[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The limiting structure of the plasma cutting machine is provided with a machine body, a moving mechanism, a rotating mechanism, a rotating rod, a telescopic plate and a pulley, and the electric push rod is started. The electric push rod pushes the support plate, the connecting block and the two support frames to move synchronously, so that the two rotating rods rotate toward each other, thereby making the two moving clamping plates move relative to each other, thereby driving the two support frames and the connecting block on the other side to move toward each other, so that the device can automatically limit workpieces of various specifications and sizes, avoiding the mismatch of the device due to different specifications and sizes of the processed workpieces, and improving the use range of the device.

[0014] 3. The plasma cutting machine uses a limiting structure. By setting a slide rail, a support seat, an electric push rod, a telescopic rod, a support plate and a support frame, the support seat can be adjusted first so that the support seat can drive the electric push rod, the telescopic rod, the support plate and the support frame to move synchronously, and then the workpiece to be processed is placed on the telescopic plate, so that the device can automatically adjust the position of the support plate and the support frame, which is convenient for the placement of the workpiece and effectively improves the practicability of the device.

DETAILED DESCRIPTION

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: a limiting structure for a plasma cutting machine, comprising a body 1, both sides of the body 1 are connected with support rods 2, and the support rods 2 are provided, and the support rods 2 can support the slide rail 301, so as to prevent the slide rail 301 from shaking due to the influence of the movement of the support seat 302, thereby ensuring the stable use of the slide rail 301;

[0022] The support rod 2 is in an L-shape, and two rotating rods 6 are hinged with a same moving card plate 7 through a pin shaft, one end of the moving card plate 7 is connected to a telescopic plate 8, and a pulley 9 is connected to the telescopic plate 8. The support rod 2 is connected to a moving mechanism 3, and the moving mechanism 3 includes a slide rail 301. By setting the slide rail 301, the slide rail 301 and the support seat 302 cooperate with each other, which can avoid the support seat 302 from being offset and misaligned when moving, thereby ensuring the stable movement of the support seat 302;

[0023] There are two slide rails 301, which are connected to the support rod 2. The two slide rails 301 are slidably connected with support seats 302. By providing the support seats 302, the support seats 302 can support the electric push rod 303, so as to avoid the electric push rod 303 from deviating and falling when moving, thereby ensuring the stable movement of the electric push rod 303.

[0024] An electric push rod 303 is connected to the side of the support seat 302 on the right side, and a telescopic rod 304 is connected to the side of the support seat 302 on the right side. The electric push rod 303 and the telescopic rod 304 are connected to a support plate 305 at one end close to each other. Two support frames 306 are connected to both sides of the support plate 305. A rotating mechanism 4 is connected to one of the support frames 306. The rotating mechanism 4 includes a motor 401, and the motor 401 is connected to the support frame 306. By setting the support frame 306, the support frame 306 can support the motor 401 to avoid the motor 401 from deviating and falling when moving, thereby ensuring the stable movement of the motor 401.

[0025] The bottom end of the motor 401 is connected to a first rotating shaft 402, and two driving wheels 403 are externally connected to the first rotating shaft 402. The first rotating shaft 402 is rotatably connected to the corresponding support frame 306. The other three support frames 306 are hinged to two limiting wheels 404 through three pins. By setting the limiting wheels 404, and the limiting wheels 404 and the driving wheels 403 cooperate with each other, the main machine can automatically load the workpiece, thereby improving the speed of loading the workpiece. A connecting block 5 is connected to one side of the support frame 306, and the connecting block 5 is hinged to a rotating rod 6 through a pin.

[0026] The working principle of the utility model is:

[0027] When using the device, the workpiece to be processed is placed on the telescopic plate 8, and then the electric push rod 303 is started. The electric push rod 303 pushes the support plate 305, the connecting block 5 and the two support frames 306 to move synchronously, so that the two rotating rods 6 rotate toward each other, thereby causing the two movable clamping plates 7 to move relative to each other, and stretching the telescopic plate 8, thereby driving the two support frames 306 and the connecting block 5 on the other side to move toward each other, and making the telescopic rod 304 in a stretched state until the limiting wheel 404 and the driving wheel 403 can fit and limit the workpiece to be processed, and then start the motor 401. When the motor 401 drives the first rotating shaft 402 and the driving wheel 403 to rotate, it can drive the workpiece to move on the pulley 9, so that the workpiece can be automatically loaded.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0029] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
