Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, the utility model discloses a one-way measuring device of contact comprises backup pad 1, guide rail 2, slider 3, sliding body 4, cylinder 5, contact gauge head 6, keysets 7.
The guide rail 2 is fixed on the support plate 1, and the back of the support plate 1 is provided with an adapter plate 7. The cylinder 5 is mounted on the support plate 1 through an upper foot rest 8 and a lower foot rest 9 and is parallel to the guide rail 2. The sliding body 4 is formed by fixedly connecting a sliding block connecting plate 41 and a measuring head connecting plate 42, wherein the sliding block connecting plate 41 acts on the guide rail 2 through the sliding block 3, the measuring head connecting plate 42 is connected with the output end of the air cylinder 5 through the floating joint 10, and the sliding body 4 can move up and down along the guide rail 2 under the action of the air cylinder 5.
