Abstract
The utility model relates to a special tool for disassembling and assembling an automobile differential assembly. The existing maintenance tool only reaches the action of connecting a chassis. In the utility model, through a screw rod type elevating mechanism which has an arc-shaped machine frame and is arranged on a moving machine frame and an L-shaped movable machine frame which is arranged at one opposite side, a universal joint connecting disk locking mechanism which is arranged in a strip-shaped hole on the L-shaped machine frame is movably connected with the moving machine frame through a screw bolt. The differential assembly falls into the corresponding position between the arc-shaped machine frame and the universal joint connecting disk to prevent the differential assembly from skewing. The utility model is easily operated by a person and ensures that assembly is precise when the assembly is disassembled and assembled.
Description
The utility model relates to a kind of special tool of dismounting automobile differential assembly.
The existing diff that services a car adopts four-bar linkage mostly, flexibly connects with bearing pin articulated manner and carriage, by the lifting of jack, realizes the diff of dismounting automobile.But it can only play the effect that connects dish, and during dismounting, diff easily rolls, thus easy damaged annular soft seal pad or screw flight, thus destroyed the leak tightness of diff, make its easy oil impregnate.
The purpose of this utility model provides and a kind ofly saves time, laborsaving, and can guarantee the special tool of diff dismounting precision.
For achieving the above object, technical solution of the present utility model is as follows:
A kind of instrument of dismounting automobile differential assembly, comprise moving frame 1 and the lifting mechanism that is placed on the moving frame, its special character is: above-mentioned lifting mechanism is the screw type lifting mechanism, and leading screw 4 upper ends are provided with arc frame 7, and locating dowel pin 8 is set on the arc frame 7; A relative side with the screw type lifting mechanism is provided with L type movable machine frame 15 on moving frame, in the bar hole 13 of L type movable machine frame 15 upper ends universal-joint terminal pad lockout mechanism 11,12,14 is set, its lower end is connected with moving frame 1 with bolt 17 by strip hole 16, makes diff 6 fall into corresponding site between arc frame 7 and the universal-joint terminal pad lockout mechanism 11,12,14.
The grow up to be a useful person instrument of assembly of above-mentioned dismounting automobile differential, its special character is: the terminal pad 11 that above-mentioned universal-joint connects the pipe link of lockout mechanism be provided with universal-joint on the corresponding hole of bolt, be provided with fine setting swivel nut 12 between terminal pad 11 and the pipe link, its other end is respectively arranged with sliding wheel 14 in the front, rear, left and right of the bar hole (13) of L type frame.
The instrument of above-mentioned dismounting automobile differential assembly, its special character is: the nut 3 of above-mentioned screw-threaded shaft elevator structure is provided with rotating handles 2, ball 18 between the bottom surface of nut and the moving frame 1, be located at leading screw 4 lower ends of matching with it in the nut and be provided with guide groove 9, the guide bolt 10 in the guide groove 9 is fixed on the moving frame 1.
The instrument of above-mentioned dismounting automobile differential assembly, its special character is: be provided with rotary fine adjustment nut 5 between above-mentioned arc frame 7 and the rotating threaded shaft 4.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the utility model structural representation;
Fig. 2 is the screw-threaded shaft elevator structure of Fig. 1, along A-A line cross section view;
Fig. 3 is that the C of arc frame of Fig. 1 is to view;
Fig. 4 is that the B of universal-joint lockout mechanism of Fig. 1 is to view.
Referring to Fig. 1, label declaration of the present utility model is as follows:
The 1-moving frame, 2-rotating handles, 3-lifting mechanism swivel nut, the 4-leading screw, 5-lifting mechanism fine-tuning nut, 6-differential assembly, 7-arc frame, 8-locating dowel pin, 9-leading screw groove, the 10-guide bolt, the 11-terminal pad, 12-connects the fine-tuning nut of lockout mechanism, 13-L type frame bar hole, 14-sliding wheel, 15-L type frame, 16-moving frame bar hole, 17-bolt, 18-ball.
The moving frame 1 of band wheel of the present utility model is provided with screw-threaded shaft elevator structure and L type movable device.Grow up to be a useful person before the assembly tearing differential open, rolling cart is pushed under the assembly that need tear open, rotary fine adjustment nut 5, make arc frame 7 consistent with the contour direction of differential assembly 6, rotate rotating handles 2, drive lifting nut 3, because of being provided with the guide bolt 10 that fixes with moving frame in the leading screw groove 9 on the leading screw, as shown in Figure 2, thereby leading screw makes vertical displacement movement, makes the cylindrical place of arc frame 7 upper surfaces and differential assembly 6 tangent up to adjusting to, the outerplanar at two locating dowel pins 8 and assembly cylindrical place near, as shown in Figure 3, at this moment, unclamp the nut of dowel bolt 17, mobile L type movable machine frame, spur slip wheel body 14 again and make the universal-joint terminal pad identical, allow the interior bolt of universal-joint stretch in the hole of the terminal pad 11 that fine-tuning nut 12 is regulated, behind fastening two bolts of nut with the universal-joint height.Nut 17 on the fastening again L type frame, at this moment, differential assembly 6 links into an integrated entity with rolling cart, during any one screw on tearing assembly open, can screw thread or Gask-O-Seal on the bolt be damaged to some extent because of the crooked of assembly.When pulling down all nuts of assembly, because of four sliding wheels 14 are bearing fit with L type frame, its gap is 0.1～0.2 millimeter, as shown in Figure 4, does not stick up the tail phenomenon so assembly is not bowed, under the drive of rotating handles 2, when making leading screw 4 oscilaltions, the assembly 6 that is fixed on the arc frame 7 is connected sliding wheel 14 synchronization liftings of channel-section steel one end together, thereby reaches the balance of lifting, assembly is not had at tool shop swing and the front and back play, guaranteed the dismounting quality greatly.When installation assembly, total adult is placed on the special vehicle, connect universal-joint and terminal pad 11, behind the nut 17 on the fastening again L type frame, rotate and fall nut 3, make the height that needs when being adjusted to installation assembly, parallel again pushing, all nuts on the fastening assembly, thus guaranteed setting accuracy.
Advantage of the present utility model is as follows:
1, the utility model is simple in structure, is easy to the one man operation and uses.
2, the utility model does not damage screw thread and ring washer, guarantees the installation accuracy of dismounting differential assembly And seal.
