Disclosure of Invention
The design purpose is as follows: the defects in the background technology are avoided, and the upper abrasive belt and the lower abrasive belt are designed to be driven by the same main motor, so that zero-speed-difference double-sided deburring or single-sided deburring of workpieces between the upper abrasive belt and the lower abrasive belt can be realized, and the deburring of different workpiece thicknesses and the zero-speed-difference synchronous power transmission mechanism and method for the deburring machine double-sided grinding of the brush belt box abrasive head loss compensation can be realized by adjusting the relative distance between the driving spline shaft and the spline sleeve in the driving spline shaft sleeve.
The design scheme is as follows: in order to achieve the above design objective. The invention is mainly characterized in that in structural design, the design of synchronous zero-speed differential double-sided grinding of an upper abrasive belt and a lower abrasive belt in a deburring machine is realized by utilizing a spline pair (namely a driving spline shaft sleeve). The purpose of this design is: because the inner wall of the spline shaft sleeve is designed into the toothed driving wall, the driving spline shaft matched with the toothed driving wall is inserted into the spline shaft sleeve, the driving spline shaft is meshed with the inner wall of the spline shaft sleeve, and the driving spline shaft can extend or retract by taking the wall of the spline shaft sleeve as a guide rail, and the extending amount can be adjusted and locked according to the requirement. Therefore, when the main motor drives the spline shaft sleeve to rotate, the spline shaft sleeve synchronously drives the driving spline shaft positioned in the spline shaft sleeve to rotate at zero speed difference, and as the outer wall of the spline shaft sleeve and the driving spline shaft are respectively sleeved with the driving working belt wheel and the driven working belt wheel, the upper abrasive belt and the lower abrasive belt sleeved on the driving working belt wheel and the driven working belt wheel synchronously deburr the two sides of a workpiece at zero speed difference; when the thickness of the workpiece to be deburred is changed, the deburring device can adapt to the deburring of workpiece surfaces with different thicknesses by only adjusting the interval between the driving spline shaft and the spline shaft sleeve; when the workpiece only needs single-sided deburring, the distance between the driving spline shaft and the spline shaft sleeve is only required to be adjusted, so that the abrasive surface of the abrasive belt driven by the driven working belt wheel is separated from the workpiece surface; when the abrasion of the abrasive head in the abrasive belt cannot form belt pressure contact with the surface to be deburred, the abrasion loss of the abrasive head in the abrasive belt can be compensated by adjusting the extension amount of the driving spline shaft out of the spline shaft sleeve (reducing the extension amount); when the abrasive belt needs to be replaced, the driving spline shaft is separated from the spline shaft sleeve, so that quick belt replacement can be realized, and the belt replacement time is only about 5 minutes.
Technical scheme 1: a zero-speed-difference synchronous power transmission mechanism for double-sided grinding of a deburring machine is characterized in that a driving spline shaft sleeve is arranged on a power shaft of a main motor, the inner wall of the driving spline shaft sleeve is a toothed driving wall, a driving working belt wheel is sleeved on the outer wall of the driving spline shaft sleeve, the driving spline shaft is inserted into the inner wall of the driving spline shaft sleeve and meshed with the toothed driving wall of the inner wall of the driving spline shaft sleeve, a driven working belt wheel is arranged on the driving spline shaft exposed out of the driving spline shaft sleeve, and an upper abrasive belt and a lower abrasive belt are respectively sleeved on the driving working belt wheel and the driven working belt wheel.
Technical scheme 2: a zero-speed-difference deburring method for a zero-speed-difference synchronous power transmission mechanism of a deburring machine comprises the steps that a main motor shaft drives a driving spline shaft sleeve and a driving working belt pulley sleeved on the outer wall of the driving spline shaft sleeve to rotate, and simultaneously, the driving spline shaft sleeve synchronously drives a driving spline shaft inserted into the inner wall of the driving spline shaft sleeve and a driven working belt pulley sleeved on the driving spline shaft to rotate, so that an upper brush belt box and a lower brush belt box move in the same direction at the same speed relative to each other, and when a workpiece to be deburred passes through the upper brush belt box and the lower brush belt box, deburring heads of the upper brush belt box and the lower brush belt box grind the workpiece in double sides.
Compared with the background technology, the invention realizes that the upper abrasive belt and the lower abrasive belt are synchronously driven to respectively rotate in a plane by one motor at zero speed difference, so that workpieces passing between the upper abrasive belt and the lower abrasive belt are double-sided deburred; secondly, the double-sided deburring or single-sided deburring can be suitable for workpieces with different thicknesses; thirdly, the abrasion loss of the abrasive head on the abrasive belt is compensated by adjusting the expansion and contraction quantity of the driving spline shaft; fourth, achieve the goal of changing the abrasive belt rapidly; fifth, the structure is simple and reliable, and the manufacturing cost is low.
