Description

Technical Field

[0001] This utility model relates to the field of piston processing technology, specifically to an internal hole drilling device for piston housing processing. Background Technology

[0002] Chinese patent document CN221065300U discloses a piston machining drilling fixture. The fixture includes a base, one end of which is fixed to a fixing plate, and the other end is slidably mounted on a frame. Support plates are mounted on both the fixing plate and the frame, and clamping structures are provided on the support plates. A rotating rod is rotatably mounted on the base, one end of which is connected to the support plate on the fixing plate, and the other end is connected to a gear. A rack is slidably mounted on the fixing plate, meshing with the gear. Sliding the rack can drive the support plate to rotate. A bracket is mounted on the base, and a mounting plate is slidably mounted on the bracket. A drill rod is rotatably mounted on the mounting plate. During displacement, the rack drives the gear to rotate, thereby driving the piston to rotate. This eliminates the need to remove the piston pin, change its face, and then re-fix it before drilling again.

[0003] However, in the above-mentioned scheme and existing technology, the piston housing is clamped at both ends by the clamping mechanism, and the drilling mechanism performs internal drilling on the piston housing. During the drilling process, debris will fly and fall to various parts of the machine, which is inconvenient to collect and clean, and causes inconvenience to the subsequent processing of the piston housing.

The threaded groove 13 is threadedly connected to the knob bolt 18. The side end of the moving block 11 is provided with an insertion hole 14. The side wall of the baffle plate 5 is fixedly provided with a U-shaped plate 15, which is snapped into the moving block 11. The U-shaped plate 15 is provided with a round hole 16, which is inserted into the knob bolt 18. The side wall of the baffle plate 5 is symmetrically provided with insertion posts 17, which are inserted into the insertion holes 14. The moving block 11 is fixedly provided with a U-shaped frame 29, and a positioning post 20 is movably provided on the U-shaped frame 29. One end of the positioning post 20 is provided with a pull ring, and the other end of the positioning post 20 passes through the moving block 11.

[0024] In use, select a baffle plate 5 with a shell groove 6 that matches the size of the piston housing 4, insert the insert post 17 into the insert hole 14, and at this time, the U-shaped plate 15 is engaged with the moving block 11. Then, insert the knob bolt 18 into the round hole 16 and thread it into the threaded groove 13, so that the baffle plate 5 is fixedly set on the moving block 11. After the two ends of the piston housing 4 are clamped by the clamping mechanism 3, move the slider 12 along the trapezoidal slide 9 until the side walls of the two baffle plates 5 are engaged.
