Description

Technical Field

[0001] This utility model relates to the field of internal grinding machine technology, specifically an internal grinding machine with end face grinding. Background Technology

[0002] An internal grinding machine is a machining and manufacturing machine used to grind the inner surface and end face of cylindrical, conical or other shaped generatrices. Currently, the widely used internal grinding machines include an internal grinding machine body, which is equipped with a fixed frame and a grinding mechanism.

[0003] According to the prior art, an internal grinding machine (authorization announcement number: CN 214519211 U) is described as follows: "This utility model relates to an internal grinding machine, including an internal grinding machine body, a fixed frame and a grinding mechanism on the internal grinding machine body, the grinding mechanism including a grinding wheel, the fixed frame located on the left side of the upper surface of the internal grinding machine body, the grinding mechanism located on the right side of the upper surface of the internal grinding machine body, a protective cover on the outside of the fixed frame, an opening for workpiece installation at the front end of the protective cover, a protective door slidably provided on the front side of the protective cover, a liquid storage tank in the internal grinding machine body, a plurality of drain holes on the upper surface of the internal grinding machine body and the plurality of drain holes located directly above the liquid storage tank, a cooling chamber outside the grinding mechanism, a water outlet and a water inlet on the upper and lower surfaces of the cooling chamber respectively, the water inlet being connected to the liquid storage tank through a connecting pipe, a liquid pump connected in series on the connecting pipe, a spray head connected to the water outlet, and a protective component on the outside of the grinding wheel. Compared with the prior art, this utility model improves production efficiency and reduces safety hazards in the production process."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In use, this utility model places the space on the fixed frame through the opening at the front of the protective cover, and then slides the protective door to the right. The sliding block and the sliding groove cooperate to facilitate the movement of the protective door by the staff. In actual use, because the position of the spray head of this device is fixed, it cannot effectively suppress the dust generated during processing. At the same time, the processing of this device only completes the grinding of the inside of the workpiece, which affects the subsequent grinding of the end face of the workpiece and thus affects the perpendicularity. Therefore, it is necessary to improve the internal cylindrical grinding machine with end face grinding to solve the above problems. Utility Model Content
