The invention discloses a processing fixture for a disc brake caliper, which comprises a base and an upper plate, and a fixture mechanism fixed between the base and the upper plate; the fixture mechanism is assembled from an upper fixture component and a lower fixture component; The upper clamp assembly and the lower clamp assembly are respectively separated by the middle plate to form four clamp units with the same structure; each clamp unit is equipped with an oil cylinder clamping mechanism; the oil cylinder clamping mechanism is connected to the oil circuit; the present invention The processing fixture of the disc brake caliper adopts a four-position structure, so that the air disc brake caliper can process four workpieces at a time on the exchange pallet of the horizontal machining center and complete the processing in one order, which improves the production. efficiency.
Description
technical field [0001] The invention relates to a processing fixture, in particular to a processing fixture for a disc brake caliper body, and belongs to the technical field of brake processing equipment. Background technique [0002] Such as figure 1 The air disc brake caliper shown here is made of QT550-5 high-strength ductile iron casting. It has a complex structure, many processing surfaces, and requires high processing precision; however, in the past similar fixture designs, hydraulic and manual clamps were mostly used. The clamping method has poor machining accuracy and extremely low efficiency. In order to improve the machining accuracy and reduce the positioning error of multi-sequence machining, the fewer machining processes are required, the better. At the same time, in order to improve the machining efficiency of the workpiece and reduce the number of tool changes, the fixture requires as many workpieces as possible, and the use of hydraulic pressure Features, r...
