Description
Technical Field
The utility model belongs to the technical field of machining instrument, concretely relates to quick toolchanger for auto-feed bores.
Background
The length of the automatic feeding drill is about 300-600mm, a hole making cutter with the length of 2-30mm can be clamped, hole making processing with fixed rotating speed and fixed feeding speed on the surface of any workpiece can be realized by matching with a drill plate, and the automatic feeding drill becomes the most common hole making tool in the field of aviation equipment due to compact structure and comprehensive functions, and hundreds of automatic feeding drills with different sizes are required for assembling one airplane.
However, since the tool itself is compact, the hole-machining tool to which the tool is adapted is usually a threaded shank, and the tool for mounting and dismounting the threaded shank needs to use a wrench to fix both ends of the thread, i.e., the rotation shaft of the auto-feed drill end and the end of the hole-making tool, and to lock or separate them by means of torque. Generally, in field operation, the automatic feed drill is horizontally placed on a table top or the ground, an operator fixes the threaded handle end of the rotary main shaft of the automatic feed drill by using one wrench and twists the drilling tool end by using the other wrench, so that the cutter is separated from the automatic feed drill device.
The method is time-consuming and labor-consuming, and when the large-caliber drill bit is installed, due to the fact that a large locking torque is needed, two operators often need to exert force at the same time, the locking torque is difficult to determine, the situation that the drill bit is not installed in place or cannot be detached easily occurs, equipment damage can be caused, and accidental injury can be easily brought to the operators.
Patent CN208744673U combines two spanners together, has solved the uneven problem that still goes to looking for everywhere of spanner specification, still can not solve the operation degree of difficulty height, can't confirm locking torque scheduling problem yet.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: the utility model aims at providing a quick toolchanger for auto-feed bores has solved current auto-feed and has bored the problem of dismantling the difficulty with the cutter.
The technical scheme is as follows: the utility model relates to a quick toolchanger for automatic feed bores, comprising a base plate, the bottom plate passes through locking bolt fixed mounting on the workstation, bolt difference fixedly connected with lock blade holder and supporting seat are passed through at the both ends of bottom plate, the top intermediate position of lock blade holder is equipped with the breach, the breach interpolation is equipped with the lock edge of a knife, the top of lock edge of a knife is equipped with the dop that two sets of symmetries set up, bolt fixedly connected with supporting seat support port is passed through on the top of supporting seat, install the automatic feed that the level set up between supporting seat support port and the lock edge of a knife and bore, just the rotation axis bayonet socket of automatic feed bore and the dop phase-match of lock edge of a knife.
Furthermore, the central height of the supporting opening of the supporting seat is the same as that of the lock knife edge. Therefore, the automatic feed drill can be ensured to be in a horizontal state, so that the automatic feed drill is prevented from generating overturning moment in the tool changing process, and equipment is prevented from being damaged.
Furthermore, the shape of the notch is a hexagonal structure, and the shape of a lock knife edge inserted in the notch is also a hexagonal structure. This way, the torsional moment can be stably transmitted.
Further, a cutter is connected to the end of the rotating shaft of the automatic feed drill in a threaded manner. The cutter can be a hole machining cutter such as a drilling cutter, a reamer, a countersink cutter and the like.
Furthermore, a plurality of groups of threaded holes are formed in the bottom plate at equal intervals. The screw hole is used for fixed lock blade holder and supporting seat to can be according to the size of auto-feed brill, the position of allotment lock blade holder and supporting seat, with the quick tool changing demand that satisfies not unidimensional auto-feed brill.
Furthermore, the distance between the lock tool apron and the lock bolt is close. Because the tool locking seat is a part bearing the loading and unloading load of the tool, the tool locking seat is close to the locking bolt as much as possible, so that larger moment can be conveniently obtained, and the deformation of the bottom plate is reduced.
Compared with the prior art, this patent has following advantage and beneficial effect:
(1) the tool changing operation of the automatic feeding drill is convenient for operators to carry out, and the consistency of the tool changing process is improved;
(2) the central height of the supporting port of the supporting seat is consistent with that of the lock cutter edge so as to realize the horizontal placement of the automatic feeding drill;
(3) a plurality of groups of threaded holes are formed in the bottom plate at equal intervals, so that the position adjustment of the tool locking seat and the supporting seat is facilitated, and the requirement for quick tool changing of automatic feed drills of different sizes is met;
(4) the notch and the cutter locking opening adopt a hexagonal mode, a rotating shaft bayonet of the automatic feeding drill is matched with a clamping head of the cutter locking opening, and the two modes can realize the transmission of torque.
