Abstract

The invention discloses an EGR (Exhaust Gas Recirculation) cooler clamping device, which comprises an upper box and a lower box which are buckled to form a cooler clamping space with an opening at one side, clamping roller mounting and adjusting cavities arranged around the cooling clamping space, and an adjusting roller assembly, wherein the adjusting roller assembly comprises an adjusting screw and a clamping roller, and the adjusting screw also comprises a screw rod and a shaft shoulder; the clamping roller also comprises a cylindrical body, swivels arranged at the two ends of the cylindrical body, and a radial threaded through hole formed in the side of the cylindrical body, and the threaded section of the screw rod is screwed in the radial threaded through hole, so that the rotation movement of the adjusting screw is converted into the movement of the clamping roller. The EGR cooler clamping device has the advantages that the structure is reasonable, the operation is simple and convenient, and the thin wall of an EGR cooler can be clamped by the adjustable adjusting roller, the clamping area is increased, the clamping stability is improved, and the thin wall of the EGR cooler can not be bruised or scratched.

Description

technical field [0001] The invention relates to the field of diesel engine assembly, in particular to an EGR cooler clamping device. Background technique [0002] Diesel engine EGR cooler is a thin-walled special-shaped part. Since the EGR cooler needs to be connected to other parts on its diamond-shaped flange surface and tightened to torque, it usually needs to be clamped with a vise, or vertically penetrated into the clamp. [0003] The EGR cooler is clamped by a vise, which may easily cause the thin wall of the EGR cooler to be crushed or scratched. Contents of the invention [0004] The present invention aims to overcome the defects in the above-mentioned prior art, and provides a clamping device for an EGR cooler with reasonable structure, easy operation, stable clamping, and the ability to avoid crushing or scratching of the thin wall of the EGR cooler. [0005] In order to achieve the above object, the present invention provides a clamping device for an EGR cooler...
