Detailed Implementation

[0017] 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.

[0018] Please see Figure 1-5 The present invention provides the following technical solution: A support device for machining wheel hubs includes a support platform 1, a support structure 2 bolted to the top of the support platform 1, and a fixing structure 3 bolted to the outside of the support platform 1. The support structure 2 includes two fixed blocks 21, a movable frame 22, a placement platform 23, a connecting block 24, a lead screw 25, and a servo motor 26. The inner side of the fixed block 21 is slidably connected to the outer wall of the movable frame 22. The top of the movable frame 22 is bolted to the bottom of the placement platform 23. The inner side of the placement platform 23 is movably connected to the outer side of the fixed block 21. The inner side of the movable frame 22 is bolted to the outer side of the connecting block 24. The inner wall of the connecting block 24 is threaded to the outer wall of the lead screw 25. The bottom of the lead screw 25 is bolted to the output end of the servo motor 26. The top of the servo motor 26 is bolted to the bottom of the support platform 1.

[0019] In this embodiment: A support platform 1 is set as the base of the entire support device, bearing the overall weight of the wheel hub, support structure 2, and fixed structure 3. The support structure 2 has two fixed blocks 21 symmetrically arranged and slidably connected to the outer wall of the movable frame 22, providing guidance for the up-and-down movement of the movable frame 22. The movable frame 22 can slide up and down along the inner side of the fixed blocks 21 under the drive of the lead screw 25 and the connecting block 24, driving the placement platform 23 to rise and fall. The top of the placement platform 23 is used to place the wheel hub, ensuring the stability of the wheel hub placement. The connecting block 24 converts the rotational motion of the lead screw 25 into the linear motion of the movable frame 22. The bottom of the lead screw 25 is bolted to the output end of the servo motor 26 and rotates under the drive of the servo motor 26. Through the threaded engagement with the connecting block 24, it drives the connecting block 24 and the movable frame 22 to move up and down, so that the wheel hub can be positioned to the required processing position.

[0020] Specifically, such as Figure 3 , Figure 4 , Figure 5 As shown, the fixed structure 3 includes a stabilizing platform 31, the inner side of which is bolted to the outer side of the support platform 1.

[0021] Specifically, such as Figure 3 , Figure 4 , Figure 5 As shown, a support column 32 is fixedly connected to the rear side of the top of the stabilizing platform 31, and a mounting plate 33 is fixedly connected to the top of the support column 32.

[0022] Specifically, such as Figure 3 , Figure 4 , Figure 5 As shown, a hydraulic cylinder 34 is bolted to the top of the mounting plate 33, and a pressure plate 35 is bolted to the bottom of the hydraulic cylinder 34. The bottom of the pressure plate 35 is movably connected to the top of the placement platform 23.

[0023] In this embodiment: By setting a fixing structure 3, the stabilizing platform 31 provides a stable mounting base for components such as the support column 32 and the mounting plate 33. The support column 32 provides vertical support for the mounting plate 33. The mounting plate 33 provides a mounting platform for the hydraulic cylinder 34 and the fixing rod 4. The pressure plate 35 at the bottom of the hydraulic cylinder 34 contacts the wheel hub on the placement platform 23. By outputting pressure, the wheel hub is tightly fixed to the placement platform 23. The adjustable pressure output function of the hydraulic cylinder 34 can control the fixing pressure according to the material and processing requirements of the wheel hub, avoiding damage to the wheel hub due to excessive pressure. The pressure plate 35 contacts the surface of the wheel hub and can work with the support structure 2 to achieve the function of fixing the wheel hub.

[0024] Specifically, such as Figure 1 , Figure 3 , Figure 4 As shown, fixing rods 4 are bolted to both sides of the bottom of the mounting plate 33, and the bottom of the fixing rods 4 is bolted to the top of the stabilizing platform 31.

[0025] Specifically, such as Figure 3 As shown, the top of the mounting plate 33 has a connection hole 5, and the output end of the hydraulic cylinder 34 passes through the connection hole 5 and is connected to the pressure plate 35.

[0026] In this embodiment: by setting a fixed rod 4 to assist the support column 32, the stability of the mounting plate 33 is enhanced, the lateral force generated by the mounting plate 33 when the hydraulic cylinder 34 is working is balanced, the mounting plate 33 is prevented from tilting, and the vertical pressure of the pressure plate 35 on the hub is ensured. By setting the mounting plate 33 to open the connection hole 5, a through channel is provided for the output end of the hydraulic cylinder 34, ensuring the connection between the output end of the hydraulic cylinder 34 and the pressure plate 35, and ensuring that the pressure can be effectively transmitted.

[0027] Specifically, such as Figure 4As shown, the bottom of the support platform 1 has a mounting hole 6, and the lead screw 25 passes through the mounting hole 6 and is connected to the servo motor 26.

[0028] Specifically, such as Figure 1 , Figure 4 As shown, the top of the fixed block 21 is bolted to the limiting block 7, and the bottom of the limiting block 7 is movably connected to the top of the movable frame 22.

[0029] In this embodiment: the mounting hole 6 opened in the support platform 1 provides a through channel for the lead screw 25, so that the lead screw 25 can be connected to the output end of the servo motor 26 at the bottom, ensuring the stability and accuracy of power transmission. By setting the limit block 7, the rising height of the movable frame 22 is limited to prevent the movable frame 22 from rising excessively and detaching from the fixed block 21, thus playing a safety protection role.

[0030] Working principle: When wheel hub processing is required, the wheel hub processing support device operates with the support platform 1 as the base to support the overall structure. In the support structure 2, after the servo motor 26 is started, its output end drives the lead screw 25 to rotate. The lead screw 25 converts the rotational motion into the linear motion of the connecting block 24 through the threaded engagement with the connecting block 24. This causes the connecting block 24 to drive the movable frame 22 to slide along the inner side of the two fixed blocks 21. The placement platform 23 connected to the top of the movable frame 22 rises and falls together until the wheel hub on the placement platform 23 is adjusted to the required processing height. The limit block 7 restricts the movement of the movable frame 22. The height is increased to prevent it from detaching from the fixing block 21 and to ensure operational safety. At the same time, the fixing structure 3 starts to work. The stabilizing platform 31 is fixed to the outside of the support platform 1, providing an installation base for the support column 32 and the fixing rod 4. The support column 32 and the fixing rod 4 jointly support the mounting plate 33 to ensure its stability. The hydraulic cylinder 34 on the mounting plate 33 connects its output end to the pressure plate 35 through the connecting hole 5. After the hydraulic cylinder 34 is started, it outputs pressure to push the pressure plate 35 downward until the bottom of the pressure plate 35 is in close contact with the surface of the wheel hub on the placement platform 23. The adjustable pressure output firmly fixes the wheel hub to prevent displacement during processing.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
