[0026] In order to further illustrate the technical means and effects adopted by the present application to achieve the predetermined technical purposes, the specific embodiments, structures, features and effects according to the present application will be described in detail below in combination with the drawings and preferred embodiments.

[0027] The reference signs in the drawings of the specification include: a piston rod 1, a pressing block body 2, a connecting cylinder 3, a connecting cavity 4, a connecting groove 5, a mounting groove 6, an insertion block 7, an elastic friction block 8, a ring groove 9, a connecting block 10, and a limiting block 11.

[0028] The embodiments are shown in Figure 1 , Figure 2 and Figure 3 :

[0029] A corner oil cylinder pressing block includes a pressing block body 2, a connecting cylinder 3 fixed to one end of the pressing block body 2 for connecting a piston rod 1 in a corner oil cylinder, and a connecting cavity 4 arranged in the connecting cylinder 3 and rotationally connected with the connecting cylinder 3.

[0030] Regarding the pressing block body 2 and the connecting cylinder 3:

[0031] The pressing block body 2 and the connecting cylinder 3 are integrally forged into shape, and both the pressing block body 2 and the connecting cylinder 3 are provided with a fillet to avoid bumping. The forged shape can ensure the strength compared with welding.

[0032] Regarding the rotationally connected connecting cavity 4 and connecting cylinder 3:

[0033] For example, Figure 1 and Figure 3 ​As shown, the connecting cylinder 3 is provided with a ring groove 9, and the outer shaft of the connecting cavity 4 is fixedly connected with a connecting block 10, which slides in the ring groove 9 to realize the rotation of the connecting cavity 4 relative to the connecting cylinder 3, and the rotation of the connecting cavity 4 is realized;

[0034] Further comprising a plurality of connecting assemblies, which comprise an insertion body and connecting grooves 5 respectively provided on the connecting cylinder 3 and the connecting cavity 4, the connecting grooves 5 are uniformly arranged on the connecting cylinder 3 and the connecting cavity 4 with the cylinder center of the connecting cylinder 3 as the reference, the insertion body is connected and detached with the connecting grooves 5, and the connecting cylinder 3 is further provided with a dislocation assembly for preventing the dislocation installation of the connecting grooves 5 on the connecting cylinder 3 and the connecting cavity 4.

[0035] Regarding the dislocation assembly:

[0036] The dislocation assembly is composed of a plurality of limiting blocks 11, which are arranged in the ring groove 9, when the connecting block 10 contacts the limiting block 11, the connecting grooves 5 on the connecting cylinder 3 and the connecting cavity 4 are aligned and form an installation groove 6.

[0037] Specifically, as shown in the figure, Figure 2 The insertion body comprises an insertion block 7 and an elastic friction block 8, which are fixedly connected, the size of the insertion block 7 is equal to the size of the installation groove 6, and the elastic friction block 8 is compressed and squeezed into the gap between the piston rod 1 and the connecting cavity 4.

[0038] In order to ensure the strength of each metal, the material of the insertion block 7, the connecting cylinder 3, the connecting cavity 4 and the piston rod 1 is the same.

[0039] The elastic friction block 8 is a resin-based friction block, which ensures a certain elasticity and a high friction coefficient, since the elastic friction block 8 is compressed and squeezed into the gap between the piston rod 1 and the connecting cavity 4, in order to facilitate the connection of the elastic friction block 8, the contact surface of the resin-based friction block and the piston rod 1 is arc-shaped;

[0040] Specific implementation process:

[0041] First step, regarding the rotary oil cylinder: the piston rod 1 first completes the rotation stroke, the pressure arm is pressed down and rotated to the designed specified position and angle, and then completes the clamping stroke, i.e. straight-line pressing down and clamping the workpiece, for the pressure block, the pressure block body 2 also rotates first, and then straight-line presses down and clamps the workpiece, therefore, the connection between the piston rod 1 and the pressure block body 2 is crucial;

[0042] Second step, artificially rotating the connecting cavity 4 to align the connecting grooves 5 on the connecting cylinder 3 and the connecting cavity 4 and form an installation groove 6, this step can prevent misassembly, i.e. when the installation groove 6 is not formed, the insertion body cannot be connected, the advantage of this setting is that the insertion block 7 is not only connected to the cylinder of the connecting cavity 4, but also connected to the connecting cavity 4, which ensures the connection strength;

[0043] The third step adopts an independent insertion block 7 design, which ensures the integrity and overall strength of the piston rod 1 compared with the traditional piston rod 1 opening slot, the insertion block 7 is inserted into the mounting groove 6 as a whole, and the elastic friction block 8 is compressed and extruded into the gap between the piston rod 1 and the connecting cavity 4, so that the piston rod 1 is in contact with the elastic friction block 8. Because the piston rod 1 has a rotating motion, the elastic friction block 8 with high friction coefficient can effectively improve the connection stability.

[0044] Compared with the traditional piston rod 1 opening slot, the installation is more advantageous, the key groove connection is necessarily hammered into, that is, it is more troublesome to cooperate, the piston rod 1 is not modified in the case, and the piston rod 1 is the most basic shaft hole connection. The insertion block 7 is adopted, and because the size of the insertion block 7 is equal to the size of the mounting groove 6, the insertion of the insertion block 7 is also easier. At this time, only the redundancy, that is, the redundancy of shaking, is left. The elastic friction block 8 is provided in the case, the elastic friction block 8 is compressed and extruded into the gap between the piston rod 1 and the connecting cavity 4, which reasonably solves the redundancy of shaking, and can also utilize the friction force to offset the rotation of the piston rod 1, so that the installation is more stable.

[0045] The device solves the problem that the traditional pressing block and the extended end of the piston rod 1 cannot be quickly installed.

[0046] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with a preferred embodiment, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above disclosed technical content to make equivalent embodiments with equivalent changes, but as long as it does not deviate from the technical solution of the present application, any modification, equivalent change and modification of the above embodiments according to the technical essence of the present application are still within the scope of the technical solution of the present application.
