Description

Adjustable clamping device

The present invention relates to an apparatus for adjusting a jig, and more particularly to a holding device capable of reducing jigs of different sizes and maintenance costs.

In modern technology products, such as testing equipment for liquid crystal display (LCD) and general processing equipment, it is necessary to hold objects of different sizes and specifications. At present, a clamping fixture mechanism has been developed. Referring to Fig. 1, a clamping mechanism for designing a clamp for replacing a movable end is designed according to the size of the web. As shown in Fig. 1, the web 1' is 18X18 in size, and the web 1 is held by the movable end jig 3' in cooperation with the fixed end jig 2'. When replacing the web 4' having a size of 50X50, as shown in Fig. 2, it is necessary to replace it with the movable end jig 5'.

The disadvantage of the prior art is that it is necessary to design movable end fixtures of different specifications according to the size of the material pieces, and the total number of jigs is large and the management is not easy. Moreover, the fixture needs to be recalibrated when it is replaced, so there will be a long replacement time.

SUMMARY OF THE INVENTION The object of the present invention is to provide an apparatus for adjusting a jig that does not require replacement of different jigs, reduces the time for replacing the jig, and recalibrates the adjustment time, and can quickly and accurately locate the function.

Therefore, the adjustable clamping device of the present invention comprises: a fixed end clamp; a movable end clamp engaged with the fixed end clamp to clamp an object; a connecting rod fixed to the movable end clamp, and an adjustment a piece of joint; wherein the fixing position of the connecting rod and the adjusting piece is adjusted according to the specification of the object.

Preferably, the adjusting member is an adjusting block, and the adjusting block is provided with a first slider for moving the adjusting block.

Preferably, a second slider is arranged under the movable end clamp for moving the movable end clamp. The first slider and the second slider are mounted on the same track.

Preferably, the adjusting block is provided with a plurality of adjusting holes in a row, and a screw is inserted through one of the adjusting holes to fix the connecting rod and the adjusting block.

The utility model has the advantages that the specification of the jig is reduced by the adjustable clamping device, the maintenance cost can be greatly reduced, and in the process, the problem that the size of the material piece is different, the different jig needs to be replaced, and the problem is reduced Change the fixture and recalibrate the adjustment time to make it quicker and more precise.

The above and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments.

Referring to FIG. 3 and FIG. 4, a preferred embodiment of the adjustable clamping device of the present invention comprises a slider 1, a track 2, a slider 3, a connecting rod 4, an adjusting block 5, and a fixed end clamp. 6 and a movable end clamp 7.

The fixed end clamp 6 is fixed to the device of the adjustable jig and cooperates with the movable end clamp 7 to hold all the articles of different sizes. The slider 1 and the slider 3 are mounted on the same rail 2, and the slider 1 is mounted with an adjustment block 5 on which the movable end clamp 7 is mounted. The connecting rod 4 is fixed to the movable end jig 7 and coupled to the adjusting block 5.

Referring to FIG. 5 and FIG. 6, the adjusting block 5 is provided with a plurality of adjusting holes 45 in a row, and the adjusting holes 45 are designed according to the size of the web. According to the required fixture specifications, the adjustment hole 45 at an appropriate position on the adjustment block 5 can be screwed through, and the connecting rod 4 and the adjustment hole 45 can be fixed to change the different size specifications of the clamped object.

It can be seen from the above that the invention reduces the specification of the jig by the adjustable clamping device, and the maintenance cost can be greatly reduced. In the process, the problem that the different jigs need to be replaced due to different size specifications of the material piece is solved. Moreover, the time for replacing the jig and recalibrating the adjustment is reduced, and the positioning can be performed more quickly and accurately, so that the object of the present invention can be achieved.

The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All remain within the scope of the invention patent.
