Description

Technical Field

[0001] This utility model belongs to the field of all-metal valve processing technology, specifically relating to an all-metal valve inner circle grinding device. Background Technology

[0002] Metal valve castings are control components in pipeline fluid transport systems. They are used to change the cross-section of the passage and the direction of medium flow, and have functions such as guiding, shutting off, regulating, saving, checking back, diverting or overflowing pressure relief. During the processing of metal valve castings, the inner circle needs to be ground by a grinding device.

[0003] Chinese patent number (CN212286952U) discloses a grinding device for the inner circle of steel pipes of various specifications. The grinding device is equipped with a grinding mechanism. The driving motor of the grinding mechanism drives the rotating rod to rotate, which in turn drives the rotating plate to rotate. The rotating plate rotates through a grinding roller connected by a connecting rod, thereby grinding the inner circle of the steel bar. The rotating plate has regularly opened connecting holes, which can adjust the radius of rotation of the grinding roller to adapt to the grinding of the inner circle of steel pipes of different specifications.

[0004] However, during the grinding process of metal valves, the inner diameter of the metal valve will continue to increase as the amount of grinding increases. Since the number and position of the connecting holes of the inner circle grinding device are fixed, the grinding block with a constant position will separate from the inner circle as the inner diameter continues to be ground, resulting in the inability to continuously grind the inner circle and poor grinding effect. Utility Model Content

[0005] (1) Technical problems to be solved

[0006] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an all-metal valve inner circle grinding device. This all-metal valve inner circle grinding device aims to solve the technical problem that in the prior art, because the number and position of the connecting holes of the inner circle grinding device are fixed, the grinding block with a constant position will separate from the inner circle as the inner diameter is continuously ground, resulting in the inability to continuously grind the inner circle and the poor grinding effect of the inner circle.

[0007] (2) Technical solution

[0008] To solve the above-mentioned technical problems, this utility model provides an all-metal valve inner circle grinding device, which includes a base and a rotating seat rotatably disposed in the base. A metal valve body is axially positioned at the top of the rotating seat. Fixed seats are embedded in both sides of the top surface of the base. A clamping mechanism for positioning the metal valve body is provided at the close end of the two fixed seats. A lifting plate is slidably inserted into the top of the fixed seat. A lead screw is rotatably installed between the two lifting plates. A moving block is threaded onto the lead screw. A grinding block embedded in the metal valve body is fixed at the bottom end of the moving block.

[0009] When using this technical solution, fixed seats are embedded on both sides of the top surface of the base. A lead screw is installed on the lifting plate at the top of the fixed seat. When the inner wall of the metal valve body is worn during grinding, the rotating part drives the lead screw to rotate, causing the moving block to drive the grinding block to connect tightly with the inner wall of the metal valve body. During the rotation of the metal valve body, it contacts the grinding block for grinding. After the position of the grinding block is adjusted, the knob bolt is tightened to abut against the lead screw, keeping the lead screw axially positioned. This facilitates the adjustment of the position of the grinding block, ensuring that the grinding block is continuously in close contact with the inner wall of the metal valve body, thus improving the grinding effect on the metal valve body. By installing a rotating seat at the top of the base, the metal valve body is embedded in the rotating seat. The positioning rod at the top of the rotating seat is inserted into the metal valve body to keep it axially positioned. At the same time, the first electric push rod drives the ball bearings on the inner wall of the clamping plate to connect tightly with the outer wall of the metal valve body, improving the stability of the metal valve body during grinding.

[0010] Preferably, a motor connected to a rotating seat is fixedly installed at the bottom of the base, and positioning rods inserted into both sides of the inner wall of the rotating seat are fixed thereon.

[0011] Furthermore, the clamping mechanism includes a first electric push rod mounted on the side wall of the fixed seat and a clamping plate fixedly mounted on the first electric push rod.

[0012] Furthermore, the inner wall of the clamping plate is embedded with ball bearings, which are tightly connected to the outer wall of the metal valve body.

[0013] Furthermore, a second electric push rod is embedded in the fixed base, and the lifting plate extends into the bottom end of the fixed base and is fixedly connected to the second electric push rod.

[0014] Furthermore, a sliding rod is fixedly installed between the two lifting plates, and the sliding rod is slidably inserted into the moving block.

[0015] Furthermore, both ends of the lead screw are fixedly installed with rotating parts through the lifting plate, and the top of the lifting plate is threaded with a knob bolt that abuts against the lead screw.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This utility model features fixed seats embedded on both sides of the top surface of the base, with a lead screw mounted on the lifting plate at the top of the fixed seats. When the inner wall of the metal valve body experiences grinding wear, the rotating part drives the lead screw to rotate, causing the moving block to tightly connect the grinding block with the inner wall of the metal valve body. This allows the metal valve body to contact and grind with the grinding block during rotation. After adjusting the position of the grinding block, tightening the knob bolt to abut against the lead screw keeps the lead screw axially positioned, facilitating the adjustment of the grinding block's position and ensuring continuous tight connection between the grinding block and the inner wall of the metal valve body, thus improving the grinding effect on the metal valve body.

[0019] By installing a rotating seat at the top of the base, the metal valve body is embedded in the rotating seat. The positioning rod at the top of the rotating seat is inserted into the metal valve body to keep it axially positioned. At the same time, the first electric push rod drives the ball bearings on the inner wall of the clamping plate to connect tightly with the outer wall of the metal valve body, which improves the stability of the metal valve body during grinding.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This specific embodiment is an all-metal valve inner circle grinding device, the structural schematic diagram of which is shown below. Figure 1 and Figure 2 As shown, the all-metal valve inner circle grinding device includes a base 1 and a rotating seat 2 rotatably disposed in the base 1. A metal valve body 3 is axially positioned at the top of the rotating seat 2. Fixed seats 4 are embedded in both sides of the top surface of the base 1. A clamping mechanism for positioning the metal valve body 3 is provided at the close end of the two fixed seats 4. A lifting plate 8 is slidably inserted into the top of the fixed seat 4. A lead screw 7 is rotatably installed between the two lifting plates 8. A moving block 6 is threaded onto the lead screw 7. A grinding block 11 embedded in the metal valve body 3 is fixed at the bottom end of the moving block 6.

[0028] A motor 10 connected to a rotating seat 2 is fixedly installed at the bottom of the base 1. Positioning rods 14, which are inserted into both sides of the inner wall of the rotating seat 2, are fixed on both sides of the metal valve body 3. The clamping mechanism includes a first electric push rod 9 installed on the side wall of the fixed seat 4 and a clamping plate 5 fixedly installed on the first electric push rod 9. A ball bearing 15 is embedded in the inner wall of the clamping plate 5. The ball bearing 15 is tightly connected to the outer wall of the metal valve body 3. The metal valve body 3 is embedded in the rotating seat 2. The positioning rod 14 at the top of the rotating seat 2 is inserted into the metal valve body 3 to keep it axially positioned. At the same time, the first electric push rod 9 drives the ball bearing 15 on the inner wall of the clamping plate 5 to be tightly connected to the outer wall of the metal valve body 3.

[0029] like Figure 3 and Figure 4 As shown, a second electric push rod 13 is embedded in the fixed base 4. The lifting plate 8 extends into the bottom end of the fixed base 4 and is fixedly connected to the second electric push rod 13. A slide rod 12 is fixedly installed between the two lifting plates 8. The slide rod 12 is slidably inserted into the moving block 6. Both ends of the lead screw 7 pass through the lifting plate 8 and are fixedly installed with rotating parts 17. The top of the lifting plate 8 is threaded with a knob bolt 16 that abuts against the lead screw 7. When the inner wall of the metal valve body 3 is worn by grinding, the rotating part 17 drives the lead screw 7 to rotate, so that the moving block 6 drives the grinding block 11 to be tightly connected to the inner wall of the metal valve body 3, and the metal valve body 3 contacts the grinding block 11 for grinding during the rotation. After the position of the grinding block 11 is adjusted, the knob bolt 16 is tightened to abut against the lead screw 7, so that the lead screw 7 is axially positioned.

[0030] Working principle: When using the device of this technical solution, the metal valve body 3 is embedded in the rotating seat 2. The positioning rod 14 at the top of the rotating seat 2 is inserted into the metal valve body 3 to keep it axially positioned. At the same time, the first electric push rod 9 drives the ball bearings 15 on the inner wall of the clamping plate 5 to be tightly connected to the outer wall of the metal valve body 3. The two second electric push rods 13 are started to move synchronously, causing the lifting plate 8 to drive the lead screw 7 and the grinding block 11 to move into the metal valve body 3. The motor 10 is started to drive the rotating seat 2 and the metal valve body 3 to rotate, and during the rotation, they interact with the grinding block 11. 1. Contact grinding: When the inner wall of the metal valve body 3 is worn out by grinding, the rotating part 17 drives the lead screw 7 to rotate, causing the moving block 6 to drive the grinding block 11 to be tightly connected with the inner wall of the metal valve body 3. During the rotation, the metal valve body 3 contacts the grinding block 11 for grinding. After the position of the grinding block 11 is adjusted, the knob bolt 16 is tightened to abut against the lead screw 7, so that the lead screw 7 is axially positioned, which facilitates the adjustment of the position of the grinding block 11. This ensures that the grinding block 11 is continuously tightly connected with the inner wall of the metal valve body 3, improving the grinding effect of the metal valve body 3.
