Problems solved by technology
[0003] Car sunroofs are generally composed of front beams, rear beams, and sunroof guide rail beams on both sides. The production process of the current sunroof guide rails is relatively cumbersome. The key is that repeated positioning is required. The positioning is not accurate, resulting in rework due to substandard quality of the sunroof guide rails.

specific Embodiment
[0030] Such as Figure 1-2 Shown, the present invention provides a kind of processing technology of vehicle sunroof guide rail, and specific embodiment is as follows, comprises the following steps:
[0031] Step 1: Extrude the guide rail body with a special aluminum profile forming machine;
[0032] Step 2: Use the side wall A of the groove in the middle part of the lower side of the guide rail body as the Y-direction positioning surface, use the end of the guide rail body to perform X-direction positioning, and punch out the boss 1 at the edge of the guide rail body. The two ends are stamped out with limit round protrusions 3, and at the same time, a lettering part 2 is set on one side of the boss 1;
[0033] Step 3: Take the limit circle protrusion 3 as the positioning reference, and carry out straight milling on the end and side of the guide rail body, and use the limit circle protrusion 3 as the positioning reference to make good use of the positioning reference in the pr...

The invention discloses a processing technology of a sunroof guide rail for a vehicle, which comprises the following steps: extruding the guide rail body from an aluminum profile; using the side wall of the groove in the middle part of the lower side of the guide rail body as a Y-direction positioning surface, and using the end of the guide rail body to carry out the X-direction positioning. Positioning, punch out the boss at the edge of the guide rail body, and punch out the limit circle points at both ends of the side where the boss is located; take the limit circle point as the positioning reference, and straighten the end and side of the guide rail body. Milling; chamfering the two ends of the two flexible shaft grooves on the guide rail body; turning the guide rail body 90°, taking the side wall of the groove as the reference, stamping and forming the mechanical group running notch and punching hook on the guide rail body; repairing burrs , polished, and anodized on the surface; lay the guide rail body flat, and process three side rivet nuts on its vertical mounting plate. The invention has smooth process and high processing precision, can well meet the needs of skylight guide rail installation, and improves the production efficiency of the skylight guide rail.
Description
technical field [0001] The invention relates to the field of auto parts, in particular to a processing technology of a sunroof guide rail for a vehicle. Background technique [0002] The car sunroof is installed on the roof, which can effectively circulate the air in the car and increase the entry of fresh air. At the same time, the car window can also broaden the field of view and meet the shooting needs of mobile photography. Car sunroofs can be roughly divided into: sliding outside, built-in, built-in and turned-out, panoramic and curtain. It is mainly installed on commercial SUVs, sedans and other vehicles. [0003] Car sunroofs are generally composed of front beams, rear beams, and sunroof guide rail beams on both sides. The production process of the current sunroof guide rails is relatively cumbersome. The key is that repeated positioning is required. The positioning is not accurate, resulting in rework due to substandard quality of the sunroof guide rails. Contents...
