Description

Fixture for optical mirror group of laser measuring instrument

The present invention relates to a jig, in particular to a jig for an optical mirror group of a laser measuring instrument.

In the process of waterjet processing, the tool tip is measured for positioning by means of a laser measuring instrument. The laser measuring instrument includes an optical lens set arranged on the gun head of the waterjet device, and a gun tip A laser source at a location other than that used to emit laser light to an optical lens group. The laser emitted by the laser source will pass through the blade to the optical lens group and be reflected back by the optical lens group for measurement and analysis. In the foregoing process, if the laser focus point can be controlled to be close to the point of the blade point, the measurement accuracy can be improved, but the optical lens group is generally fixed to the gun head through a non-movable jig, so the optical lens cannot be adjusted. The position of the group results in that the focus position of the laser source cannot be adjusted, and the accuracy cannot be improved upward.

Therefore, the object of the present invention is to provide a jig capable of quickly adjusting the focus position of a laser source.

Therefore, the new type of fixture for an optical lens group of a laser measuring instrument is set on a gun head, defining a first horizontal direction, a second vertical direction perpendicular to the first direction and extending up and down, and a horizontal The third direction is perpendicular to the first direction and the second direction. The jig includes a base body disposed on the gun head, a first moving member that is adjustablely disposed on the base body and movable in the first direction, and a ground that is adjustable and movable along the second direction. A second moving member provided on the first moving member, and a third moving member provided on the second moving member that can be adjusted to move in the third direction. The third moving member is fixedly disposed by the optical lens group.

The effect of the novel model is that the user can adjust the first moving member, the second moving member, and the third moving member along three axes to quickly adjust the position of the optical lens group, so that the laser source During the positioning measurement, the laser focus point can be controlled to be close to the position of the blade point, so as to quickly adjust the focus position of the laser source and improve the positioning accuracy.

Referring to FIG. 1 and FIG. 2, an embodiment of the novel jig 2 for the optical lens group 11 of the laser measuring instrument 1 is provided on the side of a gun head of a waterjet device (not shown). A horizontal direction and a first direction A extending forward and backward, a second direction B which is perpendicular to the first direction A and extending up and down, and a third horizontal and perpendicular to the first direction A and the second direction B extending left and right Direction C. The jig 2 includes a base 3 fixed on one of the left or right side of the gun head, a first moving member 4 movably disposed along the first direction A on the outside of the base 3, and a The second moving member 5 is movably disposed on the front side of the first moving member 4 and a third moving member 6 is movably disposed on the lower side of the second moving member 5 in the third direction C. .

The first moving part 4 includes a frame 41 defining a slide groove 410, two bolts 42 passing through the slide groove 410 and locked on the base body 3, and a lock fixed on the outside of the frame 41 and along the frame 41 A socket 43 extending in the second direction B, and a guide rail 44 fixed to the socket 43 and also extending in the second direction B. The sliding groove 410 extends along the first direction A. When the bolts 42 are locked, the frame 41 can be fixed on the base 3 to position the frame 41. When the bolts 42 are loosened, the user can drive the frame 41 to move forward and backward along the slide groove 410 .

The second moving member 5 includes a movable block 51 disposed on the guide rail 44, a carrier 52 fixed to the front side of the movable block 51 and extending upward and forward, and a slide fixed to the lower side of the carrier 52. Rail 53. The movable block 51 is provided with a fine adjustment screw 511 and a tightening screw 512. When the tightening screw 512 is locked, the movable block 51 can be fixed on the guide rail 44 to locate the movable block 51. When loosening, use The user can move the movable block 51 up and down along the guide rail 44 by turning the fine adjustment screw 511. The slide rail 53 is disposed on a portion of the carrier 52 extending forward, and protrudes downward and extends along the third direction C.

Referring to FIG. 1, FIG. 2, and FIG. 3, the third moving member 6 includes a slider 61 provided on the slide rail 53, and a slider 61 fixed on a lower side of the slider 61 and used for fixing the optical lens group 11. Set the fixed table 62. The slider 61 is recessed from the upper surface to form an extension groove 611 extending along the third direction C and for the slide rail 53 to be embedded. In this embodiment, the extension groove 611 is a dovetail groove and the slide rail 53 For dovetail. The slider 61 is also provided with a fine adjustment screw 612 and a tightening screw 613. When the tightening screw 613 is locked, the slider 61 can be fixed on the slide rail 53 to position the slider 61. The user can rotate the fine adjustment screw 612 to drive the slider 61 to move left and right along the slide rail 53.

The user can adjust the position of the optical lens group 11 in three axial directions, such as the first direction A, the second direction B, and the third direction C, so as to control the laser focusing point close to the knife of the gun head. The position of the sharp point, thereby achieving the effect of quickly adjusting the focus position of the laser source, and improving the positioning accuracy.

In summary, the new model can be adjusted to move along three axes to adjust the position of the optical lens group 11 to achieve the effect of quickly adjusting the focus position of the laser source and improving the positioning accuracy. Can achieve the purpose of new cost.

However, the above are only examples of the new model. When the scope of implementation of the new model cannot be limited by this, any simple equivalent changes and modifications made in accordance with the scope of the patent application of the new model and the content of the patent specification are still Within the scope of this new patent.
