Description

Technical Field

[0001] The present invention relates to the technical field of grinding, and particularly relates to a profiling grinding device for glass covers. Background Art

[0002] In the prior art, a numerical control milling machine is generally used to machine the large surface of a glass cover and the boss on the glass cover. However, this machining method is likely to leave tool marks on the machined surface of the glass cover, affecting the surface quality of the glass cover, and the machining efficiency is relatively low. In addition, due to the high cost of the numerical control milling machine, the manufacturing and processing cost of the glass cover is also increased. Summary of the Invention

[0003] To solve the technical problems in the background art, the present invention proposes a profiling grinding device for glass covers.

[0004] The profiling grinding device for glass covers includes: a grinding wheel, a first motor, a follower wheel, a feeding mechanism, a glass cover fixing seat, a second motor, a transmission mechanism, and a profiling template. The grinding wheel and the follower wheel have the same diameter and are coaxially and fixedly connected to a first rotating shaft. The top end of the feeding mechanism is rotationally connected to the grinding wheel and the follower wheel. One end of the first rotating shaft is connected to the output shaft of the first motor. The input end of the transmission mechanism is connected to the output shaft of the second motor. The first output end of the transmission mechanism is connected to the rotating shaft of the glass cover fixing seat. The second output end of the transmission mechanism is connected to the rotating shaft of the profiling template. The rotating shafts of the glass cover fixing seat and the profiling template are coaxially arranged and have the same rotational speed. The outer peripheral contour of the profiling template is the same as the outer peripheral contour of the boss of the glass cover fixed on the glass cover fixing seat. The rotating shaft of the glass cover fixing seat is arranged parallel to the first rotating shaft. When the grinding wheel grinds to a certain position of the outer peripheral contour of the boss of the glass cover under the drive of the feeding mechanism, the follower wheel will also touch the corresponding outer peripheral contour on the profiling template at the position where the boss is ground.

[0005] Preferably, the input end of the transmission mechanism includes a first gear, a second gear, and a second rotating shaft with the same shape. The first gear and the second gear are coaxially fixed on the second rotating shaft. One end of the second rotating shaft is connected to the output shaft of the second motor. The first output end of the transmission mechanism includes a third gear. The third gear is sleeved and fixed on the rotating shaft of the glass cover fixing seat and meshes with the first gear. The second output end of the transmission mechanism includes a fourth gear with the same shape as the third gear. The fourth gear is sleeved and fixed on the rotating shaft of the profiling template and meshes with the second gear.

[0006] Preferably, the first gear, the second gear, the third gear, and the fourth gear are all gears with the same shape.

[0007] Preferably, an arc chamfer identical to the fillet contour at the bottom of the boss of the glass cover is machined at the outer edge of the grinding wheel.

[0008] Preferably, the feeding mechanism includes a sliding table, a base with a chute formed in its top wall, a fixed seat, and a tension spring. The first rotating shaft is rotatably connected to the top of the sliding table, and the bottom of the sliding table can slide in the chute of the base. The sliding direction of the sliding table is a horizontal direction parallel to the grinding surface of the glass cover plate. One end of the tension spring is fixedly connected to the sliding table, and the other end is fixedly connected to the fixed seat. The tension spring and the fixed seat are located in the sliding direction of the sliding table. The pulling force of the tension spring can press the grinding wheel against the grinding position of the glass cover plate. At the same time, when the contact wheel touches the profiling template, the profiling template can bounce the contact wheel away.

[0009] Preferably, the feeding mechanism further includes a limiting component. The limiting component includes a first limiting rod and a second limiting rod arranged horizontally and coaxially. One end of the first limiting rod is fixedly connected to the sliding table, and one end of the second limiting rod is fixedly connected to the fixed seat. When the contact wheel touches the profiling template, the end face of the first limiting rod away from the sliding table will abut against the end face of the second limiting rod away from the fixed seat.

[0010] Preferably, the glass cover plate fixing seat includes a glass cover plate fixing seat body, a plate body, and an air extraction pipeline. The bottom wall of the plate body is fixedly installed on the glass cover plate fixing body. Through holes are formed in the plate body, penetrating the bottom wall and the top wall of the plate body. The through holes are communicated with one end of the air extraction pipeline, and the other end of the air extraction pipeline is communicated with a vacuum generator. The glass cover plate can be adsorbed on the top wall of the plate body.

[0011] Preferably, a positioning groove adapted to the glass cover plate is further formed on the top wall of the plate body, and the bottom of the glass cover plate opposite to the convex platform can be placed therein. The position of the positioning groove should correspond to the position of the profiling template, and the through hole is located at the center of the positioning groove.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] When machining the large surface of the glass cover plate by using the grinding method of the grinding wheel, compared with the prior art using a numerical control milling machine for machining, a higher-quality surface that is smoother and has no residual tool marks can be obtained, and the machining efficiency is higher. By using the profiling template to limit the grinding position of the grinding wheel, the convex platform of the glass cover plate can be machined reliably and conveniently, further improving the machining efficiency. In addition, the profiling grinding device for the glass cover plate in the present invention has a relatively simple structure and only requires a low manufacturing cost, thereby reducing the machining cost of the glass cover plate.

[0014] An arc chamfer identical to the rounded corner profile at the bottom of the convex platform of the glass cover plate is machined at the outer edge of the grinding wheel, which can further completely and efficiently machine the convex platform profile.

[0015] The feeding mechanism with a tension spring enables the feeding mechanism to have a reliable function of self-adjusting the feeding amount, improving the working reliability of the device. Description of the Drawings

[0021] The following will describe in detail the specific implementation manners of the present invention with reference to the accompanying drawings.

[0022] Refer to Figures 1 to 5 , a glass cover plate profiling grinding device, comprising: a grinding wheel 1, a first motor, a follower wheel 2, a feed mechanism, a glass cover plate fixing seat 4, a second motor, a transmission mechanism, and a template 3. The grinding wheel 1 and the follower wheel 2 have the same diameter and are coaxially and fixedly connected to a first rotating shaft 19. The top of the feed mechanism is rotationally connected to the grinding wheel 1 and the follower wheel 2. One end of the first rotating shaft 19 is connected to the output shaft of the first motor. The input end of the transmission mechanism is connected to the output shaft of the second motor. The first output end of the transmission mechanism is connected to the rotating shaft of the glass cover plate fixing seat 4. The second output end of the transmission mechanism is connected to the rotating shaft of the template 3. The rotating shafts of the glass cover plate fixing seat 4 and the template 3 are coaxially arranged and have the same rotational speed. The outer peripheral contour of the template 3 is the same as the outer peripheral contour of the convex platform 51 of the glass cover plate 5 fixed on the glass cover plate fixing seat 4. The rotating shaft of the glass cover plate fixing seat 4 is arranged parallel to the first rotating shaft 19. When the grinding wheel 1 grinds to a certain position of the outer peripheral contour of the convex platform 51 of the glass cover plate under the drive of the feed mechanism 1, the follower wheel 2 will also touch the corresponding position on the outer peripheral contour of the template 3 where the convex platform 51 is being ground.

[0023] The working principle of the glass cover plate profiling grinding device is as follows: First, fix the glass cover plate 5 to be ground on the glass cover plate fixing seat 2. When fixing, pay attention to the positional relationship corresponding to the template 3. Subsequently, move the moving feed mechanism. After the grinding wheel 1 contacts the glass cover plate 5, start the first motor to make the grinding wheel 1 rotate to start grinding. At the same time, the second motor can also be started to make the glass cover plate 5 and the template 3 rotate synchronously. When the grinding wheel 1 grinds to the contour of the boss 51 of the glass cover plate, the follower wheel 2 will also touch the outer peripheral contour of the template 3 corresponding to the position where the boss 51 is ground. The grinding wheel 1 stops further feeding and grinding at this contour, thereby machining the accurate contour shape of the boss 51.

[0024] By using the grinding wheel 1 to grind the large surface of the glass cover plate 5, compared with the existing technology of using a CNC milling machine for processing, a smoother surface without knife mark residues can be obtained, and the processing efficiency is higher. Using the template 3 to limit the grinding position of the grinding wheel 1, the boss 51 of the glass cover plate can be machined reliably and conveniently, further improving the processing efficiency. In addition, the structure of the glass cover plate profiling grinding device in the present invention is relatively simple and only requires a low manufacturing cost, thereby reducing the processing cost of the glass cover plate 5.

[0025] The input end of the transmission mechanism includes a first gear 6, a second gear 7, and a second rotating shaft 8 with the same outer shape. The first gear 6 and the second gear 7 are coaxially fixed on the second rotating shaft 8. One end of the second rotating shaft 8 is connected to the output shaft of the second motor. The first output end of the transmission mechanism includes a third gear 9. The third gear 9 is sleeved and fixed on the rotating shaft of the glass cover plate fixing seat 4 and meshes with the first gear 6. The second output end of the transmission mechanism includes a fourth gear 10 with the same outer shape as the third gear 9. The fourth gear 10 is sleeved and fixed on the rotating shaft of the template 3 and meshes with the second gear 7. This transmission mechanism structure is relatively simple and compact, and has a reliable transmission ratio, which can effectively ensure that the rotating shafts of the glass cover plate fixing seat 4 and the template 3 have the same rotational speed.

[0026] The first gear 6, the second gear 7, the third gear 9, and the fourth gear 10 are all gears with the same outer shape to reduce the workload and difficulty of design, processing, and assembly.

[0027] Refer to Figure 2 In order to further completely and efficiently machine the contour of the boss 51, an arc chamfer 1a identical to the rounded corner 511 contour at the bottom of the boss of the glass cover plate is machined at the outer edge of the grinding wheel 1.

[0028] Refer to Figure 3, the feeding mechanism of the glass cover plate profiling grinding device includes a sliding table 11, a base 12 with a chute opened on its top wall, a fixed seat 13, and a tension spring 14. The top of the sliding table 11 is rotatably connected to a first rotating shaft 19. The bottom of the sliding table 11 can slide in the chute 121 of the base 12. The sliding direction of the sliding table 11 is the horizontal direction parallel to the surface to be ground of the glass cover plate 5. One end of the tension spring 14 is fixedly connected to the sliding table 11, and the other end is fixedly connected to the fixed seat 13. The tension spring 14 and the fixed seat 13 are located in the sliding direction of the sliding table 11. The pulling force of the tension spring 14 can make the grinding wheel 1 press against the area to be ground of the glass cover plate. At the same time, when the follower wheel 2 touches the profiling die 3, the profiling die 3 can bounce the follower wheel 2 away.

[0029] The tension spring 14 can not only enable the grinding wheel 1 to perform grinding reliably, but also bounce the grinding wheel 1 away from the grinding area of the boss 51 of the glass cover plate when the follower wheel 2 touches the profiling die 3, that is, when the grinding wheel 1 grinds to the contour of the boss 51 of the glass cover plate. After the glass cover plate 5 rotates to a new position driven by the glass cover plate fixing seat 4, the grinding wheel 1 will be pulled back by the pulling force of the tension spring 14 and re-pressed against the position to be ground on the glass cover plate 5 for grinding. This process is repeated until the contour of the boss 51 of the glass cover plate is completely ground.

[0030] The feeding mechanism with the tension spring 14 enables the feeding mechanism to have a reliable function of self-adjusting the feeding amount, improving the working reliability of the device.

[0031] Refer to Figure 3 , the feeding mechanism further includes a limiting component. The limiting component includes a first limiting rod 15 and a second limiting rod 16 arranged horizontally and coaxially. One end of the first limiting rod 15 is fixedly connected to the sliding table 11, and one end of the second limiting rod 16 is fixedly connected to the fixed seat 13. When the follower wheel 2 touches the profiling die 3, the end face of the first limiting rod 15 away from the sliding table 11 will abut against the end face of the second limiting rod 16 away from the fixed seat 13.

[0032] The limiting component can further ensure that the grinding wheel 1 will not continue to feed and grind when grinding to the contour of the boss 51 of the glass cover plate, improving the working reliability of the device. In practical applications, the first limiting rod 15 can be designed as a telescopic rod to adjust different limiting positions according to different contour positions.

[0033] Refer to Figure 5 , the glass cover plate fixing seat 4 includes a glass cover plate fixing seat body 41, a plate body 17, and an air extraction pipeline 18. The bottom wall of the plate body 17 is fixedly installed on the glass cover plate fixing body. A through hole 171 penetrating the bottom wall and the top wall of the plate body 17 is opened on the plate body 17. The through hole 171 is communicated with one end of the air extraction pipeline 18, and the other end of the air extraction pipeline 18 is communicated with a vacuum generator. The glass cover plate 5 can be negatively pressure adsorbed on the top wall of the plate body 17. Refer to Figure 5, in this embodiment, in order to ensure the adsorption effect, a number of flow channels 173 communicating with the through holes 171 are also provided to form a relatively comprehensive adsorption force on the glass cover plate 5. Compared with the traditional clamping tooling, using vacuum adsorption fixation can protect the surface of the glass cover plate from being scratched.

[0034] A positioning groove 172 adapted to the glass cover plate 5 is also provided on the top wall of the plate body 17, into which the bottom of the glass cover plate 5 opposite to the convex platform 51 can be placed. The position of the positioning groove 172 should correspond to the position of the template 3. The through hole 171 is located at the central part of the positioning groove 172. The positioning groove 172 can ensure that the glass cover plate 5 is quickly and accurately fixed and positioned on the glass cover plate fixing seat 4.

[0035] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
