Description

Technical Field

[0001] This utility model relates to a mechanical removal device, and more particularly to a removal device for the filter screen assembly of an oil control valve head. Background Technology

[0002] The oil control valve is the actuator of the engine's variable valve timing system. It regulates air volume by adjusting the advance and retardation of the valve opening angle to reduce fuel consumption and increase power. Therefore, it requires extremely high dimensional precision in the fitting of its components. During engine operation, the oil control valve's oil passage is connected to the engine's internal oil passages. Impurities generated during prolonged engine operation, as well as impurities inherent in the engine oil itself, can enter the oil control valve through this connection, causing it to stick. In severe cases, this can lead to the oil control valve completely jammed, resulting in an accident. Therefore, an oil filter assembly is installed at the oil inlet of the oil control valve head to reduce the amount of impurities entering the valve and affecting its performance.

[0003] During the production process, oil filter components may be damaged due to errors or other external factors, necessitating replacement. Oil filter components are typically snap-fitted to the oil control valve head, making them difficult to remove once installed. Traditionally, removal involves manual, forceful removal using tools. This method is labor-intensive, inefficient, and can easily scratch the valve body, rendering the oil control valve unusable. Furthermore, it poses a safety hazard as employees are at risk of hand injuries during the process.

[0004] Among them, such as Figure 1 and Figure 2 As shown, the main structure of the oil control valve mainly includes a main valve body a, a lug b extending to the side from the middle of the main valve body a, and a filter assembly c snapped into the head of the main valve body a. Utility Model Content

[0005] To address the aforementioned issues, this utility model aims to provide a device for removing the filter assembly of the oil control valve head. It features a novel structure, ease of use, high removal efficiency, and will not scratch the valve body during removal, ensuring safety and reliability.

[0006] The present invention relates to a device for removing the filter assembly of an oil control valve head, comprising a workbench, a fixed base, a first control valve, and a second control valve connected to the workbench. The oil control valve is fixedly mounted on the fixed base. A sliding cylinder is connected to the workbench behind the fixed base. The sliding cylinder is connected to the first control valve via an air pipe for reversing control. A sliding block is connected to the top of the sliding cylinder, and the sliding block is connected to the cylinder rod of the sliding cylinder. A clamping cylinder is connected to the top of the sliding block. Clamping blocks are connected to the left and right ends of the front side of the clamping cylinder, and blades are provided inside the clamping blocks. The clamping cylinder is connected to the second control valve via an air pipe for reversing control.

[0007] Preferably, the fixing seat has a mounting hole in the middle along the front-rear direction, and a positioning snap block is connected to the front side of the fixing seat. A backstop groove is formed between the positioning snap block and the fixing seat. After the front part of the oil control valve passes through the mounting hole, its lug rotates and snaps into the backstop groove for positioning.

[0008] Preferably, the first control valve is provided with a first reversing control handle, and the second control valve is provided with a second reversing control handle.

[0009] This utility model has a novel structure, is easy to use, has high dismantling efficiency, and will not scratch the valve body during dismantling, making it safe and reliable. Attached Figure Description

Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings.

[0017] like Figures 3 to 5 As shown, this utility model provides a device for removing the filter assembly of the oil control valve head, including a workbench 1. A fixed base 2, a first control valve 3, and a second control valve 4 are connected to the workbench 1. The oil control valve is fixed by the fixed base 2. A sliding cylinder 5 is connected to the workbench 1 on the rear side of the fixed base 2. The sliding cylinder 5 is connected to the first control valve 3 through an air pipe for reversing control. A sliding block 6 is connected to the top of the sliding cylinder 5. The sliding block 6 is connected to the cylinder rod of the sliding cylinder 5. A clamping cylinder 7 is connected to the top of the sliding block 6. Clamping blocks 8 are connected to the left and right ends of the front side of the clamping cylinder 7, respectively. A blade 9 is provided on the inner side of the clamping block 8. The clamping cylinder 7 is connected to the second control valve 4 through an air pipe for reversing control.

[0018] In the above scheme, the mounting hole is provided in the middle of the fixed seat 2 along the front-back direction, and the front side of the fixed seat 2 is connected to the positioning snap block 21. A backstop groove is formed between the positioning snap block 21 and the fixed seat 2. After the front part of the oil control valve passes through the mounting hole, its lug b rotates and snaps into the backstop groove for positioning.

[0019] Specifically, the first control valve 3 is provided with a first reversing control handle 31, and the second control valve 4 is provided with a second reversing control handle 41.

[0020] The working principle of this utility model is as follows:

[0021] The oil control valve head is inserted into the mounting hole of the fixing seat 2. The oil control valve is rotated, causing its lug b to rotate and engage in the anti-reverse groove for positioning. The first control valve 3 controls the sliding cylinder 5 to move forward to the outside of the filter assembly at the rear of the oil control valve. The second control valve 4 controls the clamping cylinder 7 to clamp inward, causing the blade 9 to embed into the filter assembly c at the head of the oil control valve. The clamping force of the clamping cylinder 7 causes the blade 9 to squeeze and cut into the filter assembly c, causing both sides of the filter assembly c to break. Since the bottom of the filter assembly c is not broken, it moves backward synchronously with the sliding cylinder 5, thus removing the filter assembly c. Then, the clamping cylinder 7 resets, and the oil control valve is removed, achieving quick and safe removal of the oil control valve filter assembly c.

[0022] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
