[0001] The utility model relates to the technical field of bearing cutting processing devices, in particular to a chuck for preventing iron chips from splashing for bearing cutting. Background Art

[0002] The overall process of bearing cutting includes preparing raw materials, processing outer and inner rings, processing rollers and cages, assembling bearings, testing quality, and packaging for shipment. During the processing, it is necessary to select suitable materials, turn or cut to obtain the required size of inner and outer rings, and produce rollers and cages at the same time. After assembly, strict quality inspection is required to ensure that the product meets the requirements, and finally package and ship. The entire process requires strict quality control to ensure the quality and performance of the bearing.

[0003] During the bearing cutting process, metal chip splashing may cause a variety of adverse effects. First, it threatens the safety of operators. The splashing metal chips may cause damage to the eyes or skin. Secondly, metal chip splashing will affect the processing accuracy, scratch the bearing surface, and cause quality degradation. In addition, excessive metal chip accumulation will reduce cutting efficiency and even require shutdown for cleaning. From the perspective of cost control, metal chip splashing also increases the loss of tools and bearings, and increases production costs. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an anti-iron chip splash chuck for bearing cutting, which has the advantage of preventing metal chips from splashing during the cutting process, and solves the problem of metal chips splashing during the bearing cutting process.

[0006] (II) Technical solution

[0007] In order to achieve the purpose of preventing metal chips from splashing during the above-mentioned cutting process, the utility model provides the following technical solutions: a chuck for preventing iron chips from splashing for bearing cutting, comprising a chuck mounted on a machine tool and claws in a circular array on one side of the chuck, and the claws can move toward or away from the axis center, a circular bearing groove is provided at the center of one side of the chuck and on the inner side of the claw, an air duct is provided at the center of the bearing groove, an exhaust component is provided in the air duct, air is sucked in from one side of the claw, a cooling component for reducing the temperature is provided between the inner wall of the air duct and the bearing groove, at least two cooling nozzles are provided on one side of the claw, the cooling nozzle is connected to the machine tool, and coolant or cold air is sprayed into the air duct.

[0008] Preferably, one of the cooling nozzles sprays coolant or water vapor, and the other sprays inert cold air, which can prevent the bearing from heating up and coming into contact with oxygen during the cutting process, leading to oxidation.

[0009] Preferably, the cooling component is specifically a cooling pipe surrounding the air duct, and coolant is passed into the cooling pipe. After cooling the clamped bearing, the coolant is transported to the cooling nozzle through the chuck part and sprayed out as coolant.

[0010] Preferably, an annular baffle ring is provided at the exhaust assembly inside the air duct, and the baffle ring is in contact with the inner wall of the air duct and is movable inside the air duct. When a certain number of pieces are processed, the movable baffle ring can scrape out the coolant and metal chips remaining in the baffle ring, and because there is coolant remaining inside, even if the baffle ring is pulled to scrape out the metal chips, the metal chips will cause less wear on the inner wall of the air duct during the movement.

[0011] Preferably, the cooling component is specifically a refrigeration end, which reduces the ambient temperature through metal contact, and the coolant sprayed from the cooling nozzle is saturated water vapor.

[0012] (III) Beneficial effects

[0013] Compared with the prior art, the utility model provides a chuck for preventing iron chips from splashing for bearing cutting, which has the following beneficial effects:

[0014] 1. The anti-iron chip splash chuck for bearing cutting is used. The worker puts the bearing into the bearing slot and moves the claw to clamp the bearing. During the cutting process, the exhaust component is started to make the air flow move into the air duct and control the power to avoid excessive power causing large metal chips to be sucked into the exhaust component, resulting in equipment damage. At the same time, during the cutting process, the cooling nozzle is turned on to spray mist coolant. After the metal chips come into contact with the coolant, the liquid will adhere to the metal chips, increasing the overall weight, causing the heavier metal chips to fall directly downward under the influence of gravity, and the lighter ones will move into the air duct under the influence of the air flow formed by the exhaust component. At the same time, the coolant that is not attached to the metal chips will also move into the air duct, increasing the amount of liquid attached to the metal chips in the air duct, causing them to fall on the inner wall of the air duct, effectively reducing the splash of metal chips, causing worker injuries or machine wear caused by metal chips. By wrapping the metal chips with liquid and then collecting them, the metal chips are easier to gather. At the same time, there is a lubricating effect of the liquid, which reduces the wear of the metal chips on the equipment.

[0015] 2. The anti-iron chip splash chuck for bearing cutting can move the retaining ring to scrape out the coolant and metal chips remaining in the retaining ring when processing a certain number of pieces. And because there is coolant remaining inside, even if the retaining ring is pulled to scrape out the metal chips, the metal chips will cause less wear on the inner wall of the air duct during the movement. The metal chips can be collected by the retaining ring and processed centrally, which is more portable and increases efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1

[0022] See also Figure 1-2 A chuck for preventing iron chips from splashing for bearing cutting comprises a chuck 1 mounted on a machine tool and claws 11 arranged in a circumferential array on one side of the chuck 1, and the claws 11 can move toward or away from the axis center. A circular bearing groove 12 is provided at the center of one side of the chuck 1 and on the inner side of the claw 11. An air duct 13 is provided at the center of the bearing groove 12. An exhaust component 2 is provided in the air duct 13 to suck air from one side of the claw 11. A cooling component 132 for reducing the temperature is provided between the inner wall of the air duct 13 and the bearing groove 12. At least two cooling nozzles 3 are provided on one side of the claw 11. The cooling nozzles 3 are connected to the machine tool and spray coolant or cold air into the air duct 13. One of the cooling nozzles 3 sprays coolant or water vapor, and the other sprays inert cold air. The inert cold air can prevent the bearing from heating up and coming into contact with oxygen during the cutting process, resulting in oxidation.

[0023] Furthermore, the cooling assembly 132 is specifically a cooling pipe surrounding the air duct 13, and coolant is passed into the cooling pipe. After cooling the clamped bearing, the coolant is partially transported to the cooling nozzle 3 through the chuck 1 and sprayed out as coolant.

[0024] Furthermore, the worker puts the bearing into the bearing slot 12, moves the claw 11 to clamp the bearing, and starts the vacuum assembly 2 during the cutting process to make the air flow move into the air duct 13 and control the power to prevent excessive power from causing larger metal chips to be sucked into the vacuum assembly 2, causing equipment damage. At the same time, during the cutting process, the cooling nozzle 3 is turned on to spray mist coolant. After the metal chips come into contact with the coolant, the liquid will adhere to the metal chips, increasing the overall weight, causing the heavier metal chips to fall directly downward under the influence of gravity, and the lighter ones will be affected by the airflow formed by the vacuum assembly 2 and move into the air duct 13. At the same time, the coolant that is not attached to the metal chips will also move into the air duct 13, increasing the amount of liquid attached to the metal chips in the air duct 13 and causing them to fall on the inner wall of the air duct 13.

[0025] A circular baffle ring 131 is provided at the exhaust component 2 inside the air duct 13. The baffle ring 131 is in contact with the inner wall of the air duct 13 and is movable inside the air duct 13. When a certain number of pieces are processed, the movable baffle ring 131 can scrape out the coolant and metal chips remaining in the baffle ring 131. Because there is coolant remaining inside, even if the baffle ring 131 is pulled to scrape out the metal chips, the metal chips will cause less wear on the inner wall of the air duct 13 during the movement.

[0026] Working principle: The worker puts the bearing into the bearing slot 12, moves the clamping claw 11 to clamp the bearing, and fillets the inner ring of the bearing. During the cutting process, the exhaust component 2 is started to make the air flow move to the air duct 13 and control the power to avoid excessive power causing large metal chips to be sucked into the exhaust component 2, resulting in equipment damage. At the same time, during the cutting process, the cooling nozzle 3 is turned on to spray mist coolant. After the metal chips come into contact with the coolant, the liquid will adhere to the metal chips, increasing the overall weight, so that the heavier metal chips fall directly downward under the influence of gravity, and the lighter ones are affected by the exhaust component. The airflow formed by the metal chips moves into the air duct 13. Meanwhile, the coolant not attached to the metal chips will also move into the air duct 13, so that the amount of liquid attached to the metal chips in the air duct 13 increases, causing the liquid to fall on the inner wall of the air duct 13 and slowly move closer to the retaining ring 131 under the influence of the airflow. When a certain number of pieces are processed, the moving retaining ring 131 can scrape out the coolant and metal chips remaining in the retaining ring 131 together. Moreover, because there is coolant remaining inside, even if the retaining ring 131 is pulled to scrape out the metal chips, the wear of the metal chips on the inner wall of the air duct 13 during the movement is relatively small.

[0027] Embodiment 2

[0028] See also Figure 1 and Figure 3A chuck for preventing iron chips from splashing for bearing cutting comprises a chuck 1 mounted on a machine tool and claws 11 arranged in a circumferential array on one side of the chuck 1, and the claws 11 can move toward or away from the axis center. A circular bearing groove 12 is provided at the center of one side of the chuck 1 and on the inner side of the claw 11. An air duct 13 is provided at the center of the bearing groove 12. An exhaust component 2 is provided in the air duct 13 to suck air from one side of the claw 11. A cooling component 132 for reducing the temperature is provided between the inner wall of the air duct 13 and the bearing groove 12. At least two cooling nozzles 3 are provided on one side of the claw 11. The cooling nozzles 3 are connected to the machine tool and spray coolant or cold air into the air duct 13. One of the cooling nozzles 3 sprays coolant or water vapor, and the other sprays inert cold air. The inert cold air can prevent the bearing from heating up and coming into contact with oxygen during the cutting process, resulting in oxidation.

[0029] Furthermore, the cooling component 132 is specifically a refrigeration end, which reduces the ambient temperature through metal contact, and the coolant sprayed by the cooling nozzle 3 is saturated water vapor, which will liquefy when attached to the metal chips to form water droplets attached to the surface.

[0030] Furthermore, the worker puts the bearing into the bearing groove 12, moves the claw 11 to clamp the bearing, and starts the vacuum assembly 2 during the cutting process to make the air flow move into the air duct 13 and control the power to avoid excessive power causing larger metal chips to be sucked into the vacuum assembly 2, causing equipment damage. At the same time, during the cutting process, the cooling nozzle 3 is turned on to spray saturated water vapor. After the metal chips come into contact with the saturated water vapor, the saturated water vapor will liquefy when it adheres to the metal chips, forming water droplets attached to its surface, increasing the overall weight, so that the heavier metal chips fall directly downward under the influence of gravity, and the lighter ones are affected by the airflow formed by the vacuum assembly 2 and move into the air duct 13. At the same time, the water vapor that is not attached to the metal chips will also move into the air duct 13, so that the liquid attached to the metal chips in the air duct 13 increases, causing them to fall on the inner wall of the air duct 13.

[0031] A circular baffle ring 131 is provided at the exhaust component 2 inside the air duct 13. The baffle ring 131 is in contact with the inner wall of the air duct 13 and is movable inside the air duct 13. When a certain number of pieces are processed, the movable baffle ring 131 can scrape out the coolant and metal chips remaining in the baffle ring 131. Because there is coolant remaining inside, even if the baffle ring 131 is pulled to scrape out the metal chips, the metal chips will cause less wear on the inner wall of the air duct 13 during the movement.

[0032] Working principle: The worker puts the bearing into the bearing slot 12, moves the clamping claw 11 to clamp the bearing, and fillets the inner ring of the bearing. During the cutting process, the exhaust component 2 is started to make the air flow move to the air duct 13 and control the power to avoid excessive power causing large metal chips to be sucked into the exhaust component 2, resulting in equipment damage. At the same time, during the cutting process, the cooling nozzle 3 is turned on to spray saturated water vapor. After the metal chips come into contact with the saturated water vapor, the saturated water vapor will liquefy when attached to the metal chips, forming water droplets attached to its surface, increasing the overall weight, so that the heavier metal chips fall directly downward under the influence of gravity. The lighter ones fall down and are affected by the airflow formed by the exhaust component 2 and move into the air duct 13. At the same time, the water vapor that is not attached to the metal chips will also move into the air duct 13, which increases the liquid attached to the metal chips in the air duct 13, causing them to fall on the inner wall of the air duct 13 and slowly move closer to the retaining ring 131 under the influence of the airflow. When a certain number of pieces are processed, the moving retaining ring 131 can scrape out the coolant and metal chips remaining in the retaining ring 131 together, and because there is coolant remaining inside, even if the retaining ring 131 is pulled to scrape out the metal chips, the metal chips will cause less wear on the inner wall of the air duct 13 during the movement.
