Definitions

  • the present invention relates to a vice for deburring foundry parts, comprising a clamping head to hold the parts while a worker is deburring them using an abrasive disc leveler.
  • the purpose of the present invention is to provide a new vice for clamping the foundry parts during their deburring, which reduces the loss of time for handling the parts, facilitates the work of workers and reduces the risk of accident.
  • the vice proposed by the present invention is essentially characterized in that the clamping head is mounted at the end of a rotary shaft driven by a motor under the action of at least one control pedal and comprises a fixed jaw and a movable jaw controlled hydraulically under the action of another control pedal.
  • the drive shaft is arranged horizontally and said movable jaw is movable vertically.
  • the movable jaw is preferably formed by the rods of two hydraulic cylinders incorporated in the clamping head.
  • the fixed jaw is preferably modifiable by means of a removable intermediate piece.
  • the clamping head is preferably replaceable thanks to a quick fixing on the shaft.
  • the shaft is housed in bearings of a height-adjustable support and on which are mounted a gear motor, an oleopneumatic unit and an electrical and pneumatic supply system, all under a cover. protection.
  • the shaft drive system is preferably designed to rotate it in both directions under the action of two control pedals.
  • the worker can therefore rotate, using his control pedal (s), the head of the vice during deburring and stop it in any position, in order to have an optimal presentation of the part to be trimmed and to have easy 360 ° access to this part.
  • the hydraulic clamping of the parts also makes clamping much faster and also more reliable, which increases the safety of the worker. Since the operator can operate the machine using control pedals, he can constantly hold the grinding wheel with two hands, which makes work easier and less exposed to the risk of injury.
  • Figure 1 shows a schematic overview of the vice proposed by the present invention
  • Figure 2 shows an enlarged side view of the clamping head
  • Figure 3 shows a plan view of the clamping head
  • Figure 4 shows a front view of the clamping head
  • Figure 5 shows a view of the rear of the clamping head.
  • Figure 1 shows a clamping head 10 which is movable about a horizontal axis of rotation O under the action of a drive shaft 12.
  • This drive shaft 12 is housed in a bearing 14 of a support 16, the feet of which are preferably adjustable in height by means known per se in order to adapt the level of the axis O to the size of the worker.
  • the end of the shaft 12 opposite to that carrying the clamping head 10 is driven by a geared motor 18 which makes it possible to actuate the shaft 12 and the clamping head 10 in both directions of the axis 0, this which is symbolized by the arrow A.
  • the reference 20 designates a box containing the electrical supply system
  • the reference 22 designates an oleopneumatic unit connected to the clamping head 10.
  • Three control pedals respectively serving to control the circuit hydraulic of the clamping head 10 and the rotation of the drive shaft 12 in one direction and the other, are grouped in 24, preferably on the floor below the clamping head 10 to allow the worker an easy control with the foot. These three pedals can be placed next to each other, but it is also possible to arrange the hydraulic control slightly apart from the electric controls to avoid a false operation, for example an unintentional control of the hydraulic release and a fall. accidental workpiece clamped in the head
  • Reference 26 designates a removable protective cover. It is possible to provide, above the vice, in a manner known per se, an extractor hood for discharging sparks and waste from deburring.
  • This head 10 which, as shown in Figure 2, generally has the shape of a section in "C" whose hollow part is directed towards the front in the direction of the axis O, and which is fixed from the rear to a flange 28 of the drive shaft 12. In the embodiment shown, this fixing is symbolized by screws 30. It it is however preferable to have several clamping heads 10 adapted to the different parts to be trimmed and, in this case, a quick attachment, known per se, for example, a dovetail attachment is required.
  • a block 32 provided with bores into which two hydraulic jacks 34, 36 are screwed is removably fixed in the front part of the head 10.
  • the rods 38, 40 of these jacks 34, 36 constitute the movable jaw of the vice , the fixed jaw being constituted by the upper part 42 of the head 10.
  • the reference 44 designates a part clamped between the jaws 38, 40 and 42 of the vice.
  • the disassembly of an intermediate piece 48 removably fixed on the fixed jaw 42 allows the clamping of the thicker pieces 46 as shown in FIG. 2.
  • the references 50, 52 designate convex heads screwed onto the rods 38, 40 cylinders 34, 36. In case of wear, it suffices to replace these heads 50, 52 without being obliged to replace the cylinders.
  • the hydraulic supply of the jacks 34 and 36 is carried out through a channel in the block 32 (see FIG. 4). This channel 54 can be connected by means of flexible pipes with quick connections to the hydraulic aggregate 22 of the support 16. It is however also possible to produce the electrical supply through the drive shaft 12, which allows to eliminate flexible hoses and eliminates the need to take measures so that these hoses do not wrap around the drive shaft 12.
  • a plate 56 screwed onto the hydraulic block 32 (see FIG. 2) (disassembled for clarity of the drawing in FIG. 4) protects the rods 38, 40 against projections from deburring.
