Description

Technical Field

[0001] This utility model relates to the field of air conditioner flat roof frame assembly technology, and in particular to an air conditioner flat roof frame assembly device. Background Technology

[0002] As a structural component of air conditioning equipment, the assembly quality of the air conditioner's flat-top frame directly affects the air conditioner's performance and service life. The air conditioner's flat-top frame is connected into an integral frame structure through welding and riveting. In practical applications, the size, shape, and structure of the flat-top frame will vary depending on the model and specifications of the air conditioner.

[0003] These frames need to have sufficient strength and stability to support the various components inside the air conditioner, while also meeting the installation space requirements and air circulation needs of the air conditioner. The assembly process involves the positioning, fixing and connecting of parts, and each step needs to be precisely controlled to ensure the overall quality of the frame.

[0004] Existing assembly equipment uses pre-set fixed molds or positioning structures to assemble skeletons of specific specifications, which can, to a certain extent, ensure the accuracy and stability of the skeleton during assembly and avoid problems such as instability of the skeleton structure caused by inaccurate positioning during the assembly process.

[0005] However, because the molds or positioning structures of these devices are designed and manufactured according to a single specification, they lack flexibility and versatility and can only be adapted to crossbeams and longitudinal beams of specific sizes. When it is necessary to assemble skeletons of different specifications, these devices cannot be quickly adjusted to adapt to new size requirements, resulting in unusability or the need for large-scale modification of the devices. This not only increases production costs and time costs, but also seriously affects production efficiency. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides an air conditioner flat-top frame assembly device, which aims to improve the lack of flexibility and versatility of existing single-specification molds or positioning structures, which can only be adapted to crossbeams and longitudinal beams of specific sizes.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an air conditioner flat-top frame assembly device, comprising a processing table, wherein multiple locking strips are fixedly connected at equal intervals on the left and right sides of the top of the processing table, multiple crossbeams are placed on the top of each of the multiple locking strips, multiple longitudinal beams are fixedly connected inside the multiple crossbeams, and the same placement frame is fixedly connected to the bottom of each of the multiple crossbeams, multiple fixing blocks are fixedly connected to the top of the processing table, L-shaped rods are fixedly connected to the outside of each of the multiple fixing blocks, connecting rods are slidably connected to the outside of each of the multiple L-shaped rods, one end of each connecting rod is slidably connected to the outside of the L-shaped rod, and the other end is threadedly connected to an adjusting screw, a rotating rod is fixedly connected to the top of each of the multiple adjusting screws, a rubber pad is fixedly connected to the bottom of each of the multiple adjusting screws, and a height adjustment mechanism is provided at each of the four corners of the bottom of the processing table.

[0008] As a further description of the above technical solution:

[0009] The height adjustment mechanism includes multiple legs, which are fixedly connected to the four corners of the bottom of the processing table. Each leg has an internal mounting groove, and a threaded adjusting rod is threadedly connected to the bottom of the inner side of the mounting groove. A rotating column is rotatably connected to the bottom of the threaded adjusting rod, and a foot pad is fixedly connected to the bottom of the rotating column. Multiple adjusting grooves are equidistantly formed around the top of the threaded adjusting rod, and a limiting rod is rotatably connected inside the threaded adjusting rod. The top of the limiting rod is fixedly connected to the top of the inner side of the mounting groove.

[0010] As a further description of the above technical solution:

[0011] Each of the multiple legs is fixedly connected with a reinforcing rod, and all of the reinforcing rods are cylindrical in shape.

[0012] As a further description of the above technical solution:

[0013] A bracket is fixedly connected to the right side of the processing table, and a mounting plate is fixedly connected to the top of the bracket.

[0014] As a further description of the above technical solution:

[0015] The top of the mounting plate is fixedly connected to multiple angle adjustment brackets, and multiple supplementary lights are rotatably connected inside each of the multiple angle adjustment brackets.

[0016] As a further description of the above technical solution:

[0018] As a further description of the above technical solution:

[0019] Multiple limiting plates are fixedly connected to the top left and right ends of the processing table, and the multiple limiting plates are respectively attached to the left and right ends of multiple crossbeams.

[0020] As a further description of the above technical solution:

[0021] Limiting plates 2 are fixedly connected to the top left and right sides of the processing table, and multiple limiting plates 2 are respectively attached to the front and rear sides of multiple crossbeams.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the combination structure of the crossbeam and longitudinal beam is supported by the placement frame. The clamping strip initially positions the crossbeam, and the L-shaped rod and connecting rod are used to adjust the position. Rotating the rotating rod drives the adjusting screw, so that the rubber pad presses the frame. This achieves the effect of precise positioning and firm fixation of the air conditioner flat roof frame, ensuring the accurate relative position of the crossbeam and longitudinal beam, making it adaptable to different specifications of frames, effectively preventing displacement during subsequent processing, providing a stable foundation for welding and inspection processes, improving assembly quality and efficiency, and ensuring product quality.

[0024] 2. In this utility model, the processing table is supported by outriggers, and the threaded adjustment rod is rotated by a tool to move threadedly within the mounting groove, thereby driving the rotating column and foot pad to rise and fall. The limit rod restricts the displacement of the threaded adjustment rod, achieving the effect of precise and flexible adjustment of the processing table height. This allows the processing table to adapt to different working scenarios and can also adjust the height according to the operator's height and habits, improving work efficiency, increasing operational convenience, and optimizing the overall assembly work experience.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 3 and Figure 4 An embodiment of this utility model provides an air conditioner flat-top frame assembly device, including a processing table 1. Multiple clips 3 are fixedly connected at equal intervals on the left and right sides of the top of the processing table 1. Multiple crossbeams 4 are placed on the top of each of the multiple clips 3. Multiple longitudinal beams 5 are fixedly connected inside the multiple crossbeams 4. The same placement frame 6 is fixedly connected to the bottom of each of the multiple crossbeams 4. Multiple fixing blocks 7 are fixedly connected to the top of the processing table 1. L-shaped rods 8 are fixedly connected to the outside of each of the multiple fixing blocks 7. Connecting rods 9 are slidably connected to the outside of each of the multiple L-shaped rods 8. One end of each of the multiple connecting rods 9 is slidably connected to the outside of the L-shaped rods 8, and the other end is threadedly connected to an adjusting screw 10. Rotating rods 11 are fixedly connected to the top of each of the multiple adjusting screws 10. Rubber pads 12 are fixedly connected to the bottom of each of the multiple adjusting screws 10. Height adjustment mechanisms 2 are provided at the four corners of the bottom of the processing table 1.

[0034] Specifically, firstly, the placement rack 6 is placed on the processing table 1. The placement rack 6 is used to support and initially position the combined structure of the crossbeams 4 and longitudinal beams 5. Multiple crossbeams 4 are placed on the clamping strips 3, which are equidistantly fixed on the left and right sides of the top of the processing table 1. The clamping strips 3 serve to initially position the crossbeams 4, ensuring that the crossbeams 4 have an accurate position on the processing table 1. Since multiple longitudinal beams 5 are fixedly connected inside the crossbeams 4, further fixing and adjustment of the assembled skeleton is required to ensure its structural stability and dimensional accuracy. Multiple fixing blocks 7 fixedly connected to the top of the processing table 1 provide sliding tracks for the connecting rods 9, with L-shaped rods 8 fixedly connected to their exteriors. One end of each connecting rod 9 slides outside the L-shaped rod 8. By sliding the connecting rods 9 along the L-shaped rod 8, the position of the connecting rods 9 can be adjusted to adapt to the assembly requirements of skeletons of different sizes. After adjusting the position of the connecting rods 9, the rotating rod 11 is rotated. The rotating rod 11 is fixedly connected to the adjusting screw 10. Rotating the rotating rod 11 will drive the adjusting screw 10. As the adjusting screw 10 is threaded into one end of the connecting rod 9, it moves up and down within the connecting rod 9. The rubber pad 12, fixedly connected to the bottom of the adjusting screw 10, fully contacts the frame and applies pressure during the movement of the adjusting screw 10. When the adjusting screw 10 moves downwards, the rubber pad 12 gradually approaches the surface of the crossbeam 4 or longitudinal beam 5. Continuing to rotate the rotating rod 11 brings the rubber pad 12 into contact with the frame. Utilizing the friction and pressure of the rubber pad 12, the crossbeam 4 and longitudinal beam 5 are fixed in the appropriate position, preventing displacement during subsequent processing. By adjusting the position of the connecting rod 9 on the L-shaped rod 8, different specifications of air conditioning flat-top frames can be flexibly adapted. Using the adjusting screw 10 and rubber pad 12, the frame can be precisely positioned and firmly fixed, ensuring that the relative positions of the crossbeam 4 and longitudinal beam 5 meet design requirements. This provides a stable foundation for subsequent welding and inspection processes, guaranteeing the assembly quality and efficiency of the air conditioning flat-top frame.

[0035] Reference Figure 1 and Figure 5 The height adjustment mechanism 2 includes multiple support legs 201, which are fixedly connected to the four corners of the bottom of the processing table 1. The support legs 201 have mounting grooves 202 inside. The bottom of the inner side of the mounting groove 202 is threadedly connected to a threaded adjustment rod 203. The bottom end of the threaded adjustment rod 203 is rotatably connected to a rotating column 204. The bottom end of the rotating column 204 is fixedly connected to a foot pad 205. Multiple adjustment grooves 206 are equidistantly opened around the top of the threaded adjustment rod 203. The inside of the threaded adjustment rod 203 is rotatably connected to a limit rod 207. The top end of the limit rod 207 is fixedly connected to the top of the inner side of the mounting groove 202.

[0036] Specifically, when the height of the processing table 1 needs to be adjusted, multiple support legs 201 at the bottom of the processing table 1 are fixedly connected to the four corners of the bottom of the processing table 1, providing support for the processing table 1. Each support leg 201 has an installation groove 202 inside, and a threaded adjusting rod 203 is threadedly connected to the bottom of the inner side of the installation groove 202. By inserting a tool into the adjustment groove 206 equidistantly opened around the top of the threaded adjusting rod 203, the threaded adjusting rod 203 can be rotated. Since the threaded adjusting rod 203 is threadedly connected to the installation groove 202 of the support leg 201, when the threaded adjusting rod 203 rotates, it will move up and down along the thread of the installation groove 202. The bottom end of the threaded adjusting rod 203 is rotatably connected to a rotating column 204, and the bottom end of the rotating column 204 is fixedly connected to a foot pad 205. When the threaded adjusting rod 203 moves up and down, it drives the rotating column 204 and the foot pad 205 to move together. If the threaded adjusting rod 203 rotates upward, the processing table 1... The overall height decreases, and conversely, if the threaded adjusting rod 203 rotates downwards, the height of the processing table 1 will increase. During the rotation of the threaded adjusting rod 203, in order to prevent displacement other than rotation during its up-and-down movement, a limiting rod 207 is internally connected to the threaded adjusting rod 203. The top of the limiting rod 207 is fixedly connected to the top of the inner side of the mounting groove 202. The limiting rod 207 restricts the threaded adjusting rod 203 to move axially up and down within the mounting groove 202, preventing it from shaking or deviating, and ensuring the stability and accuracy of the adjustment process. By adjusting the threaded adjusting rods 203 on the four corner legs 201 synchronously or asynchronously, the height of the processing table 1 can be precisely adjusted to adapt to different working scenarios and the needs of operators, ensuring that the assembled air conditioner flat roof frame can be transferred smoothly, or the processing table 1 can be adjusted to a suitable height according to the height and working habits of the operators, improving work efficiency and operational convenience.

[0037] Reference Figure 1 , Figure 2 and Figure 3 A reinforcing rod 13 is fixedly connected between multiple support legs 201, and the multiple reinforcing rods 13 are all cylindrical in design; a bracket 14 is fixedly connected to the right side of the processing table 1, and a mounting plate 15 is fixedly connected to the top of the bracket 14; multiple angle adjustment frames 16 are fixedly connected to the top of the mounting plate 15, and multiple supplementary lights 17 are rotatably connected inside the multiple angle adjustment frames 16; two auxiliary support rods 18 are fixedly connected inside the bracket 14, and the top ends of the two auxiliary support rods 18 are fixedly connected to the front and rear sides of the bottom of the mounting plate 15 respectively; multiple limiting plates 19 are fixedly connected to the left and right ends of the top of the processing table 1, and the multiple limiting plates 19 are respectively attached to the left and right ends of the multiple crossbeams 4; multiple limiting plates 20 are fixedly connected to the left and right sides of the top of the processing table 1, and the multiple limiting plates 20 are respectively attached to the front and rear sides of the multiple crossbeams 4.

[0038] Specifically, the reinforcing rods 13, which are fixedly connected between the multiple outriggers 201, effectively enhance the structural stability of the entire device due to their cylindrical design. They can distribute the pressure on the outriggers 201, ensuring the overall stability of the device even during complex operations on the processing table 1. The bracket 14 on the right side of the processing table 1 and its top mounting plate 15 provide installation positions for the angle adjustment frame 16 and the supplementary light 17. The multiple angle adjustment frames 16 are rotatably connected to the multiple supplementary lights 17. During assembly, the operator can rotate the supplementary lights 17 to adjust the lighting angle as needed. When assembling, welding, or inspecting the crossbeams 4 and longitudinal beams 5 on the processing table 1, if some areas are not well lit, the supplementary lights 17 can be rotated to illuminate those areas, ensuring that the operator can clearly observe the work area and improving the accuracy and efficiency of assembly. The bracket 14 has two auxiliary support rods fixedly connected inside. 18. The top of each auxiliary support rod is fixed to the front and rear sides of the bottom of the mounting plate 15. The auxiliary support rod 18 and the bracket 14 jointly support the mounting plate 15. When the supplementary light 17 is working, the auxiliary support rod 18 can prevent the mounting plate 15 from shaking and ensure that the supplementary light 17 provides stable illumination. Multiple limiting plates 19 are fixedly connected to the left and right ends of the top of the processing table 1 and are respectively attached to the left and right ends of multiple crossbeams 4. Limiting plates 20 are fixedly connected to the left and right sides of the top and are respectively attached to the front and rear sides of multiple crossbeams 4. When the crossbeams 4 are placed on the processing table 1, these limiting plates 19 and 20 can accurately position the crossbeams 4. When the operator places the crossbeams 4 on the clip 3, the limiting plates 19 and 20 can ensure that the crossbeams 4 are accurately positioned on the processing table 1, avoid the crossbeams 4 from shifting during the assembly process, ensure the assembly accuracy of the crossbeams 4 and the longitudinal beams 5, and thus improve the assembly quality of the entire air conditioning flat roof frame.

[0039] Working principle: The placement frame 6 is used to support and initially position the combined structure of the crossbeams 4 and longitudinal beams 5. Multiple crossbeams 4 are placed on the clamping strips 3, which are equidistantly fixed on the left and right sides of the top of the processing table 1. The clamping strips 3 serve to initially position the crossbeams 4, ensuring that the crossbeams 4 have an accurate position on the processing table 1. Since multiple longitudinal beams 5 are fixedly connected inside the crossbeams 4, further fixing and adjustment of the assembled frame is required to ensure structural stability and dimensional accuracy. Multiple fixing blocks 7 fixedly connected to the top of the processing table 1 provide sliding tracks for the connecting rods 9, with their externally fixed L-shaped rods 8. One end of each connecting rod 9 slides outside the L-shaped rod 8. By sliding the connecting rods 9 along the L-shaped rod 8, the position of the connecting rods 9 can be adjusted to adapt to the assembly needs of frames of different sizes. After adjusting the position of the connecting rod 9, rotate the rotating rod 11. The rotating rod 11 is fixedly connected to the adjusting screw 10. Rotating the rotating rod 11 will drive the adjusting screw 10 to rotate. Since the adjusting screw 10 is threaded inside one end of the connecting rod 9, it will move up and down inside the connecting rod 9 as the adjusting screw 10 rotates. The rubber pad 12 fixedly connected to the bottom of the adjusting screw 10 will fully contact the skeleton and apply a certain pressure during the movement of the adjusting screw 10. When the adjusting screw 10 moves downward, the rubber pad 12 gradually approaches the surface of the crossbeam 4 or the longitudinal beam 5. Continue to rotate the rotating rod 11 to make the rubber pad 12 contact the skeleton. Utilize the friction and pressure of the rubber pad 12 to fix the crossbeam 4 and the longitudinal beam 5 in a suitable position to prevent them from shifting during subsequent processing.

[0040] Furthermore, multiple support legs 201 are fixedly connected to the four corners of the bottom of the processing table 1, providing support for the processing table 1. Each support leg 201 has an internal mounting groove 202. The bottom of the inner side of the mounting groove 202 is threadedly connected to a threaded adjusting rod 203. By inserting a tool into the adjusting groove 206 equidistantly opened around the top of the threaded adjusting rod 203, the threaded adjusting rod 203 can be rotated. Since the threaded adjusting rod 203 is threadedly connected to the mounting groove 202 of the support leg 201, when the threaded adjusting rod 203 rotates, it will move up and down along the thread of the mounting groove 202. The bottom end of the threaded adjusting rod 203 is rotatably connected to a rotating column 204, and the bottom end of the rotating column 204 is fixedly connected to a foot pad 205. When the threaded adjusting rod 203 moves up and down, it drives the rotating column 204 and the foot pad 205 to move together. If the threaded adjusting rod 203 rotates upward, the entire processing table 1 will descend. Conversely, if the threaded adjusting rod 203 rotates downward, the height of the processing table 1 will rise. During the rotation of the threaded adjusting rod 203, in order to prevent it from displacing other than rotating during its up and down movement, a limiting rod 207 is rotatably connected inside the threaded adjusting rod 203. The top end of the limiting rod 207 is fixedly connected to the top of the inner side of the mounting groove 202. The limiting rod 207 restricts the threaded adjusting rod 203 to move up and down axially within the mounting groove 202, avoiding wobbling or deviation, and ensuring the stability and accuracy of the adjustment process.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
