Description

Technical Field

[0001] The present application relates to the technical field of engine assembly, and in particular to an engine valve lock clamp assembly tooling plate. Background Art

[0002] At present, the engine cylinder head valve lock clamp is assembled on the assembly line. Due to the variety of models and varieties, the number of cylinders of the engine is different, and there are single-cylinder and multi-cylinder (that is, the cylinders are divided into single-row and double-row). Cylinders with different numbers of rows require different valve lock clamp assembly plates to press down the valve spring to install the valve lock clamp. When pressing and installing multiple models and varieties of cylinder head valve lock clamps on the same equipment, multiple valve lock clamp assembly plates need to be replaced, and the number is large. Due to the engine replacement, the productivity is low. The present application provides a structure and method for cylinder head valve lock clamps that meet the needs of multiple models and varieties, solves the problem of different models and varieties needing to replace different cylinder head valve lock clamps for press-fitting, and improves productivity. Summary of the invention

[0003] In order to overcome the existing deficiencies, an embodiment of the present application provides an engine valve lock clip assembly tooling plate, which can adapt to the downward pressure of valve springs distributed in different rows and has higher adaptability to the installation of different engine valve lock clips.

[0004] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0007] The plurality of valve spring clamping mechanisms are all located in the installation cavity and are slidably fixed with the corresponding sliding cavity A and the sliding cavity B.

[0008] Furthermore, screw holes for connecting with an external equipment frame are opened at the four corners and the middle of the valve lock clamp assembly plate.

[0009] Furthermore, the valve spring clamping mechanism includes a pressure rod whose two ends are respectively slidably connected to the two opposite sliding cavities A, and fasteners slidably connected to the sliding cavity A and the sliding cavity B are provided at both ends of the pressure rod.

[0011] Furthermore, the fastener includes a locking bolt that can pass through the sliding cavity A, the sliding cavity B and the through hole, and a locking nut is tightened at the end of the locking bolt.

[0012] Furthermore, at least four valve spring clamping mechanisms are provided.

[0013] The advantages of the embodiments of the present application are:

[0014] The installation cavity, sliding cavity A and sliding cavity B are designed on the valve lock clamp assembly plate to cooperate with the valve spring clamping mechanism, which is beneficial for using a corresponding number of valve spring clamping mechanisms to press down the corresponding valve springs according to the number of valve rows, thereby exposing the valve lock clamp groove to install the valve lock clamp. This design improves the applicability of the engine valve lock clamp assembly tooling plate of the present application and improves the assembly efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solution in the embodiment of the present application is to solve the problems referred to in the above background technology, and the overall idea is as follows:

[0023] Embodiment 1:

[0024] like Figure 1-Figure 6The present invention discloses an engine valve lock clamp assembly tooling plate, comprising a valve lock clamp assembly plate 1 and a plurality of valve spring pressing mechanisms 2.

[0025] The valve lock clamp assembly plate 1 has an installation cavity 11 in the middle, and sliding cavities A12 communicating with the installation cavity 11 are transversely opened on both sides of the valve lock clamp assembly plate 1, and sliding cavities B13 communicating with the corresponding sliding cavities A12 are longitudinally opened on both sides of the valve lock clamp assembly plate 1;

[0026] A plurality of valve spring pressing mechanisms 2 are all located in the installation cavity 11 and are slidably fixed with the corresponding sliding cavities A12 and B13.

[0027] In this embodiment, the installation cavity 11, the sliding cavity A12 and the sliding cavity B13 are designed on the valve lock clamp assembly plate 1 to cooperate with the valve spring clamping mechanism 2, so as to facilitate the use of a corresponding number of valve spring clamping mechanisms 2 to press down the corresponding valve springs (not shown) according to the number of valve rows, thereby exposing the valve lock clamp groove to install the valve lock clamp. Such a design improves the applicability of the engine valve lock clamp assembly tooling plate of the present application and improves the assembly efficiency.

[0028] like Figure 1-Figure 2 As shown, the four corners and the middle of the valve lock clamp assembly plate 1 are all provided with screw holes 14 connected to the external equipment frame. The screw holes 14 can be used to install the valve lock clamp assembly plate 1 at the bottom of the equipment frame, so that the valve lock clamp assembly plate 1 can be driven by the external driving structure to press the valve spring downward.

[0029] like Figure 1 , Figure 3 and Figure 4 As shown, the valve spring pressing mechanism 2 includes a pressure rod 21 whose two ends are respectively slidably connected to two opposite sliding cavities A12, and fasteners 22 are provided at both ends of the pressure rod 21 for sliding connection to the sliding cavity A12 and the sliding cavity B13. Specifically, the position of the valve spring pressing mechanism 2 can be adjusted by utilizing the sliding relationship between the pressure rod 21 and the sliding cavity A12, so that the valve spring can be accurately pressed during the downward pressing process, and the design of the fastener 22 can increase the position stability of the pressure rod 21 after the position is adjusted.

[0030] Both ends of the pressure rod 21 are provided with through holes 211 adapted to the fastener 22. The design of the through holes 211 can facilitate the fastener 22 to penetrate and cooperate with the pressure rod 21.

[0031] The fastener 22 includes a locking bolt 221 that can pass through the sliding cavity A12, the sliding cavity B13 and the through hole 211, and a locking nut 222 is tightened at the end of the locking bolt 221. Specifically, when the pressure rod 21 moves to a suitable position, the locking bolt 221 is first passed through the sliding cavity A12, the sliding cavity B13 and the through hole 211, and then the locking nut 222 is screwed to the end of the locking bolt 221.

[0032] like Figure 1 It is shown that at least four valve spring clamping mechanisms 2 are provided. During operation, the valve spring clamping mechanism 2 can not only flexibly adjust the pressing position according to the position of the valve spring, but also select the number of valve spring clamping mechanisms 2 required to be used according to the number of rows of the valve spring, thereby improving the applicability of the present application.

[0033] When using this application:

[0034] According to the position and number of rows of valve springs, first slide the corresponding number of pressure rods 21 to the appropriate position, then pass the locking bolt 221 through the sliding cavity A12, the sliding cavity B13 and the through hole 211, and then screw the locking nut 222 on the end of the locking bolt 221. The external frame is connected to the cylinder, and the valve lock clamp assembly plate 1 is driven to move up and down by the up and down movement of the cylinder. The valve lock clamp assembly plate 1 moves downward so that the pressure rod 21 compresses the valve spring. When it is compressed to a certain extent, the position where the valve lock clamp is installed on the valve stem head of the cylinder head (i.e., the valve lock clamp groove) exposes the valve spring. After the valve lock clamps are installed on the valve stem head one by one by hand, the cylinder moves upward, the valve spring slowly moves upward, and the valve lock clamp is installed between the valve stem and the valve spring seat to complete the assembly of the valve lock clamp.

[0035] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present application, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present application.
