In this embodiment, the floating support 4 is provided with four groups, and is arranged opposite to each other in pairs, and each group of floating support 4 includes two elastic members 42, and the elastic members 42 are springs, and one end of the support rod 41 is fixedly connected to the bottom plate 12, such as welding or threaded connection, and is perpendicular to the bottom plate 12.

[0030] In an optional embodiment, if Figure 1As shown, the floating positioning clamping assembly 3 further includes a main board 33 and a first slider 34. The main board 33 is vertically arranged relative to the bottom plate 12, and its end is connected to the support rod 41 through the first slider 34.

[0034] In an optional embodiment, if Figure 4 As shown, the pressure head 21 is a stepped structure, and each stepped end surface of the pressure head 21 is provided with a magnetic attraction member 5 for adsorbing the oil pipe joint. Specifically, the pressure head 21 is connected with the oil pipe joint in cooperation with the magnetic attraction member 5, so that the pressure head 21 and the oil pipe joint are stably connected, and after the press-fitting is completed, the oil pipe joint can be easily separated from the pressure head 21 under the restriction of the workpiece.

[0035] In an optional embodiment, if Figure 2 As shown, the floating press assembly 2 further includes a second slider 24, which is movably sleeved on the support rod 41, and the top plate 11 is connected to the circumference of the second slider 24.

Specifically, the top plate 11 is provided with a hole corresponding to the second slider 24, and the second slider 24 is a cylindrical structure, and one end thereof radially extends to form a connecting plate 241. The second slider 24 is sleeved on the circumference of the support rod 41 and is connected to the top plate 11 through the connecting plate 241. In the process of the top plate 11 descending, the end of the support rod 41 can pass through the hole of the top plate 11 to achieve the descending of the top plate 11.

[0036] In an optional embodiment, if Figure 1 As shown, it also includes a limiting chain 6, one end of which is connected to the top plate 11, and the other end is connected to the bottom plate 12.

[0037] In an optional embodiment, if Figure 1 As shown, the control valve 8 is also included, and the control valve 8 is used to control the top plate 11 to press the workpiece. The control valve 8 is a manual valve, and the second slider 24 uses the external air source as a driving source. The control valve 8 is arranged between the second slider 24 and the external air source and is connected through a pipeline. The staff can open or close the passage between the second slider 24 and the external air source through the control valve 8 to achieve the purpose of controlling the operation of the second slider 24.

[0038] When no processing operation is performed, the top plate 11 is located at the farthest position from the bottom plate 12. First, the oil pipe joint is adsorbed on the pressure head 21, and then the hole position of the workpiece is aligned with the positioning pin 311 and placed, and the end face of the workpiece is fitted with the main board 33, and part of the circumference of the workpiece is fitted with the arc surface 321 of the support seat 32. The angle cylinder 313 is further used to drive the pressure block 312 to press the workpiece, so as to achieve rapid positioning and stable installation of the workpiece. At this time, the position of the workpiece to be pressed is aligned with the oil pipe joint, and the control valve 8 is opened, so that the second slider 24 is driven by the external air source to drive the top plate 11 to move toward the bottom plate 12, and under the influence of the elastic member 42, floating press fitting is achieved between the oil pipe joint and the workpiece. After the press fitting is completed, the external air source is disconnected by the control valve 8, and the first slider 34 is restricted by the rebound force of the elastic member 42 and the limit chain 6, and drives the top plate 11 back to the initial position.

[0039] To summarize, the device positions and places the workpiece and floats the oil pipe joint by using the floating press-fitting assembly 2 and the floating positioning clamping assembly 3, and at the same time increases the force points of the workpiece by providing a support portion and a positioning pin 311, thereby preventing the floating press-fitting assembly 2 from tilting up at one end of the workpiece during the press-fitting process, increasing the press-fitting depth, improving the press-fitting effect, and further improving the anti-leakage performance of the workpiece after press-fitting during use, thereby preventing leakage at the press-fitting position and reducing safety risks.
