Abstract
The utility model relates to the field of machining devices, and provides a deep hole lengthened drill extension rod. The deep hole lengthened drill extension rod is characterized by comprising a round rod (2), a Morse taper rod (1) connected with a Morse drill chuck in a Morse matching mode is arranged at one end of the round rod (2), a Morse taper hole (4) connected with a drill Morse drillstock in a Morse matching mode is arranged at the other end of the round rod (2), and a waist-shaped through hole (3) is arranged in the bottom of the Morse taper hole (4). The deep hole lengthened drill extension rod has the advantages that new devices are not added; the tool is practical, manufacturing is simple and cost is low; operation is simple and convenient; and a worker with common operation skills can complete the work. Thus, the deep hole lengthened drill extension rod can be widely used for deep hole machining in the field of machining and has wide practicability.
Description
Technical field:
The present invention relates to the apparatus field of mechanical metalworking, the deep hole that particularly uses in drilling machine equipment adds the jumping chisel extension bar.
Technical background:
Not only volume is large, Heavy Weight for some part at present, and the processing difficulties of its complicated inner cavity slotted hole is larger, and processing cost is higher, and labour intensity is larger, and the process-cycle is longer.
The deep hole machining of M type compressor components for example, with the processing of Z080 radial drilling machine:
M type compressor Main Feature is high pressure, large discharge capacity, and main zero (section) part of compressor all adopts forging, and not only volume is large for part, Heavy Weight, and the profile of part, inner chamber are also more complicated; Particularly the processing difficulties of a plurality of slotted holes of inner cavity of component is larger, usually the accepted standard drill bit also can only bore dark 225mm, add long bushing boring and also can only bore dark 365mm and can't reach the requirement of drawing hole depth and adopt, will occur the standard fluted drill when especially processing the deep hole of this large forgings, lengthen the problem that fluted drill all can't be processed, the problem of super machine tool travel processing is also particularly outstanding simultaneously.
Summary of the invention:
The object of the present invention is to provide a kind of deep hole to add the jumping chisel extension bar, the deep hole machining problem of the heavy parts that solution standard fluted drill, lengthening fluted drill all can't be processed, and the problem of super machine tool travel processing.
The objective of the invention is to be achieved by the following technical programs:
Deep hole adds the jumping chisel extension bar, it is characterized in that comprising circular pin, one end of circular pin is provided with the Mohs cone bar that is connected with the drill chuck mohs tapered bore, and the other end of circular pin is provided with the mohs tapered bore that is connected with drill bit Mohs drillstock, and the mohs tapered bore bottom is provided with the through hole of waist type.
Described Mohs cone bar is characterized in that Mohs cone bar Morse's taper is 6.
Described mohs tapered bore is characterized in that the mohs tapered bore Morse's taper is 4.
The invention has the advantages that first: do not increase new equipment; Second: instrument is practical, manufacturing is simple, cost is low; The the 3rd: simple, convenient; The the 4th: have the personnel of general operation technical ability can complete this work; This invention can be widely used in the deep hole machining of field of machining, has practicality widely.
The present invention is further described below in conjunction with drawings and Examples:
Description of drawings:
Fig. 1 is the front view that deep hole adds the jumping chisel extension bar;
Fig. 2 is the side view that deep hole adds the jumping chisel extension bar;
Fig. 3 the present invention is applied in Z080 radial drilling machine machining sketch chart.
The instantiation mode:
As shown in Figure 1 and Figure 2, the invention provides a kind of deep hole and add the jumping chisel extension bar, it is characterized in that comprising circular pin 2, one end of circular pin 2 is provided with the Mohs cone bar 1 that is connected with the drill chuck mohs tapered bore, the other end of circular pin 2 is provided with the mohs tapered bore 4 that is connected with drill bit Mohs drillstock, and mohs tapered bore 4 bottoms are provided with the through hole 3 of waist type.
The Morse's taper of above-mentioned Mohs cone bar 1 is 6.
The Morse's taper of above-mentioned mohs tapered bore 4 is 4.
As shown in Figure 3, the present invention is applied on Z080 radial drilling machine processing M type compressor, and deep hole adds jumping chisel extension bar top and drill chuck chuck 6 is connected, and bottom and fluted drill 5 are connected, and bore deeply can reach 870mm, satisfy drawing requirement.
Adopt deep hole to add the jumping chisel extension bar, but the actual grade in root a tree name hole design, make, efficiently solve the deep hole drilling problem, the present invention can be widely used in the drilling of compressor large-sized forging part deep-hole, similar deep hole machining can the method be improved, implement; When overrange processing, also can adopt the present invention to improve, implement.
