Problems solved by technology
The mobile workbench moves until it hits the baffle and stops. Due to the collision, a certain collision force is generated, so that this structure cannot achieve accurate positioning, and it is inconvenient to replace, which is likely to cause unsafe factors for the operator. At the same time, the hydraulic press The appearance is not beautiful

Embodiment Construction
[0011] Further illustrate below in conjunction with this embodiment:
[0012] Such as figure 2 , Figure 3a , Figure 3c , Figure 4a , Figure 4c As shown, the lower plane 11 of the mobile workbench 10 and the upper plane 51 of the lower beam 50 are respectively provided with recesses 13, 53 on one side of themselves, and the cavity formed by the two recesses is used to accommodate a group of combined stoppers. Divided into upper and lower stop blocks 20,60, the cross-sectional shape of the upper and lower stop blocks 20,60 is stepped, and the two are lapped and matched. The lower plane 22 of the upper stop block 20 is lower than the upper plane 51 of the lower beam 50 and The upper plane 61 of the lower block 60 is higher than the lower plane 11 of the mobile table 10 , and the mobile table 10 and the lower beam 50 are respectively provided with air holes 14 , 54 communicating with the recesses 13 , 53 .
[0013] The upper stop block 20 is fixed in the recess 13 with f...

The invention relates to a positioning device, in particular to a positioning device applied to a transverse table of a large or medium-sized hydraulic press. A concave part is respectively arranged at one side of the lower plane of the transverse table and at one side of the upper plane of a lower separator, and a cavity formed by the two concave parts is used for holding a group of combined link stoppers which include an upper link stopper and a lower link stopper, and the upper link stopper and the lower link stopper are respectively connected with the concave parts. The lower plane of the upper link stopper is lower than the upper plane of the lower separator and the upper plane of the lower link stopper is higher than the lower plane of the transverse table. According to the technical proposal, in the invention, the link stoppers are respectively arranged on both the transverse table and the lower separator, thus realizing the positioning by virtue of the mutual contact of the stoppers; therefore, the structure has safe operation and beautiful shape as well as high positioning precision and convenient replacement.
Description
technical field [0001] The invention relates to a positioning device, in particular to a positioning device applied to a mobile workbench of a large and medium-sized hydraulic press. Background technique [0002] Currently known large and medium-sized hydraulic presses use a structure in which a baffle plate is installed outside the movable workbench of the hydraulic press to achieve positioning. The mobile workbench moves until it hits the baffle and stops. Due to the collision, a certain collision force is generated, so that this structure cannot achieve accurate positioning, and it is inconvenient to replace, which is likely to cause unsafe factors for the operator. At the same time, the hydraulic press The appearance is also not beautiful. Contents of the invention [0003] The object of the present invention is to provide a positioning device with high positioning accuracy, detachable and safe operation installed inside the large and medium-sized hydraulic press. ...
