Description

Technical Field

[0001] This utility model relates to the field of drilling machine tool technology, specifically a wheel hub drilling machine tool. Background Technology

[0002] In the automotive manufacturing industry, wheel hubs, as core components connecting the vehicle body and wheels, have their bolt holes, positioning holes, and other holes' machining accuracy directly affecting vehicle driving safety and assembly stability. Currently, most wheel hub drilling machine tools adopt a single-spindle, hole-by-hole machining mode, where a single spindle drives a cutting tool to drill multiple holes on the wheel hub sequentially. Because each hole needs to be positioned and machined individually, the overall machining time for a single wheel hub is relatively long. Furthermore, after machining, the machine needs to be stopped to remove the machined wheel hub and then reposition and fix a new wheel hub to be machined. This loading and unloading process cannot be carried out in parallel with the machining process, undoubtedly further increasing time consumption. This leaves the equipment idle for extended periods during non-cutting phases, resulting in low overall production efficiency and making it difficult to meet the demands of modern automotive production lines for efficient and continuous production.

[0003] Therefore, this utility model provides a wheel hub drilling machine tool. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 A wheel hub drilling machine tool includes a machine tool body 1 and a drilling machine 11. A rotating column 2 and a moving frame 3 are arranged inside the machine tool body 1, and the moving frame 3 is located below the rotating column 2.

[0021] The rotating column 2 has three-jaw chucks 21 installed at both ends of its bottom. A support rod 22 runs through the rotating column 2 and is installed inside the machine tool body 1. A motor that controls the rotation of the support rod 22 is installed on one side of the machine tool body 1.

[0022] It should be noted that, in this embodiment, the support rod 22 drives the two three-jaw chucks 21 to exchange positions via the rotating column 2.

[0023] The movable frame 3 slides laterally inside the machine tool body 1. A mesh disk 31 is provided on the movable frame 3. The mesh disk 31 is located directly below the rotating column 2. A horizontal plate 32 is installed on the inner wall of the movable frame 3. An electric telescopic rod 33 is installed at the bottom of the horizontal plate 32. The output end of the electric telescopic rod 33 is installed at the bottom of the mesh disk 31.

[0024] It should be noted that the cloud drive 31 described in this embodiment does not contact the three-claw chuck 21.

[0025] Specifically, this wheel hub drilling machine tool achieves efficient continuous processing through the coordinated action of multiple mechanisms: During machine operation, a motor drives a support rod 22 that passes through the rotating column 2, causing the rotating column 2 to rotate around the support rod 22, which in turn drives the three-jaw chucks 21 installed at both ends to exchange positions, forming a "machining station" and a "loading / unloading station"; During the drilling operation, the drilling machine 11 performs single-spindle hole-by-hole machining on the wheel hub held by the three-jaw chuck 21 in the machining station, while at the same time, the other three-jaw chuck 21 in the loading / unloading station moves laterally with the help of a sliding frame. The frame 3 and the mesh tray 31, which is driven to rise and fall by the electric telescopic rod 33 at the bottom of the horizontal plate 32, simultaneously carry out the loading and unloading operations of the wheel hubs. The mesh tray 31 receives the wheel hubs to be loaded or processed during the loading and unloading process. Since the mesh tray 31 does not contact the three-jaw chuck 21, it does not interfere with the operation of the processing station. After the processing station completes a round of drilling, the rotating column 2 rotates to exchange the positions of the two chucks, so that the chuck that has completed loading and unloading enters the processing station and the chuck of the original processing station enters the loading and unloading station. This cycle is repeated to achieve parallel operation of "processing-loading and unloading". The hole diameter on the mesh tray 31 facilitates the falling of debris.

[0026] In one embodiment of this utility model, such as Figures 1-4 As shown, a transverse moving support 12 is installed at the top of the machine tool body 1, and a vertical moving support 13 is slidably connected to the transverse moving support 12. The drilling machine 11 is slidably connected to one side of the vertical moving support 13.

[0027] Specifically, the transverse moving support 12 at the top of the machine tool body 1 can drive the vertical moving support 13 and the drilling machine 11 to achieve horizontal position adjustment. The vertical moving support 13 can drive the drilling machine 11 to perform vertical displacement adjustment. Through the linkage sliding in the transverse and vertical directions, the drilling machine 11 can flexibly adjust the processing position according to the coordinate requirements of different holes on the hub, so as to achieve precise positioning and drilling operations for each hole on the hub.

[0028] In one embodiment of this utility model, such as Figures 1-4 As shown, arc-shaped baffles 23 are installed on both sides of the rotating column 2, and the support rod 22 is located between the two arc-shaped baffles 23. The arc-shaped baffles 23 divide the two three-jaw chucks 21 into sections.

[0029] It should be noted that the two arc-shaped baffles 23 described in this embodiment form a circle, and the circle is the same size as the mesh disk 31.

[0030] Specifically, the arc-shaped baffles 23 installed on both sides of the rotating column 2 form a partitioned structure with the support rod 22 as the interval, which divides the three-jaw chucks 21 at both ends of the rotating column 2 into independent areas in space; the two arc-shaped baffles 23 are combined to form a circle with the same size as the mesh tray 31. During the rotation of the rotating column 2 and the three-jaw chucks 21 to exchange positions and process and load and unload, the arc-shaped baffles 23 can prevent the debris, coolant and other materials generated by the processing station from entering the loading and unloading station, and at the same time avoid the loading and unloading operation from interfering with the processing area, so as to achieve effective spatial isolation between the two stations.

[0031] In one embodiment of this utility model, such as Figures 1-4 As shown, the machine tool body 1 has two track grooves 14 on both sides inside, and the moving frame 3 is slidably connected to the inner wall of the two track grooves 14. A handle 34 is installed on one side of the moving frame 3.

[0032] Specifically, the machine tool body 1 has two side rail grooves 14 inside to provide sliding guidance for the moving frame 3; the moving frame 3 slides with the inner wall of the rail groove 14, and achieves stable lateral sliding with the constraint of the rail groove 14. The operator can manually control the sliding of the moving frame 3 in the rail groove 14 by operating the handle 34 on one side of the moving frame 3, thereby adjusting the position of the moving frame 3 and the mesh disk 31 and other components, and coordinating the connection between the wheel hub loading and unloading and the processing station.

[0033] In one embodiment of this utility model, such as Figures 1-4 As shown, a support plate 15 is detachably connected to the bottom of the machine tool body 1. The support plate 15 is located below the movable frame 3, and the electric telescopic rod 33 does not contact the support plate 15.

[0034] Specifically, the support plate 15 can catch debris, coolant or small parts that may fall during processing, preventing them from falling directly to the bottom of the machine tool and causing accumulation. Due to its detachable nature, it is easy to disassemble and clean regularly to maintain the cleanliness of the area under the machine tool.

[0035] In one embodiment of this utility model, such as Figures 1-4 As shown, an electromagnetic chuck controller 4 is installed on one side of the machine tool body 1, and an electric chuck 41 is provided on one side of the electromagnetic chuck controller 4. The electric chuck 41 is flush with the inner side of the machine tool body 1, and the electric chuck 41 is magnetically attracted to the side wall of the moving frame 3.

[0036] Specifically, when the moving frame 3 slides to the preset loading / unloading position in the track groove 14, the electromagnetic chuck controller 4 causes the electric chuck 41 to become magnetic, adsorbing and fixing it to the side wall of the moving frame 3. This ensures that the moving frame 3 and the mesh tray 31 remain stable during the loading and unloading of the auxiliary hub, avoiding displacement due to vibration, etc. When it is necessary to adjust the position of the moving frame 3, the electromagnetic chuck controller 4 controls the electric chuck 41 to demagnetize, releasing the adsorption state, allowing the moving frame 3 to slide flexibly along the track groove 14, realizing the rapid fixing and release of the moving frame 3, and ensuring the accuracy and stability of the loading / unloading operation.

[0037] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0038] Working principle: The motor drives the support rod 22 that runs through the rotating column 2, causing the rotating column 2 to rotate. This drives the three-jaw chucks 21 at both ends to form a dual workstation for processing and loading / unloading, and to achieve position exchange. During drilling, the drilling machine 11 adjusts its position through the horizontal moving support 12 and the vertical moving support 13 to process the hub hole by hole at the processing workstation. At the same time, the loading / unloading workstation uses the moving frame 3 that slides along the track groove 14 and the mesh disk 31 driven by the electric telescopic rod 33 to complete the loading and unloading of the hub. The electromagnetic chuck controller 4 controls the electric chuck 41 to adsorb and fix the moving frame 3. The arc-shaped baffles 23 on both sides of the rotating column 2 separate the two workstations and block debris interference. The bearing plate 15 catches the falling objects, and the hole diameter of the mesh disk 31 facilitates the falling of debris. All mechanisms work together to achieve parallel processing and loading / unloading, improving efficiency.
