    A cutter-bit assembly employs an arcuate wedge to secure a cutter-bit within a pocket of a holder. The wedge fits into a tapered gap between complementary curved surfaces of the holder and the cutter-bit shank. A projecting insert carried by the shank mates with a serrated portion on the wedge. Contact is established between the wedge and the curved surfaces of the holder and the shank over outer regions separated by non-contacting clearances.

    The invention relates to the mining industry, namely to devices for fastening the incisors of mining machines,
    The aim of the invention is to increase the reliability of fixing the tool.
    Fig. 1 shows a device for fastening a cutter with a mountaineer of 1 Machines, a longitudinal section; Fig, 2 arcuate wedge, side view; in FIG. 3, in FIG. 2; Fig. 4, a device for fastening a cutter of a mining machine, an embodiment, a longitudinal section,
    The device for fastening the cutter of a mining machine includes a tool holder TEL 1 and a cutter 2, the cutting edge 3 of which is formed by a hard metal insert. The toolholder 1 in a known manner, for example by welding, is mounted on a rack of coal plow or another mining machine. To accommodate the cutter 2, the toolholder 1 has a slot 4, in which a plate holder 5 of the cutter 2 can be inserted into the side. The slot 4 on the reverse side is bounded by a rear wall 6o On the front side opposite to the cutting direction, the slot 4 has an end opening 7 which is located behind the partition 8, namely, between the partition 8 and the bottom 9 of the socket 4, as well as the hole 10 in the bottom 9, the rear wall of the socket 6, the partition 3 and the bottom 9 of the socket connect both parallel walls 11 of the socket 4, in which the transverse-oriented r is fixed Riding 4 tselngy cylindrical pin 12 connected to the wall 6 of the slot. The finger 12 forms a cylindrical support for the abutment of the cutter, "Cutter 2 consists of a plate holder 5, which at the opposite end has an approximately semi-circular tray-shaped support surface 13. On the support surface 13, the cutter 2 in an assembled position rests on a cylindrical support of a finger 12 Tray-shaped support surface 13 of the cutter forms on the back side of the cutter a protrusion 14, which covers the finger 12 Cutter 2 on the front end of the tool holder inserted into the slot 4 has a concave front face surface 15, -which is reacted with the arcuate surface of the wedge 16, outer surface 17 of the partition 8 of the convex rounded path to the socket 4; together with the concave front face 15 of the cutter 2, it forms an arcuate wedge gap, which narrows in the direction away from the tool holder 1 end into the face hole 7 of the tool holder 1 towards the end located on the other side of the partition 8. The arcuate wedge 16 has an arc length of approximately 180- 200%
    The device works as follows
    In order to fix the cutter 2, its holder 5 is inserted laterally with a deviation into the slot 4 of the toolholder 1 in such a way that its tray-shaped abutment surface 13 fits to the finger 12, B of the cutter 2 shown in FIG. 4, and 4 is arched through the end opening 7 toolholder 1, in re-. As a result, cutter 2 is firmly wedged in the socket. At the same time, the end sections 18 and 19 of the arcuate wedge 16 abut against both the convex outer surface 17 of the partition 8 of the toolholder 1 and the concave front end surface 15 of the tool 2, However, the middle portion 20 of the arcuate wedge 16 abuts against the partition 8 of the toolholder 1 and against the front end surface 15 cutter with a gap. In the exemplary embodiment according to FIG. 1-3, this is achieved due to the fact that the inner surface 21 is concave on the middle portion 20 of the arcuate wedge 16, due to the presence of a notch, somewhat separated from the convex outer surface 17 of the partition 8. In the embodiment according to FIG. 4, the fit of the middle section 20 of the arcuate wedge 16 to the partition with a gap is achieved by interacting with the middle section 20 of the arcuate wedge 16, the zone 22 of the convex outer surface 17 of the partition 8, due to the presence of a notch, is somewhat separated from the concave inner surface 21 of the arcuate wedge 16 o
    The outer surface 23 of the arcuate wedge 16 is convex in accordance with FIG. 1-3, due to the presence of a notch, it is also somewhat located on the middle section 20 from the concave front end surface 15 of the cutter 2, so that the arcuate wedge 16 both to the tool holder 1 and the tool 2 adjoins exclusively with its extreme sections 18 and 19. In the embodiment in 4, a portion 24 of the concave front face 15 of the cutter 2 which interacts with the middle section 20 of the arcuate wedge 16 is located at a distance from the convex outer surface 23 of the arcuate wedge 16 due to the presence of a notch.
    The concave end surface 15 of the cutter 2 has a cylindrical deaf hole 25 having a stepped recess 26. In the deaf hole 25 there is inserted a cylinder shaped cylinder {retainer 27 made of synthetic material, which is located at the opposite end of a cylindrical shank 28 of smaller diameter. It enters the stepped a recess 26 of a blind hole 25. In the retainer 27 of synthetic material, the safety pin 29 is inclined inserted in an oblique way.

    that it is reinforced on the back side in the groove 30 between the section 31 of large diameter and the stepped recess 26 of the blind hole is 25. The length of the fixer 2 from synthetic material and the safety pin 29 is chosen so that they protrude relative to the concave front end surface 15 of the cutter 2 by a certain amount, for example 1-2 mm. The arcuate wedge 16 has a gear rim 32, the tooth 33 of which interacts with the fixing
    5 rum 27 of synthetic material and with a safety pin 29. The tooth 33 is shaped in such a way that the arched wedge 16 is driven into the wedge gap against pyrdro up0 resistance to the retainer 27 of synthetic material, as well as the safety pin 29 embedded in it, without forming irreversible deformations at
    5, the knockout of the arcuate wedge 16 can only be carried out by cutting the retainer 27 from synthetic material and deforming the safety pin 29. The teeth 33 of the ring gear 32 are not filled over the entire width b, but only in the center of the zone L of the arcuate wedge 16, the gear teeth 32 It is located in the middle section 20, spaced some distance from the extreme sections 18 and 19 of the convex outer surface 23 of the arcuate wedge 16.
