Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a tapping drill bit convenient to dismantle and change for floor type boring machine as shown in fig. 1-3, including

mount pad

1, 1 swing joint of mount pad has tapping

drill bit

2, 1 radial rotation of mount pad installs a plurality of internal thread covers 3, the 3 inboard threaded connection of internal thread cover is provided with

screw rod

4, 4 tip fixedly connected with of screw rod support block 5, the one end fixed mounting that internal thread cover 3 stretched out mount pad 1 has gear 6, ring 7 has been cup jointed on the mount pad 1, ring 7 is connected with gear 6 meshing transmission through the driving tooth 8 that the lower side ring was established, ring 7 has stop screw 10 through screw hole 9 threaded connection. When the tapping drill bit 2 needs to be disassembled, the limiting screw 10 is unscrewed firstly, then the ring 7 rotates clockwise, the ring 7 drives the plurality of internal thread sleeves 3 on the gear 6 to rotate through the transmission teeth 8, so that the screw 4 on the inner side of the internal thread sleeve 3 is driven to move towards the direction away from the tapping drill bit 2, the pressing block 5 is separated from the tapping drill bit 2, then the fixing screw 15 is unscrewed to enable the pressing block 16 to be separated from the fixing groove 17, and then the tapping drill bit 2 can be disassembled from the mounting seat 1 quickly. The screw rod 4 does not need to be unscrewed for multiple times, time and labor are saved, and the working efficiency is improved. In a similar way, when the tapping drill bit 2 needs to be installed, the ring 7 rotates anticlockwise, so that the screw drives the pressing block 5 to move towards the direction close to the tapping drill bit 2, and the tapping drill bit 2 is pressed and fixed.

The tip of screw rod 4 has seted up

spout

11, 1 inner wall of mount pad is provided with gag lever post 12, the one end of gag lever post 12 inserts spout 11. When the internal thread sleeve 3 rotates, the screw rod 4 is driven to move, the limiting rod 12 slides through the sliding groove 11 at the bottom of the screw rod 4, so that the screw rod 4 moves back and forth, and circumferential rotation is avoided.

The terminal pressure head 13 that is provided with of stop screw 10, a plurality of arch has been laid on pressure head 13 surface, 1 surface of mount pad is the frosting. After the tapping drill bit 2 is fixed on the screw rod 4, the limiting screw rod 10 is screwed down, so that the pressure head 13 at the tail end of the limiting screw rod 10 penetrates through the circular ring 7 to contact the mounting seat 1, the circular ring 7 is limited, and the situation that the circular ring 7 rotates to drive the gear 6 to rotate during working is prevented, and the screw rod 4 rotates. When the protrusions on the surface of the pressure head 13 contact with the frosting surface, the friction force between the protrusions and the frosting surface is increased, so that the circular ring 7 is fixed more stably.

The side surface of the pressing block 16 is an arc surface. The shank of the tapping drill bit 2 can be clamped better. The mounting seat 1 is in threaded connection with a fixing screw 15 through a fixing hole 14, and the fixing screw 15 is provided with a pressing block 16. After screw rod 4 presss from both sides tightly tapping drill 2, the rethread is twisted and is fastened the briquetting 16 that set screw 15 made 15 tip of set screw and in getting into the fixed slot 17 on the 2 outer walls of tapping drill, further fixes tapping drill 2 for tapping drill 2 is fixed more stably. The risk of falling off during operation is reduced.

The outer wall of the tapping drill bit 2 is provided with a fixing groove 17 corresponding to the pressing block 16, the top of the tapping drill bit 2 is provided with an embedded groove 18, two ends of the top of the tapping drill bit 2 and two ends of the top of the inner side of the mounting seat 1 are provided with corresponding magnets 19, and the inner side of the mounting seat 1 is provided with an embedded block 20 corresponding to the embedded groove 18. When tapping drill 2 is required to be installed, tapping drill 2 is vertically placed into mounting base 1, embedded block 20 on mounting base 1 can be quickly connected with embedded groove 18 on tapping drill 2 through magnet 19, so that installation of tapping drill 2 is more quick and convenient, and subsequent operation can be quickly performed.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
