[0002] In the field of heavy-duty horizontal lathes, worm gears play a crucial role in precisely controlling linear motion, bearing heavy loads, maintaining positional stability, and are used in applications with limited space. Insufficient precision of the worm gear can affect the positioning and repeatability accuracy of the machine tool's moving parts, leading to unstable movement of the machine tool's moving parts. It can also cause problems such as accelerated wear, reduced transmission efficiency, decreased load capacity, increased failure rate, and impaired self-locking performance of the worm gear.

[0003] Traditionally, worm gear rods are processed using a special machine. However, this machine suffers from problems such as high cost, complex operation, high maintenance requirements, limited applicability, and low production efficiency. As a result, its overall performance and production efficiency cannot meet the needs of mass production of worm gear rods. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides a heavy-duty CNC horizontal lathe worm gear turning device, which can significantly improve machining efficiency while ensuring machining accuracy, and meet the needs of mass production of worm gears.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a heavy-duty CNC horizontal lathe worm gear turning device, including a base plate, a positioning fixture, a pressure plate, a tool bar and a forming tool. The base plate is a circular plate, and a vertical positioning fixture is fixedly connected to both sides of the center of the top of the base plate. Between the two positioning fixtures, a vertical tool bar is arranged above the center of the top of the base plate, and a horizontal forming tool is fixedly installed at the lower end of the tool bar.

[0006] At the end of the two positioning fixtures near the tool holder, two pressure plates with vertical spacing are installed on both the front and rear sides of the positioning fixture, and a pressure plate is also installed at the top center of this end of the positioning fixture.

[0007] Furthermore, the two positioning jigs are staggered on the base plate, and the center lines of the two positioning jigs are not on the same straight line.

[0008] Furthermore, the cutting tool body at the tip of the forming tool is arranged horizontally.

[0009] The utility model discloses beneficial effect is: the utility model discloses with the processing method of worm mother tooth bar special machine compares, this device can improve processing efficiency, reduce processing time, guarantee processing accuracy simultaneously, especially suitable for the demand of worm mother tooth bar mass production on the premise of guaranteeing worm mother tooth bar part accuracy, improve the production efficiency of turning.
