[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the scope of implementation of the present invention is not limited thereto.

[0015] It should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0016] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0017] like Figure 1 and Figure 2 As shown, a connecting rod joint adjustment hole processing fixture of this embodiment includes a base 1, a first vertical plate 2 and a second vertical plate 3 are arranged above the base 1, the first vertical plate 2 is fixedly connected to the base 1 and arranged vertically, the second vertical plate 3 is provided with a driving device 4 for driving the second vertical plate 3 to move, and a limiting device 5 is arranged at the end of the first vertical plate 2. Two cushion blocks 6 are arranged above the base 1, one end of the cushion block 6 is located between the first vertical plate 2 and the second vertical plate 3, and the other end is slidably connected to the second vertical plate 3. The limiting device 5 is arranged at one end of the first vertical plate 2 or at both ends. The limiting device 5 is arranged at both ends to realize a set of processing clamps to process the left and right connecting rod joints.

[0018] During operation, the connecting rod joint is placed between the first vertical plate 2 and the second vertical plate 3, and above the two pads 6, with the side plate facing the second vertical plate 3. The main body of the connecting rod joint is tilted to form an angle with the first vertical plate 2, and the opening of the threaded hole of the main body of the connecting rod joint contacts the first vertical plate 2 and the limit device 5 to achieve the positioning of the connecting rod joint; the driving device 4 drives the second vertical plate 3 to move toward the first vertical plate 2. During the movement, the second vertical plate 3 squeezes the axial hole portion of the connecting rod joint, and clamps the axial hole portion between the first vertical plate 2 and the second vertical plate 3 to achieve the fixation of the connecting rod joint, thereby achieving the positioning and fixation of the connecting rod joint, which is convenient for the tool to process the adjustment hole of the flank.

[0019] The two pads 6 are parallel and perpendicular to the first vertical plate 2 or the second vertical plate 3. The two pads 6 can respectively support the main body and the axial hole of the connecting rod joint, so that the adjustment hole below the side wing is suspended in the air, or a processing space for the hole is formed below the adjustment hole of the connecting rod side wing, so that two coaxial adjustment holes can be processed at one time, improving the processing efficiency and ensuring the processing accuracy; at the same time, the other end of the pad 6 can be used as a sliding rail for the sliding of the second vertical plate 3 to facilitate the sliding of the second vertical plate 3.

[0020] A limiting column 7 is arranged above the base 1 and is located on the inner side of the second vertical plate 3. The limiting column 7 limits the maximum displacement of the second vertical plate 3 to prevent the second vertical plate 3 from exerting excessive pressure on the outer wall of the shaft hole of the connecting rod joint.

[0021] The limiting device 5 is a limiting block, the angle between the inner side surface of the limiting block and the inner side surface of the first vertical plate 2 is not greater than 90°, or the limiting block is L-shaped. After the connecting rod joint is placed inside the device of the utility model, the threaded opening of the connecting rod joint body is clamped and fixed by the limiting block, and the positioning of the connecting rod joint can be achieved at the same time.

[0022] The driving device 4 is an electric screw or a cylinder, which can drive the second vertical plate 3 to slide back and forth.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
