Technical Field

[0001] The utility model relates to the technical field of hook tongue processing for locomotives and vehicles, and in particular to a hook tongue S-surface processing positioning clamping device. Background Art

[0002] The coupler assembly is the main component used to connect locomotives and vehicles. The coupler assembly for locomotives and vehicles mainly consists of a hook body, a hook tongue, a hook tongue pin and hook cavity accessories. The hook tongue is provided with a hook tongue S surface. When vehicles are connected to each other or vehicles are connected to locomotives, the two hook tongue S surfaces are in contact, and the hook tongue S surface is prone to wear. During the hook tongue inspection and maintenance process, if the hook tongue S surface wear exceeds the limit, the hook tongue S surface of the hook tongue needs to be welded and repaired and then processed into the original shape by a planer to ensure that the hook tongue S surface of the hook tongue meets the requirements and improves the quality. The positioning and clamping device is a necessary device for operation processes such as accessory processing. During the accessory processing process, if the accessory is not positioned accurately, is not clamped, the clamping force is insufficient, or the positioning and clamping device is unreliable.

[0005] According to the technical solution provided in the embodiment of the present application, a hook tongue S-surface processing positioning clamping device includes a plurality of clamping assemblies, which are slidably mounted in corresponding slide grooves arranged on a workbench, so that the clamping blocks on the clamping assemblies move along the slide grooves, and are used for clamping and fixing the curved surface of the hook tongue;

[0006] The clamping assembly includes a moving mechanism, a slider, an adjustment mechanism and a clamping block. The moving mechanism is fixedly installed in a horizontal state in a slide groove, and the slider is movably installed on the screw rod on the moving mechanism, so that the moving mechanism drives the slider to move along the length direction of the screw rod, and the slider is also provided with an adjustment groove, in which the adjustment mechanism is movably installed, and the clamping block is installed at the front end of the connecting rod of the adjustment mechanism, so that the adjustment mechanism drives the clamping block to move along the adjustment groove, so that the clamping block clamps and fixes the hook tongue placed on the workbench.

[0007] Furthermore, the moving mechanism includes a rotating driving member and a screw rod, and the screw rod is fixedly connected to an output end of the rotating driving member so that the rotating driving member drives the screw rod to rotate.

[0008] Furthermore, a ball nut is fixedly installed at the bottom of the slider, and the ball nut is threaded onto the screw rod, so that the rotating driving member drives the slider to move linearly along the length direction of the screw rod.

[0009] Furthermore, the adjustment mechanism includes a piston, a connecting rod, and an elastic member. The connecting rod is fixedly mounted on the front end of the piston, and the elastic member is sleeved on the connecting rod between the piston and the clamping block so that the elastic member is used for the return of the piston.

[0010] Furthermore, the rear end of the slider is fixedly connected to the gas pipe, so that the gas pipe inputs the high-pressure gas into the regulating tank.

[0011] Furthermore, the clamping block is provided with a mounting groove, in which a clamping block is movably mounted, so that the clamping block can be rotated to clamp the curved surface of the hook tongue.

[0012] In summary, the beneficial effects of this application are:

[0013] First, by arranging a plurality of slide grooves on the workbench and installing corresponding clamping assemblies in each slide groove, the moving mechanism on each clamping assembly drives the slide block to move along the length direction of the screw rod, so that the plurality of clamping assemblies clamp and fix the curved surface of the hook tongue at different positions, thereby preventing the hook tongue from moving or sliding during the processing, and improving the processing efficiency of the curved surface of the hook tongue;

[0014] Second, by setting an adjustment mechanism on the slider on the clamping assembly, the gas pipe can input high-pressure gas into the adjusting groove, thereby pushing the piston to move along the adjusting groove, so that the connecting rod fixedly connected to the piston moves, so that the clamping block fixedly connected to the front end of the connecting rod can clamp the hook tongue of the curved surface to prevent the hook tongue from moving or sliding during the processing, thereby improving the curved surface processing efficiency of the hook tongue.
