Abstract
The utility model discloses a novel earthmover half shaft press-mounting device which comprises a hydraulic control box, an oil pipe, a platform, an oil tank support, an oil tank, a press bush, a positioning guide bush, a support, a tapered wedge, a half shaft, a rear axle and bolts. The novel earthmover half shaft press-mounting device has the advantages that the hydraulic control box is used for controlling the forward and backward of the oil tank, the maximum press-in force is up to 20MPa, the running speed of a pressure head is 6-8mm/s, thereby a half shaft with bigger interference can be pressed in and center positioning is better. Further because of the addition of the support, the press mounting process is faster and more accurate, and the press mounting of the bilateral half shaft can be completed with one clamping.
Description
Technical field
The utility model relates to the bull-dozer equipment technical field, is specially a kind of earth mover semiaxis press-loading apparatus.
Background technology
The existing device that semiaxis is installed comprises screw rod, platen and hydraulic jack, at first semiaxis is knocked in half axis hole during installation, then four screw rods is passed platen, is fixed in the screwed hole of four M27 of rear axle shaft hole near; Hydraulic jack is put between platen and the semiaxis, slowly semiaxis is pressed into, inadequate such as the hydraulic jack stroke, can between jack and platen, increase cushion block.
Semiaxis is that level is contained on the back axle, it is the interference fit of the large magnitude of interference with cooperating of back axle axis hole, and its setting pressure is 15-54T, and existing semiaxis press-loading apparatus easily draws near four silk holes half axis hole bad, and twice clamping of needs just can be pressed into the semiaxis of both sides, and operation is wasted time and energy.
Existing half shaft mounting device pressing-in force is less, to the having relatively high expectations of the semiaxis magnitude of interference, can only match semiaxis and install during assembling; And when installing, the both sides semiaxis need distinguish clamping.
The utility model content
For above-mentioned technical problem, the utility model provides a kind of earth mover semiaxis press-loading apparatus, adopts the HYDRAULIC CONTROL SYSTEM oil cylinder to advance, thereby can semiaxis be pressed in half axis hole of back axle fast and accurately.
The technical scheme that its technical problem that solves the utility model adopts is, this earth mover semiaxis press-loading apparatus, structure mainly comprise hydraulic control box, oil pipe, platform, cylinder bracket, oil cylinder, gland, centering guide pin bushing, bearing, wedge, semiaxis, back axle and bolt; Described cylinder bracket is two, is installed on the platform two ends with the bolt symmetry, and described oil cylinder is installed in the cylinder bracket, and described bearing is installed in the platform middle part by bolt, and described back axle is installed on bearing top; Two semiaxis are installed on the bearing two ends by the bolt symmetry, and described semiaxis is equipped with the centering guide pin bushing towards bearing one end, and the other end is equipped with gland; On the platform of bearing both sides wedge is installed; Described cylinder bracket is connected with hydraulic control box by oil pipe.
The beneficial effect that the utility model produces is, the utility model adopts moving forward and backward of hydraulic control box control oil cylinder, maximum pressing-in force can reach 20MPa, the pressure head speed of service is 6-8mm/s, therefore can be pressed into rapidly the larger semiaxis of the magnitude of interference, and centering is good, simultaneously, owing to having increased bearing, make to press-fit process more fast, accurately, only need clamping once can finish press-fiting of both sides semiaxis.
Description of drawings
Be elaborated below in conjunction with the drawings and specific embodiments:
Fig. 1 is the utility model structural representation
Fig. 2, Fig. 3 are the utility model centering guide sleeve structure schematic diagram
Fig. 4, Fig. 5, Fig. 6 are the utility model seat structure schematic diagram
Among the figure, 1, hydraulic control box 2, cylinder bracket 3, oil cylinder 4, gland 5, bolt 6, centering guide pin bushing 7, bearing 8, oil pipe 9, platform 10, wedge 11, semiaxis 12, back axle
The specific embodiment
As shown in the figure, the utility model is a kind of earth mover semiaxis press-loading apparatus, and structure mainly comprises hydraulic control box 1, oil pipe 8, platform 9, cylinder bracket 2, oil cylinder 3, gland 4, centering guide pin bushing 6, bearing 7, wedge 10, semiaxis 11, back axle 12 and bolt 5; Described cylinder bracket 2 is two, is installed on platform 9 two ends with bolt 5 symmetries, and described oil cylinder 3 is installed in the cylinder bracket 2, and described bearing 7 is installed in platform 9 middle parts by bolt 5, and described back axle 12 is installed on bearing 7 tops; Two semiaxis 11 are installed on bearing 7 two ends by bolt 5 symmetries, and described semiaxis 11 is equipped with centering guide pin bushing 6 towards bearing 7 one ends, and the other end is equipped with gland 4; On the platform 9 of bearing 7 both sides wedge 10 is installed; Described cylinder bracket 2 is connected with hydraulic control box 1 by oil pipe 8.
Specifically press-fit process as follows:
Smear the molybdenum bisuphide of lubricate in semiaxis 11 holes of back axle 12, in special hanger lifting semiaxis 11 to half axis holes, centering guide pin bushing 6 is installed, prevent from press-fiting semiaxis off-axis in the process.
Lifting back axle 12 is to bearing 7, tight a bolt 5, back axle 12 is fixed on the bearing 7, bearing 7 is fixed on the platform 9 with bolt 5, because the size of the back axle 12 of different model bull-dozer is different, therefore every kind of bull-dozer has special carrier, only need turn on bolt 5 when needing to change, and changes other bearing and gets final product.
Gland 4 is installed, is prevented from press-fiting damage semiaxis 11 in the process.
By moving forward and backward of hydraulic control box 1 control oil cylinder 3, thereby semiaxis 11 is pressed in the back axle 12.When press-fiting, both sides semiaxis 11 should press-fit respectively, and opposite side oil cylinder 3 pressure heads should be in the state of returning when namely press-fiting a side semiaxis, must not contact with semiaxis.
Finish and to turn on bolt 5 after press-fiting.
The utility model is not limited to above-mentioned embodiment, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the present utility model.
The technology that the utility model is not described in detail, shape, structure partly are known technology.
