High-precision cylinder cover camshaft bore transfer

Abstract

The invention discloses a high-precision cylinder cover camshaft bore transfer. The high-precision cylinder cover camshaft bore transfer comprises a machine frame, a sliding seat and a base are arranged on the machine frame, a boring cutter conveying and transferring device is arranged on the sliding seat, a cylinder cover conveying and compressing device and a cutting fluid spraying and lubricating device are arranged on the base, a bearing is replaced with a copper sleeve, a lubricating groove and a lubricating hole are formed in the copper sleeve, and a high-pressure cutting fluid is conveyed into the lubricating groove from the lubricating hole, so that the cutting fluid is always in the lubricating groove in the inner wall of the copper sleeve, the excellent lubricating function of the copper sleeve and a boring cutter matched with the copper sleeve is achieved, the wear on the copper sleeve and the boring cutter is reduced accordingly, and the processing precision is high; and aspraying fluid conveying hole conveys the low-pressure large-flow cutting fluid through the spraying head in a spraying seat to conduct exterior spraying on the processing positions of the boring cutter, a blade and the camshaft bore of a cylinder cover, the fact that aluminum scrape after processing can be timely washed away is ensured, the processing positions can be effectively cooled, and thefact that the processing precision is influenced due to the overheating expansion of the processing positions is avoided.

Description

technical field [0001] The invention relates to a high-precision cylinder head camshaft hole turning machine, which belongs to the field of cylinder head processing equipment. Background technique [0002] The camshaft is a part of the piston engine. Its function is to control the opening and closing of the valve. There is a camshaft hole in the cylinder head of the engine, and the camshaft hole plays the role of matching the camshaft. The coaxiality and precision of camshaft hole processing are very high. The disadvantages of the existing cylinder head camshaft hole rotary machine are: 1. A bearing seat is arranged on the base, and a bearing is arranged in the bearing seat. The boring tool passes through the bearing, and the boring tool rotates with the bearing during work. Due to the bearing structure, There is no lubricating fluid inside, and only the lubricating fluid can be sprayed outside the bearing. The lubrication effect is poor. After the boring tool rotates for a...

Problems solved by technology

The disadvantages of the existing cylinder head camshaft hole rotary machine are: 1. A bearing seat is arranged on the base, and a bearing is arranged in the bearing seat. The boring tool passes through the bearing, and the boring tool rotates with the bearing during work. Due to the bearing structure, There is no lubricating fluid inside, and only the lubricating fluid can be sprayed outside the bearing. The lubrication effect is poor. After the boring tool rotates for a long time, both the boring tool and the bearing are prone to heat and wear, which will affect the machining accuracy. Bearings increase the replacement cost of parts; 2. Workers directly put the cylinder head on the base of the processing position. Since the base is surrounded by chassis, brackets and other structures, the cylinder head is placed directly, which is inconvenient to place and improves The labor intensity of the workers reduces the processing efficiency; 3. There is no detection device after the cylinder head is put in place, and the workers can only observe whether it is in place. scrapped
