The outer support assembly includes a plurality of outer support blocks, each outer support block is arranged at intervals in the circumferential direction, and the inner wall of each outer support block is used to fit the outer circle of the workpiece, and an annular space for placing the workpiece is formed between the inner support assembly and the outer support assembly.

The driving assembly is used to drive the inner support assembly and the outer support assembly to clamp the workpiece and rotate. The fixing assembly is used to fit the two annular end faces of the workpiece to fix the workpiece. When processing the workpiece, the inner support assembly and the outer support assembly cooperate to clamp the inner circle and the outer circle of the workpiece at the same time.

After the chips are entangled on the tool, if the tool continues to cut the corrugated tooth composite gasket, the cutting resistance of the tool will increase, thereby increasing the wear of the tool and accelerating the damage of the tool. Summary of the invention

When the telescopic rod of the lifting drive member 82 moves upward, it can drive the first stop member 85 to move upward. When the first stop member 85 conflicts with the connecting member 24, the first stop member 85 continues to move upward and can drive the connecting plate 242 to move upward, thereby driving the tool 22 to move upward, so that the first elastic member 23 is compressed.

[0038] like Figure 4-Figure 6 As shown, the emergency lifting member 83 is an electric push rod, and the emergency lifting member 83 is fixed on the mounting seat 21, and the telescopic rod of the emergency lifting member 83 extends into the mounting cavity 211.

A second stopper 86 is fixedly provided at the lower end of the telescopic rod of the emergency lifting member 83, and the second stopper 86 is a circular plate-shaped structure. When the telescopic rod of the emergency lifting member 83 moves upward, it can drive the second stopper 86 to move upward.

[0039] like Figure 4-Figure 6As shown, the damping telescopic rod 84 is vertically arranged, and the damping telescopic rod 84 includes a first rod 841 and a second rod 842. The first rod 841 is slidably inserted in the second rod 842, and the first rod 841 can extend out of the second rod 842.

[0040] like Figure 4-Figure 6 As shown, the position detector 81 is a push-type switch, which is arranged above the pressing plate 88, and the position detector 81 is vertically slidably arranged on the mounting seat 21. A third elastic member 89 is also fixedly arranged on the position detector 81, and the elastic force direction of the third elastic member 89 is in the vertical direction.

One end of the third elastic member 89 is fixedly arranged on the mounting plate 213, and the other end is fixedly arranged on the upper groove wall of the sliding groove 212. During the gasket cutting process, when the cutting resistance encountered by the tool 22 increases so that the tool 22 is lifted to a preset position, the tool 22 can drive the damping telescopic rod 84 and the pressing plate 88 to move upward, so that the pressing plate 88 squeezes the pressing contact 811 of the position detector 81. When the position detector 81 is squeezed, it sends an upward signal to the controller, and the controller controls the lifting drive 82 to drive the tool 22 to rise, so that the tool 22 no longer cuts the gasket.

[0041] like Figure 7-10As shown, the blowing member 3 is a fan, and the blowing member 3 is fixedly arranged on the machine body 1. In the radial direction of the corrugated composite gasket 9, the blowing member 3 is located on the outside of the tool 22, and the blowing direction of the blowing member 3 is toward the inside of the corrugated composite gasket 9. The blowing member 3 can blow the debris cut by the tool 22 to the inside of the tool 22 to prevent the debris from being entangled on the tool 22. The debris collection assembly 4 is fixedly arranged on the machine body 1, and the debris collection assembly 4 includes a guide plate 41, a guide roller 42 and a collection box 43. In the radial direction of the corrugated composite gasket 9, the guide plate 41 is located on the inside of the tool 22. The upper surface of the guide plate 41 is provided with a guide slope 411, and the guide slope 411 extends from bottom to top in the direction from outside to inside. The lower end of the guide slope 411 is lower than the upper surface of the corrugated composite gasket 9, and the upper end of the guide slope 411 is higher than the upper surface of the corrugated composite gasket 9. The guide roller 42 is rotatably arranged at the upper end of the guide plate 41, and the rotation axis of the guide roller 42 is arranged horizontally and perpendicular to the blowing direction of the blowing member 3. The body 1 is also provided with a rotating driving member (not shown in the figure) for driving the guide roller 42 to rotate. The collecting box 43 is located on the inner side of the guide plate 41, and the upper part of the collecting box 43 is open. When working, the blowing member 3 is started, and the blowing member 3 can blow the debris cut by the tool 22 to move upward along the guiding inclined surface 411. When the debris moves to the guide roller 42, the guide roller 42 can drive the debris to continue to move forward until the debris falls into the collecting box 43.

[0042] The implementation principle of the corrugated composite gasket production device of the embodiment of the present invention is as follows: when in use, the corrugated composite gasket 9 to be processed is placed on the supporting roller 51 of the rotating mechanism, and the outer edge of the corrugated composite gasket 9 is clamped in the annular groove 63 of the driving wheel 61, and the inner edge of the corrugated composite gasket 9 is clamped in the annular groove 63 of the driven wheel 62. The first elastic member 23 elastically presses the tool 22 on the gasket, and then controls the driving motor to drive the driving wheel 61 to rotate. When the driving wheel 61 rotates, it cooperates with the driven wheel 62 to drive the corrugated composite gasket 9 to rotate. During the rotation of the corrugated composite gasket 9, the tool 22 cuts a corrugated annular groove 91 on its surface. The blowing member 3 blows the debris cut by the tool 22 to move up along the guide inclined surface 411. When the debris moves to the guide roller 42, the guide roller 42 can drive the debris to continue to move forward until the debris falls into the collection box 43.

[0043] When the long strips of debris cut by the tool 22 are wrapped around the tool 22, the cutting resistance of the tool 22 increases. At this time, the extrusion force on the cutting surface 221 of the tool 22 increases, which will squeeze the tool 22 to move upward and compress the first elastic member 23. At the same time, the tool 22 can drive the pressing plate 88 to move upward. When the tool 22 is lifted to the preset position, the pressing plate 88 just squeezes the pressing contact 811 of the position detector 81, and the position detector 81 sends an ascending signal to the controller. The controller controls the lifting drive 82 to drive the tool 22 to rise, so that the tool 22 no longer contacts the corrugated composite gasket 9. Then the staff cleans up the long strips of debris wrapped around the tool 22, and then controls the lifting drive 82 to drive the tool 22 down to continue processing.

[0044] When the corrugated composite gasket production device of the present invention is in use, when the cutting resistance of the tool 22 increases, the tool 22 will move upward, and then trigger the controller to control the lifting drive 82 to drive the tool 22 to rise, so that the tool 22 no longer contacts the corrugated composite gasket 9, thereby preventing the tool 22 from cutting under a large cutting resistance, delaying the wear of the tool 22, and extending the service life of the tool 22. The blowing member 3 can prevent the debris cut by the tool 22 from being entangled on the tool 22, and the debris collection component 4 can lift the debris, to a certain extent prevent the friction between the debris and the corrugated composite gasket 9 when the corrugated composite gasket 9 rotates, and can also facilitate the collection of the debris.
