[0049] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0050] Example 1:
[0051] like Figures 1 to 6 As shown, this utility model provides a motor magnet insertion fixture, including: a magnet insertion fixture 1, a cylinder 101 is provided on the magnet insertion fixture 1, a pressure plate 102 is arranged at the output end of the cylinder 101, a guide rod 103 is arranged on the pressure plate 102, and a protective structure for protecting the processing area in front of the magnet insertion fixture 1 is arranged on the magnet insertion fixture 1.
[0052] The protective structure includes a U-shaped frame 2 arranged on the magnet insert fixture 1, a movable baffle 201 slidably installed on the U-shaped frame 2, two transmission sprockets 202 rotatably installed inside the U-shaped frame 2, a transmission chain 203 installed on the two transmission sprockets 202, and a connecting rod 204 arranged on the transmission chain 203 and the guide rod 103. The movable baffle 201 is arranged on the side of the transmission chain 203 away from the connecting rod 204. During the descent of the guide rod 103, it will drive one side of the connecting rod 204 to descend. The descending connecting rod 204 will pull the transmission chain 203 to move, so that the transmission chain 203 will perform circumferential motion through the transmission cooperation with the transmission sprockets 202. This will cause the other side of the connecting rod 204 to drive the movable baffle 201 to rise. The rising movable baffle 201 can block the processing area in front of the magnet insert fixture 1.
[0053] The protective structure also includes a guide groove 205 inside the movable baffle 201, and a guide strip 206 arranged on one side of the U-shaped frame 2 and slidably installed inside the guide groove 205. The rising movable baffle 201 can slide on the guide strip 206 through the guide groove 205. The setting of the guide groove 205 and the guide strip 206 restricts the movement direction of the movable baffle 201 and improves the stability of the movement of the movable baffle 201.
[0054] Example 2:
[0055] Based on Embodiment 1, in order to prevent workers from reaching their hands under the pressure plate 102, a lever structure is provided in the guard structure to pull the user's arm away from under the pressure plate 102.
[0056] The lever structure includes a bearing 3 arranged on one side of the movable baffle 201, a bidirectional lead screw 301 rotatably installed inside the bearing 3, a linkage gear 302 arranged at one end of the bidirectional lead screw 301, a fixed rack 303 arranged on the inner wall of the U-shaped frame 2, the fixed rack 303 meshing with the linkage gear 302, and two levers 304 symmetrically threaded on the bidirectional lead screw 301. When the movable baffle 201 rises, it drives the bidirectional lead screw 301 and the linkage gear 302 to rise and move through the bearing 3, so that the moving linkage gear 302 rotates by meshing with the fixed rack 303. The rotating linkage gear 302 drives the two levers 304 to move through the bidirectional lead screw 301. If the arm extends into the processing area of the magnetic steel insertion fixture 1 during the rising process of the movable baffle 201, the moving levers 304 can push the arm away to prevent the hand from being below the pressure plate 102.
[0057] The lever structure also includes a T-shaped bar 305 arranged on one side of the movable baffle 201 to guide the lever 304 to move horizontally. The T-shaped bar 305 is slidably installed inside the lever 304. When the movable baffle 201 moves, it can slide horizontally along the direction of the T-shaped bar 305, thereby limiting the direction of movement of the movable baffle 201 and preventing it from deviating.
[0058] Example 3:
[0059] Based on Example 1, in order to control the cylinder 101 to stop operating in time when the worker puts his hand into the working area of the magnet insert tool 1, a pressing structure for emergency stopping of the magnet insert tool 1 when it is squeezed is arranged on the guard structure.
[0060] The pressing structure includes a fixed plate 4 arranged on one side of the movable baffle 201, a slide rod 401 slidably installed inside the fixed plate 4, a pressure strip 402 arranged at one end of the slide rod 401, an emergency stop switch 403 arranged above the fixed plate 4 to control the cylinder 101 to stop its extension and retraction, the emergency stop switch 403 being electrically connected to the cylinder 101, a limiting component arranged on the slide rod 401 to prevent the slide rod 401 from slipping off the fixed plate 4, and a reset component arranged on the pressure strip 402 to drive the pressure strip 402 to move and reset. If the arm is not pushed away in time, the continuous rise of the movable baffle 201 can cause the pressure strip 402 to press against the arm. At this time, the continuous rise of the movable baffle 201 will cause the fixed plate 4 to slide on the slide rod 401. At the same time, the rising fixed plate 4 will cause the emergency stop switch 403 to contact the pressure strip 402, so that the pressure strip 402 triggers the emergency stop switch 403 to control the cylinder 101 to stop operating.
[0061] Specifically, the limiting component includes a stop 404 arranged at one end of the slide bar 401. The stop 404 is located below the fixing plate 4. Through the cooperation of the stop 404 and the pressure strip 402, it can block both ends of the slide bar 401 to prevent the slide bar 401 from coming loose from the fixing plate 4.
[0062] Specifically, the reset assembly includes a spring 405 that is slidably sleeved on the slide bar 401. The two ends of the spring 405 are respectively arranged between the fixed plate 4 and the pressure bar 402. When the pressure bar 402 is pressed against the arm, the continuously rising fixed plate 4 will compress the spring 405. When the arm is disengaged from the pressure bar 402, the spring 405 will push the pressure bar 402 to move and reset, so that the pressure bar 402 is disengaged from the emergency stop switch 403, so that the magnetic steel insertion tool 1 can be used again.
[0063] Working principle:
[0064] In use, the motor stator can be placed on the processing table of the magnet insertion fixture 1. Then, the cylinder 101 is activated to control the pressure plate 102 to descend and press the stator so that the magnet can be inserted. During the descent of the pressure plate 102, the guide rod 103 will slide on the magnet insertion fixture 1, guiding the movement of the pressure plate 102. During the descent of the guide rod 103, one side of the connecting rod 204 will descend and move. The descending connecting rod 204 will pull the transmission chain 203 to move, so that the transmission chain 203 passes through the transmission sprocket 202. The transmission mechanism enables the connecting rod 204 to rotate in a circular motion, thereby causing the other side of the connecting rod 204 to drive the movable baffle 201 to move upward. The rising movable baffle 201 can block the processing area of the magnetic steel insertion tool 1, preventing the operator from extending their arm into the processing area. When the movable baffle 201 rises, it will drive the bidirectional lead screw 301 and the linkage gear 302 to move upward through the bearing 3. This causes the moving linkage gear 302 to rotate by meshing with the fixed rack 303. The rotating linkage gear 302 can drive the... The bidirectional lead screw 301 rotates. Both ends of the bidirectional lead screw 301 have threads facing opposite directions, and these threads are adapted to the levers 304. This allows the bidirectional lead screw 301 to rotate and, through its threaded engagement with the two levers 304, drive them to move in opposite directions. This enables the levers 304 to move horizontally while the movable baffle 201 rises. If, during the rising process of the movable baffle 201, the arm extends into the processing area of the magnet insert fixture 1, the moving levers 304 can push the arm away. To prevent the hand from being positioned below the pressure plate 102, if the arm is not moved away in time, the continuous rise of the movable baffle 201 will cause the pressure bar 402 to press against the arm. At this time, the continuous rise of the movable baffle 201 will cause the fixed plate 4 to slide on the slide bar 401. Simultaneously, the rising fixed plate 4 will compress the spring 405 and cause the emergency stop switch 403 to contact the pressure bar 402, causing the pressure bar 402 to trigger the emergency stop switch 403 to control the cylinder 101 to stop operating, preventing the cylinder 101 from continuously pressing down and improving the safety of operation.
[0065] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
