Abstract
Description
Technical Field
[0001] This utility model relates to the field of machining center technology, specifically to an L-shaped chip removal structure for a vertical machining center. Background Technology
[0002] A vertical machining center is an automated machine tool equipped with a program control system. This control system can logically process programs with control codes or other symbolic instructions, decode them, represent them with coded numbers, and input them into the CNC device through an information carrier to control the operation of the machine tool. Vertical machining centers effectively solve the problem of machining complex, precise, small-batch, and multi-variety parts. They are flexible, high-efficiency automated machine tools, representing the development direction of modern machine tool control technology. They are a typical mechatronics product. The waste chips generated during the production process of vertical machining centers often need to be transported and disposed of using chip conveyors.
[0003] Patent document CN210938346U discloses a chip conveyor for CNC machine tools. Its structure includes a protective cover, controller, chip discharge port, auxiliary frame, support legs, cleaning device, belt, drive wheel, traction plate, auxiliary wheel, and driven wheel. By setting a cleaning device at the bottom of the chip conveyor body, the housing is fixed to the chip conveyor body by the left and right fixing parts. Then, pressing the controller starts the micro motor, which drives the turntable to rotate through the output shaft. The turntable slides along the inner groove of the limit plate through the inner diameter protrusion, causing the rocker arm to drive the top rod to swing back and forth. The left side of the top rod is connected to the cover plate through the mounting groove, which facilitates the brush to brush back and forth along the surface of the conveyor belt, causing the scraped waste chips on the surface of the conveyor belt to fall into the drawer for temporary storage. After the waste chips of the conveyor are conveyed, the equipment is turned off and the drawer is pulled outward to deal with the waste chips inside in time, so as to achieve timely treatment of waste chips adhering to the surface of the conveyor belt.
[0004] However, due to the various shapes of the waste chips discharged during the machining process, they are relatively loose. The large accumulation space of loose waste chips makes them prone to blockage when transported inside the chip conveyor, affecting the normal use of the chip conveyor and reducing the chip removal effect. Therefore, an L-shaped chip conveying structure for vertical machining centers is proposed to solve the problems mentioned above. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides an L-shaped chip removal structure for vertical machining centers, which has advantages such as easy chip cutting. It solves the problem that the chips discharged during machine tool processing are of various shapes and are relatively loose. The loose chips have a large accumulation space, which makes them easy to cause blockages when transported inside the chip conveyor, affecting the normal use of the chip conveyor and reducing the chip removal effect.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an L-shaped chip conveyor structure for a vertical machining center, comprising a chip conveyor body, a conveyor belt inside the chip conveyor body, and a cutting mechanism and a pushing mechanism respectively arranged on the outer side of the conveyor belt; The cutting mechanism includes a protective box located on the upper side of the conveyor belt. A drive motor is fixedly installed on the top of the protective box. The output shaft of the drive motor is connected to a drive shaft located inside the protective box. One end of the drive shaft is fixedly connected to a mounting shaft. Multiple cutting wheels are fixedly installed on the outer wall of the mounting shaft. The pushing mechanism includes a pushing plate disposed above the surface of the conveyor belt and a hydraulic rod fixedly installed on the outer wall of the chip conveyor body. A counterweight is fixedly installed on the output shaft of the hydraulic rod, and a vertical rod is fixedly connected to the outside of the counterweight. A connecting frame fixedly connected to one side of the pushing plate is fixedly installed at the upper end of the vertical rod.
[0007] Furthermore, a conveyor motor connected to the conveyor belt is fixedly installed on the outer side of the chip conveyor body, and a guide frame is fixedly installed at the material receiving port of the chip conveyor body.
[0008] Furthermore, the protective box is fixedly installed on the outside of the chip conveyor body, and the side of the protective box near the material receiving port of the chip conveyor body is open and corresponds to the pusher plate.
[0009] Furthermore, a main gear is fixedly mounted on the output shaft of the drive motor, and a driven gear that meshes with the main gear is fixedly mounted on the outer wall of the transmission shaft.
[0010] Furthermore, the ends of the drive shaft and the mounting shaft that are far apart from each other are connected to the inner wall of the protective box via bearings, and the cutting wheel is located above the surface of the conveyor belt.
[0011] Furthermore, a guide plate is fixedly connected to the side of the protective box near the pusher plate.
[0012] Furthermore, a fixing plate is fixedly installed on the outer side of the chip conveyor body, a guide rail is fixedly installed on the outer wall of the fixing plate, and a slider that slides with the guide rail is fixedly installed at the bottom of the counterweight seat.
[0013] Compared with the prior art, this utility model provides an L-shaped chip removal structure for a vertical machining center, which has the following advantages: This vertical machining center uses an L-shaped chip conveyor structure. A hydraulic rod moves the counterweight, which in turn moves the vertical rod and connecting frame, simultaneously moving the pusher plate. With the assistance of the pusher plate, the loosely accumulated chips are stably pushed into the protective housing. The drive motor then rotates the main and driven gears, which in turn rotate the transmission shaft, which in turn rotates the mounting shaft, thereby rotating the cutting wheel. The cutting wheel cuts the loosely accumulated chips into small fragments, preventing them from clogging the inside of the chip conveyor during transport. This ensures stable chip removal and solves the problem that the chips produced during machining are of various shapes and are relatively loose, leading to large accumulation spaces and potential blockages during transport, thus affecting the normal operation of the chip conveyor and reducing its efficiency.

Detailed Implementation
[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figures 1 to 4 The L-shaped chip conveying structure for a vertical machining center in this embodiment includes a chip conveyor body 1, a conveyor belt 3 is provided inside the chip conveyor body 1, a conveyor motor 2 that is connected to the conveyor belt 3 is fixedly installed on the outside of the chip conveyor body 1, and a cutting mechanism and a pushing mechanism are respectively provided on the outside of the conveyor belt 3.
[0018] In this embodiment, the cutting mechanism includes a protective box 5 located on the upper side of the conveyor belt 3. The protective box 5 is fixedly installed on the outside of the chip conveyor body 1. A drive motor 6 is fixedly installed on the top of the protective box 5. The output shaft of the drive motor 6 is connected to a drive shaft 9 located inside the protective box 5. One end of the drive shaft 9 is fixedly connected to a mounting shaft 10. Multiple cutting wheels 11 are fixedly installed on the outer wall of the mounting shaft 10. The cutting wheels 11 are located above the surface of the conveyor belt 3. A main gear 7 is fixedly mounted on the output shaft of the drive motor 6, and a driven gear 8 that meshes with the main gear 7 is fixedly mounted on the outer wall of the transmission shaft 9. The ends of the transmission shaft 9 and the mounting shaft 10 that are far apart from each other are connected to the inner wall of the protective box 5 through bearings. The drive motor 6 can drive the transmission shaft 9 to rotate through the cooperation of the main gear 7 and the driven gear 8, and drive the mounting shaft 10 to rotate, thereby driving the cutting wheel 11 to rotate. The cutting wheel 11 is used to cut the accumulated loose waste chips into small pieces, so as to avoid the accumulated loose waste chips from clogging the inside of the chip conveyor body 1 during the conveying process, thus ensuring the stable chip discharge of the chip conveyor body 1.
[0019] In this embodiment, the pushing mechanism includes a pushing plate 13 disposed above the surface of the conveyor belt 3 and a hydraulic rod 14 fixedly installed on the outer wall of the chip conveyor body 1. A counterweight 15 is fixedly installed on the output shaft of the hydraulic rod 14. A vertical rod 16 is fixedly connected to the outer side of the counterweight 15. A connecting frame 17 fixedly connected to one side of the pushing plate 13 is fixedly installed at the upper end of the vertical rod 16. A fixing plate 18 is fixedly installed on the outer side of the chip conveyor body 1. A guide rail 19 is fixedly installed on the outer wall of the fixing plate 18. A slider 20 that slides with the guide rail 19 is fixedly installed at the bottom of the counterweight 15. When the counterweight 15 moves, it can drive the slider 20 to slide along the outer side of the guide rail 19, and the movement is stable.
[0020] Due to the obstruction of the cutting wheel 11 inside the protective box 5, the conveying of loose waste in the docking port of the conveyor belt 3 may be affected. Driven by the hydraulic rod 14, the counterweight 15 can be moved, and the pusher plate 13 can be moved through the vertical rod 16 and the connecting frame 17. With the assistance of the pusher plate 13, the accumulated loose waste can be stably pushed into the protective box 5. Then the cutting wheel 11 cuts the accumulated loose waste into small pieces, ensuring stable conveying.
[0021] The chip conveyor body 1 is equipped with a guide frame 4 at the receiving port. The waste chips generated by the machining center can fall into the conveyor belt 3 inside the receiving port of the chip conveyor body 1 through the guide frame 4. The protective box 5 is open on the side near the receiving port of the chip conveyor body 1 and corresponds to the pusher plate 13. At the same time, the protective box 5 is fixedly connected to the side near the pusher plate 13. When the pusher plate 13 moves towards the protective box 5, the guide plate 12 can easily guide the waste chips into the inside of the protective box 5.
[0022] The working principle of the above embodiments is as follows: During operation, the chips generated during machining at the machining center fall through the guide frame 4 onto the conveyor belt 3 inside the receiving port of the chip conveyor body 1. Due to the various shapes of the chips, they are relatively loosely piled up. By activating the hydraulic rod 14, the counterweight 15 is moved, which in turn moves the vertical rod 16 and the connecting frame 17, and simultaneously moves the pusher plate 13. With the assistance of the pusher plate 13, the loosely piled chips are stably pushed into the protective box 5. By activating the drive motor 6, the main gear 7 and the driven gear 8 are driven to rotate. Through the cooperation of the main gear 7 and the driven gear 8, the transmission shaft 9 is rotated, which in turn rotates the mounting shaft 10, thereby rotating the cutting wheel 11. The cutting wheel 11 cuts the loosely piled chips into small pieces, preventing the loosely piled chips from clogging the inside of the chip conveyor body 1 during the conveying process, thus ensuring the stable chip removal of the chip conveyor body 1.
[0023] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
