SU1351761A1 - Arrangement for dressing abrasive worm - Google Patents

Abstract

The invention relates to a machine tool industry and can be used in gear grinding machines operating with an abrasive screw. The purpose of the invention is to improve the accuracy of editing by eliminating the cyclic error in the kinematic chain. A device for dressing an abrasive worm 1 on a gear grinding machine comprises a sliding carriage 17 with a right tool 18 connected to the shaft of the rotating abrasive screw I by means of a kinematic chain consisting of translational and rotational branches. In the straightening device, a worm gear is installed in the forward movement branch, which includes the worm to 10 and the worm gear 1. A rotary drum 12 is located on the axis of the worm gear 11. The drum 12 is connected by flexible belts 14 to a movable shaft 15 that moves the progressively moving carriage and the right tool 18. 1 Il. w oo JV O5 / 7 / 4- / "

Description

The invention relates to a machine tool industry and can be used on gear grinding machines operating with an abrasive screw.

The purpose of the invention is to improve the accuracy of editing by eliminating the cyclic error in the kinematic chain.

The drawing shows a diagram of the editing device.

but-forward movement, while turning at an angle not exceeding 120 °. The maximum stroke of the rod is approximately the diameter of the drum. The tuning of the guitar 6-9 is carried out so that in one turn of the abrasive worm 1 rod 15 and the carriage 17 associated with it moves by the step size of the abrasive worm 1. The rotary drum 12 with ribbons 14 can be performed. The device contains an abrasive wrench. . m Then the adjustment device straightening in to 1, is rotated by the pr-simplifies.

water 2, pinch 3 and 4 kinematic-Since the transfer rotary drum -

In this circuit, the 5 dividing device into zailenty-hg rod does not give cyclic pogues (construction not shown), a tuner-resolution guitar, and the worm gear can be step removed, consisting of gears 6–9, complete with high accuracy, then cyclically direct gear, which includes a screwdriver to the 10th cusps at the output of the device and a worm gear 11, a rotary drum 12 mounted on the axis 13 of a worm gear 11. The rotation of the drum 12 by means of flexible steel bands 14 is connected to a movable rod 15 that moves JQ guide 16 and rests on the carriage 17 with the right conductive tool 18. A branch rotational movement comprises a screw 1, the drive pinion 2 and 3, 4, 6 and 8. The branch translational movement

includes a gear 9. a worm 25 of the forward movement, and a placement- transfer, 10-11, a drum 12, a tape 14 different on the shaft, an abrasive worm to, while

the rod 15. the cage is connected to the shaft by means of a ki. The device operates as follows in the nematic circuit consisting of branches at once of the scaling and translational movements.

The rotational movement from the drive 2 is not different, that, with the aim of increasing the abrasive worm to 1 through the neck - 30, the accuracy of the straightening, the device is equipped with 3, 4, guitar 6-9 tunings, black-introduced into the branch of the translational motion can significantly reduce. This makes it possible to improve the accuracy of tooth-grinding machines operating abrasive worm.

Claims (1)

Invention Formula An abrasive screw dressing device containing a carriage with a right-handed tool in to 10, the worm gear 11 on the rotary drum 12, which moves the rod 15 by means of steel flexible bands 14 and, together with the rod, the carriage 17 with the right tool 18. The carriage presses against the rod 15 by force P. When the device is in operation, the drum does not make a complete rotation, but makes a return35 The SRI is a worm gear, placed on the shaft of the worm wheel with the possibility of reciprocating-rocking1 movement with a drum with flexible ribbons and installed with the possibility of reciprocating movement and interoperating with the carriage by a shaft, while the latter is connected drum through the middle of flexible tapes. the cacical errors at the device output  translational movement, and an abrasive worm placed on the shaft to edits can be significantly reduced. This makes it possible to improve the accuracy of tooth-grinding machines operating abrasive worm.
