Description

Technical Field

[0001] The utility model belongs to the technical field of automobile component processing, and particularly relates to an auxiliary feeding device for an engine cylinder body. Background Art

[0002] The engine cylinder auxiliary feeding device is an auxiliary equipment specially used in the processing of automobile engine cylinder blocks. It is designed to improve feeding efficiency, ensure feeding accuracy and protect the cylinder block. When feeding is required, the auxiliary lifting structure lifts the cylinder block to the vicinity of the processing equipment, and the pneumatic control mechanism drives the top support plate to rise or fall through the cylinder, so that the locating pin is aligned with the locating hole on the cylinder block to achieve precise positioning of the cylinder block.

[0003] For example, a Chinese patent with publication number CN214237310U discloses a cylinder body turning auxiliary loading platform, including a machine base, a lifting mechanism is fixed in the middle of the machine base, a supporting plate is arranged on the lifting mechanism, at least two positioning core shafts are fixed on the supporting plate, and a slide rail is respectively arranged on the front and rear sides of the machine base, a left turning seat and a right turning seat that can slide left and right along the slide rail are arranged, a rotating shaft is arranged on the top of the left turning seat and the right turning seat, the inner end of the rotating shaft is connected to a turning disk, and at least two turning core shafts are fixed on the inner wall of the turning disk.

[0004] The above-mentioned cylinder auxiliary feeding device effectively improves production efficiency, saves labor resources, and improves operational safety, but there are still some defects that need to be improved. The sizes of the positioning mandrel and the turning mandrel are fixed. However, due to slight differences in the apertures of the engine cylinder, this causes the positioning mandrel and the turning mandrel to often become loose when inserted into the engine cylinder hole. This looseness will directly lead to the inability to firmly fix the engine, thereby affecting the loading process of the engine, which not only reduces work efficiency but may also cause potential damage to the equipment. In addition, the stripping plate also lacks the necessary shock absorbing device. During the frequent operation of the heavyweight component of the engine cylinder, it is easy to cause impact on the equipment, thereby affecting the smoothness and safety of the operation.
