Abstract
The utility model discloses a uniform stress type tensioning column and nut connecting structure, which comprises a tensioning column, a tensioning column nut, a front plate and a master cylinder seat, wherein the front plate matches with the master cylinder seat. The uniform stress type tensioning column and nut connecting structure is characterized in that the tensioning column nut adopts an embedded design, the front end of the tensioning column nut is provided with an inclined surface which matches with the front plate and the master cylinder seat, and thread of the tensioning column and thread of the tensioning column nut are trapezoidal thread. Compared with the traditional design, the uniform stress type tensioning column and nut connecting structure is less in modification, effectively reduces breakage rate of the tensioning column while reducing modifying cost, not only saves economic loss caused by breakage of the tensioning column, but also provides better guarantee to production efficiency, and accordingly has fine popularization value.
Description
Technical field
The utility model relates to the extruder technical field, relates to a kind of tension post and nut mounting connection structure that is used for the aluminium alloy extrusions extruder in particular.
Background technology
The tension post is one of frame structure core component of extruder, is the skeleton of entire machine.Because the stress influence that the tension column length phase produced when being squeezed, the tension post has the possibility of fracture, and in case fracture will cause very high maintenance cost, so the production technology and the installation adjustment of tension post all had very harsh requirement.At present, though the production technology of tension post reaches its maturity, the common planar end surface nut that is used for locking tension post two ends is little for the stress influence aspect effect that reduces the tension post, and the tension post still faces the possibility of fracture.
Summary of the invention
The purpose of this utility model is exactly provide for the deficiency that solves prior art a kind of not only simple and practical, and even stressed formula tension post and the nut syndeton very little to the change of machine.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of even stressed formula tension post and nut syndeton, comprise tension post, tension post nut and supporting header board and master cylinder seat, it is characterized in that: described tension post nut adopts embedded design, the front end of tension post nut is provided with the inclined-plane that cooperates with header board and master cylinder seat, and the screw thread of tension post and tension post nut is trapezoidal thread.
As further specifying of such scheme, the end of described header board and master cylinder seat is provided with caulking groove, tension post nut front end inclined-plane is embedded in the caulking groove, and tension post nut front end face contacts with the end face of header board or master cylinder seat to pin the tension post, and tension post nut back end face is installed the nut anti-looseness plate.
The embedded part of described tension post nut is thin more the closer to front end.
The two ends of described tension post are respectively arranged with tension post nut.
The beneficial effect that the utility model adopts above-mentioned solution to reach is:
The utility model adopts the road number of Embedded tension post nut design having increased screw thread, makes the bigger contact area of acquisition between tension post nut and the tension post; In addition, because embedded part is thin more the closer to front end, cooperate the trapezoidal thread design again, make when the stressed generation elastic deformation of tension post, embedded part screw thread contact point foremost can produce outside potential energy, stressed center of gravity can not moved by not having no progeny foremost, reach evenly stressed state of whole tension post nut at last, be different from the design that in the past the stressed center of gravity of planar end surface nut concentrates on former roads screw thread greatly, the stress that is produced in the time of so just effectively disperseing the stressed generation elastic deformation of tension post makes the tension post be not easy fracture.

The specific embodiment
As Fig. 1～shown in Figure 6, a kind of even stressed formula tension post of the utility model and nut syndeton, comprise tension post 1, tension post nut 2 and supporting header board 4 and master cylinder seat 5, tension post nut is installed on tension post 1 two ends, the front end of tension post nut is provided with the inclined-plane 7 that cooperates with header board 4 and master cylinder seat 5, tension post nut 2 front ends are embedded into 5 li of header board 4 or master cylinder seats, the embedded part of tension post nut is thin more the closer to front end, front end face contacts with the end face of header board or master cylinder seat to pin tension post 1, rear end face is provided with screw 6, and be installed with nut anti-looseness plate 3 by the screw on the screw 6, get loose to prevent nut; Screw thread between tension post and the tension post nut all is a trapezoidal thread 8.
In the use, when the stressed generation elastic deformation of tension post, tension post nut embedded part screw thread contact point foremost can produce outside potential energy, and stressed center of gravity can not moved by not having no progeny foremost, reaches evenly stressed state of whole tension post nut at last.
Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
