DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The valve cover press-fit clamping mechanism provides two technical solutions:

[0024] like Figure 1 and 2 The first embodiment is shown: it includes a base 1 and four clamping assemblies 2, the four corners of the top of the base 1 are fixedly connected with a slide bar 3, and the surface of the slide bar 3 is slidably connected with a workbench 4, a plurality of cushion blocks 7 are fixedly connected at equal distances in the annular direction of the bottom of the workbench 4, and the length of the cushion blocks 7 is greater than the length of the entire adjustment assembly 5 structure, and a multi-size clamping mechanism is arranged on the workbench 4, and the multi-size clamping mechanism includes:

[0025] The adjusting assembly 5 is arranged below the workbench 4 and is used to adjust the positions of the four clamping assemblies 2. The adjusting assembly 5 includes four slide grooves 51 opened along the annular direction of the top of the workbench 4. The inner surfaces of the four slide grooves 51 are slidably connected with sliders 52. The four clamping assemblies 2 are respectively installed on the tops of the corresponding sliders 52. The bottom of the workbench 4 is rotatably connected with a rotating ring, and the inner surface of the rotating ring is provided with an inner ring gear 54. Four intermediate gears 56 are rotatably connected with equal distances in the annular direction of the bottom of the workbench 4. The inner ring gear 54 meshes with the intermediate gear 56 for transmission. The bottoms of the four sliders 52 are fixedly connected with racks 55. The four racks 55 are respectively meshed with the intermediate gears 56 at four corresponding positions for transmission. The top of the workbench 4 is fixedly connected with a driving motor 57, and the output end of the driving motor 57 passes through the bottom of the workbench 4. The output end of the driving motor 57 is fixedly connected with a driving gear 58. The outer surface of the rotating ring is provided with an outer ring gear 53, and the outer ring gear 53 meshes with the driving gear 58 for transmission.

[0026] like Figure 1 and 3 The second embodiment is shown, and the main difference from the first embodiment is that a multi-size profiling cavity assembly 6 is arranged on the top of the workbench 4 and is used to place valves of different sizes. The multi-size profiling cavity assembly 6 includes a profiling cavity body 61, and the profiling cavity body 61 is provided with multiple sizes. A plurality of limiting rings 62 of decreasing sizes are fixedly connected at equal distances on the top of the workbench 4. The gaps between the plurality of limiting rings 62 form an insertion cavity 63, and the sizes of the plurality of insertion cavities 63 are respectively adapted to the limiting rings 62 of multiple sizes. A plurality of limiting rings 62 are provided with truncation grooves 64 corresponding to the position of the slide groove 51 at equal distances in the annular direction on the top.

[0027] When the position of the clamping assembly 2 needs to be adjusted, the driving motor 57 is started to fold the driving gear 58 to rotate, the driving gear 58 rotates and transmits it to the outer ring gear 53, thereby causing the inner ring gear 54 to rotate and transmit it to the middle gear 56, the middle gear 56 rotates and causes the driving motor 57 to move, and then the four clamping assemblies 2 are driven to move closer to or away from the middle at the same time through the slider 52, so as to adapt to valves of different sizes. In addition, after the position adjustment of the clamping assembly 2 is completed, a profiling cavity body 61 of suitable size is selected, and the limiting ring 62 is inserted into the insertion cavity 63 of the corresponding size, and the positioning block 65 is aligned with the position of the truncation groove 64 during the insertion.
