Definitions

  • the present invention relates to an automatic machine for deburring small parts.
  • the present invention aims to remedy these drawbacks by providing a machine with a particularly simple design, making it possible to deburr small parts on both sides without using a powdery abrasive agent.
  • this automatic machine for deburring small parts comprising at least one conveyor belt on which are brought the parts to be deburred, at least one deburring brush driven in rotation about a horizontal and transverse axis, at -Dessus the conveyor belt and substantially tangent thereto, and, upstream of each brush trimming, a pressure pad arranged at a short distance above 'the carpet is characterized in that the underside of the pressure pad is coated a layer of a material allowing the parts to be machined to pass downstream without appreciable friction and opposing any movement of these parts upstream.
  • the automatic deburring machine according to the invention which is shown in FIG. 1 comprises two endless conveyor belts, namely an upper conveyor belt 1 and a lower conveyor belt 2 which extend horizontally between drive drums 3, 4 and return drums 5, 6.
  • the two conveyor belts 1, 2 are moved in opposite directions to each other, the upper strand 1a of the conveyor belt 1 being moved from right to left in FIG. 1, return drum 5 to the drive drum 3 located on the left, while the upper strand 2a of the lower conveyor belt 2 is moved from left to right, from the return drum 6 to the drive drum 4 located on the right.
  • the parts to be deburred 7, of small dimensions are brought to the upper conveyor belt 1, at the upstream end thereof, that is to say above the right return drum 5. These parts are thus moved from right to left by the upper strand 1a of the conveyor belt 1 and they pass successively through two upper deburring stations 8, 9 respectively comprising deburring brushes. 11, 12. These two brushes 11 , 12 are each mounted to rotate about a horizontal and transverse axis, they are located above the upper strand 1a of the conveyor belt 1 and they are substantially tangent to the latter.
  • deburring brushes made of a relatively hard abrasive material rotate in opposite directions to each other, the brush 11 of the first station deburring 8 turning for example clockwise while the brush 12 of the second upper deburring station 9 rotates counterclockwise.
  • These two brushes 11, 12 are rotated by respective individual electric motors 13, 14. They are also driven in an alternating movement in the transverse direction, along the arrow f, as indicated in FIG. 2, by a device 15 known per se and which will not be described in detail.
  • the deburring machine comprises, upstream of the brush 11, 12 of each of the deburring stations 8, 9, a pressing pad 16 which is placed a short distance above the upper run of the conveyor belt 1 , as can best be seen in FIG. 3.
  • This pressing pad 16 has, in vertical section, the shape of a wedge whose upper face 17 which is adjacent to the brush 12 has a curvature with a concavity turned upwards and towards the brush 12.
  • the lower face 18 of the shoe 16 which is located a short distance from the strand 1a of the conveyor, is preferably slightly inclined in the direction of this strand in the direction of advancement of the parts 7.
  • a layer 19 of a "non-return" material that is to say which lets the parts 7 pass without resistance in the direction of advancement of the strand 1a of the conveyor belt and which on the other hand effectively brakes any movement in reverse.
  • the presser shoe 16 extends over all or only part of the width of the strand 1a of the conveyor belt.
  • This shoe is articulated about a transverse axis 21, on a support 22 mounted vertically adjustable on the frame of the device.
  • This support 22 carries a horizontal upper tab 23, extending rearward, through which is screwed a vertical pressure adjustment screw 24.
  • This screw 24 also passes through a horizontal tab 25 extending rearward the shoe 16, at his upper part, above the hinge axis 21.
  • the screw 24 is terminated, at its lower end, by a flat head 26.
  • a compression spring 27 is disposed between the head 26 of the screw 24 and the face lower leg 25.
  • a thickness limiting stop 28 is interposed vertically between the two legs 23 and 25.
  • the spring 27 is more or less compressed between the head 26 and the wing 25, which makes it possible to vary the pressure exerted by the lower face 18 on the parts 7 when the latter pass under the pressing pad 16 and slightly lift the latter. Furthermore, the stop 28 maintains the presser shoe 16 at rest in a position corresponding to a determined passage height between its lower face 18 and the strand 1a of the conveyor belt.
  • each of the parts 7 is held firmly on the strand 1a of the conveyor belt 1 while being advanced under the deburring brushes 11, 12, even when these parts pass under the brush 12 rotating with a tangential speed opposite to the direction of movement of the parts.
  • the machine comprises, as we have seen previously, a second lower conveyor belt 2 with which are associated two additional deburring stations 31, 32 arranged above the upper strand 2a of the conveyor belt 2 and comprising brushes 33, 34 rotating in opposite directions to one another.
  • Each of these deburring stations 31, 32 also includes a pressing pad 16 mounted in the same way as the pads 16 associated with the upper deburring stations 8, 9.
  • the deburring machine according to the invention also comprises a device making it possible to ensure the reversal, the descent and the braking of the parts 7.
  • This device comprises a flexible brush 35 of horizontal and transverse axis and which is tangent to the drive drum left 3 of the upper conveyor belt 1.
  • This flexible brush 35 is rotated in the opposite direction of the drum 3, substantially at the same tangential speed as that of the drum 3, that is to say at the speed of translation of the conveyor belt 1.
  • the brush 35 is driven in rotation by a chain 36, from a general drive device 37 also ensuring the driving of the drums 3, 4.
  • a sliding ramp 38 which is preferably curved and whose lower end part 38a is located just above the upper strand 2a of the conveyor belt 2, in the left part che thereof, that is to say on the upstream side of this strand.
  • a flexible braking brush 39 of horizontal and transverse axis, which is tangent to this end portion 38a. This flexible brush 39 is rotated from the general drive device 37, so as to have a tangential speed substantially equal to the speed of advancement of the parts 7 on the upper strand 2a of the conveyor belt 2.
