Description

Transportable processing unit

The invention relates to a transportable

Machining unit, in particular a table-top circular saw, for machining a workpiece with a tool, comprising a support structure which can be placed on a base and which has a workpiece support plate which can be used for placing the workpiece to be machined, and also a table saw

Drive device for the mechanical drive of the tool.

DE 20 2004 009 123 Ul describes a table-top circular saw with a housing, the circumferentially and underside with in

Essentially closed outer surfaces is provided. The housing carries a worktop with a support surface. A machine frame for holding a motor and a

Saw blade is arranged below the worktop.

An object of the invention is to improve a transportable processing unit of the type mentioned in that even larger workpieces can be placed stable on the workpiece support plate, while maintaining the portability of the processing unit.

The object is achieved by means of the features specified in the characterizing part of claim 1. According to the invention, the workpiece support plate comprises a first plate part and a relative to the first plate part about a vertical axis of rotation pivotally mounted second plate part. The second plate part is pivotable relative to the first

Plate part either positionable in a transport position or in a working position.

Characterized in that the second plate part about a vertical

Is mounted rotation axis, the horizontal support surface of the workpiece support plate can be changed by pivoting the second plate member. The workpiece support plate can be adapted in this way to larger workpieces, so that even larger workpieces can be placed stable on the workpiece support plate. Because the second

Plate part is positioned in a transport position, the portability of the processing unit is maintained. In this context, the position of transport of the second plate part, in which the horizontal cross section of the processing unit is minimal, should be referred to as the transport position.

Advantageous developments of the invention are the subject of the dependent claims.

Preferably, the workpiece support plate is in the

Working position of the second plate member in at least a first spatial direction greater than in the transport position of the second plate member. Expediently, the first spatial direction is a horizontal spatial direction.

Expediently, the first spatial direction is orthogonal to a machining direction predetermined by the tool. In particular, the machining direction is a feed direction in which the workpiece to be machined is pushed onto the tool. In a table saw, in which the tool is a saw blade, corresponds to the Machining direction, for example, the longitudinal direction of the saw blade. According to the described development, the workpiece support plate is enlarged in the working position orthogonal to the machining direction. In the mentioned

Example of a circular table saw can thus be placed stable on the workpiece support plate especially in a parallel section and wider workpieces.

Preferably, the workpiece support plate has a first plate portion and a relative to the first

Plate portion displaceable in a direction of displacement second plate portion. In particular, the second plate portion comprises the first plate part and the second one

Plate part. Appropriately, it is in the

Shifting direction by the machining direction specified by the tool. The described sliding second plate portion facilitates the feeding of a workpiece to the tool. Characterized in that the second plate portion is provided with the pivotable second plate member, its bearing surface can be changed and thus adapted to larger workpieces.

Expediently, the first spatial direction is orthogonal to the displacement direction, so that even wider workpieces can be stably placed on the displaceable second plate section.

According to a preferred embodiment, the workpiece support plate in the transport position of the second

Plate part a horizontal cross section with a substantially rectangular outer contour. In particular, the first plate part and the second plate part lie in the same horizontal plane. Conveniently, the second plate part provides a corner region of the workpiece Platen 4. In particular, the horizontal support surface of the second plate member has a rectangular shape. Accordingly, the horizontal bearing surface of the first plate member may have a shape corresponding to a rectangle at the one corner portion of which a rectangular portion is missing. By way of example, the bearing surface of the first plate part may have an L-shape. Because of that

Workpiece support plate horizontally in the transport position has a substantially rectangular outer contour, a good transportability of the processing unit is achieved, especially if the support structure also has a horizontal cross section with a substantially rectangular outer contour, preferably the rectangular outer contour of the workpiece support plate

corresponds.

Conveniently, the second plate part in the

Working position pivoted by 180 ° relative to the transport position.

According to a preferred embodiment, the first plate part has a first groove and the second plate part has a second groove. In particular, the second groove is arranged in the working position of the second plate part in alignment with the first groove. Preferably, the first groove and the second groove are arranged in the bearing surface of the workpiece support plate. In particular, the first groove and the second groove each extend straight and form a continuously extending straight groove in the working position of the second plate part. In the transport position of the second plate part, the first groove and the second groove preferably run parallel to each other. According to a preferred embodiment, the transportable processing unit comprises a workpiece stop with a sliding block assembly, which is positionable in the working position of the second plate member simultaneously in the first groove and the second, so as to the second plate member in the working position relative to the first plate member

lock. The workpiece stop consequently serves not only as a stop for the workpiece to be machined but also as a locking element for locking the second

Plate part in the working position.

Conveniently, the first plate member has a third groove crossing the first groove. In particular, the third groove is straight. Conveniently, the third groove is arranged orthogonal to the first groove. The first groove can be referred to in this context as a transverse groove and the third groove as a longitudinal groove. Preferably, the

Workpiece stop can be positioned with its slot arrangement either in the first or the third groove. If the workpiece system is positioned in the first groove, it can serve as a rip fence, whereas the workpiece stop in the third groove can serve as a transverse stop. In an advantageous manner, one and the same workpiece stop can optionally serve as a transverse stop or a rip fence.

According to a preferred embodiment, the support structure is box-shaped. Preferably, the second plate member projects in the working position on the outer contour of the horizontal

Cross section of the support structure addition. Furthermore, the second plate part preferably does not protrude beyond the outer contour of the horizontal cross section in the transport position

Support structure out. According to this development, the transportable processing unit has a total box-shaped basic shape when the second

Plate part is located in the transport position. Consequently, the processing unit can be transported and stowed particularly well.

Preferably, the support structure has support structure coupling means suitable for, in a state in which the support structure together with at least one

box-shaped body forms a vertical stack to provide a detachable, vertically tension-resistant coupling with the least one box-shaped body. The transportable processing unit can in particular in the manner of a

System box can be housed in a vertical stack of system boxes. In this context, the described pivotability of the second plate member relative to the first plate member is particularly advantageous because it

allows the editing unit in the

Transport position of the second plate member can meet the predetermined dimensions for a given system, and thus can be accommodated without problems in a stack of system boxes this system.

Control device.

FIG. 1 shows a perspective view of a

transportable processing unit 10. The transportable processing unit 10 extends into one

Vertical direction parallel to that in the figures

drawn z-axis, in a longitudinal direction which is parallel to the drawn in the figures x-axis, and in a transverse direction which is parallel to the drawn in the figures y-axis. The x-axis, y-axis and z-axis are aligned orthogonal to each other.

The transportable processing unit 10 is formed in the figures shown by way of example as a table saw.

Alternatively, the transportable processing unit 1 also be designed as another semi-stationary machine, such as a router, a scroll saw or an edge grinder. As semi-stationary

Machine should in this context, in particular a

Machining unit to be referred to in the

Workpiece machining is placed on a base and which is suitable to be worn by a person during transport.

The transportable processing unit 10 serves the

Processing of a workpiece not shown in the figures with a tool 1. The tool 1 is exemplified in the figures as a saw blade.

The transportable processing unit 10 comprises a support structure 2 which can be placed on a base and which is designed to be box-shaped by way of example. At the box-shaped

Support structure 2 is expediently a substantially cuboid structure in which the

Outer surfaces, preferably all outer surfaces, in

Are essentially closed. By way of example, the support structure 2 comprises a lower part 3 and an upper part 16 which can be placed on the lower part 3. The lower part 3 is designed as a box-shaped example. In the figure 1 is the

transportable processing unit 10 shown in a state in which the upper part 16 of the lower part of the third

is removed. FIG. 5 shows the transportable

Processing unit 10 in a state in which the upper part is placed on the lower part 3.

The portable processing unit 10 includes a

Drive device 5, for example, an electric motor and possibly a corresponding control electronics, for

mechanical drive of the tool 1. Exemplary is the Drive device 5 completely in the lower part. 3

arranged and fixed to the lower part 3 ready for operation, so that the drive means 5 remains in the machining of the workpiece by the drive device driven by the tool 1 in the lower part 3.

The support structure 2 has a workpiece support plate 4 which can be used for placing the workpiece to be processed. In FIG. 1, the workpiece support plate 4 forms the fourth support plate 4

exemplarily the top of the lower part 3.

The workpiece support plate 4 has a first

Plate member 121 and a relative to the first plate member 121 pivotally mounted about a vertical axis of rotation second plate member 122. The second plate member 122 is through

Pivoting relative to the first plate member 121 selectively in a transport position or in a working position

positionable. Figures 1 and 3 show the second

Plate member 122 each in the transport position, while Figures 2 and 4 show the second plate member 122 respectively in the working position.

By way of example, the first plate part 121 and the second plate part 122 do not overlap in the

Transport position still in working position; i.e. the first plate part 121 and the second plate part 122 occupy a same horizontal area neither in the transport position nor in the working position.

By the described pivotability of the second

Plate part 122 has the advantage that the provided by the workpiece support plate 4 support surface can be flexibly adapted, so that in particular larger workpieces stable on the workpiece support plate 4th can be hung up. At the same time, by the

Providing a transport position the

Maintain transportability of the processing unit 10.

As shown in Figures 2 and 4, the workpiece support plate 4 is in the working position of the second

Plate part 122 in at least a first spatial direction - i shown in the longitudinal direction x - increases, so that even larger workpieces can be placed stable on the workpiece support plate 4. The second

Plate part 122 protrudes here over the outer contour of the

horizontal cross section of the support structure 2 addition.

Figures 1 and 3 show the second plate member 122 in de transport position. In the transport position towers

Plate member 122 does not extend beyond the outer contour of the horizontal cross section of the support structure 2, so that the

horizontal cross section of the support structure 2 is minimal. As a result, the transportable processing unit 10 can be transported and stowed particularly well in the transport position of the second plate part 122.

Below are further exemplary details of the

shown embodiment discussed.

As already mentioned above, the support structure 2 is box-shaped. The support structure 2 has four orthogonally oriented peripheral walls. The peripheral walls include a front wall 12, a rear wall 13, and side walls 25 and 26. The front wall 12 and the

Rear wall 13 are parallel to the longitudinal direction x

aligned, and the side walls 25, 26 are aligned parallel to the transverse direction y. The support structure 2 has a box-shaped lower part 3 and an upper part 16 detachably attachable to the lower part 3. Alternatively, the transportable

Machining unit 10 may be formed without upper part 16. In this case, expediently, the lower part 3 represent the entire support structure.

The upper part 16 of the support structure 2 is designed as a hood-shaped cover. In that shown in FIG

State, the upper part 16 covers the workpiece support plate 4. The horizontal cross section of the upper part 16 has substantially the same outer contour as the horizontal cross section of the lower part 3. The upper part 16 is

arranged in alignment with the lower part 3, so that it forms the box-shaped support structure 2 together with the lower part 3.

The workpiece support plate 4 represents the upper side of the box-shaped lower part 3

Saw blade trained tool 1 is partially disposed above the workpiece support plate 4. The tool 1 passes through an opening of the workpiece support plate 4, so that a part of the tool 1 is located above the workpiece support plate 4. Below the workpiece support plate 4, the tool 1 is attached to the drive device 5, so that it can be driven by this. The saw blade is aligned parallel to the transverse direction or parallel to the side walls 25, 26 of the support structure 2.

The top or support surface of the workpiece support plate 4 is provided in the example shown with grooves. Alternatively, the top of the workpiece support plate 4 may be provided without grooves or flat or with a different structuring. The workpiece support plate 4 has the first plate part 121 and the second plate part 122. Both plate parts 121 and 122 lie in the same horizontal plane. The second plate portion 122 has a rectangular horizontal support surface and provides a right rear

The horizontal support surface of the first plate member 121 has the shape of a rectangle, which at a corner region a rectangular recess in the size of the second plate portion 122nd

having. The second plate part 122 is in the transport position in this recess.

The second plate part 122 is rotatably supported by a hinge 133 on the first plate part 121. The hinge 133 is located on the outside of the right side wall 26. Das

Hinge 133 has a vertical axis of rotation which is arranged in the region of adjacent corner edges of the first plate part 121 and the second plate part 122. In

Transverse direction y, the second plate member 122 is located approximately in the rear third of the workpiece support plate 4, so that the hinge in the transverse direction y is approximately in the range of 2/3 of the transverse extent of the workpiece support plate 4. In the longitudinal direction x, the second plate part 122 occupies less than 1/3 of the longitudinal extent of the workpiece support plate. The relative location terms "right", "rear", etc., are to be understood starting from a reference point located in front of the front wall 12; the transportable processing unit 10 is located in

Use position.

In the transport position of the second plate part 122, the workpiece support plate 4 has a substantially

rectangular horizontal support surface on. The horizontal cross section of the workpiece support plate 4 has in the Transport position of the second plate member 122 in the

Essentially rectangular outer contour.

In the following, reference will be made to a first side face 131 of the first plate part 121 and to a second side face 132 of the second plate part 122. In the

Transport position of the second plate member 122, the two side surfaces 131, 132 each sections of

Side wall 26 is that of the workpiece support plate. 4

are associated. In the working position of the second

Plate part 122 is the second side surface 132 on the first side surface 131.

As shown in FIG. 4, the second one is located

Plate member 122 in the working position approximately in the middle of the transverse extension of the workpiece support plate 4. Further, the second plate member 122 is in the longitudinal direction x right of the first plate member 121. In the working position, the second plate member 122 increases the workpiece support plate 4 relative to the transport position in the

Longitudinal x.

The longitudinal direction x, in which the workpiece support plate 4 is increased, is orthogonal to the machining direction y predetermined by the tool 1. In the shown

Example of a table saw as transportable

Machining unit 10 can therefore be placed stable on the workpiece support plate 4, in particular in a parallel section and wider workpieces.

The workpiece support plate 4 has a first

Plate section 47 and one relative to the first

Plate portion 47 in a direction of displacement y

sliding second plate portion 48. The saw blade lies on a transverse, imaginary

Line that divides the workpiece support plate 4 in the longitudinal direction in the two plate sections 47 and 48. The

Saw blade is preferably arranged longitudinally off-center to the workpiece support plate 4, so that the second plate portion 48 is longer than the first plate portion 47. For example, the second plate portion 48 in the longitudinal direction about twice as long as the first

Be plate section 47. Preferably, the first

Plate portion 47 fixed relative to the tool 1, while the second plate portion 48 at least in

Transversely mounted, so that it can be moved relative to the tool 1 in the transverse direction. With the displaceably mounted second plate section 48, a workpiece can be guided or moved relative to the tool 1 during processing. On the basis of an arresting device, not shown, the second plate portion 48 can be fixed relative to the tool 1 and the lower part 3. The fixation can be adjusted for example via a provided on the side wall 26 on the lower part 3 knob 49. The second plate portion 48 can be fixed in particular in a position in which it is arranged in alignment with the lower part 3 and the upper part 16.

The second plate portion 48 includes the first plate part

121 and the second plate portion 122. Characterized in that the second plate portion with the pivotable second plate portion

122 is equipped, its bearing surface can be changed and thus adapted to larger workpieces.

FIG. 3 shows the transportable processing unit 10 in a state in which the second plate part 122 is in the transport position. In this state, both the first groove 124 and the second groove 125 open at the

Side wall 26 off. With respect to the transverse direction y, the first groove 124 is centered in the workpiece support plate 4

arranged. The first groove 124 extends in the longitudinal direction x over more than half the length of the workpiece support plate 4. The second groove 125 is arranged in the transverse direction y in a central region of the second plate member 122. In the longitudinal direction x, the second groove 125 extends over the entire length of the second plate part 122.

FIG. 4 shows the transportable processing unit 10 in a state in which the second plate part 122 is in the working position. In this state, the second groove 125 is arranged in alignment with the first groove 124; i.e. the second groove 125 continues the first groove 124 in the longitudinal direction x.

The first plate part 121 further has a third groove 127 which crosses the first groove 124. The third groove 127

runs parallel to the y-axis. The third groove 127 is disposed approximately centrally in the second plate portion 48 with respect to the longitudinal direction x. The third groove 127 runs as an example over the entire transverse extent of the workpiece support plate. 4
