Detailed Description
The present invention is described in detail below with reference to the attached drawings. It is to be understood, however, that the drawings are provided solely for the purposes of promoting an understanding of the invention and that they are not to be construed as limiting the invention. In describing the present invention, it is to be understood that the terminology is used for the purpose of description only and is not intended to be interpreted as indicating or implying any relative importance.
The embodiment discloses a coil forming device, as shown in fig. 1, comprising a deflection part 1, a rotation part 2, a terminal execution part 3 and a control part (not shown in the figure); the deflection part 1 is connected with the rotating part 2 and is used for driving the rotating part 2 to rotate by a preset angle; the rotating part 2 is provided with a hollow channel for the base body 4 of the coil to be wound to pass through; a gap is arranged between the inner wall of the hollow channel and the outer wall of the base body 4; the end execution part 3 is connected to the side wall of the rotating part 2, moves along the circumferential direction of the rotating part along the circumference of the hollow channel and is used for forming a coil on the base body 4; the control part is connected with the deflection part 1, the rotating part 2 and the tail end execution part 3 and is used for controlling the motion trail of the tail end execution part 3. According to the device, the deflection part 1, the rotating part 2 and the tail end execution part 3 are controlled to be linked through the control part, so that the motion track of the tail end execution part on the base body 4 is controlled, the coil can be wound into any required shape, the production efficiency and the qualification rate of the coil with a complex structure are improved, and the labor cost is reduced. In addition, various end executing parts 3 can be installed on the rotating part 2 according to specific operation requirements, and the end executing parts 3 can be installed to realize different functional modules, such as a milling cutter, a superconducting tape spool, a 3D printing head, a glass fiber tape winding head, a positioning tip and the like, so that the coil forming device in the embodiment has more comprehensive and diversified functions.
In the present embodiment, the base 4 may have any shape, but since the apparatus for winding the coil is generally tubular, the base 4 is preferably a straight tube or a bent tube having a circular or elliptical cross section. The device in the embodiment is particularly suitable for the bent pipe with the bending angle of 60-90 degrees, namely a large-angle bent pipe. Although the device in the prior art has a complex structure and needs to be provided with the up-and-down moving slide rail and the slide block independently, the device can basically meet the requirement of winding a coil on a straight pipe or a bent pipe with a small bending angle. For a large-angle bent pipe, due to the particularity of the winding shape of the coil, the device in the prior art cannot automatically and accurately complete the winding. The device of the embodiment accurately sets the motion track of the end effector 3 by controlling the deflection unit 1, the rotating unit 2 and the end effector to be linked through the control unit. FIGS. 2-4 are schematic diagrams of winding paths of a diode-bent oblique-solenoid type coil, respectively; the winding path schematic diagram of the four-pole and six-pole straight tube inclined solenoid type coil; a schematic diagram of a quadrupole discrete Cos (n θ) -type coil winding path. As shown in fig. 2 to 4, the winding path of the oblique solenoid coil of either the straight tube or the bent tube or the discrete Cos (n θ) type coil is very complicated, and the coil cannot be wound into such a complicated shape by only the winding device moving linearly in the three directions of XYZ, but with the device in this embodiment, the controller can control each component in real time according to the pattern by inputting the corresponding pattern into the controller, so that the end executing unit 3 times completes the winding of the coil with the required spatial path shape.
The end executing part 3 moves along the circumferential direction of the hollow channel of the rotating part 2. The central axis of the base body 4 is a connecting line of the circle centers of all the cross sections of the base body. When the base body 4 is a straight pipe, the central axis is a straight line, and the deflection angle of the rotating part 2 does not need to be changed in the whole operation process; however, when the base 4 is a bent pipe, the tangent line of each point of the central axis changes in real time, so that the controller is required to adjust the posture of the rotating part 2 by adjusting the deflection angle of the deflection part 1, and the cross section of the hollow channel should be perpendicular to the tangent line of the central axis at the intersection point of the base 4 and the central axis. Wherein, the deflection part 1 is a circular ring rotator, an object carrying platform 21 is arranged on the deflection part 1, and the control part can control the deflection part 1 to realize the angle adjustment of +/-180 degrees of the object carrying platform 21. The loading platform 21 is provided with a fixing member 22, and the fixing member 22 is used for being fixedly connected with the rotating part 2 and supporting the rotating part 2. For more stable fixation, the fixing members 22 are preferably two. The two stationary members support the rotary unit 2 from the left and right sides.
In order to make the end effector 3 act on the base body 4 better, the cross section of the hollow channel and the cross section of the base body are preferably set to be the same shape, if the base body 4 is a pipe with a circular cross section, the cross section of the central channel is also circular, and the center of the cross section of the base body 4 coincides with the center of the cross section of the central channel, that is, the cross section is set to be coaxial with the central channel. Wherein the cross-section is defined herein as the plane perpendicular to the axis of the length of the pipe.
In order to increase the adjustment dimension of the coil forming device and meet the requirement of the length direction of the pipe, the coil forming device further comprises a plane moving part 5, the plane moving part 5 is arranged below the deflection part 1 and fixedly connected with the deflection part 1, and the plane moving part 5 is used for adjusting the position of the deflection part 1 in a plane. The plane moving section 5 further includes a horizontal moving section that moves in the horizontal direction, and a vertical moving section that moves in a direction perpendicular to the horizontal direction. The horizontal moving part comprises a first slide rail 51 and a first slide block 52 arranged on the first slide rail 51; the vertical moving part includes a second slide rail 53 and a second slider 54 disposed on the second slide rail 53; the first slider 52 is provided with a second slide rail 53, the installation direction of the second slide rail 53 is perpendicular to the installation direction of the first slide rail 51, and the second slider 54 is provided with a deflection part 1.
In order to allow the base 4 to pass through the hollow passage without contacting the inner wall of the hollow passage, the coil forming apparatus further includes a base support 6 for supporting the base 4. Preferably, the base support portions 6 are provided in two numbers, respectively, on both sides of the rotating portion 1 to prevent the base 4 from falling.
The above embodiments are only used for illustrating the present invention, and the structure, connection mode, manufacturing process, etc. of the components may be changed, and all equivalent changes and modifications performed on the basis of the technical solution of the present invention should not be excluded from the protection scope of the present invention.
