A detachable fixture seat is installed on one side of the fixture platform on the fixture base. The side of the detachable fixture seat facing the fixture platform has an arc-shaped surface structure with several positioning grooves evenly distributed on the arc-shaped surface structure.
[0006] The fixture base has a U-shaped groove corresponding to the position of the detachable fixture seat. The inner walls on both sides of the U-shaped groove have slides. The lower ends of the two side walls of the detachable fixture seat have sliders, which are installed in the corresponding slides.
[0007] The upper end of the arc-shaped structure of the detachable fixture base is chamfered.
[0008] The beneficial effects of this utility model are: the detachable fixture base in this utility model is detachable and can be adjusted at will to achieve the ideal measurement position; it can measure the roughness of two positions of the component; using the fixture to fix the component makes the measurement data more accurate, while saving manpower.

[0015] It should be noted that when a component is described as "fixed to" another component, it can be directly on the other component or may have a component in between. When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.
[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0018] like Figures 1 to 3 As shown, an auxiliary measurement fixture for an ETCH process focusing ring component includes a fixture base 1, a receiving hole 2, a fixture platform 3, a detachable fixture seat 4, an arc-shaped surface structure 5, a positioning groove 6, a U-shaped groove 7, a slide rail 8, and a slider 9.
[0019] The fixture base 1 has a receiving hole 2 and a fixture platform 3. A detachable fixture seat 4 is installed on one side of the fixture platform 3 on the fixture base 1. The side of the detachable fixture seat 4 facing the fixture platform 3 is an arc-shaped surface structure 5 and several positioning grooves 6 are evenly distributed on the arc-shaped surface structure 5.
[0020] The fixture base 1 is provided with a U-shaped groove 7 corresponding to the position of the detachable fixture seat 4. The inner walls on both sides of the U-shaped groove 7 are provided with slide rails 8. The lower ends of the two side walls of the detachable fixture seat 4 are provided with sliders 9, and the sliders 9 are installed in the corresponding slide rails 8.
