An angle detection component is arranged between the rotating frame 7 and the sliding block 6, and the angle detection component can be a combination of a grating and a grating angle displacement sensor. A rotating motor 11 is fixed inside the sliding block 6, and the rotating shaft of the rotating motor 11 is connected to the rotating frame 7. Cylinders 8 are relatively installed on the outer walls at both ends of the rotating frame 7, and clamping plates 9 are fixed to the telescopic ends of the cylinders 8. A plurality of evenly arranged clamping rods 10 are fixed to the opposite surfaces of the two clamping plates 9.

[0025] The driving mechanism includes a driving chamber 12 and a driving motor 13. The driving chamber 12 is opened inside the bottom end of the moving seat 3. The driving motor 13 is fixed to one end of the driving chamber 12. A transmission component 14 is arranged on the inner wall of the driving chamber 12. The output shaft of the driving motor 13 is connected to the input shaft of the transmission component 14. The output shaft of the transmission component 14 is connected to a moving gear 15 and an active bevel gear 17. A rack 16 is fixed to the inner wall of the bottom end of the moving groove 2. The moving gear 15 is meshed with the rack 16 for transmission.

[0026] The transmission assembly 14 includes a shell 20 fixed to the inner wall of the bottom end of the driving chamber 12 and a rotating ring 23 rotatably connected to the middle section of the shell 20, an active bevel gear 17 is fixed to the outer wall of the rotating ring 23, a driven bevel gear 18 is transmission-engaged on one side of the active bevel gear 17, and the driven bevel gear 18 is connected to a threaded rod 19, and a rotating rod 22 and a rotating block 21 are rotatably matched with the inner walls of both ends of the shell 20, one end of the rotating rod 22 is connected to the moving gear 15, and the rotating block 21 is connected to the transmission shaft of the driving motor 13, and a flower groove 24 is provided on the inner wall of the rotating ring 23 and the rotating rod 22, and a connecting rod 26 is longitudinally slidably connected to the inner wall of the rotating block 21, and a spline 25 that is limitedly matched with the flower groove 24 is fixed to one end of the connecting rod 26, and two electromagnets 27 are relatively arranged on the outer wall of one end of the connecting rod 26 and the inner wall of the rotating block 21.

[0027] The clamping rod 10 includes a connecting tube 35 and a telescopic rod 36. The connecting tube 35 is fixed to the outer wall of the bottom end of the clamping plate 9. The telescopic rod 36 is slidably fitted on the inner wall of the connecting tube 35. A clamping head 37 is fixed to the bottom end of the telescopic rod 36. A spring 38 is arranged inside the connecting tube 35. Both ends of the spring 38 are respectively connected to the connecting tube 35 and the telescopic rod 36.

[0028] When assembling the frame, first lift the steel to be welded and place it between the two groups of clamping rods 10, then the cylinder 8 pushes the clamping plates 9 closer to each other, and clamps the steel through the clamping rods 10. During the clamping process of the clamping rods 10, the clamping head 37 first contacts the surface of the steel, and at this time the clamping plate 9 continues to move, the telescopic rod 36 is compressed to contract toward the inside of the connecting tube 35, and the spring 38 is compressed. Since a plurality of clamping rods 10 are evenly fixed under the clamping plate 9, when the surface shape of the steel is not a plane, the contraction amplitude of the telescopic rods 36 in the clamping rods 10 at different positions is different, so that a plurality of clamping rods 10 can contact and clamp the surface of the steel; when the two fixing frames 4 are fixed with After the steel is lifted, since the position of the steel is not easy to accurately control during lifting, the clamping position of the clamping plate 9 on the steel is uncertain, and the length of the steel on both sides of the clamping plate 9 cannot be accurately controlled. It is necessary to adjust the lateral position of the two steels according to the position after clamping, and the driving motor 13 drives the moving gear 15 to rotate through the transmission assembly 14. Through the transmission of the moving gear 15 and the rack 16, the moving seat 3 slides in the moving groove 2 to change the position of the steel, so that the steel can be accurately aligned and then welded; when the combination of the two steels has a certain angle, the rotating motor 11 drives the rotating frame 7 to rotate, driving the steel to change the angle, so that the two steels are aligned. The two steels are tilted against each other, and then the moving seat 3 slides in the moving groove 2 to change the position of the steel so that the two steels are aligned; when the two steels are connected at 90 degrees or the welding position of the two steels is not the end of the steel, the driving motor 13 drives the active bevel gear 17 to rotate through the transmission component 14, and the active bevel gear 17 and the driven bevel gear 18 are engaged through the transmission, driving the threaded rod 19 to rotate, and the sliding block 6 rises along the lifting groove 5 to change the position of the steel so that the steel can be welded according to the design requirements; when the driving motor 13 drives the moving gear 15 to rotate through the transmission component 14, the two electromagnets 27 generate the same magnetic force, so that the connecting rod 26 pushes The movable spline 25 enters the flower groove 24 at one end of the rotating rod 22, and the driving motor 13 drives the rotating rod 22 connected to the moving gear 15 to rotate; when the driving motor 13 drives the active bevel gear 17 to rotate, the magnetic force of one of the electromagnets 27 changes, so that the connecting rod 26 is magnetically attracted and retracted into the rotating block 21, driving the spline 25 to enter the flower groove 24 inside the rotating ring 23. At this time, the driving motor 13 drives the rotating ring 23 to rotate, so that the active bevel gear 17 rotates. During the welding process, the telescopic plate arranged on the inner wall of the top of the moving groove 2 can close the top of the moving groove 2 to prevent the welding slag generated by welding from entering the moving groove 2 and affecting the movement of the moving seat 3.

[0029] By arranging the moving groove 2, the moving seat 3, the fixed frame 4, the lifting groove 5, the sliding block 6, the rotating frame 7, the threaded rod 19 and the driving mechanism, the angle and position of the steel material can be arbitrarily changed as needed, which is convenient for adjusting the steel material.

[0030] By setting the transmission assembly 14, when a driving motor 13 is set as a power source, the threaded rod 19 and the moving gear 15 can be driven to rotate respectively, thereby changing the position of the rotating frame 7, reducing the setting of the power source, and making the device more compact.

[0031] By providing the clamping rod 10, the portion for clamping the steel material can be changed according to the shape of the steel material, so that the device can firmly clamp steel materials of different shapes.

[0032] Embodiment 2: An assembly device for a bucket-shaped screen frame, such as Figure 1 , Figure 7 , Figure 8 As shown, in order to improve the stability of the device and facilitate transportation; this embodiment makes the following improvements on the basis of embodiment 1: cavities 28 are opened at both ends of the base 1, and the inner walls of both ends of the cavity 28 are rotatably connected with threaded rods 29, and the outer wall of the threaded rods 29 is threaded with a movable frame 30, and the inner wall of the cavity 28 is fixed with a connecting frame that limits the movable frame 30 to only move longitudinally, and the bottom end of the movable frame 30 is connected to a universal wheel 31, and the top of the threaded rod 29 is connected to a driven bevel gear 2 32, and the inner wall of the cavity 28 is fixed with a double-headed motor 33. The output shafts at both ends of the double-headed motor 33 are connected to the driving bevel gear 2 34, and the driving bevel gear 2 34 is in transmission meshing with the driven bevel gear 2 32. The base 1 is provided with a storage cavity 39 on both sides. The inner wall of the storage cavity 39 is rotatably connected to a stabilizing plate 40 through a rotating column 41. The outer wall of the top of the rotating column 41 is connected to a driven gear 42. One side of the driven gear 42 is in transmission meshing with a driving gear 43. One side of the driving bevel gear 2 34 is in transmission meshing with a driven bevel gear 3 44. The driven bevel gear 3 44 is connected to the driving gear 43 through a transmission shaft.

[0033] When the device needs to be moved, the double-headed motor 33 drives the active bevel gear 2 34 to rotate, and the threaded rod 2 29 rotates through the transmission meshing between the active bevel gear 2 34 and the driven bevel gear 2 32, driving the moving frame 30 to drive the universal wheel 31 to move down, prop up the device, and move the device through the universal wheel 31. At the same time, the active bevel gear 2 34 drives the driven bevel gear 3 44 to rotate, so that the active gear 43 rotates synchronously, and the driving gear 43 and the driven gear 42 are meshed to make the rotating column 41 drive the stabilizing plate 40 to rotate, and the stabilizing plate 40 is stored in the storage chamber 39, reducing the floor space of the device. When the device is parked for use, the double-headed motor 33 drives the active bevel gear 2 34 to reverse, retract the universal wheel 31, and at the same time, the stabilizing plate 40 is moved out of the storage chamber 39, increasing the support area of ​​the device and improving the stability of the device.

[0034] By providing the universal wheel 31, the storage cavity 39, the stabilizing plate 40 and the rotating column 41, the movement of the device is facilitated, and at the same time the supporting area of ​​the device is increased, thereby improving the stability of the placement of the device.
