Detailed Description
The structure of the present invention will be further described by way of examples with reference to the accompanying drawings. It is to be understood that this embodiment is illustrative and not restrictive.
A high-precision winding tool for a flat enameled wire winding of a sensor is disclosed, please refer to FIGS. 1-5, and the invention point is as follows: the winding tool comprises a winding tool body formed by connecting a die rod 1, a mandrel 7 and a cylindrical module 3 and a fixed-width size sheet 6 for determining the width of a winding groove in the winding tool body.
The die rod, the mandrel, the cylindrical module and the fixed-width size sheet are all manufactured by adopting a precision machining method, the size and form and position tolerance of each part are controlled within 0.005mm, so that high precision is achieved after assembly, and a high-precision winding is obtained after winding. The parallelism requirement of the outer end face of the cylindrical die head of the die rod and the inner end face of the cylindrical module is high, after the parts are assembled, the parallelism of the two end faces is controlled within 0.04mm, and the perpendicularity of the inner circular face of the winding groove and the two end faces is controlled within 0.02 mm.
The specific structure of each part and the connection relationship of each part are as follows:
the die rod is an installation base part of other components of the winding tool and is a rod body structure with a cylindrical die head 1.1 arranged at one end. The center of the die rod is provided with a shaft hole, the outer side part of the cylindrical die head on the die rod is provided with a radial jackscrew hole, and the end surface of the cylindrical die head is provided with a lead groove 1.2 at the position tangent to the shaft hole. And one end of the die rod, which is far away from the cylindrical die head, is a connecting end which is in plug-in fit with a corresponding winding interface of the winding machine. Two planes which are symmetrically arranged are processed on the mold rod (excluding the cylindrical die head part), and a radial jackscrew hole is processed on the plane on one side of the mold rod, so that the mold rod can be conveniently matched with a winding interface of a winding machine.
The mandrel is used for positioning the initial position of the inner ring wound by the winding and is a cylindrical mandrel, the outer diameter of the mandrel is consistent with the set inner diameter of the winding, and a central threaded hole is formed in one end of the mandrel.
The cylindrical module is matched with the cylindrical die head of the die rod and used for limiting the sizes of the two wound ends, the outer diameter of the cylindrical module is consistent with that of the cylindrical die head of the die rod and is larger than the set outer diameter of the winding, and a counter bore is arranged in the center of the cylindrical module;
the fixed-width size piece is used for determining the width of the winding slot, the thickness of the fixed-width size piece is 0.015-0.020mm larger than the width of the winding, a fixed-width socket 6.1 is arranged at one end of the fixed-width size piece, and the width of the fixed-width socket is consistent with the outer diameter of the mandrel
The cylindrical module and the mandrel are coaxially and fixedly connected through a screw A4 connected in the countersunk hole and the central threaded hole; the mandrel is inserted and matched with the shaft hole on the die rod in a mode that the end part of the mandrel is exposed, and the mandrel is fixedly connected with the die rod through a screw B2 arranged in the radial jackscrew hole; and a winding groove 5 is formed between the outer end surface of the cylindrical die head and the cylindrical module, and the width of the winding groove is consistent with the thickness of the fixed-width dimension piece.
Adopt this coiling frock to carry out the winding coiling and solved several aspects's problems:
1. the flat winding 100 of the sensor is formed by spirally winding a single-layer flat enameled wire, and the thickness of the flat winding is the width of the enameled wire. When winding, because the width of the flat enameled wire is larger (such as 0.5mm), the head end of the inner-layer winding is simply fixed, so that the parallel potential difference of two ends of the flat winding is caused, and the performance of the sensor is reduced. In order to solve the problem that two ends of a flat winding are not parallel due to the leading-out wire 101 at the head end, a groove, namely the leading-out groove, is processed on a winding tool, a flat enameled wire is smoothly laid in the leading-out groove before winding, and then the flat enameled wire is wound on a mandrel during winding. Because the flat enameled wire is smoothly laid in the lead slot, the head end of the enameled wire cannot influence the parallelism of the two ends of the flat winding.
2. The axial dimension of the flat winding has a relatively obvious influence on the measurement of the position performance of the sensor, so that the axial dimension of each flat winding is required to be consistent and close to the width of an enameled wire, and the performance of the sensor is ensured. In order to ensure good axial size consistency of the flat winding, a winding fixed-width size sheet is designed. And when the winding tool is assembled, the width of the winding slot is controlled by using the size sheet, so that the flat winding with the consistent axial size is obtained after winding. In order to ensure that the winding is smooth and the axial dimension of the winding meets the requirement, the thickness of the fixed-width dimension piece is generally 0.015-0.020mm larger than the width of the enameled wire.
3. The winding slots of the flat winding are designed to be detachable, so that the winding can be conveniently detached after winding. The tool is designed into a mandrel, a mold rod and a module, so that the tool is convenient to assemble, and the tool is disassembled after winding is completed, so that a flat winding can be obtained.
The method for winding the winding by adopting the high-precision winding tool for the flat enameled wire winding of the sensor comprises the following steps:
step 5, taking down the sheet with the fixed width, and forming a winding groove between the cylindrical die head and the cylindrical module of the die rod;
step 8, starting a winding machine, and winding a flat enameled wire on a mandrel;
step 9, after the winding of the flat winding is finished, blowing the flat enameled wire through a hot air gun to enable the thermal bonding layer to play a role, and shaping the winding;
and step 10, after the winding is shaped, detaching the screw A and the screw B on the tool, and taking out the flat winding.
Although the embodiments of the present invention and the accompanying drawings are disclosed for illustrative purposes, those skilled in the art will appreciate that: various substitutions, changes and modifications are possible without departing from the spirit of the invention and the scope of the appended claims, and therefore the scope of the invention is not limited to the disclosure of the embodiments and the accompanying drawings.
