In addition, the directional words mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only referenced to the directions of the drawings. Therefore, the directional words used are used to illustrate rather than limit the invention.

[0029] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0030] Embodiment: A flange feeding device for pipe flange welding, see attached Figure 1 -Attached Figure 5 , including a chassis 1, a support plate 2 and a support mechanism, wherein the chassis 1 is configured as a circular disk with a vertical axis and the diameter of the circular disk is greater than the outer diameter of the flange; the support plates 2 are provided in plurality and are arranged around the axis of the chassis 1; the support mechanisms are provided in plurality and are arranged above the chassis 1, and the plurality of support mechanisms are arranged vertically above the chassis 1, and a flange is placed on the top of each support mechanism.

[0031] By setting up multiple supporting mechanisms, the distance between two adjacent flanges can be increased by the supporting mechanisms, so that the clamping mechanism can grasp the flange more easily. In this embodiment, the device for grasping the flange uses a multi-axis robot arm, and a three-jaw chuck is connected to the multi-axis robot arm. The three-jaw chuck is used to grasp the flange, and the multi-axis robot arm drives the three-jaw chuck to move the flange. Specifically, the claws of the three-jaw chuck are arranged to include a claw plate 7 and a limit block 8 fixedly connected to the claw plate 7 near the flange. When the three-jaw chuck grasps the flange, the limit block 8 is inserted between the two adjacent flanges and contacts the bottom of the flange grasped by the claw plate 7. When the claw plates 7 of the three claws clamp the flange, the limit blocks 8 on the three claw plates 7 fit the bottom of the flange, so that the grasping process can grasp the flange without using a large force, so it is not easy to damage the flange.

[0032] The support mechanism includes multiple support components, and the multiple support components of each support mechanism correspond to multiple support plates 2 respectively; the support component includes a sliding rod 3, a clamping plate 4 and an elastic member 5, the sliding rod 3 passes through the corresponding support plate 2 and can slide on the support plate 2 along the radial direction of the chassis 1, the length direction of the sliding rod 3 is set along its own sliding direction, and the flange supported by the support mechanism is supported on the sliding rods 3 of multiple support components at the same time; the clamping plate 4 is fixedly connected to one end of the sliding rod 3 close to the axis of the chassis 1 and the top height of the clamping plate 4 is higher than the top height of the sliding rod 3 so that the clamping plate 4 can be inserted upward into the inner hole of the flange; the elastic member 5 is used to apply an elastic force to the sliding rod 3 in the direction away from the axis of the chassis 1 so that the clamping plate 4 is clamped on the hole wall of the inner hole of the flange, and when the elastic member 5 is in a normal state, the distance between the clamping plate 4 and the axis of the flange is greater than the outer diameter of the flange.

[0033] When the flange is supported on multiple supporting components of the same group, the sliding rods 3 of the multiple supporting components are slid to make the card plate 4 close to the axis of the chassis 1, and then the flange is sleeved outside the multiple card plates 4 and supported on the top of the sliding rods 3 of the multiple supporting components, and the limit of the card plate 4 is released. Under the action of the elastic member 5, the multiple card plates 4 are pressed against the hole wall of the inner hole of the flange. Through the joint action of the multiple card plates 4, the centering of the flange is achieved, and the support of the flange is also achieved. When the flange is loaded, the flange located at the top is first grabbed by the three-jaw chuck. After the flange is grabbed, the flange is lost. The multiple card plates 4 that position the flange slide in the direction away from the axis of the chassis 1 under the action of the elastic member 5 until the elastic member 5 is in a normal state. At this time, the distance between the card plate 4 and the axis of the chassis 1 is greater than the outer diameter of the flange, so that when the three-jaw chuck grabs the next layer of flange, the supporting assembly that supports and positions the upper layer of flange will not cause obstruction to the three-jaw chuck.

[0034] Specifically, the clamping plate 4 is configured as an arc-shaped plate so that the clamping plate 4 can fit with the hole wall of the inner hole of the flange.

[0035] Specifically, the top of the clamping plate 4 is flush with the top of the flange, and in two adjacent support mechanisms, the two clamping plates 4 connected to the same support plate 2 are stacked together. By stacking two adjacent clamping plates 4 together, the support stability of the support assembly can be enhanced, so that the flange can be stably supported on the support mechanism.

[0036] Specifically, the top of the cardboard 4 is fixedly connected with a magnetic block 41; the bottom of the cardboard 4 is provided with a slide groove 42 which penetrates the cardboard 4 along the sliding direction of the sliding rod 3 and cooperates with the magnetic block 41, and the magnetic block 41 can be magnetically attracted to the cardboard 4. The cardboard 4 is configured to be a metal material that can be magnetically attracted by the magnetic block 41; the configuration of the magnetic block 41 can enhance the stability of the adjacent cardboards 4 stacked together, and the configuration of the slide groove 42 ensures that the cardboards 4 will not cause obstruction to each other when sliding.

[0037] The adsorption force of the magnetic block 41 on the card plate 4 is smaller than the elastic force of the elastic member 5 , so that the elastic member 5 can smoothly drive the sliding rod 3 to slide.

[0038] Specifically, each support assembly includes two sliding rods 3, the length directions of the two sliding rods 3 are parallel, and the two sliding rods 3 are arranged in a horizontal direction perpendicular to their length directions. The elastic member 5 is set as a spring, and each sliding rod 3 is sleeved with an elastic member 5; the elastic member 5 is set on the side of the support plate 2 away from the axis of the chassis 1, and the end of the sliding rod 3 away from the clamping plate 4 is fixedly connected to the limit plate 6, and the two ends of the elastic member 5 are respectively pressed against the support plate 2 and the limit plate 6.

[0039] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
