Description

Technical Field

[0001] The utility model belongs to the technical field of grinding wheel dressing devices, in particular to a rotary grinding wheel dressing device for an internal grinding machine. Background Art

[0002] The grinding wheel dressing device is an operating process in which a dressing tool is used to shape the grinding wheel or remove the dull surface to restore the grinding performance and correct geometric shape of the working surface. Timely and correct dressing of the grinding wheel is an important link that is indispensable for improving grinding efficiency and ensuring grinding quality. In the prior art, a moving mechanism is usually set on the grinding wheel dressing transpose so as to move the grinding wheel dressing main body mechanism. However, in this method, the grinding wheel dressing main body mechanism can only be moved in the horizontal direction and cannot be adjusted in the height direction, which may affect the dressing accuracy and cause the size and surface quality of the processed parts to fail to meet the standards.

[0003] For example, the utility model with announcement number CN213999098U discloses a variable frequency internal cylindrical grinder rotary grinding wheel dressing device. In the technical solution of this patent, a moving mechanism and an adjustment component are arranged on the grinding wheel dressing device to adjust the position of the grinding wheel dressing main mechanism. However, in this method, only the horizontal direction of the grinding wheel dressing main mechanism can be moved, and the vertical height cannot be adjusted. During the grinding and dressing process, when the outer circumferential surface, end face or even complex curved surface of the grinding wheel is dressed with high precision, it is often necessary to accurately control the contact point and angle between the dressing tool and the grinding wheel. The lack of vertical height adjustment will affect the dressing accuracy, resulting in the size and surface quality of the processed parts not meeting the standards. Utility Model Content

[0004] In view of this, the utility model aims to provide a rotary grinding wheel dressing device for an internal cylindrical grinder to address the deficiencies in the prior art. The device can not only move the grinding wheel dressing main body mechanism by driving the universal wheel to rotate, but also adjust the height of the grinding wheel dressing main body mechanism through an adjusting component, thereby facilitating precise operation by the staff.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a rotary grinding wheel dressing device for an internal cylindrical grinder includes a base plate, an adjusting component is arranged at the upper end of the base plate, a connecting plate is arranged at the upper end of the adjusting component, and a grinding wheel dressing main body mechanism is arranged at the upper end of the connecting plate.

[0006] As a further improvement of the present invention, the adjustment component includes a mounting seat symmetrically arranged on the base plate, a rotating column is rotatably connected between the two mounting seats, a rotating plate 1 is rotatably connected inside the two mounting seats, the two rotating plates 1 are fixedly connected to the rotating column, the ends of the two rotating plates 1 away from the mounting frame are rotatably connected to rotating plate 2, the other ends of the rotating plate 2 are rotatably connected to fixed blocks, the two fixed blocks are respectively fixedly arranged at the lower ends of the connecting plate, and a driving mechanism for driving the rotating column to rotate is arranged at the upper end of the base plate.

[0007] As a further improvement of the utility model, the driving mechanism includes a support frame arranged at the upper end of the base plate, a worm is arranged at the front end of the support frame, a motor is arranged at the rear end of the support frame, the output end of the motor is connected to the worm through a coupling, and a worm wheel meshing with the worm is arranged at the right end of the rotating column.

[0008] As a further improvement of the utility model, telescopic columns are evenly arranged between the bottom plate and the connecting plate.

[0009] As a further improvement of the utility model, a placement box is provided at the front end of the bottom plate, and a remote control is placed inside the placement box.

[0010] As a further improvement of the utility model, universal wheels are evenly arranged at the lower end of the bottom plate, and foot brakes are arranged on the universal wheels.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] Firstly, by setting the adjustment component, starting the motor can rotate the worm, which drives the worm wheel to rotate, and the worm wheel drives the rotating column to rotate, thereby rotating plate one, and the rotation of rotating plate one drives rotating plate two to rotate, thereby causing the connecting plate to move up and down, and further causing the grinding wheel dressing main body to move up and down, thereby allowing the operator to accurately control the depth of the diamond roller or dressing tool cutting into the grinding wheel, avoiding excessive dressing and causing waste of grinding wheel material, and also ensuring that the effective grinding layer thickness of the grinding wheel after dressing is moderate.

[0013] Secondly, telescopic columns are evenly arranged between the bottom plate and the connecting plate, which disperse the load and allow elastic deformation within a certain range, thereby effectively preventing the main mechanism of the grinding wheel dressing from being damaged due to vibration and other factors and protecting the structure from destruction.

[0014] Thirdly, a placement box is provided at the front end of the bottom plate, and a remote control is placed inside the placement box. The remote control can conveniently control the start and stop of the motor, facilitate remote control by the staff, and ensure the safety of the staff.

[0015] Fourthly, the universal wheels can disperse gravity and reduce the pressure and wear on the ground caused by concentrated loads. It can also facilitate the staff to move the main body of the grinding wheel dressing mechanism. The universal wheels are equipped with foot brakes to ensure that the equipment can be quickly fixed in place after moving, and can be adjusted to a stable state according to the flatness of the ground.
