Description

Technical Field

[0001] This invention relates to the field of automobile manufacturing technology, and more specifically to an intelligent flipping robot for chassis processing. Background Technology

[0002] In the field of automotive frame manufacturing, intelligent flipping robots are widely used, greatly improving the efficiency of frame processing and assembly, and playing an important role in realizing the automation and intelligent upgrading of production lines.

[0003] A smart flipping robot for vehicle frame processing typically includes a mechanical body, a drive system, a control system, and a dedicated gripping end effector. The mechanical body consists of a base, a rotating base, an upper arm, a lower arm, and a flipping wrist, enabling multi-degree-of-freedom spatial movement. The drive system provides power to each joint. The control system, as the core, coordinates the action logic of each component. The dedicated gripping end effector is customized according to the special structure of the vehicle frame longitudinal beam and integrates an adaptive clamping mechanism. All parts work together to complete automated tasks such as gripping, lifting, precise flipping, and placement of the vehicle frame, featuring high load capacity, high precision, and high reliability. However, the traditional working method described above still has the following shortcomings: 1. When flipping heavy-duty frames, traditional methods (such as overhead crane hoisting) rely on manual experience, resulting in poor positioning accuracy. Furthermore, the frames are prone to shaking, slippage, or even falling during the flipping process, posing a serious safety threat to equipment and personnel. At the same time, it is difficult to guarantee the docking accuracy of subsequent assembly stations. 2. Traditional fixtures are fixed for the longitudinal beam size of specific vehicle models and cannot flexibly adapt to frames of different thicknesses and widths. When the product is changed, the fixtures need to be replaced or significantly adjusted manually, which is time-consuming and labor-intensive, seriously affecting the production cycle and making it difficult to meet the needs of flexible production. 3. After being flipped into place, it usually relies on a single pin or mechanical stop for locking, lacking a multi-interlocking safety mechanism. Under long-term high-load operation, there is a potential risk of locking failure due to mechanical wear or accidental impact.

[0004] Therefore, the present invention provides an intelligent flipping robot for chassis processing. Summary of the Invention

A flipping motor is fixedly connected to the bottom of the flipping support arm. A fixing slot is opened in the middle of the flipping support arm.

[0011] Furthermore, an adjusting seat is fixedly connected to the bottom of the clamping base plate, a lateral fixing block is provided on the side of the adjusting seat, a first spring is provided on the side of the lateral fixing block, a first linkage groove is opened at the bottom of the lateral fixing block, a guide rod is provided below the adjusting seat, there are two guide rods, an adjusting screw is provided in the middle of the two guide rods, an adjusting nut is fixedly connected to the bottom of the adjusting screw, an adjusting base is provided on the lower side of the adjusting seat, a bottom linkage bar is provided in the middle of the adjusting base, and a bottom fixing block is provided at the top of the bottom linkage bar.

[0013] The technical effects and advantages of this invention are as follows: 1. This invention, through the synergistic effect of "lateral fixing block compressing the first spring" and "linkage mechanism driving the bottom fixing block to rise", can automatically adapt to the small dimensional deviations and deformations of the frame longitudinal beam, ensuring uniform distribution of clamping force and effectively avoiding local deformation of the frame or damage to the paint surface that may be caused by stress concentration. At the same time, this "one-time positioning and synchronous clamping" method, compared with the traditional method of manually adjusting the clamps one by one, shortens the clamping preparation time by several times and greatly improves the production cycle.

[0014] 2. Before the vehicle is flipped, the fixed post must be removed from the locking hole. During the removal process, the locking block will first release the fixation of the flipping guide rail. After the vehicle is flipped into place, the primary locking action is to drive the fixed post to insert into the locking hole. After the frame is fully in place, the locking latch automatically completes the final fixation under the action of the spring force. This fundamentally eliminates the possibility of accidental loosening or swinging back due to misoperation, equipment vibration, or other reasons during or after the flipping process, providing a high level of safety for operators and equipment.

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The intelligent flipping robot for frame processing involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Reference Figure 1 , Figure 2 and Figure 4This invention provides an intelligent flipping robot for vehicle frame processing. The main body 1 of the device has a support base plate 11 at its bottom, and a support arm base 12 is fixedly connected to the top of the support base plate 11. A first support arm 13 is provided on the top of the support arm base 12, and a second support arm 14 is provided at the end of the first support arm 13. A connecting seat 15 is provided at the end of the second support arm 14, and a flipping support arm 16 is fixedly connected to the side of the connecting seat 15. A positioning mechanism 2 is provided at the bottom of the flipping support arm 16, and a positioning base plate 21 is provided at the bottom of the positioning mechanism 2. Semi-circular gears 22 are fixedly connected to the top two sides of the positioning base plate 21. A clamping mechanism 3 is provided at the bottom of the semi-circular gears 22, and a clamping base plate 31 is provided at the top of the clamping mechanism 3. The clamping mechanism 3 fixes the longitudinal beam of the vehicle frame, thereby ensuring the stability of the subsequent vehicle frame flipping. The clamping mechanism 3 is located below the semi-circular gears 22, so that the vehicle frame rotates around the flipping axis 223, thereby reducing the space required for flipping.

[0029] Reference Figure 1 and Figure 2 The support base plate 11 has two clearance grooves 111 in the middle. The support block 112 is fixedly connected to the top of the support base plate 11. The bottom end of the first support arm 13 is movably connected to the support arm base 12. There are two first support arms 13. Two first cylinders 131 are provided in the middle of the first support arm 13. The ends of the first support arm 13 and the ends of the second support arm 14 are movably connected. The middle of the second support arm 14 is provided with a second cylinder 141. The top of the second support arm 14 is provided with a third cylinder 151. By adjusting the cylinders and the support arms, the clamping mechanism 3 can be adjusted. The support block 112 supports the frame.

[0030] Reference Figure 3 and Figure 4 The side of the flip arm 16 is fixedly connected to the connecting seat 15. There are two flip arms 16. A drive shaft 161 is provided in the middle of the flip arm 16. Drive gears 1611 are fixedly connected to both sides of the drive shaft 161. A flip motor 162 is fixedly connected to the bottom of the flip arm 16. A fixing slot 164 is opened in the middle of the flip arm 16. Two locking slots 211 are fixedly connected to the top of the positioning base plate 21. Two flip guide rails 221 are opened in the middle of the semi-circular gear 22. A locking hole 222 is opened on the inner side of the semi-circular gear 22. A flip shaft 223 is provided in the middle of the semi-circular gear 22. The drive gears 1611 on both sides are driven to rotate by the flip motor 162, which in turn drives the semi-circular gears 22 on both sides to rotate. The locking hole 222 is used to fix the flipped semi-circular gear 22 to prevent displacement and shaking.

[0031] Reference Figure 5 and Figure 6Two first limiting blocks 163 are fixedly connected to the side of the flip arm 16. A locking motor 1641 is provided inside the fixing slot 164. A locking screw 1642 is provided on the side of the locking motor 1641. A first fixing block 17 is provided inside the fixing slot 164. A fixing post 171 is provided on the side of the first fixing block 17. A locking block 18 is provided on the side of the first fixing block 17. A locking spring 181 is fixedly connected to the side of the locking block 18. A first slot 172 is opened at the top of the first fixing block 17. A locking block 1721 is provided inside the first slot 172. A second spring 1722 is provided in the middle of the locking block 1721. A second slot 173 is opened at the top of the first fixing block 17. A return block 1731 is provided inside the second slot 173. A drive block 174 is fixedly connected to the side of the first fixing block 17.

[0032] The locking motor 1641 drives the first fixing block 17 to move inside the fixing slot 164, thereby moving the fixing post 171. This, in turn, locks the semi-circular gear 22 in conjunction with the locking hole 222. After the frame is flipped, the locking block 18 locks the locking slot 211 to ensure the stability of the frame after flipping. At the same time, through the movement of the first fixing block 17 driven by the locking motor 1641, the locking block 1721 can drive the locking block 18 to release the locking slot 211. When the first fixing block 17 moves to the maximum position, the return block 1731 can push the locking block 1721 back into the first slot 172, thereby allowing the locking block 18 to return to its initial position under the action of the locking spring 181. Both the locking block 18 and the first fixing block 17 can work independently, ultimately achieving double fixation of the positioning base plate 21.

[0033] Reference Figure 3 and Figure 4 A first base 23 is provided in the middle of the positioning base plate 21. A first motor 231 is fixedly connected to the side of the first base 23. Two first bidirectional screws 232 are provided in the middle of the first base 23. A transverse base 24 is provided on both sides of the first base 23. A second bidirectional screw 241 is provided on the top of the transverse base 24. A second base 25 is fixedly connected to the middle of the transverse base 24. A second motor 251 is fixedly connected to the side of the second base 25. A longitudinal base 26 is provided on both sides of the second base 25. The top of the longitudinal base 26 is fixedly connected to the bottom of the clamping base plate 31.

[0034] Driven by the first bidirectional screw 232, the transverse bases 24 on both sides of the first base 23 move closer or further away synchronously, ensuring synchronous movement of both and preventing the center of gravity from shifting. The second bidirectional screw 241 drives the longitudinal bases 26 on both sides to move closer to the longitudinal beam of the frame, thereby completing the clamping operation of the frame.

[0035] Reference Figure 7 and Figure 8 An adjusting seat 32 is fixedly connected to the bottom of the clamping base plate 31. A lateral fixing block 33 is provided on the side of the adjusting seat 32. A first spring 332 is provided on the side of the lateral fixing block 33. A first linkage groove 331 is opened at the bottom of the lateral fixing block 33. A guide rod 321 is provided below the adjusting seat 32. There are two guide rods 321. An adjusting screw 322 is provided in the middle of the two guide rods 321. An adjusting nut 3221 is fixedly connected to the bottom of the adjusting screw 322. An adjusting base 36 is provided on the lower side of the adjusting seat 32. A bottom linkage bar 35 is provided in the middle of the adjusting base 36. A bottom fixing block 34 is provided at the top of the bottom linkage bar 35.

[0036] When the longitudinal base 26 approaches the longitudinal beam of the frame, the lateral fixing block 33 first contacts the side of the longitudinal beam. At the same time, the lateral fixing block 33 compresses the first spring 332 at the rear, and the bottom first linkage groove 331 drives the connecting column 353 to move towards the adjusting seat 32. By rotating the adjusting nut 3221, the distance between the bottom fixing block 34 and the top of the adjusting seat 32 can be adjusted to adapt to different frame specifications. During the adjustment process, the connecting column 353 is always inside the first linkage groove 331, thereby realizing the linkage between the two.

[0037] Reference Figure 9 , Figure 10 and Figure 11 The bottom fixing block 34 has four second limiting blocks 341 on its side, a second linkage groove 342 at its bottom, four first linkage grooves 351 in the middle of the bottom linkage bar 35, a second linkage column 352 in the middle of the first linkage groove 351, a connecting column 353 in the middle of the bottom linkage bar 35, two first limiting grooves 361 in the middle of the adjusting base 36, two guide holes 362 on the right side of the adjusting base 36, limiting holes 363 on the side of the guide holes 362, and an adjusting hole 364 in the middle of the two guide holes 362.

[0038] The movement of the connecting column 353 causes the bottom linkage bar 35 to move along the inside of the first limiting groove 361. The second linkage column 352 is located inside the second linkage groove 342 and can move upward through the drive of the first linkage groove 351, thereby causing the bottom fixing block 34 to move upward, and finally achieving the fixation of the bottom of the frame.

[0039] The working principle of this invention is as follows: The frame to be flipped is placed on two support blocks 112 on top of the support base plate 11. According to the size of the frame longitudinal beam, the adjusting nut 3221 at the bottom of the clamping mechanism 3 is rotated first. The nut drives the adjusting screw 322 connected to it, so that the adjusting base 36 moves and is adjusted to a position slightly larger than the thickness of the longitudinal beam. Then, the two arms are driven by three sets of cylinders to send the clamping mechanism 3 at the bottom of the positioning mechanism 2 into the space between the two longitudinal beams of the frame.

[0040] Next, the first motor 231 is started, driving the two first bidirectional screws 232 in the middle of the first base 23 to rotate, causing the transverse bases 24 on both sides of the first base 23 to move synchronously to the appropriate position. Then, the second motor 251 is started, driving the second bidirectional screw 241 to rotate, causing the longitudinal bases 26 on both sides of the second base 25 to move away from each other, thereby pushing the clamping mechanism 3 against the inner side of the frame longitudinal beam.

[0041] Under the push of the longitudinal base 26, the lateral fixing block 33 inside the clamping mechanism 3 first contacts the inner side of the longitudinal beam and begins to compress the first spring 332 at its rear. At the same time, the first linkage groove 331 at the bottom of the lateral fixing block 33 drives the connecting column 353 to move along the first limiting groove 361. The movement of the connecting column 353 causes the second linkage column 352 in the second linkage groove 342 to move along the first linkage groove 351. Under the limiting action of the second limiting block 341, the second linkage column 352 pushes the bottom fixing block 34 upward through the second linkage groove 342, so that it is close to the bottom surface of the longitudinal beam. As the longitudinal base 26 continues to move, the lateral fixing block 33 and the bottom fixing block 34 finally firmly fix the frame longitudinal beam. At this time, the second motor 251 stops working and the frame is completely fixed. By rotating the adjusting nut 3221, the adjusting screw 322 can be driven to move the adjusting base 36 up and down along the guide rod 321 to adapt to longitudinal beams of different sizes. During this process, the connecting column 353 always remains inside the first linkage groove 331.

[0042] When flipping is required, the locking motor 1641 is activated, driving the locking screw 1642, causing the fixing post 171 at the end of the first fixing block 17 to exit from the locking hole 222. The semi-circular gear 22 is then in the unlocked state. Next, the flipping motor 162 is activated, and the driving gears 1611 on both sides of the drive shaft 161 synchronously drive the semi-circular gear 22 to rotate around the flipping shaft 223. During the flipping process, the first limiting block 163 always slides inside the flipping guide rail 221. When the frame is flipped to the required angle, the locking motor 1641 is activated again, pushing the fixing post 171 into the locking hole 222, thereby completing the locking of the positioning mechanism 2.

[0043] After the frame is completely flipped, the locking latch 211 on the top of the positioning base plate 21 will insert into the fixing slot 164. Under the action of the locking spring 181, the locking latch 211 is locked in the fixing slot 164, thus completing the final fixation of the positioning mechanism 2. Finally, through the action of the cylinder and the support arm, the frame is placed back on top of the support block 112, thus completing the entire frame flipping operation.

[0044] During the process of the fixed post 171 exiting the locking hole 222, the locking block 1721 at the top of the first fixed block 17 will drive the locking block 18 to move backward synchronously, releasing the fixation of the flip guide rail 221. At this time, the fixed post 171 has not completely exited the locking hole 222. When the fixed post 171 has completely exited and the first fixed block 17 has not reached its maximum displacement, the locking block 1721 continues to drive the locking block 18 to move. When the first fixed block 17 moves to the limit position, the return block 1731 contacts the inner wall of the fixing slot 164, pushes the locking block 1721 to compress the second spring 1722, so that the locking block 1721 is completely retracted into the first slot 172. The locking block 18 then returns to the initial position under the action of the locking spring 181.
