Description

Technical Field

[0001] The invention belongs to the technical field of bearing processing, in particular to a multi-surface superfinishing grinding device for processing a bearing ring. Background Art

[0002] The bearing super finishing process is a finishing method that uses a feed motion to achieve micro-grinding. The surface before super finishing is generally precision turned and ground. Specifically, it refers to a finishing method that uses a fine-grained grinding tool to apply very little pressure to the bearing under good lubrication and cooling conditions, and performs fast and short reciprocating oscillation motion on the bearing rotating at a certain speed in a direction perpendicular to the bearing's rotation direction.

[0003] At present, there is a gradual demand for super-finishing of the raceways and rib surfaces of large domestic wind turbine bearing rings. The life of the bearings after super-finishing is longer, but the existing large-scale super-finishing machines on the market have simple functions and cannot meet the requirements of processing multiple surfaces such as straight raceways, inclined raceways, arc raceways, ribs and flat raceways on the same machine tool. Therefore, it is necessary to design a multi-surface super-finishing device. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention solves the technical problems by adopting a technical solution: a multi-surface superfinishing grinding device for bearing ring processing, comprising a supporting base plate, a rotating shaft device is arranged on the upper surface of the supporting base plate, a grinding bearing ring is arranged inside the rotating shaft device, and a grinding component is arranged on the back of the supporting base plate; The rotating shaft device comprises an axial motor, the outer surface of the output shaft of the axial motor is fixedly connected with a connecting sleeve, and the outer surface of the axial motor is provided with a modified chassis; the modified chassis comprises an adsorption disk shell, the upper part of the inner cavity of the adsorption disk shell is evenly provided with adsorption mesh holes, and the adsorption disk shell can adsorb and remove impurities from the bearing ring during the grinding process through the adsorption mesh holes, and the upper surface of the adsorption disk shell is symmetrically provided with horizontal guide grooves, and the interior of the horizontal guide grooves is slidably connected with a matching clamping plate; The grinding component includes a height-adjusting base, the top of the inner wall of the height-adjusting base is slidably connected to a vertical baffle, the back of the outer surface of the vertical baffle is fixedly connected to a propulsion back box, the front of the propulsion back box is fixedly connected to a sliding inner rod through a segmented push rod, the bottom of the sliding inner rod is fixedly connected to an inverted motor, and the outer surface of the output shaft of the inverted motor is fixedly connected to an eccentric oilstone sleeve. Although it is sleeved on the output shaft of the inverted motor, the axis line of the inverted motor is adjacent to the axis line of the eccentric oilstone sleeve and maintains a certain distance. Therefore, when the inverted motor controls the rotation of the eccentric oilstone sleeve, the actual rotation range of the eccentric oilstone sleeve will become larger.

[0005] Furthermore, a pressure-sensitive inner box is fixedly connected to the bottom of the vertical baffle inner cavity, a force-bearing push rod is slidably connected to the middle of the front side of the pressure-sensitive inner box, a rotating shaft roller is rotatably connected to the top of the force-bearing push rod, an extended outer shell is fixedly connected to the middle of the vertical baffle inner cavity, and a pre-pressure component is provided at the front end of the extended outer shell inner cavity.

[0006] Furthermore, the bottom of the height adjustment base is fixedly connected to the back of the upper surface of the support base plate, the outer surface of the sliding inner rod is slidably connected to the inner wall of the extension shell through a guide groove, the outer surface of the eccentric oilstone sleeve extends to the outside of the extension shell, and the outer surface of the force-bearing push rod is slidably connected to the inner cavity of the vertical baffle through a through hole. The bottom end of the grinding bearing ring is slidably connected to the upper surface of the adsorption disk shell, the number of the matching clamping plates is two groups, and the inner wall of the matching clamping plate is evenly provided with transfer rollers on one side close to the bottom of the grinding bearing ring, and the outer surface of the transfer roller is rotatably connected to the inner wall of the matching clamping plate through a rotation groove.

[0007] Furthermore, a receiving sliding shell is symmetrically fixed on both sides of the outer surface of the connecting sleeve, a propulsion slide is slidably connected to the inner wall of the receiving sliding shell, and internal pressure slides are symmetrically arranged on both sides of the inner cavity of the propulsion slide, and the surface of the internal pressure slide in contact with the polished bearing ring is an arc structure, so as to fit the inner wall of the polished bearing ring to the maximum extent and increase the friction with the polished bearing ring, and the side of the outer surface of the internal pressure slide away from the inner wall of the polished bearing ring is slidably connected to the wall-attached receiving shell, and the side of the inner wall of the wall-attached receiving shell close to the receiving sliding shell is fixedly connected to a pressure-sensitive plate. The pressure-bearing surface of the pressure-sensitive plate is fixedly connected to the outer surface of the internal pressure slide through an elastic pressure rod, and the side of the outer surface of the internal pressure slide away from the elastic pressure rod is pressed against the inner wall of the polished bearing ring, and the number of the receiving sliding shells is two, and the number of the internal pressure slides is four.

[0008] Furthermore, the pre-stressing component includes a curved slider, metal connecting rods are symmetrically arranged on both sides of the curved slider, one end of the metal connecting rod away from the curved slider is fixedly connected to a vertical connecting plate, the outer surface of the vertical connecting plate is slidably connected to a fixed bar shell, the bottom of the inner wall of the fixed bar shell is fixedly connected to a downward pressure element, and the upper surface of the downward pressure element is fixedly connected to a compression connecting tube.

[0009] Furthermore, the number of the fixed bar shells is two, the outer surface of the vertical connecting plate is slidably connected to the inner wall of the fixed bar shell near the curved slider through a vertical sliding groove, the top of the vertical connecting plate is fixedly connected to the top of the compression tube, the bottom end of the pressing element is extended to the outside of the fixed bar shell through an external wire, and the pressing element transmits the pressure of the compression tube to the pressure measuring computer outside the device through the wire at the bottom, so as to adjust the distance between the extended shell and the grinding bearing ring. The outer surface of the fixed bar shell is fixedly connected to the inner cavity of the extended shell, the outer surface of the curved slider is slidably connected to the inner wall of the extended shell, and the bottom end of the curved slider extends to the outside of the extended shell, and the bottom of the curved slider and the top of the grinding bearing ring are pressed against each other.

[0010] The beneficial effects of the present invention are as follows: 1. The device can perform relatively precise grinding work on the bearing ring placed on the rotating shaft equipment through the grinding component, so that the outer surface of the bearing ring becomes smoother. Since the adsorption disk shell at the bottom can limit the bearing rings of different sizes through the matching clamps on both sides, and the grinding component can also be adjusted according to the actual situation, the device can be applied to the grinding work of bearing rings of more different sizes, meet various processing needs, and improve the general performance of the device.

[0011] 2. The oilstone sleeve of the device does not rotate stably around the inverted motor, but the eccentric sleeve rotates eccentrically on the rotating shaft of the inverted motor, so that the outer surface of the polished bearing ring is cleaned through the high-frequency vibration of the oilstone sleeve and the contact with the outer surface of the polished bearing ring. During the high-frequency oscillation, the residue is not easy to adhere to the outer surface of the bearing ring, and the adsorption disk shell at the bottom can clean up the detached impurities in time, so there will be no problem of impurities flying and causing a dirty and messy processing environment.

[0012] 3. When the device applies appropriate extrusion force to the inner wall of the eccentric sleeve by adjusting the propulsion slide, in order to avoid excessive pressure on the inner wall of the eccentric sleeve, which may cause deformation and damage to the inner wall of the eccentric sleeve, when the propulsion slide is about to contact the inner wall of the eccentric sleeve, the internal pressure slide is first used for buffering and pre-pressing to slow down the propulsion speed of the accommodating slide shell, so that the propulsion slide stops moving in time to avoid excessive propulsion.

[0013] 4. When the extended housing descends, the curved slider at the bottom contacts the top of the grinding bearing ring first, and the actual advancement distance of the eccentric oilstone sleeve on the grinding bearing ring is fed back through the wire, thereby ensuring that the advancement distance of the eccentric oilstone sleeve is controllable and limiting the actual sliding distance of the eccentric oilstone sleeve, preventing the eccentric oilstone sleeve from contacting the adsorption disk shell below, causing the adsorption disk shell to wear.

[0016] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0017] Example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: a multi-surface superfinishing grinding device for bearing ring processing, comprising a supporting base plate 1, a rotating shaft device 2 is arranged on the upper surface of the supporting base plate 1, a grinding bearing ring 4 is arranged inside the rotating shaft device 2, and a grinding component 3 is arranged on the back of the supporting base plate 1; The rotating shaft device 2 includes an axis motor 21, the outer surface of the output shaft of the axis motor 21 is fixedly connected with a connecting sleeve 22, and the outer surface of the axis motor 21 is provided with a modified chassis 5; the modified chassis 5 includes an adsorption disk shell 51, and the upper part of the inner cavity of the adsorption disk shell 51 is evenly provided with adsorption mesh holes 52, and the adsorption disk shell 51 can adsorb and remove impurities from the bearing ring during the grinding process through the adsorption mesh holes 52, and the upper surface of the adsorption disk shell 51 is symmetrically provided with horizontal guide grooves 53, and the interior of the horizontal guide grooves 53 is slidably connected with a matching clamping plate 54; The grinding component 3 includes a height-adjusting base 31, the top of the inner wall of the height-adjusting base 31 is slidably connected to a vertical baffle 32, the back of the outer surface of the vertical baffle 32 is fixedly connected to a propulsion back box 33, the front of the propulsion back box 33 is fixedly connected to a sliding inner rod 34 through a segmented push rod, the bottom of the sliding inner rod 34 is fixedly connected to an inverted motor 35, and the outer surface of the output shaft of the inverted motor 35 is fixedly connected to an eccentric oilstone sleeve 36. Although it is sleeved on the output shaft of the inverted motor 35, the axis line of the inverted motor 35 is adjacent to the axis line of the eccentric oilstone sleeve 36 and maintains a certain distance, so when the inverted motor 35 controls the rotation of the eccentric oilstone sleeve 36, the actual rotation range of the eccentric oilstone sleeve 36 will become larger.

[0018] A pressure-sensitive inner box 37 is fixedly connected to the bottom of the inner cavity of the vertical baffle 32, a force-bearing push rod 38 is slidably connected to the middle of the front side of the pressure-sensitive inner box 37, a rotating shaft roller 39 is rotatably connected to the top of the force-bearing push rod 38, an extended shell 310 is fixedly connected to the middle of the inner cavity of the vertical baffle 32, and a pre-pressure component 6 is provided at the front end of the inner cavity of the extended shell 310.

[0019] The bottom of the height adjustment base 31 is fixedly connected to the back of the upper surface of the support base plate 1, the outer surface of the sliding inner rod 34 is slidably connected to the inner wall of the extended shell 310 through the guide groove, the outer surface of the eccentric oilstone sleeve 36 extends to the outside of the extended shell 310, and the outer surface of the force push rod 38 is slidably connected to the inner cavity of the vertical baffle 32 through the through hole. The bottom end of the grinding bearing ring 4 is slidably connected to the upper surface of the adsorption disk shell 51, and the number of the matching clamping plates 54 is two groups. The inner wall of the matching clamping plates 54 is evenly provided with transfer rollers 55 on one side close to the bottom of the grinding bearing ring 4, and the outer surface of the transfer rollers 55 is rotatably connected to the inner wall of the matching clamping plates 54 through the rotation groove.

[0020] Before using the device to perform fine grinding on the polished bearing ring 4, first pull apart the mating clamps 54 on both sides of the adsorption disk shell 51, then insert the bottom of the polished bearing ring 4 into the gap between the mating clamps 54, and then loosen the mating clamps 54. The mating clamps 54 of the same group are pulled together along the horizontal guide groove 53 by the traction of the bottom spring, and are clamped to the bottom of the polished bearing ring 4 through the transfer roller 55 on the inner wall.

[0021] The connecting sleeve 22 on the output shaft of the axial motor 21 is provided with corresponding adapter devices on both sides, which can push the inner wall of the grinding bearing ring 4 outward, thereby clamping the grinding bearing ring 4, and then twisting the grinding bearing ring 4 to cooperate with the work of the grinding component 3 to grind the outer surface of the rotating grinding bearing ring 4.

[0022] When the bearing ring rotates, the height-adjusting base 31 located on the back pulls down the vertical baffle 32. At this time, the extended shell 310 drives the sliding inner rod 34 and the eccentric oilstone sleeve 36 on the front side to descend, and then the back box 33 is pushed through the segmented rod to push the sliding inner rod 34 to the side close to the outer surface of the polished bearing ring 4, so that the eccentric oilstone sleeve 36 controlled to rotate by the inverted motor 35 can contact the polished bearing ring 4, thereby fully polishing the outer surface of the polished bearing ring 4.

[0023] When the eccentric oilstone sleeve 36 rotates, since the actual rotation range of the eccentric oilstone sleeve 36 is larger than itself, the eccentric oilstone sleeve 36 is not always in contact with the polished bearing ring 4, but indirectly rubs the outer surface of the bearing ring 4 with high frequency. Therefore, in order to obtain the actual rotation range of the eccentric oilstone sleeve 36, after the sliding inner rod 34 stops moving, the rotating shaft roller 39 that is always in contact with the eccentric oilstone sleeve 36 will squeeze the pressure-sensitive inner box 37 under the rotation thrust of the eccentric oilstone sleeve 36, thereby obtaining the actual rotation range of the eccentric oilstone sleeve 36, avoiding the problem that the eccentric oilstone sleeve 36 is too close to the polished bearing ring 4, resulting in excessive wear of the polished bearing ring 4.

[0024] The particle impurities that fall off from the outer surface of the bearing ring during grinding will be adsorbed by the adsorption mesh 52 on the upper surface of the adsorption disk shell 51, thereby achieving the impurity removal work, and when the polished bearing ring 4 rotates, it will roll relative to the inner wall of the matching clamping plate 54 through the transfer roller 55, thereby effectively reducing the friction resistance of the polished bearing ring 4, so that the polished bearing ring 4 can rotate more smoothly.

[0025] Example 2, please refer to Figure 1-Figure 7The present invention provides a technical solution: on the basis of the first embodiment, a receiving sliding shell 23 is symmetrically fixed on both sides of the outer surface of the connecting rotating sleeve 22, a pushing slide plate 24 is slidably connected to the inner wall of the receiving sliding shell 23, and an internal pressure slide plate 25 is symmetrically arranged on both sides of the inner cavity of the pushing slide plate 24. The surface of the internal pressure slide plate 25 in contact with the polished bearing ring 4 is an arc surface structure, so as to fit the inner wall of the polished bearing ring 4 to the maximum extent and increase the friction with the polished bearing ring 4. The side of the outer surface of the internal pressure slide plate 25 away from the inner wall of the polished bearing ring 4 is slidably connected to the wall-attached receiving shell 28, and the side of the inner wall of the wall-attached receiving shell 28 close to the receiving sliding shell 23 is fixedly connected to the pressure-sensitive plate 27. The pressure-bearing surface of the pressure-sensitive plate 27 is fixedly connected to the outer surface of the internal pressure slide plate 25 through an elastic pressure rod 26, and the side of the outer surface of the internal pressure slide plate 25 away from the elastic pressure rod 26 is pressed against the inner wall of the polished bearing ring 4. There are two receiving sliding shells 23 and four internal pressure slide plates 25.

[0026] The pre-stressing component 6 includes a curved slider 61, and metal connecting rods 62 are symmetrically arranged on both sides of the curved slider 61. The end of the metal connecting rod 62 away from the curved slider 61 is fixedly connected to a vertical connecting plate 63, and the outer surface of the vertical connecting plate 63 is slidably connected to a fixed bar shell 64. The bottom of the inner wall of the fixed bar shell 64 is fixedly connected to a downward pressing element 66, and the upper surface of the downward pressing element 66 is fixedly connected to a compression connecting tube 65.

[0027] There are two fixed bar shells 64. The outer surface of the vertical connecting plate 63 is slidably connected to the inner wall of the fixed bar shell 64 near the curved slider 61 through a vertical slide groove. The top of the vertical connecting plate 63 is fixedly connected to the top of the compression sleeve 65. The bottom end of the pressing element 66 extends to the outside of the fixed bar shell 64 through an external wire. The pressing element 66 transmits the pressure of the compression sleeve 65 to the pressure measuring computer outside the device through the wire at the bottom, so as to adjust the distance between the extended housing 310 and the grinding bearing ring 4. The outer surface of the fixed bar shell 64 is fixedly connected to the inner cavity of the extended housing 310. The outer surface of the curved slider 61 is slidably connected to the inner wall of the extended housing 310, and the bottom end of the curved slider 61 extends to the outside of the extended housing 310. The bottom of the curved slider 61 and the top of the grinding bearing ring 4 are pressed against each other.

[0028] The accommodating sliding shells 23 on both sides can adjust the squeezing pressure between the outer surface of the propulsion slide 24 and the polished bearing ring 4 by pushing the propulsion slide 24 outward, thereby driving the polished bearing ring 4 to rotate. When the propulsion slide 24 is about to contact the inner wall of the polished bearing ring 4, the internal pressure slides 25 on both sides first squeeze the inner wall of the polished bearing ring 4, and then shrink to the inside of the wall-attached accommodating shell 28, and trigger the pressure-sensitive plate 27 through the elastic pressure rod 26, so that the speed of the propulsion slide 24 controlled by the accommodating sliding shell 23 is reduced, thereby making the squeezing pressure between the propulsion slide 24 and the polished bearing ring 4 moderate.

[0029] When the extended shell 310 descends, the bent slider 61 located below first contacts the top of the grinding bearing ring 4, and then the bent slider 61 slides up with the extrusion force, driving the compression sleeve 65 to lengthen through the vertical connecting plate 63. At this time, the downward pressure element 66 will reduce the pressure of the compression sleeve 65, and the actual advancement distance of the eccentric oilstone sleeve 36 on the grinding bearing ring 4 will be fed back through the wire, thereby ensuring that the advancement distance of the eccentric oilstone sleeve 36 is controllable.

[0030] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
