Detailed Description
The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.
Examples
As shown in fig. 1 to 5, the present embodiment provides a screw thread machining fixture for a steering knuckle rod of an automobile, which includes a support table 1 and a base 2 horizontally movably mounted on the support table 1, wherein the support table 1 may also be a workbench; two ejector pin mechanisms are arranged on the base 2 in a front-back opposite manner and are used for tightly ejecting front and back center holes of the rod part of the steering knuckle 100 and positioning a workpiece during thread rolling processing of the rod part of the steering knuckle 100; the thimble of one of them thimble mechanism can follow the axial of knuckle 100 pole portion floats, if fixed, because of the work piece is heavier when the dress gets the work piece, the dress gets the difficulty, and operating personnel intensity of labour is big, and easily falls down, damages the work piece machined surface.
The base 2 is supported on the support table 1 through a plurality of roller pins 6 (or called rollers), and the roller pins 6 are arranged side by side and horizontally along the left-right direction; the axis of the needle roller 6 is parallel to the axial direction of the rod part of the steering knuckle 100, so that the base 2 can float horizontally (i.e. float left and right) on the support table 1 along the direction perpendicular to the axial direction of the rod part of the steering knuckle 100, and the support table 1 or the base 2 is provided with a limit structure for limiting the horizontal floating range of the base 2. When the threads are rolled, the driving thread rolling wheel and the driven thread rolling wheel shown in fig. 3 simultaneously rotate clockwise and downwards, the driven thread rolling wheel pushes the workpiece and the clamp to move from right to left and contact with the driving thread rolling wheel, the driven thread rolling wheel continues to move leftwards after the contact, the driving thread rolling wheel and the driven thread rolling wheel simultaneously cut into the workpiece downwards and roll threads, after the machining is completed, the driven thread rolling wheel exits, and due to the fact that the needle roller mechanism is arranged below the base, the workpiece and the clamp automatically exit from the driving thread rolling wheel and exit from a certain distance due to the fact that extrusion force of the driven thread rolling wheel disappears. The cutting-in and withdrawing distance is limited by a limiting structure (namely a lateral limiting block 8).
The knuckle 100 is positioned and clamped through a front and rear thimble mechanism and supported through a support structure; the base 2 can float along the left and right directions on the support table 1, so that the workpiece can float along the left and right directions to conform to the change of the position of the rod part under the action of the rolling acting force in the rolling process; the plastic deformation space and the product quality of the product parts are ensured through the floating clearance of the clamp. Because the steering knuckle is a special-shaped part in structure, the gravity center is close to the fork part of the steering knuckle, and the traditional tool suitable for regular shaft parts cannot be used for clamping; if the thimble of the clamp floats up and down or left and right on the thimble seat along the radial direction, the steering knuckle can be raised, and the defects of wrong teeth or tooth decay and the like can be caused; the fixture floats on the support table, so that the workpiece can float, and the rolling defect caused by unstable gravity center of the steering knuckle is avoided; the stability of steering knuckle clamping and floating is guaranteed, and rolling quality is further guaranteed.
A gap is reserved between the base 2 and the support table 1 in the vertical direction, and the base is supported by the needle rollers 6; the needle rollers 6 are provided in a single set or two or more sets at intervals along the axial direction of the rod portion of the knuckle 100, and in this example, two sets are provided along the front-rear direction, and correspond to the front and rear portions of the base 2, respectively.

Wherein, in order to ensure the stability of horizontal floating, the base 2 is prevented from sliding out of the supporting platform 1; when only the support table 1 or the base 2 is provided with the mounting groove, the depth of the roller pin 6 embedded into the lower surface of the base 2 or the upper surface of the support table 1 is greater than the radius of the roller pin 6; taking this example as an example, the needle rollers 6 are disposed in the mounting grooves on the lower surface of the base 2, and the range in which the needle rollers 6 are exposed on the lower surface of the base 2 is about one third of the circumference.
In one embodiment, the needle rollers 6 are horizontally arranged along the left-right direction, in order to prevent the needle rollers 6 from mutually extruding and interfering when floating left and right, so that the needle rollers 6 are partially overlapped to influence floating and rolling processing; the jig further includes spacers for spacing the adjacent needle rollers 6 from each other in the horizontal alignment direction.
Specifically, the mounting grooves may be arranged as a plurality of spaced grooves corresponding to the number of the needle rollers 6, and each needle roller 6 is correspondingly mounted in one groove; the grooves may be rectangular, arcuate, etc.
