Embodiment Construction

[0028] combine figure 1 and figure 2 As shown, the present invention includes an expansion sleeve positioning base 1, one end of the expansion sleeve positioning base 1 is fixed to the machine tool, and the other end of the expansion sleeve positioning base 1 is fixed with a gear positioning cover 2, and the gear positioning cover 2 faces away from the expansion sleeve. One end of the sleeve positioning base 1 is provided with a gear positioning groove 10. The end of the expansion sleeve positioning base 1 passes through the bottom of the gear positioning groove 10 and is located in the gear positioning groove 10. The expansion sleeve positioning base 1 is located in the gear positioning groove 10. One end of the groove 10 is sleeved with an expansion sleeve 3, and the expansion sleeve positioning base 1 is fixed to one end of the hydraulic pull rod 4 by a screw 6, and the other end of the hydraulic pull rod 4 passes through the set of the expansion sleeve positioning base 1....

Abstract

The invention discloses a hydraulic expanding sleeve type tool for gear tooth shape processing. One end of an expanding sleeve positioning basic body is fixed to a machine tool; the other end of the expanding sleeve positioning basic body is fixed to a gear positioning cover; one end, back to the expanding sleeve positioning basic body, of the gear positioning cover is provided with a gear positioning slot; the end part of the expanding sleeve positioning basic body passes through a slot bottom of the gear positioning slot, and is positioned in the gear positioning slot; one end, in the gear positioning slot, of the expanding sleeve positioning basic body is provided with an expanding sleeve in a sleeved manner; the expanding sleeve positioning basic body is fixed to one end of a hydraulic drawbar through a bolt; the other end of the hydraulic drawbar passes through a central through hole of the expanding sleeve positioning basic body, and is fixed to a hydraulic rod; the circumferential surface, which is in contact with the expanding sleeve, of the expanding sleeve positioning basic body is a slope surface A; the position, which corresponds to the slope surface A, of the expanding sleeve is provided with a slot; the slot wall of the slot is matched with the slope surface A; and the contact part of a gear and the expanding sleeve is positioned in the positioning slot. According to the invention, the hydraulic expanding sleeve type tool is used for fixing the gear, so that the gear can smoothly be subjected totooth shape processing.

Description

technical field [0001] The invention relates to the field of gear processing, in particular to a gear tooth profile processing hydraulic expansion sleeve tooling. Background technique [0002] Conventional processing of bevel gear tooth profile: For products with a gear inner hole diameter greater than 65 mm, the inner hole can be tightened with expansion plates for processing; for products with a gear inner hole diameter less than 25 mm, pull nails can be used to tighten the inner hole . However, for products with small disc gears with an inner hole diameter between 25mm and 65mm, the corresponding tooling and fixtures are difficult points during tooth profile processing, especially the tooth profile and phase requirements are high, the cumulative error of tooth jumps should be small, and the tooth surface accuracy High-quality products must be designed and invented a fixture device that is durable, convenient and fast for product loading and unloading, reduces labor inten...
