Description

Technical Field

[0001] The utility model belongs to the field of square tube production, in particular to a clamp for fixing the square tube. Background Art

[0002] After the square tube is produced, a blade is used to cut the square tube as needed to meet the length assembly requirements.

[0003] For the cutting of square tubes, firstly, the square tubes must be fixed with a clamping tool, and then they are cut. The current method of clamping and fixing square tubes is to place the square tubes in a U-shaped block, then set a pressure plate on the U-shaped block, and then use the screws on the pressure plate to press down the square tubes to fix them. This clamping and fixing method is complicated and not convenient for fixing square tubes. In addition, the shear force on the square tubes during cutting is horizontal and vertical to the length of the square tubes, or tilted downward. The square tubes are fixed by pressing down with screws. To prevent the square tubes from shaking due to the force, the square tubes need to be pushed forward to make them close to the side of the U-shaped block facing the cutter, and the square tubes need to be horizontally limited to prevent shaking. This operation makes it inconvenient to clamp the square tubes. Utility Model Content

[0023] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0024] like Figure 1 , 2As shown, a square tube fixing clamp includes a first vertical plate 2, a second vertical plate 8 and a pressure plate 4, wherein the first vertical plate 2 and the second vertical plate 8 are arranged opposite to each other on the base 1, and the pressure plate 4 is arranged across the first vertical plate 2 and the second vertical plate 8. The proximal end of the pressure plate 4 is rotatably installed on the top of the first vertical plate 2 through a rotating shaft, and the distal end of the pressure plate 4 overlaps the top of the second vertical plate 8. A quick-lock clamp 9 is provided on the outer side of the second vertical plate 8, and the pressure plate 4 and the second vertical plate 8 are connected and fixed by the quick-lock clamp 9.

[0025] The space between the first vertical plate 2 and the second vertical plate 8 is provided with a first wedge block 5 and a second wedge block 7. The bevel angles of the first wedge block 5 and the second wedge block 7 match each other, for example, the bevel angle is 15°. The square tube 3 to be processed is placed between the first vertical plate 2 and the second vertical plate 8. The square tube 3 is close to the inner side of the first vertical plate 2. The vertical surface of the second wedge block 7 is close to the inner side of the second vertical plate 8. The bevel of the second wedge block 7 corresponds to the square tube 3. A tapered mouth structure with a large mouth facing upward is formed between the second wedge block 7 and the square tube 3. The first wedge block 5 is inserted between the square tube 3 and the second wedge block 7. The bevel of the first wedge block 5 is close to the bevel of the second wedge block 7, and its vertical surface is close to the square tube 3. The pressing plate 4 is provided with a fastener, which is preferably a hand screw 6, and is threadedly connected to the pressing plate 4. The bottom end of the fastener is tightly against the first wedge block 5.

[0026] In the utility model, the first wedge block 5 and the second wedge block 7 match and are pressed down and fixed by the hand screw 6, so that the square tube is quickly clamped and fixed. At the same time, because the square tube 3 is close to the first vertical plate 2, the lateral limitation of the square tube 3 is achieved to prevent the square tube from shaking when it is cut, thereby ensuring the stability of the square tube processing.

[0027] In the present invention, the bottoms of the first vertical plate 2 and the second vertical plate 8 are connected by a bottom plate 10 to form a U-shaped block structure. Figure 3 As shown, the bottom plate is provided with a countersunk hole so that the U-shaped block can be mounted on the base 1 using a countersunk screw; a positioning groove 81 is provided on the top of the second vertical plate 8, and the far end of the pressing plate 4 is located in the positioning groove 81 when fixed and clamped.

[0028] In the utility model, the pressure plate 4 is structured as follows Figure 4 As shown, the far end of the pressing plate 4 is provided with a hook 41 corresponding to the quick-locking clamp 9. This structure facilitates the quick-locking clamp 9 to lock and fix the pressing plate 4.

[0029] In order to improve the versatility of the utility model, the utility model is also matched with multiple gaskets. When the size of the square tube 3 is small, according to the clamping needs, a gasket is placed between the second wedge block 5 and the square tube 3 and / or between the second wedge block 7 and the second vertical plate 8, thereby adjusting the position of the second wedge block 5 and the first wedge block 7, so that the hand screw 6 can face the second wedge block 5, and then press the second wedge block 5 down and fix it.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
