AI Technical Summary
When inspecting the diameter and position of the spherical end face of a part, the existing inspection tool uses screws and pins to fix the mandrel and template together, which makes template replacement cumbersome and affects convenience and inspection efficiency.
The template adopts a fixed box and slider structure, and uses the cooperation of the first spring and the slider to realize the quick disassembly and installation of the template. Combined with the telescopic rod and the second spring, the ease of template disassembly is improved, and the template is protected by a protective sleeve to avoid deformation and ensure the accuracy of testing.
It enables quick template replacement and protection, improves the convenience of inspection tools and the accuracy of inspection, and meets the quality control needs of mass production.

Abstract
Claims
1. A ball diameter and location degree gauge, comprising a mandrel (1), characterized in that: The mandrel (1) has an installation groove (2) inside, and a template (3) is set inside the installation groove (2) by a fixing component. The lower end of the template (3) has an arc-shaped surface. The fixing component includes a fixing box (5), which is fixedly installed on the side wall of the mounting groove (2). The template (3) has a fixing hole (6) inside, which is adapted to the fixing box (5) and the fixing hole (6). The fixing box (5) has a sliding groove inside, and a fixing shaft (7) is fixedly installed inside the sliding groove. Two sliders (8) are slidably installed on the outer ring of the fixing shaft (7), which are adapted to the sliding groove. A pressure block (10) is fixedly installed at the end of the slider (8), and the end of the pressure block (10) has a fan-shaped structure. A first spring (9) is fixedly connected between the two sliders (8), and the first spring (9) is movably sleeved on the outer ring of the fixing shaft (7). The template (3) is provided with protective components.
2. A ball diameter and position gauge according to claim 1, wherein: The central axis of the mandrel (1) and the vertical center line of the arc surface are on the same vertical line.
3. A ball diameter and position gauge according to claim 1, wherein: The end of the pressure block (10) is fixedly provided with a push plate (11). In the initial state, the pressure block (10) protrudes from the end of the fixed box (5) and fits against the template (3).
4. A ball diameter and position gauge according to claim 2, wherein: Two sleeve rods (12) are fixedly arranged on the surface of the mandrel (1). The sleeve rods (12) and the template (3) are perpendicular to each other. A telescopic rod (13) is slidably arranged inside the sleeve rods (12). A second spring (14) is fixedly connected between one end of the telescopic rod (13) inside the sleeve rod (12) and the inner wall of the sleeve rod (12). The other end of the telescopic rod (13) extends into the interior of the mounting groove (2).
5. A ball diameter and position gauge according to claim 4, wherein: The two sleeve rods (12) are symmetrically distributed about the center line of the fixed box (5).
6. The ball diameter and position gauge according to claim 1, characterized in that: The protective component includes a limiting groove (15), and there are two limiting grooves (15). The two limiting grooves (15) are respectively opened on the two sides of the template (3). A limiting block is slidably arranged inside the limiting groove (15). A protective sleeve (16) is fixedly connected between the two limiting blocks. The protective sleeve (16) is slidably sleeved on the outside of the template (3). The lower end of the protective sleeve (16) has an arc-shaped structure. A screw (17) is threadedly connected inside the limiting block. A through hole is opened on the side of the protective sleeve (16) for the screw (17) to move through.
7. A ball diameter and position gauge according to claim 4, wherein: The outer ring at the upper end of the mandrel (1) is fixedly provided with anti-slip texture (4).
