Description

Technical Field

[0001] This utility model belongs to the technical field of glass processing equipment, specifically relating to a coaxial double grinding wheel assembly. Background Technology

[0002] Glass edging is a conventional glass processing technique. It typically involves different processing steps such as rough grinding and fine grinding. Glass processing equipment is equipped with different grinding head assemblies depending on the specific process. In existing technology, each grinding head assembly contains only one grinding head, resulting in a significant space requirement when using two or more assemblies, which presents limitations. For example, Chinese patent application CN201510866126.1 discloses a rough grinding head structure for a glass edging machine. This structure includes a support, a grinding wheel mounting head for mounting the grinding wheel, and a synchronous control component for controlling the rotation and lifting of the grinding wheel mounting head. The synchronous control component is mounted on the support and connected to the grinding wheel mounting head. This structure contains only one grinding head, requiring two independent grinding head structures to achieve different processing steps. This also results in a significant space requirement and limitations, necessitating further improvements. Utility Model Content

[0020] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model 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 full understanding of this utility model. However, this utility model can be implemented 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 this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0021] like Figure 1-4 As shown, this coaxial dual grinding wheel assembly is used in glass processing equipment, such as a glass edging machine, and includes: Base frame 1; The dual grinding wheel assembly is mounted on a base frame 1. The assembly includes an inner grinding wheel 2, an outer grinding wheel 3, an inner wheel drive device 4 connected to the inner grinding wheel 2, and an outer wheel drive device 5 connected to the outer grinding wheel 3. The inner wheel drive device 4 drives the inner grinding wheel 2 to rotate, and the outer wheel drive device 5 drives the outer grinding wheel 3 to rotate. The inner grinding wheel 2 is located inside the outer grinding wheel 3 and is coaxially arranged with the outer grinding wheel 3. The inner grinding wheel 2 and the outer grinding wheel 3 are grinding heads with different grit numbers, adapting to different glass processing methods such as rough grinding and fine grinding. This invention integrates the inner grinding wheel 2 and the outer grinding wheel 3 onto the base frame 1, replacing the traditional method of setting two grinding heads on two separate devices. Furthermore, the coaxial arrangement of the inner grinding wheel 2 and the outer grinding wheel 3 facilitates the miniaturization of the entire structure and reduces the space occupied by the glass processing equipment.

[0022] The first adjustment device 6 has a base frame 1 mounted on its movable part. The base frame 1 moves with the movable part of the first adjustment device 6. In this embodiment, the movable part of the first adjustment device is the subsequent first moving seat 64. When the first adjustment device 6 is running, it is used to adjust the double grinding wheel assembly to move back and forth along the axial direction of the inner grinding wheel 2 (which is also equivalent to the axial direction of the outer grinding wheel 3), that is, to adjust the inner grinding wheel 2 and the outer grinding wheel 3 at the same time.

[0023] The second adjusting device 7 is mounted on the base frame 1. The inner wheel drive device 4 is mounted on the movable part of the second adjusting device 7 and moves with the movable part of the second adjusting device 7. In this embodiment, the movable part of the second adjusting device 7 is the subsequent second moving seat 71. When the second adjusting device 7 is running, it is used to adjust the inner grinding wheel 2 and the inner wheel drive device 4 to move back and forth along the axial direction of the inner grinding wheel 2, which can change the axial relative position of the inner grinding wheel 2 and the outer grinding wheel 3. When the present invention requires the inner grinding wheel 2 to be processed, the second adjusting device 7 adjusts the inner grinding wheel 2 to be further outward than the outer grinding wheel 3. That is, in this embodiment, the inner grinding wheel 2 moves away from the base frame 1 and protrudes out of the outer grinding wheel 3, so that the inner grinding wheel 2 contacts the glass on the glass processing equipment. When the present invention requires the outer grinding wheel 3 to be processed, the second adjusting device 7 moves the inner grinding wheel 2 in the opposite direction and completely retracts into the outer grinding wheel 3. That is, in this embodiment, the inner grinding wheel 2 moves closer to the base frame 1, so that the outer grinding wheel 3 contacts the glass on the glass processing equipment.

[0024] In some embodiments of this utility model, such as Figure 1-3As shown, the first adjusting device 6 includes a base 61, a first screw 62 mounted on the base 61, a nut sleeve 63 mounted on the first screw 62, a first movable seat 64 mounted on the nut sleeve 63, and a first adjusting motor 65 mounted on the base 61 and connected to the first screw 62. The first adjusting motor 65 has a motor shaft. The coaxial double grinding wheel assembly of this utility model is mounted on a glass processing equipment via the base 61. The base frame 1 is fixedly mounted on the first movable seat 64. When the first adjusting motor 65 is running, it drives the first movable seat 64 and the base frame 1 to move through the first screw 62 and the nut sleeve 63, thereby simultaneously adjusting the inner grinding wheel 2 and the outer grinding wheel 3.

[0025] In some embodiments of this utility model, such as Figure 1-4 As shown, the first adjusting device 6 includes a gearbox 66, a driving gear 67 rotatably disposed within the gearbox 66, a first manual adjusting rod 68 connected to and rotating synchronously with the driving gear 67, and a driven gear 69 disposed on the motor shaft of the first adjusting motor 65 and rotating synchronously with the motor shaft. The motor shaft of the first adjusting motor 65 is connected to the first screw 62 via a coupling. This type of connection is common knowledge in the art. The driving gear 67 and the driven gear 69 are connected in a transmission manner. The first manual adjusting rod 68 is located on the side of the first adjusting motor 65. The gearbox 66 is fixedly disposed on the outside of the base 61. By operating the first manual adjusting rod 68, the operator causes the driving gear 67 and the first manual adjusting rod 68 to rotate synchronously, driving the driven gear 69 to rotate. This causes the motor shaft of the first adjusting motor 65 to rotate, driving the first screw 62 to rotate, thereby realizing the adjustment of the nut sleeve 63, the first moving seat 64, the base frame 1 and its inner grinding wheel 2 and outer grinding wheel 3. That is, the first adjusting device 6 can be electrically and manually adjusted, improving the adjustment flexibility.

[0026] In some embodiments of this utility model, such as Figure 1-3 As shown, the second adjustment device 7 includes a second movable seat 71 movably mounted on the base frame 1, a second screw 72 rotatably mounted on the base frame 1, and a cap 73 located at the outer end of the second screw 72. The second screw 72 and the second movable seat 71 are connected by a threaded transmission. The inner wheel drive device 4 is fixed on the second movable seat 71. The operator drives the second screw 72 to rotate by operating the cap 73. The threaded transmission between the second screw 72 and the second movable seat 71 drives the second movable seat 71 and the inner wheel drive device 4 to move, thereby adjusting the axial position of the inner grinding wheel 2.

[0027] In some embodiments of this utility model, such as Figure 1-3As shown, the base frame 1 is provided with a guide section 11 for guiding the second moving seat 71 to move axially along the inner grinding wheel 2. The base frame 1 is provided with an upper limit plate 12 located above the guide section 11. The first moving seat 64 is located below the guide section 11. The upper limit plate 12 and the first moving seat 64 are used to limit the vertical position of the second moving seat 71 and improve the stability of the movement of the second moving seat 71. The upper limit plate 12 is located on the movement path of the inner wheel drive device 4. In this embodiment, the front part of the coaxial double grinding wheel assembly is taken as the side of the inner grinding wheel 2 and the outer grinding wheel 3, and the rear part of the coaxial double grinding wheel assembly is taken as the side away from the inner grinding wheel 2 and the outer grinding wheel 3. The inner grinding wheel 2 moves in the forward direction. When the inner wheel drive device 4 contacts the upper limit plate 12, the second moving seat 71 reaches the maximum forward movement position. The inner grinding wheel 2 moves in the rear direction. When the second moving seat 71 contacts the rear part of the guide section 11, the second moving seat 71 reaches the maximum rearward movement position.

[0028] In some embodiments of this utility model, such as Figure 1-3 As shown, the inner wheel drive device 4 includes an inner wheel drive motor 41. The output end of the inner wheel drive motor 41 is fixedly connected to the inner grinding wheel 2. The inner wheel drive motor 41 is fixedly mounted on the second movable seat 71. When the inner wheel drive motor 41 is running, it drives the inner grinding wheel 2 to rotate.

[0029] In some embodiments of this utility model, such as Figure 1-3 As shown, the outer wheel drive device 5 includes an outer wheel drive motor 51 fixedly mounted on the base frame 1, a drive pulley 52 mounted on the motor shaft of the outer wheel drive motor 51, a fixed cylinder 53 mounted on the base frame 1, a rotating cylinder 55 rotatably mounted outside the fixed cylinder 53 via a bearing 54, and a belt 56 connecting the drive pulley 52 and the rotating cylinder 55. The outer grinding wheel 3 is fixedly mounted at the outer end of the rotating cylinder 55 away from the base frame 1. The side of the rotating cylinder 55 is provided with a toothed groove that mates with the belt 56. When the outer wheel drive motor 51 is running, it drives the outer grinding wheel 3 to rotate through the drive pulley 52, the belt 56, and the rotating cylinder 55.

[0030] In some embodiments of this utility model, such as Figure 2-3 As shown, the fixed cylinder 53 has a channel 531 inside for the output end of the inner wheel drive motor 41 to extend into and connect with the inner grinding wheel 2, so that the inner grinding wheel 2 and the outer grinding wheel 3 can be set coaxially.

[0031] In some embodiments of this utility model, such as Figure 1-3 As shown, the outer wheel drive motor 51 is located above the inner wheel drive motor 41.
