Description

A kind of packing ring internal diameter pick-up unit

Technical field

The utility model relates to a kind of pick-up unit, specifically is a kind of packing ring internal diameter pick-up unit.

Background technology

Packing ring internal diameter pick-up unit can detect steel packing ring internal diameter whether in the tolerance allowed band, can eliminate the not workpiece in margin tolerance of steel packing ring internal diameter more quickly, and can be with qualified internal diameter packing ring, greater than qualified internal diameter packing ring, less than the classification of the packing ring of qualified internal diameter.Ordinary gasket internal diameter pick-up unit, it drives the mechanism of detecting is pure mechanical gear structure, this device often need oil and safeguard, and has shortcomings such as volume is big, detection efficiency is low, cost an arm and a leg, and has been difficult to satisfy the High-efficient Production demand.

The utility model content

The purpose of this utility model just is the deficiency at prior art, and a kind of packing ring internal diameter pick-up unit is provided, and it adopts electronic mode to detect, and not only volume is little for it, detection efficiency is high, and simple in structure, cost is low.

Realize that the technical scheme that the utility model purpose is adopted is: a kind of packing ring internal diameter pick-up unit is characterized in that: it comprises a detection platform, an actuating unit, a detection agency, a single chip machine controlling circuit, a display, a keyboard;

Described detection platform, it includes three armed levers, and its three armed levers are respectively first armed lever, second armed lever, the 3rd armed lever, and its first armed lever front end is provided with and detects the hole;

Described actuating unit, it comprises a two-way stepper motor, a gear, a tooth bar, and its gear is installed in the two-way stepping motor rotating shaft, and its wheel and rack bridle joint, its two-way stepping motor are installed on the 3rd armed lever;

Described detection agency, it comprises a replaceable probe, a slide-bar and a slip pipe, on its slide-bar one end replaceable probe is installed, and its slide-bar other end is connected with the tooth bar of actuating unit, its slip pipe is installed on detection platform second armed lever, and its slide-bar places in the slip pipe;

Described single chip machine controlling circuit, it comprises that a control end, shows that output terminal, an input are provided with end, and its control end and two-way stepping motor join, and its input is provided with the termination keyboard, and it shows output termination display.

The utlity model has following beneficial effect: from keyboard, an initial value can be set, its single chip machine controlling circuit drives two-way stepping motor and rotates, the two-way stepping motor driven gear rotates, the gear plectrum carry-over bar takes place to bottom offset, slide-bar slides from slip pipe, replaceable probe is inserted in the packing ring on the first armed lever front-end detection hole, single chip machine controlling circuit writes down the two-way stepping motor rotation information in this process, the computing measured value, and take measured value and initial value comparison, thereby reach a conclusion and be shown on the display.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is a structural representation of the present utility model.

Label 1 is a detection platform among Fig. 1, and 2 is first armed lever, and 3 is second armed lever, and 4 is the 3rd armed lever, and 5 for detecting the hole, and 6 is two-way stepping motor, and 7 is gear, and 8 is tooth bar, and 9 is replaceable probe, and 10 is slide-bar, and 11 is slip pipe.

Embodiment

As shown in Figure 1, a kind of packing ring internal diameter pick-up unit, it comprises a detection platform 1, an actuating unit, a detection agency, a single chip machine controlling circuit, a display, a keyboard; Described detection platform 1, it includes three armed levers, and its three armed levers are respectively first armed lever 2, second armed lever 3, the 3rd armed lever 4, and its first armed lever, 2 front ends are provided with and detect hole 5; Described actuating unit, it comprises a two-way stepper motor 6, a gear 7, a tooth bar 8, its gear 7 is installed in two-way stepping motor 6 rotating shafts, its gear 7 and tooth bar 8 bridle joints, its two-way stepping motor 6 is installed on the 3rd armed lever 4; Described detection agency, it comprises a replaceable probe 9, a slide-bar 10 and a slip pipe 11, on its slide-bar 10 1 ends replaceable probe 9 is installed, and its slide-bar 10 other ends are connected with the tooth bar 8 of actuating unit, its slip pipe 11 is installed on detection platform second armed lever 3, and its slide-bar 10 places in the slip pipe 11; Described single chip machine controlling circuit, it comprises that a control end, shows that output terminal, an input are provided with end, and its control end and two-way stepping motor 6 join, and its input is provided with the termination keyboard, and it shows output termination display.

During use, earlier initial value is set from keyboard, during detection, single chip machine controlling circuit drives two-way stepping motor 6 and rotates, and two-way stepping motor 6 driven gears 7 rotate, gear 7 is stirred tooth bar 8 and is taken place to bottom offset, slide-bar 10 slides from slip pipe 11, and replaceable probe 9 is inserted in the packing ring on first armed lever, the 2 front-end detection holes 5, and single chip machine controlling circuit writes down two-way stepping motor 6 rotation information in this process, the computing measured value, and take measured value and initial value relatively; If measured value equals initial value, illustrate that then the packing ring internal diameter is qualified; If measured value, illustrates then that the packing ring internal diameter is bigger than normal less than initial value; If measured value, illustrates then that the packing ring internal diameter is less than normal greater than initial value, and the letter of will being correlated with is wanted to be shown on the display.
