Definitions
- the present invention relates to a car body frame straightening apparatus consisting of a frame jig and a body rim clamp having an adjustable attachment to the jig frame and comprising of a pair of jaws which clamp to the body rim.
- rim clamps are assembled from flat and angle profile clamp pieces attached to a frame jig. The attachment takes place using multiple bolts.
- This kind of a rim clamp known in the art is exemplified in Fig. 1 of the patent application.
- the aim of the present invention is to achieve a totally new kind of car body frame straightening apparatus in which the rim clamp is implemented as a single piece allowing quick and easy use.
- the car body frame straightening apparatus in accordance with the invention is characterized by having one jaw of the rim clamp permanently fixed to the body piece of the rim clamp while the other jaw, or the adjustable jaw, is clampable by an eccentric cam lever against the first jaw so that the locking operation of the rim clamp fixes the clamp firmly to the jig frame beam or rail by means of another set of eccentric elements effecting on the jig frame.
- a car body frame can be attached extremely quickly at its rim to the straightening apparatus while the straightening apparatus is simultaneously clamped to the jig frame of the apparatus.
- the use of separate, easily lost fixture pieces, such as iron spacers and bolts become obsolete.
- a preferred embodiment of the invention is characterized in that the body rim clamp attachment to the jig frame beams and clamping to the body rim is implemented with the help of a locking lever belonging to the rim clamp, with the pivoting shaft of the lever carrying an eccentric member, such as an eccentrically placed shaft, whose eccentric rotation is effective on the movable jaw; and that the pivoting shaft carries an eccentric member, such as cam rollers placed eccentrically to the sides of the shaft, with the eccentric movement of the rollers exerting a clamping effect on the jig frame beams; and that the movable jaw is pivotally mounted to the rim clamp so that the movement of the eccentric element placed on its shaft also exerts a clamping effect on the jig frame beams.
- a single locking lever is sufficient for performing all required attachments, that is, the attachment of the body rim to the body rim clamp and attachment of the body rim clamp to the jig frame beams of the straightening apparatus.
- Figure 1 shows the rim clamp of a car body frame straightening apparatus of the prior art.
- Figure 2 shows a rim clamp of the straightening apparatus in accordance with the invention in a side view.
- Figure 3 shows the same element as illustrated in Fig. 2 in a top view.
- Figure 4 shows the same element as illustrated in Fig. 2 in an opened position of the rim clamp.
- the straightening apparatus incorporates a jig beam frame 1 and a rim clamp 2, adjustably attachable to the jig frame, with the clamp comprising a pair of jaws 3, 4 clampably attaching to the car body rim.
- One jaw 3 of the rim clamp is permanently fixed to a body piece 5 of the rim clamp 2, while the other, an adjustable clamp 4, is clampable by means of an eccentric clamping member 6 against the other jaw 2 in such a way that the rim clamp is clamped by virtue of an other set of eccentric elements 7, 8, which exert a clamping effect on the jig frame 1, to attach to the beam frame.
- the attachment of the rim clamp to the jig frame 1 as well as its clamping attachment to the car body rim is effected by a locking lever 9 incorporated with the rim clamp, with the lever carrying on its pivoting shaft 10 the eccentric member 6, such as an eccentrically placed shaft, whose eccentric movement exerts a clamping effect on the movable jaw 4.
- the pivoting shaft 10 carries an eccentric member, which comprises of cam rollers 7 mounted to the sides of the shaft 6, with the eccentric movement of the rollers exerting a clamping effect on the jig beam.
- the movable jaw is pivotally mounted to the rim clamp so that the movement of the eccentric element 8 mounted to the shaft 11 is also effected on the jig frame 1.
- the jaws 3, 4 as well as the eccentric elements 7, 8 release the clamping attachment of the rim clamp from the jig frame beam.
- the rim clamp is adjustable to a desired position on the jig frame beam as well as quickly reattachable to the jig frame and simultaneously to the car body rim.
