[0033] Below, combined Figures 1 to 3 , the above-mentioned flange clamp 100 is further explained.

[0034] like Figure 2 As shown, the base plate 10 has a discharge position 11 for the flange 202 of the swing elbow flange 200, and the positioning mechanism 20 includes a positioning block 21, a guide assembly 22, a limit plate 23 and an elastic member 24. The positioning block 21 and the guide assembly 22 are both connected to the base plate 10 and are used to position the flange 202. The positioning block 21 is set at the discharge position 11, the guide assembly 22 is connected to the base plate 10, and the limit plate 23 is installed on the guide assembly 22. A card groove 231 is provided on the side of the limit plate 23 close to the base plate 10. The card groove 231 is used to clamp the flange 202, and the elastic member 24 is used to provide elastic force for the limit plate 23 to approach the discharge position 11.

[0035] Specifically, if Figure 3 As shown, the guide assembly 22 includes a guide member 221 and an adapter block 222. The guide member 221 is installed on the base plate 10 and is slidably connected to the adapter block 222. The adapter block 222 is connected to the limit plate 23, wherein the guide member 221 is a bolt. More specifically, the guide member 221 includes a guide rod 223 and a blocking head 224. The guide rod 223 is connected to the base plate 10, and the blocking head 224 is arranged at the end of the guide rod 223 away from the base plate 10. The adapter block 222 is slidably connected to the guide rod 223. In order to improve the guiding accuracy of the adapter block 222, the number of guide members 221 is two, and the two guide members 221 are arranged at intervals.

[0036] In order to facilitate the control of the distance between the limiting plate 23 and the discharge position 11 of the substrate 10, the limiting plate 23 is adapted to the flanges 202 of different diameters, such as Figure 3As shown, the guide assembly 22 also includes an adjusting member 225, which is a hand-tightened nut and is threadedly connected to the adapter block 222. The adjusting member 225 passes through the adapter block 222 and is supported by the base plate 10. In order to facilitate the control of the displacement accuracy of the limit plate 23, the base plate 10 is provided with a scale mark 12, and the scale mark 12 is set corresponding to the limit plate 23.

[0038] like Figure 3 As shown, the pressing claw mechanism 30 is installed on the base plate 10 and is connected to the driving mechanism 40. The driving mechanism 40 drives the pressing claw mechanism 30 to move closer to or away from the discharge position 11, so that the flange 202 is pressed against the pressing claw mechanism 30 and the base plate 10 to achieve the fixation of the elbow flange 200. Specifically, the pressing claw mechanism 30 includes a rotating seat 31, a rotating shaft 32 and a pressing claw 33. The rotating seat 31 is connected to the base plate 10, the rotating shaft 32 is connected to the rotating seat 31, and the pressing claw 33 is provided with a guide groove 331 movably connected to the rotating shaft 32. The driving mechanism 40 drives the clamping claw 33 to approach or move away from the discharge position 11, wherein the number of the clamping claw mechanisms 30 is two, and the two clamping claw mechanisms 30 are respectively arranged on both sides of the substrate 10. The driving mechanism 40 includes a driving member 41 and a guide seat 42. The driving member 41 is a cylinder and is connected to the substrate 10. The driving member 41 drives the guide seat 42 to approach or move away from the substrate 10. The guide seat 42 is rotatably connected to the clamping claw 33 to drive the end of the clamping claw 33 away from the guide seat 42 to approach or move away from the substrate 10 around the rotating shaft 32.

[0039] The flange clamp 100 provided in the present application is used as follows: hold the handle 233 of the limiting plate 23 and pull the plate body 232 away from the discharge position 11, and connect the flange piece 202 of the elbow flange 200 with the positioning block 21 of the positioning mechanism 20, release the handle 233, and the elastic force of the elastic member 24 pushes the slot 231 of the limiting plate 23 to engage with the flange piece 202 of the elbow flange 200 to achieve preliminary fixation of the elbow flange 200, start the driving member 41 of the driving mechanism 40, and drive the guide seat 42 to control the clamping claw 33 to rotate around the rotating shaft 32, so that the clamping claw 33 is away from the end of the guide seat 42 and approaches the substrate 10, thereby cooperating with the base, clamping the flange piece 202 of the elbow flange 200, and achieving fixation of the elbow flange 200.

[0040] The beneficial effect of the flange clamp 100 provided in the present application is that: the positioning block 21 of the positioning block 21 is used to position the flange 202, the elastic member 24 pushes the limit plate 23 close to the discharge position 11, so that the slot 231 of the discharge position 11 is clamped to the flange 202, and the driving mechanism 40 drives the pressure claw mechanism 30 to cooperate with the base plate 10 to support the flange 202, which is beneficial to quickly fix the flange 202 of the elbow flange 200 through the cooperation of the positioning mechanism 20 and the pressure claw mechanism 30, thereby reducing the time for fixing the elbow flange 200 and achieving the purpose of improving the processing efficiency of the elbow flange 200.
