Figs. 5A and 5B are views showing a separation process between the shaft and the shaft cover. Fig.

1 to 5B, the fixing jig 1 according to an embodiment of the present invention is composed of a shaft 10, a pair of shaft covers 20 and 20 ', and a locking means 40.

The pair of shaft covers 20 and 20 'are detachably fixed to both ends of the shaft 10.

The shaft 10 is a rod that can insert the base material M (see FIG. 1).

For example, a plurality of base materials M (see FIG. 1) are inserted into the shaft 10 and are pressed and fixed to each other by a pair of shaft covers 20 and 20 ' M can maintain a fixed state even when the shaft 10 and the pair of shaft covers 20 and 20 'roll (rotate).

A coupling member 25 of one shaft cover 20 is coupled to an inner circumferential surface of one of the insertion grooves 13 at one end thereof The connector 41 and the fixing member 44 of the locking means 40 are inserted into the inner circumferential surface of the other side insertion groove 13 so as to be inserted into the fixing member 44, And an engaging groove 14 in which an end portion of the engaging groove 14 is removably mounted.

The shaft covers 20 and 20 'are detachably attached to both ends of the shaft 10 to press and fix a plurality of base materials M fitted to the shaft 10, It should be noted that the coated ceramic paste is dried in a uniformly applied state.

The shaft cover 20 is integrally formed with a disk-shaped wheel 24 and a seating portion 22 and a fastening member 25 formed on both sides of the wheel 24 with reference to the wheel 24.

6 and 7) of the chain 102 (see Figs. 6 and 7), and the wheel 24 is rotatably mounted on the frame 101 And the fastening member 25 is fastened to the one insertion portion 21 of the shaft 10. [

The shaft cover 20 'includes a disk-shaped wheel 24, a seat 22 integrally formed on one side of the wheel 24, and a wheel 24 formed in the center of the seat 24 and the seat 22 An insertion portion 21 is formed.

One end of the bar 42 passes through the insertion part 21 and is exposed to the outside so that an operator can press one end of the exposed bar 42. [

6 and 7) of the chain 102 (see Figs. 6 and 7), and the wheel 24 is rotatably mounted on the frame 101 6) and rolls on the bottom surface.

In the present embodiment, the shaft cover 20 'is detachably mounted on the other side of the shaft 10 via the locking means 40.

2 to 5B, the locking means 40 includes a connector 41, a bar 42, a spring 43 and a fixing member 44. In this embodiment, the shaft cover 20 ' And serves to detachably connect the shaft 10 and the shaft cover 20 'to each other.

The connector 41 is a tube having an inner side opened to one side and a receiving groove 41a for receiving one end of the bar 42 and a spring 43 is formed therein and a fixing member 44 is provided at the center of the peripheral surface. And a screw is formed on one side of the outer circumferential surface so as to be screwed into the inner circumferential surface of the insertion portion 21 of the shaft cover 20 '.

In the present embodiment, the connector 41 is fastened to the insertion portion 21 of the shaft cover 20 '.

The bar 42 is movably received in the receiving groove 41a of the connector 41 and the insertion portion 21 of the shaft cover 20 'as a rod, and a part of the bar 42 penetrates through the shaft cover 20' Lt; / RTI >

In particular, one end of the bar 42 is integrally formed with a guide groove 42a which is inclined upward from one end to the other end. The guide member 42a has a ' And moves up and down while moving along the groove 42a.

The spring 43 is a coil spring which is housed in the receiving groove 41a of the connector 41 of the present embodiment and functions to push the bar 42 in one direction.

For example, when the bar 42 exposed to the outside is pressed, the spring 43 is compressed. When the pressurized state is released, the restoring force of the spring 43 returns the bar 42 to its original state.

The fixing member 44 is a member having an elliptical shape and is movably coupled to the guide groove 42a in the present embodiment and penetrates through the coupling hole 41b of the connector 41, And is detachably coupled to the engaging groove 14.

4 and 5, in the present embodiment, when the wheel 24 of the shaft cover 20, 20 'is brought into contact with the bottom surface of the frame 101 of the molding machine 100, 24, the wheel 24 naturally rolls. Therefore, the ceramic paste applied to the base material M is naturally dried without being flowed and uniformly applied to the base material M while maintaining the condition.

Therefore, according to the present embodiment, it is possible to solve the problem that the ceramic paste is concentrated on one side as it flows down, thereby reducing the product defective rate and maximizing the productivity.

The mutual relationship between the shaft 10, the shaft cover 20 'and the locking means 40 will be described in detail as follows.

5A and 5B, when one end of the bar 42 exposed to the outside through the shaft cover 20 'is pressed, the bar 42 is inserted into the receiving groove 41a of the connector 41 So that the spring 43 is pressed in this process.

As the bar 42 moves in this manner, the fixing member 44 coupled to the guide groove 42a is moved along the inclined surface of the guide groove 42a, whereby the fixing member 44 is gradually lowered The shaft 10 and the shaft cover 20 'are disengaged from the engagement groove 14 of the shaft 10 so that the shaft 10 and the shaft cover 20' ) Is naturally detachable.

Then, the shaft 10 and the shaft cover 20 'are separated from each other. At this time, when the pressing state of the bar 42 is gradually released, the spring 43 pushes the bar 42 by the restoring force The bar 42 is restored to the initial state and the fixing member 44 is moved up and down along the guide groove 42a of the bar 42 while moving upward.

Therefore, according to the present embodiment, since the shaft 10 and the shaft cover 20 'are connected to each other through the locking means 40, there is an advantage that they can be easily and easily separated and combined.

If the circumferential surface of the wheel 24 is smooth, slip may occur on the bottom surface of the frame 101 of the molding machine 100. Thus, the shaft covers 20 and 20 ' There may be a serious problem that the ceramic paste flows downward and is biased to one side, resulting in a marked increase in the product defective rate.

In this embodiment, the circumferential surface of the wheel 24 is knurled to solve the problem.

Thus, according to the present embodiment, by knurling the circumferential surface of the wheel 24 as described above, it is possible to increase the frictional force between the wheel 24 and the bottom surface of the frame 101, The smooth rolling motion of the wheel 24 can be induced, thereby minimizing the above-mentioned problem caused by slip.

For reference, the knurling process can be variously shaped, so its shape is not limited.

Hereinafter, the operation of the present invention will be described.

6 and 7 are views for explaining the operation of the fixing jig for a ceramic coating apparatus according to the present invention.

6, a chain 102 having a bracket 102a is provided at both ends of a frame 101 of a molding machine 100. The chain 102 is engaged with a sprocket (not shown) .

When the seating portion 22 of the fixing jig 1 according to the present invention is placed on the bracket 102a of the molding machine 100, the wheels 24 of the shaft covers 20, 20 ' It will be placed on the surface.

7, when the chain 102 is moved, the shaft 10 and the shaft covers 20 and 20 'and the shafts 20 and 20' are smoothly moved due to the frictional force between the bottom surface of the frame 101 and the wheel 24. [ 10 and the base material M on which the ceramic paste is applied on the outer surface, roll together.

Accordingly, the ceramic paste applied to the base material M is naturally dried while keeping the condition that the ceramic paste is uniformly applied to the base material M without flowing.

Particularly, the circumferential surface of the wheel 24 is knurled to increase the frictional force between the wheel 24 and the bottom surface of the frame 101, thereby inducing smooth rolling motion of the wheel 24 The occurrence of slip can be minimized.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the same is by way of illustration and example only and is not to be construed as limited to the specific embodiments set forth herein; rather, .
