Description

Technical Field

[0001] The utility model relates to a multi-point positioning type power crossbeam, belonging to the technical field of textile machinery equipment. Background Art

[0002] In the FA507 series of spinning frames, mainly produced by the Second Textile Machinery Group in China, the center line of the track installed on the edge of the wall panel cannot be kept vertically aligned with the spindles on the reinforcing bar due to the excessive protrusion of the center wall panel. After the crossbeam in the collection system grabs the bobbin on the spindle, it cannot be inserted into the track in the same straight line. This is because the position of the track deviates from the center line of the spindle. Therefore, in the application of existing spinning frames, the position of the crossbeam needs to be adjusted, affecting work efficiency. Utility Model Content

[0017] The specific implementation of the present invention will be further described in detail below with reference to the accompanying drawings.

[0018] The utility model designs a multi-point positioning power beam, which is used to constitute the beam in the gathering system of the spinning frame. In actual application, the specific design includes a beam 1, and power devices corresponding to the preset local sections of the beam 1. The power devices are on the same side of the beam 1 and are respectively arranged on the side of the local section corresponding to the beam 1. The power devices work separately to jointly push the beam 1 back and forth in a direction perpendicular to the straight line on which it is located, thereby realizing the working movement of the beam 1.

[0019] Regarding the practical application of each of the above power devices, the structures of the power devices are designed to be the same as each other, such as Figure 1 and Figure 2As shown, each power device is specifically designed to include an electric telescopic motor, a straight rod 2, a robot herringbone arm 3, and a base plate 4. In the structure of the power device, one edge of the base plate 4 is fixedly connected to the side position of the beam 1 set by the power device, and the plane where the base plate 4 is located is parallel to the working moving track surface of the beam 1. The robot herringbone arm 3 includes a first arm 31 and a second arm 32. One end of the second arm 32 is movably connected to a specified position on the rod body of the first arm 31. The first arm 31 and the second arm 32 are in a coplanar posture with each other. The robot zigzag arm 3 is positioned above the upper surface of the substrate 4 with its surface parallel to the surface of the substrate 4. The other end of the second arm 32 in the robot zigzag arm 3 is movably connected to the upper surface of the substrate 4. The second arm 32 rotates relative to the end in the plane where the robot zigzag arm 3 is located. The end of the first arm 31 in the robot zigzag arm 3 corresponding to the second arm 32 facing away from the crossbeam 1 is connected to the frame structure of the spinning frame except the crossbeam 1. The end of the first arm 31 and the frame structure are fixed relative to each other, and the first arm The rod 31 rotates relative to the end in the plane where the robot arm 3 is located. The electric telescopic motor is arranged on one side of the base plate 4 at the side position of the beam 1 provided by the power device, and the driving end of the electric telescopic motor points to the side of the base plate 4. The driving end of the electric telescopic motor is connected to one end of the straight rod 2. The straight line where the straight rod 2 is located is parallel to the straight line where the beam 1 is located. The electric telescopic motor drives the straight rod 2 to move back and forth along the straight line where it is located. The other end of the first arm 31 in the robot arm 3 is defined as the active end of the robot arm 3. The movable end of the robot herringbone arm 3 is movably connected to the specified position of the rod body of the straight rod 2, and the first arm 31 rotates at an angle relative to the straight rod 2 at the movable end position. Based on the operation of the electric telescopic motor, the movable end of the robot herringbone arm 3 is driven to move back and forth along the straight line direction of the straight rod 2 via the straight rod 2. The end of the second arm 32 in the robot herringbone arm 3 connected to the base plate 4 drives the beam 1 to move back and forth relative to the frame structure of the spinning frame except the beam 1, and along the straight line perpendicular to the beam 1, thereby realizing the working movement of the beam 1.

[0020] In actual application, in order to better keep the straight rod 2 moving along its straight line direction under the control of the electric telescopic motor, as shown in FIG. Figure 1 and Figure 2As shown, further design is carried out for each power device, and each power device also includes at least one vertical plate 5, each vertical plate 5 is fixedly arranged on the upper surface of the base plate 4 in a posture perpendicular to the upper surface of the corresponding base plate 4 and along the straight line where the straight rod 2 is located, and the straight rod 2 passes through the surface of each vertical plate 5 in turn, and the straight rod 2 moves relative to the through holes on the surface of each vertical plate 5 it passes through. In this way, based on the fixed connection between the base plate 4 and the beam 1, and the fixed connection between each vertical plate 5 and the base plate 4, the position of each vertical plate 5 and the beam 1 is relatively fixed, and then through the design of multiple vertical plates 5, multiple points on the moving path of the straight rod 2 are limited to keep the straight rod 2 moving along the straight line where it is located, that is, the movement is also parallel to the straight line where the beam 1 is located, thereby ensuring the stability of the designed power device in actual application.

[0021] The above-mentioned vertical plate 5 design is continued to improve the stability of the movement of the crossbeam 1, and further for each power device, such as Figure 1 As shown, the design also includes a slide bar 9 and a slider 10. The slide bar 9 is located below the lower surface of the corresponding substrate 4, and the straight line direction of the slide bar 9 is parallel to the moving direction of the beam 1. The slider 10 is provided with a through hole running through both sides thereof, and the inner diameter is adapted to the outer diameter of the slide bar 9. The slider 10 is arranged on the lower surface of the corresponding substrate 4 in a manner that its through hole is movably sleeved on the slide bar 9. The substrate 4 moves based on the back and forth movement of the slider 10 connected thereto along the slide bar 9. In this way, the moving direction of the slider 10 thereon is limited by the design of the slide bar 9 with a fixed position and angle, thereby ensuring the moving direction of the substrate 4 fixedly connected to the slider 10 and the beam 1, thereby further improving the stability of the movement of the substrate 4 and the beam 1, and further ensuring the stability of the designed power device in actual application.

[0022] Since in actual application, the crossbeam 1 moves with the movement of the base plate 4 in each power device, and the base plate 4 is fixedly connected to the side of the crossbeam 1 in a posture parallel to the working moving track surface of the crossbeam 1, it is easy to be blocked by other structures during the movement of the base plate 4, that is, the movement displacement of the crossbeam 1 is restricted. Therefore, in actual application, the base plate 4 and the vertical plate 6 arranged thereon are analyzed and further structurally improved, such as Figure 1 and Figure 2As shown, based on the moving direction of the beam 1 as the projection direction, if there is an overlapping area between the projection of the other end of the second arm 32 in the robot herringbone arm 3 and the spinning frame structure connected thereto along the projection direction and the projection of the base plate 4 along the projection direction, a first opening 6 is opened from the position corresponding to the overlapping area on the edge of the base plate 4 facing away from the beam 1, and along the straight line in the projection direction toward the inner direction of the surface of the base plate 4, that is, the first opening 6 is designed for the position on the base plate 4 blocked by the other end of the second arm 32 and the structure connected thereto. During the movement of the base plate 4, the two sides of the first opening 6 move to the two sides of the blocking structure, thereby clearing the blocking structure from blocking the movement of the base plate 4, ensuring the maximum displacement of the base plate 1, and thus achieving the maximum working displacement of the beam 1.

[0023] Similarly, if there is an overlapping area between the projection of the robot herringbone arm 3 along the projection direction and the projection of each vertical plate 5 along the projection direction, a second opening is opened for each vertical plate 5 with overlap, from the position corresponding to the overlapping area on the edge of the vertical plate 5 facing away from the beam 1, and along the inner direction of the surface of the vertical plate 5 where the working movement track surface of the beam 1 is located. Similarly, through this second opening, the robot herringbone arm 3 is prevented from blocking the vertical plates 5 at the corresponding positions, thereby ensuring the maximum displacement of the base plate 1 and thereby achieving the maximum working displacement of the beam 1.

[0024] In the above design, an electric telescopic motor is used to provide thrust for the connected straight rod 2, and the design requires precise control of each movement displacement of the straight rod 2. In this regard, in actual application, the electric telescopic motor here can be a servo motor with a telescopic function; or according to the characteristics of the complete extension and complete retraction of the electric cylinder 7, a design of at least two electric cylinders 7 can be adopted, such as Figure 1 and Figure 2 As shown, the specific design is based on that the driving end of one electric cylinder 7 is connected to the tail of another electric cylinder 7 facing away from its driving end, and the straight lines where the driving ends of each electric cylinder 7 move are parallel to each other, so that each electric cylinder 7 is connected in series in sequence, and the driving end that does not participate in the connection between the electric cylinders 7 in the series structure constitutes the driving end of the electric telescopic motor, and based on the electric cylinder 7 to which the driving end belongs constitutes the first electric cylinder 7 in the series structure, the last electric cylinder 7 in the series structure is set at the setting position of the electric telescopic motor on the side of the beam 1, and the remaining electric cylinders 7 are not fixed to the beam 1; with such a design, based on the maximum pushing distance when all the electric cylinders 7 are fully pushed out and the minimum pushing distance when all the electric cylinders 7 are fully retracted, each electric cylinder 7 realizes a state combination of fully pushed out or fully retracted, and realizes the minimum pushing distance, maximum pushing distance, and multiple pushing distances between the two for the straight rod 2, thereby achieving the specific design purpose of the pushing distance of the straight rod 2.

[0025] In actual application of the above design, each power device is also designed to include a displacement sensor 8. The displacement sensor 8 is arranged on the local section of the corresponding straight rod 2 that has not passed through the mechanical herringbone arm 3 and each vertical plate 5. The displacement sensor 8 detects the displacement of the local section of the beam 1 corresponding to the power device. In specific practical applications, a control module is also designed to be added. Each electronically controlled cylinder 7 in each power device is connected to the control module respectively. The control module controls each electronically controlled cylinder 7 in each power device respectively, that is, the beam 1 is designed to be loaded with multi-point power to achieve multi-point positioning of the beam 1 during application.

[0026] The multi-point positioning power beam designed above is applied in practice, targeting each power device, such as Figure 2 As shown, the electric telescopic motor controls the straight rod 2 to be pushed to the left along its straight line. As the straight rod 2 moves, the end of the first arm 31 connected to the straight rod 2 is also pushed to the left along its straight line. Since the other end of the first arm 31 is connected to the frame structure of the spinning frame except the crossbeam 1, that is, the position of the first arm 31 is relatively fixed to the frame structure of the spinning frame, the angle between the second arm 32 and the first arm 31 corresponding to the structure connected to the frame structure of the spinning frame gradually becomes smaller, and the other end of the second arm 32 drives the base plate 4 connected to it to move along the straight line. Figure 2 Move downward, driving beam 1 along Figure 2 The cross beam 1 moves downward in the middle, that is, the power device drives the cross beam 1 to move.

[0027] The multi-point positioning power beam designed in the utility model is designed to design each power device to drive the beam 1 in the spinning frame gathering system at multiple points, so as to realize the multi-point positioning of the beam 1 during operation, and specifically for each power device, the beam 1 is connected with the base plate 4, and the electric-controlled telescopic motor is used to provide the straight rod 2 with a thrust in the direction parallel to the beam 1, and the mechanical herringbone arm 3 structure is introduced to complete the conversion of the thrust to the direction perpendicular to the beam 1, and then vertical forces are obtained at multiple points on the beam 1, which jointly push the beam 1 to work and move; the structure of each power device effectively overcomes the narrow space where the beam 1 is located, and the structure cleverly realizes the conversion of force in different directions, ensures the force required by the beam in the working movement direction, and improves the working efficiency of the beam 1.

[0028] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in this field without departing from the purpose of the present invention.
