Self-adaptive bolt disassembling device

Abstract

The invention relates to a self-adaptive bolt disassembling device. The device comprises a bottom plate, six drawing modules, six baffles and a driving module, the six driving modules are connected to the bottom plate and are uniformly distributed in a circumferential array; the six baffles are encircled to form a regular hexagonal disassembling area; and the drawing module is used for driving all the baffles to synchronously get close to or get away from the center direction of the disassembling area under the condition that the angles are not changed, so that the side length of the disassembling area is changed. The drawing modules are orderly and uniformly distributed on the bottom plate, so that when the drawing plate moves, the baffles can be synchronously close to or far away from the center direction of the disassembling area under the condition that the angle is not changed, and thus hexagons with different side lengths can be defined. The size of the disassembling area composed of the hexagons can be changed so as to adapt to bolt heads of different specifications, and therefore when bolts of different specifications are used, bolt disassembling heads of different specifications do not need to be replaced.

Description

Technical Field

[0001] The invention relates to the technical field of automated disassembly, and in particular to an adaptive bolt disassembly device. Background Art

[0002] With the continuous development of artificial intelligence, automation has gradually been integrated into people's lives, and automation plays a vital role in the industrial field. First of all, in the field of automated disassembly, people have proposed many disassembly line devices for bolt disassembly, but they only focus on discussing the composition of the disassembly line, and do not focus on discussing the disassembly device and how to achieve intelligent disassembly of bolts. In the current field of bolt disassembly, most of them require manual or artificial intelligence to identify the specifications of the bolts, and further select the bolt disassembly head suitable for its specifications, which leads to two problems: 1. Various types of bolt disassembly heads need to be prepared, which causes a waste of resources. 2. When disassembling different types of bolts, the disassembly head needs to be replaced with an appropriate model, which greatly increases the time cost of disassembly, thereby reducing the disassembly income.

[0010] One end of the two elastic paddles is connected to the pull-out plate, and the other end corresponds to the two locking cranks one by one; the elastic paddles are used to prevent the connecting pin from being attracted by the magnet when the connecting pin moves from the strip groove one to the strip groove two.

[0011] As a preferred example, a sliding groove is provided on the side edge of the baffle, and a slider is slidably connected to the inner wall of the sliding groove; the side of the baffle provided with the sliding groove is rotatably connected to a connecting pin in one of the pull-out modules; and the slider is rotatably connected to a connecting pin in another pull-out module.

When the pull-out plate moves, the baffle can be synchronously moved closer to or away from the center of the disassembling area without changing the angle, so as to enclose and form a hexagon with different side lengths. The disassembling area composed of the hexagon can change its size to adapt to bolt heads of different specifications. Therefore, when facing bolts of different specifications, there is no need to replace bolt disassembling heads of different specifications, which reduces resource waste and greatly improves disassembly efficiency.

[0027] 2. Compared with the traditional bolt disassembling device, the disassembling area surrounded by six baffles in the present invention can completely cover the plug head. Since the contact area between the baffles and the side of the bolt head is large, the force will be more uniform during disassembly, which reduces the problem of damage to the bolt due to excessive stress during the disassembly process.

The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0046] Please refer to Figure 1 and Figure 2, this embodiment provides an adaptive bolt disassembly device, which includes a shell 16, a base plate 1, six pull-out modules, six baffles 2 and a drive module. The shell 16 can be set to a cylindrical shape, one end of which is set to an opening, and the base plate 1 is fixedly connected to the inner wall near the opening of the shell 16. A disassembly port is opened at the other end of the shell 16. The base plate 1 is used to carry and install related parts, and it can be designed to be lightweight, and the material consumption and the weight of the base plate 1 can be reduced by hollowing out, opening holes, etc. The six pull-out modules are all installed on the same side of the base plate 1, and are evenly distributed in a circular array along the center of the base plate 1. Six baffles 2 are installed on the six pull-out modules, and the six baffles 2 are surrounded to form a disassembly area in the shape of a regular hexagon. The disassembly area is the working area for screwing the bolts, and the disassembly area corresponds to the disassembly port on the shell 16. In addition, a removable dust cover 17 can be provided at the disassembly port. When the disassembly area is not in operation, the dust cover 17 is closed to reduce the pollution of dust, oil and the like to the internal parts of the housing 16. The function of the pull-out module is to drive all baffles 2 to move toward or away from the center of the disassembly area synchronously without changing the angle, thereby changing the side length of the disassembly area. The specifications of the disassembly area are changed to adapt to bolt heads of different specifications. The drive module is used to drive the pull-out module to move to change the specifications of the disassembly area. The adaptive bolt disassembly device can be used instead of the traditional bolt disassembly head and installed on the corresponding automated disassembly line.

[0047] Specifically, each drawer module structure in this embodiment is consistent. Figure 3 , Figure 4 and Figure 5 , which include a pull-out shell 3, a pull-out plate 4, a spring 5, two locking cranks 6, two connecting pins 7, two elastic paddles 8 and a plurality of magnets. Among them, the pull-out shell 3 can be set to a box shape, and the length direction of the box body needs to be set to the direction toward the center of the disassembly area. The pull-out shell 3 is fixedly connected to the bottom plate 1. Two adjustment grooves symmetrically distributed along the center line of the width direction of the pull-out shell 3 are provided on one side of the pull-out shell 3. The design of the adjustment groove is a focus of the present invention. Each adjustment groove includes a connected strip groove 1 31, a strip groove 2 32 and a gear groove. Take one of the adjustment grooves as an example for explanation. As Figure 6As shown, the strip groove 2 32, the shift groove and the strip groove 1 31 are sequentially distributed along the length direction of the draw-out shell 3, and the strip groove 1 31, the strip groove 2 32 and the shift groove are sequentially distributed in the width direction of the draw-out shell 3. The shift groove is further divided into a plurality of slots 33 in the length direction of the draw-out shell 3. The above features constitute an adjustment slot with special functions. The number of slots 33 determines the range of adjustable bolt disassembly specifications. In this embodiment, the number of slots 33 is set to four. Magnets are connected in each slot 33. The function of the magnet is to attract the magnetic connecting pin 7 into the slot 33. The other side of the draw-out shell 3 relative to the adjustment slot can be designed to be lightweight, removing the entire surface and only retaining the protrusion to cooperate with the draw-out plate 4 so that it can be slidably connected. The sliding direction of the draw-out plate 4 is the length direction of the draw-out shell 3. The two ends of the spring 5 are fixedly connected to the draw-out shell 3 and the draw-out plate 4 respectively. The function of the spring 5 is to reset the draw-out plate 4 to the initial position, that is, the position of the draw-out plate 4 when the disassembly area is the smallest. One end of the two locking cranks 6 is hinged to the pull-out plate 4. The other ends of the two locking cranks 6 are connected to the connecting pin 7. The two connecting pins 7 extend into different adjustment slots, respectively, and the ends of the two connecting pins 7 away from the locking cranks 6 are connected to different baffles 2. One end of the two elastic paddles 8 is fixedly connected to the pull-out plate 4, and the other end corresponds to the two locking cranks 6 one by one. The function of the elastic paddles 8 is to prevent the connecting pin 7 from being attracted by the magnet during the process of the connecting pin 7 moving from the strip groove 1 31 to the strip groove 2 32. Please refer to Figure 7 , Figure 8 , Fig. 9 and Fig.10(The drawer plate 4 is not shown in the figure), the following will introduce how the drawer module in this embodiment works: Assuming that the drawer plate 4 is in the initial position, the connecting pin 7 is located in the second strip groove 32, and the rotation angle of the locking crank 6 is also the initial value. The moving direction of the connecting pin 7 is the second strip groove 32--the gear groove--the first strip groove 31--the second strip groove 32. When the connecting pin 7 is located in the second strip groove 32, the elastic paddle 8 does not cooperate with the groove on the locking crank 6, and the two are independent of each other. When the drawer plate 4 is pulled, the connecting pin 7 starts to move in the locking groove 33 in turn. When the connecting pin 7 passes through the corresponding locking groove 33, it will be attracted by the magnet in the locking groove 33 and enter the inside of the locking groove 33. At this time, if the drawer plate 4 is stopped, the connecting pin 7 will be fixed at the corresponding locking groove 33. When the drawer plate 4 continues to be pulled, the connecting pin 7 overcomes the attraction of the magnet and moves along the inclined surface in the locking groove 33. It is worth mentioning that when the connecting pin 7 moves between the slots 33, the connecting pin 7 will not completely enter the strip groove 1 31, that is, the angle of rotation of the locking crank 6 driven by the connecting pin 7 is small, so that the elastic pick 8 will not cooperate with the locking crank 6. When the connecting pin 7 passes through multiple slots 33 in sequence and finally enters the strip groove 1 31, the locking crank 6 generates a large rotation angle driven by the connecting pin 7, so that the elastic pick 8 is just stuck in the groove on the locking crank 6, and the two form a whole and move together. When the connecting pin 7 is in the strip groove 1 31, the pull-out plate 4 is released. The pull-out plate 4 will return to the original position under the action of the spring 5 (the transition surface between the strip groove 1 31 and the strip groove 2 32 is an inclined surface. The connecting pin 7 enters the strip groove 2 32 from the strip groove 1 31 under the action of the inclined surface), that is, the connecting pin 7 returns to the strip groove 2 32. In the process of the connecting pin 7 returning to the strip groove 2 32, the elastic paddle 8 is always connected to the locking crank 6, and its function is to prevent the connecting pin 7 from being attracted by the magnet and re-entering the locking groove 33 in the process of the connecting pin 7 moving from the strip groove 1 31 to the strip groove 2 32. When the connecting pin 7 moves from the strip groove 1 31 to the strip groove 2 32, the locking crank 6 rotates, and the change in its angle causes the elastic paddle 8 to separate from the locking crank 6 and become independent individuals again. The above process is repeated cyclically so that the connecting pin 7 is located in different locking grooves 33, thereby adjusting the size of the disassembly area. It should be noted that the shape design of the locking groove 33 needs to ensure that the connecting pin 7 will not fall out of the locking groove 33 during operation, that is, the baffle 2 can remain fixed when the bolts are disassembled. The force of pulling the pull plate 4 can push the connecting pin 7 out of the locking groove 33, that is, the baffle 2 can move when adjusting the gear position. Please refer to again Figure 6, W represents the rotation direction of the drawer shell 3. F1 represents the pulling force provided by the spring 5, and F2 represents the attraction of the magnet to the connecting pin 7. F4 represents the force exerted by the drawer shell 3 on the connecting pin 7 during operation. F3 represents the combined force of the forces exerted by F1 and F2 on the connecting pin 7 when the shell is in a stationary state. It can be seen from this that in the motion state, as long as the vector sum of F1, F2, -F3 (the force exerted by the drawer shell 3 on the connecting pin 7, which is equal to F3 in magnitude and opposite in direction) and F4 is kept at 0, the connecting pin 7 can be kept in a balanced state, so that it will not fall out of the slot 33 during operation. Following this principle, the specific shape of the slot 33 can be obtained through a limited number of experiments, and will not be elaborated on here.

[0048] like Fig.11 As shown, the baffle 2 in this embodiment can be set to a rectangular shape. The baffle 2 is arranged vertically relative to the bottom plate 1. The edge of one baffle 2 faces the side of another baffle 2. The six baffles 2 are arranged in sequence, so that a regular hexagonal disassembly area is enclosed in the middle position of the six baffles 2. In the specific connection structure of the baffle 2 and the pull-out module, a slide groove is provided on the side edge of the baffle 2. A slider is slidably connected to the inner wall of the slide groove. The slider is rotatably connected to the connecting pin 7 in one of the pull-out modules. The side of the baffle 2 with the slide groove is also connected to a connecting seat. The connecting seat is rotatably connected to the connecting pin 7 in another pull-out module. Further, in order to facilitate the description, the adjustment groove of the same pull-out shell 3 is divided into a left adjustment groove and a right adjustment groove. The same baffle 2 is rotatably connected to the connecting pin 7 in the left adjustment groove on one of the pull-out shells 3, and the baffle 2 needs to be rotatably connected to the connecting pin 7 in the right adjustment groove of another pull-out shell 3 at the same time, and the two pull-out shells 3 connected by the same baffle 2 are arranged adjacently. In general, one baffle 2 cooperates with the connecting pins 7 in two pull-out modules at the same time. When the pull-out plate 4 is pulled, the position of the baffle 2 will also change accordingly. Since the pull-out modules are evenly distributed in a circular array on the bottom plate 1 (i.e., the angle between the center lines of adjacent pull-out shells 3 is 60°), the positions of the baffles 2 are always parallel to each other. Different card slots 33 correspond to different positions of the baffle 2, thus forming disassembly areas of different sizes and specifications, which can disassemble bolts of different models and specifications, and the disassembly area surrounded by six baffles 2 can completely cover the plug head. Since the baffle 2 has a large contact area with the side of the bolt head, the force will be more uniform during disassembly, which reduces the problem of damage to the bolts due to excessive stress during the disassembly process.

[0049] The driving module is used to drive the pull-out module to move so as to change the size of the disassembly area. Fig.12The drive module includes a bracket 9, a connecting plate 10, a drive ring 11, six positioning blocks 12 and six wiring harnesses 13. The bracket 9 can be designed to be lightweight and has a circular shape. A positioning hole is provided at the center of the bracket 9, and a positioning pin 15 is fixedly connected to the center of the bottom plate 1. Fig.13 As shown. A positioning seat is fixedly connected at the center of the connecting plate 10. The positioning pin 15 passes through the positioning hole and is assembled with the positioning seat, so that the bracket 9 is rotatably set between the base plate 1 and the connecting plate 10. The connecting plate 10 can be set as a circle as a whole, and its position relative to the bracket 9 is fixed. Six arc grooves are provided at the edge of the connecting plate 10. The center of the circle of the six arc grooves is the center of the disassembly area, and the six arc grooves are evenly distributed on the connecting plate 10 in a ring shape with the center of the circle of the connecting plate 10, corresponding to the six baffles 2 one by one. At the same time, a winding post 14 and a limit block are also fixedly connected on one side of each arc groove on the connecting plate 10. The winding post 14 is used to wind the wiring harness 13, so that the direction of the force of the wiring harness 13 on the pull-out plate 4 is consistent with the movement direction of the pull-out plate 4. A limit groove is provided on the limit block. The installed wiring harness 13 passes through the limit groove, which ensures the stability of the pull-out plate 4 in the movement direction and enables the wiring harness 13 to accurately bypass the winding post 14. The driving ring 11 is rotatably connected to the side of the connecting plate 10 away from the bracket 9. The positioning block 12 runs through the arc block setting and is slidably connected to the inner wall of the arc groove. The six positioning blocks 12 correspond to the six arc grooves one by one, and the positioning blocks 12 run through the arc groove, and the positioning blocks 12 are slidably connected to the inner wall of the arc groove. At the same time, one end of each positioning block 12 is connected to the bracket 9, and the other end is connected to the driving ring 11. One end of each wiring harness 13 is respectively connected to one of the positioning blocks 12, and after bypassing the winding column 14, the other end of the wiring harness 13 is respectively connected to one of the pull-out plates 4. In this way, when the external force drives the driving ring 11 to rotate, the driving ring 11 drives the positioning block 12 to move, and the movement of the positioning block 12 will drive the pull-out plate 4 to move through the wiring harness 13, thereby driving the above-mentioned pull-out module to work and changing the position of the baffle 2. In order to fix the position of the positioning block 12, a plurality of fixing holes connected to the arc groove are provided on the outer edge of the connecting plate 10 in this embodiment. A fixing hole 2 corresponding to the fixing hole 1 is provided on the positioning block 12. When the positioning block 12 moves to a certain position, the positioning block 12 is locked by setting fixing pins in the fixing hole 1 and the fixing hole 2 to fix the currently selected gear. Of course, the structure of the drive module is not limited to this. The design of the above-mentioned drive module can be subsequently adapted according to the working conditions and the shape of the drive ring 11 can be optimized without affecting the disassembly device. In another embodiment, the structure of the drive module can be further simplified. The drive module can directly use parts such as the wiring harness 13 and the winding pole 14, so that one end of the wiring harness 13 is connected to the pull-out plate 4, and the other end is led out of the outside of the housing 16, and the wiring harness 13 is directly pulled by an external device to drive the baffle 2 to move.

[0050] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0051] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
