Description

Technical Field

[0001] The present invention relates to the technical field of polishing equipment, in particular to a polishing equipment for producing a booster pump regulating valve. Background Art

[0002] The boost pump regulating valve is also called a hydraulic reversing valve. The working principle of the hydraulic reversing valve is that when the valve core moves a certain distance to the right, the pressure oil output by the hydraulic pump flows to the left chamber of the hydraulic cylinder, and the oil in the right chamber of the hydraulic cylinder flows back to the oil tank, and the hydraulic cylinder piston moves to the right. If the valve core moves a certain distance to the left, the liquid flow is reversed and the piston moves to the left. In the production and manufacturing of regulating valves, polishing work is required. Among them, vibration polishing machines are widely used due to their high batch efficiency. The current polishing equipment for the production of boost pump regulating valves is not convenient for preventing the accumulation of regulating valves, which affects the uniformity of polishing. At the same time, the traditional direct stirring method is also prone to valve body collision. It is also not convenient for polishing the valve hole. The polishing efficiency inside and outside the valve body is different, which affects the polishing consistency. It is not convenient to stop polishing after real-time testing of the polishing completion. The internal roughness of different valve holes is different, which easily causes excessive polishing wear of some valve bodies.

[0003] Therefore, the present application provides a polishing device for the production of booster pump regulating valves to meet the needs. Summary of the Invention

It is also noted that, for the sake of completeness, the following embodiments are best and preferred embodiments, and those skilled in the art may employ alternative implementations for known techniques. Furthermore, the accompanying drawings are intended only to provide a more detailed description of the embodiments and are not intended to limit the present invention.

Furthermore, when specific features, structures, or characteristics are described in conjunction with an embodiment, it is within the knowledge of persons skilled in the relevant art to implement such features, structures, or characteristics in conjunction with other embodiments (whether or not explicitly described).

[0036] like Figures 1 to 10 As shown, an embodiment of the present invention provides a polishing device for the production of a booster pump regulating valve, including a polishing connector, a spacer installed on the polishing connector, the spacer is used to prevent the regulating valve from accumulating; an inner hole polishing part is installed on the polishing connector; the inner hole polishing part is used to add vibration polishing particles; a circle of vibration discharge parts 4 is installed on the inner hole polishing part; a circle of vibration discharge parts 4 is used to polish the inner hole of the regulating valve; a polishing test part 5 is installed on the vibration discharge part 4; the polishing test part 5 is used to test the polishing smoothness; a circle of magnetic prompt parts 6 is installed on the inner hole polishing part; the magnetic prompt part 6 is used to magnetically attract the regulating valve; a circle of closing parts 7 is installed inside the inner hole polishing part; a circle of closing parts 7 is used to prevent the inner wall of the regulating valve from being over-polished; the polishing connector includes: a support seat 101 and a vibration connecting groove 102, the inner side of the support seat 101 is provided with a vibration connecting groove 102, and a gap is provided between the outer side of the vibration connecting groove 102 and the inner side of the support seat 101.

[0037] like Figures 2 to 5As shown, the polishing connecting member also includes a circle of support springs 103 fixedly mounted on the support seat 101; and the other ends of the circle of support springs 103 are respectively connected to the vibration connecting groove 102; a vibration motor 104 is sleeved inside the vibration connecting groove 102; a circle of conductive sheets 1021 are fixedly mounted on the vibration connecting groove 102, and a circle of conductive sheets 1021 are provided with intervals; the spacing member includes a driving motor 201 fixedly mounted on the inner side of the vibration connecting groove 102; the output shaft of the driving motor 201 passes through the vibration connecting groove 102; a rotating arm 202 is fixedly mounted on the output shaft of the driving motor 201; a bottom electromagnet 203 is installed at the bottom of the rotating arm 202; a top electromagnet 204 is fixedly mounted on the rotating arm 202; a interval is provided between the bottom electromagnet 203 and the top electromagnet 204; an electric spring 20 is fixedly mounted on the inner side of the rotating arm 202 21; The electrical spring piece 2021 is used to elastically fit the conductive sheet 1021. The use of a spacing piece can utilize magnetic attraction to prevent the regulating valves from piling up when the regulating valves are vibrating and polishing in batches, thereby affecting the vibration and polishing effect. At the same time, this structure adopts a magnetic control interval distribution regulating valve method to prevent the regulating valves from excessive collision and affecting the polishing quality. The structure is more reasonable, which can ensure the safety of this structure, reduce the defective rate, and avoid the problem of traditional stirring and dispersing regulating valves that easily increase scratches on the surface of the regulating valve. Because a circle of conductive sheets 1021 is provided with a gap, the bottom electromagnet 203 and the top electromagnet 204 can intermittently pass the electromagnetic attraction regulating valve. As the bottom electromagnet 203 and the top electromagnet 204 move, if the regulating valves are piled up, some of the regulating valves will be magnetically attracted and displaced by the bottom electromagnet 203 and the top electromagnet 204 to assist in dispersing the regulating valves.

[0038] like Figures 2 to 8As shown, the inner hole polishing part includes a particle circulation circle 301 fixedly mounted on the top electromagnet 204; the particle circulation circle 301 is a hollow structure; a prompt light strip 3011 is fixedly mounted on the particle circulation circle 301; a row of light beads are provided inside the prompt light strip 3011; a particle conveying fan 302 is installed at the bottom of the particle circulation circle 301; the particle conveying fan 302 is used to suck the vibration polishing particles; a rotary motor 303 is installed on the side of the particle circulation circle 301; a gear is provided on the output shaft of the rotary motor 303; a drive toothed belt 304 is provided above the particle circulation circle 301, and the drive toothed belt 304 is engaged with the gear on the output shaft of the rotary motor 303; the vibrating discharge part 4 includes a circle of guide rotary drum 401 rotatably mounted inside the particle circulation circle 301; a circle of through holes is provided below the guide rotary drum 401; the top of the guide rotary drum 401 passes through the particle circulation circle 301; a rotating gear 402 is fixedly installed on the top of the diversion rotary cylinder 401, and the rotating gear 402 is engaged with the driving toothed belt 304; a vibration discharge cylinder 403 is fixedly installed on the bottom of the diversion rotary cylinder 401; a discharge hole is provided on the outside of the vibration discharge cylinder 403; the vibration discharge cylinder 403 is used to discharge vibration polishing particles to polish the inner hole of the regulating valve; the use of a vibration discharge piece 4 can facilitate the polishing process of the inside of the valve hole inside the regulating valve by this structure, and at the same time, the vibration discharge piece 4 can improve the comprehensiveness of the polishing of the regulating valve by this structure, and avoid the problem of different internal and external polishing effects of traditional regulating valves using vibration polishing. The inner hole polishing piece can realize the conveying of polishing particles and perform comprehensive vibration polishing. The polishing particles can then polish the inner wall of the regulating valve, and the rotatable vibration discharge cylinder 403 can further improve the polishing effect of the inner hole of the regulating valve and improve uniformity.

[0039] like Figures 2 to 10As shown, the polishing test piece 5 includes an inner hole spring piece 501 fixedly mounted on the outside of the vibration discharge cylinder 403; a fitting cotton pad 502 is fixedly mounted on the outside of the inner hole spring piece 501; the fitting cotton pad 502 is used to elastically fit the edge of the inner hole of the regulating valve; the magnetic prompting member 6 includes a magnetic rotating ring 601 rotatably mounted on the bottom of the particle circulation circle 301; a swinging electric connecting piece 6011 is fixedly mounted on the magnetic rotating ring 601; tension springs 602 are fixedly mounted on both sides of the swinging electric connecting piece 6011; The two ends of the two tension springs 602 are respectively connected to the outside of the particle circulation circle 301; the particle circulation circle 301 is fixedly installed with a dislocation spring piece 603; the dislocation spring piece 603 elastically fits the outside of the swinging power connection piece 6011; the dislocation spring piece 603, the swinging power connection piece 6011 and the lamp beads inside the prompt light strip 3011 are connected in series with the power supply; the magnetic prompt member 6 also includes a positioning electromagnet 604 fixedly installed at the bottom of the magnetic rotating ring 601; the positioning electromagnet 604 is used for magnetic positioning regulating valve; the diversion rotation The cylinder 401 passes through the magnetic rotating ring 601 and the positioning electromagnet 604; the polishing test piece 5 can be used to indicate the smoothness of the inner hole of the regulating valve, and it also helps to rub the edge of the inner hole of the regulating valve to promote polishing. It can be used in conjunction with the magnetic prompt piece 6 to give clear instructions. The roughness of the rough burrs on the edge of the inner hole of the regulating valve can be used for detection. Excessive polishing and wear of the inner hole of the regulating valve will affect the fitting accuracy of the regulating valve, reduce its service life, and increase safety hazards. This structure can be tested in real time. If there are burrs or too much roughness inside the valve hole, it can scratch the fitting cotton pad 502 and cause jamming. At this time, the vibration discharge cylinder 403 cannot rotate normally. Under the torsional force of the vibration discharge cylinder 403, the magnetic rotating ring 601 will rotate, driving the swinging electrical connection piece 6011 to swing and separate from the dislocated spring piece 603. The prompt light strip 3011 can be turned off. After polishing for a long time, the prompt light strip 3011 remains in a normally off state. At this time, the regulating valve can be disassembled for inspection to see if it meets the polishing requirements.

[0040] like Figures 2 to 9 As shown, the closing member 7 includes an upper electromagnet 701 fixedly mounted on the top side of the particle circulation circle 301; the bottom of the upper electromagnet 701 is magnetically connected to a closing sleeve 702; the closing sleeve 702 is sleeved on the guide rotary drum 401; the closing sleeve 702 is used to close a circle of through holes on the guide rotary drum 401; the closing member 7 also includes a lower electromagnet 703 fixedly mounted on the bottom of the inner side of the particle circulation circle 301, and the lower electromagnet 703 is sleeved on the guide rotary drum 401; the lower electromagnet 703 is aligned with the closing sleeve 702; the use of the closing member 7 can close the guide rotary drum 401 in time after the polishing of the inner hole of the regulating valve is completed, which can further prevent the guide rotary drum 401 from continuously discharging polishing particles, causing excessive polishing, and can ensure the operational flexibility of this structure. The regulating valve that has completed polishing can be disassembled and inspected to ensure the safety of this structure, and it can also avoid the guide rotary drum 401 from continuously discharging polishing particles without resistance, thereby reducing the particle utilization rate.

[0041] The working principle of the technical solution provided by the present invention is as follows:

[0042] First, start the vibration motor 104, put the vibration abrasive on the vibration connecting groove 102, and place the regulating valve in batches in the abrasive. At this time, the driving motor 201 drives the rotary arm 202 to rotate, driving the electrically connected spring piece 2021 to fit a circle of conductive sheets 1021. Because a circle of conductive sheets 1021 is spaced apart, the bottom electromagnet 203 and the top electromagnet 204 can intermittently pass through the electromagnetic suction regulating valve. As the bottom electromagnet 203 and the top electromagnet 204 move, if the regulating valves are stacked together, some of the regulating valves will be magnetically attracted and driven to move by the bottom electromagnet 203 and the top electromagnet 204 to assist in dispersion. When it is necessary to polish the inner hole of the regulating valve, the inner hole of the regulating valve is concentrically inserted into the vibration discharge cylinder 403, and the regulating valve magnetic positioning electromagnet 604 is positioned. The polishing particles are input into the particle circulation circle 301 through the particle conveying fan 302 and then discharged from the vibration discharge cylinder 403. As the polishing particles are discharged and vibrated, the polishing particles can polish the inner wall of the regulating valve. The light works, and the rotatable vibration discharge cylinder 403 can further improve the polishing effect of the inner hole of the regulating valve and improve the uniformity. At this time, as the vibration discharge cylinder 403 rotates, it drives the fitting cotton pad 502 to fit the inner hole of the regulating valve together, and cooperates with the elastic fit of the inner hole spring piece 501. At this time, if there are burrs or excessive roughness inside the valve hole, the fitting cotton pad 502 can be scraped and stuck. At this time, the vibration discharge cylinder 403 cannot rotate normally. Under the torsional force of the vibration discharge cylinder 403, the magnetic rotating ring 601 will rotate, driving the swinging power strip 6011 to swing and separate from the dislocated spring piece 603, and the warning light strip 3011 will be turned off. After polishing for a long time, the warning light strip 3011 remains in the off state. At this time, the regulating valve can be disassembled for inspection. At the regulating valve that needs to be disassembled, control the lower electromagnet 703 to be energized and the upper electromagnet 701 to be de-energized. The lower electromagnet 703 can magnetically attract the sealing sleeve 702 to move down to close the diversion rotary cylinder 401 to prevent continuous emission of particles.
