This way of fixing the square tube causes interference when processing the end of the square tube or opening a through groove along the length direction on the side wall of the square tube. Therefore, there is room for improvement. Summary of the Utility Model

[0003] In order to improve the problem of interference caused when processing the end of the square tube or opening a through groove along the length direction on the side wall of the square tube when fixing the square tube, the present application provides a fixing tooling for square tube processing.

The clamping component and the processing table are connected by a magnetic attraction component. At least one group of clamping components is arranged on the processing table. A moving part and a fixing part are arranged on the clamping component. The distance formed by the moving part and the fixing part is used to clamp square tubes with different widths and at different positions.

[0006] By adopting the above technical solutions, the clamping component is manually installed on the processing table, and cooperates with the milling machine to process the square tube. The two sides of the square tube are clamped by the clamping component, improving the stability of the square tube during the processing. One end of the clamping component serves as the fixing part for limiting and fixing, and the other end serves as the movable part. During the movement, the distance between the fixing part and the moving part is adjusted, so as to facilitate the clamping of square tubes with different diameters. Since only one end needs to be clamped, the square tube can be clamped and fixed at any position, reducing the interference effect on different positions of the square tube during processing.

[0007] Optionally, the moving part includes a base, a clamping plate slidably connected to the base, and a driving rod rotatably connected to the base. The driving rod is threadedly connected to the clamping plate. The clamping plate slides along the axis of the driving rod. A driving member for driving rotation is further installed at one end of the driving rod away from the clamping plate.

[0008] By adopting the above technical solutions, the driving member drives the driving rod to rotate, and the driving rod drives the clamping plate to move along the axis of the driving rod, realizing the mutual approach or separation of the clamping plate and the fixing part, and further clamping or releasing the square tube.

[0009] Optionally, the driving member is an adjusting handwheel or a servo motor.

[0010] By adopting the above technical solution, the square tube is clamped by the adjusting handwheel to ensure stable clamping of the square tube; the servo motor controls the drive to improve the clamping force and accuracy.

[0011] Optionally, the fixing portion has a fixing plate parallel to the end face of the clamping plate, and the fixing plate and the base are integrally formed.

The first magnet plate is embedded in the processing table, the second magnet plate is embedded in the base, and the first magnet plate and the second magnet plate are magnetically attracted and matched.

[0014] By adopting the above technical solution, the opposite end faces of the first magnet plate and the second magnet plate have opposite magnetic polarities, and the magnetically attracted and matched manner facilitates the staff to place the base and the processing table in different positions according to needs.

[0015] Optionally, a positioning pin is further installed on the base, a pin hole is formed on the processing table, the positioning pin and the pin hole have the same shape and specifications, and the positioning pin and the pin hole are inserted and matched.

[0016] By adopting the above technical solution, the positioning pin and the base are integrally welded and formed, corresponding to the positions of the pin holes formed on the processing table one by one, improving the installation stability between the base and the processing table.

[0017] Optionally, the base is provided with a moving channel for the drive rod to drive, which is used for depositing the dropped debris.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The following will further elaborate on the present application Figure 1 in conjunction with the attached Figure 4 drawings for a more detailed description.

[0030] The embodiments of the present application disclose a fixing tooling for square tube processing.

[0031] Refer to Figure 1, which is composed of a processing table 1, a clamping component 2 and a milling machine 3. The processing table 1 is fixedly installed on the milling machine 3, and the clamping component 2 and the processing table 1 are connected by a magnetic attraction component 4. At least one set of clamping components 2 is arranged on the processing table 1. In the embodiment, three sets of clamping components 2 are used to clamp different positions of square tubes with different lengths. A moving part 21 and a fixing part 22 are arranged on the clamping component 2. The distance formed by the moving part 21 and the fixing part 22 is used to clamp square tubes with different widths and different positions. The clamping component 2 is manually installed on the processing table 1 and cooperates with the milling machine 3 to process the square tube. The clamping component 2 clamps both sides of the square tube, improving the stability of the square tube during processing. One end of the clamping component 2 serves as the fixing part 22 for limiting and fixing, and the other end serves as the movable part. The distance between the fixing part 22 and the moving part 21 is adjusted during the moving process, so as to facilitate the clamping of the diameters of square tubes of different sizes. Since only one end is used for clamping, the square tube can be clamped and fixed at any position, reducing the interference effect of processing at different positions of the square tube.

[0032] See Figure 4 As shown, the moving part 21 includes a base 211, a clamping plate 212 slidably connected to the base 211, and a driving rod 213 rotatably mounted on the base 211. The driving rod 213 is a threaded rod, and the driving rod 213 is threadedly connected to the clamping plate 212. The clamping plate 212 slides along the axis direction of the driving rod 213. A driving member for driving rotation is further installed at one end of the driving rod 213 away from the clamping plate 212.

[0033] The driving member drives the driving rod 213 to rotate, and the driving rod 213 drives the clamping plate 212 to move along the axis of the driving rod 213, realizing the clamping plate 212 and the fixing part 22 approaching or separating from each other, and further clamping or loosening the square tube. The driving member is an adjusting handwheel or a servo motor. Both the adjusting handwheel and the servo motor are conventional existing technologies, and neither the adjusting handwheel nor the servo motor is shown in the drawings. In this embodiment, when the adjusting handwheel is used as the driving source, it is convenient for manual adjustment to clamp the square tube and ensure the stable clamping of the square tube; in the embodiment, when the servo motor is used as the driving source to control the transmission of the driving rod 213, it helps to improve the clamping force and accuracy.

[0034] See Figure 4 As shown, the fixing part 22 has a fixing plate 221 parallel to the end face of the clamping plate 212. The fixing plate 221 and the base 211 are integrally formed. The fixing plate 221 is in a regular rectangle, and its material is cast iron material: HT200 - 300 or the material is high-strength cast iron HT20 - 40, and the working surface hardness is HB770 - 240. The fixing plate 221 and the clamping plate 212 are parallel to each other, and during clamping, it can better fit the side wall of the part to be processed, maintaining the stability of the square tube clamping.

[0035] See Figure 2As shown, the magnetic attraction component 4 is composed of a first magnet plate 41 and a second magnet plate 42. The first magnetic plate and the second magnetic plate attract each other. The first magnet plate 41 is embedded in the processing table 1, and the second magnet plate 42 is embedded in the interior of the base 211. When the base 211 is placed on the processing table 1, the first magnet plate 41 and the second magnet plate 42 are magnetically attracted and matched, so that the processing table 1 and the base 211 are kept stable. The magnetic attraction and matching method facilitates the staff to place the base 211 and the processing table 1 at different positions according to needs.

[0036] See Figure 3 As shown, four positioning pins 5 are integrally formed and welded at the bottom of the base 211. Four pin holes 6 are provided on the processing table 1. The positioning pins 5 and the pin holes 6 have the same shape and specifications. The positioning pins 5 and the pin holes 6 are inserted and matched, and are in one-to-one correspondence with the positions of the pin holes 6 provided on the processing table 1, thereby improving the installation stability between the base 211 and the processing table 1.

[0037] An activity channel driven by the driving rod 213 is provided on the base 211 for depositing fallen debris. The provided activity channel can observe the driving situation of the driving rod 213 on the base 211. At the same time, the clamping plate 212 moves along the axis of the driving rod 213. There is a certain height difference between the driving rod 213 and the bottom of the base 211 and the activity channel. Therefore, the debris generated during the processing of the square tube directly falls to the inner wall of the activity channel, reducing the occurrence of side wear on the side wall of the square tube clamped by the debris.

[0038] The implementation principle of a fixing tooling for square tube processing in an embodiment of the present application is as follows: The clamping component 2 is placed on the processing table 1. The first magnet plate 41 on the processing table 1 and the second magnet plate 42 on the base 211 are magnetically attracted to each other, so that it is convenient for the staff to magnetically fix the base 211 at different positions on the processing table 1 according to needs, thereby better clamping and fixing the square tube and reducing the interference to the processed square tube; The driving rod 213 is driven to rotate by the driving member, and the driving rod 213 drives the clamping plate 212 to approach the fixing plate 221 side, realizing the clamping effect on square tubes with different diameters.
