Description

A jig for fixing workpiece

The present invention relates to a work fixing jig having a new structure capable of easily fixing a workpiece.

Generally, various kinds of jigs used for fixing a workpiece for machining have been developed and widely used depending on the shape of the workpiece.

1 to 3 show a housing for a motor used for supporting a driving motor used in a washing machine and the like, among the work pieces fixed to the jig. The housing has a central portion protruding downward and a concave portion And a pair of extension portions 20 extending downward from both sides of the front edge of the main body 10, wherein the main body 10 is formed with through holes 11 passing through the upper and lower surfaces thereof, do.

At this time, a plurality of through-holes 12 are formed in the bottom surface of the main body 10 so as to have a circular shape with the through-hole 11 as a center.

A pair of protrusions 13 protruding outward are formed on both sides of the rear portion of the main body 10 and one protrusion 13 is formed through each of the protrusions 13 so as to penetrate the upper and lower surfaces.

A reinforcing rib 14 extending from the periphery of the through hole 11 to both sides of the fitting hole 13a is formed on the lower side of the main body 10, A pair of concave grooves 15 extending from the periphery of the through hole 11 to the engaging hole 13a are formed on the lower surface of the main body 10. [

The extension portion 20 is extended sufficiently downward so that the lower side is positioned lower than the lower side of the main body 10 and the engagement hole 21 Is formed.

On the other hand, in the case of a jig for supporting such a work A, there is provided an engaging pin which is engaged with the engaging holes 13a and 21 formed in the body 10 and the extending portion 20, So that the engaging holes 13a and 21 are engaged with each other.

However, in the case of such a jig, the joining pin, which is engaged with the engaging holes 13a and 21, is bent or abraded due to an external force generated when the work A is machined, making it difficult to accurately support the work A A problem has occurred.

Therefore, there is a need for a new method to solve such a problem.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Fig. 4 to Fig. 11 show a work fixing jig according to the present invention. The jig is fixed to the processing device for machining the work A to fix the work A, Do.

1 to 3, the central portion of the work A is protruded downward and the upper surface of the work A is formed with a concave portion 16 recessed downwardly. A through hole 11 penetrating the upper and lower surfaces is formed at the central portion. And a pair of extension portions 20 extending downward from both sides of the front edge portion of the main body 10. [

A plurality of through holes 12 are formed in the bottom surface of the main body 10 so as to have a circular shape with the through hole 11 as a center.

A pair of protrusions 13 protruding outward are formed on both sides of the rear portion of the main body 10 and one protrusion 13 is formed through each of the protrusions 13 so as to penetrate the upper and lower surfaces.

A reinforcing rib 14 extending from the periphery of the through hole 11 to both sides of the fitting hole 13a is formed on the lower side of the main body 10, A pair of concave grooves 15 extending from the periphery of the through hole 11 to the engaging hole 13a are formed on the lower surface of the main body 10. [

The extension 20 extends sufficiently downward so that the lower side of the extension 20 is located lower than the lower side of the main body 10 and the engagement hole 13a Is formed.

According to the present invention, the jig includes a support block 30 to which the workpiece A can be coupled, a support base 40 to which the support block 30 is fixed on the upper surface, And fixing means 50 for fixing the workpiece A fixed to the support block 30.

The upper end of the support portion 33 is provided with a step 33c having a concave downwardly inward to prevent the inner end of the upper end of the vertical portion 33b from interfering with the inner side surface of the recessed groove 15 .

9 and 10, when the workpiece A is placed on the support block 30, the lower surface of the main body 10, the extending portion 20, and the projecting portion 13, The engaging projections 32a are inserted into the through holes 12 and the vertical portions 33b of the supporting portions 33 are engaged with the engaging projections 32a, Is inserted into the concave groove (15) of the main body (10), and fixed so that the workpiece (A) does not move.

The support block 40 is formed in a disk shape and is coupled to a processing device for processing the workpiece A. The support block 30 is fixed to the upper surface of the support block 40 by a fixing bolt .

The fixing means 50 includes a support shaft 51 extending upward from the support 40 and a fixed arm 52 extending laterally from the tip of the support shaft 51 .

At this time, the fixing arm 52 is rotatably coupled to the upper end of the fixing means 50 in the lateral direction.

11, when the workpiece A is coupled to the support block 30 and then the fixation arm 52 is rotated in the lateral direction, the distal end of the fixation arm 52 is pushed by the support block 30, The upper surface of the work A bonded to the work 30 is fixed, and the work A is fixed so as not to move.

The work fixing jig having such a structure is provided with a support plate 31 on the support block 30 and a support protrusion 32 protruding upward from the upper surface of the support plate 31 to support the lower surface of the main body 10, And a pair of supporting portions 33 extending upward from the upper surface of the supporting plate 31 and supporting the lower side of the projecting portion 13 of the main body 10 of the processing member A. The supporting plate 31, The height h1 from the upper surface of the main body 10 to the upper surface of the supporting protrusion 32 is equal to the height h2 from the lower side of the extending portion 20 of the work A to the lower side of the main body 10 The lower surface of the main body 10 and the extended portion 20 and the protruding portion 13 is pressed against the support protrusion 32 and the support plate 31, And the upper surface of the support portion 33, respectively.

Particularly, an upper surface of the supporting protrusion 32 is formed with a coupling protrusion 32a to be inserted into and coupled with the through hole 12, and the upper inner circumferential portion of the supporting portion 33 is inserted into the concave groove 15 When the workpiece A is placed on the support block 30, the workpiece A is prevented from moving.

Unlike the conventional jig having the engagement pin inserted into the engagement hole 13a formed in the body 10 and the extension 20, the support block 30 and the workpiece A are in surface contact with each other Not only the workpiece A can be firmly fixed by fixing the workpiece A but also abrasion and deformation of each part do not occur even if used repeatedly so that the workpiece A can be fixed accurately There is an advantage.

In the present embodiment, the support block 30 and the support block 40 are separately configured. However, the support block 30 and the support block 40 may be integrally formed.
