Description

Technical Field

[0001] This utility model belongs to the field of automotive repair tools, specifically relating to an auxiliary tool for installing valve lock clips. Background Technology

[0002] In the intricate structure of an automotive engine, the valve lock clip (also known as the valve plate) is crucial. It acts like a safety lock, ensuring the valve stem is securely held within the valve spring seat. The valve's internal design features a small groove that, in conjunction with the valve spring's force, allows for smooth valve opening and closing. However, in actual maintenance, the valve spring preload is typically 20-30 kg, requiring manual pressing. Traditional installation methods often require two operators: one to hold the valve spring down, and the other to install the valve lock clip. This method has several drawbacks: first, the lack of specialized tools increases the risk of errors, potentially damaging or losing parts; second, the need for two operators can lead to coordination problems and increase the difficulty of installation; and third, the long pressing time increases labor intensity. Furthermore, due to the valve lock clip's unique installation position, even slight mishaps during installation can cause the valve spring to tilt or the clip to dislodge, affecting the valve's normal operation. Especially without specialized tools, installation efficiency and quality are difficult to guarantee.

[0003] To address the aforementioned issues, there is an urgent market need for an auxiliary tool that allows for efficient and accurate installation of valve lock clips by a single operator. This tool should possess the following characteristics: first, it should securely fix the valve spring, preventing it from tilting or popping out during installation; second, it should allow for single-person installation and removal of the valve lock clip, improving installation efficiency; and third, it should have a reasonable and simple structural design, making it easy to manufacture. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary tool for valve lock clamp installation, which can use the drill bit of a drilling machine to press down the valve spring, thereby enabling single-person valve lock clamp installation work.

[0005] The technical solution of this utility model is as follows:

[0006] This utility model discloses an auxiliary tool for installing valve lock clips on automobile engines, comprising a drill bit fixing part and a support part. The drill bit fixing part includes a connecting rod and a connecting plate, with the connecting rod fixed at the center of the connecting plate. The support part is cylindrical, with its upper part fixedly connected to the bottom of the connecting plate and its lower part having no bottom surface. A lock clip installation port is provided on the side of the support part.

[0007] The drill bit fixing part is used to fix the present invention to the drill bit of the drilling machine, and the support part is used to transmit the downward force of the drill bit to the engine valve spring.

[0008] Furthermore, the connecting rod is a bolt, and a nut is welded to the lower part of the connecting rod. The lower part of the nut is welded to the center of the metal connecting plate. Both the connecting rod and the connecting plate are made of steel and are connected by welding.

[0009] Furthermore, two locking clip mounting holes are provided on the side of the support. The two locking clip mounting holes are symmetrical about the central axis of the connecting plate. After the lower part of the support abuts against the engine valve spring, the operator can install the two valve locking clips, which are divided into two pieces, onto the engine valve from two symmetrical directions through the two openings.

[0010] Furthermore, the support part is made of HPB300 grade or higher steel. To ensure that the installation tool will not deform due to compression when pressing the engine valve spring, which could lead to improper installation of the valve lock clip and valve leakage, or even worse, tool breakage and injury to the operator, it is necessary to use high-strength steel, preferably HPB300 grade or higher steel.

[0011] Furthermore, the connecting disc is circular, and the support portion is cylindrical; this is the first embodiment.

[0012] Furthermore, the connecting plate is square, and the support part is square cylindrical, which is the second embodiment.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. This utility model provides an auxiliary tool for installing automotive engine valve lock clips, which can firmly fix valve springs, prevent springs from tilting or jumping out during installation, and ensure the accuracy and stability of the installation work.

[0015] 2. This utility model enables a single person to install and remove the valve lock clip, improving installation efficiency;

[0016] 3. The structure of this utility model is reasonable and simple, and easy to manufacture. Attached Figure Description

[0023] It should be noted that relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0024] This utility model discloses an auxiliary tool for installing valve lock clamps for automobile engines, comprising a drill bit fixing part 1 and a support part 2. The drill bit fixing part 1 includes a connecting rod 11 and a connecting plate 12, with the connecting rod 11 fixed at the center of the connecting plate 12. The support part 2 is cylindrical, with its upper part fixedly connected to the bottom of the connecting plate 12 and its lower part having no bottom surface. A lock clamp installation port 21 is provided on the side of the support part 2.

[0025] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0026] like Figures 3-4 As shown, when installing or removing the valve lock clip 32 of an automobile engine, it is often necessary for one person to press down on the valve spring 31 to keep it in a compressed state, relieve the pressure of the valve spring 31 on the valve lock clip 32, and then install or remove the valve lock clip 32. Otherwise, the valve lock clip 32 may not be installed properly, causing the engine valve 3 to leak air. Even worse, when removing or installing the valve lock clip 32 under force, the valve lock clip 32 may pop out, causing injury to the staff.

[0027] like Figures 1-4The first embodiment of this utility model is shown. When using this utility model to compress the valve spring 31, firstly, screw the connecting rod 11 of this utility model into the screw hole of the drill press 4 and fix it. Then, control the drill bit 41 to align with the engine valve 3 below, and slowly lower the drill bit 41. After the bottom of the support part 2 of this utility model contacts the valve spring 31 and ensures that the force position is accurate and the force is even, slowly control the drill bit 41 to apply downward pressure. After compressing the valve spring 31 by about 5cm through the drill bit 41, ensure that the locking clamp mounting part 33 is fully exposed. The locking clamp mounting part 33 is provided with a slot 34 at the bottom. A complete valve lock clamp 32 is divided into two identical locking pieces. The two locking pieces are installed on both sides of the locking clamp mounting part 33 through the two symmetrical locking clamp mounting holes 21. Press the two locking pieces together until they are tightly locked in the slot 34 and do not loosen. Finally, slowly lift the drill bit 41 until the upper part of the valve spring 31 and the lower part of the valve lock clip 32 are fully in contact and the force is evenly distributed. Then, raise the drill bit 41 and the valve lock clip 32 is installed.

[0028] like Figure 5 The second embodiment of this utility model is shown. This utility model can be made into a square tube shape. Although this makes the manufacturing more difficult, it can appropriately increase the thickness of the edge 5 of the square tube and increase the compressive strength of the support part 2, which can effectively reduce the risk of this utility model breaking under pressure.

[0029] The embodiments described above merely illustrate specific implementation methods of this application, and while the descriptions are detailed and specific, they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the technical solution of this application, and these modifications and improvements all fall within the scope of protection of this application.
