Detailed Description
As shown in fig. 1 to 4, the automatic boring device for a camshaft hole of a diesel engine body of the present invention includes a frame 1, a working platform 2, the working platform 2 is connected to a mobile power source 7 (a displacement motor) through a transmission assembly 8 (a screw rod assembly), the working platform 2 is provided with a plurality of spindle holders 3 (one each of the front part, the middle part and the rear part), the working platform 2 is provided with a pressing plate assembly 10 (for pressing the diesel engine body 4 to be processed up and down) and a push rod assembly 9 (for laterally pushing the diesel engine body 4 to be processed) at the side edge of the spindle holder 3, the spindle holder 3 has a spindle hole 12 and a spindle 16 is sleeved in the spindle hole, the spindle 16 is provided with a plurality of milling cutters 17 (i.e. bits, corresponding to the camshaft hole of the diesel engine body), the spindle 16 and a spindle rotary power source 5 (having a speed reduction function), mounted on the frame 1 for the spindle motor).
As shown in fig. 1 and 2, a horizontal measuring instrument 11 (also located on the same side of the pressing plate assembly 10 or the ejector rod assembly 9) is installed on the working platform 2 and at the side of the spindle fixing seat 3, and is used for accurately measuring the installation horizontal position of the diesel engine body to be processed. As shown in fig. 3 and 4, the spindle 16 is provided with a flat key groove 18, and the inner wall of the spindle hole 12 of the spindle holder 3 is provided with a milling cutter groove 13 corresponding to a milling cutter and a flat key 15 corresponding to the flat key groove on the spindle, respectively, so as to be matched with the spindle and the milling cutter. The mobile power source 7 and the main shaft rotating power source 5 are electrically connected with the microcomputer controller 6 and are uniformly regulated and controlled by the microcomputer controller.
As shown in fig. 5, the diesel engine body 4 to be processed has cylinder bores 14 (six) at the top, camshaft bores 19 (six) at the lower part, and waterway positive blank holes 20 (six) at the side.
