Description

Technical Field

[0001] The utility model belongs to the technical field of automobile manufacturing and assembly, and specifically relates to an oil pan assembly tooling. Background Art

[0002] With the development of automobile engine assembly technology, the assembly process of the oil pan is gradually developing towards automation and high efficiency. However, in actual production, there are still some problems with the existing oil pan assembly tooling. For example, some tooling designs are complex and inconvenient to operate, resulting in low assembly efficiency. At the same time, during the assembly process, high requirements are placed on the positioning accuracy, but existing equipment often struggles to meet the high-precision needs, thus affecting the overall assembly quality.

[0003] After retrieval, an oil pan and plug assembly machine with the publication number CN110385568B was disclosed, and the publication date was June 25, 2024. This design realizes the automatic assembly of the oil pan and the plug through components such as a sealing ring feeding and transferring mechanism, a plug feeding mechanism, and a positioning table. Although this device can improve the installation efficiency of the plug, there are still certain deficiencies in practical applications. Firstly, the design of its positioning system is relatively complex, requiring multiple independent mechanisms to work together, increasing the manufacturing cost and maintenance difficulty of the equipment. Secondly, since this device is mainly aimed at plug assembly, its functions are relatively single and cannot meet the diverse needs of the overall oil pan assembly. In addition, the positioning of this device for the oil pan relies on a fixed positioning table, lacking flexibility and being difficult to adapt to the assembly requirements of different models of oil pans.

[0004] After retrieval, an engine oil pan assembly system and an assembly method with the publication number CN108372401B were disclosed, and the publication date was June 16, 2020. This design uses a transportation unit, a gluing unit, a tightening unit, and a grasping mechanism to work together, enabling the simultaneous assembly of the oil pans of multiple engines, with a relatively high level of automation. However, this system also has problems in practical applications. Firstly, its structure is complex, occupies a large area, and has high requirements for the space of the production site, which is not conducive to the deployment of small factories or production lines. Secondly, although this system can achieve a certain degree of automatic assembly, its positioning accuracy for the oil pan depends on the cooperation of the transportation unit and the grasping mechanism. Once an error occurs in a certain link, it will directly affect the assembly quality. In addition, the flexibility of this system is limited, and it is difficult to quickly adapt to the assembly requirements of different specifications of oil pans, restricting its application scope in mixed-line production.

[0005] The above problems indicate that the existing oil pan assembly tooling in the market still lacks in terms of functional diversity and flexibility, and is difficult to fully meet the requirements of modern engine assembly processes for high efficiency, precision, and flexibility. Therefore, the utility model provides an oil pan assembly tooling to overcome these deficiencies and provide a more efficient, flexible, and adaptable solution. Utility Model Content

[0006] This utility model relates to an oil pan assembly fixture, including an assembly platform, a positioning adjustment component, and a flexible clamping component. The positioning adjustment component is installed on the top of the assembly platform, and the flexible clamping component is provided on one side of the assembly platform.

[0007] The positioning and adjustment assembly includes a drive motor, a transmission gear, a rack and pinion slide rail, a slider, a positioning plate, and an adjusting screw. A rack and pinion slide rail is symmetrically fixedly connected to the top of the assembly platform. A slider is slidably connected to the outer side of the rack and pinion slide rail. A positioning plate is fixedly connected to the top of the slider. An adjusting screw is threaded through the middle of the positioning plate, and one end of the adjusting screw is threadedly connected to the slider. A drive motor is embedded in one side of the assembly platform. A transmission gear is fixedly connected to the top of the output shaft of the drive motor, and the transmission gear meshes with the rack and pinion slide rail.

[0008] The flexible clamping assembly includes clamping cylinders, clamping arms, guide grooves, elastic pressure plates, buffer springs, and clamping pads. Clamping cylinders are symmetrically fixed to one side of the assembly platform. A clamping arm is fixedly connected to the output end of each clamping cylinder. A guide groove is formed on the inner side of the clamping arm. An elastic pressure plate is slidably connected inside the guide groove. A buffer spring is fixedly connected to one side of the elastic pressure plate, and the other end of the buffer spring is fixedly connected to the inner wall of the guide groove. A clamping pad is fixedly connected to the other side of the elastic pressure plate.

[0009] Preferably, the bottom of the assembly platform is symmetrically fixed with support columns, and the bottom end of the support columns is provided with shock-absorbing pads. The shock-absorbing pads are made of rubber and have a thickness of 10mm.

[0010] Preferably, the top of the positioning plate is provided with anti-slip texture, the anti-slip texture is distributed in a grid pattern, and the depth of the anti-slip texture is 0.5mm.

[0011] Preferably, the clamping pad is made of polyurethane material, and the surface of the clamping pad is provided with anti-slip protrusions. The diameter of the anti-slip protrusions is 2mm, and the anti-slip protrusions are evenly distributed on the surface of the clamping pad.

[0012] Preferably, the number of buffer springs is four, and the buffer springs are evenly distributed on one side of the elastic pressure plate.

[0013] Preferably, a control panel is provided on one side of the assembly platform, and operation buttons are distributed on the surface of the control panel. A PLC controller is integrated inside the control panel.

[0014] Preferably, the elastic pressure plate is connected to the inner wall of the guide groove via a buffer spring, the buffer spring being used to provide elastic force to adjust the position of the clamping pad.

[0015] In this invention, the positioning and adjusting assembly uses a drive motor to rotate a transmission gear, which meshes with a rack and pinion slide rail, thereby enabling the slider to move linearly along the rack and pinion slide rail. A positioning plate is fixedly attached to the top of the slider, and the position of the positioning plate can be finely adjusted using an adjusting screw to accommodate oil pans of different sizes. The top of the positioning plate is provided with anti-slip textures to effectively prevent the oil pan from sliding during assembly.

[0016] The flexible clamping assembly moves the clamping arm via a clamping cylinder. An elastic pressure plate is located on the inner side of the clamping arm, and one side of the pressure plate is connected to a guide groove via a buffer spring. When the clamping arm clamps the oil pan, the elastic pressure plate automatically adjusts its position according to the shape of the oil pan, ensuring a uniform distribution of clamping force. The clamping pad is made of polyurethane material with anti-slip protrusions on its surface, further enhancing clamping stability.

[0017] This invention solves the problems of complex design, inconvenient operation, and insufficient positioning accuracy of existing oil pan assembly fixtures by combining a positioning adjustment component and a flexible clamping component. The positioning adjustment component can quickly adjust the position of the positioning plate to adapt to different models of oil pans, improving assembly flexibility; the flexible clamping component, through the design of an elastic pressure plate and a buffer spring, avoids damage to the surface of the oil pan during clamping, while ensuring clamping stability.

[0018] Furthermore, the shock-absorbing pads at the bottom of the assembly platform effectively absorb vibrations during assembly, reducing noise during equipment operation and extending equipment lifespan. The PLC controller integrated into the control panel automates the entire assembly process, simplifying operations and improving assembly efficiency.

[0019] In summary, this utility model provides an efficient, flexible and adaptable oil pan assembly fixture that can meet the demands of modern engine assembly processes for high efficiency, precision and flexibility. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Specific implementation examples are given below.

[0027] This utility model relates to an oil pan assembly fixture, the structure of which is as follows: Figures 1 to 4 As shown, the assembly includes an assembly platform 1, a positioning and adjustment component 2, and a flexible clamping component 3. The positioning and adjustment component 2 is mounted on the top of the assembly platform 1, and the flexible clamping component 3 is provided on one side of the assembly platform 1. The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Assembly platform 1 is the basic component of the entire tooling. Four support columns 4 are symmetrically fixed to its bottom. Vibration damping pads 401 are installed at the bottom of each support column 4, and are bolted to the bottom of the support column 4. The vibration damping pads 401 are made of rubber and are 10mm thick; they contact the ground to absorb vibrations generated during assembly. A control panel 5 is also installed on one side of assembly platform 1. The surface of the control panel 5 is distributed with operation buttons 501, and it integrates a PLC controller 502. The elastic pressure plate 304 is connected to the inner wall of the guide groove 303 via a buffer spring 305, which provides elastic force to adjust the position of the clamping pad 306.

[0029] The operation button 501 is used to input control commands. After receiving the commands, the PLC controller 502 outputs signals to drive the positioning adjustment component 2 and the flexible clamping component 3 to operate.

[0030] The positioning and adjustment assembly 2 includes a drive motor 201, a transmission gear 202, a rack and pinion slide rail 203, a slider 204, a positioning plate 205, and an adjusting screw 206. Two rack and pinion slide rails 203 are symmetrically fixedly connected to the top of the assembly platform 1, and are arranged along the length of the assembly platform 1. The slider 204 is slidably connected to the rack and pinion slide rails 203 via a groove. The top of the slider 204 is bolted to the positioning plate 205, and the adjusting screw 206 is threaded through the middle of the positioning plate 205. One end of the adjusting screw 206 is connected to the slider 204 via a thread. The other end of the adjusting screw 206 is equipped with a handwheel; rotating the handwheel rotates the adjusting screw 206, thereby achieving fine-tuning of the positioning plate 205. The top of the positioning plate 205 is provided with anti-slip textures 207, which are distributed in a grid pattern and have a depth of 0.5 mm. A drive motor 201 is embedded in one side of the assembly platform 1. A transmission gear 202 is fixedly connected to the top of the output shaft of the drive motor 201 via a key. The transmission gear 202 is meshed with the rack and pinion slide rail 203. When the drive motor 201 is started, the transmission gear 202 rotates and moves along the rack and pinion slide rail 203, thereby driving the slider 204 and the positioning plate 205 on its top to move linearly.

[0031] The flexible clamping assembly 3 includes a clamping cylinder 301, a clamping arm 302, a guide groove 303, an elastic pressure plate 304, buffer springs 305, and a clamping pad 306. Two clamping cylinders 301 are symmetrically fixedly connected to one side of the assembly platform 1. The output end of the clamping cylinder 301 is fixedly connected to the clamping arm 302 via a flange. A guide groove 303 is formed on the inner side of the clamping arm 302, and an elastic pressure plate 304 is slidably connected inside the guide groove 303. Four buffer springs 305 are bolted to one side of the elastic pressure plate 304. The buffer springs 305 are evenly distributed on one side of the elastic pressure plate 304, and the other end of each buffer spring 305 is bolted to the inner wall of the guide groove 303. On the other side of the elastic pressure plate 304, a clamping pad 306 is glued and fixed. The clamping pad 306 is made of polyurethane material, and its surface is provided with anti-slip protrusions 307. The anti-slip protrusions 307 have a diameter of 2mm and are evenly distributed on the surface of the clamping pad 306. When the clamping cylinder 301 is activated, the clamping arm 302 moves inward, and the elastic pressure plate 304 contacts the surface of the oil pan through the force of the buffer spring 305. The anti-slip protrusions 307 of the clamping pad 306 further enhance the clamping stability.

[0032] In the actual assembly process, the oil pan to be assembled is first placed on top of the assembly platform 1. The operator inputs instructions via the operation button 501 on the control panel 5, and the PLC controller 502 controls the drive motor 201 to start according to the instructions. The drive motor 201 is connected to the rack and pinion slide rail 203 through the transmission gear 202, driving the slider 204 to move along the rack and pinion slide rail 203, thereby adjusting the position of the positioning plate 205. The top of the positioning plate 205 is provided with anti-slip texture 207 to prevent the oil pan from shifting during assembly. When the position of the positioning plate 205 is close to the target position, the operator can make fine adjustments by rotating the handwheel of the adjusting screw 206 to make the positioning plate 205 fit tightly against the edge of the oil pan.

[0033] Subsequently, the PLC controller 502 controls the clamping cylinder 301 to start, which pushes the clamping arm 302 inward. An elastic pressure plate 304 is provided on the inner side of the clamping arm 302, and the elastic pressure plate 304 contacts the surface of the oil pan through the force of the buffer spring 305. Since the elastic pressure plate 304 can slide within the guide groove 303, it can automatically adjust its position according to the shape of the oil pan, ensuring a uniform distribution of clamping force. The clamping pad 306 is made of polyurethane material, and its surface is provided with anti-slip protrusions 307, which can prevent damage to the surface of the oil pan during clamping and improve clamping stability.

[0034] After assembly, the operator inputs a command via the operation button 501 on the control panel 5. The PLC controller 502 controls the clamping cylinder 301 to retract, and the clamping arm 302 to move outward, releasing the assembled oil pan. The operator then removes the oil pan from the assembly platform 1, completing the assembly process. Throughout the assembly process, the vibration damping pad 401 at the bottom of the assembly platform 1 effectively absorbs vibrations, reduces noise during equipment operation, and extends the equipment's service life.

[0035] In the above embodiments, the connection, position, and cooperation relationships between the various components are all achieved through specific structural designs. For example, the drive motor 201 is connected to the rack and pinion slide rail 203 via the meshing of the transmission gear 202, realizing the linear motion of the slider 204; the clamping cylinder 301 is connected to the clamping arm 302 via a flange, and the elastic pressure plate 304 on the inner side of the clamping arm 302 is connected to the guide groove 303 via a buffer spring 305, achieving a uniform distribution of clamping force. These designs enable this invention to adapt to oil pans of different sizes and ensure its stability and safety during assembly.

[0036] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0037] In the actual operation of the oil pan assembly fixture, the oil pan to be assembled is first placed on top of the assembly platform 1. The operator inputs the start command through the operation button 501 on the control panel 5. After receiving the command, the PLC controller 502 drives the drive motor 201 in the positioning adjustment assembly 2 to start working. The transmission gear 202 fixed to the top of the output shaft of the drive motor 201 meshes with the rack and pinion slide rail 203. When the transmission gear 202 rotates, it moves along the rack and pinion slide rail 203, thereby driving the slider 204 and its top positioning plate 205 to move linearly. During this process, the slider 204 ensures the smoothness of movement through the cooperation of the slide groove and the rack and pinion slide rail 203, avoiding positioning deviations caused by mechanical vibration.

[0038] When the positioning plate 205 is close to the target position, the operator can fine-tune the positioning plate 205 by rotating the handwheel of the adjusting screw 206. One end of the adjusting screw 206 is connected to the slider 204 via a thread, and the other end is equipped with a handwheel. Rotating the handwheel can precisely adjust the position of the positioning plate 205, making it fit tightly against the edge of the oil pan. The anti-slip texture 207 on the top of the positioning plate 205 is distributed in a grid pattern with a depth of 0.5mm, which can effectively prevent the oil pan from shifting during assembly, thereby ensuring positioning accuracy.

[0039] Subsequently, the PLC controller 502 controls the clamping cylinder 301 in the flexible clamping assembly 3 to start. The clamping cylinder 301 pushes the clamping arm 302 to move inward, and the elastic pressure plate 304 on the inner side of the clamping arm 302 contacts the surface of the oil pan through the force of the buffer spring 305. Since the elastic pressure plate 304 can slide in the guide groove 303, it can automatically adjust its position according to the shape of the oil pan to ensure uniform distribution of clamping force. In addition, the clamping pad 306, which is fixed to the other side of the elastic pressure plate 304 by adhesive, is made of polyurethane material and has anti-slip protrusions 307 with a diameter of 2mm on its surface. These anti-slip protrusions 307 can prevent damage to the surface of the oil pan during clamping and improve clamping stability.

[0040] After assembling the oil pan, the operator inputs a command again via the operation button 501 on the control panel 5. The PLC controller 502 controls the clamping cylinder 301 to retract, and the clamping arm 302 moves outward, releasing the assembled oil pan. The operator then removes the oil pan from the assembly platform 1, completing the assembly process. Throughout the assembly process, the vibration damping pads 401 at the bottom of the assembly platform 1 absorb vibrations through the elastic properties of the rubber material, reducing noise during equipment operation and extending the equipment's service life.

[0041] In the above steps, the connection and cooperation between the various components are achieved through specific structural designs. For example, the drive motor 201 is connected to the rack and pinion slide rail 203 via the meshing of the transmission gear 202, realizing the linear motion of the slider 204; the clamping cylinder 301 is connected to the clamping arm 302 via a flange, and the elastic pressure plate 304 on the inner side of the clamping arm 302 is connected to the guide groove 303 via a buffer spring 305, achieving a uniform distribution of clamping force. These designs enable this invention to adapt to oil pans of different sizes and ensure its stability and safety during assembly.

Electrical control components not mentioned in this technical solution are existing technologies and are not shown in the figures; therefore, they will not be described further here.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
