Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile brake disc manufacturing, and particularly relates to a turning-over tool for automobile brake disc. BACKGROUND

[0002] The brake disc, also called the brake disc, is usually made of low-chromium gray cast iron by hot pressing forming, and the forming route is roughly as follows: preparation of mixed pressing material, pre-forming, hot pressing forming, shaping and polishing, heat treatment, mechanical processing, assembly, and packaging. The mechanical processing procedure includes edge rounding processing, surface thread blind hole processing, and installation groove milling forming processing, etc.

[0003] Taking the surface thread blind hole forming as an example, two drilling machines are needed to perform drilling and tapping processing on the front and back surfaces respectively at the same station or adjacent stations. In this process, the turning-over operation of the automobile brake disc needs to be performed by the operator, and the overall time for single piece processing is relatively long (about 5 minutes), which is embodied in the following two aspects: 1) a large amount of manpower and material resources are consumed for unlocking, repositioning, and locking operation of the automobile brake disc, and the whole operation process is time-consuming and laborious; 2) the relative position accuracy of the automobile brake disc after re-clamping is difficult to guarantee, and a large amount of time is consumed for adjusting the processing posture of the drilling machine to ensure that the drilling and tapping integrated drill bit can be accurately aligned with the drilling reference line, so that the above problems need to be solved by technical personnel.

[0004] Therefore, the designers of the present application, in view of the above existing problems and defects, collected relevant data, made various evaluations and considerations, and through the continuous experiments and modifications of the technical personnel engaged in this industry for many years, finally led to the appearance of the turning-over tool for automobile brake disc.

[0005] In order to solve the above technical problems, the application relates to a car brake disc turning-over tool matched with a low-degree-of-freedom manipulator, which comprises a base plate, a turning-over mechanism and a linear conveying mechanism. The turning-over mechanism comprises a support frame, a turning-over flat plate, a turning-over tray and a rotating power unit. The support frame is fixed on the base plate. The turning-over flat plate is carried by the support frame and performs circumferential rotation under the driving force of the rotating power unit. The turning-over tray is detachably fixed on the turning-over flat plate to receive the car brake disc to be processed transferred by the low-degree-of-freedom manipulator. The linear conveying mechanism is used to transfer the car brake disc from a previous processing station to a subsequent processing station and is matched with the turning-over mechanism and comprises a sliding platform assembly, a linear power unit and a sliding rail and sliding block assembly. The sliding platform assembly is used to receive the car brake disc processed in the previous processing station and is arranged above the base plate and performs directional translation under the cooperation of the linear power unit and the sliding rail and sliding block assembly. Before the car brake disc is processed in the previous processing station, the turning-over flat plate is always kept in a horizontal state and the turning-over tray on the turning-over flat plate faces upward, and at this time, the low-degree-of-freedom manipulator is actuated to place the car brake disc to be processed in position relative to the turning-over tray. After the car brake disc is processed in the previous processing station, the linear power unit is actuated to drive the sliding platform assembly to move from the subsequent processing station to the previous processing station. After the sliding platform assembly is stopped in position relative to the previous processing station, the rotating power unit is actuated to drive the turning-over flat plate to rotate circumferentially by 180 degrees, and then the car brake disc processed in the previous processing station falls from the turning-over tray to the sliding platform assembly under the action of gravity, and then the linear power unit is actuated again to drive the sliding platform assembly to perform directional translation until the subsequent processing station to process the car brake disc in the subsequent processing station.

[0006] As a further improvement of the technical scheme of the application, the support frame is detachably fixed on the base plate and comprises first and second support plates arranged opposite to each other. The rotating power unit comprises first and second rotating shaft assemblies and a direct-drive motor. The first and second rotating shaft assemblies are respectively and one-to-one assembled on the first and second support plates and cooperatively support the turning-over flat plate. The direct-drive motor outputs a rotating torque to the first or second rotating shaft assembly.

[0007] As a further improvement of the technical scheme of the present application, the rotating power part further comprises a first limiting unit. The first limiting unit is used to limit the final rotating angle of the turnover flat plate, and comprises a rotating limiting member and a first oil pressure buffer. The rotating limiting member is sleeved on the first rotating shaft assembly and performs a synchronous circumferential rotating movement with the first rotating shaft assembly. A limiting arm extends outward from the circumferential side wall of the rotating limiting member. The first oil pressure buffer is detachably fixed on the first supporting plate and is located opposite to the limiting arm. In the process of the circumferential rotating movement of the turnover flat plate, when the limiting arm elastically abuts against the first oil pressure buffer, the turnover flat plate is completely parallel to the sliding platform assembly.

[0008] As a further improvement of the technical scheme of the present application, the linear power part is preferably a rodless cylinder or a linear module which is detachably fixed on the base plate.

[0009] As a further improvement of the technical scheme of the present application, the sliding platform assembly comprises a translating base plate, a supporting base plate, a translating material supporting disc and a pushing power part. The translating base plate is directly driven by the linear power part. The supporting base plate is arranged directly above the translating base plate and performs a displacement movement towards / away from the translating base plate under the action of the pushing power part. The translating material supporting disc is detachably fixed on the supporting base plate. When the linear power part is started and the translating material supporting disc is aligned with the turnover material supporting disc, the turnover material supporting disc releases the fixation of the automobile brake disc which has undergone the previous treatment so that the automobile brake disc is freely placed on the translating material supporting disc.

[0010] As a further improvement of the technical scheme of the present application, the sliding platform assembly further comprises a guiding unit. The guiding unit is composed of a left guiding subunit and a right guiding subunit. The left guiding subunit and the right guiding subunit have the same design structure and cooperatively perform a directional displacement movement of the supporting base plate relative to the translating base plate. Only for the left guiding subunit, it comprises a first guiding shaft, a first guiding sleeve, a second guiding shaft and a second guiding sleeve. The first guiding sleeve and the second guiding sleeve are embedded in the translating base plate, and the upper free end of the first guiding shaft matched with the first guiding sleeve and the upper free end of the second guiding shaft matched with the second guiding sleeve are vertically inserted into the supporting base plate.

[0011] As a further improvement of the technical scheme of the present application, the sliding platform assembly comprises a second limiting unit. The second limiting unit comprises a connecting transition plate, a first limiting stud and a second oil pressure buffer. The connecting transition plate is connected to the first guiding shaft and the second guiding shaft and performs a synchronous displacement movement with the first guiding shaft and the second guiding shaft. The first limiting stud and the second oil pressure buffer are both inserted into the connecting transition plate, are arranged side by side and cooperatively limit the lowest limit position of the supporting base plate.

[0012] As a further improvement of the technical scheme of the present application, the automobile brake disc turnover tooling comprises a third limiting unit. The third limiting unit is composed of a front third limiting sub-unit and a rear third limiting sub-unit. The front third limiting sub-unit and the rear third limiting sub-unit are both fixed on the base plate to respectively and one-to-one correspondingly limit the frontmost limit position and the last limit position of the sliding platform assembly.

[0013] As a further improvement of the technical scheme of the present application, the front third limiting sub-unit and the rear third limiting sub-unit have the same design structure. Only for the front third limiting sub-unit, it comprises a front limiting support and a third oil pressure buffer. The front limiting support is detachably fixed on the base plate. The third oil pressure buffer is horizontally placed and inserted into the front limiting support. When the linear power part is started, the sliding platform assembly performs directional translation movement along the front-rear direction until the side wall thereof abuts against the third oil pressure buffer, at which time, the translation material supporting disc is kept in the opposite position relative to the turnover material supporting disc.

[0014] In the specific application of the automobile brake disc turnover tooling, taking the machining of the surface threaded blind hole of the automobile brake disc as an example, before the front threaded blind hole of the automobile brake disc is machined, the turnover material supporting disc is kept in a horizontal state, at which time, the front surface of the automobile brake disc placed and fixed in position is beneficial to the machining and forming of the front threaded blind hole; after the front threaded blind hole is machined and formed, the sliding platform assembly is displaced from the rear processing station to the front processing station under the driving force of the linear power part to receive the automobile brake disc transferred through the turnover material supporting disc (when the automobile brake disc is settled relative to the turnover material supporting disc, the back surface thereof faces upward), and then, the sliding platform assembly carrying the automobile brake disc is displaced to the rear processing station until it is accurately positioned with the rear drilling machine to provide a good foundation for the machining and forming of the back threaded blind hole.

[0015] In actual application, the automobile brake disc turnover tooling at least has the following beneficial technical effects, specifically:

[0016] 1) The posture of the automobile brake disc is turned over by the turnover mechanism, and the automobile brake disc is transferred from the front processing station to the rear processing station by the linear conveying mechanism, so that the whole operation process is very fast and quick;

[0017] 2) During the whole machining process of the automobile brake disc, it is beneficial to accurately position the automobile brake disc relative to the front drilling machine and the rear drilling machine, thereby ensuring that the machined threaded blind hole has very high position accuracy;

[0018] 3) In the whole process of turning over and position changing of the automobile brake disc, no worker is needed to assist, and a large number of working hours consumed for unlocking and repositioning and clamping are saved, not only a large amount of manpower and material resources are liberated, but also the processing time of the automobile brake disc is greatly reduced (for example, the processing time is shortened from 5 minutes to 3 minutes for the processing of the threaded blind hole).

DETAILED DESCRIPTION

[0036] In the description of the present application, it should be understood that the terms "front", "back", "upper", "lower", "left", "right" and the like indicate the orientation or positional relationship shown in the drawings based on the orientation or positional relationship, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0037] The content of the present application will be further described in detail below in conjunction with specific embodiments, such as Figure 1 As shown in the drawings, the automobile brake disc is in a disc-shaped structure, which is the most critical component in the automobile braking system, and is applied in cooperation with the brake caliper to realize the instantaneous braking of the vehicle.​​​

[0038] Figure 2 The schematic view of the arrangement position of the automobile brake disc turnover tool in the application relative to the low degree of freedom manipulator is shown, and it can be seen that the automobile brake disc turnover tool is arranged on one side of the low degree of freedom manipulator, so as to receive the automobile brake disc whose surface has undergone polishing and shaping treatment via the low degree of freedom manipulator, so as to lay a foundation for subsequent machining operations (including edge rounding machining, surface thread blind hole machining and installation groove milling forming machining and other steps).

[0039] Figure 3 The schematic view of the first embodiment of the automobile brake disc turnover tool in the application is shown, and it can be seen that it is mainly composed of a base plate 1, a turnover mechanism 2 and a linear conveying mechanism 3. As shown in Figure 4 The turnover mechanism 2 includes a support frame 21, a turnover flat plate 22, a turnover material supporting disc 23 and a rotary power part 24. The support frame 21 is fixed on the base plate 1. The turnover flat plate 22 is carried and borne by the support frame 21 and performs circumferential rotation motion under the driving force of the rotary power part 24. The turnover material supporting disc 23 is detachably fixed on the turnover flat plate 22 by screws, so as to receive the automobile brake disc to be processed via the low degree of freedom manipulator. A first accommodating groove compatible with the shape of the automobile brake disc is formed on the turnover material supporting disc 23. Figure 4 As shown in the figure, it can also be clearly seen that the turnover material supporting disc 23 is simultaneously matched with a first vacuum suction nozzle assembly and a first gas supply connector. The first vacuum suction nozzle assembly is composed of a plurality of first vacuum suction nozzles inserted into the first accommodating groove and cooperates to realize / dissolve the suction operation of the automobile brake disc. After the first vacuum suction nozzle is assembled in place relative to the turnover material supporting disc 23, the top wall is preferably flush with the bottom wall of the first accommodating groove. The first gas supply connector is inserted into the side wall of the turnover material supporting disc 23, so as to simultaneously provide negative pressure support for each first vacuum suction nozzle. As shown in Figure 9 The linear conveying mechanism 3 is used to transfer the automobile brake disc from the previous processing station to the subsequent processing station, which is matched with the turnover mechanism 2 and includes a sliding platform assembly 31, a rodless cylinder 32 and a sliding rail sliding block assembly 33. The sliding platform assembly 31 is used to receive the automobile brake disc which has undergone previous processing via the turnover mechanism 2, and is arranged directly above the base plate 1. The sliding platform assembly 31 performs directional translation motion under the cooperation of the rodless cylinder 32 and the sliding rail sliding block assembly 33, so as to circulate between the previous processing station and the subsequent processing station.

[0040] Before the formal processing operation of the automobile brake disc is performed at the front processing station, the turnover plate 22 is always kept in a horizontal state, and the turnover material supporting plate 23 thereon is front-up, then the low-degree-of-freedom manipulator is actuated to place the automobile brake disc to be processed in position relative to the turnover material supporting plate 23, then each first vacuum suction nozzle is supported by negative pressure to reliably adsorb the automobile brake disc, which means that the automobile brake disc is effectively clamped. In this state, the front drill press that keeps alignment with the automobile brake disc is actuated to form a threaded blind hole on the front face of the automobile brake disc. After the front threaded blind hole is processed, the rodless cylinder 32 is started to drive the sliding platform assembly 31 to displace from the rear processing station to the front processing station. After the sliding platform assembly 31 is stopped in position relative to the front processing station, the rotary power part 24 is started to drive the turnover plate 22 to rotate 180° in the circumferential direction, at this time, the front face of the automobile brake disc is downward, and keeps alignment with the sliding platform assembly 31, then each first vacuum suction nozzle loses the negative pressure support at the same time, thereby causing the automobile brake disc processed by the front process to fall from the turnover material supporting plate 23 to the sliding platform assembly 31 under the action of its own gravity, and then the rodless cylinder 32 is started again to drive the sliding platform assembly 31 to perform directional displacement motion until the rear processing station, so as to realize accurate alignment of the automobile brake disc with the rear drill press, to well pave the way for processing and forming of the back threaded blind hole.

[0041] By adopting the above technical scheme, in the process of performing threaded blind hole processing operation on the automobile brake disc, the process of turning over and changing the position of the automobile brake disc does not need the assistance of workers, thereby saving a large amount of working hours consumed for unlocking and repositioning and clamping. In this way, not only a large amount of manpower and material resources are liberated, but also the threaded blind hole processing time of the automobile brake disc is greatly reduced (the processing time is shortened from 5 minutes to 3 minutes). In addition, in the process of machining the automobile brake disc, the posture of the automobile brake disc can be quickly and rapidly turned over by the turnover mechanism 2, and the automobile brake disc can be transferred from the front processing station to the rear processing station by the linear conveying mechanism 3. The automobile brake disc before and after turning over has good alignment accuracy relative to the front processing station and the rear processing station respectively, and finally ensures that the formed threaded blind hole has excellent position accuracy.

[0042] As a further refinement of the above-mentioned automobile brake disc turnover tool structure, as shown in Figure 4 , the support frame 21 is preferably composed of oppositely arranged first and second support plates 211 and 212. The first and second support plates 211 and 212 are detachably fixed to the base plate 1 by screws. Figure 5 , 6As shown in the figure, the rotating power part 24 is preferably composed of a first rotating shaft assembly 241, a second rotating shaft assembly 242 and a direct drive motor 243. The first rotating shaft assembly 241 and the second rotating shaft assembly 242 are respectively and correspondingly transversely arranged on the first support plate 211 and the second support plate 212, and work together to support and bear the overturning flat plate 22. The direct drive motor 243 outputs a rotating torque to the first rotating shaft assembly 241, and in the process of driving the first rotating shaft assembly 241, the overturning flat plate 22 performs a synchronous circumferential rotation motion.

[0043] Furthermore, as shown in the figure, Figure 7 As shown in the figure, the rotating power part 24 is additionally provided with a first limiting unit 244 for limiting the final rotation angle of the overturning flat plate 22. The first limiting unit 244 includes a rotating limiting piece 2441 and a first oil pressure buffer 2442. The rotating limiting piece 2441 is directly sleeved on the first rotating shaft assembly 241 and performs a circumferential rotation motion synchronously with the first rotating shaft assembly 241. As shown in the figure, Figure 8 The rotating limiting piece 2441 has a limiting arm 24411 extending outward from the circumferential side wall. The first oil pressure buffer 2442 is vertically inserted into the top wall of the first support plate 211 and is opposite to the limiting arm 24411. By adopting the above technical solution, on the one hand, when the limiting arm 24411 elastically abuts against the first oil pressure buffer 2442 in the process of the circumferential rotation of the overturning flat plate 22, the overturning flat plate 22 is kept in a completely horizontal state, which helps to ensure that the overturning flat plate 22 is kept parallel to the sliding platform assembly 31, and finally ensures that the automobile brake disc is smoothly and accurately transferred from the overturning material supporting disc 23 to the sliding platform assembly 31. On the other hand, when the rotation angle of the overturning flat plate 22 deviates slightly, the operator can adjust the working stroke of the first oil pressure buffer 2442, thereby directly realizing the accurate limitation of the final rotation angle of the limiting arm 24411. The whole operation process is fast and quick.

[0044] As shown in the figure, Figure 10 , 11It can also be clearly seen in the figure that the sliding platform assembly 31 is preferably composed of a translation base plate 311, a supporting top base plate 312, a translation supporting tray 313, and a pushing top cylinder 314. The translation base plate 311 is directly driven by the above-mentioned rodless cylinder 32. The supporting top base plate 312 is arranged directly above the translation base plate 311 and performs displacement movement towards / away from the translation base plate 311 under the pushing force of the pushing top cylinder 314. The translation supporting tray 313 is detachably fixed to the supporting top base plate 312 and has a second accommodating groove with a shape matching that of the automobile brake disc arranged therein. In this way, after the front surface of the automobile brake disc is processed with the threaded blind hole, the rotary power part 24 is started to drive the turnover supporting tray 23 to perform 180° circumferential rotation movement. In this case, the automobile brake disc is lowered with the front surface facing downward, and at the same time, the pushing top cylinder 314 is actuated to lower the position height of the translation supporting tray 313 to avoid rigid impact with the turnover plate 22 or the turnover supporting tray 23 in the subsequent displacement process. Then, the rodless cylinder 32 is started to drive the translation supporting tray 313 to perform displacement movement until the previous processing station, and then the pushing top cylinder 314 is started again to raise the position height of the translation supporting tray 313 until it is at a proper distance from the translation supporting tray 313, ensuring that the automobile brake disc can be accurately and quickly placed in the second accommodating groove from the first accommodating groove for subsequent reverse threaded blind hole processing.

[0045] In the specific operation state of the rear drilling machine, in order to simultaneously take into account the good position stability of the positioned automobile brake disc, avoid the position change of the automobile brake disc due to the machining force, and thus affect the position accuracy of the formed threaded blind hole, and as much as possible improve the positioning and clamping efficiency of the automobile brake disc, referring to the design structure of the turnover supporting tray 23, the translation supporting tray 313 can be simultaneously matched with a second vacuum nozzle assembly and a second gas supply connector. Specifically as Figure 10 As shown in the figure, the second vacuum nozzle assembly is composed of a plurality of second vacuum nozzles inserted into the second accommodating groove and cooperated with each other to realize / release the adsorption operation of the automobile brake disc. After the second vacuum nozzles are assembled in place relative to the translation supporting tray 313, the top wall thereof is preferably flush with the bottom wall of the second accommodating groove. The second gas supply connector is inserted into the side wall of the translation supporting tray 313 to simultaneously provide negative pressure support for each second vacuum nozzle. When the automobile brake disc is placed in place relative to the second accommodating groove, the second vacuum nozzles are simultaneously started to reliably adsorb the front surface of the automobile brake disc to resist the mechanical machining force generated in the drilling and tapping process.

[0046] Furthermore, as Figures 10 to 13As shown, the sliding platform assembly 31 is further provided with a guide unit 315. The guide unit 315 consists of a left guide subunit 3151 and a right guide subunit 3152. The left guide subunit 3151 and the right guide subunit 3152 have the same design structure, differing only in their arrangement, and work together to enable the support plate 312 to perform directional displacement relative to the translation plate 311. The left guide subunit 3151 includes a first guide shaft 31511, a first guide sleeve 31512, a second guide shaft 31513, and a second guide sleeve 31514. The first guide sleeve 31512 and the second guide sleeve 31514 are both embedded and inserted into the translation plate 311, while the upper free end of the first guide shaft 31511, which is adapted to the first guide sleeve 31512, and the upper free end of the second guide shaft 31513, which is adapted to the second guide sleeve 31514, are both vertically inserted into the support plate 312. By adopting the above technical solution, during the process of the push cylinder 314 being activated, the translational support plate 313 always performs directional displacement movement in the vertical direction, ensuring that it always remains in a horizontal state. This facilitates the translational support plate 313 maintaining a parallel state with the flipping support plate 23 during the stage of receiving the car brake disc.

[0047] Furthermore, by Figures 10 to 13 As shown, the sliding platform assembly 31 is further provided with a second limiting unit 316. The second limiting unit 316 mainly consists of a connecting transition plate 3161, a first limiting stud 3162, and a second hydraulic buffer 3163. The connecting transition plate 3161 is connected to the first guide shaft 31511 and the second guide shaft 31513, and performs synchronous displacement movement with the first guide shaft 31511 and the second guide shaft 31513. The first limiting stud 3162 and the second hydraulic buffer 3163 are both inserted into and fixed to the connecting transition plate 3161, arranged side by side, and work together to limit the lowest limit position of the support plate 312. During the process of limiting the limit position of the support plate 312, the second hydraulic buffer 3163 acts first to apply an elastic pushing force to the support plate 312, while the first limiting stud 3162 plays a rigid limiting role at the end of the displacement of the support plate 312.

[0048] In addition, to effectively limit the foremost and last extreme positions of the sliding platform component 31, and to ensure that it can accurately stop at the upstream and downstream processing stations in specific applications, such as... Figure 3As shown in the figure, the automobile brake disc turnover tool is also provided with a third limiting unit 4. The third limiting unit 4 is composed of a front third limiting sub-unit 41 and a rear third limiting sub-unit. The front third limiting sub-unit 41 and the rear third limiting sub-unit are both fixed on the base plate 1 and are apart from each other by a certain distance along the front-rear direction. The front third limiting sub-unit 41 and the rear third limiting sub-unit have the same design structure. As shown in the figure, Figure 14 As shown in the figure, the front third limiting sub-unit 41 comprises a front limiting support 411 and a third oil pressure buffer 412. The front limiting support 411 is detachably fixed on the base plate 1 by means of screws. The third oil pressure buffer 412, which can rigidly abut against the translation base plate 311, is placed horizontally and is inserted into the front limiting support 411. When the rodless cylinder 32 is removed, the sliding platform assembly 31 performs directional translation movement along the front-rear direction until the side wall thereof abuts against the third oil pressure buffer 412, at which time the translation material supporting disc 313 is kept in the opposite position relative to the turnover material supporting disc 23.

[0049] Figure 15 As shown in the figure, the automobile brake disc turnover tool of the second embodiment of the present application is shown in a perspective view. Compared with the first embodiment, the difference lies in that a protective cover 5 is additionally arranged around the linear conveying mechanism 3 and is detachably connected to the base plate 1 by means of screws. In this way, the probability of the operator being injured by the high-speed linear conveying mechanism 3 due to misoperation can be effectively reduced.

[0050] Finally, it should be noted that the above description takes the machining of the threaded blind hole of the automobile brake disc as an example for illustration. Of course, the automobile brake disc turnover tool can also be applied to machining scenes such as edge rounding, installation groove milling forming, etc. according to different machining purposes.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
