Description

MASS REMOVAL DEVICE FOR BALANCING

The present invention relates to a mass removal device for balancing work, and in particular for rotational unbalance balancing work to improve the balancing work that was carried out by hand only to remove the rotational unbalance to increase the accuracy and speed of the work and to ensure the safety of the operator A mass removal device.

In general, the rotational unbalance is defined as a non-uniform distribution of the weight of the rotor with respect to the center of rotation of the rotor, that is, 'a state in the rotor when the vibration force or vibration movement due to the centrifugal force is transmitted to the bearing'.

  Due to the rotational unbalance, vibration and noise are caused when the rotating body (machine or part) is rotated, and greater force is generated when operating at high speed, causing instability of the whole system.

This rotational unbalance can be controlled by balancing the rotating body, and this is done by finding the amount and position of the unbalance and adding or removing the same amount of mass in the opposite direction of the rotor. As the mass is added or removed, the amount of noise and vibration reduction of the rotor and the stability of the system are determined.

The most common method of balancing through mass removal is drilling, which is currently the industry's most common means of manual balancing due to the lack of fixtures dedicated to drilling. Therefore, the accuracy and speed of the work is lowered, and there is a safety risk for the worker due to the configuration of the fixed device.

The vertical leg 110 is composed of a combination of the upper leg (110b) and the lower leg (110a), the lower end of the upper leg (110b) at the upper end of the lower leg (110a) pin coupling to enable tilting in the front and rear direction do. Here, the tilting operation of the upper leg 110b may be made by receiving a driving force by the driving motor M1 shown in the drawing, or the operator may directly tilt the upper leg 110b by applying a force to the upper leg 110b. When the upper leg 110b is configured to be tilted in the front and rear direction with respect to the lower leg 110a as described above, the drilling angle of the drill blade 161 mounted to the drilling machine 160 can be adjusted as shown in FIGS. 6 and 7. The drilling work for the workpiece (T) can be conveniently made at various angles. This tilting of the upper leg 110b is accomplished to the extent that it is horizontal with the drilling machine 160 as shown in FIG. 7.

The horizontal support beam 120 is horizontally installed in the horizontal direction by connecting the upper end of the pair of vertical legs (110). The horizontal support beam 120 is formed in the form of a rail having an inverted U-shaped cross section as shown in Figure 3 so that the left and right movable body 130 can move in the left and right directions. A plurality of through-holes 122 corresponding to the spring plunger 131 installed on the left and right moving body 130 are formed at regular intervals along the longitudinal direction on the front and / or rear of the horizontal support beam 120. In this way, the operator can directly position the left and right moving body 130 and the drilling machine 160 in a preset correct position without having a large servomotor. In addition, as shown in FIG. 3, a guide groove 121 in which the guide rollers 132 of the left and right moving bodies 130 are guided along the longitudinal direction is formed on the inner bottom surface of the horizontal support beam 120.

The left and right moving body 130 serves to allow the left and right movement of the drilling machine 160 while sliding along the horizontal support beam 120 to move in the left and right direction. The front and / or rear surface of the left and right movable body 130 is provided with a spring plunger 131 elastically supported by a spring so that the left and right movable body 130 is formed along the longitudinal direction of the horizontal support beam 120 You will be helped to ensure that you are in the correct position.

Here, a reduction gear assembly may be installed between the shaft and the pinion 150a of the motor, and the pinion 150a may be directly coupled to the shaft of the motor. Meanwhile, the rack 150b is engaged with the pinion 150a while vertically penetrating the guide hole of the supporter 140, and is installed to ascend and descend according to the rotation direction of the pinion 150a. Here, the drilling machine 160 is mounted on the lower end of the rack 150b so that the drilling machine 160 moves up and down as the rack 150b moves up and down. At this time, a scale 151 is printed on the side surface of the rack 150b so that the drilling depth of the drill blade 161 with respect to the workpiece T can be immediately recognized accurately.

The drilling machine 160 is mounted as a tool at the lower end of the rack 150b of the elevating member to perform a drilling operation on the workpiece (T). In the case of the drill blade 161 is installed long in the downward direction from the main body of the drilling machine 160 to basically remove the mass by drilling the workpiece (T) in the vertical direction, but the upper leg (110b) According to the tilting angle, the drilling angle for the workpiece T may be variously changed.

The elastic support rods 170 are respectively rotatably installed in the front and rear directions at both ends of the horizontal support beam 120 to maintain a vertical state. The elastic support bar 170 is connected to the multi-stage so that a plurality of nodes overlap in the longitudinal direction can be inserted into a stretchable configuration. In the case of the elastic support rod 170 having such a configuration, the lower end portion is in contact with the ground while maintaining the vertical state during the tilting operation of the upper leg 110b so that the horizontal support beam 120 can be supported so as not to be rolled over. Here, a motor (not shown) for providing a driving force for the telescopic support rod 170 to expand and contract and a motor (not shown) for providing a driving force for rotating the telescopic support rod 170 in front and rear directions are installed at both ends of the support beam. An angle measuring sensor (not shown) is installed to detect the rotational angle of the upper leg 110b or the elastic support bar 170 so that the elastic support bar 170 can be maintained vertically. In addition, a controller is installed so as to control motors that provide driving force to the stretchable support bar 170 in conjunction with the angle measuring sensor.

The front and rear rails 180 serve to slidably support the lower end of the vertical leg 110 in the front and rear directions. The front and rear rails 180 are formed to have a U-shaped cross section as shown in FIG. 1, and a plurality of wheels 111 which are rollable for sliding operation are installed at a lower end of the vertical leg 110.

In addition, the front and rear conveyor 190 for moving the workpiece (T) along the front and rear direction is preferably installed as shown in FIG.
