[0002] The current cylinder head valve stem seal press-fitting device is a semi-automatic station, requiring manual visual inspection to check if the valve stem seal top spring is missing. The seal is placed on the fixture and then installed onto the press head. The operator visually inspects the seal top for springs, which can lead to fatigue and poor work quality over extended periods, affecting inspection accuracy. The valve stem seal press head has an internal vacuum adsorption mechanism; the vacuum adsorption is used to check if the valve stem seal is properly seated on the press head. The valve stem seal uses a steel structure and a cylinder-driven press-fitting mechanism; even slight misalignment can lead to misalignment and damage to the valve stem seal. Therefore, it is necessary to check if the valve stem seal is properly pressed in. Summary of the Invention

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This utility model proposes an engine cylinder head valve oil seal press-fitting device, such as... Figures 1 to 4 As shown, a preferred embodiment of the engine cylinder head valve oil seal press-fitting device of this utility model includes: a column 1, a press-fitting mechanism 2, and a drive mechanism. The drive mechanism is disposed on the top of the column 1. The press-fitting mechanism 2 includes a triangular mounting bracket 3, a press head X-axis moving mechanism 4, a press head Y-axis moving mechanism 5, and a press head 6. The triangular mounting bracket 3 is connected to the drive mechanism. The press head X-axis moving mechanism 4 is disposed on the triangular bracket. The press head Y-axis moving mechanism 5 is connected to the press head X-axis moving mechanism 4. The press head 6 is disposed on the press head Y-axis moving mechanism 5.

[0018] This embodiment realizes the automatic position adjustment and pitch change function of the pressure head 6 through the X-axis moving mechanism 4 and the Y-axis moving mechanism 5 of the pressure head, realizing a design that does not require hardware replacement, greatly reducing replacement time and replacement cost.

[0019] A pressure head spring 7 is provided on the top of the pressure head 6, and this spring has an automatic correction function. In this embodiment, by providing a pressure head spring 7 on the top of the pressure head 6, it has a corrective effect on small positional deviations and is less likely to damage the pressure head 6.

[0020] The inner wall of the pressure head 6 is provided with a through-beam fiber optic sensor 9 for detecting the valve stem seal 16 and the spring on top of the valve stem seal 16. In this embodiment, the through-beam fiber optic sensor 9 on the inner wall of the pressure head 6 can detect both the presence of the valve stem seal 16 and the presence of the oil seal spring 8 on top of the valve stem seal 16, effectively improving detection efficiency and accuracy.

[0021] The bottom of the pressure head 6 is provided with a push pin 10 that is interference-fitted with the valve oil seal 16. In use, the push pin 10 is interference-fitted with the valve oil seal 16, making it less likely to fall off, thus realizing oil seal material removal. This saves resources and costs compared to the vacuum adsorption technology in the prior art.

[0022] Furthermore, in this embodiment, the engine cylinder head valve oil seal pressing device also includes a flipping mechanism 11 disposed at the lower end of the column 1 and a tray connected to the flipping mechanism 11, the tray being used to place the cylinder head 12. A magnetic switch 13 is provided on the column 1 for controlling the flipping mechanism 11 to flip. The magnetic switch 13 ensures that the cylinder head 12 is flipped into place.

[0023] Furthermore, in this embodiment, the column 1 is provided with a press-fit sensor 14 for detecting whether the valve stem seal 16 is press-fitted in place.

[0024] Furthermore, in this embodiment, the driving mechanism is a servo motor 15. This embodiment uses the servo motor 15 to control the pressing depth, and a pressing-in position sensor 14 is installed on the column 1 to detect whether the oil seal is pressed in place.

[0025] The working process of this engine cylinder head valve oil seal press-fitting device is as follows: First through such Figure 5The vibrating material mechanism 17 shown delivers the valve stem seals 16 in an orderly manner to the feeding mechanism 18, which then delivers them to the valve stem seal pressing device for the engine cylinder head of this utility model. The servo motor 15 then drives the pressing head 6 to move downwards, clamping the valve stem seals 16 from the valve stem seal tray. During this process, the ejector pin 10 of the pressing head 6 is interference-fitted with the valve stem seal 16 to achieve material removal. Next, the servo motor 15 drives the pressing head 6 to rise, and the through-beam fiber optic sensor 9 detects the ejector pin of the valve stem seal 16. Whether or not there is an oil seal spring 8, at the same time, the X-axis moving mechanism 4 and the Y-axis moving mechanism 5 of the pressure head drive the pressure head 6 to change pitch, so as to align with the tilting cylinder; then, the tilting cylinder rotates to the intake side, the servo motor 15 drives the pressure head 6 to press down, press the oil seal into the cylinder head 12, when the pressing position sensor 14 detects that the pressure head 6 is pressed in place, the servo motor 15 drives the pressure head 6 to rise, the pressing on the intake side is completed, the tilting cylinder flips to the exhaust side, and the above steps are repeated to realize the pressing of the valve oil seal 16.

[0026] In summary, the beneficial effects of this utility model's engine cylinder head valve oil seal press-fitting device are: This utility model, through the above technical solution, includes: a column, a pressing mechanism, and a driving mechanism. The driving mechanism is disposed on the top of the column. The pressing mechanism includes a triangular mounting bracket, a pressing head X-axis moving mechanism, a pressing head Y-axis moving mechanism, and a pressing head. The triangular mounting bracket is connected to the driving mechanism. The pressing head X-axis moving mechanism is disposed on the triangular bracket. The pressing head Y-axis moving mechanism is connected to the pressing head X-axis moving mechanism. The pressing head is disposed on the pressing head Y-axis moving mechanism. A pressing head spring is disposed on the top of the pressing head. A through-beam fiber optic sensor for detecting the valve stem seal and the sealing spring on the top of the valve stem seal is disposed on the inner wall of the pressing head. A pin with an interference fit to the valve stem seal is disposed on the bottom of the pressing head. This realizes automatic monitoring of whether there is a spring on the top of the sealing seal and the pressing status, improving the pressing qualification rate and reducing labor costs.

[0027] To achieve the above objectives, this utility model also proposes an engine cylinder head valve oil seal press-fitting device, such as... Figure 5 As shown, the engine cylinder head valve oil seal press-fitting equipment includes the engine cylinder head valve oil seal press-fitting device as described above, which will not be repeated here.

[0028] As one implementation, the engine cylinder head valve oil seal pressing equipment further includes a vibrating mechanism 16 and a feeding mechanism 17. After the vibrating mechanism 16 orderly feeds the valve oil seal to the feeding mechanism 17, the feeding mechanism 17 transports the valve oil seal to the engine cylinder head valve oil seal pressing device and presses it into the cylinder head 12.
