The remaining structures of the instantaneous action characteristic test table of a small circuit breaker are not fully illustrated. The specific detection principle can refer to the prior art. A material change rack 2 is fixedly connected to the test table 101, and a rotating connection on the material change rack 2 A material changing shaft 201 is connected, a material changing plate 202 is fixedly connected to the material changing shaft 201, and the material changing plate 202 is provided with two slideways, and a material changing slide bar 203 is slidably connected in each slideway, and the material changing slide bar 203 can slide into the slideway provided on the material changing plate 202, and the sliding direction of the material changing slide bar 203 is perpendicular to the material changing shaft 201, and a material changing spring 208 is sleeved on the material changing slide bar 203, and the material changing spring 208 will be compressed when the material changing slide bar 203 slides into the slideway on the material changing plate 202, and a material changing shaft sleeve 204 is fixedly connected to the end of the material changing slide bar 203 away from the material changing plate 202, and the two A flip shaft 205 is connected to the material changing shaft sleeve 204 in a damping rotation manner to prevent the flip shaft 205 from rotating at will through a damping effect. A loading platform 206 is fixedly connected to the flip shaft 205. Two electric clamps 207 for clamping the circuit breaker are slidably connected to the loading platform 206. The electric clamps 207 are existing technologies. The two electric clamps 207 can move relative to each other under the drive of electricity. By rotating the material changing shaft 201, the position of the electric clamps 207 can be adjusted to facilitate approaching the circuit breaker. By rotating the flip shaft 205, the direction of the electric clamps 207 can be adjusted to facilitate clamping and placing the circuit breaker.

[0027] When it is necessary to place a circuit breaker on the pneumatic slide 102 for testing, first control the material changing shaft 201 to rotate 180 degrees clockwise. During the rotation of the material changing shaft 201, control the flip shaft 205 to rotate clockwise as well, so that the electric clamping plate 207 is adjusted to a downward state to facilitate clamping the circuit breaker. Then control the electric clamping plate 207 to clamp the protruding position on the upper side of the circuit breaker, and then control the material changing shaft 201 to rotate 180 degrees counterclockwise to reset. During this process, the circuit breaker to be tested is transported into the clamping range of the electric clamping plate 207 for easy clamping again, and control the flip shaft 205 to rotate counterclockwise to reset. 207 will place the circuit breaker on the pneumatic slide 102, then control the pneumatic clamp 103 to clamp the circuit breaker, and then control the test plugs 104 on both sides to insert into the wiring terminals of the circuit breaker to start the test. The specific test principle can refer to the instantaneous action characteristic test bench of the small circuit breaker in the prior art, which will not be repeated here; after the detection is completed, the pneumatic slide 102 is controlled to slide to the left to the unloading station, and then the circuit breaker that has been tested is removed from the pneumatic slide 102, and then the pneumatic slide 102 is controlled to reset to the right, and the material changing mechanism is controlled to place the next circuit breaker to be tested on the pneumatic slide 102, and the operation is cyclic.

[0028] like Figure 1 , Figure 4 and Figure 5 As shown, it also includes a flip assembly for driving the flip shaft 205 to rotate. The flip assembly is connected to the flip shaft 205. The flip assembly includes a guide frame 3, a guide frame 301, a flip rack 302 and a flip gear 303. The guide frame 3 is fixedly connected to the upper side of the detection platform 101. Two guide frames 301 are symmetrically fixedly connected to the guide frame 3. The guide frame 301 is composed of two sections of slides, one of which is an arc shape, and the diameter of the arc shape is the same as the rotation path of the flip shaft 205, and the other section of the slide is a vertically arranged straight line, and the straight line slide is located on the side away from the detection platform 101. The flip rack 302 is fixedly connected to the guide frame 301, and the flip rack 302 is located on the opposite side of the two guide frames 301. The flip gear 303 is fixedly connected to the flip shaft 205, and the flip gear 303 will engage with the flip rack 302 when the material changing shaft 201 drives the flip shaft 205 to revolve.

[0029] like Figure 4 and Figure 5As shown, it also includes a guide assembly for fixing the direction of the electric splint 207, the guide assembly is connected to the flip shaft 205, the guide assembly includes a limited rotation rod 4 and a limited rotation block 401, each guide frame 301 is fixed with two limited rotation rods 4, the limited rotation rod 4 is located at the straight slide position on the guide frame 301, and the limited rotation rod 4 is located on the opposite side of the two guide frames 301, and both ends of the flip shaft 205 are fixed with the limited rotation block 401. When the flip shaft 205 moves to the straight slide position on the guide frame 301, the limited rotation block 401 will move between the two limited rotation rods 4 on the same side, and the limited rotation rod 4 limits the rotation of the flip shaft 205 through the limited rotation block 401.

[0030] like Figure 1 , Figure 2 and Figure 6 As shown, it also includes a feeding mechanism for conveying the circuit breaker to the clamping range of the material changing mechanism. The feeding mechanism is connected to the detection table 101. The feeding mechanism includes a feeding slide 5, a feeding table 501, a feeding plate 502 and a material box 503. The detection table 101 is provided with a feeding slide 5, and the feeding table 501 is connected to the feeding slide 5 in a horizontal sliding direction. The feeding table 501 is connected to the feeding plate 502 in a horizontal sliding direction, and the sliding directions of the feeding plate 502 and the feeding table 501 are perpendicular to each other. A square groove is provided on the top of the feeding plate 502, and a material box 503 is placed in the square groove. The material box 503 is used to store the circuit breaker to be tested. The position of the material box 503 can be adjusted by controlling the sliding of the feeding table 501 and the feeding plate 502, so as to move the circuit breaker in the material box 503 to the clamping range of the material changing mechanism.

[0031] The material box 503 is a material turnover box in the prior art. After the circuit breaker is produced, it will be stacked in the material box 503, and the circuit breakers in the material box 503 are stacked in a single layer with three vertical and four horizontal layers. When the circuit breaker needs to be tested, the worker will first place the material box 503 with the circuit breaker stacked in the groove on the feeding plate 502. When the material changing shaft 201 rotates clockwise by 140 degrees, the two sides of the flip shaft 205 will first move in the circular arc slideway on the guide frame 301. In this process, the flip rack 302 will drive the flip shaft 205 to rotate clockwise by 220 degrees through the flip gear 303, thereby adjusting the angle of the rotation limit block 401, so that the rotation limit block 401 can vertically enter between the two rotation limit rods 4, and the upper The material table 206 and the electric clamping plate 207 will be rotated to a vertical downward state. During the process of the material changing shaft 201 continuing to rotate forty degrees clockwise, the rotation limit block 401 slides downward between the two rotation limit rods 4, and the rotation limit rod 4 can limit the rotation of the rotation limit block 401, so that the material loading table 206 and the electric clamping plate 207 will move vertically downward, that is, the movement trajectory of the electric clamping plate 207 in this section of the stroke is a straight line, so as to clamp the circuit breaker below; during the process of the material changing shaft 201 first rotating forty degrees counterclockwise, the rotation limit block 401 slides upward between the two rotation limit rods 4, so that the movement trajectory of the electric clamping plate 207 in this section of the stroke is also a straight line. Since the circuit breakers are stacked together, if the electric clamping plate 207 moves in this section If the motion trajectory during the process is an arc, the clamped circuit breaker will be squeezed and collided with the adjacent circuit breaker, which will cause the adjacent circuit breaker to deviate, affecting the electric clamping plate 207 to clamp again. During the process of the material replacement shaft 201 continuing to rotate counterclockwise by 140 degrees, the flip rack 302 will drive the flip shaft 205 to rotate counterclockwise by 220 degrees through the flip gear 303, so that the loading platform 206 and the electric clamping plate 207 can be restored to a vertical downward state after rotating counterclockwise, so as to place the circuit breaker on the pneumatic slide 102; after the electric clamping plate 207 clamps the first circuit breaker, it first controls the feeding plate 502 to slide a distance of a circuit breaker away from the detection platform 101, and the distance is equal to the width of the circuit breaker. , thereby adjusting the position of the circuit breakers in the material box 503 in the longitudinal direction, so that the electric clamping plate 207 can clamp them again. After the circuit breakers in the first longitudinal column are clamped, the feeding plate 502 is controlled to slide and reset in the direction close to the detection table 101, and the feeding table 501 is controlled to move to the left a distance of a circuit breaker, and the distance is equal to the length of the circuit breaker, so as to adjust the position of the material box 503 in the transverse direction, so that the electric clamping plate 207 can clamp the circuit breakers in the next longitudinal column. By adjusting the position of the feeding plate 502 and the feeding table 501, the electric clamping plate 207 can clamp all the circuit breakers in the material box 503. After the circuit breakers in the material box 503 are clamped, the feeding plate 502 and the feeding table 501 are controlled to reset, and a new material box 503 is replaced.

[0032] Embodiment 2: Based on embodiment 1, Figure 4 and Figure 6 As shown, it also includes a longitudinal movement component for controlling the sliding of the feeding plate 502, the longitudinal movement component is connected to the feeding platform 501, and the longitudinal movement component includes a lifting rod 6, a reset spring 601, a force rod 602, a first ratchet bar 603, a feeding gear 604, a driven rack 605 and a pressure rod 606. There are two lifting rods 6 symmetrically connected to the feeding platform 501. The lifting rod 6 slides in the vertical direction. The lifting rod 6 is sleeved with a reset spring 601. When the lifting rod 6 slides downward, the reset spring 601 will be compressed. The two lifting rods 6 are commonly fixed with a force rod 602. A first ratchet bar 603 is fixedly connected to the rod 602, and a through hole is opened on the feeding platform 501 for the first ratchet bar 603 to pass downward. Two feeding gears 604 are symmetrically connected to the feeding platform 501 for rotation. The first ratchet bar 603 will drive the feeding gear 604 to rotate only when it moves upward. Two driven racks 605 are symmetrically fixedly connected to the feeding plate 502, and the feeding gear 604 and the driven rack 605 on the same side remain in meshing. A pressure rod 606 is fixedly connected to the flip shaft 205, and the pressure rod 606 is used to press the force-bearing rod 602 downward to make the lifting rod 6 slide downward.

[0033] After the flip shaft 205 rotates 220 degrees clockwise, the pressure rod 606 will be rotated to the outside. During the clockwise rotation of the material changing shaft 201, the pressure rod 606 that rotates to the outside will press the force-bearing rod 602 downward, thereby driving the lifting rod 6 and the first ratchet bar 603 to move downward, and the reset spring 601 will be compressed. During the downward movement of the first ratchet bar 603, it will first maintain meshing with the feeding gear 604, and then because there are no teeth on the upper side of the first ratchet bar 603, it will disengage from the feeding gear 604 again, and the first ratchet bar 603 will not drive the feeding gear 604 to rotate during the downward movement; during the counterclockwise rotation reset process of the material changing shaft 201 The middle electric clamp 207 will drive the circuit breaker in the material box 503 to move upward, and the reset spring 601 will push the lifting rod 6, the force rod 602 and the first ratchet bar 603 to reset upward. The first ratchet bar 603 will first keep the material box 503 out of mesh with the feeding gear 604, so that the material box 503 remains stationary to facilitate the removal of the circuit breaker. Then the first ratchet bar 603 engages with the feeding gear 604 and drives the feeding gear 604 to rotate counterclockwise. When the feeding gear 604 rotates, it will drive the feeding plate 502 to move away from the detection table 101 through the driven rack 605 by the distance of the circuit breaker, thereby realizing the function of moving the material box 503 in the longitudinal direction.

[0034] like Figure 1 and Figure 7As shown, it also includes a transverse movement component for controlling the movement of the feeding platform 501 and the reset of the feeding plate 502. The transverse movement component is connected to the feeding platform 501, and the transverse movement component includes a driving platform 7, a screw 701, a No. 1 motor 702, a slide 703, a push rod 704 and a reset plate 705. The driving platform 7 is fixedly connected to the base 1, and the driving platform 7 is rotatably connected to the screw 701. The driving platform 7 is fixedly connected to the motor 702, and the output shaft of the motor 702 is fixedly connected to the end of the screw 701. The slide 703 is threadedly connected to the screw 701, and the top of the slide 703 is fixedly connected to the feeding platform 501. The push rod 704 is fixedly connected to the screw 701, and the reset plate 705 is fixedly connected to the lower end of the feeding plate 502. During the rotation of the push rod 704, the reset plate 705 will be pushed to make the feeding plate 502 slide and reset in the direction close to the detection platform 101.

[0035] Since the lead screw 701 and the slide 703 are threadedly connected, the slide 703 can drive the feeding table 501 to move horizontally when the lead screw 701 rotates, thereby realizing the function of moving the material box 503 horizontally, and the rotation of the lead screw 701 will drive the push rod 704 to rotate. During the rotation of the push rod 704, the reset plate 705 will be pushed toward the direction close to the detection table 101, so that each time the feeding table 501 is moved horizontally, the feeding plate 502 can be driven to reset longitudinally, so as to continuously clamp the circuit breaker.

[0036] like Figure 1 As shown, there are two groups of material changing mechanisms, flipping assemblies and guide assemblies, and the sizes of the two groups are different. Technicians can determine the sizes of the two groups according to actual conditions. The right group of material changing mechanisms is used to take the circuit breaker to be tested in the material box 503 and place it on the pneumatic slide 102, and the left group of material changing mechanisms is used to take the circuit breaker on the pneumatic slide 102 for unloading.

[0038] After the material changing mechanism on the right places the circuit breaker on the pneumatic slide 102, the second motor 901 is controlled to drive the material changing shaft 201 in the left material changing mechanism to rotate counterclockwise by 180 degrees. During this process, the active gear 902 will drive the material changing shaft 201 in the right material changing mechanism to rotate clockwise by 180 degrees through the driven gear 903, so as to continue to clamp the circuit breaker in the material box 503 through the electric clamping plate 207 in the right material changing mechanism. When the circuit breaker is detected, the pneumatic slide 102 will move to the left to the unloading station, and the circuit breaker on the pneumatic slide 102 will move to the electric clamping plate 207 in the left material changing mechanism. The pneumatic slide 102 is within the clamping range of the movable clamp 207, and then the circuit breaker on the pneumatic slide 102 is clamped by the electric clamp 207 in the left material changing mechanism, and then the No. 2 motor 901 is controlled to drive the material changing shaft 201 in the left material changing mechanism to rotate one hundred and eighty degrees clockwise, thereby removing the circuit breaker from the pneumatic slide 102. During this process, the pneumatic slide 102 is controlled to reset to the right, and the active gear 902 drives the material changing shaft 201 in the right material changing mechanism to rotate one hundred and eighty degrees counterclockwise through the driven gear 903, thereby placing the circuit breaker on the reset pneumatic slide 102, and the cycle is carried out.

[0040] When the material changing shaft 201 in the left material changing mechanism rotates clockwise, the discharging gear 807 will first drive the second ratchet bar 806 to move away from the discharging pipe 805, and the second ratchet bar 806 will drive the discharging slide plate 802 and the discharging guide rod 8 to move synchronously, and the discharging spring 801 will be compressed. When the discharging slide plate 802 moves away from the discharging pipe 805, it will drive the discharging push plate 804 to slide to the left by a distance of a circuit breaker through the pull rod 803, thereby pushing the circuit breaker in the discharging pipe 805 to the left, and then the discharging gear 807 will be out of contact with the second ratchet bar 806, and the discharging spring 801 will be compressed. The spring 801 will push the discharge slide plate 802 to move towards the discharge pipe 805, thereby driving the discharge push plate 804 to reset to the right. After the material changing shaft 201 rotates one hundred and eighty degrees, the circuit breaker will be placed on the discharge pipe 805, and the placement position is located on the left side of the discharge push plate 804, so that the discharge push plate 804 can push the circuit breaker to the left again.
