Abstract
The utility model discloses a rotary arm type tap, which comprises a frame, a column fixed on the frame, a rotary lifting arm which can move up and down along the column, and a rotary arm connected to the rotary lifting arm. One end of the rotary arm is provided with a tapping head driven by a motor through a reducing mechanism, and the drive motor of the tapping head is a hydraulic motor. The hydraulic motor is connected with a duplex gear wheel pump having two different output speeds and higher output speed of the duplex gear wheel pump is two times larger than the lower output speed. In order to make the tapping head part easily and randomly move, the rotary arm is also provided with a counterweight and load shedding mechanism. The utility model changes the air pressure power source of the prior art into a hydraulic power source, and correspondingly changes an air pressure motor into a hydraulic motor, and the tapping tooth force is improved more than ten times.
Description
Technical field
The utility model relates to a kind of tapping machine that is used for the tapping machine, particularly a kind of pivoted arm of thread mill drilling.
Background technology
Existing pivoted arm tapping machine, the rotation and lifting arm that generally includes frame, is fixed on column on the frame, can move up and down and can rotate around column along column and be connected pivoted arm on the rotation and lifting arm, one end of pivoted arm is provided with the tapping head that is driven by motor, and its effect by pivoted arm and rotation and lifting arm makes the tapping head can move to the optional position, space.Because the interaction of pivoted arm and rotation and lifting arm guarantees that the perpendicularity of screw, its power are to drive air motor by source of the gas thereby a tapping vertical is descended, drive a cover planetary gear reducing mechanism by air motor again and pass to the tapping head then; The rotating speed of air pressure motor is controlled by entering its inner tolerance, and the rotating speed of threading tool is controlled by the operating grip that is contained on the air pressure motor with turning to then.The gravity of head section, rocking arm and rotation and lifting arm relies on the air spring that is contained in parallel-crank mechanism inside to come balance.This pneumatic pivoted arm tapping machine since with gas as power source, and the pressure of gas is very limited, makes maximum tapping diameter have only M10, has greatly limited the application of this tapping machine.
Summary of the invention
The purpose of this utility model is to overcome prior art and uses the deficiency of air pressure as power source, provides a kind of pivoted arm tapping machine that utilizes hydraulic pressure as power source, to improve its tapping scope; Also have a purpose to provide a kind of pivoted arm tapping machine that surges in addition, it is provided with counterweight Reduction of Students' Study Load mechanism, with the weight of balancing machine head part, rocking arm and rotation and lifting arm portion better, the tapping head part can be moved easily.
The purpose of this utility model is achieved by following technical proposals: a kind of pivoted arm tapping machine, the rotation and lifting arm that comprises frame, is fixed on column on the frame, can move up and down and can rotate around column along column and be connected pivoted arm on the rotation and lifting arm, one end of pivoted arm is provided with the tapping head that is driven by reducing gear by motor, and the CD-ROM drive motor of this tapping head is a hydraulic motor.
Described hydraulic motor links to each other with the duplex gear pump with two kinds of different output speeds, and the higher output speed of this duplex gear pump is the twice of low output speed; Between described duplex gear pump and hydraulic motor, have overflow valve and reversal valve.
For the weight of balancing machine head part, rocking arm and rotation and lifting arm portion better, the tapping head part can be moved easily, can also be provided with counterweight Reduction of Students' Study Load mechanism on this pivoted arm.
The utility model changes the Pneumatic pressure power source of prior art into hydraulic power supply, correspondingly air pressure motor is changed into hydraulic motor, and the pressure of hydraulic pressure is more than ten times of air pressure, through the scene use show that the maximum tapping diameter of the tapping machine that surges is as M20 more than, do not do in the structure of existing equipment under the situation of too big change that its tapping scope is more than doubled.In addition in the prior art, the gravity of head section, rocking arm and rotation and lifting arm only relies on the air spring that is contained in rotation and lifting arm inside to come balance, cost height so not only, effect is also undesirable, be provided with the gravity that counterweight Reduction of Students' Study Load mechanism comes balancing machine head part, rocking arm and rotation and lifting arm portion in the utility model, the tapping head part can be moved more easily.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
As shown in Figure 1, the rotation and lifting arm 3 that the utility model pivoted arm tapping machine comprises frame 1, be fixed on column 2 on the frame, can move up and down and can rotate around column along column and be connected pivoted arm 5 on the rotation and lifting arm 3 by rotating shaft 4, one end of pivoted arm 5 is provided with the tapping that driven by coaxial-type double reduction machine 7 by hydraulic motor 68, is respectively equipped with the handgrip (not shown) on rotation and lifting arm 3 and pivoted arm 5.Under the acting in conjunction of rotation and lifting arm 3 and pivoted arm 5, tapping 8 can move to arbitrary position of frame top processing space, does elevating movement along vertical line during work, workpiece 9 is carried out the processing of auger shell pit, thereby guaranteed the perpendicularity of screw.
