Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required to be used in the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
Fig. 1 is a schematic perspective view of a portable symmetry detecting apparatus according to an embodiment of the present invention;
in the figure:
1. measuring a reference plate; 2. a vertical direction optical axis; 3. adjusting knobs up, down, left and right; 4. a lengthwise stepped shaft; 5. and (4) a dial indicator.
Detailed Description
For further explanation of the embodiments, the drawings are provided as part of the disclosure and serve primarily to illustrate the embodiments and, together with the description, to explain the principles of operation of the embodiments, and to provide further explanation of the invention and advantages thereof, it will be understood by those skilled in the art that various other embodiments and advantages of the invention are possible, and that elements in the drawings are not to scale and that like reference numerals are generally used to designate like elements.
According to the utility model discloses an embodiment provides a portable symmetry detection device.
Example (b):
as shown in fig. 1, a portable symmetry detection device, including measuring reference plate 1, be equipped with the screw hole on measuring reference plate 1, measuring reference plate 1's one end is connected with vertical direction optical axis, be provided with about vertical direction optical axis 2 on adjust knob 3, vertical direction optical axis 2's the other end is connected with length direction step shaft 4, length direction step shaft 4's one end is equipped with locking screw, length direction step shaft 4's one end is connected with percentage table 5 through locking screw.
The measuring reference plate 1 is used for clinging to the upper surface and the lower surface of the key slot chock.
The dial indicator 5 is provided with a large dial plate on the inner and outer rings, and a small dial plate is arranged in the large dial plate.
The up-down and left-right adjusting knobs 3 are used for adjusting the angle and position of the detection device.
With the aid of the technical scheme, the utility model discloses an operating procedure is as follows: firstly, a user selects a corresponding key slot plug gauge according to the specification of a key slot of a product, performs point inspection on a dial indicator 5, determines that the key slot plug gauge is available for OK, then lightly slides the key slot plug gauge into the key slot, selects the following two different measurement modes according to different specific conditions, generally adopts a mode of placing the product on a deflection instrument and jacking up the product by two tops on a production line, and adopts a mode of fixing the product on a measurement reference plate 1 by hands by OQC (shipment quality control).
If the user adopts the mode of jacking the product on the deflection instrument by two centers, the user puts the pointer of the dial indicator 5 on the key slot plug gauge, rotates the product by the upper, lower, left and right adjusting knobs 3, pulls the gauge stand back and forth to find the balance point, when the size is always kept unchanged, the point is the balance point, records the reading to be compared with the data measured on the other side, the small dial plate is read firstly and then the large dial plate is read, then the user lifts the pointer of the dial indicator 5, rotates the product by 180 degrees by the upper, lower, left and right adjusting knobs 3, then the balance point is found, the other side of the key slot is measured according to the same method, the readings on the two sides are compared, the difference between the two values is the measured value of the symmetry degree, finally, the user respectively measures the symmetry degree of the head and the tail of the key slot according to the method, the symmetry degree of the head and the tail of the two points is, and judging the symmetry degree OK of the key groove, otherwise, judging the key groove to be NG.
If the user fixes the product on the measuring reference plate 1 by hand, the user places the pointer of the dial indicator 5 on the outer diameter of the product, the base of the dial indicator 5 is placed on the keyway plug gauge, the dial indicator 5 is moved back and forth to measure on the shaft diameter, when the size is kept unchanged all the time, the reading is recorded so as to compare with the data measured on the other side, then the user takes up the dial indicator 5, the product is rotated by 180 degrees through the up-down left-right adjusting knob 3, the other side of the keyway is measured according to the same method, the readings on the two sides are compared, the difference value between the two is the measured value of the symmetry, finally, the user respectively measures the symmetry on the head and the tail of the keyway according to the method, the symmetry values of the head and the tail are both OK, the symmetry of the keyway is judged to be OK, otherwise, the result is judged to be NG.
When using the device, it should be noted that the following matters can ensure a longer service life of the device:
1. cleaning the central hole and the key groove before measurement to avoid foreign matters;
2. when the product is rotated, attention needs to be paid to a dial indicator, so that a measurement error caused by collision is avoided;
3. after the measurement is finished, the key slot plug gauge is put back into the measuring tool box, and random placement is not allowed.
The portable symmetry degree detection device is suitable in size and convenient to carry, the device is fine in scale, the size of the key groove can be measured more accurately, operation methods are unified according to correct operation steps, equipment is used correctly, workpiece measurement accuracy can be guaranteed, and the service life of the equipment is prolonged.
