Description

Technical Field

[0001] The present invention belongs to the technical field of bearing processing equipment, and particularly relates to a bearing ring processing equipment. Background Art

[0002] A bearing is a component used to support the rotation of mechanical parts or mechanical mechanisms in mechanical equipment. Its function is to reduce the friction during movement. With the increasingly rapid update and iteration of modern mechanical equipment, the requirement for the precision of bearings is also getting higher and higher. A bearing includes two annular bearing rings, and several rolling elements are provided between the two bearing rings. The two bearing rings rotate relative to each other through the rolling elements. After the bearing rings and the rolling elements are assembled, in order to protect the rolling elements, prevent dust and other sundries from entering between the two bearing rings, extend the service life of the bearing, and at the same time avoid the leakage of lubricating oil, a sealing ring is generally installed between the bearing rings.

[0003] When the existing processing and assembly equipment for bearing rings and sealing rings is in use, generally only the sealing ring can be installed on one side of the bearing ring, and then the installation on the other side is carried out. The alternate installation requires multiple positioning of the bearing ring and the sealing ring. Not only is the efficiency low, but also the positioning accuracy of the pressing component for the bearing ring and the sealing ring is not high, and misalignment is likely to occur. This not only causes waste of raw materials, but also requires rework, which seriously delays the processing progress. Summary of the Invention

[0050] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0051] like Figure 1-12 As shown, a bearing ring processing equipment includes a body frame for supporting, a pressing assembly 1 installed on the body frame, a sealing ring blanking assembly 2 arranged on the left and right sides of the pressing assembly 1, a bearing ring blanking assembly 3 arranged on the back of the pressing assembly 1, a sealing ring picking assembly 4 arranged on the front of the pressing assembly 1 and a bearing ring picking assembly 5 arranged between the pressing assembly 1 and the bearing ring blanking assembly 3.

[0052] Refer to the attached Figure 4-6 The pressing assembly 1 includes a lower pressing head 11 and an upper pressing head 12 used in conjunction with each other. At the same time, a sliding support 14 is fixedly installed between the body frame supports. The two ends of the sliding support 14 are fixed by a supporting plate. The lower pressing head 11 is fixed to the supporting plate at its bottom, and a pressing hydraulic cylinder 15 is fixedly installed on the top supporting plate. The upper pressing head 12 is fixedly connected to the power output end of the pressing hydraulic cylinder 15. A sliding support plate 13 is also slidably installed between the sliding supports 14. The top of the upper pressing head 12 is installed on the sliding support plate 13. A limiting support 16 is arranged directly below the diagonal of the sliding support plate 13, so that the pressing hydraulic cylinder 15 is used to push the upper pressing head 12 to move downward along the sliding support 14. At the same time, the setting of the sliding support plate 13 ensures the stability of the downward movement, and in conjunction with the limiting support 16, when the upper pressing head 12 moves down to the limit position, the downward position can be limited by resisting the sliding support plate 13, thereby ensuring the safety of equipment processing.

[0053] Refer to the attached Figure 6-8, Further, to ensure accurate positioning of the bearing ring and the sealing ring, the lower pressing head 11 includes a lower support 111 fixedly installed on the support, and a lower positioning pin column 113 vertically slidably installed inside the lower support 111. A lower top plate 112 is arranged around the periphery of the lower positioning pin column 113 on the top surface of the lower support 111. A first limiting spring 116 is installed between the bottom surface of the lower positioning pin column 113 and the chute of the lower support 111. The diameter of the top end of the lower positioning pin column 113 is the same as the inner diameter of the bearing ring, and the diameter of the bottom end of the lower positioning pin column 113 is the same as the diameter of the sealing ring. A buffer slope 114 is arranged at the diameter transition. In this way, when the lower sealing ring is placed on the top end of the lower positioning pin column 113, it can slide down along its top end, and at the same time, a downward force is applied to the lower sealing ring, so that it can be sleeved on the large-diameter part at the bottom end of the lower positioning pin column 113. At the same time, it is placed on the lower top plate 112 to complete the positioning. At the same time, when the bearing is placed, it can use its own gravity and the downward force applied to make it sleeved on the small-diameter part at the top end of the lower positioning pin column 113 and fall to the top of the buffer slope 114 to complete the positioning, and the sealing ring is aligned with the lower installation groove of the bearing ring;

[0054] To cooperate with the lower pressing head 11, the upper pressing head 12 includes an upper support 121 fixedly installed on the support of the machine body frame, a positioning sliding sleeve 122 vertically slidably installed on the outer surface of the upper support 121, and an upper positioning pin column 123 vertically slidably installed inside the upper support 121. A second limiting spring 124 is installed between the top surface of the upper positioning pin column 123 and the chute of the upper support 121. A third limiting spring 125 is installed between the top surface of the positioning sliding sleeve 122 and the upper support 121. At the same time, a limiting ring groove 128 is formed among the upper positioning pin column 123, the upper support 121 and the positioning sliding sleeve 122. The bottom end of the upper support 121 is circumferentially provided with negative pressure through holes 126 in an array, and an annular channel communicating all the negative pressure through holes 126 is opened inside the upper support 121. A micro negative pressure pump 127 is fixedly installed on the outer support of the upper support 121, and the suction end of the micro negative pressure pump 127 is connected to the annular channel through a pipeline; With this structure, the upper sealing ring can be pushed into the limiting ring groove 128, and the air between the sealing ring and the limiting ring groove 128 can be evacuated through the negative pressure through holes 126 in cooperation with the micro negative pressure pump 127, so that it is sucked tightly and will not fall off, and at the same time, it is completely embedded into the limiting ring groove 128 and aligned with the installation groove on the top surface of the bearing ring to complete the positioning;

[0055] Furthermore, to make the positioning more accurate, an upper convex column 129 protrudes from the bottom surface of the upper positioning pin column 123, and a limiting groove 115 matching the upper convex column 129 is opened on the top surface of the lower positioning pin column 113. In this way, during the pressing process of the lower pressing head 11 and the upper pressing head 12, the upper convex column 129 can be embedded into the limiting groove 115, so that the pressing accuracy is higher and the vertical movement of the pressing is more accurate;

[0056] According to the above structure, during pressing, the upper boss 129 is embedded in the limiting groove 115, and the bottom surface of the second limiting spring 124 is attached to the top surface of the lower positioning pin 113, and the positioning sleeve 122 is attached to the outer ring surface of the bearing ring, and the downward pressure is continuously maintained. Under the action of the downward pressure interaction force, the negative pressure through hole 126 and the upper positioning pin 123 compress the third limiting spring 125 and the second limiting spring 124 respectively to retract, and the lower positioning pin 113 compresses the first limiting spring 116 to shrink, so that the sealing ring above the bearing ring is gradually embedded in the upper mounting groove of the bearing ring under the downward pressure of the positioning sleeve 122, and the sealing ring below is gradually embedded in the lower mounting groove of the bearing ring under the relative action of the lower top plate 112, completing the synchronous installation of the upper and lower sealing rings, thereby improving the processing and assembly efficiency of the bearing ring.

[0057] See attached Figure 5 and Figure 9 , wherein the sealing ring blanking assembly 2 comprises a sealing ring sleeve 21 placed vertically, a first sleeve seat 22 is arranged at the bottom of the sealing ring sleeve 21, the first sleeve seat 22 is suspended and fixed on the body frame through a bracket, a first thin cylinder 23 is arranged directly below the outlet of the first sleeve seat 22, and a first receiving support plate 24 is fixedly installed at the power output end of the first thin cylinder 23, the sealing ring can be placed inside the sealing ring sleeve 21, so that it can slide down by its own gravity when in use, which is simple and convenient, and the sealing ring sleeve 21 is made of transparent material, which can be convenient to observe the amount of the remaining sealing ring, and convenient to add when it is insufficient;

[0058] Furthermore, in order to prevent the sealing ring from falling by itself, a movable stop plate 62 and a fixed stop plate 63 are respectively installed on both sides of the outlet of the first sleeve seat 22, and the movable stop plate 62 and the fixed stop plate 63 extend into the cavity of the sealing ring sleeve 21. At the same time, a pushing cylinder 61 is also installed on the body frame, and a movable stop plate 62 is fixedly installed on the power output end of the pushing cylinder 61.

[0059] According to the above structure, when the sealing ring is not needed, the first thin cylinder 23 pushes up the first receiving support plate 24 to block the outlet to prevent the sealing ring from falling. When the sealing ring is needed, the pushing cylinder 61 pushes the movable stop plate 62 to cooperate with the fixed stop plate 63 to stop the second to last sealing ring below to prevent it from falling. At the same time, the first thin cylinder 23 moves down the first receiving support plate 24 to transmit the sealing ring at the lowest end out, and this cycle is repeated to achieve discharge one by one.

[0060] See attached Figure 2 and Figure 11, wherein, for the convenience of automatically picking up the sealing ring, the sealing ring picking component 4 includes a first clamping jaw 41, a balance support plate 42, a central support plate 43 and a bottom support plate 45. The bottom support plate 45 is fixedly installed on the machine body frame, and a transverse track 46 is fixedly installed on the top surface. The central support plate 43 is horizontally slidably installed on the transverse track 46 through a sliding support. A longitudinal track 44 that is cross - arranged with the transverse track 46 is fixedly installed on the central support plate 43. The balance support plate 42 is longitudinally slidably installed on the longitudinal track 44 through a sliding support.

[0061] Furthermore, in order to provide driving force for the above - mentioned structure, the sealing ring picking component 4 further includes an electric telescopic rod 49 fixedly installed on the side of the central support plate 43, belt pulleys 410 rotatably installed at both ends of the top surface of the bottom support plate 45, and a servo motor 412 installed on the bottom surface of the bottom support plate 45. A belt 411 is sleeved between the belt pulleys 410. The servo motor 412 is in transmission connection with one of the belt pulleys 410. The power output end of the electric telescopic rod 49 is fixedly connected to the balance support plate 42. One side of the central support plate 43 is fixedly connected to one side of the belt 411.

[0062] According to the above - mentioned structure, by driving the two groups of belt pulleys 410 to rotate cyclically through the servo motor 412, the belt 411 can reciprocate between the bottom support plates 45, thereby driving the central support plate 43 to reciprocate along the transverse track 46, so that the first clamping jaw 41 can move left and right between the pressing component 1 and the sealing ring blanking component 2. At the same time, the electric telescopic rod 49 can push the balance support plate 42 to move along the longitudinal track 44, so that the first clamping jaw 41 can move back and forth. At the same time, the third thin - type cylinder 48 can push the first clamping jaw motor 47 to move up and down, thereby realizing the up - and - down movement of the first clamping jaw 41. In summary, the first clamping jaw 41 can realize the axial movement in the X, Y, and Z directions in space. At the same time, cooperating with the first clamping jaw motor 47 to drive the first clamping jaw 41 to clamp the sealing ring, the sealing ring can be taken out from the sealing ring blanking component 2 and accurately placed between the lower pressing head 11 and the upper pressing head 12.

[0063] In this embodiment, two groups of sealing ring blanking components 2 are symmetrically arranged on the left and right sides of the pressing component 1, and two groups of first clamping jaws 41 are arranged in cooperation with them; in other embodiments, only one group of sealing ring blanking components 2 can be arranged on the side of the pressing component 1, and one group of first clamping jaws 41 can be arranged in cooperation with it.

[0064] Refer to the appendix Figure 3 and Figure 10, wherein, the bearing ring blanking assembly 3 includes a vertically placed bearing ring sleeve 31, a second sleeve seat 32 is arranged at the bottom of the bearing ring sleeve 31, the second sleeve seat 32 is suspended and fixed on the machine body frame through a bracket, a second thin cylinder 33 is arranged directly below the outlet of the second sleeve seat 32, a second receiving support plate 34 is fixedly installed at the power output end of the second thin cylinder 33, the bearing ring can be placed into the bearing ring sleeve 31, and it slides down by its own gravity during use, which is simple and convenient. At the same time, the bearing ring sleeve 31 is made of a transparent material, which is convenient to observe the remaining amount of the sealing ring and convenient to add when it is insufficient;

[0065] Further, in order to prevent the bearing ring from falling by itself, movable stop plates 62 and fixed stop plates 63 are respectively installed on both sides of the outlet of the second sleeve seat 32, and the movable stop plates 62 and the fixed stop plates 63 extend into the cavity of the bearing ring sleeve 31. At the same time, a pushing cylinder 61 is also installed on the machine body frame, and the movable stop plate 62 is fixedly installed at the power output end of the pushing cylinder 61;

[0066] According to the above structure, when the sealing ring is not needed, the second receiving support plate 34 is pushed up by the second thin cylinder 33 to block the outlet and prevent the sealing ring from falling. When the sealing ring is needed, the pushing cylinder 61 is used to push the movable stop plate 62 to cooperate with the fixed stop plate 63 to hold the second-to-last bearing ring below to prevent it from falling. At the same time, the second thin cylinder 33 moves the second receiving support plate 34 downward to convey the sealing ring at the lowest end. This cycle is repeated to achieve discharging one by one.

[0067] Refer to the appendix Figure 3 and Figure 12 , in order to automatically pick up the bearing ring, the bearing ring picking assembly 5 includes a second clamping jaw 51, a support cross plate 52, and a rotating motor 55 fixedly installed on the machine body frame. A rotating support plate 56 is fixedly installed at the power output end of the rotating motor 55, a fourth thin cylinder 54 is fixedly installed on the rotating support plate 56, the support cross plate 52 is fixedly installed at the power output end of the fourth thin cylinder 54, a second clamping jaw motor 53 is fixedly installed at one end of the support cross plate 52 away from the fourth thin cylinder 54, and the second clamping jaw 51 is fixedly installed at the power output end of the second clamping jaw motor 53. The rotating motor 55 drives the fourth thin cylinder 54 to rotate through the rotating support plate 56. At the same time, the fourth thin cylinder 54 expands and contracts up and down to drive the support cross plate 52 to move up and down, and cooperates with the second clamping jaw motor 53 to drive the second clamping jaw 51, which can realize clamping the bearing on the bearing ring blanking assembly 3 at a fixed distance, and at the same time, it is transmitted in the rotating direction between the lower pressing head 11 and the upper pressing head 12. At the same time, it moves up and down and uses the second clamping jaw 51 to place the bearing on the lower pressing head 11. And after the bearing assembly is completed, the second clamping jaw 51 can be used again to pick up the bearing, place it on the slideway 58, and slide into the collection hopper 57 to be collected.

[0068] The working principle of the present invention is as follows: When in use, first, put seals and bearing rings into the two seal ring sleeves 21 and bearing ring sleeves 31 respectively. Then, start the seal taking and placing assembly 4. Use one of the first clamping claws 41 to pick up the seal and place it on the top end of the lower positioning pin 113, and apply force downward to make it slide down along the buffer slope 114 and sleeve on the large diameter at the bottom end of the lower positioning pin 113. At the same time, place it on the surface of the lower top plate 112. Since the large diameter at the bottom end of the lower positioning pin 113 is the same as its inner diameter, and in cooperation with the lower top plate 112, it is accurately positioned. Then, use the second clamping claw 51 to pick up the bearing ring and also place it on the lower positioning pin 113, and apply force downward to make it sleeved on the small diameter at the top end of the lower positioning pin 113 and fall to the top of the buffer slope 114 to complete the positioning. Thus, the installation groove of the bearing ring is aligned with the seal. After that, use the other second clamping claw 51 to pick up the seal on the other side and apply force upward to push it into the limiting ring groove 128. At the same time, use the micro negative pressure pump 127 to evacuate the air between the seal and the limiting ring groove 128 through the negative pressure through hole 126, so that it is sucked tightly and will not fall off, and at the same time is completely embedded into the limiting ring groove 128 and aligned with the installation groove on the top surface of the bearing ring to complete the positioning;

[0069] Secondly, use the pressing hydraulic cylinder 15 to press down the upper pressing head 12, so that the upper convex column 129 is embedded into the limiting groove 115 to improve the positioning accuracy. At the same time, the bottom surface of the second limiting spring 124 fits on the top surface of the lower positioning pin 113, and the positioning sliding sleeve 122 fits on the outer surface of the bearing ring. Keep pressing down. Under the action of the downward pressing force, the negative pressure through hole 126 and the upper positioning pin 123 respectively compress the third limiting spring 125 and the second limiting spring 124 to retract. At the same time, the lower positioning pin 113 compresses the first limiting spring 116 to contract. Thus, the seal above the bearing ring is gradually embedded into the upper installation groove of the bearing ring under the pressing of the positioning sliding sleeve 122, and the seal below is gradually embedded into the lower installation groove of the bearing ring under the relative action of the lower top plate 112 until the installation is completed;

[0070] Finally, use the pressing hydraulic cylinder 15 to separate the lower pressing head 11 and the upper pressing head 12, and the positioning sliding sleeve 122, the upper positioning pin 123 and the lower positioning pin 113 are reset under the action of the rebounding force. At the same time, use the second clamping claw 51 to pick up the assembled bearing, place it on the slideway 58, and slide into the collecting hopper 57 to be collected. At the same time, start the assembly of the next bearing ring, and repeat the process until the assembly of all bearing rings and seals is completed.

[0071] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention are implemented according to the conventional means in the art without special explanation and limitation.
