Problems solved by technology
The cutter head and the blade are easily deformed and worn due to large external force, and the geometric size of the cutter head is relatively high, and it will be scrapped and cannot be used if it is slightly worn. In this way, the combined reamer needs to be replaced frequently during the processing process, and the cost very high; in figure 1 Among them, four cutter heads are evenly divided along the direction of the cylinder. Any damage to any one of the four cutter heads can affect the processing progress, and the combined reamer needs to be replaced; because the existing cutter head can only be welded The method is fixed on the cutter body, and high temperature will be generated during the welding process, so that the cutter head cannot be pre-treated with wear-resistant coating; finally, because the existing technology is an integral structure, the cutter body may be deformed during the processing , affecting the processing progress, in the existing combined reamer, the error cannot be adjusted, so that the overall processing accuracy is not high
Due to these reasons, existing combined reamers still have defects such as low machining accuracy, low service life, and high machining cost.

The invention belongs to the technical field of machining equipment, and particularly relates to a combination reamer for machining a cylinder head oil injection pore. A reamer head and reamer blades can be detachably connected with a reamer body; in the use process of the combination reamer, the reamer head and the reamer blades can be replaced individually, and whole scrapping of equipment is avoided. Meanwhile, due to the fact that adjusting screw holes are additionally formed in a flange chasis, guide strips are arranged on the reamer body, the machining precision of the combination reamer is increased, and the number of used reamer blades is decreased. According to the combination reamer for machining the cylinder head oil injection pore, the scrapping probability of the equipment is decreased, the machining precision is increased, and the production cost is greatly reduced.
Description
technical field [0001] The invention belongs to the technical field of mechanical processing equipment, and in particular relates to a combined reamer used for processing oil spray holes of a cylinder head. Background technique [0002] Existing combination reamers for processing cylinder head fuel injection holes are as follows: figure 1 As shown, the cutter head (1A), blade (2A), cutter body and base (3A) are fixed into an integral steel structure by welding. The whole is scrapped and replaced with a new combined reamer. [0003] When the existing combination reamer is used to process the oil injection air hole of the cylinder head, there are many problems, which are mainly manifested in the following aspects. The cutter head and the blade are easily deformed and worn due to large external force, and the geometric size of the cutter head is relatively high, and it will be scrapped and cannot be used if it is slightly worn. In this way, the combined reamer needs to be rep...
