Shot blasting machine with connection shafts and support bearings

Abstract

The invention provides a shot blasting machine with connection shafts and support bearings. The shot blasting machine comprises the connection shafts and the support bearings. One end of a connection shaft is fixedly connected to the sliding door, the other end is connected to a support bearing, and the shaft length of a connection shaft is less than one third of the width of the sliding door; the support bearing comprises two bearings which are connected in series connection. Shortened connection shafts increase rigid and stability, support bearings employ duplex bearing, so that stability and bearing capability of the sliding door during a motion process are improved. The shot blasting machine with connection shafts and support bearings has the beneficial effects of simple structure, skillful design, high carrying capacity, high safety, etc.

Description

technical field [0001] The invention relates to a shot blasting machine, in particular to a shot blasting machine with a connecting shaft and a supporting bearing. Background technique [0002] With the development of science and technology, the current shot blasting machines are gradually adopting new technologies. In the past, the shot blasting doors were closed and opened manually. Now, various methods such as hydraulic pressure and air pressure are used to open and close the doors semi-automatically. When using the cylinder type to open and close the door, usually the sliding door is directly lifted up vertically, which may cause the weight of the sliding door to be heavy, and a single cylinder is not enough to pull it up directly, and two cylinders are required or more cylinders can be operated, which greatly increases the cost.

AI Technical Summary

Problems solved by technology

When using the cylinder type to open and close the door, usually the sliding door is directly lifted up vertically, which may cause the weight of the sliding door to be heavy, and a single cylinder is not enough to pull it up directly, and two cylinders are required or more cylinders can be operated, which greatly increases the cost

[0003] Moreover, because the cylinder is connected to the sliding door at a single point, when the cylinder pulls the sliding door, it is easy to cause the sliding door to be unbalanced, causing a corner of the sliding door to tilt and get stuck on the shot blasting machine, so that the cylinder can no longer pull the sliding door. cause damage

[0004] In addition, the shaft length of the previous connecting shaft exceeds half the width of the sliding door. When the sliding door is stuck, a huge force acts on it, which can easily cause damage or even damage to the connecting shaft.

Moreover, the supporting bearings connected to the connecting shaft are all single bearings, and the width of the bearing is smaller than the width of the side in contact with the shot blasting machine, which is likely to cause the overall shaking and make the sliding door stuck

[0005] In addition, the current cylinder type semi-automatic switch door has only two states of open or closed stroke control, that is, it cannot stop working when the switch is opened, and there is no half-open state. A trip, a waste of electricity, and a waste of time
