Description

Technical Field

[0001] The utility model relates to the technical field of machining, in particular to a grinding device for a blade. Background Art

[0002] During the blade machining process, it is necessary to grind the front side, the back side and the cutting edge of the blade. Due to different machining positions, after completing the machining of one process, it is necessary to switch to the next working station to continue the machining of the next process. When transferring the blade between different processes, a manipulator can be used to grab the blade and move it from the positioning tooling of the previous process to the positioning tooling of the next process. During the blade position conversion process, since the surfaces of the blade machined twice are different, the manipulator needs to turn over the blade when grabbing the blade and putting it into the fixture of the next process. If a high-precision multi-axis manipulator is used, the multi-axis manipulator can automatically perform the turning operation, but the multi-axis manipulator often has a high equipment cost, which is difficult for small and medium-sized enterprises to bear. The method of manually installing the blade on the positioning tooling of the next working station has low efficiency and also has potential safety hazards. A relatively low-cost approach is to set up a turning tooling near the grinding workbench. The manipulator first clamps the blade onto the turning tooling, and the turning tooling turns over the blade. Then the manipulator grabs the turned-over blade and puts it into the tooling of the next process for the next process machining. Although this method has low cost, the manipulator needs to perform two grabs, resulting in low work efficiency. Summary of the Invention

[0003] The purpose of the utility model is to provide a blade grinding device aiming at the defects existing in the above-mentioned prior art, which can automatically and quickly turn over the blade after one surface of the blade grinding is completed, reducing both the processing cost and ensuring the processing efficiency.

[0004] The technical solution adopted by the present utility model to achieve the above object is as follows: A blade grinding and processing device includes a bed body, a processing workbench, a grinding wheel frame and a grinding wheel. The grinding wheel frame is arranged on one side of the processing workbench, the grinding wheel is arranged on the grinding wheel frame, and a grinding positioning tooling is arranged on the processing workbench opposite to the grinding wheel frame. A blade turning tooling is also arranged on the processing workbench on one side of the grinding positioning tooling. The grinding positioning tooling includes a grinding tooling installation base, a tool processing positioning disk, a positioning disk rotating shaft, a rotating shaft driving component, and a protective cover I. The rotating shaft driving component is installed on the grinding tooling installation base, the output end of the rotating shaft driving component is connected to the positioning disk rotating shaft and can drive the positioning disk rotating shaft to rotate. The protective cover I is installed on the grinding tooling installation base and covers the rotating shaft driving component. The end of the positioning disk rotating shaft passes through the protective cover I and is connected to the tool processing positioning disk. A rotating mechanism capable of driving the whole grinding positioning tooling to rotate is arranged on the lower side of the grinding tooling installation base. The grinding positioning tooling can rotate to a position where the tool processing positioning disk is opposite to the blade turning tooling. The blade turning tooling includes a blade turning positioning disk and a blade turning driving component connected to the lower side of the blade turning positioning disk and capable of driving the blade turning positioning disk to move towards the front of the tool processing positioning disk.

[0005] A further technical solution of the present utility model is: The rotating shaft driving component includes a rotating shaft driving motor, a driving belt pulley, a driven belt pulley, and a transmission belt. The positioning disk rotating shaft is installed on the upper surface of the grinding tooling installation base through a support seat. The output end of the rotating shaft driving motor is connected to the driving belt pulley. The driven belt pulley is connected to one end of the positioning disk rotating shaft inside the protective cover I. One end of the positioning disk rotating shaft protruding from the protective cover I is connected to the tool processing positioning disk. The transmission belt is connected between the driving belt pulley and the driven belt pulley.

[0006] A further technical solution of the present utility model is: The blade turning driving component includes a slide rail III, a slider III, and a turning cylinder. The slide rail III is installed on the processing workbench on one side of the grinding positioning tooling. The slider III is matched with the slide rail III and the slider III can slide relative to the slide rail III. The base of the blade turning positioning disk is connected to the slider III through a connecting device to form an integral body. The turning cylinder is installed on the surface of the processing workbench outside the slide rail III through an installation bracket. The end of the piston rod of the turning cylinder is connected to the base of the blade turning positioning disk through a connecting device. When the turning cylinder works, it can push the whole blade turning positioning disk to move relative to the slide rail III. The heights of the blade turning positioning disk and the tool processing positioning disk in the vertical direction are equal.

[0007] A further technical solution of the present utility model is: A protective cover II covering the slide rail III and the slider III is arranged on the processing workbench. The protective cover II is a retractable bellows protective cover.

[0008] The blade grinding and processing device of the utility model has the following beneficial effects: on the processing workbench on one side of the grinding positioning tooling, a blade turning tooling capable of automatic movement is arranged. After the blade is ground, the grinding positioning tooling automatically turns to the side where the blade turning tooling is located. The blade turning tooling is controlled to move inward to the tool processing positioning disc of the grinding positioning tooling. When the blade turning positioning disc of the blade turning tooling is close to the tool processing positioning disc, the blade that has been processed on the tool processing positioning disc is transferred to the blade turning positioning disc, thus completing the blade turning. It can be directly grabbed by the manipulator to process the unprocessed side surface of the blade in the next process. After one side of the blade grinding is completed, the blade turning can be automatically and quickly completed, which not only reduces the processing cost but also ensures the processing efficiency.

Detailed Embodiment

[0016] As Figures 1 to 5As shown in the figure, the blade grinding and processing device of the present utility model includes a bed 1, a processing workbench 3, a grinding wheel frame 5 and a grinding wheel 6. The grinding wheel frame 5 is arranged on one side of the processing workbench 3, and the grinding wheel 6 is arranged on the grinding wheel frame 5. The bed 1, the grinding wheel 6 and the grinding wheel frame 5 are not the inventive points of this patent and are all existing designs, so no detailed description will be given here. On the processing workbench 3, a grinding positioning tooling 4 is arranged on the side opposite to the grinding wheel frame 5, and a blade turning tooling 2 is also arranged on the processing workbench 3 on the side of the grinding positioning tooling 4. The grinding positioning tooling 4 is used to position the blade parts that need to be ground, and the blade turning tooling 2 is used to turn over the blade parts that have completed the processing of one surface so that the next process can directly process them.

[0017] As Figures 2 to 4 shown, the grinding positioning tooling 4 includes a grinding tooling installation base 14, a tool processing positioning disc 8, a positioning disc rotating shaft 9, a rotating shaft driving component, and a protective cover I 7. The grinding tooling installation base 14 is located on the upper side of the processing workbench 3. A rotating mechanism capable of driving the whole grinding positioning tooling 4 to rotate is arranged on the lower side of the grinding tooling installation base 14, that is, a rotating mechanism is also arranged between the surface of the grinding tooling installation base 14 and the processing workbench 3. The rotating mechanism supports the grinding tooling installation base 14 and can drive the grinding tooling installation base 14 to rotate 90 degrees relative to the processing workbench 3 towards the side where the blade turning tooling 2 is located, so that the devices on the grinding tooling installation base 14 rotate together with the grinding tooling installation base 14. After rotating 90 degrees, the grinding positioning tooling 4 can rotate to a position where the tool processing positioning disc 8 is facing the blade turning tooling 2, that is, the tool processing positioning disc 8 is facing the blade turning positioning disc 11, as Figure 5 shown. The rotating mechanism is an existing mechanism that can be directly purchased, and its structure will not be introduced in detail here. The rotating shaft driving component is installed on the grinding tooling installation base 14. The output end of the rotating shaft driving component is connected to the positioning disc rotating shaft 9 and can drive the positioning disc rotating shaft 9 to rotate. The protective cover I 7 is installed on the grinding tooling installation base 14 and covers the rotating shaft driving component. The end of the positioning disc rotating shaft 9 passes through the protective cover I 7 and is connected to the tool processing positioning disc 8. The tool processing positioning disc 8 is an electromagnetic suction positioning disc, which has magnetism when energized and no magnetism when powered off. It can suck the blade parts when energized and release the blade parts when powered off and without magnetism. The outer surface of the top wall of the protective cover I 7 is connected with a cooling oil spraying device 13. In this embodiment, as Figure 3As shown in the figure, the rotating shaft driving assembly includes a rotating shaft driving motor 18, a driving pulley 15, a driven pulley 16, and a transmission belt 17. The positioning disk rotating shaft 9 is installed on the upper surface of the grinding tooling installation base 14 through a support base. The output end of the rotating shaft driving motor 18 is connected to the driving pulley 15. The driven pulley 16 is connected to one end of the positioning disk rotating shaft 9 located inside the protection cover I 7. One end of the positioning disk rotating shaft 9 protruding from the protection cover I 7 is connected to the tool processing positioning disk 8. The transmission belt 17 is connected between the driving pulley 15 and the driven pulley 16. The output end of the rotating shaft driving motor 18 is connected to the driving pulley 15 through a connecting device. When the rotating shaft driving motor 18 works, it drives the driving pulley 15 to rotate. The driving pulley 15 drives the driven pulley 16 to rotate through the transmission belt 17. The rotation of the driven pulley 16 drives the positioning disk rotating shaft 9 to rotate. The positioning disk rotating shaft 9 drives the tool processing positioning disk 8 to rotate together.

[0018] As Figure 2 , Figure 4 , Figure 5 shown, the blade turning tooling 2 includes a blade turning positioning disk 11 and a blade turning driving assembly connected to the lower side of the blade turning positioning disk 11 and capable of driving the blade turning positioning disk 11 to move towards the front of the tool processing positioning disk 8. The blade turning positioning disk 11 is an electromagnetic suction positioning disk, which has magnetism when energized and no magnetism when de-energized. When energized, it can hold the blade parts, and when de-energized, it releases the blade parts due to no magnetism. The blade turning driving assembly includes a slide rail III 19, a slider III 20, and a turning cylinder 10. The slide rail III 19 is installed on the processing workbench 3 on one side of the grinding positioning tooling 4. The slider III 20 cooperates with the slide rail III 19 and the slider III 20 can slide relative to the slide rail III 19. The base of the blade turning positioning disk 11 is connected to the slider III 20 through a connecting device to form an integral body, that is, the blade turning positioning disk 11 can move relative to the slide rail III 19 on the processing workbench 3 together with the slider III 20. The turning cylinder 10 is installed on the surface of the processing workbench 3 outside the slide rail III 19 through a mounting bracket. The end of the piston rod of the turning cylinder 10 is connected to the base of the blade turning positioning disk 11 through a connecting device. When the turning cylinder 10 works, it can push the whole blade turning positioning disk 11 to move relative to the slide rail III 19. The blade turning positioning disk 11 and the tool processing positioning disk 8 are at the same height in the vertical direction. A protection cover II 12 covering the slide rail III 19 and the slider III 20 is provided on the processing workbench 3. The protection cover II 12 is a telescopic bellows protection cover. When the turning cylinder 10 works to push the whole blade turning positioning disk 11 to move inward relative to the slide rail III 19, the protection cover II 12 contracts and shortens inward. When the turning cylinder 10 works to push the whole blade turning positioning disk 11 to move outward relative to the slide rail III 19, the protection cover II 12 extends and lengthens outward. The protection cover II 12 always covers the slide rail III 19 to prevent impurities from falling onto the slide rail III 19.

[0019] During operation, the two sides of the blade part are surface A and surface B respectively. The manipulator grabs the blade part to be processed from the feeding device and places it on the tool processing positioning disc 8 of the grinding positioning tooling 4. The tool processing positioning disc 8 is electrified to adsorb the blade part. The rotating shaft driving assembly makes the positioning disc rotating shaft 9 rotate. The grinding wheel 6 grinds the surface (surface A) of the blade part facing the grinding wheel 6. After this grinding process is completed, the rotating mechanism drives the grinding positioning tooling 4 to rotate 90 degrees towards the side where the blade turning tooling 2 is located. The tool processing positioning disc 8 is directly opposite to the blade turning positioning disc 11. At this time, control the turning cylinder 10 to work, pushing the whole blade turning positioning disc 11 to move inwards relative to the slide rail III 19 until the blade turning positioning disc 11 is close to the outer surface of the tool processing positioning disc 8. Control the tool processing positioning disc 8 to cut off the power supply to release the blade part, and at the same time control the blade turning positioning disc 11 to be electrified. The blade turning positioning disc 11 adsorbs and positions the blade part on its surface, and the blade part is turned over. Control the turning cylinder 10 to work in the reverse direction, and the whole blade turning positioning disc 11 moves outwards relative to the slide rail III 19. The manipulator can grab the blade part that has been turned over on the blade turning positioning disc 11 and place it in the next process processing tooling to continue processing the B surface of the blade part. At the same time, the manipulator also grabs another unprocessed blade part to the tool processing positioning disc 8. The rotating mechanism drives the grinding positioning tooling 4 to turn towards the side where the grinding wheel 6 is located, and the grinding wheel 6 grinds the A surface of the second blade part.
