DETAILED DESCRIPTION

[0017] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0018] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] Connecting rod bearing processing fixed tooling, such as Figure 1 and Figure 2 As shown, a turntable 5 is fixedly provided on the upper end surface of the bottom plate 1 through a bearing base 2, and the turntable 5 is fixedly connected to a horizontally placed rotary connecting rod bearing placement cylinder 3, one end of the rotary connecting rod bearing placement cylinder 3 is fixed on the turntable 5, and the other end is suspended. The turntable 5 is rotated on a vertical plane through a rotary motor 6 fixed on the bottom plate 1, so when the turntable 5 rotates, it will drive the rotary connecting rod bearing placement cylinder 3 to rotate on the vertical plane.

[0020] like Figure 2 and Figure 3 As shown, the connecting rod bearing fixing device 4 is located in the rotating connecting rod bearing placement cylinder 3, the transmission device 42 on the connecting rod bearing fixing device 4 is fixed on the turntable 5, the transmission rod 41 on the connecting rod bearing fixing device 4 is located on the central axis of the rotating connecting rod bearing placement cylinder 3, one end of the transmission rod 41 is rotatably connected to the turntable 5 through an annular cylinder, and a plurality of fixing rods 43 are connected to the transmission rod 41 through a connecting rod 44 and a compression spring 8, the two ends of the connecting rod 44 are respectively hinged to the fixing rod 43 and the transmission rod 41, and each fixing rod 43 is fixedly connected to the inner wall of the rotating connecting rod bearing placement cylinder 3 through a telescopic rod 7, and the motor shaft of the transmission device 42 is fixedly connected to the transmission rod 41, so that the transmission rod 41 can rotate with the start of the transmission device 42;

[0021] like Figure 1 As shown, a turning tool 9 for machining the end of the connecting rod bearing which can slide back and forth is provided on the upper end surface of the base plate 1.

[0022] Before use, first slide the turning tool 9 away from the rotating connecting rod bearing placement tube 3, and then place the connecting rod bearing to be turned in the gap between the connecting rod bearing fixture 4 and the rotating connecting rod bearing placement tube 3, that is, the connecting rod bearing placed above the connecting rod bearing fixture 4 has an opening downward, and the connecting rod bearing placed below the connecting rod bearing fixture 4 has an opening upward. When placing, the part to be turned is located outside the rotating connecting rod bearing placement tube 3.

[0023] Then start the transmission device 42, such as Figure 3 As shown, the transmission rod 41 rotates counterclockwise. Since the fixing rod 43 is fixedly connected to the inner wall of the rotating connecting rod bearing placement tube 3 by the telescopic rod 7, the fixing rod 43 is limited to move only up and down, and cannot move left and right. Therefore, when the transmission rod 41 rotates counterclockwise, the angle between the connecting rod 44 and the fixing rod 43 decreases, and the angle between the connecting rod 44 and the transmission rod 41 increases, so that the fixing rod 43 moves up until the fixing rod 43 abuts against the connecting rod bearing placed in the rotating connecting rod bearing placement tube 3, so that the fixing rod 43 and the inner wall of the rotating connecting rod bearing placement tube 3 clamp the connecting rod bearing, thereby fixing the connecting rod bearing.

[0024] At this time, stop the transmission device 42 and start the rotating motor 6 to rotate the turntable 5, thereby driving the rotating connecting rod bearing placement tube 3, the connecting rod bearing fixing device 4 and the clamped connecting rod bearing to rotate on the vertical plane. At this time, slide the turning tool 9 so that the turning tool 9 moves to the end face of the connecting rod bearing, so that the side end face of the connecting rod bearing can be turned.

[0025] When in use, in order to achieve stability between the fixing rod 43 and the inner wall of the rotating connecting rod bearing placement tube 3, the telescopic rod 7 can be set as a telescopic plate, and the telescopic rod 7 can be used to achieve the limiting of the placed connecting rod bearing.

[0026] The above description is only an explanation of the preferred embodiments of the present application and the technical principles and other schemes used. At the same time, the scope of the invention involved in the present application is not limited to the technical scheme formed by a specific combination of the above technical features, but also should cover other technical schemes formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with the technical features with similar functions disclosed in the present application (but not limited to) by each other to form a technical scheme.
