The ultra-high pressure special-shaped piston is a special structure piston used in ultra-high pressure environments. Its appearance breaks through the traditional cylindrical design and has the characteristics of asymmetry, complex curves, and special geometric contours.

Its unique structure can optimize fluid mechanics properties and improve energy conversion efficiency. It is suitable for high-end equipment fields that have extremely high requirements for piston performance and working environment.

[0003] During the piston processing process, one of the steps requires polishing the piston to ensure its surface is smooth.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] like Figures 1 to 7 As shown, the present invention provides an ultra-high pressure special-shaped piston processing device, including a grinding table 1, and also including: Cylinder 2, cylinder 2 is arranged on the top outer wall of the grinding table 1, and the output shaft of cylinder 2 is provided with a clamping block 4 through a connecting mechanism 3; grinding module 7, grinding module 7 is arranged on the outer wall of the grinding table 1; dust collection module 6, dust collection module 6 is slidably connected to the outer wall of the grinding table 1; collection mechanism 5, collection mechanism 5 is provided on the outer wall of dust collection module 6 through a connecting pipe; Among them, the connecting mechanism 3 includes a mounting block 301, the inner wall of the mounting block 301 is elastically connected to the sliding rod 313 through the elastic member A308; the collecting mechanism 5 includes a waste dust box 501, the inner wall of the waste dust box 501 is fixedly connected to the screen plate 510.

[0020] The above scheme is adopted: the grinding table 1 is a workbench body for grinding ultra-high pressure special-shaped pistons, the grinding module 7 is fixed on the grinding table 1, and the motor in the grinding module 7 can drive the grinding head to grind the top surface of the ultra-high pressure special-shaped piston. The powdery waste generated during the grinding process can be sucked into the collection mechanism 5 by the dust collection module 6 for centralized collection and treatment; the cylinder 2 and the clamping block 4 are each provided with two groups, symmetrically distributed on both sides of the grinding table 1, and the movable end of the cylinder 2 can drive the two groups of clamping blocks 4 to move to both sides or the middle at the same time to clamp and fix the outside of the ultra-high pressure special-shaped piston to prevent it from shifting during the grinding process and affecting the grinding effect; when grinding ultra-high pressure special-shaped pistons of different shapes, the clamping block 4 can be replaced through the connecting mechanism 3 to select the clamping block 4 that is suitable for the piston surface for fixed use, and the disassembly and installation operations are relatively convenient and quick, thereby improving efficiency.

[0021] like Figures 2 to 4 As shown, the movable end of the cylinder 2 is fixedly connected to the connecting block 302, the inner wall of the connecting block 302 is provided with grooves A303 and B304, the inner wall of the mounting block 301 is slidably connected to the shift block 305, the sliding rod 313 is hinged to the outer wall of the shift block 305 through the hinge rod 306, the outer wall of the sliding rod 313 is fixedly connected to the wedge block B307, the outer wall of the sliding rod 313 is fixedly connected to the slider 309, the outer wall of the slider 309 is fixedly connected to the trapezoidal block 310, the inner wall of the mounting block 301 is slidably connected to the guide rod 311, and the inner wall of the mounting block 301 is slidably connected to the wedge block A312.

[0022] With the above solution, when installing the clamping block 4, it can be inserted into the movable end of the cylinder 2 and then inserted into the connecting block 302 through the mounting block 301. The wedge block A312 engages with the groove A303, and the wedge block B307 engages with the groove B304. This limits the position of the clamping block 4 and the movable end of the cylinder 2, so that the clamping block 4 will not be separated from the movable end. When the clamping block 4 needs to be removed, the shifting block 305 can be moved to disengage the wedge block A312 and the wedge block B307 from the groove A303 and the groove B304, respectively, so that the clamping block 4 can be removed. There is no need to turn multiple bolts for disassembly and installation, which saves time and effort. Under normal circumstances, the elastic member A308 causes the sliding rod 313 and the wedge block B307 to be in a certain position due to its own elastic force, and the wedge block B307 is outside the mounting block 301. The sliding rod 313 drives the slider 309 and the trapezoidal block 310 to be in a fixed state. At this time, the guide rods 311 on both sides of the trapezoidal block 310 are in contact with the long side inclined surface of the trapezoidal block 310. The guide rods 311 drive the two groups of wedge blocks A312 to be outside the mounting block 301. The guide rods 311 can only move vertically in the inner wall of the mounting block 301. The arc surfaces of the wedge block A312 and the wedge block B307 are both facing the direction of the connecting block 302.

[0023] like Figures 2 to 4 As shown, the mounting block 301 is fixedly connected to the outer wall of the clamping block 4, the two ends of the hinged rod 306 are hinged to the outer walls of the sliding rod 313 and the shift block 305 respectively, the sliding rod 313 is slidably connected to the inner wall of the mounting block 301, the wedge block A312 is engaged with the groove A303, and the wedge block B307 is engaged with the groove B304; one end of the elastic member A308 is fixedly connected to the outer wall of the sliding rod 313, and the other end of the elastic member A308 is fixedly connected to the inner wall of the mounting block 301, the wedge block A312 and the wedge block B307 are both slidably connected to the inner wall of the mounting block 301, and the slider 309 is slidably connected to the inner wall of the mounting block 301; one end of the guide rod 311 is slidably connected to the outer wall of the trapezoidal block 310, and the other end of the guide rod 311 is fixedly connected to the outer wall of the wedge block A312, the trapezoidal block 310 is slidably connected to the inner wall of the mounting block 301, and the clamping block 4 contacts the movable end of the cylinder 2.

[0024] The above solution is adopted: when installing the clamping block 4, the clamping block 4 is inserted into the movable end of the cylinder 2, and the mounting block 301 is inserted into the connecting block 302. The arc surface of the wedge block A312 and the wedge block B307 is squeezed by the inner wall of the connecting block 302, so that the two move toward the inner wall of the mounting block 301 at the same time. The wedge block B307 drives the sliding rod 313 to move synchronously and compress the elastic member A308. When the two sets of wedge blocks A312 move toward the middle, the sliding rod 313 drives the slider 309 and the trapezoidal block 310 to move synchronously. When the clamping block 4 can no longer be in the movable end of the cylinder 2, When moving inward, the wedge block A312 and the wedge block B307 correspond to the positions of the groove A303 and the groove B304 respectively. Under the elastic force of the elastic member A308, the sliding rod 313 drives the wedge block B307 to pop outward and engage with the groove B304. When the sliding rod 313 moves, it drives the slider 309 and the trapezoidal block 310 to move synchronously. The inclined surface of the trapezoidal block 310 squeezes the guide rods 311 on both sides, causing it to drive the corresponding wedge block A312 to move to both sides and engage with the groove A303, thereby completing the installation and fixation of the clamping block 4.

[0025] like Figures 2 to 4 As shown, when the clamping block 4 needs to be removed for replacement, the shift block 305 can be moved. The shift block 305 is slidably connected to the inner wall of the mounting block 301. When it moves, the hinge rod 306 will flip and drive the sliding rod 313 to move, and compress the elastic member A308, so that the wedge block B307 is out of contact with the groove B304. At the same time, the sliding rod 313 drives the slider 309 and the trapezoidal block 310 to move synchronously. The inclined surface of the trapezoidal block 310 generates a force on the guide rod 311, so that the guide rod 311 moves along its inclined surface, and drives the corresponding wedge block A312 to move toward the middle at the same time. The wedge block A312 is out of contact with the groove A303, and the clamping block 4 can be removed conveniently and quickly.

[0026] like Figures 5 to 7 As shown, the outer wall of the waste bin 501 is slidably connected to a handle 502, the outer wall of the handle 502 is hinged to a sliding plate 505 through a rotating rod 503, the sliding plate 505 is elastically connected to the inner wall of the waste bin 501 through a reset spring 504, the inner wall of the bottom end of the sliding plate 505 is elastically connected to a dredging block 512 through an elastic member B511, the outer wall of the sliding plate 505 is fixedly connected to an extrusion block 506, the inner wall of the waste bin 501 is elastically connected to a rotating shaft 509 through a spiral spring 508, and the outer wall of the rotating shaft 509 is fixedly connected to a baffle 507.

[0027] The above solution is adopted: the handle 502 passes through the rear outer wall of the waste bin 501, which can move up and down the outer wall of the waste bin 501, and drives the rotating rod 503 connected to it to move synchronously; the side wall of the sliding plate 505 is slidably connected to the inner wall of the waste bin 501, and it can only move horizontally in the inner wall of the waste bin 501 without tilting; a dust suction head is provided in the dust suction module 6, which can suck the powdered waste on the grinding table 1 and transport it to the waste bin 501 for collection through the connecting pipe provided at the rear end, and then transport it to the external equipment through the pipeline below the waste bin 501 for processing; since the powdered waste on the grinding table 1 is required during the grinding process When spraying coolant, the powdered waste chips may contain moisture, and moisture will cause the waste chips to clump. In order to prevent large agglomerated waste chips containing moisture from adhering to the pipe below the waste box 501 and causing blockage, they cannot pass through the holes of the sieve plate 510 when they fall on the sieve plate 510, but remain on the sieve plate 510. However, after long-term use, waste chips containing moisture may adhere to the holes of the sieve plate 510 and cause blockage. By setting the dredging block 512, the holes can be dredged, and the waste chips remaining on the sieve plate 510 can be discharged from the opening at the baffle 507 by moving the sliding plate 505, so that they will not remain in the waste box 501.

[0028] like Figures 5 to 7 As shown, the waste bin 501 is connected to the dust collection module 6 through a connecting pipe, and the two ends of the rotating rod 503 are hinged to the outer walls of the sliding plate 505 and the handle 502 respectively. The sliding plate 505 is slidably connected to the inner wall of the waste bin 501, and the outer wall of the bottom end of the sliding plate 505 contacts the outer wall of the top end of the sieve plate 510; one end of the return spring 504 is fixedly connected to the inner wall of the waste bin 501, and the other end of the return spring 504 is fixedly connected to the outer wall of the sliding plate 505. One end of 508 is fixedly connected to the outer wall of the rotating shaft 509, the other end of the spiral spring 508 is fixedly connected to the inner wall of the waste box 501, and the rotating shaft 509 is rotatably connected in the inner wall of the waste box 501; one end of the elastic part B511 is fixedly connected to the outer wall of the dredge block 512, the other end of the elastic part B511 is fixedly connected to the inner wall of the bottom end of the sliding plate 505, the dredge block 512 is slidably connected in the inner wall of the sliding plate 505, and the dredge block 512 is in contact with the screen plate 510.

[0029] When the handle 502 is pressed downward, the rotating rod 503 will flip over and push the sliding plate 505 to move, stretching the return spring 504. Since the sliding plate 505 is in contact with the screen plate 510, the waste debris on the surface of the screen plate 510 will be scraped off during movement, and when the sliding plate 505 moves to the extrusion block 506 and contacts the baffle 507, when it continues to move, the extrusion block 506 will squeeze the baffle 507 to make it flip upward, driving the rotating shaft 509 to rotate synchronously, causing the volute spring 508 to be forced to contract, and the waste debris on the screen plate 510 will be pushed out of the waste bin 501 from the baffle 507; during the movement of the sliding plate 505, when the dredging block 512 moves to the position corresponding to the hole on the screen plate 510, it will pop out and insert into the hole under the elastic force of the elastic member B511, squeezing the agglomerated waste debris blocked in the hole downward and out The waste is discharged from the pipe below the waste box 501; the bottom of the dredging block 512 is an arc surface, and during the movement of the sliding plate 505, it will be squeezed by the inner wall of the hole of the screen plate 510, causing the dredging block 512 to move into the inner wall of the sliding plate 505, so that during the movement, it will continue to retract and pop out to dredge all the holes on the screen plate 510. When the surface of the screen plate 510 is cleaned, the handle 502 can be released, and the sliding plate 505 moves and resets under the elastic force of the reset spring 504, and the squeezing block 506 is disengaged from the baffle 507. The elastic force of the spiral spring 508 causes the rotating shaft 509 and the baffle 507 to flip in the opposite direction, closing the waste box 501, and returning to the initial state. Through the setting of the collecting mechanism 5, there is no need to manually clean the waste on the grinding table 1, and it is more convenient to handle the waste remaining on the screen plate 510, and it is easy to use.

[0030] The present application also proposes a method for using an ultra-high pressure special-shaped piston processing device, comprising the following steps: S1. Place the piston to be processed on the polishing table 1. Select the appropriate clamping block 4 according to the piston shape. First, move the shifting block 305 to drive the wedge block A312 and the wedge block B307 to disengage from the groove A303 and the groove B304 respectively. Remove the previous clamping block 4, and then insert the appropriate clamping block 4 into the movable end of the cylinder 2. The wedge block A312 and the wedge block B307 engage with the groove A303 and the groove B304 in the connecting block 302 respectively to complete the fixing of the clamping block 4. Start the cylinder 2 and drive the two sets of clamping blocks 4 to move synchronously toward the center until the piston is clamped. S2: The motor of the grinding module 7 drives the grinding head to rotate at high speed to perform precision machining on the top surface of the piston. The dust collection module 6 is started simultaneously. The dust collection head sucks in the generated dust and waste chips. The dust-laden airflow is transported to the waste chip box 501 through the connecting pipe. The agglomerated waste chips containing coolant are intercepted by the sieve plate 510. The fine dust-like waste chips fall through the holes and are discharged through the pipe below the waste chip box 501 for treatment. S3. After polishing is completed, the handle 502 is pressed downward, and the sliding plate 505 is driven to slide along the surface of the sieve plate through the rotating rod 503. The dredging block 512 is periodically inserted into the holes of the sieve plate 510 under the action of the elastic member B511 to squeeze out the agglomerated waste in the holes to avoid blockage. The squeezing block 506 pushes open the baffle 507 to discharge the waste remaining on the sieve plate 510 out of the box; S4. After releasing the handle 502, the return spring 504 drives the sliding plate 505 to return to its original position, and the spiral spring 508 drives the rotating shaft 509 and the baffle 507 to return to their original position, closing the discharge port, and then the grinding operation can be continued.
