The turning fixture comprises a baseplate, wherein a substrate is rotationally connected to the baseplate through a rotary hinge pin, and the hanging bracket component is placed in the middle of the substrate; rotary pressing blocks and positioning stop blocks are arranged at the periphery of the substrate respectively; the rotary hinge pin is located in a position of the center of a circle formed by the three spherical inner holes; and a positioning hinge pin is further arranged on the substrate. The turning fixture for processing the hanging bracket component aims to guarantee the dimensional precision between holes and slide tolerance, so that the machining precision is guaranteed, and the processing efficiency is improved.
Description
Technical field
The utility model relates to a kind of anchor clamps, is specifically related to a kind of turning clamp, relates in particular to the turning clamp of spherical inner hole processing usefulness on a kind of aircraft engine hanging holder set.
Background technology
The aerial high-temperature alloy part makes its machining become a difficult problem owing to reasons such as hardness height, intensity are big, poor thermal conductivity always.Part aerial high-temperature alloy part, as aircraft engine lifting bracket assembly, with reference to a kind of aircraft engine hanging holder set shown in Figure 1, itself also have following two characteristics: the one, out-of-shape, the 2nd, assembly is provided with three places hole spherical inner hole 11,12,13, has so just more increased the difficulty of processing of hanging holder set.
For guaranteeing the machining accuracy of hanging holder set, the general machining center of high rigidity that all uses carries out the processing of ball hole, the mode that adopts little amount of feeding layering to remove surplus is processed, each assembly 30-40 consuming time hour, when wherein spherical inner hole processing generally will account for the chief engineer about 1/3rd, precision is also unstable, mainly guarantees precision by increasing the feed number of times during fine finishining, and the cutter consumption is very big.
For improving working (machining) efficiency and machining accuracy, be badly in need of seeking better processing mode.By more different processing schemes, think with turning scheme the best, and this part because having row position tolerance, existing dimension precision requirement is again shaped piece, so the key of turning scheme is exactly the design of turning clamp.
Therefore, for guaranteeing working (machining) efficiency and machining accuracy, need a suitable turning clamp badly.
The utility model content
For solving the problems of the technologies described above, the utility model proposes a kind of hanging holder set processing turning clamp, to reach the raising working (machining) efficiency, the purpose of the dimensional accuracy between assurance hole and the hole and row position tolerance.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of hanging holder set processing uses turning clamp, this hanging holder set to be provided with three spherical inner holes, and this turning clamp comprises:
Base plate is connected with substrate by rotary pin shaft on the described base plate, and described hanging holder set is placed in the substrate centre position; The position is respectively equipped with rotation briquetting and position block around the substrate;
Described rotary pin shaft is positioned at the home position place of the circle of being formed with three spherical inner holes, also is provided with a location bearing pin on the described substrate.
Preferably, also be provided with deep-slotted chip breaker on the described substrate, described base plate is provided with fixed pin shaft, and the top of described fixed pin shaft and described deep-slotted chip breaker inner edge connect.
Preferably, also be provided with balance weight on the described base plate.
Preferably, described rotation briquetting comprises three.
Preferably, described position block comprises four.
Pass through technique scheme, a kind of hanging holder set processing turning clamp disclosed in the utility model, be that substrate with place work piece is rotatably provided on the base plate, the position of rotary pin shaft is benchmark with the center of circle of the circle at spherical inner hole place, three places on the workpiece, when processing each spherical inner hole, can the processing end of workpiece be gone to the machining position place by rotary plate, fix by alignment pin, carry out turning processing then, because the workpiece rotation is to be that benchmark is rotated with the center of circle, so can guarantee dimensional accuracy and row position tolerance between hole and the hole, reach the raising working (machining) efficiency, guarantee the purpose of machining accuracy.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below.
Fig. 1 is the schematic diagram of the disclosed a kind of aircraft engine hanging holder set of prior art;
Fig. 2 is the structural representation that turning clamp is used in the disclosed a kind of hanging holder set processing of the utility model embodiment.
Fig. 3 is the work schematic diagram that turning clamp is used in the disclosed a kind of hanging holder set processing of the utility model embodiment.
Fig. 4 is the work schematic diagram that turning clamp is used in the disclosed another kind of hanging holder set processing of the utility model embodiment.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described.
The utility model provides a kind of hanging holder set processing turning clamp, shown in Fig. 2-4, these anchor clamps comprise base plate 21, are connected with substrate 23 by rotary pin shaft 22 on the base plate 21, and the position of rotary pin shaft 22 is benchmark with the center of circle of the circle that three spherical inner holes on the hanging holder set are formed.This hanging holder set 24 is placed in substrate 23 centre positions, and the position is respectively equipped with three rotation briquettings 25 and four position blocks 26 around the substrate 23.Four position blocks 26 lay respectively at the hanging holder set two ends, and every end has two, and three rotation briquettings 25 are formed leg-of-mutton stable form, make hanging holder set can be stabilized on the substrate 23.
Also be provided with a location bearing pin 29 on the substrate, when substrate rotates to the Working position place, can carry out substrate orientation by alignment pin 29, prevent that substrate from moving.
Simultaneously, also be provided with balance weight 210 on the base plate, to keep the stationarity of whole base plate.
Add man-hour, base plate is connected with lathe spindle, then workpiece is placed on the corresponding position on the substrate, by position block 26 and rotation briquetting 25 it is positioned.When processing the first place spherical inner hole 11, substrate rotation to first place's spherical inner hole is positioned at the machining position place, and by alignment pin 29 substrate is positioned, then first place's spherical inner hole is processed, as shown in Figure 3.After the completion of processing, alignment pin 29 is extracted out, again substrate rotation to second place's spherical inner hole 12 is positioned at the machining position place, by alignment pin 29 substrate is positioned equally, then second place's spherical inner hole is processed, as shown in Figure 4.In like manner, continue processing the 3rd place's spherical inner hole 13.
Because the substrate rotation is by centered by the rotary pin shaft, be benchmark and rotary pin shaft is the center of circle with the circle at spherical inner hole place, three places, so even if hanging holder set is shaped piece, when the processing spherical inner hole, still can guarantee dimensional accuracy and row position tolerance between hole and the hole exactly, guarantee machining accuracy, improved working (machining) efficiency simultaneously.
The above only is preferred embodiment of the present utility model, and in order to limit the utility model, all modifications of making within spirit of the present utility model and equal conversion all should not drop within the protection domain of the present utility model.
