The utility model content

The purpose of this utility model is to change in original laser device design, can only provide the reflection unit of the scalable in a kind of laser device by regulating the request for utilization that laser instrument self satisfies instruments design.Requirement can either be loosened, the precision of laser device design needs can be satisfied again the laser instrument profile.

In order to realize above purpose, the technical solution adopted in the utility model is:

Scalable reflection unit in the laser device is characterized in that: be included in the mirror unit on the reflector mount of being fixed on that is provided with on the laser beam path of generating laser, catoptron is fixed on the mirror unit.

Described mirror unit is provided with groove and two threaded holes.

When described generating laser has 4, a mirror unit that is fixed on the reflector mount all is set on the laser beam path of each generating laser, catoptron is fixed on the mirror unit.The shared reflector mount of described 4 mirror units.Described reflector mount is a T type structure, is made up of four square sides, and four threaded holes are arranged on each square sides, and four through holes are arranged on the middle position of reflector mount.

In a laser device (as the laser dotting instrument), in laser socket, be assembled with four generating lasers, be used to launch four bundle glancing incidence laser beam A, A1, A2, during A3, described scalable reflection unit is designed to have on the reflector mount 4 mirror units, the form of fixing a catoptron on each mirror unit.Each mirror unit of this device is assembled in the front end of each laser emitting mouth, fixing catoptron is located at the glancing incidence laser beam A that four bundles are launched by generating laser respectively on it, A1, A2, on the light path of A3, this laser beam is distinguished up and down after passing through reflection of catoptron, left and right four direction outgoing four bundle reflect beams of laser light B, B1, B2, B3.By the fillister head screw of each side and the position that holding screw is adjusted each mirror unit respectively on pine or the tight reflector mount, thereby adjust the position of catoptron fixing on each mirror unit, reach and adjust four bundle laser beam B respectively, B1, B2, the purpose of the light beam precision of B3 on each direction makes laser device reach certain service precision.After using this reflection unit, existing horizontal laser seat has replaced original cross laser base, loosened requirement to the laser instrument profile, improved the degree of focus of laser beam, and avoided directly on the cross laser base, adjusting the structural difficulty that degree of focus faced of laser beam, increased the stability of laser device.

Compared with prior art, the beneficial effects of the utility model are: after using adjustable reflection unit, laser device has been reduced the requirement of laser instrument from body contour, the apparatus structure design is relaxed, and the laser beam degree of focus improves.And changed in the traditional design by the corresponding screw of each laser instrument on pine or the tight cross laser base, reach the purpose of adjusting laser beam, but directly utilize the direct reflection principle to change the exit direction of laser beam, adjust the angle of catoptron again by the screw on the adjustment mirror unit, thereby adjust laser beam and reach laser beam, following laser beam plummet, the precision of design and operational requirements such as left laser beam, right laser beam level; Reduced the difficulty of adjusting operation.
