Description
Technical field
The utility model is specifically related to a kind of oil pressure expansion chuck gear-hobbing clamp, belongs to engineering machinery clamp for machining technical field.
Background technology
Along with the continuous lifting of socioeconomic development and machine-building level, increasing plant equipment needs to use oil pump; Gear shaft is extremely important parts in oil pump, and the precision of gear shaft processing directly can have influence on the quality of oil pump; In the process of gear shaft processing, usually all need to carry out clamping to gear shaft, traditional gear shaft clamping method is by lower toply positioning of being arranged on upper top on sliding support and installing on a spinstand, and transmission then relies on heart carrier for bolt to clamp the diameter of axle to carry out driven rotary; But adopt above-mentioned clamping method to there is a lot of shortcomings, such as: 1, heart carrier for bolt is when carrying out clamping to gear shaft, needing the time that cost is longer, wasting time and energy; 2, adopt heart carrier for bolt when carrying out clamping to gear shaft, clamping force is difficult to control, and in process, the gear shaft be clamped in heart carrier for bolt is easy to skid, thus is easy to cause hobboing cutter to break; 3, adopt heart carrier for bolt when carrying out clamping to gear shaft, owing to there is the shortcoming of easily skidding, the profile accuracy of the gear shaft after machining is unstable, reduces product percent of pass, have impact on product quality.Due to above-mentioned a variety of causes, cause gear shaft working (machining) efficiency low, precision is unstable, is difficult to meet the problem producing needs in enormous quantities.
Summary of the invention
For the problems referred to above, it is simple that the technical problems to be solved in the utility model is to provide a kind of structure, practical, easily can complete the clamping to gear shaft, and ensure the oil pressure expansion chuck gear-hobbing clamp that makes gear shaft not easily skid in process.
Oil pressure expansion chuck gear-hobbing clamp of the present utility model, comprises rotary table, and it is lower top to be arranged on rotary table, and corresponding lower top setting is upper top; Also comprise clamp body; Run through in the middle part of described clamp body and be provided with through hole; Described clamp body is socketed in lower top outside by through hole; Three grooves are evenly distributed with outside described clamp body; Described groove arranged outside has rotary pressure plate; Described rotary pressure plate by bearing pin and groove both sides hinged; Described clamp body inside is provided with oil transportation channel; On described clamp body, corresponding rotation pressing plate lower end is provided with and holds out against piston; Describedly hold out against piston and clamp body joint is provided with sealing ring; Described hold out against piston also through oil transportation channel arrange; Described clamp body side is provided with opening; Described opening and the through setting of oil transportation channel; Described open interior has been threaded connection swell fixture.
Further, described rotary pressure plate is " T " font.
The utility model beneficial effect: a kind of structure of the present utility model is simple, practical, easily can complete the clamping to gear shaft, and ensure the oil pressure expansion chuck gear-hobbing clamp that makes gear shaft not easily skid in process; Use the utility model time, first swell fixture is back-outed from opening, then in oil transportation channel, pours into lubricant grease by opening, then again swell fixture is screwed back opening part, finally again gear shaft is placed on lower top and upper top between; The utility model operationally, by turning swell fixture, it is made to be inserted into gradually in clamp body, because oil transportation channel is an airtight space, when lubricant grease in oil pipeline is subject to the extruding of swell fixture, the pressure that lubricant grease is subject to can pass to three with the pressure of equal value and equally distributedly hold out against piston, thus makes to hold out against piston outwards movement, and puts identical pressure to good use to three equally distributed rotary pressure plates; Because rotary pressure plate and clamp body are hinged, the pressure that rotary pressure plate is subject to can pass to be arranged on lower top and upper top between gear shaft, thus achieve the clamping to gear shaft; Same, as unclamped swell fixture, lubricant grease release pressure, thus release is to the pressure holding out against piston and rotary pressure plate, and then gear shaft can be taken off like a cork; Due to the pressure uniform that rotary pressure plate of the present utility model is subject to, thus the pressure of putting to good use gear shaft is also very even, and then makes gear shaft can not offset orientation benchmark; And the utility model has clamping force greatly, can ensure gear shaft and rotary table synchronous rotary, thus ensure that the requirement of form of gear tooth tolerance grade; Simultaneously the utility model have that mounting or dismounting are convenient, time saving and energy saving, the advantage of high efficiency and high position precision, the needs of gear shaft production in enormous quantities can be met.
Accompanying drawing explanation
For ease of illustrating, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is sectional structure schematic diagram of the present utility model;
Fig. 2 is the structural representation of the utility model and gear shaft clamping.
Detailed description of the invention
Oil pressure expansion chuck gear-hobbing clamp as depicted in figs. 1 and 2, comprises rotary table 1, and is arranged on lower top 2 on rotary table 1, and upper top 3 of corresponding lower top 2 settings; Also comprise clamp body 4; Run through in the middle part of described clamp body 4 and be provided with through hole 5; Described clamp body 4 is socketed in lower top 2 outsides by through hole 5; Three grooves 6 are evenly distributed with outside described clamp body 4; Described groove 6 arranged outside has rotary pressure plate 7; Described rotary pressure plate 7 is hinged by bearing pin 8 and groove 6 both sides; Described clamp body 4 inside is provided with oil transportation channel 9; On described clamp body 4, corresponding rotation pressing plate 7 lower end is provided with and holds out against piston 10; The described piston 10 that holds out against is provided with sealing ring 11 with clamp body 4 joint; Described hold out against piston 10 also through oil transportation channel 9 arrange; Described clamp body 4 side is provided with opening 12; Described opening 12 and the through setting of oil transportation channel 9; Described opening 12 inside has been threaded connection swell fixture 13; Described rotary pressure plate 7 is " T " font.
Use the utility model time, first swell fixture is back-outed from opening, then in oil transportation channel, pours into lubricant grease by opening, then again swell fixture is screwed back opening part, finally again gear shaft is placed on lower top and upper top between; The utility model operationally, by turning swell fixture, it is made to be inserted into gradually in clamp body, because oil transportation channel is an airtight space, when lubricant grease in oil pipeline is subject to the extruding of swell fixture, the pressure that lubricant grease is subject to can pass to three with the pressure of equal value and equally distributedly hold out against piston, thus makes to hold out against piston outwards movement, and puts identical pressure to good use to three equally distributed rotary pressure plates; Because rotary pressure plate and clamp body are hinged, the pressure that rotary pressure plate is subject to can pass to be arranged on lower top and upper top between gear shaft, thus achieve the clamping to gear shaft; Same, as unclamped swell fixture, lubricant grease release pressure, thus release is to the pressure holding out against piston and rotary pressure plate, and then gear shaft can be taken off like a cork.
Embodiment recited above is only be described preferred embodiment of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that this area ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
