[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-4 The utility model provides a technical solution: a continuous cutting device for metal housing parts of a projector, comprising:

[0031] A positioning assembly 1, which includes a supporting plate 11, a pushing plate 12, a screw 13 and an end baffle 14. The housing member 9 to be cut is placed on the supporting plate 11. The cross section of the pushing plate 12 is an inverted "L" shape. One end of the housing member 9 to be cut extends into a positioning groove surrounded by the pushing plate 12 and the supporting plate 11. A bearing 121 is provided on the back of the pushing plate 12. The outer ring of the bearing 121 is fixedly mounted on the back of the pushing plate 12. One end of the screw 13 is fixedly mounted on the inner ring of the bearing 121, and a rotating handle 131 is provided on the other opposite end. The screw 13 is inserted into a connecting seat 132. The screw 13 is threadedly connected to the connecting seat 132. The end baffle 14 is provided on one side of the pushing plate 12.

[0032] A transverse movement assembly, comprising a mounting platform 2 and a slide rail 21, wherein a support plate 11 is slidably connected to the slide rail 21;

[0033] The cutting component is arranged at one end of the positioning component 1 .

[0034] The continuous cutting device can realize the fixed-length cutting of different lengths of the shell members 9 to be cut, and can ensure that the two end surfaces of the shell members 9 to be cut are flat. In addition, the continuous cutting device can realize the synchronous cutting of multiple shell members 9 to be cut, thereby improving the cutting efficiency.

[0035] The cutting assembly includes a driving cylinder 3 and a cutter 31 . The driving cylinder 3 is used to drive the cutter 31 downward to cut the housing member 9 to be cut.

[0036] A rotating connection seat 22 is provided below the mounting platform 2, and the output shaft of the rotating motor 4 is connected to the rotating connection seat 22. The rotating motor 4 can rotate by driving the rotating connection seat 22 to make the mounting platform 2 tilt and rotate as a whole. Since the cut waste is temporarily stored in the positioning groove surrounded by the push plate 12 and the support plate 11, in order to facilitate the cleaning of the cut waste, the mounting platform 2 is rotated and tilted as a whole, so that the cut waste slides out under the action of gravity.

[0037] Symmetrically arranged guide rods 122 are provided on both sides of the push plate 12 , and the guide rods 122 are passed through the connecting seat 132 to facilitate smooth movement of the push plate 12 .

[0038] The end of the guide rod 122 is threadedly connected to the push plate 12 to facilitate the removal of the guide rod 122 .

[0039] The connecting seat 132 is provided with a notch whose shape matches that of the guide rod 122 , so as to further facilitate the removal of the guide rod 122 .

[0040] The rotating handle 131 is a hand wheel, which is convenient for rotating the screw rod 13 to accurately adjust the position of the push plate 12, thereby adjusting the accuracy of fixed-length cutting.

[0041] Working principle: When the shell parts 9 to be cut are to be cut to a fixed length, first slide a plurality of closely arranged shell parts 9 to be cut into the positioning groove formed by the push plate 12 and the upper surface of the support plate 11, and the end baffle 14 on the side away from the operator's feeding is pressed against the outer shell parts 9 to be cut at the edge. Then, the screw rod 13 is rotated so that the length of the shell parts 9 to be cut extending out of the support plate 11 is different, so as to achieve a fixed length, and the driving cylinder 3 drives the cutter 31 downward to cut the part of the shell parts 9 to be cut extending out of the support plate 11, so as to perform the first cutting. Then, the support plate 11 on the mounting platform 2 slides horizontally along the slide rail 21, so that the push plate 12 moves to the bottom of the cutter 31, and then the driving cylinder 3 drives the cutter 31 downward to perform a second cutting, so as to cut off the part of the shell parts 9 to be cut extending out of the push plate 12, so as to achieve a fixed length cutting of the shell parts 9 to be cut.
