Embodiment 1

[0032] Example 1: see figure 1 , an assembly mold for the main roller shaft of a forklift fork frame, including a frame 1, a first positioning mechanism 3, and a second positioning mechanism 13;

[0033] The frame 1 is a rectangular frame formed by splicing four side panels;

[0034] The two opposite side plates of the frame 1 are respectively provided with more than two first positioning mechanisms 3 and more than two second positioning mechanisms 13, and the side plates of the frame 1 provided with the first positioning mechanisms 3 are the first side plates 15. The frame 1 side plate provided with the second positioning mechanism 13 is the second side plate 14; the two or more first positioning mechanisms 3 are arranged on the same level, and the first positioning mechanism 3 and the second positioning mechanism 13 are one One correspondence, and the first positioning mechanism 3 and the second positioning mechanism 13 are arranged symmetrically;

[0035] The first posi...

Embodiment 2

[0043] Example 2: The first side plate 15 is provided with three first positioning mechanisms 3 , and the three first positioning mechanisms 3 are set according to the installation position of the main roller shaft 10 , and the rest of the structure is the same as that of the first embodiment.

Embodiment 3

[0044] Example 3: The bottom surface of the first side plate 15 is provided with two third positioning pins 9, and the two third positioning pins 9 are located on the bottom surface of the first side plate 15 on one side of the step seat 5, and are connected with the second positioning pins 6. Two-dimensional positioning is formed, and all the other structures are the same as in Embodiment 1.

[0045] Concrete operation steps of the present invention are as follows:

[0046](1) see Image 6 , the two vertical boards 11 are vertically arranged in the middle of the fork frame 12 as required, and the two vertical boards 11 are arranged symmetrically;

[0047] (2) see Figure 4 , Figure 5 Hold the handle 2 and place the present invention on the fork frame 12 so that the two vertical plates 11 are positioned on the frame 1, and the first side plate 15 and the second side plate 14 of the frame 1 are parallel to the two vertical plates 11 respectively. The second positioning p...

Abstract

A jig for assembling main roller shafts of a fork carrier of a forklift is characterized in that a frame is rectangular and is made by splicing four side plates; two opposing side plates of the frame are provided with more than two first positioning mechanisms and more than two second positioning mechanisms, respectively; the first positioning mechanisms are disposed on the same horizontal plane, correspond to the second positioning mechanisms and are symmetrical to the second positioning mechanisms; the first positioning mechanisms and the second positioning mechanisms are identical in structure; each first positioning mechanism is composed of a bushing, a sleeve, a sliding rod, a second stopper, a slider and a first retainer ring, the inner surface of the first side plate is provided with an adjusting base which is parallel to the sleeve and which faces the middle of the frame, and the end of the adjusting base is provided with a first positioning pin; the bottom of the first side plate and the bottom of the second side plate are symmetrically provided with pin components; each pin component comprises a step base, a second positioning pin and a third positioning pin. The jig is simple in structure and convenient to use.

Description

technical field [0001] The invention belongs to the field of mechanical tooling, and in particular relates to an assembly mold for the main roller shaft of a forklift fork frame. Background technique [0002] At present, there are 4 or 6 main roller shafts on the fork frame of a 1-3.5t internal combustion forklift and are assembled and welded with the fork frame. The symmetry and verticality also have precision control requirements. [0003] The existing main roller shaft and the part vertical plate in the fork frame are first assembled into a small assembly, and the small assembly is assembled and welded with the fork frame. This assembly method has the following disadvantages: (1). In the two assembly, the flatness and parallelism of the center line of the main roller shaft exceed the control requirements, and the out-of-tolerance problem needs to be solved by means of correction, and the correction process is complicated; The assembly of the fork frame is complex in ope...
