Description

Technical Field

[0001] This utility model relates to the technical field of metal processing, and in particular to a clamping device for plasma cutting. Background Technology

[0002] Plasma cutting is a technology that uses a high-temperature plasma arc to cut metal materials. It is widely used in metal processing, equipment manufacturing and other processes.

[0003] Existing plasma cutting machines require operators to hand-hold the plasma gun and move it along the metal sheet to cut it into a circular shape. Due to the instability of the operator's hand, the cutting head is prone to wobbling, resulting in large dimensional errors in the cut circular metal sheets. This necessitates extensive grinding before use. This method of cutting circular metal sheets produces sheets with significant dimensional errors and requires substantial post-cutting grinding work.

[0004] In the process of implementing this embodiment, the inventors discovered at least the following problems: The circular metal sheets cut by the workers using a handheld plasma gun have large dimensional errors, requiring a significant amount of grinding work later. Utility Model Content

[0005] The purpose of this utility model is to provide a clamping device for plasma cutting, which solves the technical problem that the circular metal plates cut by operators using handheld plasma guns have large dimensional errors and require a large amount of grinding work in the later stage.

[0006] Utility model solution: This utility model provides a clamping device for plasma cutting, including a fixed base, a column, a crossbeam, a radius rod, a connecting frame, and a clamping component; the column is detachably inserted into the fixed base; one end of the crossbeam is sleeved on the column; the radius rod is located below the crossbeam and is pivotally connected to the other end of the crossbeam; the connecting frame is slidably connected to the radius rod; the clamping component includes an upper connecting plate, a connecting column, a lower limiting frame, and several first bolts; the upper connecting plate is pivotally connected to the lower part of the connecting frame, one end of the connecting column is connected to the upper connecting plate, and the other end is connected to the lower limiting frame, and the first bolts are threadedly connected to the lower limiting frame.

[0007] Furthermore, the bottom of the fixing base is triangular.

[0008] Furthermore, the column is provided with a sliding groove and several threaded holes; one end of the crossbeam is provided with a protrusion adapted to the sliding groove, and it is detachably connected with a second bolt, which is adapted to the threaded holes.

[0009] Furthermore, the crossbeam is connected to a support rod, and the column is provided with a limiting groove; one end of the support rod is slidably connected to the limiting groove; the column, the crossbeam, and the support rod form a triangular support.

[0010] Furthermore, the connecting frame is threaded with a third bolt, which abuts against the crossbeam.

[0011] Beneficial effects: This invention provides a clamping device for plasma cutting. In use, the plasma gun is inserted into the lower limit frame, and the first bolt is tightened to clamp the plasma gun onto the lower limit frame. Then, the position of the connecting frame on the radius rod is adjusted to determine the radius of the circular metal sheet to be cut. The plasma cutting machine is started, and the operator rotates the plasma gun, causing the clamping device and the radius rod to rotate, ensuring a good quality circular metal sheet cut. During the cutting process, the clamping device assists the operator in stabilizing the plasma gun, reducing hand instability. This type of clamping device for plasma cutting has a relatively large dimensional error, and requires less post-cutting grinding. Attached Figure Description

[0020] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0021] This embodiment provides a clamping device for plasma cutting. Please refer to [link / reference]. Figure 1-3 As shown, the device includes a fixed base 100, a column 200, a crossbeam 300, a radius rod 400, a connecting frame 500, and a clamping member 600. The column 200 is detachably inserted into the fixed base 100. One end of the crossbeam 300 is sleeved on the column 200. The radius rod 400 is located below the crossbeam 300 and is pivotally connected to the other end of the crossbeam 300. The connecting frame 500 is slidably connected to the radius rod 400. The clamping member 600 includes an upper connecting plate 610, a connecting column 620, a lower limiting frame 630, and several first bolts 640. The upper connecting plate 610 is pivotally connected to the lower part of the connecting frame 500. One end of the connecting column 620 is connected to the upper connecting plate 610, and the other end is connected to the lower limiting frame 630. The first bolts 640 are threadedly connected to the lower limiting frame 630.

[0022] Specifically, the column 200 is rectangular, and the fixing base 100 is used to limit the four sides of the column 200 to ensure the stability of the column 200. The column 200 is used to support the crossbeam 300 and prevent the crossbeam 300 from tilting. The radius rod 400 is used to set the rotation radius of the clamping member 600. The connecting frame 500 is used to connect the radius rod 400 and the clamping member 600 and to adjust the position of the clamping member 600 below the radius rod 400. The upper connecting plate 610 is pivotally connected to the connecting frame 500, so that the clamping member 600 can rotate relative to the connecting frame 500. There are two connecting columns 620, which are used to connect the upper connecting plate 610 and the lower limiting frame 630 together. The lower limiting frame 630 is used to limit the plasma gun. There are three first bolts 640, which limit the plasma gun in three positions within the lower limiting frame 630. When in use, insert the plasma gun into the lower limit frame 630 and tighten the first bolt 640 to press the plasma gun firmly onto the lower limit frame 630. Then, adjust the position of the connecting frame 500 on the radius rod 400 to determine the radius of the circular metal plate to be cut. Start the plasma cutting machine, and the operator rotates the plasma gun, the clamping part 600 rotates, and the radius rod 400 rotates to ensure that the quality of the cut circular metal plate is good. During the cutting process, the clamping part 600 assists the operator in stabilizing the control of the plasma gun and reducing the instability of the operator's hands.

[0023] In this embodiment, the bottom of the fixing base 100 is triangular.

[0024] Specifically, the triangle shape provides greater stability, preventing the column from wobbling and affecting cutting accuracy.

[0025] In this embodiment, the column 200 is provided with a sliding groove 210 and a plurality of threaded holes 220; one end of the crossbeam 300 is provided with a protrusion 310 adapted to the sliding groove 210, and is detachably connected with a second bolt 320, which is adapted to the threaded holes 220.

[0026] Specifically, the groove 210 and the protrusion 310 enhance the contact surface between the support column 200 and the crossbeam 300, thereby making the positioning of the support column 200 on the crossbeam 300 more stable; the crossbeam 300 can slide on the support column 200, and the distance of the crossbeam 300 on the support column 200 can be limited by the second bolt 320 and the threaded hole 220, thereby facilitating the adjustment of the height of the crossbeam 300.

[0027] In this embodiment, the crossbeam 300 is connected to the support rod 330, and the column 200 is provided with the limiting groove 230; one end of the support rod 330 is slidably connected to the limiting groove 230; the column 200, the crossbeam 300 and the support rod 330 form a triangular support.

[0028] Specifically, one end of the support rod 330 is inserted into the limiting groove 230 to limit the position of the support rod 330; the column 200, the crossbeam 300 and the support rod 330 form a triangular support, which enhances the stability of the crossbeam 300 and thus ensures the cutting accuracy of the plasma gun.

[0029] In this embodiment, the connecting frame 500 is threadedly connected to a third bolt 510, which abuts against the crossbeam 300.

[0030] Specifically, by tightening the third bolt 510, the connecting frame 500 is prevented from moving on the crossbeam 300.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
