DETAILED DESCRIPTION

[0019] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0020] See also Figure 1 and Figure 2 This rail vehicle metal plate end through-hole chamfering limit mechanism has a support bracket 2 fixed on the base plate 1, and a rotatable mounting plate 4 is movably mounted on the bracket 2. A bearing seat 3 is used between the mounting plate 4 and the bracket 2 for movably mounting. The two mutually perpendicular mounting surfaces on the mounting plate 4 can be used to install a limit seat, which is used to fix the metal plate.

[0021] The support plate 5 of the limit seat is the main structure. The first cylinder 6 fixed on the support plate 5 can drive the right-angled pressing plate 7 to move up and down. The upper end of the pressing plate 7 can press and fix the metal plate.

[0022] The pad 8 below the pressing plate 7 is used to support the metal plate and plays a role of auxiliary support.

[0023] Furthermore, the outer vertical end plate of the pad (8) has a concave slot in the middle.

[0024] The vertical end plate outside the pad 8 serves to limit the outer side of the plate, and the groove in the middle can support the protrusion at the lower end of the plate.

[0025] The other end of the support plate 5 is provided with an end limit plate 9, which can provide a limit for one end of the plate.

[0026] The second cylinder 10 installed under the support plate 5 is used to drive the movable end plate 11 to move horizontally, and is used to limit the other end of the plate. The movable end plate 11 must exceed the upper edge of the support plate 5 to ensure that it can contact the end of the plate. The movable end plate 11 is only pressed against the side of the end plate without an opening and will not interfere with the chamfering mechanism.

[0027] The third cylinder 12 installed on one side of the support plate is used to drive the top block 13 to move forward and to press it against the side wall of the plate. Combined with the vertical end plate at the outer end of the cushion block 8, the workpiece can be fixed and locked.

[0028] The driving motor 15 drives the linkage shaft 14 on one of the brackets 2 to rotate through a belt and a pulley. The linkage shaft 14 is fixedly connected to the mounting plate 4. Driven by the driving motor 15, a certain limit seat can be located directly above. At this time, the corresponding chamfering machine can chamfer the through hole at the end of the plate. At this time, the workpiece can be replaced on the other set of limit seats, which is convenient for subsequent cyclic processing.

[0029] The working principle of this utility model is as follows:

[0030] This metal plate end through-hole chamfering limiting mechanism for rail vehicles, when installing the plate, first the third cylinder 12 drives the top block 13 to move backward, the first cylinder 6 drives the pressure plate 7 to rise, the second cylinder 10 drives the movable end plate 11 to move outward, and the plate is placed from under the pressure plate 7, one end of which is against the inner side of the end limit plate 9, then the first cylinder 6, the second cylinder 10 and the third cylinder 12 are reset, so that the top block 13 is against the side wall of the plate, the pressure plate 7 is pressed tightly against the top of the plate, and the movable end plate 11 is against one end of the plate, completing the all-round fixation of the plate. When the plate needs to be removed, only the reverse operation is required.

[0031] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense, and may refer to mechanical or electrical connections, internal communication between two components, or direct connection. "Up," "down," "left," and "right" are only used to indicate relative positional relationships. When the absolute positions of the objects being described change, the relative positional relationships may also change.

[0032] Secondly: The drawings of the embodiments disclosed in this utility model only involve structures related to the embodiments disclosed in this utility model. Other structures can refer to common designs. In the absence of conflicts, the same embodiment and different embodiments of the utility model can be combined with each other.

[0033] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
