Problems solved by technology

The process is cumbersome, with a large workload and low efficiency. Due to the large number of disassembled parts, the bolts used need to be re-sealed on multiple sealing surfaces due to repeated use and repeated force, which will cause secondary damage to the parts. Risk of secondary damage and oil spills
[0003] At present, there is no device that can lock the engine timing system, so that the rocker-hydraulic tappet assembly can be replaced or repaired without dismantling the timing system.

Embodiment Construction

[0015] Below in conjunction with accompanying drawing, the present invention will be further described:

[0016] like figure 1 As shown, a timing system locking device includes a support plate 1, on which there are two symmetrically distributed adjusting bolt guide grooves 12, 13, through which the adjusting bolt guide grooves pass through the adjusting bolts 7, 9 to A circular arc groove 2 on the intake side and an arc groove 6 on the exhaust side are respectively connected to the lower part of the support plate. Since the main body of the timing system locking device is made of 45# steel, in order to ensure that the timing system of the engine is not worn during locking, an air intake side arc groove soft pad is installed on the inner side of the intake side arc groove 2 4. An exhaust-side circular-arc groove cushion 11 is fitted inside the exhaust-side circular-arc groove 6 .

[0017] The arc groove 2 on the intake side and the cushion 4 on the intake side, the arc groo...

Abstract

A locking device for a timing system comprises a supporting plate in which two symmetrically-distributed adjusting bolt guide grooves of a through hole structure are formed; two adjusting bolts penetrate one corresponding adjusting bolt guide groove respectively to connect an air exhaust side arc-shaped groove and an air inlet side arc-shaped groove under the supporting plate respectively; the inside of the air inlet side arc-shaped groove is provided with an air inlet side arc-shaped groove soft cushion in a matching mode, and an air exhaust side arc-shaped groove soft cushion is arranged inside the air exhaust side arc-shaped groove in a matching mode; a fastening bolt is arranged on the lower portion of the outside of the air inlet side arc-shaped groove, and a fastening bolt is arranged on the lower portion of the outside of the air exhaust side arc-shaped groove.

Description

technical field [0001] The invention belongs to engine component maintenance tooling, in particular to a device for locking a timing system when maintaining an engine. Background technique [0002] In the engine after-sales maintenance, when repairing or replacing the rocker arm-hydraulic tappet assembly, follow the conventional maintenance process, such as image 3 As shown, the engine that needs to be replaced with the rocker arm-hydraulic tappet assembly needs to be dropped from the vehicle first, and then the engine is fixed, and the peripheral parts of the engine cylinder head cover, cylinder head cover, front-end wheel train, front cover, and timing system are disassembled , Camshaft cover, take out the intake and exhaust camshafts of the engine, then replace the rocker arm assembly and hydraulic tappet, and finally restore the engine one by one according to the process requirements, including restoring the engine camshaft cover, engine front cover, engine When the cyl...
