[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0028] Example 1
[0029] like Figure 1-4As shown, this utility model embodiment provides a blade impact protection device during cutting, including a processing table 1. A control box 2 is fixedly connected to the top of the processing table 1, and a support plate 3 is fixedly connected to the processing table 1. A moving mechanism 4 is fixedly connected to the top of the processing table 1. The moving mechanism 4 includes a screw 401, a moving block 402, and a vibration sensor 403. The left side of the screw 401 is movably connected to the inner side of the support plate 3, and the right side of the screw 401 extends through to the right side of the support plate 3. The moving block 402 is movably connected to the surface of the screw 401, and the bottom of the vibration sensor 403 is fixedly connected to the moving block 403. At the top of 02, a rotary motor 5 is fixedly connected to the top of the control box 2. The output end of the rotary motor 5 is fixedly connected to the right side of the screw 401. A sliding rod 6 is fixedly connected inside the support plate 3. A moving block 402 is sleeved on the surface of the sliding rod 6. A distance sensor 7 is fixedly connected to the inner side of the support plate 3. Receivers 8 are fixedly connected to the front and rear sides of the moving block 402. A cutting frame 9 is fixedly connected to the bottom of the moving block 402. A cutter 10 is movably connected inside the cutting frame 9. A rotary motor 11 is fixedly connected to the front side of the cutting frame 9. The output end of the rotary motor 11 is fixedly connected to the surface of the cutter 10.
[0030] When the cutter 10 is in use, the screw 401 drives the moving block 402 to move left and right via the moving mechanism 4. The material is cut by the cutter 10. When the vibration of the screw 401 exceeds the threshold, the vibration sensor 403 transmits a signal to the control box 2, which stops the cutter 10 and protects the cutter. The distance sensor 7 can monitor the moving distance of the cutter 10 in real time to ensure the normal use of the cutter 10.
[0031] Example 2
[0032] like Figure 5 As shown, in one embodiment, a cutting groove 12 is provided on the top of the processing table 1. The width of the cutting groove 12 is greater than the width of the cutter 10. A clamping mechanism 13 is fixedly connected to the top of the processing table 1. The clamping mechanism 13 includes a fixed plate 1301, a compression spring 1302 and a push plate 1303. The bottom of the fixed plate 1301 is fixedly connected to the top of the processing table 1. The outer side of the compression spring 1302 is fixedly connected to the inner side of the fixed plate 1301. The outer side of the push plate 1303 is fixedly connected to the inner side of the compression spring 1302. A protective pad 14 is fixedly connected to the inner side of the push plate 1303. The protective pad 14 is made of soft rubber.
[0033] When the part is fixed by the clamping mechanism 13, the compression spring 1302 pushes the push plate 1303 to move and fix the part. By setting the protective pad 14, the friction of the contact surface can be increased when the part is clamped, and the part can be prevented from shifting during cutting.
[0034] In operation, the following steps are taken: First, the material to be cut is placed on the surface of the processing table 1. The push plate 1303 is fixed to the part by the rebound force of the compression spring 1302. Then, the rotating motor 5 is started, which drives the screw 401 to rotate. The screw 401 drives the moving block 402 to move. The moving block 402 moves left and right according to the movement trajectory provided by the sliding rod 6. The moving block 402 drives the cutter 10 to move. The rotating motor 11 drives the cutter 10 to rotate. The cutter 10 cuts the part. When the vibration of the screw 401 exceeds the threshold of the vibration sensor 403, the rotating motor 11 and the rotating motor 5 are stopped by the control box 2, so that the cutter 10 is reset. The control box 2 also alarms to prompt the staff to come for maintenance. The distance sensor 7 and the receiver 8 can monitor the movement distance of the cutter 10 in real time, which is convenient for the staff to perform maintenance and adjustment.
[0035] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
