DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] In order to further understand the content, features and effects of the present utility model, the following embodiments are cited and described in detail in conjunction with the accompanying drawings as follows.

[0025] As Figures 1 to 5 shown, a casing docking device provided by an embodiment of the present utility model includes a support 1, and the support 1 is welded by multiple groups of steel pipes. The main function of the support 1 is to support the device.

[0026] A platform 2 is fixedly connected to the upper end of the support 1. The platform 2 is rectangular and made of stainless steel. The main function of the platform 2 is to serve as a workbench for placing casings and other items.

[0027] An adjusting block 3 is fixedly connected to the upper end of the platform 2. A hole is provided in the adjusting block 3, and a first rotating shaft 4 is rotatably connected in the hole. A groove is provided on one side of the adjusting block 3, and a driving assembly 9 is arranged in the groove. The driving assembly 9 is used to drive the first rotating shaft 4 to rotate.

[0028] The driving assembly 9 includes a first motor 901. The first motor 901 is fixedly connected to the inner wall of the groove of the adjusting block 3. The output end of the first motor 901 is fixedly connected with a first gear 902. One end of a first rotating shaft 4 is fixedly connected with a second gear 903. The first gear 902 meshes with the second gear 903. After the first gear 902 rotates, it can drive the second gear 903 to rotate.

[0029] After the first motor 901 is started, it drives the first gear 902 to rotate. The first gear 902 drives the second gear 903 to rotate. The second gear 903 then drives the first rotating shaft 4 to rotate, thereby driving the connecting block 5 and the fixing rod 6 to rotate, and also driving the sleeve fixed in the fixed tube 7 to rotate, so that the back of the sleeve rotates over, facilitating welding around the sleeve.

[0030] A connecting block 5 is fixedly connected to the outer wall of the first rotating shaft 4. The connecting block 5 is rotatably connected with a fixing rod 6. An avoidance groove is formed on one side of the connecting block 5. The inner wall of the avoidance groove is rotatably connected with a second rotating shaft 10. The fixing rod 6 is fixedly connected to the second rotating shaft 10. A placement groove is formed on the inner wall of the avoidance groove of the connecting block 5. A second motor 11 is fixedly connected to the inner wall of the placement groove. The output end of the second motor 11 is fixedly connected with a third gear 12. A fourth gear 13 is fixedly connected to the middle of the second rotating shaft 10. The third gear 12 meshes with the fourth gear 13. After the third gear 12 rotates, it can drive the fourth gear 13 to rotate.

[0031] After the second motor 11 is started, it drives the third gear 12 to rotate. The third gear 12 then drives the fourth gear 13 to rotate. The fourth gear 13 drives the second rotating shaft 10 to rotate. The second rotating shaft 10 drives the fixing rod 6 to rotate, so that the fixed tube 7 on the fixing rod 6 rotates, enabling the welding angle of the sleeve to be changed.

[0032] The fixing rod 6 is fixedly connected with a fixed tube 7. A fixing assembly 8 is arranged on the fixed tube 7. The fixing assembly 8 includes a sector block 801. Multiple groups of sector blocks 801 are provided, all made of stainless steel material. When multiple groups of sector blocks 801 contract inward, they can clamp the sleeve in the fixed tube 7, thereby fixing the sleeve. One side of the sector block 801 is fixedly connected with an adjusting rod 802. A through hole is formed on the outer wall of the fixed tube 7. The adjusting rod 802 passes through the through hole.

[0033] A spring 803 is sleeved on the adjusting rod 802. One end of the spring 803 is fixedly connected to one side of the sector block 801. The other end of the spring 803 is fixedly connected to the inner wall of the fixed tube 7. One end of the adjusting rod 802 is fixedly connected with a slider 808. An adjusting tube 804 is sleeved on the fixed tube 7. A slideway is formed in the adjusting tube 804. The slider 808 is slidably connected in the slideway.

[0034] The slideway inside the adjusting pipe 804 is sloped, such that the position where the slider 808 slides inside the slideway will change, thereby causing the slider 808 to move, which in turn drives the adjusting rod 802 to move, and the adjusting rod 802 then drives the sector block 801 to move, so that the sector block 801 can contract inwards to fix the sleeve in the fixed pipe 7.

[0035] A threaded hole is provided at the upper end of the adjusting pipe 804. A threaded rod 805 is rotatably connected inside the threaded hole. A fixed block 806 is fixedly connected to the fixed pipe 7. The threaded rod 805 is rotatably connected to the fixed block 806. One end of the threaded rod 805 is fixedly connected to an adjusting knob 807.

[0036] Rotating the adjusting knob 807 can drive the threaded rod 805 to rotate. After the threaded rod 805 rotates, the fixed block 806 will move on the fixed pipe 7. After the fixed block 806 moves, the slider 808 will slide inside the slideway of the fixed block 806, so that the sector block 801 contracts to fix the sleeve.

[0037] The working principle of the present utility model is as follows:

[0038] When the present utility model docks the sleeve, the sleeve can be placed into the fixed pipe 7, and then the adjusting knob 807 is rotated to make the threaded rod 805 rotate. After the threaded rod 805 rotates, it drives the fixed block 806 to move. The movement of the fixed block 806 causes the slider 808 to slide inside the slideway, making the adjusting rod 802 move against the elastic force of the spring 803, so that the sector block 801 contracts inwards. Multiple sets of sector blocks 801 contract to clamp the sleeve, thereby fixing the sleeve. Since the fixed pipes 7 on both sides are on the same horizontal line, the sleeves on both sides are automatically aligned. After that, the front of the sleeve can be welded. After the front welding of the sleeve is completed, the first motor 901 is started to drive the first rotating shaft 4 to rotate, thereby driving the sleeve fixed in the fixed pipe 7 to rotate. Then, the back of the sleeve can be quickly welded. If the welding angle of the sleeve needs to be changed, the second motor 11 can also be started to drive the fixed rod 6 to rotate, thereby changing the angle of the sleeve fixed in the fixed pipe 7, that is, changing the welding angle of the sleeve. When the welding is completed, by rotating the adjusting knob 807 in the reverse direction, the threaded rod 805 is driven to rotate, causing the slider 808 to slide back, thereby driving the adjusting rod 802 to move, which also drives the sector block 801 to expand outwards, so as to loosen the sleeve in the fixed pipe 7 and remove the sleeve.

[0039] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
