[0032] See also Figure 1-Figure 5 The industrial oil cylinder with telescopic and pitching stroke provided in the present application comprises an oil cylinder body 10, an oil cylinder main shaft 20, a stroke compound mechanism 30, a main shaft seal 40 and a cylinder body sealing cover 50. The oil cylinder main shaft 20 and the stroke compound mechanism 30 are both sealed and assembled in the oil cylinder body 10 and packaged by the cylinder body sealing cover 50. One end of the oil cylinder main shaft 20 extends out of the oil cylinder body 10, and the other end of the oil cylinder main shaft 20 is connected to the stroke compound mechanism 30. The end of the oil cylinder main shaft 20 extending out of the oil cylinder body 10 is sealed with the oil cylinder body 10 through the main shaft seal 40. The oil cylinder body 10 is provided with an upper oil circuit 110 and a lower oil circuit 120. When the hydraulic oil of the oil cylinder body 10 is injected from the lower oil circuit 120, the stroke compound mechanism 30 can drive the oil cylinder main shaft 20 to perform horizontal movement and tilt movement successively under the action of the oil pressure. When the oil pressure in the lower oil circuit 120 is removed and hydraulic oil is injected into the cylinder body 10 from the upper oil circuit 110, the stroke compound mechanism 30 can drive the cylinder main shaft 20 to perform tilting and horizontal movements successively under the action of the oil pressure. The aforementioned horizontal movement corresponds to the telescopic stroke, and the tilting movement corresponds to the pitching stroke.

[0033] The typical application scenario is: when the hydraulic oil is injected into the cylinder body 10 from the lower oil circuit 120, the cylinder piston rod first extends horizontally, and then tilts to press the workpiece after reaching the work station. When the hydraulic oil is injected into the cylinder body 10 from the upper oil circuit 110, the cylinder piston rod first tilts in the opposite direction to release the workpiece, and then retracts horizontally to return to its original position. When the cylinder main shaft 20 performs horizontal telescopic movement or tilting movement, the seal 40 is used to provide a sealed connection and an elastic deformation connection between the cylinder main shaft 20 and the cylinder body 10.

[0034] The stroke compound mechanism 30 includes a stroke piston 310, a linear stroke navigation component 320, a curved stroke navigation component 330 and a stroke coupling component 340. The cylinder main shaft 20 is provided with a stroke coupling structure 210 and a stroke navigation structure 220, and the stroke coupling structure 210 and the stroke navigation structure 220 are respectively arranged on opposite sides of the cylinder main shaft 20. The linear stroke navigation component 320 and the curved stroke navigation component 330 are both fixedly installed in the stroke piston 310, the stroke coupling component 340 simultaneously connects the stroke coupling structure 210 and the linear stroke navigation component 320, and the curved stroke navigation component 330 is connected to the stroke navigation structure 220; after the stroke piston 310 is subjected to oil pressure, the cylinder main shaft 20 can make a linear motion along the linear stroke navigation component 320 under the cooperation of the linear stroke navigation component 320, the stroke coupling component 340 and the stroke coupling structure 210, and can also make a rotational motion around the stroke coupling component 340 under the cooperation of the curved stroke navigation component 330 and the stroke navigation structure 220.

[0035] The linear travel navigation component 320 is provided with a linear travel navigation inclined surface 3210, and the travel coupling component 340 is provided with a linear travel matching inclined surface 3410 for matching the linear travel navigation inclined surface 3210. The linear travel navigation inclined surface 3210 and the linear travel matching inclined surface 3410 are provided with mutually coupled toothed navigation structures. The travel coupling structure 210 is an arc groove provided on the oil cylinder main shaft 20, and in this embodiment, it is a circular arc groove. The travel coupling component 340 is provided with a travel coupling matching structure 3420 for matching the travel coupling structure 210, and the travel coupling matching structure 3420 is an arc contact portion provided on the travel coupling component 340, and in this embodiment, it is a cylindrical contact portion. The travel coupling component 340 is connected to the linear travel navigation component 320 through the matching between the linear travel navigation inclined surface 3210 and the linear travel matching inclined surface 3410, and at the same time, the travel coupling component 340 is also connected to the oil cylinder main shaft 20 through the matching between the travel coupling structure 210 and the travel coupling matching structure 3420. After the stroke piston 310 and the linear stroke guide component 320 are subjected to oil pressure, a driving force can be applied to the cylinder main shaft 20 through the stroke coupling component 340 .

[0036] The curved travel navigation component 330 is provided with a curved surface navigation part 3310, which is a spherical navigation part in this embodiment. The travel navigation structure 220 is a gradual groove structure provided on the cylinder main shaft 20, and the gradual groove structure has an arc that matches the curved surface navigation part 3310 and the depth of at least part of the groove gradually deepens: the gradual groove in this embodiment includes a curved surface groove section 2210 and a gradual groove section 2220, the structure of the curved surface groove section 2210 matches the curved surface navigation part 3310, and the gradual groove section 2220 has an arc that matches the curved surface navigation part 3310 and the depth of the groove gradually deepens. The curved travel navigation component 330 is connected to the travel navigation structure 220 through the coordination of the curved surface navigation part 3310 and the gradual groove structure. After the travel piston 310 is subjected to oil pressure, it can apply a driving force to the cylinder main shaft 20 through the curved travel navigation component 330 to cause the cylinder main shaft 20 to rotate.

[0037] Principle description:

[0038] 1. Complete the horizontal extension stroke first, and then complete the downward tilt stroke. After the hydraulic oil is injected into the cylinder body from the lower oil circuit 120, the stroke piston 310 is subjected to upward pressure and transmits the pressure to the cylinder main shaft 20 through the stroke coupling component 340. After the cylinder main shaft 20 is subjected to pressure, it drives the stroke coupling component 340 to make a linear motion upward along the straight stroke navigation inclined plane 3210 (this application stipulates: the end of the cylinder main shaft 20 extending out of the cylinder body 10 is the upper part). At the same time, when the cylinder main shaft 20 starts to make an upward linear motion along the straight stroke navigation inclined plane 3210, it will also be subject to the extrusion driving force from the stroke navigation component 330. Under the action of the stroke navigation component 330, the cylinder main shaft 20 begins to make a downward tilted rotational motion around the stroke coupling component 340. After the stroke coupling, it is intuitively manifested as the cylinder main shaft 20 first extending forward horizontally, and then tilting downward.

[0039] 2. Complete the upward tilt stroke first, and then complete the horizontal retraction stroke. After the oil pressure is removed from the lower oil circuit 120, the hydraulic oil is fed into the cylinder body 10 from the upper oil circuit 110. After the cylinder main shaft 20 and the stroke piston 310 are subjected to downward pressure, they drive the stroke coupling component 340 to move linearly downward along the linear stroke navigation inclined surface 3210. At the same time, when the cylinder main shaft 20 begins to move linearly downward along the linear stroke navigation inclined surface 3210, it is also subject to the extrusion driving force from the stroke navigation component 330. Under the action of the stroke navigation component 330, the cylinder main shaft 20 begins to make an upward rotational motion around the stroke coupling component 340. After the stroke coupling, it is intuitively manifested as the cylinder main shaft 20 first rising upward and then retracting horizontally.

[0040] Effect description: From the above description, it can be seen that the industrial cylinder with telescopic and pitching strokes provided in the present application can not only complete the horizontal extension and horizontal retraction strokes, but also complete the downward tilting and upward lifting pitching strokes through the cooperation between the stroke piston 310, the straight stroke navigation component 320, the curved stroke navigation component 330 and the stroke coupling component 340. Compared with the existing technology, it has technical effects such as higher degree of automation and better applicability.

It should be noted that the specific implementation methods disclosed in the specification are only preferred embodiments of the present application, and technical personnel in the field can also develop other embodiments on this basis; any simple deformation and equivalent substitution that does not deviate from the innovative concept of the present application are covered by the present application and fall within the scope of protection of this patent.
