A device for ensuring assembly and welding accuracy of steering gear bracket and its use method

Abstract

The invention discloses a guaranteeing device of erecting welding precision of a steering wheel bracket and a using method of the guaranteeing device. The device comprises a vertically arranged rectangular structural framework; one side of the structural framework is provided with a longitudinal limiting mechanism and a cross limiting mechanism; the other corresponding side is provided with the longitudinal limiting mechanism a; the top end of the structural framework is provided with two positioning pins used for inserting to a steering wheel bracket hole, a positioning pin is fixedly arranged at the top end of the structural framework, and the other one positioning pin is arranged on an overturning hinge. The guaranteeing device has the following beneficial effects: by adopting the guaranteeing device, the steering wheel bracket can be placed and positioned once without measurement, the location of all spatial size shape and position can be solved, and the fastening location is realized; during the welding process, position cannot be changed; the production efficiency is high, and the product quality stability is high and free from influence of various changes of workers; the device is reasonable in design, simple in structure, convenient to manufacture, low in manufacturing cost, and suitable for a large batch of production and application.

Description

technical field [0001] The invention relates to a steering machine welding guarantee device, in particular to a steering machine support assembly welding accuracy guarantee device and a use method thereof. Background technique [0002] With the development of society and economy, the progress of scientific level, people's living standards have been continuously improved, and traveling is the main choice for most people to improve their quality of life. However, since most tourist attractions are located in mountainous areas or villages, trains, high-speed trains, and high-speed rails are often not directly accessible. The cost of self-driving tours is high, the routes are unfamiliar, and the tickets are high, which makes travel very inconvenient. Therefore, group tours by coaches have become the best choice. [0003] However, the production of passenger cars is a labor-intensive and technology-intensive industry. Under the current situation of small output and many types, th...

Problems solved by technology

However, since most tourist attractions are located in mountainous areas or mountain villages, trains, high-speed trains, and high-speed rails are often not directly accessible. The cost of self-driving tours is high, the routes are unfamiliar, and the tickets are high, which makes traveling very inconvenient. Therefore, it is best to take a group tour by bus.

[0003] However, passenger car production is a labor-intensive and technology-intensive industry. Under the current situation of small output and many types, the main labor force for production is workers, not robots. Dimensional consistency poses a big challenge. Often due to the accuracy of assembly and welding, during the assembly of the steering wheel column before the final vehicle goes off the assembly line, the left or right plane of the steering wheel is deflected, and the steering wheel column deviates to the left or right. The axis, front or rear deviates from the axis, causing driving work intensity, convenience, appearance and convenience of construction, and ultimately affects the normal use of the bus and the comfort of the driver

[0004] At present, the assembly and welding accuracy of the steering machine bracket is guaranteed by workers' manual measurement. The steering machine bracket is spatial, and it is difficult to guarantee the parallelism, height, front and rear positions, and left and right positions of it and the floor frame at the same time.

[0005] The above commonly used control methods have the following disadvantages: all the dimensions of the steering gear bracket position cannot be guaranteed and measured in place at one time, and the measurement accuracy and size consistency are directly determined by the carefulness and responsibility of the construction workers. Once the workers’ emotions change, or Workers ask for leave and replace others for construction

In addition, there is no rigid fixation during welding after measurement, and it is easy to change position, resulting in lower welding accuracy, so the process quality is not easy to guarantee and control
