Embodiment
Advantage of the present invention is set forth further below in conjunction with accompanying drawing and specific embodiment.
As shown in Figures 1 to 4, the present invention proposes a kind of fixed form of reliable module kernel 2 and corresponding modular structure, for laser alignment instrument, the fixing module kernel 2 as generating laser, makes this kernel 2 to stablize outgoing laser beams.In a preferred embodiment of the invention, this modular structure comprises shell 1 and kernel 2, and they are column type shapes of form fit, and shell 1 is set in outside inner casing.Wherein, shell 1 has hollow cavity 11 and through hole 12, this hollow cavity 11 runs through along the bearing of trend of shell 1 and makes shell 1 be a kind of hollow-core construction, hollow cavity 11 holds kernel 2 in wherein, being inserted with fixture 3 in through hole 12, being installed to by kernel 2 in the process of shell 1, first kernel 2 being filled in hollow cavity 11, kernel 2 supported by the fixture 3 re-using such as screw and so on, and kernel 2 is tightly close together because of the pressure of fixture 3 with the inside surface 13 of shell 1.Make it circumference, radial direction or axial displacement do not occur in order to kernel 2 fixed effect be fixed in shell 1 can be strengthened, with through hole 12 along the relative position of the radial direction of shell 1, the inside surface 13 of shell 1 is provided with groove 14, this groove 14 radially protrudes outwardly, the edge of groove 14 and the inside surface 13 of shell 1 are connected to first make contact 15 and the second contact point 16, by first make contact 15, second contact point 16 and fixture 3, kernel 2 is fixed in hollow cavity 11.From cross section, the first make contact 15 of groove 14 and the second contact point 16 form a leg-of-mutton fixed sturcture with fixture 3, be different from the structure that single-point under the stressing conditions of kernel 2 when originally there is not groove 14 is fixing, leg-of-mutton fixed sturcture effectively can give kernel 2 pressure from three directions, particularly, fixture 3 gives kernel 2 power upwards (for convenience of description in radial direction, for azimuth reference immediately below modular structure of the present invention is in fixture 3 and through hole 12 temporarily), first make contact 15 gives the power of kernel 2 to bottom right in radial directions, second contact point 16 gives kernel 2 power to left down in radial directions, like this, utilize the feature of triangular structure good fixing effect, strengthen kernel 2 and be fixed on firmness in shell 1, this simple structure has very practical value.
In a preferred embodiment of the invention, groove 14 is designed to circular arc, its radius-of-curvature is less than the inside surface 13 of shell 1, this groove 14 is outputed on the inside surface 13 of shell 1 by Milling Machining technology, be mainly used in forming two center of effort in the junction of the inside surface 13 of groove 14 and shell 1---first make contact 15 and the second contact point 16, thus form triangle fixed sturcture mentioned above.
In a preferred embodiment of the invention, first make contact 15 earrings second contact point 16 is axisymmetric about the straight line at the axle place of through hole 12, namely first make contact 15 gives the angle that power that the power of kernel 2 and the second contact point 16 give kernel 2 and fixture 3 give the power of kernel 2 is equal, that is first make contact 15, second contact point 16 and through hole 12 form an isosceles triangle, with the line of first make contact 15 and the second contact point 16 for base, respectively with first make contact 15, second contact point 16 is waist with the line of fixture 3, with the pedal line through fixture 3 for axis of symmetry, the fixed sturcture of such formation isosceles triangle, further reinforcement kernel 2 is fixed on the fastness in shell 1.
In a preferred embodiment of the invention, in order to limit the displacement of kernel 2 in hollow cavity 11 further, firm module kernel 2, shell 1 is provided with perforate 17, radially run through whole shell 1, groove 14 extends to the outside surface of shell 1, by carrying out a glue operation in perforate 17, thus is fixed in hollow cavity 11 by kernel 2.The setting of perforate 17 can be convenient to a glue operation more, thus the kernel 2 that is generally fixed by mechanical force can be gone out at groove 14 by sticker stick together with shell 1.
The invention also discloses a kind of laser alignment instrument, comprise body (not shown) and modular structure mentioned above, wherein modular structure is arranged in the body.Have the laser alignment instrument of this modular structure, the good stability of its shoot laser, the maintenance of kernel 2 also makes laser spots or laser rays not have the vibration of slight amplitude.
According to modular structure of the present invention, can 3 fixing module kernels 2 be passed through, even if make module kernel 2 after various environmental test still can be well fixed, very there is practical value.Modular structure of the present invention can also pass through perforate 17 above groove 14, thus makes the operation of invocation point glue convenient.
Should be noted that, embodiments of the invention have preferably implementation, and not any type of restriction is done to the present invention, any person skilled in art of being familiar with may utilize the technology contents of above-mentioned announcement change or be modified to equivalent effective embodiment, in every case the content of technical solution of the present invention is not departed from, the any amendment done above embodiment according to technical spirit of the present invention or equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
