[0035] Example 1

[0036] like Figure 1-5 As shown, the utility model proposes an auxiliary assembly device for cylinder head assembly production, including a mounting frame 1, a lifting assembly 2, a limiting assembly 3, a support rod 4 and an internal threaded sleeve 52;

[0037] There are two lifting assemblies 2, which are installed on both sides of the interior of the mounting frame 1. Each lifting assembly 2 is provided with a support assembly 5 on the side thereof for synchronously moving up and down with the lifting assembly 2 when in use. An internally threaded sleeve 52 is installed on the support assembly 5 and moves laterally inside the support assembly 5 when in use. The middle portion of the internally threaded sleeve 52 has a threaded hole for mating with the support rod 4.

[0038] The support rod 4 is inserted into the inner side of the internal threaded sleeve 52 and is threadedly connected to the cylinder head for connecting the internal threaded sleeve 52 and the cylinder head into one piece when in use;

[0039] The limiting assembly 3 is installed at the end of the internal threaded sleeve 52 for connecting with the supporting assembly 5 and limiting the position of the internal threaded sleeve 52 when in use.

[0040] In this embodiment, the lifting components 2 are manipulated separately so that the two lifting components 2 respectively drive the support components 5 to move to the bolt holes of the cylinder head, and the support rod 4 is threadedly installed on the inner side of the internal threaded sleeve 52, and the lateral position of the internal threaded sleeve 52 is adjusted so that the support rod 4 is coaxial with the threaded hole of the cylinder head. One end of the support rod 4 passes through the threaded hole of the internal threaded sleeve 52 and is installed on the inner side of the threaded hole of the cylinder head. The limit component 3 is connected to the support component 5 to fix the position of the support rod 4 on the lifting component 2. The lifting component 2 drives the cylinder head to move to the required height, and then pushes the mounting frame 1 to move the cylinder head above the cylinder body. Then, the two lifting components 2 synchronously drive the cylinder head downward so that the cylinder head moves horizontally downward, and by adjusting the position of the mounting frame 1, the cylinder head is accurately assembled on the cylinder body, making the assembly of the cylinder head more convenient.

[0041] Example 2

[0042] like Figure 3-4 As shown, the utility model proposes an auxiliary assembly device for cylinder head assembly production. Compared with the first embodiment, the support assembly 5 in this embodiment includes a rib plate 51 and a mounting plate 53;

[0043] The mounting plate 53 is mounted on the side of the lifting assembly 2. The mounting method is not limited to direct connection. In order to quickly disassemble and assemble the lifting assembly 2 and the support assembly 5, a bolt connection method can be selected for connection.

[0044] The ribs 51 are slidably connected to the mounting plate 53 and are two in number. The ends of the ribs 51 are respectively connected to the upper and lower end surfaces of the internally threaded sleeve 52 for maintaining the straightness of the internally threaded sleeve 52 in use.

[0045] In an optional embodiment, a slider is provided at one end of the rib plate 51, and a slide groove is provided on the side of the mounting plate 53; when the rib plate 51 and the mounting plate 53 are in the state of being installed in cooperation, the slider of the rib plate 51 is accommodated in the inner side of the slide groove of the mounting plate 53, and is used for the mounting plate 53 to have a limiting effect on the rib plate 51 when in use, so that the rib plate 51 pulls the internal threaded sleeve 52 when in use, generates a force on the internal threaded sleeve 52, and prevents the internal threaded sleeve 52 from bending downward.

[0046] In an optional embodiment, a waist-shaped hole is provided on the end face of the mounting plate 53, and the internal threaded sleeve 52 passes through the waist-shaped hole and is connected to the limiting assembly 3 for limiting the moving direction of the internal threaded sleeve 52 in use, and the position of the internal threaded sleeve 52 is fixed by the limiting assembly 3, and the rib plate 51 moves synchronously with the internal threaded sleeve 52 and slides on the inner side of the slide groove of the mounting plate 53.

[0047] Example 3

[0048] like Figure 1-2 As shown, the utility model proposes an auxiliary assembly device for cylinder head assembly production. Compared with the first embodiment, in this embodiment, the lifting component 2 includes a motor 21, a lead screw 22 and a connecting block 23;

[0049] The motor 21 is mounted on the upper end surface of the mounting frame 1;

[0050] The lead screw 22 is rotatably mounted on the mounting frame 1, and its top end passes through the mounting frame 1 and is transmission-connected to the motor 21, and its transmission connection is not limited to a direct connection;

[0051] The connecting block 23 is sleeved on the outside of the screw 22, and has a threaded hole in the middle thereof that cooperates with the screw 22 for driving the screw 22 to move 13 up and down when in use. It should be noted that the projection shape of the connecting block 23 is rectangular, and the side surface of the connecting block 23 is arranged in a fit state with the inner side of the mounting frame 1. Therefore, when the screw 22 drives the connecting block 23 to move up and down when in use, resistance is generated between the connecting block 23 and the mounting frame 1, avoiding the problem that the screw 22 rotates and drives the connecting block 23 to rotate and cannot move up.

[0052] Example 4

[0053] like Figure 2 As shown, the utility model proposes an auxiliary assembly device for cylinder head assembly production. Compared with the first embodiment, in this embodiment, the limiting component 3 includes a connecting plate 31 and a bolt 32;

[0054] The connecting plate 31 is mounted on the end of the internally threaded sleeve 52 and has a through hole in the middle thereof that is connected to the threaded hole of the internally threaded sleeve 52 so that the support rod 4 can pass through the through hole and be inserted into the inner side of the internally threaded sleeve 52 when in use.

[0055] The bolt 32 is threadedly connected to the end of the connecting plate 31, and one end passes through the end of the connecting plate 31 and contacts the mounting plate 53. It is used to pull the internal threaded sleeve 52 toward the back of the mounting plate 53 when in use, so that the internal threaded sleeve 52 drives the rib plate 51 to generate pressure on the mounting plate 53, fix the internal threaded sleeve 52 on the mounting plate 53, and adjust the position of the support rod 4 to avoid lateral movement of the internal threaded sleeve 52 during the up and down movement of the cylinder head.

[0056] Example 5

[0057] like Figure 5 As shown, the utility model proposes an auxiliary assembly device for cylinder head assembly production. Compared with the first embodiment, in this embodiment, the support rod 4 includes a mounting rod 41, a connecting rod 42 and a connecting head 43;

[0058] The mounting rod 41 is inserted into the inner side of the support assembly 5 and the outer side of the mounting rod 41 has threads that match the threaded holes of the internal threaded sleeve 52. The outer side of the mounting rod 41 is fully threaded to prevent the connecting rod 42 from being unable to be disassembled if it is bent.

[0059] The connecting rod 42 is provided at one end of the mounting rod 41 and is threadedly connected to the cylinder head. In order to accommodate threaded holes of different sizes on the cylinder head, threads are provided on the outer sides of the mounting rod 41 and the connecting rod 42 respectively, so that mounting rods 41 of different sizes can be interchangeably installed during use without having to replace the support assembly 5.

[0060] The connecting head 43 is arranged at the other end of the mounting rod 41 and is used to connect the mounting rod 41 and the connecting rod 42 to the internal threaded sleeve 52 and the cylinder head respectively when in use, and the cylinder head can be moved up and down by driving the support assembly 5 upward by the lifting assembly 2. The shape and groove of the connecting head 43 are set in conjunction with commonly used tools.

[0061] In summary, when the present invention is in use, the mounting bracket 1 is pushed to locate the cylinder head on the inner side of the mounting bracket 1, and the motor 21 drives the lead screw 22 to rotate, so that the lead screw 22 drives the connecting block 23 to move downward along the inner side wall of the mounting bracket 1. During the downward movement, the connecting block 23 drives the support assembly 5 to move synchronously, so that the support assembly 5 moves to the side of the cylinder head, and the end of the mounting rod 41 is installed on the inner side of the internal threaded sleeve 52 through the connecting head 43. The connecting rod 42 is located on the inner side of the internal threaded sleeve 52, and the internal threaded sleeve 52 is moved laterally to align the support rod 4 with the threaded hole of the cylinder head, and the connecting head 43 is continued to be screwed to completely install the mounting rod 41 in the cylinder head. The connecting rod 42 is installed in the threaded hole of the internal threaded sleeve 52, and the bolt 32 is passed through the threaded hole of the connecting plate 31 to connect with the mounting plate 53, and the internal threaded sleeve 52 is pulled toward the mounting plate 53 through the connecting plate 31. The internal threaded sleeve 52 drives the rib plate 51 to squeeze the mounting plate 53, so that the position of the internal threaded sleeve 52 is fixed, and the supporting assembly 5 is driven upward by the lifting assembly 2, and the mounting frame 1 is pushed at the same time, and the mounting frame 1 is moved toward the cylinder body, so that the mounting frame 1 can position the cylinder head above the cylinder body through its own moving wheels, and the cylinder head can be accurately assembled on the cylinder body by fine-tuning the position of the mounting frame 1.

[0062] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
