Abstract

The utility model discloses a machining clamp of a brake ring inner circle face. The machining clamp comprises a chuck and three reversed-ladder-block-shaped movable claws, wherein the chuck is connected with the tail end of a main shaft of a lathe in a fastening mode, and the three reversed-ladder-block-shaped movable claws are arranged on the chuck. The ladder faces of the three movable claws are respectively and fixedly connected with a fan annular block in an integrated mode. The three fan annular blocks are evenly arranged in the angular direction by taking the main axis of the lathe as the center axis. The machining clamp of the brake ring inner circle face has the advantages that deformation does not easily occur when a brake ring is clamped and machined, centering is easier, and the clamping efficiency is high, and the using effect is more ideal.

Description

A kind of trig loop inner headed face machining fixture

Technical field

The utility model belongs to the machining technique field, relates to a kind of trig loop inner headed face machining fixture.

Background technology

Trig loop is the short tubular part, needs the blank that casts out is processed its inside and outside disc with lathe.When processing its inner headed face with lathe, need and to be clamped in the lathe spindle end after trig loop blank circle axle centering.

The universal fixturing of the car tubular part inner circle face of prior art lathe is generally the scroll chuck of hand or dynamical type, its agent structure comprises the chuck 2 that is fastenedly connected with the lathe spindle end, three inverted steps piece shape movable claws 1 that are arranged on chuck 2 as shown in Figure 1.

Adopt the trig loop inner headed face machining fixture of such technology certainly can use, but trig loop is the short tubular part, wall is relatively thin, and the masterpiece that tightens up of movable claw cascaded surface is used on three points on trig loop outside wall surface circumference, and active force is little to be clamped not strongly; Active force may make too greatly again the trig loop distortion; And much smaller than its diameter, when being clamped on movable claw, the centering of its tubular axis line and lathe main axis is difficult to guarantee due to the axial length of pipe, clamps efficient when causing lathe processing inner headed face low, and result of use is desirable not enough.

The utility model content

For overcoming the deficiencies in the prior art, it is a kind of not yielding when clamping trig loop that the utility model provides, and centering is easier, it is high to clamp efficient, and result of use is trig loop inner headed face machining fixture more preferably.

The utility model is to reach the technical scheme that above-mentioned technical purpose adopts to be: a kind of trig loop inner headed face machining fixture comprises the chuck that is fastenedly connected with the lathe spindle end, three inverted steps piece shape movable claws that are arranged on chuck; Equal integrated fan ring block that is fixedly connected with on the cascaded surface of three movable claws; Three the fan ring block centered by the lathe main axis shaft angle to uniform setting.

Described chuck is hydraulic power chuck.

The beneficial effects of the utility model are: due to equal integrated fan ring block that is fixedly connected with on the cascaded surface of three movable claws; Three the fan ring block centered by the lathe main axis shaft angle to uniform setting; When clamping trig loop, the small arc surface of three fan ring blocks presses the periphery of trig loop simultaneously, contact area is large, frictional force is large, stressed evenly, therefore not yielding; Owing to being the periphery that three arc surfaces press trig loop simultaneously, centering is easier; Therefore clamp efficient high, result of use is better.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.Wherein:

Fig. 1 is the schematic diagram of prior art turning attachment;

Fig. 2 is schematic diagram of the present utility model.

Marker number in accompanying drawing is described as follows: movable claw 1, chuck 2, fan ring block 3, trig loop 4

The specific embodiment

Embodiment of the present utility model, as shown in Figure 2, a kind of trig loop inner headed face machining fixture comprises the chuck 2 that is fastenedly connected with the lathe spindle end, three inverted steps piece shape movable claws 1 that are arranged on chuck 2; On the cascaded surface of three movable claws 1 all integrated be fixedly connected with the fan ring block 3; Three the fan ring block 3 centered by the lathe main axis shaft angle to uniform setting.

Described chuck 2 is hydraulic power chucks 2.

Claims

1. a trig loop inner headed face machining fixture, comprise the chuck that is fastenedly connected with the lathe spindle end, three inverted steps piece shape movable claws that are arranged on chuck; It is characterized in that: equal integrated fan ring block that is fixedly connected with on the cascaded surface of three movable claws; Three the fan ring block centered by the lathe main axis shaft angle to uniform setting.

2. a kind of trig loop inner headed face machining fixture according to claim 1, it is characterized in that: described chuck is hydraulic power chuck.
