specific Embodiment approach 1

[0028] Specific implementation mode 1, refer to Figure 1 to Figure 6 Describe this embodiment in detail, a kind of atmospheric plasma jet machining tool setting device described in this embodiment, it comprises machine tool 5, and machine tool 5 comprises machine tool control system 5-1 and plasma jet emission device 5-2; Machine tool control system 5-1 is used to record the movement distance of the workbench of the machine tool 5; the plasma jet emission device 5-2 is located above the workbench of the machine tool 5;

[0029] It also includes a base 1, a fused silica piece 2, a connecting pipe 3 and a pressure sensor 4;

[0030] The upper surface of the base 1 is provided with a groove, the fused silica sheet 2 is fixedly arranged in the groove of the base 1, and the center of the fused silica sheet 2 is provided with a through hole 2-1;

[0031] The upper surface of the base 1 is provided with a channel 1-4, and the channel 1-4 includes a vertical channel 1-4-1 and a hori...

specific Embodiment approach 2

[0037] Specific Embodiment 2. This embodiment is a further description of the tool setting device for atmospheric plasma jet processing described in Embodiment 1. In this embodiment, a cooling cavity 1-3 is provided in the base 1 and is located in the channel Below the base 1-4; the outer surface of the base 1 is provided with a water inlet 1-1 and a water outlet 1-2 connected with the cooling chamber 1-3; the cooling chamber 1-3 is used to feed cold water to cool the fused silica sheet 2;

[0038] The water inlet 1-1 and the water outlet 1-2 are used to allow cold water to enter and exit from the cooling chamber 1-3.

[0039] In this embodiment, due to the high temperature of part of the atmospheric plasma jet, the fused silica sheet 2 will be melted and deformed without cooling. Therefore, water cooling is required to work under the high-temperature plasma jet with a temperature range of 800°C to 3000°C. The cold water enters the cooling cavity 1-3 from the water inlet 1-1, an...

Abstract

The invention relates to a tool setting device for atmospheric plasma jet machining, belonging to the field of optical fine machining, and solving the problem of tool setting of atmospheric plasma jet. The tool setting device comprises a base, a fused quartz piece, a connecting pipe and a pressure sensor, wherein a groove is formed in the upper surface of the base, and the fused quartz piece is fixedly arranged in the groove of the base; a through hole is formed in the fused quartz piece, and a channel is formed in the upper part in the base and is L-shaped; one end of the channel is communicated with the through hole, and the other end of the channel penetrates through the outer side surface of the base and is connected with one end of the connecting pipe; the other end of the connecting pipe is connected with the pressure sensor. The tool setting device is suitable for other occasions needing to set tools.

Description

technical field [0001] The invention relates to the field of precision optical processing, in particular to a tool setting device for atmospheric plasma jet processing. Background technique [0002] Atmospheric plasma processing method is used to process optical lenses, the removal rate is high, and no sub-surface damage occurs. It belongs to a non-sub-surface damage processing method. This method can realize high-precision curved surface processing, and the atmospheric plasma processing method is used to process workpieces. , first of all to achieve accurate tool setting. [0003] When the workpiece is processed, the working gas of this method generates a plasma jet, which is sprayed onto the surface of the workpiece, thereby realizing processing. However, because the plasma jet is a kind of fluid, the traditional contact tool setting cannot be used, and because of the presence of various active particles, photon excitation, and specific spectral characteristics, the photo...
