[0002] The fin heat exchanger is a highly efficient heat exchange device. During the heat exchange process, the heat medium (such as steam, hot water or thermal oil) flows through the tube, and the heat is transferred to the air flowing through the fins through the fins tightly wrapped around the tube to achieve the purpose of heating or cooling. During the processing of the heat exchanger fins, in order to provide stable support and adjust the working position, and facilitate precise control of the processing process, the heat exchanger fins can be placed on the top of the lifting platform for processing.
[0003] The existing lifting platform used for heat exchanger fin processing controls the movement of the movable seat to drive the rotating frame 1 and the rotating frame 2 to rotate, thereby controlling the lifting and lowering of the console. The movable seat is pressed down on the top of the base plate, which is prone to bending and deformation. At the same time, when the movable seat is pressed tightly against the top of the base plate, the friction between the movable seat and the base plate increases, affecting the movement of the movable seat. Therefore, improvement is needed. Utility Model Content

At the same time, when the movable seat is pressed tightly against the top of the base plate, the friction between the movable seat and the base plate increases, affecting the movement of the movable seat.
[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a lifting platform for processing heat exchanger fins, comprising a base plate, a support bar fixedly mounted at the central position of the top of the base plate, mounting bars symmetrically fixedly mounted on both sides of the top of the base plate on the support bar, a bidirectional screw rotatably mounted at the central position between the two sets of mounting bars, the bidirectional screw passing through the support bar and rotatably connected to the support bar, and movable seats symmetrically provided on the surfaces of the bidirectional screw located on both sides of the support bar;
[0006] The mounting bar is symmetrically and rotatably mounted with a rotating frame 1 on both sides, and the movable seat is symmetrically and rotatably mounted with a rotating frame 2 on both sides. The rotating frame 1 and the rotating frame 2 on the same side of the support bar are cross-rotatably connected. A table is rotatably mounted on the top end between the four groups of rotating frames 1 and the four groups of rotating frames 2, and the top end of the rotating frame 2 is slidably connected to the table end. Rectangular grooves are symmetrically provided at the central position on both sides of the table end, and a fixed clamping plate is provided inside the rectangular groove.

[0012] Compared with the prior art, the beneficial effects of the present invention are:
[0013] 1. The lifting platform for processing heat exchanger fins is provided with a bidirectional screw, a movable seat, a movable roller and a table, and controls the forward and reverse rotation of the rotating motor. The rotation of the rotating motor is transmitted to the bidirectional screw through the meshing of two sets of bevel gears, and the bidirectional screw is controlled to rotate forward and reverse, so that the movable seats on the two side surfaces of the bidirectional screw are moved closer to or away from each other, and the movable roller is driven to move on the top of the base plate, thereby supporting the movable seat while reducing the friction between the movable seat and the mounting frame when moving on the top of the base plate.

[0014] 2. The lifting platform for processing heat exchanger fins is provided with a concave retaining frame, a fixed protrusion, a fixed clamping plate and an elastic clamping pad. After the heat exchanger fin is placed on the top of the table, the concave retaining frame is flipped and pressed against the top of the table, and the fixed clamping plate is clamped on the surfaces of two sets of fixed protrusions on the same side of the two sets of concave retaining frames. Ensure that the fixed clamping plate is clamped into the corresponding rectangular groove and the gap between the two sets of concave retaining frames, so that the elastic clamping pad is squeezed and deformed in the gap between the rectangular groove and the two sets of concave retaining frames, thereby clamping the fixed clamping plate between the two sets of concave retaining frames, so that the concave retaining frame can cover the heat exchanger fin, and the heat exchanger fin is placed on the top of the table for processing and does not slide off at will.

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.
[0021] like Figure 1-4 As shown, the utility model provides a technical solution: a lifting platform for processing heat exchanger fins, comprising a base plate 1, a support bar 2 is fixedly installed at the central position of the top of the base plate 1, mounting bars 3 are symmetrically fixedly installed on both sides of the support bar 2 on the top of the base plate 1, a bidirectional screw 4 is rotatably installed at the central position between the two groups of mounting bars 3, and the bidirectional screw 4 passes through the support bar 2 and is rotatably connected to the support bar 2, and the bidirectional screw 4 is provided to control the rotation of the bidirectional screw 4, so that the moving seats 8 of the bidirectional screw 4 on both sides of the support bar 2 are synchronously moved closer to or away from each other;
[0022] One end of the bidirectional screw 4 passes through the support bar 2 and is fixedly installed with a bevel gear 5. A rotating motor 6 is fixedly installed on the top of the base plate 1 on one side of the support bar 2. A bevel gear 5 is fixedly installed on the output end of the rotating motor 6. The two sets of bevel gears 5 are meshed with each other. Because a rotating motor 6 and a bevel gear 5 are provided, the rotating motor 6 is controlled to rotate forward and reverse, and the forward and reverse rotation of the rotating motor 6 is transmitted to the bidirectional screw 4 through the meshing of the bevel gear 5, thereby controlling the bidirectional screw 4 to rotate forward and reverse, so that the moving seats 8 are moved closer to or away from each other on the surface of the bidirectional screw 4.
[0023] The bidirectional screw 4 is symmetrically provided with a moving seat 8 on the surface of both sides of the support bar 2; two groups of limiting slide bars 7 are symmetrically fixedly installed between the two ends of both sides of the support bar 2 and the two groups of mounting bars 3, and the two ends of the moving seat 8 are slidingly connected with the limiting slide bars 7. By providing the limiting slide bars 7, the moving seat 8 is controlled to move on the surface of the two groups of limiting slide bars 7 to ensure that the moving seat 8 will not tilt or deflect during the movement.
[0024] A mounting frame 9 is fixedly installed at the bottom of the movable seat 8, and two sets of mounting shafts 10 are symmetrically fixedly installed on the bottom of the mounting frame 9, and a moving roller 11 is rotatably installed on the surface of the mounting shaft 10. Because of the provision of the moving roller 11, the movable seat 8 drives the mounting frame 9 to move on the top of the base plate 1 when moving, so that the moving roller 11 rolls on the top of the base plate 1, thereby reducing the friction of the mounting frame 9 when moving on the top of the base plate 1, and at the same time supporting the movable seat 8 to prevent the movable seat 8 and the mounting frame 9 from falling and bending when moving on the top of the base plate 1.
[0025] A rotating frame 12 is symmetrically and rotatably installed on both sides of the mounting bar 3, and a rotating frame 2 13 is symmetrically and rotatably installed on both sides of the movable seat 8. The rotating frame 12 and the rotating frame 2 13 on the same side of the support bar 2 are cross-rotatably connected. A table 14 is rotatably installed at the top between the four groups of rotating frames 12 and the four groups of rotating frames 2 13, and the top of the rotating frame 2 13 is slidably connected to the table 14. By providing the rotating frame 12 and the rotating frame 2 13, when the movable seat 8 approaches the mounting bar 3, the rotating frame 2 13 and the rotating frame 12 are driven to rotate, thereby lifting the table 14 and adjusting the height of the table 14;
[0026] Concave retaining frames 16 are symmetrically rotatably installed on both sides of the top of the table 14, and fixed protrusions 17 are symmetrically fixed on one end of both sides of the concave retaining frames 16. Because of the concave retaining frames 16, when the two sets of concave retaining frames 16 are tightly fixed on the top of the table 14, it is ensured that when the heat exchanger fins are placed on the top of the table 14, the heat exchanger fins will not slide off at will on the top of the table 14.
[0027] Rectangular slots 15 are symmetrically positioned at the center of each side of the table 14, with fixed clips 18 positioned within them. Fixed clips 19 are positioned on either side of the fixed clips 18, aligning with and aligning with the fixed bumps 17. By inserting the fixed clips 18 between two adjacent sets of concave retaining frames 16, and engaging the fixed clips 19 with the corresponding fixed bumps 17, the two sets of concave retaining frames 16 are securely fixed to the top of the table 14.
[0028] Elastic clip pads 20 are fixedly installed on both sides of the fixed card plate 18. Because of the elastic clip pads 20, after the fixed card plate 18 is inserted into the corresponding rectangular groove 15, the elastic clip pads 20 are squeezed and deformed between the inner wall of the rectangular groove 15 and the fixed card plate 18, thereby clamping and fixing the fixed card plate 18 inside the rectangular groove 15, and clamping and fixing the two sets of concave retaining frames 16.
[0029] The working principle of this utility model is:
[0030] After pushing the heat exchanger fin to the center of the top of the platform 14, flip the two sets of concave retaining frames 16 and stick them to the top of the platform 14, then insert the fixed card 18 into the corresponding rectangular groove 15 and the gap between the two sets of concave retaining frames 16, so that the fixed card hole 19 is stuck on the surface of the fixed protrusion 17 on both sides of the two sets of concave retaining frames 16, control the rotation motor 6 to rotate, drive the bidirectional screw 4 to rotate, so that the moving seats 8 on both sides of the bidirectional screw 4 move toward the mounting bar 3 on the surface of the corresponding limit slide 7, and control the moving seat 8 to drive The mounting frame 9 moves on the top of the base plate 1, so that the moving seat 8 drives the rotating frame 2 13 and the rotating frame 1 12 to rotate. After the table 14 is lifted to a suitable height, the rotating motor 6 is stopped, so that the moving seat 8 is clamped and fixed on the surface of the bidirectional screw 4 and will not move at will. When the table 14 needs to be lowered, the rotating motor 6 is controlled to reverse, so that the moving seats 8 on both sides of the bidirectional screw 4 are away from the mounting strip 3, driving the rotating frame 2 13 and the rotating frame 1 12 to rotate, so that the height of the table 14 is gradually lowered and close to the top of the two groups of mounting strips 3.
