Problems solved by technology
In order to ensure that the factory-made cylinder head has the wall thickness of the directional water hole that meets the standard, the existing technology is to dissect the cylinder head and measure it or use a three-coordinate measuring machine to detect it. However, the measurement after dissection is destructive, resulting in increased costs. A three-coordinate measuring machine is used. The detection is limited by the number of inspected, and the detection cost is high, which needs to be improved urgently

The invention discloses a tool for detecting wall thickness of an oriented water hole in a cylinder cover. The tool comprises two handles, a dial indicator, a chassis and a contact block, wherein the two handles are respectively arranged on a fixed inserting strip and a movable inserting strip; the dial indicator passes through the fixed inserting strip and the movable inserting strip and is arranged on the fixed inserting strip and the movable inserting strip; a second bushing is placed at the bottom of the chassis through a bolt; the chassis is connected with the fixed inserting strip and the movable inserting strip through a mandrel, a flat washer, a hexagon thin nut and a first bushing; and the contact block is fixed on the chassis through a cross recessed hemispherical head screw and a hexagonal nut. According to the tool for detecting the wall thickness of the oriented water hole in the cylinder cover, the detection can be completed without damaging the cylinder cover and is not limited by the amount of detecting; and one-by-one detection can be realized by the tool, thus the cost can be reduced.
Description
technical field [0001] The invention relates to a tool for checking the wall thickness of a directional water hole inside a cylinder head. Background technique [0002] The diesel engine cylinder is composed of a cylinder block and a cylinder head. The cylinder head has directional water holes, and the wall thickness of the directional water holes is closely related to the working performance and quality of the cylinder head. In order to ensure that the factory-made cylinder head has the wall thickness of the directional water hole that meets the standard, the existing technology is to dissect the cylinder head and measure it or use a three-coordinate measuring machine to detect it. However, the measurement after dissection is destructive, resulting in increased costs. A three-coordinate measuring machine is used. The detection is limited by the number of inspected, and the detection cost is high, which needs to be improved urgently. Contents of the invention [0003] In ...
