The clamp 2 is used for clamping the saw blade base body 13, and the clamp 2 is installed on the machine frame 1. Back backer 3 and preceding backer 4 all are located the top of anchor clamps 2, and back backer 3 is fixed in frame 1, has on the back backer 3 to lean on the face, lean on the vertical setting of face. The front backer 4 is positioned in front of the rear backer 3, a third cylinder 5 is fixed on the rack 1, and a piston rod of the third cylinder 5 is fixedly connected with the front backer 4; when the piston rod of the third cylinder 5 is in the extended state, the saw blade base 13 located between the rear backer 3 and the front backer 4 can be clamped, i.e., one side of the saw blade base 13 abuts against the abutting surface of the rear backer 3.
As shown in fig. 1 to 3, a blade body 13 thickness measuring device is located below the rear backer 3, and the blade body 13 thickness measuring device is used for measuring the thickness of the blade body 13 clamped by the jig 2. The saw blade matrix 13 thickness measuring device includes first cylinder 6, second cylinder 7, electron range finding component 8 and limit for journey structure. The first cylinder 6 is located under the rear backer 3, the second cylinder 7 is located right in front of the first cylinder 6, and the first cylinder 6 and the second cylinder 7 are arranged oppositely. The cylinder body of the first cylinder 6 and the cylinder body of the second cylinder 7 are both fixed on the frame 1, the moving directions of the piston rod of the first cylinder 6 and the piston rod of the second cylinder 7 are both vertical to the abutting surface, so that the piston rod of the first cylinder 6 and the piston rod of the second cylinder 7 move horizontally, and the moving directions of the piston rod of the first cylinder 6 and the piston rod of the second cylinder 7 are arranged in parallel.
A piston rod of the first cylinder 6 is fixed with a rear measuring needle 9, the rear measuring needle 9 is made of wear-resistant materials, and the wear-resistant materials are artificial diamond or tungsten steel. A front measuring needle 10 is fixed on the piston rod of the second cylinder 7. The electronic distance measuring element 8 is a laser displacement sensor, such as a loose CMOS type micro laser displacement sensor; the laser displacement sensor is fixed on the machine frame 1, and light beams emitted by the laser displacement sensor irradiate the end face of the piston rod of the second air cylinder 7, so that the laser displacement sensor can measure the moving stroke of the piston rod of the second air cylinder 7.
The stroke limiting structure comprises a stroke limiting plate 11 fixedly connected with the piston rod of the first cylinder 6, a stroke limiting bolt 12 is connected to the stroke limiting plate 11 in a threaded mode, and when the piston rod of the first cylinder 6 extends out, the stroke limiting bolt 12 can abut against the cylinder body of the first cylinder 6, so that the forward movement stroke of the piston rod of the first cylinder 6 is limited. The forward movement stroke of the piston rod of the first cylinder 6 can be adjusted by screwing the stroke-limiting bolt 12.
The function and advantages of the various components will be further explained by illustrating the process of measuring the thickness of the saw blade body 13 by the saw blade body 13 thickness measuring device. When the saw blade matrix 13 thickness measuring device is in a normal state, the piston rod of the first air cylinder 6 and the piston rod of the second air cylinder 7 are both in a retraction state.

Firstly, a piston rod of a first cylinder 6 drives a rear measuring needle 9 to move forwards, the rear measuring needle 9 pushes a saw blade base body 13 to swing forwards, a limit bolt 12 abuts against a cylinder body of the first cylinder 6, and an outer edge part of the saw blade base body 13 and an abutting surface of a rear backrest 3 are ensured to be in a separated state by screwing the bolt; this ensures that the rear side of each saw blade body 13 is positioned consistently when it is in the measuring position.
The above-described operation can be performed during the rotation of the saw blade base 13, so that the friction between the saw blade base 13 and the rear cam 3 is prevented, and the rear measuring pin 9 made of a wear-resistant material has excellent wear resistance, thereby ensuring that the rear side surface of each saw blade base 13 is positioned at the same position in a measuring state within one working day.
Then, the piston rod of the second cylinder 7 drives the front measuring pin 10 to abut against the front side surface of the saw blade base body 13. The thrust of the piston rod of the second cylinder 7 is far smaller than that of the piston rod of the first cylinder 6, so that the saw blade matrix 13 is prevented from moving backwards, and the measurement precision is further ensured.
