Description

Guide structure of laser nozzle

The invention relates to a guide structure of a laser spray head, in particular to an invention in which the spray head and the base are in contact with each other by a slope, so that the spray head and the base can be stably combined.

Referring to the sixth figure, the conventional laser nozzle is assembled by providing a base (A) with a first screwing portion (A1) and a nozzle (B) with a second screwing portion (B1). The first screw connection portion (A1) and the second screw connection portion (B1) are screwed together, so that the spray head (B) is coupled to the base (A).

Referring to the seventh figure, the conventional laser nozzle has the following defects:

1. Due to the tolerance of machining, when the first screw joint (A1) and the second screw joint (B1) are screwed together, a gap may be formed between adjacent teeth, and this gap It may cause slight vibration of the nozzle (B) during laser processing, which will affect the precision of the machined part.

2. Laser processing usually produces high temperatures, and the known nozzle has a lack of poor heat dissipation.

3. During processing, the cut workpiece may hinder the displacement of the laser nozzle due to the poor drop position, causing the laser nozzle to collide with the workpiece, causing equipment damage.

Therefore, the present invention proposes a guide structure for a laser spray head with a stable combination of a spray head and a base, including: a base having a screw hole, the screw hole having an insertion opening, and the base having a first abutment slope at the screw hole A nozzle, a bearing surface, and a screw connection portion extending from the bearing surface, and a second abutment inclined surface between the bearing surface and the screw connection portion; the nozzle uses the screw connection portion The screw is screwed into the screw hole of the base, and the second abutting inclined surface abuts on the first abutting inclined surface.

Further, the inclination angle of the first abutting inclined surface and the second abutting inclined surface is between 30 degrees and 60 degrees. Furthermore, the inclination angle of the first abutting inclined surface and the second abutting inclined surface is 45 degrees.

Further, the base has a plurality of radiating fins. Furthermore, the distance between adjacent heat dissipation fins is between 1.5 cm and 2.5 cm, preferably 2 cm.

Further, a circular groove is formed on the base. Furthermore, the depth of the groove is between 2 cm and 4 cm, preferably 2.5 cm.

According to the above technical features, the following effects can be achieved:

1. Solve the problem that the gap between the spray head and the base caused by the screw connection part and the screw hole is unsteady, which reduces the processing accuracy.

2. The first abutment inclined surface of the base and the second abutment inclined surface of the shower head adopt a 45-degree inclined abutment, so that the shower head can be more firmly combined on the base.

3. The high temperature generated by the nozzle due to the laser processed laser can use the heat dissipation fins to quickly dissipate heat.

4. The groove on the base can break a part of the base from the nozzle when the processing part is blocked by the moving path of the nozzle, and the user can process it again by replacing the base and the nozzle to avoid laser. The base of the nozzle is damaged due to collision with the machined part, causing greater losses.

Based on the above technical features, the main effect of the guiding structure of the laser spray head of the present invention will be clearly shown in the following embodiments.

Referring to the first figure, this embodiment includes: a base (1) for connecting a laser source [the laser source is the same as the conventional technology, so the laser source is not shown in the figure], the base (1) a screw hole (11), the screw hole (11) has an insertion opening (111), the base (1) has a first abutment slope (12) located in the screw hole (11) and adjacent to the insertion Mouth (111), the inclination angle of the first abutment inclined surface (12) is between 30 degrees and 60 degrees. In this embodiment, the inclination angle of the first abutment inclined surface (12) is 45 degrees. The base (1) is provided with a plurality of heat dissipation fins (13), and a ring-shaped groove (14) is formed on the base (1), and the distance between adjacent heat dissipation fins (13) is between 1.5 cm The depth of the groove (14) is between 2 cm and 2.5 cm, and the depth of the groove (14) is between 2 cm and 4 cm. In this embodiment, the distance between adjacent heat dissipation fins (13) is 2 cm. ) Is 2.5 cm deep. A spray head (2) has a bearing surface (21), the bearing surface (21) is provided with a nozzle (22) and a screw connection portion (23) on opposite sides, and the bearing surface (21) and the screw connection portion ( 23) There is a second abutting inclined surface (24), wherein the second abutting inclined surface (24) corresponds to the first abutting inclined surface (12), so the second abutting inclined surface (24) is in this embodiment. The tilt angle is also 45 degrees.

Referring to the second and third figures, the nozzle (2) is screwed into the screw hole (11) of the base (1) with the screw connection portion (23), and when the screw connection portion (23) When completely screwed in the screw hole (11), the second abutting inclined surface (24) will abut on the first abutting inclined surface (12).

Referring to the fourth figure, the first abutment inclined surface (12) of the base (1) and the second abutment inclined surface (24) of the shower head (2) are abutted at an angle of 45 degrees, so that the shower head ( 2) More stable integration On the base (1). This can solve the problem that the gap between the conventional nozzle (B) and the base (A) due to the screw connection part and the screw hole screwing together causes the joint of the nozzle (B) to be unstable, thereby reducing the processing accuracy. In addition, the high temperature generated by the laser processed laser of the shower head (2) can use the heat radiating fin (13) to quickly dissipate heat, so the shower head (2) will not be overheated.

Referring to the fifth figure, the groove (14) is made to a depth of 2.5 cm. When a processing part (3) blocks the moving path of the nozzle (2), a part of the base (1) and The spray head (2) is broken off from the groove (14), and the user can process again by replacing the base (1) and the spray head (2) to avoid the base of the laser spray head from colliding with the processed part ( 3) and damage, causing greater losses.
