Technical Field
[0001] The utility model relates to the technical field of steering systems, in particular to a tooling for fixing a steering machine of an automobile. Background Art
[0002] The automotive electric power steering gear consists of a sensor unit, a motor unit, a servo unit, a housing, a rack, an adjustment nut, a dust cover, a tie rod and an outer ball head. The upper end of the sensor unit is connected to the steering system and the steering wheel, and the outer ball head is indirectly connected to the wheel. The rotation of the steering wheel will be transmitted to the rotation of the steering gear, and the rotation of the steering gear will drive the rack to move horizontally, and the drive gear will mesh with the rack to provide electric power. Due to the meshing movement of the gear and rack, the meshing clearance and meshing quality of the gear and rack will directly affect the performance of the steering gear. The clamping mechanism can keep the steering gear and the drive gear close to the rack. The adjusting nut is screwed into the housing to tighten the clamping mechanism, and the threads of the adjusting nut and the housing are riveted to prevent loosening. After riveting, the loosening torque needs to be tested. After adjusting the nut riveting point, the deformation of the pressure block hole is required to be small. Therefore, there are high requirements on the direction of the riveting point force and the supporting surface of the steering gear during riveting. When the adjusting nut is loosened for torque test, the steering gear needs to be fixed. After the steering gear is fixed, it is best to complete the riveting point and anti-loosening torque test of the adjusting nut at the same time.
[0003] Some electric power steering gears use two adjustment nuts that are not arranged on the same side, and the back of the adjustment nuts have different shapes. First, fix the steering gear so that the direction of adjustment nut one is vertically upward, and the back of adjustment nut one is the main force-bearing surface. Perform riveting point and anti-loosening torque tests on adjustment nut one. Then reverse and fix the steering gear so that the direction of adjustment nut two is vertically upward, and the back of adjustment nut two is the main force-bearing surface. Perform riveting point and anti-loosening torque tests on adjustment nut two.
[0004] For steering gears with two adjusting nuts not arranged on the same side, the positions of the adjusting nuts and the shapes of the back of the adjusting nuts are different due to the different housings. Some steering gears have two adjusting nuts arranged on the same side, and the shapes of the back of the adjusting nuts are also different; some steering gears use a single adjusting nut; different types of steering gears have different numbers of adjusting nuts and the shapes of the back of the adjusting nuts. In the prototype development stage, there are many product types and a tight development cycle. Special equipment is used to fix the automobile steering gear in a specified position. The equipment manufacturing cycle is long, the cost is high, the versatility of multiple products is poor, and the cost of tooling changeover is high.
[0005] Therefore, a set of clamps for fixing the automobile steering gear at a specified position is provided, which has low cost and strong versatility and meets the requirement of fixing the steering gear at a specified position during the assembly process of the automobile steering gear adjusting nut.
