Problems solved by technology

The buffer of the original structure is complex in structure and large in size, which is not suitable for use in small automation equipment, and the seal of the traditional buffer is to process the oil seal installation groove on the bearing sleeve, and assemble the oil seal and the bearing sleeve to form a sealing structure. Because it is very difficult to process the slot hole on the bearing sleeve, the process is complicated and the yield is low. In order to improve the yield of the product, the internal structure of the buffer needs to be improved to meet the same technical requirements.

Abstract

The invention discloses a buffer convenient to machine. The buffer comprises a cylinder body, one end of the cylinder body is provided with a cylinder head, the other end of the cylinder body is provided with a bearing sleeve and a dust-sealing protecting bush in sequence, and the bearing sleeve is sleeved with a sponge; the two sides of the dust-sealing protecting bush are provided with grooves correspondingly, and the grooves are internally provided with oil seals; the middle of the cylinder body is provided with a piston and a piston rod; the inner side of the cylinder head is provided with a protruded portion in the axial direction, and the piston is internally provided with a spring installation cavity; and a spring arranged in the cylinder body is partially arranged on the protruded portion, and the other part is arranged in the spring installation cavity. A traditional oil seal structure arranged on the bearing sleeve is changed in the manner that the two sides of the dust-sealing protecting bush are symmetrically provided with the oil seals, the original sealing effect is guaranteed while the machining difficulty of the buffer can be greatly lowered, the process manufacturing cost is lowered, and the finished product rate is increased.

Description

technical field [0001] The invention relates to a buffer which is easy to process. Background technique [0002] The buffer is to eliminate the impact, vibration and noise generated in order to increase the production efficiency and speed of operation without affecting the operation performance of industrial equipment, to ensure safety and to optimize the production environment. The buffer of the original structure is complex in structure and large in size, which is not suitable for use in small automation equipment, and the seal of the traditional buffer is to process the oil seal installation groove on the bearing sleeve, and assemble the oil seal and the bearing sleeve to form a sealing structure. Because it is very difficult to process the slot hole on the bearing sleeve, the process is complex and the yield is low. In order to improve the yield of the product, the internal structure of the buffer needs to be improved to meet the same technical requirements. Contents o...
