[0016] Example 1
[0017] like Figures 1 to 4As shown, this utility model discloses a precision grinding and polishing device. The technical solution includes a housing 1, with extension plates 13 respectively provided at the left and right ends of the bottom of the housing 1. Mounting holes 14 are provided at the front and rear ends of the extension plates 13, allowing operators to easily fix the extension plates 13 at the bottom of the housing 1 using external fixing bolts. A housing cover 2 is rotatably mounted on the front end of the top of the housing 1. Rubber arm sleeves 7 are provided at the left and right ends of the interior of the housing 1, with the sleeve openings at the ends of the rubber arm sleeves 7 fixedly connected to the inner sides of glove openings 6 provided in the middle of the left and right sides of the housing 1. An observation window 12 is provided at the top front of the housing 1, and a supplementary light 15 is provided above the observation window 12 and fixedly mounted on... The supplementary light 15 located on the top front side of the interior of the housing 1 provides sufficient illumination for the grinding and polishing process, allowing operators to make timely adjustments to the mold through the observation window 12. A grinding and polishing unit 5 is located in the middle rear side of the housing 1. The grinding and polishing unit 5 includes a blowing pipe 51, a feeding pipe 52, a polishing sand hopper 53, an electric valve 54, and a nozzle 55. The blowing pipe 51 is fixedly installed on the top rear side of the housing 1, with a nozzle 55 at its front end, positioned at the top of the housing 1. The feeding pipe 52 is connected to the middle of the blowing pipe 51, and its top is fixedly connected to the discharge port at the center of the bottom of the polishing sand hopper 53 located on the top rear side of the housing 1. A detachable lid is provided on the top of the polishing sand hopper 53. The connecting screws at the four corners of the top are threaded into the screw holes at the four corners of the top of the polishing abrasive hopper 53, making it easy for the operator to remove the hopper cover and pour polishing abrasive into the polishing abrasive hopper 53. An electric valve 54 is installed in the middle of the discharge pipe 52. By opening the electric valve 54, the polishing abrasive in the polishing abrasive hopper 53 can be allowed to enter the blow pipe 51 under the action of gravity through the discharge pipe 52. The rear end of the blow pipe 51 can be connected to an external high-pressure gas delivery pipe, allowing the high-pressure gas entering the blow pipe 51 to evenly spray the polishing abrasive onto the surface of the mold to be polished through the nozzle 55. Driven by the high-speed airflow, the polishing abrasive rubs and collides with the mold surface, thereby removing tiny burrs from the mold surface, thus achieving… For the purpose of grinding and polishing, a discharge ramp 10 is provided at the bottom rear side of the interior of the housing 1, along with support rods 8 and arc-shaped support plates 9. Two support rods 8 are provided, symmetrically positioned on the top of the discharge ramp 10. Arc-shaped support plates 9 are fixedly installed on the top of each support rod 8. The support rods 8 and arc-shaped support plates 9 not only support the operator's arms, alleviating arm fatigue during mold grinding and polishing, but also provide temporary support for the placed mold. A discharge groove 11 is provided at the front end of the discharge ramp 10, and a collection frame 4 is provided below the discharge groove 11. Guide grooves 17 on the left and right sides of the collection frame 4 are slidably connected to guide rails 16 located at the bottom left and right sides of the interior of the housing 1.Waste and polishing abrasive generated during polishing slide down the discharge ramp 10 to the discharge trough 11 and finally fall into the collection frame 4. The guide grooves 17 on both sides of the collection frame 4 are slidably connected to the guide rails 16, making it easy for operators to remove the collection frame 4 for cleaning. The inner rear end of the collection frame 4 is provided with an installation groove 18, and the interior of the installation groove 18 is connected to the ventilation holes 20 arrayed at the rear end of the collection frame 4. A breathable sponge pad 19 is fixedly installed on the inner side of the installation groove 18. The breathable sponge pad 19 blocks the polishing abrasive and waste, allowing only gas to be discharged outward through the ventilation holes 20, thereby protecting the working environment from pollution by polishing abrasive and waste. The system also includes a controller 3, which is located on the top right side of the front of the housing 1. The output of the controller 3 is electrically connected to the input of the electric valve 54 and the supplementary light 15. The input of the controller 3 is electrically connected to the output of an external power supply. The controller 3 allows operators to easily control the opening status of the electric valve 54 and the opening or closing of the supplementary light 15. ,
[0018] The working principle of this utility model is as follows: When grinding and polishing a mold is required, the operator first opens the box cover 2 and places the mold to be ground and polished on the arc-shaped support plate 9 at the top of the support rod 8. Then, the operator can insert their arm into the rubber arm sleeve 7 inside the box 1 through the glove opening 6 to prepare for the grinding and polishing operation. The rubber arm sleeve 7 not only ensures the safety of the operator's hands and arms but also allows them to directly touch and pick up the mold for precise adjustments. Next, the operator activates the electric valve 54 through the controller 3 and controls the opening degree of the valve plate of the electric valve 54. This allows the polishing abrasive in the polishing abrasive hopper 53 to enter the interior of the blowing pipe 51 through the feed pipe 52 under the action of gravity. The rear end of the blowing pipe 51 can be connected to an external high-pressure gas delivery pipe, allowing the high-pressure gas entering the blowing pipe 51 to... Polishing abrasive is evenly sprayed onto the surface of the mold to be polished through nozzle 55. Driven by high-speed airflow, the polishing abrasive rubs and collides with the mold surface, thereby removing tiny burrs and achieving the purpose of polishing. At the same time, the operator can turn on the supplementary light 15 through the controller 3 to provide sufficient light for the polishing process, allowing the operator to make timely adjustments to the mold through the observation window 12. Finally, the waste and polishing abrasive generated during the polishing process slide down the discharge ramp 10 to the discharge trough 11 and eventually fall into the collection frame 4, so that the subsequent operators can process the waste and polishing abrasive collected inside. Meanwhile, the breathable sponge pad 19 in the mounting groove 18 on the rear side of the collection frame 4 can block the polishing abrasive and waste, allowing only gas to be discharged outward through the vent 20, thereby protecting the working environment from pollution by polishing abrasive and waste.
