Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

As shown in the figures, the present embodiment provides a fixture for producing a gear of an excavator, which includes a workbench 1, wherein a front support 2 and a rear support 3 are arranged at the top end of the workbench 1; a loop bar 4 is arranged on one side surface of the front bracket 2 close to the rear bracket 3, a central hole of the gear can be arranged on the loop bar 4, and a limiting hole 5 is arranged in the center of the loop bar 4; rear bracket 3 keeps away from pneumatic cylinder 6 is installed to one side of fore-stock 2, the front end of pneumatic cylinder 6 pierces through rear bracket 3 be connected with spacing head 7 of spacing hole 5 mutually supporting, during the dress card, pneumatic cylinder 6 stretches out, makes spacing head 7 insert in spacing hole 5 to the pressure disk 8 of the one end of fore-stock 2 is kept away from through spacing head 7 installs the gear is vertical at

pressure disk

8 and 3 supports of rear bracket, makes things convenient for the tooth of the gear to grind, and easily adjusts the dress card fixed.

The loop bar 4 includes rubber sleeve 9 and installation pole 10, spacing hole 5 is located on the rubber sleeve 9, installation pole 10 other end fixed connection the rubber sleeve 9. Make in spacing head 7 inserts spacing hole 5, can make the expansion of rubber sleeve 9, the outer wall of rubber sleeve 9 closely laminates with the centre bore of gear, inserts when spacing head 7 more inwards, and pressure is big more between the centre bore of rubber sleeve 9 and gear to it is more firm to make the gear fixed.

Be equipped with mounting hole 11 on the fore-stock 2, installation pole 10 one end can dismantle connect in mounting hole 11, spacing head 7 demountable installation in the telescopic link front end of pneumatic cylinder 6. Spacing hole 5 passes through threaded connection with the telescopic link, and installation can all be dismantled to spacing head 7 and rubber sleeve 9, conveniently processes the gear of different specifications, increases the equipment practicality.
