[0018] This invention addresses the problems existing in the above-mentioned technical solutions by proposing a pioneering technical solution: A fixing structure is provided on the base to secure its bottom to the workpiece. An obstacle clearance groove corresponding to the cutting machine's guide movement trajectory is provided at the cutting position of the base, directly opposite the cutting machine. The cutting machine can pass through the obstacle clearance groove on the base to cut the workpiece placed at the bottom of the base; alternatively, the cutting position of the cutting machine is located outside the base throughout its entire guide movement trajectory, allowing the cutting machine to cut the workpiece placed at the bottom of the base from the outside of the base. In this invention, the base of the cutting machine bracket is fixed to the workpiece, and the size of the workpiece is not limited. Large workpieces can then be cut by utilizing the cutting groove or the position setting of the cutting machine.

[0019] Based on the above technical concept, the present invention provides a cutting machine support as follows: Figure 1 The rectangular base 1 shown has a movable base 3 on it, which is guided to move. The movable base 3 has a mounting bracket for a cutting machine (i.e., as shown in the image). Figure 1 The angle grinder 8 shown has a mounting bracket with a base 1 that secures its bottom to a workpiece. The base 1 has a clearance groove corresponding to the cutting machine's guide path at the cutting position. The cutting machine can pass through this groove to cut the workpiece placed at the bottom of the base 1. The upper part of the base 1 has numerous parts; if a workpiece is placed on top of the base 1, its placement area is limited by these parts, thus restricting its size. In this invention, the base 1 of the cutting machine bracket is fixed to the workpiece, eliminating size limitations. Large workpieces can then be cut using the clearance groove or the cutting machine's position setting.

[0020] In this embodiment, the fixing structure is an adsorption structure. The adsorption structure ensures both reliable fixing of the base and the workpiece and convenient fixing of both. Alternatively, in other embodiments, the fixing structure may be a screw and a clamping plate installed on the edge of the base. The nut end of the screw is located at the lower part of the base, and a clamping plate is fitted onto the screw, corresponding to the nut end and the workpiece. Tightening the screw allows the workpiece to be clamped between the clamping plate and the workpiece.

[0021] In a preferred embodiment, the adsorption structure is a magnet 7. In this embodiment, the magnet 7 is a powerful magnet, which ensures the reliability of the fixation between the base 1 and the workpiece. Furthermore, in other embodiments, the adsorption structure can also be a negative pressure suction cup installed at the bottom of the base 1, thereby fixing the base and the workpiece together.

[0022] In this embodiment, a scale 13 is provided on the base 1 along the cutting motion trajectory of the cutting machine. This facilitates control of the cutting length of the cutting machine to accurately complete the cutting of the workpiece.

[0023] In the embodiment, the base 1 is provided with guide rods 5 arranged in parallel to the base 1, and the moving seat 3 is provided with bearings 4 capable of slidingly cooperating with the guide rods 5. The bearings 4 and the guide rods 5 are cooperated to realize the guided movement of the moving seat 3, thereby driving the guided movement of the angle grinder 8 mounted on the moving seat 3. The cooperation of the bearings 4 and the guide rods 5 ensures the stability of the guided movement of the moving seat 3 and the stability of the guided cutting of the angle grinder 8. In addition, in other embodiments, corresponding guide rails can be provided on the base, and sliding blocks capable of cooperatively guiding the guide rails can be provided on the bottom of the moving seat. The sliding blocks on the moving seat and the guide rails on the base are cooperated to realize the guided movement of the moving seat.

[0024] In the embodiment, the guide rods 5 are arranged in pairs, and the mounting bracket is located between the pair of guide rods 5. In the embodiment as shown in Figure 1 In the embodiment, the bearings 4 are four in total and arranged in two rows. The two rows of bearings 4 are arranged on the two sides of the mounting bracket to cooperatively guide the two guide rods 5. The mounting bracket arranged between the two guide rods 5 is relatively stable during operation and is not easy to be offset, thereby ensuring the stability of the cutting machine during cutting. It is easily conceivable that in another embodiment, only one guide rod can be provided, which is located on one side of the mounting bracket. In this case, a roller can be provided on the bottom of the other side of the moving seat to ensure the stability of the guided movement of the moving seat.

[0025] In the embodiment, the moving seat 3 is plate-shaped and arranged close to the upper side of the base 1, and the bearings 4 are mounted on the upper portion of the moving seat 3. The moving seat 3 of the embodiment is suspended on the base 1. After the bearings 4 mounted on the upper portion of the plate-shaped moving seat 3 are cooperated with the guide rods 5, the linear distance between the cutting machine mounted on the moving seat 3 and the base 1 is relatively small, thereby reducing the adjustment range of the cutting machine during cutting. In addition, in another embodiment, the bearings can also be mounted on the lower portion of the moving seat. In other embodiments, the moving seat can also be in the form of a door frame, including two vertical support columns and a horizontal plate located on the top of the vertical support columns. The mounting bracket is mounted on the horizontal plate. In this case, the bearings can also be mounted on the vertical support columns.

[0026] In the embodiment, the mounting bracket is a luffing arm 6 rotatably mounted on the moving base 3 about a horizontal axis perpendicular to the guiding moving track. The luffing arm 6 is configured to adjust the height of the cutting machine and thus the cutting depth of the cutting machine. The luffing arm 6 is further provided with a handle 10 at the end away from the moving base 3. In this way, the operator can hold the handle 10 to facilitate the subsequent cutting work. In another embodiment, the moving base can also be in the form of a door frame, including two vertically extending support columns and a cross beam connecting the two support columns. The bottom of the two support columns is guided by the base, and the mounting bracket is movably mounted on the support columns in the up-down direction. The cross beam is provided with an adjusting screw, the lower end of the adjusting screw is connected with the mounting bracket, and the adjusting screw can drive the mounting bracket to move up and down when it is rotated. The cutting machine is mounted on the mounting bracket to adjust the height of the cutting machine.

[0027] In the embodiment, the luffing arm 6 is provided with a mounting plate 12 for mounting the U-shaped bolt 11 on the side away from the base 1. The luffing arm 6 presses the handle of the cutting machine against the luffing arm 6 through the U-shaped bolt 11. The U-shaped bolt 11 is adapted to the columnar handle of the cutting machine on one hand, and ensures the reliability of the mounting of the cutting machine and the luffing arm 6 on the other hand. In other embodiments, the luffing arm 6 can also be mounted with the cutting machine through a hoop, as long as the reliability of the mounting is ensured.

[0028] In the embodiment, the mounting plate 12 for mounting the U-shaped bolt 11 is located at the end of the luffing arm 6 away from the moving base 3, so that after the cutting machine is mounted on the luffing arm 6, the cutting wheel body is located between the U-shaped bolt 11 and the rotation axis of the luffing arm 6. The handle of the cutting machine has a certain length, and in the embodiment, the mounting plate 12 is provided with two mounting plates to ensure the reliability of the mounting of the cutting machine. After the cutting machine is mounted, the cutting wheel body is located at the end of the luffing arm 6 close to the moving base 3. Compared with the case where the cutting wheel body is located at the end of the luffing arm 6 close to the handle 10, the cutting machine bracket of the embodiment can realize the contact between the cutting wheel body and the workpiece by pressing a smaller amplitude during cutting on one hand, and can also realize the safety of operation on the other hand.

[0029] In the second embodiment of the utility model, the cutting position of the cutting machine on the whole guiding moving track of the cutting machine is located outside the base, and the cutting machine can cut the workpiece placed on the bottom of the base outside the base. In this embodiment, the moving base also realizes guiding movement through the cooperation of the bearing and the guide rod. Specifically, the side edge of the moving base is close to the length direction edge of the base, and the mounting bracket provided on the moving base is also close to the side edge of the moving base, so that the cutting position of the cutting machine on the whole guiding moving track of the cutting machine mounted on the mounting bracket is located outside the base, and the guide rods are arranged in pairs and are arranged on the side of the moving base away from the mounting bracket.

[0030] The above merely describes preferred embodiments of the present application and is not intended to limit the present application. The patent protection scope of the present application is defined by the claims, and any equivalent structural changes made according to the content of the specification and drawings of the present application should also be included in the protection scope of the present application.
