Technical Field

[0001] This utility model belongs to the field of rice cooker inner pot polishing technology, specifically relating to a machine tool chip removal device. Background Technology

[0002] After the inner pot of the rice cooker is formed, the workers need to polish its surface. When polishing the inner wall of the rice cooker, the flying dust can be intercepted by the structure of the inner pot itself. However, when polishing the outer wall of the rice cooker, the flying dust is unobstructed and will directly fly onto the machine tool table and into the air of the processing workshop. In particular, the fine dust can cause damage to the machine tool and the workers. Utility Model Content

[0003] This utility model provides a machine tool chip removal device, which has the feature of being able to centrally remove the powder and chips generated during the grinding process of the inner pot of a rice cooker.

[0018] Please see Figures 1-4The present invention provides the following technical solution: a machine tool chip removal device, including a grinding positioning turntable body 1, a chip interception frame 2 on the outer side of the grinding positioning turntable body 1, an inclined guide plate 21 fixedly connected to the bottom end of the chip interception frame 2, a cover 3 at the top opening of the chip interception frame 2, an elastic base plate 31 below the cover 3, an exhaust pipe 32 fixedly connected to the bottom end of the elastic base plate 31, an outer support ring 33 below the cover 3, the outer support ring 33 fixedly connected to the elastic base plate 31, a cover ring 34 fixedly connected to the side wall of the outer support ring 33, an "L"-shaped top rod 4 below the exhaust pipe 32, and a connecting hose 5 fixedly connected to the top end of the exhaust pipe 32.

[0019] In this implementation plan: the grinding positioning turntable body 1 is the existing rice cooker inner pot grinding turntable. The folded pipe 51 is connected to the negative pressure device, which draws in air. The air at the openings of the cover 3 and the elastic base plate 31 moves through the exhaust pipe 32 connected to the hose 5 and the folded pipe 51. In the initial state, the adjusting telescopic rod 22 is in the retracted state, which drives the dust interception frame 2 and the inclined guide plate 21 to move downward. The cover 3, the elastic base plate 31 and the exhaust pipe 32 follow the dust interception frame 2 downward and flip upward under the limiting action of the "L"-shaped top rod 4 and the soft pad 41. The top opening of the dust interception frame 2 is in an unobstructed state. The worker installs the rice cooker inner pot to be ground on the top of the grinding positioning turntable body 1. During grinding, the output axis of the adjusting telescopic rod 22 is lifted upward, which drives the dust interception frame 2 and the inclined guide plate 21 to move upward. The cover 3, the elastic base plate 31 and the exhaust pipe 32 follow the dust interception frame 2 downward and flip upward under the limiting action of the "L"-shaped top rod 4 and the soft pad 41. The top opening of the dust interception frame 2 is in an unobstructed state. The worker installs the rice cooker inner pot to be ground on the top of the grinding positioning turntable body 1. During grinding, the output axis of the adjusting telescopic rod 22 is lifted upward, which drives the dust interception frame 2 and the inclined guide plate 21 to move upward. The cover 3, the elastic base plate 31 and the soft pad 41 flip upward. 1. The exhaust pipe 32 flips downward to cover the top opening of the dust interception frame 2. During the polishing of the rice cooker inner pot, the dust splashed laterally is intercepted by the dust interception frame 2 and falls to the top of the inclined guide plate 21. The dust that escapes upward is intercepted by the shielding cover 3 and the elastic bottom plate 31. The dust that escapes through the gap between the inner wall of the dust interception frame 2 and the shielding cover 3 is absorbed by negative pressure. The dust is absorbed along with the airflow and discharged into the folded pipe 51 through the connecting hose 5. The airflow can drive the elastic bottom plate 31 to shake during the rapid flow of the airflow in the gap between the shielding cover 3 and the elastic bottom plate 31, so as to shake off the dust attached to the bottom of the elastic bottom plate 31. With the interception of dust by the shielding ring 34, the distance that the dust escapes to the processing table after falling downward is increased, so that the escaped dust can be absorbed by negative pressure within the distance, which can prevent the dust from falling onto the processing table after the shielding cover 3 and the elastic bottom plate 31 are flipped open.

[0020] Two symmetrically distributed adjustable telescopic rods 22 are fixedly connected to the bottom end of the inclined guide plate 21. By setting the adjustable telescopic rods 22, the height of the dust interception frame 2 and the inclined guide plate 21 can be adjusted so that personnel can easily take out and put in the rice cooker inner pot. The up and down movement of the dust interception frame 2 can be used in conjunction with the "L"-shaped top rod 4 to adjust the opening and closing of the exhaust pipe 32.

[0021] A support rod 321 is fixedly connected to the inner wall of the exhaust duct 32. The top end of the support rod 321 is fixedly connected to the bottom end of the shielding cover 3. A torsion spring connecting seat 322 is fixedly connected to one end of the exhaust duct 32. The torsion spring connecting seat 322 is fixedly connected to the inner wall of the dust interception frame 2. The exhaust duct 32 is hinged to the dust interception frame 2 through the torsion spring connecting seat 322. A connecting post 331 is fixedly connected to the top end of the outer support ring 33. The connecting post 331 is fixedly connected to the shielding cover 3. By setting the support rod 321, the shielding cover 3 can be adjusted. The support rod 321 is designed to provide a distance between the cover 3 and the elastic base 31, and the size of the support rod 321 is smaller than the inner diameter of the exhaust duct 32, so as not to cause blockage at the opening of the exhaust duct 32. The exhaust duct 32 can be flipped by setting the torsion spring connecting seat 322, and the initial force for the exhaust duct 32 to flip downward is provided. The cover 3 and the elastic base 31 can be connected by setting the connecting column 331, so as to support the outer edge of the elastic base 31 with the help of the outer support ring 33.

[0022] Several elastic connecting strips 35 are fixedly connected to the top of the elastic film 31, and the elastic connecting strips 35 are fixedly connected to the cover 3. By setting the elastic connecting strips 35, the middle part of the elastic film 31 can be supported, preventing the middle part of the elastic film 31 from sinking downwards significantly, and the elasticity of the elastic connecting strips 35 will not hinder the shaking of the elastic film 31.

[0023] Both the cover 3 and the elastic base 31 are provided with a grinding roller clearance groove 36, and both the cover 3 and the elastic base 31 are provided with a rotating seat clearance groove 37. By setting the grinding roller clearance groove 36, the grinding roller can be clearanceed, and the rotating seat clearance groove 37 can clearance the torsion spring connecting seat 322, so that the cover 3 can be flipped smoothly.

[0024] The top of the “L”-shaped top rod 4 is fixedly connected to a soft pad 41, which is in contact with the bottom of the exhaust pipe 32. By setting the soft pad 41, the direct hard contact between the “L”-shaped top rod 4 and the exhaust pipe 32 can be avoided, which would cause the cover 3 and the elastic bottom plate 31 to collide and be damaged when they are flipped.

[0025] A folded pipe 51 is fixedly connected to the bottom end of the inclined guide plate 21, and a dust filter chamber 52 is fixedly connected to the bottom end of the connecting hose 5. The dust filter chamber 52 is fixedly connected to the folded pipe 51. By setting the folded pipe 51, dust in the gas can be filtered. The dust filter chamber 52 can easily adsorb the dust that settles inside the dust interception frame 2, so that the dust is concentrated in the folded pipe 51. After the staff opens the side wall opening of the folded pipe 51, the dust in the folded pipe 51 can be cleaned.

[0026] The working principle and usage process of this utility model: The folded pipe 51 is connected to the negative pressure device. The negative pressure device draws in air. The air at the openings of the cover 3 and the elastic base 31 moves through the exhaust pipe 32 connected to the hose 5 and the folded pipe 51. In the initial state, the telescopic rod 22 is in the retracted state, which drives the dust interception frame 2 and the inclined guide plate 21 to move downward. The cover 3, the elastic base 31 and the exhaust pipe 32 follow the dust interception frame 2 downward and flip upward under the limiting action of the "L"-shaped top rod 4 and the soft pad 41. The top opening of the dust interception frame 2 is in an unobstructed state. The worker installs the rice cooker inner pot that needs to be polished on the top of the polishing positioning turntable body 1. When polishing is in progress, the output axis of the telescopic rod 22 is lifted upward, which drives the dust interception frame 2 and the inclined guide plate 21 to move upward. The cover 3, the elastic base 31, and the exhaust pipe 32 flip downwards to cover the top opening of the dust interception frame 2. During the polishing of the rice cooker inner pot, the dust splashed sideways is intercepted by the dust interception frame 2 and falls to the top of the inclined guide plate 21. The dust that escapes upwards is intercepted by the cover 3 and the elastic base 31. The dust that escapes through the gap between the inner wall of the dust interception frame 2 and the cover 3 is adsorbed by negative pressure. The dust is absorbed along with the airflow and discharged into the folded pipe 51 through the connecting hose 5. As the airflow flows rapidly through the gap between the cover 3 and the elastic base 31, it causes the elastic base 31 to shake, so as to shake off the dust attached to the bottom of the elastic base 31. After the dust enters the folded pipe 51 and is filtered, the staff opens the side opening of the folded pipe 51 to clean the dust in the folded pipe 51.
