Description

Technical Field

[0001] The utility model relates to the technical field of steering systems, in particular to a rapid positioning tool used for noise analysis of a double-tooth electric steering machine. Background Art

[0002] Due to the different models of vehicles and steering gears, the mounting hole positions of the steering gear and the entire vehicle are also different. Therefore, the steering gear requires different fixtures to fix the position when performing noise analysis. Each time the model is changed, it is necessary to first remove the fixing screws between the steering gear and the fixture, and then remove the fixing screws between the fixture and the cast iron platform. The fixture itself is relatively heavy. Therefore, each time the tester changes the model, it not only takes a lot of time but also involves certain safety risks.

[0003] Based on the above reasons, a universal steering gear positioning fixture was designed. This fixture can adapt to steering gears of different types and specifications under no-load test conditions, effectively improving work efficiency and reducing safety risks in the process of transferring fixtures. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a rapid positioning tool for noise analysis of double-tooth electric steering gears, which can be adapted to steering gears of different types and specifications under unloaded test conditions, thereby effectively improving work efficiency and reducing safety risks in the process of transferring tooling fixtures.

[0005] To achieve the above-mentioned purpose, a quick positioning tool for noise analysis of double-gear electric steering gear is designed, including a clamping tool and a rocker arm tool, and its characteristics are: the clamping tool includes a base plate, a fastening plate, and a positioning shaft, the base plate is connected to one end of the positioning shaft by a bottom bolt, and the other end of the positioning shaft is connected to the fastening plate by a top bolt; the rocker arm tool includes a handle, a rocker arm, and an interface sleeve, the bottom of the handle is connected to one end of the rocker arm, and the other end of the rocker arm is connected to the interface sleeve.

[0006] The clamping fixtures are provided with two.

[0007] The bottom plate is a rectangular panel structure, waist-shaped holes are arranged on the four sides of the bottom plate, and a threaded hole connected with the bottom bolt is arranged on one side of the bottom plate.

[0008] The bottom of the positioning shaft is embedded in the bottom plate, and the bottom bolt passes through the bottom plate and is connected to the bottom of the positioning shaft; the top of the positioning shaft is provided with an internal thread structure connected to the top bolt, and the top bolt passes through the fastening plate and is connected to the top of the positioning shaft.

[0009] The rocker arm has a structure with one end being narrow and the other end being wide.

[0010] The interface sleeve is a cylindrical structure with a waist-shaped through hole in the center.

[0011] Compared with the prior art, the utility model is simple to operate, flexible to adjust, firm and reliable, convenient and practical, and can be applied to various types of steering gear products, has strong compatibility, improves test work efficiency, and ensures the safety of testers.

[0016] The utility model is further described below with reference to the accompanying drawings.

[0017] like Figures 1 to 3 As shown, the clamping tooling includes a base plate, a fastening plate, and a positioning shaft. One end of the positioning shaft 3 is connected to the base plate 1 through a bottom bolt 5, and the other end of the positioning shaft 3 is connected to the fastening plate 2 through a top bolt 6; the rocker arm tooling includes a handle, a rocker arm, and an interface sleeve. The bottom of the handle 7 is connected to one end of the rocker arm 8, and the other end of the rocker arm 8 is connected to the interface sleeve 9.

[0018] There are two clamping fixtures.

[0019] The bottom plate 1 is a rectangular panel structure, waist-shaped holes 4 are respectively arranged on the four sides of the bottom plate 1 , and a threaded hole connected with the bottom bolt 5 is arranged on one side of the bottom plate 1 .

[0020] The bottom of the positioning shaft 3 is embedded in the base plate 1 , and the bottom bolt 5 passes through the base plate 1 and is connected to the bottom of the positioning shaft 3 ; the top of the positioning shaft 3 is provided with an internal thread structure connected to the top bolt 6 , and the top bolt 6 passes through the fastening plate 2 and is connected to the top of the positioning shaft 3 .

[0021] The rocker arm 8 has a structure designed with one end being narrow and the other end being wide.

[0022] The interface sleeve 9 is a cylindrical structure 9-1 with a waist-shaped through hole 9-2 in the center.

[0023] There is a positioning shaft 3 on the bottom plate 1, and the positioning hole on one side of the steering gear can be fixed in the positioning shaft 3 on the bottom plate 1, and the positioning hole on the other side is also fixed in the positioning shaft on the other bottom plate. There is a fastening plate 2 on each side to position and fix the steering gear.

[0024] When it is necessary to install a steering gear of a different type, first remove the fastening plate 2 on the positioning shaft 3 of the tooling, adjust the base plate 1 to a suitable position according to the relative distance of the steering gear mounting holes, put the steering gear into the positioning shaft 3 on the base plate 1, lock the steering gear with the fastening plate 2, and use the rocker arm tooling to cover the input shaft end of the steering gear. After the rocker arm tooling is inserted, the steering gear input shaft is driven to rotate, so as to perform noise analysis during the operation of the relevant steering gear.
