Embodiment Construction

[0012] From figure 1 It can be seen from the figure that a crankshaft automatic indexing and pressing device includes an upper pressing block 1, a lead screw 2, a locking bolt 3, a bracket 4, a chuck 5, a rotating shaft seat 6, an indexing rotating shaft 7, and an electromagnetic brake 8. Indexing motor 19, etc.

[0013] Described support 4 is " L " right-angled shape, and its one right-angled side is provided with slideway, and rotating shaft seat 6 installation holes and indexing motor 19 installation holes are arranged on the other right-angled side. Upper pressing block 1 is installed on the slideway of support 4, can slide up and down. The indexing rotating shaft 7 is installed in the rotating shaft seat 6, and the indexing motor 19 is installed on the motor mount 18 fixed on the support 4 by bolts 17. Specifically, there is a flat plate on the back side of the slideway for supporting the screw 2, and one end of the upper pressing block 1 is provided with a tip downward...

Abstract

The present invention relates to a crankshaft automatic indexing holddown device, which comprises a support, an upper pressing block, a chuck, an electromagnetic brake, an indexing rotating shaft, a rotating shaft seat and an indexing motor. The support is L-shaped, and a slideway is arranged on one - leg of the support, while the rotating shaft seat is arranged on the other right-angle side of the support. The upper compact heap is arranged on the slideway of the support; the indexing rotating shaft is arranged on the rotating shaft seat, wherein the chuck is arranged on the upper end of the indexing rotating shaft, and the lower end of the indexing rotating shaft is connected with the electromagnetic brake; a crankshaft is clamped on the chuck and is compressed by using the upper compact heap; the indexing rotating shaft is driven by a synchronous belt wheel and a synchronous belt through the indexing motor; under the driving of the indexing motor, the chuck is driven to rotate by a predetermined angle and is locked by the electromagnetic brake. The crankshaft automatic indexing holddown device provided by the present invention has the advantages of compact structure, reliable positioning, efficient compacting motion and low labor intensity so that the crankshaft automatic indexing holddown device is especially suitable for the indexing compaction when drilling crankshaft flange holes.

Description

technical field [0001] The invention relates to an indexing and pressing device, in particular to an automatic indexing and pressing device for a crankshaft which uses a rocker drill to drill the flange hole of the crankshaft plate during the production process of the crankshaft. Background technique [0002] We know that a group of circular holes are evenly distributed on the end face of the large plate flange of the crankshaft. When drilling this group of round holes on the radial drill, it is necessary to use the drill template for indexing. That is, move the gear box of the radial drill so that the drill bit is aligned with the pilot hole on the drilling template, and then drill. This indexing method not only has low indexing accuracy, but also is difficult to realize the automation of drilling on the radial arm drill. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the above-mentioned ...
