Abstract
The utility model discloses a swaging chuck device of 7 fonts, including the chuck body, the chuck body includes the clamping part of front side and the connecting portion of rear side, and the upper end of clamping part links to each other with the front end of connecting portion, wholly becomes "7" font, the clamping part is semi-circular the semi-circular taper hole that extends around the lower extreme of clamping part is provided with, the front end diameter in semi-circular taper hole is less than the rear end the upper end of connecting portion is provided with and is used for installing the dovetail that extends on the swaging machine and about. When clamping, the semi-conical hole is adopted for clamping, so that the semi-conical hole can be effectively attached to the outer wall of the tubular part, and the clamping mark can not be generated in the follow-up process of the semi-conical hole and the hammer head; the dovetail groove is connected with the rotary forging machine, so that the feeding unit can be conveniently driven to feed the parts and the parts into a machine tool.
Description
Technical Field
The utility model belongs to the technical field of the rotary swaging, concretely relates to 7 font rotary swaging chuck device.
Background
In automotive transmissions, the steering shaft is usually a tubular part, and the tubular part is usually formed by swaging equipment. In the swaging process, a flat chuck is generally used to prevent the part from being clamped and deformed, but the chuck is suitable for parts which are long and require swaging at both ends, and in the case where only one end of the part requires swaging, the flat chuck is used to require a long part as a feeding unit and may generate a clamp mark on the surface of the part.
SUMMERY OF THE UTILITY MODEL
The utility model discloses plan to provide a rotary swaging chuck device of 7 fonts, at the rotary swaging in-process, can be effectively with the part centre gripping, and can not produce the clamp mark on the part.
Therefore, the utility model discloses the technical scheme who adopts does: a 7-shaped rotary swaging clamp device,
including the chuck body, the chuck body includes the clamping part of front side and the connecting portion of rear side, and the upper end of clamping part links to each other with the front end of connecting portion, wholly becomes "7" font, the clamping part semicircular in shape the lower extreme of clamping part is provided with the half cone hole that extends around, the front end diameter in half cone hole is less than the rear end the upper end of connecting portion is provided with and is used for installing the dovetail that extends about and on the rotary swaging machine.
Preferably, the root parts of the two ends of the semi-conical hole are provided with transition inclined planes which are tangent to the arc surfaces and inclined to the corresponding sides.
More preferably, the included angle between the inclined plane and the vertical line is 20 °.
More preferably, the taper of the semicircular taper hole is between 0.45 and 0.65 degrees.
More preferably, chamfers are provided on both left and right sides of the dovetail groove.
Further preferably, a coating is arranged on the semicircular conical hole.
The utility model has the advantages that: when clamping, the semi-conical hole is adopted for clamping, so that the semi-conical hole can be effectively attached to the outer wall of the tubular part, and the clamping mark can not be generated in the follow-up process of the semi-conical hole and the hammer head; the dovetail groove is connected with the rotary swaging machine, so that the feeding unit can be conveniently driven to feed the parts and the parts into a machine tool together.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a cross-sectional view a-a of fig. 1.
Detailed Description
The invention will be further described by way of examples with reference to the accompanying drawings:
as shown in fig. 1-2, a 7-shaped swaging clamp device has a main body of a clamp body, wherein the clamp body includes a front clamping portion 1 and a rear connecting portion 2, and an upper end of the clamping portion 1 is connected to a front end of the connecting portion 2, and the whole clamp body is 7-shaped. Whole clamping part 1 is semi-circular, and for making things convenient for clamping part 1 to live the work piece centre gripping, the semicircle taper hole 3 that extends around 1 lower extreme of clamping part is provided with, and for guaranteeing to hold the part steadily in semicircle taper hole 3, the front end diameter of semicircle taper hole 3 is less than the rear end.
In order to facilitate the connection of the entire chuck with the swaging machine and to drive the parts along with the feed unit into the swaging machine, dovetail grooves 4 extending left and right for mounting on the swaging machine are provided at the upper end of the connecting portion 2.
In order to prevent the part from generating clamping marks in the process of moving together with the hammer head after being clamped, inclined planes 3b which are tangent to the arc surfaces 3a and inclined to the corresponding sides are arranged at the root parts of the two ends of the semi-conical hole 3.
Through experiments, the inclined surface 3b is found to be the least prone to generate clamping marks when the included angle between the inclined surface and the vertical line is 20 degrees. The taper of the semicircular conical hole 3 is between 0.45 and 0.65 degrees, and is preferably 0.55 degrees.
In order to conveniently install the dovetail groove 4 on the rotary swaging machine, chamfers 4a are arranged on the left side and the right side of the dovetail groove 4.
In order to ensure that the surface of the part is smooth and has no foreign body feeling when being touched after the part is swaged, the semicircular conical hole 3 is provided with a coating, and polishing treatment is carried out before the coating.
