Description

Workpiece end face depth of parallelism detector
Technical field
The utility model relates to a kind of workpiece end face depth of parallelism detector.
Background technology
After machining, whether the depth of parallelism that needs to detect two opposing end surfaces reaches requirement to a lot of workpiece (as gear of the Internal and external cycle of bearing, various automobile, diesel engine etc.), if the depth of parallelism of two end faces is not up to standard, this workpiece is unacceptable product just.
At present, the measuring workpieces faces parallel generally is manual operations: be about to workpiece and be placed on the measuring table, the testing staff utilizes special distance measurement tools then, gather the distance between any three places on the workpiece both ends of the surface, three distances that will collect then compare to be checked, if the error of three data is within critical field, then this workpiece is certified products, otherwise is unacceptable product.This detection mode labor capacity is big, and work efficiency is extremely low, and the precision as a result of detection is not high yet.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of detection efficiency height, workpiece end face depth of parallelism detector that precision is high at above-mentioned prior art.
The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of workpiece end face depth of parallelism detector is characterized in that: comprise
Detection platform with planar support surface;
What be connected with detection platform can drive the driving mechanism that detection platform is rotated;
Be arranged on side, detection platform top, can contact with side surface of workpiece to be checked, at least two reference columns that workpiece to be checked is positioned;
Be arranged on detection platform top, contact with workpiece to be checked top end face, for detection of the measuring unit of the depth of parallelism between workpiece to be checked top end face and the bottom end face.
Described measuring unit can be clock gauge, and clock gauge is arranged on the detection platform top by adjuster bar; Described measuring unit also can be the combination of displacement transducer and the display element that is connected with displacement transducer.These two kinds of forms, all relatively more directly perceived to the measurement result demonstration of the depth of parallelism between workpiece to be checked top end face and the bottom end face, make things convenient for the testing staff to check.
As improvement, described detection platform is installed on the frame, and central rack is provided with a fixed head, and described driving mechanism is installed on this fixed head.
Preferably, described driving mechanism is motor, and the output shaft of motor connects with the main shaft of detection platform by turning axle.
Improve again, the motor speed-regulating switch that links to each other with described motor is installed on the described frame.
Compared with prior art, advantage of the present utility model is: the workpiece end face depth of parallelism detector that uses the utility model to provide, as long as workpiece to be checked is placed on the detection platform, driving mechanism can drive detection platform and rotate, in the detection platform rotation process, because the location of reference column is arranged, workpiece to be checked can rotate together along with detection platform, the measuring unit that be arranged on workpiece to be checked top end face this moment just can come out the depth of parallelism visual inspection between workpiece to be checked top end face and the bottom end face, the utility model is simple in structure, easy to operate, the precision height.
Description of drawings
Fig. 1 is the structural representation of workpiece end face depth of parallelism detector among the utility model embodiment one;
Fig. 2 is the structural representation of workpiece end face depth of parallelism detector among the utility model embodiment two.
Embodiment
Describe in further detail below in conjunction with the utility model of accompanying drawing embodiment.
Embodiment one
Workpiece end face depth of parallelism detector as shown in Figure 1, it comprises
Frame 1, frame 1 middle part is provided with fixed head 2, fixed head 2 belows are equipped with motor 3, frame 1 top is provided with the detection platform 4 with planar support surface, the output shaft of motor 3 connects with the central principal axis 41 of detection platform 4 by turning axle 5, frame 1 side is equipped with the motor speed-regulating switch 6 that links to each other with motor 3, it can be the dog screw of two adjustable distances with workpiece 7 contacts side surfaces to be checked, for 8, two reference columns of two reference columns 8 that workpiece to be checked is positioned that side, detection platform top is provided with; That detection platform top arranges, contacts with workpiece to be checked top end face, for detection of the measuring unit of the depth of parallelism between workpiece to be checked top end face and the bottom end face, measuring unit is clock gauge 9 in the present embodiment, and the gauge head of clock gauge 9 generally is lower than about measured workpiece end face 0.2mm.
During work, open motor 3, motor 3 drive detection platform 4 are done continuously and are rotatablely moved, be placed on workpiece for measurement 7 on the detection platform 4 this moment, workpiece for measurement 7 is because deadweight can be adjacent to the planar support surface of detection platform 4, at this moment detection platform 4 can drive measured workpieces and does synchronously and rotatablely move, and workpiece for measurement can be done synchronously by two reference columns, 8 location and along the central shaft of detection platform 4 and rotatablely moves.The position of the clock gauge on the detection platform 4 can be regulated by adjuster bar, so just can satisfy different measured workpiece height requirement.The variation of clock gauge pointer is the jerk value of measured workpiece end face.Whether the tester watches the variation of clock gauge pointer to get final product in error range as long as measured workpiece steadily is placed on the detection platform 4 simultaneously.The workpiece parallelism precision that this mode detects can reach 2 μ m.
Embodiment two
Different with embodiment one is that measuring unit comprises displacement transducer 10 and the display element 11 that is connected with displacement transducer, referring to shown in Figure 2.
