Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and in particular to a production fixture for automotive engine skirts. Background Technology

[0002] The engine skirt is an important component of the engine, located at the bottom and surrounding components such as the crankcase. During its production, operators place the skirt on a workbench and secure it firmly with clamping components, providing a foundation for subsequent inspection, installation, and other processes.

[0003] To achieve multi-directional inspection of the skirt frame, it is often necessary to rotate the clamping components. This is typically accomplished using a motor, a rotating block, and a connecting shaft. After the motor starts, it drives the connecting shaft to rotate, and the connecting shaft transmits torque to the rotating block. The connection structure between the rotating block and the clamping components causes the clamping components and the internally fixed skirt frame to rotate together, meeting the needs of skirt frame position adjustment in different inspection or processing scenarios.

[0004] However, in actual operation, one motor provides power to rotate the clamping component, and the rotational torque is transmitted through the clamping component to the skirt frame, and then to the other clamping component to achieve synchronous rotation. But because the torque is large and the transmission loss is uneven, the skirt frame is subjected to additional stress, which can easily affect the quality of the skirt frame.

[0005] Therefore, it is necessary to provide automotive engine skirt production fixtures to solve the above-mentioned technical problems. Utility Model Content

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A schematic diagram of a preferred embodiment of the automotive engine skirt production fixture provided by this utility model; Figure 2 for Figure 1 The diagram shows a partial sectional view. Figure 3 for Figure 2The enlarged schematic diagram of part A is shown. The automotive engine skirt production fixture includes: a worktable 1, with two telescopic components 2 on the top of the worktable 1; a rotating component 3 on the outside of each of the two telescopic components 2; a displacement component 4 on the outside of each of the rotating components 3; a clamping component 5 on the outside of each of the displacement components 4; and a synchronous rotation assembly 6 on the outside of the worktable 1. The synchronous rotation assembly 6 includes a rotating shaft 61, rotating gears 62, a rotary motor 63, transmission gears 64, a first synchronous pulley 65, a second synchronous pulley 66, and a synchronous belt 67. The rotating shaft 61 is connected to the worktable 1... The worktable 1 is rotatably connected, the rotating gear 62 is fixedly connected to the rotating shaft 61, the rotary motor 63 is fixedly connected to the worktable 1, the transmission gear 64 is fixedly connected to the rotary motor 63, the transmission gear 64 meshes with the rotating gear 62, the first synchronous pulley 65 is fixedly connected to the rotating shaft 61, the second synchronous pulley 66 is connected to the rotating component 3, and the synchronous belt 67 is drively connected to the first synchronous pulley 65 and the second synchronous pulley 66. An adjustment component 7 is provided on the outside of the worktable 1 for adjusting the tension of the synchronous belt 67.

[0029] The workbench 1 provides the mounting base for each component. The telescopic component 2 controls the height of the rotating component 3, the displacement component 4, and the clamping component 5 to accommodate different skirt heights. The displacement component 4, in conjunction with the clamping component 5, can accommodate skirts of different sizes. When the skirt on the clamping component 5 is flipped, the rotary motor 63 in the synchronous rotation assembly 6 starts the transmission gear 64 to rotate, thereby causing the meshing rotary gear 62 to rotate, which in turn drives the rotating shaft 61 to rotate. When the rotating shaft 61 rotates, the first synchronous pulley 65 rotates, and under the transmission of the synchronous belt 67, the second synchronous pulley 66 rotates. The second synchronous pulley 66 is connected to the rotating component 3, which drives the rotating component 3 to rotate, allowing the skirt on the clamping component 5 to be flipped. When the telescopic component 2 is height adjusted, the tension of the synchronous belt 67 can be adjusted through the control component 7, allowing normal transmission between the first synchronous pulley 65 and the second synchronous pulley 66.

[0030] The telescopic component 2 includes a sleeve 21, an extension column 22, and an electric push rod 23. The sleeve 21 is fixedly connected to the worktable 1, the extension column 22 is slidably connected to the sleeve 21, the electric push rod 23 is fixedly connected to the worktable 1, and the output end of the electric push rod 23 is fixedly connected to the extension column 22.

[0031] When the equipment is in operation and needs to be adjusted according to different skirt heights, the electric push rod 23 receives instructions from the control panel and pushes the extension column 22 to rise or fall in the sleeve 21 through the telescopic movement of its output end, thereby driving the rotating component 3, displacement component 4 and clamping component 5 connected to the extension column 22 to adjust the height together.

[0032] The rotating component 3 includes a limiting groove 31, a limiting block 32, a short shaft 33, and a turntable 34. The limiting groove 31 is opened on the outside of the extension column 22. The limiting block 32 is rotatably connected to the limiting groove 31. The short shaft 33 is rotatably connected to the extension column 22. The limiting block 32 is fixedly connected to the short shaft 33. The turntable 34 is fixedly connected to the short shaft 33. The second synchronous pulley 66 is fixedly connected to the short shaft 33.

[0033] When the first synchronous wheel 65 in the synchronous rotation assembly 6 rotates under the drive of the rotating shaft 61, and transmits power to the second synchronous wheel 66 through the synchronous belt 67, the second synchronous wheel 66 drives the short shaft 33 to rotate, which in turn drives the turntable 34 connected to it to rotate. Since the turntable 34 is connected to the displacement component 4 and the clamping component 5, the skirt on the clamping component 5 is finally flipped. The axial movement of the short shaft 33 during rotation can be prevented by the cooperation of the limiting groove 31 and the limiting block 32.

[0034] The displacement component 4 includes a hydraulic column 41, two sliding rods 42, and a mounting base 43. The hydraulic column 41 is fixedly connected to the turntable 34, the two sliding rods 42 are slidably connected to the hydraulic column 41, the mounting base 43 is fixedly connected to the output end of the hydraulic column 41, and the two sliding rods 42 are fixedly connected to the mounting base 43.

[0035] A hydraulic column 41 is fixed to the turntable 34, providing power for the displacement movement. Two sliding rods 42 are slidably connected to the base plate on which the hydraulic column 41 is mounted. The base plate is fixed to the turntable 34, and its length is greater than the diameter of the turntable 34. During operation, when it is necessary to adjust the position of the clamping component 5 to accommodate different sizes of skirts, the hydraulic column 41 starts to work. The extension and retraction of the output end of the hydraulic column 41 will drive the mounting base 43 fixed to it to move. Since the sliding rod 42 is fixed to the mounting base 43, and the sliding rod 42 can slide on the base plate on which the hydraulic column 41 is mounted, the mounting base 43 will move horizontally along the sliding rod 42, realizing the horizontal displacement of the clamping component 5 connected to the mounting base 43.

[0036] The clamping component 5 includes a bidirectional lead screw 51 and two clamping plates 52. The bidirectional lead screw 51 is rotatably connected to the mounting base 43, and the two clamping plates 52 are threadedly connected to the bidirectional lead screw 51.

[0037] When the bidirectional lead screw 51 rotates, the two clamping plates 52 move towards or away from each other along the axial direction of the bidirectional lead screw 51, thereby achieving clamping and releasing operations for skirts of different sizes. To make the movement of the clamping plates 52 smoother, a guide rail and a guide groove are provided between the clamping plates 52 and the mounting base 43. The guide rail is fixedly mounted on the mounting base 43, and the guide groove is located on the side of the clamping plate 52 that contacts the mounting base 43, cooperating with the guide rail. This prevents the clamping plates 52 from shaking during movement.

[0038] The control component 7 includes a cylinder 71 and a guide wheel 72. The cylinder 71 is fixedly connected to the worktable 1, the guide wheel 72 is fixedly connected to the cylinder 71, and the guide wheel 72 is drivenly connected to the synchronous belt 67.

[0039] When the telescopic component 2 adjusts the height of the rotating component 3, the displacement component 4, and the clamping component 5, the position of the entire mechanism changes accordingly, which may alter the tension of the synchronous belt 67. At this time, the cylinder 71 extends or retracts as needed, causing the guide wheel 72 to change position accordingly. Since the guide wheel 72 is connected to the synchronous belt 67, the change in the position of the guide wheel 72 applies different forces to the synchronous belt 67, thereby adjusting the tension of the synchronous belt 67 and ensuring stable and normal transmission between the first synchronous pulley 65 and the second synchronous pulley 66 via the synchronous belt 67.

[0040] A stabilizing component 8 is provided on the outside of the turntable 34. The stabilizing component 8 includes an annular groove 81 and an annular block 82. The annular groove 81 is opened on the outside of the turntable 34. The annular block 82 is rotatably connected to the annular groove 81 and is fixedly connected to the extension column 22.

[0041] The cooperation between the annular groove 81 and the annular block 82 can effectively limit the radial sway and axial movement of the turntable 34 during rotation, thereby improving the stability of the turntable 34 rotation.

[0042] The working principle of the automotive engine skirt production fixture provided by this utility model is as follows:

[0043] First, the operator issues a command via the control panel to start the equipment. At this point, the workbench 1 serves as the mounting base for all components. The telescopic component 2 operates according to the skirt height information input on the control panel, controlling the heights of the rotating component 3, the displacement component 4, and the clamping component 5 to accommodate skirts of different heights. Simultaneously, the displacement component 4 and the clamping component 5 cooperate to adjust their positions based on the skirt size data provided on the control panel, accommodating skirts of different sizes and completing the positioning and initial fixation of the skirt. Then, when it is necessary to flip the skirt already fixed on the clamping component 5, a flipping command is issued again via the control panel. Upon receiving the command, the rotary motor 63 in the synchronous rotation assembly 6 starts, driving the transmission gear 64 to rotate. The transmission gear 64 meshes with the rotating gear 62, thereby driving the rotating gear 62 to rotate. The rotation of the rotating gear 62 drives the connected rotating shaft 61 to rotate. The rotation of shaft 61 causes synchronous pulley 65 to rotate synchronously. Under the transmission of synchronous belt 67, synchronous pulley 66, connected to rotating component 3, also begins to rotate, thereby driving rotating component 3 to rotate. Ultimately, this achieves the flipping of the skirt on clamping component 5, meeting the needs for skirt position adjustment in different inspection or processing scenarios. Finally, during the height adjustment of telescopic component 2 to adapt to different skirt heights, the control panel automatically triggers the operation of regulating component 7. Regulating component 7 adjusts the tension of synchronous belt 67 in real time, ensuring normal transmission between synchronous pulley 65 and synchronous pulley 66, guaranteeing the stability and reliability of the entire equipment operation, and providing assurance for skirt inspection.

[0044] Compared with related technologies, the automobile engine skirt production fixture provided by this utility model has the following beneficial effects:

[0045] The worktable 1, telescopic component 2, rotating component 3, displacement component 4, clamping component 5, synchronous rotation component 6, and control component 7 work together to enable the clamping component 5 to rotate smoothly and synchronously. This effectively avoids the problem of excessively long torque transmission path caused by one-sided motor drive, resulting in large torque and uneven transmission loss. This ensures that the skirt frame does not bear additional stress during rotation, avoiding the adverse effects of uneven force on the quality of the skirt frame and ensuring the quality stability of the skirt frame during inspection and subsequent processing.
