Description

Oscillating saw and circular table saw.

The present invention relates to a saw oscillating and a circular table saw with the characteristics of the preamble of claim 1.

It is known from the state of the art, that constitutes the starting point of the present invention, a saw oscillating and circular table saw (DE 29 08 211 A1), in which a saw aggregate is installed in a fixing bracket rotating shape around a transverse axis. Accommodation rotating aggregate saw serves for saw function Oscillating saw oscillating and circular table saw. Further, a saw table is provided, which is arranged in such a way that the saw blade extends upward through the saw table. The table of the saw serves in this case as support surface for a work piece in the case of use of the oscillating saw and circular table saw as circular table saw. The table of the saw is adjustable in the height, so that the depth of cut can be adjusted. The saw table is housed in two cranks in the form of parallelogram, through which the regulation of the height. After a height adjustment, it is carried out by means of a clamping lever, which is arranged in one of the parallelogram-shaped cranks, a fixation in the position correspondent. In this device it is an inconvenience that the Table saw housing is not stable enough. In addition, the groove for the saw blade on the saw table must be made relatively long in order to be able to perform height adjustment. This implies the danger that an object falls into the groove during the saw process and this lead to an accident.

The invention is based on the problem of optimizing the oscillating saw and circular table saw known, explained at the beginning, in relation to the regulatory capacity of the height of the saw table.

The problem mentioned above is solved in an oscillating saw and circular table saw with the features of the preamble of claim 1 through the characteristics of the characterization part of the claim 1. Advantageous developments of the invention are Subject of the dependent claims.

The basic idea of the present invention lies in that the table saw is not already housed in two points or axes opposite, but at least three points apart from each other. This increases the stability of the saw table, since the table of saw is best supported by a third bearing point. To the at the same time the danger of slipping the table of the saw during sawing operation. The accommodation is made in this case so that the table of the saw is can be adjusted in height with easy gear and without staggering

Especially preferred is a configuration, in which in each of the bearing points a support element affects the table of the saw, serving in a preferred way one of the support elements - adjustment element - for the ability to regulate height. Therefore, the table of the Saw can be handled in a simple way.

In addition, a configuration of the oscillating saw and circular table saw, in which only one of the support elements is fixed stationary in the saw table and you can adjust the position of the others support elements on the saw table. This guarantees a especially easy way to compensate for manufacturing tolerances between the saw table and the supporting elements

A configuration is also preferred, in which a saw activation handle, which is arranged in the fixing support of the saw aggregate, configure a guide element for one of the support elements. This way, the third support element of the saw table can be  have a simple way, without requiring a additional fixing bracket.

In another preferred embodiment of the oscillating saw and circular table saw, one of the elements of Support present a position element. Position element is arranged and performed in this case in such a way that config a stop, which guarantees, during the movement of the table of the saw at least in one position, that the plane of the table of the saw and the plane of the saw blade are cut at an angle of 90º. In this way, at least in this position a readjustment of support elements.

The invention will be explained in detail below. with the help of the drawing with reference to an embodiment favorite. In the course of these explanations, they are explained to same time other configurations and developments and others characteristics, properties, aspects and advantages of the invention. In the drawing:

Figure 1 shows an oscillating saw and saw circular table with a support 1, which forms a surface of Workpiece support 2 for a workpiece when use the oscillating saw and circular table saw as a saw oscillating A mounting bracket 3 is mounted on the support 1, in  the one that is installed again above bracket 1 an aggregate 5 saw rotating around a transverse axis 4. The saw aggregate 5 features a drive motor (not sample) and a saw blade 6. On the fixing bracket 3 is also installed a table of the saw 7.

In the present case, the table of the saw 7 is installed in the aggregate of saw 5, which is installed, for its part, on the fixing bracket 3. The saw table 7 forms a support surface of workpiece 8 for a piece of work in the case of use of the oscillating saw and saw circular table as circular table saw. For cleaning and maintenance of the oscillating saw and circular table saw, it you can disassemble the table from the saw 7.

The saw 5 aggregate is rotating around of the transverse axis 4 from a position with the saw blade 6 raised to a position with the saw blade 6 lowered (figure 1) and vice versa. This rotating movement represents in this case the rotational movement necessary for the oscillation of a piece of work. However, they are not described in detail below. oscillating saw function or configuration Corresponding oscillating saw and circular saw table, since they are already known to a sufficient extent from of the state of the art.

The saw 5 aggregate can be fixed in the position with the saw blade 6 lowered, here, indeed, by middle of a hook 9. In this position, the oscillating saw and Circular table saw serves as a circular table saw. Table of the saw 7 provided for this mode of operation is arranged in a height-adjustable way above the engine drive. The table of the saw 7 has a groove 10, a through which a section of the saw blade 6 extends at least during operation as a circular table saw. For protection against injury, the saw blade 6 is protected with a 11 'chip bell that is arranged so  swivel on the top side of the saw table 7 in a wedge of interstitium 11. The table of the saw 7 itself is hosted in at least three, here and preferably exactly in three points distanced from each other on its lower side.

In the present case, in each of the points of bearing strikes a support element 12, 13, 14 on the table of the saw 7. The height adjustment capacity is carried out in this case by means of at least one, here and in a preferred way exactly through one of the support elements 12-14, which is designated below as an element of adjustment 12. This means that for the adjustment of the height of the saw table 7 only this element of setting 12.

One of the support elements 12-14, here the setting element 12, is fixed stationary arrangement on the saw table 7 (figures 2, 3). The position of the other support elements 13, 14 can be regulate on the table of the saw 7. By means of this capacity of adjustment manufacturing tolerances can be compensated produced.

For adjusting the position of the element of respective support 13, 14 is provided in each case an element intermediate 15 with an elongated hole 16 between the saw table 7 and the support element 13; 14. Here and in a preferred way, the intermediate element 15 is installed by means of a screw 17, extending through the elongated hole 16, on the table of the saw 7. The intermediate element 15 and, therefore, also the respective support element 13, 14, can be moved along of the elongated hole 16 and is rotatable around the screw 17, as long as it does not squeeze intermediate element 15. Of This way you can adjust the position of the supporting elements 13, 14.

Here and in a preferred way, each element of support 12-14 is guided in a guide element 18, 19, 20, to achieve during height adjustment, to be possible, a parallel displacement of the saw table 7 (figure 4). Enter the guide element 18-20 respective and the respective support element 12-14 sufficient play is present so that a tilt is avoided side of the respective support element 12-14 in the respective guide element 18-20. The game is dimensioned in this case in a preferred manner so that a deviation from the parallel arrangement is a maximum of some degrees.

Also, here and in a preferred way in each guide element 18-20 an element is arranged lock 21, 22, 23. The lock item 21-23 in this case it presents two positions, namely a position of lock, in which the support element 12-14 is fixed, and a release position, in which the element of 12-14 support is adjustable. Blocking element 21-23 can be moved between these two positions. The locking elements 22, 23 for the supporting elements 13, 14 they are made here as fastening screws (figures 4, 5). We must also take into account that here for a guide element it is understood, in general, also an arrangement of several elements guide and a locking element can be arranged in a way corresponding also in the area of such an arrangement (see figure 6).

Here and in a preferred way, a handle of activation 24, arranged in the fixing bracket 3 or in the aggregate of saw 5, oscillating saw and circular saw table configures one of the guide elements 18-20, namely guide element 20, for one of the supporting elements 12-14, namely the element of support 14. The activation handle 24 as such is present, in principle, in an oscillating saw and circular table saw, of so it is especially convenient to configure it as an element of guide 20 for the support element 14. In this way a third support element 14 without other structures in a way simple. The guide elements 18, 19 of the other two elements of support 12, 13 are arranged in the fixing bracket 3 or in the aggregate of saw 5, which is arranged in the support of fixing 3.

The adjustment element 12 presents here and of a preferred way a rack section 25 (figure 4), with the which meshes a cogwheel 26 that is arranged in the support of fixation 3 or in the aggregate of saw 5 (figure 7). The Cogwheel 26 serves to activate the regulation of the table height and saw 7. Cogwheel 26 is mounted on a tree 27, the tree 27 being arranged such that the table of the saw 7 can be adjusted in height by means of tree rotation 27.

The shaft 27 can be fixed in position. He shaft 27 and cogwheel 26 thus also form the locking element 21 for the adjustment element 12. For this purpose, the tree 27 has a threaded section 28, on which it is mounted a fastener 29 with a corresponding internal thread (figure 7). The fastener 29 is movable between a position clamping, in which the shaft 27 is fixed, and a position of release, in which the tree 27 is rotatable. The element of clamp 29 moves to fix the shaft 27 towards a stop 30 which is arranged in the fixing bracket 3 or in the saw aggregate 5. From the opposite side then press the cogwheel 26 or, as here, a clamping disc 31, which is disposed between the sprocket 26 and the rear side of the stop 30, press against the rear side of the stop 30, so that the tree 27 is interlocked and therefore fixed by means of the wheel toothed 26 and the clamping element 29.

The shaft 27 and the cogwheel 26 are manufactured in a preferred way in one piece and are made as a rotating part, so that there is a connection optimum between shaft 27 and cogwheel 26.

The supporting elements 12-14 They are made as bars, especially metal bars.

In one of the support elements 12-14, here and in a preferred way in the adjustment element 12, an element of position 32 in such a way that it forms a stop 33, which guarantees, during the movement of the table of the saw 7, here in the lower position, than the plane of the saw table and the plane of the saw blade are cut at an angle of 90º. The top 33 it rests, in effect, during the movement of the table of the saw 7, with the guide element 18. By means of this support guarantees the angle of 90º. In an alternative way, the element of position 32 can be performed in such a way that during the Displacement of the saw table 7 is guaranteed, at least in another position, an angle of 90º between the plane of the table of the sierre and the plane of the saw blade.

Position element 32 is realized here as adjustment ring (figure 6). It is fixed in the element of support 2 in a preferred manner by means of a set screw 3. 4.

Here and in a preferred way, the element of setting 12 is arranged in the front third of the table of the saw 7. This ensures that the adjustment element 12 It can be easily accessed and activated.

In the present case, of the three elements of support 12-14, the adjustment element 12 is arranged on one side of the saw blade 6 and the others supporting elements 13, 14 are arranged on the other side of the saw blade 6. In this way, the force distribution it is optimal, since the adjustment element 12 is supported by a optimal way through the configuration of the guide element 18.

In addition, for improved support of the table of the saw 7, the support element 14 of the two support elements 13, 14 that are on one side of the saw blade 6 is arranged in the front third of the table of the saw 7 and the support element 13 is arranged in the rear third of the table of the saw 7. The support element 13 is in this case essentially diagonal in front of the adjustment element 12.

In addition, the adjustment element 12 and the element of support 13 essentially opposite diagonally to the adjustment element 12 have a larger diameter than the third support element 14. These two supporting elements 12, 13 experience, in effect, in the use case of the oscillating lock and circular saw of table, both a pressure load and a flex load, while the third support element 14 is loaded only to pressure under the provision. The smallest diameter of the third support element 14 is preferred, since this facilitates the arrangement of the support element 14 in the activation handle 24.

The supporting elements 12-14 they have a diameter between approximately 7 mm and approximately 15 mm

For security reasons, on the lower side of the saw table 7 is arranged a protection of the blade of the saw 35, which covers the saw blade 6 also when the table of the saw 7 is displaced to the highest position.

To ensure optimal functionality of the oscillating saw and circular table saw, the aggregate of the saw is additionally rotatable about a longitudinal axis and the oscillating saw and circular table saw are made in the area of the oscillating saw in a corresponding way also as a miter saw.
