Automatic steering gear clearance adjusting machine

Technical Field

The invention relates to an automatic steering gear clearance adjusting machine, which effectively solves the problem of automatic steering gear clearance adjustment. Belongs to the field of ultra-precision machining equipment.

Background

The steering gear clearance adjusting machine produced in China at present adopts a manual adjusting mode, adopts manual feeding and discharging and manual clearance adjustment, and cannot meet the requirement of automatic production. Based on the above, we developed an automatic gap adjuster for a steering gear, so that the adjusted gap of the steering gear can be fully automated in the gap adjustment process on the basis of meeting the requirements, and the requirements of factory automation production can be met. Fills the domestic blank.

Disclosure of Invention

The invention provides an automatic steering gear clearance adjusting machine. The equipment adopts a full-automatic working mode, and automatically detects and adjusts the meshing clearance of the steering gear and measures the meshing clearance during the full-stroke movement of the rack. When the clearance is measured, the workpiece is clamped and measured into a whole through a precise mechanical structure, and the influence of the outside on a measurement result is reduced when the clearance is measured. The axis translation connection between the electric tightening machine and the adjusting mechanism is realized through the high-precision rotary connecting body. And the servo motor is used for driving the automatic gap adjusting mechanism to move transversely, so that the requirements of workpieces with different input shaft hole positions can be met.

The technical scheme adopted by the invention is as follows: the automatic moving-in and moving-out mechanism 1 is connected with the rack 4 through a bolt group; the PLC electrical control box 2 is connected with the touch screen control panel 5 through a data bus; the automatic gap adjusting mechanism is connected with the rack 4 through a bolt group; the rack moving driving mechanism 6 is connected with the rack 4 through a bolt; the automatic gap adjusting mechanism 3 is respectively connected with the touch screen control panel 5 and the PLC electrical control box 2 through data lines;

in the aspect of electrical control, a PLC and a touch screen are adopted for control, and a servo motor and an air cylinder are adopted as power sources and are responsible for all operation instructions and implementation of equipment.

The gain effect of the invention is as follows:

structurally: the automatic feeding and discharging mechanism is adopted in the equipment, so that online production of the equipment is met, and labor is saved. And the meshing clearance can be automatically measured, the pressing block plug can be adjusted, the beat is saved, and the workload of workers is reduced. The touch screen is used as a manual interface, so that the operation is simplified, and meanwhile, the setting of operation data is more flexible, and the measurement and adjustment requirements of different workpieces can be met. The equipment frame adopts the welded structure of steel sheet and square steel, has guaranteed sufficient rigidity and intensity, can guarantee the stability in the measurement process, and the protection of frame top adoption section bar and organic glass is both safe and pleasing to the eye. The structure integrating workpiece clamping and measurement is adopted, so that the influence of the outside on the measurement structure during gap measurement can be effectively reduced.

In terms of control: by applying the built-in clearance measuring sensor, the meshing clearance can be accurately and quickly measured, and the measuring precision is ensured; the servo motor is used as a power source for driving the rack, so that the requirement of performing full-stroke detection on workpieces with different lengths can be met.
