Abstract

The utility model relates to a laser processing device, which comprises optical lenses, a lens cone and the rotary supporting device, wherein, the optical lenses are plano lenses that can penetrate the laser beams emitted by a laser, and a holding rack of the lenses is provided with two supporting axles that are sheathed in coaxial holes on the wall surface of the rotating lens cone, so that a revolution support by which the plano lenses can rotate around the supporting axles is formed. The holding rack of the plano lenses is additionally connected with a rotating rod for regulating the arrangement angles of the plano lenses as required. The plano lenses can cause incoming laser beams to move horizontally in axial lines with unchanged directions, and holes that are processed to form on workpieces are straight holes and have the advantages of small laser energy loss.

Description

The rotating mirror apparatus that is used for Laser Processing

The utility model relates to the device that is used for Laser Processing.

In existing laser processing device, usually need laser beam is rotated, for use in cutting processing greater than hole of lasing beam diameter etc.Following method can make laser beam rotate in the prior art: disclose a kind of device that is used for LASER HEAT TREATMENT processing among the CN85204571, this device rotates light-guiding mechanism with one, plane mirror is rotated as axis with the incoming laser beam optical axis, thereby realize the function of reflection lasering beam at surface of the work picture circle; Regulate the angle of border, plane and incident light, can change drawn radius of a circle.The advantage of this method is to implement fairly simplely, and the laser energy loss is little; But because folded light beam and surface of the work have an angle, therefore the inner surface in the hole that is processed to form is a taper seat, that is to say that the hole of getting is not a straight hole, but a taper hole, this can not satisfy instructions for use in many occasions.If replace plane mirror to rotate as axis, also can realize making the transmission laser bundle to draw round function, but there is the defective of taper hole equally in it at surface of the work with the incoming laser beam optical axis with prism wedge.The also existing method of using the rotation combined prism in the prior art promptly can make the transmission laser bundle be implemented in the function that surface of the work is drawn circle with on the device of incoming laser beam optical axis as the axis rotation with two parallel being placed in relative prism inclined-plane.In this method, laser beam vertically is mapped on the surface of the work, and therefore the hole of getting is a straight hole.Its shortcoming is, laser beam passes two lens interface, and energy loss is bigger, and the depth of parallelism of regulating two prism inclined-planes difficulty comparatively.

The purpose of this utility model is, provides a kind of and uses a level crossing to make the transmission laser bundle can beat straight circular hole and the less device of laser energy loss on workpiece.

The purpose of this utility model is realized by following mode.

The utility model is used for the rotating mirror apparatus of Laser Processing, include optical frames, lens barrel and supporting whirligig thereof, it is characterized in that, described optical frames is the planar lens that can see through the laser beam of used laser instrument ejaculation, for example quartzy planar lens, quartzy planar lens etc., be provided with the bolster of two coaxial lines on the holding frame of this mirror, this two bolster is set in the hole of the coaxial line on the revolving mirror tube wall surface, and constituting planar lens can be around the pivoting support of this bolster rotation; Also be connected with a dwang that is used for adjusting angle on the holding frame of planar lens, the other end of this bar is stretched outside the lens barrel wall; On the periphery of this bar, be provided with the screw thread that matches with circular lens barrel cinclides internal thread.

The rotating mirror apparatus that is used for Laser Processing of the present utility model when carrying out Laser Processing, can be regulated the angle that is provided with of planar lens as required.Because laser beam passes on the surface that planar lens promptly is mapped to workpiece, laser beam axis and planar lens plane of incidence are when non-perpendicular state, the effect of planar lens makes incident beam axis generation translation, its direction still remains unchanged, therefore, as long as the vertical workpiece to be machined of the laser beam axis surface penetrated from laser instrument, then its hole of being processed to form on workpiece promptly is a straight hole.The angle difference of its inclination, then Jia Gong aperture is inequality.Because laser beam only passes a planar lens, the middle compared to existing technology combined prism that uses has the little advantage of laser energy loss in this device.

Be further described below by embodiment and accompanying drawing thereof.

Fig. 1 is a kind of example structure schematic diagram of the present utility model.

Referring to Fig. 1, (1) is circular lens barrel, and it is bearing on the base (2) by rolling bearing (3).Be equipped with motor (6) on this base, belt pulley (5) is installed on the electric machine main shaft, with belt pulley opposite position place one groove is arranged on the outside wall surface of circular lens barrel, belt (4) is placed on wherein.Then driving circular lens barrel by the belt transmission behind the electric motor starting rotates with the speed of needs.(8) be planar lens, periphery at this mirror is provided with support frame, also be fixedly connected with a horizontal supporting axle (9) respectively on the support frame at both sides places, they are set in the coaxial line hole on the revolving mirror tube wall surface, and described planar lens can be turned an angle around this bolster; (10) be and the contacted dwang that is used for adjusting angle of planar lens holding frame, the other end of this bar is stretched outside the lens barrel wall, be provided with screw thread on the periphery of this bar, it matches with the internal thread of circular lens barrel cinclides, can regulate the angle of planar lens when rotating this bar with hand.(7) for being arranged on the extension spring between lens barrel wall and the lens support frame bottom, it is in order to the aiding support lens.Also can use Movable loop to be connected with the touching position of holding frame at dwang in actual use, not separate to guarantee both, can remove the aiding support extension spring this moment from.

Claims (2)

1. rotating mirror apparatus that is used for Laser Processing, include optical frames, lens barrel and supporting whirligig thereof, it is characterized in that, described optical frames is the planar lens that can see through the laser beam of used laser instrument ejaculation, on the holding frame of this mirror, be provided with the bolster of two coaxial lines, this two bolster is set in the hole of the coaxial line on the revolving mirror tube wall surface, and constituting planar lens can be around the pivoting support of this bolster rotation; Also be connected with a dwang that is used for adjusting angle on the holding frame of planar lens, the other end of this bar is stretched outside the lens barrel wall.
