Description
Technical field
The utility model belongs to Machine Tool Fixture Design technical field, relates to a kind of thin-walled tubbiness part rigidity stiffening device.
Background technology
Thin-walled tubbiness machine adds part owing to existing the situation that wall thickness is thinner, in processing and clamping process, easily there is compressing distortion and machining deformation, outward appearance and the quality of part are had a strong impact on, qualification rate is low, for solution machine adds these problems that occur in process, need to adopt corresponding means to strengthen the rigidity at part thin-walled place.
Summary of the invention
The object of the invention is: propose one and be exclusively used in thin-walled tubbiness part rigidity stiffening device.
Technical scheme of the present invention is: a kind of thin-walled tubbiness part rigidity stiffening device, it is characterized in that, this device comprises collet 1, compact heap 1, compact heap 23, expansion sleeve 4 and screw 5, compact heap 1 and compact heap 23 are positioned over respectively the inner two ends of collet 1, collet 1 is positioned over expansion sleeve 4 inside, described screw 5 is through compact heap 1 and compact heap 23, and nut 6 is loaded onto in screw 5 terminations.
Described collet 1 is tubular structure, inside pipe wall mid portion consistency of thickness, from mid portion tapered attenuation gradually to inside pipe wall two ends, on tube wall, have the staggered axial groove that is uniformly distributed to centre from pipe two ends, the length of groove is at least 1/2nd of overall length, and axial groove is the groove from pipe outer wall to inwall.
Described expansion sleeve 4 is also tubular structure, outer wall is consistent with the interior shape of part 1, inwall is consistent with the outer wall of collet 1, on tube wall, have the staggered axial groove that is uniformly distributed to centre from pipe two ends, the length of groove is at least 2/3rds of overall length, and axial groove is the groove from pipe outer wall to inwall.
Compact heap 1 and compact heap 23 are the Tapered Cup coordinating with collet 1 two ends inner wall shape.
Advantage of the present invention is: by adopting the applying mechanically of two kinds of spring structures of collet and expansion sleeve, can omnibearingly carry out comprehensive rigidity reinforcement to part inwall.

Detailed description of the invention
Below the utility model is described in further details.
A kind of thin-walled tubbiness part rigidity stiffening device, this device comprises collet 1, compact heap 1, compact heap 23, expansion sleeve 4, screw 5 and nut 6, compact heap 1 and compact heap 23 are positioned over respectively the inner two ends of collet 1, and collet 1 is positioned over expansion sleeve 4 inside.Described screw 5 is through compact heap 1 and compact heap 23, and nut 6 is loaded onto in screw 5 terminations.
Described collet 1 is tubular structure, inside pipe wall mid portion consistency of thickness, from mid portion tapered attenuation gradually to inside pipe wall two ends, on tube wall, have the staggered axial groove that is uniformly distributed to centre from pipe two ends, the length of groove is at least 1/2nd of overall length, axial groove is the groove from pipe outer wall to inwall, and the width of axial groove is the 1%-3% of pipe outer diameter.
Described expansion sleeve 4 is also tubular structure, outer wall is consistent with the interior shape of part 1, inwall is consistent with the outer wall of collet 1, on tube wall, have the staggered axial groove that is uniformly distributed to centre from pipe two ends, the length of groove is at least 2/3rds of overall length, axial groove is the groove from pipe outer wall to inwall, and the width of axial groove is the 1%-3% of pipe outer diameter.
Compact heap 1 and compact heap 23 are the Tapered Cup coordinating with collet 1 two ends inner wall shape.
The course of work of the present utility model is as follows:
Compact heap 1 and compact heap 23 are positioned over respectively the both sides of collet 1, and middle through screw 5, screw 5 termination mounting nuts 6, on the whole outer wall that is enclosed within collet 1 of expansion sleeve 4.When actual use, compact heap 1 and compact heap 23, under the effect of screw 5 and nut 6, can produce inside horizontal movement, and then two ends that can distending collet 1, and horizontal movement amount is larger, and the yardstick of distending is just larger.After collet 1 two ends distending, directly act on cover expansion sleeve 4 outside, expansion sleeve 4 can make the two ends distending of collet 1 be converted into omnibearing entirety circle distending, and expansion sleeve 4 outer walls are directly pressed against workpiece 7 inner sides, thereby reach rigidity booster action.
