Detailed Implementation

[0027] This invention discloses a heat exchange tube insertion device. The following describes one embodiment of the invention in detail with reference to the accompanying drawings.

[0028] Combination Figure 1 and Figure 2 As shown, a heat exchanger tube insertion device includes a feeding mechanism, a baffle fixing mechanism, and an end plate fixing mechanism. Several baffle fixing mechanisms are arranged in a staggered pattern and located between the feeding mechanism and the end plate fixing mechanisms. The feeding mechanism includes a frame 1, a drive assembly, and a conveying assembly. The drive assembly and the conveying assembly are both mounted on the frame 1. There are two conveying assemblies, symmetrically arranged on the left and right sides of the frame 1. Each conveying assembly includes a clamping part and several supporting parts. The clamping part and the supporting parts are mounted on the frame 1 via sliders and slide rails, allowing them to move up and down along the frame 1. The clamping part is located on the front side of the frame 1, and is fixedly connected to several supporting parts 10 via connecting rods 5 for synchronous movement.

[0029] like Figure 3As shown, the clamping part includes a connecting frame 2, an upper clamping member, and a lower clamping member. The upper and lower clamping members are arranged opposite to each other and are mounted on the connecting frame 2. The upper clamping member includes a first U-shaped plate 3, which is connected to the upper part of the connecting frame 2 via a slider and a slide rail, and can move up and down along the connecting frame 2. The opening of the first U-shaped plate 3 faces downward, and several rollers are rotatably connected to it. The lower clamping member includes a second U-shaped plate 4, which is fixedly connected to the lower part of the connecting frame 2. The opening of the second U-shaped plate 4 faces upward, and several rollers are rotatably connected to it. The supporting part includes a third U-shaped plate, which faces upward, and the top of its outer side is inclined inward. Rollers are rotatably connected to it. There are two drive assemblies, located on the front and rear sides of the frame 1, respectively. The drive assembly includes a drive motor and a second lead screw 6, which are connected in a transmission manner. The drive assembly located on the front side of the frame 1 has the nut slider of the second lead screw 6 fixedly connected to the connecting frame 2; the drive assembly located on the rear side of the frame 1 has the nut slider of the second lead screw 6 fixedly connected to the third U-shaped plate of the support part located on the rear side of the frame 1.

[0030] Combination Figure 4 , Figure 5 as well as Figure 6As shown, the baffle fixing mechanism includes a movable frame 7, a second support frame 9, and several first support frames 8. The bottom of the second support frame 9 is mounted on the top of the movable frame 7 via a slider and a slide rail. The bottoms of the several first support frames 8 are also mounted on the top of the movable frame 7 via sliders and slide rails. The several first support frames 8 are located on one side of the top of the movable frame 7, and the second support frames 9 are located on the other side of the top of the movable frame 7. A limiting plate 11 is fixedly connected to the rear top of the movable frame 7, and a U-shaped groove is provided on the limiting plate 11. Both the first support frames 8 and the second support frames 9 are triangular frame structures, and the rear sidewalls of the first support frames and the second support frames are perpendicular to the top surface of the movable frame 7. The second support frame 9 is provided with a support part 10 and several pressing parts. The bottom of the support part 10 is mounted on the top of the movable frame 7 via a slider and a slide rail, and the end of the support part 10 near the first support frame 8 is inclined. The support portion 10 has several elongated grooves on the side away from the first support frame 8. Limiting rods are disposed within these grooves and are fixedly connected to the second support frame 9. Nuts are threaded onto the ends of the limiting rods to secure the support portion 10 to the second support frame 9. A first clamping plate 18 is rotatably connected to the rear end of the support portion 10 near the first support frame 8, and a second clamping plate is fixedly connected to the front end. A locking pin 19 is provided on the rear side of the first support frame 8. The locking pin 19 includes a locking ring and a pin. The locking ring is fixedly connected to the first support frame 8, and the pin is L-shaped, with its upper part adapted to insert into the locking ring and move along the locking ring. The side of the upper part of the pin can contact the side of the first support frame 8 and the side of the first clamping plate 18.

[0031] Combination Figure 7 and Figure 8 As shown, the clamping part is mounted on the rear wall of the second support frame 9 via a clamping slider 13 and a clamping slide rail 12. The clamping part includes a pressure plate 14 and a pull lock. One side of the pressure plate 14 is rotatably connected to the clamping slider 13, and the other side has a notch. The notch is used to detachably connect the pressure plate 14 to the clamping slider 13 with a bolt. The pull lock is mounted on the pressure plate 14 and includes a handle 15, a pressure arm 16, and a pull arm. One end of the pressure arm 16 is rotatably connected to the pressure plate 14, and one end of the pull arm is also rotatably connected to the pressure plate 14. One side of the handle 15 is rotatably connected to the other end of the pressure arm 16, and the other side is rotatably connected to the other end of the pull arm. The end of the pressure arm 16 is slidably connected to a pressure rod 17 via a collar. The end of the pressure rod 17 is fixedly connected to a trapezoidal limiting block, which can be adapted to the mounting hole on the baffle plate.

[0032] Combination Figure 9 , Figure 10 as well as Figure 11As shown, the end plate fixing mechanism includes a fixing frame 20, a baffle 21, and two support blocks 22. The fixing frame 20 has a concave cross-section. The two support blocks 22 are respectively disposed on both sides of the top of the fixing frame 20, and both support blocks 22 are connected to the fixing frame 20 through a first lead screw 23, allowing them to move relative to the fixing frame 20. The first lead screw 23 is used to adjust the gap between the two support blocks 22. One end of the first lead screw 23 is connected to a handle, and the opposite end faces of the two support blocks 22 are both arc-shaped. The baffle 21 is fixedly connected to the front side of the fixing frame 20, and there is a gap between the baffle 21 and the support blocks 22.

[0033] The bottom of the frame 1 is provided with several first track wheels, each of which is arranged on a first track 24 and moves along the first track 24. The bottom of the movable frame 7 and the fixed frame 20 are both provided with several second track wheels, each of which is arranged on a second track 25 and moves along the second track 25, and the second track 25 is perpendicular to the first track 24.

[0034] In use, after the first track 24 and the second track 25 are laid perpendicularly, the feeding mechanism, the baffle fixing mechanism, and the end plate fixing mechanism can all move along the first track 24 and the second track 25 via the track wheels. The end plate fixing mechanism is located in front of the feeding mechanism, and several baffle fixing mechanisms are located between the end plate fixing mechanism and the feeding mechanism, and the baffle fixing mechanisms are staggered. The user places the baffle, which is in the shape of an arc, on the baffle fixing mechanism. The baffle has several mounting holes and several fixing holes that are compatible with the heat exchange tubes. The user places the bottom of the baffle in the U-shaped groove of the limiting plate 11, and then moves the first support frame 8 and the second support frame 9 to the rear of the baffle, and uses the rear side wall of the first support frame 8 to support the baffle and prevent the baffle from tipping over. The user moves the support part 10 closer to the baffle plate, causing the elongated groove to move relative to the limiting rod until the inclined end face of the support plate contacts the baffle plate. Then, the support part 10 is fixed to the second support frame 9 with a nut to prevent movement of the support part 10. The user rotates the first clamping plate 18 so that the baffle plate is positioned between the first clamping plate 18 and the second clamping plate. Then, the user pushes the pin upwards, causing the pin to move along the locking ring. The pin abuts the first clamping plate 18, preventing it from rotating and thus clamping the baffle plate. The user moves the pressing slider 13 along the pressing slide rail 12 until the position of the pressing part relative to the baffle plate is adjusted. Then, the user rotates the pressure plate 14, using the notch and bolt to fix it to the pressure plate 14. Finally, the user adjusts the position of the pressure rod 17 relative to the pressure arm 16 so that the limiting block is inserted into the mounting hole of the baffle plate. The handle 15, pull arm, pressure arm 16 and pressure plate 14 can form a four-bar locking structure. When the user presses down the handle 15, the baffle plate is fixed by the cooperation of the pressure rod 17 and the limit block, so as to prevent the baffle plate from tilting to the side.

[0035] The end plate is cylindrical and has several fixing holes adapted to the heat exchange tubes, and the edge of the opening has an outwardly extending protrusion. The user places the protrusion of the end plate between the baffle 21 and the fixing frame 20, and then rotates the first lead screw 23 by gripping the handle, so that the two support blocks 22 move towards each other, and the end faces of the two support blocks 22 are arc-shaped to adapt to the side wall of the end plate, thereby clamping and fixing the end plate and preventing the end plate from moving.

[0036] The user places the heat exchange tube on the lower clamping member and several supporting rollers, and then the upper clamping member clamps the heat exchange tube under the action of gravity. The user moves the first track wheel left and right along the first track 24 to adjust the position of the frame 1, and then starts the drive motor. The drive motor drives the second lead screw 6 to rotate, thereby causing the connecting frame 2 and each third U-shaped plate to move up and down along the frame 1, so that the heat exchange tube can be aligned with the fixing holes on the baffle plate and the fixing holes on the end plate. Then the user pushes the heat exchange tube to fit and insert it into the baffle plate and the end plate.

[0037] Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
