Abstract
The invention belongs to the field of mechanical structures, and relates to a three-jaw-chuck type mechanical joint rapid assembling structure. The three-jaw-chuck type mechanical joint rapid assembling structure comprises clamping blocks, a guide groove, a screw, a rotation nut and an ejection rod. According to the three-jaw-chuck type mechanical joint rapid assembling structure, a lead screw and nut motion manner is adopted, only the rotation nut needs to be rotated, the ejection rod can eject out the three clamping blocks at the same time under the effect of driving force, and therefore the installation efficiency is greatly improved; and in addition, the central degree of the three-jaw-chuck type mechanical joint rapid assembling structure is high, and the phenomenon of one-side false contact during double-side stressing is avoided. The rotation nut is coated with a high-strength thread-locking agent, and therefore looseness of joints during long-time work is avoided.
Description
The invention belongs to mechanical structure field, relate to a kind of scroll chuck formula mechanical joint quick fixation structure.
Background technology:
Along with the development in epoch, the continuous progress of mechanical automation integral level, in actual production, people are more and more urgent for the raising of efficiency of assembling, Time is money, and high efficiency drives high production capacity, and high production capacity promotes high yield.Using screw fastening or pin tightening of rivet the installation of mechanical joint the most on the market more.
Analyze the above-mentioned prior art mentioned and have the following disadvantages (1), i.e. the technical problem to be solved:
(1) using the mechanical joint of screw fastening in order to ensure fastening strength, at least two screws of symmetrical use, some larger-size structures even need circle distribution one to enclose screw, and efficiency of assembling is extremely low；
(2) structure using pin tightening of rivet also has the most easily detachable shortcoming in addition to efficiency of assembling is low.
Summary of the invention
It is an object of the invention to overcome defect present in existing structure, a kind of scroll chuck formula machinery quick fixation structure of design.This structure is mainly used in mechanical structure field.Solve existing structure efficiency of assembling efficiently low, the shortcoming of fastening strength difference.
To achieve these goals, the technical scheme is that a kind of scroll chuck formula mechanical joint quick fixation structure of design, including fixture block (101), guide groove (102), screw (103), rotate nut (104), push rod (105).
Wherein, described fixture block (101) has guiding, spacing and lozenges, totally 3；Described guide groove (102) has gathering sill at 3, is uniformly distributed, and corresponding positions is equipped with three screwed holes, totally 1；Described screw (103) has 3；Described rotation nut (104) outside is with cross knurled, and inwall has screw thread, totally 1；Described push rod (105) outside is threaded, and there is lozenges at three front end, is uniformly distributed, and forward position, middle part has notch at three, is circumferentially uniformly distributed, has 1.
Its annexation is: smooth in guide groove (102) gathering sill along guiding by described fixture block (101), push rod (105) is axially inserted into, withstand fixture block (101), centering position, limit the rotation on push rod (105) circumferencial direction with screw, rotate nut and screwed with push rod (105) by screw thread.
Advantages of the present invention and having the beneficial effects that: the present invention uses the motion mode of feed screw nut, only need to rotation nut, three fixture blocks can be ejected under the effect of driving force by push rod simultaneously, the installation effectiveness being greatly improved, and scroll chuck formula structure central degree is high, avoiding bilateral stress, the phenomenon that side virtual connection is touched occurs.Rotate nut and be coated with high intensity thread locking agent, it is to avoid joint mobilization in work for a long time.
