[0016] 1. By setting a fixing part, a workbench and a driving mechanism, when it is necessary to drill and tap the door and window handles, the door and window handles are fixed on the fixing part, and then the driving mechanism is turned on to drive the door and window handles to rotate intermittently. When the door and window handles rotate to just below the drilling part, the drilling head is driven downward to drill the door and window handles, and then the door and window handles rotate to just below the tapping part, and the tapping part taps the door and window handles downward, and then the processed door and window handles can be removed, thereby completing the drilling and tapping process of the door and window handles; in the process of the drive mechanism driving the workbench to rotate intermittently, the drilling and tapping operations of the door and window handles are completed in sequence, and the drilling and tapping operations are combined together. Workers remove the processed door and window handles and put in the door and window handles to be processed during the intervals of the workbench rotation, and perform assembly line processing on the door and window handles, thereby greatly improving the processing efficiency of the door and window handles.

[0017] 2. By setting a rotating disc, a pushing disc and a pushing rod, when the door and window handles need to be processed, turn on the reduction motor to drive the pushing disc to rotate. When the pushing disc rotates until the pushing rod engages with the second rotating groove, the pushing rod pushes the rotating disc to rotate 90° along the second rotating groove. Then the pushing rod separates from the second rotating groove, and the outer wall of the pushing disc fits into the first rotating groove, thereby realizing 90° intermittent rotation of the workbench, so that the door and window handles can be rotated to the bottom of the drilling head and the tapping head in turn, and the drilling head and the tapping head drill and tap the door and window handles while the workbench is stopped, thereby achieving the purpose of improving processing efficiency.

[0018] 3. By setting a positioning cam, a clamping disk and a driving block, etc., during the 90° intermittent rotation of the workbench, the rotating block is driven to move along the limit groove. When the door and window handle moves to the bottom of the drilling head or the tapping head, the rotating block moves to abut against the outer wall of the first positioning part, and a clamping interval is formed between the two clamping blocks, thereby clamping the door and window handle between the two clamping blocks. After the door and window handle leaves the tapping part, the rotating block moves from the first positioning part to abut against the second positioning part, driving the moving rod close to the clamping block, so that the two clamping blocks are opened, and the processed door and window handle can be removed and the door and window handle to be processed is placed. The door and window handle is automatically clamped during the rotation of the workbench, and the worker does not need to operate manually, thereby achieving the purpose of improving processing efficiency.

A driving block 13 is provided at the end of the clamping block 6b, and a long first driving hole 14 is opened on the driving block 13. A moving block 15 is slidingly provided on the fixed block 6a, and a moving rod 16 is vertically provided on the moving block 15. The moving rod 16 can move through the two first driving holes 14. The moving rod 16 can drive the two clamping blocks 6b to approach or move away from each other. When the fixing member 6 is located directly below the drilling head 2 or the tapping head 3, a clamping gap is formed between the two clamping blocks 6b.

[0028] Furthermore, a clamping plate 17 and a positioning cam 18 are horizontally arranged on the fixed shaft 4 in sequence, and a rotating block 19 is vertically arranged at one end of the movable block 15 close to the positioning cam 18.

[0033] Furthermore, an elastic clamping layer 23 is provided on a side of the clamping block 6 b close to the moving rod 16 .

[0034] Furthermore, the outer wall of the rotating block 19 is provided with a wear-resistant layer 24 .

[0035] When it is necessary to drill and tap the door and window handles, fix the door and window handles on the fixing part 6, first place the door and window handles between the two clamping blocks 6b, then turn on the reduction motor 9, drive the pushing disc 10 to rotate, when the pushing disc 10 rotates until the pushing rod 12 is engaged with the second rotating groove 8, the pushing rod 12 pushes the rotating disc 7a to rotate 90° along the second rotating groove 8, and then the pushing rod 12 is separated from the second rotating groove 8, and the outer wall of the pushing disc 10 is fitted into the first rotating groove 7b, thereby realizing the 90° intermittent rotation of the workbench 5. During the 90° intermittent rotation of the workbench 5, when the door and window handles rotate to the bottom of the drilling part, the rotating block 19 contacts the outer wall of the first positioning portion 18a, and a clamping interval is formed between the two clamping blocks 6b, clamping the door and window handles, driving the drilling head 2 downward to drill the door and window handles, and then the door and window handles rotate to Directly below the tapping piece, the rotating block 19 is still in contact with the outer wall of the first positioning portion 18a, and the tapping piece taps the door and window handle downwards. Then the workbench 5 drives the processed door and window handle to leave the tapping piece, and the rotating block 19 moves from the first positioning portion 18a to the second positioning portion 18b, so that the two clamping blocks 6b are opened, and the worker can directly remove the processed door and window handle, thereby completing the drilling and tapping process of the door and window handle; in the process of the push rod 12 driving the workbench to rotate 590° intermittently, the automatic clamping, drilling, tapping and automatic opening of the clamping block 6b of the door and window handle are completed in sequence, combining the drilling and tapping operations together, and the worker removes the processed door and window handle and puts in the door and window handle to be processed during the interval of the rotation of the workbench 5, and performs assembly line processing on the door and window handle, thereby greatly improving the processing efficiency of the door and window handle.

[0037] By setting a positioning cam 18, a clamping plate 17 and a driving block 13, etc., during the intermittent rotation of the workbench 590°, the rotating block 19 is driven to move along the limit groove 20. When the door and window handle moves to directly below the drilling head 2 or the tapping head 3, the rotating block 19 moves to abut against the outer wall of the first positioning part 18a, and a clamping interval is formed between the two clamping blocks 6b, thereby clamping the door and window handle between the two clamping blocks 6b. After the door and window handle leaves the tapping part, the rotating block 19 moves from the first positioning part 18a to abut against the second positioning part 18b, driving the moving rod 16 close to the clamping block 6b, so that the two clamping blocks 6b are opened, and the processed door and window handle can be removed and the door and window handle to be processed is placed.
