Technical Field
The utility model relates to an anchor clamps, especially a cold crowded pinion finish turning anchor clamps.
Background
The gear shaft is a precise transmission part with a special structure, the traditional manufacturing process comprises blank making, turning, gear making, spline hobbing, heat treatment and grinding, and the sequence of the working procedures comprises the steps of firstly forming a reference and then processing a tooth shape. The cold extrusion gear shaft firstly extrudes the gear shape and then processes the reference and other surfaces. The structural design of the gear shaft reference surface clamp is different from that of a conventional clamp. Currently, there are no fixtures for cold-extrusion of gear shaft datum faces and other surface treatments.

The to-be-solved technical problem of the utility model is: overcomes the defects in the prior art and provides a finish turning clamp for a cold extrusion gear shaft.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a cold crowded tooth axle finish turning anchor clamps, including first base, the one end of first base is connected with the connection pad of fixing on the workstation, its other end is connected with the second base, the second base still is connected with the third base of frustum structure, the through-hole has been seted up along the axial in the middle part of the third base, be provided with the profile of tooth elastic sleeve on the through-hole inner wall, the terminal outside of profile of tooth elastic sleeve is equipped with first adapter sleeve, be provided with the bolt that runs through behind the second base and be connected with the third adapter sleeve on the first adapter sleeve, the third adapter sleeve sets up at first base inner wall, the bolt is equipped with the second adapter sleeve outward, second base middle part has the arch of stretching into in the through-hole, bellied tip with wait to correct tooth axle or correction piece one end cooperation.
Furthermore, the tooth-shaped elastic sleeve is of an internal tooth-shaped structure, and the tooth-shaped structure is T-shaped.
Furthermore, the first base is provided with a step hole, the cross section of the second base is in a cross shape, the middle part of the second base is provided with two bulges along two axial directions, one bulge extends into the step hole of the first base, and the other bulge extends into the through hole of the third base.
Furthermore, the length of the protrusion extending into the first base step hole is smaller than that of the protrusion extending into the third base through hole.
The utility model has the advantages that: the fixture of the utility model is convenient to adjust and can be changed quickly, high-efficiency production is realized, the fixture core fixing precision is high, and the positioning is accurate; the correcting piece corrects the clamp after the clamp is installed, and meanwhile, the repeated positioning accuracy of the clamp can be verified.
Drawings
The present invention will be further described with reference to the accompanying drawings and embodiments.
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural diagram of the utility model after the correction member is installed.
In the figure: 1. the connecting structure comprises a first base, 2 connecting discs, 3 a second base, 4 a third base, 5 a tooth-shaped elastic sleeve, 6 a first connecting sleeve, 7 a third connecting sleeve, 8 a bolt and 9 a second connecting sleeve.
Detailed Description
The invention will now be further described with reference to the accompanying drawings. The drawings are simplified schematic diagrams only illustrating the basic structure of the present invention in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1, the finish turning fixture for the cold extrusion gear shaft of the embodiment includes a first base 1, one end of the first base 1 is connected with a connection pad 2 fixed on a workbench, the other end of the first base is connected with a second base 3, the second base 3 is further connected with a third base 4 of a frustum structure, a through hole is axially formed in the middle of the third base 4, a tooth-shaped elastic sleeve 5 is arranged on the inner wall of the through hole, a first connection sleeve 6 is arranged on the outer side of the tail end of the tooth-shaped elastic sleeve 5, a bolt 8 penetrating through the second base 3 and connected with the third connection sleeve 7 is arranged on the first connection sleeve 6, the third connection sleeve 7 is arranged on the inner wall of the first base 1, a second connection sleeve 9 is arranged outside the bolt 8, a protrusion extending into the through hole is formed in the middle of the second base 3, and the end of the protrusion is matched with one end.
In the present embodiment, the toothed elastic sleeve 5 has an internal tooth structure, and the tooth structure is T-shaped.
In this embodiment, the first base 1 is provided with a step hole, the cross section of the second base 3 is cross-shaped, the middle part of the second base 3 is provided with two protrusions along two axial directions, one protrusion extends into the step hole of the first base 1, and the other protrusion extends into the through hole of the third base 4. The length of the bulge extending into the step hole of the first base 1 is less than that of the bulge extending into the through hole of the third base 4.
