1 to 3, a clamp device for fixing a test object according to a first embodiment of the present invention includes a crane pad, an airbag cover, a door trim, When the dimensions of the three-dimensional shape of the inspection object 100 and / or the parts 101 in the inspection object 100 are verified or the parts are mounted or not, And includes a fixed base 10, a fixed block 20, a guide lever 30, first and second clamp blocks 40 and 50, an operating portion 60, and a spring 70.

The fixed base 10 is provided with a test object 100 on which the component 101 protrudes and one or at least one of the fixed blocks 20 is disposed at a predetermined interval .

That is, the object to be inspected 100 may be a crash pad, an airbag cover, a door trim, an electric component panel, etc. formed with a screw boss, a hook or a clip type component 101, The size and shape of the fixed base 10 are changed according to the shape of the fixed base 10 and the fixed base 10 is fixed to the fixed base 20 in accordance with the number of the parts 101 protruding from the inspected object 100 Or a plurality of fixed blocks 20 may be arranged at regular intervals.

A guide block 21 for guiding the linear movement of the first clamp block 40 and a guide hole 22 for seating the spring 70 are formed on the fixed block 20, As shown in FIG.

The guide lever 30 is coupled to the fixed block 20 so as to be rotatable about a hinge h and linearly moves the first and second clamp blocks 40 and 50 at both ends thereof The first and second guide projections 31 and 31 'are protruded.

The first clamp block 40 has a first flow groove 41 in which the first guide protrusion 31 is seated and linearly moves according to the rotation of the guide lever 30, And a fixing hole 42 for fixing the component 101 protruding from the fixing hole 42 is formed.

Here, the size of the fixing hole 42 is such that the component 101 has an opening area through which the component 101 can be inserted without interference.

The second clamp block 50 linearly moves so as to rotate the guide lever 30 while having a second flow groove 51 in which the second guide projection 31 'is seated, The opening area of the fixing hole 42 can be adjusted according to the linear movement of the block 50.

That is, when the second clamp block 50 is linearly pulled by the actuating part 60 in the first direction P1, the guide lever 30 rotates counterclockwise, The first clamp block 40 linearly moves in the second direction P2 opposite to the first direction P1 of the second clamp block 50 from the counterclockwise rotation of the first clamp block 50, The opening area of the block 40 with respect to the fixing hole 42 is widened so that the component 101 can be fitted into the fixing hole 42.

On the other hand, the second clamp block 50 is returned in the second direction P2 opposite to the first direction P1 by the elastic force of the spring 70 when the pulling by the actuating part 60 is released The guide lever 30 rotates in the clockwise direction and the first clamp block 40 rotates in the second direction P2 of the second clamp block 50 from the clockwise rotation of the guide lever 30 A part of the distal end side of the second clamp block 50 closes a part of the fixing hole 42 of the first clamp block 40 while the second clamp block 50 is linearly moved in the first direction P1, The opening area of the fixing hole 42 is narrowed so that the component 101 of the inspected object 100 inserted into the fixing hole 42 can be securely fixed.

The actuating part 60 is connected to the second clamp block 50 and linearly moves in the first direction P1 while pulling the second clamp block 50. The second clamp block 50, And an operating lever 62 which is rotated to pull the operating wire 61. The operating wire 61 is connected to one side of the operating wire 61,

The operation lever 62 includes a handle lever 62a and a rotation lever 62b that is orthogonal to the handle lever 62a. The rotation lever 62b has one end fixed to the fixed bracket 62a through a hinge h, And the other end of the rotation lever 62b is rotatably connected to one end of a connecting rod 64 which is linearly moved when the rotation lever 62b is rotated, by a hinge h, The operation rod 65 is connected to the other end of the connection rod 64 through a hinge h so that the operation rod 61 is connected to the operation rod 65.

At this time, a latching rod 61a is formed at the end of the operating wire 61 and a seating groove 52 is formed at one side of the second clamping block 50 to receive the latching rod 61a .

The spring 70 is connected at both ends to the fixed block 20 and the second clamp block 50 so that when the pulling action of the actuating part 60 is released, And is linearly moved in the second direction P2 opposite to the first direction (P1).

As described above, the clamping device for fixing an object according to the embodiment of the present invention is configured such that, as shown in Figs. 1 to 7, first, the dimensions of a three-dimensional shape or whether a component is mounted on the fixed base 10 The object to be inspected 100 on which one or a plurality of parts 101 protrude is placed.

At this time, the operator rotates the rotation lever 62b through the handle lever 62a included in the operation part 60. [

4 and 5, the connecting rod 64 and the actuating rod 65 are linearly moved by the rotation lever 62b, and the actuating wire 61 connected to the actuating rod 65, The second clamp block 50 is linearly moved in the first direction P1.

At this time, when the second clamp block 50 linearly moves in the first direction P1, the second guide protrusion 31 'is coupled to the second flow groove 51 of the second clamp block 50 The guide lever 30 is rotated counterclockwise.

The first guide protrusion 31 of the guide lever 30 is coupled to the first flow groove 41 of the first clamp block 40 so that the first clamp block 40 is in contact with the guide lever 30 30 linearly move in a second direction P2 opposite to the first direction P1 as the first and second rotating bodies 30, 32 rotate counterclockwise.

As the opening area of the fixing hole 42 formed in the first clamp block 40 is widened, the part 101 of the object to be inspected 100 can be easily inserted into the fixing hole 42 It is.

6 and 7, when the operator returns the operation lever 62 to its original position, the pulling action of the second clamp block 50 by the operation lever 62 is released The second clamp block 50 is linearly moved in the second direction P2 by the elastic force of the spring 70. As a result,

At this time, the guide lever 30 connected to the second clamp block 50 and the second guide protrusion 31 'rotates in the clockwise direction and the guide lever 30 The first clamp block 40 connected to the first clamping block 31 of the first clamp block 40 linearly moves in the first direction P1 while the tip end of the second clamp block 50 is connected to the first clamp block 40 The opening area of the fixing hole 42 is narrowed.

Therefore, the component 101 inserted into the fixing hole 42 can be maintained in a rigid fixed state without flowing, and the inspection object 100 can be fixed to the fixing base 10 It is possible to precisely measure or inspect the three-dimensional shape or mounting state of the inspection object 100 and / or the part 101 in the inspection object 100. [

When the worker pulls the second clamp block 50 again through the operation portion 60 after the inspection of the inspection object 100 is completed as described above, the second clamp block 50 The first clamp block 40 linearly moves in the first direction P1 and at the same time the guide lever 30 rotates in the counterclockwise direction and the first clamp block 40 is moved in the second direction opposite to the first direction P1 P2 so that the distal end of the second clamp block 50 moves away from the fixing hole 42 of the first clamp block 40 and the opening area of the fixing hole 42 widens again, The part 101 of the object to be inspected 100 can be easily separated from the fixing hole 42 of the first clamp block 40 without breakage.

Although the description of the clamping device for fixing the object according to the present invention has been described above with reference to the accompanying drawings, it is to be understood that the present invention is not limited thereto.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined by the appended claims. It is to be understood that such changes and modifications are within the scope of the claims.
