Abstract
The utility model discloses a mounting structure of a locating pin of a cavity of a filter, which comprises the cavity of the filter and the locating pin, wherein the cavity of the filter is provided with a screw hole provided with internal thread, and a locating taper hole; the end part of the locating pin is sequentially provided with a stud and a taper surface part; the stud of the locating pin is connected with the screw hole of the cavity of the filter by screw thread; and the taper surface part of the locating pin is matched with the locating taper hole of the cavity of the filter for locating. The mounting structure effectively solves the problems that the size of the compression joint locating pin is difficult to control, the compression joint locating pin is difficult to assemble, and the pure thread locating pin is low in locating accuracy, and has the advantages of being simple in structure, high in locating accuracy and high in mounting accuracy.
Description
Technical field
The utility model relates to a kind of communications parts, particularly a kind of filter cavity alignment pin mounting structure.
Background technology
At present; The mounting means of used alignment pin generally adopts the mode of crimping or the mode that is threaded in the filter industry; The mode of crimping is that alignment pin is clamp-oned in the chamber hole through anchor clamps; All than higher, the requirement of strength of corresponding alignment pin is also higher to the required precision in the hole on alignment pin pressing part and the cavity, thereby causes difficulty of processing.And the mode that is threaded is because the characteristics of threaded engagement cause can existing between alignment pin and the screw certain clearance, and its quality of fit is too low, can't satisfy the installation accuracy of filter and its equipment.
Summary of the invention
The purpose of the utility model is in order to overcome the above-mentioned background technology to the filter installation influence; A kind of conical surface alignment pin group of high precision screw type of attachment is provided, the requirement that simple realization easily of its processing and fabricating and the high accuracy that cost of manufacture is lower, the while can be satisfied alignment pin on the filter product are again installed.
For realizing above-mentioned purpose; The filter cavity alignment pin mounting structure of the utility model design; Comprise filter cavity and alignment pin, filter cavity is provided with tapped screw and location taper hole, and the end of said alignment pin is provided with double-screw bolt and tapering face portion successively; The double-screw bolt of said alignment pin cooperates with the screw of filter cavity, and the tapering face portion of said alignment pin cooperates the location with the location taper hole of filter cavity.。
In technique scheme: the tapering face portion of said alignment pin is connected with concentric column part.
In technique scheme: be provided with a through hole or a circle groove on the said column part.
The utlity model has following beneficial effect: the screw of installing on conical surface alignment pin and the cavity and taper hole handling ease guarantee, the high advantage of assembling back alignment pin positioning accuracy, and the installation accuracy of filter is greatly improved.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structural representation of the utility model embodiment 2;
Among the figure: 1, alignment pin, 1.1, double-screw bolt, 1.2, the tapering face portion, 1.3, column part, 1.4, through hole, 1.5, groove, 2, filter cavity 2.1, screw, 2.2, the location taper hole.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to describe in detail:
The utility model filter cavity alignment pin mounting structure; Comprise filter cavity 2 and alignment pin 1; Filter cavity 2 is provided with tapped screw 2.1 and location taper hole 2.2, and the end of alignment pin 1 is provided with double-screw bolt 1.1 and tapering face portion 1.2 successively, thereby the double-screw bolt 1.1 of alignment pin 1 is fixed alignment pin with the screw 2.1 of filter cavity 2 through being threaded; The tapering face portion 1.2 of alignment pin 1 cooperates the location with the location taper hole 2.2 of filter cavity 2, guarantees the positioning accuracy of alignment pin.The tapering face portion 1.2 of alignment pin 1 is connected with concentric column part 1.3.
Embodiment 1
Except said structure, because the needs that connect are installed, column part 1.3 is provided with through hole 1.4, and is as shown in Figure 1.
Embodiment 2
Except said structure, because the needs that connect are installed, a circle groove 1.5 is consulted shown in Figure 2 on the column part 1.3.
The alignment pin of the utility model is threaded fastening with filter cavity dependence, conical surface alignment pin and cavity rely on the cone match mode effectively to guarantee the high-precision requirement that alignment pin is installed.The utility model has solved the difficult control of crimping alignment pin size, bad assembling, the not enough problem of pure screw thread alignment pin positioning accuracy effectively.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from the spirit and the scope of the utility model.Like this, belong within the scope of the utility model claim and equivalent technologies thereof if these of the utility model are revised with modification, then the utility model also is intended to comprise these changes and modification interior.
The content of not doing in this specification to describe in detail belongs to this area professional and technical personnel's known prior art.
