Therefore, a stable type gear grinding machine with convenient oiling is proposed. Summary of the Utility Model

[0004] The purpose of the present utility model is to solve the problem that during the use of the stable type gear grinding machine, it is necessary to often apply lubricating oil on the main shaft to ensure the normal operation of the gear grinding machine. However, when applying lubricating oil to the existing stable type gear grinding machine, it is necessary to remove the grinding wheel for application or spray oil onto the main shaft through a long-gun type lubricating oil spray can, which makes the oiling process inconvenient, and it is impossible to oil during the continuous operation of the gear grinding machine, and there is a risk of spraying obliquely. The present utility model provides a stable type gear grinding machine with convenient oiling.

[0005] The present utility model specifically adopts the following technical solutions to achieve the above purpose:

[0006] A stable type gear grinding machine for a grinding wheel that facilitates oiling, comprising a base, a protective housing is installed on the base, a rotating shaft is rotatably installed on the protective housing, a grinding wheel is movably installed on the rotating shaft, a placement table is installed on the base, a contact mechanism for contacting the rotating shaft to release lubricating oil is installed on the protective housing, a dropping mechanism for supplying lubricating oil to the contact mechanism assembly is installed on the contact mechanism, and a braking mechanism for pumping out the lubricating oil is installed on the dropping mechanism. When adding lubricating oil to the gear grinding machine for the grinding wheel, the contact mechanism assembly is pulled to contact the rotating shaft. During this process, the braking mechanism moves to pump the lubricating oil through the dropping mechanism into the contact mechanism assembly, so that continuous lubrication can be carried out when the gear grinding machine for the grinding wheel is working, improving the convenience and practicality of oiling.

[0007] Further, the contact mechanism includes a sliding shaft, the sliding shaft is installed on the protective housing, a sliding block is slidably installed on the sliding shaft, a rotating plate is rotatably installed on the sliding block, a pulling plate is rotatably installed on the rotating plate, an L-shaped braking plate is installed on the pulling plate, the L-shaped braking plate is slidably installed on the protective housing, an arc-end block is installed on the sliding block, the arc-end block is located on both sides of the rotating shaft. By pulling the L-shaped braking plate, the movement of the L-shaped braking plate drives the pulling plate to slide, the sliding of the pulling plate drives the two rotating plates to slide closer to each other, the sliding closer of the rotating plates drives the sliding block to slide closer to each other on the sliding shaft, and the sliding closer of the sliding blocks drives the arc-end blocks to slide closer to each other to contact the grinding wheel.

[0008] Further, a return spring is movably sleeved on the sliding shaft, one end of the return spring is installed on the sliding block, and the other end of the return spring is installed on the protective housing. Through the setting of the return spring, after the L-shaped braking plate is released, the structure is driven to reset under the reset elastic force of the return spring, improving the convenience and practicality of the structure.

[0009] Further, a T-shaped sliding groove is opened on the protective housing, a T-shaped block is installed on the pulling plate, and the T-shaped block is slidably installed in the T-shaped sliding groove. The T-shaped sliding groove restricts the movement of the T-shaped block, and the T-shaped block can only slide in the T-shaped sliding groove, so that the pulling plate can only slide on the protective housing.

[0010] Further, the liquid dropping mechanism includes a lubricating oil tank installed on the protective shell. A connecting hose is installed on the lubricating oil tank and is mounted on the arc-end block. A cavity is formed in the arc-end block, and the connecting hose communicates with the cavity. A spherical groove is formed in the arc-end block, and a movable ball plug is movably installed in the spherical groove. An installation groove is formed in the arc-end block, and a compression spring is movably installed in the installation groove. One end of the compression spring is installed on the arc-end block, and the other end of the compression spring contacts the movable ball plug. The lubricating oil in the lubricating oil tank flows into the cavity on the arc-end block through the connecting hose when pumped out. When the arc-end block contacts the rotating shaft, the movable ball plug slides in the spherical groove to open the spherical groove, facilitating the outflow of the lubricating oil. After the arc-end block moves away from the rotating shaft, the compression spring drives the movable ball plug to fall back into the spherical groove under the reset elastic force to prevent the lubricating oil from flowing out, thus completing the oiling process.

[0011] Further, a limit seat is installed on the protective shell, and the connecting hose is movably installed on the limit seat. Through the setting of the limit seat, it is prevented from touching the connecting hose during the rotation of the grinding wheel, improving the safety and practicality of the structure.

[0012] Further, the braking mechanism includes a fixed ring installed on the protective shell. The connecting hose is installed on the fixed ring. A limit rotating shaft is installed on the protective shell, and a gear block is rotatably installed on the limit rotating shaft. An arc-end pressing block is installed on the gear block and contacts the connecting hose. Continuous teeth are installed on the L-shaped braking plate and mesh with the gear block. When the L-shaped braking plate is pulled, the continuous teeth drive the gear block to rotate on the limit rotating shaft. During the rotation of the gear block, the two ends of the arc-end pressing block squeeze the connecting hose on the fixed ring, thereby realizing pumping the lubricating oil in the lubricating oil tank into the cavity formed in the arc-end block, further improving the use convenience of the structure.

[0013] The beneficial effects of the present utility model are as follows:

In the present utility model, through the settings of the arc-end block, movable ball plug, arc-end pressing block, etc., when lubricating oil needs to be applied, by pulling the L-shaped braking plate to drive the arc-end blocks on both sides to contact the rotating shaft. During this process, the arc-end pressing block is automatically driven to rotate to pump the lubricating oil in the lubricating oil tank into the arc-end block, and by squeezing the movable ball plug to open the spherical groove, the oiling process can be completed, realizing oiling during the operation of the stable type gear grinding machine, improving the use convenience and practicality of the equipment.

[0015] 2. In the present utility model, through the setting of the limit seat, it is prevented from touching the connecting hose during the rotation of the grinding wheel, improving the safety and practicality of the structure.

[0016] 3. In the present utility model, through the setting of the reset spring, after the L-shaped braking plate is released, the structure is driven to reset under the reset elastic force of the reset spring, improving the use convenience and practicality of the structure.
