Abstract
The utility model discloses a thin-wall part clamp for a lathe, which comprises a body, a connecting seat and a tensioning block, wherein the connecting seat is arranged on the body; the inner end of the body is fixed on a main shaft of the lathe, the inner end of the connecting seat is connected with a main shaft pull rod of the lathe, the connecting seat is movably sleeved in the body and can move back and forth in the body under the driving of the main shaft pull rod of the lathe, and the inner end of the tensioning block is fixed at the outer end of the connecting seat. Because the parts are mounted on the circular boss of the body and accurately positioned, the tensioning blocks fixed on the connecting seat are driven by the lathe spindle pull rod to retract inwards, and the tensioning blocks fixed on the connecting seat move to press the parts so as to fix the parts on the body.
Description
Technical Field
The utility model relates to the field of machining, in particular to a thin-wall part clamp for a lathe.
Background
The fixture is a device for fixing a processing object in a machining process so as to occupy a correct position for processing or detecting. As shown in fig. 1, a circular part 10' is formed by manufacturing a simple fixture composed of a screw 1', a washer 2' and a nut 3', wherein during machining, a chuck clamps the inner end of the screw 1', the part 10' is sleeved on the outer end of the screw 1', the washer 2' is pressed on the outer end of the part 10', the nut 3' is screwed on the screw 1' and presses the washer 2' to fix the part 10', and the conventional clamping mode has the defects of inaccurate positioning and low clamping speed.
Disclosure of Invention
The utility model aims to provide the thin-wall part clamp for the lathe, which has high positioning precision, quick clamping and firm fixation.
In order to achieve the above object, the technical solution of the present utility model is:
the utility model relates to a thin-wall part clamp for a lathe, which comprises a body, a connecting seat and a tensioning block, wherein the connecting seat is arranged on the body; the inner end of the body is fixed on a main shaft of the lathe, the inner end of the connecting seat is connected with a main shaft pull rod of the lathe, the connecting seat is movably sleeved in the body and can move back and forth in the body under the driving of the main shaft pull rod of the lathe, and the inner end of the tensioning block is fixed at the outer end of the connecting seat.
The tensioning block consists of a base and a plurality of clamping claws; the inner ends of the clamping claws are fixed on the base at intervals, and the outer ends of the clamping claws are inclined and outwards opened.
The outer end of the claw is provided with a pressing surface which horizontally extends outwards and is used for pressing the part.
The outer end face of the body is provided with a circular boss, the end face of the circular boss is an axial positioning surface, the outer circular wall of the circular boss is a radial positioning surface, and the circular boss is positioned right below the clamping jaws on the tensioning block; the middle part of the body is provided with more than two through holes so that the connecting seat is connected with the lathe spindle pull rod.
After the scheme is adopted, as the radial clamping device comprises the body, the connecting seat and the tensioning block, the parts are arranged on the circular boss of the body and accurately positioned, the tensioning block fixed on the connecting seat is driven by the spindle pull rod of the lathe to shrink inwards, and the tensioning block fixed on the connecting seat moves to press the parts to fix the parts on the body.
The utility model will be further described with reference to the drawings and the specific examples.

Detailed Description
As shown in fig. 2 and 3, the utility model relates to a thin-wall part clamp for a lathe, which comprises a body 1, a connecting seat 2 and a tensioning block 3.
The inner end of the body 1 is fixed on a main shaft of a lathe, the inner end of the connecting seat 2 is connected with a main shaft pull rod of the lathe, the connecting seat 2 is movably sleeved in the body 1 and can move back and forth in the body 1 under the driving of the main shaft pull rod of the lathe, and the inner end of the tensioning block 3 is fixed at the outer end of the connecting seat 2.
The outer end face of the body 1 is provided with a circular boss 11, the end face of the circular boss 11 is an axial positioning surface 111, the outer circular wall of the circular boss 11 is a radial positioning surface 112, and the circular boss 11 is positioned right below the four clamping claws 32 on the tensioning block 3; the middle part of the body 1 is provided with three through holes 12 so that the connecting seat is connected with a lathe spindle pull rod.
The tensioning block 3 consists of a base 31 and four clamping claws 32; the inner ends of the four clamping claws 32 are fixed on the base 31 at intervals, and the outer ends of the four clamping claws 32 are inclined and outwards opened; the outer end of the jaw 32 has a horizontally outwardly extending compression surface for compressing the part 10.
The working principle of the utility model is as follows:
the part 10 is mounted on the circular boss 11 of the body 1 to be precisely positioned, the tightening block 3 fixed on the connecting seat 2 is driven by the lathe spindle pull rod to be contracted inwards, and the tightening block 3 fixed on the connecting seat 2 moves inwards to press on the part 10 to fix the part 10 on the circular boss 11 of the body.
The foregoing description is only illustrative of the preferred embodiments of the present utility model, and is not intended to limit the scope of the utility model, i.e., the equivalent changes and modifications to the utility model as described in the claims and specification should be considered as falling within the scope of the utility model.
