Description

Technical Field

[0001] The present application relates to the field of engine component installation, and particularly to a portable handheld valve lock clip installation device. Background Art

[0002] With the rapid development of the global automotive industry and the increasingly strict environmental protection regulations, small-displacement small engines have received extensive attention in the market due to their high efficiency, low fuel consumption, and low emission characteristics. Such engines usually adopt a modular design, including key components such as cylinder heads, valve lock clips, intake and exhaust valves, etc., and their assembly quality and efficiency directly affect the performance and stability of the engine. During the R & D stage of small-displacement small engines, the installation of valve lock clips is a key step, which directly affects the performance and reliability of the engine. Since this stage is mainly for the verification of new designs or improved designs, manual installation is usually adopted.

[0003] Regarding the above related technologies, the inventor believes that there are the following defects: Due to the limited installation position of the valve lock clip and the small size of the valve lock clip parts, the installation efficiency is low and the labor intensity is high, so there is room for improvement. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present application provides a portable handheld valve lock clip installation device to solve the above problems.

[0005] A portable handheld valve lock clip installation device includes a bracket, a top cover, a first-level rocker group, a second-level rocker group, a third-level rocker group, a push rod, and a drive group for pushing the bracket. The first-level rocker group includes two intersecting first-level rockers, and the middle parts of the two first-level rockers are rotatably connected to the bracket through a pin shaft. An activity slot is provided on the top cover for the end of the first-level rocker to be inserted and slide. The second-level rocker group includes two second-level rockers, and the third-level rocker group includes two third-level rockers. Both ends of each first-level rocker are respectively hinged to the second-level rocker and the third-level rocker. A guide hole for the push rod to pass through is provided in the middle of the bracket. One end of the push rod is hinged to the two second-level rockers through a pin shaft. A receiving groove for placing the valve lock clip is provided at one end of the third-level rocker. A support spring for resetting the push rod is sleeved on the push rod. The drive group is installed between the top cover and the bracket, and a pressing ring for pressing the valve spring seat is connected to the bracket.

[0006] By adopting the above technical solution, the connection and layout between components make the overall structure compact, facilitating hand-held operation. The driving group pushes the bracket, causing the pressing ring on the bracket to squeeze the valve spring seat. At the same time, the first-level rocker is pulled by the top cover, so that the ends of the third-level rocker approach and converge with each other. At this time, two valve retainers are placed in the receiving groove, and the second-level rocker pushes the ejector rod, and the ejector rod pushes the valve retainer into the designated position, thus easily realizing the installation of the valve retainer. The operation is simple and fast, and compared with the traditional manual installation, the installation efficiency can be significantly improved.

[0007] Optionally, a relief groove is formed on the inner wall of the receiving groove, and an elastic member for clamping the valve retainer is installed in the relief groove.

[0008] By adopting the above technical solution, the elastic member can ensure that the valve retainer is stably clamped in the receiving groove and is not easily detached; the design of the elastic member enables the device to adapt to valve retainers of different specifications, improving the versatility.

[0009] Optionally, the elastic member includes an elastic block and a limiting spring. The elastic block slides in the relief groove, one end of the limiting spring is connected to the elastic block, and the other end is connected to the bottom wall of the relief groove.

[0010] By adopting the above technical solution, the elastic block and the limiting spring work together to provide a more reliable clamping force for the valve retainer; the limiting spring can absorb the impact force during the installation process, protecting the valve retainer from damage. After the valve retainer is completely pushed out, the elastic block rebounds to prevent the valve retainer from being misaligned by being pulled back.

[0011] Optionally, the elastic block is made of fluororubber material.

[0012] By adopting the above technical solution, the fluororubber material has excellent wear resistance, which can extend the service life of the elastic block; the friction coefficient between the fluororubber material and the valve retainer is small, which helps to reduce the wear of the valve retainer.

[0013] Optionally, the driving group includes two pneumatic push rods installed on the top cover, and the end of the pneumatic push rod away from the top cover is connected to the bracket.

[0014] By adopting the above technical solution, the pneumatic push rod provides stable and strong power output to ensure the smooth progress of the installation process. The pneumatic push rod can be precisely controlled by adjusting the air pressure to meet different installation requirements.

[0015] Optionally, the pneumatic push rod is detachably connected to the top cover by bolts.

[0016] By adopting the above technical solution, the detachable connection makes the pneumatic push rod easy to replace or repair when a failure occurs, and the user can choose pneumatic push rods of different specifications for replacement according to actual needs.

[0017] Optionally, an auxiliary angle push rod is connected between each of the second-level rockers and the adjacent third-level rockers. One end of the auxiliary angle push rod is hinged to the middle of the second-level rocker, and a sliding block is rotatably connected to the other end. The sliding block is slidably connected to the third-level rocker.

[0018] By adopting the above technical solution, the auxiliary angle push rod ensures stable transmission between the second-level rocker and the third-level rocker, improves the installation accuracy. Through the sliding connection between the sliding block and the third-level rocker, the movement track of the rocker group is optimized, making the installation process smoother.

[0019] Optionally, the first-level rocker, the second-level rocker, the third-level rocker, the auxiliary angle push rod and the top cover are all made of stainless steel.

[0020] By adopting the above technical solution, stainless steel has excellent corrosion resistance and can resist various harsh environments. Stainless steel has high strength and hardness and can withstand large installation pressure and impact force. The components made of stainless steel have a long service life, reducing the maintenance cost.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. The connection and layout between components make the overall structure compact and convenient for hand-held operation. The driving group pushes the bracket, so that the pressing ring on the bracket presses the valve spring seat.

At this time, two valve retainers are placed in the receiving groove, and the second-level rocker pushes the ejector rod, and the ejector rod pushes the valve retainer into the designated position, thus easily realizing the installation of the valve retainer. The operation is simple and fast, and compared with the traditional manual installation, the installation efficiency can be significantly improved.

[0023] 2. The elastic block and the limit spring work together to provide a more reliable clamping force for the valve retainer; the limit spring can absorb the impact force during the installation process and protect the valve retainer from damage. After the valve retainer is completely ejected, the elastic block rebounds to prevent the valve retainer from being brought back and misaligned.

[0024] 3. Stainless steel has excellent corrosion resistance and can resist various harsh environments. Stainless steel has high strength and hardness and can withstand large installation pressure and impact force. The components made of stainless steel have a long service life, reducing the maintenance cost. BRIEF DESCRIPTION OF THE DRAWINGS
