Abstract: Locking device for latching an inner element, preferably a measuring piston, in a dough chamber (20b) of a dough chamber support (10) of a dough divider, comprises a locking pin assembly having an engaging pin movable to and fro between a locked position and an unlocked position. In the locked position, the engaging pin extends at least partially into the dough chamber and is engaged in an adopter of the inner member. In the unlocked position, the engagement pin does not extend into the dough chamber and is not engaged in the adopter of the inner member. Locking device for latching an inner element, preferably a measuring piston, shut-off piston or a sleeve reducing the dough chamber volumes, in a dough chamber (20b) of a dough chamber support (10) of a dough divider, comprises a locking pin assembly having an engaging pin movable to and fro between a locked position and an unlocked position. In the locked position, the engaging pin extends at least partially into the dough chamber and is engaged in an adopter of the inner member. In the unlocked position, the engagement pin does not extend into the dough chamber and is not engaged in the adopter of the inner member. The locking pin assembly is fixed by a bayonet lock in the locked and/or unlocked position. Independent claims are also included for: (1) the dough chamber support for a dough divider, comprising the dough chamber and the inner element and the locking device, which is its housing or housing end, preferably by means of a screw connection and is connected to a wall of the dough chamber or dough chamber support and/or where in the wall, a screw hole is provided for the screwing the fixing portion and preferably also two receiving openings are provided for two positioning pins for pre-positioning and for absorbing torque when tightening the locking device, where the receiving openings are preferably offset by 180[deg] to each other; and (2) assembling the locking device at the dough chamber support (10) with at least one or any combination of the following assembly steps: (a) in a first assembly step, the housing of the locking device is pre-positioned by means of the two positioning pins in the recesses at one end and the receiving openings at the other end to the wall or the wall portion on the dough chamber support, (b) in a second assembly step, the bottom housing closure in the housing casing is introduced, and its attachment section is screwed with its external thread into the internal thread of the threaded hole on the dough chamber support (10) until the base portion comes to rest at the annular projection of the housing, and substantially seals together with the central portion of the opening in the annular projection, where the positioning pins are tightened and absorbs torques, (c) in a third assembly step, the locking pin assembly is inserted into the housing, where its intermediate portion and the engaging pin are introduced into the passageway of the lower housing seal, (d) in a fourth assembly step, the actuator is mounted on a locking bolt assembly (36c), in which a first bayonet joint head is guided through a driving zone of a bayonet slot on a first side of the casing and the two spacers with its outer threads are screwed as long as the internal thread of the passage until the first bayonet coupling head again protrudes to the other side of the casing through the other bayonet slot and the second bayonet head still at the first side of the housing cover protrudes from the bayonet slot and the central narrowing is located in the region of the threaded hole, (e) in a fifth assembly step, in the threaded hole, a set screw for fixing the actuator unit in the region of the taper is screwed, thus the actuator is now fixedly connected to the locking pin assembly during engaging and moving of the bayonet heads in the associated bayonet slots, and during movement within the longitudinal slot portion axially to the longitudinal axis fitted or disassembled to the locking direction and during movement within the cross slot section in the circumferential or rotational direction around the longitudinal axis, (f) in a sixth assembly step, the spring arrangements, preferably the disc springs, are disposed over the upper portion and are then supported on the central portion, (g) in a seventh assembly step, the housing cover with its external thread is screwed into the internal thread of the casing, where the housing cover of the spring arrangement presses against the central portion and compresses and thus the spring arrangement biases to generate a biasing force on the locking pin assembly in the locking direction, (h) where preferably for locking the engaging pin, the bayonet heads from the rest positions, in which they rest on the bearing surfaces of the transverse groove sections, are moved in the cross-slot portions in the direction of the longitudinal slot portions and then is pressed from the spring arrangement by the biasing force downwards into the longitudinal slot portions into the insertion part, and (i) where preferably for unlocking the engagement bolt, the bayonet heads are moved against the biasing force of the spring arrangement into the longitudinal slot portions and are then moved laterally in the transverse slot portions to the rest positions in which they rest on the bearing surfaces of the transverse groove sections.
