Problems solved by technology

[0003] In the process of manufacturing forklift mast bearings, the dimensional accuracy of the opposite side roller shaft is very high. The traditional detection method uses measuring tools to detect the product separately. The disadvantages are: the detection efficiency is low, and there are certain errors.

Embodiment Construction

[0009] Such as figure 1 As shown, it includes base plate 1, reference block 2, measurement block 3, front measurement surface a, and rear measurement surface b.

[0010] A reference block 2 and a measuring block 3 are arranged symmetrically on the upper end face of the base plate 1. The inner side of the measuring block 3 has two parallel measuring surfaces, and the distance between the front measuring surface a and the inner side of the reference block 2 is the maximum standard of the side roller shaft. length, and then the distance between the measurement surface b and the inner surface of the reference block 2 is the standard minimum length of the side roller shaft. And there is a smooth transition between the front measurement surface a and the rear measurement surface b.

[0011] Working principle: place the side roller shaft 4 horizontally on the bottom plate 1, roll the side roller shaft 4 forward and pass between the reference block 2 and the measurement block 3, if t...

Abstract

The invention relates to a mould for quickly detecting the size of a fork truck side roller shaft. The mould includes a base plate, and the innovative characteristics lie in that a criteria block and a measurement block are symmetrically arranged on the upper end surface of the base plate; two parallel measuring planes are arranged at the front part and the rear part of the inner side surface of the measurement block; the distance from the front measuring plane to the inner side surface of the criteria block is the standard maximum length of the side roller shaft; the distance from the rear measuring plane to the inner side surface of the criteria block is the standard minimum length of the side roller shaft; furthermore, the front measuring plane and the rear measuring plane are in round and smooth transition. The invention has the advantages that when the mould is in use, the side roller shaft is horizontally placed on the base plate, rolls forwards and passes by the space between the criteria block and the measurement block, and the length of the side roller shaft is between the standard minimum length and the standard maximum length if the side roller shaft can pass by the front measuring plane smoothly, yet cannot pass by the rear measuring plane.

Description

technical field [0001] The invention relates to a detection mold, in particular to a quick detection mold for the size of a forklift side roller shaft. Background technique [0002] Bearings for forklift masts need to realize rotational movement in two directions. Due to the limitation of space, a compound roller structure with two directions of rotational movement in the cross direction is generally used. The conventional bearing has a built-in side roller bracket. Side rollers are installed on the roller bracket. For example, the patent authorization announcement number CN 201250086Y discloses a built-in side roller of a forklift, which consists of a shaft head, a side roller bracket, a side roller, and a side roller shaft. The side roller bracket mounts the side rollers via the side roller shaft. This structure has the advantages of compact structure and small volume, and is widely used in forklift mast bearings. [0003] In the process of manufacturing forklift mast...
