Description

Technical Field

[0001] This invention relates to the field of casting processing equipment technology, specifically to a turning, milling, and drilling composite machining device for precision casting processing. Background Technology

[0002] As is well known, precision castings are widely used in high-end manufacturing fields such as aerospace, automotive parts, and medical devices due to their complex shapes, high dimensional accuracy, and excellent mechanical properties. The processing of these castings often requires multiple processes such as turning, milling, and drilling. Traditional single processing equipment requires multiple clamping of the workpiece, which is prone to positioning errors and cannot meet the stringent processing requirements of precision castings. Therefore, the combined turning, milling, and drilling processing equipment has emerged.

[0003] The milling-turning-turning (MTU-D) machining center integrates multiple machining functions such as turning, milling, and drilling. It can complete multiple machining operations in a single workpiece clamping, effectively reducing the number of clamping operations, lowering positioning errors, and significantly improving machining accuracy and production efficiency. It has become a core piece of equipment for precision casting machining. During precision casting machining, a large amount of metal shavings are generated. If these shavings are not collected and cleaned in a timely manner, they will not only scatter in the machining area, affecting machining accuracy and equipment operational stability, but may also pose a safety hazard to operators. Therefore, a shavings collection structure is an essential component of the milling-turning-turning (MTU-D) machining center.

[0004] Currently, the chip collection structure equipped in existing milling and turning machining centers for precision casting is designed to collect the chips generated during machining from the chip removal channel. However, in practical applications, this type of collection structure has significant shortcomings. The most prominent issue is that the chips generated during precision casting machining are mostly aluminum chips, cast iron chips, etc. These chips tend to form a loose, fluffy shape during cutting, with large gaps between adjacent chips and extremely low density. This causes the chip collection container to fill up quickly, requiring operators to frequently stop the machine for cleaning, affecting machining continuity and reducing production efficiency. At the same time, the fluffy chips occupy a large amount of storage space, increasing the space cost of the workshop and potentially causing chip overflow due to excessive accumulation, polluting the machining environment and increasing the difficulty of equipment maintenance. Summary of the Invention

[0005] To overcome the problem of large space occupied by loose waste chips during waste chip collection in existing mill-turn-drill composite machining devices for precision casting, this invention provides a mill-turn-drill composite machining device for precision casting that reduces the space occupied by loose waste chips and improves waste chip collection efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a turning-milling-drilling composite machining device for precision casting machining, comprising a machine body, which is a turning-milling-drilling composite device; a chip removal channel disposed on one side of the machine body; a collection box disposed on one side of the machine body; two sets of hydraulic cylinders disposed on one side of the collection box; a connecting plate disposed at the output end of the two sets of hydraulic cylinders; a pressing plate slidably disposed inside the collection box; a collection port opened on one side of the pressing plate, the collection port being aligned with the chip removal channel, thereby allowing waste chips to enter the collection box through the collection port; and the pressing plate and the connecting plate being fixedly disposed; and a shielding assembly, the shielding assembly including a fixed...

A push plate is slidably arranged inside the sliders, and the swing plates and push plates are slidably arranged.

[0016] Beneficial effects

[0017] This milling and turning combined machining device for precision castings incorporates a pressing plate. When the pressing plate is pushed, it compresses the loose waste chips inside the collection box, thus avoiding the problem of large space occupied by loose waste chips. Furthermore, by incorporating a baffle, when the baffle is pushed, it blocks the collection port. This prevents the waste chips from overflowing through the collection port while the pressing plate is compressing the waste chips, effectively preventing waste chips from splashing into the machining area and affecting machining accuracy, while also preventing waste chips from contaminating the internal components of the equipment.

[0032] See Figures 1 to 9A milling-turning composite machining device for precision casting machining includes a machine body 1, which is a milling-turning composite machine tool. A chip removal channel 4 and a collection box 5 are provided on one side of the machine body 1. A chip removal door 6 is provided on one side of the collection box 5. Two sets of support frames 7 are fixedly connected to one side of the collection box 5. A hydraulic cylinder 12 is fixedly installed on one side of the support frame 7. The output ends of the two sets of hydraulic cylinders 12 are fixedly connected to a connecting plate 9. Two sets of top rollers 11 are fixedly connected to one side of the connecting plate 9. An extrusion plate 8 is slidably connected inside the collection box 5, and the extrusion plate 8 is fixedly connected to the two sets of top rollers 11. A collection port 13 is opened on one side of the extrusion plate 8, and the collection port 13 is aligned with the chip removal channel 4. A shielding component 2 is provided inside the extrusion plate 8, and a drive component 3 is provided on one side of the extrusion plate 8.

[0033] After the hydraulic cylinder 12 is activated, the output end of the hydraulic cylinder 12 will push the connecting plate 9 to move longitudinally. The displacement of the connecting plate 9 will push the extrusion plate 8 to move longitudinally by pushing the top roller 11. The displacement of the extrusion plate 8 will extrude the loose waste in the collection box 5, thereby avoiding the problem of loose waste occupying a lot of space.

[0034] First, refer to Figures 3 to 8 In this embodiment, the shielding component 2 includes a fixed plate 201 and a baffle 203. The fixed plate 201 is fixedly connected to the inside of the extrusion plate 8. Two sets of support seats 216 are fixedly connected to one side of the fixed plate 201. A fixed column 215 is fixedly connected inside the support seat 216. A swing plate 224 is rotatably connected to the outside of the fixed column 215, and the swing plate 224 is inclined. Two sets of sliders 202 are slidably connected to the outside of the fixed plate 201. A push plate 214 is slidably connected inside the slider 202. A moving column 221 is fixedly connected inside the push plate 214. The side of the swing plate 224 away from the fixed column 215 is slidably connected to the outside of the moving column 221. Both sides of the push plate 202 are fixedly connected to a placement plate 219. A guide rod 218 is slidably connected inside the placement plate 219. Both sides of the push plate 214 are fixedly connected to a movable plate 217. The movable plate 217 is fixedly connected to one end of the guide rod 218. An operation plate 223 is fixedly connected to the outside of the guide rod 218. A movable frame 220 is slidably connected to the outside of the guide rod 218. A second spring 222 is fixedly connected between the movable frame 220 and the operation plate 223. A mounting base 213 is fixedly connected to the side of the push plate 214 away from the slider 202. A top block 212 is fixedly connected to one side of the mounting base 213. A push rod 211 is fixedly connected to one side of the top block 212.

[0035] The baffle 203 is slidably connected inside the extrusion plate 8. A fixing frame 210 is fixedly connected to one side of the baffle 203. A groove 209 is opened inside the fixing frame 210, and the push rod 211 is slidably connected inside the groove 209.

[0036] Specifically, in order to maintain the balance of the baffle 203, two sets of limiting rods 206 are fixedly connected inside the extrusion plate 8, and two sets of movable discs 207 are fixedly connected inside the baffle 203. The movable discs 207 are slidably connected to the outside of the limiting rods 206. Thus, on the one hand, the limiting rods 206 maintain the balance of the baffle 203 during movement, preventing the baffle 203 from becoming unbalanced and swaying during movement, and ensuring the normal displacement of the baffle 203. On the other hand, the limiting rods 206 restrict the direction of the baffle 203, preventing the device from failing due to misalignment of the baffle 203, and ensuring the normal use of the device.

[0037] Meanwhile, in order to enable the baffle 203 to move back quickly, a fixed plate 205 is fixedly connected to the outside of the limiting rod 206, and a first spring 204 is fixedly connected between the fixed plate 205 and the movable plate 207. Thus, when the baffle 203 is pushed, the movable plate 207 will squeeze the first spring 204, and when the baffle 203 is no longer pushed, the first spring 204 will bounce the baffle 203 back quickly by bouncing the movable plate 207 back.

[0038] Furthermore, in order to prevent the baffle 203 from excessively shifting back and disengaging from the limiting rod 206, a blocking plate 208 is fixedly connected to the outside of the limiting rod 206, and the blocking plate 208 is located on the side of the baffle 203 away from the fixed plate 205. Thus, the blocking plate 208 can block the baffle 203, avoiding the situation where the baffle 203 excessively shifts back and disengages from the limiting rod 206.

[0039] When the slider 202 is pushed, the slider 202 will push the push plate 214 to move. The displacement of the push plate 214 will push the moving column 221 to move. The displacement of the moving column 221 will push the swing plate 224. At this time, the swing plate 224 will swing around the fixed column 215 as the axis. The swing of the swing plate 224 will push one side of the moving column 221 to move towards the baffle 203. The displacement of the moving column 221 will push the push plate 214 to move towards the baffle 203. The displacement of the push plate 214 will push the push rod 211 to move by pushing the mounting base 213 and the top block 212. The displacement of the push rod 211 will push the baffle 203 to move by pushing the fixed frame 210. At this time, the baffle 203 will block the collection port 13. Thus, when the extrusion plate 8 extrudes waste chips, the waste chips will not overflow through the collection port 13, effectively preventing waste chips from splashing into the processing area and affecting the processing accuracy, while avoiding waste chips from contaminating the internal parts of the equipment.

[0040] Finally, see Figure 4 and Figure 9In this embodiment, the drive assembly 3 includes a rotary motor 301, which is a bidirectional motor whose output can rotate forward or backward. The rotary motor 301 is disposed on one side of the extrusion plate 8. A connecting rod 302 is keyed to the output of the rotary motor 301. A first threaded tube 305 is provided at the end of the connecting rod 302 away from the rotary motor 301. A rotating column 306 is provided at the end of the first threaded tube 305 away from the connecting rod 302, and a second threaded tube 307 is provided at the end of the rotating column 306 away from the first threaded tube 305. Parallel plates 304 are screwed onto the outer sides of both the first threaded tube 305 and the second threaded tube 307. A disc 303 is fixedly connected to the outer sides of both the first threaded tube 305 and the second threaded tube 307. The disc 303 can block the parallel plates 304 and parallel... Plate 304 and slider 202 are fixedly installed. A protective cover 10 is provided on one side of the extrusion plate 8. The protective cover 10 is located outside the rotary motor 301, the first threaded tube 305 and the second threaded tube 307. Thus, the protective cover 10 can protect the rotary motor 301, the first threaded tube 305 and the second threaded tube 307. After the rotary motor 301 is turned on, the output end of the rotary motor 301 will drive the connecting rod 302 to rotate. The rotation of the connecting rod 302 will drive the first threaded tube 305 to rotate. The rotation of the first threaded tube 305 will drive the second threaded tube 307 to rotate by driving the rotating column 306. The rotation of the first threaded tube 305 and the second threaded tube 307 will drive the two sets of parallel plates 304 to move linearly. The displacement of the parallel plates 304 will push the slider 202 to move.

[0041] This milling and turning combined machining device for precision castings incorporates a pressing plate 8. When the pressing plate 8 is pushed, it compresses the loose waste chips inside the collection box 5, thus avoiding the problem of large space occupied by loose waste chips. Furthermore, by incorporating a baffle 203, when the baffle 203 is pushed, it blocks the collection port 13. In this case, when the pressing plate 8 compresses the waste chips, the waste chips will not overflow through the collection port 13, effectively preventing waste chips from splashing into the machining area and affecting machining accuracy, while also preventing waste chips from contaminating the internal components of the equipment.

[0042] Working principle:

[0043] This milling-turning composite machining device for precision castings operates by activating the rotary motor 301, which drives the connecting rod 302 to rotate. The rotation of the connecting rod 302 causes the first threaded tube 305 to rotate, which in turn drives the second threaded tube 307 via the rotating column 306. The rotation of the first and second threaded tubes 305 causes linear displacement of the two sets of parallel plates 304. This displacement pushes the slider 202, which in turn pushes the push plate 214, which in turn pushes the moving column 221. The displacement of the moving column 221 then actuates the swing plate 224. At this point, the swing plate 224 will move relative to the fixed column 224. The oscillating plate 224 swings around the axis 15. The oscillation of the oscillating plate 224 will push one side of it to move the moving column 221 towards the baffle 203. The displacement of the moving column 221 will push the push plate 214 towards the baffle 203. The displacement of the push plate 214 will push the push rod 211 by pushing the mounting base 213 and the top block 212. The displacement of the push rod 211 will push the baffle 203 by pushing the fixed frame 210. At this time, the baffle 203 will block the collection port 13. Then, the hydraulic cylinder 12 will be opened so that its output end pushes the connecting plate 9 to move longitudinally. The displacement of the connecting plate 9 will push the extrusion plate 8 to move longitudinally by pushing the top roller 11. The displacement of the extrusion plate 8 will extrude the loose waste in the collection box 5, thereby avoiding the problem of loose waste occupying a lot of space.
