Description

Technical Field

[0001] The present invention relates to the technical field of pump body cutting, and specifically, it is a pump body casting port cutting device with an adaptive clamping function. Background Art

[0002] The cutting of the pump body casting port is an important link in the pump body manufacturing process, and its cutting quality directly affects the performance and service life of the pump body. During the casting process of the pump body, liquid metal is poured into the mold through the casting port for shaping. Therefore, some metal waste will be left at the casting port and needs to be removed.

[0003] Most of the traditional cutting of the pump body casting port is carried out manually or directly with a single tool. The cutting efficiency is low, the cutting is relatively rough, the accuracy is not high, and the cutting quality is difficult to guarantee. When the tool directly cuts the pump body casting port, it is also easy to cause the rupture of the material to be cut. At the same time, after the pump body is cast, due to the contact of the casting port with the external air, the temperature may drop unevenly, resulting in cracks or holes inside the casting port, which may appear after the waste at the casting port is removed, and may affect the subsequent use of the pump body. Summary of the Invention

[0004] The purpose of the present invention is to provide a pump body casting port cutting device with an adaptive clamping function to solve the problems raised in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions: The cutting device cuts the pump body casting port. The cutting device includes a fixing mechanism, a clamping mechanism, a cutting mechanism, a cut surface grinding mechanism, and a defect marking mechanism. The fixing mechanism is connected to the clamping mechanism, the fixing mechanism is connected to the cutting mechanism, the fixing mechanism is connected to the cut surface grinding mechanism, and the cut surface grinding mechanism is connected to the defect marking mechanism.

[0006] In the present invention, the fixing mechanism is used to fix other mechanisms and provide a support for other mechanisms. The clamping mechanism is used to clamp and fix the pump body that needs to be cut at the casting port to prevent the pump body from moving during the casting port cutting process and affecting the cutting. The cutting mechanism is used to cut the pump body casting port and remove the excess waste after casting for subsequent use. The cut surface grinding mechanism is used to grind the cut surface of the pump body after cutting and remove burrs and the like generated by cutting. The defect marking mechanism is used to detect cracks and depressions on the cut surface after grinding to prevent cracks and depressions inside the pump body due to uneven cooling after casting and appear after the casting port is cut. Through detection, it is convenient for subsequent repair or other operations.

[0007] Furthermore, the fixing mechanism includes a fixing base plate and side baffles. There are three side baffles. The fixing base plate and the side baffles are firmly connected. A moving groove is provided on the fixing base plate. The fixing base plate is connected to the clamping mechanism, the moving groove is connected to the clamping mechanism, the fixing base plate is connected to the cutting mechanism, the fixing base plate is connected to the incision grinding mechanism, and the side baffles are connected to the incision grinding mechanism.

[0008] In the fixing mechanism, this mechanism is used to provide support for other mechanisms of the cutting equipment. The fixing base plate is used to support other mechanisms and provide a place for the mechanisms to operate. There are three side baffles. The three side baffles surround three sides of the fixing base plate. There is no side baffle on the side close to the back of the clamping mechanism. The three side baffles mainly fix the base plate and can also block the flying debris that may appear during subsequent cutting and grinding to a certain extent, making it only fall on the fixing base plate for subsequent cleaning.

[0009] Furthermore, the clamping mechanism includes a pushing hydraulic cylinder and a support rod. The fixed end of the pushing hydraulic cylinder is firmly connected to the moving groove. The support rod is placed in the moving groove. The output end of the pushing hydraulic cylinder is firmly connected to the support rod. The bottom of the support rod is slidably connected to the moving groove. The clamping mechanism also includes a clamping base plate, a return spring, a first electromagnetic block, a second electromagnetic block, and clamping side plates. The clamping side plates are firmly connected to the support rod. There are two first electromagnetic blocks, and the two first electromagnetic blocks are respectively placed at both ends of the clamping base plate. There are two second electromagnetic blocks and two clamping side plates. Two adjusting grooves are provided on the surface of the clamping base plate. The two clamping side plates are slidably connected to the clamping base plate, and the two clamping side plates are respectively slidably connected to the two adjusting grooves. A second electromagnetic block is firmly connected to the side of the clamping side plate close to the first electromagnetic block. There are two return springs, and the two return springs are respectively placed at the top and bottom of the clamping side plates. The top and bottom of the two clamping side plates are both firmly connected to the return springs. Rubber is covered on the sides of the two clamping side plates close to each other; In the normal state: After the first electromagnetic block and the second electromagnetic block are energized, they fit together, and the return spring is stretched; In the clamping state: After the first electromagnetic block and the second electromagnetic block are powered off, they separate, and the return spring contracts.

[0010] In the clamping mechanism, which is used to clamp the pump body, a pushing hydraulic cylinder is placed in the moving groove. The output end of the pushing hydraulic cylinder is firmly connected to the support rod. The pushing hydraulic cylinder can push the support rod to slide in the moving groove. The support rod is firmly connected to the clamping bottom plate. During the process of the support rod being driven to move, it will drive the clamping bottom plate to move together. On the left and right sides of the clamping bottom plate, first electromagnetic blocks are firmly connected respectively. On the clamping bottom plate, two clamping side plates are also slidably connected. On the side of the clamping side plate close to the first electromagnetic block, a second electromagnetic block is firmly connected. A reset spring is arranged between the two clamping side plates. In the initial state, the first electromagnetic block and the second electromagnetic block are energized and magnetized, and the adjacent first electromagnetic block and second electromagnetic block are tightly adsorbed together, and the reset spring is stretched. At this time, the distance between the two clamping side plates is the largest. After the pump body that needs to have its casting waste cut is placed between the two clamping side plates, the first electromagnetic block and the second electromagnetic block are de-energized. At this time, the reset spring contracts, and the two clamping side plates approach each other. Rubber is covered on the side of the two clamping side plates that approaches each other. After the two clamping side plates are in contact with the pump body, they stop moving. At this time, it is not the shortest length that the reset spring can contract to. Therefore, the reset spring still maintains the tendency to contract, making the two clamping side plates fit tightly with the pump body and unable to move, so as to fix the pump body. After operations such as casting port cutting are completed, power is reconnected, the first electromagnetic block and the second electromagnetic block are adsorbed together again, the reset spring is stretched, and the two clamping side plates move away from each other. After that, the pump body can be taken out.

[0011] Further, the cutting mechanism includes a first driving hydraulic cylinder, a driving platform, and a second driving hydraulic cylinder. The fixed end of the first driving hydraulic cylinder is firmly connected to the fixed bottom plate. The output end of the first driving hydraulic cylinder is firmly connected to the driving platform. A driving groove is provided on the driving platform. The second driving hydraulic cylinder is firmly connected to the driving platform, and the fixed end of the second driving hydraulic cylinder is firmly connected to the side wall of the driving groove. The cutting mechanism also includes a rough cutting tool, a first driving motor, a fine cutting tool, a second driving motor, a driving connecting rod, and an infrared sensor. A protrusion is provided in the middle of the driving connecting rod. The driving connecting rod is slidably connected to the driving platform. The protrusion of the driving connecting rod is placed in the driving groove, and the protrusion of the driving connecting rod is slidably connected to the driving groove. The output end of the second driving hydraulic cylinder is firmly connected to the protrusion of the driving connecting rod. The bottom of the driving connecting rod is firmly connected to the first driving motor. The part of the driving connecting rod close to the top is firmly connected to the second driving motor. The output end of the first driving motor is firmly connected to the rough cutting tool. The output end of the second driving motor is firmly connected to the fine cutting tool. The distance between the rough cutting tool and the fine cutting tool is greater than the diameter of the casting port of the pump body. The top of the driving connecting rod is firmly connected to the infrared sensor, and the detection end of the infrared sensor faces the fixed bottom plate.

[0012] In the cutting mechanism, the mechanism is used to cut the casting opening of the pump body and remove the excess material during the casting process. The rough cutting tool and the fine cutting tool perform double cutting on the casting opening of the pump body to improve the cutting accuracy. The rough cutting tool and the fine cutting tool are respectively placed at the upper and lower ends of the driving connecting rod. The driving connecting rod is firmly connected to the second driving hydraulic cylinder, and the second driving hydraulic cylinder is firmly connected to the side wall of the driving groove. After the second driving hydraulic cylinder is started, it can drive the driving connecting rod to move left and right. The first driving motor and the second driving motor are firmly connected to the driving connecting rod, driving the rough cutting tool and the fine cutting tool to rotate and cut respectively. By the second driving hydraulic cylinder, the driving connecting rod moves left and right, realizing the left and right displacement of the rough cutting tool and the fine cutting tool during the cutting process, rather than directly cutting straight up and down. This can make the cutting edge smooth, with less resistance on the tool during the cutting process, and can efficiently complete the cutting. After the device is started, the infrared sensor detects the distance between the tool and the casting opening to be cut, and the pushing hydraulic cylinder adjusts the distance between the casting opening of the pump body and the tool. The distance between the rough cutting tool and the fine cutting tool is greater than the diameter of the casting opening of the pump body, so there is no contact with the casting opening of the pump body in the initial state. First, rough cutting is performed on the casting opening of the pump body. Rough cutting is performed at a certain length from the position to be cut, and most of the waste materials are removed first. The first driving motor is started, and the rough cutting tool rotates rapidly. At the same time, the first driving hydraulic cylinder and the second driving hydraulic cylinder are started. The first driving hydraulic cylinder extends to make the rough cutting tool move towards the casting opening of the pump body for cutting. The second driving hydraulic cylinder repeatedly extends and retracts to realize the left and right moving cutting of the rough cutting tool. After the rough cutting is completed, the first driving hydraulic cylinder resets, and the second driving hydraulic cylinder stops starting for fine cutting. The infrared sensor detects the distance, and the pushing hydraulic cylinder pushes the casting opening of the pump body to the corresponding position. At this time, the pushing hydraulic cylinder extends to the maximum. The second driving motor is started, and the first driving hydraulic cylinder gradually retracts, making the fine cutting tool gradually contact the casting opening of the pump body. The second driving hydraulic cylinder is started to realize the left and right moving cutting of the fine cutting tool, thereby completing the fine cutting of the casting opening of the pump body. After completion, the pushing hydraulic cylinder retracts by half to prevent the tool from wearing the cutting surface when resetting, and then the cutting mechanism resets.

[0013] Further, the notch grinding mechanism includes a moving device. The moving device is connected to the fixed bottom plate and the side baffle. The moving device includes a lifting hydraulic cylinder, a servo motor, a rotating shaft rod, a driven block, and a telescopic rod. The fixed end of the lifting hydraulic cylinder is tightly connected to the fixed bottom plate. The bottom of the servo motor is tightly connected to the output end of the lifting hydraulic cylinder. The servo motor is in close contact with one side baffle. The output end of the servo motor is tightly connected to the rotating shaft rod. The end of the rotating shaft rod away from the servo motor is rotatably connected to the telescopic rod. The telescopic rod is in contact with the other side baffle. The bottom of the telescopic rod is tightly connected to the fixed bottom plate. The rotating shaft rod is provided with threads. The driven block is provided with a through hole. The inner wall of the through hole of the driven block is provided with threads. The rotating shaft rod and the driven block are connected by threads. The moving device is connected to the defect marking mechanism. The driven block is connected to the defect marking mechanism. The notch grinding mechanism further includes a grinding device. The grinding device is connected to the moving device and the driven block. The grinding device includes a grinding wheel and a third driving motor. The third driving motor is tightly connected to the driven block. The output end of the third driving motor is tightly connected to the grinding wheel.

[0014] In the notch grinding mechanism, this mechanism is used to grind the cutting surface of the pump body casting port after double cutting, and grind off impurities such as burrs that may be generated during the cutting process. The notch grinding mechanism is placed at a position where the pushing hydraulic cylinder retracts by half. After the pump body casting port is cut twice, the pushing hydraulic cylinder retracts by half. While preventing the tool from resetting and causing wear to the cutting surface, it also facilitates grinding. The moving device drives the grinding device to move. The grinding device is tightly connected to the driven block. When the servo motor drives the rotating shaft rod to move, the driven block moves along the rotating shaft rod, thereby driving the grinding device to move. When the grinding device moves along the rotating shaft rod, the lifting hydraulic cylinder and the telescopic rod enable the rotating shaft rod to move up and down, so as to achieve full grinding of the pump body casting port by the grinding device. The third driving motor drives the grinding wheel to grind the cutting surface of the pump body casting port, removing impurities such as burrs generated by cutting.

[0015] Further, the defect marking mechanism includes a fixing plate and detection electric needles. The fixing plate is tightly connected to the driven block. There are two detection electric needles. The two detection electric needles are tightly connected to the fixing plate. Wires are connected to the two detection electric needles. The detection electric needles face the pump body casting port.

[0016] In the defect marking mechanism, which is used to detect defects on the cutting surface of the pump body casting orifice, since the pump body is cast, after casting, the orifice may have uneven cooling, resulting in possible holes or cracks inside. Detecting the cutting surface after cutting can facilitate subsequent timely repair. The defect marking mechanism is firmly connected to the driven block. After the grinding device finishes grinding, it can immediately detect the ground area and provide timely feedback. The detection electric needle is used to perform dot detection on the cutting surface. When a crack or depression is detected, the distance from the detection electric needle to the corresponding position changes, resulting in a change in the potential difference, that is, a change in voltage, to mark the defective area.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: After the present invention is started, the clamping mechanism clamps the pump body. The first electromagnetic block and the second electromagnetic block are powered off, and the return spring contracts. The two clamping side plates move closer to clamp the pump body. Then, double cutting is performed on the casting orifice of the pump body. The infrared sensor detects the distance between the cutting tool and the casting orifice to be cut, and the pushing hydraulic cylinder is used to adjust the distance between the pump body casting orifice and the cutting tool. First, rough cutting is performed on a place at a certain length from the cutting position to remove most of the waste. Through the extension and the extension and retraction of the second driving hydraulic cylinder of the first driving hydraulic cylinder, when the rough cutting tool cuts upward the casting orifice, it moves left and right for cutting, and after completion, the hydraulic cylinder resets; then fine cutting is performed. The infrared sensor detects the distance, and the pushing hydraulic cylinder pushes the pump body casting orifice to the corresponding position. At this time, the pushing hydraulic cylinder extends to the maximum length. Through the shortening of the first driving hydraulic cylinder and the extension and retraction of the second driving hydraulic cylinder, when the fine cutting tool cuts downward the casting orifice, it moves left and right for cutting. After completion, the pushing hydraulic cylinder retracts by half to prevent the cutting surface from being worn when the cutting tool resets. Then, the cutting mechanism resets, and the moving device drives the grinding device to move. The rotating shaft rod is rotated by starting the servo motor, so that the driven block moves along the rotating shaft rod, thereby realizing grinding and cutting of the casting orifice at the same height. Driven by the lifting hydraulic cylinder, the moving device is driven to move up and down, thereby realizing grinding and cutting of the casting orifice on the same vertical line. The combination of the two realizes sufficient grinding and cutting of the cutting surface of the casting orifice. The defect marking mechanism is firmly connected to the driven block. During the movement of the grinding device, the defect marking mechanism will move along with it and can immediately detect the ground area. When no crack or depression is detected, the distance from the detection electric needle to the corresponding position does not change, and the potential difference does not change; when a crack or depression is detected, the distance from the detection electric needle to the corresponding position changes, resulting in a change in the potential difference, that is, a change in voltage, and timely feedback is provided to mark the defective area. After completion, the pushing hydraulic cylinder retracts to the shortest length, and power is restored. The first electromagnetic block and the second electromagnetic block are adsorbed together again, the return spring is stretched, and the two clamping side plates move away from each other. Then, the pump body can be taken out. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Embodiment: As Figures 1-9As shown in the figure, the present invention provides a technical solution for a pump body casting port cutting device with an adaptive clamping function. The cutting device cuts the casting port of the pump body. The cutting device includes a fixing mechanism 1, a clamping mechanism 2, a cutting mechanism 3, a cut surface grinding mechanism 4, and a defect marking mechanism 5. The fixing mechanism 1 is connected to the clamping mechanism 2, the fixing mechanism 1 is connected to the cutting mechanism 3, the fixing mechanism 1 is connected to the cut surface grinding mechanism 4, and the cut surface grinding mechanism 4 is connected to the defect marking mechanism 5.

[0022] In the present invention, the fixing mechanism 1 is used to fix other mechanisms and provide a support for other mechanisms. The clamping mechanism 2 is used to clamp and fix the pump body that needs to be cut at the casting port to prevent the pump body from moving during the casting port cutting process, which may affect the cutting. The cutting mechanism 3 is used to cut the casting port of the pump body and remove the excess waste after casting to facilitate subsequent use. The cut surface grinding mechanism 4 is used to grind the cut surface of the pump body after cutting and remove burrs and the like generated by cutting. The defect marking mechanism 5 is used to detect cracks and depressions on the cut surface after grinding to prevent internal cracks and depressions from occurring due to uneven cooling of the pump body after casting and being revealed after the casting port cutting.

[0023] The fixing mechanism 1 includes a fixing bottom plate 11 and side baffles 12. There are three side baffles 12. The fixing bottom plate 11 and the side baffles 12 are firmly connected. A moving groove 111 is provided on the fixing bottom plate 11. The fixing bottom plate 11 is connected to the clamping mechanism 2, the moving groove 111 is connected to the clamping mechanism 2, the fixing bottom plate 11 is connected to the cutting mechanism 3, the fixing bottom plate 11 is connected to the cut surface grinding mechanism 4, and the side baffles 12 are connected to the cut surface grinding mechanism 4.

[0024] In the fixing mechanism 1, this mechanism is used to provide support for other mechanisms of the cutting device. The fixing bottom plate 11 is used to support other mechanisms and provide a place for the mechanisms to operate. There are three side baffles 12. The three side baffles 12 surround three sides of the fixing bottom plate 11. There is no side baffle 12 on the side close to the back of the clamping mechanism 2. The three side baffles 12 mainly fix the bottom plate 11 and can also block the flying debris that may occur during subsequent cutting and grinding to a certain extent, so that it can only fall on the fixing bottom plate 11, which is convenient for subsequent cleaning.

[0025] The clamping mechanism 2 further includes a clamping base plate 23, a return spring 24, a first electromagnet 25, a second electromagnet 26, and clamping side plates 27. The clamping side plates 27 are fixedly connected to the support rod 22. There are two first electromagnets 25, and the two first electromagnets 25 are respectively placed at both ends of the clamping base plate 23. There are two second electromagnets 26 and two clamping side plates 27. Two adjusting grooves 231 are provided on the surface of the clamping base plate 23. The two clamping side plates 27 are slidably connected to the clamping base plate 23, and the two clamping side plates 27 are respectively slidably connected to the two adjusting grooves 231. A second electromagnet 26 is fixedly connected to the side of the clamping side plate 27 close to the first electromagnet 25. There are two return springs 24, and the two return springs 24 are respectively placed at the top and bottom of the clamping side plates 27. The top and bottom of the two clamping side plates 27 are fixedly connected with return springs 24. Rubber is covered on the adjacent surfaces of the two clamping side plates 27; Under normal conditions: After the first electromagnet 25 and the second electromagnet 26 are energized, they are attached, and the return spring 24 is stretched; In the clamping state: After the first electromagnet 25 and the second electromagnet 26 are powered off, they are separated, and the return spring 24 contracts.

[0026] In the clamping mechanism 2, this mechanism is used to clamp the pump body. The pushing hydraulic cylinder 21 is placed in the moving groove 111. The output end of the pushing hydraulic cylinder 21 is fixedly connected to the support rod 22. The pushing hydraulic cylinder 21 can push the support rod 22 to slide in the moving groove 111. The support rod 22 is fixedly connected to the clamping base plate 23. During the process of the support rod 22 being driven to move, it will drive the clamping base plate 23 to move together. The first electromagnets 25 are respectively fixedly connected to the left and right sides of the clamping base plate 23. Two clamping side plates 27 are also slidably connected to the clamping base plate 23. A second electromagnet 26 is fixedly connected to the side of the clamping side plate 27 close to the first electromagnet 25. A return spring 24 is provided between the two clamping side plates 27. In the initial state, the first electromagnet 25 and the second electromagnet 26 are energized and magnetic, and the adjacent first electromagnet 25 and second electromagnet 26 are tightly adsorbed together, and the return spring 24 is stretched. At this time, the distance between the two clamping side plates 27 is the largest; after the pump body that needs to cut the sprue waste is placed between the two clamping side plates 27, the first electromagnet 25 and the second electromagnet 26 are powered off. At this time, the return spring 24 contracts, and the two clamping side plates 27 approach each other. Rubber is covered on the adjacent sides of the two clamping side plates 27. After the two clamping side plates 27 are attached to the pump body, they stop moving. At this time, it is not the shortest length that the return spring 24 can contract to. Therefore, the return spring 24 still maintains the tendency to contract, making the two clamping side plates 27 tightly attached to the pump body and unable to move, so as to fix the pump body. After completing operations such as sprue cutting, power on again, the first electromagnet 25 and the second electromagnet 26 are adsorbed together again, the return spring 24 is stretched, and the two clamping side plates 27 move away from each other. After that, the pump body can be taken out.

[0027] The cutting mechanism 3 includes a first driving hydraulic cylinder 31, a driving platform 32, and a second driving hydraulic cylinder 33. The fixed end of the first driving hydraulic cylinder 31 is firmly connected to the fixed bottom plate 11.

The second driving hydraulic cylinder 33 is firmly connected to the driving platform 32, and the fixed end of the second driving hydraulic cylinder 33 is firmly connected to the side wall of the driving groove 321. The cutting mechanism 3 further includes a rough cutting tool 34, a first driving motor 35, a fine cutting tool 36, a second driving motor 37, a driving connecting rod 38, and an infrared sensor. A protrusion is provided in the middle of the driving connecting rod 38. The driving connecting rod 38 is slidably connected to the driving platform 32. The protrusion of the driving connecting rod 38 is placed in the driving groove 321, and the protrusion of the driving connecting rod 38 is slidably connected to the driving groove 321. The output end of the second driving hydraulic cylinder 33 is firmly connected to the protrusion of the driving connecting rod 38. The bottom of the driving connecting rod 38 is firmly connected to the first driving motor 35. The second driving motor 37 is firmly connected to the driving connecting rod 38 near the top. The output end of the first driving motor 35 is firmly connected to the rough cutting tool 34. The output end of the second driving motor 37 is firmly connected to the fine cutting tool 36.

The top of the driving connecting rod 38 is firmly connected to the infrared sensor, and the detection end of the infrared sensor faces the fixed bottom plate 11.

[0028] In the cutting mechanism 3, this mechanism is used to cut the casting opening of the pump body, removing the excess material during the casting process. The rough cutting tool 34 and the fine cutting tool 36 perform double cutting on the casting opening of the pump body to improve the cutting accuracy. The rough cutting tool 34 and the fine cutting tool 36 are respectively placed at the upper and lower ends of the driving connecting rod 38. The driving connecting rod 38 is fixedly connected to the second driving hydraulic cylinder 33, and the second driving hydraulic cylinder 33 is fixedly connected to the side wall of the driving groove 321. After the second driving hydraulic cylinder 33 is started, it can drive the driving connecting rod 38 to move left and right. The first driving motor 35 and the second driving motor 37 are fixedly connected to the driving connecting rod 38, respectively driving the rough cutting tool 34 and the fine cutting tool 36 to rotate and cut. By the second driving hydraulic cylinder 33, the driving connecting rod 38 moves left and right, enabling the rough cutting tool 34 and the fine cutting tool 36 to have a left-right displacement during the cutting process instead of a direct up-and-down cutting. This can make the cutting edge smooth, with less resistance on the cutting tool during the cutting process, and can efficiently complete the cutting. After the device is started, the infrared sensor detects the distance between the cutting tool and the casting opening to be cut, and the pushing hydraulic cylinder 21 adjusts the distance between the casting opening of the pump body and the cutting tool. The distance between the rough cutting tool 34 and the fine cutting tool 36 is greater than the diameter of the casting opening of the pump body, so there is no contact with the casting opening of the pump body in the initial state. First, rough cutting is performed on the casting opening of the pump body. Rough cutting is carried out at a certain length from the position to be cut, first removing most of the waste material. The first driving motor 35 is started, and the rough cutting tool 34 rotates rapidly. At the same time, the first driving hydraulic cylinder 31 and the second driving hydraulic cylinder 33 are started. The first driving hydraulic cylinder 31 extends to make the rough cutting tool 34 move towards the casting opening of the pump body for cutting, and the second driving hydraulic cylinder 33 repeatedly extends and retracts to achieve the left-right moving cutting of the rough cutting tool 34. After the rough cutting is completed, the first driving hydraulic cylinder 31 resets, and the second driving hydraulic cylinder 33 stops starting for fine cutting. The infrared sensor detects the distance, and the pushing hydraulic cylinder 21 pushes the casting opening of the pump body to the corresponding position. At this time, the pushing hydraulic cylinder 21 extends to the maximum. The second driving motor 37 is started, and the first driving hydraulic cylinder 31 gradually retracts, making the fine cutting tool 36 gradually contact the casting opening of the pump body. The second driving hydraulic cylinder 33 is started to achieve the left-right moving cutting of the fine cutting tool 36, thereby completing the fine cutting of the casting opening of the pump body. After completion, the pushing hydraulic cylinder 21 retracts by half to prevent the cutting surface from being worn when the cutting tool resets. Then the cutting mechanism 3 resets.

The moving device 41 includes a lifting hydraulic cylinder 411, a servo motor 412, a rotating shaft rod 413, a driven block 414 and a telescopic rod. The fixed end of the lifting hydraulic cylinder 411 is fixedly connected to the fixed bottom plate 11. The bottom of the servo motor 412 is fixedly connected to the output end of the lifting hydraulic cylinder 411. The servo motor 412 is in close contact with one side baffle 12. The output end of the servo motor 412 is fixedly connected to the rotating shaft rod 413. One end of the rotating shaft rod 413 away from the servo motor 412 is rotatably connected to the telescopic rod. The telescopic rod is in contact with the other side baffle 12. The bottom of the telescopic rod is fixedly connected to the fixed bottom plate 11. The rotating shaft rod 413 is provided with threads. The driven block 414 is provided with a through hole. The inner wall of the through hole of the driven block 414 is provided with threads. The rotating shaft rod 413 and the driven block 414 are connected by threads. The moving device 41 is connected to the defect marking mechanism 5. The driven block 414 is connected to the defect marking mechanism 5. The notch grinding mechanism 4 further includes a grinding device 42. The grinding device 42 is connected to the moving device 41 and the driven block 414. The grinding device 42 includes a grinding wheel 421 and a third driving motor 422. The third driving motor 422 is fixedly connected to the driven block 414. The output end of the third driving motor 422 is fixedly connected to the grinding wheel 421.

[0030] In the notch grinding mechanism 4, this mechanism is used to grind the cutting surface of the pump body casting port after double cutting, and remove impurities such as burrs that may be generated during the cutting process. The notch grinding mechanism 4 is placed at a position where the pushing hydraulic cylinder 21 retracts by half. After the pump body casting port is cut twice, the pushing hydraulic cylinder 21 retracts by half, which not only prevents the tool from resetting and causing wear to the cutting surface, but also facilitates grinding. The moving device 41 drives the grinding device 42 to move. The grinding device 42 is fixedly connected to the driven block 414. When the servo motor 412 drives the rotating shaft rod 413 to move, the driven block 414 moves along the rotating shaft rod 413, thereby driving the grinding device 42 to move. When the grinding device 42 moves along the rotating shaft rod 413, the lifting hydraulic cylinder 411 and the telescopic rod enable the rotating shaft rod 413 to move up and down, so as to realize the full grinding of the pump body casting port by the grinding device 42. The grinding wheel 421 is driven by the third driving motor 422 to grind the cutting surface of the pump body casting port, and remove impurities such as burrs generated by cutting.

[0031] The defect marking mechanism 5 includes a fixing plate 51 and a detection electric needle 52. The fixing plate 51 is fixedly connected to the driven block 414. There are two detection electric needles 52. The two detection electric needles 52 are fixedly connected to the fixing plate 51. Wires are connected to the two detection electric needles 52. The detection electric needles 52 face the pump body casting port.

[0032] In the defect marking mechanism 5, which is used to detect defects on the cutting surface of the pump body casting port. Since the pump body is cast, after casting, due to uneven cooling at the casting port, there may be holes or cracks inside. Detecting the cutting surface after cutting can facilitate timely repair in the follow-up. The defect marking mechanism 5 is firmly connected to the driven block 414. After the grinding device 42 finishes grinding, it can immediately detect the ground area and provide timely feedback. The cutting surface is detected by the detection electric needle 52 by dotting. When cracks or depressions are detected, the distance from the detection electric needle 52 to the corresponding position will change, resulting in a change in the potential difference, that is, a change in voltage, so as to mark the defective area.

[0033] Working principle of the present invention: After the present invention is started, the clamping mechanism 2 clamps the pump body. The first electromagnet 25 and the second electromagnet 26 are powered off, and the return spring 24 contracts. The two clamping side plates 27 approach each other to clamp the pump body. Then, double cutting is performed at the casting port of the pump body. The infrared sensor detects the distance between the tool and the casting port to be cut, and pushes the hydraulic cylinder 21 to adjust the distance between the casting port of the pump body and the tool. First, rough cutting is performed at a certain length from the cutting position to remove most of the waste materials. Through the extension of the first driving hydraulic cylinder 31 and the extension and retraction of the second driving hydraulic cylinder 33, when the rough cutting tool 34 cuts upward at the casting port, it moves left and right for cutting. After completion, the hydraulic cylinder resets; then, fine cutting is performed. The infrared sensor detects the distance and pushes the hydraulic cylinder 21 to push the casting port of the pump body to the corresponding position. At this time, the pushing hydraulic cylinder 21 extends to the maximum length. Through the shortening of the first driving hydraulic cylinder 31 and the extension and retraction of the second driving hydraulic cylinder 33, when the fine cutting tool 36 cuts downward at the casting port, it moves left and right for cutting. After completion, the pushing hydraulic cylinder 21 retracts by half to prevent the tool from wearing the cutting surface when resetting. Then, the cutting mechanism 3 resets. The moving device 41 drives the grinding device 42 to move. By starting the servo motor 412 to rotate the rotating shaft rod 413, the driven block 414 moves along the rotating shaft rod 413, thereby realizing grinding and cutting at the casting port at the same height. Driven by the lifting hydraulic cylinder 411, the moving device 41 is driven to move up and down, thereby realizing grinding and cutting at the casting ports on the same vertical line. The combination of the two realizes sufficient grinding of the cutting surface of the casting port. The defect marking mechanism 5 is firmly connected to the driven block 414. During the movement of the grinding device 42, the defect marking mechanism 5 will move along with it and can immediately detect the ground area. When no cracks or depressions are detected, the distance between the detection electric needle 52 and the corresponding position does not change, and the potential difference does not change; when cracks or depressions are detected, the distance between the detection electric needle 52 and the corresponding position changes, resulting in a change in the potential difference, that is, the voltage changes, and timely feedback is provided to mark the defective area. After completion, the pushing hydraulic cylinder 21 retracts to the shortest, and the power is restored. The first electromagnet 25 and the second electromagnet 26 are adsorbed together again. The return spring 24 is stretched, and the two clamping side plates 27 move away from each other. Then, the pump body can be taken out.
