[0002] In drill bit manufacturing, especially in automated production lines, ensuring the drill bit enters the processing area in the correct direction is crucial for guaranteeing machining accuracy and equipment safety. Traditional methods often rely on manual visual judgment or simple mechanical stop structures, which suffer from low efficiency, susceptibility to errors, and poor adaptability. Particularly when drill bit sizes vary or batches are mixed, manual operation struggles to ensure consistency and reliability, while fixed mechanical structures cannot flexibly adapt to drill bits of different diameters, leading to inaccurate positioning or ineffective prevention of drill bits moving in the wrong direction. Summary of the Invention

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] like Figure 1 , Figure 2As shown, the auxiliary device for determining the direction of the drill bit includes a connecting seat 1 installed on the drill bit processing equipment. The connecting seat 1 is provided with at least a pair of adjustable-gap reference members 2, which are arranged opposite each other in pairs. The gap between them can be adjusted according to the diameter of the drill bit shank. One end of the connecting seat 1 is provided with a side plate 3, on which a sensor 4 for detecting whether the drill bit is in position is installed. A baffle 5 is connected above the side plate 3 via a connecting shaft to prevent the processed drill bit from re-entering. The baffle 5 can rotate around the connecting shaft under the push of the drill bit and reset under gravity or spring action, making it easy to remove the drill bit. The baffle 5 can achieve spacing adjustment through the cooperation of the adjusting rod 6 and the adjusting nut 7 to block workpieces of different sizes. The sensor 4 is connected to the external control system signal to output the drill bit direction determination result.

[0019] Each reference part 2 is provided with an inclined edge, and the two inclined edges of the two opposing reference parts 2 cooperate to form a V-shaped opening, which is used to better fit and position the cylindrical drill bit shank.

[0020] The reference component 2 is connected to the connecting seat 1 via a detachable connection structure. The reference component 2 has a sliding groove at its bottom, and the connecting seat 1 has a matching guide rail. The reference component 2 has a wedge-shaped surface, and the connection is achieved by locking with a wedge block. The reference component 2 has a groove at its bottom, and the connecting seat 1 has a matching protrusion.

[0021] Sensor 4 is a photoelectric sensor or proximity switch, with its probe facing the center of the gap between a pair of reference members 2. A counterweight is provided at the lower end of the baffle 5 to achieve its reset using gravity. A tension spring is provided between the baffle 5 and the side plate 3 to provide reset for the baffle 5.

[0022] The working principle of this auxiliary device is based on the coordinated action of mechanical positioning of the drill bit shank and detection by sensor 4. When the drill bit enters the processing area, its shank first falls into a V-shaped opening formed by a pair of adjustable reference parts 2. The spacing of the opening can be adjusted according to the drill bit diameter to ensure that the drill bit is centered.

[0023] If the direction is correct, the drill bit continues to advance until it reaches the sensor 4 sensing position. If the direction is incorrect, the drill bit cannot advance mechanically and cannot reach the sensor 4 sensing position.

[0024] If the drill bit is in the correct orientation and reaches the sensing position of sensor 4, indicating that the drill bit is in place, the drill bit orientation is determined to be correct. The automated robotic arm on the drill bit processing equipment then automatically grasps the drill bit. The baffle 5 rotates around the hinge axis under the push of the drill bit, allowing the drill bit to pass. After passing through, it automatically resets under gravity or spring force, preventing the next drill bit from entering the processing area. Sensor 4, such as a photoelectric sensor or a proximity switch, emits a signal towards the center of the gap to detect whether the drill bit is accurately positioned and transmits the signal to the external control system, thereby determining that the drill bit orientation is correct.

[0025] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.
