Description

Technical Field

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

[0002] Machining is essential for industrial production. Common mechanical cutting and drilling all require drill bits. Drill bits will wear down during use. When a worn drill bit is used for cutting or drilling, it will reduce the efficiency of drilling and cutting, and at the same time reduce the precision of the parts produced. Therefore, drill bits need to be sharpened before use to keep them sharp.

[0003] According to a drill bit grinding device disclosed in the above application (publication number: CN216829965U), the drill bit is fixed to the locking head by a sliding sleeve slidably connected to the sliding rod, a rotary table fixed on the sliding sleeve, a support arm installed on the rotary table, a handle set at the end of the support arm away from the rotary table and hinged to the support arm, and a locking head fixed at one end of the handle. The support arm can move horizontally and can rotate left and right under the action of the rotary table. The handle is hinged to the support arm, so that the handle can rotate up and down. The sliding rod is rotatably connected to the support table, so that the drill bit can be close to the grinding wheel and away from the grinding wheel, and the drill bit can be ground at multiple angles.

[0004] However, despite the device's excellent performance in grinding, some problems still exist in actual operation. Particularly during drill bit grinding, a large amount of shavings are generated. These shavings often fall onto the workbench, not only polluting the working environment but also increasing the difficulty of subsequent cleaning. Current practices typically require operators to manually clean up these shavings, which is time-consuming, labor-intensive, and inefficient. More seriously, during the cleaning process, the shavings are easily carried away by the cleaning tools, scattering everywhere and further affecting the cleaning effect and efficiency.

An L-shaped plate is fixed at the top, and an abutment rod is fixed on the left side of the inner wall of the main body. When the fixed frame is located at the far right of the collection box, the surface of the abutment plate abuts against the inner wall of the collection box. Through the abutment plate, the movable plate, and the fixed plate, the scraper moves upward synchronously. The L-shaped plate limits the card plate, and the scraper disengages from the bottom inner side of the main body. When the fixed frame is located at the far left inner wall of the main body, the abutment rod is inserted into the insertion hole, and the surface of the abutment rod abuts against the surface of the card plate. At this time, the card plate disengages from the L-shaped plate, and the spring-loaded scraper moves down to reset and re-fits against the bottom inner side of the main body.

[0012] Preferably, the cleaning component includes a third cylinder, which is fixed to the left side surface of the main body. The output end of the third cylinder passes through the main body and is fixed to a fixed frame. A scraper is slidably connected to the inner wall of the fixed frame.

[0015] Preferably, the end of the card plate away from the second spring is set as an inclined surface, which does not affect the normal upward movement of the scraper.

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

[0017] 1. This grinding device for manufacturing drill bit stock, through the setting of limiting components, when the fixed frame is located at the rightmost side of the collection box, the surface of the contact plate abuts against the inner wall of the collection box. Through the movable plate and the fixed plate, the scraper moves upward, and the side of the clamping plate away from the inclined plane abuts against the surface of the L-shaped plate. At this time, the L-shaped plate limits the clamping plate, and the scraper disengages from the inner bottom of the main body. When the fixed frame is located at the leftmost inner wall of the main body, the contact rod is inserted into the insertion hole, and at the same time, the surface of the contact rod abuts against the surface of the clamping plate. At this time, the clamping plate disengages from the L-shaped plate.

[0027] like Figures 1-7 As shown, this utility model provides a technical solution: a grinding device for manufacturing drill bit rods, including a main body 1. The surface and interior of the main body 1 are provided with a cleaning component 8 and a limiting component 9. The cleaning component 8 includes: a fixed frame 81 and a scraper 82; the limiting component 9 includes: a fixed plate 90, a movable plate 91, a contact plate 92, a clamping plate 93, a connecting plate 94, a spring 95, a socket 96, an L-shaped plate 97, and a contact rod 98.

[0028] A fixed plate 90 is fixed to the top of the scraper 82. A movable plate 91 is hinged to the surface of the fixed plate 90. An abutment plate 92 is hinged to the end of the movable plate 91 away from the fixed plate 90. The end of the abutment plate 92 away from the movable plate 91 passes through the fixed frame 81 and is slidably connected to the fixed frame 81. A retaining plate 93 is slidably connected to the top of the scraper 82. A second spring 95 is fixed to the surface of the scraper 82. A connecting plate 94 is fixed to the end of the second spring 95 away from the scraper 82 and is fixed to the top of the scraper 82. An insertion hole 96 is opened on the surface of the fixed frame 81. An L-shaped plate 97 is fixed to the top of the inner wall of the fixed frame 81. An abutment rod 98 is fixed to the left side of the inner wall of the main body 1. The end of the retaining plate 93 away from the second spring 95 is provided with... The inclined plane is such that when the fixed frame 81 is located at the rightmost side of the collection box 84, the surface of the contact plate 92 contacts the inner wall of the collection box 84. The contact plate 92 drives the movable plate 91 to flip, pulling the fixed plate 90 and the scraper 82 to move upwards simultaneously. The side of the clamping plate 93 away from the inclined plane contacts the surface of the L-shaped plate 97, which allows the L-shaped plate 97 to limit the clamping plate 93. The scraper 82 disengages from the inner bottom of the main body 1. When the fixed frame 81 is located at the leftmost inner wall of the main body 1, the contact rod 98 is inserted into the insertion hole 96. At the same time, the surface of the contact rod 98 contacts the surface of the clamping plate 93. At this time, the clamping plate 93 disengages from the L-shaped plate 97. When the fixed frame 81 continues to move to the right, the spring 83 is released, thereby driving the scraper 82 to move down and reset, re-attaching to the inner bottom of the main body 1.

[0029] The cleaning component 8 includes a cylinder 3 80, which is fixed to the left side surface of the main body 1. The output end of the cylinder 3 80 passes through the main body 1, and a fixing frame 81 is fixed to the output end of the cylinder 3 80. A scraper 82 is slidably connected to the inner wall of the fixing frame 81. A spring 83 is fixed to the top of the scraper 82, and the top of the spring 83 is fixed to the top of the inner wall of the fixing frame 81. A collection box 84 is installed on the right side of the main body 1. The collection box 84 is interconnected with the main body 1, and a door 85 is installed on the surface of the collection box 84. When the cylinder 3 80 is opened, the fixing frame 81 moves to the right, and the bottom of the scraper 82 contacts the bottom of the inner side of the main body 1, so that the waste can be scraped and cleaned. At the same time, the scraped waste falls into the collection box 84.

[0030] A cylinder 10 is fixed to the right side surface of the main body 1. The output end of the cylinder 10 passes through the main body 1, and a clamp 11 is fixed to the output end of the cylinder 10. A cylinder 2 is fixed to the top of the main body 1. The output end of the cylinder 2 passes through the main body 1. A connecting seat 3 is fixed to the bottom of the output end of the cylinder 2. A movable seat 4 is rotatably connected to the inside of the connecting seat 3. A motor 7 is fixed to the surface of the connecting seat 3. The output shaft of the motor 7 passes through the connecting seat 3 and the movable seat 4, and the output shaft of the motor 7 is fixedly connected to the movable seat 4. A motor 5 is fixed to the bottom of the movable seat 4. A grinding plate 6 is fixed to the bottom of the output shaft of the motor 5. The drill bit is clamped and fixed by the clamp 11. By opening the cylinder 2, the motor 5 can be driven to move down, so that the grinding plate 6 contacts the surface of the drill bit. When the motor 5 is turned on, the drill bit can be ground. When the grinding angle needs to be adjusted, the angle of the motor 7 can be adjusted by turning the motor 7 forward or backward.

[0031] When grinding the drill bit stock is required, the drill bit is clamped and fixed by clamp 11. Activating cylinder 2 moves motor 5 downwards, causing the grinding plate 6 to contact the drill bit surface. Activating motor 5 initiates the grinding operation. To adjust the grinding angle, motor 7 rotates forward or backward, adjusting the angle of motor 5. The resulting debris falls to the bottom inner side of the main body 1. To clean the debris, cylinder 8 is activated. When the fixed frame 81 moves to the right, the bottom of the scraper 82 contacts the bottom of the inner side of the main body 1, thus scraping and cleaning the waste. The scraped waste falls into the collection box 84. When the fixed frame 81 is at the rightmost side of the collection box 84, the surface of the contact plate 92 contacts the inner wall of the collection box 84. The contact plate 92 then causes the movable plate 91 to flip, pulling the fixed plate 90 upwards. This simultaneously moves the scraper 82 upwards. At this time, the spring 83 is compressed, and the inclined surface of the clamping plate 93 contacts the L... When the L-shaped plate 97 is in contact with the surface, spring 95 is compressed. When the clamping plate 93 is above the L-shaped plate 97, spring 95 is released, and clamping plate 93 returns to its original position. At this time, the side of clamping plate 93 away from the inclined plane is in contact with the surface of the L-shaped plate 97, thus limiting the clamping plate 93 to the L-shaped plate 97. At this time, scraper 82 is disengaged from the inner bottom of the main body 1. When cylinder 80 is opened and retracted, scraper 82 can be prevented from moving waste synchronously, thus avoiding affecting the cleaning effect. When the fixing frame 81 is located on the leftmost inner wall of the main body 1, this... When the contact rod 98 is inserted into the socket 96, the surface of the contact rod 98 contacts the surface of the card plate 93. At this time, the card plate 93 disengages from the L-shaped plate 97. When the fixed frame 81 continues to move to the right, the spring 83 is released, thereby driving the scraper 82 to move down and reset to re-fit against the inner bottom of the main body 1. Thus, when the cylinder 80 reciprocates, the scraper 82 intermittently fits against the inner side of the main body 1, preventing waste from being moved and improving cleaning efficiency. Personnel can clean the inside of the collection box 84 by opening the box door 85.

[0032] 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.
