Abstract
Description
Technical Field
[0001] This invention relates to the field of bolt disassembly and assembly technology, and in particular to a disassembly and assembly mechanism. Background Technology
[0002] In industries such as pipe pile products, automobiles, wind power, and military, there is a need for tightening or loosening screws. To automate screw tightening, for screws with good spacing control, regularity, and favorable operating environments, automatic tightening or loosening can be largely achieved with the assistance of vision guidance. However, for screws with poor spacing control, poor regularity, or poor operating environments—such as when the optical lens of the vision guide is easily soiled, or when there are obstructions or significant vibrations in the visual inspection angle—it is difficult to precisely align the tool with the screw, making automation difficult and requiring manual operation of the tool for tightening or loosening, resulting in high labor intensity. Summary of the Invention
[0003] The purpose of this invention is to provide a disassembly and assembly mechanism that can be applied to automatically tighten or disassemble screws with poor spacing control, poor regularity, or poor operating environment.
[0004] A disassembly / assembly mechanism, comprising:
[0005] Driver components;
[0006] A connecting seat is connected to the drive assembly to reciprocate along a first direction and a second direction perpendicular to the first direction under the action of the drive assembly;
[0007] A mounting base is connected to the connecting base, and the mounting base can be adjusted in a third and a fourth direction relative to the connecting base under the action of an external force;
[0008] The drive unit is disassembled and assembled, and is located on the mounting base; and
[0009] A disassembly sleeve is connected to the disassembly drive component to rotate about an axis parallel to the second direction under the action of the disassembly drive component. The disassembly sleeve has a guide channel and a docking channel connected in sequence. The guide channel has an open end penetrating the disassembly sleeve and a connecting end communicating with the docking channel. The radial dimension of the guide channel gradually decreases from the open end to the connecting end, and the radial dimension of the connecting end is greater than or equal to the radial dimension of the docking channel.
[0010] Both the third direction and the fourth direction are perpendicular to the second direction.
[0011] By setting up the above-mentioned disassembly and assembly mechanism, the connecting seat first moves above the screw under the action of the drive component, and then the connecting seat moves along the second direction to approach the screw under the action of the drive component until the screw passes through the guide channel and enters the docking channel to dock with the disassembly and assembly sleeve. Next, the disassembly and assembly drive component drives the disassembly and assembly sleeve to rotate, thereby realizing the tightening or disassembly of the screw.
[0012] Because the mounting base can be adjusted relative to the connecting base under external force, and the radial dimension of the guide channel opening is large, when tightening and disassembling screws with poor spacing control, poor regularity, or poor operating environment, even if the disassembly sleeve and the screw cannot be precisely aligned, the screw can still enter the guide channel. As the screw enters the mating channel along the guide channel, the screw will provide a force to adjust the position of the mounting base, so that the mating channel can mate with the screw, realizing automated processing of screw tightening and disassembly without manual operation, thus improving disassembly and assembly efficiency.
[0013] In one embodiment, the disassembly and assembly mechanism further includes multiple sets of connecting components, each of which is connected between the mounting base and the connecting base, so that the mounting base can be adjusted relative to the connecting base in the third and fourth directions under the action of external forces.
[0014] In one embodiment, each of the connecting components includes two connecting shafts, two universal bearings, and a connecting rod. The two connecting shafts are fixedly connected to the connecting seat and the mounting seat, respectively. The two universal bearings are connected to the two connecting shafts, respectively. The connecting rod is connected between the two universal bearings.
[0015] In one embodiment, the mounting base has an initial position relative to the connecting base during the adjustment of its position in the third and fourth directions. The disassembly and assembly mechanism further includes a positioning component connected to the connecting base and capable of abutting against the mounting base, for providing a force to reset the mounting base to the initial position or to maintain it in the initial position.
[0016] When the mounting base is in the initial position, the mounting base and the connecting base are arranged at intervals along the second direction.
[0017] In one embodiment, the positioning component includes a plurality of first elastic members and a plurality of abutting members, each of the first elastic members being connected between the connecting seat and a corresponding abutting member, such that the abutting member abuts against the side of the mounting seat facing the connecting seat.
[0018] In one embodiment, the mounting base has a plurality of tapered grooves on the side facing the connecting base, and each abutment can extend into a corresponding tapered groove to abut against the mounting base.
[0019] In one embodiment, the positioning assembly further includes a positioning seat and multiple guide rods. The positioning seat is fixedly connected to the side of the connecting seat facing the mounting seat. Each guide rod is fixedly connected to the side of the positioning seat facing the mounting seat. Each first elastic member is sleeved on a corresponding guide rod and connected between the positioning seat and a corresponding abutment member.
[0020] In one embodiment, the disassembly and assembly mechanism further includes a torque limiter and a detector. The torque limiter is connected between the disassembly and assembly drive and the disassembly and assembly sleeve. The detector is disposed on the mounting base and is electrically connected to the disassembly and assembly drive. The torque limiter can trigger the detector when the torque of the disassembly and assembly sleeve reaches a preset torque, so as to stop the disassembly and assembly drive.
[0021] In one embodiment, the disassembly and assembly mechanism further includes a drive shaft, a floating structure, and a second elastic element. The disassembly and assembly drive element is drivenly connected to the drive shaft. The drive shaft is connected to the disassembly and assembly sleeve through the floating structure, so that the disassembly and assembly sleeve can reciprocate relative to the drive shaft in the second direction and swing relative to the drive shaft. The disassembly and assembly sleeve has a central position during the reciprocating movement in the second direction and the swinging relative to the drive shaft. The second elastic element is connected between the drive shaft and the disassembly and assembly sleeve to provide a force to reset the disassembly and assembly sleeve to the central position or maintain it in the central position.
[0022] When the disassembly sleeve is in the central position, the disassembly sleeve extends longitudinally along the second direction, and the disassembly sleeve can tilt relative to the second direction during the swinging process relative to the drive shaft.
[0023] In one embodiment, the disassembly and assembly mechanism further includes a vision detector for detecting the position of the workpiece to be disassembled or assembled, and the vision detector is electrically connected to the drive assembly. Attached Figure Description

[0035] like Figures 1 to 3 As shown, an embodiment of the present invention provides a disassembly and assembly mechanism 100 for tightening or loosening screws. The disassembly and assembly mechanism 100 includes a drive assembly 10, a connecting seat 21, a mounting seat 22, a disassembly and assembly drive component 23, and a disassembly and assembly sleeve 24.
[0036] The drive assembly 10 is drively connected to the connecting seat 21 to drive the connecting seat 21 to reciprocate along a first direction and a second direction perpendicular to the first direction. The mounting seat 22 is connected to the connecting seat 21, and the mounting seat 22 can be adjusted relative to the connecting seat 21 in a third and fourth direction under the action of external force. The disassembly and assembly drive component 23 is disposed on the mounting seat 22 and connected to the disassembly and assembly sleeve 24 to drive the disassembly and assembly sleeve 24 to rotate about an axis parallel to the second direction.
[0037] The disassembly sleeve 24 has a guide channel and a docking channel connected in sequence. The guide channel has an open end that passes through the disassembly sleeve 24 and a connecting end that communicates with the docking channel. The radial dimension of the guide channel gradually decreases from the open end to the connecting end, and the radial dimension of the connecting end is greater than or equal to the radial dimension of the docking channel.
[0038] It should be explained that, in this embodiment, the first direction is... Figure 1 The direction perpendicular to the paper, the second direction is Figure 1 The first direction is vertical, while the second direction is perpendicular to the third direction and the fourth direction is the same as the first direction. In other embodiments, the third direction and the fourth direction can be two different directions that are perpendicular to the second direction.
[0039] Furthermore, the mounting base 22 can move relative to the connecting base 21 in the third and fourth directions to adjust its position. The third and fourth directions are different and both are perpendicular to the second direction. From the composition and decomposition of the motion, it can be concluded that the mounting base 22 can adjust its position relative to the connecting base 21 in any direction perpendicular to the second direction.
[0040] By setting up the above-mentioned disassembly and assembly mechanism, the connecting seat 21 first moves to above the screw under the action of the drive component 10, and then the connecting seat 21 moves along the second direction to approach the screw under the action of the drive component 10 until the screw passes through the guide channel and enters the docking channel to dock with the disassembly and assembly sleeve 24. Next, the disassembly and assembly drive component 23 drives the disassembly and assembly sleeve 24 to rotate, so as to lock or disassemble the screw.
[0041] Because the mounting base 22 can be adjusted relative to the connecting base 21 under the action of external force, and the radial dimension of the guide channel opening is large, when tightening and disassembling screws with poor spacing control, poor regularity, or poor operating environment, even if the disassembly sleeve 24 and the screw cannot be precisely aligned, the screw can still enter the guide channel. During the process of the screw entering the docking channel along the guide channel, the screw will provide a force to the mounting base 22 to adjust its position, so that the docking channel can dock with the screw, realizing the automated processing of screw tightening and disassembly without manual operation, thus improving disassembly and assembly efficiency.
[0042] It needs to be explained that, Figure 1 The opening end of the guide channel in the disassembly sleeve 24 is the bottom end of the disassembly sleeve 24. The radial dimension of the guide channel gradually decreases from the opening end to the connection end. The guide channel can be a slope or a stepped structure, but the span of the step cannot be too large, so as to ensure that after the screw enters the guide channel from the opening end of the guide channel, it can move along the guide channel and enter the mating channel.
[0043] It is understandable that there is a deviation between the disassembly sleeve 24 and the screw, but the deviation will not be particularly large. That is, after the drive assembly 10 drives the connecting seat 21 to move above the screw in the first direction, the mating channel in the disassembly sleeve 24 is not coaxial with the screw in the second direction. However, during the process of the disassembly sleeve 24 moving towards the screw, the screw can enter the guide channel from the opening end of the guide channel.
[0044] It should be noted that if the mating channel and the screw are not aligned, after the screw enters the guide channel, the screw will abut against the side wall of the guide channel. As the disassembly sleeve 24 moves, the screw will provide the disassembly sleeve 24 with a force in the third and fourth directions through the guide channel, so that the mounting base 22 automatically adjusts its position until the screw enters the mating channel.
[0045] In some embodiments, the drive assembly 10 includes a first drive member 11 and a second drive member 12. The first drive member 11 is driven to the second drive member 12 to drive the second drive member 12 to reciprocate along a first direction. The second drive member 12 is driven to the connecting seat 21 to drive the connecting seat 21 to reciprocate along a second direction.
[0046] Furthermore, the drive assembly 10 also includes a slide 13, a first drive member 11 is connected to the slide 13 to drive the slide 13 to reciprocate along a first direction, a second drive member 12 and a connecting seat 21 are both disposed on the slide 13, and the connecting seat 21 can reciprocate along a second direction.
[0047] In practical applications, the first driving component 11 is a motor, which can be connected to the second driving component 12 through a gear module or a lead screw module. The second driving component 12 is a cylinder or a motor that works with a gear rack, lead screw module, chain, etc.
[0048] In some embodiments, the disassembly and assembly mechanism further includes multiple sets of connecting components 30, each connecting component 30 being connected between the mounting base 22 and the connecting base 21, so that the mounting base 22 can be adjusted relative to the connecting base 21 in a third and a fourth direction under the action of external force.
[0049] Furthermore, each connecting assembly 30 includes two connecting shafts 31, two universal bearings 32, and a connecting rod 33. The two connecting shafts 31 are fixedly connected to the connecting seat 21 and the mounting seat 22, respectively. The two universal bearings 32 are connected to the two connecting shafts 31, respectively. The connecting rod 33 is connected between the two universal bearings 32.
[0050] Combination Figure 3As can be seen, taking any two sets of connecting components 30 as an example, since the two ends of the connecting rod 33 are respectively connected to two universal bearings 32, an unstable quadrilateral is formed between the two sets of connecting components 30. When the mounting base 22 is subjected to a horizontal force, the mounting base 22 will adjust its position in the horizontal direction, that is, adjust its position in the third and fourth directions as mentioned above.
[0051] Furthermore, it should be explained that since the length of the connecting rod 33 is fixed, it will tilt during the adjustment of the mounting base 22 in the third and fourth directions, thus reducing the distance between the mounting base 22 and the connecting base 21. Therefore, during the adjustment of the mounting base 22 in the third and fourth directions, the mounting base 22 will also adjust its position in the second direction.
[0052] Of course, in other embodiments, the mounting base 22 can also be directly and reciprocally connected to the connecting base 21 along the third and fourth directions. In this case, the mounting base 22 can still be adjusted in the third and fourth directions under the action of external force, but the mounting base 22 will not be displaced in the second direction during the adjustment process.
[0053] In order to enable the mounting base 22 to be reciprocally connected to the connecting base 21 in the third and fourth directions, a sliding plate can be added between the mounting base 22 and the connecting base 21. The sliding plate is reciprocally connected to the connecting base 21 in the third direction, and the mounting base 22 is reciprocally connected to the sliding plate in the fourth direction.
[0054] In practical applications, the disassembly and assembly mechanism includes four sets of connecting components 30. The connecting shaft 31 is connected to the side of the connecting seat 21 or the mounting seat 22. During the process of adjusting the position of the mounting seat 22 relative to the connecting seat 21 in the third and fourth directions, the bottom surface of the mounting seat 22 and the top surface of the connecting seat 21 are always parallel.
[0055] Of course, in other embodiments, only two or three sets of connecting components 30 may be provided. This is not a limitation, as long as the mounting base 22 can be adjusted relative to the connecting base 21.
[0056] In some embodiments, the mounting base 22 has an initial position during the adjustment of its position relative to the connecting base 21 in the third and fourth directions.
[0057] The disassembly and assembly mechanism also includes a positioning component 40, which is connected to the connecting seat 21 and can abut against the mounting seat 22 to provide a force to reset the mounting seat 22 to its initial position or to keep it in its initial position.
[0058] When the mounting base 22 is in its initial position, the mounting base 22 and the connecting base 21 are arranged at intervals along the second direction, i.e. Figure 1As shown, the connector 21 is located directly above the mounting base 22.
[0059] In some embodiments, the positioning component 40 includes a plurality of first elastic elements 41 and a plurality of abutting elements 42, each of the first elastic elements 41 being connected between the connecting seat 21 and a corresponding abutting element 42, such that the abutting element 42 presses against the side of the mounting seat 22 facing the connecting seat 21.
[0060] Combination Figure 1 Understandably, when multiple abutting members 42 press against the side of the mounting base 22 facing the connecting base 21 via multiple first elastic members 41, and the mounting base 22 is in its initial position, the multiple abutting members 42 will exert multiple pressures of the same magnitude and direction on the mounting base 22, with the pressure direction being downward. These multiple vertically downward pressures of the same magnitude can keep the mounting base 22 horizontal. Moreover, when the mounting base 22 is moved away from its initial position by an external force, and after the external force disappears, the pressure provided by the multiple abutting members 42 will also cause the mounting base 22 to tend to return to a horizontal position, thus resetting the mounting base 22 to its initial position.
[0061] Furthermore, when the mounting base 22 is in the initial position, the first elastic element 41 is vertical. After the mounting base 22 leaves the initial position, the first elastic element 41 will tilt relative to the vertical direction. The tilted first elastic element 41 has a tendency to return to the vertical direction, thereby providing a force that allows the mounting base 22 to return to the horizontal position, so that the mounting base 22 remains in the initial position when it is not subjected to external force.
[0062] Furthermore, the positioning assembly 40 also includes a positioning seat 43 and multiple guide rods (not shown in the figure). The positioning seat 43 is fixedly connected to the side of the connecting seat 21 facing the mounting seat 22. Each guide rod is fixedly connected to the side of the positioning seat 43 facing the mounting seat 22. Each first elastic member 41 is sleeved on a corresponding guide rod and connected between the positioning seat 43 and a corresponding abutment member 42.
[0063] In practical applications, the positioning component 40 includes four guide rods, four first elastic elements 41 and four abutment elements 42, wherein the first elastic elements 41 are springs and the abutment elements 42 are balls.
[0064] In some embodiments, the mounting base 22 has a plurality of tapered grooves on the side facing the connecting base 21. Each abutment 42 can extend into a corresponding tapered groove to abut against the mounting base 22, so that the mounting base 22 is reset to the initial position or kept in the initial position under the action of the abutment 42. At the same time, the tapered groove can also prevent the abutment 42 from disengaging from the mounting base 22.
[0065] In some embodiments, the disassembly and assembly mechanism further includes a torque limiter 25 and a detector 26. The torque limiter 25 is connected between the disassembly and assembly drive 23 and the disassembly and assembly sleeve 24. The detector 26 is disposed on the mounting base 22 and is electrically connected to the disassembly and assembly drive 23. The torque limiter 25 can trigger the detector 26 when the torque of the disassembly and assembly sleeve 24 reaches a preset torque, so as to stop the disassembly and assembly drive 23 and avoid excessive torque from damaging the screw or the disassembly and assembly sleeve 24.
[0066] It should be explained that the torque limiter 25 is an existing device, while the detector 26 is a photoelectric sensor. The torque controller is equipped with a spring and a roller. As the torque increases, the spring is compressed. When the torque reaches the preset torque, the compression of the spring exceeds the diameter of the roller, and the roller will jump out of the roller groove. At this time, the photoelectric sensor can be triggered. After being triggered for 0.2 seconds, the sensor will send a stop signal to the disassembly and assembly drive 23, causing the disassembly and assembly drive 23 to stop.
[0067] In some embodiments, the disassembly drive 23 is a tightening gun, a pneumatic wrench, or other drive mechanism capable of providing torque.
[0068] In some embodiments, the disassembly and assembly mechanism further includes a drive shaft 27, a floating structure, and a second elastic element 28. The disassembly and assembly drive member 23 is connected to the drive shaft 27. The drive shaft 27 is connected to the disassembly and assembly sleeve 24 through the floating structure, so that the disassembly and assembly sleeve 24 can reciprocate relative to the drive shaft 27 in a second direction and swing relative to the drive shaft 27. The disassembly and assembly sleeve 24 has a central position during the reciprocating movement in the second direction and the swinging relative to the drive shaft 27. The second elastic element 28 is connected between the drive shaft 27 and the disassembly and assembly sleeve 24 to provide a force to reset the disassembly and assembly sleeve 24 to the central position or to keep it in the central position.
[0069] When the disassembly sleeve 24 is in the centered position, the disassembly sleeve 24 extends longitudinally along the second direction, and the disassembly sleeve 24 can tilt relative to the second direction during the swinging process relative to the drive shaft 27.
[0070] With the screw in a vertical position, the disassembly sleeve 24 can be moved directly toward the screw in the second direction, i.e., the vertical direction, so that the screw aligns with the mating channel in the disassembly sleeve 24. When the screw has a certain tilt angle, the screw first enters the guide channel of the disassembly sleeve 24. Then, under the action of the screw, the disassembly sleeve 24 will swing relative to the drive shaft 27, thereby tilting relative to the vertical direction to accommodate the tilted screw, so that the screw can enter the mating channel and align with the mating channel.
[0071] It should be noted that the floating structure is similar to a universal coupling, but the floating structure can also float up and down. That is, one end of the universal coupling can be reciprocated along the second direction and connected to the drive shaft 27, while the detachable sleeve 24 is connected to the other end of the universal coupling. No restrictions are imposed here.
[0072] The second elastic element 28 is also a spring. The spring is at least partially sleeved on the drive shaft 27, and one end of the spring abuts against the disassembly sleeve 24. Similarly, the spring abuts against the top surface of the disassembly sleeve 24. The spring can provide a vertically downward force on countless points on the top surface of the disassembly sleeve 24, thereby making the disassembly sleeve 24 tend to return to the center position or remain in the center position.
[0073] Furthermore, it should be noted that the second elastic element 28 can be a spring with a larger diameter, so that after the disassembly sleeve 24 deviates from the center position, it can quickly return to the center position.
[0074] In practical applications, the torque controller is connected between the disassembly / assembly drive unit 23 and the drive shaft 27.
[0075] In some embodiments, the disassembly and assembly mechanism further includes a vision detector 26, which is used to detect the position of the screw and is electrically connected to the drive assembly 10 so that the drive assembly 10 drives the connecting seat 21 to move according to the detection result of the vision detector 26, ensuring that the disassembly and assembly sleeve 24 can mate with the screw.
[0076] It is understood that in other embodiments, the screw can also be other workpieces to be disassembled, as long as the disassembly sleeve 24 can mate with the corresponding workpiece to be disassembled.
[0077] Furthermore, it should be noted that when the visual detector 26 is contaminated, the disassembly and assembly mechanism in the above embodiment can still achieve the docking of the disassembly and assembly sleeve 24 and the screw even when there is a certain deviation between the disassembly and assembly sleeve 24 and the screw.
[0078] To facilitate understanding of the technical solution of this invention, it is combined with... Figure 1 The workflow of the disassembly and assembly mechanism in the above embodiments is described as follows:
[0079] The first driving component 11 drives the second driving component 12 to move along the first direction until the connecting seat 21 is above the screw. Then, the second driving component 12 drives the connecting seat 21 to move downward until the disassembly sleeve 24 is engaged with the screw. Next, the disassembly driving component 23 operates to drive the disassembly sleeve 24 to rotate, thereby tightening or removing the screw.
[0080] It should be noted that when the disassembly sleeve 24 and the screw do not correspond in the second direction, that is, there is a deviation between the disassembly sleeve 24 and the screw, and the screw can still enter the guide channel of the disassembly sleeve 24, the second driving component 12 drives the connecting seat 21 to move downward. The screw first enters the guide channel, and then under the action of the screw, the mounting seat 22 will adjust its position relative to the connecting seat 21 until the screw enters the docking channel. At this time, the disassembly sleeve 24 and the screw are docked.
[0081] When the screw is tilted to a certain extent relative to the second direction and can enter the guide channel of the disassembly sleeve 24, the second driving member 12 drives the connecting seat 21 to move toward the screw until the screw enters the guide channel. Under the action of the screw, the disassembly sleeve 24 tilts to correspond with the screw, so that the screw enters the docking channel to complete the docking of the disassembly sleeve 24 and the screw.
[0082] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0083] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
