Description

Technical Field

[0001] This invention belongs to the technical field of chip removal structure in machining centers, and specifically relates to a rapid chip removal structure for gantry machining centers. Background Technology

[0002] As large-scale precision metal processing equipment, gantry machining centers generate a large amount of mixed waste material of iron filings and coolant during the cutting process. Existing chip removal structures generally suffer from the following defects: the machining table is mostly horizontally fixed or inconveniently adjustable, iron filings rely on manual sweeping or passive scraper pushing, easily accumulating in dead corners of the table, resulting in low chip removal efficiency and frequent machine shutdowns; the iron filings and coolant are directly discharged after mixing, lacking efficient solid-liquid separation methods, leading to low coolant recovery rates, environmental pollution, and high subsequent iron filings treatment costs; chip removal power relies solely on gravity, which is prone to interruption during long-distance transport, requiring additional manual intervention and affecting the equipment's continuous operation capability. These shortcomings limit the production efficiency of gantry machining centers, increase maintenance costs, and make it difficult to meet the demands of modern high-efficiency machining. Summary of the Invention

[0003] The purpose of this invention is to provide a rapid chip removal structure for gantry machining centers to solve the aforementioned problems. Through a rotatable connection between the bearing housing and the base, and in conjunction with a sliding groove, trapezoidal slider, and threaded rod adjustment mechanism, the tilt angle can be flexibly adjusted, allowing iron chips to actively collect in the guide channel under gravity, improving chip removal conditions from the source. The adjustable tilt angle design can also adapt to the chip removal requirements of different workpieces, preventing iron chips from accumulating. The end of the spiral feed pipe guides the iron chips into a waste press for compression through a slag discharge port, while the top liquid outlet pipe guides the coolant into a coolant filter box. Inside the filter box, a guide channel guides the liquid flow; after the filter plate intercepts impurities, the clean coolant is recycled through a guide channel and a recovery pipe, achieving solid-liquid separation and coolant reuse, reducing resource consumption and environmental pollution. The overall structure integrates chip removal, conveying, separation, and recovery functions, reducing manual intervention. The modular design of components such as the spiral feed rod and servo motor facilitates maintenance, and the adjustment mechanism is easy to operate, significantly shortening the chip removal cycle and improving the continuous operation capability of the equipment. It is suitable for high-intensity production scenarios in gantry machining centers.

[0014] like Figure 1-4 As shown, this specific embodiment adopts the following technical solution: a rapid chip removal structure for a gantry machining center, comprising: Base 1 and processing table 2: The base 1 has 4 M20 anchor bolt holes at the bottom and the top surface is milled.

[0015] The table surface of the machining table 2 has a T-slot. One end of the bottom of the machining table is rotatably connected to the base through a bearing seat 8. A bearing mounting seat is welded to the bottom of the machining table. The bearing seat is fixed to the top surface of the base by bolts. The bottom shaft end of the machining table is interference-fitted with the inner ring of the bearing.

[0016] Guide channel 9 and spiral feed pipe 10: The guide groove 9 is tilted at an angle of 15° and is welded to the end of the processing table near the bearing seat 8 by an L-shaped bracket. The bottom of the groove is flush with the surface of the processing table, and the edge of the groove is rounded to avoid scratches.

[0017] The spiral feeding pipe 10 is made of seamless steel pipe with an inclination angle of 20°. It is supported by a bracket and placed below the inclined lower end of the guide channel 9. The spiral feeding pipe is equipped with a spiral feeding rod inside.

[0018] Machining table angle adjustment mechanism; Slide 4 and trapezoidal slider 7: The top of the base 1 away from the bearing seat 8 is fixed with a bolt to slide 4. A guide groove 3 is opened at the corresponding position on the bottom of the processing table 2. The trapezoidal slider 7 is placed in the slide, and its inclined surface slides in contact with the guide groove 3 to achieve guidance when the processing table is tilted.

[0019] Threaded rod 6 and crank handle 5: The threaded rod 6 is rotatably connected to both ends of the slide groove 4 through bearings. The threaded rod passes through the threaded hole of the trapezoidal slider 7, forming a threaded drive. The crank handle 5 is fixed to the outer end of the slide groove 4 through a key. The crank handle's rotating shaft is coaxial with the threaded rod. Manually turning the crank handle can drive the trapezoidal slider 7 to move linearly within the slide groove, thereby adjusting the tilt angle of the processing table 2.

[0020] Spiral feed pipe power and chip / liquid discharge system; Servo motor 12 and feed hopper 11: The feed hopper 11 is welded to the top of the inclined upper end of the spiral feeding pipe 10, and a vibrator mounting seat is provided on the hopper wall. The servo motor 12 is fixed to the outer end of the spiral feeding pipe 10 through a flange, and the motor output shaft is connected to the outer end of the spiral feeding rod through a flexible coupling to drive the spiral feeding rod to rotate.

[0021] Slag discharge port 13 and waste press 15: The bottom of the inclined upper end of the spiral feed pipe 10 is provided with a slag discharge port 13, which is directly opposite the feed port of the waste press 15. A chute is provided between the slag discharge port and the waste press to guide the iron filings to fall.

[0022] Liquid outlet pipe 14 and coolant filter box 16: The liquid outlet pipe 14 is welded to the bottom of the inclined lower end of the spiral feed pipe 10, and the coolant filter box 16 is located directly below it.

[0023] Flow guide trough 18 and filter plate 21: Flow guide trough 18 is symmetrically welded on both sides inside the box. Filter plate 21 is installed at the top opening of the trough by a snap fastener. The filter plate can be quickly disassembled and cleaned.

[0024] Drainage channel 19 and recovery pipe 20: Drainage channel 19 is opened at the lowest point of the bottom of the guide channel 18, and recovery pipe 20 is welded to the end of the drainage channel. It is connected to the coolant tank of the machining center through a hose to realize recycling.

[0025] Specifically: A rapid chip removal structure for a gantry machining center. In use, depending on the type of workpiece being processed, the crank handle 5 is manually turned to drive the threaded rod 6 to rotate, which in turn drives the trapezoidal slider 7 to move towards the front or rear end of the base within the slide groove 4. Through the guide groove 3, the machining table 2 is pushed to rotate around the bearing seat 8 until the target angle is reached.

[0026] During the processing, the mixture of iron filings and coolant slides from the surface of the processing table 2 to the guide channel 9. Because the guide channel is tilted at 15°, the mixture flows to the lower tilted end under the action of gravity and enters the feed hopper 11 of the spiral feed pipe 10.

[0027] Servo motor 12 starts and drives the spiral feed rod to rotate clockwise. The iron filings move upward along the spiral feed tube 10 under the push of the spiral blades. After reaching the inclined upper end, they fall from the slag discharge port 13 into the waste press 15 material box. The waste press compresses the iron filings into blocks, which are easy to collect.

[0028] The coolant mixed with iron filings is subjected to centrifugal force and gravity within the spiral feed pipe 10, seeping out from the gaps between the iron filings and finally flowing from the outlet pipe 14 into the guide trough 18 of the coolant filter tank 16. After being filtered by the filter plate 21, the coolant flows into the diversion trough 19 at the bottom of the guide trough, and is then pumped back to the machining center coolant tank for reuse through the recovery pipe 20.

[0029] Regularly open the filter box, remove the filter plate 21 and clean the iron filings accumulated on the surface; when the waste press 15 hopper is full, start the compression program to push out the iron filings and replace the hopper with a new one; if the screw feed rod is severely worn, it can be replaced by disassembling it through the flange.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the present invention.
