Description
Technical field
The present invention relates to detect device, in particular for the detection device of symmetric center of work piece deviation.
Background technology
Dimensional measurement is operation common, indispensable in industry manufacture field, and the requirement to measuring operation is more and more accurate.The workpiece with symmetrical feature grows on trees, and the symmetrical centre of these workpiece the most all occurs in every one procedure as reference element, therefore it whether accurate determines a workpiece, to a great extent even it may be said that the fine or not degree of a product quality.At present, measurement to this key element of symmetric center of work piece, the instrument, the method that use are not quite similar, workpiece accuracy requires the high high-accuracy measurer of employing, but high-accuracy measurer is expensive, and process of measurement is the most relative complex, required precision the most much higher employing tape measure, stamp the card, the numerical value measured is limited by working condition, and error is bigger.
Summary of the invention
The invention provides the detection device of a kind of symmetric center of work piece deviation, be used for overcoming shortcoming of the prior art, it is achieved simplify measuring process, reduce measurer cost.
The detection device of the symmetric center of work piece deviation that the present invention provides, workpiece to be detected is symmetrical work pieces, and this device has a strut, and described strut is respectively arranged at two ends with pin-and-hole, and this pin-and-hole is inserted into the bearing pin that two location holes symmetrically arranged with on workpiece to be detected coordinate；The centre of described strut is provided with measurement plate, and described measurement plate is provided with the scale groove overlapped with pin-and-hole symmetrical center positions described in two.
The present invention provides the detection device that symmetric center of work piece deviates, the bearing pin at strut two ends is inserted directly in symmetrically arranged two holes, location of workpiece to be detected, symmetrical work pieces is exactly to mark symmetric reference line on blank adding first operation in man-hour, mark the center, hole, location needing to process according to actual size referring next to this symmetric reference line, here " symmetrically arranged two holes, location " refer to that hole, two location opposite piece symmetric reference line is symmetrical arranged, by the symmetric reference line (symmetrical center line in i.e. two holes, location) on workpiece to be detected identified before processing is compareed with the scale groove measured on plate, i.e. can detect that whether the center of workpiece to be detected deviates, simple in construction, cost is relatively low, easy to use, different workpiece to be detected can be applicable to by the concrete size and structure changing bearing pin.

Detailed description of the invention
Embodiment one
As shown in Figure 1 and Figure 2, the present invention provides the detection device that a kind of symmetric center of work piece deviates, and this device has a strut 1, and strut is respectively arranged at two ends with pin-and-hole 2, and this pin-and-hole 2 is inserted into the bearing pin 3 that two location holes symmetrically arranged with on workpiece to be detected coordinate；The centre of strut 1 is provided with measurement plate 4, measures plate 4 and is provided with the scale groove 5 overlapped with two pin-and-hole symmetrical center positions.
As shown in Figure 6, the present invention provides the detection device of detection symmetric center of work piece deviation, the bearing pin at strut two ends is inserted directly in two holes, symmetrical location of workpiece 10 to be detected, by the symmetric reference line 20 being indicated on workpiece to be detected before processing is compareed with the scale groove 5 measured on plate, i.e. can detect that whether the symmetrical centre of workpiece to be detected deviates, simple in construction, cost is relatively low, easy to use, different workpiece to be detected can be applicable to by the concrete size and structure changing bearing pin, such as, the hole, location of workpiece to be detected is become square hole from circular hole, change circular shaft bearing pin into square shaft bearing pin can also use；The location bore dia of workpiece the most to be detected changes, and the size respective change of bearing pin also can also be used；But the pitch of holes of the two of workpiece to be detected hole, location changes, can not be continuing with by changing bearing pin, it is necessary to change strut.Scale groove 5 is exactly a common groove, the width of this groove is identical with the maximum deviation of work centre line to be detected, if the position of center line of workpiece to be detected is in this scale groove 5, then illustrate that the position of center line of workpiece to be detected is in the deviation range of regulation, it is qualified to be considered as, if the position of center line of workpiece to be detected is not in this scale groove 5, the position of center line deviation range beyond regulation of workpiece to be detected is then described, it is considered as defective, substantially increase detection speed, and simple in construction, easy to use, cost is relatively low.If the location hole size of workpiece to be detected or shape there occurs change, as long as changing bearing pin, it is not necessary to integral replacing detection device, the motility of use is higher.
Embodiment two
As shown in Figure 3-Figure 5, in order to improve the motility that the detection device of detection symmetric center of work piece deviation uses, this strut 1 is made up of the body of rod 11 and two key seats 6, and one end with key seat 6 respectively, the end of the body of rod 11 plugs together, and pin-and-hole 2 is located at the other end of this key seat 6.So, if two location pitchs of holes of workpiece to be detected change, can also continue to use by the body of rod 11.The cross section of the body of rod 11 is rectangular, and the end that key seat 6 coordinates with the body of rod 11 is provided with plug 61, plug 61 and key seat 6 and arranges and be provided with positioning step 62 between the end of pin-and-hole.Bearing pin 3 is fixed in pin-and-hole 2 by bolt 7.Install and change the most very convenient.
Last it is noted that various embodiments above is only in order to illustrate technical scheme, it is not intended to limit；Although the present invention being described in detail with reference to foregoing embodiments, it will be understood by those within the art that: the technical scheme described in foregoing embodiments still can be modified by it, or the most some or all of technical characteristic is carried out equivalent；And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of various embodiments of the present invention technical scheme.
