Description
Technical Field
The utility model belongs to the technical field of drilling, especially, relate to a drilling machine that can automatic switching cutter.
Background
At present, in the machining industry, for machining parts which are provided with holes at two ends, large in batch and high in precision, a centering hole is usually drilled first, and then the hole is drilled, namely, a drilling procedure is completed by two times. Therefore, the clamping is carried out twice, so that the accumulation of machining errors is caused, the product precision is low, and the production efficiency is low. Therefore, the applicant proposes "a drilling machine tool for converting a tool", with the following authorization notice numbers: CN201267883Y, this lathe is through the rotation of distribution axle, and the rotational speed changes through changing the gear, and the distribution axle is rotatory to be driven, transposition cam feed cam rotates, and transposition cam drives the rig floor translation, and feed cam stirs the lever, and the lever stirs the cutter and feeds to accomplish the cutter transposition and drill and feed, accomplish through a clamping and bore two processes of boring the centre bore and boring hole, can improve work efficiency. However, the machine tool still has the following disadvantages: the change of the rotating speed of the distribution shaft can be realized only by stopping the machine to replace different gears, so that the gear needs to be replaced repeatedly under the condition of processing requirements, and serious inconvenience is brought to production.
Disclosure of Invention
In order to solve the problem that exists among the prior art, the utility model aims at providing a drilling machine tool that can automatic change over cutter, this lathe passes through gear motor drive distribution axle for automatic adjustment can be realized to the rotational speed of distribution axle, need not shut down the speed governing, improvement production efficiency that can be by a wide margin.
In order to realize the purpose of the utility model, the utility model adopts the following technical scheme:
the utility model provides a drilling lathe that can automatic change-over cutter, includes transposition cam, distribution axle, cam and lever, and the cam setting is provided with cam, its characterized in that at a tip of distribution axle, at the middle part of distribution axle: the other end of the distribution shaft is connected with a speed reducing motor through a coupler, the middle part of the lever is pivoted on the support through a vertical rotating shaft, and a torsion spring is arranged between the lever and the vertical rotating shaft.
Furthermore, the cam is cylindrical, and a V-shaped notch is formed in one end of the outer circular surface of the cam.
Furthermore, a vertical deflector rod is arranged at one end of the lever and is correspondingly contacted with one end face of the cam.
Due to the adoption of the technical scheme, the utility model discloses following superiority has:
the distribution shaft is driven by the speed reducing motor, so that the rotating speed of the distribution shaft can be conveniently adjusted, the operation that the gear needs to be stopped and replaced when the rotating speed is changed in the prior art is avoided, and the working efficiency is greatly improved; the torsion spring is arranged between the vertical rotating shaft and the lever, so that the lever can reset automatically, and the cutter feeding is automatically realized.
