Description

Technical Field

[0001] The invention relates to the technical field of motor production and processing equipment, in particular to an excitation coil heating and shaping device. Background Art

[0002] In the stator production process, it is an important process to heat the excitation coil (hereinafter referred to as "coil") with electricity to melt the colloid on the surface and then bond them together. Improving production efficiency and reducing labor intensity are also key points that must be controlled in factory operations.

[0003] At present, the method for motor manufacturers to heat the coil by electricity is relatively complicated. The coil needs to be removed from the equipment and the insulating paint on the wire head needs to be manually removed. The wire is then manually connected to a specific power supply circuit and then heated by electricity. The entire process is manually operated, which brings inconvenience to motor manufacturers.

[0006] The excitation coil heating and shaping device in the present invention is the first to use extrusion teeth.

BRIEF DESCRIPTION OF THE DRAWINGS

[0007] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0008] Figure 1It is a schematic diagram of the structure of the excitation coil heating and shaping device in the present invention. DETAILED DESCRIPTION

[0009] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0010] Reference Figure 1 The present invention provides an excitation coil heating and shaping device, which includes a first clamp block 100 and a second clamp block 200, and the first clamp block 100 and the second clamp block 200 are arranged opposite to each other. At least one clamping guide rod 300 is vertically fixedly installed on the side of the second clamp block 200 facing the first clamp block 100, and a through hole with a diameter equivalent to the diameter of the clamping guide rod 300 is opened on the first clamp block 100. After the end of the clamping guide rod 300 away from the second clamp block 200 passes through the through hole, a clamp baffle plate 310 is fixedly installed. The clamp baffle plate 310 is connected to a driving device to drive the clamp baffle plate 310 to move. The driving device can be a cylinder or a linear motor or other equipment.

[0011] The first clamping block 100 and the second clamping block 200 are respectively provided with extrusion blocks 400 on opposite sides, and the two extrusion blocks 400 are respectively provided with a plurality of extrusion teeth on opposite sides. In order to prevent the extrusion teeth from cutting the wire in the coil, the first clamping block 100 and the second clamping block 200 are provided with mounting grooves on opposite sides, and the two extrusion blocks 400 are respectively installed in the two mounting grooves, and the extrusion teeth on the extrusion blocks 400 slightly protrude from the opposite sides of the first clamping block 100 and the second clamping block 200, and the protrusion amount can be set to be very small, for example, 0.1 mm, so that the extrusion teeth will not be inserted too deep into the wire after being inserted into the wire, causing the wire to be cut.

[0012] In order to position the coil, a wire blocking rod 500 is provided between the first clamping block 100 and the second clamping block 200 , one end of the wire blocking rod 500 is vertically fixed on the side of the second clamping block 200 facing the first clamping block 100 , and the other end is inserted into a through hole opened on the side of the first clamping block 100 .

[0013] The extrusion teeth on the two extrusion blocks 400 are connected to the power supply. In this embodiment, the extrusion block 400 and the extrusion teeth are made of metal materials, and the extrusion teeth are integrally formed or welded on the extrusion block 400. The extrusion teeth can be connected to the power supply after the power line is connected to the extrusion block 400. It should be understood that insulation measures need to be taken between the extrusion block 400 and the first clamping block 100 and the second clamping block 200. Insulation layers can be laid between the extrusion block 400 and the first clamping block 400 and between the extrusion block 400 and the second clamping block 200, or the first clamping block 100 and the second clamping block 200 are both made of insulating materials.

[0014] In this embodiment, the extrusion teeth on the two extrusion blocks 400 are electrically connected to the positive and negative electrodes of the power supply respectively. When the coil is placed between the two extrusion blocks 400 and leans against the wire blocking rod 500, the driving device is started to move the second clamping block 200 toward the first clamping block 100. The extrusion teeth on the two extrusion blocks 400 clamp the coil in the middle and break the insulating layer on the surface of the wire. Finally, the extrusion teeth are electrically connected to the wire. After the wire is connected to the power supply, current is generated and heat is generated. The heat generated melts the colloid on the surface of the coil to make the coil a whole. After the heating is completed and the colloid is cooled, the coil is shaped.

[0015] In another embodiment, two shaping devices can be used to shape a wire at the same time. In this case, the number of extrusion blocks 400 in each shaping device can be one or two. If the number of extrusion blocks 400 is one, it can be installed on the first clamping block 100 or the second clamping block 200. If the number of extrusion blocks 400 is two, they are installed on the first clamping block 100 or the second clamping block 200 respectively. In this embodiment, the extrusion teeth in the two shaping devices are electrically connected to the positive and negative electrodes of the power supply respectively. At this time, the driving devices in the two shaping devices move synchronously, breaking the insulation layer on the surface of the same coil clamped in the two shaping devices and conducting electrical heating.

[0016] Although the preferred embodiments of the present invention have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0017] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
