Abstract
The utility model discloses a special fixture for outer diameter turning by means of inner bore positioning. The special fixture for the outer diameter turning by means of the inner bore positioning comprises a flange and a locking part, wherein the locking part is arranged in the center of the flange, the fixture is fixed on a numerically-controlled machine tool through the flange, a workpiece with an inner bore is sleeved into the locking part, the locking part tightly clamps the workpiece through the inner bore after the locking part expands outwards, an inner bore positioning method is adopted, and the workpiece is clamped and loosened through inward expansion and then is turned. According to the special fixture for the outer diameter turning by means of the inner bore positioning, a clamping button is arranged inside the improved special purpose machine tool, a pull rod and a locking rod which are in threaded connection are pulled backwards to enable a clamping sleeve to expand outwards to further tightly clamp the workpiece, and then the outer diameter turning can be carried out directly. After the outer diameter is well turned, the pull rod and the locking rod which are in connection are pushed forwards through a release button on a functional interface of the special purpose machine tool, and then the clamping sleeve is in a relaxed state and the workpiece can be taken out easily.
Description
Technical field
The utility model relates to for endoporus location turning external diameter special fixture.
Background technology
Be used for mechanical five metals, electric tool parts, sewing machine parts, auto parts and components etc.Locate the anchor clamps of turning external diameter at present with endoporus, a lot of chucks that adopt, clamp the turning external diameter by a pad and spiral, install and remove all very inconveniently, directly had influence on product at the yield on the same day, wasted a lot of times greatly, its production efficiency can't be improved, and mounting or dismounting time, need manual intervention, there is certain potential safety hazard.
Summary of the invention
At above-mentioned be exactly defective, the utility model proposes for endoporus location turning external diameter special fixture.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows:
Be used for endoporus location turning external diameter special fixture, comprise flange, tight lock part, described tight lock part is located at described flange central authorities, and described anchor clamps are fixed on the Digit Control Machine Tool by described flange, the workpiece that has endoporus is inserted in described tight lock part, and described tight lock part expands the back outward by the endoporus clamping work pieces.
Further, described tight lock part comprises check lock lever, gripping sleeve, and described gripping sleeve hollow is horn-like at the head end of described gripping sleeve inwall, and described check lock lever passes described gripping sleeve, and the afterbody outer wall of described check lock lever is close to described gripping sleeve inwall.
Further, described tight lock part also comprises pull bar, and the head of described check lock lever is provided with internal thread, and described pull bar is provided with the external screw thread with described screw-internal thread fit.
Further, described tight lock part is fixed on the described flange by nut.
The beneficial effects of the utility model are: employing be with endoporus location, expand to clamp and relaxation products by interior, be that it carries out turning processing.By clamping button in the special purpose machine tool of the transformation of the way, thread connection pull bar and the past post-tensioning of check lock lever together, gripping sleeve is expanded outward, play the effect that clamps product, direct turning external diameter with that is after turning is good, the button that loosens by special purpose machine tool merits and demerits interface, the pull bar and the check lock lever that are linked together are pushed away forward, and section so just can easily be taken out product between king's gripping sleeve just was in and loosens like this.The anchor clamps contrast that clamps with bolt and loosen had obviously improved product efficiency in the past.Also greatly reduce employee's working strength, load and unload owing to do not need to stretch into lathe, eliminated potential safety hazard of the prior art.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structure chart of the utility model flange.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described further.
As depicted in figs. 1 and 2: the utility model provides a kind of and is used for mechanical five metals, electric tool parts, sewing machine parts, the special fixture of auto parts and components for processing.Comprise flange 6, tight lock part, described flange 6 central openings, described tight lock part is located at described flange 6 central authorities, described clamping section is fixed on the described flange by nut 1 in general, described anchor clamps are fixed on the Digit Control Machine Tool by described flange 6, the workpiece 5 that has endoporus is inserted in described tight lock part, and described tight lock part expands the back outward by the endoporus clamping work pieces.As preferably, described tight lock part comprises check lock lever 2, gripping sleeve 3, and described gripping sleeve 3 hollows are horn-like at the head end of described gripping sleeve 3 inwalls, and described check lock lever 2 passes described gripping sleeve 3, and the afterbody outer wall of described check lock lever 2 is close to described gripping sleeve 3 inwalls.When check lock lever 2 inwardly stretched into, its afterbody outer wall compressed described gripping sleeve 3 inwalls, made described gripping sleeve 3 outwards strut, thus the internal diameter of gripping sleeve 3 clamping work pieces.The control of Digit Control Machine Tool for convenience, be provided with internal thread at check lock lever 2 head ends, the pull bar 4 of Digit Control Machine Tool is provided with the external screw thread with described screw-internal thread fit, pass through screw thread rotation, pull bar 4 is connected with described check lock lever 2, as long as the control personnel are the pull bar of control Digit Control Machine Tool like this, the operation that can stretch and discharge check lock lever 2, thereby control clamping and releasing workpiece 5.
What the utility model adopted is with the endoporus location, expands to clamp and relaxation products by interior, is that it carries out turning processing.By clamping button in the special purpose machine tool of the transformation of the way, thread connection pull bar and the past post-tensioning of check lock lever together, gripping sleeve is expanded outward, play the effect that clamps product, direct turning external diameter with that is after turning is good, the button that loosens by special purpose machine tool merits and demerits interface, the pull bar and the check lock lever that are linked together are pushed away forward, and section so just can easily be taken out product between king's gripping sleeve just was in and loosens like this.The anchor clamps contrast that clamps with bolt and loosen had obviously improved product efficiency in the past.Also greatly reduce employee's working strength.
The above only is preferred embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model design; can also make some improvements and modifications, these improvements and modifications also should be considered as in the utility model protection domain.
