[0019] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this 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.
[0020] Please read Figure 1-4The utility model provides a technical solution: a forging and forming processing device for a railway freight car coupler frame, comprising a support plate 1, characterized in that a fixed power mechanism 2 is provided above the support plate 1, the support plate 1 is provided with a central shaft 3 passing vertically therethrough, the force output by the power mechanism 2 acts on the central shaft 3, a rotating member 4 is provided below the support plate 1, the rotating member 4 is sleeved on the central shaft 3 and can rotate around the central shaft 3, the rotating member 4 is fixed in height to the support plate 1, the central shaft 3 has a groove in the contact area with the rotating member 4, the rotating member 4 has a protrusion in the contact area with the central shaft 3, the protrusion can slide in the groove, a plurality of rollers 5 are provided on the central shaft 3, the rollers 5 are connected to the central shaft 3 through bearings, symmetrical clamping arms 6 are provided on both sides of the central shaft 3, the upper ends of the clamping arms 6 are in the shape of an incomplete gear, the upper ends of the clamping arms 6 are engaged with the grooves formed by the rollers 5 on the central shaft 3, a connecting frame 7 is fixed below the rotating member 4, the connecting frame 7 is connected to the clamping arm 6 through a bearing.
[0021] The power mechanism 2 is a cylinder, and the output shaft of the cylinder is fixedly connected to the central shaft 3.
[0022] The rotating member 4 is connected to the support plate 1 through a bearing.
[0023] The groove of the central shaft 3 includes a vertical track and an inclined track, which are unfolded into two inclined N-first connected shapes in a plane.
[0024] The protrusion of the rotating member 4 is an irregular polyhedron, and the initial position of the protrusion is at the top end of the groove of the central shaft 3.
[0025] The number of the plurality of rollers 5 is four, and they are arranged equidistantly in the vertical direction at the lower end of the central axis.
[0026] Elastic pads 8 fixed with screws are provided on opposite sides of the clamping portion at the lower end of the clamping arm 6.
[0027] Working principle: Fix the support plate 1 on the robot arm, use the robot arm to align the device with the workpiece to be turned, start the cylinder 2, and the cylinder 2 works to lift the center shaft 3 upward. The center shaft 3 drives the roller 5 to rise, and the roller 5 drives the clamping arm 6 to rotate around the bearing. The relative position distance of the lower end of the clamping arm 6 is shortened, thereby clamping the workpiece. At the same time, during the rising process of the center shaft 3, since the height distance between the rotating part 4 and the support plate 1 remains unchanged, the protrusion of the rotating part 4 rotates horizontally along the inclined track under the force of the groove of the center shaft 3. The rotating part 4 transfers the force to the workpiece and roller 5 through the connecting frame 7 and the clamping arm 6. The roller 5 rotates 18 around the center shaft 3. After 0 degrees, the protrusion of the rotating part 4 hits the inner wall of the vertical guide rail of the groove of the central shaft 3, the rotating part 4 stops rotating, and the workpiece is turned around; the cylinder 2 is closed, the central shaft 3 drops, the roller 5 drops, and the roller 5 drives the clamping arm 6 to rotate around the bearing. The relative position distance of the lower end of the clamping arm 6 increases, and the clamping arm 6 releases the workpiece. At the same time, because the height distance between the rotating part 4 and the support plate 1 remains unchanged, the protrusion of the rotating part 4 slides and rises vertically relative to the central shaft 3 in the groove of the central shaft 3, and when the protrusion slides to the top of the groove, it is pushed away from the vertical track by the inclined surface of the top of the groove, ensuring that the protrusion will slide along the inclined track after the cylinder is started next time.
