Description
Technical field
The utility model relates to a kind of screw rod fixture, is applied to screw rod attachment means process.
Background technology
Fastening parts of automobiles automatic setup system is mainly the core that is assembled into fastening parts of automobiles.In automobile industry, securing member connects is used widely, and therefore securing member has extremely important status in automobile industry.
In the production of reality, the manufacturer of securing member often needs first, by securing member assembled in advance, to prevent damaged screw in transportation., there is larger vacancy in assembled in advance this part how.At present, the solution of domestic employing is more to adopt manually first nut to be locked in advance, then assembles the mode of locking with machinery.Profit assembly method in this way not only will consume a large amount of manpower and materials, and its efficiency of assembling is not high, and labour intensity is large.Along with the raising of quality of life, people more and more pursue high efficiency, large for labour intensity, longevity of service, the work that emolument is low is more and more conflicted, therefore more and more higher for the requirement of automation equipment, the fatal defect of traditional mode of production mode, is more and more not suitable with the theme in epoch.
Utility model content
In view of the deficiencies in the prior art, the purpose of this utility model is to provide a kind of screw rod fixture, contributes to realize fixing for screw rod securing member, is convenient to follow-up assembling.
The technical solution of the utility model is:
A kind of screw rod fixture, comprise installing the base of screw rod and being articulated with the upper cover that on base, screw rod is waled in realization, it is characterized in that: described base upper surface camber groove structure, and on the inwall of arc groove, be provided with lower locating dowel, on described base by the lower locating dowel lower semi-circular cover piece that has been located by connecting, described lower semi-circular cover piece inwall is provided with the screw thread matching with screw flight, the inwall of described upper cover is provided with locating dowel, the described upper locating dowel upper semi-circular cover piece that has been located by connecting, on described upper semi-circular cover piece inwall, be also provided with the screw thread matching with screw flight, and be also provided with in order to be locked the bolt hole in upper cover on the end face of described upper semi-circular cover piece.
Wherein, the end face of described base and upper cover is provided with one semi-circular is overlapped to the baffle plate of piece axial limiting.
Described base upper surface and horizontal direction are 15 ° and tilt to lay.
The utility model has the advantage of: the utility model simple structure, it is convenient to realize, and can carry out accommodation, wide application according to the screw rod of different model.
Brief description of the drawings
The structure cross-sectional schematic of Fig. 1 the utility model embodiment.
Detailed description of the invention
For above-mentioned feature and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below.
With reference to figure 1, the utility model relates to a kind of screw rod fixture, comprise installing the base 1 of screw rod and being articulated with the upper cover 2 that on base, screw rod 9 is waled in realization, described base upper surface camber groove structure, and on the inwall of arc groove, be provided with lower locating dowel 3, on described base by the lower locating dowel lower semi-circular cover piece 4 that has been located by connecting, described lower semi-circular cover piece inwall is provided with the screw thread matching with screw flight, the inwall of described upper cover is provided with locating dowel 5, the described upper locating dowel upper semi-circular cover piece 6 that has been located by connecting, on described upper semi-circular cover piece inwall, be also provided with the screw thread matching with screw flight, and be also provided with in order to be locked the bolt hole 7 in upper cover on the end face of described upper semi-circular cover piece.
The end face of above-mentioned base and upper cover is provided with one semi-circular is overlapped to the baffle plate 8 of piece axial limiting.
Above-mentioned base upper surface and horizontal direction are 15 ° and tilt to lay, so that screw thread following process process is implemented smoothly.
In implementation process, screw rod is installed in the lower semi-circular cover piece of this device, because cover piece inwall is provided with screw flight to the helicitic texture mating, therefore, after bolt is installed into, can effectively stablize firmly screw rod, then upper cover be covered, in the time that upper cover covers, upper semi-circular cover piece in upper cover also stabilizes the first half of screw rod by the helicitic texture of gas inwall, thereby completes clamping action, is convenient to subsequent job.In order to adapt to not threaded needs, cover piece can be changed according to the screw thread of its inwall.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
