[0027] This embodiment provides a spraying tooling, as Figure 1 and Figure 2As shown in the figure, it includes a clamping adapter assembly 100 and a tooling rack 200. A clamping head 300 is provided at the opposite first end of the tooling rack 200, and two spaced-apart loading seats 400 are provided at the second end. A first positioning portion 310 is provided in the clamping area of the clamping head 300; the clamping adapter assembly 100 includes a connecting seat 110 and a clamping mechanism 120 provided on the connecting seat 110. A second positioning portion 123a is provided at the clamping end of the clamping mechanism 120. The clamping mechanism 120 detachably clamps the clamping head 300, and the second positioning portion 123a is inserted and positioned in cooperation with the first positioning portion 310.

[0028] This embodiment also provides a spraying device, which includes a robotic arm and the above-mentioned spraying tooling. The connecting seat 110 of the spraying tooling is fixedly connected to the end of the robotic arm.

[0029] When the spraying tooling provided in this embodiment is applied to the spraying device, the tooling rack 200 is fixedly connected to the two loading seats 400 to form an integral body, and the clamping adapter assembly 100 is connected to the robotic arm to form an integral body. During use, first, two workpieces to be sprayed 10, such as multi-piece guide vanes, are loaded on the two loading seats 400, and then the tooling rack 200 is moved to clamp the clamping head 300 at the clamping end of the clamping adapter assembly 100. During the clamping process, the first positioning portion 310 of the clamping head 300 is aligned with the second positioning portion 123a of the clamping mechanism 120. As the clamping end of the clamping mechanism 120 clamps the clamping head 300, the second positioning portion 123a and the first positioning portion 310 move towards each other and are inserted and matched, so as to realize the orientation limitation of the clamping head 300 clamped by the clamping mechanism 120, and correspondingly ensure the movement orientation accuracy of the robotic arm driving the tooling rack 200, the loading seat 400 and the workpieces to be sprayed 10 loaded thereon through the clamping adapter assembly 100, and further ensure the effective spraying of the spraying area of the workpieces to be sprayed 10 by the cooperation of the spray gun and the robotic arm.

[0030] Specifically, during the spraying process, it is necessary to intermittently stop the spraying operation of the workpiece to be sprayed 10 to prevent phenomena such as large thermal stress in the coating, or even cracks, delamination, and peeling caused by the overheating of the workpiece to be sprayed 10, thereby improving the quality of the coating; two loading seats 400 are provided in the spraying tooling provided in this embodiment. During the spraying operation, the intermittent stop time period of one workpiece to be sprayed 10 can be fully utilized to spray the other workpiece to be sprayed 10, so as to realize the alternating continuous spraying of the two workpieces to be sprayed 10, correspondingly ensure the quality of the coating, and shorten the overall spraying time and improve the spraying efficiency.

[0031] After the spraying is completed, adjust the clamping mechanism 120 to loosen the clamping head 300, remove the tooling rack 200, and remove the sprayed product from the loading seat 400 to complete the spraying process of the workpiece to be sprayed 10.

[0032] When the spraying tooling provided in this embodiment is applied to a spraying device, first, the tooling rack 200 is detachably connected to the clamping mechanism 120 of the clamping adapter assembly 100 through the clamping head 300. The tooling rack 200 can be easily disassembled and assembled, thereby improving the spraying production efficiency. Second, during the process of the clamping mechanism 120 clamping the clamping head 300, the second positioning portion 123a can be inserted into cooperation with the first positioning portion 310 to limit the orientation of the clamping head 300 connected to the clamping mechanism 120. Thus, the accuracy of the movement orientation of the robotic arm driving the workpiece to be sprayed 10 through the spraying tooling is improved, the high repeat positioning accuracy of the tooling rack 200 is achieved, and the clamping error rate is reduced. Accordingly, the effective spraying of the spraying area of the workpiece to be sprayed 10 by the cooperation of the spray gun and the robotic arm is ensured, and further the quality of the coating is ensured. Third, the tooling rack 200 is fixedly connected with two loading seats 400, which can load two workpieces to be sprayed 10 at the same time. During the spraying operation, the intermittent stop time period of one workpiece to be sprayed 10 can be fully utilized to spray the other workpiece to be sprayed 10. Thus, the alternate continuous spraying of the two workpieces to be sprayed 10 is realized, the quality of the coating is further ensured accordingly, and the overall spraying time is shortened and the spraying efficiency is improved.

[0033] In this embodiment, the tooling rack 200 is provided with a partition member, and the partition member is disposed between the two loading seats 400. During the process of the spray gun alternately spraying the workpieces to be sprayed 10 loaded on the two loading seats 400, the partition member can effectively block the spraying influence of the substances sprayed by the spray gun on the other workpiece to be sprayed 10, thereby ensuring the spraying effect and the quality of the coating.

[0034] Optionally, in this embodiment, as Figures 1-3 shown, in the two clamping areas on the opposite sides of the clamping head 300, one is provided with a first positioning portion 310, and the other is a first clamping plane 320; among the two clamping ends of the clamping mechanism 120, the end surface of one of them is provided with a second positioning portion 123a, and the other is a second clamping plane 122a. The clamping mechanism 120 has two clamping ends, and the two clamping ends clamp the two opposite sides of the clamping head 300 through opposite movement, or release the clamping of the clamping head 300 through separating movement. Among them, the two side areas where the clamping head 300 and the two clamping ends have a clamping effect are used as clamping areas. One of the clamping areas is provided with a first positioning portion 310, and the other clamping area is a plane as the first clamping plane 320; among the opposite end surfaces of the two clamping ends of the clamping mechanism 120, one is provided with a second positioning portion 123a, and the other is a plane as the second clamping plane 122a.

[0035] During use, adjust the two clamping ends to open a certain distance, move the clamping head 300 between the two clamping ends, and make the first positioning portion 310 face the second positioning portion 123a and the first clamping plane 320 face the second clamping plane 122a; then, adjust the two clamping ends to move towards each other. Among them, the second clamping plane 122a abuts against the first clamping plane 320 to apply a pre-tightening force, and allows the two to perform sliding adjustment along the plane extension direction; the second positioning portion 123a moves towards the first positioning portion 310 and gradually fits into each other until the two clamping ends clamp both sides of the clamping head 300, and the first positioning portion 310 and the second positioning portion 123a complete the plug-in fit positioning, so as to realize the clamping of the clamping mechanism 120 on the clamping head 300, and the orientation of the clamping head 300 is limited by the plug-in fit of the first positioning portion 310 and the second positioning portion 123a.

[0036] Among them, the settings of the first clamping plane 320 and the second clamping plane 122a not only make the structures of the clamping head 300 and the clamping mechanism 120 simple and convenient to process, the two can perform sliding adjustment along the plane extension direction, but also ensure the plug-in fit positioning of the first positioning portion 310 and the second positioning portion 123a.

[0037] Specifically, in this embodiment, as Figures 3-5 shown, among the clamping area of the clamping head 300 and the clamping ends of the clamping mechanism 120, one of them is provided with four positioning grooves 311, the four positioning grooves 311 are arranged in a "cross" shape, and the groove width of each positioning groove 311 gradually decreases along the groove depth direction; the other is provided with four positioning protrusions 123b, and the four positioning protrusions 123b each include a conical positioning section 123d, and the four conical positioning sections 123d are in one-to-one correspondence and fit with the four positioning grooves 311. The cross-section of the four positioning grooves 311 along the groove depth direction is a tapered shape with a reduced opening, and the four positioning grooves 311 are arranged at equal intervals at an angle of 90° in the circumferential direction. Define two of the four positioning grooves 311 that extend collinearly as the first positioning grooves, and the other two positioning grooves 311 that extend collinearly as the second positioning grooves; among the four positioning protrusions 123b, define two opposite positioning protrusions 123b as the first positioning protrusions, and the other two opposite positioning protrusions 123b as the second positioning protrusions.

[0038] When clamping, the clamping head 300 is located between the two clamping ends, and the first clamping plane 320 abuts and is pre-tightened against the second clamping plane 122a. The shrinking ends of the tapered positioning sections 123d of the two first positioning protrusions respectively extend into the two first positioning grooves in a one-to-one correspondence, and the shrinking ends of the tapered positioning sections 123d of the two second positioning protrusions respectively extend into the two second positioning grooves in a one-to-one correspondence. As the two clamping ends are gradually clamped, the insertion depths of the two first positioning protrusions into the two first positioning grooves gradually increase. During this process, the two first positioning grooves provide a centering guiding effect on the two first positioning protrusions along the width direction of the grooves. Similarly, the insertion depths of the two second positioning protrusions into the two second positioning grooves gradually increase, and the two second positioning grooves provide a centering guiding effect on the two second positioning protrusions along the width direction of the grooves. Then, on the basis of the pre-tightening effect, the first clamping plane 320 and the second clamping plane 122a can allow the clamping head 300 to slide and adjust relative to the second clamping plane 122a to ensure the translation movement caused by the centering guiding of the first positioning groove and the second positioning groove on the first positioning protrusion and the second positioning protrusion in the vertical direction respectively, until the tapered positioning sections 123d of the two first positioning protrusions respectively abut against the two first positioning grooves, and the tapered positioning sections 123d of the two second positioning protrusions respectively abut against the two second positioning grooves. While completing the clamping of the clamping head 300 by the clamping mechanism 120, the centering adjustment of the clamping head 300 is also realized through the centering guiding of the second positioning portion 123a on the first positioning portion 310 in two vertical directions, so as to ensure the uniqueness and stability of the orientation of the clamping head 300 clamped by the clamping mechanism 120.

[0039] Specifically, as Figures 3-5 shown, the four positioning grooves 311 can be used as the first positioning portion 310 in a clamping area on one side of the clamping head 300, and the four positioning protrusions 123b are used as the second positioning portion 123a on the end face of the clamping end. Of course, in addition to what is shown in the drawings, the four positioning grooves 311 can also be used as the second positioning portion 123a on the end face of the clamping end, and the four positioning protrusions 123b are used as the first positioning portion 310 in a clamping area on one side of the clamping head 300. Among them, the positioning protrusion 123b can also include a connecting section 123c, and the connecting section 123c is connected between the tapered positioning section 123d and the corresponding clamping area or the end face of the clamping end.

[0040] Specifically, in this embodiment, as Figures 3-5As shown, the conical positioning section 123d is frustum-shaped. The positioning groove 311 includes an insertion groove section 311a and a pre-tightening groove section 311b along the groove depth direction, and the insertion groove section 311a matches the conical positioning section 123d. When the conical positioning section 123d is fitted and abutted against the insertion groove section 311a, there is still a certain gap between the reduced head end of the conical positioning section 123d and the bottom of the positioning groove 311, and this gap is the pre-tightening groove section 311b. The setting of the pre-tightening groove section 311b can ensure a greater degree of abutment between the conical positioning section 123d and the positioning groove 311, and correspondingly ensure the clamping firmness and positioning stability of the clamping mechanism 120 for the clamping head 300.

[0041] Specifically, in this embodiment, as Figure 1 and Figure 2 shown, the clamping mechanism 120 includes a telescopic driving member 121. The housing portion 121a of the telescopic driving member 121 is fixedly provided on the connecting seat 110, and a first jaw 122 is fixedly provided on the side of the housing portion 121a away from the connecting seat 110. The telescopic portion 121b of the telescopic driving member 121 is fixedly provided with a second jaw 123. The telescopic driving member 121 is used to drive the second jaw 123 to move towards or away from the first jaw 122. Specifically, the telescopic driving member 121 can be a driving member in the form of pneumatic, hydraulic, electric, etc. When in use, the first jaw 122 does not move, and the telescopic driving member 121 drives the second jaw 123 to move translationally towards or away from the second jaw 123 to clamp or release the clamping head 300. The structure is simple and the clamping stability is relatively high.

[0042] Specifically, as Figure 1 and Figure 2 shown, the connecting seat 110 includes a first adapter flange 111 and a second adapter flange 112. Among them, the second adapter flange 112 is connected between the housing portion 121a and the first adapter flange 111, and one end of the first adapter flange 111 away from the second adapter flange 112 is adaptively connected to the end flange of the robotic arm.

[0043] In this embodiment, as Figure 1 and Figure 2 ​As shown in the figure, the tooling rack 200 includes two parallel and spaced-apart tooling rods and a connecting arm 210 connected between the two tooling rods. The clamping head 300 is fixedly provided at the first end of one of the tooling rods, and two loading seats 400 are fixedly provided at the second ends of the two tooling rods corresponding to the clamping head 300 one by one. Among the two juxtaposed tooling rods, one is used as the first tooling rod 220 and the other is used as the second tooling rod 230. One end of the first tooling rod 220 is connected to the clamping head 300, and the other end is connected to the loading seat 400. One end of the second tooling rod 230 is connected to the loading seat 400. The first tooling rod 220 and the second tooling rod 230 are connected by the connecting arm 210 to determine the relative position. The structure of the tooling rack 200 is simple, the processing cost is low, and the installation of the clamping head 300 and the two loading seats 400 can be ensured; wherein, the two loading seats 400 are located on the same side and are preferably juxtaposed and spaced apart, so as to facilitate the alternate spraying of the workpieces 10 to be sprayed loaded on the two loading seats 400 by the spray gun.

[0044] Specifically, in this embodiment, there are two connecting arms 210. The two connecting arms 210 are spaced apart along the extending direction of the tooling rod, and the extending direction of the connecting arm 210 is perpendicular to the extending direction of the tooling rod. The two connecting arms 210 are connected to different positions in the length direction of the two tooling rods, and the fixing effect on the two tooling rods is higher and more stable, thereby improving the stability of the tooling rack 200, and correspondingly ensuring the position fixing stability of the two tooling rods for the clamping head 300 and the two loading seats 400.

[0045] In this embodiment, the loading seat 400 is provided with a foolproof loading insertion groove, and correspondingly, the second end of the tooling rod is provided with a loading insertion protrusion, and the loading insertion protrusion is fitted and inserted into the loading insertion groove; when assembling the loading seat 400 and the tooling rod, the loading insertion protrusion of the tooling rod can be fitted and inserted into the loading insertion groove, so as to realize the foolproof limit in the circumferential direction, and correspondingly ensure the uniqueness and accuracy of the orientation of the loading seat 400 connected to the tooling rod, and improve the assembly convenience of the two; then, the loading seat 400 and the tooling rod are fixed by welding or the like to ensure the connection firmness of the two.

[0046] Similarly, the clamping head 300 is provided with a foolproof clamping insertion groove, and correspondingly, the first end of the tooling rod is provided with a clamping insertion protrusion, and the clamping insertion protrusion is fitted and inserted into the clamping insertion groove. When assembling the clamping head 300 and the tooling rod, the clamping insertion protrusion of the tooling rod can be fitted and inserted into the clamping insertion groove, so as to realize the foolproof limit in the circumferential direction, and correspondingly ensure the uniqueness and accuracy of the orientation of the clamping head 300 connected to the tooling rod, and further ensure the uniqueness and accuracy of the orientation of the loading seat 400 relative to the robotic arm after the clamping head 300 is clamped to the clamping mechanism 120, and ensure the driving stroke accuracy of the robotic arm for the workpiece 10 to be sprayed loaded on the loading seat 400; then, the clamping head 300 and the tooling rod can be fixed by welding or the like to ensure the connection firmness of the two.

[0047] Specifically, in this embodiment, as Figure 1 and Figure 2 shown, the loading seat 400 includes a first fixture 410 fixedly connected to the tooling rack 200 and a second fixture 420 detachably fixed to the first fixture 410. The first fixture 410 and the second fixture 420 are spaced apart to form a loading space 430, and the loading space 430 matches the part 10 to be sprayed. The first fixture 410 and the second fixture 420 clamp the part 10 to be sprayed, which can effectively protect the non-spraying area of the part 10 to be sprayed (such as the guide vane), and at the same time do not block its spraying area and transition area.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
