Description

Technical Field

[0001] The utility model relates to a wheel hub surface paint spraying tool, belonging to the technical field of wheel hubs. Background Art

[0002] The wheel hub is a cylindrical metal component with the inner contour of the tire supporting the tire, and the center is mounted on the shaft. It is also called a rim, steel ring, wheel, and tire bell. There are many types of wheel hubs depending on diameter, width, molding method, and material. The wheel hub is also called a wheel rim. According to the characteristics and needs of different models, the surface treatment process of the wheel hub will also take different methods, which can be roughly divided into two types: baking paint and electroplating. The appearance of the wheel hub of ordinary models is less considered, and good heat dissipation is a basic requirement. The process basically adopts baking paint treatment, that is, spraying first and then electric baking. The cost is relatively economical and the color is beautiful and lasts for a long time. Even if the vehicle is scrapped, the color of the wheel hub remains unchanged. The surface treatment process of many Volkswagen models is baking paint.

[0003] In the manufacturing process of wheel hubs, in order to maintain the beauty of the wheel hubs and improve their heat dissipation effect, it is often necessary to spray a protective paint on their surface. At this time, a device for spraying the surface of the wheel hub is needed. However, when spraying the wheel hub, it is necessary to ensure that the wheel hub will not move. When the wheel hub shakes due to interference from external factors during painting, the wheel hub may be removed from the spraying range of the spraying device, resulting in the inability to perform normal spraying work. At the same time, as the position of the wheel hub changes, the paint surface sprayed on the wheel hub will become uneven, which in turn affects the normal spraying work of the wheel hub.

[0004] For this reason, a wheel hub surface paint spraying tool is proposed. Utility Model Content

[0005] In view of this, the utility model provides a wheel hub surface paint spraying tool to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial choice.

[0006] The technical solution of the utility model is implemented as follows: a wheel hub surface paint spraying tool, comprising a workbench, a wheel hub body is arranged on the top of the workbench, a top plate is arranged on the top of the workbench, support plates are fixedly installed on the left and right sides of the bottom of the workbench, a fixing mechanism is arranged at the bottom of the workbench, the fixing mechanism comprises a first servo motor and a gear ring, the first servo motor is located at the bottom of the workbench, the gear ring is located at the top of the workbench, the first movable plate is movably connected to the first movable plate on all sides of the surface of the gear ring through a rotating shaft, the tops of the four first movable plates are movably connected to the second movable plates with a rotating shaft, the bottoms of the four second movable plates are movably connected to moving blocks through a rotating shaft, the outer sides of the four moving blocks are fixedly installed with connecting rods, the other ends of the four connecting rods are fixedly installed with clamps, and the inner sides of the four clamps are all in contact with the surface of the wheel hub body.

[0009] Further preferably, movable grooves are provided around the top of the workbench, and the bottoms of the four movable blocks are slidably connected to the inner cavities of the four movable grooves.

[0010] Further preferably, an adjustment mechanism is provided on the top of the workbench, and the adjustment mechanism includes a second servo motor, the second servo motor is fixedly installed on the top of the workbench, the output end of the second servo motor is fixedly connected to a turntable, the bottom of the turntable is fixedly installed with a vertical rod, the bottom of the vertical rod is fixedly installed with a spray device, and the output end of the spray device is connected to multiple nozzles.

[0011] Further preferably, electric telescopic rods are fixedly installed around the top of the workbench, and the top plate is fixedly installed on the tops of the four electric telescopic rods.

[0012] Further preferably, pads are fixedly mounted on the outer sides of the two support plates, and anchor bolts are threadedly connected to the front and rear sides of the tops of the two pads.

[0013] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0014] 1. The utility model sets a fixing mechanism so that the first servo motor can drive the gear to rotate, and through the cooperation of the gear ring, the first movable plate pulls the second movable plate and the moving block to move inward. At this time, the connecting rod and the clamp move inward synchronously, thereby completing the fixing of the hub body, ensuring that the hub body is in a fixed state during spraying, avoiding the overall shaking of the equipment due to interference from external factors during the spraying process, thereby causing the hub body to be separated from the spraying range of the spraying device, thereby affecting its normal fixing work, and improving the stability of the hub body during spraying.

[0015] 2. The utility model can transmit the kinetic energy of the first servo motor to the gear ring by setting the gear, and through the rotation of the gear ring, the first movable plate, the second movable plate and the moving block drive the connecting rod and the clamp to move inward, and fix the position of the wheel hub body, thereby improving the stability of the wheel hub body during spraying. By setting the limiting groove and the limiting block, the gear ring can be supported and its rotation direction can be limited to avoid deviation during movement, thereby affecting the normal fixation of the wheel hub body. By setting the moving groove, the moving block can be limited to avoid change of direction of the moving block during movement, thereby affecting the normal fixation of the wheel hub body. By setting the adjusting mechanism, the spraying device can be moved in a circle around the wheel hub body and its surface can be sprayed. Compared with the operator manually holding the spray device, the stability of the spray device when it moves can be improved, and the situation that the normal use of the hub body is affected due to uneven paint spraying when the spray device is spraying the hub body is avoided. By setting the electric telescopic rod, the overall height of the adjustment mechanism can be adjusted, which is convenient for spraying hub bodies of different types and sizes, and avoids the size of the hub body being too large or too small, resulting in the spray device being too far or too close to the hub body, and then affecting the normal spraying work. By setting the pad and the anchor bolts, the overall stability of the equipment can be improved, and it is avoided that the interference of external factors causes the equipment to shake or tip over, and then cause the hub body to move out of the spraying range of the nozzle, and then affect the normal spraying work of the hub body.

[0024] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0025] Example 1

[0026] like Figure 1-4As shown, it includes a workbench 1, a hub body 4 is arranged on the top of the workbench 1, a top plate 6 is arranged on the top of the workbench 1, support plates 7 are fixedly installed on the left and right sides of the bottom of the workbench 1, a fixing mechanism 2 is arranged at the bottom of the workbench 1, the fixing mechanism 2 includes a first servo motor 201 and a gear ring 203, the first servo motor 201 is located at the bottom of the workbench 1, the gear ring 203 is located at the top of the workbench 1, and the four sides of the surface of the gear ring 203 are movably connected with first movable plates 204 through rotating shafts, and the tops of the four first movable plates 204 are provided with rotating shafts. The shaft is movably connected to a second movable plate 205, and the bottoms of the four second movable plates 205 are movably connected to moving blocks 206 through rotating shafts. Connecting rods 207 are fixedly installed on the outer sides of the four moving blocks 206, and clamps 208 are fixedly installed on the other ends of the four connecting rods 207. The inner sides of the four clamps 208 are all in contact with the surface of the hub body 4. The first servo motor 201 is fixedly installed on the bottom of the workbench 1, and the output end of the first servo motor 201 is fixedly connected to a gear 202, and the surface of the gear 202 is meshed with the surface of the gear ring 203.

[0027] By setting up the fixing mechanism 2, the first servo motor 201 can drive the gear 202 to rotate, and through the cooperation of the gear ring 203, the first movable plate 204 pulls the second movable plate 205 and the moving block 206 to move inward. At this time, the connecting rod 207 and the clamp 208 move inward synchronously, thereby completing the fixing of the hub body 4, ensuring that the hub body 4 is in a fixed state during spraying, avoiding the overall shaking of the equipment due to interference from external factors during the spraying process, and then causing the hub body 4 to be out of the spraying range of the spraying device 304, thereby affecting its normal fixing work, and improving the stability of the hub body 4 during spraying.

[0028] Example 2

[0029] In one embodiment, a limit slot 210 is provided on the top of the workbench 1, and limit blocks 211 are fixedly installed around the bottom of the gear ring 203, and the four limit blocks 211 are slidably connected to the inner cavity of the limit slot 210. A moving slot 209 is provided around the top of the workbench 1, and the bottoms of the four moving blocks 206 are slidably connected to the inner cavities of the four moving slots 209. An adjustment mechanism 3 is provided on the top of the workbench 1, and the adjustment mechanism 3 includes a second servo motor 301, and the second servo motor 301 is fixedly installed on the workbench 1. At the top, the output end of the second servo motor 301 is fixedly connected to the turntable 302, the bottom of the turntable 302 is fixedly installed with a vertical rod 303, the bottom of the vertical rod 303 is fixedly installed with a spraying device 304, the output end of the spraying device 304 is connected to a plurality of nozzles 305, electric telescopic rods 5 are fixedly installed around the top of the workbench 1, the top plate 6 is fixedly installed on the top of the four electric telescopic rods 5, the outer sides of the two support plates 7 are fixedly installed with pads 8, and the front and rear sides of the tops of the two pads 8 are threadedly connected with anchor bolts 9.

[0030] By setting the gear 202, the kinetic energy of the first servo motor 201 can be transmitted to the gear ring 203, and through the rotation of the gear ring 203, the first movable plate 204, the second movable plate 205 and the moving block 206 drive the connecting rod 207 and the clamp 208 to move inward, and fix the position of the hub body 4, thereby improving the stability of the hub body 4 during spraying. By setting the limiting groove 210 and the limiting block 211, the gear ring 203 can be supported while limiting its rotation direction to avoid deviation during movement, thereby affecting the normal fixing of the hub body 4. By setting the moving groove 209, the moving block 206 can be limited to avoid the direction of the moving block 206 changing during movement, thereby affecting the normal fixing of the hub body 4. By setting the adjusting mechanism 3, the spraying device 304 can be moved circumferentially around the hub body 4. The wheel hub body 4 is moved and sprayed with paint. Compared with the operator manually holding the spraying device 304, the stability of the spraying device 304 when moving can be improved, and the situation that the normal use of the wheel hub body 4 is affected due to uneven paint spraying when the spraying device 304 is spraying the wheel hub body 4 can be avoided. By setting the electric telescopic rod 5, the overall height of the adjustment mechanism 3 can be adjusted, which is convenient for spraying wheel hub bodies 4 of different types and sizes, and the size of the wheel hub body 4 is avoided to be too large or too small, resulting in the spraying device 304 being too far or too close to the wheel hub body 4, thereby affecting the normal spraying work. By setting the pad 8 and the anchor bolt 9, the overall stability of the equipment can be improved, and the interference of external factors can be avoided, which causes the equipment to shake or tip over as a whole, thereby causing the wheel hub body 4 to move out of the spraying range of the nozzle 305, thereby affecting the normal spraying work of the wheel hub body 4.

[0031] When the utility model is working: after the hub body 4 is placed on the inner side of the clamp 208, the gear 202 drives the gear ring 203 to rotate through the output end of the first servo motor 201. At this time, the first movable plate 204 is flipped to the right side due to the rotation of the gear ring 203. With the flipping of the first movable plate 204, the second movable plate 205 is flipped to the right side and pulls the moving block 206 to move inward. With the movement of the moving block 206, the connecting rod 207 drives the clamp 208 to move inward synchronously, and the clamp 208 is fitted to the hub. The surface of the hub body 4 is fixed, and then the electric telescopic rod 5 drives the top plate 6 to move downward. With the movement of the top plate 6, the adjusting mechanism 3 moves downward synchronously as a whole, and makes the spraying device 304 and the nozzle 305 be on the outside of the top of the hub body 4. Then, the output end of the second servo motor 301 drives the turntable 302 to rotate. With the rotation of the turntable 302, the vertical rod 303 drives the spraying device 304 and the nozzle 305 to move in a circle along the top of the hub body 4, and starts to spray the surface of the hub body 4.

Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
