Description

SLIDING TABLE SAW HAVING A GUIDE MECHANISM

The present invention relates to a sliding table saw, which saw is a workpiece support surface fixed to a machine frame, a circular saw blade rotatably mounted relative to the workpiece support surface, and in particular a guide rail which is a linear rail guide. The linear rail guide includes a guide rail having a rail head and a cross section having a rail web extending from the rail head to the rail base and having a cross section width smaller than the rail head, and the axial direction of the guide rail. It has a guide carriage which is movable along and has an elastic clamping member for securing the guide carriage to the guide rail.

Guide mechanisms of this kind are used in sliding table saws to guide additional members disposed in these fastening members linearly along the fastening members. One application is, for example, where the additional table is linearly guided along the main table of the sliding table saw, which forms the workpiece support surface on which the workpiece is placed, such that the workpiece is a circular saw blade. It may be cut to form a shape by moving relative to it. Another application is when the stop member of the workpiece is linearly guided.

Cutting of the workpiece may require fixing the additional table in one position on the guide rail. In many cases, the guide carriage, which is movable along the axial direction of the guide rail, has a clamping, blocking or breaking member for securing or releasing the guide carriage at a specific position on the guide rail. Clamping members of this kind guided on linear rail guides are known in many applications. Clamping members are often mounted on the side of the guide carriage, acting directly on the linear rail guide by applying braking or holding forces. Known clamping members generally require additional fabrication space. In many cases, the clamping member is also equipped with a separate spring-loaded movable braking member, which makes the clamping member a complex design and susceptible to wood shavings accompanying sliding table saws.

Clamping and braking mechanisms of the kind described above are known, for example, from DE 10 2004 044 052 A1, DE 10 2005 016 719 B4, DE 10 2005 016 724 B4, DE 10 2006 019 410 B4 and DE 10 2006 062 295 B4.

It is an object of the present invention to provide a guide mechanism which is simply designed and particularly suitable for use in a manually operated additional table or stop member of a woodworking machine.

This object is, in accordance with the invention, that the clamping member has two clamping member legs with two inwardly facing clamping jaws, and partially encloses the rail head so that each of the clamping jaws is a rail web. Facing the outer surface of the recess, the recess partially encloses the clamping member in such a manner that the outer surface of the clamping member leg is in contact with the inner surface of the leg of the U-shaped recess, the inner surface being the opening side of the recess. The clamping member interacts with the adjuster member capable of exerting an adjustment force between the carriage body and the clamping member, as a result of which the clamping member is pressed against the inner surface so that the clamping jaws Is achieved by a sliding table saw of the kind specified in the introduction.

Due to the guide mechanism according to the invention, the clamping member is simply designed to be manufactured and the guide carriage is quickly and simply fixed in place. This is achieved by the device and design of the present invention for the elastic clamping member of the guide carriage, as a result of which no separate spring member is required, which minimizes the number of movable parts. The guide mechanism according to the invention is also resistant to dust and dirt, eliminating the need for wipers or seals to prevent dust and dirt. The guide mechanism is also relatively wear free during operation and can be designed with a small overall depth in the axial direction. Finally, the guide mechanism of the present invention does not need to arbitrarily readjust the clamping member and is therefore particularly easy to maintain.

The carriage body is preferably U-shaped and has a base facing away from the opening of the recess and two legs extending from the base to the opening. It is also preferred that the clamping member has a base, from which the clamping member leg extends in the direction towards the guide rail. The clamping jaw may preferably be arranged at the end of the clamping member leg and may have a braking face towards the rail web. In the clamping member position where the clamping jaws clamp the rail web, the braking face is pressed against the rail web.

The guide carriage is preferably fixedly connected to an additional table disposed on the sliding table saw, so that the additional table is mounted to be movable along the guide rail. The guide mechanism is thus used to guide the additional table, which can be fixed in place and released.

According to a first preferred embodiment, the adjuster member projects from one side of the carriage body facing away from the recess into the recess via the carriage body and into the threaded hole of the clamping member. It is designed as an adjusting screw to fix and release the guide carriage. A user-friendly adjuster member of simple design is thus defined, whereby the guide carriage can be fixed in place particularly simply and quickly. The adjusting screw preferably protrudes through the base of the carriage body into the threaded hole of the base of the clamping member in the direction of the opening of the recess. The operator is further given a haptic feeling as to whether the clamping member is fixed. The operator detects when the clamping jaw has reached the fixed position, since it becomes more difficult to turn the adjusting screw. The screw head of the adjustment screw can be designed so that the operator can turn the adjustment screw manually. Alternatively, the adjustment screw can also be adjusted by an automatically controlled rotary motor or an eccentric mechanism.

According to another preferred embodiment, the outer surface of the clamping member 31 has a V-shaped cross section and widens toward the clamping jaw, the inner surface of the recess has a V-shaped cross section and faces the opening of the recess. The wider it gets Particularly suitable structures of the clamping member and the guide carriage are thus defined, which avoids any undercut that can impair the function of the clamping member.

The expression "V-shape" means, in the context of the present invention, that the legs of the clamping member diverge from each other in at least one part in a "V" shape towards the clamping jaw, but the inner surfaces of the recesses in each other in at least one part. Is understood to mean that it emits in the form of a "V". Such V-shaped divergence can be realized linearly, nonlinearly and / or with multiple linear sections.

According to another embodiment, the clamping member has a bias that forces the clamping member leg against the inner surface of the recess to a position where the clamping jaws do not clamp the rail web, wherein the interior of the V-shaped portion of the recess is The face forms at this position an angle smaller than the angle formed by the outer face of the V-shaped portion of the clamping member leg. In this way, the biased elasticity of the clamping member is used in a particularly suitable manner. The clamping member can also be adjusted by the bias in such a way that only a small adjustment path is required to lock the carriage in place. The bias of the clamping member also causes the clamping member to form a component of the force from outside of the recess. The adjuster member can thus be implemented to exert an adjustment force only in the recess. In order to release the clamping member, the adjuster member does not need to apply a force component to the clamping member in the direction outside the recess.

Another preferred embodiment is characterized in that the clamping member is made of metal or plastic in one piece, and the carriage body is made of metal in one piece. This results in an embodiment which is produced particularly cost-effectively and has a simple design. In the context of the present invention, the expression "plastic" is understood to mean a solid made of an organic polymer.

Another aspect of the invention is a guide mechanism, in particular a linear rail guide, comprising a guide rail having a rail head and a cross section with a rail web extending from the rail head to the rail base and having a smaller cross section than the rail head, and the axis of the guide rail. A guide carriage having a carriage body movable along the direction and having a recess in a U-shaped cross section, and an elastic clamping member for securing the guide carriage to the guide rail, the clamping members being two disposed on one clamping member leg, respectively. Two clamping members with two inwardly facing clamping jaws, partially enclosing the rail head so that each of the clamping jaws faces the outer surface of the rail web, and the recess is provided with a U-shaped Partly surrounding the clamping member in such a manner as to be in contact with the inner surface of the legs of the seth; The inner surface is increasingly spaced towards the opening side of the recess, and the clamping member interacts with the adjuster member capable of exerting an adjustment force between the carriage body and the clamping member, as a result of which the clamping member is with respect to the inner surface. It is pressurized so that the clamping jaw clamps the rail web.
