[0042] Specifically, in the initial stage when the twisted horizontal shaft 301 rotates and drives the centrifugal disc 302 to rotate, the second torsion limiting block 307 gradually approaches the first torsion limiting block 306 and has not yet been released from the first torsion limiting block 306. The rotation of the centrifugal disc 302 generates centrifugal force, which throws the multiple slide bars 309 outward along the inner walls of the multiple centrifugal slide holes 308. The multiple slide bars 309 extend toward the periphery, causing the multiple reset springs 3010 to be stretched to generate elastic force. After the multiple slide bars 309 extend, the top arc-shaped top tiles 3015 are respectively pushed outward.

[0043] When the top contact 207 and the bottom contact 2011 are adjusted to the appropriate positions, the motor 3025 is turned off, so that the twisted horizontal shaft 301 and the centrifugal disk 302 stop rotating, causing the centrifugal force on the multiple slide bars 309 to disappear, and the resilience of the multiple reset springs 3010 is released, so that the multiple slide bars 309 are retracted into the interior of the centrifugal slide hole 308, that is, the upward thrust of the slide bar 309 on the top arc-shaped top tile 3015 and the downward thrust on the bottom arc-shaped top tile 3020 disappear, and the resilience of the top spring 2030 pushes the top insulating push head 206 together with the top contact 207 to move downward, while the resilience of the bottom spring 2012 pushes the bottom insulating push head 2010 together with the bottom contact 2011 to move upward, so that the ends of the top contact 207 and the bottom contact 2011 are respectively in contact with the top and bottom surfaces of the stator punching sheet again, and the power is turned on to test the insulation performance of the stator punching sheet.

[0044] Embodiment 4

[0045] A fixing seat 5 is fixedly installed on the side surface where the two side frames 1 are close to each other. The fixing seat 5 is located on the top of the centrifugal disc 302, and the fixing seat 5 is located between the front and rear top vertical push rods 3013. The height of the fixing seat 5 corresponds to the height of the top contact 207 and the height of the bottom contact 2011. An electric push rod 6 is fixedly installed on the top wall of the two side frames 1. A pressure block 7 is fixedly installed on the top of the output shaft of the electric push rod 6. The pressure block 7 is located on the top of the fixing seat 5.

[0046] Specifically, the punching sheet is placed on the top of the two left and right fixing seats 5, and the stator punching sheet is passed through the top contact 207 and the bottom contact 2011, so that the bottom of the top contact 207 just contacts the top surface of the stator punching sheet, and the top of the bottom contact 2011 just contacts the bottom surface of the stator punching sheet. The power is turned on and the insulation performance of the stator punching sheet is tested.

[0047] When the stator punching insulation performance detection device of the present embodiment is in operation, the stator punching to be detected is placed on the top of the two left and right fixing seats 5, and the stator punching is passed between the top contact 207 and the bottom contact 2011, so that the bottom of the top contact 207 just contacts the top surface of the stator punching, and the top of the bottom contact 2011 just contacts the bottom surface of the stator punching, and the power is turned on to detect the insulation performance of the stator punching;

[0048] The output shaft of the motor 3025 drives the torsionally connected horizontal shaft 301 to rotate, thereby driving a centrifugal disk 302 connected to the torsionally connected horizontal shaft 301 to rotate. While the torsionally connected horizontal shaft 301 rotates, the driving pulley 401, the power belt 404, the driven pulley 403 and the driven shaft 402 drive another torsionally connected horizontal shaft 301 to rotate together with the centrifugal disk 302. The centrifugal disk 302 rotates, driving the second torsion limiting block 307 to rotate. When the second torsion limiting block 307 rotates and abuts against the first torsion limiting block 306, the rotational torque of the centrifugal disk 302 is transmitted to the connecting disc 305 through the second torsion limiting block 307 and the first torsion limiting block 306, thereby driving the adjusting screw rod 20 connected to the connecting disc 305. 16 rotates together, the adjusting screw rod 2016 rotates and the threaded connection with the internal thread seat 2015 drives the bottom carrier 202 to move left and right, the bottom carrier 202 moves left and right through the two bottom telescopic rods 209 to drive the bottom insulating push head 2010 together with the bottom contact 2011 to move together, at the same time, the bottom carrier 202 moves left and right through the two front and rear connecting vertical bars 203 to drive the top carrier 201 to move together, the top carrier 201 moves left and right through the two top telescopic rods 205 to drive the two top insulating push heads 206 together with the top contact 207 to move left and right, and other parts of the stator punching can be detected by moving the top contact 207 and the bottom contact 2011 left and right;

[0049] In addition, the twisted horizontal shaft 301 rotates, driving the centrifugal disc 302 to rotate in the initial stage. In the process in which the second torsion limit block 307 gradually approaches the first torsion limit block 306 and has not yet been released from the first torsion limit block 306, the rotation of the centrifugal disc 302 generates centrifugal force, which throws the multiple slide bars 309 outward along the inner walls of the multiple centrifugal slide holes 308. The multiple slide bars 309 stretch outward, causing the multiple reset springs 3010 to be stretched to generate elastic force. After the multiple slide bars 309 stretch, the top arc-shaped top tiles 3015 are respectively pushed outward. The top arc-shaped roof tile 3015 moves upward and pushes the bottom arc-shaped roof tile 3020 downward, and the top arc-shaped roof tile 3015 moves upward through the two top vertical push rods 3013 to drive the top vertical push block 3014 to move upward together, and the top vertical push block 3014 moves upward to drive the top sliding sleeve 3017 and the top connecting beam 3018 to move upward, and the top connecting beam 3018 moves upward to drive the two top telescopic rods 205 together with the top insulating push head 206 and the top contact 207 to move upward, and the top spring 2030 is compressed. The bottom arc-shaped top tile 3020 moves downwards through the two bottom vertical push rods 3019, driving the bottom vertical push block 3021 to move downwards, the bottom vertical push block 3021 moves downwards and drives the bottom vertical push cross bar 3022 to move downwards together, the bottom vertical push cross bar 3022 moves downwards through the bottom sliding sleeve 3023, driving the bottom connecting cross beam 3024 to move downwards, the bottom connecting cross beam 3024 moves downwards through the two bottom telescopic rods 209, driving the bottom insulating push head 2010 together with the bottom contact 201 1 moves downward, the bottom spring 2012 is compressed and stores force, so that the ends of the top contact 207 and the bottom contact 2011 can be separated from the surface of the stator punching sheet by the upward movement of the top contact 207 and the downward movement of the bottom contact 2011, that is, the top contact 207 and the bottom contact 2011 will not directly rub against the stator punching sheet during the left and right movement, thereby extending the service life of the top contact 207 and the bottom contact 2011, and avoiding scratches on the surface of the stator punching sheet during the detection;

[0050] When the top contact 207 and the bottom contact 2011 are adjusted to the appropriate positions, the motor 3025 is turned off, so that the twisted horizontal shaft 301 and the centrifugal disk 302 stop rotating, causing the centrifugal force on the multiple slide bars 309 to disappear, and the resilience of the multiple reset springs 3010 is released, so that the multiple slide bars 309 are retracted into the interior of the centrifugal slide hole 308, that is, the upward thrust of the slide bar 309 on the top arc-shaped top tile 3015 and the downward thrust on the bottom arc-shaped top tile 3020 disappear, and the resilience of the top spring 2030 pushes the top insulating push head 206 together with the top contact 207 to move downward, while the resilience of the bottom spring 2012 pushes the bottom insulating push head 2010 together with the bottom contact 2011 to move upward, so that the ends of the top contact 207 and the bottom contact 2011 are respectively in contact with the top and bottom surfaces of the stator punching sheet again, and the power is turned on to test the insulation performance of the stator punching sheet.
