Abstract
The utility model relates to a cartridge receiver processing fixture capable of quickly and accurately positioning and radially expanding. One end of a mandrel is connected with a transmission device; a sleeve is connected in the center of the mandrel in a sleeving way; a central bolt is connected to the upper end of the mandrel in a sleeving way through a washer; the lower end of the mandrel is arranged on a connecting base plate; the connecting base plate is arranged on a base; the central bolt is connected with a fan-shaped support plate; the fan-shaped support plate is connected with a spring, a cylindrical support block and a six-sided pyramid through a cylindrical pin, a nut, a screw rod and a washer A. According to the cartridge receiver processing fixture capable of quickly and accurately positioning and radially expanding, a workpiece can be accurately positioned, and a pressing plate can be quickly expanded and shrunk through the force transfer of the six-sided pyramid and the shrinkage of a tension spring.
Description
[technical field]
The utility model relates to a kind of fixture, is specifically related to a kind of application and aero-engine casing precision machined accurately location radially the casing clamp for machining of tensioner fast.
[background technology]
The casing processing of aero-engine, need to be used fixture precision positioning processing.Prior art is that 12 pressing plates are adjusted and compressed separately, palpus layering, single operation, and the accurate location that cannot realize inner chamber, relies on the mode of beating table centering to locate, and only plays the effect of tensioner, inefficiency.
[utility model content]
In order to overcome the deficiency of existing technology, the utility model provides a kind of accurately location radially the casing clamp for machining of tensioner fast, a plurality of pressing plates are adjusted and are compressed separately, be modified into once-through operation and adjust the accurate location that a plurality of pressing plates are realized inner chamber simultaneously, and play the effect of tensioner, realize precision positioning and increase work efficiency simultaneously.
Technical scheme that the utility model adopts is: accurately locate also fast the radially casing clamp for machining of tensioner, its axle one end connection for transmission device, axle middle part socket one sleeve, axle upper end socket centre bolt, and connect by packing ring, axle lower end is installed on connecting bottom board, and connecting bottom board is installed on base, centre bolt connects fan-shaped support plate, and fan-shaped support plate is by straight pin, nut, screw rod and packing ring A linking springs, cylinder back-up block and hexagonal pyramid.
As preferentially, described accurately location radially the casing clamp for machining of tensioner fast, its fan-shaped support plate, spring, cylinder back-up block and hexagonal pyramid have six covers, and fan-shaped support plate has 12.
The operation principle of this device, fixture is tightened with the inclined-plane change direction of displacement of hexagonal pyramid and is realized radially tensioner by centre bolt, by the contraction realization of centre bolt counter-tightened and spring, unclamps; In the time of fixture tensioner, tighten centre bolt, centre bolt passes to hexagonal pyramid by axial displacement and is converted into radial displacement, the synchronous fan-shaped support plate that promotes upper and lower two-stage, and the strain by cylinder back-up block realizes automatic fine displacement and regulates, make the fan-shaped support plate interior profile of tensioner part simultaneously, realize supporting role; When fixture unclamps, counter-tightened centre bolt, moves to fixture center under the contraction of each fan-shaped support plate, unclamps and tensioner radially.
The utility model beneficial effect: this device shrinks by hexagonal pyramid power transmission, extension spring, the accurate location of realizing workpiece, fast tensioner and contraction pressing plate.
For making further to understand feature of the present utility model and technology contents, refer to the utility model drawings and embodiments, yet appended graphic only for reference and explanation use is limited to the utility model.
[accompanying drawing explanation]
Fig. 1 is the utility model structure chart;
Fig. 2 is the utility model A-A cutaway view;
In figure, 1-straight pin; 2-nut; 3-screw rod; 4-packing ring A; 5-centre bolt; 6-packing ring; 7-sleeve; 8-connecting bottom board; 9-axle; 101 fan-shaped support plates; 102-spring; 103-cylinder gripper shoe; 104-hexagonal pyramid; 105-base.
[specific embodiment]
Below in conjunction with drawings and Examples, the utility model is described further:
As Fig. 1, accurately location radially the casing clamp for machining of tensioner fast shown in 2, its axle (9) one end connection for transmission device, axle (9) middle part socket one sleeve (7), axle (9) upper end socket centre bolt (5), and connect by packing ring (6), axle (9) lower end is installed on connecting bottom board (8), connecting bottom board (8) is installed on base (105), centre bolt (5) connects fan-shaped support plate (101), fan-shaped support plate (102) is by straight pin (1), nut (2), screw rod (3) and packing ring A (4) linking springs (101), cylinder back-up block (103) and hexagonal pyramid (104).
Fixture is tightened with the inclined-plane change direction of displacement of hexagonal pyramid and is realized radially tensioner by centre bolt, by the contraction realization of centre bolt counter-tightened and spring, unclamps; In the time of fixture tensioner, tighten centre bolt, centre bolt passes to hexagonal pyramid by axial displacement and is converted into radial displacement, the synchronous fan-shaped support plate that promotes upper and lower two-stage, and the strain by cylinder back-up block realizes automatic fine displacement and regulates, make the fan-shaped support plate interior profile of tensioner part simultaneously, realize supporting role; When fixture unclamps, counter-tightened centre bolt, moves to fixture center under the contraction of each fan-shaped support plate, unclamps and tensioner radially.
This device shrinks by hexagonal pyramid power transmission, extension spring, realizes the accurate location of workpiece, fast tensioner and contraction pressing plate.
Yet the better feasible embodiment of above-mentioned only the utility model, non-so limitation the utility model protection domain, does various distortion or applies mechanically all within this technical scheme protection domain according to above-described embodiment.
