Description

Technical Field

[0001] This utility model relates to the field of CNC grinding machine technology, specifically to an automatic feeding structure for a CNC grinding machine. Background Technology

[0002] CNC grinding machines are machine tools that use grinding wheels to grind the surface of workpieces. They are widely used in modern manufacturing. In the grinding process, the efficiency and accuracy of the feeding process have a significant impact on the overall processing efficiency.

[0003] However, common automatic feeding equipment lacks a precise control mechanism during material conveying, often resulting in congestion and accumulation of materials on the conveyor belt. This not only seriously affects the feeding rhythm but may also cause material collision damage. This disorderly conveying causes more obvious damage, especially for some irregularly shaped and brittle workpieces.

[0004] To address this issue, we designed an automatic feeding and pushing structure for a CNC grinding machine. Utility Model Content

[0005] The purpose of this invention is to provide an automatic feeding structure for a CNC grinding machine to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides an automatic feeding structure for a CNC grinding machine, including a machine body. Two baffles are fixedly connected to the top two sides of the machine body. A conveyor belt is arranged between the two baffles. One of the conveyor belts has a groove, and a horizontal plate is fixedly connected to the bottom of the groove. A discharge assembly is arranged on the upper surface of the horizontal plate. The discharge assembly includes a positioning column and a rotating disk. The positioning column is fixedly connected to the horizontal plate, and the rotating disk is rotatably connected to the top of the positioning column. A lever is inserted into the side wall of the rotating disk and rotatably connected to the surface of the conveyor belt. A limit plate is rotatably connected to the middle of the side wall of the positioning column.

[0007] Furthermore, the number of the dial plates is four, and the four dial plates are respectively fixedly connected to the four edges of the dial plate.

[0008] Furthermore, the central part of the positioning column has a cavity, and an electric telescopic rod is placed inside the cavity. The bottom fixed end of the electric telescopic rod is fixedly connected to the limiting plate, and the top driving end of the electric telescopic rod is fixedly connected to the rotating plate.

[0009] Furthermore, a ball bearing is rotatably connected to the inner bottom wall of the cavity, and the other end of the ball bearing is rolledly connected to the bottom end of the electric telescopic rod.

[0010] Furthermore, a fixing block is fixedly connected to the horizontal plate, a rotating shaft is rotatably connected to the top of the fixing block, a stop block is fixedly connected to the side wall of the rotating shaft, a motor is fixedly connected inside the fixing block, and the drive end of the motor is fixedly connected to the rotating shaft.

[0011] Furthermore, a fixed shaft is fixedly provided at the top of the horizontal plate, and a retaining strip is rotatably connected to the top of the fixed shaft. A protrusion is fixedly connected to the side of the retaining strip near the rotating shaft, and the abutment and the protrusion abut against each other.

[0012] Furthermore, the side wall of the limiting plate is provided with four evenly distributed limiting openings, and the end of the card strip away from the fixed axis is provided with an inclined block that matches the limiting opening.

[0013] Furthermore, a central shaft is fixedly connected to the top center of the rotating shaft, a sleeve is fitted on the central shaft, a return spring is fixedly connected to one side of the sleeve, and the other end of the return spring is fixed to the retaining bar.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, the material feeding assembly features a deflector and a rotary disc that rotate under the push of the material, ensuring that the material is transmitted forward sequentially. This avoids disorderly accumulation and congestion of material on the conveyor belt, significantly reducing feeding time and improving the overall production efficiency of the CNC grinding machine. Simultaneously, the intermittent feeding system, through the coordinated operation of the motor, rotating shaft, abutment, clamping strip, and return spring, enables the rotary disc and deflector to intermittently guide the material, precisely controlling the feeding rhythm and further optimizing the feeding process, thus improving feeding efficiency.

[0022] 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.

[0023] Please see Figure 1 and Figure 2 This utility model provides a technical solution: an automatic feeding structure for a CNC grinding machine, including a machine body 1. Baffles 2 are fixedly connected to both sides of the top of the machine body 1. A conveyor belt 3 is arranged between the two baffles 2. A groove is opened on one of the conveyor belts 3. A horizontal plate 4 is fixedly connected to the bottom of the groove. A discharge assembly is arranged on the upper surface of the horizontal plate 4. The discharge assembly includes a positioning post 5 and a rotating disk 6. The positioning post 5 is fixedly connected to the horizontal plate 4. The top of the positioning post 5 is rotatably connected to the rotating disk 6. A lever 7 is inserted into the side wall of the rotating disk 6. The lever 7 is rotatably connected to the surface of the conveyor belt 3. A limit disk 9 is rotatably connected to the middle of the side wall of the positioning post 5. There are four levers 7, and the four levers 7 are respectively fixedly connected to the four edges of the lever 7.

[0024] In practice, once the material is placed on the conveyor belt 3, its forward movement pushes the deflector plate 7. Since the deflector plate 7 is fixed to the side wall of the rotating disk 6, the pushing force of the material causes the rotating disk 6 to rotate around the top of the positioning column 5. In this way, the material can continue to move forward while pushing the deflector plate 7 and the rotating disk 6, thus effectively preventing the material from being randomly fed onto the conveyor belt 3 under disorderly conveying conditions, and achieving orderly and quantitative control of material conveying.

[0025] See Figure 3 The center of the positioning column 5 has a cavity, and an electric telescopic rod 8 is placed inside the cavity. The bottom fixed end of the electric telescopic rod 8 is fixedly connected to the limiting plate 9, and the top driving end of the electric telescopic rod 8 is fixedly connected to the rotating plate 6.

[0026] In practice, when it is necessary to adjust the height of the lever 7, the electric telescopic rod 8 is activated, which extends or shortens to drive the rotating disk 6 to rise or fall, thereby adjusting the height position of the lever 7.

[0027] See Figure 3 The inner bottom wall of the cavity is rotatably connected to a ball bearing, and the other end of the ball bearing is rotatably connected to the bottom end of the electric telescopic rod 8.

[0028] In practice, when the rotating disk 6 rotates, the electric telescopic rod 8 will rotate in the cavity of the positioning column 5, which also causes the limiting disk 9 connected to the bottom of the electric telescopic rod 8 to rotate together. The ball bearings allow the electric telescopic rod 8 to rotate more smoothly.

[0029] See Figure 4 A fixing block 11 is fixedly connected to the horizontal plate 4. A rotating shaft 12 is rotatably connected to the top of the fixing block 11. A stop block 14 is fixedly connected to the side wall of the rotating shaft 12. A motor is fixedly connected inside the fixing block 11. The drive end of the motor is fixedly connected to the rotating shaft 12. A fixing shaft 15 is fixedly installed at the top of the horizontal plate 4. A locking strip 16 is rotatably connected to the top of the fixing shaft 15. A protrusion 17 is fixedly connected to the side of the locking strip 16 near the rotating shaft 12. The stop block 14 and the protrusion 17 abut against each other. Four evenly distributed limiting holes 10 are opened on the side wall of the limiting plate 9. An inclined block that matches the limiting hole 10 is provided at the end of the locking strip 16 away from the fixing shaft 15.

[0030] In practice, to achieve intermittent material feeding from the guide plate 7, the motor inside the fixed block 11 can be activated. The motor drives the rotating shaft 12 to rotate. When the motor drives the rotating shaft 12 to rotate, the abutment 14 on the rotating shaft 12 will contact the protrusion 17. The force generated during the contact will drive the locking strip 16 to move, causing the inclined block on the locking strip 16 to disengage from the limiting opening 10 on the side wall of the limiting disk 9. At this time, the limiting disk 9 and the rotating disk 6 connected to it are no longer restricted by the locking strip 16, thus enabling rotation.

[0031] See Figure 5 A central shaft is fixedly connected to the top center of the rotating shaft 12. A sleeve 13 is sleeved on the central shaft. A return spring 18 is fixedly connected to one side of the sleeve 13. The other end of the return spring 18 is fixedly connected to the retaining strip 16.

[0032] In practice, when the rotating shaft 12 continues to rotate and the abutment 14 rotates to the point where it no longer contacts the protrusion 17, the return spring 18 pulls the retaining strip 16 back to its original position, causing the retaining strip 16 to re-fix the limiting disc 9. In this way, the rotating disc 6 and the guide plate 7 intermittently guide the material, making the control of the material feeding process more orderly and effectively improving the accuracy and stability of the automatic feeding process of the CNC grinding machine.

[0033] Working principle: First, when the material is placed on the conveyor belt 3, the forward movement of the material will push the deflector plate 7. Since the deflector plate 7 is fixed to the side wall of the rotating disk 6, the material can continue to be transmitted forward while pushing the deflector plate 7 and the rotating disk 6 to rotate. This effectively prevents the material from being randomly fed on the conveyor belt 3 under disorderly transmission, and realizes orderly quantitative control of material transmission.

[0034] Considering the potential height differences among various materials, an electric telescopic rod 8 is incorporated into the structure to better adapt the lever 7 to different materials. When the height of the lever 7 needs adjustment, the electric telescopic rod 8 is activated, extending or shortening to raise or lower the rotating disk 6, thereby adjusting the height position of the lever 7. Simultaneously, as the rotating disk 6 rotates, the electric telescopic rod 8 rotates within the cavity of the positioning post 5, causing the limiting disk 9 connected to the bottom of the electric telescopic rod 8 to rotate as well.

[0035] To achieve intermittent material feeding between the rotary disk 6 and the guide plate 7, the motor can be started. The motor drives the rotary shaft 12 to rotate, and the abutment 14 on the rotary shaft 12 will contact the protrusion 17. The force generated during contact will drive the clamping strip 16 to move, causing the inclined block on the clamping strip 16 to disengage from the limiting opening 10 on the side wall of the limiting disk 9. At this time, the limiting disk 9 and the rotary disk 6 connected to it are no longer restricted by the clamping strip 16, thus enabling rotation. When the rotary shaft 12 continues to rotate, and the abutment 14 rotates to the point where it no longer contacts the protrusion 17, the return spring 18 will cause the clamping strip 16 to re-fix the limiting disk 9. In this way, intermittent material feeding between the rotary disk 6 and the guide plate 7 is achieved, making the control of the material feeding process more orderly and effectively improving the accuracy and stability of the automatic feeding of the CNC grinding machine.
