Description

Technical Field

[0001] This utility model relates to the field of chamfering fixture technology, and in particular to a fixture for chamfering square tubes. Background Technology

[0002] Square and rectangular tubes are a type of steel pipe, referring to steel pipes with equal or unequal side lengths. They are made from strip steel through a process of rolling. Generally, the strip steel is unpacked, flattened, rolled, and welded into a round tube, which is then rolled into a square tube and cut to the required length.

[0003] Currently, when producing square tubes, it is necessary to chamfer the ends to facilitate subsequent assembly into a frame. However, the existing chamfering process requires manual marking each time a cut is made, which is cumbersome. In addition, manual marking can introduce errors, affecting the processing accuracy. Utility Model Content

[0004] To address the problems in existing technologies, this utility model provides a fixture for chamfering square tubes. The basic concept of this utility model's technical solution is as follows:

[0005] A fixture for chamfering square tubes includes a processing table. An angle positioning component is provided on the top of the processing table near both sides. A transmission cavity is opened in the middle of the top of the processing table. A rotating block is rotatably arranged inside the transmission cavity. The top of the rotating block extends to the top of the processing table. An adjustment turntable is fixed on the top of the rotating block. The bottom of the adjustment turntable is in contact with the top of the processing table.

[0006] Optionally, the angle positioning component includes an arc-shaped positioning plate and an arc-shaped guide rail. The arc-shaped positioning plate is fixed to the top of the processing table near one side edge, and the top of the arc-shaped positioning plate has multiple positioning holes at equal intervals.

[0007] Optionally, the arc-shaped guide rail is fixed to the top of the processing table, and the arc-shaped guide rail is located between the adjusting turntable and the arc-shaped positioning plate on opposite sides.

[0008] Optionally, a slide block is slidably engaged on the outer surface of the arc-shaped guide rail, and guide blocks are fixed on both sides of the inner wall of the slide block near the bottom.

[0009] Optionally, the two guide blocks are slidably engaged on the outer surface of the arc-shaped guide rail, and a side plate is fixed on one side of the slide block, with positioning bolts provided on the side plate.

[0010] Optionally, the bottom of the positioning bolt extends through to the bottom and into the interior of the positioning hole, and a U-shaped clamp is fixed to the other side of the slide.

[0011] Optionally, a clamping bolt is provided at the top of the U-shaped clamp, and a pressing plate is provided inside the U-shaped clamp. The bottom of the clamping bolt extends through the interior of the U-shaped clamp and is fixed to the pressing plate.

[0012] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0013] 1. In this utility model, when it is necessary to perform inclined cutting on the square tube, first place the square tube on the adjusting turntable, then clamp both sides of the square tube into the inside of the U-shaped clamping plate, and at the same time rotate the clamping bolt so that the pressing plate can be driven to press the square tube tightly. At this time, the relative angle between the square tube and the processing table can be changed by sliding the slide on the arc guide rail, so that it can be adjusted to a suitable angle for inclined cutting, which is convenient for people to process and operate.

[0014] 2. In this utility model, when adjusting the angle of the square tube, the mutual limiting of the positioning bolt and the positioning hole makes it easy for people to adjust the square tube to a suitable angle and then position the slide block to prevent it from shaking during cutting. The positioning hole is opened on the arc-shaped positioning plate, and the arc-shaped positioning plate is set in an arc shape, which helps people to mark the angle scale line and make it easy for people to quickly locate the suitable angle.

A transmission cavity 12 is provided in the middle of the top of the processing table 1, and a rotating block 13 is rotatably arranged inside the transmission cavity 12. The top of the rotating block 13 extends to the top of the processing table 1, and an adjusting turntable 2 is fixed on the top of the rotating block 13. The bottom of the adjusting turntable 2 is in contact with the top of the processing table 1.

[0025] The effect achieved by the entire embodiment 1 is that when it is necessary to perform inclined cutting on the square tube, the square tube is first placed on the adjusting turntable 2, and then the two sides of the square tube are respectively clamped into the interior of the U-shaped clamping plate 9. At the same time, the clamping bolt 10 is rotated so that the pressing plate 11 can be driven to press the square tube tightly. At this time, the relative angle between the square tube and the processing table 1 can be changed by sliding the slide block 5 on the arc guide rail 4, so that it can be adjusted to a suitable angle for inclined cutting, which is convenient for people to process and operate.

[0026] Example 2, as Figure 1-4 As shown, the angle positioning component includes an arc-shaped positioning plate 3 and an arc-shaped guide rail 4. The arc-shaped positioning plate 3 is fixed to the top of the processing table 1 near one edge. Multiple positioning holes 6 are equidistantly opened on the top of the arc-shaped positioning plate 3. The arc-shaped guide rail 4 is fixed to the top of the processing table 1 and is located between the adjusting turntable 2 and the opposite side of the arc-shaped positioning plate 3. A slide block 5 is slidably engaged on the outer surface of the arc-shaped guide rail 4. Guide blocks 14 are fixed on the inner walls of both sides of the slide block 5 near the bottom. The two guide blocks 14 are slidably engaged on the outer surface of the arc-shaped guide rail 4. A side plate 7 is fixed on one side of the slide block 5.

A U-shaped clamping plate 9 is fixed on the other side of the slide block 5. A clamping bolt 10 is provided on the top of the U-shaped clamping plate 9. A pressing plate 11 is provided inside the U-shaped clamping plate 9. The bottom of the clamping bolt 10 extends through to the interior of the U-shaped clamping plate 9 and is fixed on the pressing plate 11.

[0027] The effect achieved by the entire embodiment 2 is that, when adjusting the angle of the square tube, the mutual limiting of the positioning bolt 8 and the positioning hole 6 makes it easy for people to adjust the square tube to a suitable angle and then position the slide block 5, preventing it from shaking during cutting. The positioning hole 6 is opened on the arc-shaped positioning plate 3, and the arc-shaped positioning plate 3 is set in an arc shape, which helps people to mark the angle scale lines and makes it easy for people to quickly locate the suitable angle.

[0028] Working principle: When it is necessary to perform inclined cutting on the square tube, first place the square tube on the adjusting turntable 2, then clamp both sides of the square tube into the U-shaped clamping plate 9, and at the same time rotate the clamping bolt 10 so that the pressing plate 11 can be driven to press the square tube tightly. At this time, the relative angle between the square tube and the processing table 1 can be changed by sliding the slide block 5 on the arc guide rail 4, so that it can be adjusted to a suitable angle for inclined cutting, which is convenient for processing operations. When adjusting the angle of the square tube, the mutual limiting of the positioning bolt 8 and the positioning hole 6 makes it easy for people to adjust the square tube to a suitable angle and position the slide block 5 to prevent it from shaking during cutting.
