Description

Technical Field

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

[0002] A drill bit is a rotary cutting tool. Grinding is a crucial step in the drill bit manufacturing process. Grinding can significantly reduce the roughness of the drill bit surface, improve its smoothness and flatness, and thus enhance the drill bit's cutting performance.

[0003] A Chinese patent with publication number CN218800987U discloses a grinding device for drill bit processing, including a support platform on which a grinding wheel driven by a motor is mounted; an angle-adjustable support plate is mounted on the support platform on one side of the grinding wheel, and a mounting seat is hinged to the support plate. A through-type rotating cylinder is rotatably mounted inside the mounting seat, and a locking bolt is provided on the side plate of the rotating cylinder. This utility model can flexibly adjust the position of the drill bit according to the actual situation, meet the grinding needs of drill bits in various states, and ensure grinding quality.

[0004] The aforementioned grinding device for drill bit processing lacks a scalar mechanism, making it impossible to accurately control the length of the drill bit after grinding. This can easily lead to over-grinding or under-grinding, failing to meet the precision requirements for drill bit length during processing. Therefore, a new grinding device for drill bit processing is proposed to address these issues. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background, this utility model proposes a grinding device for drill bit processing.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A grinding device for drill bit processing, comprising a base, a fixed column fixedly connected to the base, mounting plates fixedly connected to both sides of the fixed column, motors mounted on the outer walls of the two mounting plates, grinding wheels mounted at the output ends of the two motors, a T-shaped groove provided on the base, a T-shaped sliding plate slidably fitted within the T-shaped groove, a movable plate fixedly connected to the top side of the T-shaped sliding plate, two triangular limiting blocks fixedly connected to the top side of the movable plate, two rod holes provided on the movable plate, movable rods inserted into the two rod holes, pressing plates fixedly connected to the top ends of the two movable rods, two first springs fixedly connected between the pressing plates and the movable plate, and the two first springs correspondingly sleeved on the movable rods. Each end of the drill bit is fixed with a rod cap. When grinding the drill bit, first place the drill bit to be ground in the placement groove formed by the two triangular limiting blocks. Then press down on the pressing plate to press and limit the drill bit, ensuring that the drill bit is stable in position during grinding and avoiding shaking or deviation, thus providing a foundation for precise grinding. After the drill bit is pressed and limited, the T-slot and T-slide plate provide good guidance for the drill bit to move towards the grinding wheel, ensuring that the drill bit moves in a straight line and that its end accurately contacts the grinding wheel. When the end of the drill bit moves to contact the grinding wheel, the motor is started, causing the grinding wheel to rotate, thereby grinding the end of the drill bit. Through stable limiting and precise guidance, combined with the high-speed rotation of the grinding wheel, precise grinding of the drill bit end can be achieved, effectively ensuring the grinding quality.

[0007] Preferably, the base has a scale mark installed on its top side, and the scale mark is located next to the T-slot. When adjusting the position of the scale rod to determine the drill bit grinding length, the scale mark provides the operator with an intuitive and accurate reference, which can quickly and accurately move the scale rod to the required position and ensure that the drill bit grinding length meets the preset requirements.

[0008] Preferably, a vertical plate is fixedly connected to the base, and a sliding groove is formed on the vertical plate. A sliding block is slidably assembled in the sliding groove. A movable frame is fixedly connected to the top side of the sliding block, and the movable frame is slidably assembled on the top side of the vertical plate. A screw hole is formed on the movable frame, and a locking bolt is rotatably assembled in the screw hole. The bottom end of the locking bolt contacts the top side wall of the vertical plate. A rod hole is formed in the sliding block, and a scalar rod is inserted into the rod hole. An anti-disengagement cap is fixedly connected to one end of the scalar rod. A second spring is fixedly connected between the anti-disengagement cap and the sliding block, and the second spring is sleeved on the scalar rod. On the measuring rod, during the grinding of the drill bit, a scalar mechanism can be set to adjust and move the measuring rod to the desired preset length position. During the grinding process, the measuring rod is always in contact with the side wall of the drill bit. As grinding progresses, the length of the drill bit will gradually shorten. When the other end of the drill bit moves to the measuring rod, it can provide timely and intuitive feedback that the drill bit has reached the preset length, reminding the operator to stop grinding in time to avoid over-grinding or under-grinding. It can accurately control the length of the drill bit after grinding, effectively ensuring that the length of the drill bit after grinding is consistent and meeting the precision requirements of the processing for the length of the drill bit.

[0009] The advantages of this utility model are:

[0010] This invention, when grinding a drill bit, incorporates a scalar mechanism that allows the scalar rod to be adjusted and moved to the desired preset length position. During grinding, the scalar rod remains in contact with the drill bit's sidewall. As grinding progresses, the drill bit's length gradually decreases. When the other end of the drill bit reaches the scalar rod, it provides timely and intuitive feedback that the drill bit has reached the preset length, reminding the operator to stop grinding promptly to avoid over-grinding or under-grinding. This allows for precise control of the drill bit's length after grinding, effectively ensuring consistent drill bit length and meeting the precision requirements for drill bit length in machining processes.

[0018] 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 scope of protection of the present utility model.

[0019] Please see Figure 1-3 and Figure 5As shown, a grinding device for drill bit processing includes a base 1, a fixed column 2 fixedly connected to the base 1, mounting plates 3 fixedly connected to both sides of the fixed column 2, motors 4 mounted on the outer walls of the two mounting plates 3, grinding wheels 5 mounted on the output ends of the two motors 4, a T-shaped groove 6 opened on the base 1, a T-shaped slide plate 7 slidably fitted in the T-shaped groove 6, a movable plate 8 fixedly connected to the top side of the T-shaped slide plate 7, two triangular limiting blocks 9 fixedly connected to the top side of the movable plate 8, two rod holes opened on the movable plate 8, movable rods 10 inserted into the two rod holes, a pressing plate 11 fixedly connected to the top of the two movable rods 10, two first springs 12 fixedly connected between the pressing plate 11 and the movable plate 8, and the two first springs 12 correspondingly sleeved on the movable rods 10, and rod caps 13 fixedly connected to the bottom ends of the two movable rods 10; during operation, the drill bit is ground. First, the drill bit to be ground is placed in the placement groove formed by the two triangular limiting blocks 9. Then, the pressing plate 11 is pressed down, the movable rod 10 moves down, the first spring 12 is compressed, and the pressing plate 11 presses and limits the drill bit to ensure that the drill bit is stable in position during the grinding process, avoiding shaking or deviation, and providing a basis for precise grinding. After the drill bit is pressed and limited, with the cooperation of the T-shaped groove 6 and the T-shaped sliding plate 7, a good guide is provided for the drill bit to move towards the grinding wheel 5, ensuring that the drill bit moves in a straight line and that its end accurately contacts the grinding wheel 5. When the end of the drill bit moves to contact the grinding wheel 5, the motor 4 is started to make the grinding wheel 5 rotate, so that the end of the drill bit can be ground. Through stable limiting and precise guidance, combined with the high-speed rotation of the grinding wheel 5, precise grinding of the end of the drill bit can be achieved, effectively ensuring the grinding quality.

[0020] Please see Figure 1 and Figure 4As shown, a scale mark 14 is installed on the top side of the base 1, and the scale mark 14 is located beside the T-shaped groove 6. A vertical plate 15 is fixedly connected to the base 1, and a sliding groove 16 is opened on the vertical plate 15. A sliding block 17 is slidably assembled in the sliding groove 16. A movable frame 18 is fixedly connected to the top side of the sliding block 17, and the movable frame 18 is slidably assembled on the top side of the vertical plate 15. A screw hole is opened on the movable frame 18, and a locking bolt 19 is rotatably assembled in the screw hole. The bottom end of the locking bolt 19 contacts the top side wall of the vertical plate 15. A rod hole is opened in the sliding block 17, and a scalar rod 20 is inserted through the rod hole. An anti-dislodgement cap 21 is fixedly connected to one end of the scalar rod 20. A second spring 22 is fixedly connected between the anti-dislodgement cap 21 and the sliding block 17, and the second spring 22 is sleeved on the scalar rod 20. During operation, when grinding the drill bit, in order to ensure that the drill bit length is consistent after grinding, a mechanism is designed to be used to ensure that the drill bit length is consistent after grinding. The scalar mechanism moves the sliding block 17 within the slide groove 16, which in turn moves the scalar rod 20 to align with the scale mark 14. When the scalar rod 20 reaches the desired position, the locking bolt 19 fixes the movable frame 18 in the current position, allowing the scalar rod 20 to be adjusted to the desired preset length. This provides a clear and convenient way to check whether the drill bit has reached the preset length. During the grinding process, the scalar rod 20 remains in contact with the drill bit's sidewall. As grinding progresses, the drill bit's length gradually decreases. When the other end of the drill bit reaches the scalar rod 20, it provides timely and intuitive feedback that the drill bit has reached the preset length, reminding the operator to stop grinding promptly to avoid over-grinding or under-grinding. This allows for precise control of the drill bit's length after grinding, ensuring consistent drill bit length and meeting the precision requirements for drill bit length in machining.

[0021] Working Principle: Existing drill bit grinding devices lack a scalar mechanism, making it impossible to accurately control the length of the drill bit after grinding. This easily leads to over-grinding or under-grinding, failing to meet the precision requirements for drill bit length. Therefore, to address these issues, a new drill bit grinding device is proposed. During drill bit grinding, to ensure consistent drill bit length after grinding, a scalar mechanism is incorporated. This mechanism moves the sliding block 17 within the groove 16, causing the scalar rod 20 to move and align with the scale mark 14. When the scalar rod 20... When moved to the desired position, the movable frame 18 is fixed in the current position by the locking bolt 19, thereby allowing the scalar rod 20 to be adjusted and moved to the desired preset length position. This facilitates intuitive and convenient feedback on whether the drill bit has reached the preset length. After the scalar rod 20 is adjusted, when grinding the drill bit, first place the drill bit to be ground in the placement groove formed by the two triangular limit blocks 9, then press down on the pressing plate 11, the movable rod 10 moves down, the first spring 12 is compressed, and the pressing plate 11 presses down on the drill bit. The limit switch ensures the drill bit's stable position during grinding, preventing wobbling or deviation and providing a foundation for precise grinding. After the drill bit is pressed into the limit switch, the T-slot 6 and T-slide plate 7 provide good guidance for the drill bit to move towards the grinding wheel 5, ensuring the drill bit moves in a straight line and its end accurately contacts the grinding wheel 5. When the end of the drill bit moves to contact the grinding wheel 5, the motor 4 is started, causing the grinding wheel 5 to rotate, thus enabling the grinding of the drill bit end. Through stable limiting and precise guidance, in conjunction with the grinding wheel 5... The high-speed rotation enables precise grinding of the drill bit tip, effectively ensuring grinding quality. During the grinding process, the scalar rod 20 remains in contact with the drill bit sidewall. As grinding progresses, the drill bit length gradually shortens. When the other end of the drill bit moves to the scalar rod 20, it provides timely and intuitive feedback that the drill bit has reached the preset length, reminding the operator to stop grinding in time to avoid over-grinding or under-grinding. It can precisely control the length of the drill bit after grinding, effectively ensuring that the drill bit length is consistent after grinding and meeting the precision requirements of the machining process for the drill bit length.
