Technical Field

[0001] The utility model relates to the technical field of oil pan assembly, and particularly relates to an oil pan assembly tooling and an oil pan assembly device. Background Technique

[0002] The oil pan refers to the bottom component of the engine and is tightly connected to the engine body. It is a sealed container used to hold engine oil and protect the internal components of the engine. It has various channels and holes to ensure the normal operation of the engine lubrication system. At the same time, the oil pan can also provide structural support to protect the stability and safety of the engine during operation.

[0003] During the assembly of the oil pan, it is necessary to first perform a glue-dotting operation on the connection surface where the oil pan is connected to the engine. After the glue-dotting is completed, it is connected to the engine body to achieve the assembly. However, the current oil pan assembly tooling has the technical problem that the surface of the oil pan may be scratched during the process of clamping the oil pan. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide an oil pan assembly tooling and an oil pan assembly device, aiming to solve the technical problem that the surface of the oil pan may be scratched during the process of clamping the oil pan by the current oil pan assembly tooling.

[0005] To achieve the above purpose, the oil pan assembly tooling proposed by the utility model includes:

[0014] Optionally, in an embodiment of the present invention, the vacuum suction cup is slidably connected to the chassis.

[0015] Optionally, in an embodiment of the present invention, it further includes a glue application assembly, and the glue application assembly is connected to the chassis.

[0016] Optionally, in an embodiment of the present invention, the glue application assembly includes:

[0019] A glue line detection camera, and the glue line detection camera is connected to the connecting frame.

[0020] Optionally, in an embodiment of the present invention, the connecting member is a spring floating connection seat.

[0021] Optionally, in an embodiment of the present invention, it further includes a positioning device, and the positioning device is connected to the chassis.

[0022] To achieve the above object, the present invention also proposes an oil pan assembly device, including the oil pan assembly tooling described above.

[0023] Optionally, in an embodiment of the present invention, there are two oil pan assembly toolings. Compared with the two oil pan assembly toolings, one has fewer vacuum suction cups and a larger adsorption area for each vacuum suction cup, and the other has more vacuum suction cups and a smaller adsorption area for each vacuum suction cup.

[0024] Compared with the prior art, the utility model can at least achieve the following beneficial effects. When the assembly tooling is working, the robotic arm is connected to the assembly tooling through a connecting piece. The robotic arm drives the assembly tooling to move to the corresponding position of the oil pan. The vacuum suction cup can correspond to and fit the groove position on the oil pan. The vacuum generation component is used to evacuate the space between the vacuum suction cup and the oil pan groove to create a vacuum, realizing the adsorption connection between the vacuum suction cup and the oil pan, and further realizing that the robotic arm drives the oil pan to move through the assembly tooling. Since the vacuum suction cup needs to deform during the adsorption process to adhere to the surface of the oil pan, the vacuum suction cups are made of relatively soft materials. Compared with the clamping jaw type assembly tooling, the vacuum suction cup will not cause scratches on the surface of the oil pan during the adsorption process, solving the technical problem that the current oil pan assembly tooling may scratch the surface of the oil pan during the clamping process. After the adsorption of the oil pan is completed, the robotic arm drives the oil pan to move for assembly with the engine block. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Referring to Figures 1 to 7 , the present utility model provides an oil pan assembly tooling, including:

[0042] A chassis 100;

[0043] A vacuum suction cup 200, which is located on one side of the chassis 100 and at least one is provided;

[0044] A vacuum generating assembly 300, the vacuum generating assembly 300 is located on the other side of the chassis 100, and the vacuum generating assembly 300 is connected to the vacuum suction cup 200;

[0045] A connecting member 400, the connecting member 400 and the vacuum generating assembly 300 are located on the same side of the chassis 100, and the connecting member 400 connects the chassis 100 and the robotic arm.

[0046] When this assembly tooling is working, the robotic arm is connected to this assembly tooling through the connecting member 400. The robotic arm drives this assembly tooling to move to the corresponding position of the oil pan 700. The vacuum suction cup 200 can correspond to and fit with the groove position on the oil pan. The vacuum generating assembly 300 evacuates the space between the vacuum suction cup 200 and the oil pan groove to create a vacuum, realizing the connection between the vacuum suction cup 200 and the oil pan, and further realizing that the robotic arm drives the oil pan to move through the assembly tooling. Since the vacuum suction cup 200 needs to deform during the adsorption process to adhere to the surface of the oil pan, the vacuum suction cup 200 is made of a relatively soft material. Compared with the jaw-type assembly tooling, the vacuum suction cup 200 will not cause problems such as scratching the surface of the oil pan during the adsorption process, solving the technical problem that the current oil pan assembly tooling may scratch the surface of the oil pan during the process of clamping the oil pan. After completing the adsorption of the oil pan, the robotic arm drives the oil pan to move for assembly with the engine block.

[0047] Specifically, the connecting member 400 is a spring floating connection seat. As the medium for connecting the robotic arm and the chassis 100, the spring floating connection seat has a certain floating movement function and elasticity by setting springs, preventing it from driving the chassis 100 too close to the oil pan during the adsorption process of the oil pan, thus causing wear and scratches between the two.

[0048] The vacuum suction cup 200 is slidably connected to the chassis 100. A guide rail 120 structure is provided on the chassis 100, and the vacuum suction cup 200 is slidably connected to the guide rail 120, enabling the vacuum suction cup 200 to slide relative to the chassis 100. Currently, the engine assembly workshop usually has mixed assembly of multiple models, so this assembly tooling needs to be applied to oil pans of different models. By designing the vacuum suction cup 200 as a sliding structure, when assembling oil pans of different models, the position of the vacuum suction cup 200 can be slid to adsorb different positions of the oil pan, meeting the adsorption and subsequent assembly requirements for different types of oil pans.

[0049] In addition, the number of vacuum suction cups 200 can be determined according to the specific type of oil pan to be assembled. Since the structures and volumes of oil pans of different models are different, their production methods are also different. Some oil pans have a relatively smooth surface, while some have a relatively rough surface. When adsorbing an oil pan with a relatively smooth surface, a vacuum suction cup 200 with a larger adsorption area can be selected. When adsorbing an oil pan with a relatively rough surface, due to the large surface unevenness, there is likely to be a gap between the two when using a vacuum suction cup with a larger area, affecting the adsorption effect. Therefore, in this case, a vacuum suction cup 200 with a smaller adsorption area can be selected, and the number of suction cups arranged can be increased to ensure the adsorption effect.

[0050] Furthermore, a soft sponge 110 is provided on the periphery of the chassis 100. During the process of the vacuum suction cup 200 adsorbing the oil pan, the chassis 100 will gradually approach the oil pan. The chassis 100 is made of metal, and when the chassis 100 comes into contact with the oil pan, it may cause scratches on the surface of the oil pan. To prevent this problem, a soft sponge 110 is provided on the periphery of the chassis 100 to prevent the chassis 100 from contacting the oil pan and damaging the oil pan.

[0051] Furthermore, the vacuum generating assembly 300 includes:

[0052] A vacuum generator 310, which is connected to the vacuum suction cup 200;

[0053] A PLC timing device 320, which is communicatively connected to the vacuum generator 310, and the PLC timing device 320 controls the vacuum generator 310 to evacuate the vacuum suction cup 200 at least twice.

[0054] During the operation of this assembly tooling, the adsorption stability determines the operation stability of the tooling. As a metal component, the oil pan has a relatively large mass. Therefore, it is necessary to ensure the vacuum degree between the vacuum chuck 200 and the oil pan. Compared with the single-stage vacuum pumping process, the multi-stage vacuum pumping operation can further reduce the residual gas between the vacuum chuck 200 and the oil pan on the basis of single-stage vacuum pumping, improve the adsorption strength of the vacuum chuck 200 for the oil pan, and prevent the oil pan from falling during the assembly process of the oil pan or the problem of inaccurate assembly between the two due to shaking during the engagement process with the engine block.

[0055] As an important component of the engine, the oil pan functions to store lubricating oil (engine oil). Therefore, during the assembly process of the oil pan and the engine block, it is necessary to ensure the sealing performance at the connection between the two. Applying glue at the connection can improve the sealing performance. In addition, the glue can fill the tiny gaps or unevenness that may occur during the assembly process of the two, making the assembly between the two more tight and reliable. To improve the assembly continuity, the assembly tooling is also provided with a glue application component 500.

[0056] Specifically, the glue application component 500 includes: a connecting frame 510, a glue application structure 520, and a glue line detection camera 530.

[0057] The connecting frame 510 serves as the bearing structure for the glue application structure 520 and the car body detection camera, and is connected to the chassis 100.

[0058] Before assembly, the robotic arm first drives the glue application structure 520 towards the connection surface of the oil pan and performs a glue application action along a predetermined trajectory on this connection surface. The glue line detection camera 530 identifies the model of the oil pan and detects the glue application quality. After the glue application action is completed, the robotic arm drives the chassis 100 to move and perform an adsorption action. After the adsorption is completed, the oil pan is lifted to engage with the engine block, completing the assembly between the two.

[0059] Furthermore, the assembly tooling further includes a positioning device 600, which can assist the robotic arm in adsorbing the oil pan and performing precise assembly.

[0060] Refer to Figure 8 , to achieve the above object, the present utility model also proposes an oil pan assembly device, which includes the oil pan assembly tooling described above. Since this oil pan assembly device adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, and will not be elaborated here one by one.

[0061] In a preferred embodiment of the oil pan assembly device, two oil pan assembly toolings are connected to the same robotic arm. The specifications of the two toolings are different. One has a layout structure of vacuum suction cups 200 with a smaller number of suction cups but a larger adsorption area for each suction cup, which is used to adsorb the oil pan with a relatively smooth surface; the other has a layout structure of vacuum suction cups 200 with a larger number of suction cups but a smaller adsorption area for each suction cup, which is used to adsorb the oil pan with a relatively rough surface. Different specifications of assembly toolings are used when assembling oil pans of different models to achieve the mixed assembly of oil pans of multiple models.

[0062] The above are only alternative embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
