Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of double-head row cutter machine tools, in particular to a middle-drive flat rail double-head row cutter machine tool. BACKGROUND

[0002] The flat rail double-head row cutter machine tool is a high-efficiency precision machining equipment, the bed body of which adopts two parallel linear guides to ensure smooth and rigid operation of the sliding table; one set of independent cutter system is arranged at each end of the machine tool, which can simultaneously cut the workpiece synchronously, so as to double the machining efficiency per unit time; at the same time, a plurality of cutters are arranged along the longitudinal sliding table, which can be flexibly combined or quickly switched according to the process requirements, thereby reducing the auxiliary time for tool changing. The overall structure is compact, and it is particularly suitable for continuous production of large quantities of high-precision parts, and is usually equipped with a perfect chip removal and cooling system to cope with the problem of a large amount of chips and temperature rise caused by high-speed cutting, so as to ensure long-term stable operation.

[0003] During the continuous operation of the double-head row cutter machine tool, the left and right cutter holders participate in cutting synchronously, so that the metal removal amount per unit time is doubled, and a large amount of machining chips is generated. In order to suppress temperature rise and assist in chip removal, cutting fluid is continuously and high-pressure poured into the cutting area, although most of the chips can be quickly separated from the machining position with the help of liquid flow impact, but the fine chips are not simply washed away by the liquid flow, but are diffused and selectively retained with the liquid flow, which makes it extremely difficult to clean the subsequent chips. SUMMARY

[0006] By adopting the above technical scheme, by equidistantly arranging a plurality of ribs in two rows and fixedly connecting them to the bottoms of two passages, flow channels with equal width are formed between adjacent ribs, the uniformity and stability of the flow of cleaning liquid in each flow channel are ensured, flow deviation and scouring dead zones caused by different flow channel widths are effectively avoided, and in combination with the dispersion box structure with narrow upper part and wide lower part, the flow velocity slows down when the cutting fluid flows into the flow channel from the passage through the dispersion box due to the gradual expansion of the flow cross section, splashing and flow deviation caused by high-speed impact of the cleaning liquid are avoided, the cleaning liquid enters each flow channel in a stable laminar flow state, and full-coverage efficient scouring of the top of the machine tool bed is realized.

[0007] In a preferred example, the utility model can be further configured as: a plurality of ribs are equidistantly arranged in two rows, and the two rows of ribs are respectively located at the bottoms of the two passages, and the top ends of the ribs are fixedly connected to the bottoms of the passages.

[0008] In a preferred example, the utility model can be further configured as: the dispersion box is narrow at the top and wide at the bottom, and the inside of the passage is communicated with the inside of the flow channel through the dispersion box.

[0009] In a preferred example, the utility model can be further configured as: the bottom of the machine tool bed is provided with a solid-liquid separation mechanism, the solid-liquid separation mechanism includes a slag discharge opening opened in the inner bottom surface of the machine tool bed, a support frame fixedly connected to the bottom of the machine tool bed, two filter screens respectively fixedly embedded in the inside two side walls of the support frame, and two liquid cavities opened in the inside of the support frame.

[0010] In a preferred embodiment, the present invention can be further configured such that two baffles are fixedly connected between the two channels, and the outer wall of the baffles is in contact with the inner wall of the machine tool bed.

[0011] In a preferred embodiment, the present invention can be further configured such that: the bottom surface of the table frame has an opening, the opening being located between two liquid tanks.

[0012] In a preferred embodiment, the present invention can be further configured such that: a mesh is provided at the top of the liquid tank, and the bottom of the mesh is fixedly connected to the inner bottom surface of the table frame.

[0014] In a preferred embodiment, the present invention may be further configured such that: the scraper is composed of a metal strip and a rubber strip, the length of the metal strip is greater than the length of the rubber strip, the rubber strip is fixed to the bottom of the metal strip and fits against the inner bottom surface of the table frame.

[0015] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows: 1. In this invention, by arranging multiple ribs at equal intervals in two rows and fixing them to the bottom of two channels respectively, a flow channel with equal width is formed between adjacent ribs. This ensures the uniformity and stability of the cleaning fluid flow in each flow channel, effectively avoiding flow deviation and scouring dead zones caused by inconsistent flow channel widths. At the same time, in conjunction with the dispersion box structure that is narrow at the top and wide at the bottom, the flow velocity of the cutting fluid is slowed down as it flows from the channel through the dispersion box into the flow channel due to the gradual expansion of the flow cross section. This avoids splashing and deflection caused by high-speed impact of the cleaning fluid, ensuring that the cleaning fluid enters each flow channel in a stable laminar flow state, thereby achieving full-coverage and efficient scouring of the top of the machine tool bed.

[0016] 2. In this invention, by opening an opening in the inner bottom surface of the table frame and setting the external thread of the threaded rod to a structure with two sections of opposite rotation, two scrapers are driven to move towards each other on the inner bottom surface of the table frame. This directly pushes the chip mixture to the opening, effectively preventing the accumulation of chips on both sides of the inner bottom surface of the table frame, ensuring thorough and efficient chip removal. On the other hand, by setting a chip removal port, filter screen, and liquid chamber at the bottom of the machine tool bed, the discharged chip and cutting fluid mixture enters the support frame through the chip removal port and then passes through the filter screen to achieve solid-liquid separation. The retained chips are easy to collect and clean, while the filtered cutting fluid can be recycled through the liquid chamber, which reduces the cost of using cutting fluid and avoids environmental pollution caused by chip-containing cutting fluid.

[0017] 3. In this invention, by fixing a baffle between the two channels and making the outer wall of the baffle fit against the inner wall of the machine tool bed, the cleaning fluid is limited and guided by the baffle when flowing on the top of the machine tool bed, preventing the cleaning fluid from flowing directly from the edges of both sides of the machine tool bed without effective rinsing, thereby prolonging the contact time between the cleaning fluid and the adsorbed debris, and significantly improving the cleaning effect of a single rinse.

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0021] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0022] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a mid-drive, flat-rail, double-headed tool machine.

[0023] Example 1: Combining Figures 1-7 As shown, the present invention provides a mid-drive flat-rail double-headed tooling machine tool, including a machining mechanism 100, a flow guiding mechanism 200, and a liquid supply mechanism 300. The machining mechanism 100 includes a machine bed 110, two guide rails 120 fixedly connected to the top of the machine bed 110, two servo motors 130 respectively fixedly connected to both ends of the machine bed 110, two transverse slides 140 slidably connected between the two guide rails 120, a longitudinal slide 150 slidably connected to the top of the transverse slides 140, a plurality of tool fixture assemblies 160 slidably connected to the top of the longitudinal slides 150, a stroke stop 170 disposed between the two longitudinal slides 150 and fixedly connected to the top of the machine bed 110, a rotary assembly 180 mounted on the top of the stroke stop 170, and a motor body 190. The transverse slides 140 are movably connected to the servo motors 130. The flow guiding mechanism 200 includes two channels 210 and a plurality of ribs 220 that are respectively fixed to the inner side walls of the machine tool bed 110, a flow channel 230 that runs between two adjacent ribs 220, and a plurality of dispersion boxes 240 that pass through the bottom of the channel 210. The plurality of dispersion boxes 240 are respectively located inside the plurality of flow channels 230. The liquid supply mechanism 300 includes two tables 310 respectively attached to both sides of the stroke stop 170 and fixed between two guide rails 120, two liquid tanks 320 opened on the inner bottom surface of the tables 310, two outlet pipes 330 fixedly penetrating the inner bottom surface of the liquid tanks 320, a threaded rod 340 rotatably installed inside the tables 310, a motor 350 fixed between the tables 310 and the threaded rod 340, and a scraper 360 slidably installed inside the tables 310. The scraper 360 is threadedly sleeved on the outside of the threaded rod 340, and the external thread of the threaded rod 340 is set to two segments with opposite directions of rotation.

[0024] Furthermore, multiple ribs 220 are arranged at equal intervals in two rows, with the two rows of ribs 220 located at the bottom of two channels 210 respectively. The tops of the ribs 220 are fixed to the bottom of the channels 210. By arranging multiple ribs 220 at equal intervals in two rows and with the two rows of ribs 220 located at the bottom of two channels 210 respectively, and fixing the tops of the ribs 220 to the bottom of the channels 210, flow channels 230 of equal width are formed between adjacent ribs 220. This ensures the uniformity and stability of the cleaning fluid flow in each flow channel 230, avoids flow deviation and scouring dead zones caused by the different widths of the flow channels 230, and achieves full-coverage cleaning of the top of the entire machine tool bed 110.

[0025] Furthermore, the dispersion box 240 is narrower at the top and wider at the bottom, and the interior of the channel 210 is connected to the interior of the flow channel 230 through the dispersion box 240. By setting the dispersion box 240 to a structure that is narrower at the top and wider at the bottom, and by connecting the interior of the channel 210 to the interior of the flow channel 230 through the dispersion box 240, the flow rate of the cutting fluid flowing from the channel 210 into the flow channel 230 is slowed down due to the gradual expansion of the flow cross section. This avoids splashing and deflection caused by the high-speed impact of the cleaning fluid, ensuring that the cleaning fluid enters each flow channel 230 in a stable laminar flow state, thereby improving the rinsing efficiency.

[0026] Furthermore, the inner bottom surface of the table frame 310 is provided with an opening 600, which is located between two liquid tanks 320. When the scraper 360 moves towards each other under the drive of the threaded rod 340, it can directly push the debris mixture to the opening 600, avoiding the accumulation of debris on both sides of the inner bottom surface of the table frame 310, realizing the centralized discharge of debris, and ensuring the thoroughness and efficiency of debris removal.

[0027] Furthermore, a mesh 700 is provided on the top of the liquid tank 320, and the bottom of the mesh 700 is fixed to the inner bottom surface of the table frame 310. The mesh 700 is used to pre-filter the cleaning liquid entering the liquid tank 320, intercepting large particles of chips and impurities, preventing them from entering the outlet pipe 330 and channel 210 with the cleaning liquid and causing blockage. This ensures the long-term smooth operation of the entire flow guiding mechanism 200 and reduces the frequency and cost of equipment maintenance.

[0028] Furthermore, two adjacent outlet pipes 330 are arranged opposite each other, and the bottom end of the outlet pipe 330 extends movably into the interior of the channel 210. By arranging the two adjacent outlet pipes 330 opposite each other and extending the bottom end of the outlet pipe 330 into the interior of the channel 210, the two streams of cleaning fluid form opposing impacts inside the channel 210, generating a turbulent effect. This promotes more thorough mixing of the cutting fluid and uniform dispersion into each dispersion box 240, avoiding the problem of excessive flow in the flow channel 230 near the outlet pipe 330 and insufficient flow in the flow channel 230 away from the outlet pipe 330 due to fluid supply from only one side of the outlet pipe 330, thus ensuring balanced flow in each flow channel 230.

[0029] Furthermore, the scraper 360 is composed of a metal strip 361 and a rubber strip 362. The length of the metal strip 361 is greater than the length of the rubber strip 362. The rubber strip 362 is fixed to the bottom of the metal strip 361 and fits against the inner bottom surface of the table frame 310. The metal strip 361 provides sufficient structural strength and threaded connection rigidity to ensure the dimensional and positional stability of the scraper 360 during long-term reciprocating motion. The rubber strip 362 uses its elastic deformation ability to fit tightly against the inner bottom surface of the table frame 310, effectively scraping away the debris and slurry adhering to the inner bottom surface, while avoiding scratches and wear caused by rigid contact to the inner bottom surface of the table frame 310.

[0030] Example 2: Combination Figure 1 and Figure 6 As shown, based on Embodiment 1, the machine tool bed 110 is provided with a solid-liquid separation mechanism 400 at its bottom. The solid-liquid separation mechanism 400 includes a slag discharge port 410 opened on the inner bottom surface of the machine tool bed 110, a support frame 420 fixedly connected to the bottom of the machine tool bed 110, two filter screens 430 respectively fixedly embedded in the inner side walls of the support frame 420, and two liquid cavities 440 opened inside the support frame 420. By setting the solid-liquid separation mechanism 400 at the bottom of the machine tool bed 110, that is, opening the slag discharge port 410 on the inner bottom surface of the machine tool bed 110 and cooperating with the filter screens 430 and liquid cavities 440 inside the support frame 420, the discharged chips and cutting fluid mixture enter the support frame 420 through the slag discharge port 410 and then pass through the filter screens 430 to achieve solid-liquid separation. The retained chips are easy to collect and clean, and the filtered cutting fluid can be recycled through the liquid cavities 440. This reduces the cost of using cutting fluid and avoids the pollution of the environment by the chip-containing cutting fluid.

[0031] Example 3: Combination Figure 4 As shown, in the above embodiment, two baffles 500 are fixed between the two channels 210. The outer wall of the baffles 500 is in contact with the inner wall of the machine tool bed 110. By fixing the two baffles 500 between the two channels 210 and making the outer wall of the baffles 500 in contact with the inner wall of the machine tool bed 110, the cleaning fluid is limited and guided by the baffles 500 when flowing at the top of the machine tool bed 110. This prevents the cleaning fluid from flowing directly from the two sides of the machine tool bed 110 without effective rinsing, prolongs the contact time between the cleaning fluid and the adsorbed debris, and significantly improves the cleaning effect of a single rinse.

[0032] Working principle and usage process of this invention: Preparation: The workpiece to be processed is clamped on the rotary assembly 180. The rotary assembly 180 is driven by the motor body 190 to rotate the workpiece. According to the processing requirements, the corresponding cutting tools are installed on the tool fixture assembly 160. The tools at the left and right ends are adjusted to the processing position through the coordinated movement of the transverse slide 140 and the longitudinal slide 150.

[0033] Machining process: The servo motor 130 is started to drive the transverse slide 140 to make transverse feed motion along the guide rail 120. At the same time, the longitudinal slide 150 makes longitudinal compensation motion to realize the synchronous cutting of the workpiece by the tools at both ends. At this time, the cutting fluid cools the tools and workpiece in real time. Then, a large number of chips generated during the machining process are scattered on the top of the two table frames 310 along with the cutting fluid.

[0034] Cleaning and chip removal process: The cutting fluid mixed with chips is then filtered through the mesh 700 and enters the outlet pipe 330. After entering the channel 210, the cutting fluid is divided by multiple dispersion boxes 240. Then, the cutting fluid flows along the flow channel 230 formed between adjacent ribs 220, forming multiple parallel and stable cleaning fluid flows on the top of the machine tool bed 110, which thoroughly rinses the surface of the machine tool bed 110. At the same time, the baffle 500 prevents the cleaning fluid from flowing out from both sides of the machine tool bed 110 without sufficient rinsing, ensuring that the cleaning fluid forms an effective coverage along the preset path.

[0035] During this process, the motor 350 drives the threaded rod 340 to rotate. Since the external thread of the threaded rod 340 is set in two sections with opposite directions of rotation, the two scrapers 360 move towards each other along the inner bottom surface of the table frame 310 under the thread drive. This pushes the mixture of debris and cutting fluid that has been flushed and collected inside the table frame 310 toward the opening 600, allowing the debris to fall off quickly. Then, in conjunction with the stable flow of the cleaning fluid, the debris can be quickly flushed into the slag discharge port 410, thereby achieving rapid cleaning of the debris.

[0036] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
