[0002] In existing technologies, when adjusting the position of the grinding head assembly of a glass edging machine, only the entire grinding head assembly can be moved and adjusted. However, for cases where the same grinding head assembly has a coaxial dual-grinding head structure, the traditional structure of moving the entire grinding head assembly is obviously not suitable for the independent movement and adjustment of a single grinding head. For example, the invention patent with patent number 202122481339.6 discloses an automatic feeding device for polishing grinding heads. The automatic feeding device for polishing grinding heads includes a lead screw, a first motor, and an adjustment mechanism. The lead screw is equipped with a driven gear, the first motor is equipped with a drive gear, and the adjustment mechanism is equipped with a manual gear. The driven gear meshes with the drive gear and the manual gear respectively. This kind of automatic feeding device for polishing grinding heads is used for the movement and adjustment of the entire grinding head assembly, but it is not suitable for the independent movement and adjustment of a single grinding head in a coaxial dual-grinding head structure, and has certain limitations.

[0028] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] like Figure 1-5 As shown, this dual-grinding-head electric adjustment assembly can be applied to glass edging machines for glass grinding. It includes a base 1, an outer grinding head 2 and an inner grinding head 3 both mounted on the base 1, and a grinding head drive device 4 for rotating the outer grinding head 2 and the inner grinding head 3. The outer grinding head 2 and the inner grinding head 3 can be of different grinding precision to adapt to different processing needs or to grind different positions. The inner grinding head 3 is located inside the outer grinding head 2 and is coaxially arranged with it. This coaxial arrangement of the inner grinding head 3 and the outer grinding head 2 facilitates the miniaturization of the dual-grinding-head electric adjustment assembly. The coaxial arrangement of the grinding head 2 also facilitates different grinding processes on the glass. The base 1 is equipped with a central shaft 5 fixed to the inner grinding head 3 and an electric adjustment device 6 for adjusting the position of the inner grinding head 3. The electric adjustment device 6 is electrically connected to the control device of the glass edging machine. The electric adjustment device 6 is configured to cooperate with the central shaft 5 to drive the central shaft 5 to move axially, so that the inner grinding head 3 can be adjusted in axial position relative to the outer grinding head 2. The inner grinding head 3 can be adjusted in axial position according to actual processing requirements. The use of the electric adjustment device 6 facilitates the rapid adjustment of the inner grinding head 3, which is beneficial to the processing efficiency of the glass edging machine.

[0030] In some embodiments of the present invention, such as Figure 1-4 As shown, the electric adjustment device 6 includes a rod 61 that cooperates with the central shaft 5 and a driver 62 connected to the rod 61 and used to drive the rod 61 to move axially along the central shaft 5. When the rod 61 is running, it drives the central shaft 5 to move.

[0031] In some embodiments of the present invention, such as Figure 1-4As shown, when the driver 62 drives the rod 61 to run, the rod 61 moves the central shaft 5 by pushing. The pushing method is beneficial to the stable movement of the central shaft 5. The driver 62 is a first motor assembly, and the rod 61 is a first screw. The output end of the first motor assembly is connected to the first screw. The end of the rod 61 facing the central shaft 5 is provided with a spherical part 7 for the rod 61 to push the central shaft 5. The surface of the spherical part 7 has a mating surface for forming spherical contact. The rod 61 and the spherical part 7 make spherical contact. The spherical contact is a point contact, which has low friction. When the driver 62 drives the rod 61, which is the first screw, to rotate, the setting of the spherical part 7 reduces the frictional resistance of the rod 61 during rotation. The spherical part 7 is a steel ball. Steel balls have low procurement costs and simple structure, which can achieve the effect of reducing the frictional resistance of the rod 61 during rotation.

[0032] In some embodiments of the present invention, such as Figure 1 , 2 As shown in Figure 4, a transmission seat 8 is provided between the rod 61 and the central shaft 5. The rod 61 pushes the central shaft 5 through the transmission seat 8, and the rod 61 indirectly pushes the central shaft 5. The spherical part 7 is located between the rod 61 and the transmission seat 8. The rod 61 pushes the transmission seat 8 through the spherical part 7. The rod 61 and the transmission seat 8 are respectively provided with grooves for cooperating with the spherical part 7. The grooves are used to accommodate the spherical part 7. The spherical part 7 makes spherical contact with the rod 61 and the transmission seat 8 respectively. The spherical contact also helps to limit the shaking of the transmission seat 8 and the rod 61 during operation and improves stability.

[0033] In some embodiments of the present invention, such as Figure 1 , 2 As shown in Figure 4, the electric adjustment device 6 includes an elastic element 62. The elastic element 62 is connected to the central shaft 5 and is used for the retraction and reset of the central shaft 5 and the inner grinding head 3. In this embodiment, the direction of the rod 61 toward the outer grinding head 2 and the inner grinding head 3 is positive, and the direction of the rod 61 away from the outer grinding head 2 and the inner grinding head 3 is negative. When the driver 62 drives the rod 61 to move positively, the central shaft 5 and the inner grinding head 3 move positively for adjustment, and the inner grinding head 3 moves in the direction of extending out of the outer grinding head 2. When the driver 62 drives the rod 61 to move negatively, the elastic element 62 drives the central shaft 5 and the inner grinding head 3 to move negatively for reset, and the inner grinding head 3 moves in the direction of retracting into the outer grinding head 2. The elastic element 62 is a spring. The spring structure is simple and easy to set. The elastic element 62 and the driver 62 cooperate to realize the positive and negative movement adjustment of the inner grinding head 3.

The first positioning seat 11 and the second positioning seat 12 are spaced apart. An elastic member 62 is fitted on the central shaft 5, and the two ends of the elastic member 62 contact the first positioning seat 11 and the second positioning seat 12 respectively, so as to realize the positioning of the elastic member 62.

[0035] The first positioning seat 11 is fixed on the central shaft 5 and rotates synchronously with the central shaft 5. A first bearing 13 is fitted on the outer side of the first positioning seat 11. The transmission seat 8 abuts against the end of the first bearing 13. The arrangement of the first bearing 13 ensures that the rotation of the central shaft 5 is not affected by the push of the transmission seat 8. The second positioning seat 12 rotates synchronously with the central shaft 5. One of the sides of the central shaft 5 and the inner side of the second positioning seat 12 is provided with a positioning groove extending along the axial direction. The other side of the central shaft 5 and the inner side of the second positioning seat 12 is provided with a limiting block (such as a spline groove structure) that cooperates with the positioning groove, so that the second positioning seat 12 can rotate synchronously with the central shaft 5 without affecting the axial movement of the central shaft 5.

[0036] In some embodiments of the present invention, such as Figure 1 , 2 As shown in Figure 4, the transmission seat 8 includes a guide sleeve 81 and a pressure sleeve 82 mounted on the guide sleeve 81 by fasteners. The pressure sleeve 82 is embedded in the guide sleeve 81, and one end of the pressure sleeve 82 extends out of the guide sleeve 81 toward the central shaft 5. The pressure sleeve 82 abuts against the end of the first bearing 13. The spherical part 7 is located between the rod 61 and the guide sleeve 81. The pressure sleeve 82 is used to cooperate with the first bearing 13, and the guide sleeve 81 is used to cooperate with the spherical part 7.

[0037] The end of the central shaft 5 is provided with an end cap 14 that is installed by fasteners. The end cap 14 presses the first bearing 13 tightly onto the first positioning seat 11 and presses the first positioning seat 11 tightly onto the central shaft 5. The central shaft 5 is provided with a stepped portion that abuts against the first positioning seat 11 to achieve positioning of the first positioning seat 11 and the first bearing 13. The end cap 14 is located inside the pressure sleeve 82 and does not affect the pressure sleeve 82.

[0038] A sleeve 15 is provided on the base 1, and the sleeve 15 is located on the side of the base 1 away from the inner grinding head 3. The driver 62 is provided on the sleeve 15. In this embodiment, the side of the outer grinding head 2 and the inner grinding head 3 is the front part of the dual grinding head electric adjustment assembly, and the side away from the outer grinding head 2 and the inner grinding head 3 is the rear part. The driver 62 is located in the rear part of the sleeve 15. The central shaft 5 extends into the sleeve 15. The transmission seat 8, the first positioning seat 11, and the first bearing 13 are located in the sleeve 15. The elastic element 62 is at least partially located in the sleeve 15. The guide sleeve 81 is guided and slidably engaged with the inner wall of the sleeve 15 to improve the stability of the guide sleeve 81 during operation. The side of the sleeve 15 is provided with a straight-extending guide groove 151. The guide sleeve 81 is provided with a guide member passing through the guide groove 151. The guide member can be a bolt locked on the guide sleeve 81. The cooperation between the guide groove 151 and the guide member prevents the guide sleeve 81 and the transmission seat 8 from rotating. The guide sleeve 81 and the transmission seat 8 will only move back and forth within the sleeve 15.
