Description

  The present invention relates to a simultaneous polishing machine for polishing a rotating surface in the center of one shaft, for example a camshaft or crankshaft bearing or journal.
From Patent Document 1, a polishing machine having a polishing disk set for simultaneously polishing a large number of bearing portions of a crankshaft is known.
In this case, an individual polishing disk is provided for polishing the support element seat on the other side of the crankshaft, positioned relative to the polishing disk set. Thus, additionally, one support element seat is ground.
After this finishing, the individual abrasive disc is retracted and the support element is abutted. Subsequently, the bearing portion is polished to a completed state with a polishing disk set.
German patent application specification DE 10 2009 024 209 A1
  The object of the present invention is therefore to develop a polishing machine of the type described at the outset, which reduces the processing time for the processing material compared to the prior art.
  This problem is solved by a polishing machine having the features of claim 1. Advantageous embodiments are the subject matter of the dependent claims.
In accordance with an advantageous aspect of the present invention, the rotating surface to be polished is distributed between two polishing disk sets, and these polishing disk sets are provided on oppositely positioned sides of the shaft, and therefore The normal force components of these polishing forces acting on this axis cancel each other.
In addition, a support element is provided, which, during polishing, together with the abrasive disc set is sent to the work material (zugestellt) and a cutting force acting on the work material in the tangential direction ( Zerspankraefte) is housed. In doing so, no Sitze need be pre-polished for this support element.
  Next, the present invention will be described in detail based on examples.
It is a figure of the simultaneous grinder of this invention. It is a figure of arrangement | positioning of an abrasive disc set. It is a figure of arrangement | positioning of an abrasive disc set. It is a figure of arrangement | positioning of an abrasive disc set. It is a figure of arrangement | positioning of an abrasive disc set. FIG. 6 is a diagram of the arrangement with the support element.
The simultaneous polishing machine according to FIG. 1 has a work material spindle 1 and a push table 2 for clamping and driving at the center of a shaft (work material) 3. For the machining of these shafts 3, two grinding spindle stands 6, 6 'are provided. These polishing spindle tables are movable on the guide device 8 via horizontal moving tables 5, 5 ′ and vertical moving tables 4, 4 ′ in the machine frame 7.
These polishing spindle stands 6, 6 'are fed to this shaft 3 in the opposite direction in the X-axis direction, and thus the normal force of these polishing forces acting radially on this shaft 3 The components cancel each other out.
The vertical movement tables 4 and 4 ′ are driven in the Z direction through a ball roller spindle and a motor 9. Similarly, the work material spindle 1 is also provided in the machine frame so as to be movable via a motor 9 '.
In FIG. 1, a crankshaft 3 is shown as the shaft 3.
This crankshaft is simultaneously machined with two abrasive disc sets 10, 10 '.
Both of these abrasive disc sets 10, 10 ′ are each composed of a number of individual abrasive discs 13. Thus, all of the central rotating surface 12 to be polished can be polished to a finished state within a single processing step.
In the case of the crankshaft 3 shown here, the intermediate bearing portion, the journal 15, and the flange outer peripheral surface 16 are specific. In this case, the width of the individual polishing disks 13 and the distance between the individual polishing disks are adapted to the distance and dimensions of the rotating surface 12 on the crankshaft.
Despite the staggered misalignment of the abrasive disc set 10, 10 'in the direction of the spindle axis 14, 14', this deflection of the shaft 3 is negligible. because,
This is because the polishing disk sets 10 and 10 'act on the shaft 3 on the side where they are positioned relative to each other.
The same effect can be reinforced by the provision of a greater number of individual abrasive discs 13 for the extremely bend-sensitive shaft 3 than the rotating surface 12 to be machined.
FIG. 2 relates to an arrangement according to claim 3. Here, approximately in the middle of the shaft 3, the two individual polishing disks 13, 13 ′ are simultaneously engaged on one rotating surface 12.
FIG. 3 shows an arrangement according to claim 4, in which two individual abrasive discs 13, 13 ′ are simultaneously engaged on the two rotating surfaces 12.
In FIGS. 4 and 5, the machining of the camshaft is illustrated.
FIG. 4 corresponds to the features of claim 5, in which two individual abrasive discs 13, 13 ′ are engaged simultaneously on all rotating surfaces 12 of the shaft 3. In short, FIG. 5 illustrates an arrangement according to claim 6.
In FIG. 6, the arrangement of the support elements 17 is illustrated.
This support element is simultaneously fed with the individual abrasive discs 13, 13 ′ during polishing, whereby the cutting forces acting on the workpiece in the tangential direction are offset (kompensiert). This support element 17 is fed in the Y direction while these individual abrasive discs 13, 13 'are fed in the opposite direction, in the X-axis direction.
