[0039] The specific embodiment can adjust the position of adjusting plate one 105 and adjusting plate two 204, so as to adjust the pressing position of the piston along the direction perpendicular to the feeding direction, and can adjust the end position of the movement of feeding seat 102 and the position of pressing cylinder 201 in the feeding direction, so as to adjust the pressing position of the piston along the direction parallel to the feeding direction, so that the pressing position of the piston matches the position of the engine cylinder, and the use flexibility of the pressing device is improved.

[0040] Adjusting plate one 105 and adjusting plate two 204 can be respectively driven by servo motors to realize accurate adjustment of the position, but the cost is higher by using two servo motors, and the same technical effect can be achieved by reducing the manufacturing cost, such as Figure 1 and Figure 2 As shown, in the specific embodiment, adjusting cylinder one 104 is connected with adjusting plate one 105, adjusting cylinder one 104 is arranged on mounting plate one 107, along the extending direction of adjusting cylinder one 104, the front end of adjusting plate one 105 can abut against feeding limiting assembly 108, feeding limiting assembly 108 is arranged on mounting plate one 107, the limiting position of feeding limiting assembly 108 can be adjusted, adjusting cylinder two 203 is connected with adjusting plate two 204, adjusting cylinder two 203 is arranged on mounting plate two 202, adjusting plate two 204 can abut against pressing limiting assembly 205, pressing limiting assembly 205 is arranged on mounting plate two 202, the limiting position of pressing limiting assembly 205 can be adjusted.

[0042] In this specific embodiment, the limiting rod 1081 is connected to the adjusting plate 1082 by a thread. The threaded connection allows for manual adjustment of the limiting position, thereby expanding the limiting range of the device and further broadening its applicability.

[0043] like Figure 2 As shown, in this specific embodiment, the adjusting plate 105 and the mounting plate 107, the adjusting plate 204 and the mounting plate 202 are all connected by slide rails. Along the extension direction of the adjusting cylinder 104, the rear of the mounting plate 107 and the mounting plate 202 are provided with hydraulic buffers 111. The two hydraulic buffers 111 can respectively abut against the rear ends of the adjusting plate 105 and the adjusting plate 204. The hydraulic buffers 111 and 103 can limit the final position of the cylinder retraction to avoid derailment. At the same time, the hydraulic buffers have hydraulic damping inside to avoid hard collisions.

[0044] like Figure 2As shown, in order to further reduce the cost, in the specific embodiment, the feeding driving member 106 adopts a feeding cylinder, and the feeding driving member 106 is arranged on the adjusting plate one 105. In order to adjust the feeding end position of the feeding cylinder, a limiting seat is arranged on the front end of the adjusting plate one 105 along the extending direction of the feeding cylinder. A hydraulic buffer two 103 is connected to the limiting seat through screw connection. The hydraulic buffer two 103 can abut against a trigger plate on the mounting plate one 107. The trigger plate is located in the front part of the feeding seat 102. The hydraulic buffer two 103 with the adjustable position through screw connection can adjust the end position of the feeding seat 102 in the cylinder stroke range, and further change the end position of the movement of the feeding seat 102 to match the position of the engine cylinder. Further, in order to adjust the position of the press-fitting cylinder 201, a mounting seat 206 is arranged on the cylinder body of the press-fitting cylinder 201. An installation hole is arranged on the mounting seat 206. A bolt is arranged in the installation hole. The installation hole is a straight slot hole. The length direction of the installation hole is perpendicular to the extending direction of the adjusting cylinder two 203. The mounting seat 206 is connected with the mounting plate two 202 through the installation hole.

[0045] The adjusting cylinder one 104, the adjusting cylinder two 203, the feeding driving member 106 and the adjusting motor 1083 of the device are electrically connected with the controller.

[0046] In order to improve the press-fitting precision and ensure the press-fitting quality, in the specific embodiment, the press-fitting shaft 112101 sequentially includes a press-fitting part, a limiting part and a transmission part arranged coaxially from top to bottom. The press-fitting part is a conical structure with the tip upward. The diameter of the limiting part is larger than that of the press-fitting part. The transmission part is a cylindrical structure.

[0047] In order to ensure the smooth return of the press-fitting shaft 112101 after the press-fitting, in the specific embodiment, a ring-shaped limiting groove is arranged on the outer circumferential surface of the lower end of the transmission part. A press-fitting seat is arranged on the top of the piston rod of the press-fitting cylinder 201. A containing cavity is arranged in the press-fitting seat.

In work, after the feeding seat 102 is moved to the position, the lower end of the press-fitting shaft 112101 enters the containing cavity of the press-fitting seat through the opening. When the press-fitting cylinder 201 extends, the top surface of the press-fitting seat abuts against the upper top surface of the limiting groove, and drives the press-fitting shaft 112101 to move upward until the press-fitting is completed. When the press-fitting cylinder 201 is retracted, the press-fitting shaft 112101 is pulled down to the set position. The reaction movement of the feeding seat 102 drives the press-fitting shaft 112101 to move out of the press-fitting seat from the opening.

[0048] The adjustment process of the piston feeding and press-fitting assembly is as follows:

[0049] First, input the engine cylinder body model, the controller obtains the position coordinates of the engine cylinder body, rotates the two adjusting motors 1083 to rotate the corresponding limit rods 1081 to the limit position, adjusts the cylinder one 104 and the cylinder two 203 to extend, until the jacks 110 and the top plate 501 abut against the corresponding limit plates; manually adjust the extension position of the hydraulic buffer two 103 on the limit seat, and further adjust the end position of the feeding of the feeding seat 102, so that the press-fitting shaft 112101 is coaxial with the cylinder body at the end position, and adjust the mounting position of the mounting seat 206 on the mounting plate two 202, so that the piston rod of the press-fitting cylinder 201 is coaxial with the press-fitting shaft 112101.

When the conveyor stop 7 receives a release signal, the stop block falls to release the clamp until the accompanying clamp moves to the rear of the front conveyor stop 7 and is sensed by the first sensor there. The stop block of the front conveyor stop 7 rises to prevent the accompanying clamp from moving further and waits for pressing at this point until the front conveyor stop 7 receives a release signal, at which point its stop block will fall. In this specific embodiment, the conveyor stop 7 is prior art and can be purchased on the market. Its structure will not be described in detail here.

The upper limit member 302 is set on the worktable and has a Z-shaped structure. A limit bolt 301 is vertically installed on the upper part of the upper limit member 302, and the limit bolt 301 can abut against the upper surface of the accompanying fixture. In this specific embodiment, four upper limit members 302 are provided and distributed at the four corners of the accompanying fixture.
