Description

Technical fields:

[0001] This utility model belongs to the field of multi-wedge belt production technology, and specifically relates to a transmission belt cutting and correction device. Background technology:

[0002] In the production process of multi-ribbed belt drives, the belt drum needs to be placed on rollers, tensioned, and then cut. During the cutting process, the belt drum will move left and right on the rollers due to changes in tension, causing the belt drum to deviate and resulting in inconsistent widths of the cut drive belts, thus affecting the quality of the drive belt.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content:

[0004] The purpose of this invention is to provide a transmission belt cutting and correction device, thereby overcoming the defects in the prior art.

[0005] To achieve the above objectives, this utility model provides a transmission belt cutting and correction device, including a base plate, a tensioning platform, a drive roller mechanism, a tensioning roller mechanism, a Z-axis moving mechanism, a detection mechanism, and a correction mechanism. The base plate is equipped with a Z-axis moving mechanism, the tensioning platform is mounted on the Z-axis moving mechanism, and the correction mechanism is mounted on the tensioning platform. A tensioning roller mechanism is oscillatingly mounted on the correction mechanism. The drive roller mechanism is located below the tensioning roller mechanism, and a detection mechanism is mounted on the drive roller mechanism. The detection mechanism is communicatively connected to the correction mechanism. The drive roller mechanism includes a drive roller, and the tensioning roller mechanism includes a tensioning roller. A belt drum is fitted onto the drive roller and the tensioning roller. A detection point is set on the left side of the belt drum corresponding to the drive roller. The detection end of the detection mechanism is located at the detection point. The detection mechanism detects the displacement and pressure values ​​at the detection point. Based on the detection data, the correction mechanism drives the tensioning roller to oscillate, ensuring that the left side of the belt drum remains at the detection point position, preventing the belt drum from moving left or right.

[0006] Preferably, in the technical solution, the detection mechanism includes a cylinder, a guide rail slide, a mechanical displacement sensor, a diaphragm sensor, and a sliding bearing. The cylinder and the guide rail slide are mounted on the drive roller mechanism. The output end of the cylinder is connected to the guide rail slide. A mechanical displacement sensor is mounted at the front end of the guide rail slide, and the detection point is located on the moving path of the mechanical displacement sensor. The sliding bearing is mounted on the drive roller, and a diaphragm sensor is mounted on the sliding bearing. The diaphragm sensor is located at the detection point, and the mechanical displacement sensor is located above the diaphragm sensor. The mechanical displacement sensor detects the displacement value of the left side of the belt drum, and the diaphragm sensor detects the pressure value of the left side of the belt drum.

[0007] Preferably, in the technical solution, the tensioning roller mechanism includes a tensioning roller, a roller seat, and a connecting member. The tensioning roller is mounted on the roller seat, and the connecting member is mounted on the roller seat. The connecting member is connected to the correction mechanism.

[0008] Preferably, in the technical solution, the correction mechanism includes a correction servo motor, a belt drive mechanism, a lead screw, an X-axis guide rail pair, a Y-axis guide rail pair, a rotating shaft, a swing shaft, and a bearing seat. The correction servo motor, lead screw, Y-axis guide rail pair, and bearing seat are mounted on the tensioning platform. The X-axis guide rail pair and swing shaft are mounted on the roller seat, with the swing shaft housed within the bearing seat. A connecting piece is fitted onto the lead screw.

The X-axis guide rail pair, Y-axis guide rail pair, and rotating shaft form a forward, backward, left, and right moving guide rail pair. The correction servo motor is communicatively connected to a mechanical displacement sensor and a diaphragm sensor. Based on the detection data from the mechanical displacement sensor and the diaphragm sensor, the correction servo motor drives the lead screw to rotate. The lead screw, via the roller seat, drives the tensioning roller to rotate around the swing shaft as its center. Through the forward, backward, left, and right moving guide rail pair, the tensioning roller moves forward and backward, ensuring that the left side of the tensioning roller always faces the mechanical displacement sensor and the diaphragm sensor, preventing the belt from deviating.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] By detecting the displacement and pressure values ​​on the left side of the tension roller in real time, when the pressure value is lower than the set range, the correction servo motor drives the tension roller to move back and forth through the cooperation of the front-back and left-right moving guide rail pair and the swing shaft, adjusting the tension force on both sides of the belt drum, so that the left side of the belt drum always faces the mechanical displacement sensor and diaphragm sensor, preventing the belt drum from deviating during the cutting process and ensuring that the cutting width of the transmission belt is consistent.

The tensioning servo motor 50 and the Z-axis guide rail pair 51 are mounted on the base plate 1. The tensioning servo motor 50 is connected to the tensioning platform 2, which is mounted on the Z-axis guide rail pair 51. The tensioning platform 2 is provided with a correction mechanism 7, and the correction mechanism 7 is oscillatingly mounted on the correction mechanism 7. The active roller mechanism 3 is located below the tensioning roller mechanism 4, and the active roller mechanism 3 is provided with a detection mechanism 6. The detection mechanism 6 is communicatively connected to the correction mechanism 7.

[0018] The active roller mechanism 3 includes an active roller 30 and an active roller seat 31. The active roller 30 is mounted on the active roller seat 31. The tension roller mechanism 4 includes a tension roller 40, a roller seat 41, and a connecting member 42. The tension roller 40 is mounted on the roller seat 41, and the connecting member 42 is mounted on the roller seat 41. The belt sleeve is fitted onto the active roller 30 and the tension roller 40. A detection point is set on the left side of the belt sleeve corresponding to the active roller 30. A corresponding center point 8 is set on one side of both the active roller 30 and the tension roller 40.

[0019] The detection mechanism 6 includes a cylinder 60, a guide rail slide 61, a mechanical displacement sensor 62, a diaphragm sensor 63, and a sliding bearing 64. The cylinder 60 and the guide rail slide 61 are mounted on the drive roller seat 31. The output end of the cylinder 60 is connected to the guide rail slide 61. A mechanical displacement sensor 62 is mounted at the front end of the guide rail slide 61, and the detection point is located on the moving path of the mechanical displacement sensor 62. The sliding bearing 64 is mounted on the drive roller 30, and a diaphragm sensor 63 is mounted on the sliding bearing 64. The diaphragm sensor 63 is located at the detection point, and the mechanical displacement sensor 62 is located above the diaphragm sensor 63. The mechanical displacement sensor 62 detects the displacement value of the left side of the belt drum, and the diaphragm sensor 63 detects the pressure value of the left side of the belt drum.

[0020] The correction mechanism 7 includes a correction servo motor 70, a belt drive mechanism 71, a lead screw 72, an X-axis guide rail pair 73, a Y-axis guide rail pair 74, a rotating shaft 75, a swing shaft 76, and a bearing 77. The correction servo motor 70, lead screw 72, Y-axis guide rail pair 74, and bearing 77 are mounted on the tensioning platform 2. The X-axis guide rail pair 73 and the swing shaft 76 are mounted on the roller seat 41, with the swing shaft 76 housed within the bearing 77. A connecting piece 42 is fitted onto the lead screw 72. The correction servo motor 70 and the lead screw 72 are connected via the belt drive mechanism 71. The Y-axis guide rail pair 74 and the X-axis guide rail pair 73 are connected via... The belt is connected by a rotating shaft 75. The X-axis guide rail pair 73 and the Y-axis guide rail pair 74, together with the rotating shaft 75, form a front-back and left-right moving guide rail pair. The correction servo motor 70 is communicatively connected to the mechanical displacement sensor 62 and the diaphragm sensor 63. Based on the detection data of the mechanical displacement sensor 62 and the diaphragm sensor 63, the correction servo motor 70 drives the lead screw 72 to rotate. The lead screw 72 drives the tension roller 40 to rotate around the swing shaft 76 as the rotation center via the roller seat 41. Through the front-back and left-right moving guide rail pair, the tension roller 40 moves back and forth, so that the left side of the tension roller 40 always faces the mechanical displacement sensor 62 and the diaphragm sensor 63, preventing the belt from running off-track.

[0021] During operation, the robotic arm places the belt drum onto the drive roller 30 and tension roller 40, the center 8 is closed, the tension servo motor 50 is started, which drives the tensioning platform 2 to move upward to tension the belt drum. The asynchronous motor connected to the drive roller 30 is started, and the drive roller 30 drives the belt drum to rotate. The manual operation first trims the left side of the belt drum to remove the burrs.

[0022] After the trimming is completed, the cylinder 60 drives the mechanical displacement sensor 62 to extend forward. The mechanical displacement sensor 62 contacts the left side of the belt drum to detect the displacement value, and the diaphragm sensor 63 contacts the left side of the belt drum to detect the pressure value. When the pressure value is in the range of 100-300KG, the transmission belt on the belt drum is cut.

[0023] During the cutting process, the displacement and pressure values ​​on the left side of the tension roller are monitored in real time. When the displacement value becomes negative and the pressure value gradually decreases, it indicates that the belt drum tends to move to the right. The correction servo motor 70 controls the lead screw 72 to rotate, driving the tension roller 40 forward, increasing the tension on the right side of the belt drum, suppressing the rightward movement of the belt drum, and ensuring that the left side of the belt drum always stays close to the mechanical displacement sensor and diaphragm sensor. Conversely, when the displacement value becomes positive and the pressure value gradually increases, it indicates that the belt drum tends to move to the left. The correction servo motor 70 controls the lead screw 72 to rotate in the opposite direction, driving the tension roller 40 backward, increasing the tension on the left side of the belt drum, suppressing the leftward movement of the belt drum, preventing the belt drum from deviating during the cutting process, and ensuring a consistent cutting width of the transmission belt.
