Description

Technical Field

[0001] The utility model relates to the technical field of grinding devices, in particular to a drill bit grinding device. Background Art

[0002] Chinese Patent: A Drill Bit Grinding Device and an Operation Method, Patent Authorization Number: CN 116572089A, Patent Authorization Date: August 11, 2023. In this invention, the rack frame has a first rack and a second rack. The first rack is responsible for feeding, and the first gear and the first lead screw are connected through a one-way bearing. When the first rack moves to the left, it feeds, and when the first rack moves to the right, it does not feed. The first lead screw and the first nut are thread-connected and have a self-locking function. The second rack is responsible for rotating the drill bit during grinding, and feeding and grinding are carried out separately, ensuring the grinding effect. The angle between the symmetry plane of the second dovetail groove and the grinding wheel is equal to half of the drill bit angle. The symmetry plane of the second dovetail groove is aligned with the middle of the grinding wheel, ensuring that the angle between the drill bit of different lengths and the grinding wheel is always half of the drill bit angle, ensuring the straightness of the cutting edge. However, before grinding the groove of the drill bit, manual positioning is required for this device, and the positioning accuracy is inaccurate, and the labor cost and material cost are relatively high. Therefore, a drill bit grinding device is needed to solve the above problems. Content of the Utility Model

[0003] To solve the above problems, the utility model provides a drill bit grinding device, which includes a grinding mechanism and a transmission mechanism arranged below the grinding mechanism. The grinding mechanism includes a grinding head assembly and a grinding wheel assembly installed on the grinding head assembly. The transmission mechanism includes a rotating device and a propulsion device. The rotating device and the propulsion device are connected through a first gear main shaft. A second gear main shaft is connected to the propulsion device, and a taper drill sleeve is installed inside the second gear main shaft. A guide sleeve seat is installed below the grinding wheel assembly, and a guide sleeve is arranged on the guide sleeve seat. The drill bit to be processed is placed inside the guide sleeve. The taper drill sleeve is used to fix one side of the drill bit for grinding processing. A sensor device is arranged on one side of the first gear main shaft, and the sensor device is electrically connected to a holding brake servo motor and a motor device installed on the grinding wheel assembly.

[0004] A further improvement of the utility model lies in that: the guide sleeve includes a panel with a drill bit through hole and two collar structures for limiting positions. Setting the two collar structures can limit the processing path of the drill bit and achieve a stable effect.

[0005] A further improvement of the utility model lies in that: the two collar structures are arranged in parallel with each other and are both perpendicular to the horizontal plane.

[0006] A further improvement of the present utility model lies in that: a blanking box is installed below the first gear main shaft, a sensor device is installed on the blanking box, and a pushing plate is provided on the blanking box.

[0007] A further improvement of the present utility model lies in that: the sensor device includes a sensor seat, a sensor installed on the sensor seat, a first detection oil cylinder and a second detection oil cylinder provided on one side of the sensor. The second detection oil cylinder is installed on a detection oil cylinder seat, a detection swing arm is installed on the detection oil cylinder seat, and an extension arm is installed on the detection swing arm, which can sense the drill bit, so as to realize the rapid judgment of the processing position by the sensor.

[0008] A further improvement of the present utility model lies in that: the grinding wheel assembly includes a grinding wheel body, a grinding wheel outer clamping piece provided on one side of the grinding wheel body, and a grinding wheel inner clamping piece provided on the other side.

[0009] The beneficial effects of the present utility model:

[0010] The setting of the present utility model can ensure that the grinding wheel body falls into the groove of the drill bit to be processed, reducing the processing load of the grinding wheel body; a sensor is installed on one side of the grinding wheel assembly, which can monitor the height difference of the groove type of the drill bit to be processed. After the sensor detects the height difference, it will transmit an electrical signal to the servo motor, which can control the advancing path of the motor, so as to cooperate with the adjustment of the processing height and the advancing process of the drill bit to be processed. The grinding wheel can precisely grind to the required groove depth of the drill bit to be processed, which can improve the processing efficiency, save labor costs and improve the processing accuracy while improving the processing efficiency.
