Description
Technical field
The present invention relates to a kind of assembly tooling of body of a motor car, particularly relate to a kind of trimming device of body of a motor car assembling.
Background technology
In automobile manufacture industry, there are a lot of defectives in the quality control of body in white welding process, and the series of problems such as distortion, distortion, relatively the panel beating fit-state is bad appear in the sheet metal component material limit after the welding in the solder joint welding process.Notification number is that the Chinese utility model patent of CN201783753U discloses a kind of welding spot-distortion-preventing device, comprises fixture, and the connecting plate that is connected with fixture is provided with face component between connecting plate and the sheet metal component; The technical scheme of this utility model is to increase stress surface when welding, prevent surperficial solder joint torsional deformation, but this scheme also need to be carried out device to each welding operation and install fixing when welding, operating process is loaded down with trivial details, inefficiency, and this device can not guarantee after the welding that panel beating material limit fully can torsional deformation after welding, therefore, still need the panel beating material limit after the welding is repaired.These positions that need to repair are mainly at four door frame material limits, luggage compartment doorframe material limit and the four glass run channel places of vehicle body.Existing processing mode is to rely on manually to knock correction with rubber hammer or iron hammer, the mode of pulling after going to clamp again or with locking pliers is proofreaied and correct one by one, not only operating efficiency is low for such finishing mode, and the state consistency after the finishing just has no idea to guarantee at all, moreover employee's labour intensity is very large.The problems such as the defective that this finishing mode is brought will directly have influence on the assembly quality of car load, general assembly sealing strip assembling can occur not in place, and roof leaking in the car, seal be poor, four glass lifting clamping stagnations and sealing strip come off.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of vehicle body material limit trimming device and uses the material limit trim process of this trimming device, by vehicle assembly shop pneumatic resource commonly used, and the rolling extrusion principle of utilizing roller realizes the finishing to vehicle body material limit, material limit dressing process realizes semi-automation, make dressing process more stable, the finishing state consistency is better, and trimming speed is fast.In addition, owing to adopting pneumatic the driving, labor strength is low.Simultaneously, continuously extruded by what roll, thus avoid above panel beating finishing all quality problems of bringing not in place.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: a kind of vehicle body material limit trimming device, comprise pedestal, the fixed handle that is fixedly connected with pedestal one end, by a fulcrum be slidingly connected on the pedestal in the skewed slot clamping lever, be connected in self-locking mechanism, between clamping lever and the pedestal and be articulated on the pedestal and the driving wheel and that is provided with a drive end is articulated on described clamping lever one end and is movably connected in the driven pulley in the guide hole on the pedestal; The axis of described driven pulley and driving wheel is parallel to each other; The oblique angle of skewed slot is greater than 0 ° and less than 45 °.Clamping lever rotates and slides along skewed slot by fulcrum in clamping process, drives driven pulley and moves to driving wheel along guide hole, clamps vehicle body material limit and by the self-locking mechanism self-locking with driving wheel.Trimming device behind the clamping material limit by external impetus, such as the driving of pneumatic impact spanner, makes it roll and extruding along the material limit by the drive end on the driving wheel, the finishing on realization vehicle body material limit.This device has the finishing high conformity, and trimming speed is fast, and alleviates workman's labour intensity.
As a kind of preferred technical scheme, the oblique angle of described skewed slot is 25 °～40 °.Particularly, this oblique angle is 30 °.Strengthen this oblique angle and can accelerate driven pulley to the close speed of driving wheel, but can increase the force of sliding friction of fulcrum and skewed slot.25 °～40 ° oblique angle is the translational speed of balance driven pulley and the problem of force of sliding friction preferably, makes operating personnel more laborsaving when compressing clamping lever.
For device can be resetted easily and reliably, between described fixed handle and clamping lever, also be provided with a back-moving spring after finishing the finishing of material limit.
As a kind of preferred technical scheme, described pedestal comprises a seat board and a gripper shoe relative with seat board; Described guide hole is arranged on the described seat board and in described gripper shoe and is provided with the guide groove corresponding with described guide hole; Described skewed slot is arranged on the described seat board and is close to described guide hole; One end of the drive end of described driving wheel and pawl pivot stretches out described gripper shoe.By the pedestal of this plank frame, processing that can more convenient pedestal, economical with materials more can make things convenient for the assembling of device.
As a kind of preferred technical scheme, described self-locking mechanism comprises a ratchet that is fixed on the ratchet on the described fulcrum and is articulated on the described seat board and meshes with described ratchet under the effect of a flexible member.Adopt the self-locking mechanism of this structure have advantages of simple in structure, locking power is large, reliability is high.
As further optimal technical scheme, also comprise the roll sleeve that is arranged on the described driven pulley pivot and in described guide hole and guide groove, rolls respectively.By this roll sleeve, driven shaft is rolled in guide hole or guide groove, the movement of driven pulley is controlled with being convenient to more flexibly.
As optimal technical scheme further, but described drive end is an Application standard sleeve or pulls the hand-driven drives structure.Thereby, make this trimming device have higher adaptability.
A kind of technique of using described vehicle body material limit trimming device to carry out the finishing of vehicle body material limit may further comprise the steps:
A. the hand-held trimming device of operating personnel places between driven pulley and the driving wheel material limit panel beating;
B. operating personnel hold fixed handle with one, and clamping lever is pressed down clamping, driven pulley is moved along guide hole to driving wheel and cooperate pressing material limit panel beating with driving wheel; Driven pulley self-locking under the self-locking mechanism effect;
C. operating personnel use external impetus to pass through described drive end and drive the driving wheel rotation, and driven pulley and driving wheel are rolled along vehicle body material limit;
D. after finishing finishing, operating personnel compress clamping lever again, and make the self-locking mechanism release; Driven pulley resets along guide hole, and trimming device is separated with material limit panel beating.
Use this trim process, trimming device is evenly carried out along the material limit the finishing on material limit, make the material limit flatness after the finishing better, dressing efficiency is higher, has also reduced workman's labour intensity simultaneously.
Technical scheme of the present invention, utilize two driving wheels that mutually clamp and the rolling extrusion of driven pulley, make device push finishing to material limit crushed element under under external force drives, rolling along vehicle body material limit, make finishing have better uniformity, trimming speed is fast, simultaneously, because this device can drive by air pump or aerodynamic moment spanner, carry out a step and alleviated workman's labour intensity.
