Description

Technical Field

[0001] This invention relates to the field of machine tool technology, specifically to a gantry-type five-sided machining center. Background Technology

[0002] A gantry-type five-sided machining center is a large CNC machine tool based on a gantry structure, capable of simultaneously or separately performing high-precision machining operations such as milling, boring, and drilling on five sides of a workpiece. Its core advantages are reflected in the following two aspects: Wide machining range: It can complete multi-sided machining of complex workpieces in one operation, reducing the number of workpiece clamping operations and lowering positioning errors; High stability: The gantry frame structure has high rigidity, making it suitable for machining large and heavy workpieces, ensuring accuracy and stability during the machining process.

[0003] Chinese patent application CN118905647B discloses a single-sided horizontal boring and milling composite machining center with a fixed beam, relating to the field of composite boring and milling machine tools. It includes a slide rail table with a placement platform mounted on top. A vertical boring and milling device is slidably mounted on one side of the slide rail table, and a horizontal boring and milling device is slidably mounted on the other side of the slide rail table. Side plates are fixed at both ends of the slide rail table. Compared to existing technologies, the protective components can enclose the entire linear slide rail table, preventing debris from splashing during boring and milling. The oscillating airflow of the blowing component blows the debris into the collection grooves on both sides of the slide rail table. When the protective film is opened, the debris is pushed to one side, facilitating cleaning of the debris on the slide rail table. It also facilitates manual cleaning of the debris generated during boring and milling, preventing debris from falling into the environment and affecting the environment during the boring and milling process.

[0004] In the aforementioned patent, the gantry machining center uses protective films on the front and rear sides of the machine tool to prevent debris from flying out. Fans on the front and rear sides of the machine tool blow debris into the collection slots on the front and rear sides. However, because the fans have limited lateral movement due to the telescopic rods, some debris accumulates at the edges of the maximum blowing range of the fans on the left and right sides inside the machine tool, making it difficult to clean thoroughly. Furthermore, when cutting fluid is used during machining, some debris containing the fluid adheres to the front and rear protective films, making them difficult to clean. The protective films are also damaged during subsequent winding due to the inclusion of debris. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of incomplete chip removal, difficulty in cleaning adhered chips, and easy damage to protective mechanisms in general gantry machining centers during use. This invention provides a gantry-type five-sided machining center.

[0006] To achieve the above objectives, the present invention specifically adopts the following technical solution: A gantry-type five-sided machining center includes a bed, with a chip collection groove and a liquid collection chamber respectively provided on the left side and bottom of the bed.

[0009] Furthermore, a shaft block is fixedly connected to the inner wall of the bed and rotatably connected to the top of the torque shaft, and a spiral spring is provided between the torque shaft and the shaft block.

[0010] Furthermore, the barrier is made of nylon canvas and its surface can be coated with PVC or polyurethane material.

[0011] Furthermore, a pin is fixedly connected to the bottom of the rotating plate, a sliding frame is slidably connected to the lower wall of the inner cavity of the mounting platform and is movably engaged with the pin, and a multi-stage telescopic cylinder with its telescopic end engaged with the sliding frame is fixedly connected to the front wall of the inner cavity of the mounting platform, and the rear end of the multi-stage telescopic cylinder has an anti-detachment block.

[0012] Furthermore, the drive assembly includes an L-shaped elastic bent rod that is slidably engaged with the inner wall of the right side of the mounting platform. The filter channel is fixedly connected to the elastic bent rod. A pin is fixedly connected to the bottom of the elastic bent rod and slidably connected to the lower wall of the inner cavity of the mounting platform. A toothed plate passing through the slide frame is slidably engaged with the lower wall of the inner cavity of the mounting platform. The bottom of the toothed plate has a through groove adapted to the pin. The lower wall of the through groove has an inclined groove that is movably engaged with the pin. An electromagnetic block is fixedly connected to the upper wall of the middle of the slide frame. An elastic magnetic wedge is slidably engaged with the inner wall of the middle of the slide frame. Several slots are linearly opened on the surface of the toothed plate to movably engage with the elastic magnetic wedge. A worm gear is rotatably connected to the right wall of the bed. The worm gear is driven by a forward and reverse motor installed on the front wall of the bed. A cam that movably abuts against the elastic bent rod is fixedly sleeved in the middle of the worm gear.

[0013] Furthermore, the drive assembly also includes rollers rotatably connected to the left and right walls of the bed, with transmission belts movably sleeved at both ends of the upper and lower rollers on the front and rear sides. The slide is fixedly connected to the transmission belts, and a worm gear meshing with a worm is fixedly sleeved at the right end of the lower roller.

[0016] The beneficial effects of this invention are as follows: This invention controls the rotating plate to deflect towards the center, causing the baffle to form a triangular guide zone on the left and right sides of the mounting table. In conjunction with the gantry frame driving the universal machining mechanism, the air jet disc follows and blows the workpiece, making it easier to blow debris into the filter channels on both sides. Furthermore, the drive assembly drives the rotating plate and baffle to vibrate, and drives the slide to make the elastic brush strip clean the inner walls of the front and rear of the bed, thus facilitating the timely removal of adhering debris, improving cleaning intensity, and avoiding damage to the baffle.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0021] Example 1, as Figures 1-11 As shown, a gantry-type five-sided machining center includes a bed 1. Chip collection grooves and liquid collection chambers are respectively provided on the left side and bottom of the bed 1. A gantry frame 2 is slidably installed on the top of the bed 1. A universal machining mechanism 21 is provided on the right side of the gantry frame 2. An air jet disc 22 is provided on the universal machining mechanism 21. A mounting table 3 is fixedly connected to the bottom of the inner cavity of the bed 1. A rotating plate 31 and a torque shaft 33 are rotatably connected to the left and right sides of the mounting table 3. A baffle 34 connected to the rotating plate 31 is wound on the torque shaft 33. A U-shaped filter channel 6 is slidably engaged between the front and rear sides of the mounting table 3 and the inner wall of the bed 1. A spiral shaft 61 adapted to the filter channel 6 is rotatably connected to the inner wall of the bed 1. The inner wall of the bed 1 has a slide 8 on both the front and back sides. A spring brush strip 83 is slidably inserted on the side of the slide 8 away from the middle of the bed 1. The outer surface of the spring brush strip 83 has bristles (not shown in the figure). The slide 8 is equipped with an adjustment component that drives the spring brush strip 83 to retract. The right wall of the bed 1 is equipped with a drive component that drives the rotating plate 31 and the filter channel 6 to vibrate and the slide 8 to move up and down.

[0022] A sliding door 11 is installed on the front wall of the bed 1. A viewing window is provided on the sliding door 11. The filter channel 6 passes through the left wall of the bed 1 and connects to the chip collection groove. A drain pipe 12 is fixedly inserted into the right wall of the liquid collection chamber.

[0023] Initially, the rotating plate 31 is close to the inner wall of the bed 1 and parallel to the left and right walls of the bed 1. The baffle 34 is in a rolled-up state. The rotating plate 31 and the baffle 34 have minimal intrusion into the space above the mounting table 3 and do not affect the installation of the workpiece. After opening the sliding door 11 or using hoisting to install the workpiece in the middle of the mounting table 3, the rotating plates 31 on both sides are controlled to deflect towards the middle, pulling out the baffle 34 and causing the baffle 34 to form a triangular guide zone on the left and right sides of the mounting table 3. During subsequent processing, the gantry 2 drives the universal machining mechanism 21 to make the air jet disc 22 follow and blow on the workpiece and surrounding area, making it easier to blow all the debris into the filter channels 6 on the front and rear sides. The moving component drives the rotating plate 31 to deflect and vibrate, the rotating plate 31 pulls the baffle 34 to vibrate, and the control drive component drives the slide 8 to make the elastic brush strip 83 clean the front and rear inner walls of the bed 1, so as to facilitate the falling off of the adhering debris and improve the cleaning intensity. In addition, by controlling the drive component to drive the spiral shaft 61 to rotate, the debris in the filter channel 6 can be output to the chip collection groove in time. With the drive component driving the filter channel 6 to vibrate, the cutting fluid can be quickly filtered out into the liquid collection chamber, and the cutting fluid attached to the debris can be removed, preventing the cutting fluid from entering the chip collection groove and avoiding the filter hole blockage, thus improving the separation and collection efficiency. The cutting fluid in the liquid collection chamber can be discharged through the drain pipe 12.

[0024] In embodiment two, based on the above embodiment, the universal machining mechanism 21 includes a sliding saddle that can move back and forth along the right wall of the gantry 2, an air jet disc 22 is fixedly sleeved on the sliding saddle, and nozzles 23 with conical ports are respectively provided around the bottom of the air jet disc 22. An air pipe for an external air source is fixedly connected to the upper wall of the air jet disc 22.

[0025] The sliding saddle drives the jet disc 22 to move along the periphery of the workpiece, which can promptly blow away the debris generated during the processing of the workpiece to the front and back sides. The nozzles 23 distributed around the perimeter and with conical ports can increase the blowing range, so that the debris can be quickly collected into the filter channel 6.

[0026] In embodiment three, based on the above embodiment, a shaft block is fixedly connected to the inner wall of the bed 1 and rotatably connected to the top of the torque shaft 33, and a spiral spring is provided between the torque shaft 33 and the shaft block.

[0027] A pin 32 is fixedly connected to the bottom of the rotating plate 31. A sliding frame 4 is slidably connected to the lower wall of the inner cavity of the mounting platform 3 and is movably engaged with the pin 32. A multi-stage telescopic cylinder 41 with its telescopic end engaged with the sliding frame 4 is fixedly connected to the front wall of the inner cavity of the mounting platform 3. The rear end of the multi-stage telescopic cylinder 41 has an anti-detachment block.

[0028] The retraction of the multi-stage telescopic cylinder 41, along with the anti-detachment block, drives the sliding frame 4 forward. The sliding frame 4 presses the pin 32, causing the rotating plates 31 on both sides to deflect towards the center. The baffle 34 rolled up on the torque shaft 33 is thus pulled out. Together with the rotating plate 31, a triangular guide zone is formed on the left and right sides of the mounting platform 3, thereby optimizing the airflow direction and guiding debris to the filter channels 6 on both sides. During this process, the use of a spiral spring ensures the adaptive retraction and extension of the baffle 34 when the rotating plate 31 deflects.

[0029] In embodiment four, based on the above embodiments, the drive assembly includes an L-shaped elastic bent rod 47 that is slidably engaged with the inner wall of the right side of the mounting platform 3. The filter channel 6 is fixedly connected to the elastic bent rod 47. A pin 46 is fixedly connected to the bottom of the elastic bent rod 47 and slidably connected to the lower wall of the inner cavity of the mounting platform 3. A toothed plate 44 that passes through the slide frame 4 is slidably engaged with the lower wall of the inner cavity of the mounting platform 3. The bottom of the toothed plate 44 has a through groove that matches the pin 46, and the lower wall of the through groove has a movable engagement with the pin 46. The inclined groove 45, the upper wall of the middle part of the slide frame 4 is fixedly connected to an electromagnetic block 42, the inner wall of the middle part of the slide frame 4 is slidably engaged with an elastic magnetic wedge 43, the electromagnetic block 42 is energized to attract the elastic magnetic wedge 43, the surface of the tooth plate 44 is linearly opened with several slots that are movably engaged with the elastic magnetic wedge 43, the right wall of the bed 1 is rotatably connected to a worm gear 5, the worm gear 5 is driven by a positive and negative motor installed on the front wall of the bed 1, and the middle part of the worm gear 5 is fixedly sleeved with a cam 51 that movably abuts against the elastic bent rod 47.

[0030] When the multi-stage telescopic cylinder 41 retracts, causing the rotating plate 31 and the baffle 34 to form a triangular guide zone, the sliding frame 4 moves to the middle of the toothed plate 44, and the elastic magnetic wedge 43 engages with the new slot. The baffle 34 on the torque shaft 33 is about to be fully released. The forward and reverse motors drive the worm gear 5 to rotate forward and reverse at corresponding intervals. The worm gear 5 then drives the cam 51 to intermittently squeeze the elastic bent rod 47. When the elastic bent rod 47 is pressed to the left, the pin 46 squeezes the inclined groove 45, causing the toothed plate 44 to move forward slightly. The slot on the toothed plate 44 then squeezes the vertical surface of the elastic magnetic wedge 43, causing the sliding frame 4 to move forward slightly again, thereby causing the rotating plate 31 to deflect further and tighten the baffle 34. When the elastic bend rod 47 disengages, it drives the toothed plate 44 to automatically reset. The corresponding torque shaft 33 slightly retracts the baffle cloth 34. As the worm gear 5 continues to rotate, the rotating plate 31 and the baffle cloth 34 vibrate continuously, causing the debris adhering to them to fall off automatically. During this period, when the elastic bend rod 47 moves back and forth, it drives the filter channel 6 to vibrate synchronously, which can quickly filter the cutting fluid into the collection chamber and avoid filter hole blockage, thus improving the separation and collection efficiency. Subsequently, the control solenoid block 42 is energized to attract the elastic magnetic wedge block 43 to move upward and disengage from the slot. In conjunction with the control of the multi-stage telescopic cylinder 41, the cylinder extends and resets. The torque shaft 33 uses its own elasticity to automatically retract the baffle cloth 34 and drive the rotating plate 31 to reset.

[0031] Furthermore, the cover 34 is made of nylon canvas and its surface can be coated with PVC or polyurethane material.

[0032] This design ensures that the baffle 34 has moderate elasticity, can generate a significant vibration amplitude when suddenly tightened, and rebounds quickly. The inertial force can effectively strip away debris, and it is waterproof, oil-proof, and has a smooth surface, which can reduce the problem of debris being difficult to shake off due to the adhesion of cutting fluid.

[0033] In embodiment five, based on the above embodiments, the drive assembly further includes rollers 7 rotatably connected to the left and right walls of the bed 1. Both ends of the upper and lower rollers 7 on the front and rear sides are movably sleeved with transmission belts 71. The slide 8 is fixedly connected to the transmission belts 71. The right end of the lower roller 7 is fixedly sleeved with a worm gear 73 that meshes with the worm 5. The worm 5 has threads in opposite directions on both sides.

[0034] The worm gear 5 is driven by a forward and reverse motor to rotate forward and reverse at corresponding intervals. The worm gear 5 drives the worm gear 73 to make the roller 7 rotate forward and reverse synchronously. The transmission belt 71 drives the slide 8 to move the elastic brush strip 83 up and down to clean the front and rear inner walls of the bed 1. The forward and reverse rotation range of the worm gear 5 corresponds to the cleaning range of the elastic brush strip 83.

[0035] In Example 6, based on the above examples, the adjustment assembly includes a guide block 81 that is slidably inserted into the middle of the slide 8. The guide block 81 has a guide groove 82. The upper side of the guide groove 82 is inclined and the lower side is vertical. The inner wall of the vertical part near the inclined direction has a groove. The inner wall of the elastic brush strip 83 is fixedly connected to a T-shaped pin 84 that is movably inserted into the slide 8. The pin 84 is movably engaged with the guide groove 82. The upper and lower sides of the front and rear walls of the inner cavity of the bed 1 are fixedly connected to a stop block 13 and a stop bracket 14 corresponding to the guide block 81.

[0036] When the initial slide 8 moves to the top, the guide block 81 is pressed down by the stop block 13 and is in a downward state. The inclined part in the guide groove 82 is engaged with the pin block 84. The elastic brush strip 83 is relatively far away from the slide 8 and is in a natural extension and contraction state. When the slide 8 is driven down, the elastic brush strip 83 automatically cleans the front and rear inner walls of the bed 1 and the inner wall of the front sliding door 11. When the slide 8 moves down to the bottom, the guide block 81 is pressed by the stop block 14 and drives the guide groove 82 to move upward. The pin block 84 moves backward and is stably engaged with the groove in the vertical part of the guide groove 82. The elastic brush strip 83 is thus driven to approach the slide 8 and move away from the front and rear inner walls of the bed 1, thereby ensuring that the elastic brush strip 83 will not clean when the slide 8 moves upward.

[0037] In embodiment seven, based on the above embodiment, a transmission gear 72 is fixedly sleeved on the right side of the lower roller shaft 7, and a gear cylinder 74 that meshes with the transmission gear 72 is rotatably connected to the right wall of the bed 1. Several ratchet grooves are opened on the outer circumference of the right end of the spiral shaft 61, and an elastic ratchet pawl that is rotatably engaged with the ratchet groove is rotatably connected to the inner wall of the gear cylinder 74.

[0038] When the lower roller 7 rotates, the transmission gear 72 drives the toothed cylinder 74 to rotate synchronously. The elastic pawl can push the ratchet groove to drive the spiral shaft 61 to rotate and transport the debris in the filter channel 6 to the left. When the roller 7 rotates in the opposite direction, the spiral shaft 61 automatically stops transporting.

[0039] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
