Description

Technical Field

[0001] The utility model relates to the technical field of coil production, in particular to a coil axial width pressing device. Background Art

[0002] When winding the second turn of a double-layer spiral coil, if the axial and radial dimensions are not effectively controlled, it is easy to cause the wire to tilt, affecting the radial and axial dimensions, causing the coil's external dimensions to be out of tolerance, and then causing the outer coil to not fit properly when the coil is fitted as a whole.

[0003] Based on this, CN 117457382 A discloses a coil axial and radial clamping device, which comprises a first column and a second column slidably mounted on a track. A power mechanism drives the first and second columns to move along the track, a first clamping assembly is mounted on top of the first column, and a second clamping assembly with a second clamping force is mounted on top of the second column. A controller controls the power mechanism to drive the first and second columns to coordinate with a horizontal winding machine to wind the coil. During coil winding, the first and second clamping forces provided by the first and second clamping assemblies control the axial and radial dimensions of the coil, ensuring the coil's overall dimensions. However, the following problem still exists: the first and second columns are controlled separately by power mechanisms, and their separate structures hinder collaborative operation. Utility Model Content

[0004] The purpose of the utility model is to provide a coil axial and width pressing device with a reasonable structure and reliable use to solve the above problems, which is more convenient for controlling the axial and width dimensions, reduces the difficulty of operating the power mechanism, and has low use cost.

[0005] The technical solution of the utility model is:

[0006] A coil shaft radial clamping device comprises a base, a radial clamping assembly and an axial clamping assembly, and its technical highlights are: an X-direction horizontal screw is supported above the base, one end of the X-direction horizontal screw is connected to a drive motor, a wire sleeve is provided on the X-direction horizontal screw and the outer side of the wire sleeve is connected to a movable frame, a horizontal support plate is provided on the top of the movable frame, an X-direction slide is provided above the horizontal support plate, a slider is provided on the X-direction slide, an X-direction spring is provided between one side of the slider and the fixed block at the end of the horizontal support plate, and the other side of the slider is connected to an X-direction pull rod, the radial clamping assembly comprises a cantilever connected to the other end of the X-direction pull rod, a Z-direction spring is fixed on the lower surface of the cantilever end, a wheel frame provided at the lower end of the Z-direction spring, and a Z-direction clamping roller provided on the wheel frame, and the axial clamping assembly comprises a Z-direction extension arm fixed on the front side arm of the wheel frame, and an X-direction clamping column provided at the lower end of the Z-direction extension arm.

[0007] The above-mentioned coil axis radial pressing device has a horizontal rotating shaft for winding the coil fixed on the base, the movable frame is provided with an avoidance opening corresponding to the horizontal rotating shaft, and the horizontal support plate is located above the horizontal rotating shaft in the vertical direction.

[0008] The above-mentioned coil axial radial pressing device has an X-direction sliding groove corresponding to the wire sleeve on the upper surface of the base.

[0009] In the above-mentioned coil axial width pressing device, the axle of the Z-direction pressing roller is parallel to the horizontal rotating axis used for winding the coil.

[0010] The beneficial effects of the utility model are:

[0011] When winding the second coil, the Z-direction clamping roller is used to perform widthwise or radial clamping and limiting on the second coil, and the X-direction clamping column is used to perform axial clamping and limiting on the second coil. The same X-direction horizontal lead screw and the corresponding wire sleeve are used to realize working feed, which makes the control of axial and widthwise dimensions more coordinated and convenient, reduces the difficulty of operating the power mechanism, and has low cost of use.
