Description

Technical Field

[0001] The utility model relates to the technical field of diamond saw blades, in particular to an auxiliary fixture for diamond saw blades. Background Art

[0002] A diamond saw blade is a cutting tool widely used in the processing of hard and brittle materials such as concrete, refractory materials, stones, and ceramics. A diamond saw blade mainly consists of two parts: a matrix and a cutting head. The matrix is the main supporting part for bonding the cutting head.

[0003] At present, diamond saw blades are applied to a variety of cutting devices. During installation, corresponding fixtures are required for fixation so that the diamond saw blade can rotate at high speed along with the drive shaft of the cutting device. Currently, when clamping and installing a diamond saw blade, a clamping piece is installed on the drive shaft, then the diamond saw blade is installed on the drive shaft, and then another clamping piece is installed on the drive shaft. Finally, a bolt is tightened on the drive shaft so that the two clamping pieces clamp and fix the diamond saw blade, and the installation of the diamond saw blade can be completed.

[0004] In the prior art, during the process of using a fixture to install and clamp a diamond saw blade, the two clamping pieces fix the diamond saw blade through bolts. Since the two clamping pieces only clamp the diamond saw blade and cannot limit its position, after long-term use, the connecting parts between the two clamping pieces and the diamond saw blade will wear, which will affect the installation stability of the diamond saw blade. Moreover, the bolts will also become loose due to equipment vibration, posing a safety hazard and having low safety, so improvement is needed. Summary of the Utility Model

[0006] To achieve the above purpose, the utility model provides the following technical solution: an auxiliary fixture for diamond saw blades, including a housing and a rotating shaft passing through the housing and movably connected to the housing, and a diamond saw blade body arranged on the right side of the housing. A fixed rod is installed at the right end of the rotating shaft, a first clamping ring is installed on the outer side wall of the fixed rod, four uniformly distributed limiting grooves are formed on the right side wall of the first clamping ring, four uniformly distributed clamping grooves are formed on the inner side wall of the inner hole of the diamond saw blade body, a limiting ring is arranged on the right side of the diamond saw blade body, and four clamping blocks respectively matching with the four clamping grooves are installed on the outer side wall of the limiting ring;

[0007] A second clamping ring is arranged on the right side of the limiting ring. Four uniformly and circumferentially distributed limiting rods are installed on the left side wall of the second clamping ring. A fixing frame is arranged on the right side of the second clamping ring. A threaded rod is installed on the right side wall inside the fixing frame, and the left end of the threaded rod extends to the outside of the fixing frame.

[0008] To facilitate the limiting rod to pass through the through hole and insert into the limiting groove, as an optimization of the diamond saw blade auxiliary fixture of the present utility model, through holes are penetrated through the outer side wall of the clamping block.

[0009] To facilitate the connection of the threaded rod and the threaded groove, as an optimization of the diamond saw blade auxiliary fixture of the present utility model, a threaded groove is opened at the right end of the fixing rod.

[0010] To facilitate pressing the stopper into the groove, as an optimization of the diamond saw blade auxiliary fixture of the present utility model, two grooves are opened on the right side wall of the second clamping ring and are distributed vertically. A plurality of springs are installed inside the grooves, and the other ends of the plurality of springs are installed with stoppers slidably connected to the inner side wall of the grooves.

[0011] To facilitate the four limiting rods to pass through the four through holes and move into the four limiting grooves, as an optimization of the diamond saw blade auxiliary fixture of the present utility model, the four limiting rods respectively correspond to the four through holes and the four limiting grooves.

[0012] To facilitate the blocking of the fixing frame, as an optimization of the diamond saw blade auxiliary fixture of the present utility model, the fixing frame is in an upright "U" shape.
