The center of the driven wheel 203 is penetrated by a tool mounting hole 204, and the tool mounting hole 204 is a hexagonal prism-shaped through hole. The grinding tool 30 is fixed in the tool mounting hole 204 and its top surface is higher than the tool mounting hole 204. The grinding tool 30 is recessed with a grinding tool nest 301 on the upper and lower sides. The transmission housing 201 is provided with an insertion hole 60 for the electrode cap to extend into the grinding tool nest 301 at a position corresponding to the grinding tool nest 301. The output shaft end of the motor 10 is connected to the driving wheel 202 of the transmission mechanism 20, that is, the motor 10 provides a power source to the driving wheel 202 so that the driving wheel 202 can rotate. Since the driving wheel 202 and the driven wheel 203 are rotatably connected, the motor 10 can drive the driven wheel 203 to rotate. The outer periphery of the grinding tool 30 is aligned with the tool mounting hole 301. The mounting hole 204 matches the grinding tool 30, and the grinding tool 30 is fixed in the tool mounting hole 204, so the rotation of the motor 10 can drive the grinding tool 30 to rotate so as to facilitate the subsequent grinding of the electrode cap. When the electrode cap is being ground, the electrode cap is inserted into the grinding tool nest 301 through the insertion hole 60 on the transmission housing 201 for grinding; the transmission housing 201 has a structure formed by the transmission housing 201, the driven wheel 203 and the grinding tool 203. The side wall of the transmission housing 201 is provided with an air blowing hole 205, which is communicated with the guide cavity 213; the inner wall of the tool mounting hole 204 is provided with at least one air guide groove 206, and the side wall of the grinding tool 30 is provided with at least one air inlet hole 302, which is located in the middle part of the side wall of the grinding tool 30, the air guide groove 206 corresponds to the air inlet hole 302, and the air inlet hole 302 is communicated with the grinding tool nest 301;In the above technical solution, since the driven wheel 203 and the grinding tool 203 are always in a rotating state during the grinding process, the blowing hole 205 is opened on the side wall of the transmission housing 201, and the blowing hole 205 on the side wall is connected to an external blowing device. The blowing device blows high-speed gas into the guide cavity 213 through the blowing hole 205. The guide cavity 213 is a closed cavity. Then, by opening an air guide groove 206 on the inner wall of the tool mounting hole 204, the high-speed gas inside the guide cavity 213 is The gas can be guided through the air guide groove 206, and the air guide groove 206 corresponds to the air inlet 302 of the grinding tool 30, and the high-speed gas enters the air inlet 302, and the air inlet 302 is connected to the grinding tool nest 301. At this time, a blowing path consisting of the blowing device-blowing hole 205-guiding cavity 213-air guide groove 206-air inlet 302-grinding tool nest 301 is formed, realizing an internal blowing structure for blowing directly into the grinding tool nest 301. Therefore, the airflow of the technical solution passes through the transmission The shell 201 enters the interior of the grinding tool nest 301 and blows from the inside to the outside, which fundamentally avoids the situation where the inside of the tool nest cannot be blown, and avoids the situation of chip blockage in the tool nest to the greatest extent; it is worth noting that the height of the bottom of the air guide groove 206 is consistent with the height of the bottom of the air inlet hole 302, that is, the air guide groove 206 extends from top to bottom on the inner wall of the tool mounting hole 204 to the middle of the inner wall of the tool mounting hole 204, so that high-speed gas will not flow out from the bottom; as a preferred embodiment of the present technical solution, the air guide groove 206 06 is two, the number of the air inlet holes 302 is also two, the two air guide grooves 206 are symmetrically arranged, the two air inlet holes 302 are also symmetrically arranged, one air guide groove 206 corresponds to one air inlet hole 302, and by setting two sets of air inlet guide structures, a high-speed airflow can be blown toward the center of the grinding knife nest 301, so that the cut waste chips are blown out of the grinding knife nest 301 from the inside to the outside by the high-speed airflow, avoiding the waste chips from being deposited inside the grinding knife nest 301, improving the grinding efficiency of the electrode cap, and extending the service life of the device. ;

[0043] See also Figure 5 and Figure 6As shown, an intermediate wheel 207 is further provided between the driving wheel 202 and the driven wheel 203. The driving wheel 202, the intermediate wheel 207 and the driven wheel 203 are all gears. The driving wheel 202 is meshed with the intermediate wheel 207, and the intermediate wheel 207 is meshed with the driven wheel 203. Therefore, the transmission mechanism 20 of the present technical solution operates in the following manner: the driving wheel 202 is driven by the motor 10 to rotate, and then the driven wheel 203 is rotated through the intermediate wheel 207. The grinding tool 30 is fixed in the driven wheel 203. Therefore, the motor 10 drives the grinding tool 30 to rotate so that the motor 10 drives the grinding tool 30 to rotate. The pole cap enters the grinding tool nest 301 for grinding; the transmission housing 201 includes an upper cover 208 and a lower cover 209, and a transmission cavity for placing the driving wheel 202, the intermediate wheel 207 and the driven wheel 203 is formed between the upper cover 208 and the lower cover 209. The transmission cavity is mainly used to place the driving wheel 202, the intermediate wheel 207 and the driven wheel 203. The transmission cavity includes three parts, namely the driving wheel placement cavity, the intermediate wheel placement cavity and the driven wheel placement cavity, and the three placement cavities are interconnected; it is worth noting that the blowing hole 205 is arranged on the side wall of the upper cover 208.

[0044] See also Figures 3 to 7 As shown, the upper cover 208 and the lower cover 209 are both provided with a through hole 210 at the position corresponding to the driven wheel 203. The through hole 210 is also provided with a mounting groove 211 on the side away from the driven wheel 203. The mounting groove 211 is mainly used for mounting the gland. The insertion hole 60 is opened at the center of the gland. Figure 5 and Figure 6 As shown, the upper and lower ends of the driven wheel 203 are fixed with pressure covers, and the pressure cover is connected to the driven wheel by locking screws. The upper and lower ends of the driven wheel 203 are in close contact with the pressure cover, that is, during the grinding process, the driven wheel 203, the grinding tool 30 and the pressure cover rotate together. A felt washer is also fixed in the mounting groove 211, and the felt washer is located between the mounting groove 211 and the pressure cover. The upper and lower ends of the driven wheel 203 are fixed with pressure covers, which are mainly used to prevent the driven wheel 203 and the grinding tool 30 from being rotated during the working process. The tool 30 moves. For the specific installation of the gland, please refer to the electrode cap grinding and shaping machine disclosed in patent document "202221026112.0". It should be noted that the inner diameter of the insertion hole 60 is smaller than the aperture of the tool installation hole 204; the cross-section of the driven wheel 203 is a "cross" structure, and the diameters of the top and bottom surfaces of the driven wheel 203 are both larger than the aperture of the through hole 210. A felt gasket 212 is also provided between the driven wheel 203 and the through hole 210. For details, please refer to Figure 6As shown, bearings are sleeved on the outer sides of the upper and lower ends of the driven wheel 203, which can make the driven wheel 203 rotate more smoothly inside the transmission housing 201. The felt washer 212 located at the top is in contact with the top surface of the driven wheel 203 and the bearing located at the top, and the felt washer 212 located at the bottom is in contact with the bottom surface of the driven wheel 203 and the bearing located at the bottom. The felt washer 212 mainly plays the role of sealing and preventing oil leakage. Through the felt washer 212 and the felt washer at the pressure cover, the sealing effect of the guide cavity 213 is greatly enhanced to prevent gas leakage; the blowing hole 205 is arranged at the upper cover 208, and the blowing hole 205 is connected with the through hole 210 from the side wall of the upper cover 208. Due to the presence of the pressure cover and the top surface of the driven wheel 203, the inner surface of the transmission housing 201 is formed It forms an annular guide cavity 213 composed of the upper cover 208, the driven wheel 203, the grinding tool 30 and the pressure cover. When the external high-speed airflow enters the guide cavity 213, the high-speed airflow is guided by the air guide groove 206 to blow air from the air inlet 302 to the grinding tool nest 301 to remove waste chips. It should be noted here that although the driven wheel 203 and the grinding tool 30 are always rotating in the working state, the air source can smoothly enter the grinding tool nest 301 through the guidance of the air guide groove 206 and the air inlet 302 for blowing. It is worth noting that the upper and lower ends of the intermediate wheel 207 are also provided with bearings. As for the rest of the internal structure of the transmission mechanism 20, this technical solution will not be redundantly described. For those skilled in the art, this design belongs to conventional design.

[0045] See also Figure 8 As shown, the grinding tool 30 includes a tool holder 303, which is a hexagonal column structure. The upper and lower sides of the tool holder 303 are both concavely provided with a grinding tool nest 301 with a hemispherical structure, and the bottom surface of the grinding tool nest 301 is a plane; the interior of the tool holder 303 is penetrated by two symmetrically arranged chip removal holes 304, one of which is fixed with a main cutting edge 305, and the other is fixed with a secondary cutting edge 306, and the air inlet 302 is symmetrical to the chip removal hole 304. The main cutting edge 305 and the secondary cutting edge 306 cooperate with the grinding tool nest 301 to grind the electrode cap. The chip removal hole 304 is mainly used for chip removal, so that waste chips will not be deposited inside the grinding tool nest 301. Moreover, since the air inlet hole 302 is connected to the chip removal hole 304, the external high-speed airflow blows from the chip removal hole 304 into the grinding tool nest 301, thereby blowing the waste chips to the outside. Moreover, the setting of the chip removal hole 304 can also improve the heat dissipation effect and extend the service life of the grinding tool 30.

[0046] See also Fig. 9 and Fig.10As shown, the main cutting edge 305 is a T-shaped structure, and its upper and lower side walls are both arc-shaped, and the upper and lower side walls of the main cutting edge 305 are provided with a plurality of first cutting edges 307 and a plurality of first chip breaking grooves 308, the first cutting edge 307 rotates to achieve the main cutting and supporting effect on the end face and the arc surface of the electrode cap, and the first chip breaking groove 308 breaks the waste chips in the cutting process and guides them to the chip removal hole 304 of the tool holder 303; the secondary cutting edge 306 is a T-shaped structure, and its upper and lower side walls are both arc-shaped, and the upper and lower side walls of the secondary cutting edge 306 are provided with a plurality of second cutting edges 309 and a plurality of second chip breaking grooves 310, the second cutting edge 309 rotates to achieve the secondary cutting and supporting effect on the cross section and the arc surface of the electrode cap, and the second chip breaking groove 310 The waste chips generated during the process are broken and guided to the chip removal hole 304 of the tool holder 303; the main and secondary cutting edges are both single-sidedly sharpened to increase the tool back angle. On the one hand, it increases the sharpness of the blade cutting, and on the other hand, it can guide the generated waste chips. It can match different cutting thicknesses under different cutting conditions, and the chip removal density and chip removal effect are good. A relatively abundant chip removal hole is left between the main and secondary cutting edges. The chip removal hole can quickly remove the waste chips generated during the cutting process without affecting the overall strength of the tool holder; the above is an implementation method of the main cutting edge and the secondary cutting edge, but it does not mean that the present technical solution can only adopt the main cutting edge and the secondary cutting edge of the above structure. The structural description of the main cutting edge and the secondary cutting edge is only used to understand the present technical solution.

[0047] In the above technical solution, it should be noted that the internal air blowing mechanism of the grinding machine proposed in this technical solution mainly protects the internal air blowing structure part, which is mainly realized around the air blowing hole 205, the air guide groove 206, and the air inlet hole 302.

[0048] See also Fig.11 and Fig.12As shown, the chip collecting device of the grinding machine includes the above-mentioned blowing mechanism in the grinding machine, and also includes a dust collecting shell 40, one of the side walls of the dust collecting shell 40 has an opening 401 for the transmission mechanism 20 to extend into, and the interior of the dust collecting shell 40 has a cavity, which provides a space for the grinding machine to grind the electrode cap, and the opening 401 of the dust collecting shell 40 moves toward the transmission mechanism 20 until it covers the grinding tool 30 of the transmission mechanism 20; the upper and lower surfaces of the dust collecting shell 40 are fixed with a barrier 50 for preventing waste chips from flying out, and the central part of the barrier 50 has a guide hole 501 for inserting the electrode to be ground, and the guide hole 501 on the barrier 50 The hole 501 allows the electrode to be ground to smoothly enter the dust collecting shell 40 for grinding. At the same time, the barrier 50 can also prevent the waste chips generated by grinding from flying out of the dust collecting shell 40. In addition, when the grinding process is completed, due to the existence of the barrier 50, the waste chips on the electrode can be brushed off, which greatly improves the chip collection efficiency and prevents the waste chips from flying out. The dust collecting shell 40 is connected to the blowing device, and the dust collecting shell 40 also has a chip discharge port. The chip discharge port 404 is connected to the chip collecting barrel through a pipeline. The chip discharge port 404 is located on the right side of the dust collecting shell 40, and the blowing device is connected to the left side of the dust collecting shell 40, so that the blowing device blows the dust collecting shell 40 to the dust collecting shell 40. Air is blown inside; the working principle of the present technical solution is as follows: the dust collecting shell 40 is connected to the blowing device, and the dust collecting shell 40 is also provided with a chip discharge port 404, and the chip discharge port is connected to the chip collecting bucket through a pipeline. When the present technical solution is actually used, the grinding mechanism of the grinding machine is first extended into the dust collecting shell 40 through the opening 401 of the dust collecting shell 40 and fixed, and then the electrode to be ground is extended into the dust collecting shell 40 through the guide hole 501, and then the grinding machine is started to grind the electrode. During the grinding process, the blowing device works to blow air into the dust collecting shell 40, and the waste chips from grinding enter the pipeline through the chip discharge port through the action of the blowing device until The waste chips enter the chip collecting barrel. During this working process, due to the existence of the barrier 50, the waste chips can be prevented from flying out to a great extent. When the electrode is finished grinding, the electrode is separated from the barrier 50, and the waste chips stuck on the electrode can be brushed off by relying on the barrier 50. Moreover, when the blowing device is running, the internal blowing device is connected to the external air source and also works to blow air into the grinding tool nest 301, so as to blow out the waste chips. By combining the internal blowing with the external blowing, the waste chips inside the grinding tool nest 301 can be blown out to prevent the waste chips from being deposited. The blown waste chips are uniformly collected by the chip collecting barrel, and there will be no chip blockage. At the same time, the unified collection of waste chips can also avoid affecting the workshop environment.

[0049] The upper and lower surfaces of the dust collecting shell 40 are both transparent cover plates 402, and a mounting hole is opened in the middle of the transparent cover plate 402. The annular barrier cover plate fixes the barrier member 50 on the mounting hole. The barrier member 50 is a circular brush, which can brush the waste chips off the electrode cap. The dust collecting shell 40 includes a main frame, and transparent cover plates are fixed on the upper, lower and rear sides of the main frame. The setting of the transparent cover plate is convenient for observing the collection of copper chips, so that the blowing device can be turned off in time after the copper chips inside the dust collecting shell are collected, so as to save energy.
