Description

Technical Field

[0001] This application relates to the field of equipment installation, specifically to a locking device. Background Technology

[0002] During equipment installation, screw fastening accounts for a large proportion of the workload, making the development of automated fastening devices an inevitable trend. Traditional fastening devices have certain limitations during fastening. For example, the suction components of traditional fastening devices cannot be height adjusted, causing the suction components to come into contact with the product surface during screw fastening, which can easily damage the product surface, affect the screw fastening effect, and in severe cases, damage the product. Summary of the Invention

[0003] In view of the above situation, this application provides a locking device to solve the above problems.

[0004] This application discloses a locking device for locking screws, comprising:

[0005] An electric screwdriver includes a body, an output shaft, and a bit. The body is connected to the output shaft, and the bit is connected to the output shaft. The body is used to drive the output shaft to rotate, and the output shaft is used to drive the bit to rotate.

[0006] An adsorption element has a first through hole extending along the extension direction of the screwdriver bit, the screwdriver bit passing through the first through hole, and an enlarged portion on the side of the adsorption element near the body. The adsorption element is used to adsorb the screw.

[0007] A connecting assembly includes a connector and an elastic member. The connector has a second through hole along the extension direction of the bit. One end of the connector is connected to the body, and the other end has a constriction opening. The suction member is slidably inserted into the constriction opening. The enlarged portion is located within the second through hole and divides the second through hole into a first air chamber and a second air chamber. The first air chamber is surrounded by the outer wall of the suction member, the inner wall of the connector, and the enlarged portion. The second air chamber is surrounded by the inner wall of the body, the inner wall of the connector, and the enlarged portion. The elastic member is located within the second air chamber, with one end abutting against the body and the other end abutting against the enlarged portion.

[0008] A pneumatic component, connected to the first air chamber, is used to input or discharge gas into the first air chamber and drive the adsorption component to move along the extension direction of the bit.

[0009] In one embodiment of this application, the connecting assembly further includes a guide member located in the first air chamber, the guide member being connected to the inner wall of the second through hole, the guide member having a guide groove corresponding to the inlet, and the adsorption member being sequentially inserted through the guide groove and the inlet.

[0010] In one embodiment of this application, the cross-sectional dimension of the guide groove along the direction perpendicular to the extension of the bit is smaller than the cross-sectional dimension of the enlarged portion.

[0011] In one embodiment of this application, the locking device further includes an air suction member, which is connected to the first through hole.

[0012] In one embodiment of this application, the adsorption member has a receiving groove, which is located at one end of the adsorption member away from the suction member. The first through hole penetrates the bottom of the receiving groove, and the inner diameter of the receiving groove is larger than the inner diameter of the first through hole.

[0013] In one embodiment of this application, the end of the bit away from the body is provided with a retaining part, which is used to retain the screw.

[0014] In one embodiment of this application, the outer wall of the enlarged portion is provided with an annular groove, and the enlarged portion is also provided with a first sealing member, which is sleeved on the annular groove.

[0015] In one embodiment of this application, a second sealing element is provided in the first through hole, the second sealing element is disposed between the constriction port and the guide element, and the second sealing element is sleeved on the adsorption element.

[0016] In one embodiment of this application, the outer wall of the connector is provided with an external thread, and the inner wall of the body is provided with an internal thread that is adapted to the external thread. The connector is threadedly connected to the body through the threaded engagement of the internal thread and the external thread.

[0017] In one embodiment of this application, the locking device further includes a limiting member, which is detachably connected to the connecting member and the body.

[0018] The aforementioned screw-locking device uses an adsorption component to draw in the screw and attach it to the screwdriver bit. The screw is then aligned with the target mounting area on the product. The main body drives the screwdriver bit to rotate, positioning the screw for installation. Once the screw is positioned in the target mounting area, an air source connected to the pneumatic component is activated, allowing air to flow into the first air chamber. At this point, the pressure in the first air chamber is greater than the pressure in the second air chamber. The enlarged portion slides into the second air chamber, and the elastic element is compressed and deformed, generating elastic force. The movement of the enlarged portion moves the adsorption component away from the product. Subsequently, the main body drives the screwdriver bit to rotate, completing the screw-locking process. Finally, the pneumatic component stops supplying air to the first air chamber, and the gas in the first air chamber is discharged. Under the elastic force of the elastic element itself, the elastic element returns to its original deformation, causing the enlarged portion to return to its original position for the next screw-locking cycle. Throughout the entire screw-locking process, the adsorption component does not contact the product, preventing damage to the product surface and protecting the product while improving assembly quality.

When a component is considered to be "set" on another component, it can be directly set on the other component or may also have a component that is centrally located.

[0056] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0057] Please see Figure 1 This application provides a locking device 100 for locking screws 200. The locking device 100 includes an electric screwdriver 10, an adsorption component 20, a connecting component 30, and a pneumatic component 40.

[0058] Please see Figure 2 and Figure 3 The electric screwdriver 10 includes a body 11, an output shaft 12, and a bit 13. The body 11 is connected to the output shaft 12, and the bit 13 is connected to the output shaft 12. The body 11 is used to drive the output shaft 12 to rotate, and the output shaft 12 is used to drive the bit 13 to rotate.

[0059] The adsorption member 20 has a first through hole 21 opened along the extension direction of the bit 13, and the bit 13 passes through the first through hole 21. The adsorption member 20 has an enlarged part 22 on the side near the body 11. The adsorption member 20 is used to adsorb the screw 200.

[0060] Please refer to this as well. Figure 4 The connecting component 30 includes a connector 31 and an elastic member 32. The connector 31 has a second through hole 310 along the extension direction of the bit 13. One end of the connector 31 is connected to the body 11, and the other end of the connector 31 has a constriction port 311. The adsorption member 20 is slidably inserted through the constriction port 311. The enlargement portion 22 is located in the second through hole 310 and divides the second through hole 310 into a first air chamber 3101 and a second air chamber 3102. The first air chamber 3101 is surrounded by the outer wall of the adsorption member 20, the inner wall of the connector 31, and the enlargement portion 22. The second air chamber 3102 is surrounded by the inner wall of the body 11, the inner wall of the connector 31, and the enlargement portion 22. The elastic member 32 is located in the second air chamber 3102. One end of the elastic member 32 abuts against the body 11, and the other end of the elastic member 32 abuts against the enlargement portion 22.

[0061] The pneumatic component 40 is connected to the first air chamber 3101. The pneumatic component 40 is used to input or discharge gas into the first air chamber 3101 and drive the adsorption component 20 to move along the extension direction of the bit 13.

[0062] During operation, the screw 200 is first sucked in by the suction member 20 and then sucked onto the bit 13. The screw 200 is then aligned with the target installation area on the product. The main body 11 is activated to drive the bit 13 to rotate and position the screw 200 for installation. After the screw 200 is positioned in the target installation area, the air source connected to the pneumatic component 40 is activated, and the pneumatic component 40 vents air into the first air chamber 3101. At this time, the pressure in the first air chamber 3101 is greater than the pressure in the second air chamber 3102. The expansion part 22 slides into the second air chamber 3102, and the elastic member 32 is squeezed and deformed to generate elastic force. The movement of the expansion part 22 drives the suction member 20 to move away from the product. Subsequently, the main body 11 drives the bit 13 to rotate and complete the fastening of the screw 200. Finally, the pneumatic component 40 stops supplying air to the first air chamber 3101, the gas in the first air chamber 3101 is discharged, and under the elastic force of the elastic component 32 itself, the elastic component 32 returns to its original position, causing the enlarged part 22 to return to its original position for the next screw fastening. During the entire screw fastening process, the adsorption component 20 will not come into contact with the product, preventing the adsorption component 20 from damaging the product surface, protecting the product while improving assembly quality.

[0063] In one embodiment of this application, the connecting component 30 further includes a guide 33, which is located in the first air chamber 3101. The outer wall of the guide 33 is fixedly disposed on the inner wall of the second through hole 310. The guide 33 has a guide groove 330, which is correspondingly disposed with the inlet 311. The adsorption component 20 is sequentially disposed through the guide groove 330 and the inlet 311.

[0064] Specifically, the adsorption element 20 passes through the guide groove 330, and the adsorption element 20 and the guide groove 330 are adapted to slide together, which effectively ensures that the adsorption element 20 maintains consistency in the direction of movement and does not move or deviate.

[0065] In one embodiment of this application, the cross-sectional dimension of the guide groove 330 is smaller than the cross-sectional dimension of the enlarged portion 22.

[0066] Understandably, the cross-sectional dimension of the guide groove 330 is smaller than that of the enlarged portion 22. The side of the guide groove 330 near the enlarged portion 22 can support the enlarged portion 22 and limit its movement.

[0067] Please combine Figure 4 In one embodiment of this application, the locking device 100 further includes an air suction member 50, which is connected to the first through hole 21 so that the end of the adsorption member 20 away from the air suction member 50 has a suction screw 200.

[0068] Please see Figure 5The adsorption member 20 has a receiving groove 23, which is located at the end of the adsorption member 20 away from the suction member 50. The first through hole 21 penetrates the bottom of the receiving groove 23, and the inner diameter of the receiving groove 23 is larger than the inner diameter of the first through hole 21.

[0069] Furthermore, the end of the bit 13 away from the body 11 is provided with a retaining part 1310, which is used to retain the screw 200.

[0070] Specifically, when the suction component 50 is connected to the external device, the suction component 50 performs suction, and through the communication with the first through hole 21, the end of the adsorption component 20 away from the main body 11 generates an attractive force. The adsorption component 20 automatically picks up the screw 200 and houses the nut part of the screw 200 in the receiving groove 23, and holds the groove of the nut part in the holding part 1310, thus completing the automatic picking up and holding of the screw 200.

[0071] Please see Figure 4 In one embodiment of this application, the outer wall of the enlarged portion 22 is provided with an annular groove 220, and the enlarged portion 22 is also provided with a first sealing member 221, which is sleeved in the annular groove 220.

[0072] In one embodiment of this application, a second sealing element 331 is provided in the first through hole 21. The second sealing element 331 is located between the inlet 311 and the guide element 33, and the second sealing element 331 is sleeved on the adsorption element 20.

[0073] In one embodiment of this application, the outer wall of the connector 31 is provided with an external thread 312, and the inner wall of the body 11 is provided with an internal thread 14 that is adapted to the external thread 312. The connector 31 is threadedly connected to the body 11 through the cooperation of the internal thread 14 and the external thread 312.

[0074] In one embodiment of this application, the locking device 100 further includes a limiting member 60, which is detachably connected to the connector 31 and the body 11.

[0075] Specifically, after the limiting member 60 is removed from the connector 31 and the body 11, the relative position between the connector 31 and the body 11 is adjusted by rotating the connector 31 with the cooperation of the external thread 312 and the internal thread 14. The limiting member 60 is then reinstalled on the connector 31 and the body 11 to fix the position of the connector 31 on the body 11. This allows for adjustment of the height of the adsorption member 20, thereby increasing the guiding function of the adsorption member 200 in the process of picking up the screw 200 and improving the pick-up yield.

[0076] Please see Figures 1-5With the suction component 50 connected to the external device, the suction component 50 performs suction, and through the communication with the second through hole 310 and the first through hole 21, the end of the adsorption component 20 away from the main body 11 generates an attractive force. The adsorption component 20 automatically picks up the screw 200 and houses the nut of the screw 200 in the receiving groove 23, and holds the groove of the nut in the holding part 1310, completing the automatic picking up and holding of the screw 200. Then, the screw 200 is aligned with the target installation area on the product, and the main body 11 is activated to drive the bit 13 to rotate and drive the screw 200 to be positioned and installed. After the screw 200 is positioned in the target installation area, the air source connected to the pneumatic component 40 is activated, and the pneumatic component 40 circulates air into the first air chamber 3101. At this time, the first air chamber 3101 is filled with air. The pressure is greater than the pressure in the second air chamber 3102. The expansion part 22 slides into the second air chamber 3102, and the elastic element 32 is squeezed and deformed to generate elastic force. Under the movement of the expansion part 22, the adsorption element 20 is moved to move away from the product. Then, the body 11 drives the bit 13 to rotate to complete the screw 200 fastening. Finally, the pneumatic component 40 stops air supply to the first air chamber 3101, the gas in the first air chamber 3101 is discharged, and under the elastic force of the elastic element 32 itself, the elastic element 32 returns to its original deformation, causing the expansion part 22 to return to its original position for the next screw 200 fastening. During the entire screw 200 fastening process, the adsorption element 20 will not come into contact with the product, preventing the adsorption element from damaging the product surface, protecting the product and improving assembly quality.

[0077] In addition, those skilled in the art may make other changes within the spirit of this application. Of course, all such changes made in accordance with the spirit of this application should be included within the scope of protection claimed in this application.
