The present application will be described in further detail below with reference to the accompanying drawings by way of specific embodiments.
Referring to fig. 1 to 5, the workpiece surface mapping apparatus provided in this embodiment includes: a first guide 10, a first slide 20, a second guide 30, a second slide 40, a measuring head 50, and a scribe pen 60.
The length direction of the first guide part 10 is a first linear direction, and the first sliding part 20 is slidably disposed on the first guide part 10, that is, the first sliding part 20 can slide reciprocally along the length direction of the first guide part 10, so that the first sliding part 20 and the first guide part 10 form a sliding pair to output a reciprocating motion along the first linear direction. In this embodiment, the power for the first sliding part 20 to slide back and forth along the first guide part 10 may be manually pushed, or may be provided by means such as rack and pinion, sprocket chain, or the like. In a preferred embodiment, the power of the first sliding part 20 sliding back and forth along the first guide part 10 is manually pushed.
The second guide portion 30 is disposed on the first sliding portion 20, and the length direction of the second guide portion 30 is a second linear direction, and the second sliding portion 40 is slidably disposed on the second guide portion 30, that is, the second sliding portion 40 can slide reciprocally along the length direction of the second guide portion 30, so that the second sliding portion 40 and the second guide portion 30 form a sliding pair to output a reciprocating motion along the second linear direction. In this embodiment, the power for the second sliding portion 40 to slide back and forth along the second guide portion 30 may also be manually pushed, or may be provided by means such as rack and pinion, chain and sprocket. Of course, in the preferred embodiment, the power of the second sliding part 40 sliding back and forth along the second guide part 30 is manually pushed.
In the above embodiment, the second linear direction does not intersect and is not parallel to the first linear direction, that is, the second guide portion 30 and the first guide portion 10 do not spatially interfere with each other, so that the first sliding portion 20 and the second sliding portion 40 can be ensured to do not interfere with each other in the respective sliding directions.
A measuring head 50 is disposed at one end of the second sliding portion 40 along the second linear direction, the measuring head 50 being configured to contact the curved surface 101 of the workpiece 100 to be measured.
The scribing pen 60 is provided in the vertical direction, and the scribing pen 60 is provided at the other end of the second sliding portion 40 in the second linear direction, the scribing pen 60 being used for drawing on the drawing paper.
The workpiece curved surface mapping device has the following specific using process:
keeping the first guide portion 10 in the horizontal plane (i.e. the first linear direction is in the horizontal plane), pushing the other end of the second sliding portion 40 causes the second sliding portion 40 to slide along the second linear direction from the other end to one end of the second sliding portion 40, so that the measuring head 50 contacts the curved surface 101 of the workpiece 100 to be measured, and then pushing the first sliding portion 20 causes the first sliding portion 20 to slide on the first guide portion 10 along the first linear direction, and during the sliding of the first sliding portion 20 on the first guide portion 10 along the first linear direction, always applying a pushing force to the other end of the second sliding portion 40 ensures that the measuring head 50 always contacts the curved surface 101 of the workpiece 100 to be measured, that is, the measuring head 50 moves on the curved surface 101 along with the movement of the second sliding portion 20. The marker 60 on the end of the second sliding portion 40 can draw a curve on the drawing sheet, which is a curved section where the horizontal plane coincides with the curved surface 101. Then, the height of the first guide part 10 is adjusted up or down (to be kept parallel to the previous horizontal plane), and the previous process is repeated to draw another curve. After the plurality of curves are drawn in sequence, whether the curved surface on the workpiece to be measured is qualified or not can be judged through the drawn curves. The whole mapping process is convenient and simple to operate.
In the above embodiment, in order to ensure that the measuring head 50 can move smoothly on the curved surface 101, a ball may be disposed at a contact end of the measuring head 50 and the curved surface 101.
Of course, before the workpiece curved surface surveying and mapping device is used for surveying and mapping, the scribing pen 60 needs to firstly scribe lines on the drawing paper by pushing the first sliding part 20 and the second sliding part 40, so as to ensure that the scribing effect is normal.
It should be noted that the curved surface 101 of the workpiece 100 to be measured includes an inner concave curved surface and an outer convex curved surface, when the measuring head 50 contacts the inner concave curved surface, the measuring head 50 contacts the highest point of the inner concave curved surface first, and it is ensured that the second guiding portion 30 also has a margin for the second sliding portion 40 to continue to slide toward the lowest point of the inner concave curved surface. Accordingly, when the measuring head 50 contacts the convex curved surface, the measuring head 50 first contacts the lowest point of the convex curved surface, and it is also necessary to ensure that the second guide portion 30 still has a margin for the second sliding portion 40 to continue sliding toward the highest point of the convex curved surface.
In one embodiment, the apparatus for mapping a curved surface of a workpiece further comprises: an elastic member 70, the elastic member 70 being used to always provide a pushing force to the second sliding portion 40 during the sliding of the first sliding portion 20 on the first guide portion 10 in the first linear direction, so that the second sliding portion 40 can always maintain a tendency in a direction from the other end to the one end thereof. Correspondingly, a limiting portion 81 is disposed on the second sliding portion 40, the limiting portion 81 is located between the first sliding portion 20 and one end or the other end of the second sliding portion 40, the elastic element 70 is disposed between the limiting portion 81 and the first sliding portion 20, two ends of the elastic element 70 can be respectively fixed on the limiting portion 81 and the first sliding portion 20, or one end of the elastic element 70 abuts against the limiting portion 81, and the other end abuts against the first sliding portion 20.
Of course, during the sliding of the first sliding part 20 on the first guiding part 10 along the first linear direction, it is necessary to ensure that the elastic member 70 is always in a compressed state, so as to ensure that the measuring head 50 always contacts the curved surface 101.
