Description

Technical Field

[0001] The utility model relates to the technical field of bending machine detection, in particular to a special angle detection transmission device for bending machines. Background Art

[0002] After the bending process of the bending machine is completed, the measured angle needs to be checked manually. If there is a deviation between the actual bending angle and the theoretical value, it is necessary to manually modify the compensation coefficient in the CNC system and re-bend, which is inefficient, has a low bending yield and low economic efficiency.

[0003] Traditional bending machines have the following disadvantages when bending: 1) The bending compensation coefficient of the bending machine requires manual trial bending and manual detection of the angle to be input into the system for calculation, which is inefficient and wastes plate materials; 2) Due to the different bending lengths, plate thicknesses, and materials of the workpiece, the compensation coefficients are also different and cannot be corrected in real time; 3) Some existing bending machines with angle detection devices are generally installed on the lower beam of the bending machine. When the lower beam of the bending machine is equipped with hydraulic compensation, the lower beam is lifted by the action of the oil cylinder to cause the lower beam to undergo elastic deformation of the upward arch, which will cause the running guide rail of the angle detection to also undergo upward arch deformation, resulting in a large measurement accuracy error. Utility Model Content

[0033] effect:

[0034] The right side fixed bracket 1 and the left side fixed bracket 2 are installed on both sides of the bending machine. At the same time, the right side fixed bracket 1 and the left side fixed bracket 2 are connected and fixed to two rectangular aluminum profiles 3. They constitute the main supporting components of the angle detection device. The outer surface of the two rectangular aluminum profiles 3 is installed with a linear guide 4 to provide guidance for the left and right movement of the entire angle detection sensor. Since the entire guide rail is directly installed on the lower beam of the bending machine, the guide rail will not be deformed due to the deformation of the lower beam during bending, thereby affecting the detection accuracy.

[0035] The right fixing bracket 1 and the left fixing bracket 2 are both made of square tubes and steel plates welded and precisely processed, which effectively ensures the parallelism of the two aluminum profiles after installation.

[0036] The rectangular aluminum profile 3 is a standard finished extruded aluminum profile with high straightness. As the installation reference surface of the linear guide 4, it eliminates the need for processing and saves materials. At the same time, due to its own characteristics, the aluminum profile is light in weight, which reduces the load on the right fixed bracket 1 and the left fixed bracket 2, ensures the stability of the structure, and is not easy to deform.

[0037] The limit blocks 5 are installed at the left and right ends of the rectangular aluminum profile 3 to prevent the entire angle detection sensor mechanism from rushing out of the guide rail and damaging the angle detection sensor 17 after the limit sensor 19 fails, thereby ensuring its safety.

[0038] The aluminum profile end cover plates 6 are directly pressed on the two side end surfaces of the rectangular aluminum profile 3 to enhance the appearance.

[0039] The slider 7 and the linear guide rail 4 provide linear motion for the angle detection device, so that the angle detection sensor can perform angle detection within any effective bending range.

[0040] The limit collision block 11 is installed on the angle detection sensor fixing plate 8. When the angle detection is running, the limit collision block hits the limit stopper 5, and the limit stopper 5 is made of polyurethane, which can buffer a part of the impact force.

[0041] The synchronous belt fixing pressure plate 13 has reverse teeth that mesh with the left and right moving transmission synchronous belt of the angle detection sensor 21, and is locked on the angle detection synchronous belt connecting sheet metal 12 by screws. At the same time, the angle detection synchronous belt connecting sheet metal 12 is fixed to the angle detection sensor fixing plate 8. When the angle detection sensor moves left and right and the transmission synchronous belt 21 rotates with the pulley, it can drag the slider 7 to move left and right, thereby realizing the left and right movement function of the angle detection sensor 17.

[0042] The limit detection sheet metal 16 is installed on the angle detection synchronous belt connection sheet metal 12, and moves left and right with the angle detection sensor. When it moves to the left and right limit positions, it will be detected by the limit sensor 19, which will send a signal to stop the motor, limiting the angle detection sensor to move only within the effective travel range.

[0043] The synchronous belt supporting member 14 is made of nylon and has a groove on the upper part. During installation, the lower surface of the angle detection sensor that moves left and right to drive the synchronous belt 21 is attached to the groove. Since the span of the angle detection sensor that moves left and right to drive the synchronous belt 21 is relatively long, the provision of this member can effectively prevent the synchronous belt from shaking when the synchronous belt pulley rotates rapidly, thereby affecting the moving speed and accuracy of the angle detection sensor.

[0044] Component 22. The reduction motor provides power for the entire angle detection transmission device. The rotation of the motor is transmitted to the angle detection transmission driving shaft 30 through the belt drive, and the synchronous pulley installed on the angle detection transmission driving shaft 30 transmits the rotational motion to the angle detection sensor left and right moving transmission synchronous belt 21, so that the slider 7 connected to the angle detection sensor left and right moving transmission synchronous belt 21 makes a linear motion, and the left and right movement of the angle detection is realized by controlling the forward and reverse rotation of the motor.

[0045] The reduction motor 22 is mounted on the reduction motor mounting seat 23. A reduction motor adjusting screw 25 is provided below the reduction motor mounting seat 23. By adjusting this screw, the tightness of the reduction motor output synchronous belt 27 can be easily adjusted.

[0046] The driven shaft bearing seat 34 is responsible for installing the entire driven shaft and the transmission pulley part, and the driven shaft bearing seat connecting plate 40 is fixed on the top. At the same time, the driven shaft bearing seat connecting plate 40 can slide freely on the driven shaft bearing seat adjusting guide rod 42. Two long screws inserted through the driven shaft bearing seat adjusting plate 41 are screwed into the threaded holes on the driven shaft bearing seat connecting plate 40. By screwing these screws, the angle detection sensor can be tightened to move the transmission synchronous belt 21 left and right, thereby improving the movement stability and accuracy of the angle detection sensor.
