Riveting and positioning tool for chassis of cotton picker

Abstract

The invention discloses a riveting and positioning tool for a chassis of a cotton picker. The riveting and positioning tool comprises a bottom supporting platform, a mounting plate positioning seat, atransverse beam positioning seat, a first flange supporting seat, a second flange supporting seat, a first positioning half shaft, a second positioning half shaft and positioning assemblies, whereinthe mounting plate positioning seat and the transverse beam positioning seat are arranged on the bottom supporting platform, the mounting plate positioning seat and the transverse beam positioning seat extend in the width direction of the bottom supporting platform, the first flange supporting seat and the second flange supporting seat, wherein the first flange supporting seat and the second flange supporting seat are arranged at the end, close to the mounting plate positioning seat, of the bottom supporting platform, the first positioning half shaft is arranged at the top end of the first flange supporting seat, the second positioning half shaft is arranged at the top end of the second flange supporting seat, the mounting plate positioning seat, the first positioning half shaft and the second positioning half shaft are used for positioning a front bridge frame of the chassis of the cotton picker, and the positioning assemblies are correspondingly arranged between the first flange supporting seat and the transverse beam positioning seat and between the second flange supporting seat and the transverse beam positioning seat. According to the riveting and positioning tool for the chassis of the cotton picker, the requirements for machining equipment can be reduced, the machining period can be shortened, meanwhile, the riveting and welding efficiency can be effectively improved, the riveting and welding precision of workpieces can be guaranteed, and the labor intensity of workers can be reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery welding, in particular to a riveting and welding positioning tool for the chassis of a cotton picker. Background technique [0002] The cotton picker is a large-scale agricultural machinery, and the chassis of the cotton picker is its main component, which has the characteristics of large size and large number of parts. [0003] The chassis of the cotton picker is usually composed of three parts: the front axle, the rear axle and the middle frame. The number of parts is large, and it is difficult to locate the parts during riveting. In order to ensure that the tire resistance of the cotton picker is small and the body is evenly stressed during the picking process, it is often required that the centers of the front and rear axles coincide; in order to meet this requirement, the three components must be assembled and welded into a whole before being processed on a large machine.
