Locking tool for processing impeller of hydrodynamic retarder of heavily loaded truck

Abstract

The invention relates to a locking tool for processing an impeller of a hydrodynamic retarder of a heavily loaded truck. The locking tool comprises a tightening cover and a locking cover, wherein the tightening cover is provided with a groove for mounting a workpiece and a through hole where a spiral broach passes through; the tightening cover comprises a cylindrical tightening cover main body, a plurality of conically distributed tightening blocks are arranged on one side of the mounting piece of the tightening cover, a gap is reserved between two adjacent tightening blocks and the gap extends to a position on one side, far from the workpiece in the middle part of the tightening cover main body; the locking cover is mounted on the outer side of the tightening cover, and meanwhile, conical tightening holes corresponding to the tightening blocks are formed in the end portion of the locking cover, and the apertures of the tightening holes are smaller than the apertures of cones formed by the tightening blocks in rolling out states but greater than or equal to the apertures of cones formed by the tightening blocks in tightening states. The locking tool provided by the invention has the advantage that the locking tool can clamp the workpiece without any direct connecting pieces, and is convenient to mount and detach.

Description

technical field [0001] The invention relates to the field of auto parts processing, in particular to a locking tool for processing the impeller of a hydraulic retarder of a truck. Background technique [0002] The hydraulic retarder is also called the hydraulic retarding device. Cars use pneumatic or hydraulic brakes when going down long and steep slopes. Although they can receive good braking effects, for heavy vehicles with a large load of more than nine meters, the effect of using pneumatic or hydraulic brakes is limited, and The brake assembly is very prone to lock failure. Therefore, the state stipulates that a passenger car over nine meters and a truck over twelve meters must be equipped with a retarder device. The stator of the hydraulic retarder is also the retarder housing, which is connected with the rear end of the transmission or the vehicle frame, and the rotor is connected with the transmission shaft through a hollow shaft, and blades are cast on the rotor an...
