Description
Technical field
The utility model belongs to the technical field of axle main speed reducer general assembly, and in particular to one kind can ensure without solid
Surely the final drive casing and bushing Bidirectional clamping mounting device of support axle main speed reducer shell bushing press-mounting assembly technical requirement.
Background technology
Extremely important, final drive casing and main reducing gear hub plate are assembled axle assembly in the assembly of final drive casing bushing press-mounting
The assembly of set mainly includes how final drive casing bushing being fitted into final drive casing, the assembly precision of final drive casing bushing
Directly influence axle assembly dimensional chain for assembly.Tradition assembly is assembled using conventional press-fitting tool, by main reducing gear hub plate
It is placed on press and is pressed after set and tooling combination, since tooling does not fix supporting point, final drive casing bushing subtracts with master
Fast device shell stress unbalance loading during press fitting is easy 4 pressure break of final drive casing and final drive casing bushing, while without accurate
The consistency for positioning assembly is bad, can not ensure assembly precision and quality, and then directly affects axle assembly assembly due to unbalance loading
Caused precision and quality.
Invention content
In view of the above technical problems, a kind of final drive casing of the utility model offer and bushing Bidirectional clamping mounting device.
The technical solution adopted in the utility model is：
A kind of final drive casing of the utility model offer and bushing Bidirectional clamping mounting device, for realizing final drive casing
With final drive casing bushing registration, the good assembly of press fitting consistency, including reinforcing screw rod, upper locating piece, lower clamping are realized
Block, reinforcing screw rod pass perpendicularly through the centre bore of locating piece and are linked and packed together with the centre bore of lower gripping block, wherein upper fixed
Position block and lower gripping block are provided with to be needed to assemble the position of parts with the assembly matched locating slot of parts, locating slot limitation positioning
It sets, realization is axially precisely positioned, and upper locating piece lower surface is parallel with the lower upper surface of gripping block, realizes positioned parallel, described
It is a nut to reinforce screw tip, and screw surface is provided with the spiral shell to match with upper locating piece centre bore, lower gripping block centre bore
Line, the centre bore of the upper locating piece are overlapped with the center centerline hole of lower gripping block, at the same with preassembled Central of the parts
The center line in hole overlaps, and screw rod drives upper locating piece and lower gripping block the part being pressed will to be needed to carry out in a manner of Bidirectional clamping
Installation, the utility model are suitable for irregular structure and the installation without fixed supporing shell bushing.
That the utility model has the characteristics that is convenient, efficient, installation dimension is accurate.
Description of the drawings
The assembly structure schematic diagram of 1 the utility model of attached drawing
2 utility model works status architecture schematic diagram of attached drawing
Specific embodiment
In order to make the technical problems, technical solutions and advantages to be solved by the utility model clearer, below in conjunction with attached drawing
And specific embodiment is described in detail.
Embodiment final drive casing provided by the utility model and bushing Bidirectional clamping are pacified in conjunction with attached drawing 1 to Fig. 2 first
Assembling device is introduced.
As shown in Figure 1 to Figure 2, the final drive casing that the utility model embodiment provides is filled with the installation of bushing Bidirectional clamping
It sets, for realizing final drive casing 3 and 4 registration of final drive casing bushing, realizes the good assembly of press fitting consistency, including add
Power screw rod 1, upper locating piece 2, lower gripping block 5, the reinforcing screw rod 1 pass perpendicularly through the centre bore of locating piece 2 and lower clamping
The centre bore of block 5 is linked and packed together, is matched with assembly parts wherein the upper locating piece 2 and lower gripping block 5 is provided with
Locating slot, locating slot limitation need assemble parts position, realize it is axially precisely positioned, under the upper locating piece 2
Surface is parallel with the upper surface of lower gripping block 5, realizes that positioned parallel, the reinforcing screw rod 1 drive upper locating piece 2, lower clamping
Block 5 is installed in a manner of Bidirectional clamping, and the utility model is equally applicable to irregular structure and without fixed supporing shell lining
The installation of set.
Further, 1 top of reinforcing screw rod as shown in Figure 1 is a nut, and screw surface is provided with and upper positioning
The screw thread that 2 centre bore of block, 5 centre bore of lower gripping block match.
Further, the center centerline hole weight of the centre bore and lower gripping block 5 of the upper locating piece 2 as shown in Figure 1
It closes, while being overlapped with the center line in preassembled Central of the parts hole.
The assembly and the course of work of the utility model are as shown in Fig. 2, the upper locating piece 2 and 3 bushing of final drive casing
The upper surface precise positioning of mounting hole, while 4 upper end of final drive casing bushing with centre bore being put into the lining of final drive casing 3
Mounting hole lower surface is covered, 4 lower end of final drive casing bushing with centre bore is put into the locating slot of lower gripping block 5, finally will
Screw rod 1 is reinforced to pass through in upper locating piece 2, the bushing mounting holes of final drive casing 3, final drive casing bushing 4, lower gripping block 5
Heart hole makes the reinforcing that screws up with a wrench, and gripping block 5 is connected through a screw thread the top spiral shell for moving upwards, while reinforcing screw rod 1 at present for this
Upper locating piece 2 and the bushing mounting holes upper surface of final drive casing 3 are closely press fit together by cap, bilateral stress, and master is driven to subtract
Fast device hub plate set 4 enters in the bushing mounting holes of final drive casing 3, completes tooling assembly.
