The support groove portion is formed integrally with a support groove into which the link lever of each link lever module is inserted, and each pin groove, which is connected to the support groove on both sides of the support groove and into which the pin coupled to each link lever is inserted.

The sliding groove includes a sliding groove in which each jaw is slidably connected, and a connecting hole formed on the sliding groove such that one end of each link lever is connected to each jaw.

The third plate includes a guide groove formed at a position where each jaw is slidably corresponding to the guide groove.

The plunger has an inlet groove formed in an upper portion of the link lever so as to be inserted therein, and a cylindrical body having a bottom surface fixed to the piston and extending from a lower portion of the inlet groove to a bottom surface contacting the piston.

In the present invention, the link lever module for rotating the jaws for chucking while being rotated by the plunger lifted by the piston is not pin-coupled through the perforations, but assembled by a simple assembly method for each unit unit while mounting the link lever module The link lever module can be easily assembled without troublesome or complicated work processes as well as the overall assembling operation of the link lever type air chuck can be performed quickly and easily in a short time, Effect.

In addition, since the overall volume can be made compact, it is easy to handle and can be installed easily in a narrow space.

1 is an exploded perspective view for explaining the present invention,
Figure 2 is a cross-sectional view of the combined state according to Figure 1,
3 is a cross-sectional view for explaining the use state of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings. The present invention is not limited to the embodiments.

FIG. 1 is an exploded perspective view for explaining the present invention, FIG. 2 is a sectional view of the combined state according to FIG. 1, and FIG. 3 is a sectional view for explaining the use state of the present invention.

As shown in the drawing, a link lever type air chuck 1 is used which is used for chucking to automate equipment such as various production lines, assembly lines, and the like to precisely process and prevent the flow of the workpiece.

The present invention relates to a link lever module which is rotated by a plunger lifted by a piston and which is operated by a plunger to move the jaws for chucking, So that the assembly can be performed.

The link lever module 20A is a well-known link lever module 20A. The link lever module 20A includes a link lever 20a, which is connected to a plunger at one end and to a jaw at the other end, And includes a pin 20b which is engaged.

A link lever type air chuck (1) according to the present invention includes a case (10) having a conventional cylinder (12), a piston (14) and a plunger (16) Each of the support lever portions 24 is inserted into the upper surface of the case 10 so that the link lever module 20A is inserted into the upper surface of the upper portion of the case 10 so as to be connected to the lifting and lowering hole 22 formed by vertically penetrating the plunger 16, And a first plate 20, which is mounted by conventional bolting or the like.

A sliding groove 32 is formed in the upper portion of the first plate 20 so that a plurality of jaws 30A are slidably inserted into the upper portion of the first plate 20 so as to be connected to the link lever 20a of the link lever module 20A A second plate 30 mounted by conventional bolting or the like; And a third plate (40) mounted on the upper portion of the second plate (30) so that the plurality of jaws (30A) are slidably covered on both sides.

In other words, the link lever type air chuck of the present invention does not need to perform the drilling operation by drilling or the like in order to assemble the link lever module, but mounts the link lever module on the support groove portion formed on the first plate, So that the assembly can be easily carried out without inconvenience or inconvenience.

In addition, not only the link lever module having fluidity for chucking in the link lever type air chuck, but also the second plate and the third plate are stacked and mounted on each jaw, so that the condition that can be assembled easily and conveniently without inconvenience or inconvenience . That is, as each unit unit is sequentially stacked, it has an advantage that anyone can assemble easily and conveniently in a short time.

Accordingly, it is possible to omit the drilling operation for drilling the link lever module to assemble the link lever module, which is the longest operation time at the time of manufacturing or assembling the link lever type air chuck, and it is also possible to omit the post- Convenience and high efficiency.

Further, the overall assembly of the link lever type air chuck is also achieved by simply stacking and mounting the unit for each unit unit, so that the assembly efficiency and production efficiency can be maximized.

Accordingly, the present invention can be applied to a case in which a first plate is mounted on an upper portion of a case, a link lever module is mounted on the first plate, and a second plate and a plurality of jaws and a third plate are sequentially stacked on the first plate So that it is possible to manufacture and assemble easily and conveniently in a short time without inconvenience or inconvenience.

The support groove portion 24 is connected to the support groove 24a into which the link lever 20a of each link lever module 20A is inserted and the support groove 24a on both sides of the support groove 24a, And each pin groove 24b into which the pin 20b coupled to the pin 20a is inserted is integrally formed. The support groove portion is formed at the same time when the first plate is machined, thereby providing convenience in that it can be manufactured easily and conveniently.

The sliding groove portion 32 includes sliding grooves 32a to which the jaws 30A are slidably connected and one end of each link lever 20a on the sliding groove 32a, And the connection hole 32b is formed so as to be connected to the groove formed in the connection hole 32b. And the sliding groove portion is formed at the same time when the second plate is machined, thereby providing convenience that can be made simple and convenient. The sliding groove prevents lateral fluidity when the jaws are slidably moved for chucking.

In addition, the third plate 40 includes guide grooves 42 formed at positions where the jaws 30A are slidably corresponding. The guide groove exposes only a part of the upper part of the jaw and is covered by the third plates on both sides of the guide groove so as to be in contact with the upper surfaces on both sides of the jaw so as to prevent the upper and lower fluidity at the time of sliding operation for jaw chucking.

The plunger 16 has an inlet groove 16a formed at an upper portion thereof so that one end of the link lever 20a is inserted therein and a bottom surface thereof is fastened and fixed to the piston 14 by conventional bolting, And a cylindrical body 16b extending from a lower portion of the piston 16 to a bottom surface contacting the piston 14. That is, in the conventional plunger, a step portion is formed in the lower portion of the lead-in groove so as to be in contact with the base ring for airtightness with the piston, and the height of the plunger is limited by the step height. As a result, the overall height of the conventional link lever type air chuck becomes high and the volume becomes large.

The plunger of the present invention is formed in a cylindrical body from the lower part of the inlet groove so as to maintain the airtightness and the airtightness provided on the first plate without a single step, It has the condition that it can have the maximum value as compared with the condition that the volume can be minimized.
