Optionally, the rotation module 917 can rotate around an axial direction by an external force.

Alternatively, the rotation direction is a circumferential direction around the axial direction, i.e., a rotation direction around the axial direction. This application the first end of rotation module 917 and the first end of lifting module 913 block in the rotation direction, mean that rotation module 917 can receive lifting module 913's resistance when rotating around the axial, when the rotation moment of torsion that rotates module 917 is greater than lifting module 913's resistance, rotation module 917 can drive lifting module 913 and rotate around the axial in step.

In the cylinder assembly 911 provided by the embodiment of the present application, by arranging the lifting module 913 and the rotating module 917 in the cylinder 915 along the axial direction, and arranging the rotating module 917 to engage with the lifting module 913 in the rotating direction, the lifting module 913 can lift relative to the cylinder 915 under the external force, so as to achieve the lifting driving of the cylinder assembly 911 in the axial direction, and the rotating module 917 can rotate relative to the cylinder 915 under the external force, because the rotating module 917 engages with the lifting module 917, the rotating module 917 can rotate while driving the lifting module 913 to rotate along with the rotating module 917, thereby achieving the rotation driving function of the cylinder assembly 911 around the axial direction, in summary, the cylinder assembly 911 provided by the present application improves the structure, and achieves the telescopic motion and the rotation around the axial direction of the cylinder assembly 911 while the structure is relatively simple, the occupied space is small, the cylinder assembly 911 has more movement forms, and the functions of the cylinder assembly 911 are increased.

It can be understood that the cylinder inner cavity 924 provides a receiving space for the first end of the lifting module 913 and the first end of the rotating module 917, so that the inner space of the cylinder inner cavity 924 is relatively large, and the first through hole 923 and the second through hole 925 respectively provide through holes extending out of the cylinder 915 for the lifting module 913 and the rotating module 917. In this embodiment, the inner diameter of the first through hole 923 is smaller than the inner diameter of the cylinder inner cavity 924, and the inner diameter of the second through hole 925 is equal to or larger than the inner diameter of the cylinder inner cavity 924, so that the lifting module 913 is installed in the cylinder inner cavity 924 through the second through hole 925.

Referring to fig. 3 and 4, the lifting module 913 includes a cylinder rod 927. One end of the cylinder rod 927 is disposed in the cylinder inner chamber 924. The other end of the cylinder rod 927 extends out of the cylinder body 915 through the first through hole 923, and is connected to a workpiece. In the present application, the term "connected" may refer to a direct contact connection between workpieces or an indirect connection between workpieces through an intermediate workpiece.

Optionally, the cylinder rod 927 may be made of, but not limited to, plain carbon steel, hard chrome plated carbon steel, stainless steel, etc. to provide cylinder rod 927 with improved stiffness, corrosion resistance, and wear resistance.

Further, referring to fig. 3 and 4, the cylinder assembly 911 further includes a first sealing member 931. The first sealing member 931 seals between the inner wall of the first through hole 923 and the outer circumferential surface of the cylinder rod 927.

Optionally, the first sealing component 931 is a sealing ring, which may also be referred to as a sealing plug. The material of the first sealing member 931 includes, but is not limited to, silicone rubber, nitrile rubber, neoprene rubber, ethylene propylene rubber, etc.

Since the cylinder rod 927 is capable of moving or rotating axially relative to the first seal 931, the first seal 931 is a dynamic seal between the cylinder 915 and the cylinder rod 927. The connection between the first sealing member 931 and the cylinder 915 includes, but is not limited to, integral molding, riveting, screwing, and the like.

Alternatively, the cylinder rod 927 may be made of, but not limited to, aluminum alloy, carbon steel, stainless steel, etc.

Referring to fig. 3 and 4, the rotation module 917 includes a rotation rod 933. One end of the rotating rod 933 is arranged in the cylinder inner cavity 924. The other end of the rotating rod 933 extends out of the cylinder 915 through the second through hole 925.

Further, referring to fig. 3 and 4, the rotation module 917 further includes a rotation sheet 935. The rotation piece 935 is provided outside the cylinder 915 and is connected to the rotation rod 933. The extending direction of the rotating piece 935 intersects or is perpendicular to the axial direction of the rotating rod 933. The rotating piece 935 is configured to swing to drive the rotating rod 933 to rotate. Optionally, the rotating sheet 935 may rotate around under the action of a motor, an air cylinder, or the like, and the rotating sheet 935 drives the rotating rod 933 to rotate in the rotating process.

The angle at which the rotating rod 933 can be rotated is not particularly limited in the present application.

Optionally, the rotating rod 933 is made of materials including, but not limited to, common carbon steel, carbon steel with a hard chromium plated surface, stainless steel, and the like, so that the rotating rod 933 has good rigidity, corrosion resistance, and wear resistance.

Referring to fig. 3 and 4, the cylinder assembly 911 further includes a second seal 937. Alternatively, the second sealing member 937 is sealed between the inner wall of the second through hole 925 and the outer circumferential surface of the rotating lever 933.

Optionally, the second sealing member 937 is a sealing ring, which may also be referred to as a sealing plug. The material of the second sealing member 937 includes, but is not limited to, silicone rubber, nitrile rubber, neoprene rubber, ethylene propylene rubber, etc.

Since the rotating rod 933 is rotatable relative to the second seal 937, the second seal 937 provides a dynamic seal between the cylinder 915 and the cylinder rod 927. The connection between the second sealing member 937 and the cylinder 915 includes, but is not limited to, integral molding, riveting, screwing, and the like. Alternatively, the outer circumferential surface of the rotating rod 933, which is in contact with the second seal 937, is a cylindrical surface so that the rotating rod 933 can rotate relative to the second seal 937.

Still optionally, the second sealing member 937 includes a sealing bearing and a sealing ring sleeved on the periphery of the sealing bearing, wherein the sealing bearing and the rotating rod 933 are integrally formed or hermetically enclosed on the periphery of the rotating rod 933, and the rotating rod 933 can rotate relative to the sealing bearing. Wherein the sealing bearing and the sealing ring realize the sealing connection between the second through hole 925 and the rotating rod 933.

One end of the rotation lever 933 is engaged with one end of the cylinder rod 927 in the rotation direction. Specifically, one end of the rotation lever 933 and one end of the cylinder lever 927 may be directly engaged in the rotation direction or engaged in the rotation direction via an intermediate coupling member. When the rotating rod 933 rotates under the action of external force, the rotating rod 933 drives the cylinder rod 927 to rotate, and the cylinder rod 927 drives the component to be driven to rotate.

One end of the rotating rod 933 and one end of the cylinder rod 927 are relatively movable in the axial direction, in other words, the rotating rod 933 can be fixed in the axial direction with respect to the cylinder 915 when the cylinder rod 927 is lifted and lowered in the axial direction with respect to the cylinder 915.

The driving manner of the cylinder rod 927 in the axial direction of the cylinder body 915 described in the present application includes, but is not limited to, the following driving manner.

Optionally, referring to fig. 3 and 4, the lifting module 913 further includes a piston 939. The piston 939 is disposed in the cylinder inner chamber 924. One end of the piston 939 is sleeved on the periphery of the cylinder rod 927 or embedded in the cylinder rod 927. The piston 939 is fixedly connected with the cylinder rod 927 into a whole. The outer peripheral surface of the other end of the piston 939 is slidably connected to the inner wall of the cylinder inner chamber 924. The outer peripheral surface of the piston 939 sealingly engages the inner wall of the cylinder chamber 924. When the piston 939 slides along the inner wall of the cylinder inner cavity 924 under the action of external force, the piston 939 drives the cylinder rod 927 to move along the axial direction of the cylinder inner cavity 924, and the cylinder rod 927 performs lifting motion in the cylinder 915 and drives a workpiece to perform lifting motion.

Optionally, referring to fig. 3 and 4, when one end of the piston 939 is embedded in the cylinder rod 927, the piston 939 may be sleeved on the periphery of the rotating rod 933. In other words, the rotating rod 933, the piston 939, and the cylinder rod 927 are sequentially nested. Wherein piston 939 is interference fit with cylinder rod 927 such that piston 939 and cylinder rod 927 move together in the axial direction. The piston 939 is slidably connected to the rotating rod 933 in the axial direction. The piston 939 is rotatable together with the rotation rod 933 in the rotation direction.

It is understood that, in the axial direction, the center axis of the cylinder rod 927 is collinear with the center axis of the rotating rod 933. The cylinder inner chamber 924 has oppositely disposed top and bottom walls in the axial direction. The piston 939 can move back and forth between the top wall and the bottom wall under the action of external force, so that the piston 939 drives the cylinder 915 to move axially relative to the rotating rod 933.

The present application contemplates the piston 939 moving back and forth within the cylinder interior 924 including, but not limited to, the following embodiments.

Optionally, referring to fig. 3 and 4, a third through hole 926 and a fourth through hole 928 are further disposed on the peripheral sidewall of the cylinder 915. The third through hole 926 and the fourth through hole 928 both penetrate through the peripheral sidewall of the cylinder 915 and communicate with the cylinder inner chamber 924. The third through hole 926 and the fourth through hole 928 are respectively located on opposite sides of the piston 939 in the axial direction of the cylinder inner chamber 924.

Further, the cylinder assembly 911 further includes an air pressure adjustment module (not shown). The air pressure adjusting module comprises a first air pipe and a second air pipe. Wherein, the first air pipe is communicated with the third through hole 926, and the second air pipe is communicated with the fourth through hole 928. The air pressure adjusting module is used for supplying air to the third through hole 926 or the fourth through hole 928, so that the piston 939 moves along the axial direction of the cylinder inner cavity 924.

The third through hole 926 is proximate the top wall of the cylinder inner chamber 924 and the fourth through hole 928 is proximate the bottom wall of the cylinder inner chamber 924. A first chamber is formed between the piston 939 and the top wall and a second chamber is formed between the piston 939 and the bottom wall. When the air pressure adjusting module supplies air to the third through hole 926, the air pressure of the first chamber is greater than the air pressure of the second chamber, so that the piston 939 moves toward the bottom wall, the piston 939 drives the cylinder rod 927 to be away from the rotating rod 933, but the cylinder rod 927 cannot be separated from the rotating rod 933. When the air pressure adjusting module supplies air to the fourth through hole 928, the air pressure of the second chamber is greater than that of the first chamber, so that the piston 939 moves towards the top wall, and the piston 939 drives the cylinder rod 927 to be close to the rotating rod 933. Thus, the cylinder rod 927 drives the workpiece to lift.

Of course, in other embodiments, the air pressure adjustment module draws air into the fourth through hole 928 to move the piston 939 toward the bottom wall, and the piston 939 drives the cylinder rod 927 away from the rotating rod 933. The air pressure adjustment module draws air into the third through hole 926 such that the piston 939 moves towards the top wall, and the piston 939 drives the cylinder rod 927 to approach the rotating rod 933.

Referring to fig. 3 and 4, the lifting module 913 further includes a lifting clip 929. The lifting clamp 929 is disposed outside the cylinder 915 and connected to the cylinder rod 927. The lifting jaw 929 extends in a direction perpendicular to or intersecting the direction in which the cylinder rod 927 extends. The lifting jaw 929 is adapted to rotate with the rotation of the cylinder rod 927 and cooperate with a clamp plate to clamp or release a workpiece upon the axial movement of the cylinder rod 927. Optionally, the lifting clips 929 are disposed opposite the clamping plate. The clamp plate is arranged between the lifting clamp 929 and the cylinder 915. If the workpiece is positioned between the lift clamp 929 and the clamp plate. When the lifting jaw 929 approaches the rotating lever 933 along with the cylinder lever 927, the distance between the lifting jaw 929 and the clamp plate is reduced to clamp the workpiece. When the lift jaw 929 moves away from the rotating lever 933 along with the cylinder lever 927, the distance between the lift jaw 929 and the clamp plate increases to release the workpiece.

Of course, in other embodiments, the clamp plate can also be disposed on the side of the lift clip 929 facing away from the cylinder 915. The clamp can be a fixed clamp or a lifting clamp 929.

The present invention is not particularly limited to the structure in which the pivot rod 933 is engaged with the cylinder rod 927, and includes, but is not limited to, the following embodiments.

In a first possible embodiment, referring to fig. 3 and 4, the rotating rod 933 is engaged with the cylinder rod 927 by a piston 939. The piston 939 is sleeved on the periphery of the rotating rod 933. The piston 939 and the rotating rod 933 move relatively in the axial direction. The piston 939 engages with the rotating lever 933 in the rotating direction. Rotating rod 933 rotates to drive piston 939 to rotate. The piston 939 is in interference fit with the cylinder rod 927, and the piston 939 drives the cylinder rod 927 to move in the rotating direction. In other words, the piston 939 not only drives the cylinder rod 927 to lift in the axial direction, but also drives the lifting clamping piece 929 to clamp or release the workpiece; the piston 939 also rotates in a rotational direction about the cylinder shaft 927, which in turn rotates the lift clamp 929.

Optionally, referring to fig. 2, at least one corner 941 is disposed on an outer circumferential surface of the rotating rod 933. The piston 939 is provided with at least one recessed portion 943. The recessed portion 943 is engaged with the ridge portion 941 to engage the piston 939 with the rotating lever 933 in the rotating direction.

In a second possible embodiment, referring to fig. 5 and 6, a portion of the piston 939 is sleeved on the outer periphery of the rotating rod 933. A portion of the piston 939 is sleeved around the cylinder rod 927. The pivot rod 933 is directly engaged with the cylinder rod 927. The cylinder rod 927 can be distant from or close to the rotating rod 933 in the axial direction. The cylinder rod 927 moves synchronously with the rotating rod 933 in the rotating direction.

Specifically, referring to fig. 7 and 8, fig. 7 is a cross-sectional view of the cylinder rod 927 along the X-Y plane. The outer circumferential surface of the rotating rod 933 is provided with at least one corner 941. The cylinder rod 927 is provided with at least one recessed portion 943.

The first end 9271 is located within the cylinder interior 924 and the second end 9272 is located outside of the cylinder 915. The outer peripheral surface of the cylinder rod 927 is connected between the first end surface 9271 and the second end surface 9272. At least one recessed portion 943 is proximate the first end surface 9271.

Referring to fig. 6, the rotating rod 933 has a third end surface 9331 and a fourth end surface 9332 opposite to each other, the third end surface 9331 and the fourth end surface 9332 are opposite to each other in the axial direction, the third end surface 9331 is located in the cylinder inner cavity 924, and the fourth end surface 9332 is located outside the cylinder 915. At least one corner 941 is disposed on the third end surface 9331.

The inner wall of the first groove 9273 includes a non-cylindrical reentrant portion 943, the shape of the reentrant portion 943 being complementary to the shape of the corner portion 941. Due to the presence of the recessed portions 943 and the chamfered portions 941, the pivot rod 933 cannot pivot relative to the cylinder rod 927, and therefore the pivot rod 933 pivots the cylinder rod 927 together. Optionally, the third end surface 9331 of the rotating rod 933 and the bottom surface of the first groove 9273 may be attached to each other or disposed at an interval, which is not limited in this application. In this embodiment, the cylinder rod 927 is movable relative to the rotation rod 933 in the axial direction. In other embodiments, the cylinder rod 927 moves in the axial direction together with the rotation rod 933.
