Abstract

The utility model discloses a workpiece combined clamp of a lathe. The clamp comprises a clamp body, a push tube cooperating with the clamp body to push a workpiece off, and a compression bar cooperating with the clamp body to tightly press the workpiece; the clamp body comprises a base and thimbles which penetrate the base and are symmetrically arranged on two sides of the base; a shaft body is arranged on the base in an extended manner; an outer conical surface is arranged on the shaft body; and the outer conical surface is tangent to a demoulding slope of the workpiece. Therefore, the workpiece is tightly clamped pneumatically, and compared with manual clamp, labor intensity is greatly reduced; and by arranging the outer conical surface to match the workpiece, positioning is precise during operation, and processing quality can be better ensured.

Description

A kind of lathe workpiece built-up jig

Technical field

The utility model relates to lathe processing technique field, especially relates to a kind of lathe workpiece built-up jig.

Background technology

In machining, lathe is a kind of common machining tool.The general working shaft-like of lathe or disc-like rotary part, lathe is in process, and the suffered cutting force of working is larger, in order to guarantee the accuracy of processing parts, also guarantees that operator safety, workpiece need to be fixed by brute force before processing simultaneously.General part blank does not have plane as clamping face, and common lathe workpiece clamping device is three-jaw or four paws.When with three-jaw or four paws fixation workpiece, need to tighten with manpower, in order to ensure enough clamping forces, need to use larger manpower.When workpiece machines, in the time of need to dismantling, need again use manpower dismounting.Lathe operation personnel labor intensity is large.When some workpiece are through roughing, while remaking fine finishining, left allowance is smaller.Owing to being secondary clamping, the clamping workpiece in fine finishining has higher positioning requirements.

Utility model content

In order to solve the deficiencies in the prior art, the purpose of this utility model is to provide a kind of lathe workpiece built-up jig that reduces labour intensity, improves positioning precision.

To achieve these goals, the technical solution adopted in the utility model is:

A kind of lathe workpiece built-up jig, the depression bar that comprises clamp body, coordinates described clamp body to evade the push pipe of workpiece and coordinate described clamp body workpiece pressing, described clamp body comprises base and runs through described base and be symmetrical arranged the thimble of both sides, described base extension arranges an axis body, described axis body arranges a male cone (strobilus masculinus), and the demoulding inclined-plane of described male cone (strobilus masculinus) and workpiece is tangent.

Preferably, the symmetrical both sides of described axis body are provided with the arc groove for described thimble parallel sliding.

Preferably, described push pipe is connected with rotary cylinder.

Preferably, described depression bar is connected with tailstock pneumatic finial.

Preferably, described thimble is "T"-shaped, and under the promotion of push pipe, makes workpiece come off from clamp body 1.

Preferably, described base is the column type of " protruding " state.

Compared with prior art, its beneficial effect is as follows for the utility model:

1. after improving, location gapless, error is little, and crudy is high;

2. adopt pneumatic pinch and rotary cylinder to eject workpiece, workman is light and inloading part is easy.

Mark in figure, 1-fixture, 11-base, 12-thimble, 13-axis body, 14-arc groove, 15-male cone (strobilus masculinus), 2-push pipe, 21-central shaft, 3-depression bar.

The specific embodiment

For ease of the technological means of the utility model and operation are had to understanding and understanding further, below in conjunction with specific embodiment, be elaborated as follows.

As shown in Figure 1, the present embodiment is a kind of lathe workpiece built-up jig, it is characterized in that, the depression bar 3 that comprises clamp body 1, coordinates described clamp body 1 to evade the push pipe 2 of workpiece and coordinate described clamp body 1 workpiece pressing.Wherein, described push pipe 2 is connected with rotary cylinder.Described depression bar 3 is connected with tailstock pneumatic finial.

In conjunction with as shown in Fig. 2,3,4 and 5, described clamp body 1 comprises base 11 and runs through described base 11 and be symmetrical arranged the thimble 12 of both sides, described base 11 extensions arrange an axis body 13, and described axis body 13 arranges a male cone (strobilus masculinus) 15, and described male cone (strobilus masculinus) 15 is tangent with the demoulding inclined-plane of workpiece.

In the present embodiment, the symmetrical both sides of described axis body 13 are provided with the arc groove 14 for described thimble 12 parallel sliding.Described thimble 12 is "T"-shaped, and under the promotion of push pipe 2, makes workpiece come off from clamp body 1.Described base 11 is the column type of " protruding " state.Wherein, a side extension of described push pipe 2 arranges a central shaft 21, so that be connected with rotary cylinder.

For ease of understanding above-described embodiment, the existing brief description of the use procedure by the present embodiment is as follows:

First substantially pack workpiece into clamp body 1; And then by depression bar 3, workpiece is pressed into clamp body 1, and until the male cone (strobilus masculinus) 15 on the axis body 13 of clamp body 1 is tangent with the demoulding inclined-plane on workpiece, thereby completing location, while carrying out machining like this, can not skid; After clamping workpiece, depression bar 3 exits under the drive of tailstock centre, and the rotary cylinder being connected with push pipe 3 forward, push pipe 2 starts to promote the thimble 12 of clamp body 1, make workpiece depart from locating surface, and operator takes off workpiece, push pipe 2 is return again under the drive of rotary cylinder; Finally, next workpiece to be processed is installed on clamp body 1 again, is completed an operation cycle.

The technical solution of the utility model adopts pneumatic pinch workpiece, works and can spend with manually comparing reduction greatly, coordinates by the conical surface is set with workpiece simultaneously, makes work accurate positioning, can better guarantee crudy.

Only preferred embodiment of the present utility model in sum.It should be pointed out that for the person of ordinary skill of the art, not departing under the prerequisite of the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection scope of the present invention.
