Description

Technical Field

[0001] This invention relates to the field of grinding equipment technology, and in particular to a milling cutter grinding device and its usage method for milling the frame of a mobile phone. Background Technology

[0002] After a period of use, the main cutting edge and the bottom cutting edge of a milling cutter will experience varying degrees of wear, affecting the surface finish, machining dimensions, and milling speed of the workpiece. Continued use can easily lead to tool breakage or even damage to the dimensions and shape of the workpiece, and in severe cases, can cause personal injury to the operator. Currently, the repair and sharpening of worn milling cutters generally involves two methods: tool grinding and manual sharpening. The former is not a dedicated tool for sharpening milling cutters and requires a professional tool grinder, making the process complex, tedious, and inefficient. The latter involves manual sharpening of the milling cutter on a grinding wheel, where technical issues such as the cutter's geometry and coaxiality are difficult to control, and even a slight mistake can render the cutter unusable.

[0003] Chinese invention patent application number 2019101953356 discloses a milling cutter edge grinding device, including a clamping mechanism and a grinding mechanism. The clamping mechanism includes a rotary table, a mounting block on the rotary table, a milling cutter fixing seat on the mounting block, and a fixing component for clamping the milling cutter on the milling cutter fixing seat. The grinding mechanism includes a cross slide module disposed on one side of the rotary table, a support arm on the cross slide module, a support frame connected to the support arm, a rotary motor fixedly connected to the support frame, and a grinding wheel connected to the rotary motor. The solution provided by the above invention can improve grinding efficiency and accuracy, but the above invention cannot effectively fix the milling cutter when grinding, causing the milling cutter to swing during the grinding process, resulting in deviations in the milling cutter's accuracy.

[0004] Chinese invention patent application number 2021111166636 discloses a multi-station straight shank milling cutter machining center, including a base, a hydraulic indexing rotary table, a robotic arm, a grooving device, a back angle grinding device, and an end-tooth grinding device. The hydraulic indexing rotary table is located in the center of the upper part of the base. The invention has a reasonable and compact structure, inheriting the high efficiency of traditional machine tools and the high precision of modern five-axis tool grinders. Multiple processes are integrated into one machine tool for simultaneous processing, and the efficiency of each machine is significantly improved compared to that of a five-axis tool grinder. However, the invention cannot effectively clean the dust adhering to the milling cutter.

[0005] In existing milling cutter grinding equipment, different grinding parameters are usually set for milling cutters of different sizes. During use, the parameters only need to be adjusted to the required size to grind the milling cutter. However, for milling cutters that break during use, the different locations of the breakage result in different remaining lengths for milling cutters of the same size. Parameter adjustments need to be made for the milling cutter length. Furthermore, in existing technologies, only the bottom of the milling cutter is fixed, which makes the milling cutter prone to shaking during grinding, affecting the grinding accuracy. At the same time, existing technologies lack the ability to detect the wear of the grinding wheel, leading to deviations in milling cutter accuracy that fail to meet usage requirements. Summary of the Invention

[0013] Preferably, the milling cutter clamping assembly further includes a limiting base, the bottom of which is limited by two sets of limiting stops, and the outer side of which is limited by multiple connecting plates. A limiting ring is provided above the limiting base, and the milling cutter body is provided inside the limiting ring.

[0014] Preferably, two sets of limiting strips are provided on one side above the fixing plate, and the two sets of limiting strips are connected in a "+" shape. Each limiting strip has a limiting block on both sides of its end. A pad is provided on the other side above the fixing plate, and a connecting plate is provided on the pad.

[0015] Preferably, each of the limiting grooves is provided with a displacement sensor, which is used to detect the displacement of the sliding block in the limiting groove. The rotating pad is provided with a telescopic component, which is used to control the rotating pad to extend or shorten.

The sliding detection block is disposed in the liquid inlet groove.

[0017] A method for using a milling cutter grinding device for milling mobile phone frames includes the following steps.

[0018] S1. Install the milling cutter body by placing the milling cutter body into the milling cutter clamping assembly, and measure and record the dimensions of the milling cutter body through the milling cutter clamping assembly;

[0019] S2. Grind the top of the milling cutter body flat. By controlling the transmission component, drive the grinding component to move so that the grinding component moves above the milling cutter body and grinds the top of the milling cutter body.

[0020] S3. Sharpen the milling cutter body. Using the dimensions of the milling cutter body measured by the milling cutter clamping assembly, control the transmission assembly to move towards the milling cutter body, and simultaneously adjust the position of the sharpening assembly to sharpen and grind the milling cutter body.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. This invention clamps the top of the milling cutter body by means of a clamping ring set at the top of the connecting rod, and clamps the bottom of the milling cutter body with the sliding block, thereby clamping both the top and bottom ends of the milling cutter body at the same time, which further improves the clamping effect of the milling cutter body. It effectively solves the problem in the prior art that only the bottom of the milling cutter is fixed when fixing the milling cutter, which causes the milling cutter to wobble easily during sharpening and affects the sharpening accuracy of the milling cutter.

[0023] 2. This invention uses coolant in a hollow telescopic tube that contacts the milling cutter body to absorb the heat emitted by the milling cutter body, achieving first-stage heat dissipation. If the milling cutter body continues to heat up, the electrically controlled valve on the hollow telescopic tube is opened, and coolant is continuously supplied to the coolant exchange ring through the coolant inlet pipe. The coolant is then sprayed out through the hollow telescopic tube to achieve second-stage heat dissipation for the milling cutter body, effectively avoiding the problem of excessively high milling cutter body temperature affecting the grinding accuracy.

[0024] 3. This invention connects the fluid exchange ring to the coolant inlet pipe via an inlet groove, and simultaneously places a sliding detection block inside the inlet groove. By controlling the contact between the conical grinding wheel and the sliding detection block, the wear condition of the conical grinding wheel is detected, and the iron filings adsorbed on the conical grinding wheel are effectively cleaned. The pressure value detected by the hydraulic sensor inside the fluid exchange ring is used to detect the condition of the milling cutter body during the grinding process, and the feed rate of the conical grinding wheel is adjusted synchronously. This effectively avoids the problem of excessive single grinding feed rate of the conical grinding wheel causing severe vibration of the milling cutter body and secondary breakage of the conical grinding wheel.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1

[0035] like Figures 1 to 7 As shown, a milling cutter grinding device for milling the frame of a mobile phone includes a fixing component 1, a milling cutter clamping component 2 is provided on one side above the fixing component 1, a transmission component 3 is provided on the other side above the fixing component 1, a grinding component 4 is provided on the transmission component 3, and a milling cutter body 5 is provided inside the milling cutter clamping component 2.

[0036] The fixing component 1 includes a fixing plate 101. Multiple sets of connectors 102 are arranged in a linear array on both sides of the fixing plate 101. The connectors 102 are connected to the fixing plate 101 by bolts, and a connecting screw is provided at the end of the connector 102 away from the fixing plate 101. The connecting screw is used to fix the fixing plate 101. By setting multiple sets of connectors 102 on both sides of the fixing plate 101 and providing a connecting screw on each connector 102, the device can be fixed to the workbench by the connecting screw, thereby preventing the device from moving during use. At the same time, the setting of the connecting screw makes the device easy to disassemble and fix, improving the applicability of the device.

[0037] Two sets of limiting bars 103 are provided on one side of the upper part of the fixed plate 101, and the two sets of limiting bars 103 are connected in a "+" shape. Each limiting bar 103 has a limiting block 104 on both sides of its end. A pad 105 is provided on the other side of the upper part of the fixed plate 101, and a connecting plate 106 is provided on the pad 105. By setting two sets of limiting bars 103 connected in a "+" shape on the fixed plate 101, the milling cutter clamping assembly 2 is fixed, thereby improving the stability of the milling cutter clamping assembly 2. By setting the limiting block 104 on each limiting bar 103, the stability of the milling cutter clamping assembly 2 is further improved under the double limiting of the limiting bar 103 and the limiting block 104, so as to avoid the problem of the milling cutter clamping assembly 2 shaking during the milling cutter sharpening process, which affects the sharpening accuracy.

[0038] The milling cutter clamping assembly 2 includes a limiting base 201. The bottom of the limiting base 201 is connected to two sets of limiting stops 103, and the outer side of the limiting base 201 is connected to multiple connecting plates 106. A limiting ring 202 is provided above the limiting base 201, and the milling cutter body 5 is provided inside the limiting ring 202. By setting the limiting base 201, the inside of the limiting base 201 is connected to the limiting stops 103, and the outside is connected to the connecting plates 106, thereby achieving double fixation of the limiting base 201, improving the stability of the milling cutter clamping assembly 2 and avoiding the problem of shaking affecting the cutting accuracy during the milling cutter sharpening process.

[0039] The milling cutter clamping assembly 2 also includes a limiting ring 202. The limiting ring 202 has a limiting groove 203 inside. A telescopic spring 204 is provided on one side of the limiting groove 203. A sliding block 205 is connected to one end of the telescopic spring 204 near the milling cutter body 5. A pressure sensor is provided at one end of the sliding block 205 near the milling cutter body 5. The pressure sensor is used to detect the pressure value of the sliding block 205 on the milling cutter body 5. The top of the sliding block 205 is composed of multiple sets of conical structures. Multiple sets of connecting grooves are arranged in a ring array above the limiting groove 203. A connecting rod 206 is provided in the connecting groove. The bottom of the connecting rod 206 is provided with a protrusion that matches the conical structure at the top of the sliding block 205. A clamping ring 207 is provided at the top of the connecting rod 206. By setting the limiting ring 202 on the limiting base 201 and setting the milling cutter body 5 in the limiting ring 202, and a displacement sensor is provided in each limiting groove 203, the displacement sensor is used to detect the displacement of the sliding block 205 in the limiting groove 203.

[0040] The double limiting of the limiting base 201 by the fixing component 1 improves the fixing effect of the limiting ring 202 on the milling cutter body 5. At the same time, by setting the telescopic spring 204 and the sliding block 205 in the limiting ring 202, when the milling cutter body 5 is placed in the limiting ring 202, the telescopic spring 204 will push the sliding block 205 to move towards the milling cutter body 5 and fix and support the bottom of the milling cutter body 5. Meanwhile, the pressure value detected by the pressure sensor determines whether the sliding block 205 is effectively supporting and fixing the milling cutter body 5. When the pressure value detected by the pressure sensor is within the preset range, it means that the sliding block 205 is in contact and pressing with the milling cutter body 5. At this time, the displacement sensor records the displacement of the sliding block 205, and the diameter of the milling cutter body 5 is obtained from the displacement of the sliding block 205. Thus, the grinding component 4 adjusts the corresponding parameters according to the measured diameter of the milling cutter body 5, which effectively improves the detection accuracy, reduces the workload of workers, and improves the grinding efficiency of the device.

[0041] Furthermore, the top of the milling cutter body 5 is clamped by the clamping ring 207 set at the top of the connecting rod 206, and the bottom of the milling cutter body 5 is clamped by the sliding block 205. Thus, both the top and bottom ends of the milling cutter body 5 are clamped at the same time, which further improves the clamping effect of the milling cutter body 5. This effectively solves the problem in the prior art where only the bottom of the milling cutter is fixed when fixing the milling cutter, which causes the milling cutter to wobble easily during sharpening and affects the sharpening accuracy of the milling cutter.

[0042] The transmission assembly 3 includes a transmission housing 301. A telescopic support leg 302 is provided at the bottom of the transmission housing 301. A transmission cavity 303 is provided on the side of the transmission housing 301 near the milling cutter clamping assembly 2. A drive motor 304 is provided on the side of the transmission cavity 303 away from the transmission housing 301. A transmission roller is provided on the output shaft of the drive motor 304, and the transmission roller passes through the transmission cavity 303 and extends into the transmission housing 301. A transmission block 305 is provided on the drive roller. By providing a telescopic support leg 302 at the bottom of the transmission housing 301, the transmission assembly 3 is effectively supported, avoiding the problem of shaking when the milling cutter body 5 is sharpened due to lack of support at the bottom of the transmission assembly 3, which would affect the sharpening accuracy of the milling cutter body 5. At the same time, the drive motor 304 on the transmission housing 301 drives the transmission block 305 to slide within the transmission housing 301, thereby causing the sharpening assembly 4 to move laterally toward the milling cutter body 5, realizing the sharpening process of the milling cutter body 5.

[0043] The grinding assembly 4 includes a rotating pad 401, the bottom of which is connected to a transmission block 305. A slide plate 402 is located above the rotating pad 401, and a motor support 403 is located on one side above the slide plate 402. A rotary motor 404 is located above the motor support 403. A grinding wheel motor 405 is connected to the output shaft of the rotary motor 404. The rotary motor 404 is used to control the rotation of the grinding wheel motor 405. By connecting the rotating pad 401 to the transmission block 305 and adjusting the distance and angle between the grinding assembly 4 and the milling cutter body 5 in coordination with the movement of the transmission block 305, the grinding angle of the milling cutter body 5 can be adjusted. At the same time, the rotary motor 404 drives the grinding wheel motor 405 to rotate, adjusting the tilt angle of the grinding assembly 4, thereby achieving precise control of the milling cutter body 5 according to the sharpening requirements of different milling cutters.

[0044] A support plate 406 is provided at the center of the upper part of the slide plate 402. The output shaft of the rotary motor 404 passes through the support plate 406. A telescopic rod 407 is provided on the grinding wheel motor 405. A conical grinding wheel 408 is connected to one end of the telescopic rod 407 near the transmission component 3. The conical grinding wheel 408 is used to sharpen the milling cutter body 5. The telescopic rod 407 is used to control the movement of the conical grinding wheel 408 toward the milling cutter body 5. By setting the telescopic rod 407 on the grinding wheel motor 405 and the conical grinding wheel 408 on the telescopic rod 407, the movement of the conical grinding wheel 408 toward the milling cutter body 5 is controlled by the telescopic rod 407, thereby realizing the control of the conical grinding wheel 408 to complete the sharpening process of the milling cutter body 5.

[0045] In use, the milling cutter body 5 is placed inside the limiting ring 202. At the same time, the movement and extrusion force of the sliding block 205 are detected by the pressure sensor and displacement sensor to obtain the diameter of the milling cutter body 5. Meanwhile, the upper part of the milling cutter body 5 is clamped by the clamping ring 207 to complete the clamping and fixing of the milling cutter body 5. Then, the drive motor 304 is controlled to drive the transmission block 305 to move in the direction of the milling cutter body 5, and the grinding wheel motor 405 drives the conical grinding wheel 408 to rotate. At the same time, the rotary motor 404 and the rotating pad 401 adjust the cutting angle and tilt angle of the conical grinding wheel 408, and the grinding process of the conical grinding wheel 408 is completed by the extension and retraction of the telescopic rod 407.

[0046] Example 2

[0047] A method for using a milling cutter grinding device for milling mobile phone frames includes the following steps:

[0048] S1. Install the milling cutter body 5 by placing it into the milling cutter clamping assembly 2, and measure and record the dimensions of the milling cutter body 5 through the milling cutter clamping assembly 2.

[0049] S2. Grind the top of the milling cutter body 5 flat. Control the transmission component 3 to drive the grinding component 4 to move so that the grinding component 4 moves above the milling cutter body 5 and grinds the top of the milling cutter body 5.

[0050] S3. Sharpen the milling cutter body 5. Using the dimensions of the milling cutter body 5 measured by the milling cutter clamping assembly 2, control the transmission assembly 3 to move towards the milling cutter body 5. At the same time, adjust the position of the sharpening assembly 4 to sharpen and grind the milling cutter body 5.

[0051] Example 3

[0052] In actual use, operators found that the conical grinding wheel 408 wears down after prolonged use, resulting in a significant deviation between the accuracy of the milling cutter body 5 and the preset grinding parameters, rendering it unusable. Furthermore, the conical grinding wheel 408 easily attracts iron filings, affecting grinding accuracy. Additionally, existing technologies for milling cutters that break during use suffer from varying fracture locations, leading to different lengths of cutters of the same size remaining, and consequently, different actual heights for cutters of the same diameter. This makes it impossible to effectively grind the cutters according to preset parameters. Therefore, to solve these technical problems, the device is improved according to the method described in this embodiment.

[0053] A detection groove 208 is provided on the clamping ring 207, and a sliding detection block 209 is provided in the detection groove 208. A fluid exchange ring 210 is provided inside the clamping ring 207, and multiple hollow telescopic tubes 211 are arrayed on the fluid exchange ring 210. A hydraulic sensor is provided inside the fluid exchange ring 210 to detect the hydraulic value inside the fluid exchange ring 210. An electrically controlled valve is provided at one end of the hollow telescopic tube 211 near the end of the milling cutter body 5. The electrically controlled valve is used to control the connection and closure of the hollow telescopic tube 211 with the outside. A liquid inlet groove is provided inside the clamping ring 207, and one end of the liquid inlet groove is connected to the coolant inlet pipe, and the other end is connected to the fluid exchange ring 210. The sliding detection block 209 is set in the liquid inlet groove.

[0054] First, when it is necessary to detect the height and diameter of the milling cutter body 5, the clamping ring 207 is pulled upwards, causing the connecting rod 206 to separate from the sliding block 205. At this time, the connecting rod 206 will no longer limit the sliding block 205. Under the elastic force of the telescopic spring 204, the sliding block 205 will be pushed towards the milling cutter body 5. The movement of the sliding block 205 is detected by the pressure sensor and displacement sensor, and the diameter of the milling cutter body 5 is obtained. During this process, when the clamping ring 207 moves upwards, the hollow telescopic tube 211 set in the clamping ring 207 will contact the circumferential side of the milling cutter body 5 and slide on the circumferential side of the milling cutter body 5, so that the liquid in the fluid changing ring 210... When the pressure value fluctuates, and the fluid exchange ring 210 moves above the cutter body 5, the hollow telescopic tube 211 will no longer be in contact with the cutter body 5. At this time, the hydraulic value detected by the hydraulic sensor will return to the initial state. The length of the cutter body 5 is obtained by measuring the hydraulic change detected by the hydraulic sensor and the movement of the clamping ring 207. Based on the obtained length and diameter of the cutter body 5, the grinding parameters of the grinding assembly 4 are adjusted accordingly, thereby realizing automated grinding. This effectively solves the problem in the prior art that for cutters that break during use, the lengths of cutters of the same size that are retained are different due to the different locations of the breakage, resulting in different actual heights of cutters of the same diameter, making it impossible to effectively grind the cutters according to preset parameters.

[0055] Secondly, when the conical grinding wheel 408 needs to be inspected, the transmission assembly 3 controls the conical grinding wheel 408 to move towards the milling cutter body 5. During this process, the conical grinding wheel 408 will first contact the inspection groove 208 and press the sliding inspection block 209 set in the inspection groove 208. At this time, the grinding wheel motor 405 drives the conical grinding wheel 408 to rotate slowly, so that the conical grinding wheel 408 continuously presses the sliding inspection block 209. Since the sliding inspection block 209 is set in the liquid inlet groove, and the liquid inlet groove is connected to the liquid exchange ring 210, the hydraulic pressure value in the liquid exchange ring 210 will continuously change with the rotation of the conical grinding wheel 408. By detecting the amplitude of the hydraulic pressure change in the liquid exchange ring 210, the conical grinding wheel 408 can be inspected. The wear condition of the conical grinding wheel 408 is judged. If the hydraulic change amplitude is within the preset range, it means that the conical grinding wheel 408 is in normal condition. If the hydraulic change amplitude exceeds the preset range, it means that the conical grinding wheel 408 is severely worn and cannot accurately grind the milling cutter body 5. The rotating conical grinding wheel 408 drives the sliding detection block 209 to reciprocate, thereby achieving accurate detection of the wear condition of the conical grinding wheel 408. This effectively avoids the problem that the conical grinding wheel 408 will wear itself after long-term use, resulting in a large deviation between the accuracy of the milling cutter body 5 and the preset accuracy when grinding the milling cutter body 5 according to the preset grinding parameters, making it unusable.

[0056] Secondly, when the upper and lower ends of the milling cutter body 5 need to be clamped, by pressing down the pulled-up clamping ring 207, the bottom of the connecting rod 206 engages with the top of the sliding block 205 again, thereby limiting the sliding block 205 and keeping its position unchanged during the grinding process, providing effective support for the milling cutter body 5. At this time, as the clamping ring 207 moves downward, the conical grinding wheel 408 separates from the sliding detection block 209. Without the pressure of the conical grinding wheel 408, the sliding detection block 209 is pushed outward by the hydraulic pressure of the coolant in the fluid exchange ring 210, thus connecting the coolant inlet pipe to the fluid exchange ring 210 through the inlet groove. A large amount of cooling water is then introduced into the fluid exchange ring 210 through the coolant inlet pipe, causing the multiple hollow telescopic tubes 211 connected to the fluid exchange ring 210 to extend and engage the milling cutter body 5. The upper part of the cutter body 5 is fixed, and the upper and lower ends of the cutter body 5 are double-clamped to improve the stability of the cutter body 5 during the grinding process and avoid the problem of the cutter body 5 shaking. At the same time, during the grinding process of the grinding assembly 4, the temperature of the cutter body 5 will gradually rise under the grinding of the conical grinding wheel 408. At this time, the coolant in the hollow telescopic tube 211 that is in contact with the cutter body 5 absorbs the heat emitted by the cutter body 5, realizing the first-stage heat dissipation of the cutter body 5. If the temperature of the cutter body 5 continues to rise, the electronically controlled valve on the hollow telescopic tube 211 is opened and the coolant inlet pipe continuously supplies coolant into the coolant exchange ring 210 and sprays the coolant out through the hollow telescopic tube 211 to achieve the second-stage heat dissipation of the cutter body 5. This effectively avoids the problem of the cutter body 5 being too hot and affecting the grinding accuracy.

[0057] Finally, during the grinding process of the milling cutter body 5, the hydraulic value in the fluid changing ring 210 is detected in real time by a hydraulic sensor installed in the fluid changing ring 210. If the fluctuation of the hydraulic value in the fluid changing ring 210 is within the preset range, it means that the grinding feed of the conical grinding wheel 408 is within the normal range. If the fluctuation of the hydraulic value in the fluid changing ring 210 is greater than the preset range, it means that the single grinding feed of the conical grinding wheel 408 is too large, causing severe vibration of the milling cutter body 5. At this time, the single grinding feed is adjusted by controlling the grinding component 4, so that the conical grinding wheel 408 can perform different feeds according to the milling cutter body 5 of different materials, further improving the grinding effect of the device and effectively avoiding the problem of secondary breakage of the milling cutter body 5 due to excessive feed.

[0058] It should be noted that this invention connects the fluid exchange ring 210 to the coolant inlet pipe via the inlet groove, and simultaneously places the sliding detection block 209 inside the inlet groove. By controlling the contact between the conical grinding wheel 408 and the sliding detection block 209, the wear condition of the conical grinding wheel 408 is detected, and the iron filings adsorbed on the conical grinding wheel 408 are effectively cleaned. The pressure value detected by the hydraulic sensor inside the fluid exchange ring 210 is used to detect the condition of the milling cutter body 5 during the grinding process, and the feed rate of the conical grinding wheel 408 is adjusted synchronously. This effectively avoids the problem of the milling cutter body 5 being severely vibrated and the conical grinding wheel 408 breaking down twice due to excessive single grinding feed of the conical grinding wheel 408.
