Description

Technical Field

[0001] This application relates to the field of die casting machine parts processing technology, and in particular to a composite machine tool for processing die casting machine cylinders. Background Technology

[0002] The addition and subtraction of materials in die-casting machine barrels aims to improve their service life. Traditional methods include carburizing, quenching, and nitriding. However, in recent years, laser cladding technology has replaced traditional processing methods. Laser cladding refers to the generation of a molten pool on the surface of a part by a laser, into which metal powder is automatically added automatically through a nozzle to form weld beads. This can form a coating or shape an entire part on an existing substrate, imparting special mechanical, physical, and chemical properties not present in the substrate itself, thereby improving the quality and performance of the parts and extending their service life. The method is simple, efficient, low-pollution, and has high utilization rates. Furthermore, the cladding status inside the barrel can be transmitted to a computer in real time via a visual sensor.

[0003] After laser cladding, the unevenness of the cladding layer necessitates further surface repair using a boring tool to increase surface smoothness and improve workpiece surface quality. This results in a secondary clamping issue, which is not only time-consuming and labor-intensive but also leads to coaxiality deviations between the two hot and cold processing operations, thus affecting accuracy. To address these problems, a composite machine tool for machining die-casting machine cylinders is proposed. Utility Model Content

[0029] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0031] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0032] One preferred embodiment of this application, such as Figures 1 to 11As shown, a composite machine tool for machining die-casting machine cylinders includes a machine tool 1, a cylinder component 2 (i.e., the die-casting machine cylinder to be machined), a moving mechanism 3, a machining device 4, and a support device 5. The cylinder component 2 is horizontally mounted on the three-jaw chuck 101 of the machine tool 1. The moving mechanism 3 is mounted on the machine tool 1. The machining device 4 is horizontally mounted on the moving mechanism 3 via a boring bar 6, i.e., the first end of the boring bar 6 is mounted on the moving mechanism 3, and the machining device 4 is mounted on the second end of the boring bar 6. The support device 5 is mounted on the machine tool 1 and cooperates with the cylinder component 2.

[0033] Understandably, the processing device 4 is first adjusted by the moving mechanism 3 so that it extends into the appropriate position inside the cylinder 2. Then, under the action of the moving mechanism 3, the processing device 4 performs laser cladding and boring operations on the inside of the cylinder 2. Laser cladding involves fusing metal powder onto the inner wall of the cylinder 2, forming a coating with special properties that improves the service life and performance of the cylinder 2. Boring is performed using a boring bar 402 to bore the clad inner wall of the cylinder 2, improving surface finish and workpiece surface quality. During processing, the support device 5 acts as a limiting support for the cylinder 2, ensuring it remains horizontal and preventing bending deformation, thereby improving processing accuracy and stability.

[0034] As a further description of the above embodiments: such as Figures 7 to 9 As shown, the support device 5 includes a pair of rollers 503, an adjustment component 1 501 and an adjustment component 2 502. The adjustment component 1 501 is mounted on the machine tool 1, the adjustment component 2 502 is mounted on the adjustment component 1 501, and the rollers 503 are mounted on the adjustment component 2 502.

[0035] Understandably, during the processing of the cylinder 2, the rollers 503 support and limit its movement. The rollers 503 are designed to reduce frictional resistance during support, allowing the cylinder 2 to rotate smoothly. The combined use of adjustment components 1 501 and 2 502 enables precise adjustment of the height and spacing of the rollers 503 to accommodate the processing needs of cylinders 2 with different dimensions. Specifically, adjustment component 1 501 drives the rollers 503 to move vertically, ensuring they fit snugly against the outer wall of the cylinder 2 and provide stable support. Adjustment component 2 502 adjusts the distance between the two rollers 503 to accommodate cylinders 2 with different diameters, ensuring the applicability and flexibility of the support device 5.

[0036] This application does not specifically limit the structure of adjustment component 501 and adjustment component 502. The following provides a specific embodiment for reference:

[0037] like Figure 8 and Figure 9 As shown, the first adjustment assembly 501 includes a housing 5011, a worm 5013, a worm wheel 5012, a gear 5015, and a rack 5014. The worm 5013 is horizontally rotatably mounted inside the housing 5011. The worm wheel 5012 is rotatably mounted inside the housing 5011 via a rotating shaft and meshes with the worm 5013. The gear 5015 is sleeved and mounted on the rotating shaft. The rack 5014 is vertically slidably mounted on the housing 5011 and its top end is connected to the second adjustment assembly 502.

[0038] Understandably, during height adjustment, the worm 5013 is rotated via a crank handle. The worm 5013 acts on the worm wheel 5012, which in turn drives the shaft to rotate. This causes the gear 5015 to rotate and act on the rack 5014, which in turn drives the adjusting assembly 502 and the roller 503 to move up and down. It should be noted that the worm wheel 5012 and worm 5013 have a self-locking mechanism; therefore, after adjustment, once the worm 5013 stops rotating, the height of the roller 503 remains stable, further improving machining stability and precision. Furthermore, the high transmission ratio of the worm wheel 5012 and worm 5013 provides speed reduction and torque increase, allowing the operator to achieve precise height adjustment of the roller 503 with relatively little force, improving operational convenience. Of course, the adjusting assembly 501 can also be automatically adjusted, for example, by a hydraulic cylinder or a pneumatic cylinder.

[0039] like Figure 10 and Figure 11 As shown, the adjustment assembly 502 includes a support plate 5021, a bidirectional lead screw 5022, a pair of connecting rods 5023, a pair of traction blocks 5024, and a guide rail 5025. The support plate 5021 is fixedly installed on the top of the rack 5014. The connecting rods 5023 are rotatably installed on both sides of the top of the support plate 5021 and are symmetrically distributed. The rollers 503 are installed on the top of the connecting rods 5023. The traction blocks 5024 are rotatably installed in the middle of the connecting rods 5023 and are threadedly engaged with the bidirectional lead screw 5022. The guide rail 5025 is vertically installed in the middle of the support plate 5021 and engages with the bidirectional lead screw 5022.

[0040] Specifically, the bidirectional lead screw 5022 is a left-hand and right-hand lead screw. The left-hand thread of the lead screw cooperates with a traction block 5024, and the right-hand thread of the lead screw cooperates with another traction block 5024. The guide rail 5025 limits the vertical movement of the bidirectional lead screw 5022, allowing it to move vertically along the guide rail 5025 while rotating. In other words, when adjusting the spacing, rotating the bidirectional lead screw 5022 with the crank handle causes it to act on the two traction blocks 5024, causing them to move relative to or away from each other. The traction blocks 5024 then drive the two connecting rods 5023 to rotate relative to or away from each other, thus adjusting the spacing by allowing the two rollers 503 to rotate closer together or further apart.

[0041] For example, such as Figure 11 As shown in the diagram above, when the diameter of the material cylinder 2 is large, the double-acting screw 5022 can be rotated clockwise, causing the two traction blocks 5024 to move away from each other. This means the two connecting rods 5023 drive the rollers 503 to rotate in opposite directions, increasing the distance between them. Adjusting to a suitable large distance is sufficient. Conversely, when the diameter of the material cylinder 2 is small, as... Figure 11 As shown in the figure below, rotating the bidirectional lead screw 5022 counterclockwise will reduce the distance between the two rollers 503. Adjust it to a suitable small distance.

[0042] Of course, the adjustment component 502 mentioned above can also adopt the following structure (not shown): the adjustment component 502 includes a support plate 5021, a bidirectional lead screw 5022, a pair of connecting rods 5023 and a pair of traction blocks 5024, wherein the support plate 5021 is fixedly installed on the top of the rack 5014, the traction blocks 5024 are symmetrically slidably installed on the top of the support plate 5021, the bidirectional lead screw 5022 is horizontally rotatably installed on the top of the support plate 5021 and threadedly engaged with the traction blocks 5024, the connecting rod 5023 is fixedly connected to the top of the traction blocks 5024 through its bottom end, and the roller 503 is installed on the top of the connecting rod 5023; that is, this is equivalent to a "lead screw and slider structure", that is, the two rollers 503 are directly driven to move relative to each other or in opposite directions by the rotation of the bidirectional lead screw 5022.

[0043] It should be noted that when adjusting component 2 502 adopts form two (i.e., the roller 503 uses a movable adjustment method), in order to ensure that the roller 503 has sufficient adjustment distance, the two traction blocks 5024 need to have sufficient sliding space, which increases the length of the support plate 5021. When adjusting component 2 502 adopts form one, the roller 503 adjusts its position under the rotation of the connecting rod 5023. In other words, the longer the connecting rod 5023, the larger its adjustment range. Designers can reasonably set the actual length of the connecting rod 5023 according to the actual situation. It is understandable that within the same adjustment range, form one requires a smaller length of support plate 5021, resulting in better structural compactness, further reducing the space occupied by the entire device and improving space utilization. Moreover, in actual support, the force exerted by the cylinder 2 on the connecting rod 5023 is not vertically downward, but inclined to the connecting rod 5023. When the first form is adopted, the double-acting screw 5022 can also play a limiting support role for the two connecting rods 5023, thereby increasing the stability of the connecting rod 5023 support.

[0044] In one embodiment of this application, such as Figure 2 and Figure 3 As shown, the moving mechanism 3 includes a first moving component 301, a second moving component 302, and a third moving component 303. The first moving component 301 is mounted on the machine tool 1, the second moving component 302 is mounted on the first moving component 301, the third moving component 303 is mounted on the second moving component 302, and the machining device 4 is mounted on the third moving component 303 via a boring bar 6.

[0045] It is understandable that during the movement adjustment, the first moving component 301 can drive the second moving component 302, the third moving component 303 and the processing device 4 to move synchronously in the first direction; the second moving component 302 can drive the third moving component 303 and the processing device 4 to move synchronously in the second direction; the third moving component 303 is suitable for driving the processing device 4 to move in the third direction; wherein the three directions are different.

[0046] Specifically, such as Figure 1 As shown, we define the first direction as the x-direction (i.e., the left-right direction of machine tool 1), the second direction as the y-direction (i.e., the front-back direction of machine tool 1), and the third direction as the z-direction (i.e., the up-down direction of machine tool 1), thereby achieving six degrees of freedom adjustment. This enables the machining device 4 to perform all-around machining, greatly improving the flexibility and applicability of machining.

[0047] It should be understood that the specific structure and working principle of the three moving components are well known to those skilled in the art, and therefore will not be described in detail here. Common moving components include slide rails and drive sources. Taking moving component 301 as an example: the slide rail is fixedly installed on the machine tool 1, and a slider is slidably installed inside the slide rail. Moving component 302 is installed on this slider, and the slider is connected to the drive source. Thus, under the drive of the drive source, the slider can move along the slide rail (i.e., move in the x direction). Common drive sources include motors, cylinders, and hydraulic cylinders, which can then form a motor screw slider device or a pneumatic slide rail device, etc.

[0048] In one embodiment of this application, such as Figure 4 As shown, the processing device 4 includes a laser cladding head 401, a boring bar 402, and a support assembly 403. The laser cladding head 401 is installed in the boss 12 (i.e., the groove opened at the second end of the boring bar 6) at the second end of the boring bar 6. The boring bar 402 is installed at the top of the boring bar 6 and close to the boss 12. The support assembly 403 is installed at the end of the boring bar 6 and cooperates with the bottom of the inner end of the material cylinder 2.

[0049] Understandably, during processing, the laser cladding head 401 performs laser cladding on the barrel 2, and the boring bar 402 performs boring. During the boring process, the barrel 2 exerts a reaction force on the boring bar 402. Since the barrel remanufacturing involves deep hole machining, to prevent deformation of the boring bar 6 during operation, such as... Figure 5 As shown, at this time, the support component 403 will abut against the bottom of the inner part of the barrel 2, thereby providing support for the boring bar 6, increasing the rigidity of the boring bar 6 during the machining process, and improving the machining accuracy and stability.

[0050] Specifically, such as Figure 4 As shown, the support assembly 403 includes a telescopic member 4031 and a pulley 4032. The telescopic member 4031 is mounted on the end of the boring bar 6, and the pulley 4032 is mounted on the piston end of the telescopic member 4031. During machining, the telescopic member 4031 can extend to allow the pulley 4032 to move until it abuts against the inner bottom end of the barrel 2. The pulley 4032 reduces friction on the inner wall of the barrel 2, making the support more stable. The telescopic member 4031 can be a cylinder or a hydraulic cylinder, etc., and a hydraulic cylinder is preferred here because it offers better stability and motion control precision.

[0051] The specific installation method for the boring bar 402 is as follows: (See...) Figure 4As shown, a threaded hole 1 can be provided on the top side of the second end of the boring bar 6, and the boring tool 402 is installed in the threaded hole 1 by thread; a threaded hole 2 communicating with the threaded hole 1 can be provided on the side of the boring bar 6, and a bolt can be provided in the threaded hole 2; a slotted groove can be provided at the bottom end of the boring tool 402, and an operating hole communicating with the threaded hole 1 is provided on the bottom side of the second end of the boring bar 6.

[0052] Understandably, the boring bar 402 can be installed on the boring bar 6 through the threaded hole, and then a flathead screwdriver can be inserted through the operating hole to engage with the boring bar 402, allowing for minor adjustments to the boring bar 402. Finally, the boring bar 402 is tightened with bolts to achieve limiting and fixing (locking) of the boring bar 402, preventing it from loosening during operation.

[0053] It should be noted that the aforementioned installation method of the boring bar 402 not only facilitates its installation and disassembly but also makes it easier to replace and maintain later, greatly improving its ease of use. Furthermore, since the boring bar 402 is threaded onto the boring bar 6 and secured with bolts, its stability during machining is ensured, preventing it from shaking or falling off, thereby further improving machining accuracy and stability.

[0054] Based on the above embodiments, in this embodiment, as follows: Figure 4 As shown, the support assembly 403 can be mounted on the second end of the boring bar 6 via the drive device 8. It is understood that when the laser cladding head 401 is focusing, the drive device 8 can drive the support assembly 403 to rotate and move away from the focusing area, avoiding interference with the focusing of the laser cladding head 401 and ensuring focusing accuracy. After focusing is complete, the drive device 8 can then drive the support assembly 403 to rotate and reset. The specific structure and working principle of the drive device 8 can be designed according to actual needs; for example, it can be driven by a motor, rotary cylinder, or rotary hydraulic cylinder.

[0055] like Figure 4 As shown, the boring bar 6 has an internal hole 11 that communicates with the boss 12. The internal hole 11 can be used to arrange components that are connected to the laser cladding head 401, such as cooling pipes, powder feeding pipes, protective gas pipes and optical fibers required for laser cladding.

[0056] Furthermore, such as Figure 4As shown, a pressure detection module 9 (e.g., a force sensor) can be installed between the boring bar 6 and the drive device 8. The force sensor can detect the force on the telescopic component 4031 (e.g., a hydraulic rod). The force sensor transmits the data during operation to an external computer in real time in the form of an electrical signal. By observing the fluctuations in the electrical signal, it can be determined whether the material addition / subtraction operating rod deforms during operation or the uniformity of the laser cladding layer. Specifically: if the fluctuation value suddenly increases, it indicates that the cladding layer at that location is too thick; if the increase persists for a long time, it indicates that the operating rod may have deformed due to stress. If the fluctuation value suddenly decreases, it indicates that the cladding layer thickness is too thin.

[0057] Of course, such as Figure 4 As shown, a camera 10 is also installed at the end of the boring bar 6 (i.e., the second end), which can transmit the observed state of the cladding layer and the goodness of the molten pool to an external computer. It can also observe the focusing state of the laser during cladding. The optical image of the scene generated by the lens is projected onto the surface of the image sensor, then converted into an electrical signal. After A / D (analog-to-digital) conversion, it becomes a digital image signal, which is then processed by a digital signal processing chip (DSP). Subsequently, it is transmitted to a computer via a USB interface for further processing, and finally, the image can be viewed on a monitor.

[0058] The specific working steps of this utility model are as follows:

[0059] S100: First, the barrel 2 can be fixedly installed on the three-jaw chuck 101 of the machine tool 1 using a suitable clamp 7.

[0060] S200: Since the barrel 2 is a deep-hole machined part, to prevent deformation of the barrel 2 or the fixture 7, the barrel 2 can be supported and limited. Specifically, such as... Figure 10 and Figure 11 As shown, by rotating the double-acting screw 5022 with the crank handle, the two rollers 503 are placed at a suitable angle. Then, by rotating the worm gear 5013 with the crank handle, the two rollers 503 are moved upward until they abut against the material cylinder 2. This allows the material cylinder 2 to be limited and supported and to be in a horizontal state.

[0061] S300: Before the moving mechanism 3 moves the processing device 4 to the barrel 2, the telescopic member 4031 is rotated to the other side of the boring bar 6 by the drive device 8 to facilitate the calibration process of the processing device 4. The telescopic member 4031 is preferably a hydraulic rod, and the drive device 8 is preferably a rotary cylinder.

[0062] Specifically, firstly, the x-axis adjustment is performed using moving component 301, moving the processing device 4 to the port position of the barrel 2. Then, the y-axis adjustment is performed using moving component 302, ensuring that the laser cladding head 401 and the lowest point inside the barrel 2 are aligned. Finally, the z-axis adjustment is performed using moving component 303, thus achieving the focusing and calibration process of the laser cladding head 401. Similarly, when calibrating the boring bar 402, the above steps are repeated to achieve tool setting for the boring process. Of course, if height adjustment is needed during the tool setting process of the boring bar 402, it can be fine-tuned using a screwdriver in conjunction with the bottom of the boring bar 402, making the tool setting process more convenient and faster. Finally, with the cooperation of the moving mechanism 3, the processing device 4 can perform a combined laser cladding and boring process on the barrel 2.

[0063] It should be noted that in the actual machining process, because a hydraulic rod is provided on the machining device 4 at the end of the boring bar 6, the inner groove dimension (D1) of the barrel 2 is limited, that is, it cannot be too small, and is generally required to be between 220mm and 500mm. At the same time, in order to avoid the feed port of the barrel 2, the dimension (D2) of the hydraulic rod is also limited, and it must not exceed 300mm.

[0064] In summary, compared with traditional processing techniques for the barrel component 2, this application has the following advantages:

[0065] I. Improved Processing Efficiency: Composite machining equipment can simultaneously complete multiple processing steps, reducing workpiece fixture changes and process transition time, thereby improving overall processing efficiency. II. Space Saving: Integrating multiple processing functions into one device effectively saves production space and reduces the equipment's footprint. III. Improved Processing Accuracy: Composite machining reduces workpiece transfer between different machine tools, minimizing processing errors caused by inaccurate fixture or workpiece positioning, thus improving processing accuracy. IV. Reduced Production Costs: By reducing equipment investment, processing time, and increasing raw material utilization, composite machining equipment can effectively reduce production costs. V. Reduced Manual Operation: Composite machining equipment features a high degree of automation, reducing reliance on manual operation and thus improving safety and consistency.
