Utility model content

For solving above-mentioned technical problem, the purpose of this utility model is to propose a kind of diesel engine piston connecting rod extractor work Dress.

This utility model is to complete above-mentioned purpose to adopt the following technical scheme that：

A kind of diesel engine piston connecting rod extractor frock, described frock has the tensioner being placed in piston upper recess Fastened by O-ring between disk, and tensioner disk and piston；Described tensioner disk is two halves formula structure, and described tensioner disk center has The through hole passing through in order to T-bar；Described T-bar is made up of with the montant being connected to cross bar bottom cross bar；Montant described in T-bar Bottom there is the frustum in flaring footpath from top to bottom, and described frustum is so that tensioner disk is expanded when with described tensioner disk cooperation The structure opened；Described tensioner disk is nested with the montant described in T-bar；The middle part of montant described in T-bar has to install leads External screw thread to compressor arm；Described guiding compressor arm is nested with the middle part of montant described in T-bar；Described guiding compressor arm tool There is the sleeve that internal face is female thread, the bottom of described sleeve is connected with pressure strip, and described pressure strip is located at described tensioner The top of disk, and contact with described tensioner disk, the sleeve constituting described in guiding compressor arm can be along T-bar in the presence of external force Described montant moves up and down, and promotes the structure that described pressure strip moves down, and constitutes described tensioner disk and transport downward In dynamic process, in the presence of the frustum described in T-bar, tensioner, in described piston, is fastened as one with described piston The structure of body.

The utility model proposes a kind of diesel engine piston connecting rod extractor frock, using technique scheme, not only tie Structure is simple, with low cost, can also avoid lifting by crane machine, reduce labor intensity and maintenance cost, shorten maintenance time, carry The high rapid rush-repair ability to diesel engine.

Brief description

Fig. 1 is structural representation of the present utility model.

In figure：1st, T-bar；2nd, guide compressor arm；3rd, tensioner disk；4th, O-ring, 5, frustum, 6, pressure strip, 7, sleeve, 8, Piston.

Specific embodiment

In conjunction with the drawings and specific embodiments, this utility model is illustrated：

As shown in figure 1, a kind of diesel engine piston connecting rod extractor frock, described frock has that to be placed on piston upper end recessed Tensioner disk 3 in groove, and fastened by O-ring 4 between tensioner disk 3 and piston 8；Described tensioner disk 3 is two halves formula structure, and described Tensioner disk 3 center has the through hole passing through in order to T-bar 1；Described T-bar 1 is by cross bar and the montant being connected to cross bar bottom Constitute；The bottom of montant described in T-bar has the frustum 5 in flaring footpath from top to bottom, and described frustum 5 is to rise with described The structure that tensioner disk is expanded is made during tight disk cooperation；Described tensioner disk 3 is nested with the montant described in T-bar；Perpendicular described in T-bar The middle part of bar has the external screw thread installing guiding compressor arm 2；Described guiding compressor arm 2 is nested with montant described in T-bar Middle part；Described guiding compressor arm 2 has the sleeve 7 that internal face is female thread, and the bottom of described sleeve is connected with pressure strip 6, and described pressure strip 6 is located at the top of described tensioner disk 3, and contact with described tensioner disk 3, constitute guiding compressor arm institute The sleeve 7 stated can move up and down along montant described in T-bar in the presence of external force, and promotes described pressure strip 9 to move down Structure, and constitute described tensioner disk 3 during moving downward, in the presence of the frustum 5 described in T-bar, tensioner In described piston 8, it is fastened as a whole with described piston 8.

In the groove that frock first puts tension disk 3 into piston when using；When this utility model uses, guide spiro rod 2 leads to Cross rotation to move up and down on threaded rod, guide spiro rod 2 is rotated down makes tensioner disk move down, when tensioner disk 3 and spiral shell During the taper-face contact of rasp bar 1 lower end, tensioner disk 3 can open, and its external diameter increases, when in the external diameter and pistion recess of tension disk 3 When footpath fits tightly, piston connecting rod unit easily can be extracted by pulling up the handle of threaded rod 1.Note：This frock is when using First tensioner disk 3 is put in the groove of piston.
