Abstract
The utility model discloses a boring bar for machining a tappet pore of a motor. The boring bar for machining the tappet pore of the motor comprises a cutter body and cutting blades, wherein cutting grooves are evenly distributed at the front end of the cutter body, each cutting blade is installed in each cutting groove in a matched and sleeved mode, a radial fine-tuning structure is designed at the rear end of each cutter head, and guiding bars which are used as supports are evenly distributed on the periphery of the front end of the cutter body. Due to the fact that the machine-clip type replaceable cutting blades are applied to the boring bar for the machining the tappet port of the motor, the cutting blades are replaced directly after being damaged and cost of a cutting tool can be saved. Due to the fact that the flow amount of cooling liquid is increased and distributing positions are added to the boring bar for machining the tappet pore of the motor, the service life of a cutter tip can be effectively prolonged, and the quality and the production rate of the machining surface can be improved. Due to the fact that the fine-tuning structure is designed at the rear end of each cutting blade, machining shock patterns can be effectively reduced and avoided by means of adjustment of a back taper of a cutting edge of each cutting blade and an effective supporting function of the guiding bars on each cutting edge.
Description
Technical field
The utility model relates to the cutter auxiliary in the field of machining, is specifically related to a kind of boring cutter bar for processing engine tappet hole.
Background technology
The existing boring cutter bar that is used for processing engine tappet hole, its insert design form are welding, processing shake line occurs through regular meeting in the process, and the service life of cutter is instability also, and reconditioning trouble and cycle are long.
The utility model content
The purpose of this utility model is the problem and shortage that exists at the existing boring cutter bar blade that is used for processing engine tappet hole, and a kind of boring cutter bar for processing engine tappet hole is provided.
Technical scheme: a kind of boring cutter bar for processing engine tappet hole, comprise cutter hub and blade, the uniform cutter groove that is provided with of the front end of cutter hub, each blade coupling is set in the cutter groove, each cutter head rear end design has radially fine tuning structure, and end periphery is evenly equipped with gib block as support before cutter hub simultaneously.
Described fine tuning structure is to be provided with the fine setting hole in cutter groove one side, and the adjusting pin of wedge shape is installed in the fine setting hole, regulates the pin rear end and is provided with the adjusting jackscrew.
Blade one side is provided with apopore, and the center of apopore is over against point of a knife.
The beneficial effects of the utility model: 1. adopt the clip type detachable blade, change blade behind the blade abrasion and get final product, save the cost of charp tool.
2. increase coolant rate and distributing position, effectively improve point of a knife service life, improve machined surface quality and productivity ratio.
3. the blade rear end design has fine tuning structure, by adjusting blade cut sword back taper and gib block to effective supporting role of cutting edge, can effectively reduce and avoid processing shake line.
