Bushing press-fitting device for exhaust gas recirculation valve assembly

Abstract

The invention discloses an exhaust gas recirculation valve assembly bushing press-fitting device and belongs to the technical field of bushing press-fitting. Symmetrical supporting blocks are fixedly connected to the surface of a bottom plate, sliding grooves are formed in the side faces of the supporting blocks, sliding blocks are slidably connected to the inner walls of the sliding grooves, clamping blocks are fixedly connected to the surfaces of the sliding blocks, and fastening rods are connected to the side faces of the clamping blocks in a sleeving mode; according to the exhaust gas recirculation valve assembly lining press-fitting device, through the arrangement of the lead screw and the extrusion rod, under the action of threads, the extrusion plate and the extrusion block can be stably pushed downwards to move downwards, then the lining is driven to be pressed into a recirculation valve assembly, and therefore the lining is pressed into the recirculation valve assembly, and the service life of the exhaust gas recirculation valve assembly is prolonged. The mounting stability and accuracy of the bushing are improved, impact on the recirculation valve assembly is avoided, and the clamping blocks with adjustable positions and the replaceable extrusion rods are arranged, so that the recirculation valve assemblies with different sizes can be conveniently fixed, and the bushings with different sizes can be conveniently pressed.

Description

technical field [0001] The invention relates to the technical field of liner press-fitting, and more specifically, to a liner press-fitting device for an exhaust gas recirculation valve assembly. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, adjust and control the parameters (temperature, pressure and flow) of the conveying medium. [0003] At present, there are many types of valves, including recirculation valves. During the assembly process of recirculation valves, a press-fitting device is required to install the bushing, but the general bushing is installed on the bushing through the impact force during the installation process. , such as the announcement number CN214292909U discloses a lower press-fit assembly and press-fit tooling for preventing leakage and shrinkage bushing. During the assembly process, not only the installation position of the bush is not accurate enough, but also the impact fo...

Problems solved by technology

[0003] At present, there are many types of valves, including recirculation valves. During the assembly process of recirculation valves, a press-fitting device is required to install the bushing, but the general bushing is installed on the bushing through the impact force during the installation process. , such as the announcement number CN214292909U discloses a lower press-fit assembly and press-fit tooling for preventing leakage and shrinkage bushing. During the assembly process, not only the installation position of the bush is not accurate enough, but also the impact force will cause impact on the valve body. , and it is impossible to install bushes and valve body assemblies of different sizes. Therefore, we have designed a bushing press-fitting device for exhaust gas recirculation valve assembly to solve the above problems
