Abstract
The utility model provides a fastening bolt which belongs to the technical field of mechanical parts and solves the problems that the existing bolt can not be positioned and can make idle rotation during mounting. The fastening bolt comprises a cylindrical threaded column and a lock cap fixedly connected to the end part of the threaded column; and the lock cap is provided with an extension part which is fixedly connected with a positioning part that is at the same side as the threaded column. The fastening bolt has simple structure, is convenient in positioning, and can prevent the idle rotation of the threaded column.
Description
Technical field
The utility model belongs to the mechanical part technical field, relates to a kind of connected element that assembles usefulness, particularly a kind of clamping bolt with location and anti-lost motion functionality.
Background technique
Bolt is the fastening piece of using always, is widely used in various machinery.During use, bolt is passed the part which floor need link together, the head of bolt is clamped in part surface, the other end nut check of bolt, but bolt is when urgent or loading torque, need prevent the bolt rotation and realize the urgent of bolt with the head or the specialized designs limit structure of professional tool clamping bolt, yet for the place that can't put in professional tool or layout position-limit mechanism because of arrangement space is too little, just there is the problem that can't tighten because of self idle running in bolt.
In use just there is another problem in bolt: when component because the restriction of arrangement space or mounting point, in the time of can't realizing locating with porous installation and self structure, because bolt has only a locating point, can not determine a plane of orientation, so just can't realize the location between the part, can cause the crooked phenomenon consistent of part assembling with the department of assembly.
Summary of the invention
The purpose of this utility model is at the above-mentioned problems in the prior art, and a kind of clamping bolt with locating function is provided.
The purpose of this utility model can realize by following technical proposal: a kind of clamping bolt, the screw column and the lock nut that is connected in the screw column end that comprise column, it is characterized in that described lock nut has extension part, be fixed with locating piece on the described extension part with the screw column homonymy.
Two locating points of screw column in this clamping bolt and locating piece have been determined plane of orientation, when screw column and locating piece pass the mounting hole of connected piece correspondence together, connected piece can be realized the location, and connected piece can not assemble crooked and the inconsistent problem of assembling.
Simultaneously, there is spacing between screw column and the locating piece, when screw column and locating piece pass the mounting hole of connected piece correspondence together, nut is installed on screw column, screw column is when being subjected to running torque, locating piece provides an opposing torque, and effective like this idle running that prevents screw column can solve because the restriction of arrangement space or mounting point can't be installed or self structure realizes the problem of locating with porous.
In above-mentioned a kind of clamping bolt, described locating piece is a locating stud, and the parallel axes of described locating stud is in the axis of screw column.On extension part, offer hole slot, during assembling locating stud passed the hole slot on the extension part, locating stud and hole slot interference fit, easy to process, and locating stud is locating element commonly used, make the low cost of manufacture of clamping bolt like this.
As another kind of situation, in above-mentioned a kind of clamping bolt, described locating piece is a locating bump, and described locating bump vertically is fixed on extension part.The volume of locating bump has guaranteed the area of contact of locating between itself and the connected piece, and locating effect is better.
In above-mentioned a kind of clamping bolt, described extension part is tabular.
Compared with prior art, this clamping bolt adopts the design of screw column and locating piece, and is simple in structure, and the location is convenient, makes the assembling high conformity of connected piece; And have spacing between screw column and the locating piece, when screw column when being subjected to running torque, locating piece provides an opposing torque, can effectively prevent the idle running of screw column.

Fig. 3 is the schematic perspective view of the another kind of structure of this clamping bolt.
Among the figure, 1, screw column; 2, lock nut; 3, extension part; 4, locating stud; 5, locating bump; 6, connected piece; 7, nut.
Embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, this clamping bolt comprises the screw column 1 and the lock nut 2 that is connected in screw column 1 end of column, and lock nut 2 has tabular extension part 3, and lock nut 2 and extension part 3 integral body are cam-like, certainly can also be tabular or discoideus for the side.
Be fixed with locating piece on the extension part 3 with screw column 1 homonymy.Locating piece is a locating stud 4 in the present embodiment, and the parallel axes of locating stud 4 is in the axis of screw column 1.Add man-hour, earlier on extension part 3, offer hole slot, during assembling locating stud 4 passed the hole slot on the extension part 3, locating stud 4 and hole slot interference fit, easy to process like this, and locating stud 4 is locating element commonly used, make this clamping bolt low cost of manufacture.
As shown in Figure 2, when this clamping bolt uses, when screw column 1 and locating piece pass the mounting hole of connected piece 6 correspondences together, because two locating points of screw column 1 and locating piece have been determined plane of orientation, so realized the location between the connected piece 6, connected piece 6 can not assemble crooked and the inconsistent problem of assembling.Simultaneously, there is spacing between screw column 1 and the locating piece, nut 7 is installed on screw column 1, screw column 1 is when being subjected to running torque, locating piece provides an opposing torque, effective like this idle running that prevents screw column 1 can solve because the restriction of arrangement space or mounting point can't be installed or self structure realizes the problem of locating with porous.
As shown in Figure 3, present embodiment is basic identical with embodiment 1 structure and principle, and different place is that the locating piece in the present embodiment is a locating bump 5, and locating bump 5 vertically is fixed on extension part 3.Locating bump 5 is connected with extension part 3 welding, the volume of locating bump 5 guaranteed its with connected piece 6 between the area of contact of locating, locating effect is better
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used terms such as screw column 1, lock nut 2, extension part 3, locating stud 4, locating bump 5, connected piece 6, nut 7 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
