DETAILED DESCRIPTION OF THE INVENTION

[0017] In order to deepen the understanding of the present invention, the following will further elaborate on the present invention in combination with embodiments. These embodiments are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.

[0018] According toFigures 1-7 As shown in the figure, this embodiment proposes a high-precision cutting and grinding device for automotive parts, including a workbench 1, a support plate 2, a cutting mechanism, and a clamping mechanism. The workbench 1 and the support plate 2 are fixedly connected. A cutting mechanism is provided above the workbench 1, and the cutting mechanism is fixedly connected to the support plate 2. A clamping mechanism for fixing the workpiece is provided directly below the cutting mechanism on the workbench 1; The cutting mechanism includes a transverse movement mechanism 3, a longitudinal movement mechanism 4, a lifting mechanism 5, a first adjustment component, and a cutting and grinding mechanism 18. Among them, the longitudinal movement mechanism 4 is fixedly connected to the upper end of the support plate 2. The transverse movement mechanism 3 is located below the longitudinal movement mechanism 4 and is linked to the longitudinal movement mechanism 4. The lifting mechanism 5 is located below the transverse movement mechanism 3 and is fixedly connected to the transverse movement mechanism 3. The lower part of the lifting mechanism 5 is fixedly connected to the cutting and grinding mechanism 18 through the first adjustment component; Both the transverse movement mechanism 3 and the longitudinal movement mechanism 4 adopt traditional screw drive mechanisms, which will not be elaborated here in detail. The lifting mechanism 5 adopts a hydraulic cylinder, which is also prior art. This device uses the transverse movement mechanism 3, the longitudinal movement mechanism 4, and the lifting mechanism 5 to drive the cutting and grinding mechanism 18 to move horizontally and vertically and to lift in height, thus facilitating the cutting and grinding work.

[0019] The cutting and grinding mechanism 18 includes a driving motor 6, a mounting seat 7, an assembly component, a numerically controlled cutting blade 8, a grinding head 9, and a telescopic cylinder 10. One end of the driving motor 6 is connected to the first adjustment component, and the other end of the driving motor 6 is fixed with a mounting seat 7. The numerically controlled cutting blade 8 is installed on the mounting seat 7 through the assembly component. A through hole 11 is provided in the center of the numerically controlled cutting blade 8. An opening is provided at one end of the mounting seat 7 close to the through hole 11 of the numerically controlled cutting blade 8. The opening extends into the interior of the mounting seat 7 and forms an installation cavity 12. A grinding head 9 is slidably installed in the installation cavity 12, and the grinding head 9 is fixed to the inner wall of the installation cavity 12 through the telescopic cylinder 10.

[0020] This device opens a through hole 11 at the center position of the traditional numerically controlled cutting blade 8, then installs it on the mounting seat 7 through the assembly component, and drives the mounting seat 7 to rotate through the driving motor 6, thereby driving the numerically controlled cutting blade 8 to rotate, so as to cut the part. At the same time, an installation cavity 12 is provided inside the mounting seat 7, and a grinding head 9 is fixed inside it through the telescopic cylinder 10. When the grinding head 9 is extended through the telescopic cylinder 10 and cooperates with the first adjustment component and the clamping mechanism, the driving motor 6 drives the grinding head 9 to rotate, and then the grinding work is carried out. By integrating cutting and grinding into one structure, it greatly facilitates the staff to cut and grind the parts, without the need to replace the machine tool, and also reduces the procurement of equipment.

[0021] The assembly component includes a clamping joint 13, a clamping seat 14, and a fixing bolt 15. The clamping seat 14 is fixed on the outer wall of the mounting seat 7. The insertion end of the clamping joint 13 passes through the through hole 11 from one end of the numerical control cutting blade 8 and then inserts into the clamping seat 14 and is fixed by the fixing bolt 15.

[0022] The numerical control cutting blade 8 is limited by the limiting end of the clamping joint 13, and then the clamping joint 13 is fixed to the clamping seat 14 by the fixing bolt 15, thereby fixing the numerical control cutting blade 8. To further enhance the fixing effect, a clamping groove can be provided in the through hole 11, and a clamping block can be provided on the clamping joint 13.

[0023] The outer diameter of the grinding head 9 is smaller than the inner diameter of the clamping joint 13, and the outer diameter of the limiting end of the clamping joint 13 is larger than the diameter of the through hole 11.

[0024] The first adjustment component includes an adjustment seat 16, a connection block 17, and a drive seat 18. The top of the adjustment seat 16 is fixedly connected to the bottom of the lifting mechanism 5. The lower end of the adjustment seat 16 is rotatably installed with the connection block 17. A first drive chamber 19 for driving the connection block 17 to rotate is fixed on the outer wall of the adjustment seat 16. One end of the connection block 17 is fixedly connected to the mounting seat 7.

[0025] The first drive chamber 19 adjusts the angle of the grinding head 9 by driving the connection block 17 to rotate within the adjustment seat 16, thereby adjusting the grinding angle. The first drive chamber 19 adopts the principle of gear transmission, which is a prior art and will not be described in detail here.

[0026] The clamping mechanism includes a clamping seat 20 and a second adjustment component. There are multiple groups of the clamping seats 20, and the multiple groups of clamping seats 20 are equally spaced. The workbench 1 is also provided with a second adjustment component for driving the clamping seat 20 to move. The workbench 1 is also provided with corresponding storage bins 21 at positions below the multiple groups of clamping seats 20. A bin door 22 adapted to the storage bin 21 is provided on the side wall of the workbench 1. The parts are clamped by the multiple groups of clamping seats 20. This device is applicable to the cutting and grinding of plate-shaped and columnar parts. The stability during cutting and grinding is ensured by the multiple groups of clamping seats 20. At the same time, the position of the clamping seat 20 can be adjusted by the second adjustment component, thereby adjusting the angle of the parts and cooperating with the grinding head 9 and the numerical control cutting blade 8 for work.

[0027] The clamping seat 20 includes a clamping drive bin 23, clamping arms 24, clamping blocks 25, a connecting seat 26, and electromagnetic adsorption blocks 27. Symmetrically arranged clamping arms 24 are provided at the top of the clamping drive bin 23. Clamping blocks 25 are fixed to the upper ends of the clamping arms 24. Trapezoidal grooves 28 are formed on the adjacent sides of the two groups of clamping blocks 25. The connecting seat 26 is fixed to the bottom of the clamping drive bin 23. The connecting seat 26 and the workbench 1 are adsorbed and fixed through the electromagnetic adsorption blocks 27. A slot 29 adapted to the second adjustment component is also provided on the connecting seat 26.

[0028] The clamping drive bin 23 adopts the driving principle of a bidirectional screw to drive the two groups of clamping arms 24 to clamp synchronously, thereby fixing the parts. The design of the trapezoidal grooves 28 can better clamp and limit columnar parts and plate-like parts. At the same time, through the electromagnetic adsorption fixing method between the connecting seat 26 and the workbench 1, in cooperation with the second adjustment component, a specific number of clamping seats 20 can be moved to further meet the work requirements.

[0029] A cavity is provided inside the clamping block 25. A plurality of liquid spraying ports 30 are provided on the side wall of the clamping block 25 at the outer edge of the trapezoidal groove 28. A liquid inlet 31 is also provided on the clamping block 25.

[0030] Through the setting of the liquid spraying ports 30, grinding liquid can be sprayed during grinding to ensure the grinding effect. The liquid inlet 31 is connected to a water source through a hose to ensure the delivery of the grinding liquid.

[0031] The second adjustment component includes a plug-in board 32, a rotating support seat 33, a recovery water tank 34, filter holes 35, and a moving component. The recovery water tank 34 is provided below the plug-in board 32. The plug-in board 32 and the recovery water tank 34 are connected through the rotating support seat 33. The recovery water tank 34 is slidably connected to the workbench 1. A second drive bin 36 is provided on the rotating support seat 33. Filter holes 35 are provided on the plug-in board 32. A moving component for driving the plug-in board 32 to move is provided at the bottom of the recovery water tank 34.

[0032] The second drive bin 36 also adopts the principle of gear transmission, which is a conventional technology and will not be introduced in detail here. The device drives the plug-in board 32 to rotate through the second drive bin 36, thereby driving the parts clamped on the clamping seat 20 to rotate, making the inclination angle thereof adapted to the grinding head 9, so as to grind the cutting end of the parts. The design of the filter holes 35 on the plug-in board 32 allows the grinding liquid to flow back through the filter holes 35 and be recovered by the recovery water tank 34.

[0033] The interface of the plug-in board 32 is in an I shape. The plug-in board 32 is adsorbed and fixed to the connecting seat 26 through the electromagnetic adsorption blocks 27. The electromagnetic adsorption fixing method is more convenient for automatic control and ensures the stability when the clamping seat 20 moves.

[0034] The moving component includes a moving bin 37 and a connecting rod 38. A moving bin 37 is provided at the bottom of the workbench 1, and a connecting rod 38 is provided at the top of the moving bin 37. The connecting rod 38 is fixedly connected to the recovery water tank 34. The moving bin 37 drives the connecting rod 38 to drive the recovery water tank 34 and the plug-in board 32 to move. A slot for the connecting rod 38 to move is provided inside the workbench 1.

[0035] The moving bin 37 adopts the principle of screw drive, which is a prior art and will not be described in detail here. The device drives the connecting rod 38 to move through the moving bin 37, thereby driving the recovery water tank 34 and the plug-in board 32 to move. After the parts are cut, by selecting a specific number of jigs, the plug-in position of the plug-in board 32 is adjusted. By controlling the electromagnetic adsorption block 27, the corresponding number of clamping seats 20 can be controlled to separate from the workbench 1 and be fixed to the plug-in board 32. Then, the plug-in board 32 is rotated by the second drive bin 36, so that the end of the part corresponds to the grinding head 9, and thus grinding can be carried out.

[0036] By integrating the numerical control cutting blade 8 and the grinding head 9, this high-precision cutting and grinding device for automotive parts enables the staff to perform grinding after cutting without having to replace the machine tool, which is quite convenient. At the same time, the factory only needs to purchase one machine tool to meet the needs of cutting and grinding, without having to purchase two machine tools separately, greatly reducing the cost.

[0037] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
