Description

Technical Field

[0001] This application relates to the technical field of wheel hub processing, and in particular to a clamping fixture for deburring wheel hubs. Background Technology

[0002] The wheel rim is the part of the wheel where the axle is mounted, commonly known as the "wheel rim" or "steel rim". One side of the wheel spokes has many grooves. Current manufacturing technology generally employs three deburring processes: the first two are done robotically, while the final process requires manual deburring of hard-to-reach areas.

[0003] The current manual deburring method usually involves placing the wheel hub on a tilted clamping platform and then manually deburring the hard-to-reach areas. During the work process, workers need to bend over and squat to deburr the wheel hub completely, which can easily lead to physical fatigue after long hours of work.

[0004] Therefore, there is an urgent need to develop a clamping fixture that can reduce the labor intensity of workers. Utility Model Content

[0005] The purpose of this application is to provide a clamping fixture for deburring wheel hubs to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides a clamping fixture for deburring wheel hubs, employing the following technical solution: A clamping fixture for deburring wheel hubs includes a base frame and a clamping platform inclinedly mounted on the base frame. The clamping platform includes a base and a rotating disk. The base is adjustablely mounted on the base frame, and the rotating disk is rotatably connected to the base. A reduction stepper motor is fixed on the base, and a drive gear is fixed to the output shaft of the reduction stepper motor. An annular gear ring is fixed around the rotating disk, and the drive gear meshes with the annular gear ring. A support block is fixed on the surface of the rotating disk. Three quick clamps are also evenly arranged on the rotating disk in a ring. Several through slots are evenly opened on the surfaces of the base and the rotating disk. A dust suction hood is provided on the side of the base away from the rotating disk.

[0007] Preferably, the bottom end of the base is rotatably connected to the base frame, a support rod is hinged to one side of the base, a lead screw assembly is fixed on the base frame, and one end of the support rod is hinged to the lead screw assembly.

[0008] Preferably, the lead screw assembly includes a support base, a screw, a nut seat, and a handle. The support base is fixed on the base frame, the screw is rotatably connected inside the support base, the handle is fixed to the end of the screw, the nut seat is matched and disposed on the screw, and one end of the support rod is hinged to the nut seat.

[0009] By adopting the above technical solution, the base can be adjusted and installed on the frame, which can meet the needs of workers of different heights. Workers can turn the screw with the handle, and the screw drives the nut seat to adjust the position. The nut seat can adjust the position of the support rod, thereby adjusting the angle of the base.

[0010] Preferably, a safety bar is hinged to the other side of the base, and a strip groove is provided on the base frame corresponding to the position of the safety bar. A limit nut is threaded onto the safety bar.

[0011] By adopting the above technical solution, during adjustment, the limit nut is first moved to leave adjustment space; after adjustment, the limit nut is then adjusted to the bottom frame, at which point the limit nut can play the role of limit protection.

[0012] The surface of the support block is provided with a placement groove that is compatible with the wheel hub.

[0013] Preferably, in order to improve the workshop environment, the dust collection hood is connected to a vacuum cleaner.

[0014] In summary, this application includes at least one of the following beneficial technical effects: 1. The clamping fixture for deburring wheel hubs has a simple structure and is easy to manufacture. By using a speed reduction stepper motor to intermittently drive the rotating disk to rotate, the rotating disk drives the wheel hub to rotate. Workers can perform comprehensive deburring on the surface of the wheel hub without bending over or squatting, which greatly reduces labor intensity and improves production efficiency. 2. The base is adjustable and mounted on the frame to accommodate workers of different heights. Workers can turn the screw with the handle to adjust the position of the nut seat, which in turn adjusts the position of the support rod, thereby adjusting the angle of the base.

[0019] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0020] This application discloses a clamping fixture for deburring wheel hubs, referring to... Figure 1-3 The device includes a base frame 1 and a clamping platform tilted on the base frame 1. The clamping platform includes a base 2 and a rotating disk 3. The base 2 is adjustablely mounted on the base frame 1. The rotating disk 3 is rotatably connected to the base 2. A reduction stepper motor 4 is fixed on the base 2. A drive gear 41 is fixed on the output shaft of the reduction stepper motor 4. An annular gear ring 31 is fixed on the periphery of the rotating disk 3. The drive gear 41 meshes with the annular gear ring 31. A support block 32 is fixed on the surface of the rotating disk 3. The support block 32 has a placement groove adapted to the wheel hub. Three quick clamps 33 are also evenly arranged on the rotating disk 3. The three quick clamps 33 are arranged in a ring. Several through slots 34 are evenly arranged on the surfaces of the base 2 and the rotating disk 3. A dust collection hood 5 is provided on the side of the base 2 away from the rotating disk 3. A vacuum cleaner is connected to the outside of the dust collection hood 5.

[0021] Reference Figure 2 The base 2 is rotatably connected to the base frame 1 at its bottom end. A support rod 6 is hinged to one side of the base 2. A screw assembly 7 is fixed on the base frame 1. One end of the support rod 6 is hinged to the screw assembly 7. The screw assembly 7 includes a support seat, a screw, a nut seat, and a handle. The support seat is fixed to the base frame 1. The screw is rotatably connected inside the support seat. The handle is fixed to the end of the screw. The nut seat is matched and set on the screw. One end of the support rod 6 is hinged to the nut seat.

[0022] The base 2 is adjustable and mounted on the base frame 1 to accommodate workers of different heights. Workers can turn the screw with the handle, which drives the nut seat to adjust its position. The nut seat can adjust the position of the support rod 6, thereby adjusting the angle of the base 2.

[0023] To reduce dust entering the screw and affecting the transmission, a bellows cover (not shown in the figure) can be installed on the surface of the screw assembly 7.

[0024] Reference Figure 1 A safety bar 8 is hinged to the other side of the base 2. A strip groove 11 is provided on the base frame 1 at the position corresponding to the safety bar 8. A limit nut 9 is threadedly connected to the safety bar 8.

[0025] During adjustment, first move the limit nut 9 to allow adjustment space; after adjustment, adjust the limit nut 9 back onto the base frame 1. At this time, the limit nut 9 can play the role of limit protection.

[0026] The implementation principle of a clamping fixture for deburring wheel hubs according to an embodiment of this application is as follows: Workers place the wheel hub on the support block 32 and press it firmly with three quick clamps 33. Then, they use a handheld grinder to grind the dead corners of the wheel hub facing them. The deceleration stepper motor 4 can drive the rotating disk 3 to rotate intermittently according to the settings. Workers can deburr the wheel hub surface without bending over or squatting, which greatly reduces labor intensity and improves production efficiency.

[0027] By installing a dust hood 5 and a vacuum cleaner, the dust generated during the polishing process can be removed, greatly improving the workshop environment.

[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
