Description

Technical Field

[0001] The utility model relates to the technical field of gearbox assembly auxiliary tools, and more specifically, to a handling and positioning tooling for an oil pan. Background Art

[0002] In the current gearbox assembly production line, the installation process of the oil pan is as follows: ① Use an off-line automatic glue applicator to automatically apply glue to the oil pan; ② Manually pick up the glued oil pan and place it beside the gearbox housing; ③ Place the oil pan on the gearbox housing, and at the same time align the installation holes of the oil pan with the threaded holes of the gearbox housing; ④ Install bolts to fix the oil pan to the gearbox housing.

[0003] In the above steps ② and ③, when manually holding the glued oil pan for handling and positioning, the fingers are likely to touch the glued surface of the oil pan. If the glue is knocked off, it will affect the sealing performance of the gearbox and cause oil leakage problems. Especially in step ③, it is necessary to place the oil pan on the gearbox housing with both hands buckling the glued surface. When the oil pan is about to contact the gearbox housing, the fingers need to be withdrawn, and both hands are extremely likely to touch the glue.

[0004] Relevant research has been carried out in the prior art. For example, Chinese Patent Publication No. CN213064232U discloses an oil pan installation guide pin. When installing the oil pan, first insert the guide pin into the bolt hole of the gearbox housing, and then pass the installation hole of the oil pan through the guide pin correspondingly to achieve positioning, solving the positioning problem in the above step ③. However, since the oil pan needs to be held by hand during the handling and installation process, there is still a problem of knocking off the glue. At the same time, it is necessary to insert multiple positioning pins into the gearbox housing before placing the oil pan, resulting in low work efficiency. Summary of the Utility Model

[0005] In order to overcome the problem that the glue is easily knocked off during the handling and installation of the oil pan in the above prior art, the utility model provides a handling and positioning tooling for an oil pan, which can not only avoid the problem of poor sealing caused by the glue being knocked off by hand, but also improve the work efficiency.

[0006] To solve the above technical problems, the technical solution adopted by the utility model is: a handling and positioning tooling for an oil pan, including an installation handle, the installation handle is connected with at least two positioning pins, the outer diameter size of the positioning pins matches the inner diameter size of the installation holes of the oil pan, each of the positioning pins is arranged in parallel in the same direction, and each of the positioning pins corresponds to different installation hole positions of the oil pan respectively.

[0007] In the technical solution of this utility model, the locating pins of the mounting handle are simultaneously inserted into the corresponding mounting holes of the glued oil pan. With a slight tilt, the oil pan can be lifted and transported. Since the tooling contacts the mounting holes only through the locating pins, the glued surface of the oil pan is not damaged, preventing poor sealing after the oil pan is installed. After the oil pan is moved to the assembly station, it needs to be installed on the component to be assembled. The operator can align the locating pins with the bolt holes of the component to be assembled, thereby aligning the mounting holes of the oil pan with the bolt holes. Since there are at least two locating pins, each of which aligns with the bolt holes and the mounting holes, each mounting hole of the oil pan can be aligned with the corresponding bolt hole. Finally, the tooling is removed and the oil pan can be secured to the component to be assembled using bolts. The oil pan can be transported and positioned using only the tooling, which is simple and efficient. It also does not damage the glued surface of the oil pan, preventing poor sealing after installation.

[0008] Furthermore, the locating pin includes a first locating section and a second locating section, one end of the first locating section is connected to the mounting handle, the other end of the first locating section is connected to one end of the second locating section, the diameter of the second locating section is smaller than the diameter of the first locating section, and the outer diameter of the first locating section matches the inner diameter of the mounting hole of the oil pan.

[0009] In this solution, the second positioning section is used to be inserted into the bolt hole of the component to be assembled, and the first positioning section is used to abut against the outside of the bolt hole. The oil pan is sleeved on the first positioning section to facilitate positioning and installation of the oil pan.

[0010] Furthermore, an end of the second positioning segment away from the first positioning segment is provided with a conical chamfer.

[0011] In this solution, a conical chamfer is provided to facilitate insertion of the positioning pin into the mounting hole.

[0012] Furthermore, the positioning pin is detachably connected to the mounting handle.

[0013] In this solution, the positioning pins are detachably connected to the mounting handle, so that the number of positioning pins to be set can be adjusted and the required positioning pins can be set accordingly.

[0014] Furthermore, the mounting handle is connected to two positioning pins, and the two positioning pins respectively correspond to two adjacent mounting holes of the oil pan.

[0015] In this solution, two positioning pins correspond to two adjacent mounting holes, which can effectively position the oil pan and make the tooling structure compact and easy to grasp by hand.

[0016] Further, the installation handle is a telescopic structure to adjust the distance between the two positioning pins.

[0017] In this solution, since the installation handle can be telescopically adjusted, the distance between the two positioning pins can be adjusted, enabling the tooling to be applicable to different models of oil pans or different installation hole positions of the same oil pan.

[0018] Further, the installation handle includes a first component and a second component. The two positioning pins are respectively connected to the first component and the second component. The first component is provided with a slot, and the second component is provided with an insertion bar. The insertion bar is inserted into the slot to adjust the distance between the two positioning pins.

[0019] In this solution, by inserting the insertion bar into the slot, the relative positions of the first component and the second component can be adjusted, thereby adjusting the distance between the two positioning pins to be applicable to different models of oil pans.

[0020] Further, the installation handle further includes an adjusting member. One end of the adjusting member is connected to the slot, and the other end of the adjusting member is adjustably connected to the insertion bar.

[0021] In this solution, the relative positions of the first component and the second component can be adjusted through the adjusting member, and the positions of the first component and the second component can also be locked.

[0022] Further, the adjusting member is a threaded rod. A threaded hole is formed in the side wall of the slot. The threaded rod is threadedly connected to the threaded hole. One end of the threaded rod located inside the slot abuts against the insertion bar.

[0023] In this solution, one end of the threaded rod abuts against the insertion bar to lock the first component and the second component. When adjustment is needed, the threaded rod can be loosened, the insertion depth of the insertion bar in the slot can be adjusted, and then the threaded rod can be tightened again.

[0024] Further, the adjusting member is a worm. An installation groove is formed in the side wall of the slot. The worm is rotatably connected in the installation groove. The insertion bar is fixedly connected with a rack, and the worm meshes with the rack.

[0025] In this solution, by screwing the worm, the rack moves, thereby adjusting the relative positions of the first component and the second component.

[0026] Compared with the prior art, the beneficial effects of the present utility model are:

[0027] 1. For the tooling of the present utility model, since the tooling only contacts the mounting holes through the positioning pins, the gluing surface of the oil pan will not be damaged, preventing poor sealing after the installation of the oil pan.

[0037] The technical solution of the present utility model will be further specifically described below through specific embodiments in conjunction with the attached drawings:

[0038] Embodiment 1

[0039] Reference Figure 1 , this embodiment discloses a handling and positioning tooling for an oil pan, which includes a mounting handle 1. The mounting handle 1 is connected with at least two positioning pins 2. The outer diameter dimension of the positioning pin 2 matches the inner diameter dimension of the mounting hole of the oil pan. Each positioning pin 2 is arranged in parallel in the same direction, and each positioning pin 2 corresponds to a different mounting hole position of the oil pan respectively.

[0040] In the technical solution of the present utility model, each positioning pin 2 of the mounting handle 1 is respectively inserted into different mounting holes of the oil pan coated with glue, and the oil pan can be lifted and carried by tilting slightly. Since the tooling only contacts the mounting hole through the positioning pin 2, the coated surface of the oil pan will not be damaged, preventing poor sealing after the oil pan is installed. After the oil pan is transferred to the assembly station to be assembled, it is also necessary to further install the oil pan on the component to be assembled. The operator can align the positioning pin 2 with the bolt hole of the component to be assembled, so that the mounting hole of the oil pan is aligned with the bolt hole. Since there are at least two positioning pins 2 and they are all aligned with the bolt hole and the mounting hole, each mounting hole of the oil pan can be respectively aligned with the corresponding bolt hole. Finally, after taking out the tooling, the oil pan can be fixed on the component to be assembled through bolts. The handling and positioning process of the oil pan can be realized only by using the tooling, with simple operation, high working efficiency, and without damaging the coated surface of the oil pan, avoiding the problem of poor sealing after installation.

[0041] Reference Figure 1In this embodiment, the locating pin 2 includes a first locating section 21 and a second locating section 22. One end of the first locating section 21 is connected to the mounting handle 1, and the other end of the first locating section 21 is connected to one end of the second locating section 22. The diameter of the second locating section 22 is smaller than that of the first locating section 21, and the outer diameter of the first locating section 21 matches the inner diameter of the oil pan mounting hole. Specifically, the second locating section 22 is inserted into the bolt hole of the component to be assembled, while the first locating section 21 is designed to abut the outside of the bolt hole. The oil pan is then fitted onto the first locating section 21, facilitating its positioning and installation.

[0042] When the operator uses the tooling of this embodiment to transport the oil pan, he first passes the second positioning section 22 through the glue-coated oil pan, and matches the mounting hole of the oil pan to the first positioning section 21. The operator lifts the oil pan to be transported to the designated installation station, then inserts the second positioning section 22 into the bolt hole of the component to be assembled, and finally pushes the oil pan from the first positioning section 21 to the second positioning section 22, so that the tooling can be withdrawn from the mounting hole of the oil pan, thereby completing the transportation and positioning of the oil pan.

[0043] refer to Figure 1 The second positioning section 22 has a conical chamfer 23 at one end away from the first positioning section 21. The conical chamfer 23 is provided at the end of the second positioning section 22. When the second positioning section 22 needs to be inserted into the mounting hole, the conical chamfer 23 can serve as a guide, so that each positioning pin 2 can be inserted into a different mounting hole at the same time.

[0044] In this embodiment, the positioning pin 2 is preferably detachably connected to the mounting handle 1. In this embodiment, an external thread may be provided on the end of the positioning pin 2 proximate to the mounting handle 1. A threaded hole is provided in the mounting handle 1 where the positioning pin 2 is mounted. The positioning pin 2 is threadedly connected to the threaded hole to achieve a detachable connection between the positioning pin 2 and the mounting handle 1. The detachable connection between the positioning pin 2 and the mounting handle 1 facilitates adjustment of the number of positioning pins 2 provided, allowing the desired number or positions of positioning pins 2 to be provided according to actual needs.

[0045] In some optional embodiments, the mounting handle 1 is provided with a plurality of threaded holes for connecting to the mounting handle 1 , with the threaded holes being distributed in parallel at different positions on the mounting handle 1 . Different combinations of threaded hole positions correspond to different oil pan mounting hole positions, allowing the operator to adjust the installation position and number of locating pins 2 according to actual needs, making the tooling adaptable to different oil pan models.

[0046] In this embodiment, the installation handle 1 is connected with two positioning pins 2, and the two positioning pins 2 respectively correspond to the positions of two adjacent mounting holes of the oil pan. By corresponding the two positioning pins 2 to two adjacent mounting holes, the oil pan can be effectively positioned. At the same time, since the positions of the adjacent mounting holes are not too far apart, the size of the installation handle 1 is not too large either, so that the tooling structure is compact and more convenient to hold by hand. Of course, in other embodiments, the number of the positioning pins 2 can be set to three, four or more according to requirements.

[0047] Embodiment 2

[0048] Reference Figure 2 and Figure 3 This embodiment is similar to Embodiment 1, the difference is that in this embodiment, the installation handle 1 is a telescopic structure to adjust the distance between the two positioning pins. Since the installation handle 1 can be telescopically adjusted, the distance between the two positioning pins 2 can be adjusted, so that the tooling can be applied to oil pans of different models or different mounting hole positions of the same oil pan.

[0049] In this embodiment, the installation handle 1 includes a first component 11 and a second component 12. The two positioning pins 2 are respectively connected to the first component 11 and the second component 12. The first component 11 is provided with a slot 111, and the second component 12 is provided with an insertion bar 121. The insertion bar 121 is inserted into the slot 111 to adjust the distance between the two positioning pins. By inserting the insertion bar 121 into the slot 111, the relative positions of the first component 11 and the second component 12 can be adjusted, so as to adjust the distance between the two positioning pins 2, and the tooling can be applied to oil pans of different models.

[0050] In some alternative embodiments, through the tight fit between the insertion bar 121 and the slot 111, the insertion bar 121 will not become loose after being inserted into the slot 111. A material with certain flexible deformation ability, such as rubber material, can be selected to cover the surface of the insertion bar 121.

[0051] Reference Figure 2 and Figure 3 In this embodiment, the installation handle 1 further includes an adjusting member. One end of the adjusting member is connected to the slot 111, and the other end of the adjusting member is adjustably connected to the insertion bar 121. Through the adjusting member, the relative positions of the first component 11 and the second component 12 can be adjusted, and at the same time, the positions of the first component 11 and the second component 12 can be locked.

[0052] More specifically, the adjusting member in this embodiment is a threaded rod 13. Threaded holes are formed in the side wall of the slot 111, and the threaded rod 13 is threadedly connected to the threaded holes. One end of the threaded rod 13 located inside the slot 111 abuts against the insertion strip 121. The abutment of one end of the threaded rod 13 against the insertion strip 121 can lock the first component 11 and the second component 12. When adjustment is required, the threaded rod 13 can be loosened, and after adjusting the insertion depth of the insertion strip 121 in the slot 111, the threaded rod 13 can be tightened again.

[0053] Embodiment 3

[0054] Reference Figure 4 And Figure 5 This embodiment is similar to Embodiment 2. The difference is that the adjusting member in this embodiment is a worm 14. An installation groove is formed in the side wall of the slot 111, and the worm 14 is rotatably connected in the installation groove. A rack 15 is fixedly connected to the insertion strip 121, and the worm 14 meshes with the rack 15. By screwing the worm 14, the rack 15 is moved, so as to adjust the relative positions of the first component 11 and the second component 12.

[0055] In this embodiment, rotating shafts are provided at both ends of the worm 14, and rotating shaft grooves are formed in the corresponding two side walls of the installation groove. The rotating shafts at both ends are rotatably placed in the rotating shaft grooves. The worm 14 is rotatably connected in the installation groove and partially exposed outside the installation groove, so as to facilitate manually rotating the worm 14. The rack 15 is fixedly connected to the side of the insertion strip 121 facing the worm 14, and teeth are provided at the part where the upper side of the rack 15 meshes with the worm 14. The length direction of the rack 15 is consistent with the insertion direction of the first component 11 and the second component 12. In some embodiments, the rack 15 can be integrally formed with the insertion strip 121. The adjustment principle of this embodiment is similar to the rack 15 and worm 14 structure of an adjustable wrench.

[0056] It can be understood that by setting appropriate helix angles and friction angles for the rack 15 and the worm 14, self-locking can be formed, so as to prevent the positioning pin 2 from shifting after being locked.

[0057] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here.
