Description
Technical Field
The utility model relates to a deep hole machining tool, in particular to a tool for machining a deep hole chamfer on a diesel engine rack, and belongs to the technical field of tool equipment.
Background
The frame is a core part in a fixed part of the marine diesel engine, the quality of the frame directly influences the performance of the whole marine diesel engine, and the frame not only needs to have enough mechanical performance, but also has no defect of influencing the performance. As shown in figure 1, a chamfer is arranged on a deep hole A on a rack of an L32/40 diesel engine, the chamfer angle beta is 20 degrees, when the chamfer is processed, a used cutter is a combined type welding hard alloy blade chamfer cutter, the position of the chamfer is deeper, the length of the cutter is required to be longer, when the chamfer is processed on a horizontal boring machine, the cutter is serious in vibration, the technical requirement cannot be met, a gantry machine tool needs to be replaced to perform chamfer alone, the machine tool needs to be replaced after boring is finished to chamfer one end of the deep hole of the rack, then the rack is turned over to perform chamfer on the other end, clamping and positioning are required for multiple times, time and labor are wasted, the processing efficiency is low, the accumulated error in processing is large, and the processing quality of the deep hole of the rack is seriously affected.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a deep hole chamfering tool for a diesel engine frame, which has the advantages of simple structure, time and labor conservation, high processing efficiency and good processing quality.
The utility model is realized by the following technical scheme:
a deep hole chamfering tool for a diesel engine frame comprises a tool shank, a tool bar, a tool bit and a blade, wherein two ends of the tool bar are fixedly connected with one end of the tool shank and one end of the tool bit respectively, and the blade is fixed on the other end of the tool bit; two ends of one side of the cutter bar are respectively and fixedly provided with a guide strip; the blade is of a rectangular structure, a chamfer angle is arranged at the outer end of the blade, the chamfer angle alpha is matched with the chamfer angle beta of the deep hole of the diesel engine rack, and the thickness of the blade is 4-6 mm.
The object of the utility model is further achieved by the following technical measures.
According to the deep-hole chamfering tool for the diesel engine frame, the blade and the guide strip are both made of the coated hard alloy.
According to the deep-hole chamfering tool for the diesel engine rack, the middle parts of the tool bar and the tool bit are provided with the communicated cutting fluid channels along the axial direction.
The deep hole chamfering tool for the diesel engine frame is characterized in that the chamfering angle alpha is 20 degrees.
The chamfering machine tool has the advantages of simple and compact structure and low cost, can effectively eliminate the tool vibration phenomenon during chamfering, can finish machining the deep hole and the chamfer on the frame at one time by one-time clamping, saves the trouble of replacing a machine tool and the time of repeated clamping, can save six hours in the whole process, simultaneously reduces the accumulated error caused by repeated clamping and positioning, saves time and labor, has high machining efficiency and good machining quality, and can completely meet the requirements of drawings on the chamfering machining quality. The blade is of a thin sheet structure, chamfers matched with deep hole chamfers of a diesel engine rack in angle are arranged at the outer ends of the blade, machining precision of the deep hole chamfers can be improved, the guide strips at two ends of one side of the cutter bar can play a good role in guiding, and vibration of the cutter is reduced.
Advantages and features of the present invention will be illustrated and explained by the following non-restrictive description of preferred embodiments thereof, given by way of example only with reference to the accompanying drawings.
Drawings
FIG. 1 is a schematic diagram of a partial enlarged structure of a deep hole in a diesel engine frame;
fig. 2 is a schematic structural diagram of the present invention.
Detailed Description
The utility model is further illustrated by the following figures and examples.
As shown in figure 2, the utility model comprises a knife handle 1, a knife rod 2, a knife head 3 and a blade 4, wherein the right end of the knife rod 2 is fixedly connected with the knife handle 1 through a fastening screw, the left end of the knife rod 2 is in threaded connection with the right end of the knife head 3, the blade 4 is fixed on the left end of the knife head 3 through a fastening piece, and a cutting fluid channel 20 which is communicated with the middle parts of the knife rod 2 and the knife head 3 is axially arranged, so that the blade 4 can be directly cooled, and scrap iron can be discharged. The tool bit 3 adopts an independent structure, when the tool bit is damaged and needs to be replaced, the tool can be continuously used only by replacing the tool bit 3, and the whole tool does not need to be replaced. The cutter bar 2 is made of 45 steel, thermal refining is carried out to ensure that radial runout of two ends is less than or equal to 0.05mm, and guide strips 21 are fixedly arranged at two ends of the lower side of the cutter bar 2 respectively. Blade 4 is the rectangle structure, and the outer end of blade 4 is equipped with the chamfer, and chamfer angle alpha matches with the chamfer angle beta of diesel engine frame deep hole, and chamfer angle alpha is 20 in this embodiment, and the thickness of blade 4 is 4mm ~ 6mm, and the thickness of blade 4 is 5mm in this embodiment, and blade 4 and gib block 21 all adopt the carbide of taking the coating to make, have good wearability, can prolong the life of the two.
