Problems solved by technology

However, compared with a converter without a position detection and adjustment mechanism, the conventional converter has a larger converter body due to the position detection and adjustment mechanism.
Therefore, in conventional converters, it is difficult to reduce their size and weight

Embodiment Construction

[0048] Next, the cylinder in the embodiment of the present invention will be described first, and then the position detection sensor mounted on the cylinder in the embodiment of the present invention will be described.

[0049] The cylinder represented by reference numeral 10 comprises: a substantially cylindrical cylinder 14 having a pair of pressurized fluid inlets / outlets 12a and 12b separated by a predetermined distance; and a rod sleeve 18 fitted in a threaded hole on the other end of the cylinder 14 .

[0050] In the cylinder 14, there are four mounting holes 20a to 20d extending in the axial direction. By tightening unrepresented screws in the threaded portions of the mounting holes 20a to 20d, or by tightening unrepresented bolts in the mounting holes 20a to 20d, the cylinder 10 can be easily mounted on a wall surface or the like. superior.

[0051] Such as image 3As shown, the cylinder 10 also includes: a piston 24, which can move along the cylinder chamber 22 def...

Abstract

A cylinder comprising a piston (24) and a piston rod (26), wherein the piston and The piston rod moves integrally along a cylinder chamber (22), said cylinder comprising: a cylinder barrel (14); a cover element (18), which engages with an end portion of said cylinder barrel (14) to form a cylinder chamber ( 22); and a seal (62), which fits in the junction between the cylinder (14) and the cover element (18); wherein the seal (62) has a ring-shaped edge (64) A pinched compression portion, the annular edge being formed either on the inner circumference (66) of said cylinder (14) or on the outer circumference of said cover element (18). Therefore, liquid can be prevented from entering the cylinder.

Description

technical field [0001] The present invention relates to a cylinder and a position detection sensor, which can prevent liquid from collecting on the outer surface of the cylinder, thereby avoiding environmental sanitation problems. Background technique [0002] Hitherto, hydraulic cylinders have been used as drive devices for moving and positioning workpieces or driving various industrial machines. The hydraulic cylinder is provided with a cylinder and accessories including a converter connected to the cylinder in order to meet various requirements of the user, for example, to reduce the size and realize various functions such as selection setting and the like. The result of this is that the hydraulic cylinder has a complex shape. [0003] However, when the above-mentioned conventional hydraulic cylinder is assembled in a food processing machine or the like, the complicated structure of the cylinder tends to trap the liquid in the irregular Surfaces such as the grooves of c...
