Description

Technical Field

[0001] This utility model belongs to the field of magnetic field measuring instrument manufacturing equipment, and particularly relates to a tooling for winding a spherical sensor. Background Technology

[0002] The probes of measuring instruments used to measure magnetic fields are generally spherical, plate-shaped, or cylindrical. Spherical probes have coils inside the sensor along the meridian and parallel directions, enabling them to sense magnetic fields in three-dimensional space. For example, the vector magnetic field measuring device based on a scalar magnetic probe disclosed in the existing patent CN202222186046.X includes a set of orthogonal spherical coils set on a two-dimensional adjustment bracket, as well as a scalar magnetic probe, a signal processing unit, and a data acquisition unit. Another example is CN217718062U, which discloses a three-dimensional magnetic field measuring head and measuring device based on triaxial probe coil sensing, including a spherical probe housing and three probe coils. The probe housing surface has three annular grooves, and a probe coil is wound in each annular groove. The planes in which the three probe coils are located are arranged perpendicularly to each other.

[0003] Traditional coil winding is done manually, but many workshops now use motorized equipment for fast and accurate coil winding to improve production efficiency. However, because the winding fixtures in the workshops are general-purpose, there is a mismatch between the positioning nodes of the spindle and the sphere when the coil is offset on the sphere, which affects the coil winding operation.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Examples, such as Figures 1-5 As shown, the spherical sensor winding fixture provided by this utility model includes a first fixture 1 and a second fixture 2. The first fixture 1 includes a first shaft head 11, one end of which is provided with a T-flange 12. The end of the T-flange 12 is provided with a positioning clamp 13, which includes a retaining shaft 131 connected to the T-flange 12. The end of the retaining shaft 131 is provided with a first clamping plate 132, and the first clamping plate 132 and the retaining shaft 131 are provided with an integrally connected U-shaped positioning groove 133. Specifically, the first shaft head 11 can cooperate with the clamping chuck of the spindle machine tool, the first clamping plate 132 cooperates with the root of the central shaft of the spherical sensor, and the U-shaped positioning groove 133 cooperates with the central shaft and keyway of the spherical sensor, thereby realizing the positioning and clamping of the central shaft. By installing the first fixture 1 in pairs on the spindle chuck and tailstock chuck of the machine tool, the positioning of the spherical sensor can be completed. With the help of the winding equipment, the winding of the positive coil can be completed.

[0021] Furthermore, the second tooling 2 includes a second shaft head 21. One end of the second shaft head 21 is provided with a limiting plate 22. The end of the limiting plate 22 is provided with spacer blocks 23 distributed near its bottom. The end of the spacer blocks 23 is provided with a second clamping plate 24. The end of the second clamping plate 24 is provided with a clamping curved surface 25. The upper half of the clamping curved surface 25 is provided with a positioning hole 26. The clamping curved surface 25 is provided with a groove 27 located obliquely below the positioning hole 26. A positioning shaft 28 is provided in the groove 27. Specifically, the second shaft head 21 can cooperate with the clamping jaw disk of the spindle machine tool. The limiting plate 22 abuts against the end face of the jaw disk. The clamping curved surface 25 of the second clamping plate 24 cooperates with the eccentric position of the spherical sensor. The positioning shaft 28 is in an eccentric position and can cooperate with the eccentric eye of the spherical sensor. By installing the second tooling 2 in pairs on the spindle chuck and tailstock chuck of the machine tool, the eccentric positioning of the spherical sensor can be completed. With the help of the winding equipment, the winding of the offset position coil can be completed.

[0022] To improve the uniformity of the clamping force of the second tooling 2, and considering the position design of the positioning shaft 28, this invention sets the spacer block 23 at an eccentric position relative to the second shaft head 21, with the force-bearing surface of the spacer block 23 facing the area where the positioning shaft 28 is located. Simultaneously, the spacer block 23 has an isosceles triangular structure, which provides sufficient space for the positioning hole 26 and the positioning shaft 28, facilitating the installation of other positioning components adapted to the spherical sensor.

[0023] To improve the positioning effect of the second tooling 2 on the spherical sensor, this invention provides a C-groove 29 on one side of the spacer block 23. A threaded hole corresponding to and communicating with the C-groove 29 is provided in the recess 27. The positioning shaft 28 is disposed in the threaded hole, and a core hole 210 is provided at one end of the positioning shaft 28. The core hole 210 is fitted with a mandrel 211 located at the end of the C-groove 29. A tension spring 212 is provided between the positioning shaft 28 and the C-groove 29. By adjusting the engagement position of the positioning shaft 28 in the threaded hole, the working length of the positioning shaft 28 can be adjusted. Furthermore, the mandrel 211 ensures the coaxiality of the positioning shaft 28 during positioning, reducing the probability of radial runout. The tension spring 212 provides pre-tension, which helps to improve the engagement progress between the positioning shaft 28 and the threaded hole, thereby ensuring the positioning performance of the positioning shaft 28.

[0024] To improve the fit between the first tooling 1 and the central axis of the spherical sensor, the present invention provides a pressure groove 134 on the surface of the first clamping plate 132, which fits with the shoulder at the root of the central axis. At the same time, the first clamping plate 132 is provided with multiple through holes 135 near its edge, in which screws and bolts can be installed to increase the positioning nodes of the first tooling 1 on the spherical sensor and improve the assembly quality of the first tooling 1 and the spherical sensor.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
