[0023] The utility model discloses an auxiliary positioning device for a workpiece bending machine, comprising:

[0024] The processing platform 1 is used to place the workpiece to be processed, and the processing platform 1 is provided with a scale groove 121 for marking the angle, and the scale groove 121 is semicircular;

[0025] The positioning rod 2 is rotatably arranged on the top surface of the processing platform 1, and the rotation center of the positioning rod 2 coincides with the center of the semicircular scale groove 121. The workpiece abuts against one side of the positioning rod 2. The end of the positioning rod 2 close to the bending mold 6 is also provided with a pointer 21 for indicating an angle.

[0026] The transmission component 3 is arranged in the processing platform 1, and one end of the transmission component 3 is connected to the positioning rod 2. The transmission component 3 is used to drive the positioning rod 2 to rotate a corresponding angle.

[0027] In the specific implementation, the staff adjusts the positioning rod 2 to the inclination angle at which the workpiece to be processed needs to be bent through the transmission component 3. After the positioning rod 2 is adjusted, the worker manually abuts the workpiece to be processed against one side of the positioning rod 2, and puts the end that needs to be bent into the bending mold 6 and abuts against the blocking block 7 to perform the bending operation.

[0028] In the utility model, the rotation of the positioning rod 2 is controlled by the transmission component 3, and the cooperation between the positioning rod 2 and the scale groove 121 can know the rotation angle of the positioning rod 2 in real time. When one side of the workpiece abuts the positioning rod 2, the rotation angle of the workpiece and the positioning rod 2 are consistent, so that the rotation angle of the positioning rod 2 can be accurately controlled, and the processing error can be reduced even in mass production.

[0029] In one embodiment, the transmission component 3 includes a first power unit 31 arranged in the processing platform 1, and a rotating rod 32 is vertically provided on the output shaft of the first power unit 31. The end of the rotating rod 32 away from the first power unit 31 passes through the top surface of the processing platform 1 and is connected to the positioning rod 2. When the positioning rod 2 needs to be rotated, the first power unit 31 drives the positioning rod 2 to rotate through the rotating rod 32. A first control element (not shown in the figure) is also provided on the first power unit 31, and the first control element is connected to the first power unit 31 by signal, so as to control the rotation speed and rotation angle of the first power unit 31.

[0030] With this design, when the workpiece needs to be bent, the required parameters for bending the corresponding workpiece are first retrieved from the first control element, and then the first power unit 31 is started. The first power unit 31 drives the rotating rod 32 to rotate so that the positioning rod 2 is rotated on the processing platform 1 to the angle required for processing the corresponding workpiece.

[0031] Preferably, the first power unit 31 may adopt a servo motor in the prior art.

[0032] Preferably, the first control element may adopt a PLC control unit in the prior art.

[0033] In one embodiment, the processing platform 1 includes a base 11, the cross-section of the base 11 is "L"-shaped, and a movable platform 12 is slidably provided on the top surface of the long side portion of the base 11 along the installation direction of the bending mold 6. The above-mentioned transmission component 3 is arranged in the mobile platform 12, and the above-mentioned positioning rod 2 and the scale groove 121 are both arranged on the top surface of the mobile platform 12. A driving component 4 is provided in the base 11 for driving the mobile platform 12 to move back and forth on the base 11 along the setting direction of the bending mold 6.

[0034] With this design, when the inclination angle required for bending the workpiece is large, it is difficult for the workpiece to abut against the appropriate position of the stop block 7. At this time, the driving component 4 is controlled to drive the workpiece to move back and forth on the base 11 along the setting direction of the bending mold 6 through the mobile platform 12 until the workpiece abuts against the appropriate position of the stop block 7.

[0035] In one embodiment, a slide groove 111 is provided on the top surface of the long side of the base 11 along the installation direction of the bending mold 6, and the bottom end of the movable platform 12 is slidably disposed in the slide groove 111;

[0036] The driving component 4 includes a lead screw 41 that is rotatably inserted into the slide groove 111. The lead screw 41 is arranged along the opening direction of the slide groove 111 and one end of the lead screw 41 passes through the bottom end of the mobile platform 12 and extends out of the base 11. A second power unit 42 is provided at the extended end of the lead screw 41. When the mobile platform 12 moves, the second power unit 42 drives the mobile platform 12 to reciprocate on the top surface of the base 11 through the lead screw 41. A second control element (not shown in the figure) is also provided on the second power unit 42. The second control element is connected to the second power unit 42 by signal and is used to control the rotation speed of the second power unit 42.

[0037] With this design, when the workpiece needs to be bent, the required parameters for the movement of the mobile platform 12 during the processing of the corresponding workpiece are first retrieved from the second control element, and the lead screw 41 is driven to rotate by the second power unit 42, thereby driving the mobile platform 12 to move to a position pre-set by the second control element, and the second control element cooperates with the first control element, and each control element sends a signal to the corresponding power unit to make the positioning rod 2 and the mobile platform 12 move simultaneously to the corresponding position when the workpiece is bent. Each control element can store data for processing a variety of workpieces, so that it can be suitable for different types of workpieces and improve work efficiency.

[0038] Preferably, the second power unit 42 can adopt a servo motor in the prior art.

[0039] Preferably, the second control element may adopt a PLC control unit in the prior art.

[0040] In one embodiment, the height of the short side of the base 11 is flush with the top surface of the moving platform 12, and a notch 112 is provided at the top of the short side of the base 11;

[0041] The base 11 is also provided with a protective component 5, which includes a winding rod 51 rotatably set in the short side of the base 11, and a protective cloth 52 is rolled up on the winding rod 51. The head end of the protective cloth 52 is connected to one end of the moving platform 12 close to the short side of the base 11. When the moving platform 12 moves in the direction away from the short side of the base 11, the moving platform 12 drives the protective cloth 52 to be pulled out from the groove 112 and cover the space between the moving platform 12 and the short side of the base 11. A torsion spring (not shown in the figure) is also provided in the winding rod 51, which is used to drive the winding rod 51 to rotate in the direction of the second power unit 42.

[0042] With such a design, when the mobile platform 12 moves in the direction of the short side away from the base 11, the mobile platform 12 drives the protective cloth 52 to be pulled out from the slot 112 and cover the space between the short sides of the mobile platform 12 and the base 11, so as to prevent external impurities from falling between the mobile platform 12 and the base 11 and interfering with the resetting of the mobile platform 12. As the protective cloth 52 is pulled out, the roller rotates in the direction away from the second power unit 42, and the torsion spring is compressed. When the work is completed, the mobile platform 12 is reset, and the torsion spring is reset and drives the roller to rotate in the direction of the second power unit 42 and reel up the protective cloth 52.
