[0002] The base of molded case circuit breakers is mostly made of insulating materials (such as plastic, rubber or reinforced BMC material). It is a key component of the circuit breaker, carrying the entire circuit breaker and fixedly installed on the circuit board. At the same time, it provides a conductive connecting piece to connect with the conductive line on the circuit board. Because the base of the molded case circuit breaker needs to be screwed during the production and processing, the automatic screw locking device of the molded case circuit breaker base becomes one of the indispensable equipment in its production and processing.

[0003] In the prior art, the automatic screw locking device of the molded case circuit breaker base is mostly driven by multiple driving devices. For example, the movement of the molded case circuit breaker base requires the use of a driving device, and the movement of the screw locking mechanism also requires the use of a driving device. As a result, the automatic screw locking device of the molded case circuit breaker base needs to use too many driving devices during operation, thereby consuming too much energy. The large energy consumption also leads to an increase in the production cost of the molded case circuit breaker base, thereby reducing the market competitiveness of the product.

[0041] One side of the outer wall of the expansion plate 43 is rotatably connected with the second threaded rod 47 and the third threaded rod 48 through the sixth square plate; one end of the outer wall of the second threaded rod 47 and the third threaded rod 48 passes through the first movable plate 44 and the second movable plate 45 respectively; the second threaded rod 47 and the third threaded rod 48 are threadedly connected with the first movable plate 44 and the second movable plate 45 respectively; a circular through groove 49 is provided on one side of the outer wall of the first movable plate 44, and the circular through groove 49 matches the third threaded rod 48; the outer side walls of the second threaded rod 47 and the third threaded rod 48 are fixedly connected with the eighth gear 50 and the ninth gear 51 respectively, and the radius of the ninth gear 51 is half of the eighth gear 50; the eighth gear 50 and the ninth gear 51 are meshed with each other, and by rotating the second threaded rod 47, due to the outer sides of the second threaded rod 47 and the third threaded rod 48 The walls are respectively fixed with an eighth gear 50 and a ninth gear 51, and the radius of the ninth gear 51 is half of the eighth gear 50, and the eighth gear 50 and the ninth gear 51 are meshed with each other, so that the rotation of the second threaded rod 47 drives the ninth gear 51 to rotate through the eighth gear 50, and the ninth gear 51 drives the third threaded rod 48 to rotate, so that the second threaded rod 47 and the third threaded rod 48 rotate at the same time, and because the radius of the ninth gear 51 is half of the eighth gear 50, the moving distance of the first movable plate 44 is always twice that of the second movable plate 45, so that the distance between a pair of third locking screw devices 46 and the first locking screw device 8 is always equal, so that the device can adjust the position of a pair of third locking screw devices 46 according to the situation of the molded case circuit breaker base, making the device more flexible and convenient.

[0042] When the present invention is in use, by placing the molded case circuit breaker base on the conveyor belt 4, the hydraulic cylinder 6 drives the sliding plate 7 to move, and the movement of the sliding plate 7 drives the first rack 10 to move, so that the first rack 10 drives the connecting device and the first bevel gear 11 to rotate. Because the first bevel gear and the second bevel gear 14 are meshed with each other, the first bevel gear 11 drives the second bevel gear 14 and the rotating rod 13 to rotate, and the rotating rod 13 drives the first roller 2 to rotate, thereby driving the conveyor belt 4 and the molded case circuit breaker base to move, so that the molded case circuit breaker base moves to the first screw locking device 8. At this time, the sliding plate 7 will also move the first screw locking device 8 to a suitable position, so that the first screw locking device 8 performs a screw locking operation on the molded case circuit breaker base, so that the device completes the molding through a motor. The movement of the shell circuit breaker base and the movement of the first locking screw device 8 not only save a driving device, but also save energy efficiency, reduce costs, and improve market competitiveness. When the sliding plate 7 drives the first rack 10 to move forward, the third gear 17 is meshed with the first rack 10, so that the movement of the first rack 10 drives the second rotating rod 16 to rotate through the third gear 17, so that the second rotating rod 16 drives the connecting plate 18 to rotate, and the connecting plate 18 drives the second arc block 21 to rotate, so that the plane of the second arc block 21 contacts the plane of the first arc block 19, thereby driving the first arc block 19 and the circular plate 12 to rotate, so that the circular plate 12 drives the first rotating rod 15 and the first bevel gear 11 to rotate, so that the first bevel gear 11 is driven by the second bevel gear 14. The movable rotating rod 13 and the first rotating roller 2 rotate to move the conveyor belt 4 and the molded case circuit breaker base, and when the molded case circuit breaker base moves, the sliding plate 7 and the first screw locking device 8 will also move forward, so that the first screw locking device 8 moves to a suitable position to lock the screws on the molded case circuit breaker base. When one of the targets on the molded case circuit breaker base is completed, the sliding plate 7 moves backward. At this time, the connecting plate is reversed, and the arc surface of the second arc block 21 encounters the arc surface of the first arc block 19. At this time, the second arc block 21 will shrink, so that the circular disk 12 and the first rotating rod 15 do not rotate, and the conveyor belt 4 does not move. When the sliding plate 7 moves to a suitable position, it moves forward again, driving the molded case circuit breaker base to move, and then the first screw locking device 8 continues to lock the screws. By analogy, the moving distance of the conveyor belt 4 can be adjusted by the moving distance of the sliding plate 7, so that the device can fully automatically complete the screw locking operation of the molded case circuit breaker base, and the movement of the sliding plate 7 can be adjusted according to the distance of the screws required to be locked on the molded case circuit breaker base, making the device more intelligent and practical. When the connecting disk 18 drives the circular disk 12 to rotate, the first arc block 19 on the circular disk 12 will encounter the arc side of the limit block 42. At this time, the limit block 42 will drive the circular rod 41 and the fifth spring to contract, so that the circular disk 12 and the first rotating rod 15 can rotate normally. When the connecting disk 18 reverses and does not drive the circular disk 12 to rotate, the plane of the first arc block 19 on the circular disk 12 will contact the inclined surface on the limit block 42. At this time,The first arc block 19 is resisted, so that the circular disk 12 will not rotate, so that the circular disk 12 can rotate only when the device needs the circular disk 12 to rotate, and if it does not need it, the circular disk 12 will not rotate, making the device more accurate and intelligent, and when the sliding plate 7 moves forward to prepare for the screw locking operation on the molded case circuit breaker base, the sliding plate 7 moves to drive the square shell 32 to move, so that the square shell 32 drives the adjustment plate 33 and the second spring and the clamping plate 34 to move, and when the square shell 32 moves to a certain position, the clamping plate 34 will encounter the molded case circuit breaker base, and at this time the clamping plate 34 and the fixing block 31 will clamp and fix the molded case circuit breaker base, and at this time the first screw locking device 8 will be more accurate and stable when performing the screw locking operation, so that the first screw locking device 8 can be The screw locking operation is not prone to error, and the error rate is reduced. By rotating the first threaded rod 36, since the first threaded rod 36 is threadedly connected to the adjustment plate 33, the rotation of the first threaded rod 36 drives the adjustment plate 33 to move, and the adjustment plate 33 drives the second spring and the clamping plate 34 to move, so that the device can adjust the position of the adjustment plate 33 by rotating the first threaded rod 36, so that the device can adjust the clamping force of the clamping plate 34 according to the situation of the molded case circuit breaker base, so that the clamping force of the clamping plate 34 is moderate, so that the molded case circuit breaker base can be clamped and fixed more stably, and when the sliding plate 7 moves, the movement of the sliding plate 7 will drive the square plate 23 to move through the connecting rod 24, so that the square plate 23 drives the second screw locking device 25 to move. The device can simultaneously perform screw locking operations on the top and middle of the molded case circuit breaker base, thereby further improving the efficiency of screw locking operations on the molded case circuit breaker base. When the sliding plate 7 moves forward to prepare for screw locking on the middle of the molded case circuit breaker base, the sliding plate 7 moves to drive the connecting rod 24 and the second rack 26 to move. Since the fourth gear 28 is meshed with the second rack 26, the movement of the second gear drives the fourth gear 28 to move, and the fourth gear 28 drives the third rotating rod 27 and the fifth gear 29 to rotate. Since the gear groove 30 is meshed with the fifth gear 29, the rotation of the fifth gear 29 drives the square plate 23 to move upward through the gear groove 30. Similarly, when the first screw locking device 8 completes the screw locking operation, the sliding plate 7 moves backward. At this time, the placing plate 5 and the second screw locking device 25 move downward, so that the second screw locking device 25 can perform a screw locking operation on the top of the molded case circuit breaker base, and the position of the molded case circuit breaker base can be adjusted by moving the sliding plate 7, so that the second screw locking device 25 can perform a screw locking operation on the molded case circuit breaker base more conveniently and more accurately, so that the device first performs a screw locking operation on the middle part of the molded case circuit breaker base, and then performs a screw locking operation on the top of the molded case circuit breaker base, and the two operations are completed alternately without wasting time, making the device more intelligent, convenient, practical, and more efficient, and more conveniently and quickly completing the screw locking operation of the molded case circuit breaker base, and when the square plate 23 moves downward, so that the second screw locking device 25 performs a screw locking operation,The downward movement of the square plate 23 drives the fixing plate 37, the third spring and the extrusion block 38 to move downward, so that the extrusion block 38 is squeezed above the base of the molded case circuit breaker, so that the second screw locking device 25 is more stable when performing the screw locking operation, and the third spring is not prone to failure through the limiting of the guide rod 39, and the extrusion block 38 is not easy to shift or shake when being squeezed and fixed, and the first movable plate 44 and the second movable plate 45 are slidably connected to one side of the outer wall of the expansion plate 43; the third screw locking device 46 is fixedly connected to one side of the outer wall of the first movable plate 44 and the second movable plate 45, so that when the first screw locking device 8 is screwed, a pair of third screw locking devices 46 will also perform the screw locking operation at the same time, so that the device can perform multiple screw locking operations on the base of the molded case circuit breaker at one time, thereby effectively improving the screw locking efficiency of the device, making the device more efficient, and by rotating The second threaded rod 47 is moved. Since the outer side walls of the second threaded rod 47 and the third threaded rod 48 are respectively fixed with the eighth gear 50 and the ninth gear 51, and the radius of the ninth gear 51 is half of the eighth gear 50, and the eighth gear 50 and the ninth gear 51 are meshed with each other, the rotation of the second threaded rod 47 drives the ninth gear 51 to rotate through the eighth gear 50, and the ninth gear 51 drives the third threaded rod 48 to rotate, so that the second threaded rod 47 and the third threaded rod 48 rotate at the same time, and since the radius of the ninth gear 51 is half of the eighth gear 50, the moving distance of the first moving plate 44 is always twice that of the second moving plate 45, so that the distance between the pair of third locking screw devices 46 and the first locking screw device 8 is always equal, so that the device can adjust the position of the pair of third locking screw devices 46 according to the situation of the molded case circuit breaker base, making the device more flexible and convenient.
