Description

Technical Field

[0001] This utility model relates to the field of grinding technology, and in particular to a combination of grinding and cleaning for chamfering of pultruded main beams. Background Technology

[0002] Pultrusion molding, as an important technology in the field of composite material processing, is widely used in the manufacture of structural components in bridges, buildings, and transportation due to its advantages such as high production efficiency, stable product performance, and good molding quality. Among these, pultruded main beams, as the core load-bearing components, have their processing precision and surface quality directly affecting the safety and service life of the overall structure. In the production process of pultruded main beams, to avoid sharp edges that could cause installation difficulties or stress concentration and structural damage during use, the chamfers at the ends or connections of the main beams need to be ground to ensure a smooth and flat finish that meets assembly and usage standards. Therefore, a combination of chamfering, grinding, and cleaning technology for pultruded main beams is designed.

[0003] In existing technologies, chamfering and cleaning operations are mostly carried out in a separate operation mode. That is, after the chamfering process is completed by specialized chamfering equipment, the grinding area is cleaned of debris by separately configured cleaning equipment. In some small production scenarios, manual cleaning with hand tools is even required, resulting in obvious gaps between processes. After grinding, the main beam needs to be transferred to the cleaning station or wait for the cleaning equipment to be debugged and ready, which adds extra process changeover time and reduces overall processing efficiency.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Please refer to Figures 1 to 5 Example 1: This utility model proposes a combination for chamfering, grinding, and cleaning of pultruded main beams, comprising: a base 1; four casters 11 are installed at the lower end of the base 1; a base plate 12 is installed on the base 1; a movable plate 13 that can slide left and right is installed on the base plate 12; a back plate 21 is installed on the movable plate 13; a lifting plate 22 that can slide up and down is installed on the back plate 21; a movable plate 23 that can slide back and forth is installed on the lifting plate 22; two sliding groove seats 3 are installed on the movable plate 23; a sliding plate 31 is installed on each of the two sliding groove seats 3; a connecting seat 33 is installed on the sliding plate 31; a housing 34 is fixedly installed on the connecting seat 33; a chamfering grinding wheel 341 is installed on the housing 34 via bearings; a gearbox 342 is installed on the housing 34; a first electric motor 343 is installed on the gearbox 342; a support column 35 is fixed on the housing 34; and a cleaning brush 356 is provided on the support column 35.

[0025] In this embodiment of the utility model, a lead screw 131 is mounted on the base plate 12 via bearings. The lead screw 131 is threadedly engaged with the lower end of the movable plate 13. A motor base 132 is fixedly mounted on the left end of the base plate 12, and a second motor 133 is mounted on the motor base 132. The output shaft of the second motor 133 is connected to the left end of the lead screw 131 via a coupling. Its function is to use the second motor 133 as a power source to accurately transmit power to the lead screw 131 via the coupling. By utilizing the threaded engagement between the lead screw 131 and the lower end of the movable plate 13, the rotational motion of the second motor 133 is converted into the linear motion of the movable plate 13 along the base plate 12, thereby realizing the automatic adjustment of the left and right positions of the movable plate 13 without manual pushing, greatly improving the adjustment efficiency and accuracy, and meeting the precise control requirements for grinding and cleaning positions in the processing of pultruded main beams.

[0026] In this embodiment of the utility model, two brackets 2 are bolted to the movable plate 13, and the back plate 21 is bolted to the two brackets 2. A second lead screw 211 is mounted on the back plate 21 via bearings. The second lead screw 211 is threadedly engaged with the right end of the lifting plate 22. A first right-angle seat 213 is mounted on the upper end of the back plate 21, and a first handwheel 212 is mounted on the first right-angle seat 213. The first handwheel 212 is connected to the upper end of the second lead screw 211 via a coupling. A first locking bolt 2131 is threaded onto the first right-angle seat 213. The first locking bolt 2131 is tightened against the rotating shaft of the first handwheel 212. Its function is: when the operator rotates the first handwheel 212, the shaft is engaged via the coupling. The device drives the second lead screw 211 to rotate smoothly along the bearing on the back plate 21. By utilizing the threaded engagement between the second lead screw 211 and the right end of the lifting plate 22, the rotational motion of the first handwheel 212 is converted into the vertical linear motion of the lifting plate 22 along the back plate 21, realizing precise manual adjustment of the height position of the lifting plate 22. This meets the grinding and cleaning needs of the pultruded main beam at different heights. The first locking bolt 2131 is used to tighten the shaft of the first handwheel 212. After the lifting plate 22 is adjusted to the target position, the first handwheel 212 is locked to prevent the second lead screw 211 from rotating unexpectedly due to external force or its own weight, which would cause the lifting plate 22 to shift. This ensures the stability of the lifting plate 22 during operation and improves processing accuracy.

[0027] In this embodiment of the invention, a No. 3 lead screw 221 is mounted on the lifting plate 22 via bearings. The No. 3 lead screw 221 is threadedly engaged with the right side of the moving plate 23. A second right-angle seat 223 is bolted to the front side of the lifting plate 22. A No. 2 handwheel 222 is mounted on the second right-angle seat 223. The No. 2 handwheel 222 is connected to the front end of the No. 3 lead screw 221 via a coupling. A second locking bolt 2231 is threaded onto the second right-angle seat 223. The second locking bolt 2231 is tightened against the rotating shaft of the No. 2 handwheel 222. Its function is that when the operator rotates the No. 2 handwheel 222, the power is transmitted to the No. 3 lead screw 221 via the coupling. Lever 221, through the threaded engagement between the No. 3 lead screw 221 and the right side of the moving plate 23, converts the rotational motion of the No. 2 handwheel 222 into the linear motion of the moving plate 23 along the lifting plate 22, thereby enabling precise manual adjustment of the front and rear positions of the moving plate 23. This adapts to the grinding and cleaning needs of different front and rear positions of the pultruded main beam. By tightening the shaft of the No. 2 handwheel 222 with the second locking bolt 2231, the No. 2 handwheel 222 and the No. 3 lead screw 221 can be locked to prevent accidental rotation due to external interference, which would cause the moving plate 23 to shift. This ensures the stability of the moving plate 23 during operation and improves the accuracy of grinding and cleaning.

[0028] In Example 2, based on Example 1, hydraulic rods 32 are installed on both slide seats 3. The piston rods of the hydraulic rods 32 are connected to the sliding plate 31. Their function is to use the hydraulic rods 32 as power output components, and with the help of the stable thrust and pull of hydraulic drive, drive the sliding plate 31 to slide smoothly along the slide seat 3, so as to realize the flexible adjustment of the position of the sliding plate 31.

[0029] In Example 3, based on Examples 1 and 2, a top plate 352 is fixed to the support column 35, a lifting plate 351 is installed on the support column 35, a hydraulic cylinder 353 is fixedly installed on the lifting plate 351, the piston rod of the hydraulic cylinder 353 is fixedly connected to the top plate 352, a reducer 354 is installed on the lifting plate 351, a cleaning brush 356 is installed on the output shaft of the reducer 354, and a third motor 355 is installed on the reducer 354. Its function is to drive the lifting plate 351 to move up and down along the support column 35 when the hydraulic cylinder 353 extends or retracts, thereby adjusting... The height of the cleaning brush 356 on the raised plate 351 is adjusted to ensure that the cleaning brush 356 can accurately fit the chamfered positions of different heights of the pultruded main beam, adapting to the cleaning needs of main beams of different specifications. At the same time, the third motor 355 provides rotational power to the cleaning brush 356. The power is reduced and amplified by the reducer 354 and then transmitted to the cleaning brush 356, so that the cleaning brush 356 obtains a suitable speed and torque. This can not only efficiently remove debris and dust from the chamfered area of ​​the main beam after grinding, but also avoid the brush from wearing out too quickly due to excessive speed or the cleaning effect being affected by insufficient torque.

[0030] The working principle of this embodiment is as follows: First, the equipment is moved to the pultrusion main beam processing station by the casters 11 at the lower end of the base 1. Then, the second motor 133 is started, and its output shaft drives the first lead screw 131 on the base plate 12 to rotate via the coupling. With the help of the threaded engagement between the first lead screw 131 and the lower end of the movable plate 13, the movable plate 13 is driven to slide left and right along the base plate 12 to adjust to the lateral corresponding position for grinding and cleaning operations. Then, the operator rotates the first handwheel 212 on the first right-angle seat 213, which is connected via the coupling. The device drives the second lead screw 211 on the back plate 21 to rotate. Through the threaded engagement between the second lead screw 211 and the right end of the lifting plate 22, the lifting plate 22 moves up and down along the back plate 21. After adjusting to the position suitable for the height of the main beam, the first locking bolt 2131 is tightened to lock the first handwheel 212. Then, the second handwheel 222 on the second right-angle seat 223 is rotated, which drives the third lead screw 221 on the lifting plate 22 to rotate through the coupling. Through the threaded engagement between the third lead screw 221 and the right side of the moving plate 23, the moving plate 22 is pushed. Plate 23 slides back and forth along lifting plate 22. After determining the front and rear position for operation, tighten the second locking bolt 2231 to lock the second handwheel 222. Then, start the hydraulic rod 32 on the slide seat 3. Its piston rod drives the sliding plate 31 to slide along the slide seat 3. Adjust the distance between the housing 34 connected to the connecting seat 33 on the two sliding plates 31 so that the chamfering grinding wheel 341 on the housing 34 fits against the chamfer of the main beam. At the same time, start the first motor 343. The power is transmitted to the chamfering grinding wheel 341 through the gearbox 342 to realize the grinding of the main beam. The grinding operation of the chamfer of the main beam: During the grinding process, the hydraulic cylinder 353 of the lifting plate 351 on the support 35 is started. Its piston rod drives the lifting plate 351 to move up and down along the support 35 through the fixed connection with the top plate 352. The height of the cleaning brush 356 is adjusted to fit the grinding part. Then the third motor 355 is started. The power is reduced and increased in torque by the reducer 354 to drive the cleaning brush 356 to rotate, so as to remove the debris and dust generated by grinding in time. Finally, the chamfer grinding and cleaning operation of the pultruded main beam is completed.
