Description

Technical Field

[0001] The utility model relates to the technical field of circuit breakers, in particular to an insertion type mounting fixture for a molded case circuit breaker. Background Art

[0002] The insertion type molded case circuit breaker is an electrical protection device, mainly used for sectional protection and control of circuits. It is installed by directly inserting the circuit breaker into the guide rail and is widely used in circuit protection and control in places such as residential buildings, commercial buildings, and industrial factories.

[0003] For the existing circuit breaker mounting fixture, such as the circuit breaker assembly jig disclosed in the utility model patent with the application number 202321639633.8, its main structure includes a bracket. The bracket is provided with a fixed seat and a movable seat. The fixed seat is provided with a first clamping assembly, and the movable seat is provided with a second clamping assembly that cooperates with the first clamping assembly to clamp the circuit breaker housing. The movable seat can move relative to the fixed seat to adapt to circuit breaker housings of different sizes; during use, since the movable seat can move relative to the fixed seat, the distance between the first clamping assembly and the second clamping assembly can be adjusted, so that the first clamping assembly and the second clamping assembly can adapt to and clamp circuit breaker housings of different sizes. The movable seat is provided with a knob that can lock or unlock the movable seat. When the knob is unlocked, the slider can slide on the slide rail. Two positioning plates are used to position and clamp the circuit breaker housing. The rotating shaft can rotate along the bearing seat so that the circuit breaker housing can rotate, so that the circuit breaker housing faces upward at different angles to facilitate the installation of components inside the circuit breaker housing. The first part fixes the circuit breaker housing through a bolt structure, and the second part is fixedly connected to the connecting plate through bolts. The first clamping assembly is connected with a driving assembly that can drive the rotating shaft to rotate.

[0004] However, for the existing mounting fixture, the staff needs to fix the two parts of the parts on the fixture respectively, and the work efficiency is relatively low. Moreover, most of the existing mounting fixtures cannot detect the installation effect, and it is very easy to have the situation of incomplete insertion. Summary of the Utility Model

[0005] To solve the above technical problems, the utility model provides an insertion type mounting fixture for a molded case circuit breaker that not only saves the labor for fixing and positioning the circuit breaker, improves the work efficiency, but also can detect the insertion effect of the circuit breaker, detect whether the insertion is in place, and drive the circuit breaker after installation to unload the material.

[0006] An insertion mounting fixture for a plastic case circuit breaker of the utility model comprises a support mechanism; further comprising a discharging mechanism, a rotating mechanism, a moving mechanism, a grasping mechanism and a guiding mechanism. The discharging mechanism is installed on the support mechanism and discharges the assembled circuit breaker. The rotating mechanism is installed on the support mechanism and drives the circuit breaker to move onto the base. The moving mechanism is installed on the rotating mechanism and adjusts the alignment of the circuit breaker and the base. The grasping mechanism is installed on the moving mechanism and clamps and fixes the circuit breaker. The guiding mechanism is installed on the support mechanism and guides and supports the base. The base is conveyed on the support mechanism and is blocked at a designated position by the guiding mechanism. The staff places the assembled circuit breaker in the discharging mechanism. The discharging mechanism discharges it neatly. The grasping mechanism clamps and fixes the base. Then the rotating mechanism drives the grasping mechanism and the circuit breaker to move above the base. The moving mechanism detects it to align the base and the circuit breaker. The grasping mechanism inserts the circuit breaker into the base and then drives the base and the circuit breaker to move together to detect the insertion effect.

[0007] Preferably, the support mechanism comprises a workbench, two groups of conveying rollers, a conveyor belt, a soft pad and a support frame. The bottom end of the workbench is connected to the ground. The two groups of conveying rollers are rotatably installed on the workbench. The conveyor belt is tensioned and installed on the two groups of conveying rollers. The soft pad is laid on the top end of the workbench. The bottom end of the support frame is connected to the top end of the workbench. The two groups of conveying rollers rotate to drive the conveyor belt to rotate. The base is conveyed forward on the conveyor belt, which is convenient for inserting the circuit breaker into the base. After the insertion is completed, the grasping mechanism moves the base and the circuit breaker onto the soft pad for temporary placement, which is convenient for the staff to package them.

[0008] Preferably, the discharging mechanism comprises a fixing plate, a rotating shaft, a pushing plate, a cylinder 1 and a connecting seat. The bottom end of the fixing plate is connected to the top end of the workbench. The rotating shaft is rotatably installed on the fixing plate. The pushing plate is installed on the rotating shaft. The cylinder 1 is installed on the workbench. The connecting seat is installed on the pushing plate and is rotatably connected to the cylinder 1. The staff places the assembled circuit breaker on the workbench. When the grasping mechanism takes away a circuit breaker, the cylinder 1 pushes the connecting seat and the pushing plate to rotate so that one side of the circuit breaker is close to the fixing plate, which is convenient for the grasping mechanism to grasp it.

[0009] Preferably, the rotating mechanism includes a servo motor, a first reducer, a transmission shaft, a cross beam and rib plates. The servo motor is installed on the workbench, and the first reducer is installed on the workbench. The transmission shaft is rotatably installed between the workbench and the support frame and is longitudinally connected to the first reducer. The cross beam is installed on the transmission shaft, and the rib plates are connected and installed between the transmission shaft and the cross beam. Through holes are provided on the cross beam and the rib plates. After the grasping mechanism grasps the circuit breaker, the servo motor is started. The servo motor drives the transmission shaft to rotate through the first reducer. The transmission shaft drives the cross beam and the rib plates to rotate 90°. After the circuit breaker is installed on the base, the transmission shaft continues to drive the cross beam and the rib plates to rotate 90°. The base and the circuit breaker are placed on the soft pad. Then the servo motor drives the transmission shaft to rotate in the reverse direction to reset. By setting the rib plates, the stability of the cross beam is enhanced.

[0010] Preferably, the moving mechanism includes two groups of sensors, a motor, a second reducer, a reciprocating lead screw and a slider. The two groups of sensors are both installed on the support frame and are respectively located directly above the discharging mechanism and the guiding mechanism. The motor is installed on the cross beam, and the second reducer is installed on the cross beam. The reciprocating lead screw is rotatably installed in the through hole of the cross beam, and the slider is slidably installed on the reciprocating lead screw. The motor is started. The motor drives the reciprocating lead screw to rotate through the second reducer. The reciprocating lead screw drives the slider to move back and forth. When the sensor detects that the circuit breaker coincides with the slider, it stops, which is convenient for the grasping mechanism to grasp the circuit breaker. Similarly, when the circuit breaker moves onto the base, when the sensor detects that the circuit breaker coincides with the base, it stops, which is convenient for inserting the circuit breaker into the base.

[0011] Preferably, the grasping mechanism includes a second cylinder, a connecting frame, an electric cylinder and a clamping plate. The top end of the second cylinder is connected to the bottom end of the slider, and the top end of the connecting frame is connected to the bottom end of the second cylinder. A sliding groove is provided on the connecting frame. The electric cylinder is installed on the connecting frame, and the clamping plate is slidably installed in the sliding groove of the connecting frame and is connected to the top end of the electric cylinder. After it is detected that the slider coincides with the circuit breaker, the second cylinder pushes the connecting frame to descend. One side of the connecting frame contacts the fixed plate. The circuit breaker is located between the second cylinder and the clamping plate. The electric cylinder is started to push the clamping plate to slide, so that the clamping plate and the connecting frame cooperate to clamp the circuit breaker. Then the second cylinder contracts to drive the connecting frame to rise. Similarly, when the sensor detects that the circuit breaker coincides with the base, the second cylinder pushes the connecting frame and the circuit breaker to descend, inserts the circuit breaker into the base, and then the second cylinder contracts to drive the circuit breaker and the base to rise together. When the insertion is locked, the base rises and moves with the circuit breaker. When the insertion is not in place, the base remains on the conveyor belt, and the grasping mechanism drives the circuit breaker to unload, and the staff reinspects the circuit breaker.

[0012] Preferably, the guiding mechanism includes a baffle plate, two groups of guiding plates, two groups of hydraulic cylinders and a bottom plate. The baffle plate is installed on the workbench, the two groups of guiding plates are both installed on the baffle plate, the two groups of hydraulic cylinders are both installed on the workbench, and the bottom end of the bottom plate is connected to the top ends of the two groups of hydraulic cylinders; by arranging the two groups of guiding plates, the bases conveyed on the conveyor belt are made to move closer to the middle and are both within the moving range of the slider. By arranging the baffle plate to block the bases, one side of the base is made to closely adhere to the baffle plate for convenient positioning. When the grasping mechanism drives the circuit breaker to press down and insert into the base, the two groups of hydraulic cylinders push the bottom plate to lift the conveyor belt, preventing the base from squeezing the conveyor belt downward and causing the situation of incomplete insertion.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: The base is conveyed on the supporting mechanism and is blocked at the designated position by the guiding mechanism. The staff places the assembled circuit breaker in the discharging mechanism, and the discharging mechanism arranges it neatly. The grasping mechanism clamps and fixes the base, and then the rotating mechanism drives the grasping mechanism and the circuit breaker to move above the base. The moving mechanism detects it to align the base and the circuit breaker. The grasping mechanism inserts the circuit breaker into the base and then drives the base and the circuit breaker to move together, thereby detecting the insertion effect.
