[0027] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0028] like Figure 1 As shown, the utility model discloses an embodiment of a clamping device 1, including a pressing arm 11, a pressing column 12, a clamping nut 13 and a clamping drive mechanism 14, one end of the pressing arm 11 is provided with a strip hole 111 adapted to the pressing column 12, the clamping nuts 13 are respectively arranged at both ends of the strip hole 111, the pressing column 12 passes through the strip hole 111, and is threadedly connected to the clamping nuts 13 on both sides of the pressing arm 11, so that the clamping nuts 13 on both sides of the pressing arm 11 clamp the pressing arm 11; the other end of the pressing arm 11 is connected to the clamping drive mechanism 14, and the clamping drive mechanism 14 is used to drive the pressing arm 11 to drive the pressing column 12 to clamp the surface of the object.

[0029] The present embodiment is provided with a strip hole 111 that is adapted to the pressure column 12 at one end of the pressure arm 11, and a clamping nut 13 is respectively provided at both ends of the strip hole 111. The pressure column 12 passes through the strip hole 111 and is connected with the clamping nut 13, so that the clamping nuts 13 at both ends of the strip hole 111 clamp the pressure arm 11, and the pressure driving mechanism 14 located at the other end of the pressure arm 11 drives the pressure arm 11 to rotate, and the pressure arm 11 drives the pressure column 12 to press a position on the surface of the object; by rotating the pressure column 12 or the clamping nut 13, the clamping nut 13 and the pressure arm 11 are loosened, and the position of the pressure column 12 in the strip hole 111 can be adjusted, and the pressure column 12 or the clamping nut 13 is rotated to make the clamping nut 13 clamp the pressure arm 11 again. At this time, the clamping driving mechanism 14 drives the pressure arm 11 to rotate and can drive the pressure column 12 to press other positions; this embodiment realizes the clamping positioning of crossbeams and longitudinal beams of different widths by adjusting the clamping position of the pressure column 12.

[0030] Preferably, the strip-shaped hole 111 is extended along the length direction of the pressing arm 11 to better adapt to pressed objects of different widths.

[0031] In addition, combined Figure 3 and Figure 4 The present invention also discloses another embodiment of a clamping device 1, wherein the clamping nut 13 is provided with a slide groove 131 adapted to the pressure arm 11, and the extension direction of the slide groove 131 is the same as the extension direction of the strip-shaped hole 111. The clamping nut 13 of this embodiment includes a body and a backing plate, which can be integrally formed with the backing plate or separately formed. The slide groove 131 is formed on the backing plate.

[0032] A slide groove 131 is provided on the clamping nut 13. On the one hand, when the clamping nut 13 is clamped to the pressure arm 11, the clamping nut 13 can be prevented from rotating while the pressure column 12 is rotating to loosen the clamping nut 13 and the pressure arm 11. On the other hand, it can help the pressure column 12 to translate in the strip hole 111 to prevent the pressure column 12 from deflecting.

[0033] The pressure column 12 of this embodiment includes a stud section 121 and a pressure head 122. The pressure head 122 is arranged at one end of the stud section 121 away from the clamping nut 13, and the pressure head 122 protrudes toward the side wall of the stud section 121 to increase the area of ​​the pressure column 12 acting on the object.

[0034] Preferably, in this embodiment, the threaded directions of the clamping nuts 13 arranged at both ends of the strip hole 111 are opposite. By rotating the pressure column 12, the clamping nuts 13 at both ends of the strip hole 111 can be synchronously moved closer or farther away, thereby quickly clamping or loosening the pressure arm 11.

[0035] The compression drive mechanism 14 of this embodiment specifically includes a connecting base 141, a connecting arm 142, and a driving arm 143. The connecting base 141 is provided with a first hinge axis and a second hinge axis, and the driving arm 143 is provided with a third hinge axis and a fourth hinge axis. The two ends of the connecting arm 142 are respectively rotatably connected to the first hinge axis and the third hinge axis. The compression arm 11 is provided with two hinge holes rotatably connected to the second hinge axis and the fourth hinge axis. The arrangement direction of the two hinge holes on the compression arm 11 is preferably arranged to intersect the extension direction of the strip hole 111, so that the force of the driving arm 143 is better transmitted to the compression arm 11 and the compression column 12.

[0036] In addition, the present invention also provides an embodiment of a walkway plate welding positioning device, which includes a positioning platform 2, a positioning seat 3 provided on the positioning platform 2, and the aforementioned pressing device 1. The positioning seat 3 has a support surface a and an abutment surface b intersecting with the support surface a. The pressing column 12 of the pressing device and the abutment surface b are respectively abutted against two opposing surfaces of the pressed part. This walkway plate welding positioning device can conveniently press and position crossbeams and longitudinal beams of different widths.

[0037] Among them, the positioning seat 3 on the positioning platform 2 specifically includes a crossbeam positioning seat 31, a longitudinal beam positioning seat 32 and a corner positioning seat 33. The crossbeam positioning seat 31 is used to position and support the crossbeam of the walkway plate, the longitudinal beam positioning seat 32 is used to position and support the longitudinal beam of the walkway plate, and the corner positioning seat 33 is used to position and support the end of the longitudinal beam and the end of the crossbeam close to the end of the longitudinal beam.
