Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0014] see figure 1 and figure 2 , the drill bit 1 is connected to the cutter bar 3, and a boring tool 2 is installed at the radial position of the drill bit 1, and the boring tool 2 passes through the shaft center line of the drill bit 1, and the cutter bar 3 is provided with a circulating cooling mechanism .

[0015] The circulation cooling mechanism includes a coolant inlet hole 7 and a cutter bar inner chamber 8 communicating therewith. The coolant inlet hole 7 is arranged in the axial direction of the cutter holder 3 and is perpendicular to the cutter holder inner chamber 8 .

[0016] The drill bit 1 and the cutter bar 3 are welded as one.

[0017] The boring tool 2 is installed on the drill bit 1 through a mounting hole.

[0018] The drill bit 1 of the present invention is used to drill out the rough-machined deep hole par...

Abstract

The invention discloses a drilling and boring integrated deep hole machining device. The drilling and boring integrated deep hole machining device is characterized in that the drilling and boring integrated deep hole machining device comprises a drill bit, the drill bit is connected with a cutter bar, a boring cutter is arranged in the radial position of the drill bit, and a circulating cooling mechanism is arranged on the cutter bar. The drill bit at the front portion of the deep hole machining device conducts drilling, the boring cutter behind the drill bit conducts boring, therefore, combined type drilling and boring integrated machining is conducted on a horizontal lathe, rough machining and finish machining are simultaneously conducted, and machining is completed at a time without clamping and correcting. When the drill bit conducts deep hole drilling, the boring cutter behind the drill bit conducts boring at the same time, a clearance is formed between the drill bit and a workpiece, cutting liquid is filled into the clearance and used for conducting cooling, and the service life of the drill bit and the service life of the boring cutter are prolonged. Meanwhile, when the boring cutter conducts cutting, a center hole is naturally formed in the workpiece through the drill bit in front of the boring cutter and the drill bit is positioned, therefore, vibration caused by an overlong cantilever of the boring cutter is prevented, and the machining straightness and the size accuracy can be ensured.

Description

technical field [0001] The invention relates to the field of drilling and boring deep hole processing, in particular to an integrated drilling and boring deep hole processing device. Background technique [0002] In the process of processing various roller tables and other products of continuous casting machines, the inner holes of such workpieces belong to deep hole processing, and the length-to-diameter ratio exceeds 1:10. The traditional process in the machining industry is to drill holes on the solid round steel first, and then carry out the original method of secondary boring on the boring machine to expand and bore the large inner hole, for example, boring the central part of the solid round steel of φ280 to φ120 , The process is to drill small holes with ordinary drill bits first, and then bore out φ120 with higher precision step by step. The disadvantage of the traditional processing technology is that the drilling process cannot be cooled by cutting fluid, the d...
