[0024] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0025] according to Figure 1 、 2 As shown in Figures 3, 4, and 5, a clamping tool for square tube processing is proposed in this embodiment, comprising a workbench 1 and a first square tube clamp 2 provided on the upper end of the workbench 1, the first square tube clamp 2 being detachably connected to the workbench 1, two sliding seats 3 being provided on the left and right sides of the workbench 1, a second square tube clamp 4 being provided on the upper end of the sliding seat 3, and the second square tube clamp 4 being detachably connected to the sliding seat 3;

[0026] The longitudinally arranged square tube is fixed by the first square tube clamp 2 at the upper end of the workbench 1, and the transversely arranged square tube is fixed by the second square tube clamp 4 on the sliding seat 3. The sliding seat 3 is arranged on the left and right sides of the workbench 1. When fixing the square tube, the staff can clamp the square tube from the left and right sides of the workbench 1 at the same time, thereby improving work efficiency.

[0027] Two first inclined surfaces 7 are provided on the lower end surface of the workbench 1. The first inclined surfaces 7 are placed on the left and right sides of the workbench 1. The workbench 1 is in an inverted trapezoid. A second inclined surface 8 is provided on one end of the sliding seat 3 facing the workbench 1. The second inclined surface 8 is slidably connected to the first inclined surface 7. A sliding control mechanism for adjusting the distance between two adjacent sliding seats 3 is provided at the connection between the first inclined surface 7 and the second inclined surface 8.

[0028] By adjusting the distance between the two sliding seats 3 through the sliding control mechanism, the fixed position of the square tube can be changed. Since the first inclined surface 7 is provided on the lower end surface of the workbench 1, the second inclined surface 8 that slides with the first inclined surface 7 is also located at the lower end of the workbench 1. Therefore, when the sliding seat 3 slides, the debris generated by the pipe processing on the workbench 1 and the sliding seat 3 will not fall to the matching position of the first inclined surface 7 and the second inclined surface 8, thereby improving the service life of the workbench 1 and the sliding seat 3.

[0029] The first square tube clamp 2 and the second square tube clamp 4 both include a tube sleeve 12, at least two elastic bolts 15 are provided on the top of the tube sleeve 12, the elastic bolts 15 pass through the tube sleeve 12 and are threadedly connected to the tube sleeve 12, bolt plates 13 are provided on both sides of the tube sleeve 12, at least two mounting bolts 14 are assembled on the bolt plate 13, the mounting bolts 14 are threadedly connected to the bolt plate 13, and bolt holes threadedly connected to the mounting bolts 14 are opened at the upper end of the workbench 1 and the upper end of the sliding seat 3.

[0030] The square tube to be fixed is passed through the tube sleeve 12, and the tension bolt 15 at the top of the tube sleeve 12 is screwed into the tube sleeve 12. The tension bolt 15 squeezes the tube to secure it. The tube sleeve 12 is fixed to the workbench 1 and the sliding seat 3 using a bolt connection. When removing the tube sleeve 12 from the workbench 1 and the sliding seat 3 for replacement, the mounting bolt 14 on the bolt plate 13 is unscrewed from the bolt hole provided at the top of the workbench 1 and the sliding seat 3.

[0031] For the specific structure of the slip control mechanism, please refer to the following description.

[0032] The sliding control mechanism includes a sliding part and a control part:

[0033] The sliding member includes an adjusting groove 9 and a matching block 11. The adjusting groove 9 is provided on the first inclined surface 7. The matching block 11 is fixedly connected to the second inclined surface 8. The matching block 11 is inserted into the adjusting groove 9 and is slidably connected to the adjusting groove 9.

[0034] The control part includes an adjusting handle 6 and a double-headed screw 10. The double-headed screw 10 is placed in the adjusting groove 9. The double-headed screw 10 passes through the two matching blocks 11 in the adjusting groove 9. The matching blocks 11 are threadedly connected to the double-headed screw 10. Both ends of the double-headed screw 10 are rotatably connected to the workbench 1. The adjusting handle 6 is placed on the outside of the workbench 1. The adjusting handle 6 is fixedly connected to the double-headed screw 10 through a connecting shaft.

[0035] When adjusting the distance between two adjacent second square tube clamps 4, rotate the adjusting handle 6, and the adjusting handle 6 will drive the double-headed screw 10 in the adjusting groove 9 to rotate together. During the rotation of the double-headed screw 10, it cooperates with the two matching blocks 11, and the two matching blocks 11 move along the rod of the double-headed screw 10. Due to the different rotation directions of the two threads on the outside of the double-headed screw 10, the matching blocks 11 that cooperate with the two threads will move in opposite directions along the rod of the double-headed screw 10 to adjust the distance between the two sliding seats 3.

[0036] It is worth further explaining that the mating block 11 is a T-shaped slider, and the adjustment slot 9 is a T-shaped slot that matches the T-shaped slider. The T-shaped slider and the T-shaped slot form a jagged, interlocking structure, thereby increasing the contact area between the mating block 11 and the adjustment slot 9, improving the stability of the mating block 11 as it slides along the adjustment slot 9, and also preventing the mating block 11 from detaching from the adjustment slot 9, thereby improving the safety of the sliding seat 3.

[0037] To facilitate the collection of dust and debris on the workbench 1 and the sliding seat 3 and prevent dust from dispersing, in a preferred embodiment, a dust cleaning channel 16 is provided on the side of the upper end surface of the sliding seat 3 near the second inclined surface 8. The ends of the dust cleaning channel 16 extend to both sides of the sliding seat 3. A dust box 17 is provided on the outside of the sliding seat 3. The dust box 17 is placed below the second inclined surface 8 and is detachably connected to the sliding seat 3. When cleaning the workbench 1 and the sliding seat 3, a brush is used to sweep the dust and debris into the dust cleaning channel 16. The dust swept into the dust cleaning channel 16 is then swept into the dust box 17 from both ends of the cleaning channel 16 by the brush. The detachable connection of the dust box 17 facilitates the removal of dust.

[0038] It is worth further explaining that a baffle 19 is provided at the upper end of the dust box 17. The baffle 19 is fixedly connected to the left and right sides of the dust box 17. The baffle 19 is snapped into a hook 18 provided on the outside of the sliding seat 3, and the hook 18 is fixedly connected to the sliding seat 3. The hook 18 is fixed to the sliding seat 3, and a groove is formed at the top of the hook 18 to allow the baffle 19 to be snapped into it. When removing the dust box 17 from the sliding seat 3, the dust box 17 is pulled upward to disengage the baffle 19 from the hook 18.

[0039] In a preferred embodiment, a support frame 5 is provided at the lower end of the workbench 1. The support frame 5 comprises multiple upright posts and multiple horizontal posts. The tops of the upright posts are fixedly connected to the workbench 1, and the horizontal posts are positioned between two adjacent upright posts and are fixedly connected to the upright posts. The support frame 5 is fixedly connected to the lower end of the workbench 1 to support the workbench 1. To enhance the stability of the workbench 1, anti-slip rubber rings may be provided at the bottom of the upright posts to increase friction between the support frame 5 and the ground.

[0040] How this application works:

[0041] The longitudinally arranged square tube is fixed by the first square tube clamp 2 at the upper end of the workbench 1, and the transversely arranged square tube is fixed by the second square tube clamp 4 on the sliding seat 3. The sliding seat 3 is arranged on the left and right sides of the workbench 1. When fixing the square tube, the staff can clamp the square tube from the left and right sides of the workbench 1 at the same time, thereby improving work efficiency.

[0042] By turning the adjusting handle 6, the adjusting handle 6 will drive the double-headed screw 10 in the adjusting groove 9 to rotate together. During the rotation of the double-headed screw 10, it will cooperate with the two matching blocks 11, and the two matching blocks 11 will move along the rod of the double-headed screw 10. Since the two threads on the outside of the double-headed screw 10 rotate in opposite directions, the matching blocks 11 that cooperate with the two threads will move in opposite directions along the rod of the double-headed screw 10, adjusting the distance between the two sliding seats 3 and changing the fixed position of the square tube. Since the first inclined surface 7 is provided on the lower end surface of the workbench 1, the second inclined surface 8 that slides with the first inclined surface 7 is also at the lower end of the workbench 1. Therefore, when the sliding seat 3 slides, the debris generated on the workbench 1 and the sliding seat 3 due to pipe processing will not fall to the matching point between the first inclined surface 7 and the second inclined surface 8, thereby improving the service life of the workbench 1 and the sliding seat 3.
