Description

Technical Field

[0001] This application relates to the field of fixture and tooling technology, and in particular to a fixture and tooling for supporting steel pipes for marine satellites. Background Technology

[0002] The satellite support steel pipe consists of a column and three side plates, which are evenly welded and fixed to the perimeter of the column. When welding and assembling the satellite support steel pipe, due to the length and weight of the column, one worker needs to straighten the column, and then another worker welds and fixes the three side plates to the perimeter of the column in turn. The span angle between adjacent side plates needs to be the same, which further increases the installation difficulty of the satellite support steel pipe. Utility Model Content

[0003] The purpose of this utility model is to provide a marine satellite support steel pipe clamping fixture in response to the defects and deficiencies of the existing technology.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The device includes a processing platform and a fixing device. The fixing device is located on the processing platform and includes a support frame, a stabilizing ring, and a disc. One side of the stabilizing ring is horizontally mounted on the support frame. The disc is located directly below the stabilizing ring. Three limiting arcs are evenly arranged circumferentially on the upper surface of the disc. The lower end of the column is located between the three limiting arcs. Three clamping plates are evenly arranged circumferentially on the upper surface of the disc. The upper end of each clamping plate has a placement groove for placing a side plate. The clamping plate is located between two adjacent limiting arcs.

[0006] Preferably, there are three fixing devices, which are evenly placed circumferentially, and a partition plate is vertically arranged between two adjacent fixing devices.

[0007] Preferably, the stabilizing ring consists of two fixed half-rings, with one end of the two fixed half-rings rotatably connected to each other. A driving cylinder is provided between the fixed half-rings and the partition plate, and the driving cylinder drives the fixed half-rings to rotate.

[0008] Preferably, the lower end of the disk is circumferentially and uniformly connected with a plurality of ball bearings.

[0009] Preferably, the upper end of the processing platform is provided with three mounting rings evenly distributed around its circumference, and the disk is located within the mounting rings.

[0010] Preferably, the side wall of the clamping plate is threadedly connected to a fixing screw, one end of which passes through the side wall of the clamping plate and is inserted into the placement groove.

[0011] Preferably, a hydraulic cylinder is vertically installed at the lower end of the processing platform.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] 1. When assembling the satellite support steel pipe, activate two drive cylinders to rotate two fixed half-rings, opening the stabilizing ring. Place the column between the two fixed half-rings, and then rotate the two fixed half-rings again to close the stabilizing ring, clamping the column. Place the lower end of the column against the upper end of the disc, positioning it between three limiting arcs. Place the three side plates into the slots of the three clamping plates, ensuring the inner side of the side plates abuts against the side wall of the column. Then, rotate the fixing screw to fix the side plates in the slots. Finally, weld the contact surfaces between the column and the three side plates. This process allows for quick and stable assembly of the satellite support steel pipe, reducing the installation difficulty.

[0014] 2. When it is necessary to place the column on the processing platform, the hydraulic cylinder is activated to lower the processing platform, which makes it easier to place the column on the processing platform and improves the convenience of assembling satellite support steel pipes.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] This application discloses a marine satellite support steel pipe clamping fixture.

[0021] Reference Figure 1 and Figure 2The system includes a processing platform 1 and three fixing devices 2. The three fixing devices 2 are located on the processing platform 1 and are evenly placed in a circumferential direction. A partition plate 3 is placed vertically between two adjacent fixing devices 2. Each fixing device 2 includes a support frame 4, a stabilizing ring 5, and a disc 6. A circular frame 7 is placed horizontally between the three fixing devices 2. The upper ends of the three partition plates 3 are fixed to the lower ends of the circular frame 7, and the lower ends of the partition plates 3 are fixed to the upper surface of the processing platform 1. One end of the support frame 4 is fixed to the side wall of the circular frame 7 by bolts. The stabilizing ring 5 is fixed to the outer end of the support frame 4. The disc 6 is placed on the processing platform 1, and the stabilizing ring 5 and the disc 6 are vertically aligned.

[0022] The stabilizing ring 5 consists of two fixed half-rings 8. One end of each fixed half-ring 8 is rotatably connected to the outer end of the support frame 4. A driving cylinder 9 is placed between the fixed half-ring 8 and the partition plate 3. One end of the driving cylinder 9 is rotatably connected to the outer side of the fixed half-ring 8, and the other end of the driving cylinder 9 is rotatably connected to one side of the partition plate 3.

[0023] Reference Figure 3 Three mounting rings 10 are evenly fixed at the upper end of the processing platform 1, and the disc 6 can be placed inside the mounting rings 10. The mounting rings 10 allow the disc 6 to be vertically and stably aligned with the stabilizing ring 5.

[0024] Multiple balls 11 are circumferentially and evenly connected to the lower end of the disc 6, with the lower ends of the balls 11 abutting against the upper surface of the processing platform 1. The disc 6 can rotate within the mounting ring 10 under the action of the balls 11. After the column and three side plates are placed on the disc 6, the side plates to be welded are oriented outwards under the rotation of the disc 6, thus facilitating the welding of the satellite support steel pipe.

[0025] The upper surface of the disc 6 is uniformly and integrally provided with three limiting arcs 12, and the lower end of the column is located between the three limiting arcs 12. The three limiting arcs 12 can restrict the lower end of the column to the disc 6, preventing the lower end of the column from swaying left and right.

[0026] Three clamping plates 13 are evenly fixed on the upper surface of the disc 6. The three clamping plates 13 are located outside the three limiting arcs 12. The clamping plates 13 are located between two adjacent limiting arcs 12. A placement groove 14 is opened at the upper end of the clamping plate 13. The opening direction of the placement groove 14 is towards the center of the disc 6. The placement groove 14 can be used to place the side plate.

[0027] A fixing screw 15 is rotatably connected to the side wall of the clamping plate 13 via an internal thread. One end of the fixing screw 15 passes through the side wall of the clamping plate 13 and is inserted into the placement groove 14. After the side plate is placed in the placement groove 14, the fixing screw 15 is rotated so that the inner end of the fixing screw 15 presses against the side wall of the side plate, thereby fixing the side plate in the placement groove 14.

[0028] Reference Figure 1 A hydraulic cylinder 16 is vertically placed at the lower end of the processing platform 1. The upper end of the hydraulic cylinder 16 is fixed to the lower end face of the processing platform 1, and a base is fixed to the lower end of the hydraulic cylinder 16, with the base in contact with the ground. When it is necessary to place the column on the processing platform 1, the hydraulic cylinder 16 is activated to lower the processing platform 1, thereby facilitating the placement of the column on the processing platform 1.

[0029] The implementation principle of a marine satellite support steel pipe clamping fixture disclosed in this application is as follows:

[0030] Activate the two drive cylinders 9 to drive the two fixed half-rings 8 to rotate, thus opening the stabilizing ring 5. Then, place the column between the two fixed half-rings 8, and then drive the two fixed half-rings 8 to rotate, thus closing the stabilizing ring 5 and clamping the column. Then, place the lower end of the column against the upper end of the disc 6, positioning the lower end of the column between the three limiting arcs 12. Next, place the three side plates into the placement slots 14 of the three clamping plates 13, so that the inner side of the side plate abuts against the side wall of the column. Then, rotate the fixing screw 15 to fix the side plate in the placement slot 14. Finally, rotate the fixing screw 15 to lock the side plate in the placement slot 14. After that, the contact surfaces between the column and the three side plates can be welded and fixed.

[0031] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
