Description

Technical Field

[0001] The present invention belongs to the technical field of grinding machine processing, and specifically relates to a four-axis blade peripheral grinding machine with a blanking function. Background Art

[0002] During the production process of blades, their shape and dimensional accuracy are crucial for subsequent use effects. Through the grinding process of a blade peripheral grinding machine, the shape and dimensions of the blades can be precisely adjusted to ensure their matching degree with processing equipment or tools, thereby improving the processing accuracy and stability.

[0003] The patent with the publication number CN115246085B discloses a blade flipping and positioning device for a peripheral grinding machine and its control method. The blade flipping and positioning device for a peripheral grinding machine includes a workbench, a material tray is installed on the workbench, and a number of horizontally arranged blade raw materials are placed in the material tray. It also includes a grasping mechanism and a flipping mechanism. The grasping structure is used to transfer the blade raw materials from the material tray to the flipping mechanism. The flipping mechanism includes a rotating component, a supporting component installed on the rotating component, and a limiting component for restricting the position of the blade raw materials. The rotating component drives the supporting component to rotate, and the supporting component has a horizontal state and a vertical state. Using the grasping mechanism to transfer the blades on the material tray, and the flipping mechanism operates to flip the blades from the horizontal state to the vertical state, which can widely adapt to different shapes and angles of blade raw materials, without the need for non-standard customization of the material tray for the blade raw materials, saving costs.

[0004] However, the above technical solution still has the following deficiencies in actual application: By using a manipulator to place the blade raw materials at the blade positioning location and perform subsequent grinding work, and in order to facilitate the manipulator to clamp the blades, a number of blades need to be placed vertically on the material tray. However, generally, the blades will go through other processes before grinding, and in order to facilitate collection and transportation, the blades are often centrally placed in a container or collection box. Due to the large number of blades, the blades will be stacked in a messy state in the container. Therefore, before blade grinding, it is not convenient to accurately place the blades vertically on the material tray, which affects the normal clamping of the blades by the manipulator and further affects the subsequent grinding efficiency.

[0033] Specifically, when the existing blade peripheral grinder is in use, the blade raw materials are placed at the blade positioning position by using the manipulator 3, and subsequent grinding work is carried out. Moreover, in order to facilitate the manipulator 3 to clamp the blades, multiple blades need to be placed vertically on the material tray 4. However, generally, the blades will go through other processes before grinding, and, for the convenience of collection and transportation, the blades are often concentrated and placed in a container or a collection box. Due to the large number of blades, the blades will be stacked in a messy state in the container. Therefore, before blade grinding, it is not convenient to accurately place the blades vertically on the material tray 4, thus affecting the normal clamping of the blades by the manipulator 3 and further affecting the subsequent grinding efficiency. Therefore, to solve the above problems, in this embodiment, when in use, a batch of trapezoidal blades with the same specifications are used. Such blades are relatively common in industrial processing, and their side inclination angles usually remain the same. According to the width of the trapezoidal blade, by driving the bidirectional threaded rod 56 to rotate through the motor seven 57, the distance between the two limit plates 21 is adjusted so that the distance between the two limit plates 21 is equal to the width of the trapezoidal blade. Moreover, by driving the threaded rod two 33 to rotate through the motor four 32, the L-shaped rod 38 and the connecting plate 37 move transversely to adjust the distance between the connecting plate 37 and the detection plate 22, and this distance is the same as the thickness of the trapezoidal blade. Moreover, the cylinder one 27 is used to drive the baffle 28 on the blanking channel 23 so that the distance between the end of the baffle 28 and the blanking plate 20 is equal to the thickness of the blade. Then, pour the blades in the container into the hopper 19. The blades will fall onto the blanking plate 20 along with the hopper 19 and the blanking channel 23. Moreover, since the distance between the end of the baffle 28 and the blanking plate 20 is equal to the thickness of the blade, and the distance between the two limiting plates 21 is equal to the width of the blade, multiple blades will slide onto the blanking plate 20 in an arranged state under the action of gravity. And multiple blades arranged on the blanking plate 20 will be blocked by the stopper 31 and will not continue to fall downward. Then, drive the first threaded rod 26 to rotate by means of the third motor 24, so that the second cylinder 29 moves on the first slide rod 25, align the pressing block 30 with the second blade from the bottom of the blanking plate 20, and drive the pressing block 30 to move by the second cylinder 29 to press the blade. Then, drive the blanking plate 20 to move along the X, Y, and Z axes by means of the guide rail mechanism 16. The guide rail mechanism 16 is a mechanism that can drive an object to move in the prior art and will not be elaborated here in detail. Make the bottom surface of the detection plate 22 fit with the upper surface of the material tray 4, and the end of the blanking plate 20 is aligned with the placement grid 47. Then, drive the fourth threaded rod 55 to rotate by means of the first motor 10, so that the stopper 31 slides on the blanking plate 20. When the stopper 31 no longer blocks the blade, the blade will fall downward along the detection plate 22 into the placement grid 47. Then, the stopper 31 resets. Repeat the above operations to place multiple blades into the placement grid 47 in sequence. Moreover, since the areas of the two end faces on both sides of the trapezoidal blade are different and the side surface is an inclined surface, when the blade falls into the placement grid 47 in a vertical state, the blade is prone to tipping and cannot be in a vertical state, which affects the normal clamping of the manipulator 3. And the orientation of each blade may also be inconsistent. Therefore, after the blade is clamped by the manipulator 3 to the clamping rod 9, the grinding effect will also be affected due to the inconsistent contact angle between the blade and the grinding wheel 5 and the grinding path. Therefore, to avoid this situation, according to the inclination degree of the inclined surface of the trapezoidal blade, drive the worm 51 to rotate by means of the sixth motor 53, so that multiple worm wheels 52 rotate simultaneously. Then, multiple support plates 48 also rotate simultaneously to make the support plates 48 parallel to the inclined surface of the blade in a vertical state. And drive the transmission plate 50 to slide on the material tray 4 by means of the fifth cylinder 54 to adjust the distance between the support plate 48 and one side inside the placement grid 47, so that when the inclined surface of the blade fits with the surface of the support plate 48, the end face with the largest area of the blade also fits with one side end face of the inner cavity of the placement grid 47. When the blade falls to the detection plate 22, it will first be blocked by the support block 35. At this time, according to the width of the blade, drive the third threaded rod 41 to rotate by means of the fifth motor 40, so that the threaded block 43 moves up and down, drive the adjusting rod 44 to slide on the fixed rod 42 by means of the connecting rod 46, adjust the distance between the two pressure sensors 45, and align the pressure sensors 45 with the two side edges of the blade. Then, drive the fixed rod 42 to move by means of the fourth cylinder 39 to make the pressure sensors 45 approach the blade until the pressure sensors 45 detect pressure. Since the blade on the detection plate 22 can only be in two states at this time, one is that the end face with the largest area is close to the pressure sensor 45,Another one is that the end face opposite to the end face with the largest area is close to the pressure sensor 45. When the end face with the largest area approaches the pressure sensor 45, the pressure sensor 45 will detect the pressure first. On the contrary, the pressure sensor 45 will detect the pressure later due to contact with the blade inclined surface. Thus, it can be judged what the orientation of the blade is at this time. Then, the feeding plate 20 is driven by the second motor 18 to rotate 180 degrees to adjust the orientation of the blade. Then, the support block 35 is driven by the third cylinder 36 to move so that the support block 35 no longer blocks the bottom of the blade, enabling it to fall into the placement grid 47. And the blade inclined surface falling into the placement grid 47 fits with the support plate 48, and the end face with the largest area fits with the inner end face of the placement grid 47, and is placed vertically in the placement grid 47. Then, by repeating the above operations, all the blades can be uniformly oriented and placed vertically in the placement grid 47. Then, the manipulator 3 sequentially clamps multiple blades to the clamping rod 9 for grinding; thus, by using the angle orientation unified type feeding mechanism, before grinding the blades, multiple blades stacked together can be separated one by one and placed vertically in the placement grid 47, and then clamped by the manipulator 3 to the clamping rod 9 for grinding. Furthermore, it avoids the situation that multiple blades are stacked in a messy state in the container, which is not convenient to accurately place the blades vertically on the tray 4 and affects the normal clamping of the blades by the manipulator 3, and is beneficial to improving the subsequent grinding efficiency. Moreover, the angles and orientations of the blades in each placement grid 47 are the same, so when the blades are clamped by the manipulator 3 to the clamping rod 9, the angles and orientations are also the same, and the grinding wheel 5 can grind according to a fixed grinding path, further improving the grinding effect.

[0034] In this embodiment, as Figure 3 shown, a support column 6 is fixedly connected to one side of the upper end face of the workbench 15, and a dressing disc 14 is rotatably arranged on one side of the upper end of the support column 6.

[0035] Specifically, during the use of the grinding wheel 5, it will gradually wear, resulting in a decline in grinding performance. Therefore, by driving the dressing disc 14 to rotate, the outer ring and end face of the grinding wheel 5 can be dressed by using the dressing disc 14, so as to restore its grinding ability, extend the service life of the grinding wheel and improve the grinding efficiency.

[0036] Working principle: According to the width of the trapezoidal blade, the distance between the two limiting plates 21 is adjusted by driving the bidirectional threaded rod 56 to rotate through the motor seven 57, so that the distance between the two limiting plates 21 is equal to the width of the trapezoidal blade. And, by driving the threaded rod two 33 to rotate through the motor four 32, the L-shaped rod 38 and the connecting plate 37 move horizontally to adjust the distance between the connecting plate 37 and the detection plate 22, and this distance is the same as the thickness of the trapezoidal blade. Also, the baffle 28 is driven by the cylinder one 27 on the blanking channel 23, so that the distance between the end of the baffle 28 and the blanking plate 20 is equal to the thickness of the blade. Then, the blades in the container are poured into the hopper 19, and the blades will fall onto the blanking plate 20 along with the hopper 19 and the blanking channel 23. And, since the distance between the end of the baffle 28 and the blanking plate 20 is equal to the thickness of the blade, and the distance between the two limiting plates 21 is equal to the width of the blade, so, multiple blades will slide onto the blanking plate 20 in an arranged state under the action of gravity, and multiple blades arranged on the blanking plate 20 will be blocked by the stopper 31 and will not continue to fall downward. Then, by driving the threaded rod one 26 to rotate through the motor three 24, the cylinder two 29 moves on the slide rod one 25, so that the pressing block 30 aligns with the second last blade from the bottom on the blanking plate 20, and the cylinder two 29 drives the pressing block 30 to move to press the blade. Then, the guide rail mechanism 16 is used to drive the blanking plate 20 to move along the X, Y, and Z axes. The guide rail mechanism 16 is a mechanism that can drive an object to move in the prior art, and will not be elaborated here too much. Make the bottom of the detection plate 22 fit the upper surface of the tray 4, and the end of the blanking plate 20 aligns with the placement grid 47. Then, by driving the threaded rod four 55 to rotate through the motor one 10, the stopper 31 slides on the blanking plate 20. When the stopper 31 no longer blocks the blade, the blade will fall downward along the detection plate 22 into the placement grid 47. Then, the stopper 31 resets, and by repeating the above operations, multiple blades can be placed in the placement grid 47 in sequence. And, since the areas of the two end faces of the trapezoidal blade are different, and the side face is an inclined surface, so, when the blade falls into the placement grid 47 in a vertical state, the blade is prone to tipping and cannot be in a vertical state, which affects the normal clamping of the manipulator 3. Also, the orientation of each blade may not be the same. So, after the blade is clamped by the manipulator 3 to the clamping rod 9, it will also affect the grinding effect due to the inconsistent contact angle and grinding path between the blade and the grinding wheel 5. So, to avoid this situation, according to the inclination degree of the inclined surface of the trapezoidal blade, the motor six 53 drives the worm 51 to rotate, so that multiple worm wheels 52 rotate simultaneously, then multiple support plates 48 also rotate simultaneously, making the support plates 48 parallel to the inclined surface of the blade in a vertical state. And, the cylinder five 54 drives the transmission plate 50 to slide on the tray 4 to adjust the distance between the support plate 48 and one side inside the placement grid 47, so that when the inclined surface of the blade fits the surface of the support plate 48, the end face with the largest area of the blade also fits one side end face of the inner cavity of the placement grid 47. When the blade falls to the detection plate 22, it will first be blocked by the support block 35. At this time, according to the width of the blade,By means of driving the rotation of the screw rod three 41 by the motor five 40, the threaded block 43 moves up and down, and the connecting rod 46 is used to drive the adjusting rod 44 to slide on the fixed rod 42, so as to adjust the distance between the two pressure sensors 45, align the pressure sensors 45 with the two side edges of the blade. Then, the cylinder four 39 is used to drive the fixed rod 42 to move, so that the pressure sensors 45 approach the blade until the pressure sensors 45 detect pressure. Since the blade on the detection plate 22 can only be in two states at this time, one is that the end face with the largest area approaches the pressure sensor 45, and the other is that the end face opposite to the end face with the largest area approaches the pressure sensor 45. When the end face with the largest area approaches the pressure sensor 45, the pressure sensor 45 will detect pressure first. On the contrary, the pressure sensor 45 will detect pressure later due to contacting with the inclined surface of the blade. Thus, it can be judged what orientation the blade is in at this time. Then, the feeding plate 20 is driven to rotate 180 degrees by the motor two 18 to adjust the orientation of the blade. Then, the support block 35 is driven to move by the cylinder three 36, so that the support block 35 no longer blocks the bottom of the blade, and the blade falls into the placement grid 47. And the inclined surface of the blade falling into the placement grid 47 fits with the support plate 48, and the end face with the largest area fits with the inner end face of the placement grid 47, and is placed vertically in the placement grid 47. Then, the above operations are repeated, and all the blades can be uniformly oriented and vertically placed in the placement grid 47. Then, the manipulator 3 sequentially clamps multiple blades to the clamping rod 9, and then drives the two clamping rods 9 to approach each other to clamp the trapezoidal blade. Then, the grinding wheel 5 is driven to rotate, and by driving the sliding of the chute plate 12 at the slide rail 13 and the sliding of the mounting plate 11 at the chute plate 12, the position of the grinding wheel 5 in the X and Y axis directions is adjusted. By driving the rotation of the A-axis plate 7 on the base 2 and the rotation of the B-axis plate 8 on the A-axis plate 7, the two clamping rods 9 rotate simultaneously, and the angle of the trapezoidal blade can be adjusted, so that any position of the trapezoidal blade can contact the end face or the outer ring of the grinding wheel 5 and perform grinding work. Since the grinding wheel 5 will gradually wear during use, resulting in a decline in grinding performance, the grinding wheel 5 can be trimmed by driving the dressing disc 14 to rotate, and the outer ring and the end face of the grinding wheel 5 are trimmed by the dressing disc 14, so as to restore its grinding ability, extend the service life of the grinding wheel and improve the grinding efficiency.
