[0006] Preferably, a slidably connected storage box is provided on one side of the workbench, and a fixing clip is slidably connected to the side of the workbench close to the storage box. The storage box can be provided to uniformly collect the debris generated during the grinding process. During the cutting process of high-hardness mechanical parts, the friction between the grinding knife and the parts will generate a large amount of debris. If these debris are not cleaned up in time, it will not only affect the cleanliness of the working environment, but may also interfere with the normal operation of the equipment. The storage box can effectively collect these debris, which is convenient for subsequent cleaning work. Secondly, the storage box can also facilitate the better collection of the sprayed cooling water, which plays a role in recycling. During the cutting process, in order to reduce the temperature and reduce wear, cooling water is usually used to cool the grinding knife and parts. After use, if these cooling waters are directly discharged, it will not only cause a waste of water resources, but also may cause pollution to the environment. The storage box can collect these cooling waters, and after proper treatment, they can be recycled again, which not only saves water resources but also reduces production costs.

[0007] Preferably, a hydraulic rod is provided on one side of the fixing clamp, and a clamping block is movably connected to one side of the fixing clamp.

[0013] Preferably, a slide groove matched with the clamping block is provided on the upper surface of the inner connector, and a push rod structure identical to that in the first connector is provided inside the inner connector.

[0014] Preferably, a slider is provided on the side of the storage box, fixing clamp and polishing plate close to the workbench, and a corresponding slide groove is provided on the workbench. A slider is provided on the side of the storage box, fixing clamp and polishing plate close to the workbench 1, and a corresponding slide groove is provided on the workbench. This design brings great convenience to the overall equipment. Through the cooperation of the slider and the slide groove, the overall setting can be moved more smoothly. When the equipment needs to be overhauled, the operator can easily slide each component along the slide groove to the appropriate position for comprehensive and detailed inspection and maintenance.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The present invention facilitates the adjustment of the direction of the grinding knife at multiple angles through the coordination of the first motor, the worm, the turbine, the movable frame and other structures. The first motor can effectively drive the worm to rotate. When the worm starts to rotate, the turbine coordinated with the worm will drive the movable frame to adjust the angle under the drive of the worm. This adjustment mechanism enables the entire device to change the angle more flexibly during operation. At the same time, the second motor can drive the rotating frame to operate. In this way, the overall setting can achieve multi-angle operation, so that when grinding mechanical parts, it can be operated more conveniently and efficiently, and it is convenient to better grind mechanical parts of various shapes and sizes, thereby greatly improving the quality and efficiency of grinding.

[0017] The present invention facilitates the installation and disassembly of the grinding knife through the quick-release structure through the coordination of the first connecting head, the clamping block, the outer ring, the inner connecting head and other structures. Through the setting of the inner connecting head, it is pushed into the first connecting head. During the pushing process, the clamping groove on the surface of the inner connecting head will gradually approach the clamping block and connect with the clamping block, and the outer ring will also move toward the direction of the first connecting head, so that the clamping block can be pushed up first and then clamped to the inner connecting head downward, so that the entire device can quickly complete the operation by quick release when the grinding knife needs to be replaced. This quick release method not only greatly improves the work efficiency, but also allows the operator to replace the grinding knife more conveniently. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0028] like Figures 1 to 8 As shown, the present invention provides a cutting device for processing high-hardness mechanical parts, including a workbench 1, a grinding plate 6 is slidably connected to one side of the workbench 1, a first motor 7 is arranged on one side of the grinding plate 6, the output shaft end of the first motor 7 is rotatably connected to a worm 8, a second motor 9 is arranged on the side of the grinding plate 6 away from the first motor 7, the output shaft end of the second motor 9 is rotatably connected to a rotating frame 10, a turbine 11 is meshed on one side of the worm 8, the turbine 11 is rotatably connected to a movable frame 12, a sleeve 13 is arranged on the side of the movable frame 12 away from the turbine 11, a first connector 14 is arranged inside the sleeve 13, a push rod 16 is arranged inside the first connector 14, a clamping block 17 is arranged on the side of the first connector 14 away from the sleeve 13, an inner connector 19 is clamped on the side of the first connector 14 away from the sleeve 13, and a grinding knife 20 is arranged on the side of the inner connector 19 away from the first connector 14.

[0029] Through the setting of the first motor 7, the worm 8 can be effectively driven to rotate. When the worm 8 starts to rotate, the turbine 11 matched therewith will drive the movable frame 12 to adjust the angle under the drive of the worm 8. This adjustment mechanism enables the entire device to change the angle more flexibly during operation. At the same time, the setting of the second motor 9 can drive the rotating frame 10 to operate. In this way, the overall setting can realize multi-angle operation, so that when grinding mechanical parts, it can be operated more conveniently and efficiently, and it is convenient to better grind mechanical parts of various shapes and sizes, thereby greatly improving the quality and efficiency of grinding.

[0030] Through the setting of the inner connector 19, it is pushed into the first connector 14. During the pushing process, the groove on the surface of the inner connector 19 will gradually approach the block 17 and be clamped and connected, and the outer ring 18 will also move toward the direction of the first connector 14, so that the block 17 can be pushed up first, and then clamped to the inner connector 19 downward, so that when the grinding knife 20 needs to be replaced, the entire device can be quickly operated by quick release. This quick release method not only greatly improves the work efficiency, but also allows the operator to replace the grinding knife more conveniently.

[0031] like Figure 1 , Figure 7 As shown, a slidably connected storage box 101 is provided on one side of the workbench 1, a slidably connected fixed clamp 2 is provided on the side of the workbench 1 close to the storage box 101, a hydraulic rod 3 is provided on one side of the fixed clamp 2, a clamp block 4 is movably connected on one side of the fixed clamp 2, a bottom clamp 5 is provided on the side of the clamp block 4 away from the fixed clamp 2, and an electric push rod 51 is provided on the side of the bottom clamp 5 close to the fixed clamp 2.

[0032] The above scheme is adopted: a storage box 101 is arranged on one side of the workbench 1. The storage box 101 can collect the debris generated during the grinding process in a unified manner. During the cutting process of high-hardness mechanical parts, the friction between the grinding knife 20 and the parts will generate a large amount of debris. If these debris are not cleaned up in time, it will not only affect the cleanliness of the working environment, but also may interfere with the normal operation of the equipment. The storage box 101 can effectively collect these debris, which is convenient for subsequent cleaning work. Secondly, the storage box 101 can also facilitate the better collection of the sprayed cooling water, which plays a role in recycling. During the cutting process, in order to reduce the temperature and reduce wear, Cooling water is usually used to cool the grinding knife 20 and parts. If the cooling water is discharged directly after use, it will not only waste water resources but also pollute the environment. The storage box 101 can collect the cooling water and can be recycled after proper treatment, which not only saves water resources but also reduces production costs. At the same time, the fixed clamp 2 slidingly connected to one side of the workbench 1 can better clamp different mechanical parts. The design of the fixed clamp 2 can meet the clamping requirements of mechanical parts of various sizes. The setting of the hydraulic rod 3 facilitates the movement of the overall fixed clamp 2 structure, so that the fixed clamp 2 can quickly and accurately locate the position of the part that needs to be clamped.

[0033] like Figure 6 , Figure 7 As shown, the interior of the fixing clamp 2 is provided with a first spring 52, a connecting rod 53, and a second spring 54. The first spring 52 is fixedly connected to the clamp block 4 and the bottom clamp 5. The connecting rod 53 is rotatably connected to the clamp block 4, the bottom clamp 5, and the fixing clamp 2. A sliding groove is provided on one side of the sleeve 13. A sliding rod 15 is provided on the side of the first connecting head 14 close to the sleeve 13. The sliding rod 15 is adapted to the sliding groove. An elastic piece is fixedly connected to the surface of the push rod 16. An inner rod is provided inside the push rod 16 close to the first connecting head 14.

[0034] The above scheme is adopted: a first spring 52, a connecting rod 53, and a second spring 54 are arranged inside the fixing clamp 2. This design enables the electric push rod 51 in the fixing clamp 2 to play a more efficient driving role when working. When the electric push rod 51 is started, the driving force generated by it will be transmitted through a series of transmissions, so that the clamp block 4 moves up and down through the common setting of the first spring 52, the second spring 54 and the connecting rod 53. This up and down movement mechanism has great flexibility and adaptability, and can be automatically adjusted according to different mechanical parts. When facing larger-sized mechanical parts, the clamp block 4 will open appropriately under the action of the spring and the connecting rod 53 to accommodate larger parts; and when facing smaller-sized mechanical parts, the clamp block 4 will fit closely to the surface of the parts, and through the pressure of the spring The compression force provides sufficient clamping force. At the same time, a slide groove is opened on one side of the sleeve 13, and a slide rod 15 is arranged on the side of the first connecting head 14 close to the sleeve 13. This design enables the first connecting head 14 to be flexibly rotated in the sleeve 13 through the setting of the slide rod 15. During the processing, according to different processing requirements, the first connecting head 14 can be extended outward by the rotation of the slide rod 15 in the sleeve 13, which can make the length of the first connecting head 14 longer, thereby expanding the working range of the grinding knife 20 and improving the versatility and practicality of the equipment. In addition, the surface of the push rod 16 is fixedly connected with an elastic piece and an inner rod. When the first connecting head 14 and the inner connecting head 19 are connected to each other, the internal push rod 16 can be effectively coordinated and operated through the setting of the elastic piece and the inner rod.

[0035] like Figure 1 , Figure 7 As shown, an outer ring 18 is provided on the upper surface of the first connecting head 14, a spring ring 180 is provided inside the outer ring 18, a sliding groove matched with the block 17 is provided on the upper surface of the inner connecting head 19, and a support rod 16 structure identical to that in the first connecting head 14 is provided inside the inner connecting head 19, a sliding block is provided on the side of the storage box 101, the fixing clamp 2, and the grinding plate 6 close to the workbench 1, and a corresponding sliding groove is provided on the workbench 1.

[0036] The above scheme is adopted: an outer ring 18 is provided on the upper surface of the first connecting head 14, and a spring ring 180 is provided inside the outer ring 18. When the outer ring 18 moves toward the first connecting head 14, the spring ring 180 can fully play its role and provide a certain elastic force, which can make the clamping of the clamping block 17 more stable and reliable. When the inner connecting head 19 is connected to the first connecting head 14, the clamping block 17 can be tightly clamped in the clamping groove on the surface of the inner connecting head 19 under the elastic force of the spring ring 180, ensuring the firmness of the connection, so that during the working process of the grinding knife 20, there is no It will not easily loosen due to vibration or other external forces, which ensures the stability and safety of the cutting process. At the same time, a slider is provided on the side of the storage box 101, the fixing clamp 2, and the grinding plate 6 close to the workbench 1, and a corresponding slide groove is provided on the workbench 1. This design brings great convenience to the overall equipment. Through the cooperation of the slider and the slide groove, the overall setting can be moved more smoothly. When the equipment needs to be inspected and maintained, the operator can easily slide the various components along the slide groove to the appropriate position for comprehensive and detailed inspection and maintenance.

[0037] The working principle and use process of the present invention:

[0038] First, place the high-hardness mechanical parts to be processed on the workbench 1, clamp the machine with the fixing clamp 2 on the workbench 1, and push the clamp block 4 on the fixing clamp 2 through the setting of the electric push rod 51, so that the clamp block 4 moves upward or downward through the setting of the first spring 52, the second spring 54 and the connecting rod 53, so that the clamp block 4 can better clamp different mechanical parts, and then start the first motor 7, the output shaft of the first motor 7 starts to rotate, driving the worm 8 to rotate. After the worm 8 rotates, the turbine 11 meshing with it starts to rotate under the drive of the worm 8, and the rotation of the turbine 11 drives the movable frame 12 connected to it to adjust the angle. The sleeve 13 on one side of the movable frame 12, the first connecting head 14 and the subsequently connected parts will also change their positions with the angle adjustment of the movable frame 12, so that it can be processed according to different processing needs. The cutting angle of the grinding knife 20 is adjusted, and at the same time, the second motor 9 is started, and the output shaft of the second motor 9 rotates to drive the rotating frame 10 to operate. The operation of the rotating frame 10 further drives the entire grinding plate 6 and various components connected thereto to operate at multiple angles, so that the grinding knife 20 can cut and grind mechanical parts from different directions, thereby improving the flexibility and comprehensiveness of processing. When the grinding knife 20 needs to be replaced, the inner connecting head 19 is pushed into the first connecting head 14. During the pushing process, the groove on the surface of the inner connecting head 19 is connected to the block 17 on the first connecting head 14, and the outer ring moves toward the first connecting head 14, so that the block 17 can be pushed up and then connected to the inner connecting head 19 downward. This quick-release method allows the operator to quickly and conveniently replace the grinding knife 20 to meet different processing requirements.
