[0021] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] like Figure 1 and Figure 2As shown, the first embodiment of the utility model proposes a connection device with positioning and locking functions, including a movable plate 10 and a fixed plate 20 matched with the movable plate 10, the movable plate 10 is provided with an expansion mandrel assembly 11 and a locking cylinder assembly 12, and the fixed plate 20 is provided with a positioning sleeve 21 corresponding to the expansion mandrel assembly 11, and a locking sleeve 22 corresponding to the locking cylinder assembly 12. In this embodiment, by using the expansion mandrel assembly 11 for positioning and then using the locking cylinder assembly 12 for locking, the working scene of the two connecting plates of the movable plate 10 and the fixed plate 20 being accurately positioned and the normal bearing capacity between the plates being large is achieved.

[0023] Further, see Figures 1 to 5 The present embodiment provides a connection device with a positioning and locking function. The expansion spindle assembly 11 includes a mounting box 111, a shaft core 112, a pull rod 113 and a positioning spring piece 114. The pull rod 113 passes through the mounting box 111 and is connected to the shaft core 112. The positioning spring piece 114 is sleeved on the shaft core 112. In the present embodiment, the positioning spring piece 114 is an annular spring piece. The positioning spring piece 114 has a plurality of open grooves 115 arranged evenly and staggered at both ends in the circumferential direction. The present embodiment provides a connection device with a positioning and locking function. The pull rod 113 moves to the left with the shaft core 112, causing the diameter of the positioning spring piece 114 to increase, thereby achieving a close fit with the positioning sleeve 21 and playing a role in precise positioning.

[0024] Preferably, see Figures 1 to 5 The connection device with positioning and locking function provided in this embodiment, the locking cylinder assembly 12 includes a locking cylinder body 121 and a shaft head 122 provided on the locking cylinder body 121. The locking sleeve 22 includes a locking shaft sleeve 221 and a groove 222 provided in the locking shaft sleeve 221 for matching with the shaft head 122. A locking spring piece 223 is provided between the shaft head 122 and the groove 222. The connection device with positioning and locking function provided in this embodiment, when the locking cylinder assembly 12 moves to the right, the shaft head 122 pushes the locking spring piece 223 to be tightly stuck in the groove 222 of the locking shaft sleeve 221, thereby realizing the relative position fixing between the movable plate 10 and the fixed plate 20.

[0025] like Figures 1 to 5 As shown, the connection device with positioning and locking function provided in this embodiment has the following working principle:

[0026] The expansion mandrel assembly 11 and the locking cylinder assembly 12 are fixed on the movable plate 10 , and the positioning sleeve 21 and the locking sleeve 22 are fixed on the fixed plate 20 .

[0027] Working state: When the movable plate 10 slowly approaches the fixed plate 20, the expansion mandrel assembly 11 extends into the positioning sleeve 21. After it is in place, the hydraulic system drives the expansion mandrel assembly 11 to work and fasten with the positioning sleeve 21 to achieve precise positioning. Next, the hydraulic system drives the shaft head 122 of the locking cylinder assembly 12 to work and tightly cooperate with the inner groove 222 of the locking sleeve 22 to achieve the locking of the movable plate 10 and the fixed plate 20.

[0028] Here's how the expansion mandrel works:

[0029] When the hydraulic system drives the pull rod 113 to move leftward, the pull rod 113 moves leftward with the shaft core 112. At this time, the shaft core 112 moves leftward, causing the diameter of the positioning spring 114 to increase, thereby achieving close cooperation with the positioning sleeve 21 and achieving precise positioning.

[0030] Working principle of locking cylinder:

[0031] When the hydraulic system drives the shaft head 122 of the locking cylinder assembly 12 to move rightward, the shaft head 122 pushes the locking spring piece 223 to be tightly clamped in the groove 222 of the locking sleeve 221 , thereby achieving the relative position fixation between the movable plate 10 and the fixed plate 20 .

[0032] Compared with the prior art, the connection device with positioning and locking function provided in this embodiment adopts a movable plate and a fixed plate matched with the movable plate, the movable plate is provided with an expansion mandrel assembly and a locking cylinder assembly, and the fixed plate is provided with a positioning sleeve corresponding to the expansion mandrel assembly and a locking sleeve corresponding to the locking cylinder assembly. The connection device with positioning and locking function provided in this embodiment is multifunctional, realizing precise positioning and locking functions; hydraulic drive, easy to automate; as a platform, it builds a structural platform to optimize pipeline layout and beautify on-site layout; it is convenient for on-site management and maintenance, realizing cost reduction and efficiency improvement; and the labor intensity of technical workers is reduced due to centralized management.
