CAR ADJUSTMENT DEVICE - RIKTNINGSANORDNING FÖR BIL

The present invention relates to a car straightening device comprising a hydraulic cylinder-driven frame part and an associated rack with hem brackets on which the car is driven, which frame part comprises a horizontal telescopic frame beam with a hydraulic traction pusher, transversely attached thereto. -from the side boom with locking device and the frame tube associated with the frame beam, equipped with a rack with hem brackets for the car to be straightened, and in which the car placed on the rack the adjustment can be performed via the chains attached to the chain links of the vertical booms using the traction-pushing unit of the frame beam or also with the lifting movement of the scaffold by means of a lifting cylinder.

Several devices for straightening a car are already known, and examples of these are the structures known from patent publications FI 53930, DE 922970, DE 21 32 021, GB 1 101 089 and US 3 108 629. These have the disadvantage in particular of their functional impracticality, such as uncomfortable working space and height, the need to always remove the car for different work steps, etc., as well as the high cost due to the complex structure.

The object of the present invention is to eliminate these drawbacks and to provide a device which is relatively simple in construction and which enables the best possible working conditions. The straightening device according to the invention is characterized in that the straightening can also be performed together or separately by means of a rotating cylinder by rotating the stand. The car to be treated can be adjusted to a suitable height and turned to the desired position without detaching the car from the mounting, so that the car can be straightened from different angles by simply turning it on its rotating cylinder, which is hydraulically and quickly operated.

A preferred embodiment of the invention is characterized in that the rotation of the car resting on the rotating cylinder supporting the rack takes place via a rotating plate arranged in a hydraulic cylinder-driven lifting device.

The invention will be described in more detail below with reference to the accompanying drawings, in which

One solution of the car straightening device according to the invention is shown in Figures 1 and 2, which describe the main structural parts of the device. The straightening device consists of a body part comprising, for example, a body beam 1 fixed to the floor by bolts and a vertical body tube 2 connected thereto, which is embedded in the floor. A rotating lifting cylinder 4 is arranged in the body tube 2, the lifting member of which acts inside the tube.

3 76265 a hydraulic cylinder 3 and a hydraulic cylinder 6 connected to the frame beam 1 as a rotating member, which acts on a rotating plate 5 with a pin lock, for example, whereby an adjustable car attached to the frame for correction. The hem brackets 8 are attached to beams 0 connected to the bracket 7, which can be infinitely adjusted and locked in place with bolts.

The actual straightening unit is a traction-pushing unit 13 with inner tubes 13 'and locking pins 14' arranged on the frame beam 1, which unit is driven by a hydraulic cylinder 14. This unit 13 can be adjusted inside the frame beam 1 in the longitudinal direction.

Attached to the end of the tube 13 'of the traction-pushing unit 13 is a vertical boom 9, which is mounted to turn steplessly in the lateral direction. The boom 9 is locked in place by an eccentric locking 11, 23 by means of a button 11 via a locking sector 10, which locking is ensured by a pin locking 11 ', 11 ".

A vertical boom 9 as described above is also connected to another telescopic side boom 26 connected transversely to the frame beam 1 in the same way by eccentric mounting, which is simply provided with, for example, a pin lock 28.

According to Fig. 7, the vertical boom 9 is locked by a lock 25 acting in the locking groove 24. The booms 9 are further provided with a wedge-locked 22 chain link 12 to which the chains attached to the car to be adjusted are connected.

The hem bracket for fastening the car to be adjusted is shown in Figures 3 and 4 and operates in such a way that when the hem bracket is mounted on the beam 0, the spring 27 pulls the fastening jaws 15 open. As the car lands on the jaws, the jaws 76265 are clamped by the bearing pin 16 and the rollers 19, allowing traction in the longitudinal direction of the car. When pulled laterally, the bolt 21 is tightened, whereby the jaw locks into the beam 0 by the action of the tightening piece 20. The jaws 15 of the skirt fastener are provided with supports 17 and all parts are supported on the frame housing 18.

Correction with this device according to the invention takes place as follows:

The cylinder 4 is lowered to the lower position and the removable racks - not shown in the figures - are moved into place. The car is driven onto the racks. The skirt fasteners are installed at the hem of the car. The brackets are lifted into place by the cylinder 4. The racks are removed.

For example, adjust the front, side and backward bending of the car:

Chains are attached to the chain links of the vertical booms 9, which are attached to the bow of the car. Pulled by the traction-pushing unit 13. At the same time, the rack 7 is turned in the direction of twisting by the lifting rotation cylinder, whereby the chain attached to the side boom 9 pulls the bow directly.

Bow upward correction:

The chain attached to the bow of the car is attached at one end to the traction-pushing unit 13. The cylinder 4 is lifted upwards, whereby the bow bends downwards.

Downward deflection adjustment:

The pull-push cylinder 4 is raised. Install a support between the front of the car and the traction unit. The lifting-rotation cylinder 4 is lowered, whereby the bow rises.
