Servo indexing turnover drilling and milling clamp for wheel machining and method for vehicle drilling and milling through same

Abstract

The invention discloses a servo indexing turnover drilling and milling clamp for wheel machining and a method for vehicle drilling and milling through the same. The clamp comprises a platform mechanism, a servo turnover mechanism, a center rotary mechanism and a lateral pressing mechanism, wherein the servo turnover mechanism, the center rotary mechanism and the lateral pressing mechanism are arranged on the platform mechanism and are in signal communication with a machining center control system to achieve instruction control. The turnover mechanism is driven by a servo motor to achieve 360-degree high-precision turnover of wheels, the center rotary mechanism is driven by the servo motor to achieve 360-degree high-precision rotation of the wheels, and the side pressing mechanism is used for achieving lateral fixation of the wheels and the like and can be used for machining 14-22-inch hubs. The hubs can turn over along with the clamp, rotary linkage of the wheels around the center canbe achieved, and the clamp is particularly suitable for drilling and milling of different surfaces of special hubs, for example, bolt holes, valve holes and outer rim parts are drilled and milled after one-time clamping and positioning of the hubs; the clamp plays an active role in achieving machining of the wheels of special structures, reducing the cost and improving the efficiency.

Description

technical field [0001] The invention relates to the field of drilling and milling processing of aluminum alloy wheels, in particular to a fixture and a drill for drilling and milling processing of bolt holes, valve holes, and wheel rims in the circumferential direction (tread) of multiple places in one clamping and positioning of aluminum alloy wheels. milling method. Background technique [0002] It is known that when an aluminum alloy wheel is processed on a conventional three-axis machining center with the aid of a conventional flip fixture, the processing of valve holes, bolt holes, and front decorative nail holes can be completed at one time. If the turning fixture is driven by hydraulic pressure, and the fixed angle block controls the turning angle, only one fixed angle can be turned each time; if the turning is driven by a servo motor, the tooling can only turn at any angle around the X-axis of the machine tool. If drilling and milling is required on the remaining su...

Problems solved by technology

If drilling and milling is required on the remaining surface of the aluminum alloy wheel circumference, the existing fixtures cannot complete the one-time clamping process of this type of product, and multiple clamping processes will lead to a decrease in product processing accuracy, efficiency and increase in product processing costs

[0003] Due to the variety of aluminum alloy wheels tends to be diversified and customers have special requirements for product structure and shape, the current conventional machining centers cannot meet the diversified processing of wheels. If the four-axis and five-axis machining centers are used, the processing cost is high, so special design is made for the fixture. It is very necessary to make up for the deficiency in the conventional processing of wheels
