Problems solved by technology

There is also special processing equipment for the valve seat and valve port, but due to its complex structure, difficult adjustment, and can only be used for a certain type of model, the efficiency is low and it is difficult to meet the needs of production, and the special equipment is expensive. At present, most small enterprises use the most primitive repair method: use forming grinding wheel to grind the valve seat and valve port one by one, but the grinding wheel is easy to wear during the grinding process, which affects the flatness of the valve port, and It will lead to the inconsistency of the valve opening angle of each valve. This kind of manual labor is labor-intensive for the operator, and the production efficiency is low, and the effect is also difficult to meet the ideal requirements.
The above-mentioned defects have become the "bottleneck" in the repair of the valve seat of the cylinder head of the diesel engine, so it is necessary to improve

Embodiment Construction

[0032] Attached below Figure 1-16 An embodiment of the present invention is described.

[0033] A device for processing a valve seat valve port of a cylinder head of a diesel engine has a core shaft I2, a shaft sleeve 3, a connecting rod 6, a core shaft II20, a movable support sleeve 8, a transmission rod 11, a support plate 17 and a connecting shaft 18. The core The shaft I2 is sleeved in the valve stem hole 26 of the cylinder head 5 and one side of the shaft shoulder 27 on the core shaft I2 is pressed against the inner wall of the cylinder head 5, and the other side of the shaft shoulder 27 is pressed against the sliding bearing 4 and the core shaft I2. The shaft sleeve 3, the other end of the mandrel I2 is locked with the nut 1; the end of the shaft sleeve 3 is formed with a connecting lug 25 and a connecting column 24 at 90 degrees. One end of the connecting rod 6 is fixedly connected with the connecting column 24, and the mandrel One end of II20 is fixedly connected with t...

Abstract

The invention provides a device for machining a valve seat valve port of a cylinder head of a diesel engine. A central spindle I is sleeved and mounted in a valve rod hole of the cylinder head and propped against an inner side wall of the cylinder head, the other side of a spindle shoulder is propped against a spindle sleeve matched with the central spindle through a sliding bearing, and the other end of the central spindle I is locked by a nut; a connecting lug and a connecting post are machined at ends of the spindle sleeve in a 90-degree manner, one end of a connecting rod is fixedly connected with the connecting post, one end of a central spindle II is fixedly connected with the connecting lug, a spring is fixed at the other end of the central spindle II and sleeved in an inner hole of a movable support plate, both the other end of the connecting rod and the other end of the central spindle II are fixedly and integrally connected with the movable support plate, a pulley limited in a chute of a drive rod is arranged at the other end of the movable support plate, the drive rod is fixed on a support plate fixedly connected with one end of a connecting shaft, the other end of the connecting shaft is inserted in a shaft hole of a boring bar main shaft, a cutter clamping plate is arranged on one side of the movable support plate, a cutter is fixed on the cutter clamping plate through a bolt and aligned to a conical valve port. The device is good in generality and high in working efficiency.

Description

Technical field [0001] The invention belongs to the technical field of mechanical processing, and particularly relates to a device for processing a valve seat of a cylinder head of a diesel engine. Background technique [0002] In the working process of the cylinder head valve seat of a diesel engine, the valve stem and the valve seat produce thousands of opening and closing actions, and the valve port is directly impacted by the valve stem during the working process, resulting in different degrees of wear and corrosion of the valve port. Each repair cycle of a diesel engine needs to process and repair the valve stem and valve seat valve port to restore the complete working performance of the diesel engine. Due to its simple structure, the valve stem can be processed and repaired with a lathe or grinder after disassembly. However, the cylinder head has an irregular shape due to its complex structure. Each cylinder head has 4 valve seats distributed in different positions. Due to...
