Description

Technical Field

[0001] The utility model belongs to the technical field of engine parts detection, and in particular relates to a symmetry detection device for a connecting rod of a variable compression ratio engine. Background Art

[0002] The engine connecting rod is composed of the small connecting rod head, the connecting rod body and the large connecting rod head. It is one of the key parts of the engine and is used to withstand complex stress, impact vibration and heavy load working conditions where the design quality is limited. If the engine connecting rod fails or is damaged, it will directly lead to a serious level of product accidents or system function failure. The engine connecting rod is manufactured by a pair of upper and lower molds. During the manufacturing process, some connecting rods will form front and back, left and right mold errors due to mechanical reasons, that is, the upper and lower molds are asymmetrical.

[0003] Therefore, after the engine connecting rod is demoulded, it is necessary to perform a symmetry inspection on it. Most existing inspection devices place the connecting rod on a conveyor belt, transport it to an industrial camera, take a picture of it with an industrial camera, and then compare the image information to complete the inspection. However, placing the connecting rod directly on the conveyor belt cannot ensure that the connecting rods are placed on the same horizontal line, which is easy to affect the shooting effect of the industrial camera. Utility Model Content

[0004] The utility model provides a variable compression ratio engine connecting rod symmetry detection device, aiming to solve the problem that the detection device proposed in the above background technology cannot position and place the connecting rod, thus easily affecting the subsequent industrial camera shooting.

[0014] 2. A set of clamping blocks are driven to slide by the driving mechanism, thereby clamping or releasing the connecting rod, so as to facilitate the rapid unloading of the connecting rod. The setting of the anti-slip pad can effectively ensure that the connecting rod will not be separated from the clamping block, and the anti-slip effect is good. The industrial camera is connected through the U-shaped plate, which is convenient for the subsequent removal of the industrial camera for inspection or replacement, and the operation is relatively fast;

[0015] 3. The connection block is limited by the limit plate, so that a group of U-shaped plates can be assembled. The assembly is relatively quick and convenient for the subsequent disassembly of the U-shaped plates.
