Description

Technical Field

[0001] This invention relates to the field of carriage processing equipment technology, specifically to a pre-processing device for the assembly of carriage panels. Background Technology

[0002] Sanding the truck bed panels removes irregularities or roughness, resulting in a smoother surface. This improves the fit and provides a better foundation for the subsequent assembly of multiple panels. Currently, the primary method for sanding truck bed panels is to lift them up and have workers use handheld sanders on both sides to sand the weld points. However, this method has the following problems:

[0003] 1. When the top of the truck bed is hoisted up for grinding, the lack of fixation at the bottom of the truck bed makes it easy for the truck bed to shift during grinding due to its uneven structure, which reduces the grinding accuracy and stability.

[0004] 2. The slag produced during grinding will be scattered everywhere, and may even adhere to the welding points of the carriage panel. Therefore, it is necessary to clean the surface of the carriage panel after grinding to ensure the stability of subsequent welding. However, cleaning alone reduces the processing efficiency of the carriage panel.

[0005] In summary, there is a need for a highly efficient and stable pretreatment device for grinding car body panels. Summary of the Invention

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0030] To address the technical problems in the background section, the following pre-processing device for the assembly of carriage panels is provided:

[0031] Combination Figures 1-7 As shown, the present invention provides a grinding device for weld points of car body panels, including a base plate 1. A support frame 5 is fixed on one side of the base plate 1. An extension plate 7 is provided through the support frame 5. A third pneumatic rod 6 is fixed on the side wall of the support frame 5. The telescopic end of the third pneumatic rod 6 is connected to the bottom surface of the extension plate 7. A hanging plate 8 is connected to the bottom surface of the extension plate 7 away from the support frame 5. Two claws 9 are connected to the bottom surface of the hanging plate 8. Side push components 2 are fixed on both sides of the base plate 1. A first grinding mechanism 3 is fixed on the top surface of the base plate 1. A second grinding mechanism 4 is attached to the top surface of the base plate 1. The first grinding mechanism 3 and the second grinding mechanism 4 have the same structure and are mirror images of each other. The two sets of side push components 2 are respectively connected to both sides of the second grinding mechanism 4.

[0032] The first grinding mechanism 3 includes a trough 31, a fixed grinding component 32, a second side plate 33, a second motor 34, a slag removal component 35, and a screw 36. The trough 31 is fixed to the top surface of the bottom plate 1. The second side plates 33 are fixed on both sides of the trough 31. The screw 36 is rotatably connected between the two second side plates 33. One end of the screw 36 passes through the second side plate 33 and is connected to the second motor 34. The second motor 34 is disposed on the side wall of the second side plate 33. The fixed grinding component 32 is sleeved on the outer wall of the screw 36. The fixed grinding component 32 is slidably connected to the top surface of the trough 31. The slag removal component 35 is connected to one side of the fixed grinding component 32 and is slidably disposed inside the trough 31.

[0033] The above structure can achieve the following effects: the top of the carriage panel 9a is clamped and lifted by the chuck 9, and then the second grinding mechanism 4 is pushed to the first grinding mechanism 3 by the side push assembly 2, so that the bottom of the carriage panel 9a is set between the first grinding mechanism 3 and the second grinding mechanism 4. Then, two sets of fixed grinding assemblies 32 are driven on both sides of the carriage panel 9a respectively, so that the fixed grinding assembly 32 moves and positions itself to the welding point position on the convex surface of the carriage panel 9a. Then, the concave surface of the carriage panel 9a is positioned and fixed. Then, the welding position on the convex surface of the carriage panel 9a is ground. During the grinding process, the slag removal assembly 35 is used to remove the slag generated during grinding, which improves the efficiency of grinding the welding point of the carriage panel 9a and ensures the stability of grinding.

[0034] In this embodiment, the grinding assembly 32 includes a slide 321, a first gear 322, a grinding component 323, and a positioning component 324. The slide 321 is slidably connected to the top side of the groove 31. A screw 36 is connected through the inside of the slide 321. The grinding component 323 is disposed through the inside of the slide 321. The first gear 322 is embedded in the top surface of the slide 321 and is rotatably connected to the inside of the slide 321. The positioning component 324 is disposed on the top surface of the slide 321. The first gear 322 is meshed between the grinding component 323 and the positioning component 324. The first gear 322 drives the positioning component 324 to flip and fit against the concave surface of the carriage plate 9a. A slag removal assembly 35 is fixed to the side wall of the slide 321.

[0035] By activating the grinding component 323 on the slide block 321 to move and grind the carriage panel 9a, the positioning component 324 is rotated and fitted to the concave surface of the carriage panel 9a by the first gear 322, thereby improving the efficiency of positioning and grinding the carriage panel 9a.

[0036] In this embodiment, the grinding component 323 includes a sliding plate 3231, a second fixed plate 3232, a second pneumatic rod 3233, a toothed plate 3234, a first fixed frame 3235, a first motor 3236, and a grinding disc 3237. The sliding plate 3231 and the toothed plate 3234 are arranged in parallel and are slidably inserted into the slide block 321. The second fixed plate 3232 is fixed between the sliding plate 3231 and the toothed plate 3234. A second pneumatic rod 3233 is connected to one side of the second fixed plate 3232 and is fixed to the side wall of the slide block 321. A first fixed frame 3235 is fixed to the side of the sliding plate 3231 and the toothed plate 3234 away from the second fixed plate 3232. The first fixed frame 3235 is provided inside the first fixed frame 3235. The rotating end of the first motor 3236 is connected to the grinding disc 3237. A first gear 322 is meshed with the top surface of the toothed plate 3234.

[0037] The second fixed plate 3232 is driven by the second pneumatic rod 3233, and the fixed frame is pushed by the sliding plate 3231 and the toothed plate 3234, so that the grinding disc 3237 grinds the carriage plate 9a, ensuring the stability of the grinding disc 3237 during movement and grinding.

[0038] In this embodiment, the positioning component 324 includes a second fixing frame 3241, a second gear 3242, a rotating rod 3243, a second flap 3246, and a positioning post 3247. The second fixing frame 3241 is fixed to the top surface of the slide block 321. The rotating rod 3243 is rotatably connected inside the second fixing frame 3241. The second gear 3242 is sleeved on the outer wall of the rotating rod 3243. The bottom of the second gear 3242 meshes with the first gear 322. The second flap 3246 is sleeved on the outer wall of the rotating rod 3243. There are two mirror images of the second flap 3246. The positioning post 3247 is fixed on the side of the second flap 3246 away from the rotating rod 3243. The outer end face of the positioning post 3247 has a chamfered structure.

[0039] The second gear 3242 drives the rotating rod 3243 to rotate inside the second fixed frame 3241. The rotating rod 3243 drives the second flip plate 3246 to flip, flipping the positioning post 3247 to the concave position of the carriage plate 9a. The chamfered structure of the positioning post 3247 makes it easier to flip and insert into the concave position of the carriage plate 9a, thereby achieving the positioning of the carriage plate 9a and ensuring the stability of grinding the carriage plate 9a.

[0040] In this embodiment, the positioning component 324 further includes a fixing bolt 3244 and a limiting plate 3245. The limiting plate 3245 is fixed to the outer wall of the rotating rod 3243. The second flap 3246 is slidably sleeved on the outer wall of the rotating rod 3243. The limiting plate 3245 is inserted into the inside of the second flap 3246. The fixing bolt 3244 is connected through the inside of the second flap 3246. The bottom end of the fixing bolt 3244 is attached to and clamped on the limiting plate 3245.

[0041] By sliding the second flap 3246 on the rotating rod 3243, the position and spacing of the two second flaps 3246 can be adjusted, so that the positioning post 3247 can be positioned and fitted more accurately on the concave surface of the carriage panel 9a. Then, the fixing bolt 3244 is rotated to position and fix the second flap 3246, which improves the flexibility of positioning the carriage panel 9a.

[0042] In this embodiment, the side-push assembly 2 includes a first pneumatic rod 21, a push plate 22, a first fixed plate 23, a first flip plate 24, a clamping plate 25, and a first side plate 26. The first side plate 26 is fixed to the side wall of the base plate 1. The first pneumatic rod 21 is fixed to the outer wall of the first side plate 26. The push plate 22 is connected to the telescopic end of the first pneumatic rod 21. The first fixed plate 23 is fixed to one side of the push plate 22. The first flip plate 24 is rotatably connected to the top of the first fixed plate 23. Two clamping plates 25 are fixed to one side of the first flip plate 24. Example 2

[0043] like Figures 5-7 As shown, based on the above embodiments, this embodiment further provides the following:

[0044] During the polishing process, the debris tends to disperse as it falls, reducing the effectiveness of debris removal. To solve this problem, the following structure is adopted.

[0045] The debris removal assembly 35 includes a bottom collection box 351, a third fixing plate 353, a third motor 354, and a fan blade 355. The third fixing plate 353 is fixed to the top surface of one side of the bottom collection box 351 and is fixed to the side wall of the slide 321. A first dust suction port 3511 is provided on the bottom side wall of the bottom collection box 351. The top surface of the bottom collection box 351 has a protruding structure and an air outlet 3515. The third motor 354 is provided on the top surface of the bottom collection box 351. The bottom end of the third motor 354 rotates through the interior of the bottom collection box 351 and is connected to the fan blade 355. A filter plate 3514 is fixed inside the bottom collection box 351 and is located at the bottom of the fan blade 355.

[0046] In this embodiment, a first partition 3512 is fixed to the bottom surface of the bottom collection box 351 near the first dust suction port 3511, and an inclined baffle 3513 is fixed to the side wall of the bottom collection box 351. The inclined baffle 3513 is spaced apart at the top of the first partition 3512. The bottom of the bottom collection box 351 is divided into a dust suction chamber and a dust collection chamber by the inclined baffle 3513 and the first partition 3512. The dust suction chamber is located on the side near the first dust suction port 3511.

[0047] The bottom collection box 351 is divided into a dust suction chamber and a dust collection chamber by a first partition 3512 and an inclined baffle 3513. This allows the grinding debris to be sucked into the bottom collection box 351 and then enter the dust collection chamber through the dust suction chamber. When the fan blades 355 are closed to remove the debris, the debris is stably collected into the dust collection chamber, thus ensuring the stability of the debris recycling.

[0048] In this embodiment, the debris removal assembly 35 further includes a side collection box 352, which is connected to the top of one side of the bottom collection box 351. A second dust suction port 3521 is provided on one side of the side collection box 352, and a second partition 3522 is fixed inside the side collection box 352.

[0049] By setting a side collection box 352 on the bottom collection box 351, the second dust suction port 3521 can be used to remove the debris from the grinding position, thereby further ensuring the cleaning effect of debris.

[0050] In this embodiment, a roller brush 3523 is rotatably connected to the side wall of the side receiving box 352, and two roller brushes 3523 are spaced apart.

[0051] When the moving debris removal component 35 moves to the next weld point grinding position, the roller brush 3523 on the side receiving box 352 cleans the weld point position of the freshly ground carriage panel 9a, thereby ensuring the cleanliness of the weld point position of the carriage panel 9a and further improving the stability of subsequent welding of the carriage panel 9a.

[0052] Working principle and usage process of this invention:

[0053] First press Figures 1-7 The top of the car body panel 9a is clamped onto the claw 9. Then, the third pneumatic rod 6 is activated to pull the extension plate 7 into the support frame 5 until the car body panel 9a is close to the first grinding mechanism 3. Then, the first flip plate 24 is flipped on the first fixed plate 23 to clamp the clamping plate 25 on both sides of the second grinding mechanism 4. The first pneumatic rod 21 is activated to push the push plate 22, so that the clamping plate 25 drives the second grinding mechanism 4 to slide on the base plate 1 and move towards the first grinding mechanism 3 until the car body panel 9a is positioned on both sides of the first grinding mechanism 3 and the second grinding mechanism 4.

[0054] Then, the second motors 34 of the first grinding mechanism 3 and the second grinding mechanism 4 are started respectively, driving the screw 36 to rotate on the second side plate 33. The screw 36 drives the slide block 321 to slide on the groove 31 until the grinding disc 3237 is moved to the convex surface position of the carriage plate 9a that needs to be ground. The spacing between the two positioning pins 3247 is adjusted according to the width of the concave surface adjacent to the convex surface position. By sliding the two second flaps 3246 on the rotating rod 3243, the outer end faces of the two positioning pins 3247 are aligned with the inner wall of the concave surface of the carriage plate 9a. Then, the fixing bolt 3244 is rotated to fix the second flaps 3246.

[0055] The second pneumatic rod 3233 is activated to pull the second fixed plate 3232. The slide plate 3231 and the toothed plate 3234 slide inside the slide block 321 and push the first fixed frame 3235. The first fixed frame 3235 drives the first motor 3236 to move until the grinding disc 3237 is in contact with the convex surface of the carriage plate 9a. At the same time, the toothed plate 3234 drives the first gear 322 to rotate during its movement. The first gear 322 meshes with the second gear 3242 for transmission. The rotating rod 3243 rotates inside the second fixed frame 3241. The second flip plate 3246 drives the positioning pin 3247 to flip and fit inside the concave surface of the carriage plate 9a, positioning the concave surfaces on both sides of the carriage plate 9a near the grinding position to ensure the stability of the grinding position of the carriage plate 9a.

[0056] The first motor 3236 is started, and the grinding disc 3237 grinds the welding points on the convex surface of the carriage panel 9a. At the same time, the third motor 354 is started to rotate the fan blade 355 to extract the air from the bottom collection box 351, creating a negative pressure inside the bottom collection box 351. The debris generated during grinding is sucked into the bottom collection box 351 through the first dust suction port 3511. Under the separation of the first partition 3512 and the inclined plate, the filter plate 3514 filters the debris into the bottom collection box 351. Some of the debris that is easy to float and disperse is drawn into the side collection box 352 through the second dust suction port 3521 on the side of the grinding disc 3237, and then enters the bottom collection box 351 through the side collection box 352.

[0057] Finally, the second pneumatic rod 3233 is activated to push the second fixed plate 3232, causing the grinding disc 3237 to separate from the carriage panel 9a. At the same time, the positioning pin 3247 is also flipped out from the concave surface of the carriage panel 9a. Then, the slide block 321 continues to move to prepare for grinding the next weld point. During the movement, the roller brush 3523 passes over the convex surface of the carriage panel 9a that has just been ground, sucking the remaining slag into the side collection box 352, completing the further cleaning of the ground area of ​​the carriage panel 9a.
