Abstract
The utility model discloses a tensioning mandrel which comprises a mandrel body and a pressure adjusting bolt. The mandrel body is provided with a cavity, a liquid medium is filled in the cavity, a hydraulic elastic tensioning sleeve is arranged outside the mandrel body, one opening end of the mandrel body is provided with a plunger, the mandrel body is provided with a top hole communicated with the cavity, the pressure adjusting bolt is connected with the top hole and is sealed through a seal ring, and a retainer ring for fixing the seal ring is arranged on the pressure adjusting bolt. The pressure in the cavity can be adjusted by rotating the pressure adjusting bolt, accordingly the liquid medium is expanded to swell the hydraulic elastic tensioning sleeve to tension an inner hole of a processed product. Therefore, the purpose of eliminating gaps is achieved, unstable transmission between the mandrel and the processed product is reduced, and low-frequency noise produced by eccentricity is eliminated.
Description
Technical field
The utility model belongs to the technical field of workpiece clamping device, relates in particular to a kind of tensioner axle.
Background technology
At present, known gear hobbing anchor clamps structure is that gear hobbing axle and nut are formed by connecting.With the product to be processed axle of packing into, compress with nut.But all can there be certain machining tolerance in the gear hobbing axle when grinding cylindrical and product to be processed processing endoporus, causes to have the gap between gear hobbing axle and the product to be processed and cause gear hobbing eccentric, causes transmission not steady, and is prone to produce low-frequency noise.
The utility model content
The technical problem that the utility model will solve provides a kind of tensioner axle, and the fluidity medium of extruding in the cavity expands it to rise big the hydroelastic system ringfeder and with product to be processed endoporus tensioner, and reaches the purpose of eliminating the gap.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: a kind of tensioner axle comprises axle body and regulator bolts; Have cavity in the said axle body, be filled with liquid medium in the cavity, the axle body is provided with the hydroelastic system ringfeder outward; One end of axle body openings is provided with plunger; Have with cavity on the axle body and be communicated with center hole, regulator bolts is connected with center hole and through the sealing ring sealing, regulator bolts is provided with the back-up ring that is used for fixing sealing ring.
Compared with prior art; The advantage of the utility model is: the rotation regulator bolts is the pressure in the scalable cavity; Thereby make the fluidity media expansion rise the hydroelastic system ringfeder big and with product to be processed endoporus tensioner; And reaching the purpose of eliminating the gap, the transmission that has reduced between axle and the product to be processed is not steady, has eliminated the low-frequency noise that produces because of eccentric.
Further, also be provided with the adjusting nut on the said regulator bolts, locking positioning is carried out in the outside of regulator bolts.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model technical scheme is further specified:
Fig. 1 is the front view of a kind of embodiment of the utility model tensioner axle;
Fig. 2 is the left view of a kind of embodiment of the utility model tensioner axle.
The specific embodiment
As depicted in figs. 1 and 2, a kind of tensioner axle of the utility model comprises axle body 1 and regulator bolts 2; Have cavity 3 in the said axle body 1, be filled with liquid medium in the cavity 3, the axle body 1 outer hydroelastic system ringfeder 4 that is provided with; One end of axle body 1 opening is provided with plunger 5; Have on the axle body 1 with cavity 3 and be communicated with center hole, regulator bolts 2 is connected with center hole and through sealing ring 6 sealings, regulator bolts 2 is provided with the back-up ring 7 that is used for fixing sealing ring 6.Also be provided with on the said regulator bolts 2 and regulate nut 8, locking positioning is carried out in the outside of regulator bolts 2.
The advantage of the utility model is: rotation regulator bolts 2 is the pressure in the scalable cavity 3; Thereby make the fluidity media expansion rise hydroelastic system ringfeder 4 big and with product to be processed endoporus tensioner; And reach the purpose of eliminating the gap; The transmission that has reduced between axle and the product to be processed is not steady, has eliminated the low-frequency noise that produces because of eccentric.
The process of the utility model is: regulator bolts 2, adjusting nut 8, sealing ring 6, back-up ring 7 are seated, then plunger 5 are extracted, liquid medium is injected in the cavity 3, at last plunger 5 is seated back correct grinding outer rim.
For a person skilled in the art; Under the prerequisite that does not break away from the utility model structure; Can also make some distortion and improvement, these also should be regarded as the protection domain of the utility model, and these can not influence effect and practical applicability that the utility model is implemented.
Claims (2)
1. a tensioner axle comprises the axle body, it is characterized in that: also comprise regulator bolts; Have cavity in the said axle body, be filled with liquid medium in the cavity, the axle body is provided with the hydroelastic system ringfeder outward; One end of axle body openings is provided with plunger; Have with cavity on the axle body and be communicated with center hole, regulator bolts is connected with center hole and through the sealing ring sealing, regulator bolts is provided with the back-up ring that is used for fixing sealing ring.
2. tensioner axle as claimed in claim 1 is characterized in that: also be provided with the adjusting nut on the said regulator bolts.
