The utility model is achieved by the following technical programs:
A damper disassembling fixture for crankshaft of diesel engine, comprises damper supporting seat and L shaped support bar, and described damper supporting seat comprises V-arrangement bracket and lower, and V-arrangement bracket downside is fixedly connected with a lower upper end; V-arrangement bracket comprises two upper plates, the several piece V shaped slab be arrangeding in parallel, two blocks of side plates and lower plate, and two upper plates are fixed on the V-shaped groove mouth of several piece V shaped slab, and several piece V shaped slab downside is fixedly connected with lower plate respectively, and two blocks of side plates are separately fixed at V-arrangement bracket both sides; Described lower comprises several symmetrically arranged support bars and muscle bar and base plate, and several support bars two ends are vertical V-arrangement bracket and the lower plate of connecting respectively, and muscle bar is arranged in a crossed manner in several symmetrically arranged support bars inner side; Described L shaped support bar comprises cross tube, connects piece, vertical rod and vertical rod base plate, cross tube inner end and vertical rod upper end connect that piece is vertical to be fixedly connected with, vertical rod lower end is fixedly connected with vertical rod base plate is vertical.
The purpose of this utility model can also further realize by following technical measures.
The damper disassembling fixture of aforesaid crankshaft of diesel engine, wherein said support bar adopts square steel to make, and described muscle bar and vertical rod all adopt shaped steel to make.
The damper disassembling fixture of aforesaid crankshaft of diesel engine, wherein said cross tube diameter is less than damper supporting seat fixing hole diameter.
The damper disassembling fixture of the utility model crankshaft of diesel engine is simple in structure, easy to use, method for dismounting is quick, safety, with damper supporting seat, hold damper, and with L shaped support bar, moving axially of damper led, can from crankshaft of diesel engine termination, pull down easily damper intactly, reduce maintenance cost, improved the removal efficiency of damper.
Accompanying drawing explanation
Fig. 1 is the front view of the utility model damper supporting seat;
Fig. 2 is the front view of L shaped support bar;
Fig. 3 is the sketch that uses the utility model dismounting damper.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As depicted in figs. 1 and 2, the damper disassembling fixture of crankshaft of diesel engine of the present utility model comprises damper supporting seat 1 and L shaped support bar 2, damper supporting seat 1 and the L shaped support bar 2 of the present embodiment are welding structural element, damper supporting seat 1 comprises V-arrangement bracket 11 and lower 12, and V-arrangement bracket 11 downsides and lower 12 upper ends are soldered.3 V shaped slabs that V-arrangement bracket 11 comprises two upper plates 111, be arranged in parallel 112, two side plates 113 and lower plates 114, two upper plates 111 are combined on the V-shaped groove mouth 115 that V-arrangement is welded in 3 V shaped slabs 112,3 V shaped slab 112 downsides are soldered with lower plate 114 respectively, two blocks of side plates 113 are welded in respectively V-arrangement bracket 11 both sides, and side plate 113 upsides and side plate 116 are soldered.
Lower seat 12 comprises 4 symmetrically arranged support bars 121 and muscle bar 122 and base plate 123, and the support bar 121 of the present embodiment adopts square steel to make.Vertical soldered V-arrangement bracket 11 and lower plate 114 are distinguished in 4 support bar two ends, and the muscle bar 122 that channel-section steel is made is arranged in a crossed manner 4 symmetrically arranged support bar 121 inner sides.
L shaped support bar 2 comprises cross tube 21, connects piece 22, vertical rod 23 and vertical rod base plate 24, and cross tube 21 left ends insert connecing in piece 22 of vertical rod 23 upper ends, by holding screw 25, are fixedly connected with vertical rod 23.Vertical rod 23 lower ends are vertical soldered with vertical rod base plate 24.In order to improve the rigidity of L shaped support bar 2, between cross tube 21 and vertical rod 23, also weld a hound 26.For the ease of in unloading process, moving axially of damper 3 being led, cross tube 21 diameters are less than the diameter of damper supporting seat fixing hole.
As shown in Figure 3, use the process of the utility model dismounting crankshaft of diesel engine damper as follows:
1) damper supporting seat 1 is placed on the lifting fork plate 4 of hand operated transport front portion, adjusts hand operated transport position, make damper supporting seat 1 aim at damper 3 downsides; Then lifting lifting fork plate 3, damper supporting seat 1 rises thereupon, until V-shaped groove mouth 115 is held damper 3.
2) unload one by one the attachment screw that damper 3 is connected with crankshaft of diesel engine 5 terminations, the vertical rod base plate 24 of L shaped support bar 2 is placed on diesel engine assembling base 6, and cross tube 21 is pointed to damper 3.Rotating oscillation damping device 3, makes an one screw hole aim at cross tube 21.
3) L shaped support bar 2 moves towards damper 3 directions, and cross tube 21 inserts in a screw hole of damper 3.
4) the micro-lifting of lifting fork plate 4, makes cross tube 21 circumferentially and screw hole disengages completely, and hand steered damper 3 avoids it to rock; Then promoting hand operated transport moves towards leaving crankshaft of diesel engine termination direction; Damper 3 is lower outside the moving of guiding of cross tube 21, and after damper 3 end faces and crankshaft of diesel engine termination 51 are disengaged completely, hand operated transport stops mobile.
5) move L shaped support bar 2, make cross tube 21 depart from a screw hole of damper 3 completely.Lifting fork plate 4 declines and puts in place, and promotion hand operated transport carries damper 3 and leaves the diesel engine of pulling down damper 3.
In addition to the implementation, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
