[0029] See also Figure 1 to Figure 2 , the embodiment of the utility model provides a positioning device for a differential housing, which includes:

[0030] Bottom plate 1;

[0031] The positioning mechanism comprises two positioning plates 2 arranged on the bottom plate 1, and positioning pins 3 are arranged on the two positioning plates 2, wherein at least one positioning plate 2 is a movable positioning plate movably arranged on the bottom plate 1;

[0032] The adjusting mechanism 4 includes the same number of adjusting components as the movable positioning plate, the adjusting components include an adjusting rod 402, a driving rod 401 and a connecting rod 403, the first end of the adjusting rod 402 is hinged to the movable positioning plate, the second end of the adjusting rod 402 is hinged to the first end of the driving rod 401, the first end of the connecting rod 403 is hinged to the middle of the adjusting rod 402, and the second ends of the driving rod 401 and the connecting rod 403 are both hinged to the bottom plate 1;

[0033] The driving mechanism 5 is used to drive the driving rod 401 to rotate around its second end.

[0034] The positioning device provided in this embodiment, when in use, drives the driving rod 401 to swing around its second end through the driving mechanism 5. Since the second end of the adjusting rod 402 is hinged to the driving rod 401, the middle part of the adjusting rod 402 is hinged and limited by the connecting rod 403, and the first end of the adjusting rod 402 is hinged and limited to the movable positioning plate, and the movable positioning plate is moved and limited on the bottom plate 1. Therefore, when the driving rod 401 swings, it can drive the first end of the adjusting rod 402 to make horizontal movement, and then drive the movable positioning plate to make horizontal movement, so as to adjust the position of the positioning pin 3 until the two positioning pins 3 match the positions of the two positioning pin 3 holes on the differential case.

[0035] In this embodiment, a movable active positioning plate is provided, and the position of the movable positioning plate is adjusted by an adjusting mechanism 4, so that the distance between the two positioning pins 3 of the device can be adjusted according to the specifications of the differential housing, thereby meeting the positioning requirements of differential housings of different specifications and models. It has good versatility, does not require complicated operating steps, and is more operable.

[0036] The various components of the positioning device provided by the embodiment of the utility model are described in detail below with reference to the accompanying drawings.

[0037] In this embodiment, the base plate 1 is used to provide support for the components of the positioning device, and it can be any suitable structural form, for example, see Figure 1 In this embodiment, the base plate 1 can be a rectangular plane plate, and the positioning mechanism, the adjustment mechanism 4 and the driving mechanism 5 are all arranged on the base plate 1.

[0038] More specifically, see Figure 1 In this embodiment, a groove 101 is provided on the surface of the bottom plate 1, and the positioning mechanism, the adjustment mechanism 4 and the driving mechanism 5 are all provided in the groove 101 of the bottom plate 1. The groove 101 is provided to accommodate various components, which makes it easier to install and position the components. For example, the side of the positioning plate 2 can be fitted with the side of the groove 101, so that the installation of the positioning plate 2 is positioned through the groove 101, and the side of the groove 101 can also provide a certain guide for the movement of the movable positioning plate.

[0039] See also Figure 1 In this embodiment, both positioning plates 2 can be set as rectangular plates, and at least one of the two positioning plates 2 is a movable positioning plate movably set on the bottom plate 1. Through this structural setting, the position of the movable positioning plate can be adjusted to achieve the adjustment of the distance between the two positioning plates 2, and the adjustment of the relative positions of the two positioning pins 3 can be achieved to meet the positioning of differential housings of different specifications and models.

[0040] For example, in some embodiments, the two positioning plates 2 can be, one positioning plate 2 is fixedly set on the base plate 1, and the other positioning plate 2 is movably set on the base plate 1, and only one corresponding adjustment component is required. In this way, the relative positions of the two positioning pins 3 can be adjusted by adjusting the position of one positioning plate 2.

[0041] See also Figure 1 In this embodiment, it is preferred that both positioning plates 2 are movable positioning plates, that is, both positioning plates 2 can be movably arranged on the base plate 1. With such an arrangement, the relative positions of the two positioning pins 3 can be adjusted by synchronously adjusting the positions of the two positioning plates 2.

[0042] Specifically, participate in Figure 1 and Figure 2 A guide groove 102 extending along the length direction of the bottom plate 1 is arranged in the groove 101 of the bottom plate 1, and a guide block 103 matching the guide groove 102 is arranged on the bottom surface of the two positioning plates 2. The guide block 103 is slidably installed in the guide groove 102. In this way, the positioning plate 2 can be moved by the guide block 103 cooperating with the guide groove 102. The structure is simple and easy to implement.

[0043] See also Figure 1 In this embodiment, a support plate 201 is vertically arranged on the side where the two positioning plates 2 are close to each other. The two support plates 201 are arc-shaped plates with the middle part recessed in the direction away from each other, and the two positioning pins 3 are respectively arranged in the middle part of the top surface of the two support plates 201. In this arrangement, the arc-shaped support plate 201 can not only ensure that the support plate 201 and the differential housing have sufficient contact area, and ensure the support stability of the support plate 201 to the differential housing, but also the two support plates 201 are arranged vertically, so that there is a certain accommodation space between the two, which is convenient for accommodating the protruding part of the bottom of the differential housing, matching with the outer envelope of the differential housing, and avoiding structural interference between the differential housing and the positioning plate 2, the bottom plate 1, etc.

[0044] See also Figure 1In this embodiment, the lengths of the two locating pins 3 are one long and one short, that is, the length of one of the locating pins 3 is greater than the length of the other locating pin 3. Based on this structural design, when placing the differential case, one pin hole of the differential case can be firstly put on the longer locating pin 3, and then the distance between the two locating plates 2 can be adjusted to make the differential case move synchronously with one of the locating plates 2 until the other pin hole of the differential case is aligned with the shorter locating pin 3, and then the differential case is lowered vertically to make the other pin hole of the differential case put on the shorter locating pin 3. In this way, the positioning operation of the differential case can be simpler, more convenient and more operable.

[0045] Furthermore, in this embodiment, the two positioning pins 3 are detachably arranged on the support plate 201. For example, the support plate 201 is provided with a pin hole, and the positioning pin 3 is detachably inserted into the pin hole. In this way, the positioning pin 3 on the support plate 201 can be replaced according to the use requirements. By installing positioning pins 3 of different specifications on the support plate 201, the positioning requirements of the pin holes of the differential housings of different specifications can be met, thereby increasing the versatility of the positioning device.

[0046] In this embodiment, the adjustment mechanism 4 is used to adjust the position of the movable positioning plate, and it includes adjustment components that are consistent with the number of movable positioning plates. For example, corresponding to the setting of the above-mentioned two movable positioning plates, there are also two adjustment components, which are symmetrically arranged on the left and right and are respectively used to adjust the two movable positioning plates.

[0047] Specifically, see Figure 1 and Figure 2 In this embodiment, each adjustment component includes an adjustment rod 402, a driving rod 401 and a connecting rod 403, wherein the adjustment rod 402 is a bent rod bent from the middle, the driving rod 401 and the connecting rod 403 are both straight rods, the first end of the adjustment rod 402 is hinged to the positioning plate 2, the second end of the adjustment rod 402 is hinged to the first end of the driving rod 401, the first end of the connecting rod 403 is hinged to the middle of the adjustment rod 402, and the second ends of the driving rod 401 and the connecting rod 403 are both hinged to the bottom plate 1. Based on this structural design, when the driving rod 401 rotates around its second end, the positioning plate 2 can be driven to move horizontally through the adjustment rod 402 to adjust the position of the positioning plate 2. This design has a simple structure and is easy to operate. It should be noted that the hinges of the various rods involved in this embodiment are all hinged through pins.

[0048] See also Figure 1In this embodiment, a spacer 6 is provided between the bottom plate 1 and the two positioning plates 2. The length of the spacer 6 is less than the length of the positioning plate 2, so that there is space for installing the adjustment rod 402 below the front end of the positioning plate 2. In this way, by providing the spacer 6, there is a movable space between the positioning plate 2 and the bottom plate 1, and the movable space facilitates the second end of the adjustment rod 402 to extend to the bottom of the front end of the positioning plate 2 and connect with the bottom surface of the positioning plate 2.

[0049] More specifically, in this embodiment, the pad 6 can be fixed on the bottom plate 1, or fixed on the bottom surface of the positioning plate 2. For example, when the pad 6 is fixed on the bottom plate 1, the positioning plate 2 can be directly placed on the pad 6; for example, when the pad 6 is fixed on the bottom surface of the positioning plate 2, the positioning plate 2 can drive the pad 6 to move along the bottom plate 1.

[0050] In this embodiment, the driving mechanism 5 is used to drive the two adjustment components to make the two positioning plates 2 move synchronously to adjust the relative positions of the two positioning pins 3. Figure 1 and Figure 2 The driving mechanism 5 includes a driving gear 501, which is rotatably mounted on the base plate 1. The second ends of the driving rods 401 of the two adjustment components are fixedly connected to passive gears 502. The two passive gears 502 are rotatably mounted on the base plate 1, and the two passive gears 502 are meshed with each other, and one of the passive gears 502 is meshed with the driving gear 501.

[0051] Based on the above structural design, when the driving gear 501 rotates, it can drive the passive gear 502 meshing with it to rotate. Since the two passive gears 502 are meshing with each other, the other passive gear 502 will also rotate, and the rotation directions of the two passive gears 502 are opposite. Therefore, the two passive gears 502 can drive the two driving rods 401 to swing in opposite directions, that is, one driving rod 401 swings counterclockwise and the other driving rod 401 swings clockwise, thereby driving the two positioning plates 2 to move in opposite directions, that is, the two positioning plates 2 move closer to or farther away from each other, thereby realizing the adjustment of the position of the positioning pin 3.

[0052] See also Figure 1 and Figure 2 In this embodiment, a manual rocker 503 is also provided on the driving gear 501. The manual rocker 503 is in a "Z" shape. By rotating the manual rocker 503, the driving gear 501 can be driven to rotate, thereby realizing the driving of the adjustment mechanism 4.

[0053] In some embodiments, the driving gear 501 is detachably rotatably mounted on the bottom plate 1. For example, a pin hole is provided on the bottom plate 1, a pin shaft is provided at the center of the driving gear 501, and the driving gear 501 is installed on the bottom plate 1 by inserting the pin shaft into the pin hole. In this way, after the differential housing is positioned, the driving gear 501 can be removed to remove the manual rocker 503 fixed to the driving gear 501, thereby freeing up more assembly operation space and facilitating the assembly of the differential.

[0054] In other embodiments, the manual rocker 503 is detachably fixed to the driving gear 501. For example, a square hole is provided at the center of the driving gear 501, and the lower end of the manual rocker 503 is also correspondingly provided in a square shape, so that the manual rocker 503 can be installed on the driving gear 501 by plugging. In this way, after the differential housing is positioned, the manual rocker 503 can be removed, thereby freeing up more assembly operation space and facilitating the assembly of the differential.

[0055] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
