Drive device, vice, and method for operating

Abstract

The invention relates to a drive device comprising a drive for a vice, a coupling device, and a socket wrench rotatable about an axis, in which the socket wrench is movable in the direction of the axis. It also relates to a vice with a side on which a drive spindle is arranged, which has a coupling device counterpart arranged on the side of the drive spindle. Furthermore, the invention relates to a device comprising a drive device that is positively connected to the vice, and to a method for operating such a device.

Description

[0001] The invention relates to a drive device with a drive for a vice, a coupling device and a socket wrench rotatable about an axis, a vice with a side on which a drive spindle is arranged, a device with a drive device and a vice and a method for operating such a device.

[0002] The invention is based on the object of improving such devices and methods.

[0003] This is achieved with devices according to claims 1, 6 and 10 and a method according to claim 11. Advantageous further developments are the subject of the subclaims.

[0004] The task is, in particular, to attach a drive to a vise quickly and without tools. This allows the vise to be operated manually with a key for adjustment and setup, and then automated for series production. An interchangeable adapter plate can be used to operate almost all vises.

[0005] An advantageous embodiment is shown in the drawing and is described below.

[0006] The Figures 1 and 2 show the drive with an interchangeable adapter plate 1 and a vise with matching mating pieces 2, which can be designed as knobs. Three threads must be made in the vise to mount the mating pieces. The mating pieces can also be pressed in without a thread.

[0007] The Figure 3Shows the docking of the drive before the adapter plate is positively locked. The drive socket 3 is axially movable and, when retracted, is positioned in front of the vise spindle 4.

[0008] The Figure 4 shows the drive "docked." The advantage of this arrangement is that the socket wrench is moved over the spindle 5, thus locking and securing the adapter plate to the vise. The axial displacement of the socket wrench is achieved via a rotary handle 6 with an internal threaded rod (not shown). The displacement can also be achieved via a button, motorized, or with a pneumatic or hydraulic cylinder.

[0009] The drive is docked and locked manually, but the vice is then closed or opened electrically, pneumatically or hydraulically.

[0010] There are two scenarios: 1. The worker manually places the components in the vise, then closes / opens the vise using two buttons on the back (not shown). The mushroom head is an emergency stop button. This ensures that the workpiece is always clamped firmly and reliably, and the worker can operate the vise ergonomically and without exerting any force. 2. A robot is positioned at the machine that inserts the component. The robot then controls the drive and opens / closes the vise. The buttons are then inactive. This has the advantage that a robot can still hold the part in the vise during the opening / closing process, making the entire process particularly fast.

Claims

1. Drive device with a drive for a vice, a coupling device and a socket wrench rotatable about an axis, characterized by , that the socket wrench can be moved in the direction of the axis.
