Description

Technical Field

[0001] The utility model belongs to the technical field of roller cutters, and in particular relates to a roller cutter used for rolling ring grooves of hollow automobile half shafts. Background Art

[0002] Shaft grooving involves rolling the surface of a shaft to form grooves. A rolling tool applies pressure to the workpiece surface, causing the surface metal to plastically flow, thereby creating grooves. Rolling is a non-cutting plastic working method. However, existing roller tools have a fixed rolling head and toolholder, which results in uneven force application as the machining process progresses, affecting machining accuracy and quality. Summary of the Invention

[0003] The purpose of the utility model is to solve the above problems and provide a roller cutter for rolling ring grooves of hollow automobile half shafts.

[0004] To achieve the above objectives, the present invention adopts the following technical solutions: a roller tool for rolling annular grooves on hollow automotive axles, comprising a grooving tool holder, a roller mounting portion on one side of the grooving tool holder, and ring-grooved rollers disposed at the upper and lower ends of the roller mounting portion, respectively, via a rotatable mounting structure. The rotational axes of the two ring-grooved rollers are vertically parallel, and a processing space is formed between the two ring-grooved rollers, located on one side of the roller mounting portion and for accommodating the hollow automotive axle. The circumferential outer sides of the ring-grooved rollers each have a ring-grooving assembly extending beyond the roller mounting portion. The ring-grooved rollers are mounted on the roller mounting portion of the grooving tool holder via the rotatable mounting structure, and the hollow automotive axle is disposed in the processing space. The ring-grooved rollers process the surface of the hollow automotive axle through the ring-grooving assembly.

[0005] In the aforementioned roller tool for rolling annular grooves on hollow automotive axles, the two annular groove rollers are identical in size and made of metal, and their rotational axes are parallel to the center axis of the hollow automotive axle. This ensures precision in machining the annular grooves.

[0006] In the above-mentioned roller tool for rolling annular grooves of hollow automobile half-axles, the rolling annular groove assembly includes a plurality of annular ribs formed in sequence on the circumferential outer side of the annular groove roller, and the annular ribs are divided into two narrow ribs symmetrically arranged at both ends of the annular groove roller and two wide ribs symmetrically arranged between the two narrow ribs.

[0007] In the aforementioned roller cutter for rolling annular grooves on hollow automotive axles, the roller mounting portion includes two roller mounting plates arranged vertically and parallel to each other on one side of the grooving tool holder. One of the two annular groove rollers is rotatably mounted between the upper ends of the two roller mounting plates, and the remaining one is rotatably mounted between the lower ends of the two roller mounting plates. This allows the two annular groove rollers to operate simultaneously, thereby improving efficiency.

[0008] In the above-mentioned roller tool for rolling annular grooves of hollow automobile half-axles, the upper and lower ends of the roller mounting plate and the side away from the groove rolling tool handle respectively have arc-shaped transition parts, and the arc-shaped transition parts on the outer sides of the same end corresponding to the two roller mounting plates are arranged corresponding to each other and the outer sides of the annular groove rollers respectively extend beyond the outer sides of the arc-shaped transition parts.

[0009] In the aforementioned roller cutter for rolling annular grooves on hollow automotive axles, the roller mounting plates each have an arcuate recessed portion in the middle, recessed toward the groove cutter handle. A curved transition forms between the arcuate recessed portion and the arcuate transition portion. The arcuate recessed portions in the middle of the two roller mounting plates are disposed in correspondence, thereby forming the aforementioned processing space. The hollow automotive axle contacts the two annular groove rollers through the processing space.

[0010] In the aforementioned roller cutter for rolling annular grooves on hollow automotive axles, the rotating mounting structure includes mounting holes vertically correspondingly disposed at the upper and lower ends of two roller mounting plates. A latch is inserted between the mounting holes on the corresponding ends of the two roller mounting plates. The annular groove roller is positioned circumferentially outside the latch, and a needle roller bearing sleeve is disposed between the circumferential inside of the annular groove roller and the circumferential outside of the latch. The needle roller bearing sleeve is used to rotate the annular groove roller, and the latch is used to secure the annular groove roller to the roller mounting plate.

[0011] In the above-mentioned roller tool for rolling ring grooves of hollow automobile half-axles, the grooving tool handle includes a vertically arranged and plate-shaped tool handle mounting portion, a plurality of tool handle mounting holes are provided on the tool handle mounting portion, and a connecting portion perpendicular to the tool handle mounting portion is provided on one side of the tool handle mounting portion. The roller mounting plates are respectively arranged on the side of the connecting portion away from the tool handle mounting portion, and the tool handle mounting portion, the connecting portion and the roller mounting plate are connected into an integrated structure.

[0012] In the aforementioned roller cutter for rolling annular grooves in hollow automotive axles, L-shaped clamping deformation grooves are respectively provided between the upper and lower ends of the roller mounting plate and the connecting portion. One end of the clamping deformation groove extends between the roller mounting plate and the connecting portion, and the other end communicates with the mounting hole. Adjustable clamping bolts are provided at the upper and lower ends of the roller mounting plate, extending through the clamping deformation grooves. The clamping deformation grooves are used to secure a latch, thereby ensuring the stability of the annular groove roller.

[0013] In the above-mentioned roller tool for the rolling ring groove of a hollow automobile half-axle, the end face of one end of the pin has a non-circular adjustment hole and a pointer mark on one side of the adjustment hole, and the other end of the pin is provided with a ring. The upper and lower ends of one of the two roller mounting plates are respectively provided with adjustment scale lines located on the circumferential outside of the mounting hole and corresponding to the pointer mark.

[0014] Compared with the existing technology, the advantages of this utility model are:

[0015] The device uses a clamping deformation groove and an adjustment scale line to adjust the fixed ring groove roller, thereby ensuring the normal operation of the ring groove roller. At the same time, through the design structure of the roller mounting part, the hollow automobile half-axle is set in the processing space, and the two ring groove rollers can stably process the hollow automobile half-axle, thereby improving the processing accuracy and quality.
