Description

Technical Field

[0001] The present invention relates to the technical field of engine cylinder cleaning, in particular to a workpiece clamping and turning mechanism and a surge cleaning device comprising the same. Background Art

[0002] The production or recycling process of automobile engine cylinders involves a cylinder cleaning process. The existing cylinder cleaning process involves transporting the cylinder to an assembly line, moving the cylinder to a cleaning station, and moving multiple nozzles at the cleaning station to the holes or surface of the cylinder to spray and rinse the cylinder. After the spraying and rinsing is completed, the cylinder is transferred to the next station by the assembly line. The spraying and rinsing method is prone to cleaning dead corners, resulting in incomplete cleaning. At the same time, the spraying process is long and easily wastes cleaning fluid. In addition, the engine cylinder needs to be fixed and limited by a fixture during the cleaning process. The existing fixture limiting technology: either manually fix the fixture or clamp the workpiece with multiple electric / pneumatic fixtures. The manual method has low workpiece positioning efficiency and the fixture placement process is cumbersome. The electric / pneumatic method uses electrical and pneumatic components that need to be sprayed and soaked for a long time, which is prone to failure. The subsequent maintenance and adjustment process of the fixture components is cumbersome and time-consuming.

[0003] Therefore, a device is needed to immerse the cylinder body in cleaning liquid for flipping and cleaning, so as to increase the cleaning area of the cylinder body, improve the cleaning efficiency and quality, and reduce the waste of cleaning liquid. Correspondingly, a workpiece clamping and flipping mechanism should be provided to quickly clamp and fix the cylinder body, and ensure that the clamping function of the cylinder body is reliable and does not fail during the flipping and cleaning process, thereby reducing the use of fixture components and reducing the steps of subsequent maintenance and adjustment.

[0030] As an embodiment of the present invention, the rolling shutter assembly includes a reel rotatably arranged on the top of the box body, a rolling shutter drive motor arranged on the box body, and a waterproof curtain wound around the reel, and one end of the reel is connected to the output shaft of the rolling shutter drive motor through a sprocket chain structure.

[0031] The beneficial effects of adopting the above technical solution are:

[0032] The workpiece clamping and flipping mechanism provided by the present invention includes a flip support seat and a foldable pressure plate arranged between two mounting plates, wherein the pressure plate is used to press the workpiece onto the support seat. The pressure plate, the inner swing arm, the pressure plate shaft, the outer swing arm and the guide wheel form an integral body. When the pressure plate shaft rotates, the guide wheel and the pressure plate can rotate synchronously. On the contrary, when the guide wheel is stationary relative to the connecting plate, the pressure plate shaft is stationary relative to the connecting plate, and the pressure plate is also stationary relative to the connecting plate. By using this structure in conjunction with the limiting guide rail to limit the guide wheel, the pressure plate shaft can always be stationary relative to the connecting plate during the rotation of the support seat. Then, when the support seat rotates, the pressure plate and the support seat are relatively stationary, ensuring that the workpiece is always pressed and fixed between the pressure plate and the support seat during flipping. This design is ingenious and reliable, avoiding the process of manually applying a clamp to fix the workpiece on the support seat, 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 cleaning operation of the workpiece can be realized. Compared with the conventional horizontal rotary spraying process and the point-by-point cleaning process using a nozzle, the workpiece cleaning area of the surge cleaning device of the present invention is larger and the cleaning efficiency is higher.

The output gear 303 meshes with the drive gear 304. In this embodiment, a drive support base 301 is disposed on the mounting plate 102, and the reduction motor 302 is disposed on the drive support base 301.

[0063] See also Figure 10 and Figure 11 The pressure plate assembly 400 includes a pressure plate shaft 402 rotatably arranged in the pressure plate sleeve 401, a guide wheel 405 fixed at one end of the pressure plate shaft 402 through an outer swing arm 404, and a pressure plate 407 fixed at the other end of the pressure plate shaft 402 through an inner swing arm 406.

[0064] See also Figures 2 to 5 The pressure plate drive assembly 500 includes a pressure shaft 502 that extends through and rotatably mounts on the mounting plate 102, a guide groove 503 formed on one end of the pressure shaft 502, and a cylinder component connected to the other end of the pressure shaft 502. The cylinder component is used to rotate the pressure shaft 502. In this embodiment, a pressure shaft sleeve 501 extends through the mounting plate 102, and the pressure shaft 502 is rotatably mounted within the pressure shaft sleeve 501. A sealing ring structure and a bearing for rotational support are disposed within the pressure shaft sleeve 501 corresponding to the pressure shaft 502.

[0065] See Figure 3 (Pressing plate 407 is turned over to press the workpiece) and Figure 5 (The flip assembly 200 is about to complete a full flip, and the front guide post 403 has just entered the guide groove 503.) Two guide posts 403 are symmetrically provided on one end of the pressure plate shaft 402. The two guide posts are located on the diameter of the cross section of the pressure plate shaft 402. The two guide posts 403 are located in the guide groove 503, so that when the pressing shaft 502 rotates, the pressure plate shaft 402 is driven to rotate synchronously. Figure 6In this embodiment, a boss is provided on the end of the clamping shaft 502, and a guide groove 503 is opened on the boss. Both ends of the guide groove 503 pass through the boss, which is used to guide the column 403 to enter or leave the guide groove 503.

[0066] See also Figures 6 to 8 The cylinder component includes a shaft handle 504 provided on the end of the pressing shaft 502 and a pressing cylinder 506 provided on the mounting plate 102 via 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.

[0067] See also Figure 3 、 Figure 5 and Figure 6 The limiting guide rail 600 includes a guide rail disc 601 sleeved on the flip shaft 305 and a guide rail connecting post 604 disposed on one side of the guide rail disc 601. The guide rail connecting post 604 is used to connect the guide rail disc 601 to the mounting plate 102. The guide rail disc 601 has a guide rail groove 602 on the side facing the flip assembly 200. The guide rail groove 602 is concentric with the flip shaft 305. A through groove 603 is defined at the top of the guide rail disc 601. When the pressure plate 407 presses the workpiece, the guide wheel 405 enters the guide rail groove 602 through the through groove 603 defined on the limiting guide rail 600. When the flip 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 seat 201 is fixed, and the pressure plate 407 presses the workpiece onto the support seat 201 during the rotation process.

[0068] In this embodiment, a turning shaft through hole is opened on the guide rail connecting column 604, and a sealing component and a bearing component are provided in the turning shaft through hole corresponding to the turning shaft.

[0069] See also Figure 6 , and combined with Figure 3 and Figure 5 The guide groove 503 is arc-shaped as a whole. When the pressure plate 407 presses the workpiece, the guide groove 503 rotates to be concentric with the flip axis 305. When the flip axis 305 rotates, the guide wheel 405 makes a circular motion along the guide groove 602, so that the two guide columns 403 make a circular motion along the extension direction of the guide groove 503 in synchronization with the guide wheel 405.

[0070] See also Figure 7A locking assembly 700 is also provided on the outside of the mounting plate 102. The locking assembly 700 includes a locking cylinder 702 fixed to the mounting plate 102 via a locking support 701, and a lifting plate 703 mounted on the output rod of the locking cylinder 702. The locking cylinder 702 drives the lifting plate 703 to move vertically up and down. A V-shaped boss is provided on the lower end surface of the lifting plate 703. A clamping block 306 with a V-shaped groove is provided on the end surface of the driving gear 304. The lifting plate 703 descends to engage the V-shaped boss in the V-shaped groove, thereby locking the driving gear 304 and maintaining the support base 201 in a horizontal state.

[0071] See also Figure 9 and Figure 10 The pressure plate 407 is equipped with several pressure blocks 408 and several pressure plate positioning columns 409. These pressure blocks 408 and pressure plate positioning columns 409 match the contour of the upper end face of the workpiece. The support seat 201 is detachably provided with two positioning plates 205. These positioning plates 205 correspond to the positions of the pressure plate 407. These positioning plates 205 are equipped with several support blocks and positioning columns. These support blocks and positioning columns match the contour of the lower end face of the workpiece. The structure of the pressure blocks 408 and pressure plate positioning columns 409, as well as the support blocks and positioning columns, matches the hole or groove structure on the workpiece, allowing the workpiece to be quickly placed in the preset position on the support seat 201, improving positioning efficiency.

[0072] 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 through the groove 603, and the two guide columns 403 are located in the guide groove 503 and are against the two side walls of the guide groove 503. The clamping shaft 502 is rotated to rotate the pressure plate shaft 402 under the drive of the two guide columns 403. At this time, the guide wheel 405 rotates through the groove 603 to leave the guide groove 602, and the pressure plate 407 rotates away from the workpiece to release the workpiece.

[0073] See also Figure 1 as well as Figures 12 to 14 A surge cleaning device includes the aforementioned workpiece clamping and flipping mechanism and a housing 100. A surge chamber 101 is disposed within the housing 100, with two mounting plates 102 disposed on either side of the surge chamber 101. A water injection assembly 1000 and a drainage assembly are also disposed within the surge chamber 101. After cleaning fluid is injected into the surge chamber 101 via the water injection assembly 1000, the flipping assembly 200 rotates to flip the workpiece for cleaning. After the workpiece is cleaned, the cleaning fluid is discharged through the drainage assembly.

[0074] A transport window is provided on the box body 100 corresponding to the surge bin 101, for a robot to enter the surge bin to pick up and place the workpiece. To facilitate the picking up and placing of the workpiece, a plurality 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.

[0075] See also Figures 12 to 14 The transport window is equipped with a roller shutter assembly to seal the window during cleaning to prevent spillage of the cleaning solution. The roller shutter assembly includes a reel 104 rotatably mounted on the top of the housing 100, a roller shutter drive motor 103 mounted on the housing 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 roller shutter drive motor 103 via a sprocket chain structure.

[0076] See also Figure 2 、 Figure 4 and Figure 9 In this embodiment, a cleaning hole is opened in the middle of the support seat 201 corresponding to the workpiece, so that the bottom of the workpiece is fully in contact with the cleaning liquid during the cleaning process. Liquid through holes are provided on both sides of the bottom of the support seat 201 to reduce the resistance of the liquid acting on the support seat 201 during the flipping of the support seat 201.

[0077] See also Figures 15 to 17 In this embodiment, the housing 100 is provided with a plurality of pressure block detection assemblies 800 corresponding to the surge bin 101. These assemblies include a detection rod 801 retractably mounted on the housing 100, a detection cap 805 disposed at one end of the detection rod 801, and a proximity sensor 806. A detection rod sleeve 804 is provided on the housing 100 corresponding to the detection rod 801. The detection rod sleeve 804 extends through the housing 100 and is secured by a bolt assembly. The detection rod 801 is slidably disposed within the detection rod sleeve 804. The proximity sensor 806 corresponds to the detection cap 805 and is used to detect the position of the detection cap 805 and thereby determine whether the detection rod 801 is being pushed.

[0078] An annular detection rod flange 802 is provided on the detection rod 801 opposite to the detection rod sliding sleeve 804 , and a return compression spring 803 is provided on the detection rod 801 between the detection rod flange 802 and the detection rod sliding sleeve 804 .

[0079] In this embodiment, a pressure block mounting hole is provided at the position corresponding to the pressure block 408 on the pressure plate 407. When the pressure plate 407 is in a vertical state (releasing the workpiece) under the drive of the pressure plate driving assembly 500, the detection rod 801 passes through the pressure block mounting hole on the pressure plate 407. If a pressure block 408 is installed in the pressure block mounting hole, the pressure block 408 and the detection rod 801 abut against each other, thereby pushing the detection rod 801 to compress the reset spring 803. At the same time, the detection cap 805 moves away from the proximity sensor 806, and 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 pressure plate 407 can be judged, and then the layout and model of the pressure block 408 can be judged to be compatible with the workpiece, which plays a picket warning role. At the same time, the compressed model of the detection rod 801 can be used to obtain information on whether the pressure plate 407 is in a vertical state (releasing the workpiece).

[0080] Furthermore, in order to accurately determine the status information of the pressure plate 407, two position sensors are provided on the outer side of the box body 100 corresponding to the shaft handle 504, namely Figure 18 In the first in-position sensor 901 and the second in-position sensor 902, when the end of the shaft handle 504 is close to the second in-position sensor 902, the pressure plate 407 is in a horizontal state (pressing the workpiece), and when the end of the shaft handle 504 is close to the first in-position sensor 901, the pressure plate 407 is in a vertical state (releasing the workpiece).
