Description

Technical Field

[0001] This invention relates to the technical field of planetary roller screw machining devices, specifically a planetary roller screw cutting and drilling machining device with automatic feeding function. Background Technology

[0002] Planetary roller screws are high-precision, high-load linear transmission devices consisting of a screw, a nut, and multiple planetary rollers. Their working principle is similar to that of planetary gears, with the rollers rolling between the screw and the nut to achieve efficient force transmission. Compared to traditional ball screws, planetary roller screws have higher load-bearing capacity, longer lifespan, and better rigidity, making them suitable for heavy-duty, high-speed, and high-precision applications, such as aerospace, industrial robots, and high-end machine tools.

[0003] As a transmission component, the lead screw generates heat during use, requiring through holes to circulate coolant and improve its quality. Therefore, drilling is performed on the lead screw on a machine tool.

[0004] Currently, most machine tool operations involve manual loading and unloading, followed by unloading and reloading after processing. This results in low production efficiency and poses a risk of worker injury due to machine tool malfunction. Manual loading and unloading does not meet current demands for production efficiency or ensure worker safety during installation. Summary of the Invention

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Example: Figures 1-6As shown, this invention provides a planetary roller screw processing device with automatic feeding function. The device includes a machine tool 1 and a support plate 2. The machine tool 1 has positioning holes 3 and a guide rail 4. A receiving seat 5 is slidably mounted on the guide rail 4, and a fixed half-ring 6 is hinged to the receiving seat 5. The machine tool 1 and the support plate 2 are connected via a sliding plate 7. The sliding plate 7 is slidably connected to both the support plate 2 and the machine tool 1. A drilling cutter 8 is mounted on the sliding plate 7, and a first partition 9 is mounted on the side of the drilling cutter 8 closest to the machine tool 1. The wall of the machine tool 1 away from the support plate 2 is connected by a clamping electric telescopic rod 10. A feeding frame 11 is installed on the machine tool 1. An adjusting electric telescopic rod 12 is installed on the side wall of the feeding frame 11. A movable plate 13 is installed at the end of the adjusting electric telescopic rod 12. A blocking electric telescopic rod 14 and a discharging electric telescopic rod 16 are installed at the lower part of the feeding frame 11. The discharging electric telescopic rod 16 is located below the blocking electric telescopic rod 14. A blocking rod 15 is installed at the end of the blocking electric telescopic rod 14. A discharging baffle 17 is installed at the end of the discharging electric telescopic rod 16. A discharging inclined plate 18 is installed on the machine tool 1.

[0044] In the initial state, the electric telescopic rod 14 for stopping is in the retracted state, while the electric telescopic rod 16 for discharging and the electric telescopic rod 10 for pressing are in the extended state. When it is necessary to drill internal holes in the screw, the screw is placed in the feeding frame 11. The electric telescopic rod 16 for discharging is controlled to retract at regular intervals, and the electric telescopic rod 14 for stopping is controlled to extend at regular intervals, so that the bottom screw to be processed falls downwards and falls along the feeding ramp 18 onto the receiving seat 5 and the positioning hole 3. After the electric telescopic rods 16 for discharging and the electric telescopic rod 14 for stopping return to their initial state, the electric telescopic rod 10 for pressing retracts, so that the first partition 9 pushes the product to move towards the positioning hole 3. After positioning, the drilling cutter 8 drills holes in the product by turning it inwards. Through the alternating extension of the feeding baffle 17 of the stopping rod 15, the products in the feeding frame 11 are ensured to fall one by one to the processing position, realizing automatic feeding, which can improve production efficiency and production safety.

[0045] The electric telescopic rod 12 can be directly controlled by the worker, making it convenient to put raw materials of different lengths into the feeding frame 11.

[0046] Two spring sleeves 19 are symmetrically installed on both sides of the receiving seat 5. One spring sleeve 19 is connected to the machine tool 1, and the other spring sleeve 19 is connected to the first partition 9.

[0047] When the first partition 9 moves, the two spring sleeves 19 will extend and shorten accordingly, so that the receiving seat 5 is always in the middle position of the machine tool 1 to support the product, prevent the product from bending due to excessive length, and improve the production quality of the product.

[0048] like Figure 6As shown, a retaining ring 20 is installed in the positioning hole 3. A pressure sensor 21 is installed on the side of the retaining ring 20 near the receiving seat 5. The pressure sensor 21 is electrically connected to the drilling rotary cutter 8, the clamping electric telescopic rod 10 and the fixing half ring 6.

[0049] When the electric telescopic rod 10 is pressed to push the product to move, the pressure sensor 21 will send an electrical signal when it detects that the product has reached the processing position. This will control the electric telescopic rod 10 to stop retracting, preventing the product from being squeezed and deformed. At the same time, it will ensure that both ends of the product are supported and fixed, thus improving production quality. The electrical signal will also control the hinge mechanism of the fixed half ring 6 to operate, so that the fixed half ring 6 is combined with the receiving seat 5 to grip the product and prevent shaking during processing.

[0050] The machine tool 1 is equipped with a post-processing component 22, a filtering component 23, and a cleaning component 24;

[0051] Post-processing component 22 can clean the inner hole of the screw after drilling;

[0052] The filter assembly 23 uses the discharge from the screw to filter and reuse the cleaning liquid;

[0053] Cleaning component 24 can enhance the cleaning effect of post-treatment component 22.

[0054] like Figures 1-4 , Figure 7 and Figures 10-12 As shown, the post-processing assembly 22 includes a mounting base 2201, an electric telescopic base 2202, a robotic arm 2203, a central shaft plate 2204, a module slide rail 2205, a first slider 2206, a first motor 2207, a cleaning rod 2208, a processing nozzle 2209, a wiping ring 2210, a liquid storage tank 2211, a liquid pump 2212, a two-way valve 2213, a first branch pipe 2214, a second branch pipe 2215, and a discharge chute 2216;

[0055] Machine tool 1 is equipped with a mounting base 2201, on which an electric telescopic base 2202 and a robotic arm 2203 are mounted. The robotic arm 2203 is electrically connected to the drilling rotary cutter 8. A central shaft plate 2204 is mounted on the mounting base 2201. A module slide rail 2205 is also mounted on the mounting base 2201. A first slider 2206 is slidably mounted on the module slide rail 2205. A first motor 2207 is mounted on the first slider 2206. A cleaning rod 2208 is mounted on the output shaft of the first motor 2207. A treatment nozzle 2209 and a wiping ring are mounted at the end of the cleaning rod 2208. 2210, the wiping ring 2210 is closer to the first motor 2207 than the treatment nozzle 2209. The mounting base 2201 is equipped with a liquid storage tank 2211, and the liquid pump 2212 is installed in the liquid storage tank 2211. The output end of the liquid pump 2212 is equipped with a two-way valve 2213. The output end of the two-way valve 2213 is equipped with a first branch pipe 2214 and a second branch pipe 2215 respectively. The first branch pipe 2214 connects the two-way valve 2213 to the liquid delivery channel in the cleaning rod 2208 and is connected to the treatment nozzle 2209. The mounting base 2201 is provided with a discharge trough 2216.

[0056] After drilling is completed, the robotic arm 2203 picks up the product and places it on the electric telescopic seat 2202. Then, the first module slide rail 2205, the first motor 2207, and the liquid pump 2212 operate. The first slider 2206 moves along the first module slide rail 2205 towards the central shaft plate 2204. The liquid pump 2212 supplies liquid to the treatment nozzle 2209. The first motor 2207 drives the treatment nozzle 2209 and the wiping ring 2210 to move synchronously via the cleaning rod 2208, cleaning the residual waste inside the product. The cleaning process involves the spray nozzle 2209 washing away debris adhering to the hole wall. Under the pushing action of the wiping ring 2210, the cleaning fluid and debris flow out from the other end of the product. The cleaned rod 2208 returns to its initial position along with the first slider 2206 and controls the extension of the electric telescopic seat 2202 near the central shaft plate 2204, causing the product to tilt and fall into the discharge trough 2216. This ensures the cleanliness of the product hole and achieves automatic unloading, improving production efficiency while ensuring product quality.

[0057] The post-treatment assembly 22 also includes a rotating ring 2217. The rotating ring 2217 is rotatably mounted on the cleaning rod 2208. The rotating ring 2217 connects the first branch tube 2214 and the infusion channel. Both the first branch tube 2214 and the second branch tube 2215 are flexible tubes.

[0058] When the cleaning rod 2208 is in the post-processing stage, it is in a rotating device. Simple pipe connections may cause the first branch pipe 2214 to become entangled. The swivel ring 2217 can ensure the normal operation of the equipment.

[0059] like Figures 1-3 and Figures 8-9As shown, the filter assembly 23 includes a slide 2301, a second slider 2302, an outlet baffle 2303, a first screw 2304, a mounting plate 2305, a slide rod 2306, a connecting rod 2307, a return spring 2308, a drive gear 2309, a driven gear 2310, a transmission rod 2311, a second screw 2312, a transmission belt 2313, a connecting frame 2314, a filter tank 2315, a disturbance plate 2316, a filter plate 2317, and a return channel 2318.

[0060] A slide groove 2301 is provided on the side wall of the discharge chute 2216. A second slider 2302 is slidably installed in the slide groove 2301. An outlet baffle 2303 is installed on the side of the second slider 2302 near the discharge chute 2216. A first screw 2304 and a mounting plate 2305 are rotatably installed in the mounting base 2201. The first screw 2304 and the mounting plate 2305 are rotatably connected. A slide rod 2306 is slidably installed on the first screw 2304. A connecting rod 2307 is slidably installed on the slide rod 2306. The slide rod 2306 and the second slider 2302 are connected through the connecting rod 2307. The lower end of the slide rod 2306 is connected to the mounting base 2201 through a return spring 2308. The lower part of the mounting plate 2305... A drive gear 2309 is installed, and a transmission rod 2311 is rotatably installed inside the mounting base 2201. A driven gear 2310 is installed on the transmission rod 2311, and the driven gear 2310 meshes with the drive gear 2309. A second screw 2312 is installed on the mounting base 2201, and the second screw 2312 is connected to the transmission rod 2311 through a transmission belt 2313. A filter groove 2315 is opened on the mounting base 2201, and a filter plate 2317 is installed in the filter groove 2315. The filter groove 2315 is connected to the liquid storage tank 2211 through a return groove 2318. A connecting frame 2314 is slidably installed on the second screw 2312, and a disturbance plate 2316 is installed at the end of the connecting frame 2314.

[0061] When the post-processed product falls into the discharge trough 2216 and slides downwards, it pushes the outlet baffle 2303 to slide synchronously. The outlet baffle 2303 will drive the slide rod 2306 to move vertically through the second slider 2302 and the connecting rod 2307. The displacement of the slide rod 2306 will cause the first screw 2304 to rotate. The drive gear 2309 meshes with the driven gear 2310. The first screw 2304 drives the driven gear 2310 to rotate through the drive gear 2309. The driven gear 2310 drives the second screw 2312 to rotate through the transmission rod 2311 and the transmission belt 2313. The second screw 2312 is a reciprocating screw. The rotation of the second screw 2312 will cause the connecting frame 2314 to move reciprocally. The connecting frame 2314 will drive the disturbance plate 2316 to turbulent the used cleaning liquid in the filter tank 2315, preventing waste debris from accumulating and clogging the filter plate, and improving the filtration efficiency of the waste liquid.

[0062] When the product slides down and causes the slide bar 2306 to move downward, the slide bar 2306 will compress the return spring 2308. The elastic potential energy of the return spring 2308 increases, which generates a gradually increasing supporting force on the slide bar 2306, slowing down the falling speed of the slide bar 2306. The slower falling speed of the slide bar 2306 means that the product's sliding speed in the discharge chute 2216 is slowed down, which can prevent the product from being damaged by impact force when sliding down, and can improve product quality.

[0063] like Figure 1 , Figure 7 and Figures 10-11 As shown, the cleaning assembly 24 includes an airbag groove 2401, a second partition 2402, a third partition 2403, a first airbag 2404, a second airbag 2405, a temporary water tank 2406, a second motor 2407, a rotating frame 2408, a cleaning sleeve 2409, and a push plate 2410.

[0064] An airbag groove 2401 is installed on the mounting base 2201. A second partition 2402 and a third partition 2403 are installed inside the airbag groove 2401. A push plate 2410 is installed on the first slider 2206. The push plate 2410 is connected to the second partition 2402 through a first airbag 2404. The second partition 2402 and the third partition 2403 are connected through a second airbag 2405. A temporary water tank is installed at the end of the airbag groove 2401 near the second airbag 2405. 2406, temporary water tank 2406 is connected to the second branch pipe 2215, the valve port of the double-way valve 2213 connected to the second branch pipe 2215 is opened at a time, the second motor 2407 is installed on the mounting base 2201, the rotating frame 2408 is installed on the output shaft of the second motor 2407, the cleaning sleeve 2409 is installed on the rotating frame 2408, the cleaning sleeve 2409 is provided with a cleaning nozzle, and the infusion pipe of the cleaning nozzle is connected to the temporary water tank 2406.

[0065] The output port of the second airbag 2405 is the outlet of the pressure valve, and the output port of the second airbag 2405 is electrically connected to the second motor 2407. The temporary water tank 2406 is slidably installed on the wall of the temporary water tank 2406 near the second partition 2402.

[0066] After the wiping ring 2210 cleans the inside of the product, waste will accumulate on the side of the wiping ring 2210 near the discharge trough 2216. When the wiping ring 2210 returns to its initial position, the waste is very likely to stick back into the product, affecting the treatment effect.

[0067] As the first slider 2206 moves closer to the central shaft plate 2204, it compresses the first airbag 2404 via the push plate 2410. The gas inside the first airbag 2404 is forced into the second airbag 2405, increasing the air pressure within it. When the wiping ring 2210 reaches the end of the product, the air pressure inside the second airbag 2405 reaches the outlet threshold, causing the outlet of the second airbag 2405 to open and begin venting. Simultaneously, the second motor 2407... The forward rotation causes the cleaning sleeve 2409 to be positioned coaxially with the cleaning rod 2208. As the cleaning rod 2208 continues to move, the wiping ring 2210 enters the cleaning sleeve 2409. The gas discharged from the second airbag 2405 pushes the cleaning fluid in the temporary water tank 2406 to spray out from the cleaning sleeve 2409, cleaning the wiping ring 2210 and keeping it clean. This prevents the wiping ring 2210 from causing secondary contamination to the product during its return stroke, further improving product quality.

[0068] The valve port connected to the double-way valve 2213 and the second branch pipe 2215 is opened at a time to prevent excessive cleaning fluid in the temporary water tank 2406 from overflowing. At the same time, the pressurized water supply through the air pressure in the second airbag 2405 can prevent waste of cleaning fluid caused by direct continuous water supply.

[0069] The working principle of this invention is as follows: Inside the feeding frame 11, the product inside the feeding frame 11 is ensured to fall one by one to the processing position by the alternating extension of the feeding baffle 17 of the baffle rod 15, thereby realizing automatic feeding and improving production efficiency and production safety.

[0070] After the drilling process is completed, waste residue will remain inside the product holes. The cleaning rod 2208 drives the treatment nozzle 2209 and the wiping ring 2210 to rotate and move, so as to clean the waste residue inside the holes in time and improve product quality.

[0071] After the cleaning liquid from the waste material inside the hole flows into the filter tank 2315, it can be filtered and reused. However, the accumulation of waste material particles will clog the filter plate 2317. The gravity of the product during feeding drives the agitator plate 2316 to agitate the waste liquid back and forth, reducing the sedimentation effect of the waste material and ensuring the filtration efficiency of the waste liquid.

[0072] After the wiping ring 2210 cleans the inside of the product, waste material will accumulate on the side of the wiping ring 2210 near the discharge trough 2216. When the wiping ring 2210 returns to its initial position, the waste material is very likely to re-adhere to the product, affecting the treatment effect. Through the control of the first airbag 2404 and the second airbag 2405, the cleaning sleeve 2409 is positioned coaxially with the cleaning rod 2208 before the wiping ring 2210 extends out of the product. This allows the wiping ring 2210 to be inserted into the cleaning sleeve for rinsing and cleaning, preventing secondary contamination of the product when the wiping ring 2210 returns, and further improving product quality. Pressurized water supply through the air pressure in the second airbag 2405 can prevent waste of cleaning solution caused by direct continuous water supply.

[0073] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
