Description

Trolley with an adjustable lifting cylinder «·

The invention relates to a trolley which is used for loading machine tools with workpieces of any configuration next to the chassis has an adjustable lifting cylinder with Aufnähnieeinrichtungen for the work piece or pieces. The trolley is there:! on a straight or closed one designed according to the respective work problem Guide track can be moved by means of an otherwise known power drive and takes a rotatable and pivotable clamping plate on, which receives a piston-cylinder unit in an axially displaceable manner. The piston rod head carries the various Gripper and clamping elements.

In the case of a known entry / exit serving the same purpose direction in which the trolley is also guided on a track and receives a piston-cylinder unit, the piston can only be extended and retrieved again. To the piston-cylinder unit in this training In order to be able to issue a twisting movement, the entire piston-cylinder unit must by other otherwise known means be adjusted around the axis, or there must be special adjustment devices for the clamping or gripper members be provided.

It has also already been proposed that two piston-cylinder units be placed on the trolley that is displaceable on the guideway to arrange that remove the finished workpieces after machining of the machine tool in question and feed the workpieces to be machined to the relevant machine tool. This training avoids though the idle stroke or idle travel that inevitably results in the first-mentioned training, but this training is expensive because of the necessary two piston-cylinder units. It also requires two piston rod displacers. The respective second piston cylinder unit can also only be actuated when the respective first unit has been taken out of the work area.

fl These two known trainings can each be

They are only used for certain jobs and are not universal usable.

The invention relates to a new design of a verfahrbaron Trolley that is set up for loading machine tools with workpieces of any shape and for this purpose has an adjustable lifting cylinder with the receiving devices for the workpieces. According to the invention which is taken up by a rotating and swiveling clamping plate =

The piston rod of the piston cylinder unit can be rotated by a drive relative to the lifting cylinder. Ourcii the special rotary drive for the piston rod, which is directly assigned to the cylinder, the otherwise necessary special I- 'eststclleinrichtungen for the piston rods, which previously prevented twisting of the piston rod in the established position and only when. Release allow twisting.

Overall, the new training has the advantage of that with simple means the piston-cylinder unit quickly and safely in any direction v @ r- and determined can be, the receiving devices for the workpieces interchangeable, but otherwise fixed to the piston rod are included. The new training is without any restrictions Can be used for any designed head pieces, especially of frozen parts, sheets or plates. The holding devices are matched or adaptable to the respective material of the workpieces with regard to the holding members. the Training of the power or control drives are known in terms of training and mode of operation, so that a detailed description and illustration of these means can be dispensed with.

The design according to the invention is shown in more detail below with reference to the exemplary embodiments shown in the drawing explained. Show it:

Sin in the basic training otherwise known carriage 1 of a trolley 2 takes a power drive 3 for the rollers of the trolley 2 in the usual Who se. Details of this training are not shown or explained in more detail. A turntable 5 is guided over a round recess 4 of the carriage 1 so that it can be displaced and locked. A rotary clamp bearing 6 is used to fix the turntable. The turntable 5 has two protruding bearing eyes 7, on each of which an eye S of a clamp holder 9 for a cylinder 10 is attached. The turntable 5 also has two protruding cheeks 11, which have an arcuate slot 12 that encompasses up to 90 °. A clamping bolt 12a is guided in the slots 12, by means of which the cylinder 10 can be locked in any open position relative to the turntable 5.

In the cylinder 10, a piston 13 is guided in a sealed manner and adjustable. The cylinder 10 is sealed at least two piston rods 14 arranged parallel and eccentrically to one another. The piston rods 14 lie on the same Diameter with even distribution over its circumference. The piston rods 14 are opposite to the piston 13 The end of the cylinder is led out of this, but otherwise firmly connected to the piston 13. Of the Near the open end, cylinder 10 has a rotating body 16 which is guided in a sealed manner in cylinder 10. The rotating body 16 is supported on both sides by a thrust bearing 17. The jacket groove 15 is traversed transversely by a plug 18, which has a blind hole 19 from both end faces with a has branch 20 led at right angles thereto. Above this blind hole 19 and junction 20 is that of the casing groove 15 limited space divided by a cam 20a and alternately on one side or the other on one Overpressure of a pressure medium source can be connected. The plug 18 has a sealing ring inserted into a casing ring groove 20b 20c, which divides the casing groove 15 into two sections A and B via the cam 20a.

The piston 13 with the piston rods 14 then rotates in the cylinder and is depending on the loading by twisted the pressure medium in one or the other direction of rotation. The cylinder 10 has at the front end and in front of the rotating body 16 a pressure medium connection hole.

Zuolfte the arrangement of three piston rods 14 and due of the stopper 18, 19, 20, the piston rods 14 can with the rotating body 16 in the cylinder 10 perform a rotating movement. The stopper 18, 19, 20 allows fine adjustment to.

The ends of the piston rods 14 protruding from the cylinder even when the piston 13 is retracted are connected by a support plate 22 placed on it completed. This support plate carries the various clamping and interchangeable Holding tools 23. These protruding ends of the piston rods are in front of them by a sleeve 23a passed around them Damage protected.

According to Fig. 3, the trolley 1 with the recorded by it Parts 2 - 23a of a portal support structure with running rails 24 and supports 25 added.

In the embodiment according to FIG. 4, the trolley 1 sits with the parts 2-23 on a running rail 36 of a Double stand 37. Various switch buttons or display instruments 38 are also indicated on the double stand 37, which are used to put the working parts of the trolley 1 into use. The support plate 22 takes replaceable a pincer gripper 28.

In the modification according to FIG. 5, the trolley 1 sits with the parts 2-23 on a rail 32, the running heads 33 roles 34 carry. The support plate 22 accommodates a suction lifter 35 here.

6 shows the trolley 1 with the associated parts 2-23 on a cantilever rail 26 with stand 27, with a pincer gripper 28 interchangeable on the plate 22 is set.

According to FIG. 7, the trolley 1 with the parts 2-23 sits on a hanging rail 40 which is held by angle pieces is ο an electromagnet 42 is arranged on the support plate 23.

As already mentioned, the trolley 1 can be moved by a hydraulic or electric motor. The piston 13 is with the piston rods 14 opposite by pressure medium drive the cylinder 10 adjustable and the rotary body 14 is via the stopper 18, 19, 20 also by a pressure medium drive rotatable. The range of rotation of these parts is about 270 ° and is complete for all requirements that may arise sufficient.
