DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0031] like Figure 1-12 As shown, a parts cleaning device for mechanical production of the present invention comprises a cleaning box 1, the upper end of the cleaning box 1 is open, vertical plates 101 are fixed on the upper sides of the left and right ends of the cleaning box 1, a U-shaped frame 11 is arranged in the cleaning box 1, the opening of the U-shaped frame 11 faces the front side, and the front end of the U-shaped frame 11 abuts against the inner wall of the cleaning box 1, a flexible filter screen 12 is installed in the opening of the U-shaped frame 11, mounting plates 13 are fixed on the left and right ends of the U-shaped frame 11, and sliding rods 14 are fixed on the front and rear ends of the two mounting plates 13, a vertical slide groove 15 matching the four sliding rods 14 is opened on the side wall of the cleaning box 1, the U-shaped frame 11 is provided with a lifting and flipping mechanism, and a flushing mechanism is arranged on the upper side of the U-shaped frame 11;

[0032] The lifting and flipping mechanism includes two cylinders 2, which are respectively installed in the middle of the left and right sides of the cleaning box 1. A slide groove 21 is opened on the lower side of the two mounting plates 13. A slider 22 is slidably installed in the slide groove 21. A hinge seat 23 is installed on the lower side of the slider 22. The output shaft of the cylinder 2 is hinged to the hinge seat 23. A first arc groove 24 is provided on the rear side of the two vertical plates 101. The lower ends of the two first arc grooves 24 are respectively connected to the upper ends of the two vertical slide grooves 15 on the rear side. A discharge inclined plate 25 is fixed to the front end of the cleaning box 1.

[0033] In the initial state, the slide bar 14 is located at the bottom of the vertical slide groove 15, that is, the U-shaped frame 11 is located inside the cleaning box 1, and the small parts that need to be cleaned are placed in the U-shaped frame 11, and the parts are cleaned by the flushing mechanism. The cleaning liquid for cleaning the parts will enter the bottom of the cleaning box 1 through the filter holes of the flexible filter screen 12. After the parts are cleaned, the cleaned parts are moved out of the cleaning box 1 through the lifting and flipping mechanism, that is, the cylinders 2 installed on both sides of the cleaning box 1 are started, and the cylinders 2 will drive the U-shaped frame 11 to move upward by pushing the mounting plate 13. At this time, the slide bar 14 moves upward in the vertical slide groove 15, and the U-shaped frame 11 will maintain horizontal upward movement. After the slide bar 14 moves to the upper end of the vertical slide groove 15, the flexible filter screen 12 at the bottom of the U-shaped frame 11 passes over the upper end of the cleaning box 1, and the two front slide bars 14 are in the vertical The slide 15 cannot continue to move upward. The first arc groove 24 is set with the axis center when the two front slide bars 14 are located at the uppermost end of the vertical slide 15 as the center. Since the output shaft of the cylinder 2 is hinged with the hinge seat 23 on the slider 22, and the slider 22 is slidably assembled in the slide 21, under the continued push of the cylinder 2, the two rear slide bars 14 will enter the first arc groove 24, and the output shaft of the cylinder 2 will push the slider 22 to move in the slide 21. At this time, the U-shaped frame 11 will turn upward with the axis center of the two front slide bars 14 as the center. In this way, the parts inside the U-shaped frame 11 will roll to the lower end by their own weight. A collection frame can be set at the end of the discharge inclined plate 25. The parts fall downward and enter the collection frame through the discharge inclined plate 25 for collection. The cleaned parts can be automatically unloaded, and the degree of automation is high.

[0034] After the output shaft of the cylinder 2 moves upward to the maximum stroke, the two rear sliding bars 14 will be located at the top of the first arc groove 24. When the output shaft of the cylinder 2 contracts, a downward force is applied to the U-shaped frame 11. At this time, the two rear sliding bars 14 will move downward along the first arc groove 24 until the two rear sliding bars 14 enter the vertical slide groove 15, so that the U-shaped frame 11 is in a horizontal state. The U-shaped frame 11 will move horizontally downward and enter the cleaning box 1 for the next cleaning.

[0035] The present invention can drive the U-shaped frame to move upward and flip through the lifting and flipping mechanism, so that the parts after cleaning will slide onto the discharging inclined plate, and the cleaned parts can be collected uniformly without manual unloading. The whole device has a compact structure and a high degree of automation.

[0036] The flushing mechanism includes a liquid storage tank 3 fixed to the rear side of the cleaning tank 1, a mounting groove 31 is provided at the rear end of the cleaning tank 1, a rotating shaft 32 is rotatably mounted in the mounting groove 31, a flip assembly is provided between the rotating shaft 32 and the U-shaped frame 11, an L-shaped tube 33 is fixed in the middle of the rotating shaft 32, the L-shaped tube 33 extends to the middle of the U-shaped frame 11 and is fixed with a U-shaped frame 34, a nozzle 35 is rotatably mounted in the middle of the U-shaped frame 34, the nozzle 35 is provided with a plurality of evenly distributed nozzles, the middle of the nozzle 35 is connected through a hose L-shaped tube 33, a first motor 36 is provided on one side of the U-shaped frame 34, the output shaft of the first motor 36 is connected to the nozzle 35, a water pump is provided in the liquid storage tank 3, and the liquid outlet end of the water pump is connected to the L-shaped tube 33 through a flexible tube;

[0037] The flip assembly includes a first gear 4 fixed on the left and right sides of the rotating shaft 32, a first rack 41 meshing and matching with the first gear 4 is fixed on the rear side of the U-shaped frame 11, a circular groove 42 is provided at the rear end of the cleaning box 1, and an arc-shaped limit groove 43 is provided on the side wall of the circular groove 42. One end of the rotating shaft 32 extends into the circular groove 42 and is connected to a limit block 44 matching with the arc-shaped limit groove 43. The arc value of the arc-shaped limit groove 43 is greater than π / 2;

[0038] When the U-shaped frame 11 is located inside the cleaning box 1, the nozzle 35 is located in the upper middle part of the U-shaped frame 11. When cleaning parts, the water pump in the liquid storage tank 3 is started to draw the cleaning liquid in the liquid storage tank 3 into the L-shaped tube 33, and then enter the nozzle 35 and spray out through a plurality of nozzles to wash the parts. During the washing process, the first motor 36 can be started to drive the nozzle 35 to rotate back and forth, that is, the spraying angles of the plurality of nozzles are changed, so that the parts in the U-shaped frame 11 can be fully washed to avoid the occurrence of cleaning dead corners;

[0039] When the U-shaped frame 11 is located inside the cleaning box 1, the first rack 41 fixed on the rear side of the U-shaped frame 11 is meshed with the first gear 4, and the limit block 44 is at the front end of the arc-shaped limit groove 43 and is in a horizontal state. When the slide bar 14 of the U-shaped frame 11 moves upward along the vertical slide groove 15, the first rack 41 is driven to move upward. Since the first rack 41 is meshed with the first gear 4, when the first rack 41 moves upward, it will drive the first gear 4 to rotate, thereby driving the rotating shaft 32 in the installation groove 31 to rotate, driving the L-shaped tube 33 to flip backward, so that the nozzle 35 flips backward. In this way, when the U-shaped frame 11 moves upward During the process, the L-shaped tube 33 and the nozzle 35 can be turned backward as a whole, leaving the top of the U-shaped frame 11, and will not cause any obstruction to the U-shaped frame 11. The rotation of the rotating shaft 32 will drive the limit block 44 to rotate in the arc limit groove 43. When the slide bar 14 moves to the upper end of the vertical slide groove 15, the first rack 41 will be disengaged from the first gear 4. At this time, the limit block 44 moves to the rear end of the arc limit groove 43. Since the curvature of the limit arc groove 43 is greater than π / 2, that is, when the limit block 44 is located at the rear end of the arc limit groove 43, the center of gravity of the L-shaped tube 33, the nozzle 35 and other components is facing backward, and will not automatically flip forward.

[0040] When the U-shaped frame 11 is reset, the first rack 41 will mesh with the first gear 4, driving the rotating shaft 32 to flip forward, so that the flushing mechanism is located directly above the U-shaped frame 11, which is convenient for comprehensive flushing of the parts;

[0041] In this way, when the cleaned parts are unloaded, the flushing mechanism located at the upper end of the U-shaped frame 11 can automatically flip backwards to avoid blocking the U-shaped frame 11.

[0042] The left and right walls of the U-shaped frame 11 are both provided with step cavities 111, and slides 112 are slidably provided in the two step cavities 111. The two ends of the flexible filter 12 extend into the two step cavities 111 and are connected to the slides 112 respectively. A rectangular frame 5 is fixed to the bottom of the cleaning box 1 through a bracket, and the upper end of the rectangular frame 5 abuts against the bottom of the U-shaped frame 11. The interior of the rectangular frame 5 is equipped with a plurality of distributed cams 51 through a rotating rod, and the plurality of cams 51 abut against the flexible filter 12, and the orientations of the plurality of cams 51 are not the same. The rear ends of the plurality of rotating rods penetrate the rectangular frame 5 and are connected to sprockets 52, and the plurality of sprockets 52 are connected through chain transmission. A protective shell 54 located outside the plurality of sprockets 52 is fixed to the rear side of the rectangular frame 5, and a second motor 55 is fixed to the rear side of the cleaning box 1. The output shaft of the second motor 55 penetrates the cleaning box 1 and the protective shell 54 and is transmission-connected to one of the sprockets 52.

[0043] When the U-shaped frame 11 is located inside the cleaning chamber 1, the bottom of the U-shaped frame 11 abuts against the rectangular frame 5, and the plurality of cams 51 abut against the flexible filter screen 12. When the flushing mechanism cleans the parts, the second motor 55 fixed to the rear side of the cleaning box 1 is started, and the second motor 55 drives one of the sprocket wheels 52 to rotate. Since the plurality of sprocket wheels 52 are connected by a chain transmission, when one of the sprocket wheels 5 rotates, it will drive the plurality of sprocket wheels 52 to rotate synchronously, thereby making the plurality of cams 51 rotate synchronously. When the raised portion of the cam 51 rotates to the upper side, the middle portion of the flexible filter screen 12 can be lifted upward. The two slides 112 are driven to move closer to the middle part in the step cavity 111, and the flexible filter screen 12 will present a waveform, and some parts will move toward the trough, so that the parts will roll over, so that the parts can be driven to roll over continuously under the rotation of some cams 51, so that the parts can be cleaned comprehensively, and the situation that the parts cannot be cleaned when facing the filter screen side can be avoided; when the flexible filter screen 12 is lifted up by the cam 51, the rear end of the flexible filter screen 12 is always in contact with the rear wall of the U-shaped frame 11, and the front end of the flexible filter screen 12 is always in contact with the front wall of the cleaning box 1, and no gap will appear, so as to prevent the parts from falling off;

[0044] Furthermore, the directions of the cams 51 are all different, so when the cams 51 rotate synchronously, different positions of the flexible filter 12 can be intermittently lifted up to achieve comprehensive turning of the parts on the flexible filter 12, thereby achieving a better cleaning effect.

[0045] A storage box 6 is fixed at the upper end of the two vertical plates 101, and a rectangular discharge pipe 61 is provided at the lower end of the storage box 6. A slot is provided at the front end of the rectangular discharge pipe 61, and a sealing plate 62 is slidably connected in the slot. A connecting strip 63 is fixed at the front end of the sealing plate 62, and a pulling assembly is provided between both ends of the connecting strip 63 and the U-shaped frame 11;

[0046] The pulling assembly includes a second gear 7 rotatably assembled on the side wall of the vertical plate 101, the mounting plate 13 is provided with a through slot 71, and a second rack 72 matching the second gear 7 is provided on the front wall of the through slot 71; the vertical plate 101 is rotatably equipped with a gear ring 73 meshing with the second gear 7, a circular column 74 is rotatably arranged at the center of the gear ring 73, a one-way bearing 741 is arranged between the circular column 74 and the inner wall of the gear ring 73, a winding wheel 75 is installed at the end of the circular column 74, the winding wheel 75 is connected to a pull rope 76, the vertical plate 101 is installed with a fixed pulley 77 located on the upper side of the winding wheel 75, a rectangular plate 78 at the same level as the connecting strip 63 is fixed to the side wall of the vertical plate 101, the rectangular plate 78 is provided with a through hole matching the pull rope 76, the pull rope 76 bypasses the fixed pulley 77 and passes through the through hole to be connected to the connecting strip 63, and a spring 79 is fixed between the connecting strip 63 and the rectangular plate 78.

[0047] The storage box 6 stores small parts that need to be cleaned. The lower end of the second rack 72 is flush with the lower end of the first rack 41. In the initial state, the U-shaped frame 11 is located in the cleaning box 1. At this time, the second rack 72 is not engaged with the second gear 7. When the U-shaped frame 11 moves upward, the second rack 72 will mesh with the second gear 7 to drive the second gear 7 to rotate. Since the ring gear 73 rotatably assembled on the side wall of the vertical plate 101 meshes with the second gear 7, the ring gear 73 can be driven to rotate when the second gear 7 rotates. Since a one-way bearing 741 is provided between the ring gear 73 and the circular column 74, that is, the outer ring of the one-way bearing 741 is connected to the inner wall of the ring gear 73, and the inner ring of the one-way bearing 741 is connected to the outer wall of the circular column 74, When the second gear 71 is disengaged from the second gear 71, the two gears will not collide during the turning process of the U-shaped frame 11. The through groove 71 on the mounting plate 13 is used to increase the space for the second gear 71 and the gear ring 73 during the turning process. The diameter of the gear ring 73 is smaller than that of the second gear 71, so the gear ring 73 will not mesh with the second gear 72.

[0048] After the cleaning parts in the U-shaped frame 11 are dumped, the U-shaped frame 11 will return to the horizontal state and move downward along the vertical slide groove 15. When the U-shaped frame 11 moves vertically downward, the second rack 72 will mesh with the second gear 7, driving the second gear 7 to rotate in the opposite direction, thereby driving the ring gear 73 to rotate in the opposite direction. At this time, the one-way bearing 741 rotates in the opposite direction, and the direction locking will drive the circular column 74 to rotate, so that the reel 75 rotates to reel in the pull rope 76, and the pull rope 76 will pull the connecting strip 63 to move forward, driving the sealing plate 62 to gradually move out of the rectangular discharge pipe 61, and the parts in the storage box 6 will fall downward through the rectangular discharge pipe 61 onto the flexible filter screen 12 to realize automatic unloading. When the slide bar 14 moves to the lower end of the vertical slide groove 15, the second rack 72 is disengaged from the second gear 7, and under the reset elastic force of the spring 79, the sealing plate 62 will be pushed to block the rectangular discharge pipe 61;

[0049] This design eliminates the need for manual placement of parts into the cleaning equipment, simplifies the process, and enables automated cleaning of parts.

[0051] In the initial state, the guide plate 82 is in contact with the bottom of the rectangular discharge tube 61. When the sealing plate 62 moves forward, the connecting strip 63 will drive the straight plate 84 to move forward, and the guide block 86 will enter the second arc groove 852 from the upper straight groove 851. Since the second arc groove 852 is set with the axis of the circular shaft 81 as the center of the circle, the guide block 86 moves from the upper end of the second arc groove 852 to the lower end of the second arc groove 852 during the continuous forward movement of the straight plate 84, and the circular shaft 81 is driven to rotate through the connecting rod 83, thereby driving the guide plate 82 is flipped downward, and the straight plate 84 continues to move forward, and the guide block 86 moves along the lower straight groove 853, so that the guide plate 82 maintains the flip angle, so that the parts in the storage box 6 fall downward from the rectangular discharge pipe 61, and the guide plate 82 flipped at a certain angle guides the parts so that they can accurately fall to the middle of the flexible filter screen 12, and at the same time play a buffering role for the parts, avoiding the distance between the rectangular discharge pipe 61 and the U-shaped frame 11 to be too high, and avoiding the situation where the parts are damaged by a large impact during the downward falling process;

[0052] The parts discharged through the guide plate 82 will be accumulated in the middle of the flexible filter screen 12, and the flexible filter screen 12 will present a wave shape through the rotation of the cams 51, so as to spread out the parts and avoid the situation that the parts are accumulated and cause poor cleaning effect;

[0053] When the sealing plate 62 moves backward to block the rectangular discharge pipe 61, the straight plate 84 will move backward, that is, the guide block 86 will move along the lower straight groove 853 to the second arc groove 852. During this process, the guide plate 82 remains stationary, and when the guide block 86 moves from the lower end to the upper end of the second arc groove 852, the connecting rod 83 drives the circle 81 to rotate in the opposite direction, that is, drives the guide plate 82 to gradually flip upward until it abuts against the lower end of the rectangular discharge pipe 61, and finally the guide block 86 enters the upper vertical groove 851. This design can drive the guide plate 82 to flip during the opening of the sealing plate 62 to guide the parts. When no material is discharged, the guide plate 82 abuts against the lower end of the rectangular discharge pipe 61, which will not affect the flipping of the U-shaped frame 11.

[0054] A drain pipe 9 is provided at the bottom of the cleaning box 1 ; waste liquid from cleaning parts will be discharged from the cleaning box 1 through the drain pipe 9 .
