The fixed-time online display screen workpiece detector comprises a detector main machine, wherein the detector main machine comprises a fixed-time lens arranged at the lower part and a lighting sleeve which is arranged at the periphery of the fixed-time lens, the end part of the lighting sleeve is provided with an LED (light-emitting diode) lighting assembly, a group of laser emitters are symmetrically arranged at the two sides of a central axis of the fixed-time lens, and an intersection point of laser beams emitted by the two laser emitters is arranged on the central axis of the fixed-time lens. According to the utility model, visual reference is provided for a user by virtue of dual-laser irradiation light spots, whether a set object distance is achieved is judged according to the fact that whether laser light spots are coincided or not, and convenience is provided for an operator, thus the operator is easier to grasp the measuring instrument, and workpiece detection accuracy can be beneficially guaranteed and improved.

Description

A kind of fixed doubly online screen workpiece sensing appearance that shows

Technical field

The utility model belongs to measuring equipment and Instrument technology field, relates to a kind of measuring appliance of online detection workpiece, is specifically related to a kind of fixed doubly online screen workpiece sensing appearance that shows.

Background technology

Detector was to trigger image automatically to show when conventional online was looked the detection of screen workpiece sensing appearance, regulated the detector height after promptly workpiece is fixed and made object distance in the 0.1mm error range of setting object distance, can trigger industrial camera and display screen show image; And only when actual object distance equaled to set object distance, image was the most clear, and enlargement ratio is the most accurate, and promptly accuracy of detection is best.And at present; Existing detector is in detection; Adopt the mode dependence experience of manual adjustments to feel to come the instrumentality distance, be adjusted to earlier in the scope that triggers image, and then finely tune again with the sharpness of visual inspection show image; Very difficult for operator especially neophyty operation person like this; Because image definition is difficult to the naked eye distinguish in error range, so artificial subjective factor is very big to the testing result influence, and the possibility of result difference even difference that different personnel is come out to same workpiece sensing are very big.Therefore, even when being adjusted in the scope that can trigger image, can't guarantee that also object distance is setting value just, still have the error of 0.1mm after all, this brings uncertainty just for the result of workpiece sensing, and ten minutes influences accuracy of detection.

The utility model content

The purpose of the utility model provides and overcomes the existing fixed doubly online above-mentioned weak point of showing screen workpiece sensing appearance, and a kind of fixed doubly online screen workpiece sensing appearance that shows with two laser positioning object distances is provided.

The technical scheme that the utility model adopted is; A kind of fixed doubly online screen workpiece sensing appearance that shows; It has a detector main frame; This detector main frame comprises the fixed times camera lens that is arranged on the bottom and is arranged on the illumination sleeve that fixed times camera lens periphery and end are equipped with the LED light fixture, be along the both sides, axis of said fixed times camera lens to be provided with two generating lasers symmetrically, and these two generating laser emitted laser cross-overs is positioned on the axis of said fixed times camera lens.

Described two generating lasers are installed in the outside of illumination sleeve respectively through a transmitter rack; This transmitter rack has connecting portion that is connected with the illumination sleeve outer wall and the transmitter installation portion that generating laser is installed, and offers the through hole that supplies laser beam to pass on the said illumination sleeve.

Sheathing is also established in periphery in said illumination sleeve, generating laser and transmitter rack, and laser switch is installed on the sheathing.

The utility model provides visual reference through two laser radiation hot spots to the user; Whether judge through the coincidence of laser facula whether object distance reaches the setting object distance; Offer convenience to the operator, make more easy master of operator, also help guaranteeing and improving simultaneously the precision of workpiece sensing.

Fig. 2 is the utility model broken section structural representation.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.

Like Fig. 1, shown in Figure 2; The described fixed doubly online screen workpiece sensing appearance that shows of the utility model has a detector main frame 1; This detector main frame 1 comprises the fixed times camera lens 2 that is arranged on the bottom and is arranged on the illumination sleeve 3 that fixed times camera lens 2 peripheries and end are equipped with the LED light fixture; Be along the both sides, axis of said fixed times camera lens 2 and be provided with two generating lasers 4 symmetrically, and these two generating lasers, 4 emitted laser cross-overs are positioned on the axis of said fixed times camera lens 2.Particularly; Described two generating lasers 4 are installed in the outside of illumination sleeve 3 respectively through a L-shaped transmitter rack 5, this transmitter rack 5 has and illumination sleeve 3 outer walls connecting portion 51 that is connected and the transmitter installation portion 52 that generating laser 4 is installed; And offer the through hole 30 that supplies laser beam to pass on the said illumination sleeve 3.

Through said structure, axis and the two laser of fixed times camera lens 2 intersect at a point 40 simultaneously in the utility model, through regulating the angle of inclination of generating laser 4, can control this point 40 distance of object lens in times camera lens 2 calmly and equal the object distance set just; Therefore; When the user the height of regulating detector be instrumentality apart from the time; Driving generating laser 4 moves up and down; Therefore the facula position that on workpiece, forms of the light beam irradiates of two generating lasers 4 also changes thereupon, and when the hot spot of two bundle laser radiations on workpiece had two, object distance was greater than or less than and set object distance this moment; Have only when two hot spots coincidences are a hot spot; Object distance side equals to set object distance, and therefore, the utility model provides visual reference through two laser radiation hot spots to the user; Whether judge through the coincidence of laser facula whether object distance reaches the setting object distance; Offer convenience to the operator, make more easy master of operator, also help guaranteeing and improving simultaneously the precision of workpiece sensing.

In addition; Sheathing 6 is also established in periphery in said illumination sleeve 3, generating laser 4 and transmitter rack 5; Laser switch 61 is installed on the sheathing 6, and sheathing 6 plays the effect that covers generating laser 4 and transmitter rack 5, makes the detector overall appearance more succinct.

Multiplying power according to fixed times camera lens 2 is different, and it is also different to set object distance, and promptly the generating laser irradiating angle is also different, can set object distance through its angle of inclination of adjustment.

Above-mentioned embodiment is an instance of the utility model; Not enforcement and the interest field that is used for limiting the utility model; All equivalences of making according to the described content of the utility model patent protection scope change and modify, and all should be included in the utility model claim.
