The four side clamping plates 12 enclose a space for clamping disc spring raw materials.

[0048] refer to Figure 3 The first drive 10 drives the clamping frame 9 to move in the horizontal direction through the extension and contraction of its output end. The controller 7 synchronously controls the horizontal movement of the first drive 10 and the clamping action of the electric push rod 11 to ensure that the disc spring material is fixed without deviation during the cutting process. The electric push rod 11 drives the clamping plate 12 to shrink synchronously to form a four-way clamping space.

[0049] It should be noted that the first drive 10 may be a cylinder.

[0054] refer to Figure 6 , the detection ball 1873 is a spherical structure, and the pressure sensor 1874 detects whether the smoothness of the inner wall of the disc spring is qualified by sliding contact with the inner wall of the disc spring. The critical contact between the guide tube 1871 and the outer wall of the spring 1872 prevents the spring 1872 from generating linear deformation when the lifting plate 18 rotates. The pressure sensor 1874 is electrically connected to the controller 7, and the rotation drive 17 rotates at a uniform speed, driving the lifting plate 18 to rotate in a uniform circular motion between the inner walls. At this time, the pressure sensor 1874 records the detection value by contacting the inner wall at a uniform speed, and converts the electrical signal into a digital signal through the built-in analog-to-digital converter and sends it to the controller 7. The controller 7 compares the received digital signal with the qualified inner wall smoothness data built therein, thereby judging whether the inner wall smoothness of the disc spring after cutting is qualified;

[0055] The rotary drive 17 drives the lifting plate 18 to rotate at a constant speed to ensure that the pressure sensor 1874 contacts the inner wall evenly to avoid detection errors.

[0056] There are three groups of pressure sensors 1874 arranged inside the mounting cavity 187. The three groups of pressure sensors 1874 are vertically distributed, and the detection coverage rate reaches 100%.

[0057] refer to Figure 6 , the three groups of pressure sensors 1874 are evenly distributed in the vertical direction of the installation cavity 187, so that the smoothness of multiple locations on the inner wall of the disc spring can be detected at the same time.

[0059] refer to Figure 5 and Figure 7 The fourth drive 184 drives the mounting frame 185 to move horizontally by extending and retracting the output end. The grinding drive 1853 drives the pulley 1854 fixedly connected to the top thereof to rotate by rotating the output shaft. The belt 1855 sleeved between the two pulleys 1854 indirectly drives the grinding roller 186 to rotate, thereby achieving the effect of grinding the uneven inner wall of the disc spring.

[0060] It should be noted that the fourth drive 184 may be a cylinder, and the grinding drive 1853 and the moving drive 1858 may be motors.

[0061] A limiting groove 1851 is provided on the side wall of the mounting frame 185 , and a limiting block (not shown in the figure) is fixedly connected to the movable plate 1852 , and the limiting block is slidably connected to the limiting groove 1851 .

[0062] refer to Figure 7 The limiting groove 1851 is slidably connected to the limiting block fixedly connected to the moving plate 1852, so as to prevent the threaded rod 1856 from rotating when driving the moving plate 1852 to move in the vertical direction.

[0063] A conveying assembly 6 is arranged on the outside of the bed frame 1, and the conveying assembly 6 includes a bracket 61, on which a conveyor belt 62 is arranged, one end of the bracket 61 is fixedly connected to a feeding drive 63, and a gear 65 is fixedly connected to the output shaft of the feeding drive 63.

Under the instruction of the controller 7, the unloading robot arm 5 moves the qualified products to the conveyor belt 62, and the feeding drive 63 starts the transmission at the same time to realize continuous production.

[0065] It should be noted that the feeding drive 63 can be a motor.

[0066] A protective cover 64 is disposed outside the gear 65 , and the protective cover 64 may be made of stainless steel.

[0067] refer to Figure 2 and Figure 8 The first guide wheel 19 is arranged on the side of the upper wire rack 25 close to the column 24, the second guide wheel 19 is arranged on the side of the upper wire rack 25 away from the column 24, the fourth guide wheel 19 is arranged on the side of the lower wire rack 26 close to the column 24, and the third guide wheel 19 is arranged on the side of the lower wire rack 26 away from the column 24.

[0069] The pressure sensor 1874 converts the detection value into a digital signal and sends it to the controller 7. If the detection value is compared with the qualified threshold preset by the controller 7 and passes, the lifting plate 18 is driven to move vertically upward by extending the output end of the third drive 16 upward, so that the inner circle of the cut disc spring is taken out, and then the controller 7 controls the unloading robot arm 5 to move the taken out inner circle to the wire cutting component 2 on the other side for further processing, so that it is processed into a disc spring with smaller specifications, and the outer circle of the disc spring can continue to be cut;

[0070] The pressure sensor 1874 converts the detection data into a digital signal and sends it to the controller 7. If the detection data of the pressure sensor 1874 is compared with the qualified data built into the controller 7 and the result is unqualified, the controller 7 controls the output shaft of the fourth drive 184 to extend, thereby driving the mounting frame 185 to move in the direction toward the grinding hole 182, and starts the mobile drive 1858. The mobile drive 1858 drives the threaded rod 1856 to rotate by rotating the output shaft, and indirectly drives the movable plate 1852 to move in the vertical direction, thereby adjusting the height of the grinding roller 186 to the required grinding height, and starts the grinding drive 1853. The grinding drive 1853 drives the pulley 1854 on the top to rotate, and the belt 1855 set between the two pulleys 1854 drives the grinding roller 186 to rotate. , then the controller 7 starts the rotary drive 17 to rotate, starts the output end of the third drive 16 to slowly reciprocate twice in the vertical direction, then turns off the power of the grinding drive 1853, the rotary drive 17 and the third drive 16, and uses the pressure sensor 1874 to detect the smoothness of the inner wall of the disc spring again. If the detection data of the pressure sensor 1874 is compared with the qualified data built in the controller 7 and the result is qualified, the lifting plate 18 is driven to move vertically upward by extending the output end of the third drive 16 upward, so that the inner circle of the cut disc spring is taken out, and then the controller 7 controls the unloading robot arm 5 to move the taken out inner circle to the wire cutting component 2 on the other side for processing again, so that it is processed into a disc spring with smaller specifications, and the outer circle of the disc spring can continue to be cut;

[0071] If the comparison result between the detection data of the pressure sensor 1874 and the qualified data built into the controller 7 is still unqualified, the controller 7 controls the unloading robot arm 5 to take out the unqualified plate from the clamping rack 9 and place it in the placement rack 3 for centralized processing.
