By adopting the structure, the connecting rod 2 is sleeved in the through hole 53 of the differential shell 5, the head part 51 of the connecting rod can be inserted into the countersunk groove 11 of the base 1 to preliminarily position the differential shell 5, and meanwhile, the positioning block 12 is inserted into the positioning hole 52 of the differential shell 5, so that the positioning of the differential shell 5 is realized; after the connecting rod 2 is sleeved in the through hole 53 of the differential shell 5, the two ends of the differential shell 5 are limited by the limiting part 3 and the countersunk head groove 11 respectively, the differential shell 5 is fixed between the two, the clamping of the differential shell 5 is realized, the whole structure is simple, and the clamping and the dismounting of the differential shell 5 are convenient.
As can be understood with particular reference to fig. 1-3 in conjunction with fig. 4, fig. 4 is a top view of fig. 3.
The base 1 of the differential shell clamping tool can be of a disc-shaped structure, and the connecting rod 2 is vertically arranged at the center of the base. Specifically, the connecting rod 2 needs to pass through the through hole 53 of the differential case 5, and the through hole 53 of the differential case 5 also passes through the head 51, and at this time, the lower end of the connecting rod 2 needs to be located in the countersunk groove 11, which may correspond to the center position of the countersunk groove 11. The base 1 may be provided with one positioning block 12, so that the positioning block 12 corresponds to any one positioning hole 52 of the differential case 5, and certainly, more than one positioning block 12 may be provided along the circumferential direction of the base 1, corresponding to the corresponding number of positioning holes 52 of the differential case 5.
The base 1 and the connecting rod 2 can be fixed by split type fixed connection, or the base 1 and the connecting rod 2 can be integrally arranged, the connection mode of the base 1 and the connecting rod 2 is not limited in the utility model, and the base 1 and the connecting rod 2 can be fixedly connected by welding, threaded connection, interference fit and the like, as long as the connecting rod 2 is fixed on the base 1. As shown in fig. 1, the base 1 is provided with a through hole along the height direction thereof, the hole of the base 1 is a stepped hole and comprises a big hole and a small hole which are connected up and down, the big hole is the countersunk groove 11, the small hole is a threaded hole, and the lower end of the connecting rod 2 is connected with the small hole in a threaded manner, so that the connection is simple, and the processing of the base 1 is also convenient. In addition, as shown in fig. 1, the base 1 is provided with a connecting hole, the positioning block 12 can be inserted into the connecting hole to fix the base 1, and the insertion connecting hole may be, for example, a threaded connection, a latch connection, or the like, and may also be integrally provided with the base 1.
It will be appreciated that the connecting rod 2 needs to be able to pass through the through hole 53 of the differential case 5 and therefore has a diameter smaller than that of the through hole 53, and likewise, the countersunk groove 11 needs to be able to receive the head 51 of the differential case 5 therein and therefore has a size larger than that of the head 51 or slightly larger than that of the head 51 to position the differential case 5 through the head 51.
The specific structure and arrangement form of the limiting part 3 are not limited in the utility model, as long as the limiting part can be matched with the countersunk groove 11 to fix the differential case 5 between the limiting part and the countersunk groove. For example, in the present embodiment, the stopper 3 is a nut, the connecting rod 2 has an external thread section 21 at the tip thereof, and the nut is slidable on the external thread section 21 to restrict the differential case 5 between the nut and the base 1.
Of course, except the structure and the setting form that this embodiment adopted, also adopt other structures and setting forms, if set up spacing portion 3 into with 1 elastic connection of base and detachable stopper, will be poor shell 5 cover locate connecting rod 2 after, with stopper and 1 elastic connection of base, the stopper can receive the spring action, will be poor shell 5 is fixed in between stopper and the base 1.
This embodiment still includes fixture block 4, fixture block 4 is annular fixture block to seted up the breach, when connecting rod 2 was located to poor shell 5 cover, fixture block 4 can clamp connecting rod 2 with its breach, and was located between poor shell 5 and the spacing portion 3, thereby spacing portion 3 can push down fixture block 4 and carry on spacingly to poor shell 5, then the operation of spacing portion 3 can not cause the influence to the top of poor shell 5, reach the purpose of protecting poor shell 5, of course, spacing portion 3 directly the lower pressure shell 5 also can.
Referring to fig. 3, the diameter of the locking block 4 is larger than the diameter of the through hole 53 of the differential case 5, that is, the locking block can partially abut against the upper edge of the through hole 53 to press the differential case 5 to the lower side, so that the diameter of the limiting portion 3 can be smaller than the diameter of the through hole 53, when the locking block 4 is clamped between the limiting portion 3 and the differential case 5, the differential case 5 cannot be separated from the upper side of the connecting rod 2, when the locking block is disassembled, the limiting portion 3 is loosened, and the locking block 4 is removed, so that the differential case 5 can be disassembled.
Further, the corners of the latch 4 may be chamfered. When the clamping block 4 is clamped between the limiting part 3 and the differential shell 5, the edge angle of the clamping block cannot damage the differential shell 5 or the limiting part 3.
In addition, the structure of the fixture block 4 is not limited in the present invention, and in this embodiment, an annular structure with a notch is adopted because the structure is relatively simple to manufacture, relatively low in cost, and relatively stable in clamping effect, and in practical application, other structures may be adopted, for example, a semicircular structure or a triangular structure which is provided with a notch or can be clamped on the connecting rod 2 through other structures, so long as it can be clamped between the limiting portion 3 and the differential shell 5, and the differential shell 5 is fixed between the fixture block 4 and the base 1.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that it is obvious to those skilled in the art that various modifications and improvements can be made without departing from the principle of the present invention, and these modifications and improvements should also be considered as the protection scope of the present invention.
