Description

Technical Field

[0001] This utility model relates to the field of CNC sawing machines, specifically a feeding device for CNC sawing machines. Background Technology

[0002] CNC sawing machines achieve high precision, high efficiency, and high flexibility in sawing processes through digitalization and automation technologies. They are widely used in industries such as machinery manufacturing, metal processing, and woodworking. They not only improve production quality and efficiency but also reduce labor costs and material waste. They are an indispensable piece of equipment in modern manufacturing. During the use of CNC sawing machines, materials need to be transported through a feeding device to facilitate material processing.

[0003] When a CNC sawing machine is in use, if the lead screw drives the guide rail to move, and the lead screw is not lubricated in time, it will cause a lot of noise during the movement of the guide rail. In addition, when cutting wood, wood strips may be cut and stick to the surface of the lead screw. At this time, the movement of the guide rail will be blocked by the wood strips, which will cause the material feeding process to be blocked. Therefore, a feeding device for CNC sawing machines is proposed to address the above problems. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and avoid problems such as material blockage and noise during transportation, this utility model proposes a CNC sawing machine feeding device.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a CNC sawing machine feeding device, including a worktable, two lead screws are arranged on the front and rear sides of the top of the worktable, a sliding sleeve is threaded on the surface of the lead screw, a lubrication component is arranged at the bottom of the sliding sleeve, an anti-blocking component is arranged on the side of the sliding sleeve, and a feeding table is fixedly connected to the top of the sliding sleeve.

[0006] The lubrication assembly includes an oil reservoir fixedly installed at the bottom of the sliding sleeve. A drive rod is slidably connected to one end of the oil reservoir near the edge of the worktable. An arc-shaped plate is fixedly installed at the end of the drive rod away from the oil reservoir. A buffer spring is fixedly installed on the surface of the drive rod. A push rod is rotatably connected to one end of the drive rod near the inside of the oil reservoir. Spray nozzles are fixedly installed inside the left and right sides of the oil reservoir. A sliding tube is slidably connected inside the spray nozzle. A rotating plate is rotatably connected to the inner wall of the sliding tube. A fixing plate is fixedly installed on the inner wall of the sliding tube. A protrusion is fixedly installed on the inner wall of the worktable.

[0007] Preferably, the active rod passes through both the inner and outer sides of the oil reservoir, and the end of the buffer spring away from the active rod is fixedly connected to the outer wall of the oil reservoir. When the active rod slides inside the oil reservoir, the buffer spring will accumulate elastic force.

[0008] Preferably, the end of the push rod away from the drive rod is rotatably connected to the end of the sliding tube located inside the oil reservoir. The drive rod pushes the push rod to make it slide the sliding tube inside the nozzle. The nozzle extends to the outside of the oil reservoir, and the end of the nozzle away from the oil reservoir faces the bottom of the lead screw.

[0009] Preferably, there are four rotating plates distributed circumferentially inside the sliding tube. The fixed plate and the rotating plate are fitted together at the end near the inside of the oil reservoir. When the sliding tube moves away from the oil reservoir, the rotating plate will unfold and fit against the surface of the fixed plate under the resistance of the lubricating oil. When the sliding tube moves towards the oil reservoir, the rotating plate will fit against the inner wall of the sliding tube under the resistance of the lubricating oil.

[0010] Preferably, the protrusions are evenly spaced on the surface of the worktable, and the protrusions and the arc plate are adapted to contact each other. When the arc plate moves, it will periodically contact the protrusions, at which time the arc plate is pushed into the interior of the oil reservoir.

[0011] Preferably, the anti-blocking component includes a connecting rod fixedly mounted on the surface of the sliding sleeve, an air pump fixedly mounted on the other end of the connecting rod, and an air pipe fixedly mounted on the surface of the air pump.

[0012] Preferably, the air pipe faces the lead screw, the lead screw is fixedly connected to the drive end of the motor, the air pump is electrically connected to the motor, and the air pump is also driven when the motor moves. At this time, the air pipe sprays airflow onto the surface of the lead screw, causing any wood strips that may be stuck to the surface of the lead screw to be blown away.

[0013] The advantages of this utility model are:

[0014] This invention achieves periodic lubrication of the lead screw by periodically contacting the protrusion with the arc plate during the feeding process. At this time, the nozzle sprays lubricating oil onto the surface of the lead screw, so that the sliding sleeve will not be blocked or make noise when moving on the surface of the lead screw.

[0015] In addition, during the feeding process, the air pump will spray airflow onto the surface of the lead screw through the air pipe. The airflow will blow away any wood strips that may be stuck to the surface of the lead screw, preventing the sliding sleeve from contacting the wood strips and causing them to move into the interior of the sliding sleeve, thus avoiding blockage of the sliding sleeve.

[0024] 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.

[0025] The following is in conjunction with the appendix Figure 1 —6 provides further detailed information about this application.

[0026] This application discloses a feeding device for a CNC sawing machine. (Refer to...) Figure 1A CNC sawing machine feeding device includes a worktable 1, two lead screws 2 are provided on the front and rear sides of the top of the worktable 1, a sliding sleeve 3 is threadedly connected to the surface of the lead screw 2, a lubrication component 4 is provided at the bottom of the sliding sleeve 3, an anti-blocking component 5 is provided on the side of the sliding sleeve 3, and a feeding table 6 is fixedly connected to the top of the sliding sleeve 3.

[0027] Reference Figure 2 - Figure 5 The lubrication assembly 4 includes an oil reservoir 41 fixedly installed at the bottom of the sliding sleeve 3. A drive rod 42 is slidably connected to one end of the oil reservoir 41 near the edge of the worktable 1. An arc-shaped plate 43 is fixedly installed at the end of the drive rod 42 away from the oil reservoir 41. A buffer spring 44 is fixedly installed on the surface of the drive rod 42. The drive rod 42 passes through both the inner and outer sides of the oil reservoir 41. The end of the buffer spring 44 away from the drive rod 42 is fixedly connected to the outer wall of the oil reservoir 41. When the drive rod 42 slides inside the oil reservoir 41... When activated, the buffer spring 44 accumulates elastic force. A push rod 45 is rotatably connected to the end of the active rod 42 near the inside of the oil reservoir 41. Nozzles 46 are fixedly installed inside the left and right sides of the oil reservoir 41. A sliding tube 471 is slidably connected inside the nozzle 46. The end of the push rod 45 away from the active rod 42 is rotatably connected to the end of the sliding tube 471 located inside the oil reservoir 41. The active rod 42 pushes the push rod 45, causing it to push the sliding tube 471 to slide inside the nozzle 46. The nozzle 46 penetrates into the oil reservoir. Outside the reservoir 41, the end of the nozzle 46 away from the reservoir 41 faces the bottom of the lead screw 2. A rotating plate 472 is rotatably connected to the inner wall of the sliding tube 471, and a fixed plate 473 is fixedly installed on the inner wall of the sliding tube 471. There are four rotating plates 472 distributed circumferentially inside the sliding tube 471. The fixed plates 473 and the ends of the rotating plates 472 near the inside of the reservoir 41 are fitted together. When the sliding tube 471 moves away from the reservoir 41, the rotating plates 472 will be in contact with the lubricating oil. Under the action of force, it unfolds and adheres to the surface of the fixed plate 473. When the sliding tube 471 moves towards the oil reservoir 41, the rotating plate 472 will adhere to the inner wall of the sliding tube 471 under the action of lubricating oil resistance. The inner wall of the worktable 1 is fixedly installed with protrusions 48. The protrusions 48 are evenly distributed on the surface of the worktable 1. The protrusions 48 and the arc plate 43 are adapted to each other and contact each other. When the arc plate 43 moves, it will periodically contact the protrusions 48. At this time, the arc plate 43 is pushed into the interior of the oil reservoir 41.

[0028] Reference Figure 6The anti-blocking component 5 includes a connecting rod 51 fixedly installed on the surface of the sliding sleeve 3. An air pump 52 is fixedly installed at the other end of the connecting rod 51. An air pipe 53 is fixedly installed on the surface of the air pump 52, facing the lead screw 2. The lead screw 2 is fixedly connected to the drive end of the motor. The air pump 52 is electrically connected to the motor. When the motor moves, the air pump 52 will also be driven. At this time, the air pipe 53 sprays airflow onto the surface of the lead screw 2, causing any wood strips that may be stuck to the surface of the lead screw 2 to be blown away.

[0029] Working principle: The operator places the material to be processed on the top of the feeding table 6, and then the drive motor drives the lead screw 2 to rotate. At this time, the two lead screws 2 will drive the sliding sleeve 3 and the feeding table 6 to move in the left and right directions, thereby transporting the material to the processing area for processing.

[0030] During the movement of the sliding sleeve 3, the sliding sleeve 3 will drive the fixedly connected oil reservoir 41 to move accordingly. At this time, the oil reservoir 41 will drive the active rod 42 and the arc plate 43 to move. At this time, the arc plate 43 will periodically contact the protrusion 48. Therefore, under the force of the protrusion 48, the arc plate 43 will push the active rod 42 to move into the oil reservoir 41. At this time, the active rod 42 will compress the buffer spring 44. Simultaneously, the active rod 42 will push the push rod 45 to rotate, causing the push rod 45 to push the sliding tube 471 to move into the nozzle 46. Since the inside of the oil reservoir 41 is full of lubricant... When the sliding tube 471 moves, the rotating plate 472 inside it will be resisted by the lubricating oil. Therefore, the rotating plate 472 will rotate to fit against the surface of the fixed plate 473. At this time, the rotating plate 472 blocks the inside of the sliding tube 471. As the sliding tube 471 continues to move, the rotating plate 472 will push the lubricating oil inside the nozzle 46 to spray out, so that the lubricating oil is sprayed onto the surface of the lead screw 2. Then the sliding sleeve 3 continues to move on the surface of the lead screw 2, evenly coating the surface of the lead screw 2 with lubricating oil, and avoiding noise during the movement of the sliding sleeve 3.

[0031] While the motor drives the lead screw 2 to rotate, the air pump 52, which is electrically connected to the motor, is also driven. At this time, the air pump 52 will be started and airflow will be sprayed onto the surface of the lead screw 2 through the air pipe 53. The airflow will blow away any wood strips that may be stuck to the surface of the lead screw 2, thus preventing the sliding sleeve 3 from contacting the wood strips and causing blockage when it moves.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
