DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0019] An embodiment of the utility model, as Figure 1 As shown, the grinding mechanism 2 is provided with at least two groups and is symmetrically arranged on the upper and lower sides of the feeding mechanism 3. The grinding mechanism 2 is movably mounted on the vertically arranged bidirectional screw 4 through the screw sleeve 5. The two ends of the bidirectional screw 4 are mounted on the first mounting plate 1 through the connecting plate 6. A servo motor 7 connected to the bidirectional screw 4 is arranged on the top of the connecting plate 6. The grinding mechanism 2 includes a vertically arranged second mounting plate 21. A pulley assembly is arranged on the side of the second mounting plate 21 away from the first mounting plate 1. A driving motor 25 is arranged on the side of the second mounting plate 21 close to the first mounting plate 1. The back side of the second mounting plate 21 is fixedly connected to the screw sleeve 5, so that the two surfaces of the flat enameled wire can be ground simultaneously. The position of the grinding mechanism is adjusted in time according to the wear condition of the grinding belt, so as to improve the grinding effect, have a high degree of automation, and reduce the labor production cost.

[0020] The feeding mechanism 3 includes two groups of horizontally arranged feeding rollers 31. A cleaning assembly is provided on the side of the feeding roller 31 close to the output position. The cleaning assembly is composed of cleaning rollers 32 arranged on both sides of the enameled wire. A tensioning roller 32 is provided between the cleaning assembly and the feeding roller 31. After the polishing is completed, the enameled wire passes through the double-sided cleaning rollers 32 to clean the dust remaining on the surface, so as to ensure the yield of the subsequent processing of the product.

[0021] A cover shell 27 fixed on the second mounting plate 21 is provided on the outside of the pulley assembly. The cover shell 27 is used to protect the pulley assembly and facilitate the replacement of the grinding belt 24. The pulley assembly includes a driven wheel 23 close to the feeding mechanism 3 and a driving wheel 22 away from the driven wheel 23. The grinding belt 24 is installed on the driving wheel 22 and the driven wheel 23. The rotating shaft of the driving wheel 22 is connected to the output shaft of the driving motor 25. The driving motor 25 controls the rotation of the pulley assembly. The rotating grinding belt 24 grinds both sides of the enameled wire at the same time, thereby improving the grinding efficiency.

[0022] The second mounting plate 21 is provided with a detection module 9 on one side of the pulley assembly. The detection module 9 includes a detection plate and a detection head arranged on both sides of the grinding belt 24. The detection module 9 is electrically connected to the servo motor 7. When the grinding belt 24 is worn, the detection module 9 detects the thickness change of the worn position of the grinding belt 24, and controls the servo motor 7 to adjust the spacing of the grinding mechanism 2 after data processing to ensure the grinding efficiency.

[0023] A U-shaped connecting block 26 is provided on the side of the second mounting plate 21 away from the pulley assembly. The connecting block 26 is fixedly connected to the screw sleeve 5 by bolts. The screw sleeve 5 is threadedly connected to the bidirectional screw 4 to convert the rotational motion of the bidirectional screw 4 into the linear motion of the screw sleeve 5.

[0024] The bidirectional screw rod 4 is symmetrically provided with left-handed threads and right-handed threads. Both ends of the bidirectional screw rod 4 are mounted on the connecting plate 6 through movable bearings. The upper and lower grinding mechanisms are respectively mounted on the bidirectional screw rod 4. When the servo motor 7 controls the rotation of the bidirectional screw rod 4, the two sets of grinding mechanisms 2 can realize synchronous movement in the same or reverse directions, thereby improving the position accuracy of the grinding mechanism 2.

[0025] An exhaust fan 8 is arranged behind the grinding mechanism 2 near the enameled wire. The exhaust fan 8 is installed on the first mounting plate 1 through an exhaust pipe on one side close to the bidirectional screw 4. The dust generated during the grinding process is collected and processed by the exhaust fan to maintain the workshop production environment and ensure the health of workers.

[0026] The working principle of this embodiment is: control the servo motor to move the grinding mechanism to the upper limit and the lower limit respectively, open the cover and replace the grinding belt of the corresponding specification, after the preparation work is completed, install the enameled wire on the feeding mechanism for continuous feeding, and the servo motor controls the grinding mechanism to move toward each other until the grinding belt contacts both sides of the enameled wire for grinding, thereby realizing the double-sided automatic grinding of the flat enameled wire. When the detection module located in the grinding mechanism detects that the thickness change of a certain position of the grinding belt exceeds the threshold, the servo motor controls the two groups of grinding mechanisms to move toward each other to reduce the distance, thereby avoiding the impact of the grinding quality due to the change of the grinding belt thickness.

[0027] Several points that need to be explained are: First, in the description of the present application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, and can be mechanical or electrical connections, or internal connectivity between two elements, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative position relationships. When the absolute position of the object being described changes, the relative position relationship may change; secondly, in this article, relational terms such as first and second, etc. are only used to distinguish one entity from another, and do not necessarily require or imply that there is any such actual relationship or order between these entities.

[0028] The above examples are merely illustrative of the present utility model and do not constitute a limitation on the protection scope of the present utility model. All designs that are identical or similar to the present utility model fall within the protection scope of the present utility model.
