Description
Technical field
The utility model relates to a kind of joint Precision Machining servicing unit, relates in particular to a kind of undercarriage jointing Precision Machining servicing unit.
Background technology
Undercarriage jointing is the strength member that connects Aircraft Main undercarriage front strut and pressurized strut, and this part has the oblique cutting auricle of two different angles, and two groups of auricles and part bottom surface out of plumb, have very large gradient.Due to the particularity of undercarriage jointing design of part, three common axle lathes cannot machine, and at present, processing undercarriage jointing part is all to be processed by the five-axis machine tool of import.
Five-axis machine tool equipment price costliness, maintenance cost is high, causes processing cost very high, the most important thing is that undercarriage jointing part material is TC18 titanium alloy, because this Tensile strength is large, toughness is large, and hardness is high, cause machining difficulty, five-axis machine tool mostly is electric main shaft, and machine torque is little, easily causes main shaft overload when processing undercarriage jointing, and bite is little, efficiency is very low.
Utility model content
The purpose of this utility model is to overcome existing five-axis machine tool equipment price costliness, and the problem that three axle lathes cannot be processed part for this reason, provides a kind of joint Precision Machining servicing unit that aids in three axle lathes.
It is as follows that the utility model solves the problems of the technologies described above taked technical scheme:
A kind of joint Precision Machining servicing unit, comprise: the base plate being connected with platen and be located at the part installing plate on base plate, wherein, described and base plate part installing plate is fixed together by gripper shoe, and described part installing plate is provided with multiple dowel holes and screwed hole, described screwed hole is connected with pressing plate by hold-down bolt, part to be processed is fixed on part installing plate by described pressing plate, and inserts alignment pin in described dowel hole.
Further, preferably, described part installing plate is a rectangular slab, and the Si Jiaochu of its rectangular slab is provided with described screwed hole.
Further, preferably, described dowel hole is positioned at the both sides of the center line of described rectangular slab.
Further, preferably, described part two ends to be processed is reserved false boss, and on false boss, drills the pin-and-hole corresponding with described dowel hole, and it is vertical that the bottom surface of pin-and-hole and part keeps, and described pressing plate compresses described false boss.
After the utility model has been taked such scheme, can strengthen the practicality of three axle lathes, alleviate the expensive expense that processing undercarriage jointing must be processed with five-axis machine tool equipment.
Other features and advantages of the utility model will be set forth in the following description, and, partly from description, become apparent, or understand by implementing the utility model.The purpose of this utility model and other advantages can be realized and be obtained by specifically noted structure in write description, claims and accompanying drawing.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is described in detail, to make above-mentioned advantage of the present utility model clearer and more definite.
Fig. 1 is the part schematic diagram of the undercarriage jointing to be processed in the utility model joint Precision Machining servicing unit;
Fig. 2 is the structural representation of the utility model joint Precision Machining servicing unit;
Fig. 3 is the use state diagram of the utility model joint Precision Machining servicing unit;
Fig. 4 is the part schematic diagram of the undercarriage jointing to be processed in the utility model joint Precision Machining servicing unit.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in detail.
As shown in Figure 1, be the undercarriage jointing part that needs processing, it comprises two groups of auricles that gradient is different, need to make independent processing unit (plant) for each auricle, only angle difference of two groups of devices, accessory, installation way, processing method are all consistent.
Be all generally to process based on five-axis machine tool at present, the present invention is based on above feature, i.e. only angle difference of two groups of devices, and accessory, installation way, processing method are all consistent.
For this reason, a kind of joint Precision Machining servicing unit is provided, process to aid on three axle lathes, for example, can be according to making independent processing unit (plant) for each auricle, then process, specifically, as shown in Figure 2, a kind of joint Precision Machining servicing unit, comprise: the base plate that is connected with platen 1 and be located at the part installing plate 3 on base plate, wherein, described and base plate part installing plate is fixed together by gripper shoe 2, and, described part installing plate is provided with multiple dowel holes and screwed hole, described screwed hole is connected with pressing plate 31 by hold-down bolt 32, part to be processed is fixed on part installing plate by described pressing plate, and in described dowel hole, insert alignment pin 33.
Wherein, as shown in Figure 3 and Figure 4, described part two ends to be processed is reserved false boss 42, and on false boss, drills the pin-and-hole corresponding with described dowel hole 41, and it is vertical that the bottom surface of pin-and-hole and part keeps, and described pressing plate compresses described false boss.
As shown in Figure 3, wherein, tiltedly auricle 4 is provided with auricle skewed slot 41, after part being installed on part installing plate, angle shape right angle in 90 ° between the angle of the oblique auricle on part and base plate and part installing plate, auricle skewed slot is kept vertically upward, so just can use three axle lathes to process skewed slot.
After the utility model has been taked such scheme, can strengthen the practicality of three axle lathes, alleviate the expensive expense that processing undercarriage jointing must be processed with five-axis machine tool equipment.
When in use, first when rough turn condition at the reserved false boss of part two ends, and drill pin-and-hole on the reserved process area in both sides, the pin-and-hole drilling will keep vertical with the bottom surface of part;
The servicing unit of processing skewed slot is installed on to the work top of three axis numerically controlled machine, after base plate and the laminating of lathe table top, smooths, look for straight with dial gauge again.Part, by inserting after alignment pin location, calibration, is fixed with pressing plate.After the complete part of clamping, check again the accuracy of confirming angle after clamping, errorless rear use three axle lathes carry out the processing of skewed slot, and other skewed slot also can similarly be processed, and does not repeat.
Finally it should be noted that: the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement.All within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
