Description

Labor-saving auxiliary assembling tool for automobile

Technical Field

The utility model relates to an automobile assembling field, in particular to laborsaving auxiliary assembly instrument.

Background

In the process of assembling automobile parts, the assembly of some large parts (heavy weight and large volume) often involves the pairing of multiple groups of bolts and nuts, for example: a steering gear (heavy), a vacuum air storage tank (heavy and large in volume), a urea box, a radiator and the like. Because the weight and the volume of the parts are large, the positioning of a large part is generally ensured by adopting a mode of pre-arranging 1-2 bolts in the assembling process, but the pre-arranging time of the bolts is relatively long because the bolts need to be screwed and screwed due to thread matching, and the large part needs to be always supported by hands in the pre-arranging process of the bolts, so that the continuous labor force of staff can be caused, and the ergonomics is poor.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a laborsaving auxiliary assembly tool of car, concrete technical scheme is as follows:

an automobile labor-saving auxiliary assembling tool comprises an intermediate shaft, a handle, a rotating rod and an adjusting pin shaft; the middle shaft is cylindrical, and two ends of the middle shaft are respectively provided with a hexagonal head and a connecting cylinder of a rotating rod; the rotating rod is matched with the connecting cylindrical end through a shaft pin and rotates around the shaft pin; the outer side of the intermediate shaft is provided with external threads which are matched with the internal threads of the handle to enable the intermediate shaft to be in threaded connection with the inside of the handle; an adjusting threaded hole and a hexagonal head through hole are formed in one end of the handle, the external thread of the adjusting pin shaft is matched with the adjusting threaded hole in the handle and abuts against the intermediate shaft, and the hexagonal head penetrates through the hexagonal through hole; the other end face of the handle is a through hole, the intermediate shaft is screwed into the handle from the through hole, and the outer edge of the end face is convexly provided with a clamping face.

Further, the rotation angle of the rotating rod is 0-90 °.

Furthermore, the other end of the adjusting pin shaft is hexagonal.

The utility model discloses a theory of operation:

1. locking: through jackshaft working part and the integrative screw hole that passes work piece 1 of rotary rod and the via hole of work piece 2, wear handle portion clamping face and work piece 1 contact all the time, then rotate 180, utilize the automatic flagging of the gravity of the adjusting pin axle of jackshaft front end, adjusting pin axle and handle portion clamping face are parallel this moment, form reliable centre gripping chamber between adjusting pin axle and the clamping face, work piece 1 and work piece 2 are all in the centre gripping chamber to by the centre gripping chamber pin.

2. And finishing the taking-out step: after the matching of other bolt holes is completed, the auxiliary tool is pushed towards the workpiece to the clamping surface of the handle part to be jointed with the workpiece, the auxiliary tool rotates in the reverse direction for 180 degrees, the rotating rod connected with the middle shaft at the front end of the tool is automatically returned, the tool is taken out, and the steps are completed. The bolt hole assembly is continued to be completed.

The utility model helps to reduce the continuous force of heavy large parts in the assembly process through the rapid auxiliary assembly device, thereby reducing the labor intensity of assembly; the time for assembling heavy parts of large parts with threads in advance is shortened through the quick auxiliary assembling device, and the assembling efficiency is improved. The utility model has the advantages of convenient and simple manufacture, convenient maintenance and low cost; the application range is extensive, under the condition that does not have the hoist, uses this instrument can effectively promote the assembly beat and reduce assembly intensity of labour.
