Embodiment Construction

[0011] from figure 1 , figure 2 It can be seen from the figure that a multi-square indexing device for milling includes a crankshaft support positioning mechanism and an indexing mechanism. The support positioning mechanism includes a V-shaped support block 8 installed on the clamp body 7, a positioning column 9, and the like. The V-shaped support block 8 is installed and fixed on the clamp body 7 with screws 6, and is supported under the main journals at both ends of the crankshaft 10. It cooperates with the crankshaft pressing mechanism 1 to clamp and fix the crankshaft 10. The positioning column 9 is a plug-in positioning column. Under the crankshaft 10 a connecting pin. Crankshaft pressing mechanism 1 belongs to prior art, can be mechanical, hydraulic pressure or pneumatic, is used for compressing or unclamping crankshaft two ends main journal.

[0012] The indexing mechanism of the present invention includes an indexing plate 2, a positioning pin 4, a positioning bloc...

Abstract

The invention relates to a polyhedron-milling dividing device. The device comprises a crankshaft support positioning mechanism and a dividing mechanism, wherein a V-shaped support block of the support positioning mechanism is supported below main journals at two ends of a crankshaft and is matched with a crankshaft pressing mechanism to clamp and fix the crankshaft; the diving mechanism comprises a dividing plate, a positioning pin and a positioning block; a blind hole matched with a large end excircle of the crankshaft is axially formed in the center of the dividing plate; the dividing plate is arranged and fixed at a large end of the crankshaft by a compression screw; a plurality of dividing positioning holes are distributed on the outside periphery of the blind hole of the dividing plate; the positioning block is arranged on a clamping apparatus body; the upper end of the positioning block is provided with a U-shaped groove with an upward opening; and the positioning pin passes through the U-shaped groove and is inserted into the dividing positioning hole on the dividing plate to perform corresponding circumferential dividing and positioning. The polyhedron-milling dividing device has the advantages of compact structure, reliable positioning and high efficiency of dividing actions, is suitable for cooperating with the clamping apparatus body and the crankshaft pressing mechanism to divide and clamp the crankshaft, and finishes the processing of flat surface milling or polyhedron milling of the crankshaft at a small head on a plain milling machine.

Description

technical field [0001] The invention relates to an indexing mechanism for crankshaft square milling, in particular to a multi-square indexing device for milling. Background technique [0002] We know that in the production and manufacture of crankshafts, the crankshaft must be clamped, positioned, and indexed in some manufacturing processes for processing operations. For example: Some crankshafts need to be flattened or hexagonally milled at the small head, which is usually completed on an ordinary milling machine by using a dividing head and a fixture. This method is labor-intensive and time-consuming, has a long production cycle, many clamping times, and low production efficiency, which is not suitable for mass production. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the above-mentioned prior art, and provide a milling multi-party indexing device with reasonable structure, simple manufa...
