Description

Technical Field

[0001] This invention relates to the field of grinding equipment technology, and in particular to a worktable for intelligent grinding equipment. Background Technology

[0002] In order to prevent the spread of dust generated during grinding and to ensure operational safety and the working environment, intelligent grinding equipment usually installs a protective cover above the workbench and an observation window on the door of the protective cover so that operators can observe the internal grinding conditions in real time.

[0003] In practical use, the large amount of dust and debris generated during workpiece grinding easily adheres to the inside of the observation window. Long-term accumulation will severely obstruct the view and affect the monitoring of the internal working status. Currently, the cleaning of the observation window is mostly done by manual wiping or brushing: manual cleaning is inefficient and requires machine downtime, affecting the continuity of processing; although brushing can achieve a certain degree of automatic cleaning, the direct friction between the brush and the observation window can easily cause scratches and wear on the surface of the observation window with long-term use, reducing transparency and service life; at the same time, the brush itself easily adheres to dust and debris during the brushing process, which is difficult to remove on its own, resulting in a gradual decline in cleaning effect and making it impossible to maintain a good observation field of view for a long time.

[0018] The positive and progressive effects of this invention are as follows:

[0019] The aforementioned intelligent grinding equipment workbench, by installing a movable air blower cover inside the observation window, uses airflow to perform non-contact cleaning of the observation window. This effectively removes dust and debris adhering to the observation window, ensuring that operators can clearly observe the grinding process inside the protective cover. It also prevents dust from obstructing monitoring. The air-blowing cleaning method eliminates the need for contact parts such as brushes, avoiding surface scratches and wear caused by direct friction with the observation window, thus extending the service life of the observation window. It also avoids the problem of dust adhering to the brush and causing secondary contamination of the observation window, resulting in a more stable and reliable cleaning effect.

[0020] By setting up a flip-adjustment mechanism, the blowing direction can be automatically adjusted during the movement of the blower baffle, so that the blowing direction is always consistent with the movement direction of the blower baffle. This can push dirt to the uncleaned area in a unified manner, and complete efficient cleaning with a single movement without the need for a reset, thus greatly improving cleaning efficiency.

[0021] The adjustment of the blowing direction relies on the mechanical pressing of the first and second stops, combined with gears, racks, self-locking parts, and unlocking parts to achieve automatic flipping and reset. No additional power components such as motors and cylinders are required throughout the process, nor is any electronic control program involved in the control.

[0022] The air supply mechanism uses a pressure bar and an air cylinder to automatically generate airflow. It utilizes the squeezing action of the moving air blower cover to achieve automatic air supply, eliminating the need for an external air source or power device. Movement and air supply are synchronized, ensuring uninterrupted blowing and reducing device costs. Attached Figure Description

Detailed Implementation

[0041] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0042] like Figures 1-16 As shown, the intelligent grinding equipment workbench includes a table body 1; a protective cover 2 is installed on the top of the table body 1, and a grinding mechanism 7 is provided inside the protective cover 2.

[0043] The protective cover 2 has an entrance and exit on one side, and a door 3 is provided at the entrance and exit, and an observation window 4 is provided on the door 3; the observation window 4 can be made of transparent glass.

[0044] The observation window 4 is provided with a blower strip cover 9 on one side inside the protective cover 2, and a blower nozzle 901 for blowing air to clean the observation window 4 is provided on one side of the blower strip cover 9; a translation mechanism 8 is connected to the top of the blower strip cover 9.

[0045] The bottom of the blower cover 9 is connected to a flip-adjustment mechanism 16 and an air supply mechanism 10; the flip-adjustment mechanism 16 is used to drive the blower cover 9 to flip so that the blowing direction of the blower cover 9 is consistent with the movement direction of the blower cover 9.

[0046] The workpiece is placed inside the protective cover 2 for grinding operations to prevent the spread of grinding dust and thus avoid injury to the operator. An entrance / exit is used for the workpiece to enter and exit the protective cover 2. A door 3 is provided to control the opening and closing of the entrance / exit, and an observation window 4 on the door 3 allows the operator to easily observe the interior of the protective cover 2.

[0047] During polishing, dust or debris generated accumulates on one side of the observation window 4 inside the protective cover 2. The translation mechanism 8 moves the air blower cover 9 horizontally, allowing it to pass over all parts of the observation window 4. Air is supplied to the air blower cover 9 by the air supply mechanism 10, and the air outlet 901 blows air onto the observation window 4, removing the attached debris and dust to ensure effective observation. This air-blowing cleaning method avoids friction with the observation window 4, preventing wear and tear.

[0048] When cleaning the observation window 4 once (during the single cleaning process, the blower cover 9 is moved from one side of the observation window 4 to the other side, such as from the position near the first stop 13 to the second stop 14, or from the position near the second stop 14 to the first stop 13), by setting the flip adjustment mechanism 16, the blowing direction of the blower cover 9 is consistent with the direction of movement, so that the dirt on the observation window 4 can be blown away to the area of ​​the blower cover 9 that has not been cleaned by the airflow.

[0049] In existing technologies, a fixed airflow direction (orientation of the air outlet 901) is used. Airflow cleaning only occurs when the movement direction of the air blower cover 9 is consistent with the airflow direction; otherwise, the air blower cover 9 does not blow air. For example, if the airflow direction of the air blower cover 9 is consistent with the direction in which it moves from the first stop 13 to the second stop 14, the air blower cover 9 moves from the first stop 13 to the second stop 14 and blows air; otherwise, it does not blow air (it only blows air when the air blower cover 9 returns to the first stop 13 and then moves from the first stop 13 to the second stop 14; otherwise, if the movement direction is inconsistent with the airflow direction, dirt will be blown towards the cleaned area of ​​the observation window 4, affecting the airflow cleaning effect). In the above-mentioned existing technology, the air blower cover 9 needs to return to its original position, which affects the cleaning efficiency.

[0050] In specific implementation, a vacuum cleaner 5 is also included; the vacuum cleaner 5 has a suction port connected to a suction pipe 501, which is connected to an interface 201 located on the top of the protective cover 2. During polishing, the vacuum cleaner 5 vacuums up dust, and the dust inside the protective cover 2 enters the vacuum cleaner 5 through the interface 201 and the suction pipe 501, reducing the dust inside the protective cover 2.

[0051] like Figures 2-4 As shown, the grinding mechanism 7 includes a three-axis adjustment assembly; the three-axis adjustment mechanism is connected to the grinding part.

[0052] The three-axis adjustment assembly includes a second motor 701 fixed to the platform 1 and a first screw 702 rotatably mounted on the platform 1. The output shaft of the second motor 701 is connected to the first screw 702. A first movable seat 703 is threaded onto the first screw 702. A vertical plate 706 is fixed to the top of the first movable seat 703, and a slide 705 is fixed to the bottom of the vertical plate 706. The slide 705 is slidably connected to a first guide rail 704 fixed to the platform 1. A third screw 718 is rotatably mounted on the top of the vertical plate 706. A sixth motor 717 is fixed to one side of the top of the vertical plate 706. The output shaft of the sixth motor 717 is connected to the third screw. A third screw 718 is threadedly connected to a second movable seat 707. The second movable seat 707 is slidably connected to a third guide rail 719 fixed to the top of the upright plate 706. A frame 708 is fixed to one side of the second movable seat 707. A third motor 710 is fixed to the top of the frame 708. A second screw 711 is rotatably installed inside the frame 708. The second screw 711 is threadedly connected to a third movable seat 712. The third movable seat 712 is slidably connected to a second guide rail 709 fixed inside the frame 708. A connecting post 713 is fixed to one side of the third movable seat 712. A fourth motor 714 is fixed to the connecting post 713.

[0053] The grinding unit includes a fifth motor 715 fixed to the output shaft of the fourth motor 714, and a grinding disc 716 is mounted on the output shaft of the fifth motor 715. The fifth motor 715 drives the grinding disc 716 to rotate, and the workpiece is ground by the grinding disc 716.

[0054] A turntable 6 is rotatably mounted on the top of the platform 1, and a first motor 601 is fixedly installed inside the platform 1. The output shaft of the first motor 601 is connected to the bottom of the turntable 6.

[0055] When grinding a workpiece, the workpiece is placed on a turntable 6. A fixture is installed on the turntable 6 to hold and fix the workpiece. The first motor 601 drives the turntable 6 to rotate, so that the workpiece moves to the grinding mechanism 7 so that the grinding mechanism 7 can grind all parts of the workpiece.

[0056] The three-axis positioning assembly is used to drive the grinding unit to move in the forward, backward, left, right, and up and down directions, allowing the grinding unit to move to different positions on the workpiece for grinding. The specific operation of the three-axis positioning assembly is as follows: the second motor 701 drives the first screw 702 to rotate. Through the threaded transmission between the first screw 702 and the first movable seat 703, and the sliding guidance between the first guide rail 704 and the slide block 705, the structure on the vertical plate 706 moves in the left and right directions. The sixth motor 717 drives the third screw 718 to rotate. Through the threaded transmission between the third screw 718 and the second movable seat 707, and the sliding guidance between the second movable seat 707 and the third guide rail 719, the structure on one side of the second movable seat 707 moves in the forward and backward directions. The third motor 710 drives the second screw 711 to rotate. Through the threaded transmission between the second screw 711 and the third movable seat 712, and the sliding guidance between the third movable seat 712 and the second guide rail 709, the structure on one side of the third movable seat 712 moves up and down, thereby realizing the three-axis positioning of the grinding unit.

[0057] The fourth motor 714 is used to drive the grinding section to rotate, so as to adjust the grinding angle and meet the grinding of different inclined surfaces on the workpiece.

[0058] like Figure 5 As shown, the translation mechanism 8 includes a fourth guide rail 801 fixed to the top of the door body 3. Each end of the fourth guide rail 801 is fixed with an end bracket 802. A fourth screw 803 is rotatably installed between the two end brackets 802. A fourth movable seat 804 is threaded onto the fourth screw 803. The fourth movable seat 804 is rotatably connected to the top of the blower strip cover 9. A seventh motor 805 is fixed to one side of the end bracket 802. The output shaft of the seventh motor 805 is connected to the fourth screw 803.

[0059] When the observation window 4 needs cleaning, the translation mechanism 8 is used to drive the air blower cover 9 to translate, so that the air blower cover 9 moves across various parts of the observation window 4.

[0060] The working process of the translation mechanism 8 is as follows: the seventh motor 805 drives the fourth screw 803 to rotate. Through the threaded transmission between the fourth screw 803 and the fourth movable seat 804, the fourth movable seat 804 slides with the fourth guide rail 801, so that the fourth movable seat 804 drives the blower strip cover 9 to perform translational movement together.

[0061] In practice, the translation mechanism 8 can be installed at the bottom of the door body 3, and the fourth movable seat 804 of the translation mechanism 8 is fixed to the slider 17.

[0062] like Figures 5-6As shown, the top of the blower cover 9 is rotatably connected to the translation mechanism 8, and the bottom of the blower cover 9 is fixedly connected to a rotating tube 15. The rotating tube 15 is connected to the flip-adjustment mechanism 16 and the air supply mechanism 10. It also includes a slider 17. The flip-adjustment mechanism 16 and the air supply mechanism 10 are both connected to the slider 17. The bottom of the door body 3 is fixed with a slide rail 12, and the slide rail 12 is arranged parallel to the translation mechanism 8. The slider 17 is slidably connected to the slide rail 12.

[0063] The translation mechanism 8 drives the air blower cover 9 to move, and the air blower cover 9 drives the flip-adjustment mechanism 16 and the air supply mechanism 10 below it to move together, and the slider 17 provides guidance through the sliding of the slide rail 12.

[0064] like Figure 6 , Figure 12 as well as Figure 13 As shown, the flipping and adjusting mechanism 16 includes a housing 1602 fixed to the slider 17; the housing 1602 is rotatably connected to the rotating tube 15, and a return torsion spring is installed between the housing 1602 and the rotating tube 15; a gear 1605 is fixedly sleeved on the rotating tube 15, the gear 1605 meshes with a rack 1606, and the rack 1606 is slidably installed inside the housing 1602; a first [missing information] is fixedly connected to each side of the housing 1602. Side cover 1603 and second side cover 1604, one end of the rack 1606 is fixed with a pressure strip 1601, the pressure strip 1601 is slidably engaged with a hole provided at one end of the second side cover 1604, the pressure strip 1601 extends to the outside of the end of the second side cover 1604 away from the housing 1602; a stop block 1607 is fixed at the end of the pressure strip 1601 connected to the rack 1606, and a self-locking part 18 is installed on the pressure strip 1601.

[0065] like Figure 14 and Figure 16 As shown, the self-locking part 18 includes a locking block 1802 and a guide post 1801; the pressure bar 1601 has an inner cavity 16011 inside, and the outer wall of the pressure bar 1601 has a sliding groove 16012 communicating with the inner cavity 16011. The locking block 1802 is slidably connected to the sliding groove 16012. One end of the locking block 1802 has a first guide groove 1804. The first guide groove 1804 is slidably engaged with the guide post 1801 fixed in the inner cavity 16011. The guide post 1801 and the locking block 1802 are elastically connected by a second spring 1805.

[0066] The locking block 1802 has a second inclined surface 1803 at one end away from the first guide groove 1804, and the outer side of the hole on the second side cover 1604 has a first inclined surface 16041 adapted to the second inclined surface 1803.

[0067] A second stop 14 is fixed to one side of the bottom of the door body 3; the second stop 14 faces the pressure strip 1601.

[0068] like Figures 12-16 As shown, the pressure bar 1601 is also provided with an unlocking part 19, which includes a movable rod 1901. The pressure bar 1601 and the rack 1606 have a second guide groove 1902. The movable rod 1901 slides into the second guide groove 1902. One end of the movable rod 1901 extends beyond the end of the rack 1606 away from the pressure bar 1601, and the other end extends into the inner cavity 16011. A magnetic block 1906 is fixed at one end of the inner cavity 16011. The movable rod 1901 is elastically connected to the side wall of the inner cavity 16011 via a third spring 1905 (a connecting plate 1903 is fixed on the movable rod 1901, a fixing block 1904 is fixed in the inner cavity 16011, and the two ends of the third spring 1905 are fixed to the connecting plate 1903 and the fixing block 1904 respectively, achieving an elastic connection). An iron block 1907 is fixed to one side of the locking block 1802. The magnetic block 1906 is a permanent magnet.

[0069] A first stop 13 is fixed to the bottom of the door body 3 on the side away from the second stop 14, and the first stop 13 faces the movable rod 1901 of the unlocking part 19.

[0070] When the blower cover 9 moves closer to the second stop 14, the blower nozzle 901 of the blower cover 9 faces as follows: Figure 9 As shown, after the pressure strip 1601 and the second stop 14 are attached, as Figure 9 As shown; the subsequent translation mechanism 8 continues to drive the blower strip cover 9 to move closer to the second stop 14. The pressure strip 1601 is blocked and squeezed by the second stop 14, causing the pressure strip 1601 to move into the second side cover 1604. The pressure strip 1601 drives the rack 1606 to move. Through the meshing transmission between the rack 1606 and the gear 1605, the rotating tube 15 and the blower strip cover 9 rotate clockwise together and twist the return spring until they move into place, as shown. Figure 10As shown, at this time, the blower strip cover 9 completes symmetrical adjustment. During the movement of the pressure strip 1601 and rack 1606 together, the stop block 1607 separates from the inner wall of the end of the second side cover 1604 away from the housing 1602. The locking block 1802 moves closer to the second side cover 1604 until it enters the second side cover 1604. The locking block 1802 presses the first inclined surface 16041 through the second inclined surface 1803, causing the locking block 1802 to move into the inner cavity 16011 and compress the second spring 1805. When the locking block 1802 passes through the hole at the end of the second side cover 1604 and enters the second side cover 1604, the locking block 1802 loses its obstruction. The elastic force of the second spring 1805 causes the locking block 1802 to protrude from the slide groove 16012, completing the self-locking. Figures 15-16 When the subsequent translation mechanism 8 drives the blower cover 9 to move closer to the first stop 13, the pressure bar 1601 separates from the second stop 14, and the locking block 1802 fits against the inner wall of the end of the second side cover 1604 to block it, so as to maintain the state of the blower cover 9 after the flip-adjustment mechanism 16 has adjusted it, so that the blower cover 9 remains as it is. Figure 10 The movement moves toward the first stop 13 as shown.

[0071] The first side cover 1603 has a groove at the end away from the housing 1602. After the self-locking is completed, the movable rod 1901 passes through the groove and extends out from the groove.

[0072] After the blower baffle 9 moves closer to the first stop 13, and the movable rod 1901 contacts the first stop 13, as follows: Figure 11 As shown, the blower cover 9 continues to move. The first stop 13 blocks and presses the movable rod 1901. The movable rod 1901 moves relative to the rack 1606 and the pressure bar 1601 and is guided by the second guide groove 1902. The movable rod 1901 drives the magnetic block 1906 to move until it is aligned with the iron block 1907. At the same time, the third spring 1905 is compressed. The magnetic block 1906 magnetically attracts the iron block 1907. The iron block 1907 drives the locking block 1802 to move automatically into the inner cavity 16011. The locking block 1802 does not protrude from the slide groove 16012, and the unlocking is completed. The flipping and adjusting mechanism 16 drives the rotating tube 15 and the blower cover 9 to flip counterclockwise together through the reset torsion spring. The blower cover 9 returns to its original position. Figure 9 As shown, gear 1605 meshes with rack 1606, causing the pressure bar 1601 and rack 1606 to move away from the first stop 13 together, and the pressure bar 1601 returns to its original position. Figure 12 In the state shown, the movable rod 1901 is reset by the elastic force of the third spring 1905, the magnetic block 1906 is separated from the iron block 1907, and the self-locking mechanism is reset by the second spring 1805.

[0073] Through the above design, the air blowing direction of the blower cover 9 is always consistent with the direction of movement, and the flipping and adjustment of the blower cover 9 is achieved by the squeezing of the first stop 13 and the second stop 14, without the need for additional power components and control components to provide power and control, thus achieving automatic adjustment.

[0074] like Figures 6-8 As shown, the air supply mechanism 10 includes a connecting frame 1001 fixed to the slider 17; the connecting frame 1001 is provided with two air cylinder sections, each air cylinder section including a cylinder body 1002 fixed to the connecting frame 1001. A first one-way valve 1010 and a second one-way valve 1011 are installed on the top of the cylinder body 1002. The first one-way valve 1010 is connected to a three-way pipe 1003, the top end of the three-way pipe 1003 is rotatably sleeved with the bottom end of the rotating pipe 15, and a sealing element is provided at the connection point to achieve rotational sealing. The second one-way valve 1011 is connected to an air inlet pipe 1004. The door body 3 has a strip groove 301. The air intake pipe 1004 passes through the strip groove 301 and extends to the outside of the protective cover 2. A piston 1007 is fitted inside the cylinder 1002. A movable column 1005 is fixed to the bottom of the piston 1007, and the movable column 1005 slides in conjunction with a slot at the bottom of the cylinder 1002. The top of the piston 1007 is elastically connected to the inner wall of the top of the cylinder 1002 via a first spring 1008. A roller 1006 is rotatably mounted at the bottom of the movable column 1005, and the roller 1006 abuts against a pressure strip 11 fixed to the bottom of the door body 3. A retaining ring 1009 is fixed inside the top of the cylinder 1002.

[0075] The pressure strip 11 is provided with a plurality of equally spaced protrusions, and the protrusions are isosceles triangular structures; the distance between the two air cylinder parts is half the length of the base of the protrusion.

[0076] The air supply mechanism 10 supplies air to the rotating pipe 15, so that the gas is injected into the blower shroud 9 and then blown out from the blower shroud 9.

[0077] like Figure 8 As shown, the rollers 1006 on the two air cylinders of the air supply mechanism 10 respectively abut against the middle and one side of a protrusion. When the blower cover 9 moves left and right, one roller 1006 will definitely go downhill on one side of the protrusion, and the other roller 1006 will definitely go uphill on one side of the protrusion.

[0078] The roller 1006 moves downhill in the air cylinder section. The piston 1007, the movable column 1005, and the roller 1006 move downward together through the elastic force of the first spring 1008. The roller 1006 always abuts against the pressure bar 11. The cylinder 1002 is evacuated. Air outside the protective cover 2 enters the cylinder 1002 through the air inlet pipe 1004 and the second one-way valve 1011.

[0079] The roller 1006 moves uphill in the air cylinder section, where the roller 1006, movable column 1005, and piston 1007 are squeezed upward together. The piston 1007 pushes the gas in the cylinder 1002, and the gas enters the blower shroud 9 through the first one-way valve 1010, three-way pipe 1003, and rotating pipe 15.

[0080] With the above design, the blower shroud 9 is always supplied with air by an air cylinder while it moves, the blower shroud 9 blows air continuously, and the air supply is powered by the compression of the pressure bar 11, without the need for additional power and control.

The protection scope of this invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this invention, but all such changes and modifications fall within the protection scope of this invention.
