Embodiment 1

[0017] Two hydraulic presses are respectively installed on the left and right sides of the workpiece, one for hydraulic output facing forward, and one for hydraulic output facing backward. The fixture is divided into two parts, both of which are fixed in the middle. The tensioning part on the top, the clamp rotates under the action of hydraulic pressure, so that the tensioning part in the middle of the gear is displaced laterally, thereby tightening the gear.

Embodiment 2

[0019] The two hydraulic presses are relatively arranged on the left and right sides of the workpiece, and the hydraulic output is inward. The fixture is divided into two parts, both of which are fixed in the middle. The lower side of the fixture is connected to the output end of the hydraulic machine, and the upper side of the fixture is set in the through hole in the middle of the gear. The clamp moves horizontally under the action of hydraulic pressure, so that the upper side of the clamp moves horizontally in the middle of the gear, thereby tightening the gear.

Embodiment 3

[0021] Two hydraulic machines are set opposite to the left and right sides of the workpiece, and the hydraulic output is performed inwardly. The fixture is divided into two parts, the middle crosses, and the outer side is connected to the output end of the hydraulic machine. The middle part of the fixture is set in the through hole in the middle of the gear. The horizontal movement is generated under the gear, so that the cross part of the clamp in the middle of the gear is displaced in the horizontal direction, thereby tightening the gear.

Abstract

The invention discloses a hydraulic tensioning method for fixing a gear. The method comprises the following steps that firstly, clamp fixing is carried out, and a clamp penetrates through a through hole in the middle of the gear; secondly, hydraulic pressure output is carried out, a hydraulic machine outputs hydraulic pressure to enable the clamp to move or rotate, and therefore the clamp in the through hole in the middle of the gear to shift, the gear is tensioned, and the gear can be machined conveniently; thirdly, hydraulic resetting is carried out, after machining is completed, hydraulic resetting is carried out, the clamp moves or rotates reversely, and therefore the clamp in the through hole in the middle of the gear is reset to an initial state; fourthly, a workpiece is taken out, and the machined workpiece is taken out. According to the method, the clamp moves or shifts through the hydraulic pressure, and therefore the gear is tensioned, the output hydraulic pressure is ingeniously converted into tensile force, the gear is tensioned in the through hole in the middle of the gear, the conception is ingenious, the structure is reasonable, and excessive machining due to the fact that the fixing clamp clamps the gear due to vibration can be avoided.

Description

technical field [0001] The invention relates to a gear processing method, in particular to a hydraulic tensioning gear fixing method, which is mainly used for fixing gears in batch processing. Background technique [0002] Gears are mechanical parts with teeth that mesh with each other. The application of gears in transmission appeared very early. More than 300 BC, the ancient Greek philosopher Aristotle explained the problem of using bronze or cast iron gears to transmit rotary motion in "Mechanical Problems". The famous Greek scholars Aristotle and Archimedes have both studied gears. The famous Greek inventor Gutisibios evenly inserted pins on the edge of the circular plate table to make it mesh with the pin wheel. He applied this mechanism to engraved leaks. This is about 150 BC. In 100 BC, the Alexandrian inventor Heron invented the odometer, using gears in the odometer. In the 1st century AD, gear transmission was also used in the waterwheel mill made by the Roman a...
