Description

Technical Field

[0001] The utility model relates to the technical field of saw blade production, and particularly relates to a tooth deburring mechanism. Background Art

[0002] When manufacturing a saw blade, burrs or irregular edges may appear on the teeth, which may affect the cutting effect and service life of the saw blade. To remove these burrs, special deburring equipment or processes are usually used to process the teeth of the saw blade to ensure its cutting effect and safety.

[0003] The previous deburring mechanisms can only perform deburring operations on a single saw blade tooth during work, resulting in low work efficiency. Summary of the Invention

[0004] Aiming at the problems in the prior art, the utility model provides a tooth deburring mechanism, which can perform deburring operations on two groups of saw blade teeth simultaneously, greatly improving the work efficiency.

[0005] The technical solution adopted by the utility model to solve its technical problems is a tooth deburring mechanism, which includes a bottom plate, a thickening plate, a first mounting seat, a servo motor, a driven shaft, an annular grinding wheel and a sleeve shaft. One end of the top of the bottom plate is installed with a first mounting seat through bolts, and a servo motor is installed on one side of the first mounting seat through bolts. The power output end of the servo motor is connected with a keyed output shaft, and a driving gear is sleeved outside the keyed output shaft. A key is arranged on the driven shaft, and a driven gear meshing with the driving gear is clamped on the driven shaft near the key;

[0006] Convex discs are arranged at both ends of the driven shaft, grooves are formed on one side of the convex discs, a flange is arranged on the periphery of the end of the sleeve shaft, and the flange is fixedly connected with the groove through a tapered countersunk head bolt. A threaded hole is formed at the other end of the sleeve shaft, a circular limiting plate is fixed on one side of the threaded hole through a bolt, and an annular grinding wheel is sleeved outside the sleeve shaft.

[0007] By adopting the above technical solution, when the servo motor works, it drives the driven shaft to rotate. When the driven shaft rotates, it drives the two groups of convex discs, sleeve shafts and annular grinding wheels located at the ends to rotate. This deburring mechanism can perform deburring operations on two groups of saw blade teeth simultaneously, greatly improving the work efficiency.

[0008] Specifically, second mounting seats are fixed on both sides of the other end of the top of the bottom plate far away from the first mounting seat through bolts, and bearing seats are installed on one side close to each other of the two second mounting seats through bolts.

[0009] Specifically, bearings are arranged in the bearing seats, and the driven shaft is located in the bearings.

[0010] Specifically, cylindrical countersunk holes are provided at the top of the bottom plate near the corners.

[0011] By adopting the above technical solution, the bottom plate can be conveniently fixed and installed by passing an external bolt through the cylindrical countersunk hole, so as to facilitate the fixed installation of this deburring mechanism.

[0012] Specifically, thickening plates are provided at the bottom of the bottom plate at positions corresponding to the cylindrical countersunk holes.

[0013] Specifically, spray-coated corrosion-resistant layers are provided on the outer surfaces of the bottom plate, the first mounting seat, the second mounting seat and the third mounting seat.

[0014] By adopting the above technical solution, the corrosion-resistant effect of the outer surfaces of the bottom plate, the first mounting seat, the second mounting seat and the third mounting seat can be effectively improved through the spray-coated corrosion-resistant layer, which is beneficial to improving the service life.

[0015] Advantages of the present utility model:

This deburring mechanism can simultaneously perform deburring operations on the tooth teeth of the two groups of saw blades, greatly improving the working efficiency.

A flange 16 is provided on the outer periphery of the end of the sleeve shaft 19. The flange 16 is fixedly connected with the groove 15 by tapered countersunk bolts. A threaded hole 20 is opened at the other end of the sleeve shaft 19. A circular limiting plate 17 is fixed by bolts on one side of the threaded hole 20. An annular grinding wheel 18 is sleeved outside the sleeve shaft 19.

[0025] During use, when the servo motor 5 works, it drives the driven shaft 11 to rotate. When the driven shaft 11 rotates, it drives the two groups of convex discs 14, sleeve shafts 19 and annular grinding wheels 18 located at the ends to rotate. This deburring mechanism can simultaneously perform deburring operations on the tooth flanks of two groups of saw blades, and the working efficiency is greatly improved.
