Description

Device for automatically press-fitting EPB calipers and MGU

Technical Field

The utility model belongs to braking calliper assembly automatic assembly field, concretely relates to device of automatic pressure equipment of EPB calliper and MGU.

Background

The Brake caliper assembly is a main part of an automobile Brake part, a mechanical lever mode is adopted in the traditional automobile parking, and along with the change of electronic technology, an Electric Park Brake (EPB) electronic parking system gradually replaces the traditional mechanical lever hydraulic mode. In order to accommodate the electronic parking system, the automobile manufacturer has designed a new brake caliper assembly, i.e., EPB caliper assembly, including EPB calipers and MGUs (electronic parking actuators). The automatic assembly line of the original brake caliper assembly does not need to press the EPB caliper and the MGU of the electronic parking actuator, and in order to meet the market demand, automobile manufacturers gradually upgrade and reform the automatic assembly line of the original brake caliper assembly.

The EPB caliper assembly mainly comprises two parts: EPB calliper and MGU, current EPB calliper assembly mode of assembly generally divide into two parts promptly EPB calliper is fixed and MGU pressure equipment. EPB calliperprincipal parts are for cast moulding, only screw hole terminal surface department on the machined surface, therefore the fixed mode of traditional calliper has still been adopted to current EPB calliper fixed mode, carries out the bolt tightening through the screw hole promptly, and this kind of fixed mode of screwing up mainly divide into manual screwing up and automatic screwing up: manual tightening requires manually tightening the threaded rod with a wrench or using a tightening gun to assist in manually tightening the threaded rod; the automatic screwing adopts one or two screwing guns and related mechanisms to screw the threaded rod, so as to fix the EPB calipers, and the two fixing devices need to process special threaded rods. The threaded rod is a quick-wear part, and in addition, the repeated assembly and disassembly of the EPB calipers can reduce the production efficiency.

The MGU is pressed on the EPB calipers in a manual mode and an automatic mode, and the MGU is manually held by a hand and pressed on the EPB calipers manually; the automatic press-fitting is that the MGU is manually placed on a device, the device automatically presses the MGU onto the EPB calipers, but before the MGU is pressed, a special tool is needed to rotate the MGU spline shaft and the EPB caliper spline hole to the same angle direction, then the MGU is pressed, if the press-fitting fails, the angle of the MGU spline shaft and the EPB caliper spline hole needs to be manually adjusted again, and therefore the press-fitting work is guaranteed to be completed smoothly. In the current automobile industry, the force for pressing the MGU to the EPB calipers is about 100-500N, the labor intensity of manual pressing is high, and the assembly precision is reduced due to the assembly of manual participation, so that the reject ratio of products is improved.
