Definitions

  • the invention relates to a high-speed honing machine according to the preamble of patent claim 1.
  • the honing tool In known honing machines, the honing tool is rotationally driven, introduced into the bore to be machined and reciprocated in the longitudinal direction of the bore. This results in a cross-cut or a sine cut on the inner surface of the hole.
  • the speed and the oscillation speed must be exactly matched. Since the honing tool is clamped in a tool spindle, it must also be driven in an oscillating manner, including the rotational drive of the spindle.
  • the masses to be moved are relatively large, so that an increase in the oscillation speed and thus the speed of the honing tool are limited.
  • the present invention has for its object to provide a honing machine, with even higher processing speeds than with the known honing machine are possible.
  • the tool spindle is not driven in an oscillating manner with the honing tool, but the workpiece carrier with the tool, which as a rule has a significantly lower mass than the tool spindle with its drive device and the honing tool.
  • significantly higher oscillation speeds can be achieved for the workpiece carrier with the tool than for the honing tool in honing machines with a stationary tool carrier. Due to the higher oscillation speeds, the speed of the honing tool can be increased compared to the state-of-the-art machines, resulting in significantly shorter machining times for the workpieces.
  • the use of a linear motor for driving the workpiece carrier has the advantage that can be dispensed with transmission and high accelerations are achievable.
  • the honing machine according to the invention has the further advantage that a relatively fine machining of the bore surface is possible by the higher possible speeds with a relatively coarse friction lining of the honing tool, so that less different honing tools must be used for machining the bore. In addition to the savings Tool costs are thereby achievable further shortening of the machining time of the workpiece.
  • the workpiece carrier is arranged on a slide connected to the rotor of the linear motor.
  • the carriage can be relatively low friction, for example, lead to a rail assembly on the machine, which additionally increases the achievable speeds.
  • Carriage and rotor of the linear motor can also be integrally formed, d. H. the carriage can form the rotor of the linear motor. The masses to be moved can thereby be further reduced.
  • the tool spindle is arranged relative to the workpiece carrier adjustable. In this way, the space between the tool spindle and the workpiece carrier can be shortened or lengthened, so that workpieces of different heights can be processed with the honing machine without the use of tool extensions.
  • the conversion of the machine to different workpieces is also extremely simple.
  • the tool spindle can also be made to oscillate drivable.
  • the oscillatory movements of the workpiece carrier and the tool spindle can then be superimposed in such a way that once again an increase in the speed of the honing tool is possible in order to be able to move on Inside the machined hole to create the desired microsection.
  • the tool spindle can be arranged on a carriage which can be driven by means of a linear drive.
  • a linear drive in addition to a linear motor in principle also hydraulic or pneumatic cylinders or screw drives in question.
  • a control device can also be provided on the honing machine with which the oscillation movement executable by the workpiece carrier and the rotational speed of the tool spindle can be matched to one another, so that the desired grinding is formed on the workpiece and operating errors are virtually ruled out.
  • the oscillating movements of the workpiece carrier and the tool spindle can be matched or synchronized by means of the control device.
  • the control device also facilitates setting the machine to new honing tasks.
  • the tool spindle can have a hydraulic chuck with an internal coolant supply.
  • Hydraulic chucks provide hydraulic vibration damping of the tensioned tool. Due to the higher concentricity of the tools higher service life for these can be achieved.
  • the internal coolant supply prevents exposed hose lines for the coolant on the machine.
  • a honing tool with a cylindrical friction lining which has a longitudinal slot and is radially expandable
  • Standard honing tools which of course can also be used, have strips with friction linings, but these strips are in the machining of a workpiece to the outside bend and thereby can lead to an imbalance of the rotary driven tool. As a result, the tool vibrates, which can lead to destruction of both the workpiece and the tool.
  • honing tools with cylindrical friction lining these problems are avoided.
  • the honing machine can additionally be equipped with a measuring and / or deburring station. These processing steps of the workpiece can thus also be carried out within the honing machine.
  • the machine has a robot device for loading and unloading the workpiece carrier and / or the measuring station and / or the deburring station.
  • the robot device can be, for example, a six-axis robot device with which an arbitrarily shaped workpiece can be detected and moved through the processing space in any desired way and deposited at the desired location.
  • honing machines can be used for this purpose. They can be arranged directly next to each other.
  • the machine has a housing with closable openings, through which the processing space of the workpiece by robot means adjacent arranged honing machines or other processing machines or transport facilities is accessible.
  • a rough machining of the holes with a second machine finer machining and with a third machine, the finishing of the holes are made.
  • the workpieces can be from move the robotic devices of the machines from one machine to the next, or a new workpiece can be loaded while measuring and deburring just machined workpieces.
  • the honing machine 10 has a base 11, on which a stand 12 is arranged, which a tool spindle device 13 and a carriage 14, on which a workpiece carrier 15 is attached, are arranged.
  • the carriage 14 is driven to oscillate in the vertical direction by means of a linear motor, not shown here.
  • the carriage 14 may preferably be simultaneously the rotor of the linear motor.
  • the tool spindle 13, on the chuck 16 a honing tool can be fastened, is rotatably driven and can be adjusted on the stand 12 with respect to the workpiece carrier 15. It is also possible to drive the spindle 13 in the vertical direction oscillating.
  • a robot device 17, here a six-axis robot and a measuring device 18 are arranged on the base.
  • a workpiece (not shown here in detail) can be placed on the workpiece carrier 15, removed therefrom and fed to the measuring station 18. From the measuring station 18, the workpiece can be transferred, for example, to an adjacently arranged honing machine or another processing machine.
  • the honing machine 10 also has a control cabinet 19, in which in addition to the power supply and the control device of the machine is arranged. Next, a cooling unit 20 is provided, with the aid of the tool spindle 13, a coolant can be supplied.
  • the honing machine 10 also has a housing 21, the processing space 22 for the workpiece, the area between the stator 12 and the control cabinet 19 (FIGS. Fig. 1 ) and the region of the stator 12 and the cooling unit 20 to the outside closes.
  • the housing 21 has a viewing window 23 at the front and openings 24 which can be closed laterally by housing parts (not shown here). If several machines Hohnmaschinen 10 placed side by side, so the robot device 17 can transport through the openings 24 workpieces from the processing space 22 of a machine to the processing space 22 of the adjacent machine or vice versa.
  • the housing parts 25, 26 in the region of the gap between the cabinet 19 on the one hand and the stand 12 and the cooling unit 20 on the other hand are formed as doors. Through them, both the control cabinet 19 and the drives for the spindle 13 and the tool carriage 14 are accessible for repair work. Become several Honing machines arranged side by side, so the doors 25, 26 can be removed between the individual machines 10, creating a continuous inspection area for all machines.
