Technical Field

[0001] The utility model relates to the technical field of cylinders, in particular to a cylinder body. Background Art

[0002] A cylinder is a device that converts the energy of compressed air into mechanical energy. It has the characteristics of simple structure, easy installation and easy maintenance. It is widely used in automated production equipment, such as in automobile manufacturing production lines for grasping, handling and assembling parts; in packaging machinery for pushing products and folding packaging materials; and in logistics equipment for sorting and conveying goods.

[0003] The cylinder body is the main component of the cylinder and serves as the basic framework for the entire cylinder. It provides space for the piston, piston rod, and other internal components to move. Much like the walls of a house, the cylinder body defines the cylinder's shape and internal volume and serves as a connection to external equipment and brackets.

[0004] The installation angle and position of the existing cylinder body are often fixed and cannot be adjusted or the adjustment operation is cumbersome, which limits the use of the cylinder. Summary of the Invention

[0009] Furthermore, the adjustable mounting seat is provided with a through hole for the pull rod to slide through.

[0010] Furthermore, the position of the adjustable mounting seat relative to the axial direction of the cylinder barrel is variable and fixable.

[0011] Furthermore, a fixed flat disc is provided on the outside of the adjustable mounting seat, and the fixed flat disc is connected to the rotatable flange via a rotating support and an angle adjustment mechanism.

[0012] Furthermore, the rotation angle adjustment mechanism includes a gear disc three and a spiral gear column two that are meshed and transmitted with each other. The gear disc three is fixedly connected to the fixed flat disc coaxially, and the spiral gear column two is connected to the flat surface of the rotatable flange through a bearing frame.

[0013] Furthermore, bolt connection holes are provided through the upper and lower flat surface of the rotatable flange.

DETAILED DESCRIPTION

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating the basic structure of the present invention only in a schematic manner. Therefore, they only show components relevant to the present invention. While the present invention is described in detail using structural diagrams, these diagrams are merely examples and should not limit the scope of protection of the present invention.

[0025] See also Figures 1 to 4 A cylinder body comprises a cylinder barrel 1 with two through ends, each end of the cylinder barrel 1 is connected to an end cover 2, the two separate end covers are connected by a tie rod 3, the number of the tie rods 3 is ≥4, and an adjustable mounting seat 4 is movably sleeved on the periphery of the cylinder barrel 1. The setting of the adjustable mounting seat 4 enables the installation angle and position of the cylinder to be adjustable.

[0026] On the one hand, in order to realize that the axial position of the adjustable mounting seat 4 relative to the cylinder 1 can be changed and fixed at the desired position, the adjustable mounting seat 4 is provided with a toothed toothed disc 1 4a and a toothed disc 2 4b, and two adjacent pull rods 3 in the pull rod 3 are linearly arranged with racks 3a that mesh with the toothed disc 1 4a and the toothed disc 2 4b, and the toothed disc 1 4a and the toothed disc 2 4b are meshed and connected with the same spiral gear column 1 4c, and the spiral gear column 1 4c is provided between the toothed disc 1 4a and the toothed disc 2 4b, and the rotating shafts of the toothed disc 1 4a, the toothed disc 2 4b and the spiral gear column 1 4c are all connected to the adjustable mounting seat 4 through bearings, and the rotating shaft of the spiral gear column 1 4c is connected to the toothed disc 1 4a and the toothed disc 2 The rotating axes of 4b are perpendicular to each other, and the gear disc 1 4a and gear disc 2 4b rotate synchronously and in opposite directions. The adjustable mounting seat 4 is provided with a through hole 4e for the pull rod 3 to slide through, and the end head of the spiral gear column 1 4c is provided with a hexagonal bolt head. By inserting a tool and screwing the spiral gear column 1 4c, the spirally wound rack on its outside can drive the gear disc 1 4a and gear disc 2 4b to rotate. Due to the meshing action of the gear disc 1 4a and gear disc 2 4b with the rack 3a, the axial position of the adjustable mounting seat 4 relative to the cylinder barrel 1 is adjusted. After adjusting to the desired position, the self-locking effect between the spiral gear column 1 4c and the gear disc 1 4a and gear disc 2 4b fixes the position of the adjustable mounting seat 4 outside the cylinder barrel 1.

[0027] Furthermore, to achieve adjustable cylinder installation angles, the adjustable mounting base 4 is externally connected to a rotatable flange 5, the flat surface of which is penetrated by bolt holes at its upper and lower edges. Specifically, the adjustable mounting base 4 is externally provided with a fixed flat disc 4d, which is connected to the rotatable flange 5 via a rotating support 4f and an angle adjustment mechanism 4g. The rotating support 4f supports relative rotation between the fixed flat disc 4d and the rotatable flange 5 but cannot lock the fixed flat disc 4d in the desired position. The angle adjustment mechanism 4g comprises a meshing gear disc 3 4g-1 and a helical gear column 2 4g-2. The gear disc 3 4g-1 is coaxially fixedly connected to the fixed flat disc 4d, while the helical gear column 2 4g-2 is connected to the flat surface of the rotatable flange 5 via a bearing bracket. The end of the spiral gear column 2 4g-2 is provided with a hexagonal bolt head. By inserting a tool and screwing the spiral gear column 2 4g-2, the gear disc 3 4g-1 can be rotated to adjust the installation angle of the cylinder 1 relative to the rotatable flange 5 and turn the cylinder to the required angle.

[0028] The utility model realizes that the axial position of the adjustable mounting seat 4 relative to the cylinder 1 can be changed and fixed at the required position, and also realizes the installation angle adjustment of the cylinder 1 relative to the rotatable flange 5, so that the cylinder is turned to the required angle, and both adjustments have a self-locking function, which can be fixed at the required setting position, and is easy to use and adjust.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present invention, implementing changes, modifications or additions should all fall within the protection scope of the present invention.
