In figure:
Pedestal 1, catch 2, back-up block 3, axis 4, plug plays bolt 5, spring 6, top cover 7.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in detail.Following examples will contribute to those skilled in the art and understand the present invention further, but not limit the present invention in any form.It should be pointed out that to those skilled in the art, without departing from the inventive concept of the premise, some distortion and improvement can also be made.These all belong to protection scope of the present invention.
As shown in Figure 1,2,3, 4, the present embodiment provides a kind of expansion type hole heart detent mechanism of the location for cylindric sheet metal part, comprise: pedestal 1, catch 2, back-up block 3, axis 4, plug beat bolt 5, spring 6 and top cover 7, wherein: catch 2 to be covered on pedestal 1 and fixed by securing member with pedestal 1; Pedestal 1 is provided with chute, this chute end is provided with limit features (if there are other limit methods, limit features on chute can save), catch 2 forms I shape chute (if having special operation condition requirement also can adopt the chute of other shapes) with the chute on pedestal 1; Back-up block 3 is arranged in I shape chute; The bottom of back-up block 3 is provided with the slide block agreed with mutually with pedestal 1, and the both sides of this slide block are provided with groove and agree with mutually with above-mentioned I shape chute; The inner side of back-up block 3 is provided with flare slide block and there is groove both sides; Axis 4 arranged outside have with back-up block 3 inside the tilting I shape chute (or chute of other shapes) that agrees with mutually of flare slide block; The center of pedestal 1 and axis 4 is provided with hole and plays by filling in the dead in line that bolt 5 or other axial workpieces make both pedestal 1 and axis 2; Axis 4 is provided with spring 6 (or other elasticity of substitution elements), the other end of spring 6 contacts with top cover 7, and remains compressive state; The center of top cover 7 is provided with counter sink and is fixed on by securing member the polished rod end that bolt 5 played by plug.
As one preferred embodiment, the chute quantity on described pedestal 1 looks operating mode setting, and concrete: larger by the aperture of locating hole, hole wall rigidity is poorer, the chute quantity of setting is more; Aperture is less, hole wall rigidity is better, and the chute quantity of setting is fewer.
As one preferred embodiment, the quantity of described back-up block 3 is identical with the chute quantity on pedestal 1.
As one preferred embodiment, the flare slider tilt angle inside described back-up block 3 looks operating mode setting, concrete: to need that the rigidity of mechanism is larger, accommodation is less, then flare slide block and less by the angle of the axis of locating hole; Need that the rigidity of mechanism is less, accommodation is larger, then flare slide block is with larger by the angle of the axis of locating hole.
As one preferred embodiment, the quantity of the tilting I shape chute outside described axis 4 is identical with the quantity of back-up block 3.
