Specific embodiments

[0030] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments.

[0031] As Figure 1 , Figure 2 , Figure 3 shown, a positioning and clamping device for automotive part processing includes a clamping mechanism 2, the clamping mechanism 2 is distributively installed on a positioning disk 11, multiple groups of centering clamping grooves 110 are annularly distributed on the positioning disk 11, two groups of parallel clamping grooves 111 are also penetrated through the positioning disk 11, and the centering clamping grooves 110 and the parallel clamping grooves 111 are cross-set.

[0032] As Figure 5As shown, the clamping mechanism 2 includes a rotating screw 20, which is connected to a driving assembly 3. At both ends of the rotating screw 20, a first mating block 21 and a second mating block 22 are respectively arranged. Electromagnetic blocks are arranged in the first mating block 21 and the second mating block 22. Adsorbing iron blocks are arranged at positions corresponding to the first mating block 21 and the second mating block 22 in the centering clamping groove 110 and the parallel clamping groove 111. A threaded sleeve 23 is meshed and installed on the rotating screw 20. The threaded sleeve 23 is connected to a translation block 24. A lifting frame 27 is arranged on the threaded sleeve 23. A telescopic cylinder 28 parallel to the rotating screw 20 is horizontally installed on the lifting frame 27. The end of the telescopic cylinder 28 is telescopically connected to a clamping assembly.

[0033] As Figure 3 、 Figure 4 shown, a receiving groove 112 is arranged at the intersection of the centering clamping groove 110 and the parallel clamping groove 111. A lifting frame 115 is fitted and installed in the receiving groove 112. A telescopic rotary motor 114 is arranged at the bottom of the positioning disk 11. The telescopic rotary motor 114 is connected to the lifting frame 115. The lifting frame 115 cooperates with the rotating screw 20. The driving assembly 3 is connected to a power switching mechanism 4.

[0034] Specifically, the centering clamping grooves 110 are annularly distributed. Driven by the driving assembly 3, the rotating screw 20 is synchronously controlled to rotate, thereby driving the threaded sleeve 23 to move back and forth along the rotating screw 20. The clamping assembly at the end is controlled through the lifting frame 27 and the telescopic cylinder 28 to achieve centering clamping of parts of various sizes.

[0035] More specifically, when parallel clamping of the part is required, the electromagnetic block is powered off and separated from the adsorbing iron block. The lifting frame 115 is controlled to rise by the telescopic rotary motor 114, so that the lifting frame 115 cooperates with the rotating screw 20. Subsequently, the telescopic rotary motor 114 drives the lifting frame 115 and the rotating screw 20 to rotate above the parallel clamping groove 111, and then the rotating screw 20 is controlled to fall into the parallel clamping groove 111. After the electromagnetic block is re-powered on, it adsorbs with the adsorbing iron block in the parallel clamping groove 111. The rotating screw 20 is driven again under the drive of the driving assembly 3 and the power switching mechanism 4, so as to control the clamping assembly to perform parallel clamping operation.

[0036] Further, as Figure 5 shown, the clamping assembly includes a first right-angle frame 29 arranged at the end of the telescopic cylinder 28. A second right-angle frame 210 is installed at the end of the first right-angle frame 29 in a lifting and sliding manner. A second telescopic motor 211 is vertically arranged on the first right-angle frame 29. The second telescopic motor 211 is connected to the second right-angle frame 210.

[0037] Specifically, in order to further improve the centering clamping adaptability for parts of different sizes, a first right-angle frame 29 and a second right-angle frame 210 are respectively arranged at the end of the telescopic cylinder 28. The second right-angle frame 210 is installed to be lifted and lowered driven by the second telescopic motor 211, and can perform outer centering clamping or outward opening positioning on the part as needed. At the same time, the shape of the right-angle frame can be adjusted according to the positioning and clamping requirements of the part, so as to improve the clamping effect.

[0038] Further, as Figure 5 , Figure 6 , Figure 7 shown, the driving assembly 3 includes an annular frame 30 arranged on the outer circle of the positioning disk 11. A clamping frame 36 is arranged on the inner circle of the annular frame 30. The clamping frame 36 is slidably clamped with the positioning disk 11. A first follower frame 31 is arranged on the annular frame 30. A first bevel gear ring 33 is arranged on the first follower frame 31. The end of the rotating screw 20 is coaxially connected with an extension rod 214. A first bevel gear 212 is arranged on the extension rod 214. The first bevel gear 212 meshes with the first bevel gear ring 33. An external gear ring 32 is arranged on the outer circle of the first follower frame 31. A power motor and a mating gear are fixedly arranged on the edge of the positioning disk 11. The mating gear meshes with the external gear ring 32.

[0039] Specifically, in order to synchronously control the uniformly distributed rotating screws 20, the annular frame 30 is rotatably installed on the edge of the positioning disk 11. Combining the power motor and the mating gear drives the first follower frame 31 on the annular frame 30 to rotate, so that the first bevel gear ring 33 meshes with the first bevel gear 212, and further synchronously controls the rotating screw 20 to rotate, thereby driving the clamping assembly to clamp the part.

[0040] Further, as Figure 5 , Figure 7 , Figure 8 , Figure 9 shown, the power switching mechanism 4 includes a second follower frame 34 arranged at the bottom of the annular frame 30. A second bevel gear ring 35 is arranged on the second follower frame 34. An installation plate 42 is arranged at the bottom of the positioning disk 11. A first rotating shaft 41 is rotatably installed on the installation plate 42. The first rotating shaft 41 is connected with a second bevel gear 40. The second bevel gear 40 meshes with the second bevel gear ring 35. A third right-angle frame 45 is arranged at the bottom of the positioning disk 11. A second rotating shaft 44 is rotatably installed on the third right-angle frame 45. A second spur gear 43 is arranged at the end of the second rotating shaft 44. A first spur gear 213 is arranged at the end of the extension rod 214. Driving pulleys 411 are arranged on the first rotating shaft 41 and the second rotating shaft 44. A transmission belt 412 is installed between the driving pulleys 411. A tensioning assembly is arranged between the first rotating shaft 41 and the second rotating shaft 44.

[0041] Specifically, after the clamping mechanism 2 is adjusted from the centering clamping groove 110 to the parallel clamping groove 111, the power switching mechanism 4 re-transmits the power on the driving assembly 3 to the rotating screw 20. After the rotating screw 20 is adjusted to the parallel clamping groove 111 driven by the telescopic rotating motor 114 and the lifting bracket 115, the first bevel gear 212 is disengaged from the first bevel gear ring 33. A second follower frame 34 is provided at the bottom of the annular frame 30. The second bevel gear ring 35 and the second bevel gear 40 are arranged by using the second follower frame 34. The power is transmitted to the second rotating shaft 44 through the belt pulley 411 and the transmission belt 412. After the rotating screw 20 is adjusted to the parallel clamping groove 111, the first spur gear 213 at the end will mesh with the second spur gear 43 at the end of the second rotating shaft 44 to achieve the re-docking of the power.

[0042] Further, as Figure 9 shown, the tensioning assembly includes a first plug post 46 and a second plug post 49 provided at the bottom of the positioning disk 11. Two first plug posts 46 and second plug posts 49 are arranged in parallel. A lifting frame 48 is slidably mounted on the two second plug posts 49. A support spring 410 is sleeved on the second plug post 49. A tensioning belt pulley 413 is rotatably mounted on the lifting frame 48. The transmission belt 412 bypasses the tensioning belt pulley 413. The third right-angle frame 45 is inserted between the first plug post 46, and a first lifting motor 47 is provided between the third right-angle frame 45 and the positioning disk 11.

[0043] Specifically, in order to further ensure the reliable transmission of power, the second rotating shaft 44 is installed in a lifting manner through the first plug post 46 and the first lifting motor 47 to control the reliable meshing between the first spur gear 213 and the second spur gear 43. At the same time, the lifting frame 48 is installed at the bottom of the positioning disk 11, and the tensioning belt pulley 413 is installed in combination with the support spring 410 to ensure that the power on the first rotating shaft 41 can always be transmitted to the second rotating shaft 44 by the transmission belt 412 before and after adjustment of the second spur gear 43, so as to achieve the reliable transmission of power.

[0044] Further, as Figure 10 、 Figure 11As shown, the center of the positioning disc 11 is hollowed out, and a centering placement component 5 is installed in a lifting manner at the center of the positioning disc 11. The centering placement component 5 includes a second lifting motor 50, and the second lifting motor 50 is fixedly installed on the base 1. An intermediate frame 10 is provided between the positioning disc 11 and the base 1, and the base 1, the intermediate frame 10, and the positioning disc 11 are fixedly connected respectively. The second lifting motor 50 is installed in a lifting manner with a centering frame 51. A cross groove 52 is provided on the centering frame 51. A fixed frame 53 is provided at the center of the cross groove 52. A driving motor 54 is provided on the fixed frame 53. The driving motor 54 is connected with a central gear 55. A limiting frame 57 is provided near the center of the cross groove 52. A driving screw 58 is rotatably installed on the limiting frame 57. A driven gear 56 is provided at the part of the driving screw 58 near the central gear 55. The driven gear 56 meshes with the central gear 55. A moving frame 59 is slidably installed in the cross groove 52. The moving frame 59 is in threaded cooperation with the driving screw 58. A sleeve 510 is provided on the moving frame 59, and the sleeve 510 is sleeved outside the driving screw 58.

[0045] Specifically, when centering and clamping a ring-shaped part, preliminary positioning can be carried out through the centering placement component 5 installed at the center. The driving motor 54 is used to drive the central gear 55 to rotate, synchronously driving the driven gear 56 in the cross groove 52 to rotate, thereby driving the driving screw 58 to rotate. The driving screw 58 controls the moving frame 59 to move back and forth in the cross groove 52, so that the sleeve 510 moves along with the moving frame 59 and expands from the inner circle to the outside, performing preliminary centering positioning on the ring-shaped part, and then cooperating with the clamping mechanism 2 for centering and clamping.

[0046] Further, the end of the driving screw 58 is provided in a hemispherical shape, and the central gear 55 and the driven gear 56 are in a bevel gear fit.

[0047] Furthermore, the depth of the centering clamping groove 110 is greater than the depth of the parallel clamping groove 111. The first fitting block 21 and the second fitting block 22 are in a wedge fit with the adsorbed iron block, and arc chamfers are provided at the bottom edges of the first fitting block 21 and the second fitting block 22.

[0048] Specifically, there is a difference in the depth between the centering clamping groove 110 and the parallel clamping groove 111, which is convenient for distinguishing the location of the clamping mechanism 2 and the clamping mode. At the same time, in order to ensure the effect of positioning and clamping and prevent the first fitting block 21 and the second fitting block 22 from axially moving, a wedge-shaped fit is formed between the first fitting block 21 and the second fitting block 22 at the part where the iron block is adsorbed. At the same time, in order to facilitate the smooth switching of the first fitting block 21 and the second fitting block 22 between the centering clamping groove 110 and the parallel clamping groove 111, arc-shaped chamfers are provided at the bottom edges of the first fitting block 21 and the second fitting block 22.

[0049] The working principle of the embodiment of the present invention is as Figures 1 - 11As shown, the centering clamping grooves 110 are annularly distributed. Driven by the driving assembly 3, the rotating screw 20 is synchronously controlled to rotate, thereby driving the threaded sleeve 23 to move back and forth along the rotating screw 20. The clamping assembly at the end is controlled by the lifting frame 27 and the telescopic cylinder 28 to achieve centering clamping of parts of various sizes. When parallel clamping of the parts is required, the electromagnet is powered off and separated from the adsorbed iron block. The lifting frame 115 is lifted by the telescopic rotating motor 114, so that the lifting frame 115 cooperates with the rotating screw 20. Subsequently, the telescopic rotating motor 114 drives the lifting frame 115 and the rotating screw 20 to rotate above the parallel clamping groove 111, and then the rotating screw 20 is controlled to fall into the parallel clamping groove 111. After the electromagnet is re-energized, it adsorbs with the adsorbed iron block in the parallel clamping groove 111. The rotating screw 20 is driven again under the drive of the driving assembly 3 and the power switching mechanism 4, so as to control the clamping assembly to perform parallel clamping operation. In order to further improve the centering clamping adaptability for parts of different sizes, a first right-angle frame 29 and a second right-angle frame 210 are respectively arranged at the end of the telescopic cylinder 28. Among them, the second right-angle frame 210 is installed to move up and down under the drive of the second telescopic motor 211, and can perform outer centering clamping or outward expansion positioning on the parts according to needs. At the same time, the shape of the right-angle frame can be adjusted according to the positioning and clamping requirements of the parts, so as to improve the clamping effect. In order to synchronously control the uniformly distributed rotating screws 20, an annular frame 30 is rotatably installed at the edge of the positioning disk 11. The driving motor and the mating gear are combined to drive the follower frame 31 on the annular frame 30 to rotate, so that the first bevel gear ring 33 meshes with the first bevel gear 212, and then the rotating screw 20 is synchronously controlled to rotate, thereby driving the clamping assembly to clamp the parts. When the clamping mechanism 2 is adjusted from the centering clamping groove 110 into the parallel clamping groove 111, the power on the driving assembly 3 is re-transmitted to the rotating screw 20 through the power switching mechanism 4. After the rotating screw 20 is adjusted into the parallel clamping groove 111 under the drive of the telescopic rotating motor 114 and the lifting frame 115, the first bevel gear 212 is disengaged from the first bevel gear ring 33. A second follower frame 34 is arranged at the bottom of the annular frame 30. The second bevel gear ring 35 and the second bevel gear 40 are arranged by using the second follower frame 34. The power is transmitted to the second rotating shaft 44 through the belt pulley 411 and the transmission belt 412. After the rotating screw 20 is adjusted into the parallel clamping groove 111, the first spur gear 213 at the end will mesh with the second spur gear 43 at the end of the second rotating shaft 44 to realize the re-docking of power.To further ensure the reliable transmission of power, the second rotating shaft 44 is installed in a lifting manner through the first plugging column 46 and the first lifting motor 47 to control the reliable meshing between the first spur gear 213 and the second spur gear 43. Meanwhile, a lifting frame 48 is installed at the bottom of the positioning disk 11, and a tension pulley 413 is installed in combination with a support spring 410 to ensure that the power on the first rotating shaft 41 can always be transmitted to the second rotating shaft 44 through the transmission belt 412 before and after the adjustment of the second spur gear 43, thereby realizing the reliable transmission of power. When centering and clamping an annular part, preliminary positioning can be performed through a centering placement assembly 5 installed at the central part. The driving motor 54 is used to drive the central gear 55 to rotate, synchronously driving the driven gear 56 in the cross groove 52 to rotate, thereby driving the driving screw 58 to rotate. The driving screw 58 controls the movable frame 59 to move back and forth in the cross groove 52, so that the sleeve 510 moves along with the movable frame 59 and expands from the inner circle to the outside to perform preliminary centering positioning on the annular part, and then cooperate with the clamping mechanism 2 to perform centering clamping.
