Description

General positioning jig

Technical Field

The utility model relates to the technical field of micro-switch detection jigs, in particular to a universal positioning jig.

Background

The micro switch is a device with a tiny contact interval and a quick action mechanism; the switch can be operated by utilizing a preset stroke and a preset force. Because the contact spacing of the switch is relatively small, the micro switch is called a sensitive switch. In the prior art, a micro switch generally comprises a driving rod, a switch shell, a terminal or pin, a movable piece, a static contact or a static contact, a movable contact or a movable contact and other parts. The driving rod can transmit external force to the internal spring structure so as to push the movable contact to realize the switching action; the interval between the stationary contact and the movable contact is generally referred to as contact interval, i.e. OP value; the OP is Operating Position, i.e. the action position is abbreviated as "action position". The OP value is the effective working distance of the micro switch, so the design interval of the contact is usually the main design goal of the micro switch. When the micro switch is in use, the minimum contact interval is required to be selected after meeting the design requirement, and the standard of the contact interval is 0.5mm. In addition, for the similar micro switch structure, the smaller the contact point interval is, the smaller the MD, namely the difference distance is; i.e. the higher its sensitivity, the longer its mechanical lifetime.

Before the microswitch leaves the factory, the contact interval of the microswitch is usually detected, namely the OP value of the microswitch is detected, so as to determine whether the microswitch meets the use requirement. At present, the detection of the OP value of the micro switch is usually carried out by using a measuring tool matched with an operator; therefore, an operator needs to hold the measuring tool with one hand and hold the micro switch with the other hand, and then the data on the measuring tool is read, so that the purpose of detection is achieved. Thus making the operation cumbersome and inefficient. Especially for mass production, the mode of detecting the OP value seriously affects the production efficiency of the micro switch.

Based on this, chinese patent CN218380849U discloses a micro-gap switch OP value detector, and it is including the base, set up detection piece, detection platform, the suggestion module on the base, and detection piece constitutes sliding fit with the base, is provided with the contact piece on the detection platform, and contact piece constitutes electric connection with the suggestion module, one side of detection piece is including the contact fitting surface that is the echelonment profile, the contact fitting surface is including upper limit value detection section, lower limit value detection section respectively along the slip direction of detection piece, the suggestion module is including response module and two suggestion modules, and two suggestion modules can be respectively when upper limit value detection, lower limit value detection are qualified and are reminded. The micro-switch OP value detector can rapidly and accurately distinguish whether the micro-switch OP has an upper limit value fault or a lower limit value fault; so as to meet the requirement that the micro switch avoids manual measurement and is suitable for mass production detection.

However, the above disclosed micro switch OP value detector has a disadvantage of insufficient versatility. Specifically, in the manufacturing enterprises of the micro-switches, the micro-switches are subdivided into various types, and each micro-switch needs to be detected in percentage before leaving the factory so as to ensure the yield of the micro-switches. Therefore, the detecting jig for detecting the OP value of the micro switch also needs to have a great number of models so as to correspondingly match micro switch products of different models. In this regard, the manufacturing enterprises need to put in large production and inspection costs and have a troublesome management.
