Description

Technical Field

[0001] This invention relates to the field of blind hole metal shavings cleaning technology, and more specifically, to an automatic cleaning device for blind hole metal shavings. Background Technology

[0002] A blind hole is a hole that does not penetrate the metal part during machining. While the metal shavings produced during machining are expelled from the hole along with the cutting tool, a small amount of small metal shavings still adhere to the sidewalls of the blind hole. If a tapping process is performed on the blind hole, even more small metal shavings will adhere to the thread teeth.

[0003] The existing cleaning method mainly uses ultrasonic water washing, which requires soaking the metal parts first, then cleaning them, rinsing them, and finally drying them. This method is time-consuming and labor-intensive, and it also generates wastewater, which is not conducive to environmental protection.

[0004] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide an automatic cleaning device for metal chips in blind holes. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic cleaning device for metal chips in blind holes to solve the above-mentioned problems.

[0006] To achieve the above objectives, an embodiment of the present invention provides the following technical solution:

[0007] An automatic cleaning device for blind hole metal chips includes a device box, a bellows cover is fixedly installed at the bottom of the device box, a workpiece body is placed below the bellows cover, and a blind hole is opened inside the workpiece body.

[0008] A blower cleaning assembly is disposed inside the device box. The blower cleaning assembly includes a servo motor and a sleeve. The output end of the servo motor is fixedly connected to a drive wheel. A driven wheel is sleeved on the sleeve. The drive wheel and the driven wheel are connected by a belt drive. A blower pipe is fixedly installed inside the sleeve. A dust removal needle is fixedly installed at the bottom of the blower pipe. An air blowing hole is opened at the bottom of one side of the dust removal needle.

[0009] A dust collection assembly is disposed on the top of the device housing and located on one side of the blower cleaning assembly.

[0010] As a further improvement of the present invention, the dust collection assembly includes a processing box, the processing box having an air guide cavity inside, and a separation cavity having a separation cavity inside the processing box and located on one side of the air guide cavity.

[0011] As a further improvement of the present invention, a fan is fixedly installed on one side of the inner wall of the separation chamber, and a filter screen is fixedly connected inside the separation chamber and on the side of the fan.

[0012] As a further improvement of the present invention, a ventilation pipe is provided inside the device box and on one side of the blower cleaning component, and an exhaust pipe is fixedly installed inside the air guide cavity. One end of the exhaust pipe is connected to the ventilation pipe, and the other end of the exhaust pipe is connected to the separation cavity.

[0013] As a further improvement of the present invention, a centrifuge cylinder is rotatably connected to one side of the filter screen, a servo motor is fixedly installed inside the centrifuge cylinder, and a collection hole is provided inside the processing box and below the centrifuge cylinder.

[0014] As a further improvement of the present invention, the outer surface of the centrifuge tube has a plurality of circular holes, which are distributed in a circumferential array, and an anti-clogging component is fitted on the centrifuge tube.

[0015] As a further improvement of the present invention, a dust collection box is movably installed at the bottom of the processing box and below the collection hole, an alarm is provided on the front of the dust collection box, and a warning component is provided inside the dust collection box.

[0016] As a further improvement of the present invention, the anti-clogging component includes a collar, the inner wall of which is provided with a cleaning brush, the cleaning brush being in contact with the outer surface of the centrifuge cylinder.

[0017] As a further improvement of the present invention, the warning component includes a receiving plate, which is slidably connected to both sides of the inner wall of the dust collection box, and a telescopic spring is fixedly connected between the bottom of the receiving plate and the bottom of the inner wall of the dust collection box.

[0018] As a further improvement of the present invention, a contact rod is fixedly connected to the bottom of the receiving plate, and a switch is fixedly connected to the bottom of the inner wall of the dust collection box, the switch being electrically connected to the alarm.

[0019] Compared with the prior art, the advantages of this invention are:

[0020] This solution incorporates a blower cleaning component, allowing the dust removal needle to penetrate deep into blind holes. A servo motor drives the needle to rotate, creating a spiral airflow within the hole. A robotic arm moves the needle up and down, blowing air at different depths within the blind hole to expel metal shavings. This rapid cleaning process eliminates the need for ultrasonic washing, soaking, and drying, saving time, simplifying operation, and enhancing equipment usability.

[0021] This solution incorporates a dust collection component. When the equipment extracts air containing metal shavings using vacuum negative pressure, a centrifuge can separate the metal shavings from the air, preventing them from being directly released into the air and improving the environmental friendliness of the equipment. The separated metal shavings can also be collected for subsequent unified processing, allowing for recycling and reuse, thus saving resources. Attached Figure Description

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0039] Example 1:

[0040] Please see Figure 1-8 An automatic cleaning device for blind hole metal shavings includes a device box 1. A bellows cover 4 is fixedly installed at the bottom of the device box 1. The bellows cover 4 is circular. A workpiece body 2 is placed below the bellows cover 4. The bellows cover 4 has a certain elasticity, which allows the bottom of the bellows cover 4 to tightly abut against the upper surface of the workpiece body 2. A blind hole 21 is opened inside the workpiece body 2. After the workpiece body 2 is processed, metal shavings will remain inside the blind hole 21.

[0041] The air-blowing cleaning component 3 is used to blow up metal shavings inside the blind hole 21. The air-blowing cleaning component 3 is located inside the device housing 1. It includes a servo motor 31 and a sleeve 33. The sleeve 33 connects to an air intake device. A drive wheel 32 is fixedly connected to the output end of the servo motor 31, allowing the servo motor 31 to easily rotate the drive wheel 32. A driven wheel 35 is fitted onto the sleeve 33. The drive wheel 32 and the driven wheel 35 are connected by a belt 36. The rotation of the drive wheel 32 easily drives the driven wheel 35 to rotate via the belt 36, and the rotation of the driven wheel 35 easily drives the sleeve 33 to rotate. A blower pipe 38 is fixedly installed inside the sleeve 33 for air intake. A dust removal needle 34 is fixedly installed at the bottom of the device. An air blowing hole 37 is opened on one side of the bottom of the dust removal needle 34. The air in the dust removal needle 34 can be blown out through the air blowing hole 37, thereby blowing up the metal shavings on the inner wall of the blind hole 21. The sleeve 33 can rotate to drive the dust removal needle 34 to rotate synchronously through the air blowing pipe 38. The top of the device box 1 is connected to a robot arm. The robot arm can pull and drive the dust removal needle 34 to move up and down. The rotation of the dust removal needle 34 can blow out a spiral air to blow out the metal shavings from the blind hole 21, thereby cleaning the blind hole 21. The bellows protective cover 4 can block the blown metal shavings to prevent the metal shavings from contaminating other parts of the workpiece body 2, ensuring the cleanliness of the workpiece body 2 and avoiding the need for secondary cleaning by the staff.

[0042] Dust collection assembly 5 is located on top of device box 1 and on one side of blowing cleaning assembly 3. A ventilation pipe 11 is provided inside device box 1 and on one side of blowing cleaning assembly 3. Dust collection assembly 5 is used to extract blown-out metal shavings through the ventilation pipe 11. Dust collection assembly 5 includes processing box 51. A protective door is rotatably connected to the front of processing box 51. The opening and closing of the protective door can be controlled by a buckle or other means to facilitate maintenance of the interior of processing box 51. A sealing gasket can be installed on the protective door to enhance the sealing of processing box 51. An air guide cavity 52 is provided inside processing box 51. An exhaust pipe 57 is fixedly installed inside air guide cavity 52 for air guidance. A separation section is provided inside processing box 51 and on one side of air guide cavity 52. A fan 54 is fixedly installed on one side of the inner wall of the separation chamber 53. An exhaust port is located on one side of the fan 54, and an exhaust port is located at the bottom of the fan 54. When the fan 54 is driven, it utilizes negative pressure to draw air. One end of the exhaust pipe 57 is connected to the ventilation pipe 11, and the other end is connected to the separation chamber 53. The fan 54 can extract metal shavings from the bellows cover 4 through the exhaust pipe 57. A filter screen 59 is fixedly connected inside the separation chamber 53 and to one side of the fan 54. The filter screen 59 is used to block and filter metal shavings, preventing them from being discharged into the external environment with the airflow, thus improving the environmental friendliness of the equipment. A centrifuge cylinder 55 is rotatably connected to one side of the filter screen 59. The outer surface of the centrifuge cylinder 55 has multiple round holes. Multiple circular holes are arranged in a circumferential array to enhance the airflow in the separation chamber 53. An anti-clogging component 6 is fitted onto the centrifuge cylinder 55 to clean the circular holes and prevent clogging. The anti-clogging component 6 includes a collar 61, with a cleaning brush 62 (a soft, high-density brush) on its inner wall. A miniature handle is fixedly connected to one side of the collar 61, allowing operators to pull the collar 61 to move the cleaning brush 62 to clean the centrifuge cylinder 55. The cleaning brush 62 contacts the outer surface of the centrifuge cylinder 55. A servo motor 510 is fixedly installed inside the centrifuge cylinder 55, driving it to rotate. The rotation of the centrifuge cylinder 55 agitates the air in the separation chamber 53, making the separation chamber 53... The airflow becomes a cyclone. When the fan 54 draws the metal shavings into the separation chamber 53, the metal shavings collide with the centrifuge drum 55 and are thrown off, thus separating the metal shavings from the airflow. A collection hole 56 is provided inside the processing box 51, below the centrifuge drum 55. A dust collection box 58 is movably installed at the bottom of the processing box 51, below the collection hole 56. The dust collection box 58 is connected to the separation chamber 53. The thrown-off metal shavings fall into the dust collection box 58 through the collection hole 56. The dust collection box 58 can be made of transparent material to facilitate observation of its remaining capacity. An alarm is installed on the front of the dust collection box 58, and a warning component 7 is installed inside the dust collection box 58. The warning component 7 is used to alert staff if they fail to observe the situation promptly.The system proactively prompts staff to clean the dust collection box 58. The warning component 7 includes a receiving plate 71, which is slidably connected to both sides of the inner wall of the dust collection box 58. A telescopic spring 72 is fixedly connected between the bottom of the receiving plate 71 and the bottom of the inner wall of the dust collection box 58. When a certain weight of metal shavings accumulates inside the dust collection box 58, the shavings can cause the receiving plate 71 to press the telescopic spring 72 downwards. A contact rod 73 is fixedly connected to the bottom of the receiving plate 71, and a switch 74 is fixedly connected to the bottom of the inner wall of the dust collection box 58. The switch 74 is electrically connected to an alarm. When the contact rod 73 touches the switch 74, it can activate the alarm to sound, reminding staff to clean the dust collection box 58, preventing the accumulation of metal shavings inside the box 51, and ensuring the dust collection effect of the box 51.

[0043] Working Principle: During use, the operator can mount the device on a robotic arm for automated operation. The robotic arm moves the device, inserting the dust removal needle 34 into the blind hole 21. Air is blown into the air pipe 38 through the air inlet device, and the air is blown out through the air outlet 37 through the dust removal needle 34. Simultaneously, the servo motor 31 drives the drive wheel 32 to rotate. The drive wheel 32 drives the driven wheel 35 to rotate through the belt 36. The driven wheel 35 rotates the sleeve 33, which drives the dust removal needle 34 to rotate through the air pipe 38. At the same time, the robotic arm can move the dust removal needle 34 up and down. The rotation of the dust removal needle 34 causes it to blow out a spiral airflow, blowing metal shavings out of the blind hole 21. Because the bellows cover 4 has a certain degree of resilience, the bottom of the bellows cover 4 can abut against the upper surface of the workpiece body 2. The bellows cover 4 can block the blown metal chips, preventing them from contaminating other parts of the workpiece body 2. At the same time, it drives the fan 54 to draw out the metal chips through the exhaust pipe 57. The filter screen 59 is used to filter the metal chips, preventing them from being discharged into the external environment along with the wind. Simultaneously, it drives the second servo motor 510, which drives the centrifuge drum 55 to rotate. The rotation of the centrifuge drum 55 can agitate the air in the separation chamber 53, making the air in the separation chamber 53 into a cyclone. When the fan 54 draws the air carrying the metal chips into the separation chamber 53, the metal chips hit the centrifuge drum 55 and are thrown off into the dust collection box 58, thus separating the metal chips from the air and facilitating the subsequent unified treatment of the metal chips.
