Problems solved by technology

For the processing of external threads of special-shaped parts with complex shapes such as automobile steering knuckles, it is difficult to realize the rolling method. At the same time, because of the complex shape, the parts need to be rotated to realize the rolling process of the threads during processing. The generation of centrifugal force makes it difficult to control the product quality

Embodiment

[0026] Such as Figure 1 to Figure 5 As shown, the present embodiment provides a jig for machining a screw thread of an automobile steering knuckle rod, which includes a support table 1 and a base 2 movably mounted on the support table 1, wherein the support table 1 may also be a work table; on the base 2 Two thimble mechanisms are set up front and rear, and the two thimble mechanisms are used to tighten the front and rear center holes of the steering knuckle 100 rod part, and position the workpiece during the thread rolling processing of the steering knuckle 100 rod part; one of the thimble mechanism The thimble can float along the axial direction of the rod part of the steering knuckle 100. If it is fixed, the workpiece is relatively heavy when the workpiece is installed and removed, which is difficult to install and remove, and the labor intensity of the operator is high, and it is easy to fall and damage the processing surface of the workpiece.

Abstract

The invention provides an automobile steering knuckle rod part thread machining clamp and device. The automobile steering knuckle rod part thread machining clamp comprises a supporting table and a base arranged on the supporting table, wherein two ejector pin mechanisms are arranged on the base in a positive opposite mode, and the ejector pin of one ejector pin mechanism can float in the axial direction; and the base is supported on the supporting table through a plurality of roller pins, the axes of the roller pins is parallel to the axis direction of the steering knuckle rod part, so that the base can horizontally float along the axis perpendicular to the axis of the steering knuckle rod on the supporting table, and a limiting structure used for limiting the horizontal floating range ofthe base is arranged on the supporting table or the base. According to the automobile steering knuckle rod part thread machining clamp and device, the steering knuckle is positioned and clamped through the front and back ejector pin mechanisms, the base can float on the supporting table in the left-right direction, the plastic deformation space of the product part and the product quality are ensured through a floating gap of the clamp.

Description

Technical field [0001] The invention belongs to the technical field of jigs and fixtures, and in particular relates to a jig and a device for machining a screw thread of an automobile steering knuckle rod. Background technique [0002] At present, in the manufacturing industry, in the external thread processing methods, the commonly used methods are: one is turning processing, the other is milling processing, and the other method is rolling processing. Most of the objects processed by the rolling method are some relatively regular parts, such as shaft parts and tube parts. However, it is difficult to process the external threads of special-shaped parts with complex shapes such as automobile steering knuckles. It is difficult to realize the rolling method. At the same time, because of the complex shape, the parts need to be rotated to achieve the thread rolling. The generation of centrifugal force makes it difficult to control the product quality. One of the great advantages of ...
