Description

Technical Field

[0001] This utility model relates to the field of drill bit and bar stock processing technology, specifically a drill bit and bar stock processing grinding device. Background Technology

[0002] Drill bit stock is the raw material used to manufacture drill bits. It is usually a metal bar with specific properties and specifications. It has high hardness, high wear resistance and good toughness. It can maintain a sharp cutting edge under high-speed cutting conditions and is suitable for processing various metal materials. It is one of the most commonly used materials for manufacturing drill bits.

[0003] Grinding equipment for machining high-hardness cutting drill bits typically consists of a base, grinding mechanism, fixture, and control system. The grinding mechanism is the core component, responsible for grinding the cutting drill bit. The fixture secures the drill bit, ensuring its stability and accuracy during grinding. The control system controls the movement trajectory and grinding parameters of the grinding mechanism to achieve precise grinding. This equipment is suitable for machining high-hardness cutting drill bits of different materials, specifications, and shapes, exhibiting high adaptability.

[0004] According to the published grinding device and grinding method for machining high-hardness cutting drill bits (publication number: CN119282833A), the above application uses a push rod and a brush plate to move back and forth. The brush plate brushes back and forth on the surface of the filter plate to collect the iron filings on the surface to the side, so as to avoid the accumulation of iron filings affecting the airflow of the filter plate. However, during the movement of the brush plate, the iron filings will stick to the surface of the brush bristles. The back and forth movement will cause the iron filings to stick to the surface of the filter plate again, thus still affecting the airflow of the filter plate. In order to address this problem, we propose a grinding device for machining drill bit bars. Utility Model Content

[0005] The purpose of this invention is to provide a grinding device for processing drill bit bars to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a grinding device for processing drill bit stock, comprising a machine base, an electric grinding tool disposed on the surface of the machine base, a connecting frame fixedly installed on the surface of the machine base, a clamp disposed within the connecting frame, a support frame fixedly installed on the surface of the machine base, a filter plate fixedly installed on the inner wall of the machine base, a recycling frame fixedly installed on the surface of the filter plate, a suction fan disposed within the machine base, and a control component disposed within the support frame, the control component comprising:

[0007] Brush bristles, which are used to clean the surface of the filter plate;

[0008] A support plate, the surface of which is in contact with the surface of the hammer block;

[0009] The striking element is used to remove adhering substances from the surface of the brush bristles, thereby cleaning the brush bristles and preventing the airflow of the filter plate from being affected by the sticky iron filings.

[0010] Preferably, the brush bristles are fixedly installed on the surface of the support plate, and the surface of the support plate is in contact with the surface of the hammer block. When the support plate moves, the brush bristles can clean the surface of the filter plate.

[0011] Preferably, the striking element includes a flat plate, which is fixedly mounted on the surface of the striking block. The flat plate is penetrated by a fixing rod and slidably connected to the fixing rod. The fixing rod is fixedly mounted on the inner wall of the slider. The setting of the fixing rod can ensure the stability of the flat plate during movement.

[0012] Preferably, the slider is penetrated by the plate and slidably connected to the plate. The surface of the plate is fixedly connected to one end of the spring, and the other end of the spring is fixedly installed on the inner wall of the slider. When the plate is no longer under force, it can bounce up under the support of the spring.

[0013] Preferably, a vertical rod is fixedly installed on the surface of the plate, the vertical rod passes through the slider and is slidably connected to the slider, and when the vertical rod is abutted, it can move longitudinally within the slider.

[0014] Preferably, the slider is penetrated by a flat rod and slidably connected to the flat rod. The flat rod is fixedly installed on the inner wall of the support frame. The surface of the support frame is fixedly installed with protrusions. When the slider is subjected to force, it can move laterally along the surface of the flat rod.

[0015] Preferably, a motor is fixedly mounted on the surface of the support frame, the output shaft of the motor is fixedly connected to the surface of the reciprocating lead screw, the reciprocating lead screw passes through the support frame and is rotatably connected to the support frame, the reciprocating lead screw passes through the slider and is threadedly connected to the slider, and the output shaft of the motor can drive the reciprocating lead screw to perform circular motion within the support frame.

[0016] Compared with the prior art, the present invention provides a grinding device for machining drill bit bars, which has the following beneficial effects:

[0017] 1. This drill bit grinding device, equipped with a control component, allows the slider to slide along the support plate under the action of the reciprocating screw. When the protrusion contacts the cut surface of the vertical rod, the vertical rod will slide within the slider under force. As the vertical rod moves, the plate fixed to the surface of the vertical rod can drive the striking block to move longitudinally in sync. During the longitudinal movement, the surface of the support plate is struck. When the brush bristles at the bottom of the support plate are subjected to the vibration force, the iron filings adhering to the surface of the brush bristles can be dislodged, thereby achieving the purpose of cleaning the brush bristles and preventing the airflow of the filter plate from being affected by the sticky iron filings.

[0018] 2. The drill bit grinding device is equipped with a striking element. When the output shaft of the motor drives the reciprocating lead screw to rotate in the support frame, the slider can be forced to move the support plate laterally along the surface of the flat rod. During the lateral movement of the support plate, the filter plate can be cleaned by the brush bristles at the bottom and pushed into the recycling frame for centralized collection.

[0024] like Figures 1-4 As shown, this utility model provides a technical solution: a grinding device for processing drill bit stock, including a machine base 1, an electric grinding cutter 2 disposed on the surface of the machine base 1, a connecting frame 3 fixedly installed on the surface of the machine base 1, a clamp 4 disposed inside the connecting frame 3, a support frame 5 fixedly installed on the surface of the machine base 1, a filter plate 6 fixedly installed on the inner wall of the machine base 1, a recycling frame 7 fixedly installed on the surface of the filter plate 6, a suction fan 8 disposed inside the machine base 1, and a control component 9 disposed inside the support frame 5, the control component 9 including... The components include brush bristles 91, support plate 92, striking block 93, and striking element 94. When the vertical rod 944 moves, the plate 941 fixed to the surface of the vertical rod 944 can drive the striking block 93 to move longitudinally in sync. During the longitudinal movement, the plate 941 strikes the surface of the support plate 92. When the brush bristles 91 at the bottom of the support plate 92 are subjected to the force of vibration, the iron filings adhering to the surface of the brush bristles 91 can be dislodged, thereby achieving the purpose of cleaning the brush bristles 91 and preventing the airflow of the filter plate 6 from being affected by the sticky iron filings.

[0025] Brush bristles 91 are fixedly installed on the surface of support plate 92, and the surface of support plate 92 is in contact with the surface of tapping block 93. When support plate 92 moves, brush bristles 91 can clean the surface of filter plate 6. Tapping element 94 includes plate 941, which is fixedly installed on the surface of tapping block 93. Plate 941 is penetrated by fixing rod 942 and slidably connected to fixing rod 942. Fixing rod 942 is fixedly installed on the inner wall of slider 945. The setting of fixing rod 942 can ensure the stability of plate 941 during movement. Slider 945 is penetrated by plate 941 and slidably connected to plate 941. The surface of plate 941 is fixedly connected to one end of spring 943. The other end of spring 943 is fixedly installed on the inner wall of slider 945. When plate 941 is no longer under force, it can bounce up under the support of spring 943. A vertical rod 944 is fixedly mounted on the surface of the flat plate 941. The vertical rod 944 passes through the slider 945 and is slidably connected to the slider 945. When the vertical rod 944 is pressed, it can move longitudinally within the slider 945. The slider 945 is passed through and slidably connected to the horizontal rod 946. The horizontal rod 946 is fixedly mounted on the inner wall of the support frame 5. A protrusion 949 is fixedly mounted on the surface of the support frame 5. When the slider 945 is subjected to force, it can move laterally along the surface of the horizontal rod 946. A motor 948 is fixedly mounted on the surface of the support frame 5. The output shaft of the motor 948 is fixedly connected to the surface of the reciprocating lead screw 947. The reciprocating lead screw 947 passes through the support frame 5 and is rotatably connected to the support frame 5. The reciprocating lead screw 947 passes through the slider 945 and is threadedly connected to the slider 945. The output shaft of the motor 948 can drive the reciprocating lead screw 947 to perform circular motion within the support frame 5.

[0026] In this invention, the drill bit to be processed is placed into the clamp 4, and the position of the clamp 4 is adjusted to fix the drill bit. After fixing, the electric grinding cutter 2 is started to run at high speed to grind the front end of the drill bit. During the grinding process, the generated iron filings are affected by the airflow of the suction fan 8 and adsorbed onto the surface of the filter plate 6. When the airflow of the filter plate 6 is slow, the motor 948 on the surface of the support frame 5 is started. The output shaft of the motor 948 drives the reciprocating screw 947 to perform circular motion within the support frame 5. During the rotation of the reciprocating screw 947, the slider 945 is subjected to force and drives the support plate 92 to move laterally along the surface of the flat rod 946. During the lateral movement, the filter plate 6 can be cleaned by the brush bristles 91 at the bottom and pushed into the collection frame 7 for centralized collection. During the movement, when the protrusion 949 abuts against the cut surface of the vertical rod 944, the vertical rod 944 will slide within the slider 945 under force. When the vertical rod 944 moves, the flat plate 941 fixed on the surface of the vertical rod 944 can drive the knocking block 93 to move longitudinally in sync. During the longitudinal movement, the surface of the support plate 92 is knocked. When the brush bristles 91 at the bottom of the support plate 92 are subjected to the vibration force, the iron filings adhering to the surface of the brush bristles 91 can be dislodged, thereby achieving the purpose of cleaning the brush bristles 91 and preventing the airflow of the filter plate 6 from being affected by the sticky iron filings.

[0027] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
