Abstract

The Roller Grinding Machine is an invention of industrial application for the grinding and mechanical finishing of raceways for trompels. The contact surface deteriorates due to operation. That is why the rotating elements deteriorate, deforming and wear. This leads to vibration and malfunction. This implies an increase in the consumption of maintenance materials. This element is developed to work in situ and therefore eliminate the need to disassemble the raceways and transfer them to specialized workshops in the machining and repair of this type of elements. The work carried out in situ by the grinding machine allows saving direct costs to repair the raceways and also saves time. This is due to the fact that since the work is carried out in situ, there will be no need to hire transfer, elevation and transport elements.

Description

DESCRIPTION

Grinding grinder.

Technical sector

The invention falls within the sector of the rectification of tread rings.

Background of the invention

This invention arises as a result of the need to maintain a correct surface finish in the treads of the trommels.

The treads serve to transmit the rotary movement to the trommel. And these need to have a correct mechanical finish.

Treadings or treads are industrial parts, usually large, that find functionality in many machines. Rotating bodies sit on them, to achieve a regular and balanced rotational movement.

Until now, the grinding process carried out in the industry entails a high cost, both direct and indirect, due to the labor and machinery necessary to rectify this type of parts.

Explanation of the invention.

Following these difficulties, the solutions described below are proposed.

We start from grinding procedures using machinery not available for on-site work.

The present invention materializes a rolling grinding machine, consisting of a vessel which incorporates a grinding stone that fits tangentially to the rolling by means of two auxiliary clamping arms. Said set of stone and auxiliary arms is adapted to a multitude of circumference arches to perform a homogeneous grinding, thus improving the setting of the tread and the relationship between the time spent and the quality of the finish obtained.

The machinery has regulation points, both angular and linear, by means of actuating steering wheels for the correct adjustment of the grinding stone and the arms of subjection to the rolling.

On the other hand, the machinery also has pneumatic pressure regulation system to maintain the level of grinding on rolling.

These clamping points are distributed so that the grinding stone acts in a central position with respect to them. These are located above and below the first, adapting to the rolling diameter thanks to the aforementioned regulation possibility.

The choice of the abrasive as a material for the rectification, achieves a cylindrical machining effect of the surface imperfections that the rolling presents.

Said translation mechanism could be a rack-and-pinion mechanism driven by a double reduction box-electric motor.

Figure 7-13-15-19-10-11 are the points of regulation-multiple articulation, on which said machinery is based to achieve a correct attack of the grinding piece on the piece to be rectified, being able to adapt to multiple arcs, because the support arms are provided with a spindle-flywheel approach system with tip rocker for fit the radius of the horseshoe. And perform grinding while maintaining the force with the built-in pneumatic system, by means of a flow and pressure regulator.

The drive shaft drive system for the grinding stone is made using a tension system: toothed belt pulley and floating motor, to reduce the space as much as possible, facilitating a better positioning of the machine.
