DE835879C - Puller for pole terminals of accumulators, for ball bearings, gears, discs and. like - Google Patents

Description

The invention relates to a two- or multi-armed puller for pole terminals of accumulators, for ball bearings, gears, discs and the like with hinged in a cross piece Poor.

The previously known two- or multi-armed pullers for gears, belt pulleys, ball bearings and the like have due to their particularly strong design and manufacture from forgeable

ίο Steel weighs a lot and is therefore suitable less for pulling off smaller objects, such as pole clamps from electric batteries and the like. This disadvantage is avoided according to the invention in that the arms are made of high quality Sheet steel punched and stored in several layers one above the other in a cross piece. The puller bridge, which forms the crosspiece, is also made of strong sheet steel on cold Ways shaped. But it can also be made of other material, e.g. B. malleable cast iron.

According to the invention, the gripper arms carry projecting lugs at their upper end which they fit into a groove-shaped recess in the mfttter-like guide piece of the spindle protrude to quickly open and close the gripper arms by sliding the nut lengthways in the crosspiece with simultaneous stroke limitation of the spindle.

An example embodiment of the subject matter of the invention is shown in the drawing. It shows

Fig. Ι a two-armed puller according to the Invention in front view,

Fig. 2 is a side view of the same,

Fig. 3 is a central longitudinal section through the puller according to Fig. 1 with spread apart Grapple arms and

Figure 4 is a plan view of the puller with the arms closed.

The two-armed puller according to the invention consists of a cold-molded one Cross piece 1, which forms a bridge on which the gripper arms 3 are formed by means of rivets or screws 2 stamped, high-quality sheet steel are articulated. The arms 3 carry on their upper End protruding lugs 4, with which they are in a groove-shaped recess 5 of the nut-like Guide piece 6 of the spindle 7 protrude. This makes it possible to move it lengthways the nut 6 in the crosspiece 1 to quickly open and close the gripper arms 3. the Lugs 4 of the arms 3 limit the stroke of the spindle 7 to a desired extent. When closed Gripper arms 3 are made by turning the spindle carrying a thread 8. 7 removing the Workpiece, for example the pole terminals, under which the gripper arms 3 with their inward grab the drawn tips 9. Slipping of the gripper arms 3 is not possible because they are tightened the spindle 10 absorbs the counter pressure from the lugs 4 and thus the gripper arms always be pressed more firmly under the body to be withdrawn. To pull off the clamp, washer or the like, the spindle 7 is rotated. The spindle is turned by means of an on the square 10 same attachable handle. To prevent the spindle tip from penetrating too deeply into the soft To prevent the pole terminal when pulling off the latter, is to have a twist 11 At the top of the spindle 7 a pressure disk 12 is placed, which reduces the bearing pressure of the spindle 7 distributed.

Instead of the nut 6 accommodating the spindle 7, any other shaped guide piece, for example of a cylindrical shape, an find application.

With the two-armed puller according to the invention, the advantage is offered, the device quickly made from their individual elements and put together in a simple manner. the Use of dies for striking the gripper arms, as is the case with the previously known pullers was necessary, is discontinued. The cold way of producing the puller Punching out the individual parts of the same from strong sheet metal makes the production of the tool cheaper considerable. In addition, these are now particularly difficult to obtain heating material for saved the dies and these themselves.

Patent claims:

1. Two- and multi-armed puller for Pole terminals of accumulators, for ball bearings, gears, discs and the like with articulated arms attached to a crosspiece, characterized in that the arms (3) consist of high-quality sheet steel punched and in several layers on top of each other in the crosspiece (1) are stored.

2. Apparatus according to claim 1, characterized in that the crosspiece (1) forming Bridge is cold-formed from strong sheet steel.

3. Apparatus according to claim 1 and 2, characterized in that the arms (3) at their wear upper end projecting lugs (4) with which they are in a groove-shaped recess (5) of the nut-like guide piece (6) of the spindle (7) protrude to enable quick opening and closing of the gripper arms (3) by longitudinally sliding the nut

(6) in the crosspiece (1) with simultaneous stroke limitation to enable the spindle (7).

4. Apparatus according to claim 1 to 3, characterized in that the tip of the spindle (7) has a twist for receiving a thrust washer (12) which penetrates too deeply prevents the spindle tip into the pole terminal when pulling the latter.
