Snap gauge structure in electric hydraulic tool and machining method and assembly-disassembly method thereof

Abstract

The invention provides a snap gauge structure in an electric hydraulic tool and belongs to the field of electric tools. The snap gauge structure comprises an installation hole provided with a first hole end and a second hole end. The snap gauge structure further comprises a snap gauge head and a pressing shaft. The snap gauge head is located at the first hole end. A through penetrating hole is formed in the snap gauge head. The pressing shaft penetrates in from the second hole end. The inner end of the pressing shaft is provided with a stretching-in section capable of stretching into or penetrating out of the penetrating hole. One end of the stretching-in section is provided with a blocking head penetrating out of the penetrating hole. When the pressing shaft is pressed inwards, the snap gauge head goes in toward the inside direction of the first hole end and has a reset trend. The snap gauge head has a first state position and a second state position. When the snap gauge head is in the first state position, the axial motion of the pressing shaft is limited; and when the snap gauge head is in the second state position, the blocking head and the stretching-in section can penetrate out of the penetrating hole. The problems that an existing snap gauge structure is troublesome to replace, and metal debris is produced in the assembly-disassembly process are solved.

Description

technical field [0001] The invention belongs to the field of electric tools, and relates to a clamping die structure in an electric hydraulic tool, a processing method and a loading and unloading method thereof. Background technique [0002] In the field of electro-hydraulic tools, the clamping structure is an indispensable structure. The clamping structure includes a clamping head and a pressing shaft. The function of the clamping structure is to clamp the mold base. The current clamping structure is a pin-type locking structure. Realizing the axial limit of the pressing shaft has many problems in practice, as follows: [0003] Taking electro-hydraulic pliers as an example, if the application number is 2019302031027, the name is the appearance design patent of electro-hydraulic pliers, hereinafter referred to as D1, and if the application number is 2018304939037, the name is the appearance design of hydraulic pliers, hereinafter referred to as D2, such as the stereogram of ...

AI Technical Summary

Problems solved by technology

[0007] The object of the present invention is to solve the above-mentioned problems in the prior art, and provide the clamping structure and its processing method and loading and unloading method in the electro-hydraulic tool, wherein, the clamping structure and its loading and unloading method in the electro-hydraulic tool are convenient for clamping The replacement of the head, the loading and unloading process does not affect the smoothness of the movement of the parts, which solves the troublesome replacement of the existing clamping structure, and the problems of metal debris generated during the loading and unloading process; among them, the processing method of the clamping structure in the electro-hydraulic tool makes the clamping structure It is convenient to process, saves man-hours, and solves the problems of cumbersome processing and many steps in the existing clamping structure.
