DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figure 1-3The utility model provides a technical solution: a gear grinding machine for circular saw blades, comprising an operating table 100, on which a grinding assembly 500 for grinding circular saw blades is installed, a dust suppression assembly 200 for preventing dust generated when grinding the circular saw blades from scattering, and a dust removal assembly 300 for removing dust generated when grinding the circular saw blades are installed, and the dust removal assembly 300 is connected to a negative pressure assembly 400;

[0024] The dust removal assembly 300 includes a dust suction groove 301, which is designed in a U-shaped shape and is embedded in the operating table 100. The bottom of the dust suction groove 301 is in a rectangular array and is connected to a dust suction pipe 302. One end of the dust suction pipe 302 passes through the operating table 100 and is connected to a filter cabinet 303.

[0025] When in use, the negative pressure assembly 400 operates to generate suction in the dust suction groove 301, so that the dust generated when grinding the circular saw blade is sucked into the dust suction groove 301, and then intercepted by the filter layer 305 in the filter cabinet 303. Regularly cleaning the filter cabinet 303 can ensure the cleanliness of the cutting environment and prevent dust from affecting the normal grinding operation.

[0026] When cutting and grinding a circular saw blade, the dust removal component 300 and the negative pressure component 400 cooperate to collect the dust generated when grinding the circular saw blade, and the dust suppression component 200 prevents the dust generated when grinding the circular saw blade from flying around, thereby preventing the dust from contaminating the relevant parts and workpieces on the machine tool and affecting the normal grinding of the circular saw blade, thereby improving the practicality of the device.
