Description

Technical Field

[0001] This invention relates to the field of bearing processing technology, and in particular to a grinding processing apparatus for bearing manufacturing. Background Technology

[0002] A grinding apparatus for bearing manufacturing refers to a device that uses abrasives to precisely machine the surfaces of bearing parts during the bearing production process.

[0003] In the machining process of traditional bearings, the grinding wheel rotates at high speed and squeezes the cutting metal. The friction generates a large amount of grinding heat. If the heat cannot be dissipated quickly, the workpiece is prone to surface annealing, burning, and grinding cracks, which directly reduces the dimensional accuracy and service life of the bearing. Traditional grinding machine cooling nozzles are generally fixed with bolts, and the installation position cannot be adjusted synchronously with the movement of the grinding wheel. When the grinding wheel is inserted into the bearing bore for internal grinding, the grinding wheel head extends into the workpiece cavity, and the distance between the fixed nozzle and the grinding heat generation area increases significantly. It is difficult to accurately spray the grinding fluid to the high-temperature grinding point, and the cooling efficiency drops sharply.

[0004] Furthermore, after prolonged grinding, metal shavings and abrasive particles can easily get stuck inside the grinding wheel's pores. The residual debris can alter the flatness of the grinding wheel's working surface, and subsequent grinding processes can easily produce defects such as scratches and dimensional deviations on the bearing surface.

[0005] Therefore, this application provides a grinding apparatus for bearing manufacturing to meet the requirements. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a grinding processing device for bearing manufacturing, so as to solve the problems that the grinding workpiece is prone to generating a lot of heat during the grinding process, which reduces the grinding accuracy, and the residual debris on the surface of the grinding workpiece will cause a lot of scratches on the surface of the workpiece.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A grinding apparatus for bearing manufacturing includes a grinding machine body. A clamping mechanism is installed on one side of the grinding machine body, and a grinding wheel is disposed on one side of the clamping mechanism. An annular wedge-shaped seat is fixedly connected to the outer wall of the grinding wheel's outer shaft. A driving mechanism is installed at the other end of the grinding wheel and is fixedly connected to the interior of the grinding machine body. An auxiliary cooling component is disposed at the upper end of the grinding wheel to cool the grinding head during the grinding process. A cleaning component is disposed on one side of the auxiliary cooling component to clean debris from the surface of the grinding wheel after grinding. A lifting component is disposed at the other end of the cleaning component on the grinding machine body to drive the cleaning component and the auxiliary cooling component to move up and down. The auxiliary cooling component includes a plurality of first nozzles disposed at the upper end of the grinding wheel. The other ends of the first nozzles are connected to a connecting pipe, and a first electric telescopic rod is fixedly connected to one side of the connecting pipe via an L-shaped rod.

[0008] Optionally, the auxiliary cooling component further includes a first corrugated protective sleeve, which is fitted over the outside of the first electric telescopic rod. A housing is provided on the outside of the first corrugated protective sleeve, and the housing is fixedly connected to the inner wall of the grinding machine body.

[0009] Optionally, the auxiliary cooling component further includes a gear, which is rotatably connected inside the housing. A first rack is meshed with one side of the gear, and a first vertical rod is fixedly connected to one end of the first rack. The bottom end of the first vertical rod passes through the housing and is fixedly connected to a first electric telescopic rod.

[0010] Optionally, the auxiliary cooling component further includes a second rack, which is meshed with the outer wall of the other end of the gear. A second vertical rod is fixedly connected to the top of the second rack, and the top of the second vertical rod passes through the top outer wall of the housing and is slidably connected thereto.

[0011] Optionally, the auxiliary cooling component further includes two second corrugated protective sleeves, which are respectively fitted over the outside of the first vertical rod and the second vertical rod. One end of each of the two second corrugated protective sleeves is fixedly connected to the housing, and the other end of each of the two second corrugated protective sleeves is fixedly connected to the first vertical rod and the second vertical rod, respectively.

[0012] Optionally, the cleaning assembly includes a stepped plate annular seat, which is fixedly connected to one end of the second vertical rod. The stepped plate annular seat is slidably connected to the inner wall of the grinding machine body. The inner wall of the stepped plate annular seat is symmetrically provided with arc-shaped grooves, and each arc-shaped groove is slidably connected to a shaped connecting rod.

[0013] Optionally, the cleaning assembly further includes two arc-shaped rigid tubes, which are rotatably connected to the outer wall of one end of the irregular connecting rod. An arc-shaped corrugated pipe is connected between the two arc-shaped rigid tubes, and several air nozzles are connected inside each of the two arc-shaped rigid tubes.

[0014] Optionally, the cleaning assembly further includes a second electric telescopic rod, which is fixedly connected to the middle of the other end of the stepped plate annular seat, and the output end of the second electric telescopic rod is fixedly connected to a connecting seat.

[0015] Optionally, the cleaning assembly further includes two connecting rods, each of which is rotatably connected to the other end of the irregular connecting rod, and the other end of each of the two connecting rods is rotatably connected to the connecting seat.

[0016] Optionally, the lifting assembly includes a spherical slide rod, which is fixedly connected to the outer wall of the other end of the stepped plate annular seat. The outer wall of the spherical slide rod is in contact with the inclined surface of the annular wedge seat. A spring is sleeved on the outer wall of the bottom end of the spherical slide rod. One end of the spring is fixedly connected to the spherical slide rod. Two sliding sleeves are slidably connected to the outer wall of the top end of the spherical slide rod. The top end of the spring is fixedly connected to the sliding sleeves. The other ends of the two sliding sleeves are fixedly connected to the inner wall of the grinding machine body.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, a mechanical linkage transmission structure is formed by an annular wedge seat at the grinding wheel shaft end, a spherical slide bar, a spring, and a gear rack. When the grinding wheel extends into the bearing inner hole for grinding, the cooling nozzle automatically follows and sinks to near the high-temperature grinding surface. The grinding fluid is precisely sprayed from the first nozzle through the connecting pipe onto the friction-heated position. This improves the shortcomings of traditional fixed nozzles that are too far from the grinding area, have coolant deviation, and insufficient cooling. It effectively prevents defects such as high-temperature burns, surface annealing, and grinding cracks in the bearing workpiece. Based on the linkage lifting of the nozzle, the first electric telescopic rod can laterally pull the connecting pipe and the first nozzle to move back and forth. The spray point can be flexibly adjusted according to the bearings with different inner and outer diameters, adapting to the production of multiple models. At the same time, the first electric telescopic rod is equipped with a first corrugated protective sleeve on the outside, and the first and second vertical rods are equipped with second corrugated protective sleeves. This can prevent splashed grinding fluid and fine metal chips from entering the gear rack transmission space inside the housing, avoid corrosion and jamming of transmission parts, extend the service life of the cooling mechanism, and reduce the frequency of equipment downtime for maintenance.

[0018] The purging structure, consisting of a second electric telescopic rod, connecting rods, irregularly shaped connecting rods, arc-shaped grooves, arc-shaped rigid tubes, and arc-shaped corrugated pipes, utilizes a combination of these components. The second electric telescopic rod extends and retracts, raising and lowering the connecting seat. Two connecting rods simultaneously pull the irregularly shaped connecting rods on both sides, causing them to slide along the arc-shaped grooves on the inner wall of the stepped annular seat. These connecting rods then drive the arc-shaped rigid tubes and air nozzles to reciprocate along the arc-shaped trajectory of the grinding wheel. High-pressure gas is evenly distributed to the arc-shaped rigid tubes on both sides through the arc-shaped corrugated pipes, and then ejected by multiple sets of air nozzles. The purging trajectory completely covers the entire outer circumference of the grinding wheel. (Comparison with fixed-point solidification...) The fixed air-blowing structure can thoroughly clean the metal debris and detached abrasive particles embedded in the grinding wheel pores. The irregular connecting rod adopts a hinged Z-shaped split structure. When moving along the arc groove curve, the hinge point adapts to the angle change, overcoming the defect of traditional rigid connecting rods that are prone to twisting and jamming during arc movement. The swinging motion is smooth and stable in the machining environment with accumulated grinding debris and high moisture content, avoiding residue residue that causes unevenness on the working surface of the grinding wheel. It eliminates bearing scratches and dimensional deviations in subsequent machining from the source, extends the service life of the grinding wheel, and continuously ensures the accuracy of bearing grinding.

[0019] By sharing a single gear rack and wedge seat lifting transmission system, the cleaning and cooling components achieve synchronous lifting and linkage between the two mechanisms. During grinding, the stepped plate annular seat, along with the entire air-blowing cleaning component, is lifted synchronously, keeping the air nozzles away from the grinding wheel and preventing interference with normal grinding operations. After the grinding wheel finishes machining and retracts, the annular wedge seat releases pressure on the spherical slide bar, and the spring rebounds, causing the entire cleaning component to automatically fall to the cleaning station around the grinding wheel, effectively reducing the production cost of the device.

Detailed Implementation

[0022] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0023] like Figures 1 to 8 As shown, an embodiment of the present invention provides a grinding apparatus for bearing manufacturing, including a grinding machine body 1. A clamping mechanism 2 is installed on one side of the interior of the grinding machine body 1 for clamping materials. A grinding wheel 3 is arranged on one side of the clamping mechanism 2. An annular wedge seat 8 is fixedly connected to the outer wall of the shaft of the grinding wheel 3. A driving mechanism 4 is installed on the other end of the grinding wheel 3 and is fixedly connected to the interior of the grinding machine body 1. An auxiliary cooling component 5 is arranged on the upper end of the grinding wheel 3 for cooling the grinding head during the grinding process. A cleaning component 6 is arranged on one side of the auxiliary cooling component 5 for cleaning the grinding head during the grinding process. To clean the debris on the surface of the grinding wheel 3 after grinding, a lifting component 7 is provided at the other end of the cleaning component 6 of the grinding machine body 1. The lifting component 7 is used to drive the cleaning component 6 and the auxiliary cooling component 5 to move up and down. The auxiliary cooling component 5 includes a number of first nozzles 501. The number of first nozzles 501 are arranged at the upper end of the grinding wheel 3. The pipes of the connecting part of the first nozzles 501 are flexible pipes with adjustable shape, which makes it easy to adjust the angle of the nozzles according to the cooling position. The other end of the number of first nozzles 501 is connected to a connecting pipe 502. One side of the connecting pipe 502 is fixedly connected to a first electric telescopic rod 503 by an L-shaped rod.

[0024] like Figures 2 to 5As shown, the auxiliary cooling component 5 also includes a first corrugated protective sleeve 504, which is fitted over the outside of the first electric telescopic rod 503. The first corrugated protective sleeve 504 protects the first electric telescopic rod 503 without affecting its operation, and prevents the first electric telescopic rod 503 from being damaged by debris. A housing 509 is provided on the outside of the first corrugated protective sleeve 504, and the housing 509 is fixedly connected to the inner wall of the grinding machine body 1. The auxiliary cooling component 5 also includes a gear 508, which is rotatably connected inside the housing 509. A first rack 505 is meshed with one side of the gear 508, and a first vertical rod is fixedly connected to one end of the first rack 505. The bottom end of the first vertical rod passes through the housing 509 and is fixedly connected to the first electric telescopic rod 503. The auxiliary cooling component 5 also includes a second rack 506, which is meshed with the other side of the gear 508. The outer walls of the first rack 505 and the second rack 506 are slidably connected to slide rails. Each slide rail is fixedly connected to the inner wall of the housing 509. The top of the second rack 506 is fixedly connected to a second vertical rod. The top of the second vertical rod passes through the top outer wall of the housing 509 and is slidably connected to it. The auxiliary cooling component 5 also includes two second corrugated protective sleeves 507. The second corrugated protective sleeves 507 are corrugated pipes with an elastic structure, which can deform during the movement of the first rack 505 and the second rack 506, thereby preventing debris from entering the interior of the housing 509 and affecting the operation of the first rack 505, the second rack 506 and the gear 508. The two second corrugated protective sleeves 507 are respectively fitted on the outside of the first vertical rod and the second vertical rod. One end of each of the two second corrugated protective sleeves 507 is fixedly connected to the housing 509, and the other end of each of the two second corrugated protective sleeves 507 is fixedly connected to the first vertical rod and the second vertical rod, respectively.

[0025] like Figures 1 to 8As shown, the cleaning component 6 includes a stepped plate annular seat 605, which is fixedly connected to one end of the second vertical rod. The stepped plate annular seat 605 is slidably connected to the inner wall of the grinding machine body 1. The stepped plate annular seat 605 is formed by two semicircular plates of different heights fixed to each other. Arc grooves 606 are provided on the inner walls of both sides of the two semicircular plates. An air nozzle 601 is provided on the side of the slightly lower semicircular plate, and a connecting rod 607 and a second electric telescopic rod 608 are provided on the side of the slightly higher semicircular plate to prevent the movement trajectory of the output end of the second electric telescopic rod 608 from interfering with the location of the grinding wheel 3. The rod body interferes with the inner wall of the stepped plate annular seat 605, which has symmetrical arc-shaped grooves 606. Each arc-shaped groove 606 has a slidably connected irregular connecting rod 604 on its inner wall. The irregular connecting rod 604 consists of a Z-shaped rod and two rotating shafts. The two ends of the Z-shaped rod are respectively hinged to the two rotating shafts, and the other ends of the two rotating shafts are respectively rotatably connected to the arc-shaped rigid tube 602 and the other end of the connecting rod 607. When the second electric telescopic rod 608 pushes the irregular connecting rod 604 to slide along the arc-shaped groove 606 through the connecting rod 607, the hinge structure between the Z-shaped rod and the rotating shaft allows each component to change according to the arc trajectory. The structure adaptively adjusts the relative angle, thus avoiding the problems of rigid torsion, jamming, or even damage caused by the inability to rotate in traditional rigid rods during arc-shaped movements. This concentrates the bending deformation during movement at the hinge point, rather than the rod itself, reducing the risk of fatigue fracture. The cleaning component 6 also includes two arc-shaped rigid tubes 602, each rotatably connected to the outer wall of one end of the irregular connecting rod 604. An arc-shaped corrugated pipe 603 connects the two arc-shaped rigid tubes 602, and several air nozzles 601 are connected inside each of the two arc-shaped rigid tubes 602. The connecting pipe is a deformable pipe, which facilitates the adjustment of the pipe shape according to the nozzle direction of the air nozzle 601, thereby improving the cleaning efficiency of the air nozzle 601. The cleaning assembly 6 also includes a second electric telescopic rod 608, which is fixedly connected to the middle of the other end of the stepped plate annular seat 605. The output end of the second electric telescopic rod 608 is fixedly connected to a connecting seat 609. The cleaning assembly 6 also includes two connecting rods 607, which are rotatably connected to the other end of the irregular connecting rod 604, and the other end of both connecting rods 607 is rotatably connected to the connecting seat 609.

[0026] like Figures 1 to 6As shown, the lifting assembly 7 includes a spherical slide rod 701, which consists of a sphere and a vertical slide rod. A spring 703 is sleeved on the outside of the vertical slide rod, and a sliding sleeve 702 is slidably connected to the outer wall of the top of the vertical slide rod. The surface of the sphere is in contact with the inclined surface of the annular wedge seat 8, which facilitates the inclined surface of the annular wedge seat 8 to apply pressure to the slide rod. The spherical slide rod 701 is fixedly connected to the outer wall of the other end of the stepped plate annular seat 605. The outer wall of the spherical slide rod 701 is in contact with the inclined surface of the annular wedge seat 8. A spring 703 is fitted on the bottom outer wall of the grinding machine body 1. One end of the spring 703 is fixedly connected to the spherical slide rod 701. Two sliding sleeves 702 are slidably connected to the top outer wall of the spherical slide rod 701. The sliding sleeves 702 facilitate the limiting and guiding of the spherical slide rod 701, so that the spherical slide rod 701 can move according to the predetermined track and avoid the spherical slide rod 701 from deflecting during the movement. The top of the spring 703 is fixedly connected to the sliding sleeve 702, and the other end of the two sliding sleeves 702 is fixedly connected to the inner wall of the grinding machine body 1.

[0027] The working principle of the technical solution provided by this invention is as follows: During operation, the material is placed on the clamping mechanism 2, and the clamping mechanism 2 is activated to clamp the material. Then, the drive mechanism 4 is activated, which drives the grinding wheel 3 to move towards the material. The grinding wheel 3 drives the annular wedge seat 8 to move in the same direction. The inclined surface of the annular wedge seat 8 applies pressure to the spherical slide rod 701, causing the spherical slide rod 701 to move upward. At the same time, the spring 703 is compressed. Simultaneously, the spherical slide rod 701 drives the stepped plate annular seat 605 to move upward. The stepped plate annular seat 605 drives the air nozzle 601 to move in the same direction. At the same time, the stepped plate annular seat 605 drives the second vertical rod to move upward. The second vertical rod drives the second rack 506 to move in the same direction. The second rack 506 drives the gear 508 to rotate. The gear 508 drives the first rack 505 to move downward. 5. The first vertical rod moves downward, which in turn moves the first electric telescopic rod 503 downward. The first electric telescopic rod 503 moves the L-shaped rod downward, which in turn moves the first nozzle 501 downward. When the grinding wheel 3 moves to the inside of the material, the first nozzle 501 descends to a height close to the grinding wheel 3. At this time, the first electric telescopic rod 503 is activated, and its output end moves the L-shaped rod towards the material. The L-shaped rod moves the first nozzle 501 to the position of the grinding wheel 3. The grinding wheel 3 is then activated to grind the material. Simultaneously, the connecting pipe 502 is connected to the high-pressure liquid pipeline, allowing the high-pressure liquid to enter the first nozzle 501 through the connecting pipe 502 and then be sprayed out through the first nozzle 501. The high-pressure liquid cools the grinding wheel 3 during the grinding process.

[0028] Furthermore, after grinding is completed, the drive mechanism 4 is restarted. The drive mechanism 4 drives the grinding wheel 3 away from the material, and the grinding wheel 3 drives the annular wedge seat 8 to move in the same direction. At the same time, the pressure applied by the inclined surface of the annular wedge seat 8 to the ball at the bottom of the spherical slide rod 701 gradually decreases. The spherical slide rod 701 gradually moves down under the action of the spring 703. The spherical slide rod 701 drives the stepped plate annular seat 605 to move down. At the same time, the stepped plate annular seat 605 drives the air nozzle 601 to move down. At the same time, the stepped plate annular seat 605 drives the second vertical rod to move in the same direction. The second vertical rod drives the second rack 506 to move in the same direction. The second rack 506 drives the gear 508 to rotate in the opposite direction. The gear 508 drives the first rack 505 to move up. The first rack 505 drives the first vertical rod to move up. The first vertical rod drives the L-shaped rod to move up. The connecting pipe 502 drives the first nozzle 501 to reset.

[0029] Furthermore, after the drive mechanism 4 drives the grinding wheel 3 to reset, the air nozzle 601 moves downward to the vicinity of the grinding wheel 3. At this time, the arc-shaped bellows 603 is connected to the high-pressure air pipe, allowing high-pressure gas to enter the arc-shaped bellows 603. The high-pressure gas is then introduced into the arc-shaped rigid pipe 602 through the arc-shaped bellows 603, and then into the air nozzle 601 through the arc-shaped rigid pipe 602. The air nozzle 601 then cleans impurities on one side of the surface of the grinding wheel 3. Finally, the second electric telescopic rod 608 is activated, and the second electric telescopic rod... The output end of 608 drives one end of the connecting rod 607 to move upward, and then applies pressure to the other end of the connecting rod 607. Then, the other end of the connecting rod 607 applies pressure to the irregular connecting rod 604, causing the irregular connecting rod 604 to slide upward along the arc track of the arc groove 606. At the same time, the irregular connecting rod 604 drives the arc rigid tube 602 to move in the same direction, and the arc rigid tube 602 drives the air nozzle 601 to move in the same direction. Then, the air nozzle 601 cleans other parts of the surface of the grinding wheel 3 along the arc track.
