Flexible gear machining clamp

Abstract

The invention discloses a flexible gear machining clamp. The flexible gear machining clamp comprises an expansion sleeve and a clamp seat. The expansion sleeve is in a cylinder shape, and consists ofa plurality of steel blocks. The adjacent steel blocks are bonded together by using adhesive tapes. A center tie rod is disposed in the clamp seat, and the expansion sleeve is provided with a gland. The gland is provided with a connecting rod connected with the tie rod. Under the action of a telescopic device, the central tie rod can drive the gland to press down through the connecting rod to enable the gland to act on the expansion sleeve and move the expansion sleeve downwards. A tapered section is arranged at the upper end of the clamp seat, the outer diameter of the upper end of the tapered section is smaller than the inner diameter of the expansion sleeve, and the outer diameter of the lower end of the tapered section is larger than the inner diameter of the expansion sleeve, so thatthe outer diameter of the expansion sleeve is increased under the action of the tapered section during the downward movement, and a machined gear mounted on the expansion sleeve is expanded. The flexibility of expanding outward of the expansion sleeve is better, the machining requirements of gears of different models are better met, and the service life of the clamp is prolonged.

Description

technical field [0001] The invention belongs to the technical field of fixtures, in particular to a gear flexible processing fixture. Background technique [0002] Fixture refers to the device used to fix the processing object in the process of mechanical manufacturing so that it can occupy the correct position for processing or testing. In a broad sense, any process in the process is used to install quickly, conveniently and safely. The device of the workpiece can be called a fixture. [0003] Gear processing fixture refers to the special fixture used to fix the gear in the process of gear processing. There are various types of existing mechanical gears, so the selection of processing fixture models is also different. In the existing gear processing fixture Among them, the collet is made of a metal body, and the lower end of the fixture head is provided with gaps along the axial interval, so that although the collet can achieve the effect of expanding and fixing the gear o...

[0003] Gear processing fixture refers to the special fixture used to fix the gear in the process of gear processing. There are various types of existing mechanical gears, so the selection of processing fixture models is also different. In the existing gear processing fixture Among them, the collet is made of metal, and the lower end of the fixture head is provided with gaps along the axial interval. Although this can make the collet expand outward to fix the gear, the expansion degree is very insignificant, and the comparison of the model difference For obvious gears, it is necessary to customize a similar type of fixture to complete the fixed processing, which increases the cost of the fixture, and the wear between the chuck and the fixture seat is also very serious during such processing, which seriously affects the use of the fixture life
