Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment 1

[0022] Combined with Figures 1-3 , a part clamping device for milling and grinding processing includes a fixed base 1. A length adjustment mechanism is provided on the fixed base 1. A flipping mechanism is provided on the length adjustment mechanism. A width adjustment mechanism is provided on the flipping mechanism.

[0023] Referring to Figure 1 and Figure 3 , it is further obtained that the flipping mechanism includes a vertical plate 2. The number of vertical plates 2 is two. A first motor 3 is fixedly connected to one end of each of the two vertical plates 2 away from each other. A drive shaft 4 is fixedly connected to the driving end of each of the two first motors 3. A flipping plate 5 is fixedly connected to one end of each of the two drive shafts 4 away from the vertical plate 2. A baffle 6 is fixedly connected to the outer wall of each of the two drive shafts 4. A positioning plate 7 is fixedly connected to both sides of the drive shaft 4 corresponding to the side close to the flipping plate 5 at one end of each of the two vertical plates 2.

[0024] Specifically, by controlling the two first motors 3 on both sides through a synchronous controller to drive the drive shafts 4 to rotate and drive the flipping plates 5 to rotate, the workpiece can be quickly turned over, and milling and grinding processing can be performed on the other side. The cooperation of the baffle 6 and the positioning plate 7 can prevent excessive rotation.

[0025] Embodiment 2

[0026] Referring to Figure 1 and Figure 2, and on the basis of the first embodiment, it is further obtained that the length adjusting mechanism includes a first sliding groove 8 opened at the top end of the fixed base 1. Both sides of the inner wall of the first sliding groove 8 are slidably connected with first sliding blocks 9. Both first sliding blocks 9 are fixedly connected to the vertical plate 2. A first bidirectional lead screw 10 is threadedly connected to the inner walls of both first sliding blocks 9. One end of the first bidirectional lead screw 10 is rotatably connected to the first sliding groove 8. One end of the fixed base 1 is fixedly connected with a second motor 11. The driving end of the second motor 11 is fixedly connected to the other end of the first bidirectional lead screw 10.

[0027] Specifically, the second motor 11 drives the first bidirectional lead screw 10 to rotate. Due to the threading effect of the first bidirectional lead screw 10, the first sliding blocks 9 can move towards each other, so as to adjust according to the length of the workpiece and clamp and fix workpieces of different lengths.

[0028] Embodiment Three

[0029] Refer to Figure 1 , and on the basis of the first and second embodiments, it is further obtained that the width adjusting mechanism includes second sliding grooves 12 opened at one end of the turning plate 5 away from the vertical plate 2. Both sides of the inner walls of the two second sliding grooves 12 are slidably connected with second sliding blocks 13. A second bidirectional lead screw 14 is threadedly connected to the inner walls of both groups of second sliding blocks 13 and penetrates through the turning plate 5. Fixing plates 15 are fixedly connected to both groups of second sliding blocks 13. Clamping mechanisms 16 are arranged on both groups of fixing plates 15. The clamping mechanisms 16 are used for clamping workpieces.

[0030] Specifically, the rotation block on the second bidirectional lead screw 14 can be used to rotate the second bidirectional lead screw 14, so that the second sliding blocks 13 can move towards each other, thereby driving the fixing plates 15 to move and the clamping mechanisms 16 to approach each other. Therefore, workpieces of different widths can be clamped and fixed, improving the practicability.

[0031] During the actual operation process, it is necessary to adjust according to the length and width of the workpiece. First, start the second motor 11 to drive the first bidirectional lead screw 10 to rotate. Due to the threading effect of the first bidirectional lead screw 10, the first sliding blocks 9 can move towards each other and drive the vertical plate 2 to move, so as to adjust the length. Then rotate the rotation block to drive the second bidirectional lead screw 14 to rotate. Due to the threading effect of the second bidirectional lead screw 14, the second sliding blocks 13 can move towards each other and drive the fixing plates 15 to move. Therefore, the width can be adjusted. So it can be adjusted according to the length and width of the workpiece, which is applicable to workpieces of different sizes and improves the practicability of the device;

[0032] After the milling and grinding of one side of the workpiece is completed, the first motors 3 on both sides can be controlled by the synchronous controller to drive the drive shaft 4 to rotate. The drive shaft 4 drives the turning plate 5 to rotate. During the rotation, the baffle 6 flips from the positioning plate 7 on one side to the positioning plate 7 on the other side, just flipping 180 degrees, so that the milling and grinding of the other side of the workpiece can be quickly completed without reinstallation, thereby improving the processing efficiency.

[0033] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to the embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
