The bucket rod sleeve pressing machine is simple in structure, is convenient to operate and is low in use cost, and once stretching of the piston rod of the sleeve pressing oil cylinder can be used for pressing the two shaft sleeves into the two sides of the bucket rod, so that the working efficiency and the assembling precision are improved.
Description
Technical field
The present invention relates to a kind of excavator bucket rod sleeve press fitting device, especially a kind of hydraulic power of utilizing is pressed into sleeve pressing machine in the excavator boom axis hole with axle sleeve, belongs to engineering machinery erection unit technical field.
Background technology
Dipper is the vitals of digger operating device, and the dipper front-end and back-end are respectively equipped with the axis hole hinged with power shovel, swing arm, also are provided with rocking bar, oil cylinder connecting shaft hole on it, are equipped with axle sleeve in each axis hole, to avoid the wearing and tearing of each axis hole of dipper and bearing pin.Axle sleeve is generally by the assembling of liquid nitrogen cold-shrinkage method at present, axle sleeve is placed on a period of time shrinkage distortion in subzero tens liquid nitrogen containers of spending, the axle sleeve after the shrinkage distortion is directly thrown in the dipper axis hole, at normal temperatures, axle sleeve expands rear and dipper axis hole interference fit links into an integrated entity again.This assembly method labour intensity is large, and efficiency of assembling is low, precision is low, causes easily the crooked even damage of axle sleeve in the assembling process, and liquid nitrogen is volatile simultaneously, and annual the needs consumes a large amount of liquid nitrogen, and use cost is higher.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, easy to operate, use cost is low, assembly precision is high bucket arm pressing sleeve machine.
The present invention is achieved by the following technical programs:
A kind of bucket arm pressing sleeve machine, comprise derricking gear, hydraulic power unit, level is lifted on the gland oil cylinder on the derricking gear, block, two axle sleeves and two glands, described gland oil cylinder is connected with hydraulic power unit by hydraulic tube, pass the dipper both sides after gland cylinder piston rod one end stretches out and treat last item cover axis hole, two glands and two axle sleeves are enclosed within respectively on the gland cylinder piston rod, two axle sleeves are symmetricly set on the dipper both sides, and the axis hole position for the treatment of the last item cover with the dipper both sides is corresponding, two glands are symmetricly set on the axle sleeve outside, and described block is fixed on the gland cylinder piston rod one end termination.
Purpose of the present invention can also further realize by following technical measures.
Aforesaid bucket arm pressing sleeve machine, wherein said derricking gear comprises traveling cradle and loop wheel machine, described traveling cradle comprises the crossbeam that vertical rod that mobile chassis, lower end be fixedly connected with mobile chassis and an end are fixedly connected with the vertical rod upper end, and described gland oil cylinder horizontally suspends on crossbeam by loop wheel machine.Wherein said gland is the staged gland.
The present invention is simple in structure, and is easy to operate, and use cost is low, and the once flexible of gland cylinder piston rod just can all be pressed into two axle sleeves in the dipper both sides, improved operating efficiency and assembly precision.
Advantage and disadvantage of the present invention will be for illustration and explanation by the non-limitative illustration of following preferred embodiment, and these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the I section enlarged drawing of Fig. 1.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
As depicted in figs. 1 and 2, the present invention includes derricking gear 1, hydraulic power unit 2, level and be lifted on gland oil cylinder 3 on the derricking gear 1, block 4, two axle sleeves 5 and gland 6, gland oil cylinder 3 is connected with hydraulic power unit 2 by hydraulic hose 7, pass dipper 8 both sides after gland cylinder piston rod 31 1 ends stretch out and treat last item cover axis hole 81, two glands 6 and two axle sleeves 5 are enclosed within respectively on the gland cylinder piston rod 31, two axle sleeves 5 are symmetricly set on dipper 8 both sides, and treat that with dipper 8 both sides axis hole 81 positions of last item cover are corresponding.Gland 6 is the staged gland, and its small end puts in the axis hole 81, large end play to axle sleeve 5 be pressed into axis hole 81 time positioning action, guarantee that gland 6 is pressed in the axis hole 81 fully, so that gland 6 axis holes 81 interference fit are fixedly connected with dipper 8.Block 4 is fixed on the gland cylinder piston rod 31 1 end terminations, plays the effect by gland 6 push collar 5.
Derricking gear 1 comprises traveling cradle 11 and loop wheel machine 12, traveling cradle 11 comprises that mobile chassis 111, an end are welded in vertical rod 112 on the mobile chassis 111 and an end and are welded in crossbeam 113 in the vertical rod 112, loop wheel machine 12 is the balanced type loop wheel machine, loop wheel machine 12 is suspended on the crossbeam 113, can vertically move along crossbeam 113, gland oil cylinder 3 horizontally suspends on the suspension hook of loop wheel machine 12.
The course of work of the present invention is as follows:
First dipper 8 is placed on the underframe 9, by the sling height of adjusting loop wheel machine 12 and loop wheel machine 12 is adjusted gland oil cylinder 3 in the lateral attitude of crossbeam 113 hanging position, treats last item cover axis hole 81 so that gland cylinder piston rod 31 is aimed at dipper 8 both sides.Start hydraulic power unit 2, after gland cylinder piston rod 31 is overhanging, put in turn first 1 gland 6 and 1 axle sleeve 5, again gland cylinder piston rod 31 is passed dipper 8 both sides and treat last item cover axis hole 81, then put in turn 1 axle sleeve 5 and 1 gland 6, and block 4 is fixed on gland cylinder piston rod 31 terminations, then gland cylinder piston rod 31 is retracted, and by the gland 6 that block 4 promotes dippers 8 one sides axle sleeve 5 is compressed into dipper 8 outsides; Gland cylinder piston rod 31 continues to retract, and it is traversing to promote dipper 8, and dipper 8 opposite side axle sleeves 5 are compressed into dipper 8 inboards by gland 6, until that dipper 8 stops is traversing, finishes being press-fitted of axle sleeve 5 of dipper both sides.
In addition to the implementation, the present invention 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 requirement of the present invention.
