Abstract
The utility model discloses a fixture for processing a crowned-tooth gear, capable of limiting the axial movement and the rotation degree of freedom of a workpiece. The fixture comprises a mandrel (1) and is characterized in that: a step (7) is arranged on the mandrel (1), a positioning pin (2) corresponding to a key slot on a tooth blank (3) and a taper sleeve (4) for centering the tooth blank (3), wherein the other end of the mandrel (1) is provided with a fine-thread nut (6) which fixes the tooth blank (3) on the mandrel (1). The fixture disclosed by the utility model has a simple structure, is convenient to operate and use, and can realize accurate centering and positioning; fine thread is utilized for fastening, thus being favorable for clamping and loosening of the workpiece; meanwhile, due to the adoption of the design of an open washer, the workpiece clamping time is reduced, and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of anchor clamps, and specifically a kind of Gear Processing is used anchor clamps, particularly relates to a kind of fixture for processing with crown-shaved gear of restriction workpiece circumference rotation.
Background technology
At present, in the processing of crown-shaved gear, the center of barreled tooth flank reference circle and tooth portion sphere should guarantee concentric, and location dimension was consistent when this just required when the processing profile of tooth, will guarantee each product clamping.Owing to add the influence that profile of tooth cutting in man-hour receives several directive effect power, frock must Control Shaft to the free degree of circumference, could guarantee the crudy of product.
Summary of the invention
The purpose of the utility model provides a kind ofly to be had the restriction workpiece and moves axially the fixture for processing with the crown-shaved gear of rotary freedom.
The utility model is to adopt following technical scheme to realize its goal of the invention; A kind of fixture for processing of crown-shaved gear; It comprises axle; Axle be provided with step, with the tooth base on the corresponding alignment pin of keyway and to the tapered sleeve of tooth base centering, the other end of axle is provided with the tooth base is fixed on the serrated nut on the axle.
The utility model is a quick-clamping, is provided with open washer between serrated nut and the tooth base.
Because adopt technique scheme, the utility model has been realized goal of the invention preferably, it is simple in structure; Easy for operation, ability precision centering and location adopt fine thread fastening; Help the clamping, locking of workpiece; Adopt the open washer design simultaneously, reduce the clamping time of workpiece, improved production efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Can know by Fig. 1; A kind of fixture for processing of crown-shaved gear; It comprises axle 1, axle 1 be provided with step 7, with tooth base 3 on the corresponding alignment pin 2 of keyway and to the tapered sleeve 4 of tooth base 3 centering, the other end of axle 1 is provided with tooth base 3 is fixed on the serrated nut 6 on the axle 1.
The utility model is a quick-clamping, is provided with open washer 5 between serrated nut 6 and the tooth base 3.
When the utility model uses; Tooth base 3 must guarantee technological datum position dimension precision, guaranteeing the uniformity of product clamping position, and the alignment pin 2 of at first tooth base 3 being aimed at axles 1 axle 1 of packing into; Technological datum position one end is near step 7; Alignment pin 2 adopts the cylinder design, limits the rotary freedom of tooth base 3 in process, guarantees the profile accuracy of product; Feel relieved with tapered sleeve 4 again, do not receive the influence of taper hole manufacturing tolerance to guarantee tooth base 3 clampings; The open washer 5 of packing into then with serrated nut 6 fastening getting final product, adopts fine thread 6 fastening, helps the clamping, locking of workpiece, adopts open washer 5 designs simultaneously, reduces the clamping time of tooth base 3, has improved production efficiency.Add man-hour; Adopt forming process processing profile of tooth; On CNC milling machine, divide tooth processing, it comprises cutter hub 8, cutter head 9 milling cutter, and the shape of cutter head 9 cutting edges is identical with the slot form size at the maximum position of crown-shaved gear cydariform; Cutting edge comprises involute section, easement curve section, arc section, and the top of cutting edge is a wholecircle arc light slip.The present embodiment milling cutter adopts disc milling cutter; Milling cutter is walked circular trace or tooth base 3 is walked circular trace (present embodiment is that tooth base 3 is walked circular trace with workbench in the teeth directional direction) with workbench in the teeth directional direction in the teeth directional direction; Whenever after processing a cydariform face of the gear teeth; Carry out calibration, reprocess the cydariform face of another gear teeth, until processing whole gear teeth.
Claims (2)
1. the fixture for processing of a crown-shaved gear; It comprises axle (1); It is characterized in that axle (1) is provided with step (7), the alignment pin (2) corresponding with the last keyway of tooth base (3) and the tapered sleeve (4) that tooth base (3) is felt relieved, the other end of axle (1) is provided with tooth base (3) is fixed on the serrated nut (6) on the axle (1).
