DETAILED DESCRIPTION

[0031] The following will be combined with the drawings Figures 1-4 Further details of the present application are described.

[0032] The embodiment of the present application discloses a clamping device for double-channel scroll.

[0033] A double-channel scroll includes a first tube body 71 and a second tube body 72. The second tube body 72 is arranged on the first tube body 71, and the interior of the first tube body 71 is communicated with the interior of the second tube body 72. The end of the first tube body 71 is provided with a connecting pipe 711, and a limiting ring 712 is coaxially arranged on the outer wall of the connecting pipe 711. The thickness of the limiting ring 712 gradually increases from the direction away from the first tube body 71 to the direction close to the first tube body 71.

[0034] A bushing includes a placement pipe 81 and a fixing ring 82. The fixing ring 82 is coaxially arranged on the outer wall of the end of the placement pipe 81, and the placement pipe 81 and the fixing ring 82 are integrally formed.

[0035] The clamping device for double-channel scroll includes a mechanical arm 1, a mounting plate 2, a first clamping part 3 and a second clamping part 4. The mounting plate 2 is arranged on the end of the mechanical arm 1, the first clamping part 3 and the second clamping part 4 are arranged on the same side of the mounting plate 2, the first clamping part 3 and the second clamping part 4 are respectively arranged on the two ends of the mounting plate 2, and the clamping end of the first clamping part 3 and the clamping end of the second clamping part 4 are away from each other.

[0036] When the double-channel scroll 7 and the bushing 8 are carried, the first clamping part 3 and the second clamping part 4 are simultaneously driven to move by the mechanical arm 1, the double-channel scroll 7 is clamped by the first clamping part 3, and the bushing 8 is clamped by the second clamping part 4. Since the equipment for carrying the double-channel scroll 7 and the bushing 8 is integrated on a set of carrying equipment, the floor space of the carrying equipment is reduced, and the cost for maintaining the carrying equipment is reduced. When the bushing 8 needs to be installed on the double-channel scroll 7, since the double-channel scroll 7 and the bushing 8 are simultaneously carried, the efficiency of placing the bushing 8 close to the double-channel scroll 7 is improved.

[0037] The first clamping part 3 includes a pair of clamping pieces 31 with adjustable spacing, and the clamping piece 31 includes a connecting plate 32 and a clamping strip 33. The connecting plate 32 is close to or away from the mounting plate 2 by a power source 34 arranged on the mounting plate 2, the clamping strip 33 is arranged on the connecting plate 32 by a locking piece 5, and the clamping strip 33 is positioned with the connecting plate 32 by a positioning piece 6. The clamping strip 33 is located on the side where the two clamping pieces 31 are close to each other.

[0038] When the double-channel scroll 7 is clamped, the pair of clamping pieces 31 are close to each other, and the double-channel scroll 7 is clamped by the two clamping strips 33. When the clamping strip 33 is installed on the connecting plate 32, the clamping strip 33 is installed on the connecting plate 32 by the positioning piece 6, and then the clamping strip 33 is fixed on the connecting plate 32 by the locking piece 5. In this way, the clamping strip 33 is conveniently installed on the connecting plate 32, and the clamping strip 33 is conveniently replaced, so as to adapt to different models of the double-channel scroll 7.

[0039] In the embodiment of the present application, the power source 34 of the pair of clamping pieces 31 is a double-headed cylinder, which moves synchronously. The locking piece 5 is a locking bolt, which penetrates the connecting plate 32 and the clamping strip 33, and the connecting plate 32 and the clamping strip 33 are threadedly connected with the locking bolt. The convenience of disassembling and assembling the clamping strip 33 is improved by connecting the clamping strip 33 and the connecting plate 32 through the locking bolt.

[0040] The positioning piece 6 is a positioning strip, which is arranged on the side of the connecting plate 32 close to the clamping strip 33. The side of the clamping strip 33 close to the connecting plate 32 is provided with a positioning groove 332 which is in sliding cooperation with the positioning strip. Before the clamping strip 33 is installed on the connecting plate 32, the clamping strip 33 and the connecting plate 32 are moved close to each other, and the positioning strip is placed in the positioning groove 332. The convenience of installing the clamping strip 33 on the connecting plate 32 through the locking bolt is improved by the cooperation between the positioning strip and the positioning groove 332. Meanwhile, when the clamping strip 33 and the connecting plate 32 are not connected through the locking bolt, the cooperation between the positioning strip and the positioning groove 332 facilitates the guiding of the movement of the clamping strip 33 on the connecting plate 32. Meanwhile, the positioning strip and the connecting plate 32 are integrally formed, thereby improving the structural strength of the connecting plate 32 and the working life of the connecting plate 32.

[0041] The clamping strip 33 is provided with a clamping groove 331 which is in plug-in cooperation with the limiting ring 712 of the double-flow volute 7. The width of the clamping groove 331 gradually increases from the direction close to the connecting plate 32 to the direction away from the connecting plate 32. When the double-flow volute 7 is clamped by the clamping strip 33, the limiting ring 712 is placed in the clamping groove 331. Since the width of the clamping groove 331 gradually increases from the direction close to the connecting plate 32 to the direction away from the connecting plate 32, the limiting ring 712 gradually enters the clamping groove 331, and the inner wall of the clamping groove 331 and the limiting ring 712 are easily attached, thereby improving the stability of carrying the double-flow volute 7.

[0042] The side of the clamping strip 33 away from the connecting plate 32 is provided with a circular arc surface 333 which is in contact with the outer wall of the connecting pipe 711 of the double-flow volute 7. The contact between the circular arc surface 333 and the connecting pipe 711 further improves the stability of clamping the double-flow volute 7. Meanwhile, the circular arc surface 333 can be replaced by a groove, and the stability of clamping the double-flow volute 7 is improved by the multi-point contact between the inner wall of the groove and the outer wall of the connecting pipe 711.

[0043] The second clamping part 4 includes a pair of adjustable spacing pickup strips 41, and the side of the pickup strip 41 close to each other is provided with a groove for placing the bushing 8. When the bushing 8 is clamped, the pickup strip 41 clamps the bushing 8, and the bushing 8 is placed in the groove, thereby improving the stability of clamping the bushing 8. In the embodiment of the present application, the pair of pickup strips 41 moves synchronously through the double-headed cylinder. When the bushing 8 is clamped, the pickup strip 41 clamps the bushing 8 close to the position of the fixed ring 82.

[0044] The implementation principle of the clamping device for the double-flow channel scroll is as follows: in the process of carrying the double-flow channel scroll 7 and the bushing 8, first, the first clamping part 3 and the second clamping part 4 on the mounting plate 2 at the end of the mechanical arm 1 are operated. The first clamping part 3 is composed of a pair of clamping pieces 31 with adjustable spacing, the clamping piece 31 includes a connecting plate 32 and a clamping strip 33, the connecting plate 32 is driven to approach or move away from the mounting plate 2 by a double-head air cylinder, and the clamping strip 33 is fixed with the connecting plate 32 by locking bolts and positioning strips. When clamping the double-flow channel scroll 7, the double-head air cylinder makes the pair of clamping pieces 31 approach each other, the clamping groove 331 on the clamping strip 33 cooperates with the limiting ring 712 of the double-flow channel scroll 7, the width of the clamping groove 331 gradually increases from the direction close to the connecting plate 32 to the direction away from the connecting plate 32, which facilitates the limiting ring 712 to gradually enter and fit, and at the same time, the arc surface 333 on the side of the clamping strip 33 away from the connecting plate 32 contacts the outer wall of the connecting pipe 711, further improving the clamping stability. The second clamping part 4 is composed of a pair of pickup strips 41 with adjustable spacing, the pickup strip 41 is provided with a groove on the side close to each other for placing the bushing 8, and the pickup strip 41 is driven by the double-head air cylinder to clamp the bushing 8, so that the bushing 8 is placed in the groove, ensuring the stability of clamping the bushing 8. In the whole process, the mechanical arm 1 simultaneously drives the first clamping part 3 and the second clamping part 4 to move, realizing the synchronous carrying of the double-flow channel scroll 7 and the bushing 8, reducing the equipment floor space, reducing the maintenance cost, and improving the efficiency of placing the bushing 8 close to the double-flow channel scroll 7.

[0045] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application should be covered within the protection scope of the present application.
