Abstract
The utility model discloses a secure high-speed bench drill, and relates to a drilling machine equipment technology. The secure high-speed bench drill comprises a machine seat, a main shaft box, a variable frequency motor, two groups of tower-type synchronous belt pulleys, a synchronous belt, an overload clutch and a main shaft, wherein the machine seat is a mounting and supporting mechanism for all the parts; the main shaft box is fixedly arranged above the machine seat; the main shaft is arranged above the main shaft box; one group of tower-type synchronous belt pulleys are arranged on the top of the main shaft through the overload clutch; the variable frequency motor is also fixedly arranged on the main shaft box; the axis of the variable frequency motor is parallel to the axis of the main shaft; the other group of tower-type synchronous belt pulleys are oppositely fixedly arranged on a motor shaft relative to the first group of tower-type synchronous belt pulleys on the main shaft; and the variable frequency motor is connected with the tower-type synchronous belt pulleys on the main shaft through the synchronous belt.
Description
Technical field
The utility model relates to a kind of drilling machine equipment technical field bench drill, specifically is meant a kind of safety high speed bench drill with security function and higher rotation speed.
Background technology
Bench drill is a kind of machine tool simple in structure.The high-speed bench drilling machine tradition adopts Triangular Belt's at present, and frictional force is little skids easily, and noise is big behind the rotating speed height, about 8000 rev/mins, is not easy to reach at a high speed.Along with the fast development of industry such as electronics, instrument, instrument, clock and watch, the drilling machine that bores aperture there is new demand, expectation has that rotating speed is high, volume is little, in light weight, the high-speed bench drilling machine of reasonable price.Present domestic high-speed bench drilling machine has adapted to not the modern industry development need; Though occur the higher high-speed bench drilling machine of rotating speed in the prior art; But because employing is to agree with belt drive mechanism more, the further raising of rotating speed still receives certain restriction, and owing to there is not safety guard; Under higher working speed, the quality and safety accident appears easily.
The utility model content
The utility model realizes that the technical scheme that above-mentioned purpose adopted is: the utility model is on the basis of existing bench drill; Safety clutch is set on final drive shaft; Transmission mechanism adopts tower synchronous pulley, adopts band transmission synchronously between the tower synchronous pulley, and power adopts variable-frequency motor.This safety high speed bench drill comprises support, main spindle box, variable-frequency motor, tower synchronous pulley, synchronous band, safety clutch, main shaft; It is characterized in that: described support is the installation and the supporting device of whole parts; Main spindle box is fixedly mounted on above the support; Described main shaft is installed on the main spindle box; Described tower synchronous pulley constitutes by identical two groups, and wherein one group is installed in the top of main shaft through safety clutch, on main spindle box, also fixedly mounts variable-frequency motor simultaneously; The axis of variable-frequency motor and the axis of main shaft are parallel to each other, other one group tower synchronous pulley be installed in one group of synchronous pulley on the main shaft be fixedly mounted in the opposite directionly motor shaft above.Described tower synchronous pulley is made up of cone pulley body and synchronous pulley; Have synchronous teeth groove on the cylindrical of said synchronous pulley in uniform way; The parallel axes of described synchronous teeth groove direction and synchronizing wheel self; The synchronous pulley of different-diameter is fixedly mounted on above the cone pulley body through junction of the edges of two sheets of paper screw, and band couples together variable-frequency motor and the tower synchronous pulley above the main shaft synchronously.
Beneficial effect: the utility model is because power adopts variable-frequency motor; The tower synchronous pulley transmission system of transmission adopted; And at the top of main shaft installation safety clutch; So the utility model can move safely, has the advantage safe, efficient, that the duty adjustable range is wider under high rotational speed.
Description of drawings
Fig. 1 is the structure principle chart of the utility model.
Shown in the figure: 1. support, 2. main spindle box, 3. variable-frequency motor, 4. tower synchronous pulley, 5. band, 6. safety clutch, 7. main shaft synchronously.
The specific embodiment
In the drawings; This safety high speed bench drill comprises support 1, main spindle box 2, variable-frequency motor 3, tower synchronous pulley 4, is with 5 synchronously, safety clutch 6, main shaft 7; Described main spindle box 2 is fixedly mounted on above the support 1, and main shaft 7 is installed on the main spindle box 2, and tower synchronous pulley 4 constitutes by identical two groups; One group of top that is installed in main shaft 7 through safety clutch 6 wherein; On main spindle box 2, also fixedly mount variable-frequency motor 3 simultaneously, the axis of the axis of variable-frequency motor 3 and main shaft 7 is parallel to each other, other one group tower synchronous pulley 4 be installed in one group of tower synchronous pulley 4 on the main shaft 7 be fixedly mounted in the opposite directionly variable-frequency motor 3 motor shafts above; On the cylindrical of tower synchronous pulley, have synchronous teeth groove in uniform way, with 5 variable-frequency motor 3 and the tower synchronous pulley 4 above the main shaft 7 are coupled together synchronously.
