Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] See also Figure 1-8 The present invention provides a technical solution: a cutting device for processing a hub riser, comprising a base plate 1, a controller 3, a moving mechanism arranged on the base plate 1, a cutting mechanism and a cooling mechanism arranged on the moving mechanism, the cutting mechanism is used to cut the hub riser, the cooling mechanism is used to cool the hub riser during cutting, and a clamping mechanism arranged on one side of the cutting mechanism is used to clamp the hub;

[0037] The moving mechanism includes a horizontal component and a vertical component. The vertical component is arranged above the horizontal component. The horizontal component includes a connecting plate 21 slidably connected to the base plate 1, and a first drive 23 fixed on the base plate 1. The first drive 23 is hinged to the bottom of the connecting plate 21. Starting the first drive 23 to extend and contract drives the vertical component to move horizontally on the base plate 1.

The output end of the second drive is hinged to the connecting plate 22. The activated second drive extends and contracts to drive the connecting plate 22 to move horizontally.

[0039] The combined movement of the first drive 23 and the second drive can drive the cutting mechanism and the cooling mechanism to move horizontally and vertically, so as to facilitate the cutting and cooling of the hub riser.

[0040] It should be noted that the first drive 23 and the second drive may be cylinders;

[0041] The cutting mechanism includes a cutting component and a swinging component. The swinging component can drive the cutting component to swing up and down to change the cutting angle.

[0042] The cutting assembly includes a fixed plate 9, which is fixed above the connecting plate 22. A driving plate 10 is hinged on the fixed plate 9, and a third driving plate 11 is fixed on the driving plate 10. A rotating rod 17 is connected to the other end of the driving plate 10 by a bearing. A transmission belt 12 is connected between one end of the rotating rod 17 and the third driving plate 11. A cutting disc 14 and a cutting disc 2 15 are fixed to the other end of the rotating rod 17. The cutting disc 2 15 is smaller than the cutting disc 14, and the cutting disc 14 is located on one side of the cutting disc 2 15.

[0043] It should be added that the cutting disc 14 is a roughing disc, and the cutting disc 2 15 is a finishing disc;

[0044] When it is necessary to cut the hub riser, start the third drive 11 to drive the rotating rod 17 to rotate through the transmission belt 12, and drive the cutting disc 14 and the cutting disc 2 15 to rotate through the rotating rod 17, and then drive the cutting assembly to move to the hub riser through the moving mechanism, and cut off the riser through the cutting disc 14. After the riser is cut off, continue to perform rough processing on the hub blank surface. When fine processing is required, control the movement of the cutting assembly again through the moving mechanism, so that the cutting disc 2 15 moves to the hub, and fine processing is performed on the hub surface to ensure the processing accuracy. Through this step, the riser cutting and the hub surface rough processing and fine processing are integrated to improve the processing efficiency.

[0045] The swing assembly includes a fourth drive 16 fixed on the bottom plate 1, and the output end of the fourth drive 16 is hinged to the drive plate 10. The fourth drive 16 is started to drive the drive plate 10 to swing on the fixed plate 9, thereby changing the cutting angle of the cutting assembly and expanding the cutting range.

[0046] It should be noted that the third drive 11 may be a motor, and the fourth drive 16 may be a cylinder.

[0047] The clamping mechanism includes a chuck assembly and a detection assembly. The chuck assembly includes a driving shell 2 fixed on a base plate 1. A three-jaw chuck 4 is provided on one side of the driving shell 2. A motor drive is provided inside the driving shell 2. The motor drive is fixedly connected to the three-jaw chuck 4. The wheel hub is clamped by the three-jaw chuck. The motor drive can drive the three-jaw chuck 4 to rotate, thereby driving the wheel hub to rotate.

[0050] After the riser cutting of the hub surface is completed, the camera 33 is started to detect whether there are pits at the hub riser, and the electric telescopic rod 18 is started to contract to drive the roughness detector 20 to contact the hub surface. At this time, the motor drives the three-jaw chuck 4 to rotate slowly, and starts to detect the roughness of the hub surface, and transmits the detected roughness value to the controller 3.

[0051] The cooling mechanism includes a pipeline assembly and a collecting assembly. The pipeline assembly includes a connecting plate three 6 fixed on the connecting plate two 22. A central pipe 7 is fixed on the connecting plate three 6. The other end of the central pipe 7 is connected to a water source 30. A first pump body 29 is connected between the central pipe 7 and the pipeline of the water source 30. Branch pipes 8 and vertical pipes 13 are distributed on the central pipe 7. A valve 25 is connected to each group of branch pipes 8. The branch pipes 8 are aligned with the wheel hub. The vertical pipes 13 are bent pipes. The outlets of the vertical pipes 13 are aligned with the cutting disk one 14 and the cutting disk two 15. Nozzles are connected to the branch pipes 8 and the vertical pipes 13. When cutting, the first pump body 29 is started to transfer the coolant from the water source 30 to the central pipe 7, and the coolant is sprayed to the wheel hub and the cutting disk one 14 and the cutting disk two 15 through the branch pipes 8 and the vertical pipes 13 for cutting cooling.

[0052] The collecting assembly includes a collecting box 5 fixed on the bottom plate 1, a filter plate 26 is arranged inside the collecting box 5, and the collecting box 5 is divided into an upper chamber 27 and a lower chamber 28 by the filter plate 26. A connecting pipe 24 is arranged on one side of the lower chamber 28, one end of the connecting pipe 24 is connected to a filter 31, the filter 31 is connected to the water source 30 by a pipeline, and a second pump body 32 is connected to the connecting pipe 24.

[0053] The chips fall onto the collection box 5, and the chips are separated from the liquid by the filter plate 26, so that the subsequent staff can directly remove the impurities. Then the second pump body 32 is started, and the liquid in the lower chamber 28 is pumped into the filter 31 through the connecting pipe 24 to filter the liquid. The filtered liquid then flows into the water source 30 to enter the next cycle, thereby improving the utilization rate of the coolant.

[0054] It should be noted that the first pump body 29 and the second pump body 32 may be liquid pumps.

[0055] The controller 3 includes a cutting control system, and the cutting detection control system includes a data acquisition module and a cutting control module. The data acquisition module includes a roughness receiving submodule, an analysis submodule and an image receiving submodule. The roughness receiving submodule is electrically connected to the roughness detector 20, and the image receiving submodule is electrically connected to the camera 33.

[0056] The roughness receiving submodule includes a position marking unit, and the image receiving submodule includes a hub thickness recognition unit and a pit depth recognition unit;

[0057] The cutting control module includes a cutting detection control submodule, a rotation control submodule, a swing submodule and an alarm submodule. The cutting control submodule is electrically connected to the first drive 23 and the second drive, the rotation control submodule is electrically connected to the motor drive, and the swing submodule is electrically connected to the fourth drive 16.

[0058] The cutting detection control system includes the following operating steps:

[0059] Step 1: When cutting, turn on the first pump body 29 to pump the cooling water in the water source 30 to the hub surface, cutting disc one 14 and cutting disc two 15, which can take away the chips and play a role in cooling when the cutting mechanism is working;

[0060] Step 2: Control the moving mechanism to drive the cutting disc one 14 and the cutting disc two 15 to move closer to the hub surface to cut the riser;

[0061] Step 3: After cutting the riser, first detect the depth of the riser shrinkage cavity, analyze the degree of the riser shrinkage cavity, judge the quality of the hub, and then rough-machine the surface of the hub blank. After rough machining, finish machining is carried out to ensure the machining quality of the hub;

[0062] Specifically, when cutting the riser, first control the third drive 11 to drive the cutting disc one 14 to rotate, cut off the protruding riser on the hub surface. After cutting it completely, if there is a shrinkage cavity at the riser, a concave pit will appear on the end face of the hub. At this time, start the motor drive through the rotation control sub-module, so as to drive the three-jaw chuck 4 to rotate slowly, move the cut riser part of the hub under the camera 33, take a photo of the hub surface and transmit it to the image receiving sub-module, and identify the depth of the concave pit through the concave pit depth identification unit. At this time, it is necessary to calculate the size of the depth of the concave pit and the thickness of the hub blank to judge whether there is a shrinkage cavity in the hub riser. Specifically, the staff sets the thickness to be machined of the hub as h in the hub thickness identification unit, identifies the thickness of the unprocessed overall hub blank as d through the camera 33, and the depth of the concave pit as w. Through calculation, when w < d - h, it means that the riser shrinkage cavity is within the allowable range, and subsequent blank cutting and machining can be carried out. When w > d - h, it means that the depth of the concave pit is large, indicating that the riser shrinkage cavity is serious, proving that there is a problem with the quality of the hub, and the staff needs to remove it. This step can judge the quality of the hub casting according to the degree of the riser shrinkage cavity.

[0063] When the riser shrinkage cavity is within the allowable range, it is necessary to machine the hub thickness blank. Specifically, continue to control the cutting disc one 14 to machine the surface of the hub blank, further judge the proportion of the depth of the concave pit relative to the remaining blank thickness, and then select a suitable cutting method. The formula is: , where is the remaining blank thickness, h is the thickness to be machined of the hub, d is the thickness of the unprocessed overall hub blank, p is the proportion of the depth of the concave pit relative to the remaining blank thickness. When , it means that the concave pit is shallow, , it means that the concave pit is deep.

[0064] When the pit is shallow, the thickness of the hub surface is first processed by the cutting disk 14, and 70% of the thickness is processed first. At this time, the signal is transmitted to the cutting adjustment submodule to adjust the moving distance of the first drive 23 and the second drive, so that the cutting disk 2 15 moves to the hub surface, and the hub surface is fine-processed. When the fine processing is completed, the electric telescopic rod 18 is started to contract and drive the roughness detector 20 to approach the hub surface, and then the three-jaw chuck 4 is driven by the motor to rotate slowly, so that the roughness detector 20 can detect the roughness of the hub after cutting.

[0065] If the roughness of the tested wheel hub surface meets the requirements, it means that the wheel hub surface processing is completed and can be removed to enter the next process. If the roughness of the tested wheel hub surface does not meet the requirements, it is necessary to analyze the location and distribution of the roughness that does not meet the requirements;

[0066] Furthermore, when it is identified that the roughness does not meet the standard, the distribution of the roughness is determined and analyzed through the analysis submodule. When the higher roughness is widely distributed on the hub surface and is greater than half of the hub circumference, it means that the cutting disk 2 15 is damaged and affects the finishing quality, and the cutting disk 2 15 needs to be replaced; when the higher roughness distribution is less than half of the hub circumference, it means that the higher roughness is more concentrated on the hub surface. The position of the higher roughness is marked by the position marking unit, and the signal is transmitted to the rotation control submodule. The motor drive is controlled by the rotation control submodule to start, and the position of the higher roughness side of the hub is rotated to be close to the cutting mechanism. At this time, the cutting disk 2 15 is started again, and the fourth drive 16 is controlled to extend through the swing submodule, thereby driving the drive plate 10 to swing on the fixed plate 1 9, so that the cutting disk 2 15 can be driven to swing up and down a certain angle on the hub surface. When the cutting disk 2 15 swings a certain angle, the concentrated roughness surface can be secondary processed to ensure the hub surface accuracy.

[0067] During the concentrated cutting process, the cooling water pump is continuously controlled to be supplied to the hub surface and the cutting disc 14 and the cutting disc 2 15 to prevent the concentrated cutting heat from being too high and affecting the hub surface roughness again.

[0068] After the secondary processing is completed, the hub surface will be refined again to make the hub thickness reach h, ensuring that the overall roughness meets the qualified requirements and the processing quality is guaranteed.

[0069] When the pit is deep, repeat the above-mentioned cutting process. When it is detected that the roughness does not meet the standard, it is necessary to consider the depth of the pit based on the position of the roughness to determine whether the existence of the pit affects the roughness. Specifically, when the higher roughness is relatively concentrated, the shrinkage hole of the riser is also in a concentrated position, indicating that the riser expansion hole at this position is very likely to cause problems in the surrounding casting. At this time, the signal is transmitted to the alarm sub-module to alarm. When the higher roughness is widely distributed, repeat the steps of shallow pits to continue to fine-tune the hub. Through this step, it can be determined whether the shrinkage hole of the riser affects the surface roughness of the hub, thereby affecting the quality of the hub.

[0070] It should be noted that the moving distances of the first drive 23 and the second drive are set by the staff according to actual conditions.

[0071] It should be added that before using the roughness tester 20 each time, it is necessary to pump cooling water to the hub surface to clean up excess chips to avoid the presence of chips affecting the roughness test and ensure the accuracy of the roughness value test.
