Abstract
The utility model discloses a novel guide pillar, including interior cylinder and overcoat, evenly be provided with a plurality of recesses on the outer wall of interior cylinder, the recess bottom is provided with the spring, spring one end outwards is provided with the step shaft, the staff of step shaft outwards, the center department of overcoat is provided with the centre bore, the centre bore matees with interior cylinder, in the interior cylinder insertible centre bore, be provided with the shrinkage pool that matches with the step shaft staff on the inner wall of centre bore. The utility model discloses an interior cylinder and overcoat at the during operation, produce the friction between overcoat and the guide pin bushing, when the surface damage, only need to change the overcoat can, practice thrift and does not waste.
Description
Technical field
The utility model relates to a kind of novel guide pillar, belongs to mold parts field.
Background technology
During Design of Dies, need on mould, arrange multiple guide pillars and bushes, these guide pillars and bushes one_to_one corresponding also cooperatively interact, so that when matched moulds, ensure its precision; Guide pillars and bushes is all made of metal, and operationally, the friction between guide pillars and bushes is frequent, is easy to damage guide post surface.Because existing guide pillar is integrative-structure substantially, if damaged surfaces, needing integral replacing, is very waste.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of novel guide pillar.
In order to achieve the above object, the technical scheme that the utility model adopts is:
A kind of novel guide pillar, comprise inner cylinder and overcoat, the outer wall of described inner cylinder is evenly provided with some grooves, described bottom portion of groove is provided with spring, and described spring one end is outwardly provided with multidiameter, and the little axle of described multidiameter outwardly, the center of described overcoat is provided with centre bore, described centre bore mates with inner cylinder, and described inner cylinder can embed in centre bore, the inwall of described centre bore is provided with the shrinkage pool that axle little of multidiameter mates.
Described inner cylinder is cylinder, and described overcoat is hollow circular cylinder.
Also comprise upper cover plate and lower cover, described inner cylinder is consistent with the length of overcoat, when inner cylinder embeds the centre bore of overcoat, upper cover plate and lower cover lay respectively at two ends, and by securing member, the top of upper cover plate, inner cylinder and the top of overcoat are tightened together, by securing member, the bottom of lower cover, inner cylinder and the bottom of overcoat are tightened together.
Described upper cover plate and lower cover are plectane, and radius is consistent with the outer radius of overcoat.
Also comprise upper cover plate and lower cover, the center of described upper cover plate and lower cover is provided with screw, the length of described inner cylinder is greater than the length of overcoat, when inner cylinder embeds the centre bore of overcoat, centre bore is all stretched out in the two ends of inner cylinder, the two ends of described inner cylinder are provided with screw thread, described upper cover plate and lower cover twist the two ends in inner cylinder respectively, described upper cover plate is also tightened together with the top of overcoat by securing member, and described lower cover is also tightened together with the bottom of overcoat by securing member.
Described upper cover plate and lower cover are plectane, and radius is consistent with the outer radius of overcoat.
The beneficial effect that the utility model reaches: the utility model comprises inner cylinder and overcoat, operationally, produces friction between overcoat and guide pin bushing, when damaged surfaces, only need change overcoat, save and do not waste.
Accompanying drawing explanation
Fig. 1 is the structural representation of the first embodiment.
Fig. 2 is the structural representation of the second embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, a kind of novel guide pillar, comprises inner cylinder 1 and overcoat 2, inner cylinder 1 is cylinder, the outer wall of inner cylinder 1 is evenly provided with some grooves, and bottom portion of groove is provided with spring 5, and spring 5 one end is outwardly provided with multidiameter 6, the little axle 7 of multidiameter 6 outwardly, the center of overcoat 2 is provided with centre bore, and overcoat 2 is hollow circular cylinder, and centre bore mates with inner cylinder 1, inner cylinder 1 can embed in centre bore, the inwall of centre bore is provided with the shrinkage pool that axle 7 little of multidiameter 6 mates.
In order to ensure operationally, fastening between inner cylinder 1 and overcoat 2, above-mentioned novel guide pillar also comprises upper cover plate 3 and lower cover 4, and upper cover plate 3 and lower cover 4 are plectane, and radius is consistent with the outer radius of overcoat 2.Upper cover plate 3 and lower cover 4 have two kinds of structures, respectively as illustrated in fig. 1 and 2.
The first is that the center of upper cover plate 3 and lower cover 4 does not have screw, be suitable for the situation consistent with the length of inner cylinder 1 and overcoat 2, when inner cylinder 1 embeds the centre bore of overcoat 2, upper cover plate 3 and lower cover 4 lay respectively at two ends, and by securing member, the top of upper cover plate 3, inner cylinder 1 and the top of overcoat 2 are tightened together, by securing member, the bottom of lower cover 4, inner cylinder 1 and the bottom of overcoat 2 are tightened together.
The second is that the center of upper cover plate 3 and lower cover 4 is provided with screw, the length being applicable to inner cylinder 1 is greater than the length of overcoat 2, when inner cylinder 1 embeds the centre bore of overcoat 2, centre bore is all stretched out in the two ends of inner cylinder 1, the two ends of inner cylinder 1 are provided with screw thread, upper cover plate 3 and lower cover 4 twist the two ends in inner cylinder 1 respectively, and upper cover plate 3 is also tightened together by the top of securing member with overcoat 2, and lower cover 4 is also tightened together by the bottom of securing member with overcoat 2.
Above-mentioned novel guide pillar, operationally, produces between overcoat 2 and guide pin bushing and rubs, and when damaged surfaces, only need change overcoat 2, save and do not waste.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
