. The anti-slip pads increase the friction between knob 3 101 and the bottom surface of the protrusion 91, ensuring the stability of the locking. At the same time, the anti-slip pads enhance the friction between pressure sleeve 1 84 and pressure sleeve 2 98 and the inner wall of the cylindrical body 7, preventing clamping failure or workpiece damage due to slippage during the clamping process, and improving the reliability of clamping and the stability of the grinding process.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.

This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.
