Description

Technical Field

[0001] This invention relates to the field of bearing processing technology, and in particular to a bearing processing machine tool transport mechanism. Background Technology

[0002] In the field of wheel bearing manufacturing, machining is the core process ensuring high-precision manufacturing of wheel bearings. Its quality directly affects the assembly compatibility, operational stability, and service life of the wheel bearing. Wheel bearings have diverse structural forms; not all are regular cylindrical structures. Some products consist of cylindrical segments of different diameters, forming a stepped structure. For wheel bearings with such tapered structures, the manufacturing process explicitly requires separate machining of each different surface to ensure that the dimensional accuracy and geometric tolerances of each part meet the product design and usage requirements.

[0003] In the current actual wheel hub bearing processing flow, after the machining device completes the cutting of the tapered surface of the wheel hub bearing, it needs to be transferred to the next machining device using a lifting and transfer device to perform the cutting operation on the cylindrical surface. However, existing lifting and transfer technologies have shortcomings. First, the positioning stability of the wheel hub bearing during the transfer process is difficult to guarantee reliably, and it is easily affected by factors such as vibration and tilting during the transfer process, resulting in positional deviations and causing accuracy deviations in subsequent cutting processes. Second, the automation integration and transfer efficiency of existing transfer methods are low, resulting in a lack of continuity in the process connection between various machining devices, causing a mismatch in the processing cycle and affecting the overall production efficiency of wheel hub bearing processing. Summary of the Invention

[0004] This invention provides a transport mechanism for bearing processing machine tools to solve the problems of insufficient positioning stability leading to cutting accuracy deviation, low automation and efficiency resulting in poor process connection and reduced production efficiency in current wheel hub bearing processing lifting and transfer devices.

[0010] The right-angle frame has a sliding groove, and a sliding shaft is slidably arranged in the sliding groove. A spring is connected between the sliding shaft and the inner wall of the groove. One end of the sliding shaft is connected to an oil injection nozzle. The bottom end of the oil injection nozzle is spherical and connected to one end of the hose. A one-way valve is provided at the connection between the oil injection nozzle and the hose. A spring is sleeved on the sliding shaft. One end of the spring is connected to the upper surface of the oil injection nozzle, and the other end is connected to one end of the sliding shaft. An oil injection component is connected to the clamping bearing. The oil injection component has an inner concave hole for oil injection.

[0011] Furthermore, the arched support is provided with a compression unit on its side. The compression unit includes two sets of symmetrical side frames fixed to the side of the arched support.

[0012] Furthermore, the sealing assembly includes a through rod that extends through the side frame. A sealing element is fixed to one end of the through rod.

In the initial state, the sealing elements are in contact with each other under the action of the spring three.

[0013] Furthermore, two sets of pushing units are fixed on the fixed base, and the two sets of pushing units are arranged vertically.

[0035] 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, structure, features and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0036] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] Reference Figure 1 and Figures 5-6As shown, the present invention provides a bearing processing machine tool transport mechanism, including a processing table 1, with a protective cover 11 above the processing table 1, and a mounting base plate 13 fixed on the surface of the processing table 1. Two sets of feeding components 2 are provided on the processing table 1, and the two sets of feeding components 2 are respectively used for the double cutting processing of a single bearing, and are arranged in a stepped downward layout from left to right to adapt to the process requirements of double cutting of bearings. The feeding component 2 includes a feeding channel 21 fixed to the side of the mounting base plate 13 and inclinedly arranged. The feeding channel 21 is used for the orderly conveying of bearings, so that the bearings fall one by one along the inclined direction. The feeding channel 21 is movably arranged through the left side of the protective cover 11 to realize the initial receiving of bearings.

[0038] An electric push rod 22 is fixed to the back of the mounting base 13. A sliding seat 23 is fixed to the telescopic end of the electric push rod 22. A groove 14 for the sliding seat 23 to slide horizontally is provided on the mounting base 13. A concave frame 24 is fixed to the side of the sliding seat 23. A feeding component 25 is movably mounted on the concave frame 24. The feeding component 25 has a discharge arc groove 27 for receiving the bearing at one end near the feeding channel 21, so as to achieve precise receiving and positioning of the bearing. The other end is connected to the concave frame 24 by a tension spring 26. The tension spring 26 is in a stretched state to provide a reset force for the feeding component 25. The tension spring 26 keeps the feeding component 25 initially in a horizontal state. In the default state, the end of the feeding component 25 with the discharge arc groove 27 extends out of the feeding channel 21, which can continuously receive the bearings arranged in the feeding channel 21. The mounting base plate 13 is provided with a baffle plate (not shown in the figure) on the side to control the number of bearings falling at one time and stabilize the feeding rhythm.

[0039] like Figures 3-5 and Figure 7 As shown, the processing table 1 is equipped with two sets of clamping assemblies 3, which cooperate with two sets of feeding assemblies 2 to achieve the next clamping operation of the bearing. The clamping assembly 3 includes a base 31 fixed on the processing table 1, a linear module 32 fixed on the base 31, a slider 33 on the linear module 32, a fixed seat 34 fixed on the slider 33, and a clamping bearing 35 connected to the fixed seat 34. At the same time, the mounting base 13 is equipped with two sets of driving assemblies, which cooperate with the two sets of feeding assemblies 2 to clamp the bearing. The driving assembly includes a driving member 37 fixed on the mounting base 13, and the output end of the driving member 37 passes through the mounting base 13 and is fixed with a rotating disk 36. The rotating disk 36 is coaxially arranged with the clamping bearing 35.

[0040] Bearings in the feeding channel 21 fall one by one along the inclined direction, with the baffle plate controlling only one bearing to fall at a time. The initially horizontal feeding component 25 accurately receives and positions the bearing through the discharge arc groove 27, and the tension spring 26 continuously provides a restoring force to keep the feeding component 25 in a stable position. Subsequently, the electric push rod 22 drives the sliding seat 23 to move horizontally along the slide groove 14, driving the concave frame 24, the feeding component 25 and the bearing to move synchronously to the corresponding clamping assembly 3. The two sets of stepped feeding assemblies 2 sequentially complete the transfer of the bearing between the dual cutting processes. After the bearing is transferred to the clamping station, the linear module 32 drives the slider 33 to move the fixed seat 34 and the clamping bearing 35 toward the bearing. This works in conjunction with the rotating disk 36 driven by the drive unit 37 on the mounting base 13 (the two are coaxially arranged) to achieve precise clamping of the bearing. At this time, the electric push rod 22 drives the feeding component 25 to reset. Since the bearing has been clamped by the rotating disk 36 and the clamping bearing 35, the feeding component 25 will stretch the tension spring 26 when it resets until the feeding component 25 is completely detached from the clamped bearing.

[0041] To achieve machining of the bearing after clamping, such as Figures 1-4 As shown, the machining table 1 is equipped with a first cutting assembly 7 and a second cutting assembly 6. The second cutting assembly 6 is used to perform cutting operations on the bearing held by the subsequent clamping assembly 3 and the drive assembly, while the first cutting assembly 7 is used to perform cutting operations on the bearing held by the preceding clamping assembly 3 and the drive assembly. The first cutting assembly 7 cuts the tapered surface of the bearing, while the second cutting assembly 6 cuts the cylindrical surface of the bearing. Since their structures are similar, only the structure and working principle of the first cutting assembly 7 will be described below.

[0042] The first cutting assembly 7 includes a second linear module 71 fixed on the processing table 1. The second linear module 71 is provided with a sliding base 72. An inclined mounting rod 73 is fixed on the sliding base 72. An electric push rod 74 parallel to the mounting rod 73 is fixed on the mounting rod 73. A cutting block 75 is fixed at the telescopic end of the electric push rod 74. The cutting block 75 is used to accurately align the cutting position of the bearing, thereby completing the cutting of the tapered surface of the bearing. An inclined discharge channel 12 is provided on the side of the mounting base 13 and through the right side of the protective cover 11. The discharge channel 12 is used to receive the bearing after being cut by the second cutting assembly 6.

[0043] It should be noted that after the bearing is transferred and clamped by the preceding feeding assembly 2, clamping assembly 3 and driving assembly, the first cutting assembly 7 first cuts its conical surface; after the bearing is processed, it falls into the feeding channel 21 of the subsequent feeding assembly 2, and then through the cooperation of the subsequent feeding assembly 2, clamping assembly 3 and driving assembly, the second cutting assembly 6 cuts its cylindrical surface.

[0044] After the bearing is precisely clamped by the clamping assembly 3 and the drive assembly, the first cutting assembly 7 and the second cutting assembly 6 perform cutting operations in sequence: the linear module 71 drives the sliding base 72 to move the mounting rod 73, the electric push rod 74 and the cutting block 75, so that the cutting block 75 is precisely aligned with the tapered surface of the bearing clamped in the previous step, and the electric push rod 74 pushes the cutting block 75 to complete the tapered surface cutting; at the same time, the second cutting assembly 6, based on a similar principle, is driven by its linear module to move the corresponding sliding base 72 and the cutting structure, aligning with the cylindrical surface of the bearing clamped in the subsequent step, and the electric push rod pushes the cutting block 75 to complete the cylindrical surface cutting. The two work together to achieve the orderly completion of the dual cutting process of the bearing.

[0045] To achieve cooling during bearing cutting, such as Figure 5 and Figure 7 As shown, a cooling assembly 5 is provided on the side of the protective cover 11. The cooling assembly 5 includes a liquid storage tank 51 fixed to the side of the protective cover 11, which stores cutting fluid; the bottom of the liquid storage tank 51 is connected to a liquid injection pipe 53, one end of which is connected to two sets of drain pipes 52. The drain pipes 52 are used to precisely align with the bearing cutting positions of the two machining areas, thereby cooling the bearing during the cutting process.

[0046] To address the frictional force generated between the clamping bearing 35 and its own shaft due to relative rotation when the clamping bearing 35 and the rotating disk 36 of the drive assembly clamp the bearing and drive its rotation, lubrication of this mating part is necessary. Figures 8-12 As shown, both sets of clamping assemblies 3 have a base 31 on which a lubrication assembly 4 is provided. The lubrication assembly 4 includes an arched support 401 fixed to the base 31, and a right-angle frame 41 fixed to the side of the arched support 401. An oil storage bottle 42 is vertically arranged on the right-angle frame 41. The oil storage bottle 42 stores lubricating oil. The bottom of the oil storage bottle 42 is connected to a piston cylinder 48 through a pipe. A one-way valve is provided at the connection between the piston cylinder 48 and the oil storage bottle 42. The one-way valve allows the lubricating oil in the oil storage bottle 42 to be discharged only. A hose 49 is connected to one end of the piston cylinder 48. The hose 49 is used to transport the lubricating oil squeezed out of the piston cylinder 48.

[0047] Meanwhile, a sliding groove (not shown in the figure) is provided on the right-angle bracket 41, and a sliding shaft (not shown in the figure) is slidably installed in the groove. A spring 411 is connected between the sliding shaft and the inner wall of the groove. One end of the sliding shaft is connected to an oil injection nozzle 410. The bottom end of the oil injection nozzle 410 is spherical and is connected to one end of the hose 49. A one-way valve is provided at the connection between the oil injection nozzle 410 and the hose 49 so that the lubricating oil in the hose 49 can only be injected into the oil injection nozzle 410. A spring 413 is sleeved on the sliding shaft. One end of the spring 413 is connected to the upper surface of the oil injection nozzle 410, and the other end is connected to one end of the sliding shaft. An oil injection component 414 is connected to the clamping bearing 35. The oil injection component 414 has an oil injection concave hole. When the clamping bearing 35 is brought close by the linear module 32, it can push the oil injection nozzle 410 upward to squeeze the spring 413 until the oil injection nozzle 410 is embedded in the oil injection concave hole.

[0048] Furthermore, an extrusion unit is provided on the side of the arch support 401. The extrusion unit includes two sets of symmetrical side frames 81 fixed on the side of the arch support 401. An arch frame 43 is fixed on the side of one set of side frames 81, and a gear 44 is provided on the side bearing of the arch frame 43. A piston rod 47 is movably provided at one end of the piston cylinder 48. The surface of the piston rod 47 has a spiral groove, which movably passes through the side frame 81, is threadedly connected to the gear 44, and movably passes through the arch frame 43. A limiting ring 45 is movably sleeved at one end of the piston rod 47. A guide rod 46 is fixed on the limiting ring 45 and movably passes through the side frame 81. A rack 412 is fixed on the side of the fixed seat 34, and the rack 412 meshes with the gear 44. When the fixed seat 34 is reset by the linear module 32, the rack 412 synchronously drives the gear 44 to rotate, thereby causing the piston rod 47 to squeeze the lubricating oil in the piston cylinder 48 and deliver it to the oil nozzle 410 through the hose 49; when the fixed seat 34 moves closer to the rotating disk 36 by the linear module 32, the piston rod 47 pulls the piston cylinder 48, allowing the lubricating oil in the oil reservoir 42 to enter the piston cylinder 48 through the one-way valve.

[0049] To address the issue that when the fixed base 34 is moved close to the rotating disk 36 by the linear module 32, the oil injection part 414 is exposed and needs to be sealed, such as... Figures 11-13 As shown, sealing components 8 are provided on the sides of the two sets of side frames 81. The sealing component 8 includes a through rod 82 with a T-shaped cross-section that moves through the side frame 81. A sealing element 84 is fixed to one end of the through rod 82. The two sets of sealing elements 84 can be joined together to form a hollow columnar structure for sealing the oil nozzle 410. A spring 83 is sleeved on the through rod 82. One end of the spring 83 is connected to the inner side of the side frame 81, and the other end is connected to the side of the oil nozzle 410. In the initial state, the sealing elements 84 are pressed together by the action of the spring 83 to seal the oil nozzle 410.

[0050] Meanwhile, two sets of pushing units are fixed on the fixed base 34. These two sets of pushing units are arranged vertically, and each pushing unit acts on one of the two sets of sealing components 8, so that before the oil injection component 414 aligns with the oil injection nozzle 410, it pushes the two sets of sealing components 84 to move to both sides. Each pushing unit includes a straight rod 85 fixed on the fixed base 34. The two sets of pushing units have straight rods 85 of different lengths, which are shown here as follows: Figure 11 For example, the straight rod 85 on the left is defined as the first straight rod, and the straight rod 85 on the right is defined as the second straight rod. The straight distance between the first straight rod and the fixed seat 34 is less than the straight distance between the second straight rod and the fixed seat 34. A contact rod 88 is fixed on the bottom surface of the sealing member 84. At the same time, a bent member 87 is provided on the side of the two sets of straight rods 85. One end of the bent member 87 contacts the side of the contact rod 88, and the other end of the bent member 87 has an arc-shaped part. The arc-shaped part contacts the contact rod 88 when the fixed seat 34 is reset with the linear module 32. A magnet 89 is fixed on the side of the bent member 87 connected to the first straight rod near the oil injection member 414. At the same time, a magnet 2 (not shown in the figure) is fixed on the side of the oil injection member 414 near the magnet 89.

[0051] It should be noted that, in the initial state, the two sets of seals 84 will adhere to each other under the elastic force of spring 83, thereby enclosing the oil injection nozzle 410 and sealing it. During actual processing, the fixed seat 34 will be driven by the linear module 32 to move towards the rotating disk 36, thus clamping the bearing. Simultaneously, the rotating disk 36 will rotate under the drive of the drive component 37, thereby causing the clamping bearing 35 to rotate synchronously.

[0052] After the bearing machining is completed, the clamping bearing 35 will begin to reset and move under the action of the linear module 32. Due to the previous rotation driven by the drive component 37, the clamping bearing 35 will rotate due to inertia. During the reset and movement of the fixed seat 34 with the linear module 32, the oil injection component 414 on the clamping bearing 35 will also rotate due to inertia until it gradually contacts the first straight rod. This is because the straight distance between the first straight rod and the fixed seat 34 is smaller than the straight distance between the second straight rod and the fixed seat 34.

[0053] When the oiling component 414 contacts the first straight rod, the second magnet on the oiling component 414 will attract the first magnet 89 on the side of the bent part 87 on the first straight rod, thus keeping the oiling component 414 in a vertically upward position. In this state, the oiling component 414 can accurately approach and align with the oiling concave hole, preparing for subsequent oiling operations.

[0054] Working principle: The bearings in the feeding channel 21 fall one by one along the inclined direction, and the baffle plate controls that only one bearing falls at a time; the initially horizontal feeding part 25 accurately receives and positions the bearing through the discharge arc groove 27, and the tension spring 26 continuously provides the reset force to keep the feeding part 25 stable. Then, the electric push rod 22 drives the sliding seat 23 to move horizontally along the slide groove 14, which drives the concave frame 24, the feeding part 25 and the bearing to move synchronously to the corresponding clamping assembly 3. The two sets of stepped feeding assemblies 2 sequentially complete the transfer of the bearing between the double cutting processes. After the bearing is transferred to the clamping station, the linear module 32 drives the slider 33 to move the fixed seat 34 and the clamping bearing 35 toward the bearing. This works in conjunction with the rotating disk 36 driven by the drive unit 37 on the mounting base 13 (the two are coaxially arranged) to achieve precise clamping of the bearing. At this time, the electric push rod 22 drives the feeding component 25 to reset. Since the bearing has been clamped by the rotating disk 36 and the clamping bearing 35, the feeding component 25 will stretch the tension spring 26 when it resets until the feeding component 25 is completely detached from the clamped bearing.

[0055] After the bearing is precisely clamped, the first cutting assembly 7 and the second cutting assembly 6 perform cutting operations in sequence: the linear module 71 drives the sliding base 72 to move the mounting rod 73, the electric push rod 74, and the cutting block 75, so that the cutting block 75 is precisely aligned with the conical surface of the bearing clamped in the previous step. The electric push rod 74 pushes the cutting block 75 to complete the conical surface cutting. The bearing with the conical surface cut falls into the feeding channel 21 of the subsequent feeding assembly 2. After the subsequent feeding assembly 2, clamping assembly 3 and driving assembly work together, the second cutting assembly 6 aligns with the cylindrical surface of the bearing clamped in the subsequent step using a similar principle. The electric push rod pushes the cutting block 75 to complete the cylindrical surface cutting. During the cutting process, the liquid storage tank 51 of the cooling assembly 5 accurately delivers the cutting fluid to the bearing cutting position in the two processing areas through the injection pipe 53 and the drain pipe 52 to achieve cooling. The bearing with the cylindrical surface cut is finally received and discharged by the inclined discharge channel 12 that runs through the right side of the protective cover 11.

[0056] When the fixed seat 34 moves closer to the rotating disk 36 under the action of the linear module 32, the piston rod 47 pulls the piston cylinder 48, and the lubricating oil in the oil reservoir 42 enters the piston cylinder 48 through the one-way valve. At this time, in the sealing assembly 8, the straight rod 85 on the fixed seat 34 pushes the contact rod 88 through the bent part 87, causing the two sets of seals 84 to move to both sides, releasing the seal on the oil filling nozzle 410 and preparing the channel for subsequent oil filling. When the fixed seat 34 is reset by the linear module 32, the rack 412 on the side of the fixed seat 34 synchronously drives the gear 44 to rotate, causing the piston rod 47 to squeeze the lubricating oil in the piston cylinder 48, which is then delivered to the oil injection nozzle 410 through the hose 49 and the one-way valve 2. At the same time, when the clamping bearing 35 moves as the linear module 32 resets, the oil injection component 414 on it rotates due to inertia. After contacting the first straight rod, it is kept vertically upward by the attraction of magnet 89 and magnet 2, which precisely pushes the oil injection nozzle 410 upward to squeeze the spring 2 413 until the oil injection nozzle 410 is completely embedded in the oil injection concave hole of the oil injection component 414. The lubricating oil delivered to the oil injection nozzle 410 is directly injected into the mating part between the clamping bearing 35 and its own rotating shaft, achieving precise lubrication and reducing relative rotational friction.

[0057] In the initial state, the two sets of seals 84 of the sealing assembly 8 are pressed together by the action of spring 3 83, sealing the oil injection nozzle 410 and preventing lubricating oil leakage and impurities from entering the oil injection channel. After the machining is completed and the fixed seat 34 is reset to the initial position, the oil injection component 414 remains vertically aligned under the attraction of magnet 1 89 and magnet 2 until the fixed seat 34 is driven by linear module 1 32 to approach the rotating disk 36 again. At this point, the oil injection component 414 moves with the clamping bearing 35 and disengages from the magnet, resuming its rotation state. Meanwhile, the seals 84 are pressed together again to seal the oil injection nozzle 410 under the elastic force of spring 3 83, completing the cycle of sealing-unlocking-oiling-resealing, achieving the coordination of lubrication and sealing, and ensuring the long-term stable operation of the equipment.
