Definitions

  • the invention relates to a workpiece machining lathe, in particular a vertical lathe, comprising a machine frame or stand which has a machine front and a machine back, further first and second workpiece holding spindles, first and second tool carriers, displacement devices arranged on the machine front for the workpiece holding spindles and the tool holders , a workpiece processing room and workpiece feed and removal means.
  • the invention also relates to methods for parallel machining of workpieces.
  • Such vertical lathes with two spindles are known per se (DE-A-43 16 166 and DE-A 101 03 918).
  • a spindle and a tool carrier are mounted on cross slides, which can be moved along the machine bed, so that a workpiece picked up and clamped by the movable spindle can be transferred and transferred from a first processing point to a second processing point for further processing.
  • the workpieces are fed in on one side of the machine to the front of the machine stand and removed on the other side of the machine, also on the front of the machine stand.
  • Such vertical lathes are bulky and expensive. Furthermore, large masses for the Transfer of the workpieces are moved, which adversely affects the cycle times of the machine.
  • the invention has for its object to design a workpiece machining lathe of the type specified in a smaller and faster working.
  • the machine stand which can also be referred to as a machine frame or machine bed, has a channel running from the rear of the machine to the front of the machine, along which a loading carriage can be moved, which has two workpiece receiving points arranged next to one another, which, during operation of the loading carriage, convey conveyors for the raw workpieces in form the workpiece machining area into it and for the return transport of the machined workpiece.
  • the loading carriage is thus used twice, as a workpiece feed and as a workpiece removal means.
  • This double benefit corresponds to providing two workpiece receiving points in succession in each path, namely a first workpiece receiving point for raw workpieces and a second workpiece receiving point for machined workpieces. In this way, two raw workpieces can be conveyed into the workpiece machining area on the way there and two machined workpieces can be transported back on the way back.
  • the loading carriage thus has four workpiece receiving points, which are arranged in pairs next to and behind one another and can be moved in different positions, as is the case corresponds to the machine cycle.
  • a loading and unloading position is provided on the back of the machine, in which raw workpieces can be loaded and machined workpieces can be unloaded or reloaded at the same time.
  • two empty pick-up points of the loading carriage are first moved to transfer a machined workpiece in order to clear the respective workpiece-holding spindle arranged above the loading carriage, after which the loading carriage with its raw workpiece is moved below the assigned released workpiece-holding spindle, so that the latter can now pick up and clamp the workpiece to be machined.
  • machined workpiece is transported to the rear of the machine and, while unloading, reloading or reloading is carried out on the rear of the machine, the workpieces clamped in each case are machined on the front of the machine.
  • the machine is suitable for parallel processing of two workpieces, which can be of the same or different types. It is possible to consider the machine as two-hip, with one hip or machine half processing one workpiece and the other hip or machine half processing the other workpiece at the same time. If the parts are the same, machining is carried out in both hips using the same program, and if the parts are different, the machining is carried out using different machining programs.
  • FIG. 1 shows a vertical lathe, seen from the front
  • FIG. 2 shows a cross section through the vertical lathe
  • FIG. 3 shows the position of the vertical lathe in the loading / unloading position
  • FIG. 4 in the transfer phase of a machined workpiece
  • FIG. 5 6 in the pick-up phase of a raw workpiece
  • FIG. 6 in the phase of returning a machined workpiece
  • FIG. 7 an enlarged detail from FIG. 1 when machining different workpieces
  • FIG. 8 when machining a type of workpiece in succession
  • FIG. 9 shows a plan view of a loading area of a loading carriage
  • FIG. 10 shows a side view of a loading carriage.
  • Fig. 1 shows the front of a two-spindle machine
  • the main components of the machine are: the machine frame 1, a workpiece processing space 2 attached to it, a first workpiece holding spindle 3, a second workpiece holding spindle 4, a first tool carrier 5, a second tool carrier 6 and displacement devices in the form of slide drives 7 for the spindles and slide drives 8 for the tool carriers.
  • a loading carriage 9 is shown schematically in FIG. 2, which can be moved by a carriage channel 10 from the rear of the machine 11 to the front of the machine 12 and back.
  • the carriage 9 is shown in FIGS. 2 and 3 in the loading position in which it has loaded a raw workpiece 13.
  • the spindle 3, 4 is reproduced with a machined workpiece 14.
  • the machine frame 1 forms a stand, which also forms a bed for the various displacement devices.
  • the spindles 3, 4 each have rotary drives 15 and can be moved up and down with carriages 17, which can be moved by the drives 7, as indicated by arrows.
  • the tool carriers 5, 6 can be adjusted in the correct position relative to the workpieces, a linear slide 18 being used for the horizontal axis (x-axis) or a cross slide for the x- and y-axes, the latter for milling and Drilling work in the Y direction.
  • the tool carrier 5, 6 is designed as a turret, i. H. the individual tools 19 can also be brought into position by turning.
  • the work area 2 can be secured by sliding walls which are intended to prevent chips flying around from escaping.
  • the sliding walls can be moved up from the side or lowered from above, which is not shown in detail.
  • the loading carriage 9 is designed as a telescopic carriage, ie with a lower carriage 20 and an upper carriage 21. Lower and upper carriages are coupled to one another in such a way that when the lower carriage travels one path length, the upper carriage is shifted by two path lengths.
  • the upper slide 21 has four workpiece receiving points 22 to 25, of which the points 22 and 24 and 23 and 25 lie next to one another and the points 22 and 23 as well as 24 and 25 lie behind one another. Pairs lying one behind the other move along mutually parallel tracks 26 and 27 as a result of the displacement of the upper slide 21.
  • the workpiece receiving points 22 and 24 are provided with spring supports 28 in order to cushion workpieces lying on them when they are gripped by the holding spindles 3, 4.
  • Workpiece feed means and workpiece removal means are assigned to the machine tool in order to procure raw parts and remove finished parts.
  • This workpiece feed and removal means work automatically with the loading carriage, which is known in its nature and is therefore not shown in detail.
  • a transhipment turning station which is arranged on the rear of the machine and makes it possible to transfer workpieces that are unloaded, for example, from the pick-up point 23 to the pick-up point 24 while simultaneously turning through 180 °.
  • the machine operates as follows:
  • the workpiece receiving points 22 and 24 are loaded with workpieces of different types.
  • the functional sequence follows, as described with FIGS. 3 to 6. However, workpieces A are machined in one half of the machine and workpieces B in the other half of the machine, each with suitable machining programs (FIG. 7).
  • the functional sequence is basically as described under B. However, the partially machined workpieces of the web 26 are reloaded onto the second web 27, in most cases with simultaneous turning of the workpiece.
  • the workpiece machining area 2 can be referred to as a double work station, since two parts can be machined in it at the same time.
  • This summary of the workplaces saves a lot of machine floor space, since the mobile spindle no longer needs to be moved from one workstation to another. It also saves on cycle time because the reloading of partially machined workpieces is no longer carried out with the help of the mobile spindle, which is therefore free to only perform its function as a machining drive.
