DETAILED DESCRIPTION

[0024] 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 in 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.

[0025] See also Figure 1 The utility model provides a technical solution: a saw blade end surface flatness detector, comprising: a fixed base 1 and a dial indicator 10, a driving motor 2 is installed on the top of the fixed base 1, the output end of the driving motor 2 is connected to a rotating shaft 3 through a coupling, a positioning block 4 is installed on the outer side of the rotating shaft 3, a saw blade body 5 is sleeved between the positioning block 4 and the outer side of the rotating shaft 3, a measuring rod 6 is arranged on one side of the saw blade body 5, a fixing frame 7 is sleeved on the outer side of the measuring rod 6, a first sliding block 8 is connected between the bottom of the fixing frame 7 and the slide groove of the fixed base 1, a screw 9 penetrating the fixed base 1 is connected to one side of the first sliding block 8, and a dial indicator 10 is installed on the side of the measuring rod 6 away from the saw blade body 5;

[0026] A guide rod 11 installed in the groove of the fixing frame 7 is connected through the middle of the measuring rod 6, a pull rod 12 is connected through the top of the measuring rod 6, and a movable rod 13 is connected between the pull rod 12 and the groove of the measuring rod 6;

[0027] A movable spring 14 is installed between the movable rod 13 and the groove of the measuring rod 6, a first connecting rod 15 is installed on the side of the movable rod 13 away from the movable spring 14, a second slider 16 is provided on one side of the first connecting rod 15 through a slide groove, a rotating rod 17 is connected between the two groups of second sliders 16 through a rotating shaft, a clamping block 18 is installed on one side of the first connecting rod 15, a protrusion 19 is provided between the two groups of clamping blocks 18, the protrusion 19 is installed on the inner wall of the groove of the fixing frame 7, and the middle of the rotating rod 17 is connected to the groove of the measuring rod 6 through a rotating shaft.

[0028] In specific implementation, when the position of the measuring rod 6 needs to be adjusted, the pull rod 12 can be pulled to one side so that the pull rod 12 drives the movable rod 13 to move to one side, and the movable spring 14 is squeezed by the movable rod 13. One side of the movable rod 13 is connected to the first connecting rod 15, and the ends of the two groups of first connecting rods 15 close to each other are connected to the second slider 16 through the slide groove, and a rotating rod 17 is connected between the two groups of second sliders 16 through a rotating shaft. Under the force of the movable rod 13, one group of the first connecting rods 15 moves, and is rotated by the second slider 16 and the slide groove. The rod 17 rotates, so that the rotating rod 17 rotates through the middle rotating shaft. When the rotating rod 17 rotates, it pushes the first connecting rod 15 on the other side to move, so that the two groups of first connecting rods 15 move away from each other. The movement of the first connecting rod 15 causes the two groups of clamping blocks 18 to move away from each other, and at the same time, the clamping blocks 18 are separated from the protrusions 19. Without the docking of the clamping blocks 18 and the protrusions 19, the measuring position of the measuring rod 6 can be adjusted, so that the measuring rod 6 can slide along the groove of the fixing frame 7, and the measuring rod 6 is subjected to the force of the guide rod 11 when moving, which makes the measuring rod 6 more stable during the movement.

[0029] When it is necessary to limit and fix the measuring rod 6, the pull rod 12 can be loosened. At this time, the movable spring 14 will drive the movable rod 13 to reset and push the first connecting rod 15 to move. At the same time, with the cooperation of the second slider 16 and the slide groove, the two groups of first connecting rods 15 move closer to each other and drive the block 18 to dock with the protrusion 19. Through the cooperation of the block 18 and the protrusion 19, the measuring rod 6 can be limited and fixed, thereby ensuring the stability of the measuring rod 6.

[0030] See also Figure 2 , Figure 3 and Figure 4 It can be seen that, during use, the measuring height of the measuring rod 6 can be adjusted according to the measurement requirements of the saw blade body, so as to meet the measurement requirements of saw blade bodies 5 of different sizes.

[0031] One end of the rotating shaft 3 is connected to a mounting block 20, and one side of the mounting block 20 is installed with an insertion rod 21 that passes through the saw blade body 5 and the positioning block 4. Both ends of the insertion rod 21 are connected to rotating blocks 22 through rotating shafts, and a return spring 23 is installed between the rotating block 22 and the groove of the mounting block 20. A second connecting rod 24 is arranged between the two groups of rotating blocks 22, and a connecting block 25 that passes through the insertion rod 21 is installed on one side of the second connecting rod 24. The middle of the rotating block 22 is connected to the groove of the insertion rod 21 through a rotating shaft.

[0032] During specific implementation, when the saw blade end surface flatness detector needs to replace the saw blade body 5, the connecting block 25 can be pulled to the side away from the mounting block 20, and the connecting block 25 will drive the second connecting rod 24 to move. Since the rotating block 22 is set in the groove of the second connecting rod 24, the movement of the second connecting rod 24 will squeeze one end of the rotating block 22 through the groove. The one end of the rotating block 22 is squeezed and rotated through the rotating shaft, so that the rotating block 22 can be rotated and retracted into the groove of the insertion rod 21. There is no limitation of the rotating block 22, and then the insertion rod 21 can be quickly moved out of the groove of the positioning block 4, and the mounting block 20 can be removed from one side of the saw blade body 5 at the same time. There is no limiting effect of the mounting block 20 on the saw blade body 5, so the saw blade body 5 can be removed from the outside of the rotating shaft 3, which is convenient for replacing the saw blade body 5.

[0033] On the contrary, when the saw blade needs to be installed, loosen the connecting block 25 so that the second connecting rod 24 does not squeeze the rotating block 22, and then the rotating block 22 will rotate in the opposite direction through the reset spring 23. At this time, the rotating block 22 will rotate to the outside of the insertion rod 21, and the insertion rod 21 can be limited in the through hole of the positioning block 4 through the rotating block 22, so that the mounting block 20 can be quickly and conveniently connected to one side of the rotating shaft 3, and the saw blade body 5 is limited by the mounting block 20 and the positioning block 4, so it can be stably installed on the outside of the rotating shaft 3.

[0034] See also Figure 1 , Figure 5 , Figure 6 and Figure 7 It can be seen that when in use, the mounting block 20 can be removed from one side of the rotating shaft 3, and then the saw blade body 5 can be quickly removed from the outside of the rotating shaft 3, so that the saw blade body 5 can be quickly replaced.

[0035] To sum up: when the saw blade end surface flatness tester is in use, the saw blade body 5 to be tested can be fixed on the outer side of the rotating shaft 3 through the mounting block 20 and the positioning block 4, and the screw 9 can be rotated according to the position of the saw blade body 5. Since the screw 9 and the fixed base 1 are threadedly connected, and the screw 9 is connected to the first slider 8 through a bearing, the rotating screw 9 will push the first slider 8 to move, so that the first slider 8 drives the measuring rod 6 to move through the fixed frame 7. After the measuring rod 6 is moved to one side of the saw blade body 5, the transmission motor is started again, so that the transmission motor drives the saw blade body 5 to rotate through the rotating shaft 3. When the saw blade body 5 rotates, the measurement data can be displayed on the dial indicator 10 through the measuring rod 6. The flatness value of the saw blade body 5 can be understood by observing the dial indicator 10. This is the use feature of the saw blade end surface flatness tester.
