Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 and 2, an embodiment of the present application provides an automated welding clamping device, which includes a base 1, a chuck 2, a lift pin 5, and a clip 4. The clamping device comprises a base 1 and a top rod 5, wherein a hinged portion 12 is arranged at one end of the base 1, the middle portion of a clamping head 2 is hinged to the hinged portion 12, the top rod 5 is connected to the other end of the base 1 in a sliding mode, a hinged seat 10 is fixed on the top rod 5, the clamping device further comprises a hinged piece 7, two ends of the hinged piece 7 are hinged to the hinged seat 10 and one end of the clamping head 2 respectively, and a clamping piece 4 is fixed to the other end of the clamping head 2 through a bolt 3. The clamping heads 2 are symmetrically arranged in two by taking the axis of the ejector rod 5 as a symmetry line, and each clamping piece 4 is arranged on each clamping head 2. One end of the mandril 5, which is far away from the hinged seat 10, is provided with a limiting part 51, and an elastic part is arranged between the limiting part 51 and the base 1. The elastic piece is a spring 6, and the spring 6 is sleeved on the ejector rod 5. Articulated seat 10 includes stiff end and sets up the hinge hole in stiff end both sides, articulated elements 7 passes through articulated shaft 8 and articulates in the hinge hole, the stiff end passes through nut 9 to be fixed on ejector pin 5.

When the clamping device is used, the clamping device is fixed on an operation table board, the air cylinder on the operation table board pushes the ejector rod 5 to move towards the direction of the chuck 2, so that the hinge base 10 is driven to move, the distance between the two hinge parts 7 and one end, hinged with the chuck 2, of each hinge part is reduced, and therefore the two clamping pieces 4 arranged on the chuck 2 are opened under the lever principle.

The manipulator that sets up on operation mesa gets the work piece and arranges in between two clamping pieces 4, and the cylinder returns after that, and ejector pin 5 kick-backs under the elasticity of spring 6, and two clamping pieces 4 draw close each other and carry the work piece, and in order to improve work efficiency, this clamping device can set up a plurality ofly on table surface, and a plurality of clamping device rotate to the below that sets up the bonding tool on table surface along with table surface in proper order to realize the welding of work piece.

The mode has the advantages of simple structure, reasonable design and high working efficiency.

On the basis, each clamping piece 4 is provided with a crescent-shaped clamping opening, and the crescent-shaped clamping openings form an oval clamping opening for clamping a workpiece.

It should be noted that during clamping, the diameter of the workpiece needs to be smaller than the major axis diameter of the oval-shaped clamp opening and larger than the minor axis diameter of the oval-shaped clamp opening. Therefore, when the clamping device works, the two clamping pieces 4 are close to each other, so that the short shaft edge of the elliptical annular clamping opening is abutted against a workpiece, and meanwhile, the workpiece cannot exceed the long shaft edge of the elliptical clamping opening, so that the clamping of workpieces with different sizes can be realized.

By the mode, workpieces with different sizes in the range can be clamped, so that clamping and welding of various workpieces can be met.

On the basis, the base 1 is provided with the square sliding groove 11, the ejector rod 5 is arranged to be in a square column shape matched with the square sliding groove 11, and the square column-shaped ejector rod 5 is connected in the square sliding groove 11 in a sliding mode.

When the square-column-shaped ejector rod 5 slides in the square sliding groove 11, four limiting surfaces of the square sliding groove 11 limit four surfaces of the square-column-shaped ejector rod 5.

Through the arrangement of the square sliding groove 11 and the square column-shaped ejector rod 5, the ejector rod 5 is more smooth and stable when sliding and is not easy to axially rotate.

The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention.
