Description

Technical Field

[0001] This utility model belongs to the automotive field, specifically, it relates to an automotive driveshaft hanger mounting device. Background Technology

[0002] Automotive driveshaft hangers are used to fix driveshafts and prevent them from vibrating and shifting. Traditional installation relies on manual positioning and bolt tightening, which has problems such as low efficiency, poor positioning accuracy and high labor intensity.

[0003] In automotive transmission systems, the driveshaft mounting angle is a key parameter affecting power transmission efficiency, universal joint life, and vehicle vibration control. The mounting angle can avoid chassis components and adapt to angle changes during suspension bounce. Research shows that existing technologies typically involve manually installing driveshaft hangers. Driveshaft hangers are usually heavy, making it difficult to quickly install them under the car and manually adjust them to the appropriate mounting angle. Furthermore, during installation, a person is under the car, and the bolts are screwed into the threaded holes upside down. The bolt ends need to be manually straightened to prevent them from being twisted during the tightening process.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0006] A lifting structure is installed above the base.

[0007] The clamping and steering structure is located above the lifting structure. The clamping and steering structure includes a first support block, a second support block, bolt holes, and a first clamping plate. A rotating block for adjusting the direction of the first support block is fixed below the first support block. The second support block is elastically connected to the first support block. Two sets of first clamping plates for clamping the drive shaft hanger are provided at each end of the first support block. A bolt hole is opened at each end of the first support block. Two second clamping blocks for clamping bolts are provided below each of the two bolt holes.

[0008] In a preferred embodiment of the present invention, the clamping and steering structure further includes a second spring, and a plurality of second springs are fixed between the second support block and the first support block, with a guide rod provided inside each second spring.

[0009] In a preferred embodiment of this utility model, the clamping and steering structure further includes a lead screw and a limiting groove. Two limiting grooves are opened on the top surfaces of both ends of the first support block. A first clamping plate is provided above each limiting groove. The bottom end of each first clamping plate is slidably connected to a limiting groove. One side of each limiting groove is rotatably connected to one end of a lead screw. The top surfaces of both ends of the first support block are fixedly connected to the bottom surface of a fixing plate. One end of each lead screw passes through a fixing plate and is threadedly connected to the fixing plate.

[0010] In a preferred embodiment of this utility model, both the second support block and the first support block are semi-circular in shape.

[0011] In a preferred embodiment of the present invention, the clamping and steering structure further includes a first spring, both sides of the two bolt holes extend downwards, one side of each second clamping block is fixedly connected to one end of a first spring, the other end of each first spring is fixedly connected to the extended end of a bolt hole, and a guide rod is provided inside each first spring.

[0012] In a preferred embodiment of the present invention, the clamping and steering structure further includes a U-shaped block and a first servo motor. Each end of the rotating block is rotatably connected to one end of a U-shaped block. The first servo motor is fixed to one side of the U-shaped block by a bracket. The rotating shaft of the first servo motor is fixedly connected to one end of the rotating block. The top surface of the rotating block is fixedly connected to the wall surface of the first support block.

[0013] In a preferred embodiment of the present invention, the lifting structure further includes an electric telescopic rod and a lifting plate. An electric telescopic rod is fixedly installed above the middle part of the base. The output end of the electric telescopic rod is fixedly connected to the bottom surface of the U-shaped block. The two ends of the base are hollow inside and each is provided with a lifting plate. The two lifting plates are slidably connected to the base, and one end of the two lifting plates is fixedly connected to the bottom surface of the U-shaped block.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. The rotating block drives the first support block to rotate, and the hanger rotates accordingly, which can quickly adjust the installation tilt angle and save time. Two bolts pass through the bolt holes and threaded holes of the hanger to fix the hanger to the bottom of the car. Two second clamping blocks clamp the bottom of the bolts, and then use tools to screw the bolts into the corresponding threaded holes. There is no need to hold the bolts upright by hand, which effectively prevents the bolts from being twisted.

[0016] 2. Turn on the power to the electric telescopic pole. The electric telescopic pole will drive the U-shaped block and the upper structure to rise, raising the gantry to under the car. This eliminates the need for manual lifting, saving physical effort.
