[0022] The technical solution of this utility model will be further described below with reference to specific embodiments:

[0023] like Figure 4 As shown, a combination tooling for machining small rocker arms includes a base plate 1, several positioning blocks 2, side blocks 3, an adjusting pressure plate, a leveling block 6, a clamping block 7, auxiliary support columns 8, two end pressure plates 9, and a middle pressure plate 10. The positioning blocks 2 and side blocks 3 are fixedly installed on the base plate 1. The positioning blocks 2 and side blocks 3 cooperate to clamp two symmetrically placed small rocker arms. The adjusting pressure plate presses tightly against the upper surface of the small rocker arm. The leveling block 6 is fixed on the base plate 1. The upper part of the leveling block 6 has a plane parallel to the side of the small rocker arm. The clamping block 7 is set above the adjusting pressure plate and presses tightly against the boss on the reverse side of the mounting surface of the small rocker arm. The auxiliary support columns 8 are divided into two groups and symmetrically arranged to support the bottom side of the small rocker arm. The two end pressure plates 9 are respectively located above the two groups of auxiliary support columns 8 to press the two ends of the small rocker arm. The middle pressure plate 10 presses the middle part of the small rocker arm.

[0024] There are two pairs of positioning blocks 2, symmetrically arranged at both ends of the horizontal axis on the base plate 1. Positioning blocks 2 have positioning pin holes, which connect to the positioning holes in the small rocker arm connecting rod via pins. There are also two pairs of side blocks 3, symmetrically arranged at both ends of the horizontal axis on the base plate 1. The side blocks 3 abut against the positioning points on the sides of the small rocker arms. The cooperation of positioning blocks 2 and side blocks 3 allows for the simultaneous clamping and alignment of two symmetrically placed small rocker arms.

[0025] The adjusting pressure plate consists of four first adjusting pressure plates 4 and two second adjusting pressure plates 5. The first adjusting pressure plates 4 are symmetrically arranged on both ends of the outer side of the two small rocker arms, and the two second adjusting pressure plates 5 are arranged on both sides of the small rocker arms.

[0026] The first adjusting pressure plate 4 includes a first pressure plate, a locking bolt, and a support screw. A slot is milled in the middle of the first pressure plate, through which the support screw passes. This slot design allows the first pressure plate to move back and forth when clamping the small rocker arm, facilitating operation. Adjusting the height of the first pressure plate on the support screw ensures effective clamping force. The pressure plate is locked with the locking bolt to secure the small rocker arm. The head of the first pressure plate is cylindrical, corresponding to the central hole in the connecting rod section of the small rocker arm.

[0027] Two small rocker arms share a set of second adjusting pressure plates 5, which include second pressure plates and middle bolts, the second pressure plates are provided with through holes, and the middle bolts pass through the through holes. After the first adjusting pressure plates 4 are locked, the two ends of the second pressure plates press the one end of the two small rocker arms respectively, so as to prevent the two small rocker arms from moving.

[0028] The contour blocks 6 are provided with six locking sink holes for being fixed on the bottom plate 1, and the upper part of the contour blocks 6 is provided with pin holes which are parallel to the plane of the side surface of the small rocker arms and correspond to the positioning holes of the side surface of the small rocker arms. The positioning of the side surface of the small rocker arms is realized by inserting the positioning pins into the pin holes and the positioning holes of the side surface of the small rocker arms respectively.

[0029] Each set of auxiliary support columns 8 has three, which are arranged at the two ends and the middle of the small rocker arms, and are used for supporting the bottom of the side edge of the small rocker arms. In normal state, the height is fixed, when the pressing block 7 presses the small rocker arms and the installation surface is not flat, the height of the adjusting screw of the auxiliary support column 8 is adjusted to be in effective contact with the small rocker arms. The auxiliary support column 8 is connected by two coaxial cylinders with different sizes.

[0030] The pressing block 7 is composed of a pressing screw and a pressure plate, and a set of the pressing block 7 is shared between the two small rocker arms. The small rocker arms are fixed by pressing the bosses on the opposite side of the installation surface of the small rocker arms.

[0031] A support rod is arranged between the two pairs of auxiliary support columns 8 below the two ends of the two small rocker arms, and a through hole is arranged in the middle of the two end pressure plates 9, and the support rod passes through the through hole. The end pressure plate 9 is connected with the support rod through the through hole. The two end pressure plates 9 are arranged in the middle of the two small rocker arms, and are used for pressing the two ends of the small rocker arms. The end pressure plate 9 and the small rocker arms are locked by the locking screw. The support rod is used for supporting the pressure plate and limiting the moving direction of the pressure plate.

[0032] The middle pressure plate 10 is provided with slots at the two ends, and is engaged with the position of the reinforcing rib of the middle part of the small rocker arms. The middle pressure plate 10 is locked by the locking screw to press the middle part of the small rocker arms.

[0033] The embodiment is only a further explanation of the invention, and is not a limitation of the invention. Those skilled in the art can make non-creative modifications to the embodiment according to the needs after reading the specification, but as long as it is within the scope of the claims of the invention, it is protected by the patent law.
