Refer to Figures 1 - 3, A punching device for prefabricated pipe fittings, including a mounting frame 1. The mounting frame 1 includes a mounting plate 101 with mounting holes. One end of the mounting plate 101 is installed with a dial 102. On the side of the mounting plate 101 away from the dial 102, a pipe clamping structure is installed. The pipe clamping structure includes an upper positioning frame 2 installed on the mounting plate 101. The lower side of the upper positioning frame 2 is installed with a lower positioning frame 3. By closing the upper positioning frame 2 and the lower positioning frame 3, the pipeline is clamped and fixed. An adjustable punching assembly 4 is installed on the dial 102. The adjustable punching assembly 4 includes an adjusting frame 401 hinged on the dial 102. A drilling machine 403 is installed on the adjusting frame 401. The drilling machine 403 is connected to the adjusting frame 401 through a telescopic cylinder 402. By adjusting the adjusting frame 401 to change the angle of the drilling machine 403, punching operations at different angles of the pipe fittings can be carried out.

[0022] Refer to Figure 3 , The upper positioning frame 2 includes a support plate 201 installed on the back of the mounting plate 101. Upper clamping plates 202 are installed on both sides of the support plate 201. The ends of the upper clamping plates 202 pass through the lower part of the mounting plate 101 and reach the front of the mounting plate 101. And V-shaped notch grooves are opened on the upper clamping plates 202. The prefabricated pipe fittings are fixed through the V-shaped notch grooves. The center line of the V-shaped notch grooves is in the same vertical plane as the output end of the drilling machine 403.

[0023] Refer to Figure 3 , Two connecting plates 103 are installed on the back of the mounting plate 101. The middle parts of the two connecting plates 103 are fixed to the connecting plates 103 by sequentially passing two bolts through the support plate 201 and the upper clamping plates 202 to fix their height.

[0024] Refer to Figure 3 , The lower positioning frame 3 includes a threaded rod 301 installed at the upper end of the support plate 201. A moving plate 302 is threadedly sleeved on the threaded rod 301. The lower end of the moving plate 302 is fixedly connected with two connecting columns 303. The lower ends of the two connecting columns 303 slide through the support plate 201 and are connected with a positioning plate 304. Lower clamping plates 305 are fixedly connected to both sides of the positioning plate 304 by bolts. By screwing the threaded rod 301 to drive the moving plate 302 to move up and down, pulling the connecting columns 303 drives the positioning plate 304 and the lower clamping plates 305 to move along the Z axis, adjusting the height of the lower clamping plates 305 relative to the upper clamping plates 202.

The scale on the dial 102 is observed through the positioning notch 4012 to judge the drilling angle. A locking bolt 4013 is installed on the back of the rotating plate 4011. An arc-shaped groove is formed on the dial 102. The locking bolt 4013 slides through the arc-shaped groove and is connected with a nut. By tightening the nut, the position of the locking bolt 4013 relative to the arc-shaped groove is locked, and then the position of the rotating plate 4011 is locked. The telescopic cylinder 402 is installed on the rotating plate 4011, and the drilling machine 403 is installed at the output end of the telescopic cylinder 402.

By adjusting the height of the lower positioning frame 3, using the threaded rod 301 and the moving plate 302, the lower clamping plate 305 and the upper clamping plate 202 form a suitable clamping space to clamp the prefabricated pipe fitting. Then, rotate the rotating plate 4011 of the adjustable punching assembly 4 to make it correspond to the required punching angle. Observe the positioning notch 4012 and refer to the scale on the dial 102 to ensure the accuracy of the punching angle. Lock the locking bolt 4013 to fix the position of the rotating plate 4011 and ensure the stability of the angle during the punching process. Then start the telescopic cylinder 402 to drive the drilling machine 403 to move towards the prefabricated pipe fitting at a predetermined angle. The drilling machine 403 performs a punching operation on the prefabricated pipe fitting until the processing of the required hole position is completed. After the punching is completed, turn off the telescopic cylinder 402 and retract the drilling machine 403. Loosen the locking bolt 4013 and adjust the rotating plate 4011 to the initial position. Loosen the lower positioning frame 3 and take out the prefabricated pipe fitting that has been punched. Clean the device and prepare for the next use.
