Description

Grinder grinding disc lifting device

Technical field:

The utility model relates to a grinding machine, in particular to a grinding disc lifting device of the grinding machine.

Background technique:

Existing grinding machines generally use a cylinder to lift the grinding disc. Due to the existence of sliding, this kind of lifting mechanism consumes a lot of energy and is difficult to lift and position.

Invention content:

The purpose of the utility model is to provide a grinding disc lifting device with accurate positioning.

The utility model realizes the purpose of the invention by adopting the following technical scheme, a grinding machine grinding disc lifting device, which includes a lower grinding disc, the lower grinding disc is installed on the lifting workbench, and left and right fixed pulleys are arranged on the lifting workbench, and on the frame There are left and right chute for sliding of left and right wedge-shaped sliders, and left and right rolling grooves for left and right fixed pulleys rolling and left and right chute for moving left and right sliders are arranged on left and right sliders. hydraulic cylinder.

Due to the adoption of the above-mentioned technical scheme, the utility model better realizes the purpose of the invention. Its structure is simple, and two hydraulic cylinders and wedge-shaped sliders are used to realize accurate positioning of lifting, reduce energy consumption, and increase the pressure of grinding. .

Description of drawings:

Fig. 1 is a structural representation of the utility model;

Fig. 2 is a top view of the frame part in Fig. 1 .

Detailed ways:

Below in conjunction with accompanying drawing, the utility model is further described.

It can be seen from Fig. 1 and Fig. 2 that a grinding disc lifting device for a grinding machine includes a lower grinding disc 6, which is installed on a lifting workbench 8, and left and right fixed pulleys 3 and 9 are arranged on the lifting workbench 8, and the frame 16 is provided with the left and right chute 13,14 that is used for left and right wedge-shaped slide block 2,10 slides, and left and right slide block 2,10 is provided with the left and right that is used for left and right fixed pulley 3,9 rolling. Roll grooves 12, 15 and left and right hydraulic cylinders 1, 11 for moving left and right sliders 2, 10.

The grinding machine also includes an upper grinding disc 4, a vertical shaft 7 and other components. The workpiece 5 is placed between the upper grinding disc 4 and the lower grinding disc 6. When the upper grinding disc 4 and the lower grinding disc 6 move relative to each other, the grinding process of the workpiece 5 can be realized. .

When the utility model needs to adjust the lower grinding disc 6, when the left and right hydraulic cylinders 1 and 11 are driven to move the left and right wedge-shaped sliders 2 and 10 to the middle, the left and right fixed pulleys 3 and 9 are respectively in the left and right chute 12 , 15 slide, move to the high end of left and right wedge-shaped sliders 2, 10, thereby lifting workbench 8, and then lift lower grinding disc 6; When driving left and right hydraulic cylinder 1, 11 makes left and right wedge-shaped sliders 2, When 10 moves to the left and right ends, the left and right fixed pulleys 3 and 9 slide in the left and right chutes 12 and 15 respectively, and move to the low end of the left and right wedge-shaped sliders 2 and 10. Other components descend under the action of pressure, and then drive the lower grinding disc 6 to descend.
