Description

Technical Field

[0001] The present invention relates to the technical field of assembly platforms, and in particular to a lifting and turning mechanism of an assembly platform. Background Art

[0002] When assembling workpieces, one of the workpieces is generally fixed on an assembly table, and then the workpiece to be installed is assembled onto the workpiece on the assembly table. When it is necessary to assemble workpieces on multiple assembly surfaces of the workpiece, the position of the workpiece on the assembly table also needs to be adjusted to complete the assembly of the workpiece.

[0003] Since most of the existing assembly tables are fixed structures, it is difficult to adjust the position of the assembly table according to the size of the workpiece when assembling the workpiece, which increases the difficulty of assembly. At the same time, when assembling multiple parts on a workpiece, it is also necessary to adjust the clamping position of the workpiece, which affects the assembly accuracy of the workpiece. Especially for workpieces with high dimensional accuracy, high precision in fitting between the workpieces is required during assembly, and high protection requirements for parts are required throughout the entire process. However, in the actual assembly process, if assembly is performed solely by pressure, the microscopic surface of the workpiece may become stuck during assembly due to microscopic unevenness, making it difficult for the assembly surfaces of the two workpieces to fit completely together and a gap will exist. This gap will cause the workpiece to accelerate wear or produce scratches during the force process, making it difficult to ensure installation accuracy. Summary of the Invention

DETAILED DESCRIPTION

[0058] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0059] like Figures 1 to 8 As shown, this embodiment proposes a lifting and flipping mechanism for an assembly table, including a lifting frame 1, a mounting platform 2 is slidably installed on the lifting frame 1, an assembly platform 3 is arranged on the upper part of the mounting platform 2, and also includes guide rods 4, a supporting frame 5, a vibration assembly, a height adjustment assembly and a flip adjustment assembly. Four guide rods 4 are symmetrically and fixedly installed on the lifting frame 1, the guide rods 4 are slidably matched with the mounting platform 2, the supporting frame 5 is arranged at the bottom of the assembly platform 3, and a rotation adjustment assembly is arranged between the supporting frame 5 and the assembly platform 3. The rotation adjustment assembly is used to control the assembly platform 3 to rotate, and the rotation adjustment assembly includes a rotating cylinder 6, a worm gear 7, a worm 8 and a first driving motor 9. The rotating cylinder 6 is rotatably installed on the supporting frame 5, and a worm gear 7 is coaxially fixedly installed on the rotating cylinder 6. A worm 8 is rotatably installed inside the supporting frame 5, and the worm 8 is meshed with the worm gear 7. The first driving motor 9 is fixedly installed inside the supporting frame 5, and the output end of the first driving motor 9 is fixedly connected to the worm 8.

[0060] Specifically, during operation, the workpiece is placed on the assembly platform 3, and then the workpiece is fixed. The workpiece can be lifted to the specified position through the setting of the installation platform 2, the adjusting screw 32 and the adjusting nut 33 and the supporting driving equipment. At this time, the assembly operation can be started. When the height position of the workpiece needs to be changed, the height adjustment component can be turned on to further adjust the height of the assembly platform 3. At the same time, the circumferential position of the flip adjustment component can also be adjusted. When the angular position of the workpiece needs to be changed, the flip adjustment component is turned on to adjust the angular position of the carrier 5, thereby adjusting the angular position of the assembly platform 3 to facilitate the assembly operation of the workpiece. During the operation, the vibration component is turned on, and the vibration component causes the workpiece to vibrate, so that during the assembly process, the microscopic matching deviation between the workpieces is reduced through vibration, thereby reducing stress concentration and improving the quality of assembly. At the same time, vibration can also reduce the resistance of the workpiece during the assembly process, making the assembly operation more convenient.

[0061] During assembly, if it is necessary to assemble different positions of the clamped workpiece, the circumferential position of the workpiece also needs to be adjusted. At this time, the first drive motor 9 is turned on, and the first drive motor 9 drives the worm 8 to rotate. The worm 8 can drive the worm wheel 7 to rotate, thereby driving the rotating cylinder 6 to rotate. Through the setting of the vibration component, the assembly platform 3 can be driven to rotate, thereby adjusting the rotation angle of the assembly platform 3 to facilitate the assembly of the workpiece.

[0062] like Figures 5 to 8As shown, the vibration component is installed at the bottom of the carrier 5 and is used to control the vibration of the workpiece installed on the assembly platform 3. The vibration component includes a connecting tube 10, a vibration motor 11, a first sensor 12 and a vibration isolation part. The connecting tube 10 is fixedly installed at the bottom of the assembly platform 3, and the connecting tube 10 is coaxially arranged with the rotating tube 6. The vibration motor 11 is fixedly installed inside the connecting tube 10, and the first sensor 12 is fixedly installed on the inner bottom wall of the carrier 5. The output end of the first sensor 12 is coaxially fixedly connected to the bottom of the connecting tube 10 through an elastic coupling. The vibration isolation part is installed between the rotating tube 6 and the connecting tube 10 to reduce the impact of vibration on the overall mechanism during assembly.

[0063] Specifically, when the rotating cylinder 6 rotates, the vibration isolation part can drive the connecting cylinder 10 to rotate, thereby synchronously rotating the assembly platform 3. When the workpiece needs to be vibrated, the vibration motor 11 is turned on to make the workpiece vibrate, thereby reducing the microscopic matching deviation between the workpieces through vibration, thereby reducing stress concentration and improving the quality of assembly. When adjusting the assembly platform 3 to rotate, the vibration motor 11 is in a closed state, and the role of the vibration isolation part is to reduce the impact of vibration on the overall mechanism. In the process of adjusting the rotation of the assembly platform 3, the first sensor 12 is in a standby state. In the process of rotating the assembly platform 3, the first sensor 12 does not act. The first sensor 12 can determine the rotation angle of the assembly platform 3 through the rotation angle of the output end.

[0064] The above, such as Figures 5 to 8 As shown, the vibration isolation portion includes a buffer mounting cylinder 13, a groove 14 and a protrusion 15. The buffer mounting cylinder 13 is coaxially fixedly installed between the rotating cylinder 6 and the connecting cylinder 10, wherein the buffer mounting cylinder 13 is made of a flexible material (such as rubber). The top of the rotating cylinder 6 and the bottom of the connecting cylinder 10 corresponding to the buffer mounting cylinder 13 are provided with a plurality of grooves 14 at equal angles in a circumferential shape. The corresponding positions of the top of the buffer mounting cylinder 13 and the connecting cylinder 10 and the corresponding positions of the bottom of the buffer mounting cylinder 13 and the rotating cylinder 6 are Positions are provided with a number of protrusions 15 at equal angles in a circular shape, and the protrusions 15 correspond to and fit with the grooves 14 one by one, wherein an annular groove 16 is provided on the inner side of the rotating cylinder 6 and the inner side of the buffer mounting cylinder 13, and a mounting ring 17 is provided on the outer side of the connecting cylinder 10 and the outer side of the buffer mounting cylinder 13, the annular groove 16 on the inner side of the rotating cylinder 6 matches the mounting ring 17 on the outer side of the buffer mounting cylinder 13, and the annular groove 16 on the inner side of the buffer mounting cylinder 13 matches the mounting ring 17 on the outer side of the connecting cylinder 10.

[0065] Specifically, as the rotating cylinder 6 rotates, the buffer mounting cylinder 13 is driven to rotate, and the buffer mounting cylinder 13 can be synchronously driven to rotate through the setting of the groove 14, so that the protrusion 15 on the top of the buffer mounting cylinder 13 and the groove 14 at the bottom of the connecting cylinder 10 are adapted to drive the connecting cylinder 10 to rotate. When vibration occurs, the vibration can be eliminated through the setting of the buffer mounting cylinder 13, thereby improving the overall anti-vibration effect of the mechanism, thereby reducing the impact of vibration on the mechanism as a whole. The cooperation of the groove 14 and the protrusion 15 facilitates more precise adjustment of the rotation of the assembly platform 3. The setting of the annular groove 16 and the mounting ring 17 improves the tightness of the installation between the buffer mounting cylinder 13 and the rotating cylinder 6 and the connecting cylinder 10, thereby improving the stability during operation.

[0066] like Figure 3 、 Figure 4 As shown, the height adjustment component is installed on the mounting platform 2 and is used to adjust the height position of the assembly platform 3. The height adjustment component includes a fixed frame 18, an inner sleeve 19, an outer sleeve 20, a first driving member 21 and a driving part. The fixed frame 18 is fixedly mounted on the mounting platform 2, the outer sleeve 20 is rotatably mounted between the fixed frame 18 and the mounting platform 2, the inner sleeve 19 is slidably mounted inside the outer sleeve 20, the first driving member 21 is fixedly mounted on the inner bottom wall of the fixed frame 18, and the output end of the first driving member 21 is coaxially rotatably connected to the inner top wall of the inner sleeve 19. The driving part is installed inside the fixed frame 18 and is used to drive the inner sleeve 19 to rotate.

[0067] Specifically, when adjusting the height of the assembly platform 3, the first driving member 21 is turned on, and the first driving member 21 can push the inner sleeve 19 to move inside the outer sleeve 20, thereby adjusting the height position of the assembly platform 3. When the circumferential position of the assembly platform 3 needs to be adjusted, the driving part is turned on, and the driving part can drive the outer sleeve 20 to rotate, thereby driving the inner sleeve 19 to rotate, and driving the assembly platform 3 to rotate around the axis of the inner sleeve 19, thereby adjusting the circumferential position of the assembly platform 3.

[0068] The above, such as Figure 3 、 Figure 4 As shown, the driving part includes a second driving motor 22, a second sensor 24 and a gear ring 25. The second driving motor 22 is fixedly installed inside the fixed frame 18. The output end of the second driving motor 22 is fixedly installed with a driving gear 23. The second sensor 24 is fixedly installed at the bottom of the fixed frame 18. The output end of the second sensor 24 is coaxial with the driving gear 23 and fixedly connected. The outer sleeve 20 is coaxially fixedly installed with a gear ring 25, and the gear ring 25 is engaged with the driving gear 23.

[0069] Specifically, when the outer sleeve 20 is driven to rotate, the second driving motor 22 is turned on, and the second driving motor 22 can drive the driving gear 23 to rotate, thereby driving the gear ring 25 to rotate, and the outer sleeve 20 to rotate. By setting the second sensor 24 and rotating the driving gear 23, the angle of rotation of the gear ring 25 can be determined, thereby determining the angle of rotation of the assembly platform 3 with the axis of the inner sleeve 19 as the center, which is convenient for adjusting the position of the workpiece.

[0070] like Figure 3 、 Figure 4 As shown, a flip adjustment assembly is installed on the height adjustment assembly for adjusting the angle of the assembly platform 3. The flip adjustment assembly includes a bracket 26, a swing frame 27, a third drive motor 28 and a third sensor 29. The bracket 26 is fixedly mounted on the top of the inner sleeve 19. The swing frame 27 is rotatably mounted on the bracket 26. The swing frame 27 is fixedly connected to the supporting frame 5. The third drive motor 28 is fixedly mounted on the bracket 26. The output end of the third drive motor 28 is coaxially fixedly connected to the rotation center of the swing frame 27. The third sensor 29 is fixedly mounted on the bracket 26. The output end of the third sensor 29 is coaxially fixedly connected to the rotation center of the swing frame 27.

[0071] Specifically, when adjusting the flipping angle of the assembly platform 3, the third driving motor 28 is turned on, and the third driving motor 28 drives the swing frame 27 to rotate on the bracket 26. The swing frame 27 adjusts the flipping angle of the assembly platform 3 through the setting of the supporting frame 5. The angle of rotation of the swing frame 27 can be determined by the setting of the third sensor 29, which is convenient for adjusting the position of the workpiece.

[0072] Among them, the first sensor 12, the second sensor 24 and the third sensor 29 are preferably incremental encoders. The incremental encoder is generally composed of a rotating optical disc and a group of photoelectric sensors. It works by sensing the relative displacement of the object. That is, when the optical disc rotates, the sensor will detect different light spots on the optical disc and generate a series of pulse signals. The number of these pulse signals is proportional to the rotation angle of the optical disc, so that the displacement of the object can be calculated. Taking the swing frame 27 as an example, when the swing frame 27 rotates a certain angle, the swing frame 27 will drive the optical disc of the incremental encoder to rotate. When the corresponding sensor detects that the light spot changes, a pulse is generated, and the rotation angle of the swing frame 27 is obtained by calculating the number of pulses. This is an existing technology and will not be elaborated here.

[0073] like Figure 5As shown, in order to clamp the workpiece and fix the position of the workpiece and the assembly platform 3, a second driving member 30 and a clamping plate 31 are also included. Two second driving members 30 are symmetrically and fixedly installed on the assembly platform 3, and the output ends of the two second driving members 30 are fixedly installed with clamping plates 31. When fixing the workpiece on the assembly platform 3, the two second driving members 30 are synchronously turned on, thereby simultaneously pushing the corresponding clamping plates 31 to move until the clamping plates 31 fix the workpiece, and the assembly operation can begin.

[0074] like Figure 3 As shown, in order to adjust the height of the mounting platform 2, it also includes an adjusting screw 32 and an adjusting nut 33. The lifting frame 1 is rotatably installed with an adjusting screw 32, and the adjusting screw 32 is threadedly sleeved with an adjusting nut 33. The adjusting nut 33 is fixedly connected to the mounting platform 2. There are two adjusting screws 32, and the two adjusting screws 32 are symmetrically arranged. Before the specific operation, two driving devices need to be set separately. Through the linkage of the two driving devices, the two adjusting nuts 33 are synchronously driven to rotate, so that the mounting platform 2 can be driven to move by the setting of the adjusting nut 33.

[0075] Among them, in order to prevent external impurities from entering the position where the adjusting screw 32 and the adjusting nut 33 are matched, causing the adjusting nut 33 and the adjusting screw 32 to be stuck, a telescopic protective cover can also be provided on the lifting frame 1. During installation, a telescopic protective cover is provided at both ends of the adjusting screw 32. One end of the telescopic protective cover is fixedly mounted on the lifting frame 1, and the other end is fixedly mounted on the mounting platform 2. When the mounting platform 2 moves along the guide rod 4, the two telescopic protective covers are both telescopic, thereby preventing external impurities from invading the adjusting screw 32 and the adjusting nut 33, and does not affect the normal movement of the mounting platform 2.

[0076] The working principle or usage process of this application is as follows:

[0077] First, place the workpiece on the assembly platform 3, and then simultaneously start the two second driving members 30, thereby simultaneously pushing the corresponding clamping plates 31 to move until the clamping plates 31 fix the workpiece. Then, through the setting of the installation platform 2, the adjusting screw 32 and the adjusting nut 33 and the matching driving equipment, the workpiece can be lifted to the specified position, and the assembly operation can be started at this time.

[0078] When the height position of the workpiece needs to be changed, the first driving member 21 is turned on, and the first driving member 21 can push the inner sleeve 19 to move inside the outer sleeve 20, thereby adjusting the height position of the assembly platform 3. When the circumferential position of the assembly platform 3 needs to be adjusted, the second driving motor 22 is turned on, and the second driving motor 22 can drive the driving gear 23 to rotate, thereby driving the gear ring 25 to rotate, thereby driving the outer sleeve 20 to rotate, thereby driving the inner sleeve 19 to rotate, thereby driving the assembly platform 3 to rotate around the axis of the inner sleeve 19, thereby adjusting the circumferential position of the assembly platform 3. Through the setting of the second sensor 24, through the rotation of the driving gear 23, the angle of rotation of the gear ring 25 can be determined, thereby determining the angle of rotation of the assembly platform 3 around the axis of the inner sleeve 19, which is convenient for adjusting the position of the workpiece.

[0079] When the flipping angle position of the workpiece needs to be changed, the third driving motor 28 is turned on. The third driving motor 28 drives the swing frame 27 to rotate on the bracket 26. The swing frame 27 adjusts the flipping angle of the assembly platform 3 through the setting of the support frame 5. The setting of the third sensor 29 can determine the angle of rotation of the swing frame 27, which is convenient for adjusting the position of the workpiece, thereby facilitating the assembly operation of the workpiece. While performing the assembly operation, the vibration motor 11 can be turned on to make the workpiece vibrate, thereby reducing the microscopic fitting deviation between the workpieces through vibration, thereby reducing stress concentration and improving the quality of assembly.

[0080] If it is necessary to assemble different positions of the clamped workpiece, it is also necessary to adjust the circumferential position of the workpiece. At this time, the first driving motor 9 is turned on, and the first driving motor 9 drives the worm 8 to rotate, and the worm 8 can drive the worm wheel 7 to rotate, thereby driving the rotating cylinder 6 to rotate. At this time, the vibration motor 11 is in the off state. As the rotating cylinder 6 rotates, the buffer mounting cylinder 13 is driven to rotate, and the buffer mounting cylinder 13 can be synchronously driven to rotate through the setting of the groove 14, so that the protrusion 15 on the top of the buffer mounting cylinder 13 and the groove 14 at the bottom of the connecting cylinder 10 are adapted. The connecting cylinder 10 is matched, thereby driving the connecting cylinder 10 to rotate. When vibration occurs, the vibration can be eliminated by the setting of the buffer mounting cylinder 13, thereby improving the anti-vibration effect of the entire mechanism, thereby reducing the impact of vibration on the entire mechanism. The cooperation of the groove 14 and the protrusion 15 facilitates more accurate adjustment of the rotation of the assembly platform 3. The setting of the annular groove 16 and the mounting ring 17 improves the tightness of the installation between the buffer mounting cylinder 13 and the rotating cylinder 6 and the connecting cylinder 10, and improves the stability during operation. After completing the assembly, retract the second driving member 30 and remove the workpiece.

[0081] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
