Description

Technical Field

[0001] The utility model relates to the field of stainless steel casting, in particular to a grinding device for stainless steel precision casting. Background Art

[0002] Stainless steel is the abbreviation for stainless acid-resistant steel. Steel that is resistant to weak corrosive media such as air, steam, and water, or has rust-proof properties, is called stainless steel, while steel that is resistant to chemical corrosive media (such as acids, alkalis, and salts) is called acid-resistant steel. Stainless steel pipe is a hollow, long, round steel material widely used in industrial pipelines and mechanical structural components in the petroleum, chemical, medical, food, light industry, and mechanical instrumentation industries. In addition, with the same bending and torsional strength, it is lighter in weight, so it is also widely used in the manufacture of mechanical parts and engineering structures. Stainless steel pipes require polishing of the inner and outer walls before use.

[0003] The current grinding device for stainless steel precision casting, as described in the patent announcement number CN217558318U, includes a limiting rod; a screw hole is opened at the front of the limiting rod, and there are four groups of screw holes in total. The four groups of screw holes are evenly distributed in a circular shape on the front of the limiting rod. The limiting rod cooperates with a fixed seat, and the fixed seat is slidably connected to the limiting rod. A grinding drill bit is fixedly connected to the front end face of the fixed seat, and a fixing mechanism is provided on the fixed seat.

[0004] Regarding the above-mentioned related technologies, the inventor believes that by extending the grinding drill bit and the rotating shaft into the interior of the stainless steel pipe, and driving the rotation of the grinding drill bit by rotating the rotating shaft, the inner wall of the stainless steel pipe can be ground. Since one end of the rotating shaft is connected to the output end of the motor and the other end is connected to the grinding drill bit, the end close to the grinding drill bit cannot be supported during use, and in order to reduce the deformation of the rotating shaft, the rotating shaft cannot be set to a longer length, so that the entire device cannot meet the requirements of grinding the inner wall of a longer stainless steel pipe, resulting in poor applicability of the entire grinding device.

[0024] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0025] See also Figure 1-4 A polishing device for stainless steel precision casting includes a fixing mechanism 1, which includes a support beam 101. A vertical plate 102 is symmetrically fixedly connected to the top of the support beam 101. The setting of the support beam 101 can provide support for the vertical plate 102. A support roller 103 is symmetrically rotatably connected between the two groups of vertical plates 102. The setting of the support roller 103 can provide support for the stainless steel pipe to be polished. Sliding blocks 105 are slidably connected to the inside of the two groups of vertical plates 102. A first hydraulic rod 106 is fixed through the inside of the vertical plates 102. The output ends of the two groups of first hydraulic rods 106 are respectively fixedly connected to the two groups of sliding blocks 105. A pressure roller 104 is rotatably connected between the two groups of sliding blocks 105. The setting of the first hydraulic rod 106 is used to drive the sliding block 105 and the pressure roller 104 to move up and down when starting work, so that the pressure roller 104 can compress and limit stainless steel pipes of different diameters.

[0026] A motor 107 is fixedly connected to one side of a set of sliding blocks 105 away from the pressure roller 104. The output end of the motor 107 is fixedly connected to one end of the pressure roller 104. The motor 107 is configured to drive the pressure roller 104 to rotate during startup, and when the pressure roller 104 rotates, the compressed stainless steel pipe can be rotated accordingly. The grinding mechanism 2 includes winches 201 symmetrically fixedly connected to both sides of the top of the support beam 101. The output ends of the two sets of winches 201 are fixedly connected to steel cables 202. The winches 201 are configured to reel in or unreel the steel cables 202 during startup. The opposite sides of the two sets of steel cables 202 are fixedly connected to hook rings 204 and C-shaped hooks 203, respectively. The C-shaped hooks 203 can be hooked with the hook rings 204, thereby connecting the two sets of steel cables 202. The outer thread of the C-shaped hook 203 is connected to the internal threaded tube 205, and the internal threaded tube 205 can be screwed to cover the opening of the C-shaped hook 203, thereby reducing the possibility of the hook ring 204 being separated from the C-shaped hook 203.

[0027] The support plate 109 is symmetrically connected to one side of the support beam 101 for rotation. The bottoms of the two groups of support plates 109 are fixedly connected to the base 108. The top side of the base 108 is rotatably connected to the second hydraulic rod 110. The output end of the second hydraulic rod 110 is rotatably connected to the support beam 101. The second hydraulic rod 110 is set to pull the support beam 101 to rotate when starting work, so that the support beam 101 and the stainless steel pipe pressed by the pressure roller 104 can be rotated and tilted accordingly, so that the stainless steel pipe can be adjusted to tilt when the C-shaped hook 203 and the steel cable 202 connected to the C-shaped hook 203 are passed through the stainless steel pipe, and then the C-shaped hook 203 is inserted from the higher end of the tilted stainless steel pipe, and the gravity of the C-shaped hook 203 is used to slide out from the lower part of the stainless steel pipe, making the insertion of the C-shaped hook 203 more convenient. At the same time, it is also convenient to dump out the debris remaining on the inner wall of the stainless steel pipe after grinding. A chip discharge port 112 is provided on one side of the support beam 101 close to the support plate 109 . The chip discharge port 112 is provided to facilitate the discharge of chips dropped from one end of the stainless steel pipe.

[0028] A support column 111 is symmetrically fixedly connected to the other side of the bottom of the support beam 101. Both sets of support columns 111 abut against the base 108. The provision of the support columns 111 can provide auxiliary support for the support beam 101. A fixed column 206 is fixedly connected to the outside of one side of the steel cable 202. An arc-shaped grinding block 209 is symmetrically and detachably connected to the outside of the fixed column 206. The fixed column 206 is set to move synchronously with the steel cable 202, and drives the arc-shaped grinding block 209 to move accordingly, so that the arc-shaped grinding block 209 can grind the inner wall of the stainless steel pipe as it moves along the inner wall of the stainless steel pipe. The outer side of the fixed column 206 is symmetrically provided with an arc-shaped connecting block 207, and the interior of the two groups of arc-shaped connecting blocks 207 are symmetrically threaded with fixing bolts 208. Each group of fixing bolts 208 is threadedly connected to the fixed column 206, and the two groups of arc-shaped grinding blocks 209 are respectively fixedly connected to the two groups of arc-shaped connecting blocks 207. The setting of the fixing bolts 208 can connect and fix the fixed column 206 and the arc-shaped connecting block 207, thereby achieving the fixation of the arc-shaped grinding block 209. At the same time, it is also convenient to replace the arc-shaped grinding blocks 209 with different outer diameters to adapt to the grinding of the inner wall of stainless steel pipes with different inner diameters.

[0029] A curved brush 210 is fixedly connected to one side of the outer wall of the curved connecting block 207. The curved brush 210 is arranged to move synchronously with the fixed column 206, thereby brushing and cleaning the inner wall of the stainless steel pipe. The two sets of vertical plates 102 are provided with support frames 211 fixedly connected to the support beam 101 on the opposite sides. The interiors of the two sets of support frames 211 are slidably connected to the sliding seats 212. The bottoms of the two sets of sliding seats 212 are rotatably connected to the pulleys 213. The two sets of steel cables 202 pass around the outsides of the two sets of pulleys 213 respectively. The pulleys 213 are arranged to guide the sliding seats 212. The tops of the two sets of sliding seats 212 are rotatably connected with adjusting screws 214, and the two sets of adjusting screws 214 are respectively threadedly connected to the two sets of support frames 211. The setting of the adjusting screws 214 can drive the sliding seat 212 and the pulley 213 to move up and down when rotating, thereby driving the steel cable 202 and the fixed column 206 to move up and down accordingly, so as to adjust the fixed column 206 to be coaxial with the stainless steel pipe, so as to facilitate the grinding of stainless steel pipes of different diameters.

[0030] In this embodiment, the hoist 201 is a prior art and will not be described in detail here.

[0031] When in use, the stainless steel pipe to be polished is placed between the two sets of support rollers 103 so that the two sets of support rollers 103 can support the stainless steel pipe, and the first hydraulic rods 106 on both sides are activated, so that the first hydraulic rods 106 on both sides drive the sliding block 105 and the pressure roller 104 to move downward until the pressure roller 104 presses the stainless steel pipe, and then the second hydraulic rod 110 is activated, so that the second hydraulic rod 110 pushes the support beam 101 to rotate, thereby adjusting the stainless steel pipe to an inclined state, and the C-shaped hook 203 and the steel cable 202 connected to the C-shaped hook 203 are inserted into the interior of the stainless steel pipe from one side of the stainless steel pipe, so that the C-shaped hook 203 and the steel cable 202 corresponding to the C-shaped hook 203 pass through the interior of the stainless steel pipe, and then the C-shaped hook 203 is hooked with the hook ring 204, and then the internal threaded tube 205 is twisted until the internal threaded tube 205 moves to close the C-shaped hook 203, and then the winch on one side is activated. 201, so that the winch 201 reels the corresponding steel cables 202 until the two sets of steel cables 202 are adjusted to a tensioned state, and the second hydraulic rod 110 is started until the support beam 101 is driven to rotate to a horizontal state, and then the winches 201 on both sides are started, so that the winch 201 on one side reels the steel cables 202, and the winch 201 on the other side unwinds the steel cables 202, and they are performed alternately, thereby pulling the arc-shaped grinding block 209 to reciprocate inside the stainless steel pipe, thereby achieving grinding of the inside of the stainless steel pipe, and at the same time, the motor 107 can be started, so that the motor 107 can drive the pressure roller 104 to rotate when starting work, and the pressure roller 104 can drive the stainless steel pipe to rotate when rotating, thereby improving the grinding effect of the stainless steel pipe, and when the stainless steel pipe rotates, the arc-shaped brush 210 can brush the inner wall of the stainless steel pipe, thereby improving the cleanliness of the inner wall of the stainless steel pipe after grinding.
