Currently, when installing the short-circuit ring, it is necessary to manually insert the short-circuit ring into the short-circuit ring groove, and then perform the clamping and closing operations, so the efficiency is very low. Summary of the invention

DETAILED DESCRIPTION

[0015] Embodiments of the present utility model: Figures 1 to 5As shown, a device for automatically loading short-circuit rings of stator punching sheets comprises a machine platform 1 and a guide rail 2. The guide rail 2 is installed on the machine platform 1 to limit the two sides of the stator punching sheets so that the stator punching sheets are transported along the length direction of the guide rail 2, comprising a sorting and conveying mechanism, a lifting mechanism, and a plurality of short-circuit ring pushing mechanisms. The sorting and conveying mechanism evenly transports the stator punching sheets on the guide rail 2 into and out of the lifting mechanism at intervals. The lifting mechanism comprises a cylinder 4 and a lifting platform 5. The cylinder 4 is the lifting device described above. The cylinder 4 is located below the guide rail 2. The lifting platform 5 is installed on the guide rail 2 and is telescopically lifted and lowered by the cylinder 4. When the lifting platform 5 is in a low position, the top surface of the lifting platform 5 is flush with the support surface of the guide rail 2. When it is in a high position, the stator punching sheets on the lifting platform 5 cooperate with the short-circuit ring pushing mechanism. The short-circuit ring pushing mechanism comprises a body 6 with a pushing groove therein, a slide rail 7, and a pushing device 9. The pushing groove is vertically arranged. A feed port connected to the push groove is provided on the body 6. The slide rail 7 is used for conveying the short-circuit ring 8 and is connected to the feed port. The short-circuit ring 8 is slid into the push groove in sequence. The pushing device 9 includes a driver and a push rod. The push rod is driven by the driver to slide in the push groove to push out the internal short-circuit ring to cooperate with the stator punching sheet. In order to achieve uniform interval conveying of the stator punching sheet, the stator punching sheet can be accurately placed at a fixed position on the lifting platform 5 so that it can accurately cooperate with the short-circuit ring pushing mechanism. The stator punching sheet on the guide rail 2 is realized by a sorting and conveying mechanism, wherein the sorting and conveying mechanism includes a displacement device and a limit device 11. The limit device includes a plurality of horizontally distributed limit rods 10. The distance between adjacent limit rods 10 is the same as the width of the stator punching sheet. The displacement device is connected to the limit device to drive the limit device 11 to move in the front and back and left and right directions. When in use, Figures 2 to 3 As shown, when the limiting device 11 moves forward, the stator punching sheet is limited between the two limiting rods 10 on the leftmost side, and the displacement device drives the limiting device to move rightward by a set distance, and then the displacement device moves backward to separate from the stator punching sheet, and then moves leftward to reset; the above operation is repeated, so that the stator punching sheet is continuously conveyed to the right at a certain interval, and after the stator punching sheet is conveyed to the lifting platform 5 located at a low position, as shown in FIG. Figure 1 As shown, the limit device 11 moves backward and separates from the stator punching sheet, and the cylinder 4 lifts the lifting platform 5 to the upper position. At this time, the stator punching sheet on the lifting platform 5 cooperates with the short-circuit ring pushing mechanism (the stator punching sheet is aligned with the pushing groove outlet of the body 6), and the short-circuit ring 8 on the slide rail 7 enters the pushing groove through the feed port. After the short-circuit ring falls, it is aligned and matched with the short-circuit ring groove on the stator punching sheet. Driven by the driver, the push rod moves downward in the pushing groove to push the short-circuit ring into the short-circuit ring groove of the stator punching sheet. After the lifting platform 5 descends to the low position, the limit device 11 first moves to the left to reset, and then moves forward to be plugged with the stator punching sheet and then moves to the right for transportation, so that the stator punching sheet is moved to the right for transportation in sequence at a fixed interval, so that the stator punching sheet to be installed on the left side is transported to the lifting platform 5 and the installed stator punching sheet is output from the right side, so as to realize the automatic installation of the short-circuit ring and the stator punching sheet.

[0016] As a preferred embodiment, in order to enable the stator punching sheets to be installed to be accurately matched with the sequence conveying mechanism, the stator punching sheets to be installed need to be placed at a specific position, so a pushing device 17 and a positioning device are set, wherein the pushing device 17 is arranged at the input end of the guide rail 2, that is, at the leftmost end of the guide rail 2, to push the stator punching sheets entering the guide rail 2 to the right, and the positioning device includes a blocking rod 12 and a cylinder 1, and the cylinder 1 is the driver. The blocking rod 12 blocks and cooperates with the stator punching sheets pushed by the pushing device through the telescopic movement of the cylinder 1. The pushing device 17 can be a cylinder, which pushes the stator punching sheets entering the guide rail 2 in sequence through telescopic movement, and the stator punching sheets pushed after being pushed are The sheet is blocked by the extended blocking rod 12 so that it stays at a specific position on the guide rail 2, and then the blocking rod 12 retracts to release the blockage. After the sequencing conveying mechanism conveys it, the next stator punch is conveyed to a specific position, and this cycle is repeated. In order to automatically input the stator punch to the left side of the guide rail 2 for the pushing device to push, a conveyor belt 14 can be connected to the input end of the guide rail 2, and a sensor is set at the input end of the guide rail 2. When the stator punch enters the input end of the guide rail 2, the conveyor belt 14 stops after being sensed by the sensor. After the stator punch entering the input end of the guide rail 2 is pushed by the pushing device, the conveyor belt 14 runs again to transport the next stator punch.

[0017] As a preferred embodiment, a measuring device is included, which includes a sensor 15 and a lifter 16. The sensor 15 is a contact sensor. The lifter is lifted and contacted with the stator punching sheet resting at a specific position on the guide rail 2 to measure the height of the stator punching sheet. On the one hand, the stator punching sheet with abnormal height has a high possibility of quality problems itself, and on the other hand, there are problems in coordination with the short-circuit ring pushing mechanism. Therefore, it should be noted that the measuring device can be connected to the control device. When a stator punching sheet with abnormal height appears, an alarm is issued, the equipment is stopped, the abnormal stator punching sheet is eliminated, and the product quality is improved.
