Description

Technical Field

[0001] The invention relates to the technical field of modular machine tools, in particular to a multifunctional modular machine tool for casting holes. Background Art

[0002] Modular machine tools occupy an important position in modern manufacturing. By combining multiple processing units, they can achieve efficient and diversified processing of various parts. In the field of casting processing, modular machine tools are often used for conventional processing operations such as milling, drilling, and boring of castings. With multi-axis linkage and modular design, they can improve processing accuracy and production efficiency.

[0003] However, in the specific application scenario of casting hole repair, the existing modular machine tool technology (such as a multifunctional modular machine tool for casting holes disclosed in the Chinese patent with publication number CN117415615A) has obvious shortcomings. During daily use or storage, impurities and oxide layers are easily generated on the surface of the casting holes. When performing casting hole repair operations, conventional modular machine tools can usually only complete simple repair operations such as welding, inlaying or bonding, but ignore the pretreatment of impurities and oxide layers on the surface of the casting holes. For example, although some modular machine tools are equipped with welding units that can perform welding repairs on damaged casting holes, due to the presence of impurities and oxide layers, the contact between the welding material and the metal surface is blocked, resulting in weak bonding and the repaired part is easy to fall off during subsequent use.

[0004] In addition, when the damage of the casting hole is small, such as the presence of fine cracks or damage, it is difficult for the combined machine tool to accurately identify these damaged locations due to the coverage of impurities and oxide layers, resulting in the omission of key parts in the repair work, which seriously affects the repair effect and the subsequent performance of the casting. Therefore, the development of a combined machine tool that can integrate multiple functions such as impurity cleaning, precise detection, and efficient repair to meet the special needs of casting hole repair has become an urgent problem to be solved in this field.

[0015] Compared with the known prior art, the technical solution provided by the present invention does not have the following beneficial effects: 1. Through the telescopic device, driving component, arc-shaped spray plate, material guide component and resonance component in the impurity removal and marking mechanism, the impurities and oxide layer on the surface of the casting hole are further cleaned, thereby exposing the metal layer of the casting hole. Among them, the telescopic device is used to drive the driving component, the arc-shaped spray plate and the resonance component to descend into the casting hole. When the driving component, the arc-shaped spray plate and the resonance component enter the casting hole, the motor will drive the driving component to rotate, so that the material guide component and the arc-shaped spray plate connected to the driving component will rotate synchronously. The material guide component will receive the non-ferromagnetic welding material powder transmitted by the material storage component while the motor rotates. Since the material guide component and the arc-shaped spray plate are in rotation at this time The powder transferred to the material guide component will be ejected from the arc-shaped spray plate under the dual action of centrifugal force and the power of the material storage component during transmission, so that the powder collides with the inner wall of the casting hole at a certain speed, thereby removing impurities and oxide layers on the surface of the casting hole. At the same time, the powder will be stuck in the damaged part of the casting hole due to its certain speed, thereby marking the damaged part of the casting hole, comprehensively removing stubborn impurities and oxide layers, and creating an ideal metal attachment surface for subsequent repair. The ejected powder is stuck in the damaged part, automatically completing the marking of the damaged position, which not only saves the extra marking step, but also allows the repair personnel to lock the key repair points at a glance, thereby improving the accuracy and efficiency of the repair.

[0016] 2. By fixing the welding robot arm, detector, lifting assembly, replacement parts and magnetic conductive assembly in the welding mechanism, the damage marked by the impurity removal marking mechanism can be repaired by welding. The welding robot arm is used to repair the damage by welding, and the detector detects the powder aggregation position and the powder area at the aggregation in the casting hole, so as to adjust the welding power accordingly. At the same time, the lifting assembly drives the replacement parts to start first, so as to achieve rough treatment of impurities and oxide layers in the casting hole, and the magnetic conductive assembly promotes the separation of impurities, oxide layers and the inner wall of the casting hole through irregular positive and negative magnetic poles. The lifting assembly drives the replacement parts to work first, and roughly treats the impurities and oxide layers, laying a solid foundation for subsequent fine repairs and greatly improving the overall repair efficiency. The magnetic conductive assembly uses irregular positive and negative magnetic poles to promote the separation of impurities and oxide layers from the inner wall of the casting hole, further optimizing the pretreatment effect before repair.

[0017] 3. Through the storage box, electrostatic rod, first suction pump, second suction pump and two-position three-way solenoid valve in the storage assembly, the adsorption of impurities and oxide layer impurities, as well as the separation of impurities, oxide layer impurities and powder are achieved. The first suction pump and the second suction pump are two suction pumps with opposite pumping directions, and the discharge and re-inhalation of the powder stored in the storage box are achieved through the conversion of the two-position three-way solenoid valve, so that the impurity removal marking mechanism can make the powder re-sucked from the casting hole into the storage box after completing the work, which can not only discharge the used powder in the storage box in time, but also quickly re-suck the powder in the casting hole into the storage box after the impurity removal marking mechanism is completed, so as to achieve powder recycling.

The fixed component 26 clamps the casting 100, but the side of the casting 100 facing the workbench 11 is in contact with the workbench 11.

Then, the controller controls the telescopic clamp 262 to extend and push the V-shaped clamp block 264 through the positioning seat 263 to fix and clamp the casting 100. After the V-shaped clamp block 264 completes the fixation of the casting 100, the controller receives the clamping signal and controls the driver 241 at the bottom of the base 1 to start, driving the hydraulic lifting rod 242 to rotate, and the hydraulic lifting rod 242 itself will also rise, and the drill connected to the telescopic end of the hydraulic lifting rod 242 starts to drill the casting 100.

[0039] 2. For a casting 100 having a casting hole, but the casting hole is damaged, perform the following operations: Step 1: First, place the casting 100 on the workbench 11, and then use the first working mode, except that the replacement part 25 at the module end of the hydraulic lifting rod 242 is a grinder, and at this time, the V-shaped clamping block 264 fixes and clamps the casting 100, and also seals the lower side of the casting hole of the casting 100 to prevent powder leakage in the subsequent impurity removal and marking process, and ensure that the powder can be gathered in the casting hole, which provides convenience for subsequent powder recovery; After the V-shaped clamping block 264 completes the fixing of the casting 100, the controller receives the clamping signal and controls the driver 241 at the bottom of the base 1 to start, driving the hydraulic lifting rod 242 on the upper end surface to rise and rotate, and the replacement part 25 fixedly connected to the telescopic end of the hydraulic lifting rod 242 also moves, thereby achieving preliminary grinding of the casting hole of the casting 100, removing some impurities and oxide layers in the hole, making the damaged position of the casting hole more obvious, so that the powder in the subsequent impurity removal marking mechanism can be accurately stuck at the damaged position; Note: The specific working time of the lifting component 24 and the replacement part 25 can be customized by the staff in the controller according to the actual situation.

[0040] When the fixing assembly 26 completes the fixing of the casting 100, the controller also synchronously controls the start-up of the magnetic conductive assembly 27. After the electromagnet is energized in the magnetic shield box, irregular positive and negative magnetic poles are generated in the magnetic conductive assembly 27 (the reason is that the magnetic pole characteristics of the electromagnet are determined by the current passing through. When the magnitude and direction of the current passing through the electromagnet change irregularly over time, the generated magnetic field will also change accordingly. The controller provides the electromagnet with an irregular pulse current through the current generator. This pulse current outputs a current with a complex waveform and no regularity, so that the current has different magnitudes at different times and the direction changes suddenly, so that the direction and strength of the magnetic field generated around the electromagnet are constantly irregular. Changes, thereby generating irregular positive and negative magnetic poles), the magnetic shield box can prevent the magnetic field from spreading outward irregularly, ensuring that the magnetic field can be effectively conducted along a specific path, one end of the magnetic rod 272 passes through the magnetic shield box and contacts the electromagnet, leading out the magnetic field generated by the electromagnet, and the positioning clamp 273 on the positioning seat 263, on the one hand, fixes the other end of the magnetic rod 272, and on the other hand, clamps the telescopic magnetic rod 274, the magnetic rod 272 is fixedly connected to the telescopic magnetic rod 274, so that the magnetic field can be smoothly transmitted to the telescopic magnetic rod 274, the telescopic magnetic rod 274 can be extended and retracted with the action of the V-shaped clamping block 264, ensuring that the magnetic field can stably act on the casting 100 (the casting 100 of this scheme has ferromagnetism); The magnetic ball 275 contacts the casting 100 to transfer the magnetic field to the casting 100. Under the action of the magnetic field, the impurities and oxide layer on the inner wall of the casting hole are affected by the irregular magnetic field force, and the bonding force with the inner wall of the casting hole is weakened, thereby promoting the separation of the impurities and oxide layer from the inner wall of the casting hole, providing a cleaner surface for subsequent welding repair and other work. At the same time, the magnetic force generated by the magnetic field also helps the auxiliary fixing component 26 to clamp the casting 100, reducing the risk of displacement of the casting during the repair process and ensuring the accuracy of the repair work; Note: The magnetic conductive component 27 will not stop working when the lifting component 24 and the replacement component 25 stop.

[0041] Step 2: After the preliminary cleaning of the casting hole of the casting 100 is completed, the telescopic device 31 at the bottom of the support frame 12 is extended, and its telescopic end drives the hollow connecting shaft 33, the motor 32, the driving assembly 34, the material guide assembly 35, the arc spray plate 36 and the resonance assembly 37 to descend together into the casting hole of the casting 100. Then, the controller controls the motor 32 to start, and the motor 32 drives the hollow shaft 341 to rotate by engaging the ring gear 342 through the driving gear, and the hollow shaft 341 drives the guide through the elastic shaft 343. The material assembly 35 and the arc-shaped spray plate 36 rotate synchronously, and at this time, the non-ferromagnetic powder stored in the material storage box 41 (the non-ferromagnetic powder can be: aluminum oxide, zirconium oxide, etc., so as to avoid the magnetic field of the magnetic conductive assembly 27 from affecting the subsequent powder marking. How to transfer the non-ferromagnetic powder stored in the material storage box 41 will be described later, and the subsequent non-ferromagnetic powder is referred to as powder) enters the guide pipe 352 through the diverter 411 and the discharge pipe 412, and then reaches the arc-shaped spray plate 36 through the branch pipe 353 and the distribution pipe 361; Since the arc-shaped spray plate 36 is in a high-speed rotating state, the powder is ejected at high speed from the spray hole of the arc-shaped spray plate 36 under the dual effects of centrifugal force and transmission power, and hits the inner wall of the casting hole. This not only removes impurities and oxide layers on the surface of the casting hole, but also some powder with a certain speed will be stuck in the damaged part of the casting hole, thereby marking the damaged position. While the powder is ejected at high speed from the spray hole of the arc-shaped spray plate 36, it will collide with the resonance component 37 inside the arc-shaped spray plate 36, so that the powder collides with the resonance fan plate 3722, and the resonance fan plate 3722 drives the torsion shaft 3721 to rotate, thereby generating vibration waves, thereby breaking up large powders that agglomerated during transmission or storage, preventing large powders from being ejected from the spray hole of the arc-shaped spray plate 36, and preventing large powders from clogging the spray hole or getting stuck in the damaged part of the casting hole, thereby preventing misjudgment of the detector.

[0042] The welding robot arm 21 performs welding repair on the damaged position of the casting hole marked by the impurity removal marking mechanism (the welding method provided by the welding robot arm 21 is arc welding), and the powder stuck in the damaged position is welding material powder, so when the welding robot arm 21 is welding, the welding material powder can act as welding raw material to assist the welding robot arm 21 in welding, thereby consuming the welding powder; The detector 23 on the fixed disk 22 (the detector 23 can be an acoustic wave detector or an optical detector) detects the powder aggregation position and the powder aggregation area in the casting hole in real time, and controls the power of the welding robot arm 21 when welding the corresponding position according to the detection result (the powder aggregation amount is proportional to the welding heating power so that the welding can be completed per unit time), ensuring the welding quality (the fixed component 26 is always in working state during this process), which can promote the separation of impurities, oxide layer and the inner wall of the casting hole, further optimize the pretreatment effect before welding, and improve the firmness of welding.

[0043] Step 3: The detector 23 detects that the powder used for marking has been consumed, indicating that the impurity removal and marking work is completed. Then the controller controls the two-position three-way solenoid valve 49 to be energized continuously for a set time to move the internal valve core and switch the two-position three-way solenoid valve to be connected with the first suction pipe 471. After the two-position three-way solenoid valve 49 is energized for 1 second, the first suction pump 47 is controlled to start. The first suction pump 47 sucks the powder in the casting hole into the storage box 41 through the first suction pipe 471, the two-position three-way solenoid valve 49, and the feed pipe 491 through the guide pipe 352. The powder first passes through the porous suction pipe 44 and then enters the storage box 41 through the second dividing block 413. The two groups of electrostatic rods 42 staggeredly distributed in the storage box 41 can adsorb impurities and oxides in the powder to achieve powder cleaning.

[0044] When the powder needs to be discharged for reuse by the impurity removal marking mechanism 3, the two-position three-way solenoid valve 49 is manually controlled by the controller to switch the internal valve core of the two-position three-way solenoid valve 49 again, so that the two-position three-way solenoid valve 49 and the second suction pipe 481 are started at the second suction pump 48, and the second suction pump 48 discharges the powder in the storage box 41 through the second discharge pipe 482, the diverter 411, and the discharge pipe 412 through the second suction pipe 481 and the two-position three-way solenoid valve 49. In addition, the connecting groove 431 and the partition plate 432 on the partition 43 work together with the heating block 45 to heat the recovered powder, which can not only remove moisture from the powder, but also thermally degrade impurities and oxides that are not completely adsorbed by the electrostatic rod 42, thereby ensuring the quality of the powder and realizing the recycling of the powder.
