Description

Technical Field

[0001] This invention relates to the field of grinding equipment technology, specifically to an internal wall grinding device based on valve processing. Background Technology

[0002] Valve internal wall grinding devices are a type of precision machining equipment specifically designed for valve internal walls and key functional surfaces. The core of the equipment is to remove excess material, burrs, or defects from the valve body internal wall through the rotary cutting and precise feed motion of the grinding tool, ultimately achieving the dimensional accuracy, surface roughness, and sealing performance required by the design. It is a key piece of equipment in valve manufacturing to ensure the smoothness, sealing, and service life of the fluid passage.

[0003] For example, CN215239906U discloses an internal wall grinding device for valve processing, which includes a base, support legs at the four corners of the bottom of the base, a working box at the top of the base, water tanks at both ends of the working box, a water pump at the top of the water tank, and a water delivery pipe at the top of the water pump. The water tank is manually filled with water. During the valve grinding process, a water pump draws water from the tank into a water pipe, which then delivers the water to a spray nozzle. The nozzle sprays water onto the valve to reduce dust and cool it down, preventing sparks and reducing dust adhesion. It also cleans the valve of dirt and allows for faster use after cooling. Finally, wastewater flows into a wastewater recycling tank through a collection port at the bottom of the work chamber for recycling. This not only reduces fire hazards but also improves work efficiency. However, during the processing, the valve body is only clamped and fixed by a clamping device. When the tool moves downward during grinding, the grinding force between it and the valve body causes the valve body to slide downward, potentially causing it to fall off. Additionally, if the rotation center position deviates from the rotation center position of the valve body's inner wall during grinding, it can easily lead to grinding misalignment. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention is implemented through the following technical solution: an internal wall grinding device based on valve processing, comprising:

[0005] A base, on the top of which is mounted a side plate, and a hydraulic cylinder is fixedly mounted on the outer side of the side plate, and a grinding mechanism is fixedly mounted on the output end of the hydraulic cylinder;

[0006] An adjustment mechanism and a clamping mechanism are provided, wherein the adjustment mechanism is installed at the center of the top of the base, and the clamping mechanism is installed on top of the adjustment mechanism;

[0007] The clamping mechanism includes side support plates, which are evenly installed on top of the adjusting mechanism. Cylinders are fixedly installed on the non-opposing sides of the side support plates. The output ends of the cylinders pass through the side support plates and extend to the other side. An inclined groove plate is fixedly installed at the output end of each cylinder. Inclined sliding grooves are formed on both sides of the inclined groove plate, and these grooves slope downwards from top to bottom away from the side support plates. Side sliding strips are slidably installed at the inclined sliding grooves of the inclined groove plate. A rubber gasket is engaged at the bottom of the inclined groove, with the top of the rubber gasket fitting against the bottom of the side sliding strip. A slotted plate is fixedly installed on the outer side of the side sliding strip. The clamping mechanism is further oriented by the inclined groove. The inclined groove of the slot plate cooperates with the side slide bar. During the grinding process of the grinding tool grinding the inner wall of the valve body from top to bottom, a downward force is generated, causing the valve body to tend to move downward. At this time, the friction between the valve body and the rubber pad plate transmits the movement tendency to the side slide plate, causing the side slide plate to slide downward synchronously with the valve body. The inclination of the inclined groove makes the rubber pad plate and the side top bar tend to clamp the valve body inward, restricting the movement of the valve body and preventing the grinding tool from falling off during the grinding process of the inner wall of the valve body from top to bottom. The center position of the slot plate away from the inclined groove plate is provided with a plate groove, and a rubber pad plate is fixedly installed at the plate groove of the slot plate.

[0008] Preferably, side top strips are fixedly installed at both ends of the slot plate on the side away from the inclined slot plate. The side top strip on the side away from the slot plate is a raised arc surface. The arc surface of the side top strip contacts the surface of the valve body. During the clamping process, the valve body is clamped by the side top strips. When fixed, the position of the valve body is positioned so that the valve body is perpendicular to the horizontal plane after contacting the arc surface of the side top strip. At the same time, during the processing, the force generated by grinding the inner wall of the valve body is transmitted to the side top strips, which restricts the valve body from tilting and prevents errors in the grinding depth of the valve body. A conical disk is fixedly installed between the side support plates. The top of the conical disk is a conical surface with a raised center position, and the conical disk is located below the inclined slot plate.

[0009] Preferably, the adjusting mechanism includes a fixed base, the bottom of which is fixedly connected to the top of a base, and a lead screw is rotatably mounted on the inner wall of the fixed base. The lead screw is symmetrically mounted along the center of the axis of the fixed base. A first motor is fixedly mounted on the outer side of the fixed base, and the first motor is symmetrically mounted along the center of the axis of the fixed base. The output end of the first motor is fixedly connected to one end of the lead screw. Two horizontal plates are threaded onto the outer side of the lead screw, and a support plate is fixedly mounted between the horizontal plates. A rectangular groove is formed at the center of the bottom of the horizontal plate. A bottom support plate is fixedly mounted at the center of the inner wall of the fixed base. The two sides of the bottom support plate are in contact with the two sides of the rectangular groove of the horizontal plate, and a sliding rod is fixedly mounted on the top of the bottom support plate. The top of the sliding rod is in contact with the inner wall of the horizontal plate.

[0010] Preferably, a slotted cylinder is fixedly installed at the center of the top of the support plate. Slots are evenly distributed on the outer side of the slotted cylinder. A support plate is fixedly installed at the top of the slotted cylinder. A second motor is fixedly installed at the center of the bottom of the support plate. The output end of the second motor passes through the support plate and extends to its top. A turntable is fixedly installed at the output end of the second motor. A retaining ring is fixedly installed at the bottom of the turntable. Through the contact between the retaining ring and the convex ring, the retaining ring rotates tightly against the outer side of the convex ring during the rotation of the turntable. The convex ring restricts the position of the retaining ring, ensuring that the center of the retaining ring and the center of the rotation axis of the turntable are at the center of the turntable. This ensures that the center of the valve body corresponds to the center of rotation of the turntable, preventing a misalignment between the center of the rotation axis and the center of the valve body, which would result in different grinding depths on the rotating surface of the valve body's inner wall and affect the grinding effect. A convex ring is fixedly installed at the top of the support plate, and the inner wall of the retaining ring fits against the outer side of the convex ring.

[0011] Preferably, the grinding mechanism includes a fixed plate, the bottom of which is fixedly connected to the output end of the hydraulic cylinder, and a top plate is fixedly installed on the outer side of the fixed plate. A third motor is fixedly installed on the top of the top plate, the output end of the third motor passes through the top plate and extends to its bottom, a coupling is fixedly installed on the output end of the third motor, and a drive shaft is fixedly installed on the output end of the third motor through the coupling. A fixed shaft is connected to the bottom flange of the drive shaft, and a shaft clamping disc is fixedly installed on the top of the outer side of the fixed shaft. Through holes are evenly opened on the top of the shaft clamping disc.

[0012] Preferably, an inner pad is fixedly installed on the outer side of the fixed shaft. The inner pad is located below the retaining disc, and a grinding wheel is slidably installed on the outer side of the inner pad. The bottom of the outer side of the grinding wheel is a tapered surface with an outer diameter that gradually decreases from top to bottom. When grinding the rotating surface of the valve body's inner wall, the top of the outer side of the grinding wheel contacts the inner wall of the valve body. When grinding the valve body's inner wall from top to bottom, the tapered surface contacts the un-ground protrusions on the valve body's inner wall during downward movement, preventing the grinding wheel from jamming with the valve body's inner wall during grinding. The outer side of the inner pad is uniformly provided with arc-shaped protrusions, and the inner pad contacts the inner wall of the grinding wheel through these arc-shaped protrusions. A shaft groove disc is fixedly installed on the top of the grinding wheel, and column holes are uniformly opened on the top of the shaft groove disc, with the column holes connecting to the retaining disc. The through holes of the shaft disc correspond one-to-one. Each shaft groove disc has a locking pin fixedly installed at its column hole. The top of the locking pin engages with the through hole of the shaft groove disc. The shaft groove disc and the shaft groove disc are fixed together by the locking pins. When the fixed shaft rotates, the locking pins drive the shaft groove disc, which in turn drives the grinding wheel to rotate. Simultaneously, during rotation, the contact between the bottom pad ring and the bottom pad disc, along with the support of the inner pad cylinder on the inner wall of the grinding wheel, restricts the grinding wheel from shifting or tilting, preventing it from deviating. If the center position of the grinding wheel axis deviates from the rotation axis of the fixed shaft during rotation, the grinding depth cannot be effectively controlled, affecting grinding accuracy. A threaded hole is provided at the bottom of the fixed shaft, and a bolt is threaded into the threaded hole. A bottom pad disc is fixedly installed at the bottom of the grinding wheel, and a bottom pad ring is engaged between the bottom pad disc and the bolt.

[0013] This invention provides an internal wall grinding device based on valve processing. It has the following beneficial effects:

[0014] (i) The valve-based internal wall grinding device, through the cooperation of the inclined groove of the inclined plate and the side slide bar, generates a downward force during the grinding process of the grinding tool grinding the inner wall of the valve body from top to bottom, causing the valve body to tend to move downward. At this time, the friction between the valve body and the rubber pad transmits the movement tendency to the side slide plate, causing the side slide plate to slide downward synchronously with the valve body. By utilizing the inclination of the inclined groove, the rubber pad and the side top bar tend to clamp the valve body inward, restricting the movement of the valve body and preventing the grinding tool from falling off during the grinding process of the inner wall of the valve body from top to bottom.

[0015] (ii) The valve-based internal wall grinding device uses the arc surface of the side top bar to contact the surface of the valve body. During the clamping process, the valve body is clamped by the side top bars. When fixed, the position of the valve body is positioned so that the valve body is perpendicular to the horizontal plane after contacting the arc surface of the side top bar. At the same time, during the processing, the force generated by grinding the inner wall of the valve body is transmitted to the side top bars, which restricts the valve body from tilting and prevents errors in the grinding depth of the valve body.

[0016] (III) The valve-based internal wall grinding device, through the contact between the retaining ring and the convex ring, drives the retaining ring to rotate tightly against the outer side of the convex ring during the rotation of the turntable. The convex ring restricts the position of the retaining ring, so that the center position of the retaining ring and the rotation axis of the turntable is at the center position of the turntable. This ensures that the center position of the valve body corresponds to the rotation center position of the turntable, preventing the center position of the rotation axis from deviating from the center position of the valve body, which would result in different grinding depths on the rotating surface of the valve body and affect the grinding effect.

[0017] (iv) The inner wall grinding device based on valve processing uses a tapered surface with a gradually decreasing outer diameter from top to bottom on the bottom of the outer side of the grinding wheel. When grinding the rotating surface of the inner wall of the valve body, the top of the outer side of the grinding wheel contacts the inner wall of the valve body. When grinding the inner wall of the valve body from top to bottom, the tapered surface contacts the un-grinded protrusions on the inner wall of the valve body during the downward movement, preventing the grinding wheel from getting stuck with the inner wall of the valve body during grinding.

[0018] (v) The valve-based internal wall grinding device uses a locking pin to fix the shaft groove plate and the shaft clamping plate. When the fixed shaft rotates, the locking pin drives the shaft groove plate, which in turn drives the grinding wheel to rotate. During the rotation, the bottom pad ring and the bottom pad plate are in contact, and the inner pad cylinder supports the inner wall of the grinding wheel, which limits the grinding wheel from tilting and prevents it from shifting. If the center position of the grinding wheel axis deviates from the rotation axis of the fixed shaft during rotation, the grinding depth of the grinding wheel cannot be effectively controlled, which affects the grinding accuracy.

[0033] 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.

[0034] For the first embodiment, please refer to... Figures 1 to 2 and Figures 6 to 9 The present invention provides a technical solution:

[0035] An internal wall grinding apparatus based on valve machining, comprising:

[0036] The base 1 has a side plate 5 installed on its top. A hydraulic cylinder 6 is fixedly installed on the outside of the side plate 5, and a grinding mechanism 4 is fixedly installed on the output end of the hydraulic cylinder 6.

[0037] Adjustment mechanism 2 and clamping mechanism 3 are provided. Adjustment mechanism 2 is installed at the center of the top of base 1, and clamping mechanism 3 is installed on top of adjustment mechanism 2.

[0038] The clamping mechanism 3 includes side support plates 31, which are evenly installed on the top of the adjusting mechanism 2. Cylinders 32 are fixedly installed on the non-opposing sides of the side support plates 31. The output end of each cylinder 32 passes through the side support plate 31 and extends to the other side. An inclined groove plate 34 is fixedly installed on the output end of each cylinder 32. Inclined grooves are formed on both sides of the inclined groove plate 34, and these grooves slope downwards from top to bottom away from the side support plate 31. After the worker places the valve body whose inner wall needs to be ground, they start the cylinders 32, causing the cylinders 32 to move the inclined groove plate 34, thus moving the inclined groove... As the plates 34 approach each other, the rubber pad 35 first contacts the surface of the valve body. As the inclined plate 34 continues to move, the contact pressure between the rubber pad 35 and the valve body gradually increases. Simultaneously, the rubber pad 35 compresses and deforms at the groove of the slot plate 36. During this compression and deformation, the side top strips 38 on both sides of the slot plate 36 gradually approach the surface of the valve body until the side top strips 38 clamp the valve body, thus securing and fixing it. Meanwhile, during the grinding process, the arc of the side top strips 38... The convex ribs are in close contact with the surface of the valve body. The arc-shaped convex ribs of the side top ribs 38 restrict the position of the valve body to prevent it from tilting during grinding. Side slide ribs 37 are slidably installed at the inclined slide grooves of the inclined groove plate 34. A rubber gasket ring 39 is engaged at the bottom of the inclined groove of the inclined groove plate 34. The top of the rubber gasket ring 39 fits against the bottom of the side slide rib 37. A retaining plate 36 is fixedly installed on the outer side of the side slide rib 37. A groove is opened at the center of the retaining plate 36 on the side away from the inclined groove plate 34. At the same time, during the grinding process of the tool on the inner wall of the valve body from top to bottom, the tool... The pressure exerted on the valve body causes it to move downwards. The frictional resistance generated by the rubber pad 35 and the side top strip 38 clamping the valve body is transmitted to the side slide strip 37 through the slot plate 36. This causes the side slide strip 37 to slide downwards in the inclined groove of the inclined slot plate 34. The inclination of the inclined groove causes the slot plate 36 to slide downwards synchronously with the valve body, increasing the clamping pressure of the side top strip 38 and the rubber pad 35 on the valve body and restricting the movement of the valve body. The rubber pad 35 is fixedly installed in the slot of the slot plate 36.

[0039] Side top strips 38 are fixedly installed at both ends of the slot plate 36 on the side away from the inclined slot plate 34. The side of the side top strip 38 away from the slot plate 36 is a raised arc surface. A conical disk 33 is fixedly installed between the side support plates 31. The top of the conical disk 33 is a conical surface raised at the center position, and the conical disk 33 is located below the inclined slot plate 34.

[0040] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 3 to 5 As shown, the adjusting mechanism 2 includes a fixed base 201, the bottom of which is fixedly connected to the top of the base 1. A lead screw 205 is rotatably mounted on the inner wall of the fixed base 201. The lead screw 205 is symmetrically mounted along the center of the axis of the fixed base 201. A first motor 202 is fixedly mounted on the outer side of the fixed base 201. The first motor 202 is symmetrically mounted along the center of the axis of the fixed base 201, and its output end is fixedly connected to one end of the lead screw 205. Two horizontal plates 203 are threadedly connected to the outer side of the lead screw 205. A second motor 210 drives a turntable 209 to rotate, causing the turntable 209 to pass through the clamping mechanism 3. The fixed connection drives the valve body to rotate for grinding. During the rotation, the inner wall of the retaining ring 213 fits against the outer side of the convex ring 212, restricting the rotation axis position of the turntable 209 to prevent deviation or tilting under grinding pressure. A support plate 206 is fixedly installed between the horizontal plates 203. A rectangular groove is opened at the center of the bottom of the horizontal plate 203. A bottom support plate 204 is fixedly installed at the center of the inner wall of the fixed seat 201. The two sides of the bottom support plate 204 fit against the two sides of the rectangular groove of the horizontal plate 203. A slide rod 208 is fixedly installed on the top of the bottom support plate 204, and the top of the slide rod 208 contacts the inner wall of the horizontal plate 203.

[0041] A slotted cylinder 207 is fixedly installed at the center of the top of the support plate 206. Slots are evenly opened on the outer side of the slotted cylinder 207. A support plate 211 is fixedly installed at the top of the slotted cylinder 207. A second motor 210 is fixedly installed at the center of the bottom of the support plate 211. The output end of the second motor 210 passes through the support plate 211 and extends to its top. A turntable 209 is fixedly installed at the output end of the second motor 210. When the valve body is placed in the clamping mechanism 3, the first motor 202 drives the lead screw 205 to rotate. The lead screw 205 is connected to the horizontal plate 203 by a thread, which drives the horizontal plate 203 to move, thereby realizing the position adjustment of the valve body. A retaining ring 213 is fixedly installed at the bottom of the turntable 209. A convex ring 212 is fixedly installed at the top of the support plate 211. The inner wall of the retaining ring 213 fits against the outer side of the convex ring 212.

[0042] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 10 to 13As shown, the grinding mechanism 4 includes a fixed plate 401. The bottom of the fixed plate 401 is fixedly connected to the output end of the hydraulic cylinder 6. A top plate 402 is fixedly installed on the outer side of the fixed plate 401. A third motor 403 is fixedly installed on the top of the top plate 402. The output end of the third motor 403 passes through the top plate 402 and extends to its bottom. A coupling 404 is fixedly installed on the output end of the third motor 403. A drive shaft 405 is fixedly installed on the output end of the third motor 403 through the coupling 404. The bottom flange of the drive shaft 405 is connected to a fixed shaft 407, which is fixedly connected to the fixed plate 401 through the hydraulic cylinder 6. The fixed plate 401 drives the top plate 402 to move, adjusting the position and height of the grinding wheel 406 inside the valve body. At the same time, during the grinding process, the third motor 403 drives the drive shaft 405, and the drive shaft 405 drives the fixed shaft 407 to rotate. A retaining plate 408 is fixedly installed on the top of the outer side of the fixed shaft 407. The top of the retaining plate 408 is evenly provided with through holes.

[0043] An inner pad 411 is fixedly installed on the outer side of the fixed shaft 407. The inner pad 411 is located below the shaft clamping disc 408, and a grinding wheel 406 is slidably installed on the outer side of the inner pad 411. The bottom of the outer side of the grinding wheel 406 is a tapered surface with an outer diameter that gradually decreases from top to bottom. Arc-shaped protrusions are evenly arranged on the outer side of the inner pad 411, and the inner pad 411 contacts the inner wall of the grinding wheel 406 through the arc-shaped protrusions. A shaft groove disc 409 is fixedly installed on the top of the grinding wheel 406. The top of the shaft groove disc 409 has evenly spaced column holes, and the column holes correspond one-to-one with the through holes of the shaft clamping disc 408. A retaining pin 410 is fixedly installed at each column hole of the shaft groove disc 409, and the top of the retaining pin 410 engages with the through hole of the shaft clamping disc 408. A screw hole is provided at the bottom end of the fixed shaft 407 for installing the grinding wheel 406. During the process, the grinding wheel 406 is fitted onto the outer side of the inner pad cylinder 411, and the through hole of the retaining disc 408 is aligned with the column hole of the shaft groove disc 409. Then, the retaining disc 408 and the shaft groove disc 409 are fixed together by the retaining column 410. Finally, the bolt 412 is tightened to make the bottom pad ring 413 and the bottom pad disc 414 fit tightly together. The retaining disc 408 is rotated by the fixed shaft 407, which in turn drives the shaft groove disc 409 to rotate through the retaining column 410, thereby driving the grinding wheel 406 to rotate at high speed. The outer side of the grinding wheel 406 contacts the inner wall of the valve body for grinding. The bolt 412 is threaded into the screw hole of the fixed shaft 407. The bottom pad disc 414 is fixedly installed at the bottom of the grinding wheel 406, and the bottom pad ring 413 is engaged between the bottom pad disc 414 and the bolt 412.

[0044] In use, the valve body whose inner wall needs to be ground is placed in the clamping mechanism 3 and fixed by the clamping mechanism 3. Then, the adjusting mechanism 2 cooperates with the hydraulic cylinder 6 to make the hydraulic cylinder 6 drive the grinding mechanism 4 to move up and down. The adjusting mechanism 2 drives the valve body to move through the clamping mechanism 3, and adjusts the position between the grinding tool and the valve body in the grinding mechanism 4 to perform grinding processing, so that the tool grinds the rotating surface of the inner wall of the valve body.

[0045] In the clamping mechanism 3, after the worker places the valve body whose inner wall needs to be ground, the cylinder 32 is activated, causing the cylinder 32 to drive the inclined groove plate 34 to move, bringing the inclined groove plates 34 closer together. During this approach, the rubber pad 35 first contacts the surface of the valve body. As the inclined groove plate 34 continues to move, the contact pressure between the rubber pad 35 and the valve body gradually increases. The rubber pad 35 is compressed and deformed at the groove of the clamping plate 36. Simultaneously, during the compression and deformation of the rubber pad 35, the side top strips 38 on both sides of the clamping plate 36 gradually approach the surface of the valve body until the side top strips 38 clamp the valve body, completing the clamping and fixing of the valve body. Meanwhile, during the grinding process, the arc of the side top strips 38... The convex strips are in close contact with the surface of the valve body. The arc-shaped convex strips of the side top strip 38 restrict the position of the valve body to prevent the valve body from tilting during the grinding process. At the same time, during the grinding process of the inner wall of the valve body from top to bottom, the tool exerts downward pressure on the valve body, causing the valve body to tend to move from top to bottom. The frictional resistance generated by the rubber pad 35 and the side top strip 38 clamping the valve body is transmitted to the side slide strip 37 through the slot plate 36, causing the side slide strip 37 to tend to slide downward in the inclined groove of the inclined slot plate 34. By utilizing the inclination of the inclined groove, the slot plate 36 tends to slide downward synchronously with the valve body, increasing the clamping pressure of the side top strip 38 and the rubber pad 35 on the valve body and restricting the movement of the valve body.

[0046] In the adjustment mechanism 2, the second motor 210 drives the turntable 209 to rotate, so that the turntable 209, through its fixed connection with the clamping mechanism 3, drives the valve body to rotate for grinding. At the same time, during the rotation, the inner wall of the retaining ring 213 fits against the outer side of the convex ring 212, thus restricting the rotation axis position of the turntable 209 and preventing deviation or tilting under grinding pressure. After the valve body is placed in the clamping mechanism 3, when adjusting, the first motor 202 drives the lead screw 205 to rotate. Through the threaded connection between the lead screw 205 and the horizontal plate 203, the horizontal plate 203 is moved, thereby realizing the position adjustment of the valve body.

[0047] In the grinding mechanism 4, the hydraulic cylinder 6 is fixedly connected to the fixed plate 401. The fixed plate 401 drives the top plate 402 to move, adjusting the position and height of the grinding wheel 406 inside the valve body. During grinding, the third motor 403 drives the transmission shaft 405, which in turn drives the fixed shaft 407 to rotate. When installing the grinding wheel 406, the grinding wheel 406 is fitted onto the outside of the inner pad 411, and the through hole of the retaining disc 408 is aligned with the shaft groove. The pin holes of the disc 409 are aligned one by one. Then, the clamping disc 408 and the shaft groove disc 409 are fixed together by the clamping pin 410. Finally, the bolt 412 is tightened to make the bottom washer ring 413 and the bottom washer disc 414 fit tightly together. The fixed shaft 407 drives the clamping disc 408 to rotate, which in turn drives the shaft groove disc 409 to rotate through the clamping pin 410. This drives the grinding wheel 406 to rotate at high speed. The outer side of the grinding wheel 406 contacts the inner wall of the valve body to perform grinding processing.
