[0021] Refer to the attached Figures 1 - 3 , The TiCN material spraying equipment includes a painting robot 1 and a plasma spray gun 2, and the plasma spray gun 2 is clamped and installed at the end of the painting robot 1 through a quick connection fixture 3.

[0022] In this embodiment, the quick connection fixture 3 includes a fixed seat 304 and two symmetrically arranged clamping arms. The clamping arms are similar to human fingers and can only be bent unilaterally, and can be bent and clamped according to the shape of the outer wall of the object to be clamped. The pull wire 310 in the clamping arm is similar to the tendon of a human finger. The clamping arm includes a first chain plate 305 and a second chain plate 306. The head end of the first chain plate 305 is hinged to the end of the fixed seat 304, and the end of the second chain plate 306 is hinged to the end of the first chain plate 305. On both sides of the fixed seat 304, a first limit block 312 for restricting the rotation angle of the first chain plate 305 is fixedly installed. The first limit block 312 is mainly used to restrict the rotation angle of the first chain plate 305, so that the included angle between the outer sides of the fixed seat 304 and the first chain plate 305 is greater than 90°. On the outer end face of the first chain plate 305, a second limit block 315 for restricting the rotation angle of the second chain plate 306 is fixedly installed. The second limit block 315 is mainly used to restrict the rotation angle of the second chain plate 306, so that the included angle between the outer sides of the first chain plate 305 and the second chain plate 306 is greater than 180°.

[0023] In this embodiment, the inner end faces of the above-mentioned fixed seat 304, the first link plate 305, and the second link plate 306 are respectively provided with tensioned wire ropes 310 through a plurality of guiding hole blocks 316. The first ends of the two wire ropes 310 in the quick connection fixture 3 are pulled by a power source, and through the bending guidance of the plurality of guiding hole blocks 316, the first link plate 305 and the second link plate 306 in the two clamping arms are symmetrically bent. The ends of the two second link plates 306 in the two clamping arms are successively hinged with a third link plate 307 and a fourth link plate 308. Similarly, in order to limit the rotation angles of the third link plate 307 and the fourth link plate 308, second limiting blocks 315 are fixedly installed on the outer end faces of the second link plate 306 and the third link plate 307. The plurality of guiding hole blocks 316 are respectively fixedly installed on the inner end faces of the first link plate 305, the second link plate 306, the third link plate 307, the fourth link plate 308 in the two clamping arms and the fixed seat 304, mainly for guiding the movement of the wire rope 310. The ends of the wire rope 310 are respectively fixedly connected to the guiding hole blocks 316 on the fourth link plate 308 in the two clamping arms.

[0024] In this embodiment, grooves 313 are provided on the outer end faces of the first link plate 305, the second link plate 306, the third link plate 307, and the fourth link plate 308. Connecting columns 314 are fixedly installed on the inner walls of the grooves 313. A tensioned rubber band 311 is connected between the connecting column 314 on the first link plate 305 and the first limiting block 312 on the fixed seat 304, and between the connecting column 314 on the second link plate 306 and the second limiting block 315 on the first link plate 305. Similarly, rubber bands 311 are also connected between the outer sides of the hinged third link plate 307 and the fourth link plate 308, and between the outer sides of the hinged second link plate 306 and the third link plate 307. In this application, the quick connection fixture 3 uses the above-mentioned tensioned rubber bands 311 to automatically stretch the first link plate 305, the second link plate 306, the third link plate 307, and the fourth link plate 308 in the clamping arms to bend and reset outward, that is, the above-mentioned rubber bands 311 are used to automatically open the quick connection fixture 3.

[0025] In this embodiment, the power source is specifically composed of a hydraulic cylinder 301. The hydraulic cylinder 301 is fixedly installed at the end of the painting robot 1. The hydraulic cylinder 301 is coaxially and fixedly connected to the fixed seat 304 through two connecting plates 303 respectively. The end of the piston rod 302 in the hydraulic cylinder 301 is fixedly connected to the first ends of the wire ropes 310 in the two clamping arms. The first ends of the two wire ropes 310 pass through the wire passing holes in the fixed seat 304. Two rubber clamping blocks 309 are fixedly installed on the inner end faces of the first link plate 305 and the second link plate 306. The two rubber clamping blocks 309 are arranged on both sides of the wire rope 310. The thickness of the rubber clamping block 309 is greater than the height of the guiding hole block 316.

[0026] For this utility model, the process of the painting robot 1 clamping the plasma spray gun 2 through the quick-connect fixture 3 is as follows:

[0027] 1), Open the opening of the quick-connect fixture 3

[0028] First, extend the piston rod 302 of the hydraulic cylinder 301 outwards. The piston rod 302 at the outwards extending end is used to gradually loosen the end of the wire 310 in the two clamping arms, and then, in cooperation with the elastic tension of the eight rubber bands 311 outside the two clamping arms, it is used to gradually rotate and open the link plates one 305, link plates two 306, link plates three 307, and link plates four 308 in the clamping arms, as Figure 3 ;

[0029] 2), Positioning

[0030] Through the painting robot 1, the opening after the quick-connect fixture 3 is opened is vertically aligned with the outer wall of the plasma spray gun 2;

[0031] 3), Clamping

[0032] By contracting the piston rod 302 of the hydraulic cylinder 301 inwards, gradually pull down the end of the wire 310 in the two clamping arms, as Figure 3 , the two gradually tightened wires 310, guided by multiple guide hole blocks 316, are used to guide the fixed seat 304, two link plates one 305, two link plates two 306, two link plates three 307, and two link plates four 308 in the quick-connect fixture 3 to symmetrically fold and bend, gradually approaching the two outer walls of the clamped plasma spray gun 2. It is similar to a human using two fingers to grasp the plasma spray gun 2 and can be bent and folded along the outer wall shape of the plasma spray gun 2 with different shapes and sizes;

[0033] It can be seen that the painting robot 1 can complete the clamping and disassembly of the plasma spray gun 2 by only extending and retracting the piston rod 302 in the hydraulic cylinder 301. Compared with the traditional connecting frame that fixes the plasma spray gun 2 with bolts, the disassembly and installation are faster and more convenient.

[0034] The above is only the preferred specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by this utility model, according to the technical solution of this utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of this utility model.
