Description

Technical Field

[0001] The present invention relates to the technical field of part trimming, and more specifically, to an automatic trimming machine for casting parts. Background Art

[0002] In modern manufacturing, casting is a widely used metal forming process. By injecting liquid metal into a mold and cooling it to solidify, the desired part shape is formed. And with the continuous development of the casting field, in order to deal with the excess materials generated at the edge cutting points during part casting, such as flash, burrs, and irregular surfaces, an automatic trimming machine is configured to work with the casting end to ensure that the parts meet the design requirements and quality standards.

[0003] The existing automatic trimming machines on the market usually work by mechanical cutting. Specifically, the part is placed in a fixed fixture, and its position is ensured to be accurate through a high-precision positioning system. Subsequently, the part in the fixture is subjected to full-automatic servo trimming by a high-speed rotating blade, and then the surface of the part is subjected to secondary treatment by means of mechanical scraping, grinding, or polishing to remove the remaining burrs. At the same time, in order to further optimize the quality of the part cutting surface, some devices are also equipped with an intelligent control system that can automatically adjust the deburring parameters according to the material and shape of the part to ensure the best processing effect.

[0004] However, in the actual operation process, the automatic trimming machine can still make the cutting surface meet the existing requirements and quality standards for ordinary square parts. But when casting tubular parts, due to the particularity of the cutting surface, flash burrs will be generated simultaneously on the inner wall edge, outer wall edge, and cutting surface of the tube during the cutting process. And the mechanical scraping mechanism configured in the existing trimming machine cannot optimize the treatment of these three end faces at the same time. The existing treatment solutions either control the scraping end to process at multiple angles in multiple times through the intelligent control system, or use electrolytic reaction to dissolve the impurities on the part cutting surface, which is not only time-consuming and laborious, but also makes the casting production line become cumbersome and difficult to control. Summary of the Invention

[0013] As a further solution of the present invention: the cross-section scraping mechanism also includes an air filling chamber opened at the middle position of the inner cavity of the cavity shell, the linked outward extension rods are all sealed and penetrated into the air filling chamber from the top of the cavity shell, and a first piston sleeve is fixedly installed on the insertion end, a sealing ring that fits the inner wall of the air filling chamber is fixedly installed on the outer edge of the first piston sleeve, and a second pointed scraper block is fixedly installed on the outer side of the outer top sleeve.

[0014] As a further solution of the present invention: storage boxes are fixedly installed on both side edges of the cavity shell, and two inflation ducts extending outward from the interior of the inflation bin are fixedly installed at the middle position on the other side of the cavity shell away from the second pointed scraper block, and the extended ends of the inflation ducts are connected to the storage boxes on the same side, and a second ventilation slot for connecting the inflation duct with the interior of the storage box is opened on the inner side surface of the storage box on each side, and a second piston sleeve is slidably installed inside the storage box on each side.

Second reserved slots for embedding the inflation conduits are provided at the middle positions of the surfaces of the platform partitions, and one-way valve covers are hingedly installed at the corner positions near the inflation chambers inside each inflation conduit.

[0017] Compared with the prior art, the above technical solution provided by the present invention has at least the following beneficial effects: (1) Through the cutting surface scraping mechanism, the problem in the prior art of being unable to simultaneously process the burrs on the inner wall edge, outer wall edge and cutting surface of the conduit is solved. Through the coordinated operation of the first multi-stage adjustment module and the second multi-stage adjustment module, the high-speed cutting module and the cutting surface scraping mechanism can be flexibly switched, and their positions and angles can be accurately controlled. In particular, the U-shaped scraping structure in the cutting surface scraping mechanism, which is composed of the first pointed nozzle scraping block and the second pointed nozzle scraping blocks on both sides, can be simultaneously attached to the outer surface, inner circular wall and cutting surface of the conduit, realizing the synchronous optimization processing of the three end faces. This not only improves the production efficiency, but also ensures the consistency and stability of the cutting edge quality, avoiding the error accumulation caused by multiple treatments in the traditional method.

[0018] (2) Through the servo control system, high-precision control of the cutting and scraping processes is achieved. Driven by the servo motors of the first multi-stage adjustment module and the second multi-stage adjustment module, the device can automatically adjust the cutting and scraping angles and distances according to different sizes and shapes of conduits, adapting to the processing requirements of various types of parts. In addition, the introduction of the third servo motor enables the cutting surface scraping mechanism to continuously adjust the distance between the second pointed nozzle scraping blocks on both sides during rotation, ensuring that it always closely adheres to the surface of the conduit and providing uniform scraping force. This not only improves the flexibility and adaptability of the device, but also reduces the need for manual intervention, lowers the operation difficulty and human error. More importantly, the entire cutting edge process can be automatically completed through a preset program, further enhancing the automation level of the production line, saving labor costs and improving production efficiency.

[0019] (3) By introducing an auxiliary reagent spraying system during the edge trimming process, the edge trimming effect is improved. Through the built-in lifting and inflating module and atomizing nozzles, the device can spray metal multi-functional reagents in real time during the scraping process. These reagents contain lubricants, abrasive particles, and polishing components, and can complete deburring, grinding, and polishing in one operation, further improving the quality of the cut surface. Especially when processing high-hardness or burr-prone materials, the use of auxiliary reagents can effectively reduce tool wear, extend tool life, and at the same time improve the smoothness and accuracy of the cut surface. In addition, the introduction of the servo fan not only enhances the air-cooling effect during the scraping process, but also removes static electricity on the catheter cut surface by blowing air, optimizing the overall effect of the cut surface treatment. It not only improves the edge trimming effect, but also increases the versatility of the device, is suitable for processing more types of metal parts, and meets the requirements of different application scenarios.

[0024] The following describes in detail an automatic edge trimming machine for casting parts provided by the present invention in conjunction with the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some well-known technical fields, those skilled in the art can also implement them in other alternative ways; moreover, the accompanying drawings are only for more specifically describing the embodiments and are not intended to specifically limit the present invention.

[0025] As Figures 1 to 9 shown, an embodiment of the present invention provides an automatic edge trimming machine for casting parts, including a chassis cabinet 1. A support member is configured on one side of the inner wall of the chassis cabinet 1, and a first multi-stage adjustment module 2 is installed through the support member. A part fastening crane 5 is fixedly installed on the other side of the inner wall of the chassis cabinet 1, and a chip receiving box 6 is placed at the position directly below the part fastening crane 5. A high-speed cutting module 3 is configured on one side of the output end of the first multi-stage adjustment module 2, and a second multi-stage adjustment module 4 is configured on the other side. A cutting surface scraping mechanism 7 is configured on the output end of the second multi-stage adjustment module 4; The high-speed cutting module 3 and the cutting surface scraping mechanism 7 reciprocate and extend to one side of the part fastening crane 5 through the rotation of the output end of the first multi-stage adjustment module 2, and automatically trim the conduits clamped on the part fastening crane 5 in sequence. Among them, the second multi-stage adjustment module 4 further includes a first pointed nozzle scraping block 43, and also includes platform partitions 72 sleeved on both sides of the first pointed nozzle scraping block 43. At the position of each side of the platform partition 72 facing the midpoint end of the first pointed nozzle scraping block 43, a jacking inflation module 711 is arranged. The reset end of the jacking inflation module 711 is provided with a second pointed nozzle scraping block 712. The first pointed nozzle scraping block 43 and the second pointed nozzle scraping blocks 712 on both sides together form a U-shaped scraping structure to simultaneously remove the impurities on the side surfaces of the three ends of the conduit.

[0026] To solve the problem that the existing automatic edge trimming machine cannot optimize the burrs on the inner wall edge, outer wall edge and cutting surface of the casting conduit-shaped parts at the same time, making the casting production line cumbersome and difficult to control, the above technical solution is adopted to solve the problem. The above technical solution mainly consists of a chassis cabinet 1, a first multi-stage adjustment module 2, a high-speed cutting module 3, a second multi-stage adjustment module 4, a part fastening crane 5, a chip receiving box 6 and a cutting surface scraping mechanism 7. Among them, the chassis cabinet 1 is a conventional cabinet in the prior art, equipped with an outward-turning visible explosion-proof door for conveniently observing the internal working conditions in real time. The first multi-stage adjustment module 2 and the second multi-stage adjustment module 4 are both servo adjustment structures for changing the left and right angles and distances of the device to facilitate close fitting of conduits of more size types. The high-speed cutting module 3 is a high-speed automatic cutting tool group module for cutting conduits in the prior art, controlled by a high-speed motor, and performs multi-angle full-automatic cutting through the tool head at the output end to make the outer side surface of the conduit cut flat. The part fastening crane 5 is a robotic arm structure with multi-axis servo control in the prior art for clamping the conduit parts to be cut. The chip receiving box 6 arranged at its bottom is used to receive the part debris falling from the cutting surface during the cutting process. The second multi-stage adjustment module 4 further includes a first pointed nozzle scraping block 43, and the configured cutting surface scraping mechanism 7 further includes platform partitions 72 sleeved on both sides of the first pointed nozzle scraping block 43, a jacking inflation module 711 and a second pointed nozzle scraping block 712. Among them, the first pointed nozzle scraping block 43 and the second pointed nozzle scraping blocks 712 on both sides are attached together to form a U-shaped scraping structure, which can be sleeved on the cutting surface of the conduit to simultaneously remove the impurities on the side surfaces of the three ends of the conduit, solving the problem that the existing automatic edge trimming machine cannot optimize the burrs on the inner wall edge, outer wall edge and cutting surface of the casting conduit-shaped parts at the same time, making the casting production line cumbersome and difficult to control.

[0027] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown in Figure 9 , the first multi-stage adjustment module 2 includes a first servo motor 21. The output end of the first servo motor 21 extends in a direction perpendicular to the side wall of the chassis cabinet 1, and a second servo motor 22 is fixedly connected to the extended end. The output end of the second servo motor 22 extends in a direction parallel to the side wall of the chassis cabinet 1, and a double-sided turntable 23 is fixedly connected to the extended end. The two sides of the double-sided turntable 23 extend equidistantly to both sides at a horizontal angle of 180 degrees, and an electric servo telescopic rod 24 is fixedly installed on each side of the extended end. The telescopic direction of the electric servo telescopic rod 24 is parallel to the side wall of the chassis cabinet 1. A high-speed cutting module 3 is fixedly installed on the telescopic end of one side of the electric servo telescopic rod 24, and a second multi-stage adjustment module 4 is fixedly installed on the telescopic end of the electric servo telescopic rod 24 on the other side.

[0028] Among them, the first servo motor 21 and the second servo motor 22 configured in the configured first multi-stage adjustment module 2 are both motors capable of servo control in the prior art. And the output end of the first servo motor 21 is a telescopic rod structure that can be electrically controlled in the prior art, which is the same as the configured electric servo telescopic rod 24 structure, used to control the horizontal extension and retraction of the output end. The configured electric servo telescopic rod 24 is also a telescopic rod structure of a motor capable of servo control in the prior art. The adjustment module constituted by it is used on the one hand to adjust the switching state between the high-speed cutting module 3 and the cutting surface scraping mechanism 7, and on the other hand to drive the high-speed cutting module 3 and the cutting surface scraping mechanism 7 to perform circular rotation. The specific working principle is as follows: First, open the chassis cabinet 1, fix the conduit part with the part fastening crane 5, and align the center of the conduit part with the axis of the output end of the first servo motor 21; Then, control the double-sided turntable 23 to perform a 180-degree servo rotation through the output end of the second servo motor 22, and rotate one end of the high-speed cutting module 3 to face one end of the part fastening crane 5 to cut the conduit clamped on the part fastening crane 5; Then, the output end of the second servo motor 22 is used to control the bilateral turntable 23 to perform a 180-degree servo rotation. The output end of the second servo motor 22 controls the bilateral turntable 23 to perform a 180-degree servo rotation, and rotates one end of the second multi-stage adjustment module 4 to face one end of the part fastening crane 5, so as to further process the cross-section of the conduit clamped on the part fastening crane 5. Through the telescopic action of the electric servo telescopic rod 24 and the action of extending outward from the output end of the first servo motor 21, the tip end of the first pointed scraping block 43 is attached to the cross-section of the conduit. After the tip end of the first pointed scraping block 43 is attached to the cross-section of the conduit, the rotation action of the output end of the first servo motor 21 can be used again to make the tip end of the first pointed scraping block 43 rotate and scrape while attached to the cross-section of the conduit, keeping the cross-section intact.

[0029] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the second multi-stage adjustment module 4 includes a tray block 41. An extended wing rod 42 is fixedly connected to the outer edge of the tray block 41, and a first pointed scraping block 43 parallel to the side wall of the chassis cabinet 1 is fixedly installed outside the tray block 41 through the extended wing rod 42. A pointed block is fixedly installed on the side of the first pointed scraping block 43 away from the tray block 41, and a first reserved notch 46 is opened on the side of the first pointed scraping block 43 close to the tray block 41.

[0030] Among them, the configured tray block 41 is integrally installed on the output end of the electric servo telescopic rod 24 to expand and contract in cooperation with the telescopic of the electric servo telescopic rod 24. The extended wing rod 42 is integrally of a U-shaped structure and is used to fix the first pointed scraping block 43 outside the tray block 41. The first pointed scraping block 43 is integrally of a structure with a pointed block on one side and an open block with a first reserved notch 46 on the other side.

[0032] Among them, the configured third servo motor 44 has the same structure as the first servo motor 21 and the second servo motor 22, and is used to control the first gear plate 45 on the output end thereof to rotate, so that the second gear plate 47 meshing on the outside rotates synchronously. Once the second gear plate 47 rotates, the threaded rods 48 on the upper and lower surfaces can be rotated. Once the threaded rods 48 on the two surfaces rotate, the nut sleeve block 71 slidably mounted in the first reserved slot 46 can be moved up and down.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the cut surface scraping mechanism 7 includes a nut sleeve 71 meshingly mounted at the same position on the threaded rods 48 on the upper and lower sides of the second gear plate 47, and a platform partition 72 whose side surface is in contact with the pointed mouth surface of the first pointed mouth scraper 43 is fixedly mounted on the outer side of each nut sleeve 71 through a wing plate, and a cavity shell 73 is fixedly mounted on the surface of the platform partition 72 on the side facing the midpoint of the first pointed mouth scraper 43, and a plurality of lifting and inflation modules 711 are fixedly mounted at the middle position of the surface of the cavity shell 73.

[0034] The configured nut sleeve 71 is integrally fitted tightly into the first reserved notch 46 on the same side to cooperate with the threaded rods 48 on both surfaces to move up and down.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9As shown, the jacking and inflating module 711 includes a sealed cavity 7111. Inside the sealed cavity 7111, a reset spring sleeve 7112 is fixedly installed. And on each reset spring sleeve 7112, an outer jacking sleeve 7113 that can penetrate through the top of the sealed cavity 7111 is fixedly connected. And on the end face where the bottom of the outer jacking sleeve 7113 is connected to the reset spring sleeve 7112, a disc is configured to prevent the entire outer jacking sleeve 7113 from being jacked outwards. And at the center position of the bottom of each disc, a linkage outer extension rod 7114 that can penetrate through the bottom of the sealed cavity 7111 is fixedly connected.

[0036] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the section scraping mechanism 7 further includes an inflation chamber 710 opened at the middle position of the inner cavity of the cavity housing 73. The linkage outer extension rods 7114 all penetrate into the inflation chamber 710 from the top of the cavity housing 73 in a sealed manner. And at the penetrating end, a first piston sleeve plate 714 is fixedly installed. On the outer edge of the first piston sleeve plate 714, a sealing ring that fits against the inner wall of the inflation chamber 710 is fixedly installed. On the outside of the outer jacking sleeve 7113, a second pointed scraping block 712 is fixedly installed.

[0037] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, storage boxes 77 are fixedly installed on both sides of the cavity housing 73. At the middle position of the other side of the cavity housing 73 away from the second pointed scraping block 712, two inflation ducts 79 that extend outwards from the inside of the inflation chamber 710 are fixedly installed. And the extending ends of the inflation ducts 79 are all connected to the storage box 77 on the same side in a communicating manner. And on the inner side surface of each storage box 77, a second ventilation slot 716 for communicating the inflation duct 79 with the inside of the storage box 77 is opened. And a second piston sleeve plate 717 is slidably installed inside each storage box 77.

[0038] Among them, the configured storage box 77 is an overall liquid storage box structure with a cavity inside. On one side of its housing interior, a second ventilation slot 716 is opened. The second ventilation slot 716 penetrates from the side for connecting the inflation duct 79. The other side penetrates out from the top of the inner cavity of the storage box 77. By supplying air to the inside of the cavity, the second piston sleeve plate 717 inside is continuously pushed and extruded.

[0039] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 shown, the section scraping mechanism 7 further includes an inwardly inclined air guide frame 75 fixedly installed on both side edges of the cavity housing 73 on the same side as the second pointed nozzle scraping block 712. The overall orientation of the inwardly inclined air guide frame 75 is parallel to the inclined surface of the second pointed nozzle scraping block 712 on the same side. Servo fans 76 are fixedly installed on the outer side surfaces of the platform partition plates 72, and first ventilation slots 74 communicating with the inwardly inclined air guide frame 75 are opened on both sides of the surface of the platform partition plate 72 for the air ducts of the servo fans 76 to pass through.

[0040] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 shown, liquid conduction pipes 718 are fixedly installed on the other sides of the outer side surfaces of the storage boxes 77 opposite to the communication ports of the second ventilation slots 716, and the liquid conduction pipes 718 all extend into the inwardly inclined air guide frames 75 on the same side, and atomizing nozzles 715 are fixedly installed at the extending ends. Second reserved slots 78 for embedding the air inflation pipes 79 are opened at the middle positions of the surfaces of the platform partition plates 72, and one-way valve covers 713 are hingedly installed at the corner positions close to the inflation chambers 710 inside each air inflation pipe 79.

[0041] Among them, the configured one-way valve covers 713 are located at the corner positions close to the inflation chambers 710 inside each air inflation pipe 79. The reason for the corner of each configured air inflation pipe 79 is to be flush with the outer surface of the cavity housing 73 and be embedded in the second reserved slot 78. The one-way valve cover 713 arranged at the corner position is a disk seal cover structure hingedly fixed in the prior art. It can open towards the inflation side of the air inflation pipe 79, and during the reset process of the first piston sleeve plate 714, it will close the valve port under negative pressure to control the unidirectional output of gas. The atomizing nozzle 715 is a nozzle structure capable of atomizing in the prior art. Its input port end is composed of 4 mutually close-fitting sector-shaped partitions. As shown in the attached Figure 8 figure, it is in a closed state without the action of extrusion force, and will be pushed open under the action of extrusion force to play a role of real-time sealing; The overall working principle of the section scraping mechanism 7 is specifically as follows: First, under the above-mentioned operation, after the cut surface of the conduit is initially trimmed by the high-speed cutting module 3, the first pointed scraper 43 is controlled to be closely attached to the outer side of the cut surface of the conduit fixed by the part fastening crane 5 in cooperation with the multi-stage adjustment function of the second multi-stage adjustment module 4; Then, the tray block 41 is lifted to a suitable height by the electric servo telescopic rod 24, at which the second sharp-nosed scraper blocks 712 on the upper and lower sides of the first sharp-nosed scraper block 43 are respectively attached to the outer surface and the inner annular wall of the catheter, and in order to adapt to catheters of more sizes, the third servo motor 44 on the tray block 41 can also rotate to control the second gear plate 47 meshing on the outer side to adjust the spacing of the upper and lower cut surface scraping mechanisms 7 with the threaded rods 48 on both sides; Then, after the second pointed-mouth scrapers 712 on both sides are respectively attached to the outer surface and the inner circular wall of the conduit, the servo drive of the first servo motor 21 can control the second multi-stage adjustment module 4 to rotate as a whole to perform section processing around the circular arc of the conduit. In the process of processing, the second pointed-mouth scrapers 712 on both sides attached to the outer surface and the inner circular wall of the conduit can be further brought closer through the rotation of the output end of the third servo motor 44, so that the lifting and inflating modules 711 on the end faces of the second pointed-mouth scrapers 712 are squeezed. In the squeezed state, the outer push sleeve 7113 is squeezed into the sealed cavity 7111, so that one side of the linkage extension rod 7114 stored in the sealed cavity 7111 extends out, and once the linkage extension rod 7114 extends out, it pushes the first piston sleeve 714 in the gas filling chamber 710 inside the cavity shell 73 to pump air into the gas filling conduit 79, similar to the air pump in the prior art. After the gas is pumped into the gas filling conduits 79 on both sides, the one-way valve cover 713 is pushed outward, so that the gas enters the cavity of the storage box 77 through the second ventilation slot 716; As the third servo motor 44 controls the first gear plate 45 at its output end to rotate back and forth, the second pointed scraper block 712 reciprocates to draw the first piston sleeve plate 714 in the gas charging chamber 710, and continuously delivers gas to the inside of the storage box 77, so that the gas pressure inside the storage box 77 increases, so as to push the second piston sleeve plate 717 inside the storage box 77 to squeeze the liquid stored inside into the atomizing nozzle 715 in the inward-inclined air guide frame 75 on both sides through the liquid-passing conduit 718; At this time, by turning on the servo blower 76 outside the platform partition 72, it is also possible to blow the atomized reagent onto both side surfaces of the catheter with the wind blown by the servo blower 76. It only needs to store the metal multi-functional reagent in the storage boxes 77 on both sides, and the atomized reagent can directly act on the cut surface along with the scraping end. It is applicable to metal parts, especially parts with multi-step processing. Since the metal multi-functional reagent contains lubricants, abrasive particles and polishing components, it can complete deburring, grinding and polishing in one operation, further improving the effect of cut surface treatment. And before the second nozzle scraping block 712 is reciprocally extruded and the atomized reagent is ejected, the servo blower 76 can also blow air outwards through the inwardly inclined air guiding frame 75 to improve the ability of the second nozzle scraping block 712 to remove burrs during the conventional scraping process. At the same time, the continuous air flow can also remove the static electricity on the catheter cut surface caused by high-speed cutting, optimizing the cut surface treatment effect; Since the scraping force of the entire structure and the spraying of the auxiliary reagent are both controlled by the third servo motor 44, the interference problem during the operation of multiple driving mechanisms is reduced, and the fault tolerance rate of the linkage end is improved.
