For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0041] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0042] The present embodiment relates to an annular workpiece processing device, which can perform oil immersion and rust prevention treatment on the annular workpiece after diameter reduction, thereby improving the oil coating quality and reducing the manual operation cost.

[0043] In terms of overall structure, Figure 1 As shown, the annular workpiece processing device of this embodiment mainly includes a feeding mechanism 2, a diameter reduction mechanism 3, a post-processing mechanism, and a workpiece transfer mechanism 9 which are arranged in sequence. Among them, the workpiece transfer mechanism 9 is used to transfer the annular workpiece between the feeding mechanism 2, the diameter reduction mechanism 3 and the post-processing mechanism. The post-processing mechanism includes an oil immersion mechanism 7, which has an oil immersion tank 701 and an oil immersion basket 710. The oil immersion basket 710 is used to hold the annular workpiece after the diameter reduction, and the oil immersion basket 710 is driven to enter and exit the oil immersion tank 701.

[0044] At this time, the set diameter reduction mechanism 3 can reduce the diameter of the annular workpiece, and the post-processing mechanism can perform oil immersion and rust prevention treatment on the annular workpiece after diameter reduction, and can improve the oil coating quality of the annular workpiece and reduce the manual operation cost.

[0045] It should be noted that the annular workpiece mentioned above is preferably a shaft sleeve 100 in this embodiment. Of course, it can be understood that the annular workpiece can also be other workpieces that need to be reduced in diameter and treated with oil immersion for rust prevention.

[0046] Based on the above overall introduction, for details, continue to refer to Figure 1 As shown, the annular workpiece processing device of this embodiment also includes a frame 1 , and the above-mentioned feeding mechanism 2 , diameter reduction mechanism 3 , post-processing mechanism, and workpiece transfer mechanism 9 are all arranged on the frame 1 .

[0047] Combination Figures 1 to 3 As shown, the feeding mechanism 2 of this embodiment, as a preferred embodiment, comprises a material storage assembly 21 and a material support assembly 22. The material storage assembly 21 comprises a material support tray 212 driven to rotate, and a plurality of vertically arranged material guide rods 213 are provided on the material support tray 212. The plurality of material guide rods 213 are distributed along the circumference of the material support tray 212, and the annular workpieces are stacked and sleeved on the material guide rods 213.

[0048] For specific structure, see Figure 2 As shown, the material tray 212 is circular, and a plurality of guide rods 213 are arranged along the circumference of the material tray 212. In addition, a rotary drive mechanism 211 is provided at the bottom of the material tray 212, and the power output end of the rotary drive mechanism 211 is connected to the material tray 212 to drive the material tray to rotate intermittently. In a specific implementation, the rotary drive mechanism 211 adopts, for example, a rotary disc divider in the prior art. The provision of a plurality of guide rods 213 can facilitate the storage of the annular workpiece, i.e., the sleeve 100, and ensure the smooth progress of the subsequent diameter reduction treatment and oil immersion anti-rust treatment.

[0049] The support assembly 22 is specifically located at one side of the support tray 212. When the support tray 212 rotates until one of its guide rods 213 is located at the support assembly 22, the support assembly 22 can lift the annular workpiece on the guide rod 213 upward, which can facilitate the continuous loading of the annular workpiece and improve the degree of automation of the loading of the annular workpiece. Figure 2 and Figure 3 As shown, the material support assembly 22 includes a lifting drive device arranged on the frame 1, a translation drive device connected to the power output end of the lifting drive device, and a material support fork 221 connected to the power output end of the translation drive device. The material support fork 221 has two fork bodies arranged opposite to each other, and the distance between the two fork bodies is used to avoid the material guide rod 213.

[0050] When the feeding mechanism 2 of this embodiment is used, the two forks are extended toward the corresponding material guide rod 213 under the driving of the translation drive device, so that the two forks are supported on the bottom of the sleeve 100, and then the material support fork 221 is moved upward under the driving of the lifting drive device. At this time, the sleeve 100 on the guide rod 213 is lifted upward to wait for the workpiece transfer mechanism 9 to grab it. After the lifted sleeve 100 is grabbed, the material support fork 221 is retracted away from the material guide rod 213 under the driving of the translation drive device, and then the material support fork 221 is moved downward under the driving of the lifting drive device to load the next sleeve 100.

[0051] It should be noted that the above-mentioned lifting drive device and translation drive device may adopt linear drive devices such as air cylinders, electric cylinders or linear modules in the prior art.

[0052] The reducing mechanism 3 of this embodiment can specifically refer to the mature structure in the prior art. The reducing mechanism 3 includes a plurality of reducing blocks, which can be assembled together, and a reducing groove is formed in the middle of the plurality of reducing blocks after being assembled. The shaft sleeve 100 to be reduced in diameter is transferred to the operating platform of the reducing mechanism 3 through the workpiece transfer mechanism 9, and the shaft sleeve 100 is reduced in diameter through the assembly of the plurality of reducing blocks, so that the reducing groove reduces the shaft sleeve 100.

[0053] The above-mentioned oil immersion mechanism 7 includes an oil immersion tank 701 and an oil immersion basket 710 arranged on the frame 1. The oil immersion basket 710 is used to hold the annular workpiece after the diameter is reduced, and the oil immersion basket 710 is driven to enter and exit the oil immersion tank 701, so that the annular workpiece in the oil immersion basket 710 can be immersed in oil, and after oil immersion, it is also convenient to take out the annular workpiece.

[0054] As a preferred embodiment, in terms of specific structure, Figures 4 to 7As shown, the frame 1 is provided with a first connecting frame 703 which can move in the horizontal direction, the connecting frame is provided with a second connecting frame 704 which can move in the vertical direction, and the oil immersion basket 710 is flippably provided on the second connecting frame 704 .

[0055] In order to facilitate the second connecting frame 704 to move in the vertical direction, a first vertical driving device 706 and a first vertical slide rail are provided on the first connecting frame 703. Corresponding to the first vertical slide rail, a vertical slide rail embedded in the first vertical slide rail is provided on the second connecting frame 704, and the second connecting frame 704 is connected to the power output end of the first vertical driving device 706. At this time, driven by the first vertical driving device 706, the second connecting frame 704 drives the oil immersion basket 710 to move up and down in the vertical direction, thereby facilitating the oil immersion basket 710 to enter and exit the oil immersion tank 701. In addition, when the first connecting frame 703 moves, the oil immersion basket 710 can move in the horizontal direction, and at the same time, the oil immersion basket 710 flips relative to the second connecting frame 704, thereby facilitating the dumping of the annular workpiece in the oil immersion basket 710.

[0056] In order to facilitate the horizontal movement of the first connecting frame 703, in this embodiment, a first transverse driving device 702 and a first transverse slide rail are provided on the frame 1, and corresponding to the first transverse slide rail, a transverse slide rail embedded in the first transverse slide rail is provided on the first connecting frame 703, and the first connecting frame 703 is connected to the power output end of the first transverse driving device 702. Driven by the first transverse driving device 702, the first connecting frame 703 can move in the horizontal direction, so as to facilitate the movement of the oil immersion basket 710 above the oil immersion tank 701 to the side where the oil draining mechanism 8 is located.

[0057] In addition, a rotating rod 7041 is provided on the second connecting frame 704, and the rotating rod 7041 is rotatably provided at one end of the bottom of the oil-immersed material basket 710. In addition, a first flipping drive device 705 is also provided on the second connecting frame 704, and the driving end of the first flipping drive device 705 is hinged to the end away from the rotating rod 7041. At this time, under the drive of the first flipping drive device 705, the oil-immersed material basket 710 can be flipped.

[0058] It is worth noting that, in order to facilitate structural arrangement, the first transverse drive device 702, the first vertical drive device 706 and the first flip drive device 705 in this embodiment preferably adopt oil cylinders or air cylinders.

[0059] As a preferred embodiment, in this embodiment, a plurality of oil leakage holes 7100 are provided on the housing of the oil immersion basket 710. The provision of the leakage holes can prevent the annular workpiece from bringing out a large amount of oil after oil immersion, and facilitates the rapid treatment of the oil on the surface of the annular workpiece. It can be understood that the oil leakage holes 7100 may not be provided on the housing of the oil immersion basket 710. In this case, the oil immersion basket 710 enters and exits the oil immersion tank 701, which will not affect the oil immersion treatment of the annular workpiece. However, when the annular workpiece is taken out, a certain amount of oil will remain in the oil immersion basket 710.

[0060] Continue to view Figures 4 to 7 As shown, in this embodiment, the oil immersion mechanism 7 includes a heating unit 711 for heating the oil in the oil immersion tank 701, and a temperature detection unit for detecting the temperature of the oil. The arrangement of the heating unit 711 and the temperature detection unit can not only heat the oil in the oil immersion tank 701, but also detect the temperature of the oil in real time, thereby facilitating ensuring that the annular workpiece is at a suitable oil immersion temperature. In a specific implementation, the heating unit 711 is preferably a heating tube arranged in the oil immersion tank 701, and the temperature detection unit is preferably a temperature sensor.

[0061] In order to facilitate the detection of the liquid level of the oil in the oil immersion tank 701, in this embodiment, a liquid level detection unit 712 for detecting the liquid level of the oil is provided on the oil immersion tank 701. In specific implementation, the liquid level detection unit 712 preferably adopts a liquid level gauge. In addition, in order to improve the use effect, in this embodiment, a control device is also provided on the frame 1, and the signal lines of the above-mentioned heating tube and temperature sensor are connected to the control device, so that the oil temperature can be adjusted by the control device, thereby also improving the degree of automation. It is worth noting here that the heating tube, temperature sensor and control device can all adopt existing mature products, and the control program in the control device can also be implemented by conventional PLC programming in the prior art.

[0062] As a preferred implementation, in this embodiment, see Figure 8 As shown, the post-processing mechanism also includes an oil draining mechanism 8 disposed downstream of the oil immersion mechanism 7, the oil draining mechanism 8 having a rotatable oil draining barrel 810, and the oil immersion basket 710 is driven to flip so as to dump the contained annular workpiece into the oil draining barrel 810. Since a certain amount of oil is attached to the surface of the annular workpiece after oil immersion, the setting of the oil draining mechanism 8 can facilitate the draining of the oil attached to the surface of the annular workpiece, ensuring the formation of a uniform oil film on the surface of the annular workpiece, thereby improving the oil immersion effect of the annular workpiece.

[0063] For details, see Figure 8As shown, the oil draining mechanism 8 is located on one side of the oil soaking mechanism 7. The oil soaking mechanism 7 includes a frame 801, a rotating drive device and an oil draining barrel 810 arranged on the frame 801. The oil draining barrel 810 is connected to the rotating drive device and is driven to rotate on the frame 801 by the rotating drive device. In addition, the central axis of the oil draining barrel 810 is arranged along the rotation center, and an opening 8101 communicating with the inner cavity of the oil draining barrel 810 is arranged on the side wall of the oil draining barrel 810. When the oil draining barrel 810 rotates to a position corresponding to the oil soaking basket 710, the annular workpiece dumped in the oil soaking basket 710 can enter the cavity in the oil draining barrel 810 through the opening 8101. And the annular workpiece after draining the oil can be poured out to a designated position through the opening 8101.

[0064] As a further improvement of this embodiment, in this embodiment, the oil immersion mechanism 7 also includes a filter unit 713 for filtering the oil in the oil immersion tank 701. Specifically, the filter unit 713 is located below the oil immersion tank 701, and the filter unit preferably adopts a filter pump. In terms of structural setting, an oil discharge port is provided at the bottom of the oil immersion tank 701, and an oil discharge pipe 714 is provided at the oil discharge port to facilitate the discharge of the oil in the oil immersion tank 701. In addition, a three-way interface is also provided on the oil discharge pipe 714, two interfaces of the three-way interface are connected to the oil discharge pipe 714, and the other interface is connected to the oil inlet pipeline 7131 of the filter unit 713. In addition, the oil outlet pipeline 7132 of the filter unit 713 is connected to the oil immersion tank 701, so that the oil filtered by the filter unit 713 flows into the oil immersion tank 701 again through the oil outlet pipeline 7132, thereby filtering the oil in the oil immersion tank 701, which is conducive to ensuring the cleanliness of the oil.

[0065] At the same time, as a preferred embodiment, an oil receiving pan 812 is also provided at the bottom of the oil drain barrel 810, and an oil return pipe 813 is connected to the oil receiving pan 812, and the oil return pipe 813 is connected to the oil inlet pipeline 7131 of the filter unit 713. At this time, the oil receiving pan 812 provided at the bottom of the oil drain barrel 810 can be used to collect the oil drained from the annular workpiece, and the oil return pipe 813 is provided to be connected to the oil inlet pipe of the filter device, so as to filter the oil in the oil pan 812, thereby facilitating the recovery and reuse of the filtered oil.

[0066] As a preferred implementation, in this embodiment, if Figure 1As shown, a detection mechanism 4 is also provided between the diameter reduction mechanism 3 and the post-processing mechanism. The detection mechanism 4 is used to detect the radial dimension of the annular workpiece after diameter reduction. By detecting the radial dimension of the annular workpiece after diameter reduction, the annular workpiece with unqualified radial dimension can be identified in time. In specific implementation, the detection mechanism 4 includes a detection table and an outer diameter detector provided on the frame 1. The annular workpiece after diameter reduction is transferred to the detection table by the workpiece transfer mechanism 9, and the radial dimension of the annular workpiece is detected by the outer diameter detector, wherein the outer diameter detector can adopt, for example, a digital micrometer or an outer diameter laser detector in the prior art.

[0067] Based on the setting of the detection mechanism 4, in order to facilitate the separation of annular workpieces with qualified radial dimensions and those with unqualified radial dimensions. In this embodiment, as a preferred embodiment, Figure 1 Combined with Figure 5 , Figure 7 As shown, a transfer mechanism 6 and a material discharge mechanism 5 are also provided between the detection mechanism 4 and the post-processing mechanism. The material discharge mechanism 5 has a material discharge basket 503, which is used to collect annular workpieces with unqualified radial dimensions, and the transfer mechanism 6 has a transfer basket 610, which is used to collect annular workpieces with qualified radial dimensions. At this time, the provided transfer mechanism 6 and material discharge mechanism 5 can facilitate the separation of annular workpieces with qualified radial dimensions and those with unqualified radial dimensions.

[0068] Specifically, Figure 5 and Figure 7 As shown, the unloading mechanism 5 includes an unloading port 501 located at one side of the detection mechanism 4, and an unloading channel 502 connected to the unloading port 501, and a unloading basket 503 is specifically located at one end of the unloading channel 502 away from the unloading port 501. After the detection mechanism 4 detects an annular workpiece with unqualified radial dimensions, the annular workpiece with unqualified radial dimensions will be transferred to the unloading port 501, and transported to the unloading basket 503 through the unloading channel 502.

[0069] In this embodiment, the transfer basket 610 is driven to move toward the oil immersion tank 701, and can be turned over to dump the collected annular workpieces into the oil immersion basket 710. By moving and turning the transfer basket 610, it is convenient to dump the collected annular workpieces into the oil immersion basket 710, so that multiple annular workpieces can be immersed in oil, which is conducive to improving the oil immersion efficiency.

[0070] For specific structure, see Figure 5 and Figure 7As shown, as a preference, the transfer mechanism 6 of this embodiment includes a mounting plate 613 slidably mounted on the frame 1, and a transfer material basket 610 flipped on the mounting plate 613. In order to facilitate the transfer material basket 610 to move toward the oil immersion tank 701, in this embodiment, a first linear drive device 611 and a first slide rail are provided on the frame 1. Among them, the length direction of the first slide rail is arranged along the direction pointing to the oil immersion tank 701. Corresponding to the first slide rail, a first slideway that is embedded and matched with the first slide rail is provided on the mounting plate 613, and the mounting plate 613 is connected to the power output end of the first linear drive device 611. Driven by the first linear drive device 611, the mounting plate 613 can move along the first slide rail toward the oil immersion tank 701, thereby driving the transfer material basket 610 to move toward the oil immersion tank 701.

[0071] In addition, one end of the bottom of the transfer basket 610 is rotatably connected to the mounting plate 613 via a rotating shaft 614, and a second flipping drive device 612 is also provided on the frame 1, and the power output end of the second flipping drive device 612 is connected to the end of the transfer basket 610 away from the rotating shaft 614, so that under the pushing drive of the second flipping drive device 612, the transfer basket 610 can be flipped toward the top of the oil immersion tank 701 to dump the annular workpiece in the transfer basket 610 into the oil immersion basket 710.

[0072] It should be noted that the first linear drive device 611 and the second flip drive device 612 preferably adopt air cylinders or oil cylinders to facilitate structural arrangement.

[0073] As a further preferred embodiment, in this embodiment, the workpiece transfer mechanism 9 includes a lateral moving component and a plurality of gripping units 903 arranged on the lateral moving component. The lateral moving component can drive the plurality of gripping units 903 to move between the first station and the second station, and the plurality of gripping units 903 are arranged in a one-to-one correspondence with the feeding mechanism 2, the diameter reduction mechanism 3 and the detection mechanism 4 at the first station, and the plurality of gripping units 903 are arranged in a one-to-one correspondence with the diameter reduction mechanism 3, the detection mechanism 4 and the transfer mechanism 6 at the second station.

[0074] At this time, by moving the lateral moving component between the first station and the second station, multiple grabbing units 903 can be driven to move synchronously, so that the annular workpieces on the feeding mechanism 2, the reducing mechanism 3 and the detection mechanism 4 can be moved synchronously, which can improve the structural integration and also help shorten the production cycle.

[0075] See also Figure 8 , Fig. 9 , and combined with Figure 1As shown, in this embodiment, the lateral movement assembly includes a translation plate 901 that is arranged on the frame 1 and moves in the horizontal direction, and multiple grabbing units 903 can be raised and lowered on the translation plate 901. Specifically, a second lateral movement device 900 and a second lateral slide rail are provided on the frame 1. The translation plate 901 is provided with a slideway that is embedded and matched with the second lateral slide rail, and the translation plate 901 is connected to the power output end of the second lateral movement device 900, so that the translation plate 901 can move between the first station and the second station in the horizontal direction under the drive of the second lateral movement device 900, thereby driving the multiple grabbing units 903 to move between the first station and the second station.

[0076] In addition, see Figure 8 and Fig. 9 As shown, the translation plate 901 is also provided with a plurality of second vertical drive devices 902 corresponding to each grabbing unit 903, and the plurality of second vertical drive devices 902 correspond to the plurality of grabbing units 903 one by one, and each grabbing unit 903 is correspondingly connected to the power output end of each second vertical drive device 902. In terms of specific structure, each grabbing unit 903 includes two clamping blocks 9031 that can approach or move away from each other, and each clamping block 9031 has a clamping end face that is roughly V-shaped. By the two clamping blocks 9031 approaching each other, the outer peripheral surface of the annular workpiece can be clamped.

[0077] In order to facilitate a clearer understanding of this solution, along the direction from the feeding mechanism 2 to the detection mechanism 4, the grabbing units 903 are defined as the first grabbing unit 903, the second grabbing unit 903 and the third grabbing unit 903. Driven by the second vertical driving device 902 and the second lateral moving device 900, the first grabbing unit 903, the second grabbing unit 903 and the third grabbing unit 903 can move synchronously, and when the translation plate 901 moves from the first station to the second station, the first grabbing unit 903 transfers the clamped annular workpiece from the feeding mechanism 2 to the diameter reduction mechanism 3, the second grabbing unit 903 transfers the annular workpiece after diameter reduction from the diameter reduction mechanism 3 to the detection mechanism 4, and the third grabbing unit 903 transfers the annular workpiece after detection from the detection mechanism 4 to the transfer mechanism 6. In this way, the smooth flow of the annular workpiece between the various mechanisms can be achieved, and the compactness of the structure can be improved while shortening the production cycle.

[0078] It is worth noting that in this embodiment, the second lateral drive device preferably adopts the driving form of the servo motor and the lead screw in the prior art, which can improve the movement accuracy of the grabbing unit 903. Of course, it is understandable that it can also adopt a linear drive device such as a cylinder, an oil cylinder or a linear module.

[0079] The annular workpiece processing device of this embodiment loads the annular workpiece to be reduced in diameter to the specified position through the loading mechanism 2, and then uses the workpiece transfer mechanism 9 to transfer the annular workpiece to the reduction mechanism 3 for reduction processing. After the reduction is completed, the workpiece moving mechanism transfers the reduced annular workpiece to the detection mechanism 4. The detection mechanism 4 detects the outer diameter size of the annular workpiece after reduction. The annular workpieces with unqualified outer diameter sizes are removed to the discharge port 501 and collected in the discharge basket 503 through the discharge channel 502. The annular workpieces with qualified outer diameter sizes are continued to be transferred from the detection mechanism 4 to the transfer basket 610 of the transfer mechanism 6 by the workpiece transfer mechanism 9.

[0080] When a certain number of annular workpieces are collected in the transfer basket 610, the transfer basket 610 is moved to one side of the oil immersion tank 701 by the driving of the first linear drive device 611, and is flipped by the lifting of the second flipping drive device 612. At this time, the annular workpieces contained in the transfer basket 610 are dumped into the oil immersion basket 710.

[0081] Then, the annular workpiece in the oil-immersed basket 710 is immersed in the oil by the first vertical driving device 706. After a certain period of immersion, the oil-immersed basket 710 is moved to the top of the oil-immersed tank 701 by the first vertical driving device 706, and the oil-immersed basket 710 is moved to the oil-draining barrel 810 by the first horizontal driving device 702. Then, the oil-immersed basket 710 is turned over by the first flipping driving device 705 at a certain angle, so that the annular workpiece in the oil-immersed basket 710 is dumped into the oil-draining barrel 810. Through the rotation of the oil-draining barrel 810, the oil attached to the outer surface of the annular workpiece is quickly separated into the oil receiving pan 812, and a uniform oil film is formed on the outer surface of the annular workpiece. The annular workpiece processing device of this embodiment can perform oil-immersion anti-rust treatment on the annular workpiece with a reduced diameter, and has a good oil-immersion effect, improves the oil coating quality of the annular workpiece, reduces the cost of manual operation, and can also improve the degree of automation of the equipment, and has a good use effect.

[0082] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
