The following describes in detail the technical solutions provided by the embodiments of the present application with reference to the accompanying drawings.

The embodiment of the application provides a threaded connection locking device. Referring to fig. 1 to 11, a threaded connection locking apparatus 100 provided in an embodiment of the present application may include: the anti-fall assembly comprises a base 110, an anti-fall assembly 120, a linear actuator 130, a rotary actuator 140 and a screw connector 150.

The anti-falling component 120 is arranged on the base 110. The fall arrest assembly 120 may include a first fall arrest member 121 and a second fall arrest member 122 that can be moved toward and away from each other, with a space provided between the first fall arrest member 121 and the second fall arrest member 122.

The linear actuator 130 is disposed on the base 110. The linear driver 130 is in driving connection with the rotary driver 140, the rotary driver 140 is in driving connection with the screw member connector 150, and the screw member connector 150 is used for connecting the screw member 200 so as to drive the screw member 200 to move along with the screw member connector 150.

With the first fall preventing member 121 and the second fall preventing member 122 in a spaced apart state, the linear driver 130 is used to drive the screw connector 150 to rise and fall at the spaced space along with the rotary driver 140. In the case where the screw connector 150 is connected to the screw 200, the linear actuator 130 may drive the rotation actuator 140, the screw connector 150, and the screw 200 to be lifted and lowered together.

In the process of assembling and disassembling the screw connection 200, the rotation driver 140 is used to drive the screw connection 150 and the screw connection 200 to rotate, and the linear driver 130 is used to drive the rotation driver 140, the screw connection 150 and the screw connection 200 to ascend or descend, so that the screw connection 200 is screwed into a position where the screw connection 200 is to be installed, or the screw connection 200 is disassembled.

The first falling preventing member 121 and the second falling preventing member 122 in the approaching state serve to receive or clamp the screw connection member 200. In an embodiment, the threaded connection 200 may be prevented from falling by the first and second fall arrest members 121 and 122 clamping the threaded connection 200. In one embodiment, the first and second fall arrest members 121, 122 may be utilized to receive the threaded connection 200 such that the falling threaded connection 200 may be supported by the first and second fall arrest members 121, 122 to prevent the threaded connection 200 from being separated from the threaded connection 150.

In this way, in embodiments of the present application, after the screw connector 150 is coupled to the screw connector 200, the linear driver 130 may drive the screw connector 200 to move up with the screw connector 150. The first and second falling prevention pieces 121 and 122 can be switched to a close state to receive or clamp the screw 200 to prevent the screw 200 from falling during movement with the screw locking device 100.

In order to enable those skilled in the art to better understand the solution provided in the embodiments of the present application, the working principle of the threaded connector locking device 100 will be briefly described below by taking the threaded connector 200 as a cross-slot screw and the threaded connector 150 as a cross-shaped magnetic screwdriver.

The threaded connector lock 100 is first actuated to move to a position to supply the cross slot screw.

Further, referring to fig. 2 to 4, the first fall preventing member 121 and the second fall preventing member 122 are switched to a remote state, and the linear driver 130 drives the cross magnetic screwdriver head to descend to the first target position. Thereby utilizing the cross magnetic screwdriver head to magnetically adsorb the cross groove screw. Illustratively, the cross slot screw may be disposed vertically and the screw head of the cross slot screw may be disposed upwardly, which facilitates the cross magnetic screwdriver head to be coupled with the cross slot screw.

Further, referring to fig. 4 to 6, the linear driver 130 drives the cross magnetic head and the cross slot screw to rise to the second target position.

Further, referring to fig. 6 to 7, after the cross groove screw is raised to the second target position, the first and second falling preventive pieces 121 and 122 are switched to approach the device to clamp the cross groove screw, so as to prevent the cross groove screw from falling during movement with the screw locking device 100. Alternatively, the screw heads of the cross groove screws may be located above the upper surfaces of the first and second fall preventing members 121 and 122 to receive the cross groove screws using the first and second fall preventing members 121 and 122 to prevent the cross groove screws from falling during movement with the threaded connection locking device 100.

Further, the threaded connection locking apparatus 100 is driven to move to a position where a screw is required.

Further, referring to fig. 7 to 8, the first and second fall prevention pieces 121 and 122 are switched to a distant state to release the shielding of the falling path of the cross groove screw by the first and second fall prevention pieces 121 and 122.

Further, referring to fig. 8 and 9, the linear driver 130 drives the cross magnetic head and the cross slot screw to descend, and at the same time, the rotary driver 140 drives the cross magnetic head and the cross slot screw to rotate to screw the cross slot screw into a position where the screw needs to be driven.

It should be noted that the threaded connection locking device 100 provided in the embodiments of the present application may also be used for disassembling a threaded connection. Since the process of removing the threaded connection is the reverse of the process of locking the threaded connection, the process of removing the threaded connection will not be described further herein.

It is also noted that the threaded connection locking apparatus 100 may be driven by an operator or a robot to move to a position where a cross slot screw is supplied or a position where a screw is required, for example. Since the movement of the device to be moved is driven by the manipulator in the prior art, the working principle of the movement of the threaded connection locking device 100 driven by the manipulator will not be described in detail in the embodiments of the present application.

In addition, the lifting and lowering of the member using the linear actuator 130 is also known in the art, and thus, the working principle of lifting and lowering the rotary actuator 140 and the screw connector 150 using the linear actuator 130 will not be described in detail in the embodiments of the present application. The rotation of the driving member by the rotation driver 140 is also known in the art, and thus, the working principle of the driving of the screw connector 150 by the rotation driver 140 will not be described in detail in the embodiments of the present application.

In order to improve the performance of the threaded connection locking device, a further improved threaded connection locking device is provided below on the basis of the threaded connection locking device provided above.

In some embodiments, the threaded connection locking apparatus 100 may also include a detector 160. The detector 160 is used to detect whether the screw connection 200 is located between the first fall preventing member 121 and the second fall preventing member 122.

Thus, referring to fig. 6 and 7, after the screw connector 150 completes the process of obtaining the screw 200, the screw connector 150 may be raised to a preset position. At this point, the detector 160 may begin to operate. In the event that the detector 160 detects that the threaded connection 200 is located between the first fall arrest member 121 and the second fall arrest member 122, it may be determined that the threaded connection 200 was successfully obtained by the threaded connection 150. So that the first fall preventing member 121 and the second fall preventing member 122 can be switched to the approaching state to receive or clamp the screw connection member 200. In the event that the detector 160 does not detect the threaded connection 200, it may be determined that the threaded connection 200 was not successfully obtained by the threaded connection 150. Thus, the screw connector 150 may be driven downward to again acquire the screw 200 from the position where the cross-slot screw is supplied.

Referring to fig. 6, in some embodiments, the detector 160 may include an optical signal transmitter 161 and an optical signal receiver 162. The optical signal transmitter 161 is disposed on the first falling preventing member 121, the optical signal receiver 162 is disposed on the second falling preventing member 122, and the optical signal transmitter 161 is disposed opposite to the optical signal receiver 162 so as to emit an optical signal toward the optical signal receiver 162. Illustratively, the optical signal transmitter 161 may be a laser transmitter and the optical signal receiver 162 may be a photosensor.

Thus, in connection with fig. 6, in the case where the screw connector 200 is located between the first fall preventing member 121 and the second fall preventing member 122, the light signal emitted from the light signal emitter 161 toward the light signal receiver 162 may be blocked by the screw connector 200, so that the light signal receiver 162 will not receive the light signal. Thus, it can be determined whether the screw connection member 200 is positioned between the first fall preventing member 121 and the second fall preventing member 122 based on the manner in which the optical signal receiver 162 receives the optical signal.

In other embodiments, the detector 160 may be any other sensor capable of detecting whether a part is located at a specified position in the prior art, and this is not illustrated here.

Referring to fig. 10 and 11, in some embodiments, the protruding end of the first fall preventing member 121 is provided with first protrusions 1211 and second protrusions 1212 that are spaced apart. The first protruding portion 1211 is provided with a first through hole, the second protruding portion 1212 is provided with a first mounting hole, and the optical signal transmitter 161 is disposed in the first mounting hole and faces the first through hole.

The protruding end of the second fall preventing member 122 is provided with a third protruding portion 1221 and a fourth protruding portion 1222 that are spaced apart. The third protruding portion 1221 has a second through hole opposite to the first through hole, the fourth protruding portion 1222 has a second mounting hole, and the optical signal receiver 162 is disposed in the second mounting hole and faces the second through hole.

In this way, in the case where the screw connection member 200 is not present between the first fall preventing member 121 and the second fall preventing member 122, the optical signal emitted from the optical signal emitter 161 can be sequentially directed to the optical signal receiver 162 through the first and second penetration holes.

Referring to fig. 10 and 11, in some embodiments, the first fall arrest member 121 is provided with a first recess 1213, the first recess 1213 being recessed in a direction away from the second fall arrest member 122. The second fall preventing piece 122 is provided with a second concave portion 1223, and the second concave portion 1223 is concave in a direction away from the first concave portion 1213. Referring to fig. 7, the first recess 1213 and the second recess 1223 form a receiving area for receiving the threaded connection member 200 in a state where the first fall preventing member 121 and the second fall preventing member 122 are in close proximity.

In some embodiments, threaded connection 200 is clamped between first recess 1213 and second recess 1223; and/or the upper surfaces of the first recess 1213 and the second recess 1223 are received under the threaded connection 200. In this way, the threaded connection 200 can be prevented from falling.

Referring to fig. 10 and 11, in some embodiments, the fall arrest assembly 120 can further include a grip driver 123. The grip driver 123 may include a first moving member 1231 and a second moving member 1232, the first and second moving members 1231 and 1232 being capable of moving toward and away from each other. The first moving member 1231 is drivingly connected to the first fall preventing member 121, and the second moving member 1232 is drivingly connected to the second fall preventing member 122.

Illustratively, the grip actuator 123 may be a pneumatic finger. The pneumatic finger is also called a pneumatic clamping jaw or a pneumatic clamping finger, and is an executing device for clamping or grabbing a workpiece by using compressed air as power. In this way, the first fall preventing member 121 and the second fall preventing member 122 can be driven to switch between the approaching state and the separating state by the pneumatic finger.

Of course, in other embodiments, the clamping driver 123 may be any other driver capable of driving the first fall preventing member 121 and the second fall preventing member 122 to switch between the close state and the far state in the prior art, which is not described herein.

In some embodiments, the threaded connection 200 may include a screw, or a nut. The screw connector 150 may include a magnetic bit or a magnetic sleeve. For example, where the threaded connection 200 is a hexagonal screw, the threaded connection connector 150 may be an internal hexagonal magnetic sleeve.

Referring to fig. 1, in some embodiments, the threaded connection locking apparatus 100 may further include a slide assembly 170 and a mount 180. The slide assembly 170 may include a slide rail and a carriage that are slidably coupled. The sliding rail may be disposed on the base 110, the sliding base may be connected to the support 180, and the rotary driver 140 may be disposed on the support 180. The linear actuator 130 is drivingly connected to the support 180. In this way, the linear driver 130 can be used to drive the support 180 to slide relative to the base 110, so as to drive the rotary driver 140 disposed on the support 180 to lift.

The linear driver 130 may be a linear motor, a cylinder, a hydraulic cylinder, or the like capable of outputting a linear driving force, for example. The linear driver 130 may also include a device capable of outputting a rotational driving force, such as a rotary electric machine, an air motor, or a hydraulic motor, and a transmission mechanism capable of converting a rotational motion into a linear motion, such as a screw-nut transmission mechanism, for example.

The rotary driver 140 may be a device capable of outputting a rotational driving force, such as a rotary electric machine, an air motor, or a hydraulic motor, for example. Alternatively, the rotary driver 140 may be a tool for removing screws and nuts, such as an electric screwdriver, a pneumatic wrench, or the like.

The embodiment of the application provides a threaded connection locking device. Referring to fig. 12 and 13, the threaded connection locking apparatus 10 provided in an embodiment of the present application may include: a driving device 300 and any of the threaded connection locking devices 100 provided in the embodiments of the present application. The driving device 300 is in driving connection with the screw locking device 100 to drive the screw locking device 100 to move. Illustratively, the drive device 300 may be a robotic arm.

In some embodiments, the threaded connection locking apparatus 10 may also include an industrial camera 400. The industrial camera 400 is disposed on the base 110. In this way, the position of the screw locking device 100 may be determined using the industrial camera 400 such that the driving device 300 can drive the screw locking device 100 to more accurately move to the position of the supply screw 200 or to the position where the screw needs to be screwed. Since the positioning by the industrial camera 400 is the prior art, the working principle of driving the screw locking device 100 to the target position by the auxiliary driving device 300 of the industrial camera 400 will not be described in detail herein.

In some embodiments, the threaded connection locking apparatus 10 may further include a threaded connection supply 500. The screw supply device 500 may be used to supply the screw 200 so that the screw connector 150 can be accurately connected with the screw 200.
