Abstract
The invention discloses a device for detecting deviation of the symmetric center of a work piece. A work piece to be detected is a symmetric work piece. The device has a jackstay, the two ends of the jackstay are respectively provided with a pin hole, and pin shafts matched with two positioning holes symmetrically arranged on the work piece to be detected are inserted in the pin holes. The middle of the jackstay is provided with a measuring plate, and the measuring plate is provided with a scale groove which coincides with the position of the symmetric center of the two pin holes. During use, the pin shafts at the two ends of the jackstay are directly inserted in the two symmetrical positioning holes of the work piece to be detected, and whether the center of the work piece to be detected is deviated can be detected by comparing a base line which is marked on the work piece to be detected before processing and the scale groove on the measuring plate. The device has the advantages of simple structure, low cost and easy use and can be applicable to different work pieces to be detected by changing the specific size and the structure of the pin shafts.
Description
Technical field
The present invention relates to pick-up unit, the pick-up unit departing from particular for workpiece symcenter.
Background technology
Dimensional measurement is operation common, indispensable in industry manufacture field, more and more accurate to the requirement of measurement operation.The workpiece with symmetrical feature grows on trees, and the symcenter of these workpiece often all appears in each procedure as reference element, so it whether accurate determined to a great extent a workpiece, even can say the fine or not degree of a product quality.At present, measurement to this key element of workpiece symcenter, the instrument, the method that adopt are not quite similar, workpiece accuracy requires the high-accuracy measurer of high employing, but high-accuracy measurer is expensive, and process of measurement is relative complex also, the not much higher employing tape measure of accuracy requirement, stamp the card etc., measure the numerical value coming and limit by working condition, error is larger.
Summary of the invention
The invention provides the pick-up unit that a kind of workpiece symcenter departs from, for overcoming shortcoming of the prior art, realize simplified measurement step, reduce measurer cost.
The pick-up unit that workpiece symcenter provided by the invention departs from, workpiece to be detected is symmetrical work pieces, this device has a strut, and described strut two ends are respectively equipped with pin-and-hole, is inserted with and bearing pin that on workpiece to be detected, symmetrically arranged two pilot holes coordinate in this pin-and-hole; The centre of described strut is provided with measurement plate, the scale groove that described measurement plate is provided with described in two, pin-and-hole symcenter position overlaps.
The invention provides the pick-up unit that workpiece symcenter departs from, the bearing pin at strut two ends is directly inserted in symmetrically arranged two pilot holes of workpiece to be detected, symmetrical work pieces marks symmetrical datum line exactly adding man-hour first operation on blank, then with reference to this symmetry datum line, according to physical size, mark the pilot hole center that needs processing, here " symmetrically arranged two pilot holes " refer to that two symmetrical datum lines of the relative workpiece of pilot hole are symmetrical arranged, by the symmetrical datum line (i.e. the symmetrical center line of two pilot holes) being identified at before processing on workpiece to be detected is contrasted with the scale groove of measuring on plate, whether depart from the center that can detect workpiece to be detected, simple in structure, cost is lower, easy to use, by changing concrete size and the structure of bearing pin, can be applicable to different workpiece to be detected.

Embodiment
Embodiment mono-
As shown in Figure 1 and Figure 2, the invention provides the pick-up unit that a kind of workpiece symcenter departs from, this device has a strut 1, and strut two ends are respectively equipped with pin-and-hole 2, is inserted with and bearing pin 3 that on workpiece to be detected, symmetrically arranged two pilot holes coordinate in this pin-and-hole 2; The centre of strut 1 is provided with measures plate 4, measures plate 4 and is provided with the scale groove 5 overlapping with two pin-and-hole symcenter positions.
As shown in Figure 6, the invention provides and detect the pick-up unit that workpiece symcenter departs from, the bearing pin at strut two ends is directly inserted in two symmetrical pilot holes of workpiece 10 to be detected, by the symmetrical datum line 20 being indicated in before processing on workpiece to be detected is contrasted with the scale groove 5 of measuring on plate, whether the symcenter that can detect workpiece to be detected departs from, simple in structure, cost is lower, easy to use, by changing concrete size and the structure of bearing pin, can be applicable to different workpiece to be detected, for example, the pilot hole of workpiece to be detected becomes square hole from circular hole, changing circular shaft bearing pin into square shaft bearing pin can also use, the pilot hole diameter of workpiece to be detected changes for another example, and the size respective change of bearing pin also can also be used, but the pitch of holes of two pilot holes of workpiece to be detected changes and can not continue to use by changing bearing pin, must 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, 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, illustrate that the position of center line of workpiece to be detected has exceeded the deviation range of regulation, be considered as defective, greatly improved detection speed, and simple in structure, easy to use, cost is lower.If there is variation in pilot hole size or the shape of workpiece to be detected, as long as change bearing pin, needn't integral replacing pick-up unit, the dirigibility of use is higher.
Embodiment bis-
As shown in Figure 3-Figure 5, in order to improve, detect the dirigibility that pick-up unit that workpiece symcenter departs from is used, this strut 1 consists of the body of rod 11 and two key seats 6, and body of rod 11 end plugs together with one end of key seat 6 respectively, and pin-and-hole 2 is located at the other end of this key seat 6.Like this, if two pilot hole spacing of workpiece to be detected change, by the body of rod 11, can also continue to use.The xsect 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, and plug 61 and key seat 6 arrange between the end of pin-and-hole and be provided with positioning step 62.Bearing pin 3 is fixed in pin-and-hole 2 by bolt 7.Install and change all very convenient.
Finally it should be noted that: each embodiment, only in order to technical scheme of the present invention to be described, is not intended to limit above; Although the present invention is had been described in detail with reference to aforementioned each embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or some or all of technical characterictic is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the scope of various embodiments of the present invention technical scheme.
