Engine hydraulic tappet installation tool

Abstract

The invention provides an engine hydraulic tappet installation tool and belongs to the technical field of engine assembly assisting equipment. According to the engine hydraulic tappet installation tool, a tool body (1) is provided with multiple clamping blocks (2) arranged at intervals, the inner wall of a sleeve portion (3) at the lower end of each clamping block (2) is provided with multiple concave holes (4), and a spring (5) and a clamping pin (6) are sequentially arranged in each concave hole (4). When a hydraulic tappet (7) is sleeved with each sleeve portion (3), the clamping pin (6) ineach concave hole (4) of the inner wall of the sleeve portion (3) is arranged to be of the structure capable of being clamped into a groove (8) in the side face of the hydraulic tappet (7). By meansof the engine hydraulic tappet installation tool, batch assembly of the engine hydraulic tappets can be conveniently and rapidly completed, engine hydraulic tappet assembling efficiency is effectivelyimproved, the engine production line rhythm is met, engine yield restriction is eliminated, and safety of operators is protected.

Description

technical field [0001] The invention belongs to the technical field of engine assembly auxiliary equipment, and more specifically relates to an engine hydraulic tappet installation tool. Background technique [0002] The air distribution system of the engine is installed with valve tappets. In order to ensure the reliable operation of the engine, the adjustment of the valve clearance is complicated and cumbersome. The installation method of the column is too simple, and the rhythm caused by a single installation is at the bottleneck, and the fit gap is small, while the internal structure of the cylinder head is complex, and the corners of the cylinder head will occasionally cause scratches to the hands of the operator. Most of the installation methods for hydraulic tappets in the existing assembly line are installed manually, which has the following disadvantages: a.

Problems solved by technology

[0002] The air distribution system of the engine is installed with valve tappets. In order to ensure the reliable operation of the engine, the adjustment of the valve clearance is complicated and cumbersome. The installation method of the column is too simple, and the rhythm caused by a single installation is at the bottleneck, and the matching gap is small, while the internal structure of the cylinder head is complicated, and the corners of the cylinder head will occasionally cause scratches to the hands of the operator

Most of the installation methods for hydraulic tappets in the existing assembly line are installed manually, which has the following disadvantages: a. According to the requirements of various companies, special gloves are allowed to be worn on the inner cavity of the engine, and the use of gloves is strictly prohibited

However, after the cylinder head is cast and formed, it is processed through various processes and becomes the final product when it is installed on the assembly line. Due to the complex structure of the cylinder head itself, there are too many corners at the installation hole of the camshaft cover, and this place is too close to the hydraulic tappet hole. , During the installation process for operators without gloves, there will be a great risk of scratching hands; b. The cylinder head is divided into intake valve and exhaust valve, and the valve is also divided into intake valve and exhaust valve. Each valve is equipped with a hydraulic tappet. For a 4-cylinder engine, each cylinder head needs to have 16 hydraulic tappets installed. If it takes 10 seconds to install 1 hydraulic tappet, it takes 160 seconds to install 16 tappets. Therefore, The installation of the class cannot meet the production demand in terms of beats, causing a production bottleneck on the assembly line and restricting the production output
