[0017] 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.

[0018] 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.

[0019] 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.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, a connecting rod joint shaft hole processing device of this embodiment comprises a base 1, a cylinder 2 and a clamping device 3 are arranged on the surface of the base 1, the cylinder is located in the middle of the base, the clamping device 3 is located outside the cylinder 2, an opening 21 is arranged on the side of the cylinder 2, the opening 21 and the clamping device 3 are located on the same side of the cylinder 2, and a plurality of adjusting screws 4 are arranged on the side wall of the cylinder 2, the adjusting screws 4 are threadedly connected with the cylinder 2, and the adjusting screws 4 point to the center of the cylinder 1. The surface of the base is arranged vertically, the axis of the cylinder 2 is horizontal, and the center line of the opening 21 is located in the upper half of the cylinder 2, that is, after the connecting rod joint is fixed, the shaft hole end of the connecting rod joint faces downward and the body part faces upward, and is placed obliquely in the cylinder 2. Under the tilting effect, it is convenient for the cylinder 2 and the adjusting screw 4 to quickly and accurately position the shaft hole of the connecting rod joint, so that the shaft hole is coaxial with the cylinder 2, which is conducive to ensuring the machining accuracy of the shaft hole.

[0021] During operation, the axial hole of the connecting rod joint is placed in the cylinder 2, and the main body passes through the opening 21 and extends to the outside of the cylinder. The axial hole is made coaxial with the cylinder by adjusting the adjusting screw 4. The clamping device 3 clamps the main body to fix the connecting rod joint on the surface of the base 1, which is convenient for the tool to process the axial hole and one end face of the axial hole.

[0022] After the connecting rod joint is fixed to the surface of the base 1, a cavity is provided between the axial hole of the connecting rod joint and the base 1, and the cavity is convenient for the tool to process the axial hole of the connecting rod joint. The cavity can be a groove on the surface of the base coaxial with the cylinder 2, or formed by providing an annular connecting block coaxial with the cylinder 2 between the base 1 and the cylinder 2.

[0023] The clamping device 3 is a clamping cylinder, through which the body of the connecting rod joint can be clamped, thereby fixing the connecting rod joint; or the clamping device 3 includes a clamping block 31, a bolt 32 and a locking nut 33, the bolt 32 passes through the clamping block 31 and is fixedly connected to the base 1, and the locking nut 33 is threadedly connected to the bolt 32. By tightening the locking nut 33, the clamping block 31 applies a certain pressure to the body of the connecting rod joint, thereby clamping and fixing the connecting rod joint.

[0024] The surface of the base 1 is provided with a cushion block 5, which supports the end of the connecting rod joint body, so that the axis of the connecting rod joint body is parallel to the base, ensuring the processing accuracy of the shaft hole.

[0025] An elastic device 6 is provided on the outside of the opening 21, and the elastic device 6 is located between the opening 21 and the cushion block 5. A switch is provided below the elastic device 6, and the switch is electrically connected to a driving device for driving the tool through a PLC controller, thereby controlling the tool to start moving; the elastic device 6 can be a spring sheet. When the connecting rod joint is placed in the cylinder 2, the elastic device 6 provides a supporting force to the main body of the connecting rod joint, so that the connecting rod joint does not contact the switch below the elastic device 6. After the clamping device 3 is actuated, the clamping device 3 presses down the main body of the connecting rod joint and the elastic device 6, so that the elastic device 6 contacts the switch, and the switch is connected to the PLC controller. The PLC controller controls the tool to start moving and processes the shaft hole.

[0026] 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.
