Description

Technical Field

[0001] The present invention relates to the technical field of grinding devices, in particular to a grinding device for processing steel parts of buildings. Background Art

[0002] During the construction of a house, a grinding device is usually used to grind the steel bars to ensure their connection strength, dimensional accuracy, and structural support safety. During the long-term use of the grinding device, due to the presence of a hardened layer on the surface of the steel bar, the abrasive wear mechanism changes from plastic cutting to brittle spalling, causing wear of the grinding wheel. When the diameter of the grinding wheel is worn to two-thirds of its original size, the grinding wheel needs to be replaced in a timely manner to ensure the grinding efficiency and accuracy of the steel bar.

[0003] For example, the existing application number CN202411852260.1 discloses a reinforced concrete component grinding device, which grinds the remaining original protruding part of the main steel bar so that the remaining original protruding part of the main steel bar is exposed outside the concrete part of the reinforced concrete component, so that the reinforced concrete component can be connected to other reinforced concrete components again through the main steel bar of this part, thereby realizing the reuse of the reinforced concrete component; this invention is applied to the field of reuse of concrete components.

[0004] However, in the actual application of the grinding device, when the grinding wheel diameter is worn to the specified position, it is very easy for the operator to continue to use it without replacing it in time due to weak maintenance awareness or the fluke mentality of prioritizing production progress, as well as the construction unit's control of costs. Not only is it easy for the grinding wheel to break due to the decrease in edge strength, resulting in safety accidents, but it is also easy for the reduction in grinding wheel diameter to lead to calculation deviations in grinding feed, resulting in loss of control of steel bar size accuracy, and due to the blunting of the grinding wheel abrasive particles, the roughness of the steel bar surface is aggravated, causing the surface integrity of the steel bar to be destroyed, resulting in greater safety hazards in the later use of the steel bar. Summary of the Invention

[0005] In view of this, the present invention provides a grinding device for processing steel parts for building houses. When in use, the detection pillar is in real-time contact with the surface of the grinding wheel. When the diameter of the grinding wheel is worn to two-thirds of its original size, the detection pillar moves upward as the outer diameter of the grinding wheel is reduced. The force exerted by the upward movement of the detection pillar is used to push the positioning support block to accurately insert into the positioning guide groove, forcibly locking the grinding wheel spindle, avoiding excessive wear caused by manual misjudgment, greatly avoiding the grinding wheel breakage caused by the reduction of the edge strength of the grinding wheel, and the deviation in the calculation of the grinding feed amount due to the reduction of the grinding wheel diameter, which causes the steel bar dimensional accuracy to be out of control, thereby improving the grinding of steel bars. The production safety during cutting and the grinding accuracy of the steel bars ensure the surface integrity of the steel bars, further improving the safety of the steel bars in later use, as well as the work efficiency and use effect of the device in actual application; at the same time, the elastic support shaft and the elastic pillar are used to form a double elastic support structure. When the diameter of the steel bar fluctuates or the surface is uneven, the radial displacement of the steel bar is automatically compensated, so that the grinding wheel and the steel bar always maintain a constant grinding pressure, avoiding the deterioration of the steel bar surface roughness caused by pressure fluctuations, further improving the grinding effect of the steel bar and the safety of the steel bar in subsequent use; the present invention constructs a full-process quality control system for construction steel bar grinding processing through the systematic design of "wear detection-mechanical locking-elastic tensioning-quick change structure", which not only fundamentally solves the safety and quality risks caused by excessive wear of the grinding wheel, but also improves the processing efficiency, accuracy and equipment reliability to a new level through automation technology, providing a standardized solution for the precision processing of steel bars in building industrialization, with significant engineering application value and economic benefits.

[0041] Among them, the detection auxiliary mechanism also includes: a positioning support block 702, which is a polygonal block structure, and the left and right ends of the positioning support block 702 are elastically connected to the movable bracket 6; a polygonal positioning guide groove 703 is provided at the alignment position of the right end positioning support shaft 4 and the positioning support block 702.

[0042] Among them, the detection auxiliary mechanism also includes: a driving gear 704, a transmission rack 705 and a transmission gear 706.
