Description
Technical Field
The utility model belongs to machining equips, concretely relates to interior reaming boring cutter of processing deep hole.
Background
In the machine-building industry, a deep hole refers to a cylindrical hole with a hole depth of more than 5 times the hole diameter, that is, a cylindrical hole with a length-diameter ratio of more than 5 times. The methods which can be used for processing deep holes at present are many: the traditional mechanical processing has absolute advantages, is mainly realized by drilling, expanding, boring and reaming, and has a plurality of corresponding cutters in the market, such as gun drill, BTA, double-pipe jet suction drill, DF system and SIED technology; in addition, some special machining technologies are gradually advanced into the deep hole machining technical field, such as electrolytic machining, electric spark machining, laser machining and the like, but are only limited to micro-hole machining and difficult-to-machine materials. In view of cost performance, the boring machining process has high precision and low cost, and the boring machining process is widely adopted at home and abroad to machine the preset hole.
The processing problem of holes with small ends and large middle parts is researched. When the holes on the workpiece are large and short, the tool rest mechanism can be used for realizing that the large holes in the workpiece can be processed in a radial moving mode on a lathe, and even if the special-shaped curved surfaces such as conical surfaces, spherical surfaces and the like are arranged in the large holes, the large holes can be processed in a profiling mode on a numerically controlled lathe. In particular, in recent years, the vibration damping boring bar which is successfully developed by taking measures of improving the static rigidity or the dynamic rigidity of the boring bar from the beginning of reducing vibration abroad can be used, and the deep hole with the slightly larger length-diameter ratio can be processed on a lathe under the matching of the vibration damping boring bar.
Abroad, Toshiba and Mitsubishi have a series of vibration damping tool bars (maximum aspect ratio of 6). The TSUPPR II CHIBAN vibration reduction cutter bar of Toshiba company cuts off a part of the cutter bar at two sides in parallel, and then inserts hard materials with high rigidity and strength to improve the static rigidity. The DAMPBAR, FSCLPF and STUP series boring bars of Mitsubishi company improve the dynamic rigidity of the cutter body by optimizing the geometric shape of the cutter body. Under the condition of not influencing the static rigidity of the cutter body, the weight of the cutter head is reduced by adopting computer simulation optimization design. Both of these approaches have their own limitations and the aspect ratio of the tool shaft cannot be very large. The damping boring bar with the length-diameter ratio of 8 is produced by Kennamantal company in America, and is also made of special materials to improve the static rigidity. At present, the most advanced vibration-damping boring bar manufacturers abroad, Sandvik company in Sweden, produce vibration-damping boring bars with the maximum length-diameter ratio of up to 16, and arrange a vibration damper in the boring bar to improve the dynamic stiffness of the boring bar. But the length-diameter ratio is also limited, the density of the vibration damping block cannot be too high, and the service life of the damper can also influence the long-term use of the boring bar. In addition to the radial feeding realized by the movement of the tool rest on the lathe, the single-tool and double-tool radial feeding series boring heads produced by the british china (ITS) company can machine short and large holes with complicated special-shaped curved surfaces such as cylindrical surfaces, conical surfaces, spherical surfaces and the like at the two ends, the middle part is large, the axial movement of the boring rod is changed into the radial telescopic movement of the cutting tool bit through an internal switching mechanism, but the structure of the boring rod only determines to machine the short and large holes, and the boring rod cannot machine ultra-long deep holes without guidance and vibration-proof functions.
For the processing of the ultra-long deep hole with small ends, large middle part and small and medium diameter, the research is few at home and abroad, the research on the problems is almost blank at home because the related data which can be searched and retrieved due to the technical protection at abroad, the deep hole processing research institute of the western's university of petroleum, king Shi, professor Zhulin and the like encounter the problems in the deep hole processing process of the water injection eccentric working barrel in the scientific research cooperation with the Tuoha oil field mechanical factory, the problem is researched by the university paper and the boring device published on the 23 rd page of the 7 th of the mechanical technologist at the school of the Ministry of Japan, and the center rotary type boring tool is developed and designed to well solve the processing of the step hole with the middle phi 21 multiplied by 50 mm. The boring cutter is simple in structure and easy to manufacture, the boring cutter is stretched by rotating the boring cutter to the upper end and the lower end through the push-pull rod, and the boring cutter block is pushed to rotate around the fixed taper pin forcibly, but the boring cutter has the following defects: firstly, the rotation expansion mode determines that the radial expansion amount is limited, and middle large holes with different apertures cannot be bored flexibly. Secondly, the aperture precision depends on the matching precision during tool assembly, and errors caused by the abrasion of the boring cutter block cannot be compensated. And thirdly, the inner conical surface, the spherical surface and other special-shaped curved surfaces cannot be processed. And fourthly, the front chip removal mode only enables the blind hole to be processed, and the blind hole is not affected.
"a deep hole machining method and apparatus with a small entrance and a large middle diameter change" of tommy drink and Li dawn utility model, first, a boring device with a tool bit adjusting mechanism needs to be sent into a through deep hole machining part, and then a special tool is used to stretch into a hole for manual tool adjustment, and the axial displacement of the adjusting cone is converted into the radial movement of the tool bit. The structure limitation is more obvious, the radial cutter adjustment is complicated and inconvenient, the stretching range is limited, the variation diameter ratio is very small between 1-1.2, and the blind hole and the overlong deep hole cannot be realized.
The deep hole reducing boring cutter mentioned in the Chinese patent utility model of stone flood steel, Zhang Shuhua and the like realizes the radial extension of the blade through adjusting the inclined plane mechanism matched with the core bar and the cutter holder, has simple structure, can solve certain practical problems and has a desirable part. But the arrangement of the guide strips is unreasonable, the guide effect is not obvious, the vibration-proof function is not realized, the radial telescopic mechanism is not mature, the limiting mechanism is not provided, the blind hole cannot be machined due to the mode of discharging the scraps, and the special-shaped curved surface cannot be machined in a profiling mode.
In the past, only electrolytic machining can be adopted for the ultra-long deep hole parts with small ends, large middle parts and large reaming margins at home and abroad. Electrochemical machining is a method of forming a workpiece by electrochemical corrosion of a cathode and an anode. Although the method is not limited by the hardness and the strength of the metal material, the method can be used for processing hard alloy, quenched steel, stainless steel and high-hardness and high-strength conductive materials, a cavity or a molded surface with a complex shape can be processed at one time by simple feeding movement, no cutting force and heat are generated in the processing, and no residual stress and burr are generated on the processed surface; but also has its fatal shortcoming: the processing precision is not high, the average precision is about +/-0.1 mm, the equipment cost is expensive, the process control requirement is strict, the production period is long, the cost is high, the efficiency is low, the method is not suitable for mass production and the environmental pollution is serious. Moreover, like electric spark, electrolysis, laser, electron beam, ultrasound and even the composite processing method among the electric spark, the electrolysis, the laser, the electron beam and the ultrasound in the special processing technology, the phi 1mm small hole and micro hole materials also have certain advantages in difficult processing materials.
In spite of the current development situation at home and abroad, the inner reaming cutter on the market at present in the field of machining is suitable for large and short holes and has no self-guiding and forced chip removal functions, or has small reaming allowance, cannot automatically radially stretch and ream, or cannot functionally realize curved surface machining. So far, the problem of the large-belly reaming of the super-long deep hole, which can effectively solve the problem that the special-shaped curved surfaces, such as a cylindrical surface, a conical surface, a spherical surface and the like, are arranged at the small ends, the middle and the large middle part, is not found at home and abroad.
