Description: A DEVICE FOR ADJUSTING THE STRAIGHTENING BENCH OF THE CAR BODY STRAIGHTENING AND MEASURING SYSTEM The present invention relates to a device for adjusting the straightening bench of the car body straightening and measu¬ ring system which belongs a support to which is transferable vertically, a straightening bench the vehicle is arranged to be mounted on attached to the support and a cylinder for vertical transfer of the support and the straightening bench- When damaged vehicles are repaired with the help of the straigthening and measuring system they are firstly trans¬ ferred on the car body straightening and measuring system and attached with sill clamps there. After this the vehicle is lifted to the desired hight and with the help of the straightening system the damaged areas are pulled in order to straighten the car body. There is a problem in the pre¬ sent systems that the inclination of the straightening bench cannot be adjusted after the vehicle has been mounted on the straightening bench and is lifted on the straightening bench. In the present systems the straightening bench can be in inclined position only when the vehicle is driven or transferred on the straightening bench, but upon this it is turned into horizontal position and a positioning locking is made mechanically. There is a problem that the vehicle often is in such a position that the clamps cannot be immediately attached on the vehicle, but the place for them must be seeked after by placing the clamps in different points. Additionally there is a problem, that the vehicle is in the horizontal position during the whole repair preventing the effective handling from all the sides. It is an object of the present invention to introduce a device for adjusting the inclination of the straightening bench with help of which it is possible in an easy, simple and trustful way to adjust the the bench inclination. Furt- her ore, it is an object of the invention is to introduce a device by operating of which the straightening work gets easier than before. The goal set for the invention is achieved through the device which is characterized by what is stated in the appended claims. According to the invention to the device belongs a cylinder attached in one end of the straightening bench in order to adjust the inclination. With the help of the cylinder the straightening bench can be turned to the different angles while the straightening bench is in different hights. The device is simple and its operation easy and trustful. In one preferred embodiment of the invention one end of the cylinder is attached to the support. Then the cylinder moves with the support and is easily available. In the other preferred embodiment of the invention one end is attached to the slider, which is fixed to the straigh¬ tening bench using the construction allowing moving lenght- wise. Addiotionally a support arm which is attached to both the slider and the support belongs to the device. Then the cylinder is with the straightening bench, but by the help of the support arm attached to the support. The operation of this kind of a device also is easy and simple. The invention is explained more accurately referring to the attached drawings where fig. 1 shows an embodiment of the device according to the invention placed as a part of the car body straightening system while the straightening bench is in different hights, fig. 2 shows the device according to the figure 1 while the straightening bench is in different angles of gradient, fig. 3 shows the device according to the figures 1 and 2 while the car is mounted on the straightening bench and the straightening bench is in different positions, fig. 4 to 7 show the straightening system where the device according to the invention has been used, and fig. 8 presents another embodiment of the device according to the invention attached to the straightening bench. To the car body straightening system parts presented in the figures 1 to 3 belong a frame pipe 10, a support 1 which is an innerpipe and partly placed in the frame pipe having the construction allowing moving heightweise, a straightening bench 2 attached to one end of the support having the const¬ ruction allowing the cylinder end rotate or a cylinder 4 attached to the frame pipe and the straightening bench or to the inner pipe. Additionally to the straightening system belongs a cylinder 6, which is at one end 5 turnable at¬ tached to the straightening bench 2 and at the other end 7 turnable attached to the support 1. There is a vertical groove made in the frame pipe 9 which enables the cylinder 6 to move with the inner pipe l following its hight. The cylinders 4 and 6 are hydraulic cylinders. The straightening bench in different positions is presented in the figures; according to the figure 1 the straightening bench can be adjusted to the desired hight with the help of the cylinder 4. According to the figure 2 the straightening bench 2 can be inclined with the help of the cylinder 6 in a desired way either upwards or downwards in order to adjust the position of the car in relation to the car body straigh¬ tening system. This is illustrated also in the figure 3, where the car 3 is mounted on the straightening bench. A straightening system the device according to the invention has been used with is presented in the figures 4 to 7. The figure 1 presents the straightening system where the straig- htening bench 2 has been inclined in the direction of the bench 11 of the car. A straightening bench turned into the horizontal position is presented in the figure 5. A straigh- tening bench lifted to the work position is presented in the figure 5 and the figure 7 presents both a straightening bench and a vehicle inclined backwards. In the adaption according to the figure 8 one end 7 of the cylinder 6 is attached to the slider 8. The slider is placed on the straightening bench and can to be transferred follo¬ wing its length. The other end of the cylinder 5 is attached to the straightening bench. Additionally the support arm 9 which is attached to the slider 8 and to the support 1 using the construction allowing turning belongs to the device. The support is an inner pipe vertically placed in the frame pipe also in the adaption. By moving the hydraulic cylinder 6 it is possible to incline the straightening bench to two diffe- rent angles so that the straightening bench 2 turns suppor¬ ted by the support arm 9 upwards or downwards. The invention is not restricted to the advantageous embodi¬ ments but it may vary within the scope of the inventional idea formed by the claims.
