Detailed implementation manners

[0036] The present invention will be described in detail below in conjunction with specific embodiments.

[0037] A wheel flipping machine of the present invention is mainly used for flipping operations of wheel assemblies such as wheels and wheel brake discs of bullet trains and train vehicles, so as to meet the processing, detection, and maintenance requirements for different surfaces during the above-mentioned operations. The device has a compact structure, is convenient to control and use, has few drive structures, can be very conveniently combined with an electric control system to achieve automation, and a single person can complete the flipping of the wheel and reach any surface area.

[0038] As Figure 1 shown, the main structure of the wheel flipping machine of the present invention includes a bottom support assembly 1, a lifting support assembly 2, a clamping and flipping assembly 3, a wheel rotating assembly 4, and a horizontal drive assembly 5;

[0039] The bottom support assembly is used to form a basic support and guiding structure, which is used to realize the guiding and support of the clamping structures on the left and right sides, so as to ensure that the wheel can be symmetrically clamped and positioned from the left and right sides. At the same time, the bottom forms an installation space for the drive system, so that the center of mass of the entire device sinks, ensuring the stability of the device itself during the operation of large-mass wheels, reducing the total mass of the moving parts, and thus reducing energy consumption.

[0040] As Figure 1 , Figure 2 shown, the bottom support assembly 1 includes: chassis 10, lateral guide rail 11, horizontal sliding plate frame 12, and intermediate fixed plate frame 13;

[0041] The middle fixed plate frame 13 is fixedly arranged in the middle of the bottom frame 10. Two groups of transverse guide rails 11 are symmetrically arranged on the left and right sides of the middle fixed plate frame 13. Two horizontal sliding plate frames 12 are movably connected to the transverse guide rails 11 through sliders.

[0042] To ensure stable support and the action consistency of the action mechanisms on both left and right sides, in specific implementation, each group of transverse guide rails 11 includes at least two horizontal linear guide rails arranged in parallel and along the left-right direction, and the tops of the horizontal linear guide rails are flush.

[0043] The lifting support assembly 2 includes: a vertical frame 20, a vertical lead screw 21, and a vertical guide rail 22.

[0044] Two vertical frames 20 are fixedly arranged on the upper sides of the two horizontal sliding plate frames 12. The vertical lead screw 21 is vertically installed inside the vertical frame 20. Two groups of vertical guide rails 22 are arranged on one side of the two vertical frames 20 facing the middle fixed plate frame 13 and are arranged vertically.

[0045] Two lifting support assemblies 2 are symmetrically arranged on the bottom support assembly 1 through linear guide rails. By controlling the positions of the two vertical frames 20, the symmetrical clamping operation on the left and right sides can be conveniently achieved. The structure is simple and efficient, and has high stability.

[0046] As Figure 3 、 Figure 4 shown, two clamping and flipping assemblies 3 are respectively installed on the two vertical frames 20. The clamping and flipping assembly 3 includes: a vertical sliding plate frame 30, an electric turntable 31, a clamping arm 32, and a clamping wheel 33.

[0047] The vertical sliding plate frame 30 is connected to the vertical guide rail 22 through a slider. A first nut seat 300 is arranged on the outer plate surface of the vertical sliding plate frame 30, and the first nut seat 300 is sleeved on the vertical lead screw 21. The electric turntable 31 is arranged on the inner plate surface of the vertical sliding plate frame 30, and its rotating shaft horizontally points to one side of the middle fixed plate frame 13. The clamping arm 32 is fixed on the rotating disk surface of the electric turntable 31. The clamping arm 32 has a Y-shaped structure. Two clamping wheels 33 are respectively installed on the bifurcations at the ends of the clamping arm 32, and an annular positioning groove 33a is arranged in the middle of the clamping wheel 33.

[0048] The electric turntable 31 includes a support disk 300 fixed on the vertical sliding plate frame 30 and a movable disk 301 connected to the support disk 300 through a rotating bearing. The clamping arm 32 is fixedly arranged on the movable disk 301.

[0049] As Figure 4 、 Figure 5 shown, the wheel rotation assembly 4 includes: a support cylinder 40, a first motor 41, a gear set 42, and a wheel positioning member 43.

[0050] The support cylinder 40 is vertically and fixedly arranged on the middle fixed plate frame 13.

The main gear 420 is installed on the output shaft of the first motor 41. The driven gear 421 is in transmission connection with the main gear 420 and is rotatably arranged at the top of the support cylinder 40. The wheel positioning member 43 is fixedly arranged on the driven gear 421;

[0051] The horizontal driving assembly 5 is arranged at the bottom of the chassis 10 and includes: a transverse lead screw 50, a second nut seat 51, a second motor 52, a third motor 53, a universal joint coupling 54, and a commutator 55;

[0052] The second motor 52 drives the transverse lead screw 50 to rotate. The second nut seat 51 is sleeved on the transverse lead screw 50 and is connected to the bottom of the horizontal sliding plate frame 12;

[0053] The third motor 53 is in transmission connection with the vertical lead screw 21 through the universal joint coupling 54 and the commutator 55.

[0054] As a preferred solution, to improve the stability of the drive shaft system, the universal joint coupling 54 adopted in this embodiment is a telescopic universal joint coupling.

[0055] By using the wheel flipping assembly and the wheel rotating assembly, any surface of the wheel can be moved to a specific direction, so that the operator can complete the surface treatment or detection of each surface of the wheel at a specific position. At the same time, by using the rotation operation of the wheel rotating assembly, continuous detection and analysis of the wear degree and surface condition of the wheel surface can be realized, so as to realize the complete monitoring and surface treatment of the annular wheel surface (friction contact surface). The whole process is fast, the operation is simple, and the manual demand and equipment demand for the corresponding work are effectively reduced.

[0056] The design method of the horizontal driving assembly on the one hand greatly reduces the demand for driving equipment, and at the same time uses the same-source drive to realize the synchronous movement of movable mechanisms such as the left and right side frames, obtaining better positioning and clamping effects while simplifying the structure and reducing power consumption.

[0057] Particularly, to ensure stable operation and prevent transmission failure caused by long-term stress or collision and friction between structures, in this embodiment, the horizontal driving assembly 5 further includes a drive shaft 56; the drive shaft 56 is in transmission connection with the third motor 53, and both ends of the drive shaft 56 are respectively connected to the two transverse lead screws 50 through universal joints. The two transverse lead screws 50 drive the two horizontal sliding plate frames 12 through the second nut seats 51 sleeved on them; bearing seats 100 and lead screw positioning seats 101 for supporting the drive shaft 56 and the transverse lead screws 50 are arranged at the bottom of the chassis 10.

[0058] The indirect transmission connection method through the transmission shaft - universal joint - transverse lead screw can improve the stability of the traditional system, avoid problems such as transmission failure caused by misalignment and deformation of the transmission shaft system, convert the long shaft system into short shaft connections, and improve the structural stability.

[0059] Particularly, to simplify the structural design and installation method, a first through-hole 12a is provided on the horizontal sliding plate frame 12; both ends of the vertical lead screw 21 are respectively connected to the vertical frame 20 and the horizontal sliding plate frame 12 through positioning sleeves 210, and the lower end of the vertical lead screw 21 passes through the first through-hole 12a and is in transmission connection with the commutator 55.

[0060] The vertical frame 20 is a vertical rectangular frame structure, composed of four outer panels 200 and a top plate 201; guide grooves for positioning the vertical guide rails 22 are provided on the panels on the opposite sides of the two vertical frames 20.

[0061] In this embodiment, the chassis 10 adopts a rectangular frame structure, and it can be very conveniently processed and manufactured using traditional section steel materials.

[0062] Particularly, to facilitate the confirmation of the movement positions of the mechanisms on the left and right sides and the relative position relationship between the clamping mechanism and components such as the wheels, in this embodiment, the clamping and flipping assembly 3 further includes a laser ranging displacement sensor 34 provided on the clamping arm 32, and the laser ranging displacement sensor 34 points to one side of the wheel rotating assembly 4. The laser ranging displacement sensor 34 can effectively confirm the relative position and can also cooperate with the wheel rotating assembly to measure and analyze parameters such as the surface smoothness and outer surface dimensions of the wheel.

[0063] Particularly, to facilitate the connection between each drive motor and each transmission shaft and lead screw, the device also includes a planetary reducer as needed.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
