Description

Title of the invention: Functional base for automated manufacturing machine

[0001] The invention relates to a fixing assembly, a machine support frame as well as to a functional base for an automated manufacturing machine comprising such a fixing assembly and such a machine support frame.

[0002] A functional base is known comprising a machine support frame capable of carrying an automated manufacturing machine, in particular a screwing machine, a fluid depositing machine, a marking machine, a crimping machine, a part picking and depositing machine, a cleaning machine, a heat treatment machine, a surface preparation machine or a welding machine, the machine support frame comprising a frame capable of being fixed to the floor.

[0003] Such a functional base is stable but has the disadvantage of being difficult to move. Changing the position of the functional base on a production site is therefore long and costly. Indeed, each change in the position of the functional base requires a new fixing on the ground and a new leveling, that is to say an adjustment of the horizontality.

[0004] The invention aims to eliminate all or part of these drawbacks.

[0005] The invention relates to a fixing assembly capable of being fixed to a floor, the fixing assembly comprising: - a fixing support comprising an upper fixing zone, - a third attachment device fixed to the upper attachment zone, the third attachment device being able to be secured to a fourth attachment device fixed to a lower attachment zone of a machine support frame separate from the attachment support, the machine support frame being able to carry an automated manufacturing machine, in particular a screwing machine, a fluid depositing machine, a marking machine, a crimping machine, a part picking and depositing machine, a cleaning machine, a heat treatment machine, a surface preparation machine or a welding machine.

[0006] Such a fixing support makes it possible to improve the flexibility of a production site. Indeed, depending on the need, it is possible, thanks to such a fixing support, to precisely position a machine support frame carrying an automated manufacturing machine. It is also possible to change the frame and therefore the machine without having to readjust the position of the frame. Indeed, the position of the different machine support frames that can be fixed to the fixing support is given by the support of fixing whose position has been adjusted once when it is fixed to the ground and which does not need to be adjusted each time the machine support frame is changed.

[0007] According to an additional characteristic of the invention, the fixing assembly comprises a leveling assembly.

[0008] Such a leveling assembly allows the initial adjustment of the position of the fixing bracket. This initial adjustment allows a change of machine support frame.

[0009] According to an additional characteristic of the invention, the leveling assembly comprises at least three feet, at least two of which are adjustable in height.

[0010] According to an additional characteristic of the invention, the upper fixing zone (has a first height, the first height being measured between a lower surface of the leveling assembly and an upper surface of the third attachment device, the first height being between 5 cm and 25 cm, the lower surface of the leveling assembly being able to be placed on the ground.

[0011] Such a first reduced height allows the use of taller machine support frames in which the interior space is increased. This increased interior space makes it possible to house a portion of the automated manufacturing machine and / or an electrical control system.

[0012] According to an additional characteristic of the invention, the fixing support is a fixing frame.

[0013] The invention also relates to a machine support frame capable of carrying an automated manufacturing machine, in particular a screwing machine, a fluid depositing machine, a marking machine, a crimping machine, a part picking and depositing machine, a cleaning machine, a heat treatment machine, a surface preparation machine or a welding machine, the machine support frame comprising: - a frame, in particular a metal frame, in particular a mechanically welded metal frame, the frame having a lower fixing zone, - a fourth attachment device fixed to the lower attachment zone, the fourth attachment device being capable of being secured to a third attachment device of a fixing assembly fixed to a floor and separate from the machine support frame.

[0014] According to an additional characteristic of the invention, the machine support frame comprises at least one lifting cavity capable of receiving a fork of a pallet truck or a fork of a forklift.

[0015] According to an additional characteristic of the invention, the machine support frame comprises a first movement assembly, in particular a set of at least three casters of which at least one of the three casters is a swivel caster, the first movement assembly being fixed to the lower fixing zone.

[0016] The invention also relates to a functional base comprising: - a fixing assembly as described above, - a machine support frame as described above, the machine support frame being separate from the machine support frame, the third attachment device being secured to the fourth attachment device.

[0017] According to an additional characteristic of the invention, one of the third attachment device and the fourth attachment device comprises at least one second male attachment element and the other of the third attachment device and the fourth attachment device comprises a second female attachment element, the at least one second male attachment element being inserted into the at least one second female attachment element.
