Embodiment Construction
[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0020] see Figure 1 to Figure 4 , the present invention provides a technical solution: a variable range part wall thickness measurement tool, comprising a main arm 1, the right end of the main arm 1 is fixedly connected with an auxiliary arm 2, the main arm 1 and the auxiliary arm 2 are perpendicular to each other, and the main arm A right-angle iron 3 is connected to the left end of 1. There are limit blocks 111 inside the main arm 1. There are seven limit blocks 11 and they are arranged at equal intervals. Pin 9, the main arm 1 is connected with the right-angle iron 3 through the limit pin 9. By adjusting the length of the right-angle i...

The invention discloses a variable-range part wall thickness measuring tool, and relates to the technical field of casting measurement, in particular to a variable-range part wall thickness measuring tool which comprises a main arm, the right end of the main arm is fixedly connected with an auxiliary arm, the main arm and the auxiliary arm are perpendicular to each other, the left end of the main arm is movably sleeved with right-angle iron, and the right-angle iron is fixedly connected with the auxiliary arm. A first movable rod is movably connected into the right-angle iron in a sleeved mode, an ejector pin is fixedly connected to the right side of the first movable rod, and a second movable rod is movably connected into the auxiliary arm in a sleeved mode. According to the part wall thickness measuring tool with the variable range, the length of the main arm can be adjusted by adjusting the length of the right-angle iron in the main arm, castings with different thicknesses can be measured, then the length of the second movable rod in the auxiliary arm can be adjusted, the length of the auxiliary arm can be adjusted, different parts of the castings can be conveniently measured, and the measurement accuracy is improved. The device effectively adapts to casting molds of different specifications, and is simple in structure and convenient to operate.
Description
technical field [0001] The invention relates to the technical field of casting measurement, in particular to a variable-range part wall thickness measurement tool. Background technique [0002] Castings are metal forming objects obtained by various casting methods, that is, the smelted liquid metal is injected into the pre-prepared casting mold by pouring, injection, suction or other casting methods, and after cooling, after grinding and other subsequent processing methods. , the resulting object of certain shape, size and properties. [0003] For castings with large external dimensions, taking marine diesel engine castings as an example, it is difficult to measure the wall thickness of some key positions. Ultrasonic measurement is usually used. However, for gray iron castings, ultrasonic measurement errors are large. For this reason, we provide a Variable range part wall thickness measurement tool. SUMMARY OF THE INVENTION [0004] In view of the deficiencies of the pri...
