[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0023] like Figure 1-5 As shown, an anti-loosening component of a handling tool includes a lifting seat 21 and a clamping claw 22 horizontally slidably arranged thereon, and an anti-loosening component 3 is arranged on the clamping claw 22. The anti-loosening component 3 includes a rotating frame 31 and a mounting seat 32 arranged on the rotating frame 31. The rotating frame 31 is flipped and arranged on the clamping claw 22, and the rotating axis of the rotating frame 31 is horizontal and perpendicular to the sliding direction of the clamping claw 22. The mounting seat 32 is provided with a flexible locking strip 33. The clamping claw 22 is driven to slide close to the clamped cylindrical workpiece, and the rotating frame 31 is driven to flip close to the upper end of the cylindrical workpiece so that the rotating frame 31 and the mounting seat 32 are inclined toward the cylindrical workpiece, and the flexible locking strip 33 is deformed to contact the circumferential side of the cylindrical workpiece.

[0024] Specifically, Figure 1 As shown, it also includes a handling robot body, which includes a base frame 11, on which a rotating seat 13 is rotatably arranged through a rotating component 12, and a lifting seat 21 is vertically slidably arranged on the rotating seat 13, and a clamping claw 22 is horizontally slidably arranged on the lifting seat 21 to clamp the workpiece, wherein the clamping claw 22 can be driven by a telescopic cylinder, an electric push rod or a motor in conjunction with a gear set and a rack to realize the sliding of the clamping claw 22, or it can be replaced by other driving mechanisms known to those skilled in the art that can drive the clamping claw 22 to slide. It should be noted that the rotating component 12 is common knowledge known to those skilled in the art and will not be elaborated here.

[0025] The rotating frame 31 is flipped and provided with a clamping claw 22. The clamping claw 22 is provided with a driving motor 37 to drive the flipping of the rotating frame 31. The mounting seat 32 is provided on the rotating frame 31 to flip synchronously with the rotating frame 31. When the clamping claws 22 approach each other to clamp the cylindrical workpiece, the rotating frame 31 and the mounting seat 32 thereon are driven to flip close to the upper end of the cylindrical workpiece, so that the mounting seat 32 is tilted toward the cylindrical workpiece, and the flexible locking strip 33 is flipped close to the upper end of the cylindrical workpiece to abut against the circumferential side of the cylindrical workpiece and deform. The push and contact of the flexible locking strip 33 on the upper end of the cylindrical workpiece can utilize friction to further axially lock the cylindrical workpiece, while the upper end of the cylindrical workpiece is pushed, and the lower end is reversely tightly abutted and pressed on the clamping claw 22, so that the cylindrical workpiece has a tendency to rotate and tilt relative to the clamping claw 22, thereby avoiding the problem that the cylindrical workpiece is easy to slide axially and fall off the clamping claw 22, thereby improving the clamping stability.

[0026] In the above technical scheme, the anti-loosening component 3 on the clamping claw 22 is utilized. When the clamping claws 22 are close to each other to clamp the cylindrical workpiece, the rotating frame 31 and the mounting seat 32 thereon are driven to flip close to the upper end of the cylindrical workpiece, so that the mounting seat 32 is tilted toward the cylindrical workpiece, and the flexible locking strip 33 is flipped close to the upper end of the cylindrical workpiece to abut against the circumferential side of the cylindrical workpiece and deform. The push and contact of the flexible locking strip 33 on the upper end of the cylindrical workpiece can utilize friction to further axially lock the cylindrical workpiece, while the upper end of the cylindrical workpiece is pushed, and the lower end is reversely tightly abutted and pressed on the clamping claw 22, so that the cylindrical workpiece has a tendency to rotate and tilt relative to the clamping claw 22, thereby avoiding the problem that the cylindrical workpiece is easy to slide axially and fall off the clamping claw 22, thereby improving the clamping stability.

[0027] As a further embodiment of the present invention, a sliding portion 321 is provided on the mounting seat 32 , a sliding groove 311 is provided on the rotating frame 31 , and the sliding portion 321 is slidably disposed in the sliding groove 311 to enable the mounting seat 32 to slide and retract relative to the rotating frame 31 .

[0028] Specifically, Figure 4 As shown, the sliding portion 321 of the mounting seat 32 is slidably disposed in the sliding groove 311 of the rotating frame 31 so that the mounting seat 32 can slide relative to the rotating frame 31, and then the sliding of the mounting seat 32 can change the distance between the flexible locking strip 33 on the mounting seat 32 and the clamping claw 22, thereby facilitating the flexible locking strip 33 to limit and lock cylindrical workpieces of different lengths, thereby improving the applicability and stability of the device.

[0029] As an embodiment further provided by the present invention, a threaded drive rod 34 and an adjustment rod 35 are rotatably provided on the rotating frame 31, the threaded drive rod 34 is threadedly matched with the sliding part 321, and a worm part 351 is provided on the adjustment rod 35 to mesh with the worm wheel part 341 provided on the threaded drive rod 34.

[0030] Specifically, Figure 2 As shown, the adjusting rod 35 and the threaded driving rod 34 are both rotatably arranged on the rotating frame 31, and one end of the adjusting rod 35 extends out of the rotating frame 31 and faces away from the outer side of the other clamping claw 22, and the worm portion 351 of the adjusting rod 35 is meshed with the worm wheel portion 341 of the threaded driving rod 34, and the threaded driving rod 34 is threadedly matched with the sliding portion 321. The adjusting rod 35 can be manually rotated to drive the threaded driving rod 34 to rotate, and the threaded driving rod 34 rotates so that the mounting seat 32 is relative to the rotating frame. 31 slides relative to each other to adjust the distance between the flexible locking strip 33 and the clamping claw 22, which is convenient for actual use and position adjustment of the flexible locking strip 33; secondly, since the worm portion 351 and the worm wheel portion 341 are engaged with each other to drive the threaded driving rod 34, when the adjustment rod 35 is not subjected to force, the worm portion 351 and the worm wheel portion 341 can form a self-locking function to avoid the problem of accidental sliding of the mounting seat 32 relative to the rotating frame 31, thereby ensuring the stable locking and limiting of the cylindrical workpiece by the flexible locking strip 33.

[0031] As an embodiment further provided by the present invention, a first chamber 332 and a second chamber 333 are defined in the flexible locking strip 33 , and the first chamber 332 and the second chamber 333 are connected to each other via a connecting hole defined in the flexible locking strip 33 .

[0032] Specifically, Figure 4 As shown, the flexible locking strip 33 is provided with a first chamber 332 and a second chamber 333, and the first chamber 332 and the second chamber 333 are connected to each other through a connecting hole. The first chamber 332 and the second chamber 333 are provided inside the flexible locking strip 33 to increase the deformation ability of the flexible locking strip 33 when it contacts the cylindrical workpiece, increase the deformation contact area between the flexible locking strip 33 and the cylindrical workpiece, and further improve the locking and limiting stability of the flexible locking strip 33 on the cylindrical workpiece.

[0033] As an embodiment further provided by the present invention, a contact hole 331 connected to the first chamber 332 is opened in the middle of the flexible locking strip 33, and the rotating frame 31 is driven to rotate so that the contact hole 331 approaches and contacts the circumference of the cylindrical workpiece, and the flexible locking strip 33 is pressurized so that the connecting hole is deformed to separate the first chamber 332 and the second chamber 333, and a negative pressure is formed in the first chamber 332.

[0034] Specifically, Figure 3As shown, a plurality of contact holes 331 are located in the middle of the flexible locking strip 33 and are connected to the first chamber 332. When the rotating frame 31 rotates to make the mounting seat 32 and the flexible locking strip 33 close to the upper end of the cylindrical workpiece, the middle of the flexible locking strip 33 is close to and contacts the circumference of the cylindrical workpiece, so that the opening of the contact hole 331 contacts the circumference of the cylindrical workpiece, and the middle of the flexible locking strip 33 is deformed and squeezed, so that the gas in the first chamber 332 is squeezed into the second chamber 333 through the connecting hole, and then as the flexible locking strip 33 continues to contact and deform, the gas in the first chamber 332 is squeezed into the second chamber 333. , the connecting hole is also deformed and bent and blocked. At this time, the first chamber 332 and the second chamber 333 are separated by the connecting hole, and the contact hole 331 connected to the first chamber 332 contacts the circumferential surface of the cylindrical workpiece and is blocked and adsorbed. At this time, if the cylindrical workpiece has an axial sliding tendency, the cylindrical workpiece will pull the contact hole 331 to generate negative pressure in the first chamber 332. The existence of the negative pressure in the first chamber 332 further forms an axial pulling force on the cylindrical workpiece through the contact hole 331, thereby further avoiding the problem of the cylindrical workpiece falling off.

[0035] Furthermore, a V-shaped concave clamping groove 221 is provided on the inner side surface of the clamping claw 22. The existence of the clamping groove 221 can further improve the circumferential clamping stability of the cylindrical workpiece. Secondly, the clamping groove 221 is aligned with the contact hole 331 in the middle of the flexible locking strip 33. When the clamping claws 22 approach each other to clamp the workpiece, the cylindrical workpiece is automatically centered under the influence of the clamping groove 221 so that the axis of the cylindrical workpiece is aligned with the middle of the flexible locking strip 33, thereby further improving the stability of the flexible locking strip 33 for locking and limiting the cylindrical workpiece.

[0036] As a further embodiment provided by the present invention, flexible contact members 36 are provided in a symmetrical linear array on the first side surface of the mounting seat 32 .

[0037] Specifically, Figure 2 As shown, the side of the mounting seat 32 facing the other clamping claw 22 is the first side, on which a flexible contact piece 36 is provided. If it is necessary to clamp a cylindrical workpiece with a larger diameter and a length greater than the flexible locking strip 33, the rotating frame 31 is flipped to allow the flexible contact piece 36 to rotate and contact the upper end circumference of the cylindrical workpiece to achieve locking and limiting, thereby increasing the applicability of the device.

[0038] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
