The production process of the boom of the forklift truck/loader and its finishing and fixed tooling

Abstract

The invention relates to a production process of a movable arm of a forklift loader / loading machine and a fine processing fixing tooling of the movable arm. The fixing tooling comprises a base, a main support frame and four fixing mechanisms, wherein the main support frame and the four fixing mechanisms are assembled on the base, a rocker arm connecting hole of the movable arm is assembled in the top of the main support frame through a pin haft, and the four fixing mechanisms are respectively used for fixing the four arm ends of the movable arm. According to the production process, the formed movable arm is obtained after the materials are manufactured through the work procedures of numerical control cutting, point welding, full welding, correction, coarse and fine processing and the like. The technical scheme provided by the invention is adopted for preparing the movable arm, the coaxiality of corresponding holes in the movable arm is effectively improved, the form and location tolerance of the movable arm is small, the rejection rate is effectively reduced, the product quality is also perfectly ensured, the problem that the form and location tolerance correction dimension precision cannot be ensured due to the welding deformation quantity of the original process is avoided, the dependence on experienced workers with special skills in the production and service processes is also reduced, the production efficiency is effectively improved, and the production cost is reduced.

Description

Technical field [0001] The invention relates to a production process of a boom and a fixed tooling thereof, in particular to a production process of a boom of a forklift / loader and a finishing fixed tooling thereof. Background technique [0002] Reference figure 2 , image 3 , The boom 4 of the forklift / loader is cut into several parts with different shapes according to the size requirements of the product drawings, and then spot welded into a semi-finished boom according to the assembly drawings. The boom 4 includes a left main board 41 and a right main board 42. The left and right main boards are fixedly connected as a whole through the main beam 43 and the connecting board 44. The left and right main boards have a symmetrical structure. The front end of the main board is drilled with a front connection hole 4a, and the rear end A rear connecting hole 4d is provided. The middle and rear parts of the left and right main boards are respectively welded with an assembly 45, the ass...

AI Technical Summary

Problems solved by technology

[0003] The invention provides a production process of the boom of a forklift truck / loader and its finishing and fixing tooling, so as to overcome the unsatisfactory coaxiality of the corresponding holes on the left and right main boards existing in the existing production process of the boom , the shape and position tolerance is very large, and most of the product booms cannot meet the requirements, requiring very experienced technicians to do a lot of calibration work, the production efficiency of the boom is low, and it is extremely dependent on experienced calibration technicians. high cost issues
