Description

TECHNICAL FIELD

[0001] The utility model relates to metal drilling processing technical field especially relates to a kind of guiding stable device for shaft parts deep hole drilling. BACKGROUND

[0002] In various mechanical processing industries, the processing of small deep holes, especially the processing of small holes with a length-diameter ratio greater than 10 or even 50 or more, has always been a processing difficulty. According to the traditional method, only a lengthened twist drill can be used. However, the ordinary twist drill has many problems such as incomplete cooling, rapid temperature rise, etc. With the increase of drilling depth, the drilling conditions deteriorate rapidly, and drilling cannot continue. The processing depth is limited. Moreover, the machining precision is low, the surface roughness is poor, the processing efficiency is low, the operation labor intensity is large, the quality is difficult to guarantee, and it cannot meet the relevant technical requirements. In addition, it is easy to cause "chip jamming" or breakage of the drill bit, causing greater processing difficulty and thus the need for a drilling guide stabilizing device to guide and stabilize the gun drill bit.

[0003] In the prior art, a hollow lubricating coolant outlet and a chip removal channel are often designed on the drill bit. The lubricating coolant outlet further reduces the rigidity of the drill bit, and the chip removal channel increases the amplitude of the drill bit during high-speed movement, further reducing the straightness of the deep hole drilling chip. To solve the above problems, the document with application number 201720464506.7 discloses a drill bit guide mechanism for deep hole drilling equipment and deep hole drilling equipment. It includes a base, a main frame, a main sleeve, a front sealing sleeve, a first rotating shaft, a sealing guide sleeve, a second rotating shaft, and a tightening nut. The base is fixedly connected to the table rail surface of the lathe, and the main frame is fixedly installed on the base. The main sleeve is placed inside the upper end of the main frame. The front sealing sleeve is installed inside the left end of the main sleeve. The second rotating shaft is inserted into the inside of the front sealing sleeve. The second rotating shaft also has a sealing guide sleeve installed on its left end face. One end of the drill bit passes through the through hole in the center of the second rotating shaft and the sealing guide sleeve in sequence and is in close contact with the workpiece to be processed. The first rotating shaft is installed at the right end of the main sleeve, and the inside of the first rotating shaft is installed with a tightening nut. The other end of the drill bit passes through the through hole in the center of the first rotating shaft and the tightening nut in sequence.

[0004] The above-mentioned patent has the following problems when in use: During the oil return process, the cooling oil and drill chips will enter the oil return tank together, and the metal chips will be filtered by the filter plate. However, there is no cleaning mechanism inside the oil return tank to clean the filtered metal chips on the filter plate, which requires the staff to clean the filter plate in the oil return tank regularly, which is time-consuming and labor-intensive. Moreover, when a large amount of metal chips accumulate on the filter plate, it is easy to cause blockage of the filter plate, affecting the filtering effect, and there is room for improvement.
