They perform surface treatments such as grinding, polishing, and deburring on workpieces through rotating sand belts. However, the existing belt sanders on the market mainly use fixed sand belts, and this design has some limitations in practical applications.

[0003] Firstly, fixed belt sanders cannot dynamically adjust the workpieces during the processing, which limits the processing range and flexibility of the workpieces. Since the sand belt is fixed, the workpiece needs to be adjusted according to the position of the sand belt, and it is difficult to achieve precise grinding and polishing effects in the processing of workpieces with complex shapes.

[0029] Embodiment 1

[0030] Refer to Figure 1 As shown, this embodiment provides a hydraulic controlled triangular abrasive belt machine, which includes: a floating mechanism 100, the floating mechanism 100 includes a floating module 110 and a mounting plate 120, and the mounting plate 120 is connected to the working end of the floating module 110; a driving mechanism 200, the driving mechanism 200 is connected to the mounting plate 120, and it includes a driving wheel 210, the driving wheel 210 is connected to the mounting plate 120 and rotates around its axis; a tensioning mechanism 300, which includes a tensioning wheel 310 and a moving module 320, one end of the moving module 320 is connected to the mounting plate 120 and extends in a direction away from the mounting plate 120, and the tensioning wheel 310 moves along the moving module 320; a grinding mechanism 400, the grinding mechanism 400 includes a grinding wheel 410, and the grinding wheel 410 is connected to the mounting plate 120; an abrasive belt 500, the abrasive belt 500 is sleeved on the outer surfaces of the driving wheel 210, the tensioning wheel 310 and the grinding wheel 410.

[0031] The hydraulic control triangular belt sander described in the present utility model precisely controls its overall operation process through the floating mechanism 100. The floating module 110, as the core component, features high responsiveness, high precision, and low friction. Thus, it can adjust the output force and operation position of the belt sander in real time, thereby ensuring the stability and precision during the grinding process. At the same time, the coordinated cooperation among the driving mechanism 200, the tensioning mechanism 300, and the grinding mechanism 400 realizes the stable installation of the belt 500, further improving the stability of the working process of the belt sander. Compared with the conventional belt sanders at the present stage, this application has the characteristics of stable operation process, high automation degree, fast response speed, and high adjustment precision, and has broad application prospects in this industry.

[0032] See Figure 1 As shown, in this embodiment, the floating mechanism 100 is connected to an external mobile device. The mounting plate 120 is used to provide a mounting platform for the driving mechanism 200, the tensioning mechanism 300, and the grinding mechanism 400. The floating module 110 combines the characteristics of electronic control and hydraulic power transmission. On the one hand, it can provide very precise position and speed control. On the other hand, due to the fast response characteristics of the motor and the hydraulic pump, the floating module 110 can start and stop quickly to adapt to rapidly changing operation requirements. In addition, the floating module 110 also has the characteristics of energy saving, high reliability, and strong fault detection ability. Thus, the present utility model creatively combines the grinding device with the floating module 110 to achieve the purpose of high-precision and adaptive processing.

[0033] See Figure 2 and Figure 3 As shown, in this embodiment, the mounting plate 120 is preferably a runway-shaped component. The floating mechanism 100 is connected to the center of one side of the mounting plate 120. The driving mechanism 200 and the grinding mechanism 400 are respectively arranged at both ends of the other side of the mounting plate 120. The tensioning mechanism 300 is arranged between the driving mechanism 200 and the grinding mechanism 400. Among them, the driving mechanism 200 is used to provide driving force for the belt 500. The grinding mechanism 400 directly contacts the component to be ground to achieve its grinding function. The tensioning mechanism 300 is used to adjust or replace the belt 500.

[0034] In this embodiment, the driving mechanism 200 further includes a rotary driver 220 and a first coupling. The driving wheel 210 is connected to the working end of the rotary driver 220 through the first coupling. Among them, the first coupling 230 can, while ensuring the connection between the driving wheel 210 and the rotary driver 220, reduce vibrations caused by factors such as manufacturing errors, temperature changes, and load changes by absorbing radial and axial deviations between shafts, thereby achieving the purpose of reducing friction and wear and extending the service life of the equipment. Further, the driving mechanism 200 in this embodiment further includes a bearing seat 231, a first bearing 232, a driving shaft 233, and a locking member 234. The driving shaft 233 passes through the driving wheel 210. The first bearing 232 is sleeved on the surface of the driving shaft 233. The bearing seat 231 is buckled around the first bearing 232 and is connected to the driving shaft 233 through the locking member 234.

[0035] See Figures 4 to 6 As shown, the tensioning mechanism 300 includes a pushing driver 340 and a carriage 330. One side of the carriage 330 is slidably connected to the moving module 320, and the other side is connected to the tensioning wheel 310. The pushing driver 340 is connected to the mounting plate 120, and its working end is connected to the carriage 330. Specifically, when the carriage 330 in this embodiment moves in a direction away from the mounting plate 120, the tensioning wheel 310 can increase the tension of the abrasive belt 500, thereby ensuring the stability of the abrasive belt 500 during the working process; when the carriage 330 moves in a direction close to the mounting plate 120, the abrasive belt 500 can gradually disengage from each wheel body, and at this time, the abrasive belt 500 can be replaced or adjusted. In this embodiment, the pushing driver 340 is a pushing cylinder. The tensioning mechanism 300 further includes a manual valve 350. Air source interfaces 360 are provided on both the manual valve 350 and the pushing driver 340. Among them, the manual valve 350 further includes a handle 351. The air source interface 360 is switched through the handle 351 to adjust the opening and closing of the pushing cylinder. Based on this, the handle 351 can control the expansion and contraction of the pushing driver 340, thereby improving the flexibility and controllability of the application. In addition, a muffler 352 is provided on the manual valve 350 in this embodiment.

[0036] In this embodiment, the tension pulley 310 is disposed inside the carriage 330. The tensioning mechanism 300 further includes a deviation rectifying component 370. The deviation rectifying component 370 includes a deviation rectifying screw 371 and a deviation rectifying shaft 372. The deviation rectifying shaft 372 penetrates through the tension pulley 310. One end thereof is connected to the carriage 330 on one side of the tension pulley 310 through the deviation rectifying screw 371, and the other end is provided with a shoulder bolt 373 which is fitted into the carriage 330 on the other side of the tension pulley 310. Through the arrangement of the deviation rectifying component 370, the present application can ensure the accurate installation position of the abrasive belt 500, thereby avoiding the problem that the abrasive belt 500 deviates or even detaches during the rotation process. Specifically, the tensioning mechanism 300 further includes a second bearing 381, a bearing cover 382, a snap ring 384 and a seal 383. The second bearing 381 is disposed around the outer surface of the deviation rectifying shaft 372 and is connected to the deviation rectifying shaft 372 through the bearing cover 382. The snap ring 384 is disposed between the deviation rectifying shaft 372 and the tension pulley 310. The present application fixes the relative position between the deviation rectifying shaft 372 and the tension pulley 310 through the snap ring 384 to achieve the deviation rectifying effect. The seal 383 is embedded between the bearing cover 382 and the deviation rectifying shaft 372, thereby realizing the connection between the above structures. Among them, the seal 383 is preferably a rubber sealing ring which is embedded between the bearing cover 382 and the deviation rectifying shaft 372 to achieve dust protection for the second bearing 381.

[0037] See Figure 7 As shown, the grinding mechanism 400 further includes a follower shaft 420. The grinding wheel 410 is rotatably connected to the mounting plate 120 through the follower shaft 420. During actual use, the grinding wheel 410 abuts against the surface of the element to be ground.

[0038] This embodiment further includes a control system. The driving mechanism 200, the tensioning mechanism 300 and the floating mechanism 100 are respectively connected to the control system. During actual production and processing, an operator can perform real-time regulation on the above structures through the control system, thereby improving the flexibility of use of the present device. Parameters can also be preset through the control system, thereby improving the automation degree of the present device.

[0040] This embodiment provides a grinding device, which includes the hydraulic control triangular abrasive belt machine described in Embodiment One and a moving mechanism 600. Among them, the moving mechanism 600 is preferably a transfer robotic arm.

[0041] In summary, for the hydraulic control triangular belt sander and grinding equipment of the present utility model, the floating mechanism 100 precisely controls the overall operation process. Among them, the floating module 110, as the core component, has the characteristics of high responsiveness, high precision, and low friction. Thus, the output force and operation position of the sander can be adjusted in real time, thereby ensuring the stability and precision during the grinding process. At the same time, the coordinated cooperation among the driving mechanism 200, the tensioning mechanism 300, and the grinding mechanism 400 realizes the stable installation of the abrasive belt 500, further improving the stability of the working process of the sander. Compared with the conventional belt sanders at the present stage, this application has the characteristics of stable operation process, high automation degree, fast response speed, and high adjustment precision, and has broad application prospects in this industry.
