Description
Technical Field
The invention relates to the technical field of automobile manufacturing, in particular to a positioning and pressing tool for assembling automobile sheet metal parts.
Background
When the automobile part assembly is assembled, the width direction size of a part sheet metal part needs to be controlled, general sheet metal part assembly is carried out by using a profiling tool, the profiling tool comprises a vertically arranged profiling, a positioning pin for positioning the sheet metal part is arranged on the profiling, a locking block for locking the sheet metal part from the upper part when the sheet metal part is leaned against is further hinged on the profiling, the locking block is connected with a handle, a limiting stop block for limiting the position of the locking block is arranged at the position of the profiling below the locking block, when the sheet metal part is assembled, the sheet metal part is placed on the profiling tool to carry out non-pressing force, the positioning pin moves back and forth due to vibration in the tightening process, and the sheet metal part moves under the condition that the sheet metal part does not have the pressing force, so that the assembly precision is poor; therefore, the pressing and holding are needed; meanwhile, the assembly can be quickly switched to ensure the rhythm of rolling production. Therefore, a device capable of well positioning and pressing the sheet metal part needs to be designed to solve the problems of slippage and quick switching during assembly of the part assembly.
Disclosure of Invention
The invention aims to solve the problem that the assembly quality and the assembly speed are influenced by the movement and the play of a sheet metal part in the conventional automobile assembly.
In order to solve the problems, the technical scheme of the invention is as follows: this automobile assembling auxiliary fixtures is including erectting the profiling that sets up, be equipped with the locating pin that is used for fixing a position the sheet metal component on the profiling, it has the lock piece that is used for the sheet metal component to lean on the time-out to follow locking sheet metal component still to articulate on the profiling, the lock piece is connected with the handle, the profiling is equipped with in the position under the lock piece and is used for the restriction the limit stop of lock piece position, through spring coupling on the profiling the lock piece leans on under the tight state with the sheet metal component locking sheet metal component, the locating pin crosses the profiling and in the profiling reaches lock piece junction concave yield, the profiling deviates from one side of lock piece the locating pin is equipped with the screw thread section, the screw thread section of locating pin is connected with one and is used for from one side with the sheet metal component the lock nut that the profiling compressed tightly.
In the above technical solution, a more specific solution may be: and an inclined chamfer is arranged at one end of the positioning pin, which is positioned at one side of the profiling, where the locking block is arranged.
Further: the spring is a tension spring.
Further: and a base is arranged at the bottom of the profiling.
Further: the locking nut has a handle portion.
Due to the adoption of the technical scheme, compared with the prior art, the invention has the following beneficial effects:
when this automobile assembling auxiliary fixtures used, the sheet metal component leaned on the profiling, moved the handle and pulled down the locking piece, made the locking piece from the top compress tightly the sheet metal component and gone into the locating pin, and the spring was in tensile locking state this moment, and twist lock nut is in order to lock the sheet metal component from one side, and lock nut is loosened after finishing in processing, pulls up the locking piece, switches next sheet metal component. The automobile assembly auxiliary tool is clamped at the concave part of the positioning pin by the spring tensioning locking block, so that the relative motion between the positioning pin and the locking block is limited; the positioning pin is recessed at the position which transversely penetrates through the explorator, and the relative motion between the positioning pin and the explorator is limited after the locking nut is locked, so that the stability and the working reliability of the positioning pin are greatly improved no matter the positioning pin axially moves or radially slides, and the processing precision is well ensured; and the time to switch to the next workpiece is shortened. The automobile assembly auxiliary tool is simple and convenient to operate, high in reliability and short in switching time, and can be used for assembly line production.

fig. 2 is a top view of an embodiment of the present invention.
Detailed Description
The embodiments of the invention will be described in further detail with reference to the accompanying drawings:
the automobile assembly auxiliary tool comprises a profiling 3 which is vertically arranged, a base 1 is arranged at the bottom of the profiling 3, a positioning pin 4 used for positioning a sheet metal part is arranged on the profiling 3, a locking block 7 used for locking the sheet metal part from the upper part when the sheet metal part leans against is hinged to the profiling 3, a handle 2 is connected to the locking block 7, a limit stop 8 used for limiting the position of the locking block 7 is arranged at the position of the profiling 3 below the locking block 7, the locking block 7 is connected to the profiling 3 through a spring 6 to lock the sheet metal part in the sheet metal part leaning state, the spring 6 is a tension spring, the positioning pin 4 transversely penetrates through the profiling 3 and is recessed at the joint of the profiling 3 and the locking block 7, the spring 6 is used for tensioning the locking block 7 to be clamped at 4-1 of the recessed position of the positioning pin 4, and relative movement between the positioning pin 4 and the locking block 7 is limited. The locating pin 4 of one side that profiling 3 deviates from locking piece 7 is equipped with screw thread section 4-2, screw thread section 4-2 of locating pin 4 is connected with one and is used for the lock nut 5 that compresses tightly the sheet metal component to the profiling from one side, lock nut 5 has handle portion 5-1, conveniently turn round the elasticity turn round lock nut 5, locating pin 4 is in crossing 3 recesses of profiling, the relative motion between locating pin 4 and the profiling 3 has been restricted again after lock nut 5 locks, no matter axial drunkenness or radial slip, all make the stability of locating pin 4, the operational reliability has been promoted greatly, the machining precision has obtained fine assurance.
