Description

Technical Field

[0001] The utility model relates to the field of water-guided laser processing, in particular to a water-guided laser light-transmitting glass support frame with adjustable light-transmitting glass position. Background Art

[0002] Water-guided laser processing technology uses the principle of total reflection of focused laser in water beam fiber. The water beam fiber guides the laser to the surface of the workpiece, and uses the laser energy to process the workpiece. It has the advantages of small processing heat affected zone and high processing surface quality. In recent years, water-guided laser processing technology has been widely used in aerospace manufacturing, medical device manufacturing and other fields. The coupling device is an important part of water-guided laser processing equipment. Many scientific research institutions at home and abroad have designed a variety of coupling devices, but the transparent glass in the existing coupling devices is mostly non-adjustable or difficult to adjust. Because the energy density of the focused laser used in water-guided laser processing is large, the laser focus is very close to the transparent glass, and one side of the transparent glass contacts the flowing water layer, the transparent glass is easily damaged locally after a period of use. Once the part of the transparent glass where the laser passes through is damaged, if the position of the transparent glass is not adjustable, the transparent glass can only be replaced. Utility Model Content

[0003] In view of the disadvantage of the existing water-guided laser coupling device that the position of the light-transmitting glass is difficult to adjust, the utility model aims to provide a component of the coupling device, namely a water-guided laser light-transmitting glass support frame with adjustable light-transmitting glass position.

[0004] To achieve the purpose of the utility model, the utility model adopts the following technical scheme: a water-guided laser transparent glass support frame with adjustable transparent glass position, characterized in that it includes a transparent glass fixing plate, a sealing rubber ring, transparent glass, a rubber gasket, and a transparent glass bracket.

[0005] The light-transmitting glass is installed in the card slot of the light-transmitting glass bracket, and the two sides of the light-transmitting glass are in contact with the sealing rubber ring and the rubber gasket; the sealing rubber ring is installed in the rubber ring groove of the light-transmitting glass fixing plate; the rubber gasket is bonded in the card slot of the light-transmitting glass bracket; the light-transmitting glass fixing plate and the light-transmitting glass bracket are fixed by screws.

[0006] The light-transmitting glass fixing plate has two arc-shaped protrusions for positioning and two screw through holes for fastening.

[0007] The light-transmitting glass bracket has two arc-shaped grooves for positioning and two threaded holes for fastening with the light-transmitting glass fixing plate.

[0008] The light-transmitting glass bracket has four screw through holes for fastening and a cylindrical outer surface for positioning.

[0009] The centers of the light-transmitting glass fixing plate and the light-transmitting glass bracket are both provided with circular holes capable of passing the focused laser beam.

[0010] Compared with the prior art, the utility model has the following beneficial effects: the utility model proposes a water-guided laser transparent glass support frame with adjustable transparent glass position, and the transparent glass can be installed in the slot of the glass bracket in a non-clamped state and move in one direction to change the relative position of the transparent glass and the glass bracket. It has the advantages of variable transparent glass installation position, convenient and stable installation, good sealing, and extended service life of the transparent glass.

[0014] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings:

[0015] As attached Figure 1 and 2 As shown, in the embodiment of the utility model, a water-guided laser light-transmitting glass support frame with adjustable light-transmitting glass position is provided, which includes a light-transmitting glass fixing plate 1, a sealing rubber ring 2, a light-transmitting glass 3, a rubber gasket 4, and a light-transmitting glass bracket 5.

[0016] The light-transmitting glass 3 is installed in the slot of the light-transmitting glass bracket 5, and a rubber gasket 4 is arranged between the light-transmitting glass 3 and the light-transmitting glass bracket 5 to protect the light-transmitting glass 3; when not clamped, the light-transmitting glass 3 can move in one direction in the slot of the light-transmitting glass bracket 5, thereby changing the relative position of the light-transmitting glass 3 relative to the light-transmitting glass bracket 5.

[0017] The light-transmitting glass fixing plate 1 has two arc-shaped protrusions for positioning and two screw through holes for fastening, which are used to fasten with the light-transmitting glass bracket 5 by screws; the light-transmitting glass fixing plate 1 has a rubber ring groove for placing a sealing rubber ring 2, which is used to fix and clamp the light-transmitting glass 3.

[0018] The light-transmitting glass bracket 5 has two arc-shaped grooves for positioning and two threaded holes for fastening, which are used for positioning and fastening with the light-transmitting glass fixing plate 1; the light-transmitting glass bracket 5 is a part of the coupling device, has four screw through holes for fastening with the coupling device body, and has a cylindrical outer surface for positioning with the coupling device body, ensuring high-precision positioning and fastening with the coupling device body.

[0019] The centers of the light-transmitting glass fixing plate 1 and the light-transmitting glass bracket 5 are both provided with circular holes through which the focused laser beam can pass.

[0020] When in use, first place the transparent glass bracket 5 flat on the table, put the transparent glass 3 into the slot of the transparent glass bracket 5 with the rubber gasket 4, adjust the position of the transparent glass 3 so that the intact part of the transparent glass 3 can pass through the focused laser light path; install the sealing rubber ring 2 into the rubber ring groove of the transparent glass fixing plate 1, and then align the arc-shaped positioning block of the transparent glass fixing plate 1 with the arc-shaped positioning groove of the transparent glass bracket 5, and place the transparent glass fixing plate 1 on the transparent glass bracket 5. Tighten the transparent glass fixing plate 1 and the transparent glass bracket 5 with two screws. After that, place the whole on the coupling device body and fix it to the coupling device body with four screws.

[0021] During laser processing, the focused laser passes through the transparent glass 3 and irradiates the water layer below the transparent glass. Since the focus of the focused laser is very close to the transparent glass 3, the flow of the water layer and the influence of impurities in the water will affect the energy transmission of the laser, resulting in damage to the part of the transparent glass 3 located in the focused light path after a certain processing time. At this time, the position of the transparent glass 3 needs to be moved. Disassemble the coupling device body, unscrew the two screws, remove the transparent glass fixing plate 1, and adjust the position of the transparent glass 3 in the transparent glass bracket 5 so that the damaged part of the transparent glass 3 leaves the focused laser light path and the intact part moves to the focused light path. Then tighten the relevant parts and the transparent glass 3 can continue to be used.

[0022] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
