Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict. For convenience of description, the words "upper", "lower", "left" and "right" in the following description are used only to indicate the correspondence between the upper, lower, left and right directions of the drawings themselves, and do not limit the structure.

As shown in fig. 1, the multi-station traverse car system provided by the present embodiment includes a traveling rail 3, a traverse car 4, a limit switch (not shown), a positioning mechanism 5, and a jacking mechanism 6. The traverser 4 can move between the corresponding stations of at least three production lines 1.

And a plurality of steel rail wheels 2 for bearing and transporting the die table are distributed on the production line 1. The rail wheels 2 are arranged side by side in pairs to form a group. The walking track 3 connects a plurality of production lines 1 in series in the direction vertical to the production lines 1. Two traveling rails 3 are provided with a traversing carriage 4 to form a group, and the production line 1 is provided with two parallel groups. The cross sliding vehicles 4 can move on the traveling rails 3, and the cross sliding vehicles 4 on the two groups of traveling rails 3 need to travel synchronously. The function of the trolley 4 is to transfer the mould table of one station of one production line 1 from this station to the corresponding station of the other production line 1.

The periphery of the bottom of the transverse moving vehicle 4 is provided with traveling wheels 41 matched with the traveling rails 3, wherein two traveling wheels 41 are driving wheels, and the other two traveling wheels 41 are driven wheels. The driving wheels in the travelling wheels 41 are in driving connection with a driving motor 42 arranged on the traverse carriage 4 in a gear engagement mode. The driving motor 42 is in signal connection with the limit switch.

As shown in fig. 1 and 2, the limit switch and the positioning mechanism 5 are disposed at corresponding stations of each production line 1, and in this embodiment, the limit switch and the positioning mechanism 5 are disposed near the traveling rail 3.

The limit switch can select a position sensor and is in signal connection with a driving mechanism of the transverse moving vehicle.

As shown in fig. 2 to 4, the positioning mechanism 5 includes a mounting seat 51 and a positioning bowl 52. And a positioning oil cylinder 43 with a cylinder barrel and a piston rod is arranged on the transverse moving vehicle 4. The cylinder barrel of the positioning oil cylinder 43 is arranged on a side plate of the cross sliding vehicle 4, and a piston rod of the positioning oil cylinder 43 can stretch relative to the cross sliding vehicle 4. The positioning bowl 52 is arranged beside the corresponding station through the mounting seat 51. The position of the positioning bowl 52 corresponds to the position of the positioning oil cylinder 43, so that the piston rod can be inserted into the positioning bowl 52 when extending out, and the transverse moving vehicle 4 can be reliably positioned mechanically.

The positioning bowl 52 comprises a bowl opening 521 and a bowl bottom 522, the bowl bottom 522 is an inner hemispherical surface, and the caliber of the bowl opening 521 is larger than that of the bowl bottom 522 so as to form a horn shape. The end of the piston rod of the positioning cylinder 43 is a ball head, and the ball head can be embedded into the inner hemispherical surface (as shown in fig. 4).

The positioning mechanisms are symmetrically arranged on two sides of the corresponding station, and the locking direction of the positioning mechanisms is perpendicular to the traveling direction of the transverse moving vehicle.

The positioning working principle of the multi-station transverse moving vehicle system is as follows: when the traverse car 4 travels to a station close to which parking is required, the limit switch sends a parking signal to the driving motor 42, the driving motor 42 stops driving the traverse car to move, and the traverse car stops near the limit switch under the action of inertia (initial positioning). The piston rods of the positioning oil cylinders 43 at the two ends of the traverse car 4 horizontally extend out of the traverse car at the same time, and in the process that the piston rod ball heads contact with the bowl walls of the positioning bowls 52 and continue to extend out, the friction force between the bowl walls and the piston rod ball heads generates two component forces in the direction along the walking track (namely the walking direction of the traverse car 4) and in the direction perpendicular to the walking track for the traverse car 4 through the positioning oil cylinders 43, wherein the component forces in the direction perpendicular to the walking track are mutually offset due to the symmetrical arrangement of the positioning oil cylinders 43, and the component force in the direction along the walking track can drive the traverse car to continue to move along the walking track until the piston rod ball heads are completely contacted with the inner hemispherical surface, so that the component forces disappear. From this, the sideslip car stops at the station (accurate positioning) that need berth, not only can improve the precision of berthhing, can also carry out the automatic correction with the deviation that the walking of two sideslip cars is asynchronous to arouse.

The cross sliding trolley 4 is provided with at least one jacking mechanism 6, the jacking mechanisms 6 are arranged in the middle of the cross sliding trolley 4 when the number of the jacking mechanisms 6 is one, and the jacking mechanisms 6 are arranged on two sides of the cross sliding trolley 4 when the number of the jacking mechanisms 6 is two. The jacking height of the jacking mechanism 6 is larger than the vertical height of the upper end surface of the steel rail wheel 2 and the ground, so that the die table is separated from the steel rail wheel 2 and then moves transversely along with the transverse moving vehicle 4. When the mould platform moves to a designated station, the mould platform descends and is placed on a steel rail wheel 2 of another production line 1.

As shown in fig. 2 and 3, the jacking mechanism 6 includes a jacking cylinder 61, a guide post 62 and a jacking platform 63. One end of the jacking oil cylinder 61 is connected with the cross sliding vehicle 4, and the other end is connected with the jacking platform 63. The guide post 62 is located on the side of the jacking cylinder 61, and the guide post 62 is connected with the cross sliding vehicle 4 and the jacking platform 63.
