The upper end end face of positioning seat is connected with workpiece, and endoporus and the pull bar of positioning seat are slidably matched, between the positioning seat and connect base
Linked together by fastener；Connect base is enclosed on the upper end of pedestal, and is fixedly connected by key with pedestal.Therefore, originally
Positioning seat, connect base can be mounted and dismounted in installation and removal, greatly reduce workman and move work by invention respectively
The weight of part, its operation is more convenient.
3. maintenance cost is low：
Because the top half that the seat that is located by connecting of the present invention is connected with workpiece is easily worn, therefore, the present invention connects positioning
Joint chair is designed as Split type structure, i.e. the seat that is located by connecting including positioning seat, connect base, when positioning seat is worn it is serious when, only
Need to change the positioning seat, changed together without the whole seat that is located by connecting, so as to greatly reduce maintenance cost.
4. structure is reliable：
Because the bottom of the pressing plate of the present invention is provided with positioning step I, the upper end end face for the seat that is located by connecting is provided with positioning step II,
The described spring piece that rises is socketed between the positioning step I and positioning step II.By the positioning step I and positioning step II,
Can make spring rise piece installation positioning it is reliable.
Stopper slot is additionally provided with piece further, since spring rises, spacer pin is installed on be located by connecting seat or positioning seat, should
Spacer pin is engaged with stopper slot to ensure that the spring piece that rises can not skid revolution, and therefore, structure of the invention is practical reliable.
5. machining accuracy can be improved：
Because the present invention can eliminate the gap between positioning tool and back-plate, the machining accuracy of brake can be greatly improved,
It is effectively guaranteed the bounce precision of brake.
Below, technical characteristic in conjunction with the accompanying drawings and embodiments to the positioning and clamping mechanism of the brake Excircle machining of the present invention
