Detailed Description

In order to make the utility model realize that technical means, creation characteristics, achievement purpose and effect are clearer and easily understand, it is right to combine below the figure and the detailed implementation mode the utility model discloses do further explanation:

referring to fig. 1, for the utility model discloses an air jet clamping device, include slip table 1, be six anchor clamps 2 that a style of calligraphy was arranged on slip table 1. Before the air jet machine is processed, a workpiece is firstly clamped on the clamp 2, and then the clamp 2 clamped with the workpiece is sequentially pushed into an air jet device of the air jet machine by the sliding table 1 in a manual or mechanical structure driving mode.

The sliding table 1 comprises a first supporting plate 11, a first T-shaped groove 12 formed in the first supporting plate 11, a second supporting plate 13 connected to the first T-shaped groove 12 in a sliding manner, a second T-shaped groove 14 formed in the second supporting plate 13, and a base 15 connected to the second T-shaped groove 14 in a sliding manner. The length directions of the first T-shaped groove 12 and the second T-shaped groove 14 are vertical, and the length direction of the second T-shaped groove 14 is parallel to the arrangement direction of the clamp 2, so that the base 15 can move on a certain plane.

Referring to fig. 2, the clamping apparatus 2 includes a contact base 21 and a driving cylinder 22 disposed on the base 15, a positioning post 23 disposed on the contact base 21 and used for being inserted into a shaft hole of a workpiece, a positioning hole 24 opened on the positioning post 23, a mounting plate 25 disposed on a piston rod of the driving cylinder 22, a sliding rod 26 disposed on a surface of the mounting plate 25, five spring groups 27 disposed around the sliding rod 26, and a pressing plate 28 fixed on the spring groups 27 and slidably connected to the sliding rod 26. The driving cylinder 22 is used for driving the sliding rod 26 to slide and insert into the positioning hole 24, so that two end faces of the workpiece on the positioning column 23 tightly abut against the pressing plate 28 and the abutting seat 21.

During clamping, the shaft hole of the workpiece is firstly embedded with the positioning column 23, so that the workpiece can be temporarily placed on the positioning column 23, then the cylinder 22 is driven to drive the mounting plate 25 to move, and at the moment, the pressing plate 28 firstly abuts against the surface of the workpiece. The slide rod 26 is driven by the driving cylinder 22 to move continuously, and the spring set 27 compresses and reinforces the pressure of the pressing plate 28 on the workpiece, so that the workpiece is pressed between the pressing plate 28 and the abutting seat 21, and the slide rod 26 is inserted into the positioning hole 24 to play a positioning role and limit the pressing bias of the pressing plate 28.

The spring set 27 includes an inner compression spring 271 and an outer compression spring 272 sleeved outside the inner compression spring 271, and the spiral directions of the inner compression spring 271 and the outer compression spring 272 are opposite. By using the inner pressure spring 271 and the outer pressure spring 272 which are nested with each other, the elasticity of the spring set 27 is increased on the premise of not changing the length of the spring set 27, the structure is compact, and the pressure transmitted by the spring set 27 to the pressure plate 28 is further enhanced. Meanwhile, by using the inner compression spring 271 and the outer compression spring 272 which are reversely coiled, when the outer compression spring 272 is bent by external force, the outer compression spring 272 contacts the inner compression spring 271 and is reset by the reaction force of the inner compression spring 271, so that the position fixity of the inner compression spring 271 and the outer compression spring 272 is ensured, and the pressure of the spring group 27 is further improved.

In addition, two strip-shaped grooves 151 are formed in the base 15, four sliding blocks 211 which are connected into the two strip-shaped grooves 151 in a sliding mode are arranged on the abutting base 21, and bolts 212 which abut against the surface of the base 15 are connected to the sliding blocks 211 in a threaded mode. When the bolt 212 is screwed down, the sliding block 211 can be limited to slide or separate in the strip-shaped groove 151 due to the limit matching between the bolt 212 and the base 15 and between the abutting seat 21 and the base 15. After the bolt 212 is unscrewed, the pressure between the bolt 212 and the base 15 is reduced, so that the position of the abutting seat 21 on the strip-shaped groove 151 is convenient to move. After the bolt 212 is removed, the sliding block 211 can be separated from the strip-shaped groove 151, so that the abutting seat 21 and the positioning column 23 can be replaced conveniently, and the operation is simple and quick.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
