[0002] The engine is the most technologically intensive key component in the automotive field. In the process of assembling automobile engines, the automobile engine assembly line is particularly important due to the diversity of the assembled parts and the cumbersomeness of the process. The automobile engine assembly line is an assembly line process for sequential assembly of engines. Each station is an assembly line production. Therefore, the control of each link must have high reliability and a certain sensitivity to ensure the continuity and stability of production. Leak tests in automobile engine assembly lines include leak tests on cylinder blocks, engine assemblies, or valve oil seals.

The existing solution is to make multiple spring mechanisms on the surface of the workpiece to achieve the purpose of making the workpiece surface parallel to the plugging head, thereby meeting the plugging requirements, but this method requires a sufficiently large space.

[0022] The present invention is further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0023] Example 1

[0024] See also Figure 1 and 2As shown, this embodiment provides a floating plugging device. The floating plugging device comprises: a floating plugging assembly 1, a cylinder assembly 2 and a mounting seat assembly 3; the floating plugging assembly 1 is connected to the cylinder assembly 2; and the cylinder assembly 2 is mounted on the mounting seat assembly 3.

[0025] In this embodiment, the floating plugging assembly 1 includes: a centering block 4, a clamping head 5 and a plugging head 6; one end of the clamping head 5 is connected to the centering block 4 through a mounting plate 7, and the other end is fixed with the plugging head 6; wherein the plugging head 6 is fixed to the clamping head 5 by a bolt 12; one end of the centering block 4 is provided with a conical surface 11, and the mounting plate 7 is provided with a mounting hole 13, and the centering block 4 is connected to the clamping head 5 through the mounting hole 13; the conical surface 11 fits the surface of the mounting hole 13. Specifically, one end of the centering block 4 adopts a conical surface design, passes through the mounting plate 7 and is connected to one end of the clamping head 5, and is fixedly connected by a bolt 12; the other end of the clamping head 5 is connected to the plugging head 6 by a bolt 12, and the movement of the clamping head 5 drives the plugging head 6 to move in a directional direction, so that the plugging head 6 is parallel to the surface of the workpiece to meet the plugging requirements. The conical surface 11 of the centering block 4 is stuck in the mounting hole 13 of the mounting plate 4. The surface of the mounting hole 13 is also conical. In the initial state, the conical surface 11 of the centering block 4 and the surface of the mounting hole 13 are in contact with each other. At this time, the direction and position of the plugging head 6 are fixed and unique. When the plugging starts, the plugging head 6 contacts the surface of the workpiece. The surface of some workpieces is irregular. If the plugging head 6 directly contacts the surface of such workpieces, air leakage will occur, resulting in inaccurate testing. However, the conical surface 11 of the centering block 4 and the surface of the mounting hole 13 of the floating plugging device of this embodiment will gradually deviate and produce a gap as the cylinder moves and the clamping head 5 moves inward, so that the clamping head 5 can float within the aperture of the mounting hole 13, thereby compensating for the angle between the plugging head 6 and the surface of the workpiece, thereby meeting the plugging requirements.

[0026] In this embodiment, one end of the pressing head 5 is sleeved with a spring 8, and one end of the pressing head 5 is connected to the centering block 4 through the spring 8, wherein the centering block 4 is connected to the pressing head 5 through a bolt 12. Specifically, Figure 4 As shown, the clamping head 5 is composed of two cylinders with different diameters. The end with the spring 8 is a cylinder with a smaller diameter, which is convenient for setting the spring 8 on the cylinder; the other end is a cylinder with a larger diameter, which is convenient for fixing the plugging head 6. The end of the clamping head 5 with the spring 8 is fixedly connected to the centering block 4 by bolts; the column diameter of the end with the spring 8 is smaller than the aperture of the mounting hole 13. When the cylinder is actuated, the spring 8 is compressed, and the clamping head 5 will pass through the mounting hole 13 of the mounting plate 4 and float within the aperture range of the mounting hole 13, adjusting the deviation angle between the plugging head 6 and the workpiece surface to meet the plugging requirements.

[0027] In this embodiment, the mounting plate 7 is fixed on the mounting plate frame 9, and the mounting plate frame 9 is connected to the cylinder assembly 2 through the fixing plate 10. Specifically, the mounting plate 7 is fixed to the mounting plate frame 9 by bolts, the mounting plate frame 9 is fixed to the fixing plate, and the fixing plate 10 is connected to the cylinder assembly 2 through the fixing plate frame; when the cylinder moves, the floating plugging assembly 1 is driven to move to meet the plugging requirements. In order to ensure the working stability of the floating plugging device of this embodiment, adjustment pads and pads are designed on the mounting seat assembly to adapt to different leak test workplaces to ensure the accuracy of the leak test results and not be affected by off-site factors.

[0028] This embodiment provides a floating plugging device. The floating plugging device is designed to fit the centering block in the floating plugging assembly with the conical surface of the mounting hole in the mounting plate. The centering block is connected through the mounting plate via a spring and a clamping head. The cylinder is actuated to make the plugging head contact the surface of the workpiece. The clamping head floats in the mounting hole through spring compression to achieve angle compensation, so that the plugging head is parallel to the surface of the workpiece, reducing the possibility of air leakage, reducing the utilization of space, and improving the accuracy of the leak test.

[0029] The working principle of the utility model is: connect the floating plugging device of the utility model to ventilation, adjust the centering block 4 in the floating plugging assembly 1 so that the conical surface 11 fits with the surface of the mounting hole 13 in the mounting plate 7, and thus adjust the position of the plugging head 6. The cylinder is actuated, the floating plugging assembly 1 moves forward, and the plugging head 6 contacts the surface of the workpiece. At this time, the clamping head 5 moves inward, and the spring 8 is compressed and drives the clamping head 5 to pass through the mounting hole 13, so that a gap is generated between the conical surface 11 of the centering block 4 and the surface of the mounting hole 13. The clamping head 5 of the floating plugging device of the utility model has a rod diameter that is smaller than the diameter of the mounting hole 13 at one end of the clamping head 5 with the spring 8. The clamping head 5 can float within the diameter of the mounting hole 13 as the cylinder moves. The deviation angle between the plugging head 6 and the surface of the workpiece is adjusted by the floating of the clamping head 5, so that the plugging head 6 is parallel to the surface of the workpiece, thereby meeting the sealing requirements of the plugging.

Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
