A locking device

Abstract

This utility model provides a screw fastening device. By opening a bit channel and a screw channel in the screw fastening nozzle, and connecting the lower end of the screw channel to the bit channel, when screws need to be fastened to the product, the screw fastening nozzle can be moved above the screw hole and aligned. Then, the screw is fed into the screw channel of the screw fastening nozzle. Finally, the screw is driven by the bit to dislodge from the outlet of the bit channel. At the same time, the outlet is switched from a closed state to an open state. Compared with the existing dual-level drive for fastening and unloading, this application not only has a simple structure, but also enables rapid feeding of screws after the screw fastening nozzle is positioned with the screw hole, and the screw is fastened into the product by the bit. Furthermore, due to the presence of the screw fastening nozzle, this application can also fasten screws in relatively narrow spaces. By setting multiple screw fastening nozzles on the nozzle plate, multiple screws can be fastened even when the distance between adjacent screw holes is small.

Description

Technical Field

[0001] This utility model relates to the field of automated assembly, specifically a locking device. Background Technology

[0002] Threaded connections are a widely used method of detachable fastening. To reduce labor input, more and more manufacturing companies are adopting automated machines such as screw tightening machines and fastening devices to replace the traditional manual screw tightening process.

[0003] Currently, existing screw fastening devices all use a drive assembly to move the screw fastening assembly downwards to pick up the screws. Then, the drive assembly moves the screw fastening assembly further downwards to the fastening position on the product to be fastened. Finally, the screw fastening cylinder is activated to drive the electric screwdriver to press down and fasten the screws into the product. Although this can achieve automatic screw picking and fastening, the current screw fastening devices require a two-level drive, resulting in an excessively large overall size. This excessive size makes it impossible to fasten all screws on the product simultaneously. Utility Model Content

[0025] When the first groove and the second groove are in contact with the lower ends of the first locking clamp and the second locking clamp, they form a second channel and a closed outlet for the screw shank to pass through and restrict the screw head from passing through.

[0026] Preferably, the bit transmission component includes: a rotating shaft, a bushing, a fastening nut, and a bit mounting sleeve;

[0027] The rotating shaft is mounted on the bit fixing plate via a bushing, and the upper end of the rotating shaft is used for transmission connection with the power component;

[0028] The upper end of the bit mounting sleeve is connected to the lower end of the rotating shaft;

[0029] The lower end of the bit mounting sleeve has an insertion interface for inserting the bit;

When the discharge port is in the open state, it is used to disengage the screw from the discharge port. The aforementioned locking device, by opening a bit channel and a screw channel in the locking nozzle and connecting the lower end of the screw channel to the bit channel, allows the locking nozzle to be moved above and aligned with the screw hole when screws need to be locked onto the product.

Compared to existing dual-level drive methods for locking and unloading, this application not only has a simpler structure but also enables rapid feeding (of screws) after the locking nozzle is positioned with the screw hole, and the screw is locked into the product by the bit. Furthermore, due to the presence of the locking nozzle, this application can also lock screws in relatively narrow spaces. By setting multiple locking nozzles on the locking nozzle plate, multiple screws can be locked into the product even when the distance between adjacent screw holes is small.

[0046] The components include: a locking nozzle 1, a bit channel 11, a screw channel 12, a discharge port 13, a first locking nozzle clamp 14, a first groove 141, a second locking nozzle clamp 15, a second groove 151, a connecting block 16, a first channel 161, a first elastic element 17, a second elastic element 18, a second channel 19, a limiting structure 20, a first limiting protrusion 201, and a second limiting protrusion 202; a bit transmission component 2, a rotating shaft 21, a bushing 22, a fastening nut 23, a bit mounting sleeve 24, a third elastic element 25, a limiting pin 26, a connecting nut 27, and a wear-resistant plate 28; a bit fixing plate 3; a locking nozzle plate 4, a positioning post 41, and a limiting block 42; a precision positioning assembly 5; a lifting mechanism 6; and a bit 7. Detailed Implementation

[0047] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0048] This utility model embodiment provides a locking device, see [link]. Figure 1 and combined Figures 2 to 7 The locking device includes: a locking nozzle 1, a bit transmission component 2, a bit fixing plate 3, and a locking nozzle plate 4;

[0049] The bit fixing plate 3 is movably positioned above the locking plate 4;

[0050] Lock nozzle 1 is mounted on lock nozzle plate 4;

[0051] The bit drive component 2 is disposed on the bit fixing plate 3. The lower end of the bit drive component 2 near the locking plate 4 is used to fix the bit 7, and the upper end of the bit drive component 2 away from the locking plate 4 is used to connect with the power component for transmission.

[0052] The locking nozzle 1 has a bit channel 11 for the bit 7 to pass through and a screw channel 12 for the screw to pass through. The screw channel 12 is connected to the bit channel 11 and is set at a preset angle. The bit channel 11 passes through the locking nozzle 1 in a vertical direction.

[0053] The lower end of the locking nozzle 1, away from / near the locking nozzle plate 4, is provided with a discharge port 13 that connects to the bit channel 11. The discharge port 13 has an open state and a closed state. When the discharge port 13 is in the closed state, it is used to restrict the screw to be located in the discharge port 13. When the discharge port 13 is in the open state, it is used to allow the screw to be disengaged from the discharge port 13.

[0054] It should be noted that the lower end of the screw channel 12 in this application is connected to the bit channel 11. The screw enters through the upper end of the screw channel 12 and enters the bit channel 11 along the screw channel 12 under its own gravity. Finally, the screw enters the discharge port 13. If the discharge port 13 is in a closed state, the discharge port 13 restricts the screw from passing through the discharge port 13 through hole. Even if the screw is located at the discharge port 13, if the discharge port 13 is in an open state, the screw can be dislodged from the discharge port 13.

[0055] It should also be noted that this application uses a bit channel 11 for the bit 7 to pass through. The bit 7 moves downward and, after it comes into contact with the screw, it continues to move the screw downward. At this time, the bit 7 can gradually switch the discharge port 13 from a closed state to an open state until the screw is disengaged from the discharge port 13. After the bit 7 drives the screw to complete the locking work, the bit 7 moves upward along the bit channel 11, and the discharge port 13 switches from an open state to a closed state, so that the screw that enters can be placed in the discharge port 13.

[0056] In this embodiment of the utility model, the bit fixing plate 3 is movably disposed above the locking plate 4, the locking nozzle 1 is disposed on the locking plate 4, the bit transmission component 2 is disposed on the bit fixing plate 3, the bit transmission component 2 is fixed with the bit 7 near the lower end of the locking plate 4, and the bit transmission component 2 is connected to the power component for transmission away from the upper end of the locking plate 4. The locking nozzle 1 has a bit channel 11 for the bit 7 to pass through and a screw channel 12 for the screw to pass through, and the screw channel 12 is connected to the bit channel 11 and set at a preset angle, so that the bit channel 11 passes through the locking nozzle 1 vertically. The lower end of the locking nozzle 1 away from / near the locking plate 4 is provided with a discharge port 13 that communicates with the bit channel 11. The discharge port 13 has an open state and a closed state. When the discharge port 13 is in the closed state, it is used to restrict the screw to be located in the discharge port 13. When the discharge port 13 is in the open state, it is used to disengage the screw from the discharge port 13. By using the aforementioned locking device, a bit channel 11 and a screw channel 12 are opened in the locking nozzle 1, and the lower end of the screw channel 12 is connected to the bit channel 11. When it is necessary to lock screws onto the product, the locking nozzle 1 can be moved above the screw hole and aligned. Then, the screw is fed into the screw channel 12 of the locking nozzle 1. Finally, the screw is driven out from the discharge port 13 of the bit channel 11 by the bit 7. At the same time, the discharge port 13 is switched from a closed state to an open state. Compared with the existing dual-level drive to achieve locking and unloading, the structure of this application is not only simple, but also enables rapid feeding (screws) after the locking nozzle 1 is positioned with the screw hole. The screw is then locked into the product by the bit 7. Furthermore, due to the presence of the locking nozzle 1, this application can also lock screws in relatively narrow spaces. By setting multiple locking nozzles 1 on the locking nozzle plate 4, multiple screws can be locked in when the distance between adjacent screw holes is small.

[0057] Preferably, the thickness of the locking nozzle 1 is 11mm.

[0058] It should be noted that the thickness of the locking mouth 1 can be set to 11mm, 15mm, or other thicknesses, and is not limited to these. Therefore, those skilled in the art can make the selection based on the screw channel 12 and the bit channel 11 and the application scenario. This application does not make any specific limitations.

[0059] Specifically, the locking mouth 1 includes: a first locking mouth clamp 14, a second locking mouth clamp 15, a connecting block 16, a first elastic element 17, and a second elastic element 18;

[0060] The connecting block 16 has a first channel 161 in the vertical direction for the bit 7 to pass through;

[0061] The first locking clamp 14 and the second locking clamp 15 are rotatably disposed on both sides of the connecting block 16. The lower end of the first locking clamp 14 and the lower end of the second locking clamp 15 fit together to form a second channel 19 and a closed discharge port 13. The second channel 19 connects to the first channel 161 to form a bit channel 11.

[0062] The screw channel 12 is disposed in the second locking jaw clamp 15 and communicates with the second channel 19;

[0063] The first elastic element 17 is disposed between the first locking clamp 14 and the connecting block 16;

[0064] The second elastic element 18 is disposed between the second locking clamp 15 and the connecting block 16.

[0065] It should be noted that the first locking clamp 14 and the second locking clamp 15 are rotatably mounted on both sides of the connecting block 16, thus forming a rocker structure. A first elastic element 17 is positioned between the first locking clamp 14 and the connecting block 16, and a second elastic element 18 is positioned between the second locking clamp 15 and the connecting block 16. Under the action of the first elastic element 17 and the second elastic element 18, the lower ends of the first locking clamp 14 and the second locking clamp 15 are brought together to form a second channel 19 and a closed discharge port 13. The second channel 19 connects to the first channel 161 to form a batch... In the head channel 11, when the screw passes through the discharge port 13 under the action of the bit 7, the lower ends of the first locking clamp 14 and the second locking clamp 15 will gradually open, that is, gradually switch from the closed state to the open state. When the screw is dislodged from the discharge port 13 and the screw is locked in, the bit 7 moves upward. At this time, the lower end of the first locking clamp 14 gradually approaches the second locking clamp 15 under the action of the first elastic element 17, and at the same time, the lower end of the second locking clamp 15 gradually approaches the first locking clamp 14 under the action of the second elastic element 18, until the discharge port 13 is in the closed state. At this time, the screw can be fed again through the screw channel 12.

[0066] Preferably, the first elastic element 17 and the second elastic element 18 are springs.

[0067] It should be noted that the first elastic element 17 and the second elastic element 18 can be springs, sheet springs, or other components with elastic deformation. Those skilled in the art can choose according to their needs.

[0068] Preferably, the clamping angle of the first locking jaw 14 and the second locking jaw 15 is between 2.6° and 3.0°.

[0069] It should be noted that setting the clamping angle of the first locking clamp 14 and the second locking clamp 15 between 2.6° and 3.0° can not only prevent the first locking clamp 14 and the second locking clamp 15 from affecting other parts on the product to be locked when they move, but also ensure that the screw can be removed from the discharge port 13.

[0070] Specifically, the second channel 19 is provided with a limiting structure 20 to restrict the passage of screws;

[0071] The limiting structure 20 is located above the connection between the second channel 19 and the first channel 161.

[0072] It should be noted that the diameter of the screw head is usually larger than the diameter of the bit 7. Therefore, a limiting structure 20 for restricting the screw passage is provided in the second channel 19 formed by the lower end of the first locking clamp 14 and the lower end of the second locking clamp 15. The limiting structure 20 is located above the connection between the second channel 19 and the first channel 161, which can effectively prevent the bit 7 from driving the screw out of the bit channel 11.

[0073] It is worth noting that after setting the limiting structure 20 in the second channel 19, the size of the second channel 19 is smaller than the screw head size and larger than the diameter of the bit 7. Therefore, after setting the limiting structure 20, the second channel 19 can only ensure that the bit 7 can pass through.

[0074] Furthermore, the limiting structure 20 includes: a first limiting protrusion 201 and / or a second limiting protrusion 202;

[0075] The first limiting protrusion 201 is disposed on the first locking mouth clamp 14;

[0076] The second limiting protrusion 202 is disposed on the second locking jaw clamp 15.

[0077] It should be noted that the screw can be restricted from passing through by setting a first limiting protrusion 201 on the first locking jaw clamp 14, or by setting a second limiting protrusion 202 on the second locking jaw clamp 15, or by setting both the first limiting protrusion 201 on the first locking jaw clamp 14 and the second limiting protrusion 202 on the second locking jaw clamp 15. Those skilled in the art can choose according to their needs. In this application, it is preferred to set both the first limiting protrusion 201 on the first locking jaw clamp 14 and the second limiting protrusion 202 on the second locking jaw clamp 15 to restrict the screw from passing through.

[0078] Furthermore, a first groove 141 is vertically formed at the lower end of the first locking jaw 14;

[0079] The lower end of the second locking clamp 15 is vertically provided with a second groove 151;

[0080] When the first groove 141 and the second groove 151 are in contact with the lower end of the first locking clamp 14 and the lower end of the second locking clamp 15, they form a second channel 19 and a closed outlet 13 for the screw shank to pass through and restrict the screw head from passing through.

[0081] It should be noted that this application can form a second channel 19 and a closed outlet 13 by vertically opening a first groove 141 at the lower end of the first locking clamp 14 and vertically opening a second groove 151 at the lower end of the second locking clamp 15, so that the first groove 141 and the second groove 151 are in contact with the lower ends of the first locking clamp 14 and the second locking clamp 15. Alternatively, the first groove 141 can be vertically opened at the lower end of the first locking clamp 14, so that the first groove 141 is in contact with the lower ends of the first locking clamp 14 and the second locking clamp 15, so that the second groove 151 is vertically opened at the lower end of the second locking clamp 15, so that the second groove 151 is in contact with the lower ends of the first locking clamp 14 and the second locking clamp 15, so that the second channel 19 and the closed outlet 13 are in contact with the lower ends of the second locking clamp 15. Those skilled in the art can choose according to their needs.

[0082] It should also be noted that when the lower end of the first locking clamp 14 is in contact with the lower end of the second locking clamp 15, the discharge port 13 can be positioned by the screw head of the limiting screw passing through, or by the screw shaft of the limiting screw passing through. Those skilled in the art can change the size of the discharge port 13 in the closed state according to their needs.

[0083] It is worth noting that when the discharge port 13 is closed, the lower end of the first locking clamp 14 can be attached to the lower end of the second locking clamp 15, or there can be a certain gap. Those skilled in the art can set it according to their needs.

[0084] Preferably, the first groove 141 and / or the second groove 151 are arc structures.

[0085] It should be noted that the first groove 141 and the second groove 151 can be arc structures or other types of structures (such as polygons, squares, etc.), and those skilled in the art can choose according to their needs.

[0086] Specifically, the bit transmission component 2 includes: a rotating shaft 21, a bushing 22, a fastening nut 23, and a bit mounting sleeve 24;

[0087] The rotating shaft 21 is mounted on the bit fixing plate 3 via the bushing 22, and the upper end of the rotating shaft 21 is used for transmission connection with the power component;

[0088] The upper end of the bit mounting sleeve 24 is connected to the lower end of the rotating shaft 21;

[0089] The lower end of the bit mounting sleeve 24 has an insertion interface for inserting the bit 7;

[0090] The fastening nut 23 is located at the lower end of the bit mounting sleeve 24, and the fastening nut 23 is used to prevent the bit 7 from coming out of the insertion interface.

[0091] It should be noted that the rotating shaft 21 is mounted on the bit fixing plate 3 via the bushing 22, and the upper end of the rotating shaft 21 is connected to the power component for transmission. The upper end of the bit mounting sleeve 24 is connected to the lower end of the rotating shaft 21. The lower end of the bit mounting sleeve 24 is provided with an insertion interface for inserting the bit 7. The fastening nut 23 is located at the lower end of the bit mounting sleeve 24. The fastening nut 23 is used to restrict the bit 7 from coming out of the insertion interface. Thus, the bit 7 can rotate under the drive of the power component. Furthermore, by rotating the fastening nut 23, the bit 7 can be locked and unlocked. Therefore, this application can also replace the corresponding bit 7 according to the type of screw head.

[0092] Furthermore, the locking device also includes: a third elastic element 25 and a limiting pin 26 disposed within the insertion interface;

[0093] The third elastic element 25 is disposed between the limiting pin 26 and the rotating shaft 21.

[0094] It should be noted that by setting a third elastic element 25 and a limiting pin 26 inside the insertion interface, and positioning the third elastic element 25 between the limiting pin 26 and the rotating shaft 21, the third elastic element 25 can provide a certain buffer when the screwdriver bit 7 drives the screw into the screw hole during the screw fastening process. The elastic restoring force provided by the third elastic element 25 can tighten the screw. By setting the limiting pin 26, the excessive deformation of the third elastic element 25 can be avoided, thus effectively extending the service life of the third elastic element 25.

[0095] Preferably, the locking device further includes: a connecting nut 27 and a wear-resistant plate 28 with an annular structure;

[0096] The connecting nut 27 fixes the bushing 22 to the bit fixing plate 3 via the wear-resistant plate 28.

[0097] It should be noted that the lower end of the bushing 22 of this application is provided with a limiting protrusion ring to restrict the bushing 22 from passing through the mounting hole of the bit fixing plate 3, and the wear-resistant plate 28 is set inside the bit fixing plate 3. The connecting nut 27 is threadedly engaged with the upper end of the bushing 22 to fix the bushing 22 on the bit fixing plate 3.

[0098] Preferably, the outer wall of the end of the rotating shaft 21 away from the power component is provided with a limiting member, and the limiting member and the bit fixing plate 3 are fitted with a wear-resistant plate 28 with an annular structure.

[0099] It should be noted that by providing a limiting member on the outer wall of the end of the rotating shaft 21 away from the power component, and by fitting a wear-resistant plate 28 with an annular structure on the limiting member and the bit fixing plate 3, the contact wear between the rotating shaft 21 and the bit fixing plate 3 can be avoided, effectively improving the service life of the rotating shaft 21, and thus improving the service life of the locking device.

[0100] Preferably, the third elastic element 25 is a spring.

[0101] It should be noted that the third elastic element 25 can be a spring or other components with elastic deformation, and those skilled in the art can choose according to their needs.

[0102] Specifically, multiple locking cylinders 1 are arranged along the edge of the locking cylinder 1 fixing plate;

[0103] Multiple bit drive components 2 are arranged along the edge of the bit fixing plate 3, wherein multiple locking nozzles 1 correspond one-to-one with multiple bit drive components 2.

[0104] It should be noted that by setting multiple locking nozzles 1 along the edge of the locking nozzle 1 fixing plate and setting multiple bit transmission components 2 along the edge of the bit fixing plate 3, and by having multiple locking nozzles 1 and multiple bit transmission components 2 correspond one-to-one, multiple screw holes can be locked simultaneously, which effectively improves the product assembly efficiency.

[0105] Furthermore, the locking device also includes a precision positioning component 5 disposed below the locking plate 4, the precision positioning component 5 being used to fix the target part.

[0106] It should be noted that by setting a precision positioning component 5 for fixing the target part and placing the precision positioning component 5 below the locking plate 4, the product to be locked (i.e. the target part) can be accurately fixed, thereby ensuring that the discharge port 13 of the locking nozzle 1 can be aligned with the screw hole, which greatly improves the assembly efficiency of the product.

[0107] Furthermore, the locking device also includes a lifting mechanism 6 located below the precision positioning component 5, which is used to drive the precision positioning component 5 to move up and down.

[0108] It should be noted that by setting up a lifting mechanism 6 to drive the precision positioning component 5 to move up and down, when it is necessary to lock the product to be locked, the lifting mechanism 6 drives the precision positioning component 5 to descend, so that the precision positioning component 5 and the locking nozzle 1 are reserved with a large space, which makes it convenient to fix the product to be locked onto the precision positioning component 5. When the product to be locked is fixed, the lifting mechanism 6 drives the precision positioning component 5 to rise, reducing the distance between the product to be locked and the locking nozzle 1. Then, when the screwdriver bit 7 drives the screw to lock, the screw can be quickly locked into the product.

[0109] Preferably, the locking device further includes a frame and a servo drive assembly.

[0110] The frame is located on one side of the locking device, and the servo drive assembly is located on the top of the frame. The servo drive assembly is connected to the bit transmission component 2.

[0111] It should be noted that the servo drive component in this application is a power component, which can drive the bit transmission component 2 to rotate.

[0112] Preferably, the locking device further includes: a positioning post 41 and a limiting block 42 disposed on the locking plate 4;

[0113] The positioning post 41 and the limiting block 42 are both located below the locking plate 4.

[0114] It should be noted that by setting the positioning post 41, the locking nozzle 1 can be quickly aligned with the screw hole of the product to be locked. The limiting block 42 can prevent the product to be locked from rising too much when the lifting mechanism 6 lifts the product to be locked, thus avoiding collision with the locking nozzle 1 and damage to the product parts.
