Cylinder block clamping seat

Abstract

The invention discloses an air cylinder clamping seat, which comprises a bottom beam, side columns, leg press blocks, an upper beam, a transverse beam and a middle column, wherein the bottom beam is formed by parallelly arranging channel steel with downward openings, the side columns are respectively formed by parallelly arranging channel steel with inward openings, and are respectively and vertically arranged at the two ends of the bottom beam in an opening-opposite manner, the outer side of each leg press block is provided with a U-shaped mounting groove, and is arranged at the outer side of the bottom end of each side column through a first bolt, the periphery of the contact part is firmly welded, the upper beam is formed by processing two round bars, the two ends of the upper beam are respectively arranged at the top ends of the side columns through second bolts, the periphery of the contact part is firmly welded, the transverse beam is formed by processing bars, is parallelly and transversely arranged between the upper beams, and is arranged on the upper beam via bolts, the lower end of the middle column is fixedly arranged on the bottom beam, and the upper end of the middle column is used for supporting the channel steel at the middle of the upper beam. The air cylinder clamping seat is made of bars and channel steel, so the weight is light, and the tensile strength is high.

Description

technical field [0001] The invention relates to the field of engines, in particular to a cylinder block clamping seat. Background technique [0002] At present, in the production of the cylinder block, the semi-finishing top surface process is processed in the vertical machining center, and the pin hole and the bottom surface of the cylinder block are positioned at the bottom surface. The positioning fixture with positioning pins and the clamping seat for clamping the workpiece are designed separately, that is, both the positioning fixture and the clamping seat are directly installed on the machine slide table. The clamps for clamping the cylinder block are installed on the clamping seat by bolts. [0003] But the clamping seat of the cylinder block is cast by cast iron, the tensile strength is low, it is subjected to a large tensile stress when clamping, and the weak part has no reinforced structure, so it often fails due to tensile cracking. In addition, the cast iron cl...

Problems solved by technology

[0003] However, the clamping seat of the cylinder block is made of cast iron, which has low tensile strength and is subjected to a large tensile stress during clamping, and the weak part has no reinforced structure, so it often cracks and fails

In addition, the cast iron clamping seat needs to be made of wood, and the machining needs a large planer and milling machine. The manufacturing cycle is long. Once the clamping seat fails and is damaged, it will take a lot of time to repair or remanufacture, which will seriously affect the production.

[0004] In addition, the fixture seat and the fixture are connected by threaded blind holes. When manufacturing the fixture seat, the requirements for the position of the threaded blind holes are high, and the processing technology is complicated.
