DETAILED DESCRIPTION

[0028] The present invention provides an assembly structure of an oil drain bolt and an oil pipe bolt of an oil pan. In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the scope of protection of the present invention.

[0029] See also Figure 1-Figure 3 and Figure 8 The present invention provides an assembly structure of an oil drain bolt and an oil pipe bolt of an oil pan, comprising a frame (not shown in the figure), a positioning plate 1 arranged on the frame, a clamping mechanism 3, a side tightening mechanism 4, an upper tightening mechanism 5, and a supporting mechanism 2 arranged on the positioning plate 1; the supporting mechanism 2 is used to support the oil pan 10, and the clamping mechanism 3 is used to clamp the oil pan 10 on the positioning plate 1; please refer to Figure 4 The side tightening mechanism 4 includes a side displacement component 42 and a side tightening component 43. The side displacement component 42 is used to drive the side tightening component 43 to move toward the oil drain installation hole of the oil pan 10. The side tightening component 43 is used to assemble the oil drain bolt 20 into the oil drain installation hole; please refer to Figure 6 The upper tightening mechanism 5 includes a fixed plate 51, an upper moving and loading assembly 52 and an upper tightening assembly 53. The fixed plate 51 is fixedly connected to the frame. The upper moving and loading assembly 52 is arranged on the fixed plate 51, and the upper moving and loading assembly 52 is used to drive the upper tightening assembly 53 to move toward the oil pipe mounting hole of the oil pipe 30. The upper tightening assembly 53 is used to assemble the oil pipe bolt 40 into the oil pipe mounting hole.

[0030] In actual application, the oil pan 10 is first supported and positioned by the supporting mechanism 2 to determine the placement position of the oil pan 10; then the clamping mechanism 3 is used to apply a clamping force to the oil pan 10 to clamp and fix the oil pan 10. This clamping force is evenly distributed on the oil pan 10 to prevent the oil pan 10 from moving during the assembly of the oil drain bolt 20 and the oil pipe bolt 40; the side tightening assembly 43 and the upper tightening assembly 53 are in a standby state on the frame, and the worker or the manipulator places the oil drain bolt 20 to be assembled in the oil drain mounting hole and the oil pipe bolt 40 in the oil pipe mounting hole. When the oil pan 10 is correctly positioned and fixed, the side tightening assembly 43 is used to assemble the oil drain bolt 20 into the oil drain mounting hole, and the upper tightening assembly 53 is used to assemble the oil pipe bolt 40 into the oil pipe mounting hole under the transfer of the side transfer assembly 42 and the upper transfer assembly 52.

[0031] In the above structure, the design of the positioning plate 1 and the supporting mechanism 2 ensures the precise position of the oil pan 10 during the assembly process, and can provide a precise reference for the assembly of the drain bolt 20 and the oil pipe bolt 40, ensuring that the drain bolt 20 and the oil pipe bolt 40 can be accurately assembled into the drain mounting hole and the oil pipe mounting hole, improving the matching accuracy of the bolt and the mounting hole, and reducing the installation problems caused by position deviation. Moreover, the entire assembly structure is reasonably designed, and each component works together, making the bolt assembly operation streamlined and efficient. The operator only needs to place the oil pan 10 on the supporting mechanism 2, start the clamping mechanism 3, the side tightening mechanism 4 and the upper tightening mechanism 5 to complete the assembly of the drain bolt 20 and the oil pipe bolt 40. The operation is simple and convenient, the assembly process is simplified, and the assembly efficiency is greatly improved.

[0032] See also Figure 3 In some embodiments, the side shifting load component 42 is a first cylinder, the side tightening component 43 is a side torque gun, and the output end of the first cylinder is connected to the side torque gun through the side shifting load plate 41; the muzzle of the torque gun faces the oil drain installation hole of the oil pan 10. In the initial state, the first cylinder is in an unactivated state (the output end is in a contracted state), the side torque gun is in a standby state, and the worker can place the oil drain bolt 20 in the oil drain installation hole. Transfer process: the first cylinder receives a control signal to start, and its output end begins to extend, driving the side shifting load plate 41 and the side torque gun to move toward the direction of the oil drain installation hole (for illustration, it moves to the left). Through the precise stroke of the first cylinder and the stable movement of the side shifting load plate 41, the muzzle of the side torque gun can be accurately aligned with the oil drain installation hole of the oil pan 10. Tightening operation: When the muzzle of the side torque gun is aimed at the oil drain installation hole, the side torque gun is started, and according to the preset torque parameters, the side torque gun begins to rotate, gradually screwing the oil drain bolt 20 into the oil drain installation hole. During the tightening process, the side torque gun will continuously monitor the torque size, and when the set torque value is reached, the side torque gun stops rotating to ensure that the oil drain bolt 20 is accurately and appropriately tightened, completing the assembly of the oil drain bolt 20.

[0033] See also Figure 3 In some embodiments, the lower surface of the side shifting carrier plate 41 is provided with a side slider 411, and the upper surface of the frame is provided with a side slide rail 412 which is consistent with the extension direction of the output end of the first cylinder, and the side slider 411 is slidably arranged on the side slide rail 412. When the first cylinder is started and pushes the side shifting carrier plate 41 at its output end, the side slider 411 on the lower surface of the side shifting carrier plate 41 will slide along the side slide rail 412 on the upper surface of the frame, and the side slide rail 412 provides a clear movement path for the side slider 411, limiting the side shifting carrier plate 41 to move only on a straight line which is consistent with the extension direction of the output end of the first cylinder, so as to achieve a more stable, accurate and smooth linear movement of the side shifting carrier plate 41.

[0034] See also Figure 3 In some embodiments, two or more side buffer blocks 413 are further provided on the upper surface of the frame, and the plurality of side buffer blocks 413 are respectively located on both sides of the travel direction of the side shift carrier 41 (taking the figure as an example, the side buffer blocks 413 are located on the left and right sides of the side shift carrier 41). When the side shift carrier 41 moves rapidly along the side slide rail 412 driven by the first cylinder, a certain impact force may be generated due to the start, stop or speed change during the movement. At this time, the side buffer blocks 413 located on both sides of the travel direction of the side shift carrier 41 can contact the side shift carrier 41 when it approaches the stroke limit position or when the speed suddenly changes, and absorb part of the kinetic energy of the side shift carrier 41 through its own elastic deformation, thereby effectively reducing the impact of the impact force on the side shift carrier 41, the side torque gun and the entire equipment, and avoiding the occurrence of situations such as damage to components or affecting assembly accuracy due to severe impact. The main purpose of the above-mentioned setting is to provide buffering and limit protection during the movement of the side shift carrier 41.

[0035] See also Figure 7 In some embodiments, the positioning plate 1 is further provided with an oil drain bolt detection sensor 11, which is used to detect whether an oil drain bolt 20 is placed in the oil drain installation hole. It is of great significance to provide the oil drain bolt detection sensor 11 on the positioning plate 1. During the assembly process of the oil pan 10, accurately knowing whether there is an oil drain bolt 20 in the oil drain installation hole is the key to ensure the smooth progress of subsequent operations. If the side torque gun tightening operation is started without the oil drain bolt 20, it may cause the equipment to run idle, damage the gun head of the torque gun, or affect the efficiency and accuracy of the entire assembly process.

[0036] See also Figure 5In some embodiments, a gasket detection mechanism 6 is also provided on the frame, and the gasket detection mechanism 6 includes a mounting seat 61, a first detection cylinder 62 provided on the mounting seat 61, a detection plate 63 connected to the output end of the first detection cylinder 62, a second detection cylinder 64 provided on the detection plate 63, and a stroke sensor 65 connected to the output end of the second detection cylinder 64; the extension direction of the output end of the first detection cylinder 62 is perpendicular to the extension direction of the output end of the second detection cylinder 64; the output end of the second detection cylinder 64 extends in the direction of the oil drain installation hole; the stroke sensor 65 is used to measure the distance from the stroke sensor 65 to the oil drain installation hole. Initial state: When the device does not start the detection operation, each component is in the initial position, the output ends of the first detection cylinder 62 and the second detection cylinder 64 are both in the retracted state, the stroke sensor 65 is relatively far from the oil drain installation hole, and the entire gasket detection mechanism 6 is in a standby state. Action of the first detection cylinder 62: When the gasket detection program is started, the first detection cylinder 62 first receives the control signal and starts, and its output end extends, pushing the detection plate 63 connected to it to move along the extension direction of the output end of the first detection cylinder 62. The purpose of this action is to make a preliminary position adjustment of the detection plate 63 in a plane, so that the subsequent second detection cylinder 64 can better push the stroke sensor 65 to a suitable position for detection. Action of the second detection cylinder 64: After the first detection cylinder 62 pushes the detection plate 63 to a suitable position, the second detection cylinder 64 receives the control signal and starts, and its output end extends, pushing the stroke sensor 65 in the direction toward the oil drain installation hole. Since the output end of the second detection cylinder 64 extends in the direction of the oil drain installation hole, the stroke sensor 65 will gradually approach the oil drain installation hole under the push of the second detection cylinder 64. Distance measurement and detection analysis: As the stroke sensor 65 gradually approaches the oil drain installation hole, it begins to measure the distance from itself to the oil drain installation hole. The distance information obtained can be compared with a preset standard distance value (such as the theoretical distance value from the stroke sensor 65 to the drain installation hole after the appropriate gasket is installed). If the measured distance value is consistent with the standard distance value, it can be preliminarily determined that a suitable gasket is installed at the drain installation hole; if the distance value is significantly different from the standard distance value, it may indicate that the gasket is incorrectly installed or not installed, so that further corresponding measures can be taken to deal with it. The design of the gasket detection mechanism 6 is mainly to accurately detect whether a suitable gasket is installed at the drain installation hole. During the assembly process of the oil pan 10, the correct installation of the gasket is crucial to ensure the sealing performance of the drain bolt 20. If the gasket is not installed or installed improperly, it may cause the drain bolt 20 to be loosely sealed after tightening, thereby causing problems such as oil leakage. Through this precise gasket detection mechanism 6, gasket-related problems can be discovered in a timely manner, the assembly quality can be improved, and the normal use of the engine oil pan 10 can be guaranteed.

[0037] See also Figure 6 In some embodiments, the upper moving and carrying assembly 52 is a second cylinder, the upper tightening assembly 53 is an upper torque gun, and the output end of the second cylinder is connected to the upper torque gun through the upper moving and carrying plate 54; the muzzle of the torque gun faces the oil pipe installation hole of the oil pipe 30. Similarly, the extension or contraction of the output end of the second cylinder drives the upper torque gun to descend or ascend, so that the oil pipe bolt 40 is quickly assembled into the oil pipe installation hole.

[0038] See also Figure 6 In some embodiments, an upper slider 511 is disposed on the back of the upper moving carrier plate 54, and an upper slide rail 512 extending in the same direction as the output end of the second cylinder is disposed on the front of the fixed plate 51, and the upper slider 511 is slidably disposed on the upper slide rail 512. Similarly, by using the upper slider 511 and the upper slide rail 512, the upper moving carrier plate 54 can be smoothly raised or lowered.

[0039] See also Figure 6 In some embodiments, two or more upper buffer blocks 513 are further provided on the front of the fixed plate 51, and the plurality of upper buffer blocks 513 are respectively located on both sides of the moving direction of the upper moving carrier 54. Similarly, the main purpose of the above arrangement is to provide buffering and limiting protection during the movement of the upper moving carrier 54.

[0040] See also Figure 6 In some embodiments, a fuel pipe bolt detection sensor 514 is further provided on the fixing plate 51, and the fuel pipe bolt detection sensor 514 is used to detect whether a fuel pipe bolt 40 is placed in the fuel pipe installation hole. Similarly, the fuel pipe bolt detection sensor 514 controls the start and stop of the entire assembly process.

[0041] See also Figure 7 and Figure 8 In some embodiments, the support mechanism 2 includes two or more support seats 21 disposed on the upper surface of the positioning plate 1, wherein the upper surfaces of two or more of the support seats 21 are provided with positioning pins 211, and the positioning pins 211 are used to be inserted into the positioning holes 50 of the oil pan 10. In this embodiment, the upper surfaces of the two support seats 21 located on the diagonal line are provided with positioning pins 211, which can not only meet the requirements of accurate positioning of the oil pan 10, but also shorten the time consumption when the positioning holes 50 of the oil pan 10 and the positioning pins 211 are aligned, greatly simplifying the process of assembling the oil pan 10 and the bolts, and accelerating the assembly efficiency.

[0042] See also Figure 7In some embodiments, the upper surface of the positioning plate 1 is further provided with a plurality of foolproof blocks 22. The provision of the foolproof blocks 22 can provide clear direction guidance for the assembly of the oil pan 10 and the bolts, and by limiting the placement direction of the oil pan 10, the staff can quickly and accurately place the oil pan 10 in the correct position, avoiding assembly rework caused by wrong direction.

[0043] See also Figure 7 In some embodiments, a plurality of proximity sensors 12 are further provided on the upper surface of the positioning plate 1; the plurality of proximity sensors 12 are used to detect whether an oil pan 10 is placed on the positioning plate 1. When the proximity sensor 12 detects that there is no oil pan 10 on the positioning plate 1, other mechanisms will not be started, which can avoid meaningless actions of the assembly structure in the absence of the oil pan 10. Moreover, in the automated production process, the proximity sensor 12 can quickly feedback the placement of the oil pan 10 to the control system. When it is detected that the oil pan 10 is placed, the system can immediately start the assembly process without manual confirmation. Conversely, when the oil pan 10 is removed, the system can stop related operations in time.

[0044] See also Figure 1 and Figure 8 In some embodiments, the clamping mechanism 3 includes a clamping cylinder 31 with an output end facing upward, a hinged seat 32 disposed on the cylinder body of the clamping cylinder 31, and a pressure rod 33 connected to the output end of the clamping cylinder 31; the middle part of the pressure rod 33 is hinged to the hinged seat 32, and the free end of the pressure rod 33 is used to insert into the notch 60 on the upper surface of the oil pan 10. The clamping mechanism 3 of this embodiment is set to three. Initial state: When the clamping operation is not started, the output end of the clamping cylinder 31 is in a retracted state. At this time, the middle part of the pressure rod 33 rotates around the hinged seat 32, so that the free end of the pressure rod 33 is away from the notch 60, and the entire clamping mechanism 3 is in a standby state. Start the clamping operation: When the oil pan 10 needs to be clamped, the clamping cylinder 31 receives a control signal and starts, and the output end of the clamping cylinder 31 extends. The process of rotation and clamping of the pressure rod 33: Since the middle part of the pressure rod 33 is hinged to the hinge seat 32, as the output end of the clamping cylinder 31 rises, the pressure rod 33 rotates with the hinge point as the fulcrum. During the rotation of the pressure rod 33, the free end of the pressure rod 33 gradually moves downward, and finally the free end of the pressure rod 33 is pressed into the notch 60 of the oil pan 10. Then, as the piston of the clamping cylinder 31 continues to extend, the pressure rod 33 will be further pressed down to achieve the clamping operation of the oil pan 10. In this way, the stability of the oil pan 10 during the assembly process can be ensured, and the displacement or shaking of the oil pan 10 during the subsequent bolt tightening operation can be prevented.

[0045] In summary, the present invention provides a support mechanism 2 for supporting and positioning the oil pan 10; a clamping mechanism 3 for clamping and fixing the oil pan 10 on the positioning plate 1; a side tightening mechanism 4 for assembling the drain bolt 20 into the drain mounting hole; an upper tightening mechanism 5 for assembling the drain bolt 20 into the oil pipe mounting hole; the above structure ensures the precise position of the oil pan 10 during the assembly process, can provide a precise reference for the assembly of the drain bolt 20 and the oil pipe bolt 40, ensure that the drain bolt 20 and the oil pipe bolt 40 can be accurately assembled into the corresponding mounting holes, reduce installation problems caused by position deviation, and is simple and convenient to operate, simplifies the assembly process, and greatly improves the assembly efficiency.
