Description
Technical Field
[0001] The utility model relates to the technical field of guardrail grinding, in particular to a high-precision grinding device for guardrail manufacturing. Background Art
[0002] Guardrails are widely installed in roads, bridges, residences, commercial areas, public places, such as on both sides of logistics channels, around production equipment, building walls, both sides of doors and the edge of cargo platforms, etc. They are mainly used to protect personal safety and equipment facilities. Guardrails are usually made of steel, such as stainless steel, round steel pipes, square steel pipes or corrugated steel plates.
[0003] During the manufacturing process of the guardrail, the connecting ends of the guardrail rods need to be polished to make the guardrail rods easy to assemble and avoid scratching the hands of the assemblers.
[0004] Guardrails are usually polished by workers manually pressing down on them. During the polishing process, the guardrails are squeezed by the grinder and are prone to shaking, which causes the polished parts to be tilted and irregular. During the polishing process, the guardrails are squeezed by the grinder and are prone to shaking, which causes the polished parts to be tilted and irregular. Since the guardrails need to be polished on both sides, they need to be manually turned over, and due to the large size of the guardrails, the turning process is difficult for one person to complete, which results in inconvenience in polishing. Traditional grinders will generate high temperatures when they come into contact with the surface of the guardrail during the polishing process, which can easily scald workers. In addition, the temperature of the grinder blade and the guardrail is too high, which is not convenient for subsequent polishing and affects work efficiency. Utility Model Content

[0030] Example 2
[0031] Reference Figure 1-4 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: a heat dissipation component 5 that can dissipate heat when grinding the guardrail is provided on the other side of the operating table 1. The heat dissipation component 5 includes an air pump 51 installed on one side of the operating table 1. A No. 1 air delivery pipe 52 is installed on the top of the air pump 51. A No. 2 air delivery pipe 53 is installed at one end of the No. 1 air delivery pipe 52. The No. 1 air delivery pipe 52 and the No. 2 air delivery pipe 53 are used to transport gas.

[0033] The working process of the utility model is as follows:
[0034] The No. 1 hydraulic rod 32 reciprocates to drive the fixed block 33 and the No. 1 rack 34 to move, and at the same time, the meshing drives the gear 35 to rotate and mesh with the No. 2 rack 36.

[0035] The first gas pipeline 52 and the second gas pipeline 53 transport the gas generated in the gas pump 51, and finally dissipate the heat and cool the surface of the grinder and the guardrail through the heat dissipation holes 54, so as to avoid the surface temperature of the grinder and the guardrail being too high and inconvenient for subsequent use, and to avoid scalding the hands of the staff;
[0036] The lifting plate 41 is pushed by the No. 2 cylinder 39 to rise and fall and slide in the fixed plate 38. The height of the lifting plate 41 in the fixed plate 38 can be adjusted according to the size of the guardrail. Then the worker rotates the guardrail, and then the turntable 7 rotates to turn the guardrail over, which solves the inconvenience of manual turning over, and the turning time is too short, and the grinding efficiency is higher.
[0037] After the guardrail is fixed in position, the grinder 2 placed on the workbench is manually picked up and evenly moved on the surface of the guardrail. After the grinding is completed, the grinder is put back to its original position.
[0038] The remaining structures are the same as those of Example 1.
