Description

technical field

[0001] The invention relates to a jig drilling tool, in particular to a jig drilling jig for a liner hole at the bottom of an inclined oil cylinder. Background technique

[0002] In order to quickly and conveniently pick up the goods, the mast needs to be tilted forward; when carrying the goods, in order to prevent the goods from falling, the mast needs to be tilted backward to ensure the stability of the goods. Therefore, the front and rear tilting of the mast is completed by the tilting cylinder, so the tilting cylinder is one of the indispensable components for the operation of the forklift.

[0003] At present, there is no special tooling for drilling the bushing hole of the cylinder bottom of the tilting cylinder, and most of the processing is carried out by ordinary drilling methods. The clamping and positioning are troublesome, time-consuming and laborious, and the work efficiency is low, which cannot meet the needs of batch processing and production. ...
