This ensures the accuracy of the nut clamping by the clamping head, effectively preventing skew during nut clamping.

Description

Technical Field

[0001] This utility model relates to the field of gripper mechanism technology, specifically to an anti-skew nut gripper mechanism. Background Technology

[0002] Electric grippers generally have a drive mechanism and a clamping mechanism. The drive mechanism can drive the grippers to loosen or clamp the workpiece. Combination screws are a type of screw, generally consisting of a screw, a spring washer, and a flat washer, forming a three-part assembly. A bolt and washer insertion machine is a device used for fitting bolts and washers. Compared with manual fitting, it can effectively improve the production speed of combination screws. During the use of a bolt and washer insertion machine, a clamping device is usually required to hold the nut.

[0003] Currently, existing nut clamping mechanisms have certain shortcomings when clamping nuts. During the clamping process, the nuts are prone to tilting, which makes it difficult to connect the nuts to the bolts. Existing clamping mechanisms do not have a function to prevent tilting when clamping nuts. Therefore, we propose a tilt-preventing nut clamping mechanism. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an anti-tilting nut gripper mechanism, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-misalignment nut gripper mechanism, comprising a gripper base, an installation groove formed inside the bottom of the gripper base, a motor fixedly mounted on one side of the gripper base, a bidirectional lead screw fixedly mounted inside the installation groove at the output end of the motor, two sleeve blocks threaded onto the outer side of the bidirectional lead screw, a connecting plate fixedly mounted on the bottom of the sleeve blocks, a gripper head fixedly mounted on the bottom of the connecting plate, an installation plate fixedly mounted in the middle of the bottom of the gripper base, a guide cylinder fixedly mounted on the bottom of the installation plate, a sliding rod slidably mounted inside the bottom of the guide cylinder, a positioning plate fixedly mounted at one end of the sliding rod, an electromagnet formed inside the bottom of the positioning plate, a positioning cone fixedly mounted in the middle of the bottom of the positioning plate, a sliding groove formed on one side of the connecting plate, a slider slidably mounted inside the sliding groove, a connecting rod movably mounted on one side of the slider, and one end of the connecting rod movably connected to one side of the sliding rod.

[0006] Preferably, a damping rod is fixedly installed at the top inside the groove, one end of the damping rod is fixedly connected to the top of the slider, and a spring is installed on the outside of the damping rod, with the slider cooperating with the spring.

[0007] Preferably, a clamping groove is provided on one side of the gripper head, and an arc-shaped groove is provided in the middle of the gripper head, the arc-shaped groove cooperating with the positioning plate.

[0008] Preferably, the sleeve has a hole inside that mates with the bidirectional lead screw, and the sleeve is slidably connected to the inner wall of the bidirectional lead screw.

[0009] Preferably, the guide cylinder has a hole inside that mates with the slide rod.

[0010] Preferably, hinges that cooperate with the connecting rod are installed on one side of the slider and on both sides of the slider rod.

[0011] This utility model provides an anti-misalignment nut gripper mechanism, which has the following beneficial effects:

[0012] 1. This anti-skewing nut clamping mechanism, through the arrangement of a motor, a two-way lead screw, a sleeve block, a connecting plate, a clamping head, a mounting plate, a guide cylinder, a slide rod, a positioning plate, an electromagnet, a positioning cone, and a connecting rod, can push the positioning plate, electromagnet, and positioning cone downwards when the two connecting plates and the clamping head approach each other for clamping. This allows the positioning cone to be inserted into the nut hole for guidance. At the same time, the electromagnet generates magnetic force when energized, attracting the nut to the bottom of the positioning plate. Subsequently, the accuracy of the nut clamping by the clamping head is ensured, effectively preventing skewing during nut clamping.

[0013] 2. The anti-tilting nut gripper mechanism, through the setting of sliding groove, damping rod, spring and slider, can slowly push the positioning plate, connecting rod and slider upward as the nut is gradually tightened during installation, so as not to affect the connection between the nut and the bolt.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: an anti-tilting nut gripper mechanism, including a gripper base 1, with an installation groove 2 inside the bottom of the gripper base 1. A motor 3 is fixedly installed on one side of the gripper base 1, and a bidirectional lead screw 4 is fixedly installed inside the installation groove 2 at the output end of the motor 3. Two sleeve blocks 5 are threaded on the outer side of the bidirectional lead screw 4. The sleeve blocks 5 have holes that mate with the bidirectional lead screw 4 inside, and the sleeve blocks 5 are slidably connected to the inner wall of the bidirectional lead screw 4. A connecting plate 6 is fixedly installed at the bottom of the sleeve blocks 5, and a gripper head 7 is fixedly installed at the bottom of the connecting plate 6. A gripping groove 15 is opened on one side of the gripper head 7, and an arc-shaped groove 16 is opened in the middle of the gripper head 7. The arc-shaped groove 16 mates with a positioning plate 11. The bottom of the gripper base 1... A mounting plate 8 is fixedly installed in the middle, and a guide cylinder 9 is fixedly installed at the bottom of the mounting plate 8. A slide rod 10 is slidably installed inside the bottom of the guide cylinder 9. A hole is opened inside the guide cylinder 9 to cooperate with the slide rod 10. A positioning plate 11 is fixedly installed at one end of the slide rod 10. An electromagnet 12 is opened inside the bottom of the positioning plate 11. A positioning cone 13 is fixedly installed in the middle of the bottom of the positioning plate 11. A sliding groove 17 is opened on one side of the connecting plate 6. A slider 20 is slidably installed inside the sliding groove 17. A connecting rod 14 is movable on one side of the slider 20. One end of the connecting rod 14 is movably connected to one side of the slide rod 10. The diameter of the positioning plate 11 is smaller than the diameter of the nut to be clamped, so that when the gripper head 7 clamps the nut, it will not clamp the positioning plate 11.

[0021] A damping rod 18 is fixedly installed at the top inside the slide 17. One end of the damping rod 18 is fixedly connected to the top of the slider 20. A spring 19 is installed on the outside of the damping rod 18. The slider 20 cooperates with the spring 19. A hinge that cooperates with the connecting rod 14 is installed on one side of the slider 20 and both sides of the slide rod 10. The spring 19 has a large elastic force. When the two connecting plates 6 and the gripper head 7 approach each other, the elastic force of the spring 19 can press the slider 20 down to a fixed position and will not be pushed up by the connecting rod 14.

[0022] In summary, when using this anti-skew nut clamping mechanism, the positioning cone 13 is moved above the nut to be clamped. Then, the motor 3 is turned on to drive the bidirectional lead screw 4 to rotate. The bidirectional lead screw 4 drives the two sleeve blocks 5 to move towards the middle of the bidirectional lead screw 4 through the thread. This causes the connecting plate 6 and the clamping head 7 to move closer to the nut. At the same time, the connecting rod 14 pushes the slide rod 10 and the positioning plate 11 to move down, so that the positioning cone 13 is inserted into the hole of the nut and guided inside. At the same time, the electromagnet 12 is energized to generate magnetic force to attract the nut to the bottom of the positioning plate 11 for positioning. As the two connecting plates 6 and the clamping head 7 gradually move closer, the nut can be clamped and fixed, and the nut can be effectively prevented from being clamped skewed.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
