[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; it is obvious that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0029] Example 1

[0030] Reference Figure 1-Figure 4 , a riveted refrigerated truck chassis assembly platform, comprising a side beam 1 and a bottom cross beam 2, a conveying assembly being provided on the top of the side beam 1, and positioning assemblies being provided on both sides of the top of the side beam 1;

[0031] The conveying component includes a conveying frame 3, the positioning component includes a slide beam 9, and a motor 4 is provided on one side of the side beam 1. The motor 4 is used to drive the conveying frame 3 to convey the material to the position. A servo electric cylinder 14 is provided on the top of the side beam 1. The servo electric cylinder 14 is used to drive the slide beam 9 to clamp and position the material.

[0032] Reference Figure 1-Figure 4 The number of conveying frames 3 is set to two, and a rotating shaft 5 is provided on both sides of the two conveying frames 3. A first sprocket 6 is provided on both sides of the outer wall of each rotating shaft 5. Every two first sprockets 6 are connected by a chain, and a fixed belt 7 is provided on one side of the two conveying frames 3. A moving block 8 is provided on one side of each fixed belt 7. The output end of the motor 4 and the outer wall of a rotating shaft 5 are fixedly connected to a second sprocket 15, and the two second sprockets 15 are connected by a chain. The number of slide beams 9 is set to two, and the two slide beams 9 are respectively located on both sides of the top of the side beam 1. The number of bottom beams 2 is set to multiple, and a plurality of servo electric cylinders 14 are provided on the top of the side beam 1, each servo electric cylinder 14 is respectively located on the corresponding bottom beam 2, and a plurality of movable plates 13 are provided on one side of the two slide beams 9. The plurality of servo electric cylinders 14 are respectively slidably connected to the corresponding servo electric cylinder 14, and a plurality of rollers 12 are provided at the bottom of the two slide beams 9. A slide groove 11 is opened on the side of the two slide beams 9 close to the conveying frame 3, and a clamping plate 10 is provided in the internal sliding connection of each slide groove 11.

[0033] The conveying assembly and the positioning assembly can accurately correct and clamp the material, and can be automatically conveyed. The specific operation method is: first, after placing the material on the moving block 8 of the conveying frame 3, start the motor 4, and the output end of the motor 4 drives a rotating shaft 5 to rotate through a chain, and the first sprockets 6 on both sides of the outer wall of the rotating shaft 5 rotate accordingly. Since every two first sprockets 6 are connected by a chain, the rotating shafts 5 on both sides of the two conveying frames 3 rotate synchronously, thereby driving the chain to operate (the chain is a prior art and is not drawn in the figure). Since the fixed belt 7 is located on the chain, the chain operation will drive the moving block 8 to move. At this time, after the material is placed on the moving block 8 of the conveying frame 3, the conveying frame 3 conveys the material to its place.

[0034] At the same time, multiple servo electric cylinders 14 on the top of the side beam 1 are started, and each servo electric cylinder 14 is located on the corresponding bottom cross beam 2, providing power and guidance for the movement of the slide beam 9. The two slide beams 9 are located on both sides of the top of the side beam 1. Under the action of the servo electric cylinder 14, the slide beam 9 approaches the direction of the material. As the slide beam 9 moves, the clamping plate 10 on the side of the slide beam 9 close to the conveying frame 3 also approaches the material. At this time, the slide beam 9 runs according to the set distance. When the clamping plate 10 contacts the material, it continues to move to clamp the material. When the conveyor is transporting, the clamping plate 10 slides in the slide groove 11. Due to the sliding The multiple rollers 12 at the bottom of the rail beam 9 can play a role of auxiliary support and friction reduction during the movement, ensuring that the slide beam 9 moves smoothly. The multiple moving plates 13 are slidingly connected to the servo electric cylinder 14 to further ensure the movement accuracy of the slide beam 9. Through the movement of the slide beam 9 and the action of the clamping plate 10, the material is accurately clamped and positioned. When the clamping force reaches the parameter set torque, the slide beam 9 stops and automatically maintains pressure. At this time, the operator can start working. When the work is completed, press the return button of the servo electric cylinder 14, the slide beam 9 will retreat to the limit and stop, and the position data will be reset, and the work is completed in one go.

[0035] The conveying assembly can quickly and accurately deliver materials to the designated position without manual handling, greatly saving time and labor costs, achieving efficient material transportation, and improving production continuity and speed. The positioning assembly can accurately correct and clamp the materials, and the servo electric cylinder 14 can accurately control the movement distance and clamping force of the slide beam 9 to ensure that the materials maintain the correct position during the assembly process. The clamping plate 10 slides in the slide groove 11 and cooperates with the slide beam 9 to accurately clamp and position the materials, thereby improving the accuracy and quality of assembly. The combination of the two greatly reduces manual operation, reduces labor intensity, and improves work comfort and safety.

[0036] Working principle: First, place the material on the moving block 8 of the conveying rack 3, start the motor 4, and the output end of the motor 4 drives a rotating shaft 5 to rotate through a chain, and the first sprockets 6 on both sides of the outer wall of the rotating shaft 5 rotate accordingly. Since every two first sprockets 6 are connected by a chain, the rotating shafts 5 on both sides of the two conveying racks 3 rotate synchronously, thereby driving the chain to operate (the chain is existing technology and is not shown in the figure). Since the fixed belt 7 is located on the chain, the operation of the chain will drive the moving block 8 to move. At this time, after the material is placed on the moving block 8 of the conveying rack 3, the conveying rack 3 will transport the material to its place.

[0037] At the same time, multiple servo electric cylinders 14 on the top of the side beam 1 are started, and each servo electric cylinder 14 is located on the corresponding bottom cross beam 2, providing power and guidance for the movement of the slide beam 9. The two slide beams 9 are located on both sides of the top of the side beam 1. Under the action of the servo electric cylinder 14, the slide beam 9 approaches the direction of the material. As the slide beam 9 moves, the clamping plate 10 on the side of the slide beam 9 close to the conveying frame 3 also approaches the material. At this time, the slide beam 9 runs according to the set distance. When the clamping plate 10 contacts the material, it continues to move to clamp the material. When the conveyor is transporting, the clamping plate 10 slides in the slide groove 11. Due to the sliding The multiple rollers 12 at the bottom of the rail beam 9 can play a role of auxiliary support and friction reduction during the movement, ensuring that the slide beam 9 moves smoothly. The multiple moving plates 13 are slidingly connected to the servo electric cylinder 14 to further ensure the movement accuracy of the slide beam 9. Through the movement of the slide beam 9 and the action of the clamping plate 10, the material is accurately clamped and positioned. When the clamping force reaches the parameter set torque, the slide beam 9 stops and automatically maintains pressure. At this time, the operator can start working. When the work is completed, press the return button of the servo electric cylinder 14, the slide beam 9 will retreat to the limit and stop, and the position data will be reset, and the work is completed in one go.

[0038] Example 2

[0039] Reference Figure 5-Figure 7 The difference between this embodiment and the first embodiment is that a fixed block 16 is provided on one side of the clamping plate 10, and a plurality of auxiliary blocks 17 are provided on one side of the fixed block 16. The top of the fixed block 16 is fixedly connected to an electric push rod 18, and the output end of the electric push rod 18 is fixedly connected to a support frame 19. Both ends of the bottom of the support frame 19 are provided with a first trapezoidal block 20, and a connecting frame 22 is provided on one side of each two auxiliary blocks 17. A second trapezoidal block 21 is provided on the side of the two connecting frames 22 close to the corresponding first trapezoidal block 20. The structure of each second trapezoidal block 21 is adapted to the structure of the corresponding first trapezoidal block 20. A protective pad 23 is provided on one side of the plurality of auxiliary blocks 17, and the material of the protective pad 23 is made of elastic material.

[0040] Since the side of the clamping plate 10 in contact with the material is provided with a pressure sensor (such as Figure 5 As shown, the pressure sensor here is existing technology and will not be described in detail here).

[0041] When the clamping plate 10 is worn after a long period of work, the auxiliary block 17 can play an auxiliary clamping role. The specific operation method is as follows: first, when the clamping plate 10 is worn after a long period of work, the pressure sensor will detect the change in clamping force. Wear will cause the clamping force to decrease. When the pressure sensor detects that the clamping force drops to a preset value, the corresponding electric push rod 18 will be activated. The output end of the electric push rod 18 pushes the support frame 19 to move downward, and the first trapezoidal blocks 20 at both ends of the bottom of the support frame 19 move downward accordingly. When the first trapezoidal block 20 contacts the corresponding second trapezoidal block 21, due to their structural adaptation, the first trapezoidal block 20 will push the second trapezoidal block 21 to move outward, and the second trapezoidal block 21 drives the connecting frame 22 to move. The connecting frame 22 pushes the auxiliary block 17 to extend outward, and the protective pad 23 on one side of the auxiliary block 17 contacts the material, playing an auxiliary clamping role. In this way, when the clamping plate 10 is worn and the clamping force is insufficient, the extension of the auxiliary block 17 can timely compensate for the loss of clamping force, ensuring that the material remains in a stable clamping state during the assembly process.

[0042] When the clamping plate 10 is worn, the auxiliary block 17 can be extended in time to perform auxiliary clamping to ensure that the material is always in a stable clamping state during the assembly process. This helps to ensure the accurate positioning and firm connection of the various components of the container chassis, thereby improving the assembly quality and reducing assembly deviations and quality problems caused by loose clamping. The auxiliary clamping effect of the auxiliary block 17 can reduce the workload of the clamping plate 10 and slow down the wear rate of the clamping plate 10, thereby extending the service life of the clamping plate 10 and the entire equipment and reducing equipment maintenance costs.

[0043] Working principle: First, when the clamping plate 10 is worn after working for a long time, the pressure sensor will detect the change of clamping force. Wear will cause the clamping force to decrease. When the pressure sensor detects that the clamping force has dropped to a preset value, the corresponding electric push rod 18 will be started. The output end of the electric push rod 18 pushes the support frame 19 to move downward, and the first trapezoidal blocks 20 at both ends of the bottom of the support frame 19 move downward accordingly. When the first trapezoidal block 20 contacts the corresponding second trapezoidal block 21, due to their structural adaptation, the first trapezoidal block 20 will push the second trapezoidal block 21 to move outward, and the second trapezoidal block 21 drives the connecting frame 22 to move, and the connecting frame 22 pushes the auxiliary block 17 to extend outward. The protective pad 23 on one side of the auxiliary block 17 contacts the material, playing a role of auxiliary clamping. In this way, when the clamping plate 10 is worn and the clamping force is insufficient, the extension of the auxiliary block 17 can make up for the loss of clamping force in time, ensuring that the material remains in a stable clamping state during the assembly process.

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
