DETAILED DESCRIPTION

[0025] The following is combined with Figure 1 To Attachment Figure 5 The principles and features of the present invention are described in detail with reference to the embodiments; the examples are only used to explain the present invention, and are not used to limit the scope of the present invention.

[0026] A multifunctional CNC mirror grinding processing center includes a machine tool frame 1, a part fixture 2, a first slide 3, a second slide 4 and a grinding assembly 5. In this embodiment, two first slides 3 are provided, four second slides 4 are provided, and two grinding assemblies 5 are provided.

[0027] See attached Figure 1 The machine tool frame 1 has two mutually perpendicular mounting surfaces, wherein the part fixture 2 is fixedly mounted at the center of the horizontal mounting surface of the machine tool frame 1. Two first slide plates 3 are disposed on both sides of the part fixture 2 and are slidably connected to the machine tool frame 1. Specifically, a lead screw and a guide rail are connected to the vertical mounting surface of the machine tool frame 1, and the two first slide plates 3 are respectively slidably connected to the machine tool frame 1 through the guide rails, and the first slide plates 3 are driven to slide horizontally by a motor and a lead screw, and the two first slide plates 3 are respectively driven by different motors and lead screws. Based on this, the first slide plate 3 can slide horizontally to approach or move away from the part fixture 2.

[0028] Two second slide plates 4 are slidably connected to each first slide plate 3. Specifically, a guide rail and a lead screw are also provided on the first slide plate 3. The two second slide plates 4 are slidably connected to the first slide plate 3 through the guide rails. The second slide plates 4 are driven to slide vertically by a motor and a lead screw. The two second slide plates 4 are driven by different motors and lead screws. Based on this, the second slide plates 4 can slide up and down to approach or move away from the part fixture 2.

[0029] The grinding assembly 5 corresponds to the second slide 4 one by one, that is, each second slide 4 is connected to a grinding assembly 5. The grinding assembly 5 is disposed at four positions of the part 8, namely, up, down, left, and right. Specifically, the grinding assembly 5 includes a grinding tool 6 and a driving assembly 7 for driving the grinding tool 6, wherein the grinding assembly 5 includes a first bracket 9, a first driver 10, a sleeve 11, and a transmission shaft 12, wherein the first driver 10 is fixedly connected to the first bracket 9, the transmission shaft 12 is rotationally connected to the sleeve 11, the first driver 10 is transmission-connected to the transmission shaft 12 through a pulley and a belt, the grinding tool 6 is fixedly connected to the end of the transmission shaft 12, and the grinding tool 6 is driven to rotate by the first driver 10 to complete the part cutting task.

[0030] In order to achieve fine adjustment of the grinding tool 6, a first support shaft 13 is connected to the first bracket 9, and the first bracket 9 is rotatably connected to the second slide 14 through the first support shaft 13. A first locking hole 14 is provided on the fitting surface of the first bracket 9 and the second slide 4. The first locking hole 14 is a waist-shaped hole in the shape of an arc, and a fastener (bolt) passes through the first locking hole 14 to relatively fix the first bracket 9 and the second slide 4. When it is necessary to adjust the grinding angle of the grinding tool 6 in this direction, the fastener can be loosened, the grinding assembly 5 can be rotated to a suitable angle, and then the fastener can be tightened. Since the first locking hole 14 is in the shape of an arc, it plays a limiting role on the grinding assembly 5 in the circumferential direction so that the grinding assembly 5 can only be fine-tuned but not adjusted significantly. Furthermore, the first bracket 9 is connected with a second support shaft 15, and the sleeve 11 is rotatably connected with the first bracket 9 through the second support shaft 15; a second locking hole 16 is provided on the fitting surface of the sleeve 11 and the first bracket 9, and the second locking hole 16 is a waist-shaped hole in the shape of an arc, and the fastener passes through the second locking hole 16 to relatively fix the first bracket 9 and the sleeve 11. When it is necessary to adjust the grinding angle of the grinding tool 6 in this direction, the fastener can be loosened, the sleeve 11 can be rotated to a suitable angle, and then the fastener can be tightened. Similarly, the second locking hole 16 is in the shape of an arc, so it plays a limiting role on the sleeve 11 in the circumferential direction so that the sleeve 11 can only be fine-tuned but not adjusted greatly; since the first driver 10 and the transmission shaft 12 are connected by a pulley and a belt, therefore, when the sleeve 11 is fine-tuned at a certain angle, it does not affect the power transmission between the first driver 10 and the transmission shaft 12.

[0031] The two grinding assemblies 5 located above the part 8 are respectively connected with a trimming assembly 17, which mainly includes a grinding blade and a driver for driving the grinding blade to rotate. A guide rail, a motor and a lead screw are arranged on the first bracket 9. The trimming assembly 17 is slidably connected with the first bracket 9 through the guide rail, and the trimming assembly 17 is driven by the motor and the lead screw to slide up and down to approach or move away from the grinding tool 6. Based on this, each trimming assembly 17 can complete the trimming of two grinding tools 6.

[0032] The device is suitable for grinding disc-type parts. In this embodiment, the part fixture 2 is a three-jaw chuck, which can also be replaced by other existing types of fixtures.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
