Clamp for quickly changing inner support of cylinder jacket

Abstract

The invention discloses a clamp for quickly changing an inner support of a cylinder jacket. The clamp comprises a cylindrical body, wherein an axial passage is formed in the centre of the cylindrical body; a push-and-pull rod is arranged in the body; an end cover is arranged on the outer side of the push-and-pull rod; the inner side of the push-and-pull rod is connected with a piston rod of a hydraulic oil cylinder through a connecting sleeve; hollow vulcanized rubber rings and distance rings are sleeved on the outer surface of the body; one distance ring is arranged between every two adjacent hollow vulcanized rubber rings; a notch is formed on the inner side of each hollow vulcanized rubber ring; the hollow vulcanized rubber ring at the innermost end is tightly adhered to a step of the body; a push ring is arranged on the outer side of the hollow vulcanized rubber ring at the outermost end; the outer side of the push ring is tightly adhered to the end cover; spring random sleeves are sleeved on the outer surfaces of the hollow vulcanized rubber rings and the distance rings; and air cylinder sleeves are sleeved on the outer surfaces of the spring random sleeves. By the clamp, workpieces are quickly and conveniently assembled and disassembled; and when the line of production is changed, a tool can be quickly changed, the production auxiliary time can be shortened and the production efficiency can be improved so as to reduce the production cost.

Description

technical field [0001] The invention relates to a quick-change fixture for an inner support of a cylinder liner. Background technique [0002] At present, the machining of cylinder liners generally adopts single-cone inner support fixtures, double-cone inner support fixtures, and plastic fixtures. When the above three fixtures are changed to production, it takes a long time to replace the tooling, which seriously affects production efficiency and is not suitable for small batches. Variety production line needs. The object of the present invention is to overcome the above-mentioned shortcomings of the prior art, and to provide a cylinder liner clamp that can be quickly replaced when changing production. Contents of the invention [0003] The object of the present invention is to provide a quick-change fixture for cylinder liner inner supports, which is fast and convenient for loading and unloading workpieces, can realize quick tooling replacement when changing production, ...
