In the figure: 1. a base; 2. a support block; 3. a clamping table; 4. a gap; 5. a step; 6. a corner cylinder; 7. a horizontal cylinder; 8. a compression head; 9. a compression plate; 10. a block for raising; 11. an I-shaped section.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Examples

As shown in fig. 1, the fixture for clamping an i-shaped profile provided by this embodiment includes a base 1, the base 1 is a rectangular plate, a plurality of corner cylinders 6 arranged side by side are fixedly installed at the bottom of one side of the base 1, a plurality of supporting blocks 2 are further fixedly connected to the bottom of the base 1, a clamping table 3 is fixedly connected to the top of the base 1, the clamping table 3 includes two supporting seats arranged oppositely, a gap 4 is left between the two supporting seats, an inwardly recessed step 5 is opened in the middle of one side of one of the supporting seats close to the gap 4, a fillet is inverted at the top, a plurality of horizontal cylinders 7 arranged side by side are arranged at one side of the clamping table 3 away from the corner cylinders 6, a block 10 is connected to the bottom of the horizontal cylinder 7, the block 10 is fixed on the surface of the base 1, a rotary telescopic end of the corner cylinder 6 is connected with a pressing head 8, the telescopic end of, and a compression plate 9 is attached.

The utility model discloses the clamping process:

for convenience of describing the clamping process, the h-shaped section bar 11 is divided into three parts, namely: the device comprises a vertical plate, a long transverse plate connected with one end of the vertical plate, and a short transverse plate connected with the other end of the vertical plate;

the pressing head 8 connected with the corner cylinder 6 is positioned outside the clamping table 3, and the pressing plate 9 connected with the horizontal cylinder 7 is retracted into the supporting seat of the clamping table 3, and the state is the idle state of the utility model at the moment; as shown in fig. 2 and 3, during clamping, a short transverse plate of an i-shaped section bar 11 is placed into a gap 4 between two supporting seats of a clamping table 3 from above the gap 4, because a horizontal cylinder 7 is arranged on the surface of a heightening block 10, the horizontal cylinder 7 heightened by the heightening block 10 corresponds to the vertical plate of the placed i-shaped section bar 11, namely a pressing plate 9 connected with the horizontal cylinder 7 corresponds to the vertical plate of the i-shaped section bar 11, the horizontal cylinder 7 is started, the horizontal cylinder 7 pushes the pressing plate 9 to move towards the vertical plate of the i-shaped section bar 11, then the pressing plate 9 presses the vertical plate of the i-shaped section bar 11 on the side wall of the supporting seat, at the moment, the side wall of the short transverse plate of the i-shaped section bar 11 is tightly attached to the step 5 surface of the supporting seat, then a corner cylinder 6 is started, the corner cylinder 6 drives the pressing head 8 to rotate 90 degrees and then is positioned above the clamping table 3, then the corner cylinder 6 presses the, pressing a long transverse plate of the I-shaped section bar 11 on the surface of the supporting seat, thereby completing the clamping work; the top of the supporting seat provided with the step 5 is chamfered with a fillet, the fillet corresponds to the joint of the vertical plate and the long transverse plate of the I-shaped section bar 11 after clamping, the contact between the joint and the corner of the supporting seat of the clamping table 3 after clamping is avoided after the fillet is chamfered, so that the workpiece is extruded by external force in other directions, the workpiece is clamped unstably, the chamfered fillet avoids the joint of the vertical plate and the long transverse plate of the I-shaped section bar 11, the I-shaped section bar 11 is only subjected to horizontal pressing force given by the pressing plate 9 and vertical pressing force given by the pressing head 8, the uniform stress after the I-shaped section bar 11 is clamped is ensured, and the clamping of the I-shaped section bar 11 is more stable.
