Abstract
The invention provides a shaft sleeve positioning structure, which is mainly applied to positioning a shaft and a pouring ladle rod. The positioning structure adopts the combination of two basic fastening modes including a clamp-hoop type fastening mode and a pin shaft mode to achieve the shaft sleeve positioning structure which is suitable for working in severe environments, is convenient to mount and maintain, and is suitable for working at high temperature. The structure ensures the safety and the reliability of products and completely achieves the operating requirements.
Description
Technical field
The present invention relates to a kind of shaft sleeve positioning structure, relate in particular to a kind of shaft sleeve positioning structure that is fit to abominable working environment.
Background technology
At casting industry, often change and maintain aluminium liquid casting ladle bar, because work under bad environment, not only operating temperature is spent up to 700, and when real work, aluminium liquid also can cover the junction of two workpiece, work has brought inconvenience to daily maintenance.In addition, because this part is in the working environment of cold and hot variation always, be to guarantee maintenance and change the casting ladle bar, it is bigger that all do in axle and the gap of casting ladle bar.
Localization method in traditional this part has many kinds, and the main method that adopts is as follows:
A. adopt flat key connected mode commonly used in the common mechanical structure, because when real work, casting ladle must be operated under the state of rotating at the state that bears a heavy burden always, when equipment is new, also can use, behind the some months, because under hot environment, flat key is with regard to cisco unity malfunction, the precision of cast loses fully, makes the quality of product not to be guaranteed.
B. also have and adopt the mode of bearing pin that the two is connected, but occurred above-mentioned problem equally, can not deal with problems.
C. a kind of in addition in addition, adopt the form of clamp, this mode is because the relation of working environment, under the effect of expanding with heat and contract with cold, the fastening still instability of axle and bar, the scene that can occur becoming flexible influences real work.
Summary of the invention
Purpose of the present invention provides a kind of shaft sleeve positioning structure exactly in order to address the above problem, adopt this structure can guarantee axle and being fastenedly connected of casting ladle bar.
The object of the present invention is achieved like this:
The invention discloses a kind of shaft sleeve positioning structure, the location that is used for axle and casting ladle bar, described shaft sleeve positioning structure comprises binding clip device, this binding clip device comprises that several clamping screws and an end center of being located at the casting ladle bar have the clamp cover of axis hole, described axle passes the axis hole in the clamp cover, described clamping screw passes the keeper that clamp puts, and described axle is locked.
Described shaft sleeve positioning structure comprises that also one strengthens fixture, described reinforcement fixture comprises pin and nut, described axle radially have a through hole, described clamp be enclosed within the relevant position have a screwed hole with the axle on through hole communicate, the through-hole diameter of described axle is less than the shading diameter in clamp external threading hole, the diameter of described pin head is than the little 0.5mm of through-hole diameter of described axle, length approximates the diameter of described pin, there is one section screw thread at the middle part of described pin, the specification of this screw thread is consistent with the specification of clamp cover upper screwed hole and described nut, the length of screw thread approximates the thickness of described nut and the length sum in described clamp external threading hole, the afterbody of described pin is provided with side's tenon, described pin is fixed in the through hole that clamp put and inserted axle by screw thread, and described nut is threaded onto on the described pin by screw thread, and what holding pin and clamp were overlapped is connected.
The present invention has adopted two kinds of basic fastening means to unite the location structure of use, finally reached and be adapted at working under the adverse circumstances, the convenient installation is convenient to maintenance, be suitable for the shaft sleeve positioning structure of high temperature, this structure has guaranteed the safe and reliable of product and has reached instructions for use fully.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the generalized section of B-B ' direction among Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and embodiments.
Referring to Fig. 1, cooperation is referring to Fig. 2, a kind of shaft sleeve positioning structure of the present invention, the location that is used for axle 1 and casting ladle bar 2, described shaft sleeve positioning structure comprises binding clip device, this binding clip device comprises that 2 clamping screws 4 and an end center of being located at the casting ladle bar have the clamp cover 3 of axis hole, described axle passes the axis hole in the clamp cover 3, described clamping screw 2 passes the keeper on the clamp cover 3, described axle 1 is locked, described shaft sleeve positioning structure comprises that also one strengthens fixture, described reinforcement fixture comprises pin 5 and nut 6, described axle 5 radially have a through hole 11, described clamp cover 3 has a screwed hole 31 and communicates with through hole 11 on spool 1 in the relevant position, through hole 11 diameters of described axle are less than the shading diameter in clamp external threading hole 31, the diameter of described pin 5 heads is than the little 0.5mm of through hole 11 diameters of described axle, length approximates the diameter of described pin 1, there is one section screw thread at the middle part of described pin 1, the specification of this screw thread is consistent with the specification of clamp cover upper screwed hole 31 and described nut 6, the length of screw thread approximates the thickness of described nut 6 and the length sum in described clamp external threading hole 31, the afterbody of described pin 5 is provided with side's tenon, to guarantee when the dismantlement work, under badness, also can operate, described pin 5 by screw thread be fixed in clamp put and insert the axle through hole in, described nut 6 is threaded onto on the described pin 5 by screw thread, and holding pin 5 is connected with clamp cover 3.
Above embodiment is only for the usefulness that the present invention is described, but not limitation of the present invention, person skilled in the relevant technique, under the situation that does not break away from the spirit and scope of the present invention, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present invention, should be limited by each claim.
