Abstract
The invention provides an automatic positioning broaching device which comprises a body, a positioning base and a positioning plate. The body is provided with a hemispheric pit, a pit through hole is formed in the bottom of the pit, the pit through hole is coaxial with the center of the pit, the positioning base is arranged inside the pit, the upper surface and the lower surface of the positioning base are planes, the side surface of the positioning base is matched with the surface of the pit, the positioning base is provided with a positioning base through hole, the positioning base through hole is coaxial with the pit through hole, the positioning plate is in a long cylinder flange shape, the flange cylinder portion penetrates through the positioning base through hole, the body is exposed out of the lower end of the flange cylinder portion, a certain gap is reserved between the flange long cylinder portion and the edge of the pit of the body, and the upper base diameter of the positioning plate is smaller than the upper surface diameter of the positioning base. The automatic positioning broaching device has the advantages that by means of the technical scheme, a workpiece can be adjusted along with the external force direction when forced by the external force during broaching, the positioning face of the workpiece is made to be perpendicular to the broaching direction of a broach, and a tool can meet the requirement of precision of the workpiece more conveniently.
Description
Technical field
The invention belongs to a kind of frock of machined part, especially relate to a kind of automatic location boring device.
Background technology
In synchronizer gear sleeve, tooth hub processing internal spline operation, in upper operation processing hole with end face run-out large or positioning disk and worktable for broaching machine out of plumb, easily cause the workpiece broaching tool to broach inhomogeneous, make the inside workpiece damage.
Content of the present invention
For solving the problems of the technologies described above, the invention provides a kind of automatic location boring device, comprise body (1), positioning seat (3), positioning disk (2), described body (1) has a hemispherical dimples, pit bottom has a pit through hole, described pit through hole and pit center of circle concentric; There is a positioning seat (3) described pit inside, and described positioning seat upper surface and lower surface are plane, and side surface is complementary with pit surface, described positioning seat have the positioning seat through hole and with pit through hole concentric; Described positioning disk (2) is long cylinder flange shape, flange long cylinder part is passed and body is exposed in lower end from the positioning seat through hole, flange long cylinder part has certain interval with the pit edge of body, and positioning disk (2) upper bed-plate diameter is less than positioning seat (3) upper surface diameter.
The further described back-up ring that also comprises, described back-up ring screws and is connected by screw thread with positioning disk long cylinder lower end, and back-up ring is connected with body by spring.
Further described positioning seat (3) lower surface and pit bottom through hole have certain interval
Advantage and good effect that the present invention has are: owing to adopting technique scheme, when being subjected to external force, workpiece can automatically with external force direction, adjust when broaching, make workpiece locating surface and broaching tool broaching direction keep vertical effect, make frock can reach workpiece accuracy require convenient.

In figure:
1, body 2, positioning disk 3, positioning seat 4, back-up ring 5, spring
The specific embodiment
As shown in Figure 1, the present invention locates a kind of automatic location of boring device boring device automatically, comprise body (1), positioning seat (3), positioning disk (2), described body (1) has a hemispherical dimples, pit bottom has a pit through hole, described pit through hole and pit center of circle concentric; There is a positioning seat (3) described pit inside, and described positioning seat upper surface and lower surface are plane, and side surface is complementary with pit surface, described positioning seat have the positioning seat through hole and with pit through hole concentric; Described positioning disk (2) passes and body is exposed in lower end from the positioning seat through hole for long cylinder flange shape flange long cylinder part, flange long cylinder part has certain interval with the pit edge of body, and positioning disk (2) upper bed-plate diameter is less than positioning seat (3) upper surface diameter.
The further described back-up ring that also comprises, described back-up ring screws and is connected by screw thread with positioning disk long cylinder lower end, and back-up ring is connected with body by spring.Spring can make positioning disk get back to original position, and is more convenient to operate.
Further described positioning seat (3) lower surface and pit bottom through hole have certain interval.Make positioning seat bottom and pit bottom have a segment distance, can make positioning seat that mobile space is arranged, unlikelyly cause mobile excessive and the danger that comes off is arranged.
The assembling of this device and working method:
Be bolted on lathe automatically locating the boring device body, workpiece is placed on upper bed-plate on positioning disk, broaching tool passes workpiece and positioning disk, then broach, when being subjected to external force, positioning seat can automatically with external force direction, adjust, guarantee the vertical of workpiece locating surface and broaching tool broaching direction, after broaching and completing, spring is because restoring force resets.
Claims (3)
1. automatically locate boring device for one kind, it is characterized in that: comprise body (1), positioning seat (3), positioning disk (2), described body (1) has a hemispherical dimples, and pit bottom has a pit through hole, described pit through hole and pit centres concentric; There is a positioning seat (3) described pit inside, and described positioning seat upper surface and lower surface are plane, and side surface is complementary with pit surface, described positioning seat have the positioning seat through hole and with pit through hole concentric; Described positioning disk (2) is long cylinder flange shape, flange long cylinder part is passed and body is exposed in lower end from the positioning seat through hole, flange long cylinder part has certain interval with the pit edge of body, and positioning disk (2) upper bed-plate diameter is less than positioning seat (3) upper surface diameter.
