Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] A marking fixture for a hose assembly line, combined with Figures 1 to 2 As shown, the device includes a chassis 1, with support legs 2 at the bottom. A turntable 4 that rotates vertically is mounted on the front panel of the chassis 1. The turntable 4 is equipped with a connector 3 and a marking mechanism 5. The connector 3 is used to insert a rubber tube. The connector 3 is coaxially mounted with the turntable 4 and is fixed in place. The turntable 4 rotates around the connector 3. The marking mechanism 5 is located on one side of the connector 3 and marks the outer wall of the rubber tube on the connector 3 as the turntable 4 rotates.

[0020] like Figure 3 As shown, the turntable 4 includes a cylindrical body 42 rotatably mounted on the front panel. The inner end of the cylindrical body 42, located within the housing 1, is connected to a rotary drive mechanism. The rotary drive mechanism includes a motor and a transmission assembly, both housed within the housing 1. The motor's rotation shaft is connected to the inner end of the cylindrical body 42 via the transmission assembly, driving the turntable 4 to rotate. Specifically, the transmission assembly is existing technology and can be any type of gear transmission assembly, belt transmission assembly, etc., without further limitation or description. A turntable body 41 is located at the outer end of the cylindrical body 42, situated on the outer side of the housing 1 and coaxially aligned with the cylindrical body 42.

[0021] A bearing is installed at the center of the turntable body 41 through a through hole. The outer ring of the bearing rotates while the inner ring is fixed. The outer ring of the bearing is connected to the turntable body 41, and a fixed shaft is fixedly installed on the inner ring of the bearing. The fixed shaft is perpendicular to the turntable body 41 and coaxial with it. The connector 3 is detachably installed on the outer end of the fixed shaft away from the housing 1 and is coaxial with the fixed shaft. This allows the connector 3 to be detachably installed on the turntable body 41 and coaxial with it, thus achieving a fixed installation of the connector 3. The turntable 4 can rotate with the connector 3 as the rotation center. At the same time, different connectors 3 can be replaced according to different hoses to achieve marking for different hoses.

[0022] The drawing mechanism 5 is disposed on the outer surface of the turntable body 41 away from the cylinder 42 and located on one side of the insertion seat 3. The drawing mechanism 5 includes a cylinder 51, which is disposed on the outer surface of the turntable body 41 away from the cylinder 42 along the radial direction of the turntable body 41. The telescopic rod of the cylinder 51 is disposed toward the insertion seat 3 and connected to a mounting base 53. A horizontally disposed drawing pen 54 is detachably disposed on the top of the mounting base 53. The pen tip of the drawing pen 54 is disposed toward the insertion seat 3. Driven by the cylinder 51, the drawing pen 54 moves away from and toward the rubber tube inserted on the insertion seat 3. When the drawing pen 54 comes into contact with the outer wall of the rubber tube, it completes the drawing as the turntable 4 rotates.

[0023] The turntable body 41 is provided with a limiting mechanism 6 on its outer surface, which is used to limit the position of the drawing pen 54. Specifically, the limiting mechanism 6 includes a vertical plate 61, which is detachably connected to the turntable body 41 and erected between the fixed shaft and the mounting base 53. A limiting bolt 62 is horizontally inserted in the vertical plate 61. The limiting bolt 62 is set perpendicular to the mounting base 53 and can be adjusted and fixed on the vertical plate 61 by a locking nut 63, so as to facilitate the adjustment of the position of the limiting bolt 62. The limiting bolt 62 is used to abut against the mounting base 53 when the drawing pen 54 is close to the rubber tube inserted on the plug-in 3 to achieve the limiting effect, thereby ensuring that the drawing pen 54 abuts against the outer wall of the rubber tube accurately.

[0024] The cylinder 51 is connected to an air pipe 52 via an air pipe connector. The other end of the air pipe 52 passes through a through hole 43 on the turntable body 41 and is connected to a pneumatic component in the cylinder 42. The pneumatic component is installed in the cylinder 42, thereby ensuring that the cylinder 51 can work normally without affecting the rotation of the turntable 4.

[0025] The front panel of the chassis 1 is equipped with a display screen 9, control buttons 10, an emergency stop button 7, and indicator lights 8. These are all located below the turntable 4. The display screen 9 displays working parameters; the control buttons 10 control the motor of the rotary drive mechanism; the emergency stop button 7 is used to stop the tooling in an emergency; and the indicator lights 8 indicate the working status of the tooling. A foot switch is located at the front of the chassis 1, and the foot switch controls the cylinder 51. The chassis 1 contains a PLC controller and a power supply circuit. The input terminals of the PLC controller are connected to the output terminals of the control buttons 10 and the foot switch. The output terminals of the PLC controller are respectively connected to the motor of the rotary drive mechanism, the pneumatic components of the drawing mechanism 5, and the controlled terminals of the indicator lights 8. The output terminals of the PLC controller are also connected to the input terminals of the display screen 9. The drawing control of the tooling is realized through the PLC controller. The power supply circuit is electrically connected to the PLC controller and is used to supply power to the tooling through an external power supply. The emergency stop button 7 is connected in series in the power supply circuit. In case of abnormality, pressing the emergency stop button 7 can instantly cut off the power supply to ensure safety.

[0026] When using this utility model, insert the rubber tube into the connector 3, press the control button 10, and the PLC controller controls the motor to drive the turntable 4 to rotate. Step on the foot switch, and the PLC controller controls the cylinder 51 to drive the drawing pen to abut against the outer wall of the rubber tube. At the same time, the turntable 4 continues to rotate, and the drawing pen completes the drawing.
