Abstract
A slip embedded tensioner comprises an expansion screw, a guide pipe, an adjusting nut, a power takeoff nut, a supporting flange, two opposed slips and a tensioning rubber ring. The slip embedded tensioner is characterized in that the two opposed slips are sleeved at one end of the expansion screw in opposite manner, the tensioning rubber ring is mounted on the outer side of the opposed slips, the other end of the expansion screw penetrates through the guide pipe and then is screwed into the adjusting nut, and the guide pipe penetrates into the supporting flange and then is screwed into the power takeoff nut. Compared with the prior art, the slip embedded tensioner has the advantages of high reliability, simplicity in manufacturing and convenience in use. According to the conical surface expanding principle, the slips outside a cone are expanded to be combined with the inner wall of a spacer bush, so that the spacer bush can be detached by the aid of friction. In addition, the slip embedded tensioner has the advantages of being capable of adapting to spacer bushes in different sizes by replacing slips of different outer diameters.
Description
One, technical field
The utility model relates to a kind of novel chest expander of repair of machine industry, is specifically related to a kind of built-in slips chest expander.
Two, background technology
In the repair procedures of mechanical industry, the reliability of chest expander and operability have played very important effect to repairing efficient.Traditional pawl formula or coupling type chest expander are only applicable to the bigger parts of appearance and size, can't use the dismounting of the less spacer of size.
Three, utility model content
The purpose of this utility model is exactly the defective that exists at prior art, and a kind of reliable operation, built-in slips chest expander easy to use are provided.
Its technical scheme is: comprise dilating screw, guiding tube, adjustment nut, power taking nut, protruding of support, opposed slips and tensioner cushion rubber.Two opposed slips are sleeved on an end of dilating screw relatively, and the tensioner cushion rubber is installed in the outside of opposed slips; The dilating screw other end screws in the adjustment nut after passing guiding tube, and guiding tube screws in the power taking nut after penetrating and supporting protruding.
Wherein, an end of described dilating screw is the centrum shape, and opposed slip sleeve is contained in centrum shape end, and the other end is cubic shape structure, and its periphery, top is provided with screw thread, and this screw thread is meshed with the adjustment nut.Described guiding tube is a tubular structure, and the one end is provided with outer lug boss in the form of annular discs, and the other end is provided with six side's shape structures, and the guiding tube periphery is provided with screw thread, and this screw thread is meshed with the power taking nut.Protruding of described support is a jar shape formula structure, and the top is provided with outer lug boss in the form of annular discs, and this boss nose-circle disk center is provided with via hole, supports protruding side and is arranged with two notches.Described opposed slips is the structure of two semi-annular shapes, and its outer surface also can snap in the guiding tube into a cone shape, and opposed slips is provided with aprons slot outward.
The utility model has the reliability height compared with prior art, makes simply advantage easy to use.Utilize the extension Principle of the conical surface, make the slips expansion of cone outside and spacer inwall in conjunction with after, rely on frictional force, the dismounting spacer also has and changes the advantage that the various outer diameter slips adapts to the spacer size.
Four, description of drawings
Accompanying drawing is the structural representation of a kind of embodiment of the utility model.
Five, the specific embodiment
Referring to accompanying drawing, a kind of built-in slips chest expander comprises dilating screw 1, guiding tube 2, adjustment nut 3, power taking nut 4, protruding 5 of support, opposed slips 6 and tensioner cushion rubber 7.Two opposed slips 6 are sleeved on an end of dilating screw 1 relatively, and tensioner cushion rubber 7 is installed in the outside of opposed slips 6; Dilating screw 1 other end passes guiding tube 2 backs and screws in adjustment nut 3, and guiding tube 2 screws in power taking nut 4 after penetrating and supporting protruding 5.One end of dilating screw 1 is the centrum shape, and opposed slips 6 is sleeved on centrum shape end, and the other end is cubic shape structure, and its periphery, top is provided with screw thread, and this screw thread is meshed with adjustment nut 3.Guiding tube 2 is a tubular structure, and the one end is provided with outer lug boss in the form of annular discs, and the other end is provided with six side's shape structures, and guiding tube 2 peripheries are provided with screw thread, and this screw thread is meshed with power taking nut 4.Supporting protruding 5 is a jar shape formula structure, and the top is provided with outer lug boss in the form of annular discs, and this boss nose-circle disk center is provided with via hole, supports protruding 5 side and is arranged with two notches.Opposed slips 6 is the structure of two semi-annular shapes, and its outer surface also can snap in the guiding tube 2 into a cone shape, the opposed slips 6 outer aprons slots that are provided with.
When specifically use at the scene, at first tensioner cushion rubber 7 is inserted in opposed slips 6 aprons slots, whole then through on dilating screw 1 conical surface, guiding pipe box 2 is gone into dilating screw 1, guiding tube 2 outer faces and the 6 inner face combinations of opposed slips, be inserted in guiding tube 2 for protruding 5 supporting, power taking nut 4 is installed on the screw thread of guiding tube 2, adjusts nut 3 and is installed on the screw thread of dilating screw 1.After assembling finishes, opposed slips 6 directions are inserted spacer inwall rational position, and fastening adjustment nut 3 rises outside opposed slips 6 and spacer inwall knot and tight, adjusts power taking nut 4 positions along screw thread, when with support contact for protruding 5 after, move to support protruding 5 position, the body end face at itself and spacer place is contacted, continue fastening power taking nut 4 then, by supporting the notch on protruding 5, the action situation of spacer is got by observation post, and is loosening up to spacer, takes out spacer.Six sides of the four directions of dilating screw 1 one ends and guiding tube 2 one ends, its effect is when preventing fastening adjustment nut 3 or power taking nut 4, the body rotation, adding opposite force with spanner can eliminate.
When the spacer size has different the variation, can change the dilating screw 1 and the opposed slips 6 of different size, play multiduty purpose.
