[0049] The utility model provides a first aspect of a clamper used at the end of a handling device, which is used to clamp a tubular yarn ball and cooperate with other mechanisms of the handling device to clamp, transport and install the tubular yarn ball under the drive of a motor.

[0050] Now, exemplary embodiments according to the present invention will be described in more detail with reference to the accompanying drawings.

[0051] like Figure 1 and Figure 2As shown, the utility model provides a clamp 100 for clamping a yarn ball under the drive of a motor. The clamp 100 includes a base 10, a clamping plate 20 and a transmission assembly 30. The base 10 is provided with a slide groove 11 perpendicular to the axial direction D1 of the base 10. The two clamping plates 20 are arranged relatively along the slide groove 11, and can move closer to each other and away from each other along the slide groove 11. The transmission assembly 30 includes a driving shaft 31, a screw rod 32, a driven gear and a slider 34. The driving shaft 31 is arranged along the axial direction D1 of the base 10, and one end of the driving shaft 31 has a driving gear. The screw rod 32 is arranged in the slide groove 11, and the driven gear is arranged on the screw rod 32 and meshes with the driving gear. The slider 34 has an internal thread and is screwed to the screw rod 32. The slider 34 is fixedly connected to the clamping plate 20 to drive the clamping plate 20 to move along the slide groove 11 when the driving shaft 31 rotates. It can be understood that the driving shaft 31 rotates around its own axis under the drive of the motor, and the meshing of the driving gear and the driven gear drives the screw rod 32 in the slide slot 11 to rotate around its own axis. The rotation of the screw rod 32 causes the slider 34 screwed thereto to slide along the slide slot 11 (i.e., along the screw rod 32), so that the clamping plate 20 fixed to the slider 34 moves along the slide slot 11. The two clamping plates 20 are respectively arranged on both sides of the driven gear along the slide slot 11, and move closer to and away from each other under the action of the transmission assembly 30.

[0052] Specifically, the yarn ball is cylindrical and has an inner surface and an outer surface. If the initial distance between the two clamping plates 20 is set to be greater than the outer diameter of the yarn ball, the two clamping plates 20 move closer to each other along the slide groove 11, and can clamp the outer surface of the yarn ball, thereby clamping the yarn ball and cooperating with other mechanisms of the handling device to move the yarn ball. Alternatively, if the initial distance between the two clamping plates 20 is set to be less than the inner diameter of the yarn ball, the two clamping plates 20 move away from each other along the slide groove 11, and can press against the inner surface of the yarn ball, thereby clamping the yarn ball and cooperating with other mechanisms of the handling device to move the yarn ball.

[0053] Optionally, the base 10 may be provided with a slide groove 11, in which a screw rod 32 is provided, and the driven gear is located in the middle of the screw rod 32. Both ends of the screw rod 32 are provided with threads, which are respectively screwed to the slider 34.

[0054] Preferably, if Figure 1As shown, the base 10 has two vertically arranged slide grooves 11, and the clamp 100 includes two pairs of clamping plates 20, and the two pairs of clamping plates 20 are respectively arranged in the two slide grooves 11, that is, a pair of clamping plates 20 arranged opposite to each other is arranged in each slide groove 11. Specifically, a slider 34 and a screw rod 32 are correspondingly arranged for each clamping plate 20. The four screw rods 32 are respectively provided with bevel gears 33, and the bevel gears 33 of adjacent screw rods 32 are meshed with each other, so that the four screw rods 32 rotate synchronously, thereby driving the two pairs of clamping plates 20 to move close to each other along the slide groove 11 at the same time, and clamp the outer surface of the yarn ball together, or the two pairs of clamping plates 20 move away from each other along the slide groove 11 at the same time, and press against the inner surface of the yarn ball together.

[0055] In one embodiment, the driven gear is one of the four bevel gears 33, that is, the driving gear meshes with one of the bevel gears 33, for example, by setting the position of the driving gear, it is biased towards one of the bevel gears 33, rather than being located at the center of the four bevel gears 33. Under the action of the driving gear, the driven gear drives the other three bevel gears 33 to rotate, thereby causing the screw rod 32 to rotate at the same time, that is, the four clamping plates 20 move at the same time. In another embodiment, the size of the bevel gear 33 can be set so that the driving gear meshes with one of the bevel gears 33 or with a pair of opposite bevel gears 33.

[0056] In one embodiment, Figure 2 As shown, one of the four screw rods 32 is provided with a second gear 35, and the driven gear is the second gear 35, and the diameter of the second gear 35 is greater than the diameter of the bevel gear 33 to mesh with the driving gear 311. Optionally, when the driving gear 311 is configured to mesh with the second gear 35, its diameter size is greater than the diameter size when it is configured to mesh with the bevel gear 33.

[0057] Preferably, along the circumferential direction D2 of the base 10 , surfaces of the four screw rods 32 are alternately provided with positive threads and negative threads, so that the four clamping plates 20 can be synchronously moved toward and away from each other.

[0058] Preferably, the base 10 is provided with a first through hole 12 arranged along the axial direction D1 of the base 10, the first through hole 12 is at least partially located in the slide groove 11, a fixing ring 13 is arranged in the first through hole 12, the bevel gear 33 is located in the fixing ring 13, the fixing ring 13 has a second through hole along the slide groove 11, the screw rod 32 passes through the second through hole and is fixedly connected to the bevel gear 33, and the fixing ring 13 can be used to support the screw rod 32. The first through hole 12 is arranged at the position where the two slide grooves 11 intersect.

[0059] Preferably, the base 10 is cylindrical, and the slide groove 11 is arranged along the radial direction of the base 10 .

[0060] Optionally, the clamping plate 20 is fixed to the slider 34 via a mounting seat 21 .

[0061] Preferably, the clamping plate 20 is an arc-shaped plate, and the arc surfaces of the two clamping plates 20 in the same slide groove 11 are arranged opposite to each other, so that they can be better adapted to the shape of the cylindrical object to clamp the outer surface of the cylindrical object or press against the inner surface of the cylindrical object.

[0062] Preferably, wear-resistant shock-absorbing pads 22 are provided on the inner and / or outer sides of the clamping plate 20 to avoid damaging the surface of the clamped object such as the yarn ball and to avoid surface wear of the clamping plate 20. At the same time, the wear-resistant shock-absorbing pads 22 can prevent slipping, making the clamping plate 20 clamped more stably.

[0063] The second aspect of the utility model provides a handling device, which includes the above-mentioned clamp 100. The handling device can clamp the cylindrical object through the clamp 100 and move the cylindrical object to a set position. For example, in the process of making fiber composite materials, the yarn ball is installed on the yarn frame, or the yarn ball on the yarn frame is removed and replaced, so as to realize automatic yarn loading, save manpower, and improve installation accuracy and efficiency.
