Abstract
The utility model discloses a laser detector by workpiece projecting size, which comprises a stand, a measurer placement seat arranged on the stand and a laser detector; wherein, the laser detector comprises a laser transmitter, a laser receiver and a digital signal processor; the laser transmitter and the laser receiver are respectively positioned at both sides of the measurer placement seat in the back and forth shifting direction; the utility model is characterized in that the measurer placement seat is installed on the slide block of a line guide rail; the measurer placement seat is controlled by an actuator, and measurer placement seat is moved back and forth along the line guide rail; a plane that is formed by the parallel laser light generated by the laser transmitter is perpendicular to the line guide rail; the laser transmitter and the laser receiver can be moved up and down along the direction that is perpendicular to the stand. The utility model has the advantages of wide detection range and high detection precision.
Description
Technical field
The utility model relates to a kind of laser detector, is a kind of laser detector that is used to detect the workpiece projection size specifically.
Background technology
At present, existing laser detector is simply detected material to be placed in the detection zone, sending a branch of parallel beam by the generating laser in the laser detector shines object, when running into object, parallel beam lived by shelves, form and the measure-alike projection dark space of testee, laser pickoff receives, and proportional meter bright, the dark space is calculated the projection size of object.Laser detection precision height but measurement range is little, just need wide-measuring range more for the object of big part or two cover laser detectors.Though can reach the purpose that detects big part object, but increased the cost of product, make system become complicated simultaneously, in addition,, and just can not in time handle for just can not directly having measured for the device of two cover laser detection for a large amount of objects that will detect greater than sensing range and less than the object of two laser interband distances.
Summary of the invention
The purpose of this utility model provides the workpiece projection size laser detector that a kind of sensing range is wide, accuracy of detection is high.
The utility model is achieved through the following technical solutions.
A kind of workpiece projection size laser detector, comprise support, be arranged on to be measured placement rack and laser detector on the support, wherein laser detector comprises generating laser, laser pickoff and signal processor, generating laser and laser pickoff lay respectively at the both sides that to be measured placement rack moves forward and backward direction, it is characterized in that: described to be measured placement rack is installed on the slide block of a straight line guide rail, to be measured placement rack moves around by actuator control and along line slideway, and the formed plane of the parallel laser that generating laser sends is perpendicular to line slideway; Described generating laser and laser pickoff can move up and down along the direction perpendicular to support.
Described support is provided with installing plate, and laser detector is arranged on the installing plate, and laser detector can move up and down on installing plate.
One side of described to be measured placement rack is provided with the workpiece angle roll-over table, can be to the detection of the projection size of workpiece different angles.
Described support is provided with workpiece and send the part mechanical arm automatically.
Described pick-up unit also comprises mechanism controls device and computer software.
The utility model compared with prior art has the following advantages.
Generating laser and laser pickoff in the workpiece projection size laser detector described in the utility model can move up and down along the direction of vertical table-board and workpiece be detected, when object to be detected during greater than sensing range, by moving, segmentation detects, and indirect detection is to the accurate dimension of workpiece; By moving of to be measured placement rack, can detect the workpiece diverse location; Detect after making Workpiece Rotating arbitrarily angled by the angle whirligig, can detect workpiece projection size at any angle.Testing process full automation of the present utility model, and dispose accurate localization control and computer control processing, can obtain accurate data and further handle.
Description of drawings
Fig. 1 is the assembly structure synoptic diagram of the utility model workpiece projection size laser detector.
Embodiment
Below in conjunction with accompanying drawing the utility model workpiece projection size laser detector is described in further detail.
As shown in Figure 1, automatically workpiece is put on to be measured the placement rack 2 from sending the part guide rail to take out by mechanical arm 1, by dragging system to be measured placement rack 2 moved through the wicket 41 of installing plate 4 centres and deliver to the laser detection district along guide rail 3, by moving to be measured placement rack 2, make laser detector 5 measure the projection size value of the diverse location of workpiece.To be measured placement rack 2 moved to workpiece angle roll-over table 6 places again, Workpiece Rotating arbitrarily angled after, send the laser detection district again back to and measure again, and data are sent to computer handle.After detection is finished, move to be measured placement rack 2 and get back to mechanical arm pickup position, and workpiece is passed out to out on the part track, finish a sense cycle.
