Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a floating mechanism capable of simultaneously pressing four surfaces. Background Art

[0002] In welding fixtures, the space is small, and often one surface needs multiple pressure points to clamp the workpiece. The conventional mechanism uses multiple cylinders to press the required clamping positions separately, which requires more space, and one cylinder has multiple branch pressure points that are adjusted by gaskets. However, in this way, the workpiece is often clamped through line contact, which cannot ensure that the surfaces fit together. It seems to be clamped, but it is easy to damage the product. Therefore, a floating mechanism that can meet the requirements of simultaneous clamping of four surfaces is needed. Utility Model Content

[0004] To solve the above problems, the utility model adopts the following technical solutions.

[0005] A floating mechanism capable of simultaneously pressing four surfaces comprises a cylinder, the top of the cylinder is fixedly connected to a pressing arm, the right end of the pressing arm is hinged to a floating connection block, the bottom of the floating connection block is hinged to two mounting blocks, and two pressing blocks are installed at the bottom of the two mounting blocks.

[0007] A through slot is provided at the right end of the pressure arm, a hinge pin 1 is fixedly connected to the inner wall of the through slot, a block rotatably connected to the hinge pin 1 is sleeved on the hinge pin 1, and the bottom of the block is fixedly connected to the floating connection block.

[0008] As a further description of the above technical solution:

[0009] The bottom of the floating connection block is provided with two grooves, the inner walls of the two grooves are fixedly connected with hinge pins 2, and the tops of the two mounting blocks are respectively sleeved on the two hinge pins 2 and rotatably connected thereto.

[0010] As a further description of the above technical solution:

[0011] Two adjusting gaskets are installed at the bottom of the mounting block, and the two adjusting gaskets are respectively connected to the two pressing blocks.

[0012] As a further description of the above technical solution:

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] In this solution, a 1-2mm gap is reserved between the grooves and through grooves and the corresponding floating connection blocks and mounting blocks, so that the floating connection blocks and mounting blocks can rotate slightly in the corresponding grooves and through grooves, thereby making them float up and down. Two new pressure points are added, so that a set of four pressure points can ensure simultaneous surface contact and tightening, reduce pressure damage to the product, and ensure surface contact with the product.
