Technical Field

[0001] The utility model relates to the technical field of stator slot paper inserting machines, in particular to a motor stator slot paper inserting machine. Background Art

[0002] Inserting insulating paper into the motor stator slots is a necessary step in the processing. It mainly avoids electrical connection between the iron core and the enameled wire winding, and provides an effective insulation foundation and a certain compressive mechanical strength for the subsequent coils.

[0003] At present, the stator slot paper insertion machine still has certain disadvantages during use. Since the insulating paper is cut and molded before being inserted into the stator slot, the insulating paper easily exceeds the specified length of the stator slot, and the evenly distributed insulating paper penetrates to the outside of the stator slot and the excessively long parts are uneven. At the same time, each stator replacement requires the equipment to be shut down, which affects the paper insertion efficiency.

[0004] In view of this, a motor stator slot paper inserting machine is designed to solve the above problems. Utility Model Content

[0028] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0029] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0030] A motor stator slot paper inserting machine provided by some embodiments of the present invention will be described below with reference to the accompanying drawings. Example 1

[0031] Combine Figure 1-Figure 4 As shown, the utility model provides a motor stator slot paper inserting machine, comprising a paper inserting machine (100) and a plurality of stators (400), a bearing transmission mechanism (200) arranged in the paper inserting machine (100), and three sets of paper calibration mechanisms (300) arranged on the bearing transmission mechanism (200), wherein the bearing transmission mechanism (200) is used to provide a lateral driving force and a rotational driving force for the plurality of sets of paper calibration mechanisms (300), and the paper calibration mechanism (300) is used to provide a limit protection for the assembled stators (400) and provide a calibration limit for the inserted insulating paper.

[0032] The bearing transmission mechanism (200) comprises a chain (240), a rotation-assisting base (230) arranged in the paper inserting machine (100), a clamping seat (250) arranged at the outer end of the rotation-assisting base (230), a hydraulic component (260) arranged in the clamping seat (250), a sleeve (270) installed on the hydraulic sub-rod in the hydraulic component (260), a bracket (280) arranged outside the sleeve (270), a chassis (210) fixedly mounted on the inner wall of the paper inserting machine (100), and a motor (220) arranged in the chassis (210);

[0033] Three sets of paper calibration mechanisms (300) are arranged in three ends of the bracket (280);

[0034] The paper calibration mechanism (300) comprises a position-limiting cushion (310), three pads (360), and three position-limiting clamps (350) arranged on the position-limiting cushion (310).

[0035] The stator slot paper inserting machine still has certain defects during actual use. After the insulating paper is evenly inserted into the stator slot, the insulating paper cut to the specified size exceeds the stator and the layers are uneven. At the same time, the paper inserting machine needs to be shut down every time the stator is replaced, which will lead to low working efficiency of the paper inserting machine.

[0036] The device is configured by arranging a rotation-assisting base (230) on the paper inserting machine and fixing the clamping seat (250) to the rotation-assisting base (230) with bolts. At this time, the hydraulic component (260) fixed in the clamping seat (250) and placed horizontally can provide a sufficiently stable pressure-bearing platform for the sleeve (270) and the bracket (280). At this time, the three sets of paper calibration mechanisms (300) assembled in the three ends of the bracket (280) can carry the three loaded stators (400) to continuously insert paper without stopping the machine. During each paper inserting operation, the worker can replace a stator (400) covered with insulating paper. Example 2

[0037] Combine Figure 1-Figure 3 As shown, in the above embodiment, a gear is installed on the internal transmission shaft of the motor (220);

[0038] The gear is transmission-connected to one end of the chain (240), while the other end of the chain (240) is transmission-connected to the gear end of the rotation-assisting base (230) penetrating to the inner cavity of the paper inserting machine (100).

[0039] Preferably, the bracket (280) is made of stainless steel, and the number of ends of the bracket (280) can be determined according to the number of stators (400) actually loaded.

[0040] When in use, the motor (220) drives the chain (240) when in operation, thereby transmitting the auxiliary rotation base (230). At this time, the clamping seat (250) and the hydraulic component (260) control the sleeve (270) and the bracket (280) to move horizontally stably, while driving the evenly distributed multiple sets of paper calibration mechanisms (300) to rotate along the rotating shaft of the paper inserting machine (100), so that the stator (400) can be freely loaded and unloaded without stopping the paper inserting machine (100). Example 3

[0041] Combine Figure 1 and Figure 4 As shown, in the above embodiment, a cross-shaped insert rod is provided at the inner end of the limiting pad (310), an annular groove is provided at the inner end of the limiting pad (310), and a cylindrical hole is provided in the inner cavity of the limiting pad (310);

[0042] A plug (320) is provided in the cylindrical hole, and the plug (320) is connected to a pull rod (330) and a tension spring (340) connected between the pull rod (330) and the limiting pad (310).

[0043] Preferably, the limiting pad (310) has the same diameter and width as the rotating shaft in the paper inserting machine (100), and the limiting pad (310) and the rotating shaft form a sufficiently stable pressure-bearing platform for the stator (400), and the three limiting clamps (350) arranged outside the limiting pad (310) and distributed in a triangular shape can provide limiting protection for the outer end of the stator (400), and the annular groove at the inner end of the limiting pad (310) can avoid the problem of uneven layers in the excessively long portion of the insulating paper.

[0044] A horizontal positioning rod (370) is provided in the pad (360), and a spring (380) is provided on the positioning rod (370);

[0045] The limiting fixture (350) is composed of an arc-shaped limiting plate, an L-shaped baffle, and two push rods, and the ends of the two push rods passing through the columnar holes are provided with grooves that fit the inclined surface of the plug (320);

[0046] One end of the spring (380) bears pressure on the L-shaped baffle.

[0047] Preferably, the tension spring (340) pulls the pull rod (330) toward the inner cavity of the limiting pad (310), and at this time the plug (320) fixedly installed at the inner end of the pull rod (330) will shrink into the cylindrical hole. At this time, the three sets of L-shaped baffles will lose the squeezing force of the plug (320), and under the elastic thrust of the three springs (380), the three limiting clamps (350) will quickly provide limiting protection for the stator (400) assembled on the rotating shaft.

[0048] The working principle and use process of the present invention are as follows: the hydraulic component (260) is operated in advance, and when the hydraulic sub-rod in the hydraulic component (260) extends outward, the sleeve (270) and the bracket (280) installed on the outer end of the hydraulic sub-rod are pushed outward horizontally, and at this time, the three sets of paper calibration mechanisms (300) arranged in the three ends of the bracket (280) are moved outward at the same time;

[0049] Then, according to the needs, the three pull rods (330) are stretched outward in turn, and the plug (320) pulled by the pull rod (330) will squeeze the three limit clamps (350), and at this time the three limit clamps (350) will expand outward, and then the three stators (400) are respectively assembled on the outside of the three limit pads (310). After the pull rod (330) is released, it is elastically pressed by the spring (380), and the limit clamps (350) will provide limit constraints on the outer wall of the stator (400);

[0050] After the three stators (400) are supported by the three sets of paper calibration mechanisms (300), the hydraulic rod in the hydraulic component (260) contracts and resets, and one of the stators (400) is pushed toward the rotating shaft of the paper inserting machine (100). As the rotating shaft in the paper inserting machine (100) drives the stator (400) at that location to rotate at a uniform speed until the insulating paper is evenly distributed in the slots inside the stator (400), the stator (400) filled with insulating paper can be pushed outward according to the above steps. As the motor (220) starts, the gear on its internal transmission shaft drives the chain (240) and the auxiliary rotation base (230). At this time, the other two stators (400) can rotate toward the position of the rotating shaft of the paper inserting machine (100).
