[0032] The technical solution of the present invention will be further described in detail below in conjunction with specific implementation methods.

[0033] like Figure 1 、 Figure 2 、 Figure 3 As shown, a positioning and clamping device for automobile parts processing includes a clamping mechanism 2, which is distributed and installed on a positioning plate 11. A plurality of groups of centering clamping grooves 110 are distributed in an annular manner on the positioning plate 11. Two groups of parallel clamping grooves 111 are also provided through the positioning plate 11, and the centering clamping grooves 110 and the parallel clamping grooves 111 are cross-arranged.

[0034] like Figure 5As shown, the clamping mechanism 2 includes a rotating screw 20, which is connected to the driving assembly 3.

A threaded sleeve 23 is meshedly installed on the rotating screw 20, and the threaded sleeve 23 is connected to a translation block 24. An elevating frame 27 is provided on the threaded sleeve 23, and a telescopic cylinder 28 parallel to the rotating screw 20 is horizontally installed on the elevating frame 27. The end of the telescopic cylinder 28 is telescopically connected to the clamping assembly.

[0035] like Figure 3 、 Figure 4 As shown, a receiving groove 112 is provided at the intersection of the centering clamping groove 110 and the parallel clamping groove 111, and a lifting frame 115 is installed in the receiving groove 112. A telescopic rotating motor 114 is provided at the bottom of the positioning plate 11, and the telescopic rotating motor 114 is connected to the lifting frame 115. The lifting frame 115 cooperates with the rotating screw 20, and the driving component 3 is connected to the power switching mechanism 4.

[0036] Specifically, the centering clamping grooves 110 are distributed in a ring. Driven by the driving component 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 components at the end are controlled by the lifting frame 27 and the telescopic cylinder 28 to achieve centering clamping of parts of various sizes.

[0037] More specifically, when the parts need to be clamped in parallel, the electromagnetic block is powered off and separated from the adsorption iron block, and the lifting frame 115 is controlled to rise by the telescopic rotating motor 114, so that the lifting frame 115 and the rotating screw 20 cooperate with each other, and then 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 controls the rotating screw 20 to fall into the parallel clamping groove 111. After the electromagnetic block is powered on again, it adsorbs the adsorption iron block in the parallel clamping groove 111, and is driven by the driving component 3 and the power switching mechanism 4 to drive the rotating screw 20 again, thereby controlling the clamping component to perform a parallel clamping operation.

[0038] Further, such as Figure 5 As shown, the clamping assembly includes a right-angle frame 29 arranged at the end of the telescopic cylinder 28, and a right-angle frame 210 is installed on the end of the right-angle frame 29 for lifting and sliding. A telescopic motor 211 is vertically arranged on the right-angle frame 29, and the telescopic motor 211 is connected to the right-angle frame 210.

[0039] Specifically, to further enhance centering and clamping capabilities for parts of varying sizes, a first right-angle bracket 29 and a second right-angle bracket 210 are installed at the ends of telescopic cylinder 28. Second right-angle bracket 210 is elevated and lowered by telescopic motor 211, enabling external centering clamping or outward splay positioning of parts as needed. The shape of the right-angle bracket can also be adjusted to meet part positioning and clamping requirements, thereby enhancing the clamping effect.

[0040] Further, such as Figure 5 、 Figure 6 、 Figure 7 As shown, the driving assembly 3 includes an annular frame 30 arranged on the outer ring of the positioning disk 11, and the inner ring of the annular frame 30 is provided with a clamping frame 36, and the clamping frame 36 is slidably clamped with the positioning disk 11. A follower frame 31 is provided on the annular frame 30, and a bevel gear ring 33 is provided on the follower frame 31. The end of the rotating screw 20 is coaxially connected with an extension rod 214, and a bevel gear 212 is provided on the extension rod 214. The bevel gear 212 and the bevel gear ring 33 are meshed with each other. The outer ring of the follower frame 31 is provided with an outer gear ring 32, and a power motor and a mating gear are fixedly provided on the edge of the positioning disk 11, and the mating gear is meshed with the outer gear ring 32.

[0041] Specifically, in order to synchronously control the evenly distributed rotating screw 20, the annular frame 30 is rotatably installed on the edge of the positioning plate 11, and the follower frame 31 on the annular frame 30 is driven to rotate in combination with the power motor and the matching gear, so that the bevel gear ring 33 and the bevel gear 212 are engaged with each other, and then the rotating screw 20 is synchronously controlled to rotate, thereby driving the clamping assembly to clamp the parts.

[0042] Further, such as Figure 5 、 Figure 7 、 Figure 8 、 Figure 9 As shown, the power switching mechanism 4 includes a follower frame 2 34 arranged at the bottom of the annular frame 30, and a bevel gear ring 2 35 is provided on the follower frame 2 34. A mounting plate 42 is provided at the bottom of the positioning disk 11, and a rotating shaft 1 41 is rotatably mounted on the mounting plate 42. The rotating shaft 1 41 is connected to the bevel gear 2 40, and the bevel gear 2 40 and the bevel gear ring 2 35 are engaged with each other. A right-angle frame 3 45 is provided at the bottom of the positioning disk 11, and a rotating shaft 2 44 is rotatably mounted on the right-angle frame 3 45. A spur gear 2 43 is provided at the end of the rotating shaft 2 44, and a spur gear 1 213 is provided at the end of the extension rod 214. A transmission pulley 411 is provided on the rotating shaft 1 41 and the rotating shaft 2 44, and a transmission belt 412 is installed between the transmission pulleys 411. A tensioning assembly is provided between the rotating shaft 1 41 and the rotating shaft 2 44.

[0043] Specifically, after the clamping mechanism 2 is adjusted from the centering clamping groove 110 to the parallel clamping groove 111, the power on the drive assembly 3 is re-transmitted to the rotating screw 20 through the power switching mechanism 4. After the rotating screw 20 is adjusted to the parallel clamping groove 111 under the drive of the telescopic rotating motor 114 and the lifting frame 115, the bevel gear 1 212 and the bevel gear ring 1 33 are disengaged. A follower frame 2 34 is provided at the bottom of the annular frame 30. The follower frame 2 34 is used to set the bevel gear ring 2 35 and the bevel gear 2 40. The power is transmitted to the rotating shaft 2 44 through the transmission pulley 411 and the transmission belt 412. After the rotating screw 20 is adjusted to the parallel clamping groove 111, the spur gear 1 213 at the end will mesh with the spur gear 2 43 at the end of the rotating shaft 2 44, realizing the re-docking of the power.

[0044] Further, such as Figure 9 As shown, the tensioning assembly includes a plug-in column 46 and a plug-in column 49 arranged at the bottom of the positioning plate 11. Two plug-in columns 46 and plug-in columns 49 are arranged in parallel. A lifting frame 48 is slidably installed on the two plug-in columns 49. A support spring 410 is sleeved on the plug-in column 49. A tensioning pulley 413 is rotatably installed on the lifting frame 48. The transmission belt 412 passes around the tensioning pulley 413. The right-angle frame 3 45 is plugged into the plug-in column 1 46. A lifting motor 1 47 is provided between the right-angle frame 3 45 and the positioning plate 11.

[0045] Specifically, in order to further ensure the reliable transmission of power, the rotating shaft 2 44 is lifted and installed through the plug-in column 1 46 and the lifting motor 1 47 to control the reliable engagement between the spur gear 1 213 and the spur gear 2 43. At the same time, a lifting frame 48 is installed at the bottom of the positioning plate 11, and a tensioning pulley 413 is installed in combination with the support spring 410 to ensure that the transmission belt 412 of the spur gear 2 43 can always transmit the power on the rotating shaft 1 41 to the rotating shaft 2 44 before and after adjustment, thereby realizing reliable transmission of power.

[0046] Further, such as Figure 10 、 Figure 11As shown, the center of the positioning disk 11 is hollowed out, and the center of the positioning disk 11 is lifted and installed with a centering placement component 5, and the centering placement component 5 includes a lifting motor 2 50, and the lifting motor 2 50 is fixedly installed on the base 1. An intermediate frame 10 is provided between the positioning disk 11 and the base 1, and the base 1 and the intermediate frame 10 and the positioning disk 11 are fixedly connected respectively. The lifting motor 2 50 is lifted and installed with a centering frame 51, and a cross slot 52 is provided on the centering frame 51, and a fixing frame 53 is provided at the center of the cross slot 52, and a fixing frame 53 is provided on the fixing frame 53. A driving motor 54 is provided, and the driving motor 54 is connected to a center gear 55. A limiting frame 57 is provided near the center of the cross slot 52, and a driving screw 58 is rotatably installed on the limiting frame 57. A driven gear 56 is provided at the position of the driving screw 58 near the center gear 55. The driven gear 56 and the center gear 55 are engaged with each other. A movable frame 59 is slidingly installed in the cross slot 52, and the movable frame 59 is threadedly engaged with the driving screw 58. A sleeve 510 is provided on the movable frame 59, and the sleeve 510 is sleeved on the outside of the driving screw 58.

[0047] Specifically, when centering and clamping an annular part, initial positioning can be performed using the centering assembly 5 installed in the center. A drive motor 54 drives the central gear 55 to rotate, synchronously driving the driven gear 56 in the cross slot 52 to rotate, thereby driving the drive screw 58 to rotate. The drive screw 58 controls the movable frame 59 to move back and forth within the cross slot 52, causing the sleeve 510 to move along with the movable frame 59, expanding from the inner circle outward, to perform initial centering and positioning of the annular part, and then cooperate with the clamping mechanism 2 to perform centering and clamping.

[0048] Furthermore, the end of the driving screw 58 is hemispherical, and the central gear 55 and the driven gear 56 are bevel gear matched.

[0049] Furthermore, the depth of the centering clamping groove 110 is greater than the depth of the parallel clamping groove 111, the mating block 1 21 and the mating block 2 22 are wedge-fitted with the adsorption iron block, and the bottom edges of the mating block 1 21 and the mating block 2 22 are provided with arc chamfers.

[0050] Specifically, the depth of the centering clamping groove 110 differs from the depth of the parallel clamping groove 111, making it easier to distinguish the location and clamping mode of the clamping mechanism 2. At the same time, to ensure the positioning and clamping effect and prevent the axial movement of the mating block 1 21 and the mating block 2 22, the mating block 1 21 and the mating block 2 22 form a wedge-shaped fit at the location where the iron block is attracted. At the same time, to facilitate the smooth switching of the mating block 1 21 and the mating block 2 22 between the centering clamping groove 110 and the parallel clamping groove 111, the bottom edges of the mating block 1 21 and the mating block 2 22 are provided with arc chamfers.

[0051] The working principle of the embodiment of the present invention is as follows: Figures 1-11As shown, the centering clamping grooves 110 are distributed in an annular pattern. Driven by the drive 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 lifting frame 27 and the telescopic cylinder 28 control the end clamping assembly to achieve centering clamping of parts of various sizes. When parallel clamping of parts is required, the electromagnetic block is powered off and the adsorption between the adsorption iron block is disengaged. The telescopic rotary motor 114 controls the lifting frame 115 to rise, so that the lifting frame 115 and the rotating screw 20 cooperate with each other. The telescopic rotary motor 114 then drives the lifting frame 115 and the rotating screw 20 to rotate above the parallel clamping groove 111, and then controls the rotating screw 20 to fall into the parallel clamping groove 111. When the electromagnetic block is powered again, it is attracted to the adsorption iron block in the parallel clamping groove 111. Driven by the drive assembly 3 and the power switching mechanism 4, the rotating screw 20 is driven again, thereby controlling the clamping assembly to perform parallel clamping operation. To further improve the centring clamping adaptability for parts of different sizes, a right-angle frame 1 29 and a right-angle frame 2 210 are respectively provided at the ends of the telescopic cylinder 28. The right-angle frame 210 is raised and lowered by the telescopic motor 211, and can be used to perform centring clamping or outward positioning of the parts as needed. The shape of the right-angle frame can also be adjusted according to the positioning and clamping requirements of the parts, thereby improving the clamping effect. To synchronously control the evenly distributed rotating screws 20, an annular frame 30 is rotatably mounted on the edge of the positioning plate 11. The power motor and the matching gear drive the follower frame 1 31 on the annular frame 30 to rotate, thereby causing the bevel gear ring 1 33 and the bevel gear 1 212 to engage with each other, thereby synchronously controlling the rotation of the rotating screw 20, thereby driving the clamping assembly to clamp the parts. After the clamping mechanism 2 is adjusted from the centring clamping groove 110 to the parallel clamping groove 111, the power switching mechanism 4 retransmits the power from the drive assembly 3 to the rotating screw 20. After the rotating screw 20 is adjusted to the parallel clamping groove 111 under the drive of the telescopic rotating motor 114 and the lifting frame 115, the bevel gear 1 212 and the bevel gear ring 1 33 are disengaged, and a follower frame 2 34 is set at the bottom of the annular frame 30. The follower frame 2 34 is used to set the bevel gear ring 2 35 and the bevel gear 2 40. The power is transmitted to the rotating shaft 2 44 through the transmission pulley 411 and the transmission belt 412. After the rotating screw 20 is adjusted to the parallel clamping groove 111, the spur gear 1 213 at the end will engage with the spur gear 2 43 at the end of the rotating shaft 2 44 to achieve power re-docking.To further ensure reliable power transmission, rotating shaft 2 44 is elevated and installed via plug-in column 1 46 and lifting motor 1 47, controlling the reliable meshing between spur gear 1 213 and spur gear 2 43. A lifting frame 48 is installed at the bottom of positioning plate 11, and a tensioning pulley 413 is installed in conjunction with a support spring 410. This ensures that the transmission belt 412 can always transmit the power from rotating shaft 1 41 to rotating shaft 2 44 before and after adjustment of spur gear 2 43, thereby achieving reliable power transmission. When centering and clamping annular parts, initial positioning can be achieved using the centering placement assembly 5 installed in the center. The drive motor 54 drives the center gear 55 to rotate, synchronously driving the driven gear 56 in the cross slot 52 to rotate, thereby driving the drive screw 58 to rotate. The drive screw 58 controls the movable frame 59 to move back and forth within the cross slot 52, causing the sleeve 510 to move along with the movable frame 59, expanding from the inner circle outward, to perform initial centering positioning of the annular part, and then cooperate with the clamping mechanism 2 to perform centering clamping.
