Embodiment 1

[0024] A tool for measuring the wall thickness of a casting, including an upper seat, a base, a reset mechanism, a push rod, and a ratchet block.

[0025] The outer contour of the upper seat and the base can be cylindrical or cuboid, the diameter and side distance of the upper seat and the base are consistent, the size can be 40-100mm, the height of the upper seat can be 9-25mm, and the thickness of the base can be 1-5mm. There are screw holes on the top, and they are fastened together by screw connection.

[0026] The inside of the upper seat is provided with a first ladder structure and a second ladder structure. The first ladder structure is a cuboid with a square cross section, side length 10-30mm, and height 8-20mm; the spine block set in the first ladder structure is a cuboid with a square cross-section, height 4-10mm, and one side of the spine block. There is a sawtooth block on the top, the height of each sawtooth on the sawtooth block is 1-2mm, the length of the sawt...

Embodiment 2

[0029] The upper seat 2 of the casting wall thickness tool in the present embodiment is a cylinder, and a circular base 4 is arranged correspondingly. The uppermost end of the upper seat 2 and the base 4 are symmetrically provided with screw holes on both sides of the horizontal centerline, and are screwed by the top screw 6. Upper seat 2 and base 5 are fastened together.

[0030] Boss is designed at the very center of base 5, and stage clip 4 is connected and fastened on the boss, and the radius of the inner ring of stage clip 4 is consistent with the radius of the boss of the base.

[0031] A stepped structure is provided inside the upper seat 2 , including a first stepped structure 13 and a second stepped structure 15 . The uppermost part of the upper seat 2 is provided with a through hole downwards via the vertical center line, and the ejector rod 1 can rotate up and down inside. The ejector rod 1 is provided with a top wire 6 and a sleeve along the center line. On the on...

Abstract

The invention relates to a tool for measuring the wall thickness of a casting. The tool comprises an upper base, an ejector rod, a ratchet block, a reset mechanism and a base; a stepped structure is arranged in the upper seat; the stepped structure is matched with the resetting mechanism and the ratchet block; a through hole is formed in the middle of the upper base, and the ejector rod penetratesthrough the through hole to be connected with the ratchet block; scale marks are arranged on the ejector rod; and the upper seat is buckled on the base. The tool for measuring the wall thickness of the casting overcomes the problems that in the prior art, a measuring tool cannot be directly used for measuring the interior of a cavity, and the wall thickness of the casting is not measured accurately, achieves measurement of the wall thickness of the interior of the cavity of the casting, and is small in measurement result error and convenient to use.

Description

technical field [0001] The invention relates to a measuring tool, more particularly to a measuring tool used for measuring the wall thickness of a casting in the process of casting a core. Background technique [0002] The inner cavity of castings generally has a staggered and continuous structure, especially for engine castings, which have strict wall thickness requirements such as oil cavity and water cavity, and the tolerance range is within 2mm. At the same time, because of its special shape, the process In the design, one sand core must be formed by completely covering another sand core, which leads to the inability of general measuring tools to penetrate into the cavity to complete the measurement of the distance (wall thickness) between the two sand cores. In order to solve this problem, the existing measurement method generally puts mud balls on the top surface of the sand core at the bottom layer, and utilizes the shaping ability of the mud balls to provide feedback...
