Abstract
The utility model relates to a double focus reflector used in laser application field, which comprises a reflector holder (1) and a mirror surface fixed each other, wherein, the mirror surface comprises an upper curved surface (2), a lower curved surface (3) and a dislocation plane (4); the dislocation plane is connected between the lower end of the upper curved surface and the upper end of the lower curved surface; the upper curved surface and the lower curved surface are concaves of the same type; the dislocation plane is parallel to a rotating shaft (5); in addition, the breadth of the dislocation plane is proportional to the focal distance of the double focus reflector. The utility model adopts two focusing concave surfaces as mirror surfaces and laser beam can form into two focuses on focusing surface after being reflected by the two mirror surfaces arranged on the reflector; thereby, during laser welding or laser powder injection welding, flow stability of laser welding bath can be improved so as to improve welding quality; moreover, processing evenness of laser surface heat treatment, laser quenching, laser cladding and laser spray coating can also be improved.
Description
Technical field
The utility model relates to laser application bifocus catoptron.
Background technology
At present, laser bonding, laser dust welding, laser surface thermal treatment, laser quenching, laser spraying etc. utilize high energy laser beam connect processing with the surface-treated industry, high-power laser beam is assembled two kinds of methods below the general employing: a kind of is with sphere or aspheric surface (as parabola, elliptical area, hyperboloid etc.) reflect focalization mirror, but this reflect focalization mirror can only be converged to laser beam a focus; Another kind is to use wedge reflector, it is with the level crossing that certain angle is arranged incoming laser beam to be reflexed on the focus lamp to focus on, thereby obtain two separated focuses, because this wedge reflector need be introduced extra catoptron, increase is to the absorption of laser beam, and causes the loss of laser energy.
Summary of the invention
The utility model has overcome the defective that original laser focusing catoptron only produces a focus and can cause the laser energy loss, and a kind of bifocus catoptron is provided.This bifocus catoptron meets the needs of production by original laser beam directly being converged to two focuses, reduces the purpose of laser energy loss simultaneously.
The utility model is achieved in that a kind of bifocus catoptron, comprises microscope base and minute surface, and for fixedlying connected, minute surface is made up of top-surface camber, lower surface camber and dislocation plane between microscope base and minute surface, is connected with the dislocation plane between the lower end of top-surface camber and the upper end of lower surface camber.
Above-mentioned a kind of bifocus catoptron, top-surface camber and lower surface camber are concave surface of the same type.
Above-mentioned a kind of bifocus catoptron, the dislocation plane is parallel with revolving shaft.
Above-mentioned a kind of bifocus catoptron, the width on dislocation plane is directly proportional with bifocal focal length.
Principle of work of the present utility model is that mirror mirror adopts two sections to focus on concave curved surfaces, and laser beam produces two focuses on focusing surface after two sections direct reflections on the catoptron; Can be as requested, select for use the bifocus catoptrons of different dislocation plane width to satisfy when operating needs to different focal.In laser bonding or laser dust welding, can improve the stability that flows in the laser bonding molten bath thus, thereby improve welding quality; In laser surface thermal treatment, laser quenching, laser cladding and laser spraying, can improve the homogeneity of processing.
Description of drawings

Wherein, 1 is microscope base, and 2 is top-surface camber, and 3 is lower surface camber, and 4 are the dislocation plane, and 5 is revolving shaft.
Embodiment
Embodiment of the present utility model is provided by accompanying drawing.
Referring to Fig. 1, shown in Figure 2, a kind of bifocus catoptron comprises microscope base 1 and minute surface, between microscope base 1 and minute surface for fixedlying connected, minute surface is made up of top-surface camber 2, lower surface camber 3 and dislocation plane 4, is connected with the dislocation plane between the upper end of the lower end of top-surface camber 2 and lower surface camber 3; Top-surface camber 2 is a concave surface of the same type with lower surface camber 3; Dislocation plane 4 is parallel with revolving shaft 5; The width on dislocation plane 4 is directly proportional with bifocal focal length.In the present embodiment, top-surface camber 2 in the bifocus catoptron, lower surface camber 3 and dislocation plane 4 are by the moulding of rotary type high precision machine tool time processing, manufacturing process is simple like this, can improve the anti-high-power laser beam of bifocus catoptron and heat dissipation capability and focusing quality simultaneously.
