Housing part for a pneumatic clamping and/or braking device

A clamping and/or braking device for clamping and/or braking an object to be clamped and/or braked, comprising:

• a housing comprising a first housing part and a second housing part, the first housing part comprising:
• a first annular recess for clamping a first annular spring plate between a first contact surface of the first housing part defined by the first recess and a second contact surface of the first housing part defined by the first recess;
• a first clamping element having a first clamping surface which is designed, when the first spring plate is clamped in the first recess between the first contact surface of the first housing part and the second contact surface of the first housing part in such a way that a first end of the first spring plate is supported on the first contact surface of the first housing part, the first spring plate extends from the first contact surface of the first housing part to the second contact surface of the first housing part, and a second end of the first spring plate presses on the second contact surface of the first housing part, to transmit a first clamping and/or braking force to an object to be clamped and/or braked;
• and
• a first latching means of the first housing part and a second latching means of the first housing part;
• and
• the second housing part comprising:
• a second annular recess for clamping a second annular spring plate between a first contact surface of the second housing part defined by the second recess and a second contact surface of the second housing part defined by the second recess;
• a second clamping element having a second clamping surface which is designed, when the second spring plate is clamped in the second recess between the first contact surface of the second housing part and the second contact surface of the second housing part in such a way that a first end of the second spring plate is supported on the first contact surface of the second housing part, the second spring plate extends from the first contact surface of the second housing part to the second contact surface of the second housing part, and a second end of the second spring plate presses on the second contact surface of the second housing part, to transmit a second clamping and/or braking force to the object to be clamped and/or braked;
• and
• a first latching means of the second housing part and a second latching means of the second housing part, wherein the two housing parts are arranged and fastened with respect to one another such that the first and second recesses together form an inner space within the housing;
• and
• a spring arranged in the inner space, comprising the first annular spring plate and the second annular spring plate, wherein the first and second spring plates are arranged within the inner space such that at least one pressure space is formed in the inner space, which pressure space is at least partially delimited by the first and second spring plates, wherein the pressure space is ventilable or ventable and can be acted on by positive pressure of a pressure medium which is suppliable to the housing,
• wherein the first spring plate is clamped in the first recess between the first contact surface of the first housing part and the second contact surface of the first housing part such that a first end of the first spring plate is latched by the first latching means of the first housing part and a second end of the first spring plate is latched by the second latching means of the first housing part;
• and
• wherein the second spring plate is clamped in the second recess between the first contact surface of the second housing part and the second contact surface of the second housing part such that a first end of the second spring plate is latched by the first latching means of the second housing part and a second end of the second spring plate is latched by the second latching means of the second housing part;
• and
• wherein the first and second spring plates are arranged relative to the at least one pressure space such that by ventilating or venting the pressure space or acting on the pressure space with positive pressure, a bending of at least one of the first and second spring plates is changeable and thereby the device changes between an open state, in which the object is spaced apart from the first and second clamping surfaces, and a closed state, in which one or more of the first and second clamping surfaces transmit a clamping and/or braking force to the object.
