The transverse transmission device includes a motor and a lead screw, one end of the lead screw is in transmission connection with the output end of the motor, the other end of the lead screw is threaded with the carriage, and the axial direction of the lead screw is in line with the The extending directions of the grooves are consistent.

Further, a connecting shaft extends from one end of the lead screw connected to the motor, and a bearing seat is provided on the workbench, and the connecting shaft passes through the bearing seat and is fixedly connected to the output end of the motor. A shaft coupling is provided between the shaft and the output end of the motor, and a bearing is provided between the connecting shaft and the bearing seat. The bearing seat and the bearing are used to support the lead screw. The motor drives the lead screw through the coupling, and the lead screw It is threadedly connected with the carriage, so the positive and negative rotation of the motor can realize the reciprocating movement of the carriage on the lower mold base.

The beneficial effects of the utility model are: the multi-station press of the utility model adopts the threaded connection between the lead screw and the slide frame to replace the traditional cam mechanism to drive the slide frame. The stability and precision of the reciprocating motion of the frame achieve the effect of smooth transmission of workpieces, and avoid the phenomenon of workpieces dropping or running wrong during work.

detailed description

Now in conjunction with accompanying drawing, the utility model is described in further detail. These drawings are all simplified schematic diagrams, and only schematically illustrate the basic structure of the utility model, so they only show the configurations related to the utility model.

Example 1

As shown in Figures 1-3, a multi-station press includes a longitudinal power assembly and a workbench 1 below it, the longitudinal power assembly has a main shaft 2 capable of reciprocating up and down for outputting pressure, the main shaft The lower end of 2 is fixed with an upper mold base 3, and the lower mold base 4 is fixed directly below the upper mold base 3 on the workbench 1, and a slide frame 5 is slidably connected to the lower mold base 4, and the slide frame 5 There is a groove 6 on the top, and clamping devices 7 are fixed on both sides of the groove 6, and a row of stamping heads 8 is arranged on the lower surface of the upper mold base 3 along the extending direction of the groove 6, so that The workbench 1 is provided with a transverse transmission device;
