Description

Technical Field

[0001] The invention relates to the technical field of drilling, in particular to a semi-automatic drilling device for processing end holes and radial holes of a cylinder. Background Art

[0002] When the cylinder is used for connection or multi-section connection, it is necessary to process end face holes and radial holes on the end face and the radial position of the end face. For cylinders of larger sizes (diameter 1.6m-2.5mm, length 4m-12m), if you want to process end face holes or radial holes on the end face of the cylinder, you need to use a large horizontal machining center or a large horizontal car with a special tool holder for processing. Since the cylinder is large, this process requires the use of a crane to lift the cylinder to a large horizontal machining center or a large horizontal car positioning mechanism. Therefore, the processing of end face holes and radial holes of the cylinder requires the use of important factory resources such as cranes and special machine tools, and the process of transportation and positioning is relatively complicated, and the drilling efficiency is extremely low. Therefore, it is urgent to develop a drilling processing equipment for end face holes and radial holes of large cylinders. Summary of the Invention

[0003] In response to the above problems, the present invention proposes a semi-automatic drilling equipment for end surface holes and radial holes of cylinders, which is directly applied to the end surface and radial drilling of large cylinders, avoiding the handling process of the cylinders.

[0049] Assembly of drilling equipment: The cylinder support mechanism 2 is mounted on the multi-axis adjustment base 5 through the shaft sleeve 21 and the rotating drive spindle 52. The drilling template 1 is interlocked with the template positioning lock 12 and the template positioning pin 20 and is mounted on the cylinder support mechanism 2.

The multi-axis adjustable base 5 is mounted on the forks of the tractor 6 via the base 50.

[0050] In order to facilitate the working principle of the semi-automatic drilling equipment for the end surface and radial holes of the cylinder, the working process is further explained below;

[0051] 1. Determine the drilling template 1 according to the cylinder model. The drilling template 1 is installed on the cylinder support mechanism 2 through the template positioning lock 12 and the template positioning pin 20 interlocked. Manually push the template positioning pin 20 to insert it into the template positioning lock 12 to fix the drilling template 1 on the cylinder support mechanism 2.

[0052] 2. Use the tractor `6 to push the drilling template 1 and the cylinder support mechanism 2 into the cylinder, and manually adjust the three-axis linkage mechanism of the multi-axis adjustment base 5 and the Z-axis lifting mechanism 511 to align the four quadrant scale lines of the drilling template 1 with the four quadrant scale lines of the cylinder. After the quadrants are aligned, lock the three-axis linkage mechanism and press the drilling template 1 against the end face of the cylinder; manually lock the tension support 15 of the drilling template 1 and the fixed foot cup 500. The locking process ensures that the four quadrants do not deviate.

[0053] 3. After the drilling template 1 is fixed to the cylinder, all the lifting support mechanisms on the cylinder support mechanism 2 are lifted up synchronously, so that the support plate 201 in the cylinder is pressed against the inner wall of the cylinder to achieve self-centering; at this time, the display value of the load-bearing sensor 515 on the Z-axis lifting mechanism 511 is used to judge whether the end of the cylinder and the multi-axis adjustment base 5 are balanced. If not, the Z-axis lifting mechanism 511 is used to fine-tune the lifting and lowering. At the same time, it is judged again whether the positions of the 4 quadrants of the drilling template 1 and the 4 quadrants of the cylinder meet the position requirements. If not, the locking state of the three-axis linkage mechanism is unlocked, and fine-tuned until the quadrants are aligned and then locked.

[0054] 4. The end-face drilling mechanism 3, radial drilling mechanism 4, and rotary drive spindle 52 are all servo-driven and connected to an external control system. The end-face and radial holes are machined according to the program. The rotary drive spindle 52 positions the drilling template 1 according to the axial angle of the hole being drilled. The end-face pneumatic locking pin 33 and the radial pneumatic locking pin 43 respectively insert into the radial drilling sleeve 14 of the drilling template 1 from their respective directions, precisely positioning the end-face drilling motorized spindle 30 and radial drilling motorized spindle 40 for either end-face or radial drilling, ensuring the rigidity and drilling accuracy of the drilling template 1. The program can process the end-face and radial holes simultaneously or in separate steps.

[0055] 5. All the lifting support mechanisms of the cylinder support mechanism 2 are synchronously lifted and retracted to zero position, the cylinder support mechanism 2 is separated from the cylinder, the tensioning support 15 on the drilling template 1 is manually unscrewed, the fixed foot cup 500 is manually retracted, and the drilling equipment is withdrawn from the cylinder by the tractor 6.

[0056] 6. Pull the drilling equipment to the tooling storage area. If it is stored for a long time, install the inner support bracket 59 to support the cylinder support mechanism 2 to prevent the overall rigidity of the equipment from being deformed due to long-term storage.
