Description

Technical Field

[0001] This utility model relates to the field of impeller surface treatment technology, specifically to an electrophoresis fixture for impeller surface treatment. Background Technology

[0002] An impeller is a special wheel with blades that can drive the flow of air or fluid through rotation. Generally, after impellers are cast, they need to undergo surface treatment to increase their wear resistance and corrosion resistance. Existing impeller surface treatment processes include surface spraying, surface electroplating, and electrophoresis.

[0003] Currently, when performing electrophoresis on the surface of impellers, the impellers are usually fixed by a bracket, and then transported to the electrophoresis pool by a conveyor. During electrophoresis, bubbles are easily generated on the surface of the impeller, and electrophoresis is also performed on the shaft hole where the impeller is assembled. Electrophoresis on the shaft hole of the impeller assembly affects the overall size, which is not conducive to the subsequent assembly of the impeller, and it is not convenient to place and fix impellers of different sizes. Therefore, there are certain limitations in the electrophoresis of impellers.

[0004] Therefore, we propose an electrophoresis fixture for impeller surface treatment to address the problems mentioned above. Utility Model Content

Currently, when performing electrophoresis on the surface of impellers, the impeller is usually fixed by a bracket and transported to the electrophoresis pool by a conveyor.

[0025] By adopting the above technical solution, the movable seat can be fixed after the mounting seat is fixed.

[0026] Compared with the prior art, the beneficial effects of this utility model are: the electrophoresis fixture for impeller surface treatment has positioning components set inside and outside the hollow rod, which allows multiple impeller bodies to be strung together through the hollow rod, and multiple impeller bodies can be electrophoresed at the same time. Furthermore, the electrophoretic water is introduced through the structure of the impeller body itself, reducing the generation of bubbles. It can also support and position impeller bodies of different sizes, thus improving the overall applicability.

[0027] 1. Positioning components are installed inside and outside the hollow rod. After capacitively mounting multiple impeller bodies, the mounting base is removed, and the cylinder is fitted over the hollow rod, ensuring the mounting sealing gasket at the top of the cylinder contacts the baffle. Then, the impeller body and cylinder are fitted in sequence. After the impeller body is installed, the mounting base is secured with a fixing nut. The entire assembly can then be placed on the conveying equipment via the hook above the hollow rod. The weight of the impeller body pushes the movable rod to slide inside the hollow rod. The movement of the movable rod drives several sets of connecting rods to rotate. The rotation of these connecting rods pushes two arc-shaped plates away from each other. During the movement, the arc-shaped plates cause the limiting rod to slide in the sliding groove for support, allowing the two arc-shaped plates to move apart. The rubber plate on the plate fits into the mounting holes on the impeller body. The rubber plate can deform to accommodate impeller bodies of different sizes. Under the action of gravity, the impeller body can compress the mounting gasket on the cylinder. The mounting gasket and the fixed gasket have cavities inside. The whole is made of rubber material, which allows the mounting gasket to deform. After the whole body deforms, it can seal the assembly of impeller bodies of different sizes. The positioning component allows multiple impeller bodies to be strung together through the hollow rod. Multiple impeller bodies can be electrophoretically treated at the same time. The electrophoretic water is introduced through the structure of the impeller body itself to reduce the generation of air bubbles. It can also support and position impeller bodies of different sizes, improving the overall applicability.

[0028] 2. When sealing the assembly of impeller bodies of different sizes, if the inside of the cylinder does not contact the hollow rod or the arc-shaped plate, the cylinder is prone to displacement. When displacement occurs, the gravity of the upper impeller body compresses the sealing gasket at the top of the cylinder, causing deformation. After the sealing gasket deforms, it can push the mounting sleeve and the moving rod to slide on the positioning block. After the moving rod moves, it can push the rotating rod to rotate on the mounting bracket through the sliding of the ball and the rotating rod. Since the deformation of the sealing gasket is not too large, the displacement of the moving rod is small. However, when the moving rod moves and pushes the rotating rod to rotate, the rotating rod... With one side of the mounting bracket as the axis, the end of the rotating rod closer to the moving rod rotates with a smaller amplitude, while the end of the rotating rod farther from the moving rod rotates with a larger amplitude. This allows the movable sleeve to slide on the fixed rod after the rotating rod rotates, thereby pushing the mounting block to move. This, in turn, moves the sliding rod, allowing the two support sleeves to fit against the arc plate. The two sliding rods move at the same displacement, so that if the cylinder becomes skewed, the support sleeves can straighten the cylinder, preventing the skew from affecting the sealing of the impeller body assembly hole and avoiding electrophoresis on the impeller body assembly hole.

[0029] 3. When installing the mounting base, place the mounting base onto the movable rod so that the movable base is placed in the mounting groove. Then, tighten the fixing nut to move the mounting ring upward. After the mounting ring moves upward, it pushes the two support rods upward. At the same time, the support rods move upward and push the push rod to rotate. After the push rod rotates, it pushes the movable block to move, causing the positioning rod to move and compress the spring. This causes the positioning rod to engage with the positioning groove on the movable base, thus fixing the movable base on the mounting base. Subsequently, the gravity of the impeller body can drive the mounting base to move. The mounting base can then drive the movable rod to move, making it convenient for users to install and fix the mounting base and the movable base, thus improving convenience.

[0040] 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.

[0041] Please see Figures 1-9 This utility model provides a technical solution: an electrophoresis fixture for impeller surface treatment, including a hollow rod 1, and a plurality of impeller bodies 101 are sleeved on the outside of the hollow rod 1;

[0042] Also includes:

[0043] Mounting base 102 is located below hollow rod 1, and a fixing nut 103 is provided below mounting base 102. A baffle 104 is threadedly connected to the upper outer surface of hollow rod 1, and a fixing sealing gasket 1021 is fixedly installed on the top of mounting base 102.

[0044] Positioning component 2 is disposed inside and outside the hollow rod 1. Positioning component 2 includes movable rod 201.

[0045] The movable rod 201 is movably connected inside the hollow rod 1. Several limiting blocks 2011 are fixedly installed inside the hollow rod 1, and the movable rod 201 is slidably connected to the several limiting blocks 2011. The fixing nut 103 is threadedly connected to the movable rod 201. Meanwhile, movable grooves 202 are symmetrically opened on both sides inside the hollow rod 1, and arc-shaped plates 203 are movably connected inside both movable grooves 202.

[0046] A rubber plate 204 is fixedly installed on the side of two arc-shaped plates 203 that are far apart. Several limiting rods 206 are symmetrically installed on both sides of the two arc-shaped plates 203. Several sliding grooves 205 are opened inside the hollow rod 1 between the two movable grooves 202. The limiting rods 206 are slidably connected to the sliding grooves 205. At the same time, a connecting rod 207 is hinged to the side of the movable rod 201 near the upper side of several sets of limiting rods 206. The end of the connecting rod 207 away from the movable rod 201 is hinged to the arc-shaped plate 203. A cylinder 208 is sleeved on the outside of the hollow rod 1 between several impeller bodies 101. The two ends of the cylinder 208 are symmetrically installed with sealing gaskets 209. At the same time, a shell 210 is symmetrically connected through the upper part of the cylinder 208.

[0047] Example 1: As Figures 1-6As shown, positioning components 2 are set inside and outside the hollow rod 1. After capacitively mounting multiple impeller bodies 101, the mounting base 102 is removed, and the cylinder 208 is fitted onto the outside of the hollow rod 1, so that the mounting sealing gasket 209 at the top of the cylinder 208 contacts the baffle 104. Then, the impeller bodies 101 and the cylinder 208 can be fitted into the cylinders according to the steps. After the impeller bodies 101 are installed, the mounting base 102 is fixed by the fixing nut 103. The whole assembly can be placed on the conveying equipment through the hook above the hollow rod 1. Then, the gravity of the impeller bodies 101 can push the movable rod 201 to slide inside the hollow rod 1. After the movable rod 201 moves, it can drive several sets of connecting rods 207 to rotate. After the several sets of connecting rods 207 rotate, they can push the two arc plates 203 away from each other. During the movement, the arc plates 203 drive the limiting rod 206 to slide in the sliding groove 205 for support. The support allows the rubber plates 204 on the two arc-shaped plates 203 to fit into the mounting holes on the impeller body 101. The rubber plates 204 can deform to accommodate impeller bodies 101 of different sizes. Under the action of gravity, the impeller body 101 can compress the mounting gasket 209 on the cylinder 208. The mounting gasket 209 and the fixed gasket 1021 have cavities inside and are made of rubber material, allowing the mounting gasket 209 to deform. After overall deformation, it can seal the assembly of impeller bodies 101 of different sizes. The positioning component 2 allows multiple impeller bodies 101 to be connected in series through the hollow rod 1, enabling simultaneous electrophoresis of multiple impeller bodies 101. The structure of the impeller body 101 itself introduces electrophoretic water, reducing the generation of bubbles. It can also support and position impeller bodies 101 of different sizes, improving the overall applicability.

[0048] A sliding rod 211 is slidably connected inside the housing 210, and a support sleeve 212 is fixedly installed at one end of the sliding rod 211. A telescopic spring 213 is sleeved on the outer side of the sliding rod 211. At the same time, one end of the telescopic spring 213 is fixedly connected to the housing 210, and an installation block 214 is fixedly installed at the other end of the telescopic spring 213. The installation block 214 is fixedly connected to the sliding rod 211.

[0049] A positioning block 215 is fixedly installed on one side of the top of each of the two housings 210, and a moving rod 216 is slidably connected inside the positioning block 215. A mounting sleeve 219 is fixedly installed at one end of the moving rod 216. Meanwhile, a support frame 217 is slidably connected to the outside of the moving rod 216 away from the mounting sleeve 219. A connecting frame 218 is fixedly installed at the bottom of the support frame 217, and the connecting frame 218 is fixedly connected to the housing 210.

[0050] The end of the movable rod 216 away from the mounting sleeve 219 is hinged with a ball bearing 220, and mounting brackets 221 are symmetrically installed on both sides of the support frame 217, and a rotating rod 222 is hinged between the two mounting brackets 221. At the same time, the ball bearing 220 is rotatably connected to the rotating rod 222.

[0051] A fixing block 223 is symmetrically installed on one side of the rotating rod 222, and a fixing rod 224 is fixedly installed between the two fixing blocks 223. A movable sleeve 225 is movably connected to the outer side of the fixing rod 224. Meanwhile, a connecting block 226 is symmetrically hinged to both sides of the movable sleeve 225, and the connecting block 226 is fixedly connected to the mounting block 214.

[0052] Example 2: Figure 2 and Figures 5-8 As shown, when sealing the assembly of impeller bodies 101 of different sizes, the interior of the cylinder 208 does not contact the hollow rod 1 or the arc plate 203, making the cylinder 208 prone to displacement. When displacement occurs, the gravity of the upper impeller body 101 compresses the sealing gasket 209 at the top of the cylinder 208, causing deformation. After the sealing gasket 209 deforms, it can push the mounting sleeve 219 and the moving rod 216 to slide on the positioning block 215. After the moving rod 216 moves, it can push the rotating rod 222 to rotate on the mounting bracket 221 through the sliding of the ball bearing 220 and the rotating rod 222. Since the deformation of the sealing gasket 209 is not too large, the displacement of the moving rod 216 is small. When the moving rod 216 moves and pushes the rotating rod 222 to rotate, the rotation... The rotating rod 222 rotates with one side of the mounting bracket 221 as its axis. The end of the rotating rod 222 closer to the moving rod 216 rotates with a smaller amplitude, while the end of the rotating rod 222 further away from the moving rod 216 rotates with a larger amplitude. This allows the movable sleeve 225 to slide on the fixed rod 224 after the rotating rod 222 rotates, thereby pushing the mounting block 214 to move. This allows the sliding rod 211 to move, so that the two support sleeves 212 can fit against the arc plate 203. The two sliding rods 211 move at the same displacement, so that if the cylinder 208 becomes skewed, it can be straightened by the support sleeves 212, avoiding the skew from affecting the sealing of the impeller body 101 assembly hole and avoiding electrophoresis on the impeller body 101 assembly hole.

[0053] The top of the mounting base 102 is provided with a mounting groove 229, and the movable base 228 is adapted to the mounting groove 229. The movable rod 201 is movably connected to the mounting base 102. Meanwhile, rectangular grooves 230 are symmetrically provided on both sides inside the mounting base 102. Positioning rods 231 are slidably connected above the interior of the two rectangular grooves 230 inside the mounting base 102. Positioning grooves are symmetrically provided on both sides of the movable base 228, and the positioning rods 231 are engaged with the positioning grooves.

[0054] Compression springs 232 are fitted on the outer side of both positioning rods 231. One end of the compression spring 232 is fixedly connected to the rectangular groove 230, and a movable block 233 is fixedly installed on the other end of the compression spring 232. The movable block 233 is fixedly connected to the positioning rod 231. A push rod 234 is hinged to the bottom of the movable block 233. A support rod 235 is hinged to the end of each push rod 234 away from the movable block 233. The support rod 235 is slidably connected to the mounting base 102. At the same time, an mounting ring 236 is fixedly installed at the bottom end of the two support rods 235.

[0055] A return spring 227 is sleeved on the lower outer side of the movable rod 201. One end of the return spring 227 is fixedly connected to the hollow rod 1, and the other end of the return spring 227 is fixedly installed with a movable seat 228. The movable seat 228 is slidably connected to the movable rod 201.

[0056] Example 3: Figure 2 and Figure 9 As shown, when installing the mounting base 102, the mounting base 102 is placed on the movable rod 201, so that the movable seat 228 is placed in the mounting groove 229. Then, tightening the fixing nut 103 can drive the mounting ring 236 to move upward. After the mounting ring 236 moves upward, it pushes the two support rods 235 to move upward. At the same time, the support rods 235 can push the push rod 234 to rotate. After the push rod 234 rotates, it can push the movable block 233 to move, so that the positioning rod 231 moves to compress the compression spring 232, so that the positioning rod 231 engages with the positioning groove on the movable seat 228, so that the movable seat 228 is fixed on the mounting base 102. Then, the gravity of the impeller body 101 can drive the mounting base 102 to move. The mounting base 102 can drive the movable rod 201 to move, which makes it convenient for users to install and fix the mounting base 102 and the movable seat 228, improving convenience.

[0057] Working principle: When using this electrophoresis fixture for impeller surface treatment, firstly, according to Figures 1-9As shown, after capacitively mounting multiple impeller bodies 101, the mounting base 102 is removed, and the cylinder 208 is fitted over the hollow rod 1, so that the mounting sealing gasket 209 at the top of the cylinder 208 contacts the baffle 104. Then, the impeller bodies 101 and cylinder 208 can be fitted in sequence. After the impeller bodies 101 are installed, tightening the fixing nut 103 can drive the mounting ring 236 to move upward. After the mounting ring 236 moves upward, it pushes the two support rods 235 to move upward. At the same time, the support rods 235 can push the push rod 234 to rotate. After the push rod 234 rotates, it can push the movable block 233 to move, so that the positioning rod 231 moves and compresses the compression spring 232, so that the positioning rod 231 engages with the positioning groove on the movable seat 228, so that the movable seat 228 is fixed on the mounting base 102. Then, the gravity of the impeller body 101 can drive the mounting base 102 to move. Through the mounting base 102, the movable rod 201 can be moved, so that the whole assembly can be moved. The hook above the hollow rod 1 is placed on the conveying equipment. Then, the gravity of the impeller body 101 can push the movable rod 201 to slide inside the hollow rod 1. After the movable rod 201 moves, it can drive several sets of connecting rods 207 to rotate. After the several sets of connecting rods 207 rotate, they can push the two arc plates 203 away from each other. During the movement, the arc plates 203 drive the limiting rod 206 to slide in the sliding groove 205 for support, so that the rubber plate 204 on the two arc plates 203 fits into the mounting hole on the impeller body 101. The rubber plate 204 can deform and is suitable for impeller bodies 101 of different sizes. Under the action of gravity, the impeller body 101 can compress the mounting gasket 209 on the cylinder 208. The mounting gasket 209 and the fixed gasket 1021 have cavities inside and are made of rubber material, so that the mounting gasket 209 can deform. After the overall deformation, it can seal the assembly of impeller bodies 101 of different sizes.

[0058] When sealing the assembly points of impeller bodies 101 of different sizes, the interior of the cylinder 208 does not contact the hollow rod 1 or the arc plate 203. The cylinder 208 is prone to displacement. When displacement occurs, the gravity of the upper impeller body 101 compresses the sealing gasket 209 at the top of the cylinder 208, causing deformation. After deformation, the sealing gasket 209 can push the mounting sleeve 219 and the moving rod 216 to slide on the positioning block 215. After the moving rod 216 moves, it can push the rotating rod 222 to rotate on the mounting bracket 221 through the sliding of the ball bearing 220 and the rotating rod 222. Since the deformation of the sealing gasket 209 is not too large, the displacement of the moving rod 216 is small. When the moving rod 216 moves and pushes the rotating rod 222 to rotate, the rotation... With one side of the mounting bracket 221 as the axis, the end of the rotating rod 222 closer to the moving rod 216 rotates with a smaller amplitude, while the end of the rotating rod 222 further away from the moving rod 216 rotates with a larger amplitude. This allows the movable sleeve 225 to slide on the fixed rod 224 after the rotating rod 222 rotates, thereby pushing the mounting block 214 to move. This, in turn, moves the sliding rod 211, allowing the two support sleeves 212 to fit against the arc plate 203. The two sliding rods 211 move at the same displacement, so that if the cylinder 208 becomes skewed, it can be straightened by the support sleeves 212, preventing the skew from affecting the sealing of the impeller body 101 assembly hole and avoiding electrophoresis on the impeller body 101 assembly hole.
