Problems solved by technology
There are four problems in this positioning method: First, due to the clearance fit, the axis of the workpiece to be assembled hole is not necessarily coaxial with the positioning mandrel of the fixture; secondly, due to the center of gravity of the workpiece, the lower end surface of the assembled hole cannot be aligned with the The support surface of the fixture is completely fitted, which will inevitably cause the axis of the workpiece assembly hole to be non-perpendicular to the support surface of the fixture; again, the size of the positioning mandrel of the fixture cannot be used in common with the assembly hole size of the workpiece. The size of the positioning mandrel needs to be replaced; finally, the control size of the indenter cannot be adjusted, and the corresponding indenter needs to be replaced for different assembly control sizes

The invention discloses steering knuckle press fitting equipment. The steering knuckle press fitting equipment comprises a rack. A lower fixing plate is mounted on the lower portion of the rack. A hollow fixing sleeve is arranged on the lower fixing plate. A support plate is fixed to the top end of the fixing sleeve. A hollow sliding sleeve is formed in a gap in the fixing sleeve. A chuck is connected to the upper end of the sliding sleeve, the lower end of the sliding sleeve is connected with a first spring, and a cylinder is fixed in the sliding sleeve. The output end of the cylinder is upwards fixedly connected with a tip cone. An elastic clamping device is arranged in the chuck. A conical surface matched with the tip cone is arranged on the lower portion of the elastic clamping device.The tip cone moves upwards to extrude the conical surface. The elastic clamping device can clamp a steering knuckle. A first servo electric cylinder is fixed to the upper portion of the rack. The output end of the first servo electric cylinder is downwards connected with a pressing head assembly through a pressure sensor. The pressing head assembly can press a bushing into the steering knuckle under the driving of the first servo electric cylinder. The positioning precision is high, and the universality is high.
Description
technical field [0001] The invention relates to the field of press-fitting equipment, in particular to a steering knuckle press-fitting equipment. Background technique [0002] The aluminum alloy rear steering knuckle usually needs to be used with a rubber bushing during use. The traditional assembly method of the rubber bushing and the steering knuckle is to use the clearance fit between the assembled hole of the steering knuckle and the floating mandrel of the fixture to realize the radial direction of the workpiece. Positioning, use the lower end surface of the assembled hole to contact the supporting surface of the fixture to realize the axial positioning of the workpiece; then use a special pressure head to press the bushing into the assembled hole of the steering knuckle. There are four problems in this positioning method: First, due to the clearance fit, the axis of the workpiece to be assembled hole is not necessarily coaxial with the positioning mandrel of the fixtu...
