[0023] The following is a detailed description of the preferred embodiments of the present utility model in conjunction with the drawings.

[0024] See also Figures 1 to 4 The utility model provides a plasma cutting and polishing integrated processing equipment, including: a robot 1, a plasma spray gun 2, a polishing machine 3, a fixture assembly and a workpiece positioning device.

[0025] Among them, the robot 1 is fixedly installed on the robot base 15 and is located on one side of the workpiece positioning device. The plasma spray gun 2 and the polishing machine 3 are both installed on the robot 1 through a clamp assembly, and the angles of the plasma spray gun 2 and the polishing machine 3 can be adjusted by operating the clamp assembly to meet respective processing requirements and improve flexibility.

[0026] The workpiece positioning device includes a frame 4 and a positioning fixture 5 mounted on the top of the frame 4. The positioning fixture 5 is used to place and position the workpiece 6 to be processed to ensure that the workpiece 6 will not shift during the processing.

[0027] In this embodiment, the workpiece 6 is formed by die casting. When the workpiece 6 is formed, an integrated material handle is formed. The utility model uses the plasma spray gun 2 to cut off the material handle on the workpiece 6 .

[0028] The robot 1 is used to drive the plasma spray gun 2 to move to the cutting station to perform plasma cutting on the workpiece 6 on the positioning fixture 5, and the robot 1 is also used to drive the polishing machine 3 to move to the polishing station to grind and polish the workpiece 6 on the positioning fixture 5. The part of the workpiece 6 to be grinded and polished can be either the cutting part or other parts of the workpiece 6 where burrs exist.

[0029] In this embodiment, the robot 1 is a six-axis industrial robot.

[0030] In addition, a scrap cart 7 is provided below the positioning jig 5 , and the scrap cart 7 is used to receive the scrap dropped during cutting and grinding. When the scrap cart 7 is fully loaded with scrap, the scrap cart 7 can be transported out manually or by a driving device.

[0031] In this utility model, a plasma spray gun 2 and a polishing machine 3 are simultaneously assembled on a robot 1. A positioning jig 5 is relied on to place and position a workpiece 6 to be processed, ensuring that the workpiece 6 does not shift during the processing. The robot 1 first drives the plasma spray gun 2 to move to the cutting station to perform plasma cutting on the workpiece 6 positioned on the positioning jig 5 to remove the stock handle on the workpiece 6. During this cutting process, the polishing machine 3 will also be driven by the robot 1 to displace, but it is in a standby state. After the cutting is completed, the robot 1 then drives the polishing machine 3 to move to the polishing station to polish the parts of the workpiece 6 on the positioning jig 5 that need to be polished. During this polishing process, similarly, the plasma spray gun 2 will be driven by the robot 1 to displace, but it is in a standby state. And the waste materials generated by cutting and polishing will freely fall into a waste material cart 7, facilitating the disposal of waste materials. The integrated processing equipment for plasma cutting and polishing in this utility model integrates the plasma cutting and polishing processes to achieve continuous operation of cutting and polishing, so as to improve the processing efficiency, ensure the processing quality, improve the consistency of workpiece processing, and reduce the labor intensity.

[0032] It should be noted that the plasma spray gun 2 and the polishing machine 3 in this utility model both adopt existing conventional technologies, and their specific structures will not be elaborated herein.

[0033] Furthermore, in order to guide the waste materials to fall into the waste material cart 7 and prevent the waste materials from spilling outwards, a waste material funnel 12 is also installed on the top of the machine frame 4 in this utility model. The positioning jig 5 is located directly above the waste material funnel 12, and the material dropping port of the waste material funnel 12 is arranged directly opposite to the waste material cart 7 below. The waste materials generated by cutting and polishing will freely fall into the waste material cart 7 along the waste material funnel 12.

[0034] As Figure 1 shown, the integrated processing equipment for plasma cutting and polishing in this utility model further includes a protective fence 13. The protective fence 13 surrounds the robot 1 and the workpiece positioning device, and there is a loading and unloading window on the protective fence 13 facing the workpiece positioning device to facilitate manual loading and unloading on the positioning jig 5. In addition, a safety light curtain 14 is installed on the loading and unloading window. It is a safety sensor, and its main function is to detect whether an object passes through the area of the loading and unloading window to ensure that personnel will not enter the dangerous area during the operation of the equipment, thereby ensuring the safety of the workplace.

[0035] Refer to Figure 2 and Figure 3, the fixture assembly includes a flange joint 8, a connecting rod 9, a first fixing block 10 and a second fixing block 11. One end of the flange joint 8 is a flange plate, and the other end is a cylinder. The flange joint 8 is fixedly connected to the robot 1 through the flange plate. The connecting rod 9 is vertically fixed on the cylinder of the flange joint 8. The plasma spray gun 2 is fixed to one end of the connecting rod 9 through the first fixing block 10, and the polishing machine 3 is fixed to the other end of the connecting rod 9 through the second fixing block 11. Moreover, the plasma spray gun 2 and the polishing machine 3 are respectively on both sides of the flange joint 8 to avoid interference between the two during processing.

[0036] Refer to Figure 3 , both ends of the first fixing block 10 are provided with first shaft clamping parts 1001, and the center lines of the shaft holes of the two first shaft clamping parts 1001 are vertically distributed. One of the first shaft clamping parts 1001 is locked on the connecting rod 9 through a first bolt, and the other first shaft clamping part 1001 clamps the plasma spray gun 2 through a second bolt. By loosening the first bolt, the first fixing block 10 rotates around the connecting rod 9 to adjust the pitching angle of the plasma spray gun 2; similarly, by loosening the second bolt, the height of the plasma spray gun 2 can be adjusted.

[0037] The second fixing block 11 is Z-shaped, and both ends are provided with second shaft clamping parts 1101. The center lines of the shaft holes of the two second shaft clamping parts 1101 are vertically distributed. One of the second shaft clamping parts 1101 is locked on the connecting rod 9 through a third bolt, and the other second shaft clamping part 1101 clamps the polishing machine 3 through a fourth bolt. By loosening the third bolt, the second fixing block 11 rotates around the connecting rod 9 to adjust the pitching angle of the polishing machine 3; similarly, by loosening the fourth bolt, the polishing machine 3 can be adjusted forward and backward (refer to Figure 3 as a reference).

[0038] This fixture assembly of the present utility model makes the angle adjustment of the plasma spray gun 2 and the polishing machine 3 very convenient to meet their respective processing requirements and improve the flexibility of processing.

[0039] Refer to Figure 4, a support block 501 for supporting the workpiece 6, a positioning block 502 for positioning the workpiece 6, and a baffle 503 opposite to the cutting part of the workpiece 6 are arranged on the positioning fixture 5. When the workpiece 6 is placed on the positioning fixture 5, the support and positioning of the workpiece 6 are realized through the cooperation of the support block 501 and the positioning block 502, and the handle of the workpiece 6 extends out of the positioning fixture 5 and is in a suspended state. At the same time, the baffle 503 is arranged at a position opposite to the cutting part of the workpiece 6. In this way, when the plasma spray gun 2 cuts, the melted metal at the cutting part is blown away by the ejected high-pressure air flow. By using this positioning fixture 5 to suspend the handle, on the one hand, it can reduce the splashing of the melted metal onto the workpiece, and on the other hand, it enables the cut-off handle to fall freely. At the same time, the baffle 503 is relied on to block the splashing melted metal to prevent spots from forming on the workpiece 6.

[0040] It can be seen that in the integrated plasma cutting and polishing processing equipment of the present utility model, a plasma spray gun 2 and a polishing machine 3 are simultaneously assembled on the robot 1. The positioning fixture 5 is relied on to place and position the workpiece 6 to be processed, ensuring that the workpiece 6 does not shift during the processing. The robot 1 first drives the plasma spray gun 2 to move to the cutting station to perform plasma cutting on the workpiece 6 positioned on the positioning fixture 5. Then, the robot 1 drives the polishing machine 3 to move to the polishing station to polish the part of the workpiece 6 on the positioning fixture 5 that needs to be polished. The waste generated by cutting and polishing will freely fall into the waste cart 7, which is convenient for waste treatment. By integrating the plasma cutting and polishing processes together, the present utility model realizes the continuous operation of cutting and polishing, improves the processing efficiency, can ensure the processing quality, improves the consistency of workpiece processing, and reduces the labor intensity. At the same time, the present utility model adopts a fixture assembly to make the angle adjustment of the plasma spray gun 2 and the polishing machine 3 very convenient to meet their respective processing requirements and improve the flexibility of processing. In addition, while the positioning fixture in the present utility model supports and positions the workpiece, it can also rely on the baffle 503 to block the splashing of the melted metal onto the workpiece 6 to prevent spots from forming on the workpiece 6.
