Description

Technical Field

[0001] The present application relates to the technical field of automated manufacturing, and in particular to a mechanical four-sided turntable position control device. Background Art

[0002] A turntable is a rotating table that is widely used in industrial production. Most of the existing turntables are two-sided turntables, that is, the turntable is fixed for -180° and 180° rotation. The turntable is equipped with an over-travel limit switch and a lever limit switch to ensure the turntable rotates accurately.

[0003] However, in the field of automobile manufacturing automated production lines, as flexible production is introduced with the continuous introduction of vehicle models, the two-sided turntable has to be changed to a four-sided turntable, that is, the turntable has been changed from the original fixed -180° and 180° rotation to -270°. 0 , -180 0 ,-90 0 ,90 0 , 180 0 ,270 0 However, after the change, the overtravel limit switch could not be installed due to the increase in working positions, and the lever limit switch could not be triggered due to the rotation angle, resulting in the four-sided turntable being unable to stop and constantly rotating, making it impossible to use normally. Utility Model Content

[0004] In order to ensure the normal rotation of a four-sided turntable, the present application provides a mechanical four-sided turntable position control device.

[0005] The present application provides a mechanical four-sided turntable position control device, which adopts the following technical solution:

[0006] A mechanical four-sided turntable position control device includes an encoder, an encoder connecting flange is fixedly connected to the encoder's rotating shaft, a connecting component for connecting the turntable rotating shaft is connected to the encoder connecting flange, and a fixing component for fixing the encoder is also provided on the encoder.

[0007] By adopting the above technical scheme, the encoder is connected to the turntable shaft of the four-sided turntable through the connecting component, and then the encoder is fixed on the turntable surface through the fixing component. When the turntable rotates, the connecting component will transmit the rotation of the turntable to the encoder connecting flange. The rotation of the encoder connecting flange will cause the encoder shaft to rotate, so that the encoder reads the rotation angle data, and then the encoder transmits the data to the external PLC device, which determines whether the rotation angle of the four-sided turntable is normal at this time. When the rotation angle is normal, the external PLC device will send a signal to control the four-sided turntable to work normally. When the rotation angle is abnormal, the external PLC device will send a signal to control the four-sided turntable to stop working and adjust it, and correct the rotation angle, thereby ensuring the normal rotation of the four-sided turntable.

[0008] Preferably, the connecting assembly includes a connecting clamp shaft and a connecting shaft connecting flange fixedly mounted on the connecting clamp shaft.

[0009] By adopting the above technical solution, through the setting of the connecting clamp shaft and the connecting shaft connecting flange, the connecting clamp shaft is used to connect the turntable shaft, and the connecting shaft connecting flange is used to connect the encoder connecting flange, thereby realizing the transmission of the rotation of the turntable shaft to the rotating shaft of the encoder, playing a transition role.

[0010] Preferably, the fixing assembly comprises a clamping seat detachably connected to the encoder, and a movable clamping jaw slidably connected to the clamping seat, and the movable clamping jaw is provided with a limiting member for limiting the position of the movable clamping jaw.

[0011] By adopting the above technical solution, through the setting of the clamping seat and the movable clamping claw, the clamping seat can be clamped and fixed on the encoder, and the movable clamping claw can slide on the clamping seat, so that the movable clamping claw can be moved to the table top of the four-sided turntable, so as to adapt to the installation position in different situations. After adjustment, it is limited by the limit piece and clamped on the table top of the four-sided turntable by the movable clamping claw, thereby realizing the positioning installation of the encoder.

[0012] Preferably, the card connector includes a first connection frame and a second connection frame detachably connected to the first connection frame.

[0013] By adopting the above technical solution and by setting the first connecting frame and the second connecting frame, when the first connecting frame is connected to the second connecting frame, the first connecting frame and the second connecting frame can fix the card connector by card connection, thereby realizing the connection of the card connector.

[0014] Preferably, the second connecting frame is connected to the first connecting frame by bolts.

[0015] By adopting the above technical solution, the second connecting frame is connected to the first connecting frame by bolts, which facilitates the installation of the first connecting frame and the second connecting frame.

[0016] Preferably, the movable clamping claw comprises a fixed claw slidably connected to the clamping seat and a movable claw slidably connected to the fixed claw, and an adjusting member for adjusting the position of the movable claw is provided between the fixed claw and the movable claw.

[0017] By adopting the above technical solution, through the setting of the fixed claw and the movable claw, the fixed claw and the movable claw are adjusted by the adjusting member to clamp on the table surface of the four-sided turntable, thereby realizing the connection between the movable clamping claw and the table surface of the four-sided turntable.

[0018] Preferably, the adjusting member is a threaded shaft rotatably connected to the fixed claw, and the threaded shaft is threadedly connected to the movable claw.

[0019] By adopting the above technical solution, when the position of the moving claw needs to be adjusted, the user can rotate the threaded shaft, and the rotation of the threaded shaft will cause the moving claw to slide on the fixed claw, thereby achieving the adjustment of the position of the moving claw.

[0020] Preferably, the limiting member is an abutment bolt threadedly connected to the fixing claw, and the abutment bolt can pass through the fixing claw and abut on the clamping seat.

[0021] By adopting the above technical solution and setting the abutment bolt, when it is necessary to limit the movement of the fixing claw, the user can rotate the abutment bolt so that the abutment bolt abuts against the clamping seat to abut and fix the fixing claw.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. Through the setting of encoder, encoder connecting flange and connecting components, the encoder is used to monitor the rotation of the four-sided turntable in real time, and send signals to the external PLC device, and the rotation of the four-sided turntable is controlled in real time through the external PLC device. When an abnormality occurs, the rotation of the four-sided turntable can be corrected in time to ensure that the four-sided turntable can rotate normally;

[0024] 2. Through the setting of the clamping seat, the movable clamping claw and the abutment bolt, the encoder is connected to the table top of the four-sided turntable, and can be adapted to different installation positions for easy use. BRIEF DESCRIPTION OF THE DRAWINGS
