Description

Technical Field

[0001] The invention belongs to the technical field of valve grinding and processing, and in particular relates to an inner wall processing device based on valve body processing. Background Art

[0002] Valves are control components in fluid delivery systems and can be used to control the flow of various types of fluids, such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. During the production process of existing valves, a grinding device is required to grind the inner wall of the valve to make the inner wall smoother.

[0003] When grinding the inner wall of the valve, the existing equipment makes the elastic grinding roller contact with the inner wall of the valve body, which easily generates high temperature during the grinding process, causing the valve body to deform, thus affecting the quality of the valve body after grinding. In addition, the valve body and the elastic grinding roller are cooled by pouring coolant. Since the valve body is similar to a three-way pipe structure, the coolant is easy to flow out from the holes vertical to the valve body, which not only increases the amount of coolant used, but also speeds up the replacement frequency of the coolant. To this end, we provide an inner wall processing equipment based on valve body processing to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide an inner wall processing device based on valve body processing, in which the elastic grinding roller moves downward and rotates to grind the inner wall of the valve body, and synchronously controls the external threaded pipe to move downward synchronously with the elastic grinding roller, and synchronously makes the coating roller contact with the rotating inner wall of the valve body, so that the coolant on the coating roller is coated on the inner wall of the valve body, so that the elastic grinding roller lubricates the inner wall of the valve body during the grinding process, and also has a cooling effect on the valve body, so as to avoid the high temperature generated during the grinding process, which causes the valve body to deform and affects the quality of the valve body after grinding. By applying the coolant to the inner wall of the valve body in a smearing manner, excessive waste of coolant is avoided, and the problem that when the existing equipment is grinding the inner wall of the valve, the elastic grinding roller contacts the inner wall of the valve body, high temperature is easily generated during the grinding process, which easily causes the valve body to deform, thereby affecting the quality of the valve body after grinding is solved. In addition, the valve body and the elastic grinding roller are cooled by pouring coolant. Since the valve body is similar to a three-way pipe structure, the coolant can easily flow out from the holes vertical to the valve body, which not only increases the amount of coolant used, but also speeds up the frequency of coolant replacement.

[0042] A special-shaped rod 307 is symmetrically fixedly connected to an inner side surface of the semi-cylindrical tube 301, and an arc plate 308 is fixedly connected to the end of the special-shaped rod 307. A sliding rod 309 that slidably cooperates with the rectangular groove 306 is slidably connected to the side surface of the arc plate 308 close to the movable plate 305. A moving part is slidably connected inside the rectangular groove 306, and the sliding rod 309 is fixedly connected to the moving part. The end of the sliding rod 309 is fixedly connected to the first mounting plate 310, and the bottom of the first mounting plate 310 is rotatably connected to a sliding rod that contacts and cooperates with the inner peripheral side surface of the valve body 201. The outer wall of the semi-cylindrical tube 301 is symmetrically provided with notches 312 adapted to the two smear rollers 311 (the interior of the semi-cylindrical tube 301 is filled with coolant below the notches 312); a grinding assembly 4 is provided on the top of the operating table 101, and the grinding assembly 4 includes an elastic grinding roller 401 that is in contact with the inner circumferential side of the valve body 201 and can move up and down (the elastic grinding roller 401 is a commonly used grinding component in the prior art).

[0043] The operation process of this embodiment is as follows: (in the initial state, the smearing assembly 3 is located below the circular plate 101, and the elastic grinding roller 401 is located above the valve body 2 to avoid interference with the smearing assembly 3 when the valve body 2 is installed) the valve body 2 is fixedly installed in the positioning groove 104 on the circular plate 102, and then the smearing assembly 3 is controlled to move upward along the inner wall of the valve body 201, so that the two smearing rollers 311 on the smearing assembly 3 are pressed against the inner wall near the top of the valve body 201, and the elastic grinding roller 401 is synchronously controlled to move downward, so that the elastic grinding roller 401 moves downward until it contacts the inner wall of the valve body 201, and then the elastic grinding roller 401 is controlled to rotate while the elastic grinding roller 401 also slowly moves downward along the inner wall of the valve body 201. At the same time, the gear ring 105 is controlled to rotate so that the gear ring 105 drives the valve body 2 to rotate through the circular plate 102, so that the rotation direction of the valve body 2 is opposite to that of the elastic grinding roller 401;

[0045] By intermittently controlling the lifting rod 302 to move up and down, when the lifting rod 302 moves downward, the lifting rod 303 drives the semicircular support plate 304 to move downward, thereby driving the sliding rod 309 to move along the arc plate 308 toward the direction close to the semicircular support plate 304, thereby driving the moving plate 305 to move toward the axis of the semicircular support plate 304, and then driving the coating roller 311 to move toward the direction close to the semicircular support plate 304 through the first mounting plate 310, so that the coating roller 311 moves into the coolant inside the semi-cylindrical tube 301, thereby completing the immersion of the coating roller 311 and making the absorbent cloth sleeve full of coolant;

[0046] When the lifting rod 302 moves upward, the lifting rod 303 drives the semicircular support plate 304 to move upward, thereby driving the sliding rod 309 to move along the arc plate 308 in the direction away from the semicircular support plate 304, thereby driving the movable plate 305 to move away from the axis of the semicircular support plate 304, and then driving the coating roller 311 to move away from the semicircular support plate 304 through the first mounting plate 310, so that the coating roller 311 is separated from the coolant and moves to fit the inner wall of the valve body 201. Through the intermittent reciprocating up and down movement of the lifting rod 303, the coating roller 311 is intermittently dipped in the coolant, thereby ensuring that there is sufficient coolant in the liquid-absorbing cloth sleeve on the coating roller 311, thereby ensuring the effect of the coating roller 311 coating the coolant.

[0048] The operation process of this embodiment is: by controlling the two electric push rods 106 to drive the arc clamping plate 107 to move towards the direction close to the valve body 2, the two arc clamping plates 107 are attached to the outer wall of the valve body 201 (the first spring 110 is in a stretched state at this time), and then the valve body 2 is controlled to rotate in the positioning groove 104, so that the hole on the flange 202 in the valve body 2 is rotated to be concentric with the locking rod 108. Under the action of the elastic force of the first spring 110, the locking rod 108 is driven to engage with the hole on the flange 202, thereby completing the position fixation of the valve body 2, thereby ensuring the stability of the inner wall of the valve body 2 during the grinding process.
