摘要:
The invention relates to a machine comprising a mechanical guide element (2a, 2b) for guiding the displacement of a first (3a, 3b) and a second device (4a, 4b). Said machine comprises a first drive device (5a, 5b, 10a) for displacing the first device (3a, 3b) along the guide element (2a, 2b), and a second drive device (6a, 6b, 10b) for displacing the second device (4a, 4b) along the same guide element (2a, 2b) as the first device (3a, 3b). The mechanical construction of a machine is simplified due to said invention.

Disclosed is a handling device, especially for positioning a test head on a testing device, including a holder for a test head and a column. Positioning apparatus adjustable in a vertical direction is connected to the test head on the column. The handling device advantageously has a simple and compact structure and an exactly reproducible, smooth movement of the test head, because the positioning apparatus has at least one pair of interspaced articulated arms in which one end thereof is respectively articulated on the holder and the other end thereof is articulated on a carriage which can be displaced in a horizontal direction. The articulated arms can be pivotably arranged around a vertical axis. The carriages can move independently from each other.

The invention relates to a handling device, especially for positioning a test head (40) on a testing device, comprising a holder (30) for a test head (30) and a column (10). Positioning means (20) which are adjustable in a vertical direction are connected to the test head (40) on said column (10). The inventive handling device has a simple and compact structure and is characterized by an exactly reproducible, smooth movement of the test head (40), the reason therefor being that the positioning means (20) are provided with at least one pair of interspaced articulated arms (21a, 22a, 22b) whereby one end thereof is respectively articulated on the holder (30) and the other end thereof is articulated on a carriage which can be displaced in a horizontal direction. The a arms (21a, 22a, 22b) can be pivotably arranged around a vertical axis. The carriages (23a, 23b) can move independently from each other.

A loading and unloading apparatus, in particular for the loading and unloading of presses, comprises a horizontally extending arm which is arranged on a carrier and which is moveable in the direction of its longitudinal axis and also vertically, and which has a gripper device for the parts to be handled. For the acceleration of the loading and unloading procedure, the arm is horizontally moveably guided relative to the carrier, and the gripper device is arranged on a gripper carriage guided on the arm, with the gripper carriage being moveable between the two ends of the arm.

In a linear motion slide unit, it is usable under a heavy load with high precision, or in a light load, an over-stroke amount can be made large. The linear motion slide unit comprises an elongated inner rail having high rigidity, a pair of outer rails attached to be reciprocally movable in an axial direction of the inner rail, and linear motion guides of endless track type structure disposed to be slidable with respect to the inner rail and fixed to the outer rails. A bearing body of the linear motion guide has also high rigidity, and accordingly, the balls mounted inside the endless track is applied with a large preload.

A drilling device for drilling holes in structural steel shapes utilizes a control system having a pair of control pistons to set the drill bit at an optimum distance from the workpiece for repeated drilling of holes through material of a given thickness. The control device responds to position switches sensing the positions of the drill-feed cylinder and the control pistons.

A movable table system comprises a base horizontally mounted on a foundation with an intermediate base engaged with the base through first guides so as to be movable reciprocatively in one linear direction. A movable table is engaged with the intermediate base through second guides similar to the first guides so as to be movable reciprocatively in the same linear direction. A direct-acting type drive is interposed between the movable table and the intermediate base for providing relative movement between the table and the intermediate base. Preferably, the base is mounted on the foundation through vibration absorbers.
