Heavy truck cab fixture clamping unit structure generally consists of bearing, the clamping element (cylinder), briquetting and positioning blocks. Supports choices are common parts, cylinder is purchased parts. Designers by positioning requirements according to truncate only compact design and positioning blocks can be. Locating and clamping unit versatile, reliable structure, good processing, manufacturing precision easy to ensure easy adjustment and measurement, easy handling and so on. After such a high precision boring unit by installing fixtures on the floor, you can ensure that products on the jig positioning accuracy heavy truck cab, cab assembly to ensure accuracy. This fixture uses 81 locating and clamping units. When the front and rear heavy truck cab Wai Wai were fixtures in the horizontal position, the pieces of equipment to the front and rear Wai Wai assemblies were loaded into the fixture.
