Meanwhile, because the connecting piece 30 is in clearance fit with the first connecting hole 121, a certain clearance is formed between the connecting sleeve 12 and the connecting piece 30, so that the pressing plate 11 can float and/or swing relative to the lifting rod 21, and the structure is simple and convenient to realize.

In a specific design, the spacing between the limiting step 213 and the connecting sleeve 12 may be selected and designed according to actual use requirements, which is not specifically limited in the embodiment of the present application.
Optionally, in some embodiments of the present application, the angle of the swing of the platen 11 along the length direction of the lifting rod 21 is not greater than 2 °, that is, as shown in fig. 7, the swing angle a of the platen 11 is not greater than 2 °, when the swing angle a of the platen 11 is greater than 2 °, the platen 11 is too large to buffer, so that it is difficult to clamp the workpiece on the assembly line, that is, the embodiment of the present application not only can well compensate for errors between the workpieces, but also stably press and fix the workpiece on the assembly line by making the angle of the swing of the platen 11 along the length direction of the lifting rod 21 not greater than 2 °.
Referring again to fig. 1-4, the compression assembly 10 of the present embodiment further includes a reset member 13, the reset member 13 being configured to reset the connection sleeve 12.

In actual operation, once the connecting sleeve 12 floats and/or swings in the process of pressing down the workpiece, after the workpiece is processed, the lifting rod 21 rises upwards, and when the pressing assembly 10 is driven to move towards a direction away from the assembly line, the connecting sleeve 12 and the pressing plate 11 can be driven to reset through the action of the elastic piece 132, so that the next use is facilitated.
Alternatively, the elastic member 132 is a spring, an elastic sleeve, an elastic pad, or the like, and the case where the elastic member 132 is a spring is shown in the drawings in this embodiment. In actual installation, the elastic member 132 may directly abut against the connecting sleeve 12, or may indirectly abut against the connecting sleeve 12.
In an exemplary embodiment of the present application, the restoring member 13 further includes a sleeve 134, where the sleeve 134 is sleeved on the lifting rod 21 and is located on a side of the gasket 131 near the connecting sleeve 12, the sleeve 134 abuts against the top end of the connecting sleeve 12, an outer flange 1341 is disposed on the sleeve 134, and the elastic member 132 is sleeved on the sleeve 134 and abuts between the outer flange 1341 and the gasket 131. So set up, after work piece processing is accomplished, lifter 21 rises upwards, drives when compressing tightly subassembly 10 to be kept away from the assembly line direction motion, through the effect of elastic component 132, also can drive adapter sleeve 12 and clamp plate 11 to reset. In this embodiment, by providing the sleeve 134, the restoring force applied by the elastic member 132 can be well and stably transferred to the connecting sleeve 12, and the pressing plate 11 connected with the connecting sleeve 12 is kept parallel to the assembly line by using the sleeve 134, so that the structure is stable and convenient to implement.

When the piston rod rotates relative to the cylinder 22, the position of the pressing plate 11 can be adjusted, and then the pressing plate 11 can be rotated to the upper part of the production line, so that the pressing plate 11 can be accurately pressed down on a workpiece after being lowered.
Specifically, the driving assembly 20 further includes a guide 23 and a spiral groove 24, wherein the guide 23 is disposed on one of the piston rod and the cylinder 22 and is inserted into the spiral groove 24, and the spiral groove 24 is disposed on the other of the piston rod and the cylinder 22, that is, when the guide 23 is disposed on the cylinder 22, the spiral groove 24 is disposed on the piston rod; when the guide 23 is provided on the piston rod, the spiral groove 24 is provided on the cylinder 22. When the piston rod stretches and contracts relative to the cylinder body 22, the guide piece 23 slides along the spiral groove 24, and then the piston rod can be driven to rotate relative to the cylinder body 22, and the structure is simple and convenient to realize.
Alternatively, the guide 23 in the embodiment of the present application is a guide pin or a guide protrusion or the like.
