Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. This manufacturing technique is very clear to those skilled in the art.

[0026] With the center distance A=125, the number of worm heads is 2, the transmission ratio i=20.5, the number of worm gear teeth surrounded by the worm is 4.5, the axial modulus m=4.927, the arc radius of the worm tooth root is 105.43, the arc radius of the worm tooth top is 97.55, and the length of the working part of the worm 62, a right-handed plane quadratic enveloping toroidal worm with a base circle diameter of 78 and a full tooth height of 7.88 is taken as an example.

[0027] Except for the helical surface of the worm, other dimensions are cut in place first. When rough machining the right side of the spiral surface, the width of the top edge of the cutting tool is 5, which is less than the root groove width of 7.19, and greater than half of the tooth root groove ...

Abstract

The invention relates to the technical field of machinery, specifically relates to a CNC (computerized numerical control) combined turning and grinding machine tool for four-linkage enveloping worms and a processing method thereof. The machine tool and processing method thereof provided by the invention are characterized in that a main shaft motor 3 drives a main shaft 5 and an enveloping worm 7 to rotate around a C-axis by a synchronous belt, a Z-axis servo motor 10 drives a ball screw 17 to lead a large support plate 11 to move along a Z-direction guide rail 16 by the synchronous belt, an X-axis servo motor 19 drives a ball screw 13 to lead a small support plate 15 to move along an X-direction guide rail 12 by a coupler, a Y-axis servo motor 18 drives a CNC rotary table 14 to rotate around a Y axis by gears, a CNC tool rest or grinding head is fixedly connected to the CNC rotary table, a grinding head motor 20 drives a grinding wheel 21 to rotate around a B-axis by the synchronous belt, and the grinding wheel and the motor synchronously rotate around an A-axis by turning a hand wheel. Compared with the prior art, the machine tool disclosed by the invention is simple and novel instructure, convenient and safe in operation, high in processing efficiency and wide in application range; and in addition, the machine tool can rotate at a high speed, and the operations of turning and grinding are completed on a same machine tool, therefore, the machine tool is complete in function, high in reliability, strong in environment adaptivity, and more accurate in transmission precision and machining precision.

Description

technical field [0001] The invention relates to the field of mechanical technology, and relates to a machine tool for processing toroidal worms, including its turning and grinding methods, in particular to a four-linkage toroidal worm CNC turning-grinding compound machine tool and its processing method. Background technique [0002] Domestic patent publication number: CN1907615A discloses a toroidal worm CNC machine tool capable of virtual center distance. The machine tool has the following four coordinated coordinate movements: the rotary motion A (parallel to Z) of the main shaft (workpiece) around its own axis, Two mutually perpendicular translational movements X, Z of the tool table in the horizontal plane, the tool table around its own axis O 0 (perpendicular to the XZ plane) rotary motion Y. On the one hand, the tool table rotates with the main shaft A according to the required transmission ratio I=A / Y; The concave and convex toroidal worms with large center distance...
