Description

Technical Field

[0001] This invention belongs to the field of polishing technology for metal components, specifically relating to a polishing device for micro-precision metal components. Background Technology

[0002] Micro-precision hardware refers to tools (miniature springs, precision terminals, miniature stamped parts, miniature shafts, etc.) made from metals such as gold, silver, copper, iron, and tin through processing and casting. These tools are used to fix things, process objects, and for decoration. After micro-precision hardware is processed, there are fine burrs and machining marks on the surface. It is necessary to perform micro-grinding to ensure dimensional accuracy and surface finish.

[0003] However, existing polishing equipment lacks a debris removal structure, which makes the debris generated during the polishing of hardware parts easily fly away, affecting the subsequent cleaning pressure and easily causing injury to workers, bringing unnecessary trouble to users. Summary of the Invention

[0004] The purpose of this invention is to provide a grinding device for micro-precision hardware components, so as to solve the problem that it is not easy to clean up debris when grinding hardware components in the prior art.

[0005] To achieve the above objectives, the present invention provides a polishing device for micro-precision hardware components, comprising: an operating table, a chip removal mechanism, a filter assembly, and an intelligent control system;

[0006] The chip removal mechanism is fixed on the operating table. The chip removal mechanism includes a grinding disc, a suction hood, a delivery air pipe and an air pump. The suction hood is located above the grinding disc. The delivery air pipe is located between the suction hood and the air pump. The air pump is fixedly installed on the operating table. A drive motor is fixedly installed at the bottom of the operating table.

[0007] The filter assembly is installed on the air delivery pipe. The filter assembly includes a collection bottle and a filter plate. The filter plate is installed inside the air delivery pipe. The collection bottle is used to collect debris. A knocking component is provided above the filter plate.

[0008] The intelligent control system is embedded in the front of the operating table. The intelligent control system is electrically connected to the drive motor, air pump and striking component, and is used for automatic adjustment of the overall process parameters, monitoring of operating status and fault early warning.

[0009] In one or more embodiments of the present invention, a plurality of support legs are fixedly installed at the bottom of the operating table to support and fix the operating table, making it less prone to shaking or tilting, thereby facilitating the operator to perform fine polishing on the hardware parts. Specifically, anti-slip and shock-absorbing rubber pads are added to the bottom of the support legs to reduce vibration during equipment operation and prevent displacement or shifting of the hardware parts during polishing.

[0010] In one or more embodiments of the present invention, a protective cover is fixed on the operating table, the grinding disc is disposed inside the protective cover, and the suction hood is installed on the protective cover, and the protective cover and the suction hood are interconnected to reduce the splashing of debris and facilitate the rapid removal of debris.

[0011] In one or more embodiments of the present invention, a drive shaft is fixedly connected to the drive motor, and the top end of the drive shaft is fixedly connected to the grinding disc. By starting the drive motor, the drive shaft and the grinding disc are driven to rotate, so that the grinding disc can grind the hardware parts.

[0012] In one or more embodiments of the present invention, a fixed bearing is fixedly connected between the drive shaft and the operating table to fix the drive shaft, so that the drive shaft is not prone to shaking or tilting, thereby stably driving the grinding disc to rotate.

[0013] In one or more embodiments of the present invention, a fixed connecting pipe is fixed on the gas delivery pipe, and the collection bottle is threadedly connected to the fixed connecting pipe, so that the collection bottle can be easily installed on the fixed connecting pipe, avoiding the collection bottle from falling off, and making it convenient for workers to install and disassemble, thereby facilitating the cleaning of debris inside the collection bottle.

[0014] In one or more embodiments of the present invention, a tapping component is provided above the filter plate to facilitate workers to shake off debris from the filter plate.

[0015] In one or more embodiments of the present invention, the striking assembly includes: a striking rod and a cap; the striking rod extends through a delivery air pipe; the cap is fixed to the top end of the striking rod, and a support spring is fixedly connected between the cap and the delivery air pipe. By pulling the cap, the support spring generates a rebound force, and then the cap is released. The support spring pulls the cap, thereby pushing the striking rod to strike the filter plate, so that the debris attached to the filter plate can be shaken off.

[0016] In one or more embodiments of the present invention, the bottom end of the striking rod is semi-circular to facilitate striking the filter plate.

[0017] In one or more embodiments of the present invention, the filter plate is inclined to facilitate the falling of debris into the collection bottle. Preferably, the inclination angle is between 30° and 45°, and the collection bottle is made of PC material with capacity markings engraved on its outer wall for easy observation by the user.

[0018] In one or more embodiments of the present invention, the intelligent control system includes a main control module, a touch screen, a variable frequency speed control module, a sensing and detection unit, an audible and visual alarm unit, and an automatic screen cleaning drive module; the sensing and detection unit includes a speed sensor, a wind pressure sensor, a motor current sensor, and a material level sensor.

[0019] In one or more embodiments of the present invention, the automatic screen cleaning drive module is electrically connected to the striking component; when the wind pressure sensor detects that the negative pressure in the pipeline is lower than a preset value, the main control module starts the automatic screen cleaning drive module, which drives the striking rod to periodically strike the filter plate to shake off the accumulated debris.

[0020] In one or more embodiments of the present invention, the main control module pre-stores grinding process parameters corresponding to micro-precision hardware parts of various materials. After the operator selects the workpiece specifications through the touch screen, the main control module automatically adjusts the speed of the drive motor and the dust suction volume of the air pump through the frequency conversion speed control module.

[0021] Compared with the prior art, the beneficial effect of the present invention is that by setting up a debris cleaning structure, the debris generated during the grinding of hardware parts can be quickly cleaned up without splashing, thus reducing the risk of injury to workers.

Detailed Implementation

[0029] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0030] like Figures 1-5 As shown, a polishing device for micro-precision hardware components according to one embodiment of the present invention includes: an operating table 1, a chip removal mechanism 2, a filter assembly 3, and an intelligent control system.

[0031] like Figures 1-4 As shown, the chip removal mechanism 2 is fixed on the operating table 1. The chip removal mechanism 2 includes a grinding disc 201, a suction hood 205, a conveying air pipe 206, and an air pump 207. The suction hood 205 is located above the grinding disc 201, and the conveying air pipe 206 is located between the suction hood 205 and the air pump 207. The air pump 207 is fixedly installed on the operating table 1. The filter assembly 3 is installed on the conveying air pipe 206. The filter assembly 3 includes a collection bottle 301 and a filter plate 303. The filter plate 303 is installed inside the conveying air pipe 206, and the collection bottle 301 is used to collect debris. A drive motor 204 is fixedly installed at the bottom of the operating table 1, and a striking component is provided above the filter plate 303.

[0032] Specifically, the intelligent control system is embedded in the front of the operating table 1. The intelligent control system is electrically connected to the drive motor 24, the air pump 207, and the striking component, and is used for automatic adjustment of the overall process parameters, monitoring of operating status, and fault early warning.

[0033] The bottom of the operating table 1 is fixedly equipped with multiple support legs 101 to support and fix the operating table 1, preventing it from shaking or tilting, thus facilitating the fine polishing of hardware parts by the staff. Specifically, the bottom of the support legs 101 is equipped with anti-slip and shock-absorbing rubber pads to reduce vibration during equipment operation and prevent displacement of hardware parts during polishing.

[0034] like Figures 1-2 As shown, a protective cover 208 is fixed on the operating table 1, a grinding disc 201 is set inside the protective cover 208, and a suction hood 205 is installed on the protective cover 208. The protective cover 208 and the suction hood 205 are interconnected to reduce the splashing of debris and facilitate the rapid removal of debris.

[0035] like Figures 1-2 As shown, a drive motor 204 is fixedly installed at the bottom of the operating table 1, and a drive shaft 203 is fixedly connected to the drive motor 204. The top end of the drive shaft 203 is fixedly connected to the grinding disc 201. By starting the drive motor 204, the drive shaft 203 and the grinding disc 201 are driven to rotate, so that the grinding disc 201 can grind the hardware parts.

[0036] Specifically, a fixed bearing 202 is fixedly connected between the drive shaft 203 and the operating table 1 to fix the drive shaft 203, so that the drive shaft 203 is not prone to shaking or tilting, thereby stably driving the grinding disc 201 to rotate.

[0037] like Figures 1-4 As shown, a fixed connecting pipe 302 is fixed on the gas delivery pipe 206, and the collection bottle 301 is threadedly connected to the fixed connecting pipe 302, so that the collection bottle 301 can be easily installed on the fixed connecting pipe 302, preventing the collection bottle 301 from falling off, and making it convenient for workers to install and disassemble, thereby facilitating the cleaning of debris inside the collection bottle 301.

[0038] Specifically, a striking assembly is provided above the filter plate 303 to facilitate the removal of debris from the filter plate 303 by workers. The striking assembly includes a striking rod 305 and a cap 304; the striking rod 305 is installed through the air delivery pipe 206; the cap 304 is fixed to the top of the striking rod 305, and a support spring 306 is fixedly connected between the cap 304 and the air delivery pipe 206. By pulling the cap 304, the support spring 306 generates a rebound force. Then, by releasing the cap 304, the support spring 306 pulls the cap 304, which in turn pushes the striking rod 305 to strike the filter plate 303, thereby shaking off the debris attached to the filter plate 303.

[0039] like Figures 1-4 As shown, the bottom of the striking rod 305 is semi-circularly designed for easy tapping of the filter plate 303. The filter plate 303 is tilted to facilitate the falling of debris into the collection bottle 301. The tilt angle is between 30° and 45°. The collection bottle 301 is made of PC material, and its outer wall is engraved with capacity markings for easy observation by the user.

[0040] like Figure 5 As shown, the intelligent control system includes a main control module, a touch screen, a variable frequency speed control module, a sensor detection unit, an audible and visual alarm unit, and an automatic net clearing drive module; each module is integrated into the embedded control box on the front of the control panel 1, and the touch screen is exposed for easy visual operation by the operator.

[0041] like Figure 5 As shown, the main control module has multiple built-in grinding process programs and pre-stores standard grinding parameters for micro-precision hardware parts made of different materials such as stainless steel, copper, aluminum alloy, zinc alloy, and micro-hard alloy, including grinding speed, dust suction negative pressure, and automatic screen cleaning interval. Furthermore, the main control module is also used to simultaneously receive data collected from all sensors in real time and complete logical judgments.

[0042] like Figure 5As shown, the touch screen is a color LCD touchscreen with functions including: manual / automatic mode switching; one-click retrieval of workpiece material, model, and process parameters, and storage of custom parameters; real-time data display: grinding speed, pipeline negative pressure, motor current, equipment running time, and number of parts processed that day; fault record query and retrieval of historical processing data; customizable settings for automatic screen cleaning cycle, full material reminder threshold, and overload protection threshold; and manual single-step control: independent start of air pump 207 and independent start of automatic tapping component for convenient equipment maintenance and cleaning.

[0043] like Figure 5 As shown, the variable frequency speed control module corresponds to two independent variable frequency outputs for the drive motor 204 and the air pump 207, respectively. It receives instructions from the main control module to steplessly adjust the speed and suction air volume: high speed and large negative pressure are matched for hard, high-hardness micro hardware parts; low speed and medium negative pressure are matched for soft copper and aluminum micro parts to avoid over-grinding and causing the workpiece dimensions to exceed the tolerance.

[0044] like Figure 5 As shown, the sensing and detection unit includes: a speed sensor, a motor current sensor, and a material level sensor. The speed sensor is installed at the end of the drive shaft 203 to collect the actual rotation speed of the grinding disc 201 in real time and transmit it to the main control module; the motor current sensor is installed inside the suction hood 205 to detect the negative pressure suction force of the pipeline in real time and determine the degree of blockage of the filter plate 303; the material level sensor is installed on the inner wall of the collection bottle 301 to monitor the height of debris accumulation in real time and trigger a full material reminder when the bottle is full of debris.

[0045] like Figure 5 As shown, the audible and visual alarm unit includes a yellow warning light, a red fault light, and a buzzer alarm. Specifically, a yellow light with intermittent buzzer indicates slight filter blockage or the collection bottle is about to fill; a red light with continuous high-frequency buzzer indicates motor overload, severe filter blockage, or a safety malfunction due to the protective door being open, simultaneously locking the entire machine in operation.

[0046] like Figure 5 As shown, the data storage module automatically records daily operating time, total number of workpieces processed, fault type and occurrence time, and parameter adjustment records through a built-in local storage chip; it is equipped with a communication interface that can connect to the workshop production management system to realize the uploading of grinding equipment operation data, production capacity statistics, and remote traceability of equipment faults, adapting to the digital factory assembly line management.

[0047] like Figure 5 As shown, the automatic screen cleaning drive module: by setting an electromagnetic push rod that is electrically connected to the striking rod 305, after receiving the signal from the main control module, it periodically pushes the striking rod 305 to strike the filter plate 303, so as to realize the fully automatic shaking off the metal dust attached to the filter plate 303; the automatic screen cleaning cycle can be freely set on the touch screen, and the striking interval is automatically shortened when the filter plate 303 is blocked, so as to enhance the dust removal effect.

[0048] In practical use, the drive motor 204 is started to drive the drive shaft 203 and the grinding disc 201 to rotate, so that the grinding disc 201 can rotate, which makes it convenient for workers to perform fine grinding on the hardware. Before grinding, the air pump 207 is started, so that the air pump 207 can drive the air flow, so that the negative pressure suction force is generated below the air suction hood 205, and then the air is delivered outward through the air delivery pipe 206.

[0049] Therefore, when workers are polishing hardware parts, a strong suction force is generated below the suction hood 205, which allows the debris generated during polishing to be quickly sucked away, preventing debris from flying. After the debris is sucked away, it is transported through the air delivery pipe 206, and then when it passes through the filter plate 303, the debris in the gas is blocked and gradually slides into the collection bottle 301 for easy collection and cleaning. After processing, workers can pull the cap 304 and then release it. Through the pull of the support spring 306, the lower end of the striking rod 305 can strike the filter plate 303, causing the debris attached to the filter plate 303 to fall off, thus preventing clogging during subsequent use.

[0050] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0051] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
