DETAILED DESCRIPTION

[0013] The technical solution of the present utility model is further described in detail below through specific implementation methods. Example

[0014] like Figure 1-3 As shown, the utility model provides a cutting device that can test the performance of brazed diamond cutting saw blades, including a base frame 18, a speed regulating motor 1 is provided on the base frame 18, an eccentric wheel 2 is provided at the power output end of the speed regulating motor 1, a linear guide rail 3 and a support rod are provided on the base frame 18, a slider 5 is provided on the linear guide rail 3, a tension spring 4 is provided between the slider 5 and the support rod to force the slider 5 to fit with the eccentric wheel 2; a mounting frame 7 is hingedly provided on the slider 5, an angle grinder 6 is provided on the mounting frame 7, and a power output end of the angle grinder 6 is provided for cutting the profile The diamond saw blade of the present invention is provided with a cylinder 8 at the bottom of the base 18, and the telescopic end of the cylinder 8 passes through the base 18 and abuts against the bottom of the mounting frame 7. The telescopic end of the cylinder 8 is sleeved with a tension spring 9, and the two ends of the tension spring 9 abut against the telescopic end of the cylinder 8 and the base 18 respectively; a guide mechanism 10 for the profile is also provided on the base 18, and a plurality of bolts for limiting the profile are screwed on the guide mechanism 10, and a transverse limiting screw rod 12 for adjusting the cutting length of the profile is also screwed on the base 18; the speed regulating motor 1 is electrically connected to the controller 15 arranged on the base 18.

[0015] In order to facilitate the recording of the cutting time of the diamond saw blade to measure its service life, an infrared sensing time recorder 16 for the contact time between the diamond saw blade and the profile is provided on the base frame 18; in addition, an infrared sensing number counter 17 for the number of times the diamond saw blade contacts the profile is also provided on the base frame 18; the infrared sensing time and the infrared sensing number counter 17 are both electrically connected to the controller 15.

[0016] In order to facilitate the pushing of the profile to be cut toward the cutting saw blade, one end of the profile away from the transverse limiting screw rod 12 is connected to one end of the pull rope, and the other end of the pull rope passes around the pulley assembly 11 set on the base frame 18 and is connected to the gravity weight 14.

[0017] The specific working principle of the present invention is as follows: when the speed regulating motor 1 rotates, the eccentric wheel 2 starts to rotate. When the eccentric wheel 2 rotates, the slider 5 slides back and forth in contact with the linear guide rail 3. When the infrared sensing times counter 17 senses the cutting saw blade, it indicates that the cutting saw blade has started to contact the profile and cut. At this time, the infrared sensing time recorder 16 also starts timing. After the cutting saw blade cuts the profile, the controller 15 controls the telescopic end of the cylinder 8 to extend, the angle grinder 6 rises, and the cutting saw blade rises accordingly. At this time, the cutting saw blade leaves the sensing area of the infrared sensing times counter 17 and completes one count. At the same time, the infrared sensing time recorder 16 ends the cutting timing. At the same time, driven by the gravity of the gravity weight 14, the profile to be cut moves forward to the position of the horizontal limit screw 12. As the speed regulating motor 1 rotates, the angle grinder 6 retreats and then performs the next cut.

[0018] Finally, the cumulative number of cuts and the cutting time will be displayed on the controller 15.

[0019] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and not to limit it; although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents; without departing from the spirit of the technical solution of the utility model, they should all be included in the scope of the technical solution for protection of the utility model.
