Description

Technical Field

[0001] This utility model belongs to the field of tool grinding technology, and in particular relates to a CNC tool grinding machine with a novel feeding mechanism. Background Technology

[0002] Tool grinders are essential auxiliary equipment in metal cutting processes, used to sharpen various metal cutting tools. Tool grinders are characterized by high precision, good rigidity, and economic practicality, and are particularly suitable for sharpening various small and medium-sized tools, such as reamers, taps, twist drills, reamers, various milling cutters, milling cutter heads, and gear shapers. With appropriate attachments, they can grind external diameters, internal diameters, and flat surfaces, and can also be used to grind templates and molds.

[0003] In the prior art, Chinese utility model patent CN215201419U discloses a feeding mechanism for a grinding machine, including a feeding housing, a discharge box fixedly connected to one side of the lower end of the feeding housing, a feed hopper at the upper end of the feeding housing, a discharge channel at the lower end of the feed hopper, a guide groove at the bottom of the discharge channel, the guide groove extending into the discharge box, and a discharge channel opened in the discharge box located above the guide groove. One end of the discharge channel is connected to the discharge channel, and the other end of the discharge channel extends to the outside of the discharge box. A plurality of evenly spaced transfer rollers are fixedly installed in the guide groove. This utility model provides a feeding mechanism with simple structure, convenient use, and improved conveying efficiency.

[0004] In existing technologies, the feeding hopper and several evenly spaced conveyor rollers can improve the conveying efficiency and prevent abrasions during material pipe conveying, but there are certain shortcomings in overall use:

[0005] First, the aforementioned existing technology continuously feeds the workpiece into the grinding area, which makes it impossible to achieve accurate grinding for each workpiece and reduces the accuracy of grinding.

[0006] Secondly, dust adheres to the surface of the workpiece during storage before feeding. This dust directly affects the stability and accuracy of the grinding process, thus reducing machining precision. During grinding, friction between the dust and the workpiece surface causes scratches or other defects, ultimately lowering the overall quality of the workpiece. Utility Model Content

[0007] To address the technical problems of continuous feeding reducing grinding accuracy and dust adhering to the workpiece surface, which directly affects the stability and accuracy of the grinding process, thereby reducing machining precision and overall quality, this invention provides a CNC tool grinder with a novel feeding mechanism.

[0008] To achieve the above objectives, this utility model provides the following technical solution: A CNC tool grinding machine with a novel feeding mechanism includes two symmetrically arranged supports, a conveying roller rotatably mounted between the two supports, a plurality of conveying plates mounted on the surface of the conveying roller, a conveying groove opened on one side of the end of each conveying plate, a vibrating plate mounted on the opposite side of every two conveying plates, the vibrating plate being wavy and one end being fixedly connected to the conveying plate, a spring being fixedly mounted on the side of the vibrating plate, and the other end of the spring being fixed to the bottom end of the vibrating plate.

[0009] The top of the bracket is equipped with a dust-collecting component for removing dust that has been shaken off the surface of the material.

[0010] By rotating the conveyor rollers and driving the conveyor plate to rotate, workpieces can be conveyed individually, avoiding congestion or jamming caused by multiple workpieces entering at the same time. This ensures the stability and accuracy of feeding, reduces labor intensity, and improves work efficiency. At the same time, the vibrating plate can vibrate the workpiece during the feeding process, shaking off the dust adhering to the surface for dust removal, which improves the subsequent processing effect.

[0011] In the aforementioned CNC tool grinder with a novel feeding mechanism, the vibrating plate is made of rubber material.

[0012] Vibration plates made of rubber are flexible and can be bent, thus working in conjunction with springs to achieve a vibration effect.

[0013] In the aforementioned CNC tool grinding machine with a novel feeding mechanism, the dust collection assembly includes a support rod fixedly installed on the top of a bracket, a mounting plate fixedly installed on the top of the support rod, and a dust collector fixedly installed on the top of the mounting plate.

[0014] The mounting plate prevents workpieces from slipping out of the gaps, and also allows for the installation of a vacuum cleaner to remove the shaken-off dust, thus protecting the surrounding working environment.

[0015] In the aforementioned CNC tool grinding machine with a novel feeding mechanism, an inclined support plate is fixedly installed on one side of the bracket for automatic material sliding down. Two sets of sliding grooves are provided on the upper surface of the support plate, and baffles are slidably installed inside the sliding grooves.

[0016] By using support plates and baffles, the workpiece can fall automatically, achieving the effect of automatic feeding. At the same time, the stop blocks limit the movement, facilitating subsequent feeding operations.

[0017] In the aforementioned CNC tool grinding machine with a novel feeding mechanism, a feeding port is provided at the lower end of the support plate, and two symmetrically arranged stop blocks are fixedly installed on the lower surface of the support plate, with the stop blocks located on both sides of the feeding port.

[0018] In the aforementioned CNC tool grinder with a novel feeding mechanism, a guide groove is fixedly installed on the other side of the support, a rotating shaft is rotatably installed inside the guide groove, and a rubber wheel is fixedly installed on the surface of the rotating shaft.

[0019] The use of rubber wheels increases the friction with the workpiece, greatly improving the feeding effect.

[0020] In the aforementioned CNC tool grinder with a novel feeding mechanism, the opposing surfaces of the rubber wheels are arranged in an arc shape.

[0021] In the aforementioned CNC tool grinding machine with a novel feeding mechanism, a receiving plate is fixedly installed on the upper surface of the guide groove near the support, and an opening is provided in the middle of the receiving plate.

[0022] In summary, compared with the prior art, the CNC tool grinding machine with a novel feeding mechanism provided by this utility model has the following beneficial effects:

[0023] 1. This utility model, through the use of conveyor rollers, conveyor plates, conveyor troughs, vibrating plates, and springs, enables single-piece feeding of workpieces, avoiding congestion or jamming caused by multiple workpieces entering simultaneously, thereby ensuring the stability and accuracy of feeding.

[0024] 2. This utility model, through the setting of support rod, dust collector and mounting plate, can remove dust from the surface of the workpiece while feeding, which greatly improves the subsequent grinding quality and protects the surrounding working environment. Attached Figure Description

Detailed Implementation

[0034] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0035] refer to Figure 1 A CNC tool grinder with a novel feeding mechanism includes a support plate 10 and a workpiece 11. The support plate 10 is inclined to facilitate the downward sliding of the workpiece 11. The surface of the support plate 10 has two sets of through-type sliding grooves 13 arranged front and back. A baffle 14 is slidably installed inside the sliding groove 13. Two symmetrically arranged stops 12 are fixedly installed on the upper surface of the lower end of the support plate 10 to limit the workpiece 11. A support leg 35 is fixedly installed on the lower surface of the support plate 10.

[0036] Specifically, the workpieces 11 are laid flat on the upper surface of the support plate 10 in sequence. The baffle 14 is slidably installed to adjust the length of the workpieces 11 according to their length, which is convenient for use with workpieces 11 of different lengths and is practical. The baffle 12 at the lower end of the support plate 10 blocks the workpieces 11 to facilitate subsequent individual feeding.

[0037] Further reference Figure 2 Two double-headed cylinders 15 are fixedly installed on the lower surface of the support plate 10. The two double-headed cylinders 15 are located between each set of slide grooves 13. The bottom end of the baffle 14 passes through the interior of the slide groove 13. The two output ends of the double-headed cylinders 15 are respectively connected to the bottom end of the baffle 14.

[0038] Specifically, the double-headed cylinder 15 pulls the baffle 14 to slide inside the slide groove 13, thereby adjusting the distance between the baffles 14, which can be adjusted according to the length of the workpiece 11, making it convenient for workpieces 11 of different lengths to use.

[0039] Further reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 Two brackets 17 are fixedly installed on one side of the lower end of the support plate 10. A conveying roller 19 is rotatably installed between the two brackets 17. A first motor 18 for driving the conveying roller 19 is fixedly installed on one side of the brackets 17. Several conveying plates 20 are fixedly installed on the surface of the conveying roller 19. An arc-shaped conveying groove 21 is opened on one side of the outer end of the conveying plate 20 for fitting the circular workpiece 11. A feeding port 16 for cooperating with the conveying plate 20 is opened on the lower surface of the support plate 10.

[0040] Specifically, when the first motor 18 drives the conveyor roller 19 to rotate, the conveyor plate 20 on the surface of the conveyor roller 19 rotates to lift the workpiece 11 from the feed port 16 and rotates to transport it to the next station. The conveyor roller 19 continues to rotate, conveying each workpiece 11 from the feed port 16. No manual feeding by operators is required, allowing for the feeding of a single workpiece 11. The single-feeding mechanism of the grinding machine ensures that only one workpiece 11 is fed at a time, avoiding congestion or jamming caused by multiple workpieces 11 entering simultaneously. This guarantees the stability and accuracy of the feeding, reduces labor intensity, and improves work efficiency.

[0041] Further reference Figure 4 and Figure 6 A vibrating plate 22 is fixedly installed on the opposite side of every two conveyor plates 20. The vibrating plate 22 is wavy and one end is fixedly connected to the conveyor plate 20. The vibrating plate 22 is made of rubber material. A spring 23 is fixedly installed on the side of the vibrating plate 22, and the other end of the spring 23 is fixed to the bottom end of the vibrating plate 22.

[0042] Specifically, when the conveyor plate 20 drives the workpiece 11 to rotate above the conveyor roller 19, it continues to rotate, causing the workpiece 11 to fall between two symmetrical vibrating plates 22. Since the bottom of the conveyor roller 33 is fixedly connected to the spring 23, the workpiece 11 vibrates continuously between the two vibrating plates 22, shaking off the dust adhering to the surface of the workpiece 11, thus improving the subsequent processing effect.

[0043] Furthermore, refer to Figure 1 and Figure 6A support rod 24 is fixedly installed on the top of the bracket 17, and a vacuum cleaner 25 is fixedly installed on the top of the support rod 24. The vacuum cleaner 25 is existing technology and will not be described in detail in this solution. The air inlet of the vacuum cleaner 25 passes through the support rod 24 and is connected to multiple vacuum heads.

[0044] Specifically, when the conveyor plate 20 transports the workpiece 11, it continues to feed when it rises directly above the conveyor roller 19. The distance between the adjacent conveyor plate 20 and the mounting plate 26 is reduced to prevent the workpiece 11 from slipping out of the gap. At the same time, the vacuum cleaner 25 sucks out the dust after the workpiece 11 shakes off the dust to prevent the dust from polluting the surrounding working environment.

[0045] Further reference Figure 1 , Figure 4 , Figure 5 and Figure 8 A column 27 is fixedly installed on one side of the conveyor roller 19. A U-shaped guide trough 28 is fixedly installed on the upper surface of the column 27. A receiving plate 29 is fixedly installed on the upper surface of the guide trough 28 near the conveyor roller 19 to receive the conveyed workpiece 11. An opening 30 is opened in the middle of the receiving plate 29 to allow material to pass through when the conveyor plate 20 is conveying, preventing interference with the rotation of the conveyor plate 20 and affecting the normal operation of the equipment. The end of the receiving plate 29 is connected to the processing station of the grinding machine. The processing station of the grinding machine is existing technology and will not be described in detail in this solution.

[0046] Further reference Figure 8 A rotating shaft 32 is rotatably installed inside the guide trough 28. A second motor 31 driving the rotating shaft 32 is fixedly installed on one side of the guide trough 28. A conveying roller 33 is fixedly installed on the surface of the second motor 31 for conveying the workpiece 11 forward. Two symmetrically arranged rubber wheels 34 are fixedly installed on the surface of the conveying roller 33. The opposite surfaces of the rubber wheels 34 are arc-shaped to protect the workpiece 11 and prevent damage to the surface of the workpiece 11 during transportation, which would affect the subsequent processing effect. At the same time, the rubber wheels 34 increase the friction between the workpiece 11 and the conveying roller 33, preventing the conveying roller 33 from slipping and spinning idly, thus improving the feeding effect.

[0047] Specifically, when the conveyor plate 20 drives the workpiece 11 to rotate, and the workpiece 11 is located on the side and below, the workpiece 11 slides down from the conveyor plate 20, enters the guide groove 28 through the receiving plate 29, and is located between the two rubber wheels 34 for forward conveying to the processing station of the grinding machine for processing.
