Description

Technical Field

[0001] This utility model belongs to the field of grinding machine technology, and specifically relates to a rotor ultra-precision grinding machine. Background Technology

[0002] The rotor needs to be ground and polished to remove burrs and sharp edges generated on the rotor surface during processing, thereby reducing the surface roughness of the rotor, lowering the coefficient of friction, and improving the rotor's wear resistance.

[0003] However, existing grinding machines are inefficient, and there is a lot of resistance between the abrasive and the rotor during the grinding process. Utility Model Content

[0004] The purpose of this invention is to provide a rotor ultra-precision grinding machine to solve one or more technical problems existing in the prior art.

[0005] The technical solution adopted to solve the above-mentioned technical problems is as follows: This utility model discloses a rotor ultrafine grinding machine, comprising: A frame, the frame including a base, a lifting base and a grinding barrel, the lifting base being located above the grinding barrel; A drive mechanism, comprising a drive component with a transmission connection and multiple workstations, wherein the drive component is connected to the lifting seat, and the output end of the drive component is configured to drive the multiple workstations to rotate, and each workstation has a working end detachably connected to the rotor; A lifting mechanism is provided, which is connected to the base. The output end of the lifting mechanism is connected to the lifting seat. The lifting seat is configured such that when the lifting seat is raised to a first position, the rotor connected to the working end is located inside the grinding barrel; and when the lifting seat is raised to a second position, the rotor connected to the working end is located above the grinding barrel. A guiding mechanism is configured such that, when the lifting seat is in the first position, the guiding mechanism fixes the lifting seat and the base relative to each other in a tapered manner.

[0006] The present invention has at least the following beneficial effects: the output end of the lifting mechanism drives the lifting seat to rise and fall to the second position, and multiple rotors are respectively installed on multiple working ends through a detachable connection. The lifting mechanism is restarted, driving the lifting seat to rise and fall to the first position. Abrasive is placed in the grinding barrel in advance. At this time, multiple rotors move into the grinding barrel with the movement of the lifting seat. The drive mechanism is started, and the output end of the drive mechanism drives multiple working ends and multiple rotors to rotate at one time, improving grinding efficiency and saving the installation cost of the drive mechanism. Multiple rotors rotate and rub against the abrasive in the grinding barrel to perform grinding processing on the rotors. The frictional resistance between the rotors and the abrasive is transmitted between the lifting seat and the machine base. The guide mechanism fixes the lifting seat and the machine base relatively in a tapered manner. The tapered fit of the guide mechanism bears the resistance between the abrasive and the rotating rotors, avoiding problems such as reduced rotor speed, increased load on the drive mechanism, abnormal vibration and loud noise between the lifting seat and the machine base, and decreased grinding efficiency.

[0007] After the grinding process is completed, the drive mechanism is turned off and the lifting mechanism is restarted. The output end of the lifting mechanism drives the lifting seat to the second position again. At this time, the ground rotor is located above the grinding barrel, which makes it easy for people to disassemble and reinstall a new rotor to be ground.

[0008] As a further improvement to the above technical solution, the guiding mechanism includes a cone sleeve and a cone member. The cone sleeve is connected to the lifting seat, and the cone member is connected to the machine base. When the lifting seat moves to the first position, the cone member is fitted into the cone sleeve.

[0009] As a further improvement to the above technical solution, the tapered sleeve is provided with a first fastener, a first screw hole and a relief groove. The first fastener passes through the first screw hole and is threaded to the lifting seat. The head of the first fastener is hidden in the relief groove.

[0010] As a further improvement to the above technical solution, the guiding mechanism also includes a guide shaft and a guide sleeve that are slidably connected. The guide sleeve is connected to the lifting seat, and the guide shaft passes through the guide sleeve. The guide shaft extends vertically and both ends are connected to the machine base.

[0011] As a further improvement to the above technical solution, the conical sleeve and the guide sleeve are integrally formed, and the conical part is connected to the lower end of the guide shaft.

[0012] As a further improvement to the above technical solution, the lifting seat is rotatably connected to a main shaft sleeve, and the two ends of the main shaft sleeve are respectively connected to the output end of the driving component and the multiple workstations.

[0013] As a further improvement to the above technical solution, the drive mechanism further includes a first transmission component, which includes a first turntable, a driving gear and a plurality of driven gears. The main shaft sleeve is coaxially connected to the first turntable and the driving gear. The first turntable is rotatably connected to the plurality of driven gears. The driving gear is meshed with the plurality of driven gears. Each driven gear is connected to a plurality of workstations.

[0014] As a further improvement to the above technical solution, the drive mechanism further includes a plurality of second transmission components. The second transmission components include a second turntable, a first gear and a plurality of second gears. The driven gear is coaxially connected to the second turntable and the first gear. The second turntable is rotatably connected to the plurality of second gears. The first gear is meshed with the plurality of second gears. Each second gear is connected to each of the workstations.

[0015] As a further improvement to the above technical solution, the working end is provided with a second screw hole and a second fastener. The second screw hole is opposite to the third screw hole of the rotor head. The working end is the end of the rotor head that is fitted into the station. The second fastener is threadedly connected to the third screw hole and the second screw hole.

[0016] As a further improvement to the above technical solution, the rotor ultra-precision grinding machine also includes a transition shaft. The two ends of the transition shaft are respectively two connecting ends that are fitted and connected to the working end and the rotor. Two second fasteners are provided. The transition shaft is configured such that when the distance between the third screw hole and the rotor end face is greater than the distance between the second screw hole and the station end face, the two connecting ends are respectively threadedly connected to the working end and the rotor through the two second fasteners.

[0023] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0024] Reference Figures 1 to 7 The following are several embodiments of the rotor ultra-precision grinding machine of this utility model.

[0025] like Figures 1 to 7 As shown, the rotor ultrafine grinding machine 100 of this utility model embodiment includes a frame 200, a drive mechanism 300, a lifting mechanism 500, and a guide mechanism 600.

[0026] It is understood that the frame 200 includes a base 210, a lifting base 220, and a grinding barrel 230, such as Figure 1 As shown. Specifically, the base 210 stands upright on the ground, providing support for structures such as the lifting mechanism 500 and the lifting seat 220. The lifting seat 220 is slidably connected to the base 210, and slides relative to the base 210 in the vertical direction, positioned above the grinding barrel 230. The grinding barrel 230 stands upright on the ground with its opening facing upwards, and can hold the corresponding abrasive material according to the required roughness of the rotor 400. In this embodiment, the abrasive material is used to achieve a surface roughness of level ten, i.e., 0.2 micrometers, on the surface of the rotor 400.

[0027] It is understandable that the drive mechanism 300 includes a drive component 310 and multiple workstations 320, such as Figure 2 and Figure 3 As shown. Specifically, the drive unit 310 is connected to the lifting base 220, and the output end of the drive unit 310 is connected to multiple workstations 320, causing the multiple workstations 320 to rotate. Each workstation 320 includes a working end 321, such as... Figure 3 and Figure 4As shown, the working end 321 is detachably connected to the rotor 400. Thus, multiple rotors 400 are pre-connected to the working ends 321 of multiple workstations 320. Then, the drive unit 310 is activated, and its output drives the multiple workstations 320 and the rotors 400 connected to them to rotate. After the rotors 400 have finished grinding, the drive unit 310 is turned off, the rotors 400 are detached from the working ends 321, and the rotors 400 to be ground are reconnected to the working ends 321.

[0028] It is understandable that the lifting mechanism 500 is connected to the base 210, and the two are relatively fixed. The output end of the lifting mechanism 500 is connected to the lifting seat 220. Since the lifting seat 220 is connected to the drive mechanism 300, when the lifting mechanism 500 is started, the output end of the lifting mechanism 500 can drive the lifting seat 220 and the drive mechanism 300 to descend, so that the lifting seat 220 is in the first position. At this time, the rotor 400 connected to the working end 321 can move down into the grinding barrel 230, and multiple rotors 400 simultaneously make full contact with the abrasive in the grinding barrel 230. When the drive mechanism 300 is started, multiple rotors 400 can perform the grinding process simultaneously, improving the grinding efficiency of the rotors 400. The output end of the lifting mechanism 500 can also drive the lifting seat 220 and the drive mechanism 300 to move upward, so that the lifting seat 220 is in the second position, such as... Figure 1 As shown, at this time, the rotor 400 connected to the working end 321 can be moved up to the top of the grinding barrel 230, which makes it convenient to remove the multiple rotors 400 that have been ground from the working end 321 and install new multiple rotors 400 to be ground.

[0029] Understandably, when the lifting seat 220 is in the first position, i.e., the rotor 400 is inside the grinding barrel 230, if the drive mechanism 300 is activated, there will be significant resistance between the rotor 400 and the grinding material. During the grinding process, this resistance needs to be borne by the sliding structure between the lifting seat 220 and the machine base 210. Therefore, when the output end of the lifting mechanism 500 moves the lifting seat 220 down to the first position, the guide mechanism 600 uses a tapered fit to fix the lifting seat 220 and the machine base 210 relatively, preventing problems such as a decrease in the rotor 400's speed, an increase in the load on the rotor ultra-precision grinder 100, abnormal vibration and excessive noise, and reduced grinding efficiency.

[0030] In this embodiment, the base 210 has a cuboid structure, the lifting seat 220 has a square plate shape, and the grinding barrel 230 has a cylindrical shape. The four corners of the lifting seat 220 are slidably connected to the base 210. Two lifting mechanisms 500 are provided and are respectively located at the left and right ends of the base 210. The output ends of the two lifting mechanisms 500 are respectively connected to the lower left and lower right ends of the lifting seat 220.

[0031] It is understood that the lifting mechanism 500 can be a linear motion mechanism such as a hydraulic cylinder or an electric cylinder. In this embodiment, the lifting mechanism 500 is a pneumatic cylinder.

[0032] It is understandable that the guide mechanism 600 includes a cone sleeve 610 and a cone member 620, such as Figure 1 As shown, the base 210 and the lifting seat 220 in the first position are stably connected by the conical surface of the conical member 620 fitting into the conical groove 611 of the conical sleeve 610.

[0033] In this embodiment, the cone sleeve 610 is connected to the lower end face of the lifting seat 220. The cone sleeve 610 has a downward-facing cone groove 611, which has an inner conical surface that is smaller at the top and larger at the bottom. The cone member 620 is connected to the upper end face of the machine base 210, and has an outer conical surface that is smaller at the top and larger at the bottom. The cone sleeve 610 and the cone member 620 are vertically aligned. Therefore, when the lifting seat 220 descends to the first position, the cone sleeve 610 descends with the lifting seat 220 and is fitted onto the outside of the cone member 620. The inner conical surface of the cone sleeve 610 and the outer conical surface of the cone member 620 are fitted together.

[0034] In other embodiments, the cone sleeve 610 has an upward-facing opening and is connected to the lower end face of the lifting seat 220, and the cone groove 611 has an inner conical surface that is larger at the top and smaller at the bottom. The cone 620 is connected to the upper end face of the base 210, and the cone 620 has an outer conical surface that is larger at the top and smaller at the bottom. When the lifting seat 220 descends to the first position, the cone 620 moves down with the lifting seat 220 and is embedded in the cone sleeve 610.

[0035] It is understandable that the tapered sleeve 610 is provided with a first fastener and a first threaded hole 612. Specifically, the first threaded hole 612 extends in the vertical direction, such as... Figure 7 As shown, the first fastener passes through the first screw hole 612 and is threadedly connected to the lifting seat 220, thereby connecting the tapered sleeve 610 and the lifting seat 220.

[0036] Understandably, the cone sleeve 610 also has a clearance groove 613, which is located above the cone groove 611, such as... Figure 7 As shown. The first fastener is threaded from bottom to top through the first screw hole 612 and the lifting seat 220. The head of the first fastener is hidden in the relief groove 613, which avoids the head of the first fastener interfering with the fit between the cone sleeve 610 and the cone 620. It also hides the connection structure between the lifting seat 220 and the cone sleeve 610, making the cone sleeve 610 simple in structure, stable in connection, and the rotor ultra-precision grinding machine 100 neat in appearance.

[0037] It is understandable that the clearance groove 613 is a cylindrical groove.

[0038] Understandably, the first fastener is a screw or bolt.

[0039] In this embodiment, there are four tapered sleeves 610, which are respectively located at the four right-angled corners of the square lifting seat 220. Each tapered sleeve 610 is provided with four first screw holes 612. Correspondingly, four first fasteners stably connect the tapered sleeve 610 to the lifting seat 220.

[0040] It is understandable that the guide mechanism 600 also includes a guide shaft 630 and a guide sleeve 640 with a sliding connection, such as Figure 1 As shown. Specifically, the guide shaft 630 extends vertically, and its two ends are fixedly connected to the base 210, making it stably upright on the base 210. The guide sleeve 640 is connected to the lifting seat 220, and the guide shaft 630 slides through the guide sleeve 640, realizing the sliding connection between the lifting seat 220 and the base 210, guiding the vertical movement of the lifting seat 220, preventing the lifting seat 220 from shifting, and enabling the multiple rotors 400 connected to the drive mechanism 300 to be stably inserted downward into the abrasive in the grinding barrel 230.

[0041] In some embodiments, the tapered sleeve 610 and the guide sleeve 640 are arranged independently of each other, so that the tapered surface fit of the tapered sleeve 610 and the tapered member 620 does not interfere with the sliding guidance of the guide shaft 630 and the guide sleeve 640.

[0042] In this embodiment, the upper end of the tapered sleeve 610 and the lower end of the guide sleeve 640 are connected, as shown below. Figure 7 As shown, the two are coaxially arranged, and the circumferential diameter of the multiple first screw holes 612 in the laying direction is larger than the diameter of the guide sleeve 640, so that the first fastener and the guide sleeve 640 do not interfere with each other. The tapered member 620 is connected to the lower end of the guide shaft 630, and the two are coaxially arranged.

[0043] Thus, when the lifting seat 220 slides up and down relative to the base 210, the cone sleeve 610 and the cone 620 always correspond vertically, ensuring that when the lifting seat 220 is in the first position, the cone sleeve 610 and the cone 620 cooperate through the cone surface, saving the installation position and installation space of the guide mechanism 600.

[0044] It is understandable that the tapered sleeve 610 and the guide sleeve 640 can be connected by means of screws, bolts or flanges.

[0045] In this embodiment, the tapered sleeve 610 and the guide sleeve 640 are integrally formed, which saves the connection structure between the two, reduces the connection cost, and allows the tapered sleeve 610 and the guide sleeve 640 to be tightly connected.

[0046] It is understandable that, since the output end of the drive unit 310 is connected to multiple workstations 320, the output end of the drive unit 310 needs to bear the weight of multiple workstations 320 and the multiple rotors 400 connected to them, resulting in a large load on the output end of the drive unit 310.

[0047] For this purpose, the lifting seat 220 is rotatably connected to a main shaft sleeve 700. The upper end of the main shaft sleeve 700 is connected to the output end of the drive component 310, and the lower end of the main shaft sleeve 700 is connected to multiple workstations 320 via transmission. Figure 3 As shown, the lifting seat 220 connected to the main sleeve shaft and its rotation bears the weight of multiple workstations 320 and multiple rotors 400, effectively reducing the load on the output end of the drive component 310 and extending the service life of the drive component 310. The main sleeve 700 also bears the rotational motion of the drive component 310, and the rotation of the main sleeve 700 drives the multiple workstations 320 and multiple rotors 400 to rotate.

[0048] In this embodiment, the drive component 310 is an existing motor. The main shaft sleeve 700 is rotatably connected to the lifting seat 220 through two bearings with vertical spacing, so that the main shaft sleeve 700 and the lifting seat 220 are stably connected and can stably bear the weight of multiple workstations 320 and multiple rotors 400.

[0049] It is understood that the drive mechanism 300 also includes a first transmission assembly 330, which includes a first turntable 331, a driving gear 332, and multiple driven gears 333, such as... Figure 2 As shown. Specifically, the lower end of the main shaft sleeve 700 is connected to the first turntable 331 after the drive gear 332 passes through it. The main shaft sleeve 700 is also connected to the drive gear 332. The main shaft sleeve 700, the drive gear 332, and the first turntable 331 are all coaxially arranged, so that the rotating main shaft sleeve 700 drives the drive gear 332 and the first turntable 331 to rotate. Multiple driven gears 333 are rotatably connected to the upper end face of the first turntable 331 through bearings. The multiple driven gears 333 are arranged in a circle with the axis of the drive gear 332 as the array center. The drive gear 332 meshes with the multiple driven gears 333, and each driven gear 333 is connected to multiple workstations 320.

[0050] It is understandable that the drive mechanism 300 also includes multiple second transmission components 340, such as... Figures 2 to 4 As shown, the second transmission assembly 340 is used to realize the transmission connection between each driven gear 333 and multiple workstations 320. The structure of the second transmission assembly 340 is similar to that of the first transmission assembly 330. The second transmission assembly 340 includes a second turntable 341, a first gear 342, and multiple second gears 343, as shown. Figure 4As shown. Specifically, the driven gear 333 is coaxially connected to the second turntable 341 and the first gear 342. When the drive unit 310 is started, the second turntable 341 and the first gear 342 rotate with the driven gear 333. Multiple second gears 343 are rotatably connected to the upper surface of the second turntable 341 via bearings. The multiple second gears 343 are arranged in a circle with the axis of the first gear 342 as the array center. The first gear 342 meshes with the multiple second gears 343, and each second gear 343 corresponds one-to-one with each station 320 and is coaxially connected in the vertical direction. Thus, when the drive unit 310 is started, each station 320 rotates with the connected second gear 343.

[0051] It is understandable that the number of the second transmission assembly 340 and the second gear 343 can be set according to the diameter of the rotor 400 and the spacing between adjacent rotors 400, so that the rotor ultra-precision grinding machine 100 can drive multiple rotors 400 to rotate at one time, thereby improving grinding efficiency.

[0052] In this embodiment, there are four passive gears 333 and four second transmission components 340, four first gears 342 and sixteen second gears 343. Therefore, the rotor ultra-precision grinding machine 100 has sixteen workstations 320, that is, one drive unit 310 can drive sixteen rotors 400 to perform the grinding process simultaneously.

[0053] In some embodiments, the working end 321 and the rotor 400 can be detached by means of snap-fit ​​or other methods, without the need for disassembly tools.

[0054] In this embodiment, the working end 321 is provided with a second threaded hole 322 and a second fastener for threaded connection. The head of the rotor 400 is provided with a connecting groove 420 and a third threaded hole 410, as shown below. Figure 5 As shown, the opening of the connecting groove 420 faces upward, and the third screw hole 410 connects the connecting groove 420 and the arc surface of the rotor 400 head.

[0055] With this configuration, the working end 321 is embedded in the connecting groove 420 of the rotor 400, and the second fastener thread passes through the third screw hole 410 located on the outer side and the second screw hole 322 located on the inner side, so as to achieve a stable connection between the working end 321 and the rotor 400 and avoid the resistance between the rotor 400 and the abrasive from affecting the connection stability between the working end 321 and the rotor 400.

[0056] Understandably, the second fastener can be a screw or a bolt.

[0057] In this embodiment, the workstation 320 is stepped, with the top being larger than the bottom, and the working end 321 is the end with the smaller diameter.

[0058] It is understandable that the rotor 400 includes a connecting surface, and the connecting groove 420 opens to connect the connecting surface. The rotor ultra-precision grinding machine 100 also includes a transition shaft 800, such as... Figure 6 As shown, depending on the head of different rotors 400, it is determined whether a transition shaft 800 is needed.

[0059] It is understandable that the distance between the second screw hole 322 and the end face of the working end 321 is the preset distance.

[0060] In some embodiments, when the distance between the third screw hole 410 and the connecting surface is equal to the preset distance, the working end 321 is directly embedded in the connecting groove 420, and the station 320 and the rotor 400 are rotated relative to each other, so that the second screw hole 322 and the third screw hole 410 are aligned, and the second fastener can be threaded through and fix the station 320 and the rotor 400.

[0061] In another embodiment, when the distance between the third screw hole 410 and the connecting surface is less than the preset distance, the length of the working end 321 embedded in the connecting groove 420 can be adjusted, and the rotating station 320 and the rotor 400 can be rotated relative to each other to align the second screw hole 322 and the third screw hole 410, and the two can be connected by the second fastener.

[0062] In other embodiments, when the distance between the third screw hole 410 and the connecting surface is greater than a preset distance, the second screw hole 322 will never be able to align with the third screw hole 410. In this case, a transition shaft 800 is needed to connect the station 320 and the rotor 400. Specifically, the two ends of the transition shaft 800 are respectively two connecting ends that are fitted and connected to the working end 321 and the rotor 400. The connecting end of the transition shaft 800 connected to the station 320 is provided with a first connecting hole 810, and the connecting end of the transition shaft 800 connected to the rotor 400 is provided with a second connecting hole 822, such as... Figure 6 As shown, there are two second fasteners, which correspond to the first connecting hole 810 and the second connecting hole 822 respectively. The end of the transition shaft 800 with the first connecting hole 810 is sleeved on the working end 321. By rotating and adjusting the relative position of the transition shaft 800 and the working position 320, one of the second fasteners is threaded through the first connecting hole 810 and the second threaded hole 322. The end of the transition shaft 800 with the second connecting hole 822 is embedded in the connecting groove 420. By rotating and adjusting the relative position of the transition shaft 800 and the rotor 400, the other second fastener is threaded through the second connecting hole 822 and the third threaded hole 410.

[0063] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
