Description

Technical Field

[0001] This utility model relates to the technical field of drill bit processing, and in particular to a drill bit straightening device. Background Technology

[0002] To replace the traditional method of manually hammering drill bits for straightening, various drill bit straightening devices have been disclosed in the prior art. For example, Chinese Utility Model Patent Publication No. CN214683603U discloses a drill bit straightening device, which includes: a frame with a pressure rod and a worktable located below the pressure rod; a positioning rod that is swayably disposed on the worktable; wherein, the worktable is provided with an arc-shaped placement groove for placing the drill bit, the positioning rod is located on both sides of the placement groove, a tension spring is provided below the positioning rod, the positioning rod is perpendicular to the axis of the drill bit, and the movable end of the positioning rod is pressed against the upper surface of the drill bit, thereby reducing the labor intensity of the worker.

[0003] The above-mentioned straightening device straightens the drill bit by using a placement slot and a pressure rod on the worktable. The drill bit is straightened in only one direction. When the same position of the drill bit is bent in multiple directions, the angle of the drill bit needs to be adjusted and straightened multiple times, resulting in low work efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a drill bit straightening device that can straighten drill bits in two directions simultaneously and has high working efficiency.

[0005] This utility model discloses a drill bit straightening device, comprising a base plate, two support blocks, a pressure head frame, and a stamping mechanism. The two support blocks are mounted opposite each other on the base plate, and a straightening placement groove is provided on the upper middle surface of the two support blocks. The pressure head frame is mounted on the middle of the base plate, and the stamping mechanism is mounted on the pressure head frame, with a downward-facing pressure head. It also includes a first shaft seat, a first support plate, a second shaft seat, and a second support plate. The first shaft seat is mounted in the middle of the base plate, and the outer end of the first support plate is rotatably mounted on the first shaft seat. The second shaft seat is mounted in the middle of the base plate, and the outer end of the second support plate is rotatably mounted on the second shaft seat. The first and second support plates are located in the middle of the two support blocks and below the pressure head of the stamping mechanism. The inner end of the first support plate has a first groove, and the inner end of the second support plate has a second groove. The first and second grooves are arranged alternately. When the first and second support plates are flat, the first and second grooves are aligned with the drill bit. The axes are concentric; during operation, when the middle part of the drill bit bends in two directions, the two ends of the drill bit are placed in the placement slots of the two support blocks, so that the protrusion of the drill bit in one direction faces upward, the middle part of the drill bit is inserted into the slot one of support plate one and the slot two of support plate two, and the protrusion of the drill bit in the other direction faces support plate one or support plate two. The stamping mechanism extends the pressure head downward, so that the pressure head pushes the inner ends of support plate one and support plate two downward, so that support plate one and support plate two are pressed to a horizontal state. During this process, the middle part of the drill bit is pressed downward by the pressure head in conjunction with the support of the two support blocks, thereby straightening the vertical bending of the drill bit. At the same time, support plate one and support plate two are pressed from the inclined state to the horizontal state, so that slot one and slot two straighten the bending of the drill bit in the horizontal direction. Compared with the existing technology, it can straighten the drill bit in two directions, and the working efficiency is high.

[0006] Preferably, it also includes two spring plates, the outer ends of which are mounted on the base plate, and the inner ends of which are connected to support plate one and support plate two respectively. The elastic force of the two spring plates causes the inner ends of support plate one and support plate two to tilt upward. By installing two spring plates, support plate one and support plate two are kept tilted. After the pressure head of the stamping mechanism rises, support plate one and support plate two tilt to push the drill bit up, which facilitates material unloading.

[0007] Preferably, it also includes a vertical plate, a gripper disk, and a motor. The vertical plate is mounted on the base plate, the gripper disk is rotatably mounted on the left side wall of the vertical plate, and the motor is mounted on the right side wall of the vertical plate. The output shaft of the motor is connected to the gripper disk for transmission. The end of the drill bit is clamped in the gripper disk, and the motor drives the gripper disk to rotate, thereby adjusting the placement angle of the drill bit.

[0008] Preferably, it also includes multiple laser heads, which are evenly mounted circumferentially on the end of the gripper disk. After the drill bit is clamped into the gripper disk, the multiple laser heads turn on to emit laser beams. Multiple laser beams are arranged around the drill bit. By detecting the distance between the outer wall of the drill bit and the multiple laser beams, the bending of the drill bit is detected, thereby improving the straightening effect.

[0009] Preferably, it also includes a slide table and a lifting seat. The slide table is horizontally movable and installed on the base plate, the lifting seat is vertically installed on the slide table, and the upright plate is vertically movable and installed on the lifting seat. After the drill bit is clamped onto the jaw plate, the slide table moves along the base plate, thereby driving the drill bit to move and adjust the straightening position of the drill bit. When the drill bit is raised and lowered, the upright plate rises and falls adaptively along the lifting seat to improve practicality. After the upright plate rises along the lifting seat, the jaw plate lifts the drill bit out of the support plate one and support plate two, which facilitates unloading and loading.

[0010] Preferably, it also includes two guide slopes, with guide slopes provided on the upper edge of the first slot of the first support plate and the upper edge of the second slot of the second support plate; by providing two guide slopes, it is convenient to insert the drill bit into the first slot of the first support plate and the second slot of the second support plate.

[0011] Preferably, it also includes two baffles, with baffles provided at the lower edge of the first slot of the first support plate and the lower edge of the second slot of the second support plate; when the drill bit is placed in the first slot of the first support plate and the second slot of the second support plate, the two baffles block the lower wall of the drill bit, preventing the drill bit from falling out of the first slot of the first support plate and the second slot of the second support plate.

[0012] Compared with the prior art, the advantages of this utility model are: it can straighten the drill bit in two directions, resulting in high work efficiency. Attached Figure Description

[0020] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0021] Example 1

[0022] like Figures 1 to 5 As shown, a drill bit straightening device includes a base plate 1, two support blocks 2, a pressure head frame 3, and a stamping mechanism 4. The two support blocks 2 are mounted opposite each other on the base plate 1, and a straightening placement groove is provided on the upper surface of the middle part of the two support blocks 2. The pressure head frame 3 is mounted on the middle part of the base plate 1, and the stamping mechanism 4 is mounted on the pressure head frame 3. The stamping mechanism 4 is provided with a downward pressure head. It also includes a first shaft seat 5, a first support plate 6, a second shaft seat 7, and a second support plate 8. The first shaft seat 5 is mounted on the middle part of the base plate 1, and the outer end of the first support plate 6 is rotatably mounted on the first shaft seat 5. The second shaft seat 7 is mounted on the middle part of the base plate 1, and the outer end of the second support plate 8 is rotatably mounted on the second shaft seat 7. The first support plate 6 and the second support plate 8 are located in the middle of the two support blocks 2, and the first support plate 6 and the second support plate 8 are located on the pressure head of the stamping mechanism 4. Below the head, the inner end of support plate 1 6 is provided with slot 1, and the inner end of support plate 2 8 is provided with slot 2. Slot 1 and slot 2 are arranged alternately. When support plate 1 6 and support plate 2 8 are flat, slot 1 and slot 2 are concentric with the axis of the drill bit. It also includes two spring plates 9. The outer ends of the two spring plates 9 are installed on the base plate 1, and the inner ends of the two spring plates 9 are connected to support plate 1 6 and support plate 2 8 respectively. The elastic force of the two spring plates 9 causes the inner ends of support plate 1 6 and support plate 2 8 to tilt upward. It also includes two guide slopes 16. The upper edge of slot 1 of support plate 1 6 and the upper edge of slot 2 of support plate 2 8 are both provided with guide slopes 16. It also includes two baffles 17. The lower edge of slot 1 of support plate 1 6 and the lower edge of slot 2 of support plate 2 8 are both provided with baffles 17.

[0023] During operation, when the middle of the drill bit bends in two directions, both ends of the drill bit are placed in the placement slots of the two support blocks 2, so that the protrusion of the drill bit in one direction faces upward. By setting two guide slopes 16, it is convenient for the drill bit to be placed into the slot one of support plate 1 6 and the slot two of support plate 2 8. The middle of the drill bit is inserted into the slot one of support plate 1 6 and the slot two of support plate 2 8. After the drill bit is placed into the slot one of support plate 1 6 and the slot two of support plate 2 8, the two baffles 17 block the lower wall of the drill bit to prevent the drill bit from falling out of the slot one of support plate 1 6 and the slot two of support plate 2 8, and make the protrusion of the drill bit in the other direction face support plate 1 6 or support plate 2 8. The stamping mechanism 4 extends the pressure head downward. The pressure head pushes the inner ends of support plate 6 and support plate 8 downwards, pressing them to a horizontal position. During this process, the middle part of the drill bit is pressed down by the pressure head and supported by two support blocks 2, thereby straightening the vertical bending of the drill bit. At the same time, support plate 6 and support plate 8 are pressed from an inclined state to a horizontal state, thus straightening the horizontal bending of the drill bit through slots 1 and 2. By installing two spring plates 9, support plate 6 and support plate 8 are kept inclined. After the pressure head of the stamping mechanism 4 rises, support plate 6 and support plate 2 tilt and push the drill bit up, facilitating material unloading. Compared with the prior art, this method can straighten the drill bit in two directions, resulting in high work efficiency.

[0024] Example 2

[0025] like Figure 1 , Figure 2 and Figure 3 and Figure 6 As shown, based on Embodiment 1, it also includes a vertical plate 10, a gripper disk 11, and a motor 12. The vertical plate 10 is mounted on the base plate 1, the gripper disk 11 is rotatably mounted on the left side wall of the vertical plate 10, and the motor 12 is mounted on the right side wall of the vertical plate 10. The output shaft of the motor 12 is connected to the gripper disk 11 for transmission. It also includes multiple laser heads 13, which are evenly mounted on the ends of the gripper disk 11. It also includes a slide table 14 and a lifting seat 15. The slide table 14 is horizontally movable and mounted on the base plate 1, the lifting seat 15 is vertically mounted on the slide table 14, and the vertical plate 10 is vertically movable and mounted on the lifting seat 15.

[0026] The end of the drill bit is clamped into the gripper plate 11. Multiple laser heads 13 are turned on to emit laser beams. Multiple laser beams are arranged around the drill bit. The bending condition of the drill bit is detected by detecting the distance between the outer wall of the drill bit and the multiple laser beams. The motor 12 drives the gripper plate 11 to rotate, thereby adjusting the placement angle of the drill bit. The slide table 14 moves along the base plate 1, thereby moving the drill bit and adjusting the straightening position of the drill bit. When the drill bit is raised and lowered, the upright plate 10 is raised and lowered along the lifting seat 15. After the upright plate 10 is raised along the lifting seat 15, the drill bit is lifted out of the support plate 6 and the support plate 8 by the gripper plate 11, which facilitates unloading and loading.

[0027] like Figures 1 to 6 As shown, this utility model discloses a drill bit straightening device. During operation, the end of the drill bit is first clamped into the gripper disc 11. The motor 12 drives the gripper disc 11 to rotate, causing the protrusion of the drill bit in one direction to face upwards and the protrusion in the other direction to face either support plate 6 or support plate 8. The slide table 14 moves along the base plate 1, thereby moving the drill bit and adjusting its straightening position. Then, the upright plate 10 descends along the lifting seat 15, placing both ends of the drill bit into the placement slots of the two support blocks 2, so that the middle part of the drill bit is engaged in the slot 1 of support plate 6 and the slot 2 of support plate 8. The stamping mechanism 4 extends the pressure head downwards, causing the pressure head to press against support plate 6 and support plate 8. The inner end is pushed downward, causing support plate 6 and support plate 8 to be pressed to a horizontal state. During this process, the middle part of the drill bit is pressed downward by the pressure head in conjunction with the support of the two support blocks 2, thereby straightening the vertical bending of the drill bit. At the same time, support plate 6 and support plate 8 are pressed from an inclined state to a horizontal state, thereby straightening the horizontal bending of the drill bit through slots 1 and 2. After the drill bit is pulled out from slot 1 of support plate 6 and slot 2 of support plate 8, multiple laser heads 13 are activated to emit laser beams. Multiple laser beams are arranged around the drill bit. By detecting the distance between the outer wall of the drill bit and the multiple laser beams, the bending condition of the drill bit is detected. Finally, the unqualified parts are straightened again.

[0028] The main functions achieved by this utility model are:

[0029] 1. It can straighten the drill bit in two directions simultaneously, resulting in high work efficiency;

[0030] 2. It can adjust the straightening position and angle of the drill bit;

[0031] 3. By setting multiple laser heads 13, it is convenient to detect the bending of the drill bit and improve the straightening effect.
