Problems solved by technology

[0002] At present, the oil channel of the oil pan of the vehicle engine is generally sealed by thread plugging and sealant. This sealing method requires the oil channel of the oil pan to have a threaded bottom hole, which makes the processing of the oil pan more complicated, and the tightening of the thread plug The torque control is relatively strict, and the sealing effect is not very good, and oil leakage and oil leakage often occur

Embodiment Construction

[0012] A kind of blockage for sealing the oil channel of the oil pan, the blockage is a blind rivet 10, the blind rivet 10 is composed of two parts, one part is a hardened carbon steel rivet core 12, and the other part is a fully annealed aluminum cap body 11, the radial dimension of the cap body 11 is smaller than and close to the size of the oil passage hole 21, the dimensional tolerance of the oil passage hole 21 is 0-1.5mm, and the center position of the cap body 11 is provided for the rod body 122 of the rivet core 12 to pass through. through the through hole 111, the direction of the through hole 111 is consistent with the rod length direction of the rod body 122, and the diameter of the rod body 122 in the through hole 111 changes from large to small, and the diameter change should be completed in a shorter length range to ensure reliable realization break, and the overall length of the part is correct. The diameter reduction part is provided with a fracture part 123 al...

Abstract

The present invention relates to a seal oil bottom case oil passage jam, wherein the jam is a self-plugging rivet composed by clinch bolt core and hat. A through hole is provided on the central position of the hat for rod of the clinch bolt core passes through and the trend of the through hole consistent with rod body direction. A fracture part is set along circumferential direction on the rod inside the through hole; radial dimension of the head of the clinch bolt core bigger than diameter of aperture of the through hole and smaller than radial dimension of the hat. The present invention also discloses a bottom case oil passage jam method. A clinch bolt is stricken into the oil passage hole and then outer pulled to make interference fit between the transformed clinch bolt and the oil passage hole thereby be sealed.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a blockage of an oil channel of a sealed oil sump and a blockage method thereof. Background technique [0002] At present, the oil channel of the oil pan of the vehicle engine is generally sealed by thread plugging and sealant. This sealing method requires the oil channel of the oil pan to have a threaded bottom hole, which makes the processing of the oil pan more complicated, and the tightening of the thread plug The torque control is relatively strict, and the sealing effect is not very good, and oil leakage and oil leakage often occur. Contents of the invention [0003] The primary purpose of the present invention is to provide a sealing oil pan oil channel blockage that can eliminate the oil leakage phenomenon of the oil pan oil channel and has strong sealing performance. [0004] In order to achieve the above purpose, the present invention provides a blockage for sealing the oi...
