Detailed Description
Referring to fig. 1 to 3, the present utility model provides a deep hole machining tool comprising: the deep hole machining blade 1,
The deep hole machining blade 1 is fixedly connected with a blade body support piece 2 through a fastening stud 11, and a chip groove 4 is formed in the side surface of the upper end of the blade body support piece 2; and the chip groove 4 is positioned at the side surface of the cutter body support 2, the cutter handle 3 is arranged at the lower end of the cutter body support 2, and the fastening stud 11 is screwed in the upper surface of the cutter body support 2. The chip removal groove 4 is an arc groove surface, and an inner cooling groove hole 5 is arranged on the inner side of the cutter body support piece 2. The inner cooling slot 5 is communicated with the arc slot surface of the chip removal slot 4.
Working principle: through the deep hole processing blade 1 of synthetic diamond PCD material, make cutter body support piece 2 length enough support deep hole broken hole through shorter chip groove 4, be convenient for solve the cutter back-off problem, the product shakes the sword, the size phenomenon of exceeding is smooth, the roughness satisfies the product requirement to realized stable production, machining efficiency is higher, reduces the tool changing cycle, improves equipment comprehensive utilization rate, reduces the product debugging save time of being convenient for.
In this embodiment, the deep hole machining blade 1 is artificial diamond PCD.
As a preferred implementation mode, the deep hole machining blade 1 made of the artificial diamond PCD material has sharp cutters, the cutting resistance is small, the service life of each cutter can be ensured to be more than 1.5 ten thousand, the service life of each cutter is about 7 times that of the traditional cutter, the production stability is ensured, and the comprehensive utilization rate of equipment is greatly improved.
In this embodiment, the tool shank 3 is a special shank for a drilling machine; and the inner side of the cutter handle part 3 is fit with the cutter bar of the drilling machine.
As a preferred implementation mode, the tool handle 3 and the drill arbor are in fit installation, so that the tool is convenient to install, the matching precision is high, and the installation time is saved. The length of the chip groove 4 on the arc groove surface is shorter, so that the supporting length of the cutter body supporting piece 2 is increased, and the cutter body supporting piece 2 is more stable to support the cutter to perform deep hole breaking. The inner cooling slotted holes 5 are convenient for cooling, lubricating and chip removing, and make up for the fact that the outer cooling liquid is not sprayed in place.
In this embodiment, the tool body support 2, the tool shank 3 and the junk slots 4 constitute a support structure for a deep hole machining tool.
