Description

Technical Field

[0001] This invention relates to the field of powder tanker truck frame welding technology, specifically to a large powder tanker truck frame positioning, welding, and turning equipment. Background Technology

[0002] The chassis frame of the powder tanker truck is used to support the entire weight of the vehicle body. The axle is installed on the lower side of the frame. The frame is welded together from multiple steel structural components during production. The joints on the upper and lower sides of the frame must be welded. Since the overall weight of the frame is several tons, it is very troublesome to flip and weld the chassis frame. Traditional flipping frames will cause the frame to shift after flipping, and long-term use will cause the expansion bolts on the flipping frame to loosen, which can easily lead to tipping and other situations, posing certain safety hazards. In addition, the existing flipping frames lack automated loading and unloading functions and require hoisting to move the frame, resulting in low work efficiency. Summary of the Invention

Detailed Implementation

[0027] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figure 1-9The large frame positioning, welding, and tilting equipment for powder tank trucks shown is used for frame welding. It includes a frame 1, a positioning and clamping mechanism 2, a rotary drive mechanism 3, a conveying mechanism 4, mounting rings 5, and a mounting frame 6. Two mounting rings 5 ​​are provided, coaxially positioned at both ends of the frame 1. The mounting frame 6 is horizontally positioned between the two mounting rings 5, with both ends fixedly connected to the two mounting rings 5. Several sets of positioning and clamping mechanisms 2 are provided, arranged sequentially along the length of the mounting frame 6. The rotary drive mechanism 3 includes two annular support frames 31, fixedly installed at both ends of the frame 1. The two mounting rings 5 ​​are rotatably mounted on the two annular support frames 31 via bearings. The conveying mechanism 4 includes several horizontally positioned conveying shafts 41, with the axis of the conveying shafts 41 perpendicular to the length of the mounting frame 6. The conveyor shafts 41 are divided into two groups, and the two groups of conveyor shafts 41 are located on both sides of the platform along the length direction. Several conveyor shafts 41 in each group are arranged sequentially along the length direction of the mounting frame 6. The conveying mechanism 4 is driven by several conveyor shafts 41. The positioning and clamping mechanism 2 includes a support frame 21, a telescopic rod 22, a clamping assembly 23 and a rotary transmission assembly 24. The support frame 21 is fixedly installed on the mounting frame 6, and the length direction of the support frame 21 is perpendicular to the length direction of the mounting frame 6. The telescopic rod 22 is horizontally arranged on the support frame 21, and the axial direction of the telescopic rod 22 is consistent with the length direction of the support frame 21. There are four sets of clamping assemblies 23, and the four sets of clamping assemblies 23 are respectively arranged on both sides of two I-shaped steels of the platform. The rotary transmission assembly 24 is fixedly installed on the support frame 21. The telescopic rod 22 is driven by the clamping assembly 23, and the rotary transmission assembly 24 drives the telescopic rod 22 to rotate.

[0029] During the welding of the powder tanker truck platform, two I-beams along the length of the platform are placed on the support frame 21 along the length of the mounting frame 6. A reinforcing rib is added between the two I-beams. First, the platform is clamped and positioned by the positioning clamping mechanism 2. Then, the operator performs the welding operation between the I-beams and the reinforcing rib, thus completing the platform welding operation. After the front of the platform is welded, the rotation drive mechanism 3 drives the mounting ring 5 to rotate. The mounting ring 5 drives the mounting frame 6, which is fixedly connected to it, to rotate synchronously. The mounting frame 6 then drives the entire platform clamped on it to follow the rotation. Synchronous flipping allows the platform to rotate around the axis of the mounting ring 5, facilitating welding operations on the back of the platform by the operator, thus realizing the welding function of the large platform. After welding is completed, the conveyor shaft 41 in the conveying mechanism 4 is moved to the bottom of the platform. At this time, the clamping component 23 releases its grip on the platform, and the conveyor shaft 41 moves upward to lift the entire platform upward, causing the platform to detach from the mounting frame 6. Then, the conveyor shaft 41 rotates, driving the entire platform to be transported along the length of the mounting frame 6 and discharged from the center hole of the mounting ring 5 on one side, thereby realizing the automatic unloading function of the platform.

[0030] This invention enables the welding of large frames for powder tank trucks, allowing for precise positioning and clamping of the frames. It also enables the frames to be rotated as a whole, facilitating welding on the reverse side of the frames. This improves the ease of welding I-beams for operators and allows for automatic unloading of the entire frame after welding, increasing automation and production efficiency.

[0031] Both ends of the support frame 21 are provided with horizontal limiting strips 211. The side walls of the two horizontal limiting strips 211 are respectively attached to the bottom ends of the side walls of the two I-shaped steel sections of the platform. The clamping assembly 23 includes a clamping plate 231, a horizontal limiting plate 232 and a horizontal limiting rod 233. The clamping plate 231 is vertically arranged. The side of the clamping plate 231 away from the I-shaped steel section is axially connected to the end of the telescopic rod 22. The clamping plate 231 is slidably connected to the support frame 21. The sliding direction of the clamping plate 231 is consistent with the length direction of the support frame 21. The horizontal limiting plates 232 are respectively fixedly installed at the upper and lower ends of the clamping plate 231. The horizontal limiting plates 232 are used to clamp the inner wall of the I-shaped steel section. The length direction of the horizontal limiting rod 233 is consistent with the length direction of the support frame 21. One end of the horizontal limiting rod 233 is fixedly connected to the side wall of the clamping plate 231, and the other end of the horizontal limiting rod 233 is slidably connected to the support frame 21.

[0032] The horizontal limiting bar 211 is used to limit the I-shaped steel when it is being fed, preventing the I-shaped steel from shifting position and affecting welding accuracy. When the clamping assembly 23 clamps the I-shaped steel, the telescopic rod 22 extends, causing the clamping plate 231, which is axially connected to it, to slide towards the side closer to the I-shaped steel, thereby clamping the I-shaped steel. The horizontal limiting plate 232 is used to clamp the I-shaped steel in the vertical direction, so that the platform will not shift during the flipping process. The horizontal limiting rod 233 is used to guide and limit the displacement of the clamping plate 231. The two clamping plates 231 respectively abut against the two side walls of the I-shaped steel to achieve the horizontal clamping effect of the I-shaped steel. The horizontal limiting plate 232 abuts against the upper and lower ends of the I-shaped steel to achieve the vertical clamping effect of the I-shaped steel.

[0033] The telescopic rod 22 includes a sleeve 221 and a rotating rod 222. One end of the sleeve 221 is axially connected to the clamping plate 231, and the other end of the sleeve 221 is slidably engaged with the end of the rotating rod 222. The positioning and clamping mechanism 2 also includes a first mounting seat 25 and a second mounting seat 26. The first mounting seat 25 and the second mounting seat 26 are both fixedly mounted on the support frame 21. The sleeve 221 is connected to the first mounting seat 25, and the rotating rod 222 is connected to the second mounting seat 26. The outer side wall of the sleeve 221 is provided with an external thread, and the inner side wall of the first mounting seat 25 is provided with an internal thread that mates with the sleeve 221. The sleeve 221 is provided with a limiting transmission strip 224 inside, and the outer side wall of the rotating rod 222 is provided with a horizontal limiting groove 223 that mates with the limiting transmission strip 224. The rotating rod 222 is connected to the rotary transmission assembly 24.

[0034] The horizontal limiting strip 211 can limit the position of the I-shaped steel being fed, preventing the I-shaped steel from shifting and causing a decrease in subsequent welding accuracy. After the telescopic rod 22 extends, the end of the telescopic rod 22 abuts against the clamping plate 231 and drives the clamping plate 231 to move towards the side wall of the I-shaped steel. The rotating rod 222 rotates under the drive of the rotary transmission assembly 24. When the rotating rod 222 rotates, it drives the sleeve 221 to rotate synchronously. When the sleeve 221 rotates, it achieves the function of horizontal displacement through the threaded engagement with the first mounting seat 25. With the cooperation of the horizontal limiting groove 223 and the limiting transmission strip 224, the sleeve 221 and the rotating rod 222 ensure that the sleeve 221 will not interfere with the rotary drive when moving horizontally.

[0035] The rotary transmission assembly 24 includes a second rotary driver 241, a rotating shaft 242, a first synchronous belt 243, a second drive gear 244, and a second driven gear 245. The second rotary driver 241 is fixedly mounted on one end of the support frame 21. The rotating shaft 242 is horizontally mounted on the support frame 21, and the axial direction of the rotating shaft 242 is consistent with the length direction of the support frame 21. The second drive gear 244 is fixedly connected to the output end of the second rotary driver 241. The second driven gear 245 is fixedly mounted on the rotating shaft 242, and the second drive gear 244 meshes with the second driven gear 245. One end of the first synchronous belt 243 is connected to the rotating shaft 242, and the other end of the first synchronous belt 243 is connected to the telescopic rod 22.

[0036] When the rotary transmission assembly 24 is working, the output of the second rotary driver 241 drives the second drive gear 244 to rotate. The second drive gear 244 drives the second driven gear 245 meshing with it to rotate, which in turn drives the rotating shaft 242 fixedly connected to the second driven gear 245 to rotate synchronously. The rotating shaft 242 drives the telescopic rod 22 to rotate through the first synchronous belt 243, thereby realizing the rotational drive function of the telescopic rod 22 and thus realizing the effect of driving the telescopic rod 22 to extend.

[0037] The rotary drive mechanism 3 also includes a first rotary driver 32, a first drive gear 33, and a first driven gear 34. The first rotary driver 32 is fixedly mounted on the side wall of the annular support frame 31. The first drive gear 33 is vertically mounted on the annular support frame 31 and is fixedly connected to the output end of the first rotary driver 32. The first driven gear 34 is fixedly mounted on the outer side wall of the mounting ring 5 and meshes with the first drive gear 34.

[0038] When the platform needs to be flipped, the first rotary driver 32 outputs to drive the first drive gear 33 to rotate. When the first drive gear 33 rotates, it drives the first driven gear 34 meshing with it to rotate. The first driven gear 34 drives the mounting ring 5 fixedly connected to it to rotate, thereby driving the mounting bracket 6 installed on the mounting ring 5 to rotate synchronously, thus realizing the rotation drive of the platform clamped on the mounting bracket 6.

[0039] The conveying mechanism 4 also includes a lifting assembly 42 and a conveying assembly 43. The lifting assembly 42 is horizontally fixed on the frame 1, and the conveying assembly 43 is installed on the output end of the lifting assembly 42. There are several conveying shafts 41. The several conveying shafts 41 are divided into two groups and respectively arranged on both sides of the frame 1. Several conveying shafts 41 in each group are sequentially installed on the output end of the conveying assembly 43 along the length direction of the mounting frame 6.

[0040] The lifting assembly 42 includes a lifting plate 421 and lifting cylinders 422. The lifting cylinders 422 are fixedly installed on the frame 1. There are four lifting cylinders 422. The lifting plate 421 is horizontally positioned directly above the frame 1. The four lifting cylinders 422 are located at the four ends of the lifting plate 421. The output end of the lifting cylinder 422 is fixedly connected to the bottom end of the lifting plate 421. The conveying assembly 43 is fixedly installed on the lifting plate 421.

[0041] When the conveyor shaft 41 needs to lift the platform upward, the four lifting cylinders 422 output synchronously to lift the lifting plate 421 horizontally upward, thereby driving the conveyor assembly 43 to move upward, and in turn driving the conveyor shaft 41 installed on the conveyor assembly 43 to rise synchronously.

[0042] The transmission assembly 43 includes a bidirectional lead screw slide 431, a mounting plate 432, a second synchronous belt 433, and a third rotary driver 434. Two bidirectional lead screw slides 431 are provided, located on opposite sides of the two mounting rings 5. Each bidirectional lead screw slide 431 has two sliders that move in opposite directions. The output direction of the bidirectional lead screw slide 431 is perpendicular to the length direction of the mounting frame 6. The mounting plate 432 is vertically positioned above the lifting plate 421. Both ends of the mounting plate 432 are fixedly connected to the sliders on the same side of the two bidirectional lead screw slides 431. The length direction of the mounting plate 432 is fixedly connected to the mounting frame 6. One end of the transmission shaft 41 is axially connected to the mounting plate 432. Several transmission shafts 41 are connected to the second synchronous belt 433. The third rotary driver 434 is fixedly installed at one end of the bidirectional lead screw slide 431 and is connected to the second synchronous belt 433.

[0043] When material needs to be unloaded, the output of the third rotary driver 434 drives the second synchronous belt 433 to rotate. The second synchronous belt 433 drives several transmission shafts 41 to rotate synchronously. The rotation of the transmission shafts 41 causes the platform to move horizontally along the length of the mounting frame 6. When the platform is flipped, the output of the bidirectional screw slide 431 drives the two sliders to move away from each other. Then, the mounting plate 432 drives the transmission shafts 41 to move away from the platform, thereby preventing the transmission shafts 41 from interfering with the rotation of the platform.

[0044] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
