Machining method of pallet wear-resistant plate junction holes

Abstract

The invention relates to a machining method of pallet wear-resistant plate junction holes. The machining method includes the steps that firstly, according to sizes marked in a machining drawing, a pallet wear-resistant plate junction hole sample plate is manufactured, a steel plate with the thickness being 3-4 mm is adopted, the position tolerance of sample plate holes is + / -0.05, and positioningblocks are arranged on the top of the sample plate and at the positions corresponding to a pallet body fence plate groove and a sealing device groove; and secondly, after the pallet body fence plate groove and the sealing device groove are completely machined, the two side faces of a pallet body are clamped in the pallet body fence plate groove and the sealing device groove through the positioningblocks of the sample plate, and according to the positions of the sample plate holes, lineation is conducted and the pallet wear-resistant plate junction holes are machined. By means of the method, the precision requirement is ensured, rapid positioning is achieved, and work of operators is facilitated. Preinstallation does not need to be conducted any more, work procedures are reduced, the wear-resistant plate preinstallation labor amount of bench workers is decreased, and the size measurement labor intensity of lineation machining personnel is lowered. The machining time is saved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a method for processing a joint hole of a wear-resistant plate of a sintering trolley. Background technique [0002] The sintering trolley occupies a huge proportion in the sintering production line, and each production line has more than 100 sets. The wear plate is a key component on the trolley. It itself has been closed on the side of the car body, while the upper part is in contact with the fence, and the lower part is in contact with the sealing device. During the production and operation of the trolley, the wear-resistant plate on the side is also the main working contact surface. The friction between the trolley and the trolley is mainly to grind the wear-resistant plate, so the wear-resistant plate must adopt the quenching and tempering plus surface quenching heat treatment process. In this way, the strength and hardness of the wear plate can be improved. In additi...

AI Technical Summary

Problems solved by technology

There are following disadvantages: (1) the drilling mold is heavy and inconvenient to use

For the operator in the process of processing, it is necessary to frequently move and place the drilling mold, which increases the labor intensity, and the operator does not like to use it.

(2) Low production efficiency

It is inconvenient for the operator to locate, resulting in longer working hours and affecting production efficiency

(3) The drill sleeve needs to be replaced frequently

In order to ensure the machining accuracy, the drill sleeve needs to be replaced frequently, which increases the cost of materials and processing
