Description

Jig device for hand grinder mounting

The present invention relates to a jig device for mounting a hand grinder, and more particularly, to a jig device for mounting a hand grinder capable of grinding and grinding a flat material to a uniform thickness.

In general, in order to firmly and stably grip the hand grinder, the operator needs more force and has no choice but to perform the work in an uncomfortable position, and the operator has to repeatedly move the grinder left and right to handle it, which puts a strain on the operator's wrist. .

In addition, since it is necessary to work with a heavy grinder for a long time, the operator's arms, shoulders, and waist are strained.

As a result, the finishing operation by the method according to the prior art has very low work efficiency, and the worker who performs the mapping operation by the method according to the prior art is easily exposed to musculoskeletal disorders.

In addition, if the work that puts a strain on the body is performed for a long time, the precise grinding work may be difficult, and the object may be damaged by the insufficient grinding work or the excessive grinding work.

It is configured to include a rear plate 350 vertically coupled to the other end and has an approximately H shape.

A hand grinder H is mounted on the horizontal plate 340 . The hand grinder H is mounted by fastening means such as bolt fastening or welding.

In addition, the mounting portion 300 is formed in the lower portion of the horizontal plate 340, the opening holes are formed on both sides of the fixing block 360 having a passage formed therein; A screw shaft 370 that penetrates through the fixing block 360 by screwing, one end is coupled through the front plate 330 and the mounting plate 320 and the rear end is coupled through the rear plate 350; It is configured to further include a handle 380 attached to the rear end of the screw shaft 370 .

The handle 380 rotates the screw shaft 370 so that the fixed block 360 can be moved forward or backward, and the horizontal plate 340 connected to the fixed block 360 is moved by moving the horizontal plate 340 . Since the mounted hand grinder (H) can be moved forward and backward, it is possible to adjust the distance from the work object (P).

The lifting unit 400 includes a gear coupled to the lifting screw 420, a motor 410 for rotating the gear forward and reverse, and a switch S for controlling on/off of the motor 410, and the It consists of a main body 430 connected to the horizontal moving bar 240 .

The gear is rotated by the rotation of the motor 410 , and the body 430 is lifted by the rotation of the gear along the lifting screw 420 , thereby adjusting the height of the horizontal moving bar 240 .

The mounting unit 300 includes an inverting unit 500 for inverting the position of the hand grinder (H).

As shown in FIGS. 6A to 7 , the inversion part 500 is formed at the lower portion of the front plate 330 and the mounting plate 320 through the central axis 510 and the mounting plate 320 . A hinge bracket 520, a protrusion 332 protruding from the lower portion of the front plate 330 to which the hinge bracket 520 is fitted, and a hinge shaft 540 coupled through the hinge bracket and the protrusion 332 ), and is screwed to the hinge bracket and configured to include a stop pin 550 in close contact with the hinge shaft 540 .

After releasing the stop pin 550 to be spaced apart from the hinge shaft 540, the holder 300 is rotated downward with the hinge shaft 540 as a rotation point to change the direction vertically so that the grinder blade faces upward ( 6b).

Thereafter, after rotating the hand grinder (H) downwards and holding the position horizontally again, the stop pin 550 is tightened so that it is in close contact with the hinge shaft 540 to be in a locked state (see FIG. 7 ).

On the other hand, as shown in Figures 1 and 5, is formed on the vertical moving bar 220, the pedestal 120 and the spacing maintaining portion 600 supported; includes.

The distance maintaining unit 600 is to be able to set the distance and the vertical angle between each side of the vertical moving bar 220 and the pedestal 120 to be mutually equal.

The gap maintaining unit 600 includes a fixed body 620 coupled to the vertical moving bar 220, and a probe 640 screwed to the fixed body 620 and having a tip in contact with the pedestal 120. consists of including

A band 660 is attached to the fixed body 620 , and the band 660 is wound and attached to the outer circumferential surface of the guide tube body 140 .

The probe 640 may have a pointed tip 641 and a driver groove formed at the rear end to couple the driver, or a hexagonal head may be formed at the rear end to be pinched with a wrench.

Therefore, by advancing the probe 640 so that the tip touches the pedestal 120, an appropriate separation distance of the vertical moving bar 220 can be set.

In this way, when the probes of each of the spacing maintaining units 600 provided on the upper and lower sides of both sides contact the pedestal 120, the same spacing and verticality can be equally maintained.

Hereinafter, the operation of the above-described embodiment of the present invention will be described.

An iron plate, which is a work object, is placed on the pedestal 120 .

Thereafter, the hand grinder H is mounted on the mounting unit 300 .

Thereafter, the grinding operation is performed while riding the horizontal moving bar 240 of the positioning unit 200 and moving the mounting unit 300 to reciprocate in the x-axis direction of the hand grinder H.

In addition, by manipulating the switch of the lifting unit 400 to move the lifting unit 400 to which the horizontal moving bar 240 is attached in the vertical direction, the grinding operation is performed while adjusting the height.

On the other hand, since the upper or lower part of the work object (P) has a blind spot where the hand grinder (H) does not reach, by using the inversion part 500 to reverse the position of the hand grinder (H) and place it, the grinding work is carried out to the blind spot can be
