Description

Technical Field

[0001] The present invention relates to the technical field of engine block cleaning, and specifically to a workpiece clamping and flipping mechanism and a surge cleaning device including the same. Background Art

[0002] During the production or recycling process of an automobile engine block, a cleaning and processing technology for the block is involved. The existing technology for cleaning the block is to transport the block to an assembly line, move the block to a cleaning station, and at the cleaning station, multiple spray heads move to the hole positions or surfaces of the block to perform spray rinsing on the block. After the spray rinsing is completed, the assembly line transfers the block to the next station. The spray rinsing method is prone to cleaning dead spots, resulting in incomplete cleaning. At the same time, the spraying process is long, and it is easy to cause waste of cleaning liquid. In addition, during the cleaning process of the engine block, a fixture is required to fix and limit the position. The existing fixture limiting technologies include manually fixing the fixture by humans or clamping and fixing the workpiece by multiple electric / pneumatic fixtures. The manual method has low positioning efficiency of the workpiece, and the process of taking and placing the fixture is cumbersome; the electric / pneumatic method is prone to failure because the electrical components and pneumatic components used need to be soaked in spray for a long time, and the subsequent maintenance and calibration process of the fixture components is cumbersome and time-consuming.

[0003] Therefore, a device for flipping and cleaning the block by immersing it in a cleaning liquid is needed to increase the cleaning area of the block, improve the cleaning efficiency and quality, and reduce the waste of cleaning liquid. Correspondingly, a workpiece clamping and flipping mechanism should also be provided to quickly clamp and fix the block, and ensure that the clamping function of the block is reliable and does not fail during the flipping and cleaning process, reduce the use of fixture components, and reduce the steps of subsequent maintenance and calibration. Summary of the Invention

[0004] The technical problem to be solved by the present invention is how to provide a workpiece clamping and flipping mechanism and a surge cleaning device including the same.

[0005] To solve the above problems, the technical solutions adopted by the present invention are as follows: A workpiece clamping and flipping mechanism, which includes: Two oppositely arranged mounting plates; A flipping assembly, which includes a support seat and two connecting plates symmetrically arranged at both ends of the support seat. The connecting plates are rotatably arranged on the mounting plate through a rotating shaft; A flipping drive assembly for driving the rotating shaft to rotate; Two symmetrical pressing plate assemblies, which include a pressing plate shaft arranged on the connecting plate, a guide wheel fixedly arranged at one end of the pressing plate shaft through an outer swing arm, and a pressing plate fixedly arranged at the other end of the pressing plate shaft through an inner swing arm; Two sets of platen driving components, which are detachably connected to the platen shaft. The platen driving components are used to drive the platen shaft to rotate, so that the platen presses the workpiece against and fixes it on the support seat. Two sets of limiting guide rails fixed on the mounting plate, on which guide grooves concentric with the turning shaft are provided. During the process of the platen pressing the workpiece, the guide wheels enter the guide grooves through the through grooves provided on the limiting guide rails. When the turning shaft rotates, the guide wheels move in a circular motion along the guide grooves, so that the relative positions between the guide wheels and the support seat are fixed, and further the platen presses the workpiece against the support seat during rotation.

[0006] As an embodiment of the present invention, the platen driving component includes a pressing shaft rotatably arranged through the mounting plate, a guiding groove opened at one end of the pressing shaft, and a cylinder component connected to the other end of the pressing shaft. The cylinder component is used to drive the pressing shaft to rotate. Two guiding columns are symmetrically arranged at one end of the platen shaft. The two guiding columns are located in the guiding groove, so that when the pressing shaft rotates, it drives the platen shaft to rotate synchronously. The guiding groove is integrally arc-shaped. When the platen presses the workpiece, the guiding groove rotates to be concentric with the turning shaft. When the turning shaft rotates, the guide wheels move in a circular motion along the guide grooves, so that the two guiding columns move in a circular motion synchronous with the guide wheels along the extending direction of the guiding groove.

[0007] As an embodiment of the present invention, the cylinder component includes a shaft handle arranged at the end of the pressing shaft and a pressing cylinder arranged on the mounting plate through a cylinder seat. The cylinder body of the pressing cylinder is hingedly connected to the cylinder seat, and the end of the telescopic rod of the pressing cylinder is hingedly connected to the end of the shaft handle. The telescopic rod is extended and retracted to drive the pressing shaft to rotate.

[0008] As an embodiment of the present invention, the limiting guide rail includes a guide rail disk sleeved on the turning shaft and a guide rail connecting column arranged on one side of the guide rail disk. The guide rail connecting column is used to connect the guide rail disk and the mounting plate. The guide groove is opened on the side of the guide rail disk facing the turning assembly, the through groove is opened at the top of the guide rail disk, and a turning shaft through hole is opened on the guide rail connecting column. A sealing component and a bearing component are correspondingly arranged in the turning shaft through hole for the turning shaft.

[0009] As an embodiment of the present invention, the turning driving component includes a driving gear arranged at the end of the turning shaft, a reduction motor arranged on the mounting plate, and an output gear arranged on the output shaft of the reduction motor. The output gear meshes with the driving gear.

[0010] As an embodiment of the present invention, a locking assembly is further provided on the outer side of the mounting plate. The locking assembly includes a locking cylinder fixedly arranged on the mounting plate through a locking support seat and a lifting plate arranged on the output rod of the locking cylinder. The locking cylinder drives the lifting plate to move up and down in the vertical direction, and a V-shaped convex platform is arranged on the lower end surface of the lifting plate; A clamping block is arranged on the end surface of the driving gear, and a V-shaped groove is formed in the clamping block. The lifting plate descends to enable the V-shaped convex platform to be clamped in the V-shaped groove, thereby locking the driving gear and keeping the support seat in a horizontal state.

[0011] As an embodiment of the present invention, a plurality of pressing blocks and a plurality of pressing plate positioning columns are arranged on the pressing plate, and the pressing blocks and the pressing plate positioning columns are adapted to the contour of the upper end surface of the workpiece; Two positioning plates are detachably arranged on the support seat, the positioning plates correspond to the positions of the pressing plates, and a plurality of supporting blocks and a plurality of positioning columns are arranged on the positioning plates. The supporting blocks and the positioning columns are adapted to the contour of the lower end surface of the workpiece.

[0012] In addition, a surge cleaning device is provided, which includes the aforementioned workpiece clamping and flipping mechanism and a box body. A surge chamber is arranged in the box body, two of the mounting plates are arranged on both sides of the surge chamber, and a water injection assembly and a drainage assembly are arranged in the surge chamber; After the cleaning liquid is injected into the surge chamber through the water injection assembly, the flipping assembly rotates to flip and clean the workpiece; After the workpiece is cleaned, the cleaning liquid is discharged through the drainage assembly; A handling window corresponding to the surge chamber is arranged on the box body for taking and placing the workpiece; A rolling curtain assembly is arranged on the handling window to close the handling window during the cleaning process to prevent the cleaning liquid from overflowing.

[0013] As an embodiment of the present invention, a cleaning hole penetrating up and down corresponding to the workpiece is arranged in the middle of the support seat, so that the bottom of the workpiece is in full contact with the cleaning liquid during the cleaning process. Liquid through holes are arranged on both sides of the bottom of the support seat to reduce the resistance of the liquid acting on the support seat during the flipping process of the support seat.

[0014] As an embodiment of the present invention, the rolling curtain assembly includes a scroll rotatably arranged on the top of the box body, a rolling curtain driving motor arranged on the box body, and a waterproof curtain wound around the scroll. One end of the scroll is connected to the output shaft of the rolling curtain driving motor through a sprocket and chain structure.

[0015] The beneficial effects of adopting the above technical solutions are as follows: The workpiece clamping and flipping mechanism provided by the present invention includes a support base that is flip - installed between two mounting plates and a press plate that can open and close. The press plate is used to press the workpiece against the support base. The press plate, the inner swing arm, the press plate shaft, the outer swing arm, and the guide wheel form an integral body. When the press plate shaft rotates, the guide wheel and the press plate can rotate synchronously. Conversely, when the guide wheel is stationary relative to the connecting plate, the press plate shaft is stationary relative to the connecting plate, and the press plate is also stationary relative to the connecting plate. By using this structure and the limit of the guide wheel by the limit guide rail, during the rotation of the support base, the press plate shaft can always remain stationary relative to the connecting plate. Subsequently, when the support base rotates, the press plate and the support base are relatively stationary, ensuring that the workpiece is always tightly pressed and fixed between the press plate and the support base during flipping. This design is ingenious and reliable, avoiding the process of manually applying a fixture to fix the workpiece on the support base and improving the efficiency of workpiece positioning and clamping. At the same time, after the flipping mechanism of the present invention is applied in the surge cleaning device, the flipping and cleaning operation of the workpiece can be realized. Compared with the conventional horizontal rotary spraying process and the process of cleaning point - by - point using a spray head, the workpiece cleaning area of the surge cleaning device of the present invention is larger and the cleaning efficiency is higher.

Detailed implementation mode

[0035] To make the purpose, technical solution and advantages of the present invention clearer, the present invention will be clearly and completely described below in conjunction with specific embodiments.

[0036] As Figure 1 , Figure 2 and Figure 4 shown, a workpiece clamping and flipping mechanism includes: two oppositely arranged mounting plates 102 (in this embodiment, the space between the two mounting plates 102 is the inner side), a flipping component 200 that is flipped between the two mounting plates 102, a flipping drive component 300 arranged on the outer side of any one of the mounting plates 102, two symmetric pressing plate components 400, two groups of pressing plate drive components 500, and two groups of limit guide rails 600.

[0037] See Figure 2 , Figure 4 and Figure 9 The flipping component 200 includes a support seat 201 and two connecting plates 202 symmetrically arranged at both ends of the support seat 201. The connecting plates 202 are rotatably arranged on the mounting plate 102 through a rotating shaft 305. A rotating shaft through hole 203 corresponding to the rotating shaft 305 is opened on the connecting plate 202. The end of the rotating shaft 305 passes through the rotating shaft through hole 203 and is flange-connected to the connecting plate 202. A pressing plate bushing through hole 204 corresponding to the pressing plate component 400 is opened on the connecting plate 202. A pressing plate bushing 401 is penetrated thereon, and the pressing plate bushing 401 is flange-connected to the connecting plate 202.

[0038] See Figure 7 , the flipping drive component 300 includes a drive gear 304 arranged at the end of the rotating shaft 305, a reduction motor 302 arranged on the mounting plate 102, and an output gear 303 arranged on the output shaft of the reduction motor 302. The output gear 303 meshes with the drive gear 304. In this embodiment, a drive support seat 301 is arranged on the mounting plate 102, and the reduction motor 302 is arranged on the drive support seat 301.

[0039] See Figure 10 and Figure 11, the pressing plate assembly 400 includes a pressing plate shaft 402 rotatably disposed within the pressing plate bushing 401, a guide wheel 405 fixedly provided at one end of the pressing plate shaft 402 through an outer swing arm 404, and a pressing plate 407 fixedly provided at the other end of the pressing plate shaft 402 through an inner swing arm 406.

[0040] See Figures 2 to 5 , the pressing plate driving assembly 500 includes a pressing shaft 502 penetrating and rotatably disposed on the mounting plate 102, a guiding groove 503 formed at one end of the pressing shaft 502, and a cylinder component connected to the other end of the pressing shaft 502. The cylinder component is used to drive the pressing shaft 502 to rotate. In this embodiment, a pressing shaft bushing 501 is penetratingly provided on the mounting plate 102, the pressing shaft 502 is rotatably disposed within the pressing shaft bushing 501, and a sealing ring structure and a bearing for rotational support are provided within the pressing shaft bushing 501 corresponding to the pressing shaft 502.

[0041] For details, see Figure 3 (the state where the pressing plate 407 is flipped to press the workpiece) and Figure 5 (the state after the flipping assembly 200 is about to complete one full rotation, at this time the front guiding post 403 has just entered the guiding groove 503), two guiding posts 403 are symmetrically provided at one end of the pressing plate shaft 402. The two guiding posts are located on the diameter of the cross-section of the pressing plate shaft 402, and the two guiding posts 403 are located within the guiding groove 503, such that when the pressing shaft 502 rotates, it drives the pressing plate shaft 402 to rotate synchronously. See Figure 6 , a boss is provided at the end of the pressing shaft 502 in this embodiment, and a guiding groove 503 is formed on the boss. Both ends of the guiding groove 503 penetrate the boss and are used for the guiding post 403 to enter or leave the guiding groove 503.

[0042] See Figures 6 to 8 , the cylinder component includes a shaft handle 504 provided at the end of the pressing shaft 502 and a pressing cylinder 506 provided on the mounting plate 102 through a cylinder seat 507. The cylinder body of the pressing cylinder 506 is hingedly connected to the cylinder seat 507, and the end of the telescopic rod 505 of the pressing cylinder 506 is hingedly connected to the end of the shaft handle 504. The telescopic rod 505 is extended and retracted to drive the pressing shaft 502 to rotate.

[0043] See Figure 3 , Figure 5 and Figure 6, the limit guide rail 600 includes a guide rail disk 601 sleeved on the turning shaft 305 and a guide rail connecting column 604 arranged on one side of the guide rail disk 601. The guide rail connecting column 604 is used to connect the guide rail disk 601 and the mounting plate 102. A guide rail groove 602 is formed on the side of the guide rail disk 601 facing the turning assembly 200. The guide rail groove 602 is concentric with the turning shaft 305. A through groove 603 is formed at the top of the guide rail disk 601. During the process of the pressing plate 407 pressing the workpiece, the guide wheel 405 enters the guide rail groove 602 through the through groove 603 formed on the limit guide rail 600. When the turning shaft 305 rotates, the guide wheel 405 moves in a circular motion along the guide rail groove 602, so that the relative position between the guide wheel 405 and the support base 201 is fixed. Furthermore, the pressing plate 407 presses the workpiece on the support base 201 during rotation.

[0044] In this embodiment, a turning shaft through hole is formed on the guide rail connecting column 604, and a sealing component and a bearing component are correspondingly arranged in the turning shaft through hole for the turning shaft.

[0045] See Figure 6 , and in combination with Figure 3 and Figure 5 As shown in the figure, the guiding groove 503 is integrally arc-shaped. When the pressing plate 407 presses the workpiece, the guiding groove 503 rotates to be concentric with the turning shaft 305. When the turning shaft 305 rotates, the guide wheel 405 moves in a circular motion along the guide rail groove 602, so that the two guiding columns 403 move in a circular motion synchronously with the guide wheel 405 along the extending direction of the guiding groove 503.

[0046] See Figure 7 , a locking assembly 700 is further arranged on the outer side of the mounting plate 102. The locking assembly 700 includes a locking cylinder 702 fixedly arranged on the mounting plate 102 through a locking support base 701 and a lifting plate 703 arranged on the output rod of the locking cylinder 702. The locking cylinder 702 drives the lifting plate 703 to move up and down in the vertical direction. A V-shaped boss is arranged on the lower end surface of the lifting plate 703. A block 306 is arranged on the end surface of the driving gear 304, and a V-shaped groove is formed on the block 306. The lifting plate 703 descends to make the V-shaped boss be clamped in the V-shaped groove to lock the driving gear 304, so that the support base 201 is kept in a horizontal state.

[0047] See Figure 9 and Figure 10, a number of pressing blocks 408 and a number of pressing plate positioning columns 409 are provided on the pressing plate 407. The pressing blocks 408 and the pressing plate positioning columns 409 are adapted to the contour of the upper end surface of the workpiece. Two positioning plates 205 are detachably provided on the support seat 201. The positioning plates 205 correspond to the position of the pressing plate 407. A number of supporting blocks and a number of positioning columns are provided on the positioning plates 205. The supporting blocks and the positioning columns are adapted to the contour of the lower end surface of the workpiece. The structures of the pressing blocks 408, the pressing plate positioning columns 409, the supporting blocks and the positioning columns are adapted to the hole positions or groove structures on the workpiece, so that the workpiece can be quickly placed at the preset position on the support seat 201, improving the positioning efficiency.

[0048] In this embodiment, after the flipping process is completed, the support seat 201 is in a horizontal state, and the locking assembly 700 locks the driving gear 304. At this time, the position of the guide wheel 405 corresponds to the position of the through groove 603, and the two guide posts 403 are located in the guide groove 503 and abut against the two side walls of the guide groove 503. Rotate the pressing shaft 502 to make the pressing plate shaft 402 rotate under the drive of the two guide posts 403. At this time, the guide wheel 405 rotates away from the guide rail groove 602 through the through groove 603, and the pressing plate 407 rotates away from the workpiece to release the workpiece.

[0049] See Figure 1 and Figures 12 to 14 A surge cleaning device, which includes the above-mentioned workpiece clamping and flipping mechanism and a box body 100. A surge chamber 101 is provided in the box body 100. Two installation plates 102 are provided on both sides of the surge chamber 101. A water injection assembly 1000 and a drainage assembly are provided in the surge chamber 101. After the cleaning liquid is injected into the surge chamber 101 through the water injection assembly 1000, the flipping assembly 200 rotates to flip and clean the workpiece. After the workpiece is cleaned, the cleaning liquid is discharged through the drainage assembly.

[0050] A handling window is provided on the box body 100 corresponding to the surge chamber 101 for a manipulator to enter the surge chamber to pick up and place the workpiece. To cooperate with the picking up and placing of the workpiece, a number of in-place sensors 206 are provided on the support seat 201 to collect the in-place information of the workpiece and determine whether the workpiece is placed in place.

[0051] See Figures 12 to 14 , a rolling curtain assembly is provided on the handling window to close the handling window during the cleaning process to prevent the cleaning liquid from overflowing. The rolling curtain assembly includes a reel 104 rotatably provided on the top of the box body 100, a rolling curtain driving motor 103 provided on the box body 100, and a waterproof curtain 105 wound around the reel 104. One end of the reel 104 is connected to the output shaft of the rolling curtain driving motor 103 through a sprocket and chain structure.

[0052] See Figure 2, Figure 4 and Figure 9 , in this embodiment, a cleaning hole penetrating up and down is provided in the middle of the support base 201 corresponding to the workpiece, so that the bottom of the workpiece is in full contact with the cleaning liquid during the cleaning process. Liquid through holes are provided on both sides of the bottom of the support base 201 to reduce the resistance of the liquid acting on the support base 201 during the flipping process of the support base 201.

[0053] See Figures 15 to 17 , in this embodiment, a plurality of pressure block detection components 800 are provided on the box body 100 corresponding to the surge bin 101. The pressure block detection components 800 include a detection rod 801 telescopically arranged on the box body 100, a detection cap 805 arranged at one end of the detection rod 801, and a proximity sensor 806. A detection rod sliding sleeve 804 is arranged on the box body 100 corresponding to the detection rod 801. The detection rod sliding sleeve 804 penetrates through the box body 100 and is fixed by a bolt assembly. The detection rod 801 is slidably arranged in the detection rod sliding sleeve 804. The proximity sensor 806 corresponds to the detection cap 805 and is used to detect the position information of the detection cap 805 to further judge whether the detection rod 801 is pushed.

[0054] An annular detection rod flange 802 is arranged on the detection rod 801 opposite to the detection rod sliding sleeve 804, and a return compression spring 803 is arranged on the detection rod 801 between the detection rod flange 802 and the detection rod sliding sleeve 804.

[0055] A pressure block mounting hole is arranged on the pressing plate 407 of this embodiment corresponding to the position of the pressure block 408. When the pressing plate 407 is in a vertical state (releasing the workpiece) driven by the pressing plate driving component 500, the detection rod 801 passes through the pressure block mounting hole on the pressing plate 407. If a pressure block 408 is installed in the pressure block mounting hole, the pressure block 408 abuts against the detection rod 801 to push the detection rod 801 to compress the return compression spring 803. At the same time, the detection cap 805 moves away from the proximity sensor 806, and the information that the detection rod 801 is pushed is obtained. If no pressure block 408 is installed in the pressure block mounting hole, the detection rod 801 will not be pushed. In this way, the distribution position of the pressure block 408 on the pressing plate 407 can be judged, and further whether the layout and model of the pressure block 408 are suitable for the workpiece can be judged, playing a role of inspection and warning. At the same time, through the compressed model of the detection rod 801, the information on whether the pressing plate 407 is in a vertical state (releasing the workpiece) can be obtained.

[0056] Furthermore, in order to accurately judge the state information of the pressing plate 407, two in-place sensors are arranged on the outer side of the box body 100 corresponding to the shaft handle 504, which are Figure 18 the first in-place sensor 901 and the second in-place sensor 902 in . When the end of the shaft handle 504 approaches the second in-place sensor 902, the pressing plate 407 is in a horizontal state (pressing the workpiece). When the end of the shaft handle 504 approaches the first in-place sensor 901, the pressing plate 407 is in a vertical state (releasing the workpiece).
