Abstract
Description
Technical Field
[0001] This utility model relates to the field of valve processing technology, specifically to a sandblasting device for valve surface treatment. Background Technology
[0002] As is well known, valves are important fluid control components in the industrial field, and their manufacturing process involves many key steps. Among them, surface treatment is a crucial step. During the production process, the surface of valves is often affected by processes such as casting, forging, and machining, resulting in surface roughness, impurities, or oxides. This not only affects the appearance quality of the valve but may also pose a potential threat to its performance and service life. Therefore, effectively treating the valve surface, such as removing impurities and improving surface smoothness, is an important task in the valve manufacturing process.
[0003] In the field of valve surface treatment, sandblasting equipment is a commonly used surface treatment device. Currently, the clamps in sandblasting equipment are mostly fixed structures or only have simple clamping functions. In actual use, due to the different shapes and sizes of valves, fixed clamps often obstruct local parts of the valve, resulting in that part not being effectively sandblasted, which affects the quality and effect of valve surface treatment. Summary of the Invention

Detailed Implementation
[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0028] See Figures 1-9A sandblasting device for valve surface treatment includes a body 1, which is a sandblasting machine with a sandblasting gun inside. A mounting platform 4 is bolted to the inside of the body 1. Two sets of movable plates 6 are slidably connected to the top of the mounting platform 4. Two sets of electric push rods 7 are installed inside the movable plates 6. The output end of the electric push rod 7 is keyed to a clamping block 5, and the top of the clamping block 5 passes through the movable plate 6. When the electric push rod 7 is turned on, its output end will drive the clamping block 5 to move. The opposing movement of the two sets of clamping blocks 5 will clamp part of the valve, fixing the valve to the top of the mounting platform 4. The mounting platform 4 is equipped with a drive assembly 3 and two sets of adjustment assemblies 2, and one side of the adjustment assembly 2 is fixedly connected to the bottom of the movable plate 6.
[0029] First, refer to Figures 3 to 7 In this embodiment, the adjustment component 2 includes a fixed plate 201 fixedly disposed inside the mounting platform 4 and a slider 207 slidably connected inside the mounting platform 4. The top of the slider 207 is fixedly connected to the bottom of the movable plate 6. Support plates 209 are provided on both sides of the slider 207. A top roller 212 is slidably connected inside the support plate 209. Two sets of movable plates 210 are slidably connected to the top of the fixed plate 201. A push plate 215 is slidably connected inside the movable plate 210. The side of the push plate 215 away from the movable plate 210 is rotatably connected to... On the outside of the top roller 212, a central shaft 213 is fixedly connected inside the push plate 215. Both ends of the central shaft 213 pass through the push plate 215. A pulley 214 is rotatably connected to the outside of the central shaft 213. A protrusion 208 is welded to the side of the fixed plate 201 near the slider 207. The outside of the pulley 214 contacts the outside of the protrusion 208. A disc is provided on the outside of the central shaft 213, and the disc is located on the side of the pulley 214 away from the push plate 215. Thus, the disc can block the pulley 214 and prevent the pulley 214 from being misaligned.
[0030] Specifically, to facilitate the misalignment of the movable plate 210, two sets of placement plates 211 are fixedly installed on the top of the fixed plate 201. A limit rod 204 is provided on one side of the placement plate 211. The movable plate 210 is slidably disposed on the outside of the limit rod 204. The limit rod 204 can be replaced with a polygonal limit plate with no less than three sides. By setting the parts that limit the movable plate 210, on the one hand, the limit rod 204 maintains the balance of the movable plate 210 during movement, preventing the movable plate 210 from becoming unbalanced and wobbling during movement, thus ensuring the normal movement of the movable plate 210. On the other hand, the limit rod 204 restricts the direction of the movable plate 210, preventing the device from failing due to misalignment of the movable plate 210, thus ensuring the normal use of the device.
[0031] Specifically, in order to enable the movable plate 210 to quickly return to its initial position, a mounting plate 205 is provided on the outside of the limiting rod 204. A first spring 203 is provided on one side of the mounting plate 205. The end of the first spring 203 away from the mounting plate 205 is fixedly installed on the outside of the movable plate 210. Thus, when the movable plate 210 is pushed, the first spring 203 will be squeezed by the movable plate 210. When the movable plate 210 is no longer pushed, the first spring 203 will bounce the movable plate 210 back to its initial position quickly.
[0032] Meanwhile, in order to prevent the push plate 215 from hitting the support plate 209 due to excessive back movement of the moving plate 210, a blocking plate 202 is provided on the outside of the limiting rod 204. The blocking plate 202 is located on the side of the moving plate 210 close to the placement plate 211. The blocking plate 202 can block the moving plate 210 and prevent the push plate 215 from hitting the support plate 209 due to excessive back movement of the moving plate 210.
[0033] Furthermore, in order to enable the slider 207 to move back quickly, a second spring 206 is provided on one side of the fixed plate 201. The end of the second spring 206 away from the fixed plate 201 is fixedly set to the slider 207. Thus, when the slider 207 is pushed, the second spring 206 will be stretched by the slider 207, and when the slider 207 is no longer pushed, the second spring 206 will bounce the slider 207 back to the initial position quickly.
[0034] Specifically, the bump 208 is semi-elliptical. The bump 208 can be replaced with two sets of triangular bumps, and the side with the longer width of the two sets of triangular bumps must be located in the middle of the fixing plate 201.
[0035] When the movable plate 210 is pushed, it will cause the push plate 215 to move laterally. The lateral movement of the push plate 215 will cause the central shaft 213 and the top roller 212 to move. The movement of the central shaft 213 will cause the pulley 214 to move. When the pulley 214 moves, it will be pushed by the protrusion 208, so that the pulley 214 pushes the push plate 215 by driving the central shaft 213. At this time, the push plate 215 will push the support plate 209 to move by pushing the top roller 212. The movement of the support plate 209 will cause the slider 207 to move. The movement of the slider 207 will cause the movable plate 6 to move, thereby changing the position of the top clamping block 5 of the movable plate 6.
[0036] Finally, see Figure 3 , Figure 4 and Figure 8In this embodiment, the drive assembly 3 includes a rotary motor 301 and a rotating column 304. Both the rotary motor 301 and the rotating column 304 are disposed inside the mounting platform 4. The rotary motor 301 is a bidirectional motor, and its output end can rotate forward or backward. The two ends of the rotating column 304 are respectively provided with a first threaded tube 303 and a second threaded tube 306. The threads on the outer sides of the first threaded tube 303 and the second threaded tube 306 are in opposite directions. The end of the first threaded tube 303 away from the rotating column 304 is keyed to the output end of the rotary motor 301. Sleeves 305 are screwed onto the outer sides of both the first threaded tube 303 and the second threaded tube 306. During rotation, the two sets of sleeves 305 will move towards each other or away from each other. Two sets of locking blocks 302 are provided on the outer side of the sleeves 305. The side of the locking block 302 away from the sleeves 305 is locked onto the outer side of the moving plate 210. After the rotary motor 301 is turned on, the output end of the rotary motor 301 will drive the first threaded tube 303 to rotate. The rotation of the first threaded tube 303 will drive the second threaded tube 306 to rotate by driving the rotating column 304. The rotation of the first threaded tube 303 and the second threaded tube 306 will drive the two sets of sleeves 305 to move linearly. The movement of the sleeves 305 will drive the locking blocks 302 to move. When the locking blocks 302 move, they will push the moving plate 210.
[0037] The sandblasting device for valve surface treatment, through the cooperation between pulley 214 and protrusion 208, when pulley 214 moves and is pushed by protrusion 208, top roller 212 will drive slider 207 to move by pushing support plate 209. The movement of slider 207 will change the position of clamping block 5, thereby avoiding the sandblasting part of the valve, reducing obstruction, improving the uniformity and quality of surface treatment, and the device can flexibly adjust the clamping point to improve the versatility of the equipment.
[0038] Working principle:
[0039] When using this valve surface treatment sandblasting device, first place the device in the desired location, then install the valve to be processed. Specifically, place the valve on the mounting platform 4, with multiple sets of clamping blocks 5 positioned on the outside of the valve. Then, activate multiple sets of electric push rods 7. The output of the electric push rods 7 will move the clamping blocks 5. When the two sets of clamping blocks 5 move towards each other, they will clamp part of the valve, fixing it to the top of the mounting platform 4, thus completing the valve installation.
[0040] Finally, after sandblasting most of the valve positions is completed, the clamping block 5 is moved to expose the covered area. Specifically, the operation is as follows: the rotary motor 301 is turned on, causing its output end to rotate the first threaded tube 303. The rotation of the first threaded tube 303 will drive the second threaded tube 306 to rotate via the rotating column 304. The rotation of the first threaded tube 303 and the second threaded tube 306 will cause the two sets of sleeves 305 to move linearly. The movement of the sleeves 305 will cause the clamping block 302 to move. When the clamping block 302 moves, it will push the moving plate 210. When the moving plate 210 is pushed, it will cause the push plate 215 to move laterally. The transverse movement of 15 will cause the central shaft 213 and the top roller 212 to move. The movement of the central shaft 213 will cause the pulley 214 to move. When the pulley 214 moves, it will be pushed by the protrusion 208, causing the pulley 214 to push the push plate 215 by driving the central shaft 213. At this time, the push plate 215 will push the support plate 209 to move by pushing the top roller 212. The movement of the support plate 209 will cause the slider 207 to move. The movement of the slider 207 will cause the movable plate 6 to move, thereby changing the position of the clamping block 5 at the top of the movable plate 6, exposing the position that was originally covered by the clamping block 5, and avoiding the situation where the valve part cannot be processed.
