[0002] During the machining of cylinder seat parts, residual contaminants and burrs in their internal cavities require polishing and cleaning. Automated cleaning after polishing has been a persistent challenge in the industry. In existing cylinder seat parts manufacturing processes, after polishing, the parts need to be removed from the polishing fixture and transferred to the cleaning process. Traditional cleaning methods involve manual immersion, requiring repeated shaking of the cylinder seat parts immersed in the cleaning solution and cleaning the holes with a water gun. After basic cleaning, manual cleaning of the workpiece surface and internal holes is still required. The entire cleaning process is time-consuming and labor-intensive, and there is a risk of incomplete cleaning due to human error.

[0003] Therefore, there is a need to provide an apparatus for abrasive flow polishing and cleaning of cylinder seat-type parts to solve the above problems. Summary of the Invention

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] An embodiment of the apparatus for abrasive flow polishing and cleaning of cylinder seat-type parts according to the present invention, such as... Figure 1 , Figure 2 As shown, the device comprises three main parts: a hydraulic clamping assembly 1, a feeding and liquid supply assembly 2, and a frame assembly 3. The hydraulic clamping assembly 1 is located at the top of the device, on which cylinder seat-like parts 4 to be ground, polished, and cleaned are fixedly mounted. The clamping base plate 11 of the hydraulic clamping assembly 1 has channels for the inlet and outlet of the abrasive flow and cleaning fluid. The feeding and liquid supply assembly 2 is located below the hydraulic clamping assembly 1. The feeding and liquid supply assembly 2 is externally connected to the abrasive flow equipment and the cleaning equipment, and it has inlet and outlet channels for the abrasive flow and the cleaning fluid. The frame assembly 3 is located at the bottom of the entire device, which both fixes and supports the hydraulic clamping assembly 1 and can be lowered and moved horizontally to support the feeding and liquid supply assembly 2. The feeding and liquid supply assembly 2 is moved by the frame assembly 3, enabling the plugs of the abrasive flow channel and the cleaning fluid channel on the feeding and liquid supply assembly 2 to switch and connect with the hydraulic clamping assembly 1, that is, to the socket at the bottom of the clamping base plate 11, thus connecting the channel inside the clamping base plate 11, thereby allowing the abrasive flow or cleaning fluid to enter the inner cavity of the cylinder seat part 4 for grinding or cleaning. This invention realizes the automatic cleaning of the cylinder seat part 4, and can complete both abrasive flow grinding and cleaning processes in a single clamping. The technical solution of this embodiment is described in detail below.

[0044] like Figure 3 As shown, the hydraulic clamping assembly 1 mainly includes a clamping base plate 11, a positioning seat 12, and a hydraulic clamping mechanism 13. The positioning seat 12 and the hydraulic clamping mechanism 13 are mounted on the clamping base plate 11. The positioning seat 12 is fixedly installed at the center position of the clamping base plate 11. The positioning seat 12 is designed according to the specific structural shape of cylinder seat-type parts, and its main body is ring-shaped. The positioning seat 12 is used to position and install cylinder seat-type parts 4. The cylinder seat-type parts 4 are installed on the positioning seat 12 and clamped by the hydraulic clamping mechanism 13. The hydraulic clamping mechanism 13 includes an outer ring hydraulic clamp 13-1 and an inner ring hydraulic clamp 13-2. Five outer ring hydraulic clamps 13-1 are evenly distributed around the outer ring of the part to be processed. The outer ring hydraulic clamps 13-1 clamp the outer ring of the part. The inner ring hydraulic clamps 13-2 are located inside the ring of the positioning seat 12. They are provided with three clamping claws evenly distributed around the ring. The inner ring hydraulic clamps 13-2 clamp the inner ring of the part. The hydraulic clamping mechanism 13 evenly clamps the cylinder seat part 4 installed on the positioning seat 12.

[0045] like Figure 2 As shown, the fixture base plate 11 is divided into four different horizontal levels from bottom to top (i.e. Figure 2The hydraulic clamping oil passage layer a, the hydraulic releasing oil passage layer b, the feeding layer passage layer c, and the discharging layer passage layer d) shown are respectively equipped with hydraulic clamping oil passage 11-7, hydraulic releasing oil passage 11-8, feeding layer passage 11-1, and discharging layer passage 11-2. See also... Figure 5 The channels in each layer are arranged in a crisscross pattern within their respective planes, without interfering with each other. The hydraulic clamping oil channel 11-7 and the hydraulic releasing oil channel 11-8 serve as oil circuits, supplying and returning oil to the hydraulic clamping mechanism 13 to achieve clamping and loosening of the parts. The feed layer channel 11-1 and the discharge layer channel 11-2 serve as flow channels for abrasive flow and cleaning fluid. During part grinding and polishing, they are used for abrasive flow feeding and return; during part cleaning, they are used for cleaning fluid feeding and return. To accommodate the channels in each layer, corresponding holes connecting to each channel are provided on the bottom and top surfaces of the fixture base plate 11 to facilitate the flow of hydraulic oil, abrasive flow, and cleaning fluid. To ensure that each channel forms a closed inner cavity, the openings of the clamp base plate 11 of each channel are sealed. Specifically, plugs 14 are installed at each opening of the feed channel 11-1 and the discharge channel 11-2 located on the side wall of the clamp base plate 11. Plugs of the corresponding specifications are also installed at each opening of the hydraulic clamping oil channel 11-7 and the hydraulic releasing oil channel 11-8 located on the side wall of the clamp base plate 11.

[0046] like Figure 4 - Figure 12As shown, the bottom surface of the fixture base plate 11 is perpendicular to the fixture base plate 11 and is provided with a feed hole 11-3, a first return hole 11-4, an oil inlet hole 11-9, and a first oil return hole 11-10. Among them, the feed hole 11-3 is connected to the feed layer channel 11-1, the first return hole 11-4 is connected to the discharge layer channel 11-2, the oil inlet hole 11-9 is connected to the hydraulic clamping oil circuit channel 11-7, and the first oil return hole 11-10 is connected to the hydraulic releasing oil circuit channel 11-8. The top surface of the fixture base plate 11 is provided with two discharge holes 11-5, two second return holes 11-6, six oil outlet holes 11-11 and five second oil return holes 11-12, which are perpendicular to the fixture base plate 11. Among them, the discharge holes 11-5 are connected to the feed layer channel 11-1, the second return holes 11-6 are connected to the discharge layer channel 11-2, the oil outlet holes 11-11 are connected to the hydraulic pressing oil circuit channel 11-7, and the second oil return holes 11-12 are connected to the hydraulic releasing oil circuit channel 11-8. The outward openings of the two discharge holes 11-5 are connected to the inlets of the two corresponding positioning seat feed holes 12-1 on the positioning seat 12. The outward openings of the two second return holes 11-6 are connected to the inlets of the two corresponding positioning seat return holes 12-2 on the positioning seat 12. The outlet ends of the two positioning seat feed holes 12-1 and the two positioning seat return holes 12-2 face the inner cavity of the workpiece being processed. (For ease of description, the opening of the positioning seat feed hole 12-1 facing the end of the fixture base plate 11 is defined as its inlet, and the opening of the other end facing the inner cavity of the workpiece is defined as its outlet. Similarly, the opening of the positioning seat return hole 12-2 facing the end of the fixture base plate 11 is defined as its inlet, and the opening of the other end facing the inner cavity of the workpiece is defined as its outlet. In use, the outlet of the positioning seat return hole 12-2 is actually its inlet when returning material.) Oil outlet 11-11 and second return oil hole 11-12 are combined to form five groups, which are respectively connected to five outer ring hydraulic clamps 13-1 to supply oil to the five outer ring hydraulic clamps 13-1. One oil outlet 11-11 supplies oil to the inner ring hydraulic clamp 13-2. The inner ring hydraulic clamp 13-2 adopts spring relaxation, and hydraulic oil is only supplied when clamping.

[0047] This allows the abrasive or cleaning fluid entering the fixture base plate 11 through the feed hole 11-3, flowing through the feed layer channel 11-1, then exiting the fixture base plate 11 through the two discharge holes 11-5, and then flowing through the two positioning seat feed through holes 12-1 into the inner cavity of the cylinder seat part 4 for grinding, polishing, or cleaning. After the work is completed, the abrasive or cleaning fluid entering the inner cavity of the cylinder seat part 4 enters the two second return holes 11-6 of the fixture base plate 11 through the two positioning seat return through holes 12-2, then enters the discharge layer channel 11-2, and finally flows out through the first return hole 11-4.

[0048] like Figure 6As shown, a central positioning hole 11-13 is provided at the center of the top surface of the fixture base plate 11, with the central positioning hole 11-13 as the positioning center for mounting the remaining parts on the fixture base plate 11. A circular positioning seat mounting hole 11-15 is also provided on the top surface of the fixture base plate 11, for mounting the positioning seat 12. The positioning seat 12 and the central positioning hole 11-13 are coaxial. An angular positioning hole 11-14 is provided on the top surface of the fixture base plate 11 for mounting positioning pins to achieve angular positioning of the workpiece to be processed. Five sets (four in each set) of hydraulic clamping mechanism mounting holes 11-16 are provided around the outside of the positioning seat 12 on the top surface of the fixture base plate 11 for mounting the outer ring hydraulic clamping device 13-1. Three sets (two in each set) of hydraulic clamping mechanism mounting holes 11-16 are provided inside the positioning seat 12 on the top surface of the fixture base plate 11 for mounting the inner ring hydraulic clamping device 13-2. The fixture base plate 11 has four screw holes 11-7 around its circumference for mounting screws 17 to pass through, thereby achieving a fixed connection between the fixture base plate 11 and the frame assembly 3.

[0049] The feeding and liquid supply assembly 2 is located below the hydraulic clamping assembly. The feeding and liquid supply assembly 2 is connected to the abrasive flow equipment and the cleaning equipment through a hose. It has connected the abrasive flow source and the cleaning liquid source to supply abrasive flow or cleaning liquid to the fixture base plate 11. When the parts are polished, the abrasive flow feeding connector of the feeding and liquid supply assembly 2 is connected to the feed hole 11-3 and the first return hole 11-4 to supply and return abrasive flow. When the parts are cleaned, the feeding and liquid supply assembly 2 is switched to the cleaning liquid feeding connector by moving to connect to the feed hole 11-3 and the first return hole 11-4 to supply and return cleaning liquid.

[0050] Specifically, the liquid supply assembly 2 includes a liquid supply plate 21, which is provided with an abrasive flow inlet channel, an abrasive flow return channel, a cleaning fluid inlet channel, a cleaning fluid return channel, and two sets of oil supply channels. The inlet 21-1 of the abrasive flow inlet channel and the outlet 21-4 of the abrasive flow return channel are both equipped with a first hose connector 23. The abrasive flow inlet channel and the abrasive flow return channel are connected to the abrasive flow pump station of the abrasive flow equipment through the first hose connector 23. Both the outlet 21-2 of the abrasive flow inlet channel and the inlet 21-3 of the abrasive flow return channel are equipped with first quick-connect plugs 22. The openings of the feed hole 11-3 and the first return hole 11-4 on the bottom surface of the fixture base plate 11 are equipped with first quick-connect sockets 15. When grinding and polishing parts, the first quick-connect plug 22 at the outlet 21-2 of the abrasive flow inlet channel mates with the first quick-connect socket 15 at the opening of the feed hole 11-3, and the first quick-connect plug 22 at the inlet 21-3 of the abrasive flow return channel mates with the first quick-connect socket 15 at the opening of the first return hole 11-4. This allows the abrasive flow in the abrasive flow equipment to enter the fixture base plate 11 through the abrasive flow inlet channel, and the abrasive flow returning from the fixture base plate 11 to re-enter the abrasive flow equipment through the abrasive flow return channel. The inlet 21-5 of the cleaning fluid inlet channel and the outlet 21-8 of the cleaning fluid return channel are also equipped with first hose connectors 23. These connectors connect hoses to the cleaning fluid inlet and return channels, allowing both to be connected to the cleaning fluid hydraulic station of the cleaning equipment. The outlet 21-6 of the cleaning fluid inlet channel and the inlet 21-7 of the cleaning fluid return channel are each equipped with a first quick-connect plug 22. During parts cleaning, the first quick-connect plug 22 at the outlet 21-6 of the cleaning fluid inlet channel mates with the first quick-connect socket 15 at the inlet hole 11-3, and the first quick-connect plug 22 at the inlet 21-7 of the cleaning fluid return channel mates with the first quick-connect socket 15 at the inlet hole 11-4. This allows the cleaning fluid in the cleaning equipment to enter the fixture base plate 11 through the cleaning fluid inlet channel, and the cleaning fluid returning from the fixture base plate 11 to the automatic cleaning equipment through the cleaning fluid return channel. The oil supply channels are used to connect to the oil inlet hole 11-9 and the first oil return hole 11-10 on the bottom surface of the fixture base plate 11, supplying oil to the hydraulic clamping mechanism 13. One set of oil supply channels is used to match the abrasive flow inlet channel and the abrasive flow return channel, while the other set of oil supply channels is used to match the cleaning fluid inlet channel and the cleaning fluid return channel. The oil supply channels include a hydraulic oil inlet channel and a hydraulic oil return channel. The hydraulic oil inlet channel has one inlet and two outlets, while the hydraulic oil return channel has two inlets and one outlet. A second hose connector 25 is installed at both the inlet 21-9 of the hydraulic oil inlet channel and the outlet 21-12 of the hydraulic oil return channel. The second hose connector 25 connects to the corresponding hose, enabling both the hydraulic oil inlet channel and the hydraulic oil return channel to be connected to the hydraulic oil station.The hydraulic oil inlet channel outlet 21-10 and the hydraulic oil return channel inlet 21-11 are both provided in twos. One set of hydraulic oil inlet channel outlet 21-10 and hydraulic oil return channel inlet 21-11 is on a straight line and collinear with the abrasive flow inlet channel outlet 21-2 and abrasive flow return channel inlet 21-3. The other set of hydraulic oil inlet channel outlet 21-10 and hydraulic oil return channel inlet 21-11 is on a straight line and collinear with the cleaning fluid inlet channel outlet 21-6 and cleaning fluid return channel inlet 21-7. The straight line containing the abrasive flow inlet channel outlet 21-2 and abrasive flow return channel inlet 21-3 is parallel to the straight line containing the cleaning fluid inlet channel outlet 21-6 and cleaning fluid return channel inlet 21-7. Both sets of hydraulic oil inlet channel outlets 21-10 and hydraulic oil return channel inlet 21-11 are equipped with second quick-connect plugs 24. Correspondingly, the inlet hole 11-9 and the first return hole 11-10 are equipped with second quick-connect sockets 16. The second quick-connect plug 24 at the hydraulic oil inlet channel outlet 21-10 connects to the second quick-connect socket 16 at the inlet hole 11-9, and the second quick-connect plug 24 at the hydraulic oil return channel inlet 21-11 connects to the second quick-connect socket 16 at the first return hole 11-10, to achieve quick connection of oil supply. The outlet 21-10 of the same set of hydraulic oil inlet channel and the inlet 21-11 of the hydraulic oil return channel simultaneously connect to the inlet hole 11-9 and the first return hole 11-10, respectively. The two sets of oil supply settings ensure the oil pressure requirement of the hydraulic clamping mechanism 13 in both grinding and cleaning working states.

[0051] In this embodiment, both the first quick-connect plug 22 and the second quick-connect plug 24 have a pressure-holding function, which can prevent internal media leakage during operation.

[0052] like Figures 13-19 As shown, the frame assembly 3 is located at the bottom of the entire device, used to fix and support the hydraulic clamping assembly 1, and can be lowered and moved horizontally to support the feeding and liquid supply assembly 2. Specifically, as... Figures 13-19 As shown, the frame assembly 3 includes a support plate 31, a clamp mounting column 32, a lifting cylinder 33, a lifting plate 34, a linear guide rail assembly 35, and a translation drive assembly 36.

[0053] Four clamp mounting posts 32 are provided at the four corners of the support plate 31. The clamp mounting posts 32 are vertically fixed to the support plate 31. The top surface of the clamp mounting posts 32 is provided with threaded holes for screwing in mounting screws 17. The screws 17 also pass through the screw holes 11-7 of the clamp base plate 11, thereby horizontally mounting the clamp base plate 11 onto the clamp mounting posts 32. Two lifting cylinders 33 are installed on the support plate 31. A lifting plate 34 is horizontally installed on the lifting column 33-1 of the lifting cylinder 33. The lifting plate 34 is raised and lowered with the lifting column 33-1 by the two lifting cylinders 33. In order to achieve the stability of the lifting, two guide posts 37 are vertically installed on the support plate 31. The guide posts 37 are inserted into the corresponding through holes on the lifting plate 34 to guide the lifting of the lifting plate 34. Two sets of linear guide rail assemblies 35 are installed on the lifting plate 34. A liquid supply plate 21 is horizontally slidably mounted on the linear guide rail assembly 35. At the same time, a translation drive assembly 36 is installed on the lifting plate 34, which drives the liquid supply plate 21 to move along the linear guide rail. The lifting cylinder 33 drives the lifting plate 34 to rise and fall simultaneously with the liquid supply plate 21.

[0054] Furthermore, the two sets of linear guide rail assemblies 35 are arranged in parallel, with their track direction perpendicular to the straight line where the outlet 21-2 of the abrasive flow inlet channel and the inlet 21-3 of the abrasive flow return channel are located. The guide rail assembly 35 includes a slider 35-1 and a guide rail 35-2. The guide rail 35-2 is fixedly installed on the lifting plate 34, and the slider 35-1 is slidably installed on the guide rail 35-2. The bottom surface of the liquid supply plate 21 and the upper end surface of the slider 35-1 are in contact and are fixedly connected. The translation drive assembly 36 is a ball screw and servo motor assembly, including a servo motor 36-1, a servo motor mount 36-2, a coupling 36-3, a ball screw rear end mounting base 36-4, a ball screw 36-5, a ball screw nut 36-6, and a ball screw front end mounting base 36-7. The ball screw is mounted on the lifting plate 34 via the ball screw rear end mounting base 36-4 and the ball screw front end mounting base 36-7. The ball screw nut 36-6 can move axially along the ball screw 36-5, and the ball screw 36-5 is parallel to the guide rail assembly 35. The servo motor 36-1 is mounted on the lifting plate 34 via the servo motor mount 36-2, and the output shaft of the servo motor 36-1 is coaxially connected to the ball screw 36-5 via the coupling 36-3. The servo motor 36-1 drives the ball screw 36-5 to rotate, thereby causing the ball screw nut 36-6 to reciprocate axially along the ball screw 36-5. The top surface of the lead screw nut 36-6 contacts the bottom surface of the liquid supply plate 21 and is fixedly connected by fasteners. Therefore, when the servo motor 36-1 works, the liquid supply plate 21 moves axially along the linear guide assembly 35; when the lifting cylinder 33 works, the liquid supply plate 21 is raised or lowered. Four limit blocks 26 are provided on the liquid supply plate 21, which are used to limit the upper and lower movement of the quick-connect plug on the liquid supply plate 21 when it mates with the quick-connect socket at the bottom of the clamp base plate 11.

[0055] The lifting cylinder 33, servo motor 36-1, abrasive flow equipment, automatic cleaning equipment, and hydraulic oil station are all controlled by the control system, which controls their start-up and shutdown. When grinding and polishing of the cylinder seat part 4 to be processed is required, the cylinder seat part 4 to be processed is installed in this device. The control frame assembly 3 drives the liquid supply assembly 2 to lift and move left and right, so that the first quick connector 22 at the outlet 21-2 of the abrasive flow inlet channel on the liquid supply plate 21 and the first quick connector 15 at the opening of the feed hole 11-3 are connected. The first quick connector 22 at the inlet 21-3 of the abrasive flow return channel is connected to the first quick connector 15 at the opening of the first return hole 11-4. At the same time, a set of oil circuit plugs on the liquid supply plate 21 are connected to the two oil holes of the fixture base plate 11. The second quick-connect plug 24 at the outlet 21-10 of the hydraulic oil inlet channel is connected to the second quick-connect socket 16 at the opening of the oil inlet hole 11-9. The second quick-connect plug 24 at the inlet 21-11 of the hydraulic oil return channel is connected to the second quick-connect socket 16 at the opening of the first return hole 11-10. The hydraulic oil station is turned on to realize the hydraulic clamping of the parts. The abrasive flow equipment is turned on to start grinding and polishing, realizing the overall cycle of grinding and polishing of cylinder seat parts. During the cycle, the entire circulation loop cavity is a closed space. The abrasive circulates in the circulation cavity at 2 MPa to realize the grinding and polishing of cylinder seat parts until the grinding and polishing is completed. After grinding and polishing, the abrasive flow equipment feed is shut off, and the hydraulic oil station oil supply is shut off. The fluid supply assembly 2 is driven to rise, fall, and move left and right by the control frame assembly 3. The quick-connect plugs of the fluid supply plate 21 (including the switching between the cleaning fluid plug and the oil circuit plug) are switched, so that the first quick-connect plug 22 at the outlet 21-6 of the cleaning fluid inlet channel aligns with the first quick-connect socket 15 at the opening of the feed hole 11-3, and the first quick-connect plug 22 at the inlet 21-7 of the cleaning fluid return channel aligns with the first quick-connect socket 15 at the opening of the first return hole 11-4. Another set of oil circuit plugs on the fluid supply plate 21 and the fixture base... The two oil holes of plate 11 are connected, that is, the second quick connector 24 at the outlet 21-10 of another hydraulic oil inlet channel is connected to the second quick connector 16 at the opening of the oil inlet 11-9, and the second quick connector 24 at the inlet 21-11 of another hydraulic oil return channel is connected to the second quick connector 16 at the opening of the first return oil hole 11-10. The hydraulic oil station is turned on to realize the hydraulic clamping of the parts, and the automatic cleaning equipment is turned on to start cleaning. Similarly, the entire cleaning cycle is a closed space, and the cleaning pressure is 1 MPa to realize the automated cleaning of the inner cavity of cylinder seat parts until the cleaning is completed. After the cleaning is completed, the control system controls the cleaning equipment to stop, controls the hydraulic oil station to stop the oil supply, the hydraulic clamping mechanism 13 releases the cylinder seat 4, and controls the lifting cylinder 33 to descend to separate the plug on the supply plate 21 from the socket 4 at the bottom of the clamp base plate 11. The cylinder seat 4 is removed, completing the grinding and cleaning process of one cylinder seat 4. Then the grinding and cleaning cycle of the next cylinder seat can be carried out.

[0056] The device for abrasive polishing and cleaning of cylinder seat parts described in this invention integrates hydraulic clamping, abrasive circulation, and online cleaning functions. It can automatically polish and clean cylinder seat parts with abrasive flow in a single clamping operation, thereby improving processing efficiency.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
