Problems solved by technology

The existing rotary cylinder usually adopts the working mode of pressing down while rotating. The down-pressing rod is generally installed on the piston rod. The down-pressing stroke of the down-pressing rod is equal to the stroke of the piston rod. A certain space is reserved for the downward pressure and rotation of the rod, which leads to the large volume of the existing rotary cylinder and is not suitable for the use environment of a specific narrow space, so that clamping and avoidance cannot be realized

Embodiment Construction

[0016] In order to make the objectives, technical solutions, and beneficial technical effects of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described in this specification are only for explaining the present invention, not for limiting the present invention.

[0017] See figure 1 and figure 2 The cylinder 100 provided in this embodiment includes a cylinder body 10 and a piston 20, a piston rod 30, a guide member 40, a main shaft assembly 50, and an elastic member 60 installed and housed in the cylinder body 10. The piston 20 is connected to one end of the piston rod 30 and movably installed in the cylinder 10 together with the piston rod 30. The guide 40 is sleeved on the position of the piston rod 30 close to the piston 20 and is slidably connected with the piston rod 30. One end of the main ...

Abstract

The invention provides a cylinder which comprises a cylinder body, a piston, a piston rod, a guide part, a spindle component and an elastic part, wherein the piston is placed in the cylinder body. One end of the piston rod is connected with the piston, the piston drives the other end of the piston rod to move backwards and forwards in the cylinder body, the guide part is close to the piston and sleeved on the piston rod, one end of the piston rod far away from the piston is placed in the spindle component, can axially slide relative to the spindle component and is connected with the spindle component in a rotation retaining manner, the elastic part is sleeved on the piston rod and clamped between the guide part and the spindle component, a penetrated sliding groove is formed in the circumferential wall of one end of the piston rod far away from the piston along the axis direction, the piston rod drives the spindle component to rotatably move around an axis when the spindle component slides relative to the sliding groove, and the piston rod drives the spindle component to move around the axis when the spindle component is fixed relative to the sliding groove. The cylinder is small in size and applicable to narrow and small space, so that effective clamping and avoiding are achieved.

Description

[0001] 【Technical Field】 [0002] The invention relates to a cylinder, in particular to a rotary press cylinder. [0003] 【Background technique】 [0004] In the design of the fixture, a cylinder with a rotating function is usually used to fix the product. The existing rotary cylinder usually adopts the working mode of pressing down while rotating. The lower pressing rod is generally installed on the piston rod. The pressing stroke of the lower pressing rod is equal to the stroke of the piston rod, so that the cylinder of the rotating cylinder needs to be pressed down. A certain space is reserved for the pressing and rotation of the rod, which causes the existing rotating cylinder to be larger in size and not suitable for use in a specific narrow space, so that clamping and avoiding positions cannot be achieved. [0005] In view of this, it is necessary to provide a cylinder that can be operated in a small space and has a small volume. [0006] [Content of the invention] [0007] The obj...
