Description

Technical Field

[0001] The present invention relates to an automatic production device for motors, and particularly to a rotor blanking and turning mechanism. Background Art

[0002] To improve production efficiency and reduce labor costs, automatic production devices are usually used for the assembly and loading / unloading of components. The iron core and the rotating shaft are generally vertically press-fitted. After the assembly of the iron core and the rotating shaft is completed, a 90° turn of the rotor is achieved through a jaw mechanism and a rotating cylinder, turning the vertical rotor into a horizontal rotor, so as to facilitate the subsequent placement of the rotor into a storage box. The use of the jaw mechanism and the rotating cylinder will increase the equipment cost, and the rotor has to pause when being clamped or released by the jaws, which will also prolong the production time. Summary of the Invention

[0003] The purpose of the present invention is to provide a rotor blanking and turning mechanism with lower cost and smoother turning of the rotor so as to shorten the production time.

[0004] To achieve the above purpose, the present invention adopts the following technical solutions: A rotor blanking and turning mechanism includes a first conveying track and a second conveying track arranged along the front-back direction. The second conveying track gradually extends downward from the rear to the front. The first conveying track has a first through slot with an upward opening for the rotating shaft of the rotor to pass through. The second conveying track has a second through slot with an upward opening for making way for the iron core of the rotor. The first conveying track has a first supporting surface for supporting the iron core of the rotor. The second conveying track has a second supporting surface for supporting the rotating shaft of the rotor. On the left and right sides of the front end of the first conveying track, a first guiding member and the second conveying track are respectively provided. Both the second supporting surface and the rear end of the second through slot are located on the left or right side of the front end of the first through slot. One side of the first guiding member close to the second conveying track has a first guiding surface for contacting the iron core of the rotor. The first guiding surface gradually extends towards the second conveying track side from the rear to the front, and the lower end surface of the first guiding member is located above the second supporting surface.

[0005] When the rotor just disengages from the first conveying track, the outer wall of the iron core of the rotor will contact the first guiding surface. Subsequently, the rotor completely disengages from the first conveying track, and the end of the rotor with the iron core will flip under the action of gravity. Due to the setting of the first guiding surface, the iron core will flip away from the first guiding surface side, that is, towards the second conveying track side, and the iron core will flip into the second passing slot of the second conveying track to achieve the flipping of the rotor. Among them, the second supporting surface of the second conveying track supports the rotating shaft of the rotor; the slot wall of the second passing slot limits the iron core to prevent the rotor from rotating, and the lower end surface of the guiding member limits the rotor to prevent the rotor from jumping. The present invention can achieve the flipping of the rotor from vertical to horizontal, and does not require an external driving mechanism, which can reduce the equipment cost; the rotor does not pause during flipping, and the flipping of the rotor is smoother; when the previous rotor is flipping, the next rotor can start the flipping action, which can save the flipping time and improve the production efficiency.

[0006] Preferably, the rear end of the second supporting surface is connected to the front end of the first supporting surface. The above setting makes the movement of the rotor smoother.

[0007] Preferably, a second guiding member is provided at the side wall of the second conveying track close to the first guiding member. The second guiding member has a second guiding surface for contacting the rotating shaft of the rotor. The second guiding surface gradually extends away from the second conveying track side from the rear to the front. The upper end surface of the second guiding member is located below the lower end surface of the first guiding member. The second guiding member is used to guide the lower end of the rotating shaft of the rotor so that the iron core of the rotor can better flip towards the second passing slot side.

[0008] Preferably, the upper end surface of the second guiding member gradually extends downward from the rear to the front. The above setting is for the accommodation of the iron core of the rotor, so that the iron core of the rotor will not hit the second guiding member after flipping.

[0009] Preferably, the upper end surface of the second guiding member is located below the second supporting surface, or the upper end surface of the second guiding member is at the same height as the second supporting surface. The second supporting surface supports the rotating shaft of the rotor. The above setting of the upper end surface of the second guiding member can prevent the rotor from tilting, so as to prevent the rotor from flipping when the width of the second passing slot is greater than the axial length of the iron core.

[0010] Preferably, the rear end of the first guiding member extends backward to be located above the first supporting surface, so that the rear end of the first guiding surface is located above the first conveying track. When the rotor moves to the front end of the first conveying track, the outer wall of the iron core of the rotor contacts the first guiding surface. The rotor is limited by the guiding surface before flipping, so that the flipping direction accuracy of the iron core of the rotor is higher, to ensure the flipping effect of the rotor and reduce the possibility of the iron core of the rotor hitting the second supporting surface of the second conveying track.

[0011] Preferably, the rear end of one side wall of the second conveying track is connected to the front end of the side wall of the first through groove of the first conveying track. When the rotating shaft of the rotor just disengages from the first through groove of the first conveying track, the rotating shaft of the rotor will contact the side wall of the second conveying track, so that the iron core of the rotor can only flip towards the second conveying track side; at the same time, when the rotor flips, the rotating shaft of the rotor will contact the second supporting surface of the second conveying track and the top end of the side wall of the second conveying track to provide a fulcrum when the rotor flips, so as to avoid the situation where the iron core of the rotor opens on the second supporting surface, and to ensure that the iron core of the rotor can flip into the second through groove.

[0012] Preferably, a positioning hole penetrating downward is provided at the rear end of the first guiding member. The positioning hole is arranged in the front-rear direction and is arc-shaped or straight-shaped. The first guiding member is fixed to the first conveying track by fastening screws, and the fastening screws pass through the positioning hole. The first guiding member can rotate left and right around the fastening screws to adjust the angle of the guiding surface, so that the rotor can flip from a vertical state to a horizontal state.

[0013] Preferably, the first guiding member is provided with two positioning holes, and the two positioning holes are symmetrically arranged left and right. The above setting improves the fixing stability of the guiding member.

[0014] Preferably, the second conveying track includes two parallel side plates, one side plate is a fixed plate, and the other side plate is a movable plate. The side plates are both arranged on the bottom plate. A guiding seat is provided on the bottom plate, and a guiding rod arranged in the left-right direction is fixed on the guiding seat. The guiding rod is fixed to the fixed plate, and the movable plate is provided with a guiding hole corresponding to the guiding rod. A fixing seat is further provided on the bottom plate, and an adjusting rod is rotatably fixed on the fixing seat. The movable plate is provided with an adjusting hole corresponding to the adjusting rod. After the adjusting rod passes through the adjusting hole, it is fixed to the fixed plate. A threaded structure that cooperates with each other is provided on the inner wall of the adjusting hole and the outer wall of the adjusting rod. The above setting realizes the adjustment of the width between the movable plate and the fixed plate, so that the mechanism of the present invention can be used for the flipping of rotors with different iron core lengths. Among them, the adjusting rod can adopt a multi-head screw rod, and the self-locking property of the multi-head screw rod itself is used to realize the positioning of the movable plate.
