Description

Technical Field

[0001] This utility model relates to the field of drill bit grinding, specifically to an automatic drill bit grinding device. Background Technology

[0002] Drill bits are devices used to drill holes in workpieces. Prolonged use of drill bits can lead to reduced sharpness, affecting drilling efficiency. Therefore, it is necessary to provide a grinding device that facilitates automatic grinding of drill bits. The "Automatic Drill Bit Grinding Machine" disclosed in application number "202322575555.6" represents an increasingly mature technology. Its features include: a telescopic motor driving a telescopic shaft to move back and forth, allowing the fixed drill bit to move back and forth for easy grinding of every part of the drill bit; fixing bolts that can be screwed into a fixing component to secure the drill bit; a cooling fan to dissipate heat generated during operation in the motor compartment, mounting compartment, and grinding compartment, preventing overheating and shutdown that would affect grinding efficiency; and a chip outlet to discharge chips generated during grinding, preventing chips from interfering with the grinding process. The machine compartment, installation compartment, and grinding compartment are equipped with glass at the front, allowing for constant observation of their working status and facilitating timely shutdown by operators to prevent accidents. However, this grinding equipment has the following drawbacks: While the telescopic motor driving the telescopic shaft facilitates drill bit grinding, this structure alone is insufficient for fully automatic grinding based on drill bit length, thus affecting grinding efficiency and quality. Therefore, a grinding device that enables fully automatic grinding of drill bits is necessary. Furthermore, the flying debris during drill bit grinding affects safety. Therefore, a grinding device that provides both heat dissipation and protection, improving safety, is also necessary. Utility Model Content

[0016] In one specific embodiment, the movable component 100, in conjunction with the grinding component 200, facilitates the control of the drill bit body 1036 to move laterally and longitudinally. This allows for comprehensive, seamless grinding of drill bits of different lengths, thereby improving grinding quality and efficiency.

[0020] In one specific embodiment, by activating the second cylinder 1025 in conjunction with the second push rod 1027, the second slider 1023 can be controlled to reciprocate along the second slide table 1022, thereby enabling the clamping mechanism 103 to be longitudinally adjusted, so as to make all-round adjustment of the position of the drill bit body 1036 and improve the grinding quality of the drill bit.

[0021] Please see Figure 4 The clamping mechanism 103 includes a first motor 1031 mounted on the upper end of the second slider 1023.

A cutter head clamping block 1034 is provided at the front end of the two mounting discs 1033. A fixing shell 1035 is sleeved on the side surface of the cutter head clamping block 1034. A drill bit body 1036 is installed inside the cutter head clamping block 1034.

[0022] In one specific embodiment, by starting the first motor 1031 to rotate the connecting shaft 1032, the cutter head clamp 1034 can be controlled to clamp and fix the drill bit body 1036, thereby improving the installation stability of the drill bit body 1036.

[0023] Please see Figures 2-4 A number of first buffer plates 111 are equidistantly installed on the side surface of the first slide table 1011.

[0027] The difference between this embodiment and Embodiment 1 is as follows: Please refer to... Figure 7 A protective component 300 is installed on the upper end of the first moving mechanism 101. The protective component 300 includes a protective plate 301 installed on one end of the first moving mechanism 101. A protective net 302 is embedded in the upper end of the protective plate 301. A connecting frame 303 is installed inside the protective plate 301. A micro motor 304 is installed inside the connecting frame 303. A cooling fan 305 is installed at the output end of the micro motor 304. A dustproof net 306 is installed inside the connecting frame 303.

[0028] In one specific embodiment, during use, the protective plate 301 and the protective net 302 can protect the moving component 100 and the grinding component 200, preventing the drill bit body 1036 from flying debris when being ground. Then, the micro motor 304 is started to rotate the cooling fan 305, which can help cool the drill bit body 1036, thus improving the safety of the grinding equipment.

[0029] Please see Figure 7 The protective plate 301 has a mounting groove 311 on its surface. The connecting frame 303 is installed inside the mounting groove 311. The output end of the micro motor 304 is fixedly connected to the limiting shaft 321. The surface of the cooling fan 305 has a limiting hole 322. The limiting shaft 321 is inserted into the limiting hole 322.

[0030] In one specific embodiment, the limiting shaft 321 is inserted into the limiting hole 322. When the micro motor 304 rotates the limiting shaft 321, it can also rotate the cooling fan 305 to facilitate heat dissipation for the grinding equipment.

[0031] Working principle: In use, the drill bit is first clamped and positioned by the clamping mechanism 103. At the same time, the first moving mechanism 101 is activated to move the second moving mechanism 102 and the clamping mechanism 103 laterally, thereby adjusting the position of the drill bit body 1036. Then, the second moving mechanism 102 is controlled to move the clamping mechanism 103 longitudinally, thereby moving the drill bit body 1036 closer to or further away. This allows the drill bit body 1036 to be brought into contact with the depth detector 202, thus adjusting the depth of the drill bit body 1036. Simultaneously, the third cylinder 205 is controlled to raise and lower the second motor 201, thereby adjusting the height of the grinding wheel 209. Finally, the mounting shaft 203 at the output end of the second motor 201 is activated to rotate, thereby rotating the grinding wheel 209. The grinding wheel 209 can perform all-round grinding of the drill bit body 1036 without dead angles, thereby improving the grinding quality and efficiency of the grinding equipment.
