CN-224230879-U - Rear overhang lower support bracket gauge

Abstract

The utility model relates to a rear suspension lower support bracket gauge which comprises two bottom boxes, wherein a hydraulic support adjusting mechanism is arranged between the two bottom boxes, a stabilizing mechanism is arranged on each bottom box, a plurality of wheels are fixed at the lower end of a bottom plate, the stabilizing mechanism comprises an air cylinder and a lifting box which is arranged in the bottom boxes and is fixed, the top of the inner side of each box is fixed with the air cylinder, and the output end of each air cylinder is fixed with the lifting box. According to the rear suspension lower support bracket detection tool, four threaded rods and threaded sleeves which are annularly distributed are arranged in the lifting box, and the four support legs can synchronously move outwards or inwards and are unfolded for support by matching with synchronous meshing transmission of the driving bevel gear and the driven bevel gear. Compared with the unilateral threaded rod support of the comparison case, the structure can uniformly disperse the weight of the rear suspension support, avoid the inclination of the device caused by uneven stress, and particularly remarkably improve the stability of the detection tool during working when the supporting points are asymmetric or the rear suspension weight is unevenly distributed.

Description

Rear overhang lower support bracket gauge Technical Field The utility model relates to the technical field of detection tools, in particular to a rear suspension lower support bracket detection tool. Background Rear underslung mounts are commonly used in the description of vehicle suspension systems, which refers to a design in a vehicle suspension system, commonly used for the rear axle, for supporting the suspension of the vehicle to ensure stability and reliability of the vehicle suspension system, which design helps to improve handling and stability of the vehicle, particularly during high speed travel or when jounce is encountered. In the related art, chinese patent document with application number CN202420427923.4 proposes a rear suspension lower support bracket checking fixture, which adjusts the length of the telescopic rod according to the actual situation by a worker, adjusts the distance between two hydraulic cylinders, rotates an adjusting knob to fix the length of the telescopic rod after the adjustment is completed, then drives a device to move to a proper position by a pulley on the lower surface of a placing plate, rotates a rotating handle after the movement is completed, drives a chassis to lift a thread by a threaded rod, supports the device, and finally controls the hydraulic cylinders to operate by a control valve, so that the rear suspension lower support is supported to the proper position. The device is supported by a single-side threaded rod chassis through a stabilizing mechanism, the device is easy to incline due to uneven stress in the lifting process, particularly when supporting points are asymmetric or rear suspension weights are unevenly distributed, the stability is poor, the adjustment efficiency is low, a rotating handle is required to be manually rotated to drive the threaded rod to lift, the operation is tedious and time-consuming, the device is difficult to quickly adapt to different maintenance scenes, the moving and stable switching is inconvenient, the cooperative property of a pulley and the chassis is insufficient, the pulley braking mechanism is not clear, and the supporting failure possibly occurs due to the sliding of the pulley in the working state. Disclosure of utility model The utility model mainly aims to provide a rear suspension lower support bracket gauge which solves the problems in the background technology. The rear suspension lower support bracket gauge comprises two bottom boxes, a hydraulic support adjusting mechanism is arranged between the two bottom boxes, a stabilizing mechanism is arranged on each bottom box, and a plurality of wheels are fixed at the lower end of each bottom plate; The stabilizing mean includes the cylinder and sets up in the lift box of base case internal fixation, and the inboard top of box is fixed with the cylinder, and the output of cylinder is fixed with the lift box, and the inboard middle part rotation of lift box is installed and is initiative bevel gear, and the lift box internal fixation has four fixed blocks that are annular distribution, rotates on the fixed block and installs the threaded rod, and threaded connection has the screw sleeve on the threaded rod, and the one end of threaded rod is fixed with the driven bevel gear with initiative bevel gear engaged with, and the tip downside of screw sleeve is fixed with the supporting leg. Further, sliding grooves for the threaded sleeves to move are formed in two sides of the box body. Further, a driving motor for driving the drive bevel gear to rotate is fixed on the lifting box. Further, a guide groove is formed in the inner side of the lifting box, and a sliding block in sliding fit with the guide groove is fixed at the lower end of the threaded sleeve. Further, the thread sleeve is consistent with the thread matching direction of the threaded rod, and the axial installation direction of the threaded rod enables the supporting legs to be unfolded when the thread sleeve moves outwards and folded when the thread sleeve moves inwards. Compared with the prior art, the technical scheme of the application has the following beneficial effects: According to the rear suspension lower support bracket detection tool, four threaded rods and threaded sleeves which are annularly distributed are arranged in the lifting box, and the four support legs can synchronously move outwards or inwards and are unfolded for support by matching with synchronous meshing transmission of the driving bevel gear and the driven bevel gear. Compared with the unilateral threaded rod support of the comparison case, the structure can uniformly disperse the weight of the rear suspension support, avoid the inclination of the device caused by uneven stress, and particularly remarkably improve the stability of the detection tool during working when the supporting points are asymmetric or the rear suspension weight is unevenly distributed.
