Problems solved by technology

After actual observation and verification at the production site, it was found that during the use of the currently used cylinder head bolt tightening tool, due to the circumferential tightening force of the tightening shaft of the tightening machine, a strong circumferential force is generated between the cylinder head bolt tool and the cylinder head bolt hexagonal head Extruded, it is easy to produce some fine iron filings from the cutting edge of the bolt head, which adheres to the head bolt head, polluting the cleanliness of the head bolt head

Abstract

The invention discloses a cylinder cap bolt tightening tool capable of sucking iron scraps. The cylinder cap bolt tightening tool is used for being installed on a tightening shaft of a tightening machine and comprises a cylindrical body and a magnetic ring. The diameter of the upper end head of the cylindrical body is larger than the diameter of the lower end head of the cylindrical body. The lower end head and the upper end head are connected in a gradually-changing manner. A square counter bore matched with the tightening shaft is formed in the upper end head, and an inner hexagonal counter bore matched with a cylinder cap bolt hexagon head is formed in the lower end head. The magnetic ring is arranged on the outer wall of the lower end head in a sleeving manner. According to the tool, cleanliness of the head of a cylinder cap bolt can be ensured.

Description

technical field [0001] The invention relates to the field of tools, in particular to a cylinder head bolt tightening tool capable of absorbing iron filings. Background technique [0002] As we all know, the head of the engine cylinder head bolts is in contact with the engine oil, so the cleanliness of the cylinder head bolts and the bolt heads is relatively high, and no foreign matter, iron filings, etc. After the brushing of the engine oil, it is washed into the engine oil, and then transported to each oil passage through the oil pump, especially to the connecting rod bush, the main bearing bush, and the cooling spray hook, which will produce the connecting rod bush, the main bearing bush, and the piston. Serious quality problems such as cylinder pulling. After actual observation and verification on the production site, it was found that during the use of the currently used cylinder head bolt tightening tool, due to the circumferential tightening force of the tightening sh...
